Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device such as a combine or a grain carrier.

[0002]

2. Description of the Related Art A conventional grain discharge device for a combine is shown in FIG.
), A bottom auger 10 is provided at the bottom of a Glen tank 9 for temporarily storing grains.
And a vertical auger 11 is provided.
And a laterally expandable and contractable dumping auger 12 is provided. Then, the auger auger 12 is extended in order to arrange the auger outlet 19 at a position where the aerial is to be hulled, and the auger auger 12 is shortened and stored when the hulling operation is not performed.

[0003]

In the dumping auger 12 of the combine 1 shown in FIG. 15, an upper tube 16 is fitted with a narrow gap to the outside of a middle tube 15 having a spiral 17 for carrying in. The upper tube 16 is configured to be freely slidably fitted in the tube 15 in the axial direction. Hereinafter, the middle tube 15 and the upper tube 16 are collectively referred to as a zoom cylinder.

[0004] The dumping auger 12 is made so as to be able to perform a so-called zoom action which can be extended and contracted by a zoom cylinder. When the threshing auger 12 is expanded and contracted, the volume of the threshing auger 12 in the zoom cylinder increases and decreases in proportion to the length of expansion and contraction, and therefore the amount of grains in the threshing auger 12 also increases and decreases. If it expands and contracts during operation, the amount of grains in the auger auger 12 increases and decreases while being hulled, so that no particular problem occurs. There is no special hindrance as long as there is a space in which no grains are present in 12.

However, if the auger auger 12 is stopped while the auger auger 12 is being shortened, or if the auger 12 is to be shortened while the auger auger 12 is stopped, the grain that is being transported in the zoom cylinder is transported. The auger 12 may not be able to shorten the auger auger 12, and the auger telescopic motor 50 (FIG. 1) and the spiral 17 may be damaged.

SUMMARY OF THE INVENTION An object of the present invention is to shorten a discharge device of particulate matter such as an auger auger which is in an extended state. An object of the present invention is to provide a retractable discharge device such as an augmenter for agitation, which does not cause breakage of the particulate matter discharge mechanism.

[0007]

The above object of the present invention is attained by the following constitution. That is, a driving means for discharging the grains and a discharge cylinder for discharging and guiding the grains by driving the driving means are provided, and a discharge port of the discharge cylinder moves in the longitudinal direction on the upper side and the lower side in the kernel discharging direction. When the discharge cylinder is configured as possible and the driving of the driving means is stopped during grain discharge,
This is a grain discharge device configured so that the discharge of the discharge tube does not move.

For example, a combine discharging auger will be described by way of example. In a combine having a helical conveying means for discharging grains and having an auger for discharging grains that is stretchable in the axial direction of the conveying means, A sensor means for detecting the degree of storage of the grain in the grain tank for grain storage, and a sensor means for detecting the operating state of the helical conveying means; , And the shortening operation of the axial expansion and contraction operation of the auger auger is invalidated on condition that there is a certain degree of movement and the stop of the driving of the conveying means.

In this manner, the sensor means capable of detecting the degree of storage of the grain in the tank when the grain is present in the Glen tank has the grain in the tank and the auger auger stops,
When the sensor means capable of detecting the operating state of the spiral conveying means detects that the auger has stopped driving, it operates so as to prohibit the shortening of the auger auger. Even if you stop the grain auger or perform an operation to shorten the auger auger while the auger auger is stopped, the shortening operation of the auger auger is invalidated and the shortening auger does not operate. It is possible to prevent damage caused by overload of the auger expansion / contraction drive device due to the clogging of the grain and the inability to shorten the augmentation auger, and damage to the spiral conveying means due to clogging of the grain.

FIG. 7 shows a shortened state of the upper tube 16 before zooming, and FIG. 8 shows an expanded state of the upper tube 16 after zooming is completed.

In the embodiment of the present invention, the Glen tank 9
It is characterized in that a grain reduction sensor 4 in the tank (FIG. 4) and a discharge clutch sensor 3a (FIG. 9) are provided on the discharge operation lever 3 in the lower part inside.

As shown in FIG. 9, the grain reduction sensor 4 in the tank can be mounted as long as it can detect that the grains in the Glen tank 9 are almost discharged and the Glen tank 9 is empty. The position and the type of the sensor are not limited. For example, a level sensor such as a photoelectric type, an ultrasonic type, an electrostatic type, or a piezoelectric type may be used.
There is no limitation on the mounting position and the type of the sensor as long as it can detect that the discharge operation lever 3 is "OFF".

That is, when the grain discharging auger 12 is operating with the clutch engaged, and when the grain reduction sensor 4 in the tank is OFF, that is, when there is no grain in the Glen tank 9 (in this case, the ON / OFF of the discharging clutch sensor 3a, ie, the clutch Cutting, entering, regardless of whether the auger auger 12 is stopped or in operation) acts to make the auger auger 12 extendable.

Table 1 summarizes the above.

