The movable transfer cylinder 7 is stopped in the auger maximum stretched state shown in FIG.

  FIG. 7 is a perspective view of a portion of the operation panel 90 provided on the side of the combine cockpit 40 that is related to the operation of the threshing auger 5. On the operation panel 90, there are a threshing clutch operating lever (a potato discharging lever) 41, an auger manual operating lever 42, a threshing operation emergency stop switch 91, an automatic storage switch 111, an automatic extension switch 112, a manual extension switch 92, and a manual reduction. A switch 93, an overhang position setting dial 116, a zoom setting dial 94, and the like are arranged.

  The threshing clutch operating lever 41 is connected to the threshing clutch device 12 (FIG. 4) with an operation wire (not shown) to perform intermittent operation of the threshing clutch device 12, and to perform the discharging operation and stopping of the straw (grain). The auger manual operation lever 42 turns on the manual lever (left-right turn) switch 113 (FIG. 9) when the lever 42 is tilted left and right to turn the grain auger 5 left and right. Is tilted back and forth, the manual lever (lifting / lowering) switch 114 (FIG. 9) is turned on to raise and lower the grain auger 5 up and down.

  Moreover, FIG. 9 shows the block diagram of the circuit of the control apparatus 100 in connection with control of the threshing auger 5 of embodiment of this invention. The control device 100 has an automatic storage switch 111, an automatic extension switch 112, a manual lever (left-right turn) switch 113, a manual lever (lifting / lowering) switch 114, a discharge switch 115, an extension position through an input interface 102 with the CPU 101 as the center. From the setting dial 116, remote control automatic storage button 117, remote control automatic extension button 118, remote control manual (left / right turn) button 119, remote control manual (lifting / lowering) button 120, remote control discharge button 121, remote control extension button 130, remote control reduction button 131, etc. Entered.

  Further, the CPU 101 computes the result of processing the input signal via the output interface 103, and the expansion relay 123, the reduction relay 124, the left turn relay 125, the right turn relay 126, the cerealing auger raising solenoid 127, and the sheding auger lowering. The solenoid 128, the discharge relay 129 and the like are operated.

The operation of the threshing auger 5 by the control device 100 is as follows.
First, the automatic operation of the threshing auger 5 by the control device 100 will be described. By using the overhang position setting dial 116, the overhang angle, the turning angle, and the extension length of the grain auger 5 are set. When the automatic extension switch 112 is turned on after the setting is completed, the threshing auger 5 is automatically moved to the setting position in accordance with the command stored in the CPU 101 and the setting value of the setting dial 116.

  That is, first, the raising solenoid 127 is operated, and the threshing auger 5 is separated from the auger receiver 35 and raised. Next, the left turn relay 125 or the right turn relay 126 is actuated to drive the turn motor 28 (FIG. 4) to the turn angle set on the overhang position setting dial 116, and the turn angle is detected by a turn angle sensor (not shown). Then, the threshing auger 5 is turned by a predetermined amount according to the set value. During this time, the extension relay 123 or the reduction relay 124 is operated to the set extension length to drive the expansion / contraction control motor 24 having a built-in zoom length detection potentiometer, and the threshing auger 5 is zoomed in or out. When the threshing auger 5 reaches the set length, the zoom extension or reduction ends.

When the automatic storage switch 111 is turned on, the CPU 101 automatically stores the threshing auger 5 in the storage position of the auger receiver 35 in accordance with the storage position and procedure command stored in advance.
That is, when the grain auger 5 is at a position shorter than the intermediate state or a position longer than the intermediate state, first, the lifting solenoid 127 is operated to drive the lifting hydraulic cylinder 27 to bring the grain auger 5 to a safe height. Raise.

