BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine auger automatic storage control device.

[0002]

2. Description of the Related Art Many combiners, especially large combiners, are provided with a spiral auger (grain discharge cylinder) for discharging grain, which is mounted on a traveling machine body so as to be able to rotate up and down and turn freely. During harvesting, when the grain tank is full of paddy during the harvesting operation, the harvesting operation is temporarily stopped, the combine is moved to the vicinity of a truck or other waiting truck on an agricultural road, etc. After raising the auger stored in the state to a predetermined angle (for example, 45 degrees), the auger is turned to the side of the fuselage, and the gutter at the tip of the auger is further lowered to just above the carrier of the carrier, and the auger in the grain tank is lowered. The grains are directly discharged and transferred to trucks and other transport vehicles without bagging.

[0003] When the operation of discharging the grain is completed, the auger is operated in the reverse order of the above operation to return to the storage position, and the mowing operation is restarted. There has also been proposed an apparatus (auto-return device) in which a series of related operations of raising, turning, and descending to a storage position of an auger can be automatically controlled by a button operation.

[0004]

However, the above-mentioned conventional auto return device is equipped with an upper limit switch which senses when the auger has risen to the upper limit in order to stop the auger when the auger has risen to the maximum. Not only is it necessary to increase the cost, but also because the auto return does not operate when the auger is set at a lower angle than the preset elevation angle (before the upper limit switch detects), there is an obstacle above the machine In such a case, the auto return cannot be used.

[0005]

SUMMARY OF THE INVENTION A combine auger automatic storage control device according to the present invention has been devised in order to solve the problem based on the above-described actual situation, and has a structure in which a grain discharger is mounted on a traveling machine. An automatic augment switch mounted on the traveling machine body and connected to a drive source of the auger for vertical agitation and rotation via a control unit. When the auger rises while the ON state continues, when the automatic return switch is switched from the ON state to OFF, the auger stops rising and turns to the storage position, then descends and automatically moves to the predetermined storage position. The gist is that it is configured to return to

[0006]

When the automatic return switch is operated from the OFF state to the ON state after the completion of the grain discharging operation, the automatic return (auto return) of the auger starts. If the auto-return switch is kept ON, the auger will continue to rise, but if the auto-return switch is turned off, the auger will stop rising at that point, turn from the outside of the fuselage to the upper storage position, and then descend. Automatically stored in the storage position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described with reference to an embodiment shown in the drawings. A is a combine, and a driver's seat 3 is provided on one front side of a traveling body 2 having a crawler 1.
An engine 4 is provided below the hopper, and a grain tank 5 is provided at the rear. A threshing unit 6 is provided beside the grain tank 5.
However, behind the threshing unit 6, there are provided cutters 7 for shredding the waste, respectively. A pre-processing unit 8 is mounted in front of the traveling machine body 2 so as to be able to move up and down.

9 is an auger for grain discharge (grain discharge cylinder)
In addition, it is mounted on the upper end of a fixed cylinder 10 erected on one side of the rear part of the traveling machine body 2 (the grain tank 5 side) so as to be vertically rotatable and pivotable. 11 is a hydraulic cylinder for auger vertical rotation, 12
Is a turning motor.

Reference numeral 13 denotes a fixed lever that locks the auger 9 in the retracted position. Reference numeral 14 denotes a grain discharge lever. When the grain discharge lever 14 is operated to the “enter” side, the grains in the grain tank 5 are moved by the auger 9. It can discharge automatically.

Reference numeral 15 denotes an auger manual operation lever switch.
After releasing the fixed lever 13, the auger 9 is raised,
The lowering operation, turning to the storage side, and turning to the discharge side can be performed by manual operation of the lever switch 15. Reference numeral 16 denotes a storage limit switch, and 17 denotes a discharge limit switch. These switches 15, 16, and 17 are connected to the input side of a control unit 18 composed of a microcomputer, and the auger 9 is connected to the output side of the control unit 18. Turning motor 12 and auger vertical turning hydraulic cylinder 1
The first solenoid valve 19 for raising and the solenoid valve 20 for lowering are connected.

Reference numeral 21 denotes an automatic return switch (auto return switch) for the auger 9 which is provided separately from the auger manual operation lever switch 15. The switch 21 is arranged in parallel with the switches 15, 16, 17 on the input side of the control unit 18. It is connected. The automatic return switch 21 is a momentary push button switch. When the push button is pressed once, the switch 21 is kept on until released, and when the hand is released from the push button, the switch 21 is turned off. . By the way, the auger 9 continues to rise while the automatic return switch 21 continues to be in the ON state, and when the automatic return switch 21 is switched from the ON state to the OFF state, that is, when the hand is released from the push button of the switch 21, At that time, the auger 9 stops rising and the turning motor 1
When the auger 9 is turned to the storage side by starting the auger 9 and the auger 9 is turned above the storage position, the storage limit switch 1 is turned on.
Since the switch 6 is turned on, the control circuit is configured so that the auger 9 descends and automatically returns to the predetermined storage position.

An auto return lamp 22 is connected to the output side of the control section 18. The auto return lamp 22 is turned on while the auger 9 is in the automatic return operation. Thereby, the operator can not only visually recognize that the auger 9 is performing the automatic return operation at the driver's seat position, but also operate the automatic return switch 21 even when the auger 9 does not perform the automatic return operation. It is possible to check whether the automatic return switch 21 is out of order or not. In the embodiment, the push button of the automatic return switch 21 is illuminated, and the push button is also used as the auto return lamp 22.

By the way, when the auger 9 is configured to immediately start turning toward the retracted side when the hand is released from the automatic return switch 21, if the switch 21 is pressed only for a very short time due to an erroneous operation or the like, the auger 9 is turned off. There is a risk that the auger 9 will start to turn while almost not climbing up, and the auger 9 will contact a part of the fuselage and damage the fuselage. In order to solve such inconveniences, as shown in FIG. 6, in the automatic return control circuit of the auger 9, a raising timer 23 is provided, and the time during which the automatic return switch 21 is pressed is shorter than the set time. In this case, the automatic return operation of the auger 9 is immediately stopped. That is, the automatic return switch 21 changes from OFF to ON, and the augment timer 23 is set at the same time when the auger 9 starts automatic return. If the raising timer is counting up when the automatic recovery switch 21 is turned off from the ON state, the automatic recovery operation is continued. However, if the raising timer 23 is not counting up, the automatic recovery of the auger 9 is performed. The operation is stopped. Reference numeral 24 denotes a lowering timer.

In the above configuration, after the discharge operation from the grain tank 5 is completed, when the push button of the automatic return switch 21 is pressed, the automatic return switch 21 is turned off from the OFF state to O.
N, automatic return operation of auger 9 (auto return)
Starts. If the push button is kept pressed, the automatic return switch 21 keeps the ON state and the auger 9 continues to rise. However, when the hand is released from the push button, the automatic return switch 21 is turned off and the auger 9 rises at that time. And start turning from the outside to the inside. Then, when the auger 9 turns to the upper position of the storage position, the storage limit switch 16 is turned on, and the auger 9 starts to descend at that time and is automatically stored in the storage position. After the storage, the auger 9 is locked in the storage position by operating the fixing lever 13, and the mowing operation is restarted.
