Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening adjusting means for changing and adjusting a leak opening in a swing sorting section for sorting and processing a processed material leaked from a handling room, and a process for leaking from the handling room. A processing object amount detecting means for detecting an amount of the object, and the opening amount is set based on the detection information of the processing object amount detecting means so that the leakage opening degree becomes a target leakage opening degree which increases as the amount of the processing object increases. And a control means for operating the degree adjusting means.

[0002]

2. Description of the Related Art In such a threshing apparatus, conventionally,
On the basis of the detection information of the processed material amount detection means, the leakage opening of the swing sorting unit is adjusted to a target leakage opening that increases as the amount of processed material leaked from the handling room increases. That is,
If the amount of material leaked from the handling room increases, the leakage opening increases, while if the amount of material leaking from the handling room decreases, the opening of the leakage decreases. Is performed properly.

[0003]

However, when the amount of material leaked from the handling room is reduced, the leak opening is controlled to be reduced accordingly. When the amount of material becomes extremely small, the leakage opening decreases, and the amount of processed material on the swing sorting unit decreases, a small amount of processed material jumps with the swing of the swing sorting unit. There is a problem that it is difficult for the object to leak from the swing sorting unit, and it is easy to scatter from the dust outlet to the outside together with, for example, straw waste, so-called third loss increases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the problem that the third loss increases when the amount of the material to be leaked from the handling room decreases.

[0005]

According to the first aspect of the present invention, the detected amount of the processing object detected by the processing object amount detecting means is equal to or less than the set amount, and the leakage opening degree becomes small. In the state of being adjusted to a predetermined working condition, the leak opening is adjusted so as to be a set leak opening larger than the target leak opening corresponding to the detected processed material amount. Therefore, the processed material to be sorted easily leaks from the swinging sorting unit, and it is possible to suppress the processed material from scattering to the outside. Therefore, it is possible to solve the problem that the third loss increases when the amount of the material leaked from the handling room decreases.

According to the characteristic configuration of the present invention, a traveling device is provided, such as a combine, so that the culm is cut while traveling and the cut culm is supplied to the handling room. When the detection information of the work state detection means is switched from the reaping work state to the non-rearing work state, the driving of the traveling device is stopped, so that the predetermined work condition is satisfied. It is configured. In other words, in a combine harvester or the like, when it is in a non-cutting work state, the amount of the processed material leaking from the handling room is sharply reduced, and the processed material remaining in the swing sorting unit easily jumps and scatters to the outside. Therefore, the third loss is likely to occur, but in the non-cutting work state, especially when the running is stopped, the processed material scattered outside falls to the same place, so that However, there is a possibility that an impression that the third loss is large in appearance may be given. Therefore, by adopting the characteristic configuration according to claim 2, it is possible to reduce the third loss when the traveling is stopped in the non-cutting work state in a combine or the like, and
It is possible to prevent giving an impression that there is much third loss.

According to the third aspect of the present invention, when the set time elapses after the detection information of the work state detecting means is switched from the reaping work state to the non-rearing work state, leakage of the rocking sorting unit occurs. The opening is adjusted so as to reach the target leakage opening. In other words, as the time elapses in the non-cutting operation state, the amount of the processed material remaining in the swing sorting unit decreases, and the effectiveness of the opening operation control in suppressing the third loss decreases. Therefore, by adopting the characteristic configuration according to claim 4 and appropriately setting the set time, it is possible to prevent the execution of the opening operation control despite the small effectiveness. In response to the switching from the non-cutting operation state to the cutting operation state, the opening operation control is changed to the normal opening adjustment control for adjusting the leak opening to the target leak opening according to the detected processing amount. A manual operation for switching can be omitted. Also, in combine etc.
In a state of stopping at the headland, there is a case where the so-called pillow threshing is performed by directly supplying the grain culm to the handling room and threshing, but the pillow threshing is also performed by adopting the characteristic configuration according to claim 4. This can be performed without switching from the opening operation control to the normal opening control.

