Description

[Detailed explanation of the idea] The present invention relates to an improvement of a seedling box washer.

In recent years, the development of cleaning devices for seedling boxes has been progressing,
Conventional cleaning systems have mainly had brushes placed inside the tank that touch both sides of the seedling box, and cleaning can be carried out by moving the seedling box up and down.

For this reason, the water in the tank is easily contaminated with mud, and since the seedling boxes are washed with muddy water, finishing cleaning must be performed afterwards, and the tank interior has to be cleaned frequently, which is a hassle. There were many things to do.

The present invention was developed in response to these circumstances, and instead of using tanks at all as in the past, it uses the water from the irrigation canal that flows near the rice planting site, and uses a dam plate to do this. The seedling box is washed using water stored by damming the waterway or overflow water, and the seedling box can always be washed with clean water, which eliminates the final washing work, simplifies equipment, and improves work efficiency. It is something that I will try to plan.

The first embodiment will be explained with reference to FIGS. 1 and 2.
Reference numeral 1 denotes a dam plate made of wood, synthetic resin, etc., and auxiliary dam plates 2, which are shorter and of the same height, are arranged on both left and right sides of the dam plate 1.

There are several horizontal guide holes 3 in both auxiliary dam plates 2.
are provided, and tightening bolts 4 inserted through the left and right ends of the dam stop plate 1 are inserted through these, and both auxiliary dam stop plates 2 are fixed to the dam stop plate 1 by tightening the tighten bolts 4. They are connected, and the width can be adjusted by both dam plates 1 and 2.

One side of the dam plate 1 is provided with an elongated opening 5 for inserting a seedling box parallel to the surface of the dam plate 1 in the center of the upper surface, and each of the left, right and front surfaces are shaped like a frame. In addition, a cubic frame 6 having a structure in which the lower surface is completely open is installed, and inside this cubic frame 6 there is also a hole slightly longer than this elongated passage 5 parallel to the axial direction of the elongated passage 5. Two elongated brushes 7 are provided. The two elongated brushes 7 have their bristle tips facing each other and in contact with or close to each other so that the bristle tip surfaces are aligned below the central axis of the elongated opening 5.

In addition, a water inlet 8 for adjusting the water level is provided below the center of the dam plate 1, as shown in FIG. It is designed to be able to be raised and lowered.

FIG. 3 shows an example in which two parallel cylindrical rotating brushes 10 are provided in place of the elongated brush 7 described above.

Further, FIG. 4 shows an example in which the two elongated brushes 7 are provided perpendicularly to the plate surface of the dam plate 1,
The elongated passage 5 is also perpendicular to the dam plate surface, and accordingly, the cubic frame 6 also has a shape in which its longitudinal direction protrudes laterally as shown in the figure.

Next, to explain the cleaning action, as shown in Fig. 5, the irrigation canal 11 installed near the field
is dammed by adjusting the damming plate 1 and the auxiliary damming plate 2. At this time, depending on the flow direction of the water channel, water can be stored on the installation side of the cubic frame 6 or on the opposite side, but if the cubic frame 6
When the installation side is upstream and water is stored and the water is allowed to overflow to the opposite side, the water inlet 8 is opened and closed appropriately to adjust the water level to about the upper surface of the cubic frame 6.

5, the seedling box 12 is inserted through the elongated opening 5, both sides of the seedling box 12 are passed between the opposing elongated brushes 7, and the seedling box 12 is moved up and down to wash about half of the seedling box. Next, the seedling box is removed from the cubic frame 6, turned upside down, and the same operation as above is repeated to completely wash the seedling box.

In addition, when the installation side of the cubic frame 6 is located downstream, the upper edge of the dam plate 1 is washed in the same manner by the water flow flowing down, and in this case, the washing wastewater flows directly down. Therefore, the finish is better than the above case.

As described above, according to the present invention, seedling boxes can be cleaned using the water flow of irrigation canals flowing near the field, and in particular, young seedlings can be washed on the spot immediately after taking them out of the seedling box for rice planting. It has the feature of being washable,
In addition, since the cleaning device itself does not have a tank unlike conventional cleaning devices, it is convenient to carry and suitable for low-cost mass production, which has great practical effects.
