[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a self-propelled control machine for performing control work while reciprocating between the ridges while straddling the ridges.

[0002]

2. Description of the Related Art Conventionally, a self-propelled control machine is known, which is capable of controlling crops on both sides by traveling through ridges or controlling ridges from above to below one ridge. . An engine or an electric motor is mounted as a traveling drive device of these self-propelled control machines, and a hose winding device for feeding and winding the spray hose is mounted.

[0003]

However, in the conventional spraying method, it is not possible to spray the chemicals to the trees inside the ridge due to the degree of adhesion of the chemicals to the front and back surfaces of the leaves on the outer periphery of the ridge, and only the surface portion is sprayed. It was. Therefore, there is also a method of manually inserting a nozzle into the ridges and spraying the ridges, but this causes unevenness in the spraying of the chemicals, resulting in poor work efficiency.

[0004]

Means for Solving the Problems As means for solving the above problems, the present invention is an elevated self-propelled control machine that travels across a ridge, in which a spraying section is moved up and down on a machine body frame. Means, traveling drive means, means for detecting a constant traveling distance, and a control circuit connecting the elevating and lowering driving means, the traveling driving means and the detecting means are provided, and a spray nozzle is inserted into the ridge at every constant distance to control Configured to do.

[0005]

With this configuration, when the vehicle travels for a certain distance, the traveling is stopped, the spraying section descends, the spray nozzle is inserted into the crop on the ridges for control, and the spraying rises. After spraying is stopped and the vehicle is run again, the above process is repeated, and effective control is automatically performed against the pests attached to the trees inside the ridges.
