Description

[Detailed Description of the Invention] This invention relates to a strainer cleaning device that makes it possible to remove foreign matter adhering to the mesh of the strainer by ejecting liquid from a pump onto the mesh of the strainer.

Conventional agricultural strainers, for example, use liquid chemicals, water, etc., so foreign substances such as liquid, dust, gravel, pebbles, etc. adhere to the mesh of the strainer, resulting in a decrease in the suction performance of the strainer. In particular, when thickeners are used, adhesion to the mesh is particularly severe.

Therefore, when removing the foreign matter, it is necessary to perform complicated operations such as swinging the strainer itself back and forth, left and right, or taking out the strainer from its setting location.

Further, when the strainer is incorporated into a device such as a speed sprayer, it is even more difficult to remove foreign substances.

Therefore, this invention provides a strainer cleaning device that corrects the above-mentioned drawbacks, and can easily, quickly, and reliably remove foreign matter adhering to the screen.Moreover, it has a simple structure and can be manufactured in a small size. It is designed to be easily transported, stored, etc.

An embodiment of this invention will be described below with reference to the drawings. The vertical frame 1, the upper frame 2, and the lower frame 3 of the main body B, which are integrally formed in a suitable shape, for example, a hexagonal shape, are made of synthetic resin or the like, and are connected to each other. While drilling through holes C5d and e that communicate with each other, a net n is stretched inside the vertical frame 1 in the vertical direction and inside the bottom frame 3 over the bottom surface, and each of the through holes c, d, and e is Each of the jet ports j, which are communicated at a proper location, is opened toward the mesh n.

In addition, the other end of the hose 4, which has one end connected to a suitable position in the through hole d of the upper frame 2, is connected to the output side of the pump Pα via a cock 5, while a retaining plate 6 stretched inside the upper frame 2 is connected to the other end of the hose 4. Suction tube S in the center
The lower end of the strainer is made to penetrate and protrude, so that the liquid medicine, water, etc. sucked into the inside of the main body B of the strainer can be sucked.

In the figure, a represents a spray object such as a chemical solution or water.

Since this invention has the above-mentioned configuration, the main body B of the strainer is placed in a predetermined place, for example, in a liquid storage tank (not shown).
The liquid in the liquid storage tank is sucked in through the suction pipe S and supplied to the desired point.

However, if the suction performance deteriorates due to liquid, dust, gravel, pebbles, or other foreign matter adhering to the mesh n, the cock 5 is opened and the pressurized liquid from the pump P side is pumped through the hose 4. Through holes c, d
.

According to this invention, when foreign matter adheres to the screen and causes a decrease in suction performance, the foreign matter is dropped in the appropriate place on the frame of the strainer, and pressurized liquid is ejected from the spout opening toward the screen. This allows foreign matter to be easily, quickly, and reliably removed from the screen, eliminating the tedious work of shaking the strainer to shake it off, or taking the strainer out of its setting to remove the foreign matter. The main body has a vertical frame,
Since the upper frame and the lower frame are integrally formed, there is no risk of the structure itself becoming complicated, and it can be made smaller, so it can be manufactured at low cost, and it is easy to handle when transporting, storing, etc.
Moreover, since the through holes are drilled in each of the vertical frame, upper frame, and lower frame, there is no fear of damage due to contact with foreign objects, and furthermore, there is no risk of damage from contact with foreign objects. The net has practical benefits such as not being constantly clogged due to the jet stream.