According to the fourth aspect of the present invention, the wind power of the turtle is adjusted to the minimum value as the detection information of the work state detecting means is switched from the cutting work state to the non-cutting work state. Therefore, it is possible to suppress the processed material from being blown out to the outside by the wind power of the turtle. Therefore, in combine harvesting and the like, it is possible to further suppress the third loss in the non-cutting operation state.

According to the fifth aspect of the present invention, the set leakage opening can be changed and set, so that in the opening operation control, the third loss can be appropriately selected while minimizing the third loss. The leak opening can be adjusted to allow for processing. In other words, as the leak opening is increased, the third loss can be suppressed, but conversely, the sorting performance decreases as the leak opening increases, so that the third loss is suppressed as much as possible. The setting of the set leak opening can be changed so that the sorting process can be properly performed.

And a second product collection unit (hereinafter, referred to as a second port) 21.

As shown in FIG. 5, a mechanism is provided at the upper part of the feed chain 16 for pressing the grain culm to be conveyed downward and holding it with the feed chain 16. That is, the plurality of pressing members 16a and 16b connected in the transport direction by the pivot shaft P are separately elastically urged by the coil spring 16c. A potentiometer S1 is provided for detecting the upward displacement of the pivot shaft P between the first pressing member 16a and the second pressing member 16b from the front. The thickness of the grain culm sandwiched between the feed chain 16 and the pressing members 16a and 16b is detected by the potentiometer (hereinafter referred to as a culm thickness sensor) S1, and the conveying speed of the feed chain 16 is kept substantially constant. Therefore, the detection value of the culm thickness sensor S1 is proportional to the amount of grain culm supplied to the handling room A.

The grain culm supplied and transported to the handling room A by the feed chain 16 is threshed by the rotation of the handling drum 15. A receiving net 22 is provided in the lower part of the handling room A, and a single grain of the processed material after threshing leaks from the receiving net 22 to the swing sorting plate 19. Processed materials that could not be leaked from the receiving network 22
From the rear end part of the swing sorting plate 19.

The swing sorting plate 19 is composed of a grain pan 23 located above the tongue 18, a chaff sheave 24 located behind it, a Glen sheave 25 located below it, and the like. The first port 20 and the second port 21 are each provided with a screw conveyor, and the grains leaked from the grain sieve 25 are collected from the first port 20 and stored in a tank or the like. The mixture of the grain and the straw chips dropped from the rear end of the chaff sheave 24 or the rear end of the Glen sheave 25 is collected from the second port 21 and returned to the swinging sorting plate 19.

The chaff sheave 24 is, as shown in FIG.
A plurality of plate members 24a are arranged in the front-rear direction at predetermined intervals. Each plate-like member 24a is pivotally attached to the left and right side plates so as to be rotatable around the left and right axes, and the lower end is provided with a link 24b.
It is pivotally connected at. Therefore, when the link 24b is moved in the front-rear direction, the respective plate members 24a are simultaneously rotated, and the adjacent distance t between the respective plate members 24a is changed. This interval t corresponds to the leakage opening (chaff opening) of the processed material on the swing sorting plate 19.

The adjustment of the leak opening is performed by changing the rotational direction of the sheave motor M1 as the opening adjusting means in the forward and reverse directions. The forward / reverse rotation of the sheave motor M1 is performed by a gear-type linkage mechanism 26, a swing arm 27, a wire 2
8 to convert the link 24b back and forth to change the leak opening as described above. It should be noted that a potentiometer-type chaff opening sensor S2 for detecting the leakage opening from the rotation angle of the swing arm 27 is provided.

