Description

  The present invention relates to a combine technique, and more particularly to a technique for operating a discharge auger that discharges grains in a grain tank by wireless communication using a remote control device.

Conventionally, a combine is known in which grains after threshing are stored in a glen tank, and the stored grains are conveyed by a discharge auger that can be moved up and down and swiveled to be discharged to the outside from a discharge port at the tip. It has become. Among such combiners, there is a type in which the discharge auger is moved up and down and turned by remote control using a wireless communication device (remote controller) (see, for example, Patent Document 1).
In the technique disclosed in Patent Document 1, a switch for moving the discharge auger up and down and turning is provided in the remote control device.

JP 2007-185194 A

  The ascending / descending speed and the turning speed of the discharge auger differ depending on the situation during the grain discharging operation such as the moving distance of the discharge auger (discharge port). Specifically, when the distance to which the discharge auger is moved up and down or swiveled is short (the position of the discharge auger is finely adjusted), it is appropriate that the raising and lowering speed and the turning speed of the discharge auger are slow. . On the other hand, when the distance to which the discharge auger is moved up and down or swiveled is long, it is appropriate that the raising and lowering speed and the turning speed of the discharge auger are high. Even when the distance to which the discharge auger is moved up and down or swiveled is long, the lifting speed and the turning speed immediately after the start of the movement of the discharge auger are appropriate to be slow for convenience of operation.

  However, in the technique disclosed in Patent Document 1, since the lifting and lowering speed and the turning speed of the discharge auger are set to a constant speed, when operating the discharge auger with a remote control device, the operator can remove the grain from the discharge auger. It was not possible to move up and down at the lifting speed according to the situation at the time of the discharge work and to turn at the turning speed. Therefore, there is room for improvement in the operability of the remote control device that remotely controls the discharge auger.

  The present invention has been made in view of such current problems, and an object of the present invention is to provide a combine that can improve the operability of a remote control device that remotely controls a discharge auger.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

And a control unit that controls driving based on the control unit, wherein the control unit moves up and down and swivels the discharge auger until a preset time elapses from the start of operation of the operation unit. The actuators are controlled so that the speed becomes the first set speed, and after the set time has elapsed, Serial as lifting speed and the turning speed of the discharge auger is faster second set speed than the first set speed, and controls the respective actuators.

  According to a second aspect of the present invention, there is provided set time changing means for changing the set time.

  According to a third aspect of the invention, there is provided setting speed changing means for changing the first setting speed and the second setting speed.

  As effects of the present invention, the following effects can be obtained.

  In Claim 1, the operator who operates using a remote control device changes the raising / lowering speed and turning speed of a discharge auger in steps according to the operation time of an operation means, and starts operation of a discharge auger with an operation means. It is possible to move up and down or turn at high speed after the set time elapses immediately after the set time elapses. Therefore, when the operator slightly adjusts or finely adjusts the position of the discharge auger, the operation time of the operation means can be shortened. It can be easily moved to the place. On the other hand, when the position of the discharge auger is largely adjusted, the operation time of the operation means becomes relatively long, so that the discharge auger can be moved up and down or swiveled at high speed and quickly moved to a desired place. Become. Therefore, it is possible to improve the operability of the remote control device that remotely controls the discharge auger.

  In claim 2, the operator who operates using the remote control device sets the set time according to the situation at the time of grain discharge by the discharge auger, It is possible to easily move the discharge auger to a desired place by appropriately using the turning speed. Therefore, it is possible to improve the operability of the remote control device that remotely controls the discharge auger.

  In Claim 3, the operator who operates using a remote control device sets the raising / lowering speed and turning speed of a discharge auger according to the condition at the time of the grain discharge by a discharge auger by a speed setting change means, It is possible to easily move to a desired place at an appropriate lifting speed and turning speed. Therefore, it is possible to improve the operability of the remote control device that remotely controls the discharge auger.

  The cylinder front rotation button 70i and the cylinder rear rotation button 70j are for rotating the grain discharge cylinder 40 forward and backward, respectively. While the cylinder front rotation button 70i or the cylinder rear rotation button 70j is being pressed, the control means 60 drives the cylinder rotation actuator 41 based on the received operation signal. When the push operation of the cylinder front rotation button 70 i or the cylinder rear rotation button 70 j is released, the control means 60 stops the cylinder rotation actuator 41. As a result, when the cylinder front turning button 70i or the cylinder rear turning button 70j is pushed, the grain discharge cylinder 40 turns forward or backward in response to the pushing operation. When the push operation is not performed, it stops without rotating.

