EMBODIMENT OF THE INVENTION Embodiment of this invention is described in detail below based on drawing.

As shown in FIG. 1, the combine is a side view of the entire configuration example. The combine harvests the grain stem from the body supported by the right and left crawler traveling devices a and a. (B), threshing portion (c) for separating rice from the grain stem, storage portion (grain tank) (d) for accommodating threshed rice, and discharged rice out of the gas from the storage portion (d) And a steering wheel f for operating the gas auger and work device operation by the discharge auger device (grain grain discharging device) e.

The discharge auger (grain grain discharging device) 1 is opened from the upper end of the vertical axis auger 1a and the vertical axis auger 1a which rises from the storage part d and turns left and right. The turning-auger part 1b which can send out a grain egg to the side of a gas via this, and the below-mentioned radio-operated discharge auger control apparatus which adjusts the turning angle position of this turning auger part 1b by the instruction from inside and outside of a body. It consists of (2).

The pivoting auger 1b is provided with an outlet at its tip, and is held at the auger seat in the storage position, and the axis of the pivoting auger 1b is used for positioning adjustment of the outlet. The up and down motion by tilting, the expansion and contraction motion in the axial direction thereof, and the pivoting motion about the axis of the longitudinal auger portion 1a are made possible, and the power clutch (not shown) turns on the discharge. On / off is controlled. In addition, the wirelessly operated discharge auger control device 2 is operated by a remote controller (radio transmitting type operation device) 20 (to be described later) for operating the discharge auger device 1 out of the gas from the steering wheel f. The signal is received wirelessly and each device is controlled in accordance with the operation of the operating mechanism by the operator.

As shown in FIG. 2, the radio type discharge auger control device 2 performs signal processing of input and output by a control unit by a microcomputer 2a. On the input-output side, the automatic storage switch 4a, the automatic ejection switch 4b, the left and right turning manual lever switch 5, the lifting manual lever for lifting and discharging auger operation portion of the steering wheel f of the present aircraft. In addition to the switch 6, the discharge switch 7, and the elongation positioning dial 3c, a signal of an auger position sensor 3d is received. The output side drives left turn relay 11a, priority relay 11b, rising solenoid 12a, falling solenoid 12b, and discharge relay 13 to control each gig of the discharge auger. To control. In addition, in the input, the signals of the automatic storage 21a, the automatic unloading 21b, the left and right turning 22, the elevating 23, and the discharge 24 are machined by the operation of the remote manipulator 20 in FIG. Receive from the outside.

The specific control process of the control part 2a by each operation mechanism is as follows. After the lift Auger 1b is lifted from the seat by the automatic ejecting switch 4b, the swing Auger 1b is pivoted to a predetermined angle position corresponding to the ejection positioning dial 3c. By the automatic storage switch 4a, the pivoting auger 1b is pivoted to the storage position, and is driven to descend and store in the seat. By the left and right turning manual lever switch 5, the turning auger 1b is pivotally controlled through the left turning relay 11a and the priority turning relay 11b in response to the operator's operation. The lifting manual lever switch 6 lifts and lowers the turning auger 1b via the rising solenoid 12a and the lowering solenoid 12b. By the discharge switch 7, the electric clutch of the grain-egg feed system is put in / off control via the discharge relay 13. The auger position sensor 3d feeds back the turning angle position of the turning auger 1b. In addition, the discharge auger 1 is driven and controlled by the remote control unit (wireless operation device) 20 in the same manner as the operation mechanism of the main body.

The specific arrangement of the switches of the remote control unit 20 includes the switches 22a and 22b of the left and right sides for the left and right turning operation of the discharge auger 1, and the top and bottom positions for the vertical operation. Each switch 23a, 23b, a "new" "axis" switch 25a 25b for expansion and contraction operation, a "discharge stop" switch 24c for turning on / off discharge, and a "loading and discharging" for storing and discharging. Position the switch 21c.

The "discharge stop" switch 24c is a common (single) switch means for turning on / off discharge, in which the discharge auger 1 is ejected at the storage position and is accommodated at the discharge position to control the control unit 2a. ) Outputs control. In addition, the "storage storage" switch 21c is a common switch means for the unloading operation and the storing operation. When the discharge auger device 1 is in the storing position, the unloading operation is performed. The control unit 2a is configured to output.

By configuring the reverse operation as a common (single) switch means in this way, the complexity of the operation unit in the case of disposing the individual switches is eliminated, and complicated operation of selecting one of the switches is required. Since it does not, it is possible to improve operability. In this case, the same effect can be obtained even if it is set as the structure which inverts alternately by a corresponding operation | movement every time the common switch means is operated.

