Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pest control machine that can be stationary or carried on one's back for pest control work, and can also be moved on wheels.

[Conventional technology]

This type of pest control machine was either a mobile type that could be stationary for pest control work, or a type that could be moved around on wheels, or a type that could be carried on the back for pest control work.

[Problem that the invention attempts to solve]

However, stationary and mobile types are difficult to move and work with, especially in mountainous areas.
In addition, backpack-type devices have the problem that workers will become excessively fatigued if they move and work while carrying them on their backs.

[Means for solving problems]

This invention solves these problems and makes it possible to easily operate the throttle lever depending on whether the person is carried on his back or stationary.For this purpose, a back rest and a shoulder strap are connected to the front standing side. The lower part of the support frame is equipped with an engine and a pump, and the upper part thereof is equipped with a drug tank, the lower part of the support frame is equipped with both wheels and a stand, and the front side of the support frame is equipped with at least one of the backrests. The handle can be moved from the upper side to the lower lateral side and has a throttle lever on the tip side, which is connected to the handle so that it can be moved and fixed at will.

[Effect]

Therefore, by positioning the handle above the backrest, when moving the machine, you can hold the handle and use both wheels to move the machine better, and work by keeping both wheels and the stand in a stationary position. If the operator is carrying the work while carrying the handle on his or her back, the throttle lever will be in the upper position, making it easier to operate.Also, if the operator is carrying the work on his or her back, moving the handle to the lower side of the backrest will allow the operator to move the throttle lever to the upper position. This means that it can be easily operated at hand.

〔Example〕

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the dynamic jet type pest control machine, in which a back support 1 is stretched on the front side of a raised part 3a which is formed upright at the front part of the support frame 3, and a connection is made at the center of the upper part of the raised part 3a. Shoulder bands 2 are attached to the metal fittings 10 and connecting metal fittings 11a and 11b on both sides of the lower part of the standing portion 3a.
The upper and lower ends of a and 2b are connected respectively, and a standing portion 3a is formed.
The horizontal lower part 3 of the support frame 3 extends rearward from the lower part of the support frame 3.
An engine 4 and a plunger type pump 12 are disposed above the engine 4, and a drug tank 5 having a lid 5a on the upper part is disposed above the engine 4, and the plunger type pump 12 is driven by the engine 4. A spray pipe 14 is connected via a hose 13 to a plunger type pump 12 that communicates with a drug tank 5.
are configured by connecting them in series.

Further, both wheels 6a, 6 are provided on both sides of the lower part of the horizontal lower part 3b of the support frame 3 approaching the backrest 1 side.
b are coaxially mounted, and the horizontal lower part 3
A narrow stand 7 is extended diagonally downward from the rear of the aircraft, and when both wheels 6a, 6b and the stand 7 are in contact with the ground, the center of gravity of the aircraft is located vertically downward between them, and the back The abutment 1 is installed and configured so that it is tilted backward.

A holder 15 is fixed to one side of the upper part of the upright portion 3a of the support frame 3, and a support shaft 17 projecting from the support pipe 16 in an orthogonal direction is fitted so as to be rotatable about the axis of the holder 15. The other end of the handle 9, which is bent into an L shape and equipped with a grip 9a and a throttle lever 8 at its tip, is centered around the axis of the support pipe 16. It is configured so that it can be rotatably inserted and fixed with a set bolt 19.

Note that when the other end of the handle 9 is attached to the center of the upper end of the upright portion 3a of the support frame 3 in the width direction, and the handle 9 is moved downward, it will be located at the lower lateral side of the backrest 1. It can also be installed and configured.

Therefore, as shown in FIG.
When carrying out pest control work with the aircraft in a stable position by grounding a, 6b and the stand 7, it is recommended to raise the handle 9 forward and above the backrest 1 and tighten the set bolts 18 and 19. The lever 8 is raised upwards and can be easily operated, and when storing the aircraft in a stationary position, loosen the set bolt 19 and center the handle 9 on the axis of the support pipe 16. 180 degrees to
Rotate it and tighten the set bolt 19.
As shown by the imaginary line in FIG. 1, the handle 9 can be stored on the rearward and upper side of the body.

Also, as shown in FIG. 1, if the handle 9 is set above the back rest 1, the handle 9 can be pushed down to tilt the machine slightly forward, and both wheels 6a,
6b allows it to be transported while being moved.

When carrying out pest control work while carried on the worker's back,
Loosen the set bolt 18, rotate the handle 9 about the support shaft 17 so that the grip 9a and throttle lever 8 are on the side of the backrest 1, and tighten the set bolt 18, as shown in Fig. 4. As shown, an operator who carries the machine on his back with both shoulder straps 2a and 2b on his shoulders can operate the throttle lever 8 while holding the spray pipe 14 with one hand and gripping the grip 9a with the other hand.

In addition, loosen the set bolt 19 and tighten the handle 9.
When slid in the axial direction with respect to the support pipe 16,
The handle 9 can be adjusted up and down, making it possible to adjust it to suit the physique of the operator.

[Effect of idea]

In this way, the present invention allows the user to hold the handle 9 and move it easily using the wheels 6a and 6b, and also to carry out pest control work conveniently and conveniently even when stationary or carrying it on one's back. 9 together with throttle lever 8
This means that it can be easily operated by placing it in the upper position.
In addition, when carrying out work while carrying the worker on his or her back, the throttle lever 8 is located close to the worker's hand together with the handle 9, making it possible to operate the hand easily and reliably, resulting in good operability and a simple structure. It has the feature that it can be carried out suitably.