The tow 18 is for generating a sorting wind for blowing off the straw chips on the swinging sorting plate 19, and the wind force (hereinafter referred to as a toumi wind force) is adjusted by adjusting the rotation speed of the toumi 18 (hereinafter, referred to as a towing wind). This is performed by changing the torsion speed. As shown in FIG. 7, the input pulley 18a for rotating and driving the torsion 18 is constituted by a split pulley,
The effective diameter is changed by the forward / reverse driving of the torsion motor M2 as the wind force adjusting means. That is, the torsion motor M2
Is driven forward, the gear-type linkage mechanism 30 and the swing arm 3
1. The arm 33 is pulled through the wire 32, and the interval between the split pulleys 18a is widened by a cam mechanism (not shown). As a result, the effective diameter of the portion where the V-belt 18b comes into contact is reduced, the rotation speed of the toumi is increased, and the wind power of the toumi is increased. When the torsion motor M2 is reversed, each part moves in the opposite direction to the above, and the torsion wind force is weakened. In addition, Tomi 1
A toumi wind force sensor S3 for detecting the toumi wind force from the number of rotations of 8 is provided.

As shown in FIGS. 4 and 8, two layer thickness sensors S5a and S5b respectively oscillate in order to detect the layer thickness of the leaked material (such as grains) on the chaff sheave 24. It is attached to a rod 40 provided on the upper side of the left and right side plates of the sorting plate 19, and is disposed on the front side and the rear side of the chaff sheave 24. Each of the layer thickness sensors S5a and S5b is a plate-like member T1 or T2 that is swingably hung around a horizontal axis.
And a potentiometer PM for converting the rotation angle of the plate-like members T1 and T2 to the rear (in the transport direction of the processed object) into a resistance value. When the layer thickness of the processed material is small, the plate-shaped member T
The plate-like member T2 is configured to contact the processing object and rotate rearward, and when the layer thickness increases, the plate member T2 contacts the processing object and rotates rearward.

According to the above configuration, since the rotation angle of the plate-like members T1 and T2 increases as the amount of the processing object increases and the layer thickness increases, the processing is performed based on the resistance value of the potentiometer PM (the voltage value corresponding to the resistance value). The layer thickness of the object, that is, the amount of the processed object can be detected. The first layer thickness sensor S5a on the front side is provided below the receiving net 22 so as to detect the thickness of the processed material leaking from the receiving net 22. At S5a, a processing amount detection unit that detects the amount of the processing object leaking from the handling room A is configured.
The second layer thickness sensor S5b on the rear side is a Glensheave 2
5 is provided corresponding to the rear end position, and the layer thickness of the grain detected by the second layer thickness sensor S5b is substantially zero, that is,
When only straw waste is present, it is determined that leakage at the chaff sheave 24 is proper.

As shown in FIG. 4, one end 34a of the swing link 34 is pivotally attached to the rear side of the swing sorting plate 19, while the other end 34b is pivotally attached to the fixed frame side, and the intermediate portion 34c is provided. Is pivotally attached to one end of a movable link 35a of the eccentric cam mechanism 35. In such a structure, when the eccentric cam mechanism 35 is rotated by driving the rocking motor M4 (see FIG. 1), the rocking link 34 rocks around the other end 34b as a fulcrum. 19 will rock.

On the other hand, bearings 36 are fixed to the left and right side plates on the front side of the swing sorting plate 19, and a pair of left and right U-shaped guides 37 slidably supporting the pair of left and right bearings 36 are fixed frames. It is provided on the side. As shown in FIG. 9, the guide 37 rotates around the horizontal axis Q via the gear box 38 and the sector gear 39 by rotating the angle changing motor M3 forward and backward. Thereby, the swing sorting plate 1
The sliding position of the bearing 36 at the time of swing of the 9 moves, and the inclination angle of the swing selection plate 19 changes. That is, U
If the posture of the character-shaped guide 37 is rotated to the vertical posture side from the posture of FIG. 9, the front side of the swing sorting plate 19 is raised, and the vertical stroke at the time of swing is increased, and the processing object feeding ability is high. However, if it is turned to the horizontal posture side, the swing sorting plate 19
, The vertical stroke at the time of swinging thereof is reduced, and the workpiece feeding capability is reduced. In addition, a potentiometer (hereinafter, referred to as a separation plate angle sensor) S4 for detecting the inclination angle of the swing selection plate 19 from the rotation angle of the sector gear 39 (guide 37) is provided.

