It is configured to turn left or right.

  Specifically, the control means 60 received while the auger ascending button 70e, which is the raising / lowering operation means of the discharge auger 32, and the auger left turning button 70g, which is the turning operation means, are simultaneously pressed. The turning actuator 35 is driven while the lifting actuator 37 is driven based on the operation signal. As a result, when the auger ascending button 70e and the auger left turning button 70g are simultaneously pressed, the discharge auger 32 turns left while ascending in accordance with the pressing operation, that is, diagonally upward to the left. When it is moving toward and is not pushed, it stops without moving.

  While the auger ascending button 70e, which is the raising / lowering operation means of the discharge auger 32, and the auger right turning button 70h, which is the turning operation means, are simultaneously pressed, the control means 60 is based on the received operation signal. Then, the turning actuator 35 is driven while the lifting actuator 37 is driven. As a result, when the auger ascending button 70e and the auger right turning button 70h are simultaneously pressed, the discharge auger 32 turns right while ascending in response to the pressing operation, that is, diagonally upward to the right. When moving in the direction and not being pushed, it stops without moving.

  While the auger lowering button 70f, which is the raising / lowering operation means of the discharge auger 32, and the auger left turning button 70g, which is the turning operation means, are simultaneously pressed, the control means 60 is based on the received operation signal. While driving the elevating actuator 37, the turning actuator 35 is driven. As a result, when the auger lowering button 70f and the auger left turning button 70g are pressed simultaneously, the discharge auger 32 turns left while descending in response to the pressing operation, that is, diagonally downward to the left. When it is moving toward and is not pushed, it stops without moving.

  While the auger lowering button 70f, which is the raising / lowering operating means of the discharge auger 32, and the auger right turning button 70h, which is the turning operating means, are simultaneously pressed, the control means 60 is based on the received operation signal. Then, the turning actuator 35 is driven while the lifting actuator 37 is driven. As a result, when the auger lowering button 70f and the auger right turning button 70h are simultaneously pressed, the discharge auger 32 turns right while descending in response to the pressing operation, that is, diagonally lower right. When moving in the direction and not being pushed, it stops without moving.

  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.
In the present embodiment, the auger raising button 80e and the auger lowering button 80f are examples of operating means for raising and lowering the discharge auger 32, and are not limited thereto.

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.
In this embodiment, the auger left turning button 80g and the auger right turning button 80h are examples of the turning operation means of the discharge auger 32, and are not limited thereto.

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.
In addition, in this embodiment, the cylinder front rotation button 80i and the cylinder rear rotation button 80j are an example of the operation means for rotation of the grain discharge cylinder 40 of the discharge auger 32, and are not limited thereto. .

Next, the arrangement of various buttons in the remote operation device 80 will be described with reference to FIG.
The remote control device 80 is configured to have a size that allows an operator using the remote control device 80 to hold it with one hand. In the remote control device 80, the various buttons are arranged on the same surface. When viewed from the operator using the remote operation device 80, the auger raising button 80e and the auger lowering button 80f, which are raising and lowering operating means of the discharge auger 32, are arranged so as to be positioned at the top and bottom of the rhombus, respectively. The auger left turn button 80g and the auger right turn button 80h, which are turning means for turning the discharge auger 32, are arranged on the left or right side in the vicinity of the auger up button 80e and auger down button 80f, respectively. It is arranged to be located at the left and right vertices. Further, the cylinder front rotation button 80i and the cylinder rear rotation button 80j, which are the operation means for rotating the grain discharge cylinder 40 of the discharge auger 32, are respectively the buttons of the lifting operation means and the turning operation means. Among them, the auger lowering button 80f disposed at the lowermost part is located on the left or right side thereof, the cylinder front turning button 80i is located below the auger left turning button 80g, and the cylinder rear turning button 80j is provided. It is arranged so as to be located below the auger right turn button 80h. The auger clutch button 80d is disposed so as to be positioned in the vicinity of the cylinder front rotation button 80i. The automatic right set / return button 80a is disposed so as to be positioned below and in the vicinity of the cylinder rear turn button 80j.
With such a configuration, as will be described later, the operator can use the remote operation device 80 to operate the raising and lowering operation means and the turning operation means of the discharge auger 32 and the operation means for turning the grain discharge cylinder 40 of the discharge auger 32. When two or more buttons are pressed at the same time, the buttons of these operation means are aggregated, for example, arranged so that at least two buttons can be pushed with one finger. Therefore, the discharge auger 32 and its grain discharge cylinder 40 can be easily operated.
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 the present invention is not limited to this.

  As described above, when the various buttons are pressed one by one, the remote operation device 80 drives the actuators 35 and 37 to correspond to the pressing operation by the control means 60, and the discharge auger 32. Are moved up and down, the discharge auger 32 is turned, and the grain discharge cylinder 40 of the discharge auger 32 is rotated.

