Description

[Detailed explanation of the device] (a) Industrial application field This device rotates a strainer housed in the body, which eliminates the situation where the chemical solution cannot be stirred even when the amount of the chemical solution is small, and it can be used until the end. This invention relates to a chemical tank for a small-volume sprayer that enables normal spraying.

(b) Prior art As an example of a chemical liquid tank of a small-volume sprayer that has been used in the past, as shown in Fig. 5, stirring blades 3 are installed near the lower end of a strainer 2 suspended and fixed in a body 1. The upper end of the stirring shaft 4 which is set and fixed to the stirring blade 3 and stands upright passes through the lid 5 which is placed on the upper end of the body 1, and the prime mover 6 is placed and fixed on the lid 5.
The chemical liquid 7 can be stirred by stirring blades 3 which are connected directly to an electric motor (in this case, an electric motor) or through a speed reducer (not shown) and rotated by the drive of the prime mover 6.

(c) Problems to be solved by the invention In the chemical liquid tank configured as described above, since the stirring blades 3 are set further inside the strainer 2 housed in the body 1, The bottom part 2' of the strainer 2 is interposed between the bottom part 1' and the stirring blade 3, so that the stirring blade 3
When the chemical liquid 7 is stirred by rotation, a gap 8 must exist between the bottom portion 2' of the strainer 2 and the stirring blade 3 to allow the chemical liquid 7 to flow. As the chemical solution 7 in the body 1 is sucked into the suction pipe 9 and sprayed onto a desired area from a nozzle (not shown),
The amount gradually decreases, and when the spraying is nearing completion and the surface of the chemical solution 7 falls below the lower end of the stirring blade 3, it becomes impossible to stir the chemical solution 7, and as a result,
There is a problem in that the chemical solution 7 is precipitated, and this precipitate causes clogging of the chemical pipes and nozzles, making spraying extremely difficult or, in severe cases, impossible.

This idea was proposed by focusing on the above-mentioned drawbacks, and its purpose is to make it possible to stir the medicinal solution even when the amount of medicinal solution in the body becomes small, and to maintain the entire amount at a uniform concentration. The purpose is to provide a chemical solution tank for a small amount sprayer that can be used for spraying.

(d) Means for solving the problem In order to achieve the above-mentioned purpose, the chemical solution tank of the small amount sprayer according to this invention has a strainer housed in the body from which the agitation shaft protrudes inward. A strainer supported and suspended from a rotating shaft is equipped with an abutment and/or stirring blades,
The strainer is rotated by contacting the stirring blade with the relevant joint or by engaging with the stirring shaft to stir the chemical liquid in the body.

(e) Effect In this device, the strainer is rotated within the body by engaging the stirring blade attached to the stirring shaft with the abutment on the strainer side, or by rotating the strainer attached to the stirring shaft within the body. There is no sedimentation or residue at the bottom, and all chemical solutions can be sprayed at a uniform concentration.