As shown in FIG. 1, a control means H comprising a microcomputer or the like is provided.
Has the aforementioned threshing switch SW1, neutral switch SW
2. Each of the culm thickness sensor S1, the chaff opening sensor S2, the turf wind sensor S3, the sorting plate angle sensor S4, the first and second layer thickness sensors S5a and S5b, the stock sensor S6, and the engine speed sensor S7. Detection information has been entered. On the other hand, from the control means H, the aforementioned sheave motor M
1. Drive signals for the torsion motor M2, the angle changing motor M3, and the swing motor M4 are output.

The control means H includes a threshing switch SW
1 is on, that is, while the threshing apparatus 2 is operating, the leakage opening degree of the swing sorting plate 19 (actually, the chaff sheave 24) is handled based on the detection information of the first layer thickness sensor S5a. Changing the sheave motor M1 so that the target leak opening degree increases as the amount of the leaked material from the chamber A increases,
That is, it is configured to rotate in the forward and reverse rotation directions.
In addition, at this time, in accordance with the adjustment of the leak opening to the target leak opening, the target wind power becomes larger as the amount of the material to be leaked from the handling room A is larger, in accordance with the adjustment of the leak opening to the target leak opening. Thus, the torsion motor M2 is rotationally driven. In order to perform this control, the control means H obtains a target leak opening and a target toumi wind corresponding to the detection value of the layer thickness sensor S5a based on the stored relation table. The control is performed such that the deviation from the detection value of the chaff opening sensor S2 or the wind power sensor S3 is within an allowable range.

Further, the control means H complements the control of the leak opening based on the detection information of the first layer thickness sensor S5a to make the leak state of the processing object on the swing sorting plate 19 an appropriate state. The tilt angle of the swing sorting plate 19 is also controlled in order to maintain the tilt angle. That is, the control means H controls the second layer thickness sensor S5
On the basis of the information of b, when the state of leakage of the processed material in the rocking sorter plate 19 (chaff sheave 24) is a state of insufficient leakage, that is, the layer thickness detection value indicates that there is a grain layer other than straw waste. In such a state, the angle changing motor M3 is operated so that the tilt angle of the swinging selection plate 19 becomes large. As a result, the vertical stroke at the time of swinging of the swing sorting plate 19 is increased, and the leaking action on the processing object is promoted, and the layer thickness detection value of the second layer thickness sensor S5b indicates that only straw waste exists. Thus, the value of the appropriate leak state is obtained, and the insufficient leak state is eliminated.

Further, the control means H controls the state in which the amount of the processing object detected by the first layer thickness sensor S5a is equal to or less than a set amount and the leakage opening degree is adjusted to be small. The opening operation control for operating the sheave motor M1 such that the leak opening becomes a set leak opening larger than a target leak opening corresponding to the detected processed amount with a predetermined work condition. Configured to run.

Further, the control means H determines that the stock sensor S6 is switched from on to off (ie, the predetermined working condition).
After switching from the reaping operation state to the non-rearing operation state, the opening operation control is executed when the neutral switch SW2 is turned on (that is, the driving of the crawler traveling device 1 is stopped). ing.

Further, the control means H includes a stock sensor S6
Switches from on to off for a set time (for example,
After a lapse of one minute), the sheave motor M1 is operated so that the leak opening becomes the target leak opening.

Further, the control means H includes a stock sensor S6
Is switched from on to off, the toumi motor M2 is operated so that the toumi wind force becomes the set minimum value.

In addition, a chaff adjustment volume VR1 for finely adjusting the target leakage opening degree and a toumi adjustment volume for finely adjusting the target wind power according to conditions such as the degree of wetting of the crop to be harvested. VR2 is provided. Further, a chaff increase adjusting volume VR3 for adjusting the set leak opening in the opening operation control is provided. The setting information of each of the chaff adjustment volume VR1, the toughness adjustment volume VR2, and the chaff increase adjustment volume VR3 is input to the control means H.