  The machine-side operation device 70 is an example of the machine-side operation device, and is not limited to this. Moreover, the various buttons of this machine side operation apparatus 70 are examples of an operation means, and are not limited to this.

  Next, the configuration of the remote control device 80 will be described with reference to FIGS. 5 and 7.

  The remote control device 80 is a member for operating the discharge auger 32 using wireless communication. The remote control device 80 is detachably supported by a support holder provided in the vicinity of the grain discharge port of the operation unit 9 and the discharge auger 32, and is configured to be carried by an operator. The remote operation device 80 includes various buttons as operation means related to the operation of the discharge auger 32, a transmission unit 81, and a power button (not shown).

  The transmitting unit 81 is connected to the various buttons, and while the various buttons are being pressed, wirelessly transmits an operation signal corresponding to the pressing operation to the control unit 60 (more specifically, the receiving unit 61 of the control unit 60). To send in.

  The various buttons include an automatic right set / return button (“set / return” display button) 80a, an auger clutch button (“clutch” display button) 80d, an auger lift button (“up” display button) 80e, an auger Down button ("down" display button) 80f, auger left turn button ("left" display button) 80g, auger right turn button ("right" display button) 80h, cylinder front turn button ("front shooter" "Display button) 80i and a cylinder rear turn button (" post-shooter "display button) 80j.

  The automatic right set / return button 80a automatically and alternately moves the lifting auger 32 to a predetermined position during use or a storage position when not in use (position placed on the auger rest 21). For turning). When the automatic right set / return button 80a is pushed in a state where the horizontal discharge auger (hereinafter simply referred to as the discharge auger 32) is placed on the auger rest 21, the control means 60 causes the turning actuator 35 and the lifting / lowering actuator to move up and down. The actuator 37 is driven based on the received operation signal. As a result, the discharge auger 32 moves up and down and turns and automatically moves to a predetermined position so that the grain discharge cylinder 40 (grain discharge port) is located on the right side of the machine body. When the grain discharge is finished and the automatic right set / return button 80a is pushed, the control means 60 drives the turning actuator 35 and the lifting actuator 37 based on the received operation signals. As a result, the discharge auger 32 moves up and down and pivots automatically to the storage position when not in use. As described above, the automatic right set / return button 80a has the function of two buttons, that is, the automatic right set button 70a and the automatic return button 70c in the apparatus-side operation device 70 with one button.

  The auger clutch button 80d is for turning the auger clutch 33 on and off. While the auger clutch button 80d is being pressed, the control means 60 turns the auger clutch 33 "ON". When the pushing operation of the auger clutch button 80d is released, the control means 60 turns off the auger clutch 33. As a result, the discharge auger 32 discharges the grain to the outside only when the auger clutch button 80d is pressed. However, when the horizontal discharge auger cylinder 36 is placed on the auger rest 21 or when the opening on the front end side of the grain discharge cylinder 40 is arranged in the horizontal direction, the auger clutch button 80d is Even if it is pushed, the control means 60 does not “turn on” the auger clutch 33. Thereby, the discharge | emission of the grain by erroneous operation can be prevented.

  The auger up button 80e and the auger down button 80f are for raising and lowering the discharge auger 32, respectively. While the auger up button 80e or the auger down button 80f is being pressed, the control means 60 drives the lifting actuator 37 based on the received operation signal. When the pushing operation of the auger up button 80e or the auger down button 80f is released, the control means 60 stops the lifting actuator 37. As a result, the discharge auger 32 moves up or down in response to the pushing operation of the auger raising button 80e or the auger lowering button 80f, and does not move up or down when the pushing auger 32 is not pushed. Stop.

  The auger left turn button 80g and the auger right turn button 80h are for turning the discharge auger 32 left and right, respectively. While the auger left turn button 80g or the auger right turn button 80h is being pressed, the control means 60 drives the turning actuator 35 based on the received operation signal. When the pushing operation of the auger left turning button 80g or the auger right turning button 80h is released, the control means 60 stops the turning actuator 35. As a result, when the auger left turn button 80g or the auger right turn button 80h is pushed, the discharge auger 32 turns left or right according to the push operation, and when it is not pushed. Stop without turning.

  The cylinder front rotation button 80i and the cylinder rear rotation button 80j are for rotating the grain discharge cylinder 40 forward and backward, respectively. While the cylinder front rotation button 80i or the cylinder rear rotation button 80j is being pressed, the control means 60 drives the cylinder rotation actuator 41 based on the received operation signal. When the push operation of the cylinder front rotation button 80i or the cylinder rear rotation button 80j is released, the control means 60 stops the cylinder rotation actuator 41. As a result, when the cylinder front turning button 80i or the cylinder rear turning button 80j is pushed, the grain discharge cylinder 40 turns forward or backward in response to the pushing operation. When the push operation is not performed, it stops without rotating.

