Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention is directed to a machine control device for an I■I transplanter that maintains and controls the left and right tilt of the machine on a rocky shore in a horizontal state. It is.

[Prior art] In the III transplanter, the machine body is supported on the surface by the two feet, and the machine body is propelled by the middle wheels that roll 11980. 11 Due to the traveling assistance, the aircraft was tilted up and down, left and right relative to the rice field due to shallow and shallow unevenness, and the seedling tank was moved sideways during the evening.
When approaching, the aircraft tends to lean left or right.

Therefore, in order to correct the tilt of the aircraft, conventionally a pair of 1 & ground sensors were installed that operated independently at symmetrical positions on the right (of the human body). Due to the pressure-sensitive difference in the ground pressure, the hydraulic system raises the running wheels and corrects the inclination in the direction of 1 to horizontal (hereinafter referred to as L). - called ring control), for example, Grand Duke 11r15
J is proposed in G-2811.

Also, in addition to the above-mentioned "1-ring control,); cross the medium flame of the body, lCL! Interflow-1~pff, J, and the aircraft's"
Detecting the ground pressure fluctuations caused by the movement, this ground contact 11
A method has already been proposed in which the traveling wheels are moved by a hydraulic system due to fluctuations so that the aircraft can be controlled up and down to a substantially constant level with respect to [0] (hereinafter referred to as level control). There is. ,' [Technical problem of the invention] In such a configuration (, the problem here is that when driving on the road 15 when turning at a headland, etc., ffl l+fi
- When lifting and moving, if the hydraulic mechanism for rolling control is working, the machine body will wobble from side to side, resulting in poor stability and inability to maintain a horizontal position. It is. There was also the problem that when the engine was stopped with the aircraft on its back, the aircraft would wobble from side to side due to oil leaking from the hydraulic mechanism.

[Object of the Invention] The present invention was proposed with the object of solving the following problems: 1. :b, so, for example, 1]-1 the body of the transplanter is raised to the Vk non-crop state.In J3, the hydraulic cylinder for 1"-ring control is in the non-leak state (adults remain as they are). By making it possible to maintain this position for a long period of time, it prevents the lB transplanter from wobbling when traveling on roads or turning, and also prevents the machine from tilting when handling oil by stopping the engine. happened 4
The purpose of this is to capture the aircraft control system of 1lfl tie l with just one person operating it.

1. This rolling control pulse is switched and controlled corresponding to the above-mentioned 1-ring control pulse 27 to correct the ring tilt. A switching harp 33 is installed in the oil passage for 11-ring control via 27, and during the calculated value f] operation, the switching pulp 33 controls the [''-ring control oil I'J] cylinder 32. In order to cover the formation of the 41 leakage condition, the above-mentioned 1, 7I replacement pulp 33/!: control means are used (i6).

(Embodiment) An embodiment of the present invention will be specifically described with reference to the drawings.