Next, a method of obtaining the target leak opening will be described. First, based on FIG. 11A, a reference target value (T) based on the chaff adjustment volume VR1 is set. The reference target value (T) is obtained by adding a correction value (± 1 V) by the chaff adjustment volume VR1 to a predetermined standard setting value (2.5 V). Next, FIG.
A first correction value (L) based on the engine load is obtained based on (b). The load is obtained from the detection value of the engine speed sensor S7, and here, the load is the amount of decrease in the engine speed with respect to the engine speed (reference speed) when the vehicle speed is less than 0.1 m / s. Next, FIG.
Based on (c), a second correction value (C) based on the amount of the processed object detected by the first layer thickness sensor S5a is obtained. Eventually, a value obtained by adding the first and second correction values to the reference target value (T) (T + L + C) becomes the target leak opening. That is, the target leak opening is set by the voltage value.

The same applies to the method of obtaining the target wind power. Based on FIG. 12 (a), a reference target value (T) based on the torsion adjustment volume VR2 is set.
The first correction value (L) obtained based on (b) and FIG.
The value (T + L + C) obtained by adding the second correction value (C) obtained based on (c) is the target wind power.

As shown in FIGS. 11 (c) and 12 (c), the detection processing amount (detected by the voltage value) of the first layer thickness sensor S5a is increased in the direction in which it increases. The first, second, third, fourth and fifth stages (hereinafter referred to as sheave levels) are divided into two stages, and a second correction value (C) for obtaining a target leak opening degree and a target toumi wind force is: It is set corresponding to each sheave level.

For example, the first sheave level (1.5 V) is set as a set amount (set by a voltage value) of the detection processing amount of the first layer thickness sensor S5a for executing the opening operation control. It has been set. For example, a minimum reference target value (T) as a set minimum value for adjusting the wind power of the windmill as the stock sensor S6 switches from on to off.
A first correction value (L) corresponding to the minimum engine load (40 rpm or less), and a second correction value (L) corresponding to the first sheave level.
It is set to the target wind power calculated from the correction value (C). The set leak opening in the opening operation control is, for example, the chaff adjustment volume V being operated at that time.
The target leakage opening obtained from the reference target value (T) based on R1, the first correction value (L) based on the engine load at that time, and the second correction value (C) corresponding to the first sheave level is: It is set by adding an increase correction value (> 0) adjusted by the chaff increase adjustment volume VR3.

Next, the flow of the sorting control by the control means H will be described with reference to the flowchart shown in FIG. First, it is checked whether or not the threshing switch SW1 is on, and only when it is on, whether or not the stock sensor S6 is on. When the stock sensor S6 is on,
Based on the detection information of the first layer thickness sensor S5a, the leak opening is adjusted to the target leak opening, and the wind power is adjusted to the target wind power. When the stock sensor S6 switches from on to off, the toumi wind force is adjusted to the set minimum value and a timer is started. Then, a timer time (corresponding to the set time, for example, set to one minute) elapses (hereinafter referred to as time-up).
Until the neutral switch SW2 is turned off, the control state at that time (that is, the leak opening is the target leak opening and the storm wind force is the set minimum value) is maintained. If the detected processing amount in S5a is equal to or less than the set amount, the driving of the crawler traveling device 1 is stopped and the neutral switch SW2
Is turned on (that is, the predetermined working condition is reached), while maintaining the state of adjusting the storm wind force to the set minimum value, the leak opening is adjusted to the set leak opening. , The opening operation control is executed. If the stock sensor S6 is switched from off to on before the time is up, the leak opening is set to the target leak opening and the toumi wind force based on the detection information of the first layer thickness sensor S5a. To the target storm wind power respectively.

