BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact speed sprayer without a chemical tank.

[0002]

2. Description of the Related Art A commonly used speed sprayer has a blowing tank in which a chemical tank, a liquid feed pump for feeding the chemical solution under pressure, and a plurality of nozzles for spraying the chemical solution are arranged on a self-propelled carriage. It is equipped with a blower, and while driving a liquid feed pump and a blower by an engine, a human is self-propelled and sprays a chemical liquid in the orchard.

This speed sprayer is suitable for controlling an orchard on a flat land with a relatively large area, but an orchard on a sloping land with a small area. For example, as shown in FIG. As shown in FIG. 9, in an orchard or the like where the trees are narrow and dense, it is not suitable because there are many dangers due to falls and maneuverability.

Therefore, by lowering the chemical solution tank on the ground to make it compact and using a caterpillar type self-propelled walking dolly, the above-mentioned orchard where the speed sprayer cannot enter or an orchard at a slope where there is a risk of lodging. A compact speed sprayer has been proposed that can control pests safely, reliably, easily and efficiently.

This type of compact speed sprayer is provided with an automatic hose winder connected to a liquid feed pump on the ground, and the hose is paid out or wound up from the automatic hose winder according to traveling. .

[0006]

In the conventional compact speed sprayer, the hose 1 is fed out from the right side surface of the carriage 2 as shown in FIG. 9 and wound up as shown in FIG. There is a problem that the hose 1 becomes an obstacle and it is very difficult to carry out the control work.

[0007] The present invention has been made to solve the above problems, Oite select a hose to the left and right sides of the carriage
It is an object of the present invention to obtain a small-sized speed sprayer in which the hose is not obstructed during traveling and the control work can be easily performed by deciding the direction and allowing it to be wound up.

[0008]

A small-sized speed sprayer according to the present invention is equipped with a hose winding / unwinding mechanism of an automatic hose winding machine so as to be rotatable on both left and right sides of a carriage.

[0009]

[Action] in this invention is, by Rukoto to turn the hose winding feeding mechanism, Oite the hose to the left and right sides of the truck
Since the direction can be selectively determined and wound up or unwound, the hose may be unwound or wound up on the side that does not interfere with traveling.

Embodiment 1 An embodiment of the present invention will be described with reference to FIGS. 1 is a side view, FIG. 2 is a plan view, FIG. 3 is a front view, FIG. 4 is a plan view with a cover removed, and FIG. 5 is a view seen from line V-V in FIG.
FIG. 6 is a schematic mechanism diagram, and the same or corresponding parts as those of the conventional device are designated by the same reference numerals and the description thereof will be omitted.

In the figure, 3 is a self-propelled caterpillar of a truck 2, 4 is a handle for a pedestrian of the truck 2, 5 is a cover of the truck 2, 6 is a circular outer circumference, and a plurality of wind direction adjustments are made at a wind outlet 6a inclined forward. A blower formed by arranging the plates 7, 8 is a plurality of chemical liquid jetting nozzles arranged between the wind direction adjusting plates 7 of the blower 6, 9 is an engine for driving the blower 6, and 10 is an engine 9 to V
An automatic hose winder driven through a belt 11, an intermediate shaft 12, a hose take-up clutch 13, and a chain 14, and a take-up drum 1 for a hose 1 connected to a liquid feed pump 15 on the ground.
0A and a branch pipe 10B that serves as a rotation shaft of the winding drum 10A.
A torque limiter 10C provided at one end of the branch pipe 10B and driven by the chain 14, and a branch pipe 10B.
A pipe 10D connected to the other end of the nozzle and communicating with the injection nozzle 8,
It is composed of a hose winding and feeding mechanism 10E. The hose winding / unwinding mechanism 10E includes a turning arm 10a rotatably supported on both ends of the branch pipe 10B, a return cam 10b for hose aligning and winding held between the turning arms 10a, and the return cam 10b. Driven chain 1
0c and.

Next, the operation will be described. When the engine 9 is driven, the blower 6 rotates to eject the wind from the air outlet 6a, and the winding drum 10A rotates to feed the hose 1. Therefore, as shown in FIG. 1 is delivered. Of course, the hose winding and feeding mechanism 10E
As shown in FIG. 6, the chain 10c is located at the right side of the carriage 2.
Is driven by the liquid feed pump 15, and the liquid chemical in the liquid chemical tank is supplied from the hose 1 to the branch pipe 1 of the winding drum 10A.
It is jetted out from the jet head 8 to the pipe 10D through 0B.

Next, when the direction of the carriage 2 is changed as shown in FIG. 10, the hose winding / unwinding mechanism 10E is rotated together with the hose 1 (in the direction shown by an arrow 17 in FIG. 5), and the hose 1 is moved to the previous position. On the contrary, the hose 1 is located on the left side of the trolley 2 and is wound on the winding drum 10A from the left side of the trolley 2, so that the hose 1 does not interfere with traveling.

Embodiment 2 In Embodiment 1 described above, the hose take-up and feed-out mechanism 10E has a structure in which the hose take-up and feed-out mechanism 10E can be turned to the left and right sides of the carriage 2.
Even if two hose winding / feeding mechanisms 10E are fixedly provided on the left and right sides of the carriage 2 as shown in FIG.
In FIG. 7, the arm 10d is fixed by being fitted into the branch pipe 10B, and the chain 10c can drive the return cams 10b on both sides, respectively.

[0015]

As described above, according to the invention], cleanup operations not to hose interfere during running by the hose according to this invention as taken unwinding winding defining a Oite selectively direction on both left and right sides of the carriage It is possible to obtain the effect that it can be easily performed.
