Description

  The present invention relates to a combine auger control device including an auger tip side switch disposed on a tip side of a discharge auger and an auger driver seat side switch provided on a driver seat side.

  Conventionally, a combine is provided with a discharge auger that carries grain stored temporarily in a grain tank out of the machine, and the discharge auger is swiveled or raised or lowered according to the operation of an auger operation switch. However, since it is necessary to accurately align the discharge port of the discharge auger during the transfer to the transport vehicle during the grain unloading operation, for example, the auger operation switch is set to 2 on the driver seat side and the auger tip side. It is provided at a location so that alignment can be performed easily and accurately. When a plurality of auger operation switches provided on the driver's seat side and the auger tip side are operated at the same time, the discharge auger is held in a stopped state to prevent the turning operation of the discharge auger based on an erroneous operation. I am doing so. Further, for example, an auger discharge switch related to grain discharge is also well-known that is separately disposed on the auger driver seat side and the auger tip side (see, for example, Patent Document 1).

JP 2000-4659 (3rd page, FIG. 5)

  In the above-described conventional example, there is no description about simultaneous operation of the auger discharge switch on the driver's seat side and the auger tip side regarding grain discharge. For example, after the auger discharge switch is set to “OFF”, the auger discharge switch is set to “ON”. It is known that the operation to be performed is regulated for a certain period of time. However, in this case, for example, the switch operation on the auger driver's seat side may be prioritized over the switch operation on the auger tip side where the discharge state can be confirmed. In addition, for example, if the discharge switch on the driver's seat side and the discharge switch on the auger tip side are not distinguished and a push button type momentary switch is used as the discharge switch, the discharge switch is temporarily set to “ON” on the auger tip side. If the operator tries to set the discharge switch to “ON” on the driver's side after the operation, the grain discharge will be stopped as a result, not only will the dead time be generated, but also the switch “ON” and “OFF” will be turned off. When the open (time) control is performed, the motor lock is generated unnecessarily, so that the internal breaker of the motor may be operated and may be disabled for a while.

  The present invention has been made to solve such a problem, and the object of the present invention is to allow the switch operation on the auger tip side to be prioritized over the switch operation on the auger driver's seat side with respect to soot discharge. It is to provide a combine auger control device.

In order to achieve the above object, the invention according to claim 1 includes a discharge auger (20) for discharging the grains temporarily stored in the grain tank (16) to the outside of the machine, and the discharge auger (20). An auger tip side switch (30) disposed on the tip side, an auger driver seat side switch (38) provided on the driver seat (14) side, and the auger tip side switch (30) or the auger driver seat side switch In a combine (10) comprising control means (40) for controlling the discharge auger (20) based on the operation of (38),
The control means (40) invalidates the operation command from the auger driver seat side switch (38) within a predetermined time after operating the auger tip side switch (30), and the auger tip side switch (30 ) Is provided with a priority processing unit (41) that prioritizes the operation.

  In addition, the code | symbol in the parenthesis mentioned above is shown in order to refer drawings, Comprising: This invention is not limited at all.

  According to the first aspect of the present invention, the operation command from the auger driver's seat side switch is invalidated and the operation of the auger tip side switch is prioritized within a certain time after the auger tip side switch is operated. Therefore, priority is given to the operation of the operator on the tip side of the auger that can confirm the grain discharge status, and the soot discharge can be performed accurately. Further, when there is no operator at the auger tip side, the operation by the auger driver side switch can be performed in real time, so that the discharge operation can be performed without any trouble.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a side view of a combine to which the present invention is applied. In FIG. 1, the combine 10 includes a traveling machine body 13 supported by left and right crawler traveling devices 12, 12. A driver's seat 14 and a grain tank 16 are arranged behind the driver's seat 14 on the left and right sides. Further, a threshing unit 17 is disposed on the left and right other sides of the traveling machine body 13, a post-processing unit 15 for processing the threshed waste straw is disposed on the rear part of the traveling machine body 13, and further, in front of the traveling machine body 13. The pre-processing unit 18 is supported so as to be movable up and down. In FIG. 1, one of the left and right crawler travel devices 12, 12 is not shown.

  The pretreatment unit 18 includes a divider 19 for weeding the cereal and the pulling device 11 and the culm harvested by the pretreatment unit 18 is taken over by a feed chain (not shown). Is supplied to the threshing unit 17 and further threshed and sorted in the threshing unit 17, and the selected grain is lifted and transferred and temporarily stored in the grain tank 16. The grains stored in the grain tank 16 are a fixed pipe 25 extending from the lower rear part of the grain tank 16 and a vertical pipe that is rotatable and substantially perpendicular to the fixed pipe 25. It is carried out of the machine via the pipe 26 and the discharge auger 20 connected to the upper end of the vertical pipe 26 so as to be integrally rotatable and undulating. The discharge auger 20 can be raised and lowered as the hydraulic cylinder 27 expands and contracts, and can be turned by driving an electric motor 28 that rotates the vertical pipe 26. The vertical pipe 26, the discharge auger 20, and the like are provided with a transfer spiral (not shown), and the transfer spiral is driven to rotate in response to an operation of engaging a discharge clutch (not shown).

