The present invention relates to a self-propelled spraying device that moves to the next furrow.

[0002]

2. Description of the Related Art Conventionally, there is a known self-propelled dispersing vehicle which is mounted on a horizontal carriage and moves to the next ridge while performing a spraying operation of water or a chemical solution while reciprocating between ridges. The self-propelled spreader gets off from the horizontal carriage stopped on the runway of the ridge, travels forward while pulling the spray hose, is switched to reverse travel at the end of the ridge, and is automatically turned on by the hose winder. It is configured to return to the horizontal transport vehicle while winding up the spray hose, and to be mounted again, and the self-propelled spray vehicle is moved by the horizontal transport vehicle being pulled by a winch and moving on a track. , So that it can be conveyed horizontally to the entrance of the runway in the next ridge.

[0003]

However, in the above-mentioned prior art, the forward and backward traveling of the self-propelled spreader and the movement of the horizontal transport vehicle are not linked but performed separately. Therefore, when the operation of spreading the row of ridges by the self-propelled spreader ends, the lateral transport of the self-propelled spreader to the next ridge requires an operation by the operator each time. Therefore, an object of the present invention is to configure a self-propelled spraying vehicle that can automatically and easily perform a spraying operation and can cope with a spraying operation of a plurality of houses and the like. .

The spraying work can be performed in each of the houses H1, H2, and H3 only by tuning to the channels 1ch, 2ch, and 3ch. For example, when the spraying work is performed in the house H1, the other houses H2 and H3 are used. The self-propelled spreader S and the winch W can be prevented from malfunctioning. The dial-type switching channel 41 is additionally provided in FIG.
The push-button channel 42 shown in FIG. 3 is also possible, and is not particularly limited.

4 and 5, the spray hose 4 is pulled by a self-propelled spreader S or wound up by a hose winder A via a hose guide 20 provided on a horizontal transport trolley D. However, as shown in FIG. 6, when the pulling direction of the spray hose 4 and the wire 1 of the winch W are not located on a straight line, the force for shifting the horizontal transport vehicle D is used. Occurs. Therefore, the wire 1 corresponding to the hose guide 20 provided on the opposite side of the open portion of the mounting table 27 of the horizontal transport vehicle D
And the wire 1 is positioned in a straight line with the pulling direction of the spray hose 4,
The spray hose 4 and the wire 1 are balanced with each other, so that no force is generated to shift the horizontal carriage D.

As shown in FIG. 3, when a spraying operation is performed by disposing a self-propelled spreader S, a horizontal transport vehicle D, a winch W, etc. in the center of the house H ', the direction of the horizontal transport vehicle D is changed. When performing the spraying operation, wire guides 43 composed of pulleys and the like for guiding the wire 1 are disposed near the winch W at the end of the conveying rail 2 and sprayed through the wire guides 43. The hose 4 and the wire 1 are balanced with each other.