  The remote operation device 80 includes an operation unit for raising and lowering the discharge auger 32, that is, an auger up button 80e and an auger down button 80f, and a turning operation unit, that is, an auger left turn button 80g and an auger right turn among various buttons. When the buttons 80h are simultaneously pressed, the lifting and lowering actuator 37 and the turning actuator 35 are simultaneously driven by the control means 60 so as to correspond to the pressing operation, and the discharge auger 32 is lifted or lowered while moving to the left. Or it is configured to turn right.

  Specifically, the control means 60 received while the auger ascending button 80e as the raising / lowering operation means of the discharge auger 32 and the auger left turning button 80g as the turning operation means were simultaneously pressed. The turning actuator 35 is driven while the lifting actuator 37 is driven based on the operation signal. As a result, when the auger ascending button 80e and the auger left turning button 80g are simultaneously pressed, the discharge auger 32 turns left while ascending in accordance with the pressing operation, that is, diagonally upward to the left. When it is moving toward and is not pushed, it stops without moving.

  While the auger ascending button 80e, which is the raising / lowering operating means of the discharge auger 32, and the auger right-turning button 80h, which is the turning operation means, are simultaneously pressed, the control means 60 is based on the received operation signal. Then, the turning actuator 35 is driven while the lifting actuator 37 is driven. As a result, when the auger ascending button 80e and the auger right turning button 80h are simultaneously pressed, the discharge auger 32 turns right while ascending in response to the pressing operation, that is, diagonally upward to the right. When moving in the direction and not being pushed, it stops without moving.

  While the auger lowering button 80f, which is the raising / lowering operation means of the discharge auger 32, and the auger left turning button 80g, which is the turning operation means, are simultaneously pressed, the control means 60 is based on the received operation signal. While driving the elevating actuator 37, the turning actuator 35 is driven. As a result, when the auger lowering button 80f and the auger left turning button 80g are simultaneously pressed, the discharge auger 32 turns left while descending in response to the pressing operation, that is, diagonally downward to the left. When it is moving toward and is not pushed, it stops without moving.

  While the auger lowering button 80f, which is the raising / lowering operating means of the discharge auger 32, and the auger right turning button 80h, which is the turning operating means, are simultaneously pressed, the control means 60 is based on the received operation signal. Then, the turning actuator 35 is driven while the lifting actuator 37 is driven. As a result, when the auger lowering button 80f and the auger right turning button 80h are simultaneously pressed, the discharge auger 32 turns right while descending corresponding to the pressing operation, that is, diagonally lower right. When moving in the direction and not being pushed, it stops without moving.

  In the following, the pushing operation of the auger ascending button 80e or the auger descending button 80f is “up / down button operation”, and the pushing operation of the auger left turning button 80g or auger right turning button 80h is “turning button operation”. The pushing operation of the cylinder front rotation button 80i and the cylinder rear rotation button 80j is referred to as “cylinder rotation button operation”, respectively.

  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 discharge | emits the grain in the glen tank 17 outside. And a turning actuator 35 for turning the discharge auger 32; a control means 60 for driving and controlling the actuators 35 and 37; and an auger ascent of the discharge auger 32 for remotely operating the control means 60 using wireless communication. A remote operation device 80 having a button 80e and an auger lowering button 80f (lifting operation means), an auger left turning button 80g and an auger right turning button 80h (turning operation means), and the control The means 60 is configured so that when the operation means are operated simultaneously, the actuators 3 correspond to the operations. - 37 at the same time controls and drives the one in which pivoting while lifting the discharge auger 32.

  With such a configuration, an operator who operates the discharge auger 32 using the remote control device 80 operates both the lifting button operation and the turning button operation when moving the discharge auger 32 to a desired location. The discharge auger 32 can be moved diagonally upward or downward in the left or right direction. For example, after raising the discharge auger 32 from a state where it is placed on the auger rest 21 to a height position where it does not come into contact with a part of the aircraft such as the cabin 18 or the Glen tank 17, both the raising and lowering button operation and the turning button operation are performed. By simultaneously performing these operations, the discharge auger 32 can be moved substantially linearly to the place where it is located or in the vicinity thereof. Therefore, compared with the conventional case where the discharge auger 32 is moved by alternately moving the raising / lowering button operation and the turning button operation, the distance for moving the discharge auger 32 to a desired arrangement location or the vicinity thereof is shortened. Can do. That is, the operation time of the remote operation device 80 can be shortened and the operation can be simplified. Therefore, the combine 1 can improve the workability | operativity when an operator performs the grain discharge | emission operation | work by the discharge | emission auger 32 using the remote control apparatus 80. FIG.