Next, the right turning relay 126 or the left turning relay 125 is actuated to the upper side of the auger receiver 35 to drive the turning motor 28 to turn the grain auger 5. Based on the output signal of the turning angle sensor (not shown), it is detected that the grain auger 5 has reached above the auger receiver 35, and the turning is finished.
During this time, the extension relay 123 or the reduction relay 124 is operated, and the expansion / contraction control motor 24 is driven to extend or reduce the cerealing auger 5, and the output signal of the intermediate limit switch S3 causes the cerealing auger 5 to be in an intermediate state. Stretch or shrink to length (see FIG. 5).

  Finally, the lowering solenoid 128 is operated to reduce the lifting hydraulic cylinder 27, the cerealing auger 5 is stored in the auger receiver 35, and the operation of an auger receiving switch (not shown) in the auger receiver 35 is detected. End automatic storage.

  Next, with reference to FIG. 7, the manual operation of the grain auger 5 will be described. Of the manual operations performed by tilting the auger manual operation lever 42 shown in FIG. When the switch on the ascending side of the manual lever (elevating / lowering) switch 114 (not shown) in the lever guide of FIG. 8 is turned on, the elevating solenoid 127 is activated, and the elevating hydraulic cylinder 27 (see FIG. 4). The cerealing auger 5 rises due to the extension of, and continues to rise until a rise limit switch (not shown) is operated while the switch on the raising side of the manual lever switch 114 is on.

  When the auger manual operation lever 42 is tilted forward, and the switch on the lower side of the manual lever (lifting / lowering) switch 114 (not shown in the lever guide of FIG. 8) is turned on, the lowering solenoid 128 is actuated and the lifting hydraulic pressure is increased. The grain auger 5 is lowered by the reduction of the cylinder 27, and the auger receiving switch (not shown) is turned on until the lower limit switch (not shown) is operated while the lower switch of the manual lever switch 114 is turned on. Continue descending until

  When the auger manual operation lever 42 is tilted to the right and the right switch (not shown) of the manual left / right turn switch 113 is turned on, the right turn relay 126 is activated, and the right switch of the manual left / right turn switch 113 is on. Until the right turn limit switch (not shown) is actuated, the rotation of the auger turning motor 28 (see FIG. 4) causes the whipping cylinder 4 and thus the cerealing auger 5 to turn right. Further, when the auger manual operation lever 42 is tilted to the left and the left switch (not shown) of the manual left / right turn switch 113 is turned on, the left turn relay 125 is activated and the left turn switch is turned on while the manual left turn switch is on. Continue to turn right until a limit switch (not shown) is activated.

  When the manual extension switch 92 or the manual reduction switch 93 is turned on, the auger extension relay 123 or the reduction relay 124 is activated, and the threshing auger 5 is extended or reduced by the rotation of the extension / contraction control motor 24. While the manual reduction switch 93 is on, the threshing auger 5 continues to be extended or reduced until the limit switch S2 or S1 is operated.

  The left / right turning operation, the up / down raising / lowering operation, and the expansion / contraction operation of the cerealing auger 5 by manual operation can be operated independently or simultaneously.

  After the setting of the position of the auger discharge port 9 of the threshing auger 5 by manual turning and manual extension or automatic extension, the threshing clutch operating lever 41 in the cockpit 40 is manually operated, and when the threshing clutch is connected, The grain operation is started, and the transportation of the grains in the Glen tank 3 is started. When the threshing clutch operating lever 41 is manually operated in the opposite direction and the threshing clutch device 12 is disconnected, the threshing operation is stopped, and the transportation of the grains in the glen tank 3 is stopped. Stopping the threshing operation can also be performed by the cerealing operation emergency stop switch 91.

  Further, in this embodiment, the threshing auger 5 is configured to be remotely operable, and the layout of the switch group of the remote control transmitter 44 shown in the plan view (a) of FIG. 10 and the perspective view of FIG. , Down, left turn, right turn, extension, reduction, discharge, overhang / storage.

That is, switches 45a and 45b for moving up and down the grain auger 5 and switches 45c and 45d for moving left and right are provided, and further below that, an extension switch 45e and a reduction switch 45f, a discharge switch 45g, and an overhang / storage switch 45h (collectively referred to as remote control operation switch 45) are provided separately.
The overhanging / storing switch 45h is pushed once to overhang the cerealing auger 5, and the husk auger 5 is housed in the auger receiver 35 when pushed twice.

