  In the case of the remote control device for agricultural machines in the prior art, when a plurality of agricultural machines are replaced with the tractor, the mechanism for operating the operating machines differs, so a control box provided with a dedicated control circuit, or a dedicated operation switch A controller provided with a remote control function is required, which hinders the cost reduction of the farm work machine with a remote control function. For this reason, the remote operation part provided in the tractor driver's seat side is made common, and even if the farm equipment side is replaced, the remote operation part on the tractor driver's seat side can be used in common, and the remote operation control device for farm work that is easy to maintain is provided. For the purpose.

  In order to solve the above-mentioned problems, a farm work machine with an electric actuator mounted on a tractor, a controller for remotely instructing the movement of the electric actuator, and a controller is provided in the controller. A relay box that causes the electric working unit on the farm work machine side to execute the operation according to the instruction, and the controller is provided in the vicinity of the tractor driver's seat so that it can be operated. The controller is common to a plurality of farm work machines mounted on the tractor. The control circuit of the controller determines the model of the farm equipment and connects the farm equipment harness attached to the tractor to the controller harness on the tractor driver's seat side. The machine automatically switches to the control circuit for the machine, and the control circuit determines the model and determines the failure for each connected work machine. Provided with a circuit, when a malfunction occurs in the electric operation part or the electrical component part, it provides an electric remote operation control device for an agricultural machine to be mounted on a tractor characterized by displaying the content of the malfunction on the display panel of the controller. is there.

  With the configuration as described above, the remote operation control unit can be used in common for a plurality of farm work machines, so there is no need to prepare a plurality of remote operation control units provided on the driver's seat side of the tractor. Subsequent farm machines can be provided at low prices. In addition, when working with multiple farm machines replaced by a tractor, the farmer's harness is connected to a remote control unit provided on the driver's seat side of the tractor. Is automatically switched to the control circuit of the connected agricultural machine, so that it is possible to prevent a trouble of the agricultural machine due to an erroneous control circuit being set by an operator's erroneous operation or forgetting to switch the control circuit.

  At the same time as switching the control circuit, the failure determination control circuit automatically switches to a circuit that matches the installed work implement, and when a failure occurs, the failure location of the installed work implement is accurately displayed on the controller. Can be easily and quickly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view of a controller, FIG. 2 is a block diagram of a remote operation control device, FIG. 3 is a control flow diagram of the remote operation control device, FIG. 4 is an explanatory diagram of a model discrimination circuit, and FIG. The block diagram is shown.

  FIG. 1 is a perspective view showing an example of a controller provided with a display panel for displaying a failure occurrence location when a failure occurs. Each operation switch 10B is arranged on the main body of the controller 10, and an operation failure occurs in the apparatus. In such a case, the defective part is displayed on the display panel 10A provided on the same surface as the operation switches 10B are arranged.

  In FIG. 2, (t1) shows what is installed on the tractor side, and (t2) shows each agricultural machine side. The controller 10 is an operation unit for an operator to instruct the operation of the farm work machine, and includes a control device 11 that controls the entire remote operation control device, a switch input unit 12 that is directly operated by the operator, and a defect location. The display unit 13 includes a display 13 and a lamp output unit 14 that displays various lamps.

  By connecting the model discriminating connector 31, the control device 11 discriminates the model of the agricultural machine based on the information from the harness of the connected agricultural machine, and automatically switches to the control circuit for the connected agricultural machine. .

  The circuit of the control device 11 is activated by a signal input by the switch input unit 12 and causes each actuator 32, which is an electric operating unit of the farm work machine, to execute an operation via the relay box 2 based on information from the sensors 30. .

  These electric actuators operate using the battery 20 installed in the tractor as a power source. However, the gist of the present invention does not change even if a power source installed other than the tractor is used.

  In FIG. 3, when a connector for model discrimination is connected (S1) and the controller is turned on (S2), each switch is checked (S3), and if there is an ON operation switch, an error is displayed (S11). Next, a model discriminating circuit operates from harness information of the connected farming machines (S4), a model set in advance by calculation is identified (S5), and a switch array is defined for the identified farming machine (S6). Then, each switch and sensor to be used is checked (S7), and if there is an abnormality, an error is displayed (S10). If there is no abnormality, the work can be started (S8), and the operation mode is checked (S9) every time the agricultural machine is operated, and if there is an abnormality, an error is displayed (S10).

  For error display, there are a method of displaying numbers and symbols on the display panel 10A and checking and operating a defective portion corresponding thereto, and a method of displaying the defective portion and the content of the defect directly on the display panel 10A with characters and pictures. .

  FIG. 4 is a diagram for explaining how the control circuit determines the model. In this example, an example in which the model determination connector has four circuits is used.

  The assignment of numerical values for the four circuits of the control device 11 is as follows: A is 1, B is 2, C is 4, D is 8, and the harnesses of each farm work machine are classified by the combination of grounded circuits. When only A is grounded as shown in (a), the assigned numerical value of the control unit is only 1, and the calculation result is 1 and it is determined that the farm equipment is a, and only B is grounded as shown in (b). And the control unit's assigned numerical value is only 2, and the calculation result is 2 and it is determined as the farm work machine b. In the case of (c), if A and B are grounded, the control unit's assigned numerical value is 1 and 2. Becomes 1 + 2 = 3, and it is determined as the farm machine C by the calculation result 3.

  Thus, in the case of a 4-circuit connector, 16 combinations are possible as shown in the table of (D), and 16 types of agricultural machines can be set. In this example, one is used as an inspection mode. Yes. By changing the number of connectors, the number of set models can be changed.

  In FIG. 5, the overall configuration of the apparatus will be described. When the electric actuator of the entire apparatus operates using the battery 20 as a power source and connects the model determination connector 31, whether the connected farm work machine is a plowing farm machine a by the action of the control device 11 in the controller 10; It is determined whether it is a paddy farming machine b, a fertilizer application farming machine c, or another working machine, and the control circuit is automatically switched to the connected farming machine control circuit.

  When the operator instructs the controller 10 to execute the operation of the electric operation unit of the farm work machine, the relay box 2 directly executes the operation of the electric operation unit of the farm work machine mounted on the tractor according to the signal of the controller 10. When a problem occurs, information is displayed on the display panel 10A of the controller.
