Description

  The present invention relates to a combine equipped with a first auger operating tool and a second auger operating tool for operating a grain discharging auger.

  A traveling machine body provided with a driver's seat, a grain discharging auger supported so as to be able to turn left and right and up and down with respect to the traveling machine body, a first auger operation tool provided on the driver's seat side, and other than the driver's seat A combine including a second auger operating tool provided so as to be operable from an operator at a place is conventionally known.

  The above combine has the advantage of being highly convenient because the auger can be operated (auger operation) from both the driver's seat and a place other than the driver's seat, while the auger operation by the first auger operation tool and the second auger operation tool. There is a problem that it sometimes conflicts with the auger operation.

In order to improve the above problems, the control unit is configured to give priority to one operation signal when different types of operation signals are simultaneously input from the first auger operation tool and the second auger operation tool. Combines 1 and 2 are known.
Japanese Patent No. 2666469 JP 2005-13161 A

In the combine described in the above document, when the control unit inputs an operation signal from one of the first auger operation tools and the predetermined auger operation tool to the control unit, the other auger operation is performed. Even if an operation signal from the tool is input to the control unit, the operation signal from the first auger operation tool is configured so as not to perform the auger drive control based on the operation signal from the other auger operation tool. And the operation signal from the second auger operating tool need to be identified, and the first auger operating tool and the second auger operating tool need to be individually connected to the input side of the control unit. This complicates the electrical connection between the control unit and the first auger operation tool and the second auger operation tool, and the processing performed by the control unit, leaving problems.
The present invention solves the above problems, and in a combiner configured so that the auger operation by the first auger operation tool and the auger operation by the second auger operation tool do not compete with each other, the control unit, the first auger operation tool, and the second auger operation tool. The purpose is to simplify the electrical connection with the operation tool and the processing procedure of the control unit.

  In order to solve the above-described problems, the combine of the present invention includes a traveling machine body 2 provided with a driver's seat 1 first, and a grain discharging auger 7 provided to be able to turn left and right and move up and down with respect to the traveling machine body 2. A first auger operating tool 18 that is provided on the driver's seat 1 side and performs a left / right turning operation and a raising / lowering operation of the auger 7, and a left / right turning operation of the auger 7 that can be operated from an operator other than the driver seat 1. And a second auger operating tool 22 that performs a lifting operation, and a control unit 24 that controls the driving of the auger 7 in response to an operation signal from the first auger operating tool 18 or the second auger operating tool 22. When the controller 24 is configured to give priority to one operation signal when different types of operation signals are simultaneously input from the first auger operation tool 18 and the second auger operation tool 22, the control unit 24 , 1st o Moth operation tool 18 and the different type of the operation signal from the second auger operating member 22 which is input, is characterized by controlling the driving of the auger on the basis of the operation signal input earlier.

  Secondly, the control unit 24 is the one in which one of the operation signals from the first auger operation tool 18 and the operation signal from the second auger operation tool 22 which has been input first and has priority is input. When another operation signal of the other type is input, the drive control of the auger 7 based on the other operation signal input later is not performed during the input of the one operation signal input earlier, and input later Even when one of the previously input operation signals is not input while the other operation signal is input, the drive control of the auger 7 based on the other operation signal input later is not performed. It is characterized by being composed.

  According to the combine of this invention comprised as mentioned above, in order to give priority to the operation of the side input previously among the 1st auger operation tool and the 2nd auger operation tool, input of the operation signal of a different kind. Since it is only necessary to detect the order, there is no need to connect the first auger operating tool and the second auger operating tool separately to the input side of the control unit, and the control unit, the first auger operating tool and the second auger operating tool, This makes it possible to simply configure the electrical connection and to simplify the processing performed by the control unit. In addition, since the operation on the side operated first is given priority, an auger operation unintended by the operator can be suppressed.

