Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention is a flexible seedling frame (instead of a conventional rigid seedling frame) that is used in a transplanter and is equipped with a large number of pot-shaped seedling chambers.
This invention was filed by the present applicant and has already been published as Utility Model Publication No. 56-34247), and relates to an apparatus for efficiently (effectively) cleaning.

(Conventional technology and problems) After seedlings are transplanted, the seedling frame is covered with fine roots and muddy soil, so it needs to be cleaned. For this reason, various types of seedling frame cleaning devices have been proposed.
23 etc.). These cleaning devices lack workability because the seedling frame insertion port and discharge port are installed on opposite sides.

Further, since only one brush is provided for each side of the seedling frame, cleaning efficiency is lacking. If this were configured to abut at multiple locations, the structure would become complicated and impractical.

(Means for Solving the Problems) The present invention makes maximum use of the characteristics of the flexible seedling frame. That is, a curved passage is provided in a housing in which the insertion port and the discharge port are opened on the same side so that the flexible seedling frame can be reversed and transferred from the insertion port to the discharge port, and the seedling frame is transferred through the curved passage. Of the rotating brushes provided inside and outside the curved passage so as to be in contact with both sides of the seedling frame so as to be able to brush them, a plurality of support arms having a common rotation axis are provided so that the brushes on the inside of the curved passage can be brushed at multiple locations on the seedling frame. Each of the seedling frames is rotatably supported by a shaft, and is provided with water washing means such as a water sprinkling pipe for washing the seedling frames being transferred.

This makes the entire device compact by taking advantage of the flexibility of the seedling frame, and allows the seedling box to be inserted and ejected from one side, making cleaning work more efficient and effectively cleaning every corner of the seedling frame. The purpose is to clean.

The present invention will be explained in detail below based on nine illustrated embodiments.

(Configuration of the Embodiment) 1 is a housing whose rear part (the left part in the drawing) is curved in a semicircular shape, and is supported by nine machines 2. An insertion port 3 is provided at the upper front of the housing 1, and an ejection port 4 is provided at the bottom thereof.

A curved passage 5 is formed in a U-shape outside the housing 1 and communicates from the insertion port 3 to the discharge port 4. This curved passage 5 is
These are a group of 6 kite boards fixed to appropriate locations on the inner wall of the housing 1, and a surface frame transfer means installed inside the housing. It is formed by a guide roller 7an and a group of feed rollers 7b installed opposite to the group of guide rollers 7a. The distance between the aid roller rough a and the feed roller 7b is made equal to the height of the seedling frame. A pulley 8 is attached to one end of each feed roller shaft protruding outside the housing 1.

Reference numeral 9 denotes a pair of left and right support arms projecting in a cross shape from a base fixed to a shaft 10, each of which has a roller-shaped freely rotating brush 11 rotatably supported at its tip end, and supports the curved passage 5. is installed inside. Both ends of the support 10 protrude outside the housing 1, and boot 912.13 is attached to both ends of the support.

14 is a roller-shaped forced rotating brush fixed to a shaft 15 and is installed below the curved passage 5.

Both ends of the shaft 15 protrude outside the housing 1;

Boo IJ 16.17 chi is installed.

Reference numeral 18 denotes a motor, which is fixed on the machine stand 2 outside the housing 1, and which is connected to one of the forced rotation brush shafts 15 by IJ1.
A belt 19 is stretched between the motor 6 and the motor 18. Further, a belt 2o is stretched between the other boot 117 and one boot 3 attached to the support arm shaft 1o. Furthermore, a belt 21 is disposed at the center of the curved portion of the curved passage 5 on the other boot 2 and on the pulley 8 attached to the shaft of the feed roller 7b disposed close to the insertion port 3 and the discharge port 4. Belts 22 are stretched around the pulleys 8 of the feed a and rough b axes provided.

A sprinkler pipe 23 is fixed to the upper inner wall of the housing 1, and a hose 24 is connected thereto. Further, a drain 25 is provided at the bottom of the housing. 26 is a window cover for cleaning.

Note that the free rotating brush 11 and the forced rotating brush 14 are as follows:
Of course, the length of the bristles of the brush, the arrangement position, etc. must be considered so that the flexible seedling frame passing through the curved passage 5 can be brushed.

Instead of the above embodiment, the number of support arms (therefore, the number of freely rotating brushes 11) is further increased within a range that does not impair stability, and the freely rotating planar is located at a position that does not interfere with the guide roller 7a and feed roller 7b.

It is also possible to configure the seedling frame so that it abuts at three locations.

Furthermore, a plurality of 9 forced rotation blanks 14 are provided. Alternatively, the forced rotating brush may be rotatably supported to form a freely rotating brush.

(Function) From the above-mentioned configuration, while sprinkling water from the water pipe 24,
When the motor 15 is driven, the forcibly rotating brush 14 is rotated in the direction of the arrow in FIG. 1 by one belt.

Therefore, the rotation of the forced rotation brush J4 is transmitted to the support arm 1o of the free rotation brush 11 by the belt 2°, and the rotation of the support arm axis is transmitted to the feed roller 7b by the bell 1-21.22, and the rotation of the support arm 9. Feed roller 7b
also rotates in the direction of the arrow.

Therefore, the flexible seedling frame A inserted from the insertion port 3 with the - side down is moved through the curved passage 5 by the feed roller 7b while being showered by the watering pipe 24, and is reversed after passing through the curved part. It is discharged from the discharge port 4. While the seedling frame A passes through this curved passage, a free rotation plan 11 rotatably supported by a support arm 9 rotates nine times, and first brushes the - side of the seedling box in the curved passage on the side of the insertion opening. Then, it turned around in the curved passage on the discharge port side.
At the same time, the lower surface is brushed by forced rotating brushes installed oppositely across the curved passage.

Therefore, the seedling frame A is thoroughly cleaned by showering and brushing, and is then discharged from the discharge port.

(effect) The effects of this invention are listed below.

1 (1) Run the curved passage that inverts the flexible front frame.
By providing it within the group, the entire device can be made compact. Further, since the insertion port and the discharge port are provided on the same side, the two-way workability is extremely good.

(2) Since the negative side of the seedling frame is brushed at multiple locations, the cleaning effect is greater than with conventional cleaning machines.

(3) The freely rotating brush is supported by a plurality of support arms having a common rotation axis, and the transfer means and the brush can be driven by one drive source, so the configuration can be simplified.

(4) As a result of adopting a freely rotating brush, the flexible seedling frame will not be damaged.
