Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of a washer for seedling boxes.

[Conventional technology and problems]

A washer has been developed to wash away soil adhering to seedling boxes. This type of container has a seedling box insertion opening with a rectangular planar shape on the top surface of the cubic container, and the inner upper side of the container has a pad that slides into contact with the front and back surfaces of the seedling box, as shown in Figure 1. Large thick (height) brushes are placed facing each other, and brushes that slide against the side edges of the seedling box are also placed facing each other. What to do is
When inserting a seedling box and moving up and down for cleaning, the bristles of the brush bend to follow the direction of movement of the seedling box, as shown in Figure 1, and then resist the drag force of the bristles in this state. In order to move the seedling box to the opposite side, a large amount of resistance is generated, which requires labor and reduces cleaning efficiency.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and has a simple structure that eliminates the drawbacks of the conventional system, reasonably reduces the vertical movement resistance of the seedling box, and enables easy cleaning. labor saving, and
The aim is to improve cleaning efficiency.

[Structure of the idea]

The structure of the present invention that solves the problems of the conventional technology is as follows:
In a washer for a seedling box, which has a seedling box insertion opening formed on the top surface of the container, and brushes that are in sliding contact with the inner and outer peripheral surfaces of the seedling box are arranged on the left and right sides of the upper inside of the container, the front and back plate surfaces of the seedling box are cleaned. The bristles of both brushes that come into sliding contact with the brush have a semi-cylindrical shape (semi-cylindrical shape).

〔Example〕

To explain the details of the embodiment with reference to the drawings, 1 is a cubic container, and on the top surface of the container 1,
A cover plate 3 having an insertion opening 2 having a rectangular planar shape formed in the center thereof is removably attached with bolts 4 or the like. A brush holding plate 5 is vertically fixed to the lower surface of the cover plate 3 so as to largely surround the insertion opening 2.
The long side of the insertion opening 2 of the brush holding plate 5, that is,
As shown in FIGS. 3 and 4, long brushes 7 are attached to the sides of the seedling box 6 facing the front and back plates, and the bristles of both brushes 7 have a semi-cylindrical shape as shown in FIG. (semi-cylindrical shape) and make sure that the centers of the tips touch each other. Also, the short side of insertion port 2,
That is, on the side facing the side edge of the seedling box 6, a short brush 8 is provided below the long brush 7, as shown in FIG.

The brush holding plate 5 and the brushes 7, 8 are separated from the container 1 together with the lid plate 3. In addition, 9 shown in Figures 2 and 3 is
provided along the longitudinal axis direction of the insertion port 2,
The regulating plate 9 is a relatively wide regulating plate formed approximately equal to the entire inner width of the container 1 and having both edges downwardly inclined, and has a predetermined height at both ends. Also, the support frame 10 has approximately the same length as the inner width of the container 1.
are provided orthogonally, and both ends of the regulating plate 9 are fixed to the upper side of the support frame 10, respectively.

The regulation plate 9 attached to the support frame 10 is adapted to be taken out of the container. An upward brush 11 is attached to the entire length of the upper surface of the regulating plate 9, and the insertion opening 2 is attached to the surface of this brush 11.
The brush 1 on the upper surface of the cover plate 3 and the regulating plate 9 washes the outer surface of the short side of the seedling box 6 inserted from the top surface of the cover plate 3 and the brush 1 on the regulating plate 9.
The distance from the top surface of the seedling box 1 to the top surface of the container 1 is set to be slightly shorter than the length of the long side of the seedling box 6 to prevent the seedling box 6 from sinking into the container 1 and to prevent mud between the regulating plate 9 and the bottom of the container 1. A precipitate portion 12 is formed. Due to this relationship,
The condition is that the regulating plate 9 is located directly below the insertion port 2 as shown in FIG. Also, the reason why the long side direction of the insertion port 2 and the long side direction of the regulating plate 9 are made to match is that the flow of water generated when the seedling box 6 is lowered is in the direction of the arrow in Fig. 3, and the soil in the water is muddy and settled. This is to allow the seedlings to be accumulated effectively in the section 12 and to prevent backflow when the seedling box 6 is moved up.

Further, as shown in FIGS. 2 to 4, grooves 14 and 15 are formed on the upper and lower edges of the base plate 13 of the brushes 7 and 8, and the lower groove 14 is formed on the flange 16 formed on the brush holding plate 5. Fits into the protrusion 17, and
An engaging hook 18 made of a spring material attached to the flange holding plate 5 is fitted into the upper concave groove 15 with pressure, so that the brushes 7 and 8 can be easily attached to and removed from the brush holding plate 5.

[Effect]

Next, the cleaning action will be explained. As shown in FIG. 4, when the seedling box 6 is inserted between the brushes 7 at a certain angle, the bristles of the brushes change as shown in the figure. If you try to pull up the seedling box 6 in this state, you will encounter a resistance force, although it is smaller than conventional ones, so if you insert the seedling box 6 as shown by the solid line in the figure and rotate it in the direction shown by the imaginary line, the hairs will curve downward. On the contrary, the direction is upward. As a result, the seedling box 6 can be easily pulled up. After repeating this operation, the seedling box 6 is removed from the container 1, turned upside down, and the same operation is performed again to clean the seedling box 6.

[Effect of idea]

In this way, in the present invention, the bristles of the main long brush have a semi-cylindrical shape (semi-cylindrical shape) and are butted from the left and right sides. Not only does it not receive a large sliding resistance force, but as is clear from Figure 4, by reversing the insertion angle of the object to be washed, such as a seedling box, in the front-back direction, the curvature of the bristles can be reduced. It is possible to change the direction from downward to upward, or vice versa, and therefore the object to be cleaned can be moved up and down easily, which has great practical effects such as rational improvement of cleaning efficiency and labor saving. It is.