Subsequently, when the timer expires,
Based on the detection information of the first layer thickness sensor S5a, the leak opening is adjusted to the target leak opening, and the wind power is adjusted to the target wind power, and thereafter, the stock sensor S6 is turned on from off. Until it is changed, the state is continued, and when the stock sensor S6 switches from off to on, similarly, based on the detection information of the first layer thickness sensor S5a, the leak opening is set to the target leak opening, And, the wind power is adjusted to the target wind power respectively.

[Another Embodiment] Next, another embodiment will be described. (A) In the above embodiment, as a specific condition of the predetermined work condition, the neutral switch is set after the stock sensor S6 is switched from ON to OFF (that is, from the reaping work state to the non-rearing work state). Although the case where the SW2 is turned on (that is, the drive of the crawler traveling device 1 is stopped) is described as an example, various other conditions can be applied as specific conditions of the predetermined work condition. It is.
That is, for example, when the supply of the grain stalk to the handling room A is stopped, it is necessary to execute the opening operation control. Therefore, the predetermined work condition may be that a predetermined supply stop determination time elapses after the supply stop state of the grain stalk to the handling room A is detected. Although the supply of cereal stalks to the handling room A is continued, there is a case where the supply stop state is detected for a short time due to the variation of the supply state. Execution of the opening operation control can be avoided. In addition, the suspension state of the grain culm to the handling room A can be detected by, for example, the culm thickness sensor S1. Further, when the supply of the grain culm to the handling room A is stopped, the amount of the processed substance detected by the first layer thickness sensor 5a rapidly decreases from the large state and becomes equal to or less than the set amount. It may be applied as a condition.
In addition, when the above conditions are applied as specific conditions of the predetermined working conditions, the present invention may be applied to, for example, a stationary threshing apparatus in addition to the combine illustrated in the above embodiment. Can be.

(B) In the above embodiment, when the set operation time has elapsed after switching from the cutting operation state to the non-cutting operation state, when the opening operation control is being executed,
Although the case where the opening operation control is automatically canceled has been described as an example, a switch for manually canceling the opening operation control may be provided instead.

(C) In the above embodiment, the execution of the opening operation control is prohibited when the set time elapses after switching from the reaping operation state to the non-rearing operation state, even if the predetermined operation condition is reached. Although the case has been exemplified, the opening operation control may be executed at any time in the non-cutting operation state in accordance with the predetermined operation condition. In this case, when switching from the non-cutting operation state to the cutting operation state, the opening operation control may be automatically released, or the opening operation control may be manually released. A switch for performing the operation may be provided.

(D) In the above embodiment, the case where the chaff increase adjusting volume VR3 is provided so as to adjust the set leak opening in the opening operation control is exemplified. The chaff increase adjustment volume VR3 may be omitted, and the set leak opening may be fixed at a constant value. In this case, the configuration can be simplified.

(E) The set amount, the set minimum value, and the set time are not limited to the values exemplified in the above embodiment, but can be variously changed.

(F) The processing amount detecting means for detecting the amount of the processing material leaking from the handling room A is not limited to the first layer thickness sensor S5a of the above embodiment. For example, the processing object leaking from the handling room A onto the swinging sorting plate 19 is imaged by an imaging means such as a television camera, and the image information thereof is subjected to image processing to detect the amount of the processing object, or the transmission type light is used. It can be configured by various means such as projecting the detection light of the sensor to the processing object from the lateral direction and detecting the amount of the processing object from the state of the transmitted light.

(G) The means for causing the processed material to leak in the swinging sorting plate 19 while changing the degree of leak opening is not limited to the chaff sheave as in the above-described embodiment. For example, a net-like or slit-like opening may be used. The shield may be configured to be shielded by a shielding plate called a slide Glen pan, and the slide Glen pan may be slid to change the shielding area of the opening, that is, the opening degree.

The present invention is not limited to the self-removable combine as in the above embodiment, but can also be applied to a threshing device such as a harvester or the like, which is called a normal combine or a harvester.
