Description

[Detailed Description of the Invention] The present invention relates to a drug dispersing machine for mixing liquid or powdered drugs in a drug tank into air blown by a fan and dispersing them.

Generally, in this type of chemical sprayer, the amount of chemical to be sprayed is adjusted by appropriately opening and closing a valve that adjusts the chemical, such as a shutter installed at the bottom of the chemical tank, but fine adjustment is difficult. A tuttle lever changes the rotational speed of the engine to adjust the amount of air being blown and the amount of chemical being sprayed.

Conventionally, this throttle lever was located on the rear left side of the worker carrying the chemical sprayer on his or her back, making it difficult to operate and causing the chemical sprayer to move as the throttle lever was operated, reducing stability. ,
Furthermore, the throttle lever had to be operated frequently during the spraying work, making the operation cumbersome and easily tiring. Another disadvantage was that the throttle lever was not in a visible position and was located at the rear of the body, making it prone to malfunction.

The present invention aims to provide an operator with a throttle lever close to the grip part of the air pipe that is held in the right hand during the spraying process, thereby making it easy to operate and without the risk of malfunction. It is something to do.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3, numeral 1 indicates a chemical sprayer, which is constructed as follows. That is, a fan case 3 houses a fan (not shown) rotated by an engine 5, and a drug tank 7 is fixed to the upper part of the fan case 3, which is supported by a support frame 9.
Reference numeral 11 denotes a backrest fixed to the support frame 9, which is placed on the back of the worker to carry the fan case 3, etc. on his or her back using a backpack band (not shown). 13 is a cylinder, 15 is a carburetor, 17 is a recoil starter, and 18 is a muffler. Reference numeral 19 denotes an air passage for guiding air from a fan (not shown), to which an air pipe 23 is connected via a flexible tube 21 . The blow pipe 23 is connected so as to be divided into a plurality of parts for convenient storage and transportation, and is provided with a spout 25 at the tip. Reference numeral 27 denotes a drug supply pipe for mixing the drug solution in the drug tank 7 into the air blowing in the air passage 19;
9 is provided. Reference numeral 31 denotes a grip portion fixed to the blower pipe 23, 33 a throttle lever pivotably attached to the grip portion 31, and 35 a throttle wire latched to the end of the throttle lever 33. , the other end is connected to a throttle valve (not shown) in the carburetor 15 to adjust the fuel supplied to the engine. 37 is throttle wire 3
This is the flexible outer tube of No. 5. 39 is throttle lever 3
A stopper 41 is a push button for electrically stopping the engine 1.

In the above embodiment, when a fan (not shown) is driven by the engine 1, the air is blown into the atmosphere through the air passage 19, the air pipe 23, and the air outlet 25. The chemical liquid in the drug tank 7 is controlled by a control valve 29,
The drug is mixed in during air blowing from the drug supply pipe 27 and is ejected from the spout 25.
dispersed into the atmosphere. The operator carries the chemical sprayer 1 on his back and grasps the grip 31 of the blower pipe 23 with his right hand to carry out the spraying work.To adjust the amount of chemical spray, he operates the throttle lever 33 as appropriate.
A throttle valve (not shown) is operated via a throttle wire 35 to adjust the rotational speed of the engine 5.

In addition, FIG. 4 shows another embodiment, in which the blower pipe 23 is located near the position where the worker holds it with his right hand.
A throttle lever 43 is provided.

Since the present invention has the configuration as described in the claims, it is possible to easily adjust the spraying agent, and there is no risk of malfunction, and the spraying work can be performed easily and smoothly. be.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well. Further, the symbols shown in the claims do not limit the technical scope of the present invention.