  Thus, by arranging the switch groups 45a to 45h in the order of the operation operation of the threshing auger 5, the operability of the remote control transmission device 44 is improved as compared with the conventional product. The antenna 22 of the receiving device (not shown) of the remote control transmitting device 44 is attached to the rear upper surface of the Glen tank 3.

Further, if a display device for battery confirmation is provided at the upper left part of the remote control transmitter 44, it may operate due to a battery, so that it may not operate due to a battery exhaustion. Therefore, if the battery confirmation display is always turned on, the battery will be consumed, so it is desirable to display it when operating the radio. In this embodiment, a display 45i is provided at the upper left and upper part of the operation surface of the transmitter so that the remaining battery level can be confirmed during operation.
In addition, since the display 45i is disposed at the upper left corner of the remote control transmission device 44, even if the remote control transmission device 44 is held, it is not hidden by the finger.
Further, in this embodiment, when the discharge clutch device 12 is in the engaged state, that is, when the grain is being discharged, the automatic extension or automatic storage of the grain auger 5 is performed even if the extension / storage switch 45h of the remote control transmission device 44 is pressed. I will not. This is to prevent the occurrence of problems such as spilling of cocoons when the remote control transmission device 44 is inadvertently operated during grain (rice cake) discharging and the grain auger 5 is automatically extended or automatically stored.

  Further, the layout of the switch group of the remote control transmitter 44 shown in the plan view of FIG. 14 includes switch groups 45a to 45d for up, down, left turn and right turn, expansion / extension switch 45e ', reduction / storage. The switch groups 45a to 45d for up, down, left turn, and right turn are configured to be movable by a single switch operation, and are divided into the switch group of the switch 45f 'and the discharge switch 45g'. The storage / discharge 45e ′ to 45g ′ switch group can be moved by operating a plurality of switches, and a confirmation / stop switch 45h ′ may be laid out. Since the confirmation / stop switch 45h ′ is provided in the configuration shown in FIG. 14, after the confirmation / stop switch 45h ′ is pressed once, the expansion / extension, reduction / retraction, or discharge switches 45e ′ to 45g within a certain time. Each action can be executed by pressing any of '. Further, when the confirmation / stop switch 45h ′ is pressed during the execution of the expansion / extension, reduction / storage, or discharge operation, the respective operations can be stopped.

  The extension / extension switch 45 e ′ functions as an extension switch when the grain auger 5 is stored in the auger receiver 35, and functions as an extension switch when the grain reduction auger 5 is projected. Further, when only the reduction / storage switch 45f ′ is pressed, it functions as a reduction switch when the cereal auger 5 is overhanging. After 45h ′ is pressed, if the 45f ′ is pressed within a predetermined time, the threshing auger 5 When this is located at a position other than the position of the auger receiver 35, it functions as an automatic storage switch for automatically storing the auger receiver 35.

In this way, the switch group 45 of the remote control transmitter 44 is divided into a switch that can be moved by a single switch operation and a switch that can be moved by a plurality of switch operations. Since the operation is impossible only by the operation, the cereal auger 5 does not start when the switch is inadvertently turned on, and the straw does not spill from the cereal auger 5.
In addition, the cereal auger 5 cannot be operated by the remote control transmission device 44 when the cereal auger 5 is in the storage position. The reason is that when the grain auger 5 is in the stowed position and the remote control transmitter 44 is inadvertently operated and self-draining, troubles such as spillage occur.

On the other hand, when grain discharge is performed using a not-shown straw discharge switch or straw discharge lever 41 (FIG. 7) of the operation seat 40, the grain can be discharged even if the grain auger 5 is stored in the auger receiver 35.
The operation of the remote control transmitter 44 may be configured to issue an alarm when the cerealing auger 5 is operated by a remote control transmitter 44 other than the set remote control transmitter 44.

