Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a chemical solution storage device for a chemical spraying pest control machine that is capable of dispersing chemicals by putting powder, granular, and liquid chemicals into a chemical tank.

[Conventional technology]

Conventionally, as seen in Japanese Utility Model Publication No. 58-27785, in a chemical spraying pest control machine equipped with a chemical tank having a powder discharge device and a chemical liquid discharge port on the lower side, when spraying a chemical liquid, it is necessary to The powder device must be removed and the mist device installed.
Even so, there were problems in that liquid leakage occurred from the mist device and the reliability of liquid tightness was lacking.

[Problem that the invention attempts to solve]

The present invention solves such problems by storing the drug solution in a bottomed drug bag that can be easily loaded into the drug tank without removing the powder granulation device as in the past. Therefore, it is possible to reliably spray a chemical solution without causing liquid leakage, and to provide a simple structure that can be suitably implemented.

[Means for solving problems]

Therefore, in the present invention, a flexible drug solution bag made of vinyl or the like with a bottom can be inserted into and taken out from inside the drug tank, and the upper end opening of the drug solution bag can be freely locked to the upper supply port side of the drug tank. The chemical liquid pipe extending from the chemical liquid discharge port is connected to the inside of the chemical liquid bag.

[Effect]

Therefore, when spraying powdered or granular chemicals, if you close the chemical liquid discharge port as in the past, you can put the chemical directly into the chemical tank and spray it. When spraying, insert a chemical bag into the chemical tank and connect the chemical pipe to the chemical bag, so that the chemical liquid put in the chemical tank can be stored in the chemical bag without leaking and can be used. .

〔Example〕

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

Figure 2 shows a front view of the entire pest control machine, in which a chemical tank A is connected to the upper side of a blower C driven by an engine E, and a bent pipe 6 and a flexible tube 7 are connected to the blowing side of the blower C. An air branch pipe 8 communicating with the blower C and a drug pneumatic feed pipe 9 are connected to the powder discharge device 1 installed in the lower part of the inside of the drug tank A. A medicinal liquid discharge port 2 formed in the tank A is installed so as to be able to be closed by screwing the canal body 10 therein, and a cap 12 with a handle 11 is screwed into the supply port 4 formed in the upper part of the drug tank A. It is constructed in the same way as the shape and structure.

A connecting body 1 is removably screwed into the chemical liquid discharge port 2, and a chemical liquid pipe 5 extending from the connecting body 13 is extended to the dispersion pipe on the distal end side of the reversible tube 7, and a ventilation hole is provided on the upper surface. A strainer 15 that can be locked inside the cap 12 having a strainer 14 is removably fitted into the supply port 4, and a retaining ring 17 can be engaged with a circumferential groove 16 formed on the intermediate outer periphery of the strainer 15. be installed and configured.

B is a flexible, thin, bottomed drug solution bag made of vinyl or the like, and has a protruding opening 18 formed on the lower side and an upper end opening 3 on the upper side. It can also be formed by pinching out the lower side of a plastic garbage bag and cutting the tip.

FIG. 5 shows another embodiment, in which the bottomed chemical solution bag B does not have the protruding opening 3 as in the previous embodiment, but only the upper end opening 3, and the strainer 15
A hole 19 is formed in the upper part of the circumferential groove 16, and a hole 19' is formed in the bottom of the strainer 15. Opening at the tip 5
It is constructed by forming it as long as a.

Therefore, when dispersing powder or granules of chemicals, as shown in Figure 3, a stopper 1 is inserted into the chemical solution outlet 2.
9 and put powder or granule medicine into the medicine tank A from the supply port 4 and cover the cap 12, the medicine will be sent out from the discharging powder device 1 below, as in the conventional case. This means that chemical spraying can be performed.

In addition, when spraying a chemical solution, as shown in FIG. At the same time, it is locked inside the connecting body 13 so as to communicate with the chemical liquid pipe 5, and the upper end opening 3 of the chemical liquid bag B is fitted into the outer periphery of the same groove 16 of the strainer 15, and the retaining ring 17 is inserted from the outer periphery. When the strainer 15 is fitted and locked into the supply port 4, the drug solution bag B can be installed in the drug tank A without removing the powder discharge device 1.

When the drug solution is supplied through the strainer 15, the drug solution bag B comes into contact with the inner surface of the drug tank A and expands, so that the drug solution can be stored.
When the work is carried out with the cap 12 having the cap 4 attached, the chemical liquid is sent out from the chemical liquid pipe 5 without leaking, and the chemical liquid can be sprayed and sprayed in the same way as in the conventional method.

In the case of another embodiment shown in FIG. 5, the chemical liquid pipe 5 charged from the chemical liquid discharge port 2 is inserted into the holes 19, 19' of the strainer 15, and the tip opening 5a is inserted into the strainer 15.
The chemical solution bag B is attached so that it reaches the inner bottom of the drug solution bag B, and the drug solution can be stored in the drug solution bag B and sprayed out in the same way as described above.

[Effect of idea]

In this way, with the present invention, when spraying powdered chemicals, it is possible to do so by placing them in the chemical tank A in the same way as before, and when spraying liquid chemicals, the chemical solution bag B with a bottom can be installed in the chemical tank A. By storing the medicinal solution in this medicinal solution bag B, it becomes possible to spray the medicinal solution well with reliable liquid tightness without removing the powder discharge device 1 and without causing any liquid leakage. Since the bottomed drug solution bag B is made of flexible material such as vinyl, it is easy to put it in and take it out of the drug tank A, the storage condition is good as it is the same as the tank capacity, and even if it is damaged, it can be easily replaced. It has the advantage of being able to be suitably implemented with a simple structure.