The ejection operation, the storing operation by the "storage ejection" switch 21c, and the ejection auger operation by the "discharge stop" switch 24c are discharged under the condition that the operation signal of the switch is performed twice within a predetermined time. The control part 2a is comprised so that each operation | movement of the auger apparatus 1 may be controlled. As shown in the timing chart of FIG. 4, the operation reaches the first operation within a predetermined time (for example, 500 ms) and reaches a predetermined time leading to an opening within a predetermined time (for example, 500 ms). The operation of 2 is conditional. In the storing operation (including the operation in the loading position) of the discharge auger, the discharge operation of the discharge auger is stopped by a signal of the first operation.

In this way, the operation of the discharge auger device is limited to the operation performed twice within a predetermined time for the ejecting operation, the storing operation, and the discharge auger operation by the remote control unit 20, thereby simplifying the switch operation. By being able to distinguish the intentional switch throttling with respect to the contact, it is possible to reliably avoid the situation where the discharge auger device is operated in the case of an operator accidentally touching the switch, or for the careless handling of the remote controller.

In addition, when the discharge operation is configured to be forcedly stopped by the first operation in the storing operation (including the operation at the loading position) of the discharge auger, as shown in the timing chart of FIG. Since the discharge auger can be controlled and output in advance, it is possible to avoid the situation of starting the storing operation while continuing the discharge operation, and to immediately stop the discharge operation in response to the switch operation. It is possible to cope.

Regarding the relationship between the steering wheel f and the remote control unit 20 of the machine, in a given case, the remote control unit 20 is given priority to drive control the discharge auger device 1. Automatically storing or automatically unloading of the discharge auger 1 is started by the automatic storage switch 4a and the automatic unloading switch 4b on the main body side. In case of pressing the switch of swing operation and expansion / retraction movement, it is configured to immediately focus on automatic storage or automatic loading. By controlling in this way, even if there is an obstacle in the blind spot of the operator of this machine side, it is safe because a work assistant can stop auger movement with the remote control 20. FIG.

Next, as shown in the operation plan view of the discharge auger 1 of FIG. 6, the turning angle range B which can be discharged on / off by the remote control unit 20 is the case of operating the steering wheel of the present gas. The discharge on / off is configured to be limited to a narrower range than the angle range (A). By limiting the angular range in this way, it is possible to prevent the malfunction of the discharge auger device 1 due to the misoperation of the remote control unit 20.

Next, as shown in the plan view of the storage state of the discharge auger device 1 in FIG. 7, the large and small angle ranges A and B for determining the storage position are set, and the large angle when the discharge clutch is put into operation. It is comprised so that a range A may be made into a condition and a small angular range B is made into a condition when it performs an automatic ejection operation. Due to the difference in the angular range as described above, when the discharge auger device 1 is in the storage position, the handling can be secured as the allowable range for the contents of the operation by the remote controller 20.

Next, as shown in the signal level characteristic diagram of the remote control unit 20 of FIG. 8, the reception level of the signal of the remote control unit 20 is divided into high and low (H, L), and automatically loaded and automatically The reception sensitivity is set at a low level (L) for storing and discharging clutches, and the reception sensitivity is set at a high level (H) for other manual operations (up, down, left, right, expansion and contraction), automatic stop, and discharge stop. This high and low reception level classification (H, L) is configured to receive only signals above the reception level, and makes it difficult to receive the reception sensitivity at a low level (L) for a specific operation of the discharge auger device 1. By doing so, it is possible to prevent a situation in which an emergency stop signal cannot be received when it is received near the limit of reception sensitivity.

Next, as shown in the display form of the operation monitor of FIG. 9, an indicator D of the operation monitor is provided, the operation information is displayed on this indicator D, and the transmitter of the remote controller 20 Configure to indicate each identification code of the receiver. In a system that operates when the identification codes of the transmitter and the receiver do not coincide with each other, even when the remote controller 20 is operated, the discharge auger apparatus 1 of the present gas does not perform a corresponding operation. In addition to the failure and radio interference of the equipment, if there is an inconsistency in the identification code, and if the inconsistency in the identification code is the cause, it is possible to check the display based on the display of the indicator. ) Becomes easy. This is particularly effective in a large group that handles a plurality of remote controls 20.

Next, as shown in the switch display example of the remote control unit 20 in FIG. 10, the turning direction switch is set to the "storing side" and "loading side", and the discharge auger apparatus 1 is moved to the storage position corresponding to each. It is comprised so that drive control may be carried out by the turning operation of a returning direction, and the turning operation of a large elongation direction. For example, as shown in the plan explanatory drawing of the turning operation of FIG. 11, when the "receiving side" is pressed, if the auger position is left (A) from the storing position C, it will output preferentially, If it is right, it will turn left. When the "outboard side" is pressed, the left pivot output is made if the auger position is left of the storage position, and the first output is made if the auger position is left of the storage position.

In the conventional "left" and "right" turning operation, when the operator is located at the rear end side of the ocher, the operation direction is in the opposite direction to the display of the switch, but it is confused, but by the above configuration, regardless of the position of the operator, Since the auger operation direction becomes clear, it is possible to improve operability and safety.

Regarding the above-described control processing, specific examples of the device configuration and the processing procedure are shown by the drawings.