In addition to the above-described configuration, the combine 1 has a rotating operation unit that rotates the grain discharge cylinder 40 of the discharge auger 32 as another operation unit (that is, an elevating operation unit and a turning operation unit). ) Can be operated simultaneously.
Specifically, the cylinder front rotation button 80i and the cylinder rear rotation button 80j, which are the rotation operation means of the remote operation device 80, are both the lifting button operation and the turning button operation, or one of them. Even when the above operation is performed, the operation can be performed. That is, the control means 60 determines whether the lifting / lowering actuator 37 and the turning button are turned on the basis of the received operation signal while both the raising / lowering button operation and the turning button operation are performed. Both or one of the actuators 35 is driven. Even in such a state, the control means 60 does not stop the rotation button operation (ie, push operation of the cylinder front rotation button 80i or the cylinder rear rotation button 80j). The cylinder turning actuator 41 is driven based on the received operation signal.
It should be noted that the same configuration can be adopted when operating the cylinder front rotation button 70i and the cylinder rear rotation button 70j, which are the operation means for rotation of the machine side operation device 70.

  As mentioned above, the combine 1 which concerns on one Embodiment of this invention is the grain discharge cylinder 40 (grain discharge part) provided in the said discharge auger 32 so that rotation is possible, and the said grain discharge cylinder 40. An actuator 41 for rotating the cylinder (an actuator for the grain discharging unit), and the remote control device 80 includes a cylinder front rotating button 80i and a cylinder rear rotating button of the grain discharging cylinder 40. 80j (rotation operation means), and the control means 60 is configured so that when two or more operation means of the remote operation device 80 are operated at the same time, the actuators 35, 37, 41 correspond to the operations. Are simultaneously controlled to move the discharge auger 32 up and down, or to turn the discharge auger 32 up and down and / or to turn the grain discharge cylinder 40.

  With such a configuration, an operator who operates the discharge auger 32 using the remote control device 80 rotates the grain discharge cylinder 40 of the discharge auger 32 to place the discharge auger 32 in a desired location. There is no need to rotate the grain discharge cylinder 40 before or after turning it up and down and turning. That is, the operator rotates the grain discharge cylinder 40 while the discharge auger 32 is being lifted and swung by performing a rotation button operation while the discharge auger 32 is being lifted and swung. Can do. Therefore, the operation time of the remote operation device 80 can be shortened. Therefore, the combine 1 can improve the workability | operativity when an operator performs the grain discharge | emission operation | work by the discharge | emission auger 32 using the remote control apparatus 80. FIG.

Next, control related to operations of the lifting operation means, the turning operation means, and the turning operation means in the machine side operation device 70 and the remote operation device 80 will be specifically described with reference to the flowchart of FIG.
In the following description, the control at the time of operation of the main unit side operation device 70 and the remote operation device 80 is the same, and only the operation of the remote operation device 80 will be described.

  First, in step 101, when any one of the lifting operation means, the turning operation means, and the turning operation means is pressed in the remote operation device 80, the operation signal is displayed while the button operation continues. The data is transmitted from the transmission unit 81 to the reception unit 61 of the control means 60. The control means 60 inputs the signal received by the receiving unit 61 to the arithmetic processing device 62. Then, the control means 60 determines whether or not the operation signal input to the arithmetic processing unit 62 is an operation signal generated by any one of the up / down button operation, the turning button operation, and the cylindrical body rotation button operation. judge.

As a result, when the operation signal input to the arithmetic processing unit 62 is an operation signal generated by any one of the up / down button operation, the turn button operation, and the cylinder rotation button operation, that is, the up / down button operation, the turn When any one of the button operation and the cylinder rotation button operation is performed, the control unit 60 shifts the step to step 102.
On the other hand, when the operation signal input to the arithmetic processing unit 62 is not only an operation signal by any one of the up / down button operation, the turn button operation, or the cylinder rotation button operation, that is, the up / down button operation, the turn If any one of the button operation and the cylinder rotation button operation is not performed, the control means 60 shifts the step to step 103.

  In step 102, the control means 60 drives the raising / lowering actuator 37, the turning actuator 35 or the cylinder rotating actuator 41 corresponding to the button operation to move the discharging auger 32 up / down or turn the grain discharging cylinder 40. Turn back and forth. That is, the discharge auger 32 is raised or lowered in the up-down direction, left-turned or right-turned in the left-right direction, or the grain discharge cylinder 40 is turned forward or backward. It becomes.

  In step 103, the control means 60 determines whether or not the operation signal input to the arithmetic processing unit 62 is an operation signal resulting from any two operations of an up / down button operation, a turning button operation, or a cylinder turning button operation. Determine whether.

