BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a control mechanism of a tractor working machine.

[0002]

2. Description of the Related Art Conventionally, control mechanisms such as horizontal control and plowing depth control of a tractor working machine are performed directly by hydraulic pressure or electricity using wires, links or cords. However, since the lengths of wires and links are different depending on the type of work machine, wires and links dedicated to the model are required, and the performance of the wires and links changes due to wear and elongation. Also, when attaching and detaching the working machine, it is necessary to attach and detach wires and cords at the same time, and it is difficult to attach and detach the working machine.

[0003]

Therefore, the present invention aims at making the control mechanism of the tractor work machine wireless without using wires, links, cords and the like.
It is an object of the present invention to stabilize the performance of a working machine and to make it possible to easily attach and detach the working machine.

[0004]

As a means for solving the above-mentioned problems, the present invention provides a tractor body with a transceiver, a work machine with a transceiver, and a weak transmission from the transceiver to the transceiver. In this configuration, the working machine can be controlled by transmitting an appropriate radio wave, and the output of the transceiver can be adjusted.

[0005]

Next, the operation will be described. Since the receiver 1 provided on the tractor T body is configured to receive a weak radio wave from the transmitter 2 provided on the rotary plow R as a working machine, the automatic leveling of the rotary plow R is performed. The control is as follows. The inclination detection sensor 3 provided in the rotary tillage device R detects the inclination or unevenness of the field, transmits the detected value as a signal from the transmitter 2 to the receiver 1, and receives the signal by the radio wave. The control circuit 6 connected to the machine 1 is controlled by controlling the expansion and contraction of the tilt control cylinder 15,
The tillage depth control of the rotary tillage device R is performed by the rear cover 1.
9 detects the rotation angle of the rear cover 19, and uses the detected value as a signal from the transmitter 2 to the receiver 1
And the control circuit 6 connected to the receiver 1 by the signal of the radio wave, the cultivation depth such as shallow cultivation, deep cultivation, etc. by the tilling claw 7 of the preset rotary tilling device R regardless of the unevenness of the field. Transmission case 10 so that
This is performed by controlling the rotation of the lift arm 23 provided in the upper hydraulic device 21 and controlling the lifting and lowering of the rotary tilling device R. As described above, the control mechanism of the deep tillage control and the horizontal control of the rotary tillage device R, which is a working machine,
It can be controlled wirelessly by radio waves.

Next, an embodiment of the present invention will be described. FIG.
2 is an overall side view of the wireless control tractor of the present invention, and FIG. 2 is an overall side view of the tractor provided with the optical communication device H.

An embodiment of the present invention will be described with reference to a tractor in which a rotary tilling device is mounted on a rear portion as a working machine shown in FIG. 1. A receiver 1 is provided on a tractor T main body, and a rotary tilling device R is provided in a rotary tilling device R. A transmitter 2 is provided. The rotary tilling device R is attached to a three-point link type working machine mounting device at the rear of the tractor T, and a lower link 8 projects from the rear of the transmission case 10 of the tractor T. , A rotary tillage device R is pivotally connected via a pivot pin 9. In addition, mission case 10
A top link hinge 11 protrudes from a rear portion of the top link hinge 11. A top link 12 is provided on the top link hinge 11, and a top link mast 13 of a rotary tilling device R is pivotally connected to a tip of the top link 12. ing. Further, a lift arm 23 is protruded from the hydraulic device 21 mounted on the upper part of the transmission case 10, and a lift link 24 is provided at the tip of the lift arm 23. The lower link 8 is pivotally connected. An inclination control cylinder 15 is interposed in the lift link 24,
Automatic horizontal control of the rotary tilling device R is performed by expansion and contraction of the tilt control cylinder 15.

The automatic horizontal control of the rotary tilling device R is performed by a tilt detecting sensor 3 provided in the rotary tilling device R, which detects the tilt or unevenness of the field, and outputs the detected value as a signal from the transmitter 2 to the receiver. 1 sent by weak radio waves,
The control is performed by the control circuit 6 connected to the receiver 1 controlling the expansion and contraction of the tilt control cylinder 15 by the signal of the weak radio wave.

A depth handle 17 is provided between the top link mast 13 and the depth frame 16, and the depth handle 16 is rotated by rotating the depth handle 17.
The tilling cover 18, the rear cover 19, and the side plate 20 can be integrally adjusted via. A vertical rod 25 is erected on the depth frame 16, and a depth wheel 22 is supported on the vertical rod 25. The cultivation cover 18, the rear cover 19, and the side plate 20 are rotatably supported around the cultivation claw 7 of the rotary cultivator R.
9 is pivotally supported by a rear cover suspension rod 26,
The pivot sensor 5 is provided with an angle sensor 4 for detecting the rotation angle of the rear cover 19.

In the tillage depth control of the rotary tillage device R, the angle sensor 4 detects the rotation angle of the rear cover 19 and sends the detected value as a signal from the transmitter 2 to the receiver 1 by a weak radio wave. The control circuit 6 connected to the receiver 1 by a signal with a weak radio wave automatically adjusts the tillage depth such as shallow tillage, deep tillage, etc. by the preset tillage claw 7 of the rotary tillage device R regardless of the unevenness of the field. This is performed by controlling the rotation of the lift arm 23 provided on the hydraulic device 21 and controlling the rotary tilling device R to move up and down so that the hydraulic device 21 is kept constant.

As described above, the control mechanism for the horizontal control and the plowing depth control of the rotary tilling device R mounted on the rear part of the tractor T uses the detection values of the inclination detection sensor 3 and the angle sensor 4 as signals from the transmitter 2. By transmitting to the receiver 1 by a weak radio wave and activating the control circuit 6 connected to the receiver 1, wireless communication by the radio wave is achieved.
The output of the radio wave transmitted from the transmitter 2 is configured to be adjustable according to the size of the working machine. In the present embodiment, the receiver 1 is provided on the tractor T main body and the transmitter 2 is provided on the working machine. However, the present invention is not limited to this. It is also possible to provide the receiver 1 with the receiver. In addition to such a structure using radio waves, a structure using ultrasonic waves instead of radio waves, or as shown in FIG. 2, a receiver 30 is arranged on a tractor T, and a rotary tilling device R as a working machine is used. A structure using optical communication by an optical communication device provided with the transmitter 31 or a structure using infrared light can also be used.

[Effects of the Invention] The present invention has the following effects because it is configured as described above. That is, by adopting a wireless structure using radio waves, wires, links and cords are not used, so that the performance of the working machine does not change and the performance of the working machine can be stabilized. In addition, since it is not necessary to attach and detach wires and cords simultaneously when attaching and detaching the work machine, it is possible to easily attach and detach the work machine, and to adjust the output of the transmitter provided in the work machine. Therefore, the transmitter can be widely used for working machines from large to small, and the transmitter can be shared.