  An engine room (not shown) is defined on the rear rear side of the driver's seat 14, and one side of the engine room is covered with an engine cover 21. The driver's seat 14 has a seat seat 22 on the center side, and on the operation panel 23 in front of the seat seat 22, a multi-steering lever 24 erected so as to be tilted and other operation levers (not shown). Etc.) are arranged.

  FIG. 2 shows a front end clutch switch (auger front end side switch) 30 disposed on the front end side of the discharge auger 20. The tip clutch switch 30 is a push button type momentary switch. When the tip clutch switch 30 is pushed, a built-in lamp (tip clutch switch lamp) 30a is turned on, and a clutch motor for discharging the grain (see FIG. 5). 42 is turned on so that the grain is discharged from the tip of the discharge auger 20 and can be visually confirmed. On the front side of the distal end of the discharge auger 20, a left-turn switch 31 that drives the electric motor 28 attached to the vertical pipe 26 to turn leftward by a push operation, and a right-hand turn that drives the electric motor 28 to turn rightward. A turn switch 32 is provided.

  FIG. 3 is an external perspective view of various switches relating to the discharge auger 20 disposed in the auger operation section 33 at the rear of the seat 22. The discharge auger 20 is manually raised and lowered in the auger operation section 33. An auger manual lever switch 34 to be moved, an auger automatic switch 36 to automatically move the discharge auger 20 to a predetermined discharge position or a storage position, an auger emergency stop switch 37 to stop the turning movement of the discharge auger 20, and a driver's seat A clutch switch (auger driver seat side switch) 38 is provided. The driver's seat clutch switch 38 is a push button type momentary switch. When the driver's seat clutch switch 38 is pressed, a built-in lamp (driver's seat clutch switch lamp) 38a is turned on, and a clutch motor for discharging a grain (see FIG. 5) 42 is turned on, and the grain is discharged from the tip of the discharge auger 20, and it can be visually confirmed that it is in that state.

  FIG. 4 shows a control block diagram of the present embodiment.

  In the figure, the control unit 40 is composed of a microcomputer and has a priority processing unit 41, and a driver's seat clutch switch 38 and a front end clutch switch 30 are connected to the input side of the control unit 40. On the output side, the grain discharge clutch motor 42, the driver's seat clutch switch lamp 38a that lights up when the driver's seat clutch switch 38 is pressed, and the tip clutch switch that lights up when the tip clutch switch 30 is pressed. A lamp 30a is connected. While the front clutch switch 30 is being pressed, a timer 43 is activated for a certain period of time. Even when the timer 43 is activated, even if the driver's seat clutch switch 38 is pressed, the operation command at this time is given to the priority processing unit 41. It is controlled to be invalid. That is, the priority processing unit 41 gives priority to the operation of the front end clutch switch 30 over the operation of the driver seat clutch switch 38.

  In the present embodiment, the case where the switch operation on the auger tip side can be prioritized over the switch operation on the auger driver's seat side has been described with respect to dredging, but the present invention is not limited thereto. The switch operation on the auger tip side may be prioritized over the switch operation on the auger driver seat side.

  FIG. 5 shows a flowchart relating to the discharge clutch control (discharge auger control) by the clutch motor 42 for discharging the grain.

  In FIG. 10, in S10, it is determined whether or not the front end clutch switch 30 has been operated from OFF to ON. If it has been operated from OFF to ON (Yes), it is determined in S11 whether or not the discharge flag is 0. If the discharge flag is 0 (Yes), the grain discharge clutch motor 42 is turned on in S12, the delay timer 43 is set, the discharge flag is set to 1, and the process returns to the first step. In S11, if the discharge flag is not 0 (No), the process proceeds to S13, where the grain discharge clutch motor 42 is turned off, the discharge flag is set to 0, and the process returns to the first step. Furthermore, if the front clutch switch 30 is not operated from OFF to ON in S10 (No), the process proceeds to S14, in which it is determined whether or not the driver's seat clutch switch 38 is operated from OFF to ON. If not (No), the process returns to the beginning. If operated (Yes), the process proceeds to S15. In S15, it is determined whether or not the delay timer 43 is 0. If the delay timer 43 is 0 (Yes), the process proceeds from S11 to S12, and the grain discharging clutch motor 42 is turned on in the same manner as described above. If the delay timer 43 is not 0 (No), the process returns to the first step.

  As described above, the operation command from the driver's seat clutch switch 38 is invalidated within a certain period of time after the tip clutch switch 30 is operated, and the operation of the tip clutch switch 30 is prioritized. Even in a situation where the voices of the operators cannot be heard due to a considerable amount of noise, the operator's operation at the tip side of the auger where the grain discharge status can be confirmed well is given priority, and an accurate soot discharging operation becomes possible. On the other hand, when there is no operator at the auger tip side, the driver's seat clutch switch 38 can be operated in real time, so that the dredging operation without any trouble can be performed.