In the cerealing auger 5 that is operated wirelessly by transmitting an ID signal representing an individual of the remote control transmission device 44, an error detection signal (checksum) that proves the correctness of the signal, and an operation command signal, for example, Although the transmission signal can be correctly received by the checksum, a function is provided for notifying the outside that the ID signal is different when an ID signal different from the registered ID signal is received.
This is because, when working with a plurality of combines for hire, etc., the assistant who collects the soot may work while holding a plurality of remote control transmitters 44, but remote control transmission corresponding to each combine In this configuration, an alarm is issued when the device 44 is not used.

  When the cerealing auger 5 that is operated by remote operation does not operate, the remote control transmission device 44 does not operate due to a battery exhaustion or the like, or is a remote control transmission device 44 that does not correspond to the combine to be operated, or Although it is compatible, it is unclear whether it will not work due to noise interference. It is possible to improve the operability of the remote control transmitter 44 by issuing the alarm to notify these differences.

  Further, as shown in the flow of FIG. 11, the storage function of the remote control transmitter 44 is activated (a single switch or a plurality of switches may be used), and when the raising switch 45a is pushed to raise the threshing auger 5, it is not discharged for the first time. You may comprise so that the grain auger 5 may be accommodated in the auger receptacle 35. FIG.

  The sensing time of the storage switch is made longer than the other operation switches, and safety is improved so that the storage operation is not performed only by inadvertently pressing the storage switch, but the operator puts the remote control transmitter 44 in a pocket etc. If the storage switch is pressed in this state, the threshing auger 5 may be stored.

  In order to prevent the above problems, the flow shown in FIG. 11 is configured to start safety by pressing the storage switch and then pressing the raising switch 45a to improve safety. In addition, when the second push switch is raised to the switch 45a and the controller does not sense the input of the storage switch, the grain auger 5 only rises, so that the grain is removed from the grain auger 5. Since it does not spill out and there is little risk of hitting an object other than the combine, the operational safety of the threshing auger 5 can be ensured.

  The flow shown in FIG. 12 is a combine that is configured such that when the raising switch 45a is operated after the storage switch is pressed, the threshing auger 5 can be stored for the first time. It is an operation | movement control flow of the threshing auger 5 at the time of making. This is to prevent the automatic storage from starting if the storage switch is accidentally pressed when the raising switch 45a is operated.

  Further, when the cerealing auger 5 is automatically extended by the remote control transmission device 44, the fixed position (for example, as shown in the plan view of FIG. 13, as shown in the plan view of FIG. 13) regardless of the setting of the extension position setting dial 116 (FIG. 9). It may be set so that it can be projected to the rear. This is because even a beginner can safely operate the threshing auger 5 with the remote control transmission device 44.

  When a person other than the operator performs the automatic extension of the threshing auger 5 from the outside of the combine, there is a problem that the operator protrudes to an unexpected position when the extension position setting dial 116 is operated. In operation, the threshing auger 5 can be projected at a fixed position at all times, which is safe.

  Further, when the remote control transmission device 44 shown in FIG. 15 is used to specify the automatic overhang position of the threshing auger 5 by remote control operation, for example, the left direction, the right direction, or the rear direction, the overhang position is set on the remote control transmission device 44 side. Because it can be specified, operability is improved.

  The switch group layout of the remote control transmitter 44 shown in FIG. 15 is made up of up, down, left turn, right turn switch groups 45a to 45d, extension switch 45e, reduction switch 45f, discharge switch 45g, and storage switch 45h ". Further, the overhang switch group is divided into a left switch 45m, a right switch 45j, and a rear switch 45k.

  Although not shown, if the operation level of the remote control transmitter 44 can be set arbitrarily, the remote control operation content can be limited according to the skill level. For example, the remote control transmission device 44 owned by the operator can perform all remote control operations such as an automatic turning switch and a discharge switch, and the remote control transmission device 44 possessed by the assistant cannot perform all the above operations. By doing so, it becomes possible to remotely control the combine with high safety.