  The remote operation device 80 is an example of a remote operation device, and is not limited to this. The various buttons of the remote operation device 80 are examples of operation means, and are not limited thereto.

  Next, the control at the time of operation of this machine side operation apparatus 70 and the remote operation apparatus 80 is demonstrated.

  The control means 60 drives and controls the lifting and lowering actuator 37 and the turning actuator 35 when each button for raising and lowering or turning the discharge auger 32 in the machine side operation device 70 and the remote operation device 80 is pushed. When raising / lowering or turning the discharge auger 32, the raising / lowering speed and the turning speed of the discharge auger 32 are changed according to predetermined conditions.

  In the present embodiment, the rotation speed of the electric motor is changed by changing the supply voltage to the electric motor constituting the turning actuator 35, and the turning speed of the discharge auger 32 is changed. By changing the amount of hydraulic oil supplied to the hydraulic cylinder constituting the lifting actuator 37, the expansion / contraction speed of the hydraulic cylinder is changed, and the raising / lowering speed of the discharge auger 32 is changed.

This will be specifically described below with reference to the flowchart of FIG.
In the following description, since the speed control by the operation of the main unit side operation device 70 and the remote operation device 80 is the same, only the operation of the remote operation device 80 will be described, and an auger up button 80e, an auger down button 80f, The pushing operation of the auger left turn button 80g or the auger right turn button 80h is referred to as “button operation”.

  First, in step 101, when a button operation is performed on the remote operation device 80, an operation signal is transmitted from the transmission unit 81 to the reception unit 61 of the control means 60 while the button operation continues. The control unit 60 inputs the signal received by the receiving unit 61 to the arithmetic processing device 62 of the control unit 60.

  In step 102, after resetting the timer T, the control means 60 starts time measurement from the start of button operation (from the time when the signal from the receiving unit 61 is input to the arithmetic processing unit 62) by this timer, Elapsed time T1 is obtained.

In step 103, the control means 60 drives the raising / lowering actuator 37 or the turning actuator 35 corresponding to the button operation so that the raising / lowering speed and the turning speed of the discharge auger 32 become the first set speed, and the discharge auger 32. Is raised or lowered.
Here, as shown in FIG. 9, the first set speed is gradually increased from 0 within a range slower than the normal lifting speed and turning speed of the discharge auger generally set in the conventional combine. It is preset to become (accelerate). However, it is also possible to set the first set speed so as to be a constant speed within the range.

In step 104, the control means 60 determines whether the elapsed time T1 measured by the timer T is within the set time T2 while the lifting actuator 37 or the turning actuator 35 is driven based on the button operation. To do.
Here, the set time T2 is set in advance and stored in the storage device 63 of the control means 60.

As a result, when the elapsed time T1 measured by the timer T is equal to or longer than the set time T2, that is, when the set time T2 has elapsed from the start of the button operation (the button is pressed and operated), the control means 60 The step moves to step 105.
On the other hand, if the elapsed time T1 measured by the timer T is within the set time T2, that is, if the set time T2 has not elapsed since the start of the button operation, the control means 60 shifts the step to step 108.

In step 105, as shown in FIG. 9, the control means 60 moves the lifting / lowering actuator 37 or the turning actuator 35 corresponding to the button operation so that the raising / lowering speed and turning speed of the discharge auger 32 are changed from the first set speed to the second. And the discharge auger 32 is moved up and down or turned.
Here, the second set speed is a constant speed that is faster than the first set speed, and is set in advance so as to be approximately the same as the conventional normal ascending / descending speed and turning speed.

  In step 106, the control means 60 determines whether or not the signal transmitted from the transmission unit 81 of the remote control device 80 is input to the arithmetic processing unit 62 via the reception unit 61, in other words, the start of button operation. It is determined whether or not the button operation is continued from the beginning.

As a result, when the signal from the remote operation device 80 is not input to the arithmetic processing device 62, that is, when the button operation is released, the control means 60 shifts the step to step 107.
When the signal from the remote operation device 80 is input to the arithmetic processing unit 62 of the control means 60, that is, when the button operation is continued, the control means 60 shifts the step to step 106. In this case, the control means 60 continues the movement of the discharge auger 32.