As a result, when the operation signal input to the arithmetic processing unit 62 is an operation signal by any two operations of the up / down button operation, the turning button operation, or the cylinder turning button operation, that is, the up / down button operation and the turning operation. Both of the button operation for turning and the button operation for raising and lowering and the button operation for rotating the cylinder are performed, or the button operation for turning and the button for turning the cylinder are operated. When both operations are performed, the control unit 60 shifts the step to step 104.
On the other hand, when the operation signal input to the arithmetic processing unit 62 is not an operation signal by any one of the up / down button operation, the turning button operation, or the cylindrical body turning button operation, that is, the up / down button operation and the turning button. Both of the operations are not performed, neither the lifting button operation nor the cylinder rotating button operation is performed, and the turning button operation or the cylinder rotating button operation is not performed. When both operations are not performed, the control unit 60 shifts the step to step 105.

  In step 104, the control means 60 simultaneously drives two actuators of the lifting actuator 37, the turning actuator 35, or the cylinder turning actuator 41 corresponding to the button operation to raise, lower, turn or turn the discharge auger 32. The particle discharge cylinder 40 is rotated back and forth. That is, the discharge auger 32 is turned left or right in the left-right direction while being raised or lowered in the vertical direction, or the grain discharge cylinder 40 is moved forward or backward while the discharge auger 32 is raised or lowered in the vertical direction. The grain discharge cylinder 40 is rotated forward or backward while the discharge auger 32 is turned leftward or rightward in the left-right direction.

  In step 105, the control means 60 determines whether or not the operation signal input to the arithmetic processing unit 62 is an operation signal generated by three operations, that is, an up / down button operation, a turning button operation, and a cylindrical body rotation button operation. judge.

As a result, when the operation signal input to the arithmetic processing unit 62 is an operation signal by three operations of the up / down button operation, the turning button operation, and the cylinder turning button operation, that is, the up / down button operation and the turning button. When all of the operations and the button operation for rotating the cylinder are performed, the control unit 60 shifts the step to step 106.
On the other hand, when the operation signal input to the arithmetic processing unit 62 is not an operation signal by three operations of the up / down button operation, the turning button operation, and the cylindrical body rotation button operation, that is, no button is operated. Will return.

  In step 106, the control means 60 simultaneously drives all of the lifting and lowering actuator 37, the turning actuator 35 and the cylinder turning actuator 41 corresponding to the button operation to turn the discharge auger 32 while raising and lowering it. The grain discharge cylinder 40 is rotated back and forth. That is, the discharge auger 32 is turned left or right in the left-right direction while being raised or lowered in the vertical direction, and the grain discharge cylinder 40 is rotated in the forward direction or the backward direction.

Further, the process proceeds from step 102, step 104, and step 106 to step 107.
In step 107, the control means 60 determines whether or not the operation signal transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing device 62 via the reception unit 61.

As a result, when the operation signal transmitted from the transmission unit 81 of the remote operation device 80 is not input to the arithmetic processing unit 62 via the reception unit 61, that is, when the button operation is released, the control unit 60 performs the step To step 108.
On the other hand, when the operation signal transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing device 62 via the reception unit 61, that is, when the button operation is continued, the control means 60 performs the step To step 101. In this case, the control means 60 continues raising / lowering or turning of the discharge auger 32 corresponding to button operation, or the back-and-forth rotation of the grain discharge cylinder 40.

  In step 108, the control means 60 stops the turning actuator 35, the raising / lowering actuator 37 or the cylinder rotating actuator 41 corresponding to the button operation, and the raising / lowering or turning of the discharge auger 32 or the grain discharging cylinder 40. Rotation of the back and forth is stopped.

In addition to the above-described configuration, the combine 1 includes an identification unit that facilitates identification of each operation unit of the remote control device 80 (that is, an elevating operation unit, a turning operation unit, and a rotation operation unit). It can be set as the structure provided.
In the present embodiment, as shown in FIG. 9, the identification means uses a surface color that can be visually identified. That is, an auger ascending button 80e and an auger descending button 80f that are lifting operation means, an auger left turning button 80g and an auger right turning button 80h that are turning operation means, and a cylinder front turning button that is a turning operation means.

The cylinder front rotation button 80i and the cylinder rear rotation button 80j, which are rotation operation means for rotating the grain discharge cylinder 40, are formed in a triangular shape in the former and in a rectangular shape in the latter. Thus, the shape is clearly different from the viewpoint of the operator.
The surface color is an example of an identification unit and is not limited to this. For example, the identification means may be a surface treatment or the like that has different tactile sensations with fingers.

Having identification means to

  With such a configuration, when the operator uses the remote operation device 80, the operation means (that is, the elevating operation means, the turning operation means, and the turning operation means) are immediately identified, and the desired operation means. Can be operated. Therefore, the workability of the grain discharge work by the discharge auger 32 using the remote control device 80 can be improved.