  In addition, the control unit is different while the one of the operation signals from the first auger operation tool and the operation signal from the second auger operation tool which has been input first and is given priority. When one type of operation signal is input, the auger drive control based on the other operation signal input later is not performed during the input of one operation signal input earlier, and the other operation signal input later Priority is given to the configuration in which the auger drive control based on the other operation signal that is input later is not performed even when the input of one operation signal that was input previously during the input is lost. Since the auger drive based on the auger operation on the side that has not been prioritized is not started immediately after the auger operation on the side that has been completed, the auger operation unintended by the operator can be more efficiently suppressed. That.

Hereinafter, the illustrated embodiment will be described.
FIG. 1 is an overall side view of a combine to which the present invention is applied. This combine mainly includes a traveling machine body 2 having a driver's seat 1 on the right side in the front traveling direction, a pair of left and right crawler traveling parts 3 and 3 that support the traveling machine body 2, and the front of the traveling machine body 2.

Is stored in a glen tank 6 provided in the vehicle, and waste or the like (such as potatoes) is discharged from the rear end of the traveling machine body 2 to the outside of the machine. The grain in the Glen tank 6 is discharged out of the machine via the auger 7.

  The auger 7 is mainly composed of a vertical cylinder 8 in the vertical direction and a discharge cylinder 9 extending linearly from the base end portion toward the tip end portion. The vertical cylinder 8 is supported on the right side of the rear end portion of the Glen tank 6 and is driven to turn left and right by an auger turning motor 11 (see FIG. 3) which is a turning actuator. On the other hand, the discharge cylinder 9 is supported at the upper end of the vertical cylinder 8 so that the base end thereof can swing up and down, and the hydraulic cylinder 12 that is a lifting actuator provided between the vertical cylinder 8 and the discharge cylinder 9 extends and contracts. Driven up and down by actuation. In addition, the grain conveyance of the auger 7 is performed by an auracene (not shown) that is rotationally driven in the vertical cylinder 8 and the discharge cylinder 9, and the grain in the glen tank 6 is discharged out of the machine from the tip of the auger 7. The

  2A is a perspective view of the first auger operating tool, and FIG. 2B is a front view of the second auger operating tool.

And a grain discharge switch 19 that rotates the augerase and discharges the grain through the auger 7.

  The first auger operating tool 18 is an operating lever for swinging back and forth and from side to side. The auger 7 is driven to swing upward (rising up) when the operator swings the operating lever 18 backward with respect to the advancing direction of the machine body, and the auger 7 is driven to swing downward (lowering) when operated forward. Then, the auger 7 is driven to turn left (left in the traveling direction, right in FIG. 2A) by swinging, and the auger 7 is driven to turn right by swinging right.

  An auger operation panel 21 is installed at the tip of the auger 7 (see FIG. 1). A second auger operation tool 22 (auger operation tool) is provided on the panel surface of the auger operation panel 21, and a grain discharge switch 23 having substantially the same configuration as the above-described grain discharge switch 19 is provided on the side. The second auger operating tool 22 is mainly composed of an auger raising switch 22a arranged on the upper side of the panel surface of the auger operating panel 21, an auger lowering switch 22b arranged on the lower side, and a left (advancing direction left, FIG. 2 (B), an auger left turn switch 22c disposed on the right side and an auger right turn switch 22d disposed on the right side.

  The second auger operating tool 22 pushes the auger ascent switch 22a (insertion operation) to drive the auger 7 to swing upward (raise), and pushes the auger lowering switch 22b (insertion operation) to operate the auger 7. Is driven to swing downward (down), the auger left turning switch 22c is pushed (input operation) to drive the auger 7 to turn left, and the auger right turn switch 22d is pushed (input operation) to move the auger. 7 is driven to turn right.

  Note that the second auger operation tool 22 may be provided in another place where it can be operated by an operator in a place other than the driver's seat 1 without being provided at the tip of the auger 7, or wirelessly capable of operating the auger 7 wirelessly. You may comprise by things like a machine (remote control).