  In step 107, the control means 60 stops the turning actuator 35 or the raising / lowering actuator 37 corresponding to the button operation, and stops raising / lowering or turning of the discharge auger 32.

  In step 108, the control means 60 determines whether or not the signal transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing unit 62 via the reception unit 61, in other words, the button operation. It is determined whether or not the button operation has been continued from the start of.

As a result, when the signal from the remote operation device 80 is not input to the arithmetic processing device 62, that is, when the button operation is released, the control means 60 shifts the step to step 107.
When the signal from the remote control device 80 is input to the arithmetic processing unit 62 of the control means 60, that is, when the button operation is continued, the control means 60 shifts the step to step 104. In this case, the control means 60 continues the movement of the discharge auger 32.

  As mentioned above, the combine 1 which concerns on one Embodiment of this invention is the raising / lowering actuator 37 which raises / lowers the discharge auger 32 which can raise / lower and turn the discharge auger 32 which discharges | emits the grain in the Glen tank 17 outside. , A turning actuator 35 for turning the discharge auger 32, an elevating actuator 37, and an operating means for driving the turning actuator 35, and the actuators 35 and 37 are remotely operated by wireless operation using this operating means. A remote control device 80, and a control means 60 for driving and controlling the actuators 35 and 37 based on the operation of the remote control device 80. The control means 60 has a preset time set from the start of the operation of the operation means. Until the time T2 elapses, each actuator is set so that the raising / lowering speed and the turning speed of the discharge auger 32 become the first set speed. The actuators 35 and 37 are controlled, and after the set time T2, the actuators 35 and 37 are controlled so that the raising and lowering speed and the turning speed of the discharge auger 32 become the second set speed higher than the first set speed. To do.

  With such a configuration, an operator who operates using the remote control device 80 changes the lifting speed and the turning speed of the discharge auger 32 in a stepwise manner (in two steps) according to the operation time of the operation means. Ascending and descending at a high speed after the set time T2 (when the operation time of the operation means is long) after the set time T2 has elapsed (when the operation time of the operation means is short). Or it can be swung. Therefore, when the operator slightly adjusts or finely adjusts the position of the discharge auger 32 (when the movement distance of the discharge auger 32 is short), the operation time of the operation means can be shortened. The auger 32 can be moved up and down or swung at a low speed and easily moved to a desired location. On the other hand, when the position of the discharge auger 32 is greatly adjusted (when the movement distance of the discharge auger 32 is long), the operation time of the operation means becomes relatively long. Therefore, the discharge auger 32 is moved up and down or swung at high speed. It is possible to move quickly to a desired location. Therefore, the operability of the discharge auger 32 by the remote operation device 80 can be improved.

  Moreover, it becomes possible to change the raising / lowering speed and turning speed of the discharge auger 32 according to the operation time by one operation means. Therefore, for example, as compared with the case where two operating means for low speed and high speed are provided and the lifting speed and turning speed of the discharge auger 32 are changed, the operation speed of the discharging auger 32 is erroneously operated. There is no possibility of moving the discharge auger 32 by setting the turning speed to a high speed immediately after the start of operation of the operation means. Therefore, the discharge auger 32 can be operated without error by the remote control device 80, and the discharge auger 32 moves at a high speed immediately after the start of the operation of the operating means and comes into contact with the surroundings of the machine body, thereby being damaged. Can be prevented. In addition, an increase in the number of parts can be suppressed, and the remote control device 80 can be downsized.

  In addition, the stepwise change from the first set speed to the second set speed of the raising / lowering speed and the turning speed of the discharge auger 32 according to the operation time of the button operation on the remote control device 80 Since this is the same when a button operation on the operation device 70 is performed, the operability of the main unit side operation device 70 can be improved in the same manner as the remote operation device 80.

  In addition, although the raising / lowering speed and turning speed of the discharge auger 32 are changed in two stages in the present embodiment, three speeds are selected according to the operation time of the button pressing operation in the machine side operation device 70 and the remote operation device 80. You may make it change into a step or more.

  In addition, although the raising / lowering speed and turning speed of the discharge auger 32 are set to the same speed in this embodiment, it is also possible to set so that it may become a different speed. That is, the first set speed related to the lifting speed of the discharge auger 32 and the first set speed related to the turning speed are set to different speeds, and the second set speed related to the lifting speed and the second set speed related to the turning speed. It is also possible to set the set speed to a different speed.

