The pair of left and right lift arms 12, 12 are attached to a hollow shaft 23 provided horizontally on the upper part of the machine frame 22 of the main tractor machine 2. A drive arm 24 is integrally provided on the hollow shaft 23, and a piston rod 28a of a lifting hydraulic cylinder 28 is connected to the tip of the drive arm.

When this hydraulic cylinder 26 is extended, the lift arm 12
, 12 are swung upwards, and when retracted, the lift arms 12, 12 are swung downwards.

Further, a rotation shaft 30 is provided inside the hollow shaft 23 so as to be rotatable with respect to the hollow shaft 23.
Sensor arms 31 and 31' are integrally provided at both the left and right protruding ends of the sensor arms 31 and 31', respectively. A sensor rod 32 is attached to the sensor arm 31 on the lift rod 14 side (left side).
Further, a cylinder type stroke sensor 33 is attached to each sensor arm 31' on the lift rod cylinder 20 side (right side). The lower ends of the sensor rod 32 and the stroke sensor 33 are connected to the lower links 11, 11' at positions closer to the main tractor machine.

Next, FIG. 5 is a diagram showing the configuration of the working section control device 40 of this agricultural working machine. A control box 4 installed at an appropriate location on the tractor main machine 2 or rotary tiller 5
1 includes a controller 43 that serially inputs and outputs data over time, and a connector 44 attached to the controller 43. The controller 43 includes an inclination sensor 4B that detects the degree of inclination of the tractor main machine 2 in the left-right direction, a lift arm angle sensor 47 that detects the amount of rotation of the lift arms 12, 12, and the stroke sensor 3.
3. The draft sensor 49 that detects the load applied to the top link 10, the depth sensor 50 that detects the plowing depth of the rotary tiller 5, and the lift arm 12 have been rotated to just before the upper limit position in the mechanically rotatable range. An upper limit detection sensor 51 for detection, a position lever 53 for setting the vertical position of the lift arm 12, an inclination angle setting device 54 for setting the horizontal inclination (for example, horizontal) of the rotary tiller 5, which is a working part, and the rotary tiller. A plowing depth setting device 55 for setting the plowing depth of No. 5, and an upper limit setting device 56 for setting the upper limit of rotation of the lift arm 12 are connected, and the data supplied from these is processed to control the rolling proportional solenoid valve. 58 and the lifting proportional solenoid valve 58. In the figure, 60 is a manual switch for raising and lowering the lift arm, and 81 is a sensitivity changeover switch. The connector 44 is connected to a monitor 63 installed outside the control box 41. The monitor 63 can be connected to and removed from the connector 44, and other monitors, microcomputers, etc. can be connected instead.

Data supplied to the controller 43 from the various setting devices and sensors is transmitted to the monitor 83 as a serial signal together with a clock signal. As shown in FIG. 6, serial signal A is transferred one bit at a time on clock signal B. The serial signal A transferred to the monitor 63 is
It is input to CPtJ85 via photocoupler 64. When the operator sets desired data (setting values, sensor values) using the monitor switch 67, the data is converted into an appropriate numerical value and displayed on the display section 6.

Further, this monitor 63 is provided with an alarm buzzer 70, which sounds an alarm and displays the inclination when the inclination sensor 46 exceeds ±20 degrees, and when the lift arm is operated with the manual lift switch 60 in the lower position. When the detected value of the angle sensor 47 rises to the second limit set value, the lift arm angle is displayed and an alarm is sounded. Further, when the lift arms 12, 12 are lowered to the set position of the position lever 53 during work using draft control or depth control, the lift arm angle is displayed and an alarm is sounded.

In the case of the control system of this example, the setting by the position lever 52 is given top priority, and the lift arms 12, 12 are not lowered below this set value. In other words, a buzzer sounds to notify you that the automatic controls (draft control, depth control) will no longer work.

When transmitting data as 30-byte information, the transmission format is as shown in Table 1, for example.

In this way, the work unit control device 40 is provided with a detachable monitor 63 in addition to the controller 43, so that the control box 41 that houses the controller
It is small in size, and the installation location can be chosen freely. Further, the monitor 63 may be installed anywhere, for example, if it is installed in the cockpit, the data value at the time can be checked at any time during work, and appropriate control can be performed.

Next, FIG. 8 shows a different embodiment. This work part control device 80 is separately provided with a controller 81 for tilt control and a controller 82 for lift control. Sensors, setting devices, etc. are connected as shown in the figure. Based on the data inputted from these, an output command is issued from the controller 81 to the rolling valve 58, and an output command is issued from the controller 81 to the lifting valve 58. These controllers 81 and 82 are also provided with connectors 84 and 85, respectively, as in the previous example, and data is transmitted to the monitor 63' through these connectors. The monitor 63' is provided with a changeover switch 87, so that the operator can select and receive these data for tilt control and data for elevation control.

In this example, we have taken up a tractor equipped with a tiller as a working part, and have explained the controllers for controlling the tiller's horizontal inclination and lifting/lowering, but the same applies to other bird working machines, and each work By providing a connector on the unit control controller, necessary data can be transmitted to an external monitor.

[Effects of the Invention] As is clear from the above description, the controller for controlling the working parts of agricultural machinery, etc. according to the present invention can transmit data to an external monitor via the connector, so that data can be transmitted within the controller. It is now possible to effectively utilize internal information.

In addition, the control box can be made smaller.
