DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for spraying a chemical solution by means of a spray nozzle on a traveling chassis, and more particularly to a method for spraying a chemical solution while traveling along a ridge in a house, and a method for implementing the spraying method. It relates to a traveling sprayer.

[0002]

Conventionally, when spraying a chemical solution from a traveling chassis, the operator is present with the traveling chassis to steer the traveling chassis, so that the chemical solution is sprayed to the operator during the spraying operation. There is such a problem.

[0003]

SUMMARY OF THE INVENTION A spraying method and a self-propelled sprayer according to the present invention have been made in order to solve such a problem, and the traveling undercarriage is set in a predetermined direction by a winding force of a hose. By running, the operator can move away from the traveling platform, and there is no disaster of the operator due to the chemical solution, and the spraying operation in the house can be easily and safely performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
Referring to FIG. 1 is a side view showing a self-propelled sprayer, FIG. 2 is a front view of FIG. 1, FIG. 3 is a diagram showing a power transmission mechanism of FIG. 1, and FIG. It is a figure showing an example.

1 to 3, reference numeral 1 denotes an undercarriage in which a front wheel 1a is driven by three wheels including right and left wheels and a rear wheel 1b is a single wheel, 2 denotes an operation handle projecting backward from the undercarriage 1,
3 is an engine mounted on the rear of the chassis 1, 4 is a spray nozzle installed in front of the chassis 1, 5 is a hose winder installed on the chassis 1, 6 is a hose winder 5 which supplies the power of the engine 3 to the hose winder 5. The clutches A and 7 for transmission are connected to the spray nozzle 4 at the base end.
The hose 8 is connected to the hose winder 5 and is wound on the hose winder 5. Reference numeral 8 is a delivery guide of the hose 7 which moves integrally with the rear wheel 1b. Reference numeral 9 is located between the hose winder 5 and the delivery guide 8 and is rotated by the engine 3. The drive roller 10 of the hose 7 is the drive roller 9
A roller for pressing and releasing the hose 7 from the
11 is a switching lever for moving the roller 10 up and down, 12 is a clutch B provided on the drive roller 9 for transmitting this rotation to the front wheel 1a freely, and 13 is an overturning wheel mounted on the rear of the chassis 1 In this case, the rear wheel 1b is provided at a position slightly floating from the rear wheel 1b.

Next, a spraying method using the self-propelled spraying machine shown in FIGS. 1 to 3 (hereinafter, referred to as “the machine P” in this embodiment) will be described with reference to FIG. In FIG. 4, 14 is a house, 15 is a ridge in the house 14, 16 is a power sprayer outside the house 14, and 17 is a chemical tank.

In the house 14, the other end 7a of the hose 7 fed from the machine P is connected to the power sprayer 16 outside the house 14, and then the hose 7 is connected to the entrance of the ridge 15 into which the machine P enters. Then, the machine P is advanced to the innermost part of the ridgeway 15 while the hose 7 is extended as shown in the figure.

In the state shown in FIG. 4, the switching lever 11 is operated to press the hose 7 against the driving roller 9 by the roller 10, and the both clutches A6 and B12 are connected to drive the hose winder 5 and the front wheel 1a. After the state, the power of the engine 3 is transmitted and the operator goes out of the house 14.

Then, when the hose winder 5 starts winding the hose 7, and the hose 7 is tightened with the member 15a as a base, the machine P moves backward along the ridgeway 15 due to the hose winding force (see FIG. (In the direction of the middle arrow 18). At this time, the rotation of the driving roller 9 makes the winding of the hose 7 easy and smooth, and the rotation of the front wheel 1a makes the backward movement of the machine P smoother.

When the machine P moves backward in this manner, at the same time, a chemical solution is sent from the power sprayer 16 by the hose 7 and sprayed from the spray nozzle 4. That is, the chemical spray is performed together with the backward movement of the machine P. Then, when the machine P moves backward along the ridge 15, the backward running of the one rear wheel 1 b is stabilized by the fall prevention wheel 13, and the machine P does not fall down.

Since the machine P moves backward in the direction in which the hose 7 is tightened (that is, in the direction of the member 15a), the spraying operation by the machine P is possible even in a place where the ridge 15 is not provided. It is not limited to the house 14.

In the above embodiment, the undercarriage 1 is driven by three wheels. However, the vehicle may be driven by four wheels. In this case, the overturn prevention wheel 13 becomes unnecessary. In the above embodiment, the drive roller 9 assists the winding of the hose 7, and the front wheel 1a is driven at the time of reversing to assist the reversing of the machine P. However, these assists are appropriately selected depending on the application. Work.

[0013]

As described above, according to the present invention, the traveling chassis runs in a predetermined direction by the winding force of the hose, so that the operator can move away from the traveling chassis.
There is no effect on the operator due to the chemical solution, and the effect that the spraying operation in the house can be easily and safely performed can be obtained.