  FIG. 3 is a block diagram showing the control structure of the combine. The combine is equipped with a control unit 24 (microcomputer) that controls the driving of the auger 7 in response to operation signals from the two auger operating tools 18 and 22. The control unit 24 is configured to drive the auger 7 to turn left and right or swing up and down (lift) in accordance with operation signals input from the first auger operating tool 18 and the second auger operating tool 22. Yes. Specifically, the above-described auger turning motor 11 and the auger raising valve 12a and auger lowering valve 12b, which are solenoid valves for extending and contracting the hydraulic cylinder 12, are connected to the output side of the control unit 24.

  On the other hand, on the input side of the control unit 24, an auger ascent switch 18 a that is turned on when the auger 7 of the first auger operating tool 18 is swung upward (lifted), and when the auger 7 is swung downward (lowered). An auger lowering switch 18b that is turned on, an auger left turning switch 18c that is turned on when the auger 7 is turned left, an auger right turning switch 18d that is turned on when the auger 7 is turned right, and a driver's seat 1 side grain discharge switch 19, auger raising switch 22a of second auger operation tool 22, auger lowering switch 22b, auger left turning switch 22c, auger right turning switch 22d, and auger 7 tip side grain A grain discharge switch 23 is connected.

  The auger ascent switch 18a of the first auger operating tool 18 and the auger ascent switch 22a of the second auger operating tool 22 are connected to the input side of the control unit 24 on the same line via a single ascending terminal 24a. The auger lowering switch 18b of the auger operating tool 18 and the auger lowering switch 22b of the second auger operating tool 22 are connected to the input side of the control unit 24 on the same line via a single lowering terminal 24b, and the first auger operation is performed. The auger left turning switch 18c of the tool 18 and the auger left turning switch 22c of the second auger operating tool 22 are connected to the input side of the control unit 24 on the same line via a single left turning terminal 24c, and the first auger The auger right turning switch 18d of the operating tool 18 and the auger right turning switch 22d of the second auger operating tool 22 are controlled on the same line via a single right turning terminal 24d. Other connected to the input side of the 4, also two grain discharge switches 19, 23 are connected to the input side of the control unit 24 in the same line through the single discharge terminal 24e.

  The four terminals 24a, 24b, 24c, and 24d for auger operation are pulled up (boosted) by a pull-up resistor (not shown) and are in a stable state. The eight switches 18a, 18b, When 18c, 18d, 22a, 22b, 22c, and 22d are turned on, the corresponding terminals 24a, 24b, 24c, and 24d are electrically grounded, and the control unit 24 detects the input of the operation signal. Yes. The discharge terminal 24e is also configured substantially the same as the other terminals 24a, 24b, 24c, and 24d.

  FIG. 4 is a processing flowchart of the control unit. When the drive control of the auger 7 by the control unit 24 is started, the process is started from step S1. In step S1, all the switches 18a, 18b, 18c, 18d, 22a, 22b, 22c, and 22d for the auger operation are not turned on (all terminals 24a, 24b, 24c, and 24d are not electrically connected). It is detected whether or not it is in a grounded state. If not all are in the input operation, the process proceeds to step S2, and if not, the process proceeds to step S3.

  In step S2, the edge flag data is reset, and the process proceeds to step S12. The edge flange data is composed of 4-bit data developed on the memory of the control unit 24. When the 0th bit of the edge flag data is “1”, it means that the upward swing operation of the auger 7 was performed in the previous processing loop of the processing flow in FIG. 7 means that the upward swing operation is not performed in the previous processing loop of the processing flow in FIG.

  When the first bit of the edge flag data is “1”, it means that the downward swing operation of the auger 7 was performed in the previous processing loop of the processing flow in FIG. 7 means that the downward swing operation of 7 was not performed in the previous processing loop of the processing flow in FIG.

  When the second bit of the edge flag data is “1”, it means that the left turn operation of the auger 7 was performed in the previous processing loop of the processing flow in FIG. 4, and when it is “0”, the auger 7 This means that the left-turning operation is not performed in the previous processing loop of the processing flow in FIG.

  When the third bit of the edge flag data is “1”, it means that the right turning operation of the auger 7 was performed in the previous processing loop of the processing flow in FIG. 4, and when it is “0”, the auger 7 This means that the right turn operation No. 7 has not been performed in the previous processing loop of the processing flow in FIG. When the edge flag data is reset, the value of each bit is set to “0” (the 0th bit, the first bit, the second bit, and the third bit are all “0”). In the initial state, the edge flag data is in a reset state.