[Table 1]

As described above, in the present invention, the middle tube 15
The upper tube 16 is fitted in the zoom cylinder to form a zoom cylinder.
In the grain discharging auger 12 capable of telescopic zooming, the grain tank reducing sensor 4 is provided at the lower portion inside the Glen tank 9 and the discharging operation lever 3 is provided with a discharging clutch sensor 3a. When the grain is present and the in-tank grain reduction sensor 4 is ON and the dumping auger 12 is stopped and the discharge clutch sensor 3a is ON, the shortening of the dumping auger 12 is prohibited. With this configuration, even if the auger auger 12 is stopped while the auger auger 12 is being shrunk, or the auger auger 12 is shortened while the auger auger 12 is stopped, the auger auger 12 is not affected.
Since the shortening operation is invalidated and the shortening operation is not performed, the grains during transportation in the zoom cylinder are clogged, the auger extension auger 12 cannot be shortened, and the auger expansion / contraction motor 50 is overloaded. 17 can be prevented. However, in the case where the above-mentioned shortening is impossible, the operation is performed when the discharge clutch is once turned on and then the discharge clutch is turned off. Otherwise, if the shortening cannot be performed at the initial stage, the discharge port of the dumping auger 12 will not move.

FIGS. 10 and 11 show modifications of the dumping auger 12 of the combine 1 of the embodiment shown in FIGS. 1 to 9 described above. FIG. 10 shows a dumping auger 12 and an auger receiver 40
FIG. 11 is a partially cutaway side view showing only the auger, and FIG. 11 is a view taken in the direction of arrows AA in FIG.

The dumping auger 12 that can be expanded and contracted in a zoom manner
Since the auger discharge port 19 can be moved to an arbitrary position, the work of carrying out the grain from the grain tank 9 of the combine 1 becomes extremely easy. If you forget, the auger auger 1
Since the tip of the combiner 2 projects beyond the tip of the weeding rod 7a (FIGS. 1 and 4), the traveling of the combine 1 may cause harm to the surroundings, and the combine 1 is discharged to the wall of the barn where the combine 1 is parked. There is a possibility that an accident or breakage may be caused, for example, the tip of the grain auger 12 may collide.

The waste auger 12 shown in FIGS. 10 and 11
Is in its shortened state, that is, the middle tube 15
5 shows a state in which the upper tube 16 fitted on the auger almost overlaps the middle tube 15, and the upper tube 16 of the dumping auger 12 is seated on the auger receiver 40.

The auger receiver 40 has a V-shaped bracket 42 fixed to the top of an auger support column 41 erected substantially at the center of the combine 1, and the dumping auger 12 is seated on the V-shaped bottom of the bracket 42. It has a configuration in which a limit switch 43 that sometimes operates as a contact is provided. Since the screw nut piece 53 meshing with the feed screw 52 of the auger extension mechanism 51 is fixed to the upper tube 16 of the auger 12 (FIGS. 2 and 3), the auger extension motor 50 is driven to rotate the feed screw 52. Then, the upper tube 16 and hence the dumping auger 12 expand and contract.

The expansion and contraction operation of the dumping auger 12 is normally performed by an operation switch (not shown) provided on the cockpit 2 or a hand-operated switch (not shown) provided at the tip of the dumping auger 12, but shown in FIGS. 10 and 11. In the example, even if the user has forgotten the shortening operation of the auger auger 12 at the end of the aerial work, if the auger auger 12 is stored in the auger receiver 40, the limit switch 43 is operated simultaneously with the seating of the auger auger 12. A control circuit that does not show details sends out a signal for shortening the auger auger 12 to drive the auger expansion / contraction motor 50 to automatically shorten the auger auger 12 and to show no details if the auger 12 is shortened to a predetermined shortest position. Since the shortening operation is stopped by the limit switch, the operation and the safety are useful.

The dumping auger 12 may be configured as shown in FIGS. FIG. 12 is a side view showing only the dumping auger 12 and the auger receiver 45,
13 is a cross-sectional view of the auger receiver 45 taken along the line BB of FIG. 12 (a cross section of the auger auger 12 is omitted). FIG. 14 is a side view of the auger receiver 45 taken along the line CC of FIG. FIG.

In FIGS. 12 and 13, the dumping auger 12 is in a shortened state, that is, in a state where the upper tube 16 fitted to the middle tube 15 is almost overlapped, and the upper tube 16 of the dumping auger 12 is in the auger receiver 45. Shows a state where the user is seated. In this case, the auger receiver 45 has a substantially V-shaped bracket 46 fixed to the top of the auger support column 41 erected substantially at the center of the combine 1, and the opening 4 is provided on both sides of the V-shaped bracket 46.
The opening 46a is provided with rollers 47, 47 which are parallel to the V-shaped both sides of the bracket 46 and whose center of rotation is in a direction tangential to the outer periphery of the auger 12. The roller 47 has shaft necks 47a, 47a at both ends, and is rotatably supported on bearings 48, 48 with respect to a bracket 46. The surfaces of the rollers 47, 47 are V
It is configured to slightly protrude from the inner surface of the letter-shaped bracket 47 and to come into rolling contact with the outer periphery of the dumping auger 12 seated on the auger receiver 45.

In this way, when the user has forgotten the shortening operation of the auger auger 12 and stores the auger auger 12 in the auger receiver 45 at the end of the aerial work, the auger auger 12 is moved to the auger receiver 4.
Even if the auger 12 is seated and the auger extension / retraction motor 50 is driven and the auger auger 12 is shortened, the auger auger 12 and the auger receiver 45 are in rolling contact via the rollers 47 and 47, so that the The weight of the auger 12 and the thrust load in the left and right direction are supported by the rollers 47 and 47, and the frictional force acts as rolling friction, so that the force becomes extremely small. Therefore, an excessive load and frictional force are applied to the auger auger 12 and the auger receiver 45. The auger extension / retraction motor 50 can be reduced, and the required power of the auger extension motor 50 can be reduced.
