Description

[Detailed description of the invention] [Industrial application field] The present invention is applied to a fertilizer supplying device installed in a rice transplanter, etc., and in particular to a fertilizer supply route from the fertilizer delivery case to the fertilizer supply hose and into the furrower. Regarding cleaning tools.

[Conventional technology]

This type of cleaning tool generally includes a brush provided at one end of a rod-shaped member that can be inserted into the furrower through the fertilizer dispensing case.

[Problem that the invention attempts to solve]

In the case of this conventional cleaning tool, the fertilizer adhering to the inner wall of the case and the inner circumferential surface of the hose is scraped off only by reciprocating sliding of the brush, so that a thin layer of fertilizer is left on the inner circumferential surface of the case and the inner circumferential surface of the hose. It tends to remain, and even more so, the water cannot be removed. Therefore, there is a problem in that such residual adhering fertilizer and moisture make it easy for the fertilizer to adhere again in a short period of time.

An object of the present invention is to improve the above-mentioned conventional problems by a simple and inexpensive modification of the rod-shaped member provided with a brush.

[Means for solving problems]

The characteristic configuration of the cleaning tool for fertilization equipment according to the present invention is as follows:
A brush is provided on one side of a rod-shaped member that can be inserted from the fertilizer feeding case of the fertilizer application device into the furrower through the fertilizer supply hose, and a brush is provided on the other side of the rod-shaped member that is in close contact with the inner peripheral surface of the hose. The point is that an elastic brim-shaped body having a diameter sufficient for sliding contact is provided, and its functions and effects are as follows.

[Effect]

When cleaning the fertilizer supply route from the fertilizer dispensing case to the inside of the furrower through the fertilizer supply hose, first insert the brush first, and the reciprocating movement of this brush will clean the inner wall of the case and the inner peripheral surface of the hose. Scrape off any adhering fertilizer. Thereafter, the rod-like member is further pushed in or reversed, and the elastic brim-like body is moved in sliding contact with the inner wall of the case and the inner circumferential surface of the hose, so that it is attached to the inner wall of the case and the inner circumferential surface of the hose. It is possible to remove not only the thin layer of fertilizer but also the moisture that causes such adhesion.

[Effect of idea]

Therefore, a simple and inexpensive modification of simply providing brushes and elastic flanges on both sides of the rod-shaped member can be used.
The fertilizer supply route can now be cleaned reliably and easily.