  On the other hand, ON / OFF of all the switches 18a, 18b, 18c, 18d, 22a, 22b, 22c, and 22d is recorded in real time in input data composed of 4-bit data developed on the memory of the control unit 24. When the 0th bit of the input data is “1”, it means that the upward swing operation of the auger 7 is currently detected (the grounding state of the ascending terminal 24a is detected). This means that the upward swing operation of the auger 7 is not detected at present.

  When the first bit of the input data is “1”, it means that the downward swing operation of the auger 7 is currently detected (the grounding state of the descending terminal 24b is detected), and when it is “0” This means that the downward swing operation of the auger 7 is not detected at present.

  When the second bit of the input data is “1”, it means that the left turning operation of the auger 7 is currently detected (the grounding state of the left turning terminal 24c is detected), and when it is “0” This means that the left turning operation of the auger 7 is not currently detected.

  When the third bit of the input data is “1”, it means that the right turning operation of the auger 7 is currently detected (the grounding state of the right turning terminal 24d is detected). Means that the right turning operation of the auger 7 is not detected at present.

  In step S3, it is detected whether or not an auger operation has been performed in the previous processing loop with reference to the edge flag data, and is not performed (a state in which all bits of the edge flag data are “0”). ), The process proceeds to step S4, and if it is being performed, the process proceeds to step S12. In step S4, the value of the 0th bit of the input data is referred. If “1”, the process proceeds to step S5, and if “0”, the process proceeds to step S6. In step S5, the 0th bit of the edge flag is set to “1”, and the process proceeds to step 12.

  In step S6, the value of the first bit of the input data is referred. If “1”, the process proceeds to step S7, and if “0”, the process proceeds to step S8. In step S7, the first bit of the edge flag data is set to “1”, and the process proceeds to step S12. In step S8, the value of the second bit of the input data is referred. If “1”, the process proceeds to step S9, and if “0”, the process proceeds to step S10. In step S9, the second bit of the edge flag data is set to “1”, and the process proceeds to step S12. In step S10, the value of the third bit of the input data is referred. If “1”, the process proceeds to step S11, and if “0”, the process proceeds to step S12. In step S11, 3 bits of the edge flag data are set to “1”, and the process proceeds to step S12.

  In step S12, the input data and edge flag data are compared, and the process proceeds to step S13. In step S13, if it is detected by the comparison process in step S12 that the value of the 0th bit of the input data and the value of the 0th bit of the edge flag are both “1”, the process proceeds to step S14, and both “1”. If it is not detected, the process proceeds to step S15. In step S14, the auger 7 is driven to swing upward, and the process returns to step S1.

  In step S15, when it is detected by the comparison process in step S12 that the value of the first bit of the input data and the value of the first bit of the edge flag are both “1”, the process proceeds to step S16, and both are “1”. If it is not detected, the process proceeds to step S17. In step S16, the auger 7 is driven to swing downward, and the process returns to step S1.

  In step S17, when it is detected by the comparison process in step S12 that the value of the second bit of the input data and the value of the second bit of the edge flag are both “1”, the process proceeds to step S18, and both “1”. If it is not detected, the process proceeds to step S19. In step S18, the auger 7 is driven to turn left, and the process returns to step S1.

  In step S19, when it is detected by the comparison process in step S12 that the value of the third bit of the input data and the value of the third bit of the edge flag are both “1”, the process proceeds to step S20, and both are “1”. If it is not detected, the process proceeds to step S21. In step S20, the auger 7 is driven to turn right, and the process returns to step S1. In step S21, the auger 7 is stopped and the process returns to step S1.

  According to the combine configured as described above, when an auger operation is performed using one of the two auger operating tools 18 and 22 from a state where the auger 7 is stopped (initial state), step S1 → The process proceeds from step S3 to step S4, and the corresponding bit of the edge flag data is set to “1” by the process of steps S4 to S11, and the process proceeds to step S12. If an auger operation is performed in which the corresponding bit of the input data is “1” with reference to the edge flag data by the processing of step S12 to step S21, the drive control of the auger 7 based on the auger operation is performed. Is executed.

