BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain carrying-out device in a combine, which is used for a self-removing type or a normal type combine.

[0002]

2. Description of the Related Art In a conventional combine harvester, when a grain tank is full and the grain is carried out to a truck waiting on the farm road, the combine harvester is first moved to the vicinity of the truck and then the grain carry-out ogre is used. It is configured to use-. In this case, the grain carrying-out auger drives the conveying spiral installed inside by aligning the tip discharge part with the tank of the truck (the loading platform, the same hereafter) while rotating in the vertical and horizontal directions. Then, the grains in the Glen tank are carried out to the tank of the truck.

In such a carrying-out operation, the combine may move due to the driving of the traveling device, and the tank of the truck and the leading end of the grain carrying-out auger are misaligned to transfer the grain. The action lacked certainty.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the deficiencies described in the above-mentioned conventional examples.
When the grain is transported from the Glen tank to the tank of the truck, the grain delivery auger causes a misalignment in the initially aligned relation between the chassis and the truck, impairing the certainty of grain delivery. It is to eliminate the points.

Normally, in a combine harvester, the traveling device is driven while the grain is being carried out in the conventional type, although it is required to surely stop the traveling device while the grain is being carried out. There was something. The present invention is intended to solve such a problem.

[0006]

The present invention takes the following technical means in order to solve the above problems. That is, a threshing device 3 and a grain tank 4 are mounted on a chassis 2 having a traveling device 1, and a grain carry-out auger 6 in which a grain transfer spiral 5 is installed is mounted on the grain tank 4 in a plane in the vertical direction. It is configured so that it can be rotated in the left-right direction inside, and a cutting pretreatment device 7 is provided at the front part of the chassis 2 so as to be vertically moved up and down, and the grain discharge auger 6 is in a stop position zone. Is a grain unloading device in a combine, which is provided with a control device 8 for automatically disabling the traveling device 1 when the traveling speed reaches.

[0007]

EXAMPLE First, the structure will be described. Chassis 2
The traveling device 1 has a crawler, and is configured to travel while maintaining subsidence in dry fields as well as wet fields. Then, the traveling device 1 includes a plurality of roller wheels 11 and adjustment wheels 1 bearing the front drive wheel 9 and the traveling frame 10.
It is wound around 2 and is composed.

As is conventionally known, the threshing device 3 has a sorting chamber below the handling chamber provided on the upper side, and the grain culm supply port 13 is located on the front side and mounted on the chassis 2. The grain tank 4 is arranged on the side of the threshing device 3 described above so as to store the fried grain after threshing and selection, and is mounted on the chassis 2. The grain tank 4 is configured so that an alarm buzzer alerts the operator when the supplied grain is full.

Next, the grain carrying-out auger 6 is provided with a vertical fried cylinder 14 whose lower end communicates with the bottom of the grain tank 4.
And a horizontal unloading tube 15 communicating with the upper end of the unloading tube 15, and a discharge port 16 is provided at the tip of the unloading tube 15. Further, the grain carrying-out auger 6 is configured so that the spur gear 17 attached to the lower portion of the fried grain cylinder 14 can be rotated by meshing with the adjusting gear 19 driven by the control motor 18.

The detection switch 20 has a structure capable of detecting the rotor 21 provided in the fried grain cylinder 14, and the rotor 21 is provided when the grain carrying-out auger 6 reaches the stop position zone. The detection switch 20 is arranged at a relevant position where it is pressed. Further, the grain carrying-out auger 6 is a hydraulic cylinder provided between the upper part of the lifting cylinder 14 and the base of the carrying-out cylinder 15.
It is configured such that it can be rotated in the vertical direction by 22.

Reference numeral 23 shows an operation lever of the grain carrying-out auger 6. The traveling mission device 24 is provided between the prime mover and the traveling device 1, and is composed of a side clutch device, a side brake device, a main transmission device, an auxiliary transmission device, and the like, as is conventionally known. Then, in this embodiment, the control device 8 which automatically disables the traveling is set to the controller-2 when the detection switch 20 is turned on as described above.
It operates in response to a signal from 7 to automatically operate the auxiliary transmission device to a stop position to stop traveling.

The structure for automatically stopping the traveling device 1 is as follows.
There is no particular limitation to the embodiment, and the main clutch may be disengaged to apply the brake. In short, when the grain carrying-out auger 6 enters the stop position zone, movement of the chassis is prevented. Any configuration may be used as long as it is stopped. Mowing pretreatment device 7
Is composed of a weeding rod 36, a grain culm raising device 37, a harvesting device 38, and a grain culm transporting device 39 from the front part, and is configured to be able to cut and transport grain culm in the field and supply it to the threshing device 3.