  Note that the rotational speed of the discharge auger 32 in the front-rear direction of the grain discharge cylinder 40 is determined by the cylinder front rotation button 80i, the cylinder rear rotation button 80j of the remote operation device 80, and the cylinder of the machine side operation device 70. It is also possible to change in stages according to the operation time of the push operation of the front body rotation button 70i or the rear body rotation button 70j. This configuration is achieved by pressing the cylinder front rotation button 80i or the cylinder rear rotation button 80j of the remote operation device 80 and the cylinder front rotation button 70i or the cylinder rear rotation button 70j of the main unit side operation device 70. This is realized by measuring the elapsed time from the start of the operation and determining whether the elapsed time is equal to or longer than the set time.

Moreover, the combine 1 can be set as the structure provided with the setting time change means 91 which can change the setting time T2 memorize | stored in the memory | storage device 63 of the control means 60, as shown in FIG. The set time changing means 91 is arranged in the main unit side operation device 70, the remote operation device 80, or the operation unit 9, and is constituted by a rotary dial or a switch. The set time changing unit 91 is connected to the control unit 60. By operating the set time changing means 91, the set time T2 is arbitrarily changed by the control means 60 according to the operation.
The set time changing unit 91 is an example of a set time changing unit and is not limited to this.

  With such a configuration, an operator who operates using the remote operation device 80 or the main unit side operation device 70 sets the set time according to the situation at the time of grain discharge by the discharge auger 32, for example, the operation devices 70 and 80. The discharge auger 32 is set by appropriately using the lifting and lowering speed and the turning speed of the discharge auger 32 that change depending on the operation time of the operation means. Can be easily moved to other locations. Specifically, for example, if the operator is unfamiliar with the operation of the discharge auger 32 using the respective operation devices 70 and 80, if the set time T2 is set to a longer time, the raising / lowering speed of the discharge auger 32 and Since the time during which the turning speed is low continues for a long time from the start of the operation, the discharge auger 32 can be easily moved (lifted and turned) to a desired location. On the other hand, when the operator is accustomed to the operation of the discharge auger 32 using the operation devices 70 and 80, if the set time T2 is set to a shorter time, the lifting speed and the turning speed of the discharge auger 32 can be increased. The low-speed time ends in a short time from the start of the operation, the time during which the ascending / descending speed and the turning speed are high becomes relatively long, and the discharge auger 32 is easily and quickly moved to the desired place (elevating and turning) ). Therefore, it is possible to improve the operability of the remote operation device 80 that remotely operates the discharge auger 32. At the same time, the operability of the main unit side operation device 70 can be improved.

Further, as shown in FIG. 5, the combine 1 includes a set speed changing unit 92 that can set the first set speed and the second set speed stored in the storage device 63 of the control unit 60. It can be. The set speed changing means 92 is disposed in the main unit side operation device 70, the remote operation device 80, or the operation unit 9, and is configured by a rotary dial or a switch. The set speed changing unit 92 is connected to the control unit 60. By operating the set speed changing means 92, the operating speed of the turning actuator 35 or the raising / lowering actuator 37 is changed arbitrarily fast or slow according to the operation by the control means 60, and as a result, the raising / lowering speed and turning of the discharge auger 32 are changed. The speed is changed arbitrarily fast or slow.
The set speed changing means 92 is an example of the set speed changing means, and is not limited to this.

  With such a configuration, an operator who operates using the remote operation device 80 or the main unit side operation device 70 can set the lifting / lowering speed and the turning speed of the discharge auger 32 by the set speed changing means 92 when the grain is discharged by the discharge auger 32. Depending on the situation, for example, it is set according to the operating condition of each operation device 70, 80 and the positional relationship between the machine body and the grain discharge destination, and the discharge auger 32 is set at a desired location at an appropriate lifting speed and turning speed. It can be easily moved to. Specifically, for example, if the operator is unfamiliar with the operation of the discharge auger 32 using the respective operation devices 70 and 80, the discharge auger 32 can be moved by setting the raising / lowering speed and turning speed of the discharge auger 32 to be slow. Since it moves up and down and turns at a lower speed than the first set speed or the second set speed set last time, the discharge auger 32 can be easily moved (lifted and turned) to a desired place. On the other hand, when the operator is accustomed to the operation of the discharge auger 32 using the operation devices 70 and 80, the discharge auger 32 is set last time if the raising / lowering speed and the turning speed of the discharge auger 32 are set faster. Further, since the elevator auger 32 moves up and down faster than the first set speed or the second set speed, the discharge auger 32 can be easily and quickly moved (lifted and turned) to a desired place. Therefore, it is possible to improve the operability of the remote operation device 80 that remotely operates the discharge auger 32. At the same time, the operability of the main unit side operation device 70 can be improved.
