Description

[Detailed description of the invention] [Industrial application field] The present invention carries a relatively small-capacity chemical liquid tank and transports it by means of transport wheels, and is used for small-scale standing trees for home and school use. The present invention relates to a chemical sprayer suitable for growing bonsai, flowers, vegetables, etc. and maintaining the growing state, and also suitable for use by professionals as necessary.

[Conventional technology]

This is a small chemical sprayer that applies pressure to the chemical solution in the chemical tank by hand using a handle installed on the piston rod, and uses that pressure to spray the chemical solution from the nozzle in order to kill insects, sterilize, replenish nutrients, etc. In the past, devices with a capacity of 9 liters of medicinal solution or less were used by carrying them on the shoulder (hereinafter referred to as shoulder type) or on the back (hereinafter referred to as backpack type). .

[Problem to be solved by the invention] In this type of shoulder type and tank type chemical liquid sprayers, the chemical tank and other parts to which the chemical liquid is attached come into direct or indirect contact with clothing or skin, and these become contaminated. Sometimes.

In particular, this tendency becomes more severe as the piston rod and tank guide wear out over a considerable period of use.

Furthermore, in both of the above types, when attempting to operate the handle during use, the piston rod tends to tilt, making it not only difficult to operate;
(For example, if the capacity of the chemical solution is 9 liters, the weight of the chemical solution is 9 kg, and if you include the tank and auxiliary equipment, the total weight will be approximately
12Kg or more) This is combined with the force of pushing down the handle and the effort of handling the hose.

Therefore, it is labor-intensive, may be unsuitable for use in some cases, and combined with the aforementioned contamination of clothing and skin, it is also psychologically undesirable.

Furthermore, as mentioned above, the piston rod is likely to be pushed down or pulled up to the left or right with respect to the cylinder, resulting in severe wear of the packing rings, etc.
It was difficult to use it for a long time.

On the other hand, when the chemical tank is placed on the ground and the handle is pushed down and pulled up, the user is forced to bend forward, which has the disadvantage of causing a lot of fatigue.

The present invention solves the above-mentioned problems of conventional chemical liquid sprayers, makes it easy to transport, and prevents contamination of clothes and skin.
Another object of the present invention is to provide a chemical liquid sprayer that allows easy operation of the handle of a chemical liquid tank for spraying chemical liquid, and can be used for a long period of time.

[Means to solve the problem]

The present invention relates to a means for a chemical liquid sprayer to achieve the above-mentioned object, and includes a pedestal on which a chemical liquid tank can be mounted and a transport wheel is attached, a lower end of a rising rod is attached to the pedestal, and the lower end of a rising rod is attached to the upper part of the pedestal. A pushing handle provided with a grip, a fixing means for fixing the chemical liquid tank mounted on the stand to the rising rod, and an upper part of the piston rod in the chemical liquid tank are attached, and a sliding ring slides up and down the rising rod. By providing an operating handle, this objective is achieved.

[Effect]

In the chemical liquid sprayer of the present invention, the chemical liquid tank is mounted on a pedestal, which is fixed to a rising rod with a fixing means, and the device is moved to an arbitrary location by conveying wheels by grasping the grip of the pushing handle at the top of the standing rod. and can be placed stably in that location.

Then, by pressing down the piston rod of the chemical tank, the chemical liquid in the tank is pressurized, and the chemical liquid is sprayed from the spray nozzle, and the chemical liquid can be sprayed on standing trees, bonsai, flowers, vegetables, etc. for insecticide, sterilization, and nutrient replenishment. It is something that

When pressing down the piston rod, the operating handle to which the piston rod is attached is guided by its sliding ring by the rising rod, so no tilting force is applied to the piston rod, which prevents wear of the packing ring, etc. It is.

〔Example〕

Next, an embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, the frame is composed of a base plate 1 and support plates 2 erected on the left and right sides thereof.
is rotatably mounted.

A grip 5b is formed on the upper part of the pushing handle 5, which has the right and left lower ends of the rising rod 5a attached to both sides of the support plate 2 by, for example, screws 6.

Screw holes 2a for screws 6 for attaching the rising rods 5a to the support plate 2 are provided in multiple rows on the support plate 2, front to back, top and bottom, and are attached to the support plate 2 depending on the size of the chemical solution tank 7, which will be described later. The position of the rising rod 5a can be adjusted.

Moreover, the chemical liquid tank 7 mounted on the base plate 1 is
It has the same shape and function as those conventionally known, and is removably mounted on the base plate 1.

That is, by moving back and forth with respect to the rising rod 5a,
A channel-shaped rod 8 that can be fixed in that position supports the back side of the chemical solution tank 7, and a band 9 having a buckle 9a provided on the rising rod 5a,
The front side of the chemical liquid tank 7 is supported and the chemical liquid tank 7 is fixed to the base plate 1 and the rising rod 5a.

Therefore, by removing the buckle 9a of the band 9, the chemical tank 7 can be lowered from the base plate 1.

The piston rod 11 of the chemical tank 7 is attached to the operating handle 10, which has a sliding ring 10a that can slide the left and right rising rods 5a up and down.By operating the operating handle 10 up and down, the piston rod 11 can be moved up and down. However, the chemical solution in the chemical solution tank 7 can be pressurized.

In this embodiment, an operating handle 10 is provided with a connecting rod 12 extending downward, and the upper part of a piston rod 11 is removably connected to it by a connecting mechanism 13.

This chemical sprayer can be moved to a desired location and stably placed on the base plate 1 by grasping the grip 5b of the pushing handle 5 and pushing or pulling the carrier wheel 4 while rotating. can.

While operating the operating handle 10 with one hand, the user grasps the spraying hose 7a with the other hand to spray the chemical solution.

Although the above is one embodiment of the present invention, the present invention is not limited thereto, and various modifications as described below can be made.

(1) Other than commercially available chemical tanks may be used.

(2) In the above case, the upper part of the piston rod 11 may be directly fixed to the operating handle 10 by welding means or the like.

(3) The upper part of the piston rod 11 may be removably connected to the operating handle 10 by a turnbuckle mechanism or the like.

[Effect of idea]

As mentioned above, this invention is easy to move to the required location and can be placed in a stable state at the location, so pressurization of the chemical tank can be performed stably. It is.

Further, it is also possible to spray the chemical solution while moving as necessary.

And unlike the conventional shoulder type and rear type, there is no need to carry it on your shoulders or back.
Fatigue can be significantly reduced, and it is also possible to reduce the risk of chemical solutions adhering to clothing or skin and contaminating them.

Furthermore, since the operating handle to which the piston rod is attached has a sliding ring that slides up and down on the rising rod, no tilting force is applied to the piston rod, and the operation handle moves correctly up and down in a straight line. This has the effect of reducing wear on the cylinder, piston rod, and tank guide, making it durable for long-term use.