Another Embodiment Next, another embodiment will be described. Horizontal control device 2 for chassis 2
Reference numeral 5 denotes a device provided to correct the degree of inclination of the chassis 2 in the left-right direction, and these devices are equipped in most of the combine machines recently. This horizontal control device 25 operates automatically so that the grain carrying-out auger can be operated.
The operation occurs during the grain discharge work according to No. 6, and a failure occurs.

Therefore, first of all, the horizontal control device 25 is constructed so that the chassis 2 is equipped with an inclination sensor 26 to send a signal to the controller 27. And the traveling frame 10
Has an intermediate part pivotally attached to the fuselage and a hydraulic cylinder-2 at the other end.
8. Connect one end of the L-shaped operation link 29 connected to 8,
The front part is connected to the front part operation link 31 connected from the operation link 29 through the lot 30 so that the vertical height control can be performed separately on the right and left sides.

Therefore, the horizontal control device 25 has the chassis 2
The inclination sensor 26 detects the inclination of the
18 to the valve 32 from the controller 27.
The hydraulic cylinder 28 is expanded and contracted to adjust the left or right traveling frame 10 up or down to keep the chassis 2 horizontal. Reference numeral 33 indicates a stroke sensor.

The control switch 34 is a threshing operation lever 35.
It is configured so that it is turned on in association with the turning on operation and turned off in association with the turning operation. The horizontal control device 25 controls the controller 27 so that the control mechanism is turned off when the grain conveying auger 6 reaches the stop zone.
It is configured to be controlled in.

The operation of another embodiment configured as described above will be described. First, when the grain tank is full of grains, the operator is notified by an alarm and interrupts the cutting and threshing operations to prepare for grain discharge. The combine travels to the position of the truck, moves the grain carrying-out auger 6 and performs a moving operation so that the discharge port 16 at the tip is aligned with the tank of the truck. In this case, grain export ogre-6
Is moved upward by a hydraulic cylinder-22,
4 is driven from the control motor 18 through the adjusting gear 19 and the spur gear 17 to rotate in the left-right direction and move to a desired position.

In this way, the grain carrying-out auger-6 is
When the stop position zone is reached, the detection switch 20 detects the rotor 21 and sends a signal to the controller 27, and the above-mentioned horizontal control device 25 is turned off and does not work. Therefore, the grain carrying-out auger 6 can move the tip discharge port 16 until it fits in the tank of the truck, and the grain in the Glen tank 4 can be carried out and transferred to the truck in a combined state.

During such work, the grain carrying-out
Since the horizontal control device 25 is off in the motor 6,
The relative position between the chassis 2 and the truck does not change, and the grain can be reliably carried out. Conventionally, chassis 2
When the grain in the Glen tank 4 is carried out and the left and right weight balance is lost, the inclination degree changes accordingly, and the horizontal control device works to correct it, and the relationship between the tank of the truck and the discharge port 16 The position was out of order and there was no certainty in the work to carry out the grain.

Next, the operation will be described. First, an appropriate prime mover is started to start the mowing threshing work while driving the rotating parts of the machine body. Then, the grain culm in the field is mowed by the pre-mowing treatment device 7 and conveyed, and is transported to the threshing device 3
Is supplied to. Then, the grain culm is pinched by the feed chain of the threshing device 3 and conveyed while being fed from the grain culm supply port 13 to the handling chamber to undergo the threshing action, and further falls downward to undergo the sorting action. The grains thus threshed and sorted are discharged from the bottom of the threshing device to the outside of the machine and sequentially stored in the Glen tank 4 via the carrying device.

When the Glen tank 4 is continuously filled with work as described above and becomes full, an alarm is given to the operator. Next, in the work of carrying out the grains from the grain tank 4 to the outside of the machine, the chassis 2 is moved to a position close to the truck on the farm road, and the grain delivery auger 6 equipped in the grain tank 4 is moved in the direction of the truck. To move.

In this case, the grain carrying-out auger 6 is moved upward by the hydraulic cylinder 22 as in the case of the above-mentioned other embodiment, and the lifting cylinder 14 is adjusted from the control motor 18. It is driven via a gear 19 and a spur gear 17 to rotate in the left-right direction and move to a desired position. In this way, when the grain carry-out auger 6 reaches the stop position zone, the detection switch 20 detects the rotor 21 and the controller 27.
When the signal is sent to the control device 8, the control device 8 operates to operate the auxiliary transmission device to the stop position and stop the movement of the traveling device 1.

Then, the grain carrying-out auger 6 moves until its tip discharge port 16 faces the tank of the truck,
Although the unloading of the grain in the Glen tank 4 is started, the traveling device 1 is in a stopped state, and therefore the position is not misaligned and the grain can be reliably carried out.
