DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved and means to be solved by the present invention are as described above. Next, the specific structure of the present invention will be described with reference to the accompanying drawings. 1 is an overall side view of a traveling sprayer, FIG. 2 is a front view thereof, FIG. 3 is a perspective view showing a working state of the traveling sprayer, FIG. 4 is a plan view thereof, and FIG. 5 is a traveling sprayer of the present invention. FIG. 6 is a diagram showing the relationship between the traveling speed of a car and the length of a spray hose, FIG. 6 is a front view of the traveling type spraying vehicle of the present invention when the vehicle width is widened, and FIG. It is.

Referring to FIGS. 1 and 2, the construction of the traveling type spreader will be described. The traveling spreader A is supported by traveling wheels 4, 4..., And a driving motor 5 is driven by electric power supplied from batteries 6, 6 provided in the cover. A spray nozzle 3 supported by a nozzle holder 7 is provided upright at the front of the vehicle body, and a front bumper 8 and a hose guide roller 9 are arranged below the spray nozzle 3. An operation panel 10 is provided at the upper center of the vehicle body.
A control box 11 is built in underneath.
At the rear of the vehicle body, a rear bumper 12 and a handlebar 13 are provided upright from below.

As shown in FIGS. 3 and 4, the traveling type spreader A is
While reciprocating on the runway between the furrows, the chemical solution (or water) in the tank C, which has been absorbed and pressurized by the dynamic jet 2 of the base machine B, is erected at the front of the traveling sprayer A via the spraying hose 1. It is sprayed from the spray nozzle 3 installed in the gardening house or the vegetable field of ridge cultivation.

Specifically, the operator starts the engine E of the base machine B, sets the changeover switch of the hose winder D attached to the base machine B to the automatic position, and sets the cock of the dynamic injection 2 to the open position. When the power switch on the operation panel 10 of the traveling spreader A is turned on and the start switch is turned on, the control circuit in the control box 11 is started. Then, according to the control of the control circuit, the traveling sprayer A automatically sprays from the spraying nozzle 3 and adjusts the spraying amount before entering the running path between the ridges. At this time, the clutch of the hose winder D of the base machine B is OFF, so that the spraying hose 1 can be sequentially fed out as the traveling spreader A advances.

[0010] The traveling spreader A is positioned on the runway between the furrows,
When the work start switch is turned on, the spraying starts, the advancing continues while spraying, and when the front bumper 8 comes into contact with the reversing stake 19, the traveling spreader A stops by the control of the control circuit in the control box 11. At the same time, the spray nozzle 3 also stops spraying. After a lapse of a certain time thereafter, the traveling sprayer A starts moving backward.

Next, when the traveling spreader A moves backward to the end of the ridge, the rear bumper 12 comes into contact with the hose guide pile 18, and the traveling spreader A stops. Then, the operator moves the traveling type spreader A to the next furrow and spreads the spraying hose 1.
Is hooked on the hose guide pile 18, and the same operation as described above is repeated.

By the way, as the traveling spreader A advances, the spraying hose 1 is sequentially drawn out from the hose winding machine D of the base machine B, and is pulled by the traveling spreader A. The longer the scatter hose 1
Because the liquid medicine is clogged, the weight of the liquid medicine becomes considerable, and the load on the drive motor 5 increases as the distance from the base machine B increases, the speed decreases, and the amount of spraying the liquid medicine increases. Therefore, in the present invention, the control circuit in the control box 11 controls the power supplied from the batteries 6 or controls the transmission by providing a continuously variable transmission on the output shaft of the drive motor 5. As a result, as shown in the graph of FIG. 5, when the traveling speed of the traveling sprayer is S and the length of the spraying hose is L, when the length of the dispensed hose 1 reaches a predetermined length. , Automatically increase the supply voltage from the battery 6.6,
The rotation speed of the motor 5 is increased so that the traveling speed S of the traveling sprayer A is kept substantially constant. In addition to supplying power in accordance with the length of the spraying hose, the traveling load is detected and the speed is increased when a predetermined load is reached. A constant speed is also possible.

Next, mounting the traveling wheel on the wheel boss
Shift the position and adjust the vehicle width in two stages by 180-degree inversion mounting.
A configuration that can be changed will be described. The width of the runway between the ridges on which the traveling spreader A travels during the spraying operation may be smaller than the vehicle width of the traveling spreader A in some places. So book
In the embodiment , as shown in FIG. 6, the wheels 16 and 16 of the tires 17 and 17 are arranged so as to be shifted from the center of the boss 16a, and the boss 16a is protruded from the lower part of the vehicle body of the traveling spreader A. Bolts 15
The traveling wheels 4 are formed by fixing at the positions shown in FIGS. 6A and 6B in the case of a wide ridge and FIG. 7 in the case of a narrow ridge.
, Remove the bolts 15
