DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating brush for a seedling box washing machine used in a seedling box washing machine capable of automatically washing a seedling box.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional rotary brush for a seedling box washing machine. A rotary brush 101 is provided with a cylindrical brush body 102 and a hair implanted at intervals in the circumferential direction of the brush body 102. A plurality of rows of brush bristles 103 and a brush body 10
Corner brush bristles 104a, 104b attached via metal fittings 105a, 105b between the brush bristles 103 at portions near both ends in the axial direction, respectively, and the corner brush bristles 104a, 104b
It is configured to have a forward angle theta ₁ to the rotational direction with respect to the axis C of the brush body 102 with having a tilt angle theta ₂ with respect to the peripheral surface 102a (see JP-real-Open No. 6-70540).

For this reason, the corner brush bristles 104a, 104 are rotated with the rotation of the rotating brush 101 rotating in the direction of the arrow.
b abuts on the opening edge 106a of the seedling box 106 and bends,
By entering the inner surface of the side wall 106b, the inner surface of the side wall 106b can be rubbed.

[0004]

[SUMMARY OF THE INVENTION However, in the conventional technique, since the corner portion bristles have a forward angle theta ₁ to the direction of rotation, the corner brush bristles to the opening edge portion of the seedling box as described above those When contacting and bending, there is a gap between the brush bristles and the brush bristles at the rear in the rotation direction. As a result, since the corner brush bristles themselves come into contact with the inner surface of the side wall of the seedling box only by the resilience thereof, the force of contact with the inner surface of the side wall becomes small, and poor cleaning occurs on the inner surface of the side wall of the seedling box. There is a point.

The present invention has been made in view of the above-mentioned problems of the prior art, and has been made to realize a rotating brush for a seedling box washing machine having an excellent ability to wash the inner wall surface of the seedling box. It is the purpose.

[0006]

In order to achieve the above-mentioned object, a rotating brush for a seedling box cleaning machine according to the present invention is provided with a cylindrical brush body and an interval therebetween along the peripheral surface of the brush body. In a rotating brush for a seedling box washer having a plurality of rows of vertical brush bristles extending in the axial direction, the bristles are disposed between the rows of the vertical brush bristles near both ends of the brush body. The tip of the bristles is provided with slanted brush bristles that protrude inclining outward in the axial direction.
To so that is supported by contact with the vertical bristles when flexed in contact with the opening edge portion of the seedling box, and overlapping with respect to the vertical brush bristles in the rotational direction front portion of the rotating brush It is characterized by being provided substantially parallel in a state.

[0007] Preferably, the angle of inclination of the inclined brush bristles with respect to the peripheral surface of the brush body is about 45 degrees.

[0008]

With the rotation of the rotating brush, the inclined brush bristles come into contact with the opening edge of the side wall of the seedling box and enter the inner surface of the side wall of the seedling box while being bent. It is supported in contact with the vertical brush bristles located on the side. As a result, the inclined brush bristles strongly contact the inner surface and the corners of the side wall of the seedling box, and rub against the inner surface, so that dirt attached to the inner surface of the side wall of the seedling box can be completely removed.

[0009]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic partial front view of an embodiment of a rotating brush for a seedling box washer according to the present invention.

The rotating brush 1 has a shaft 5 protruding from both ends.
, A plurality of rows of vertical brush bristles 3 provided at intervals along the peripheral surface of the brush cylinder 2, and both ends of the peripheral surface of the brush cylinder 2 The bristles provided between the rows of the vertical bristles 3 in the vicinity of the portion are provided with inclined bristles 4 whose tips are inclined and protruded outward in the axial direction .
2) when it comes into contact with the opening edge 11a and is bent.
Rotating brush 1 so that it is supported against brush bristles 3
Are provided substantially in parallel with the vertical brush bristles 3 in a portion on the front side in the rotation direction.

In the present invention, the inclination angle .theta. Of the inclined brush bristles 4 with respect to the peripheral surface of the brush body 2 can be changed as required. The cleaning ability of the corner 13 between the walls (see FIG. 2) is improved. The smaller the distance between the vertical brush bristles 3 and the inclined brush bristles 4 is, the better. However, if an interval of about 10 mm is provided, the flocking operation of the inclined brush bristles 4 can be easily performed.

Next, the operation of the rotating brush 1 for the seedling box cleaning machine of the present embodiment will be described.

As shown in FIG. 2, in the seedling box washing machine,
The rotating brush 1 is rotated in the direction of the arrow.

As the rotating brush 1 rotates in the direction of the arrow, the side of the inclined brush bristles 4 slides into the inner surface of the side wall 11 while being bent and deformed by contacting the front edge 11a of the side wall 11 of the seedling box 10. The inner surface of the side wall 11 is rubbed. At this time, the inclined brush bristles 4 deformed and deformed are brought into contact with and supported by the vertical brush bristles 3 located rearward in the rotation direction, and the inner surface of the side wall 11 of the seedling box 10 and It is strongly in contact with the corner 13 between the side wall 11 and the bottom wall 12. As a result, the inner surface of the side wall 11 and the side wall 11 and the bottom wall 12
Corner 13 of the above is sufficiently wiped.

[0016]

Since the present invention is configured as described above, the following effects can be obtained.

The inclined brush bristles abut the opening edge of the side wall of the seedling box as the rotating brush rotates, and rub against the inner surface of the side wall of the seedling box while flexing. Because it is supported by brush bristles, it is strongly abutted against the inner surface of the side wall of the seedling box and the corner between the side wall and the bottom wall, completely removing dirt on the inner surface of the side wall of the seedling box and the corner between the side wall and the bottom wall, which are difficult to remove. Can be dropped.