  For example, when the first auger operating tool 18 performs a downward swinging operation of the auger 7 with the first bit of the edge flag data set to “1”, step S12 → step S13 → step S15 → step The process proceeds to S16, and the auger 7 is driven to swing downward in Step S16.

  Once any bit of the edge flag data is set to “1”, an auger operation not corresponding to the edge flag data setting is performed in the subsequent processing of the processing flow shown in FIG. The drive control of the auger 7 based on the auger operation is not executed by the processing of step S13, step S15, step S17 or step S19.

  For example, as in the above example, the auger 7 is first swung downward by the first auger operating tool 18, the first bit of the input data is set to "1", and the auger 7 is driven to swing downward. In this state, even when the second auger operation tool 22 is used to swing the auger 7 upward and the 0th bit of the input data is set to “1” (the first auger operation tool 18 and the second auger operation Even if a different type of operation signal is input from the tool 22), since the 0th bit of the edge flag data is “0” in step S 13, the process does not proceed to step S 14, and the auger 7 swings upward. It is not driven dynamically.

  That is, when different types of operation signals are input from the first auger operation tool 18 and the second auger operation tool 22, the operation signal input first is prioritized and is based on the operation signal input first. Then, the drive control of the auger 7 is performed.

  Then, the auger operation is not performed from either the first auger operation tool 18 or the second auger operation tool 2, and all the switches 18a, 18b, 18c, 18d, 22a, 22b, 22c, 22d for the auger operation are When the input operation is not performed, the processing proceeds from step S1 to step S2 in the subsequent processing of the processing flow shown in FIG. 4, the edge flag data is reset, and the priority state is released.

  Due to such priority cancellation conditions, one of the operation signals from the first auger operation tool 18 and the operation signal from the second auger operation tool 22 that has been input first and that is prioritized is being input. When another operation signal of the other type is input to the other, the input signal of the auger 7 based on the other operation signal is input even if the other operation signal input later is input during the input of the one operation signal input earlier. In addition to the fact that drive control is not performed, if the input of the other operation signal that was input later continues even if the input of one operation signal that was input earlier from this state is lost Since the process does not proceed from step S1 to step S2 and the priority state is not released, the drive control of the auger 7 based on the other operation signal input later is not continuously performed.

  For example, as shown in FIG. 5, the auger 7 is first turned right by the first auger operating tool 18, and then the second auger operating tool is operated during the right turning of the auger 7 by the first auger operating tool 18. 22, the auger 7 is swung upward, and then the auger 7 is swung right by the first auger manipulator 18 while the auger 7 is swung upward by the second auger manipulator 22. When the second auger operation tool 22 is stopped and then the swinging operation of the auger 7 is stopped, the operation signal input to the other end (the right rotation of the auger 7 input from the first auger operation tool 18) is stopped. Step S1 → Step S3 while the operation signal input after the other (the upward swing operation signal of the auger 7 input from the second auger operating tool 22) is input together. → Step S12 → S Step S13 → Step S15 → Step S17 → Step S19 → Step S20 → Step S1 →... Is repeated, and the auger is driven and controlled based on the previously input operation signal (right turn drive control). Is done.

  Then, when the input of the operation signal input earlier is stopped and only the operation signal input later is input, the operation signal input thereafter is input earlier. Since the operation signal is input while the operation signal is being input, the priority state is not released, and step S1, step S3, step S12, step S13, step S15, step S17, step S19, step S21, and step S1. The process of... Is repeated, and the auger drive control (upward swing drive control) based on the subsequent input operation signal is not executed.

  Subsequently, when the input of the operation signal input later is stopped, the process proceeds from step S1 to step S2, and the priority state is released. Therefore, the first auger operation tool 18 or second input next is input. Based on the operation signal from the auger operating tool 22, the drive control of the auger 7 is performed.
