Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush driving device of a seedling raising pot cleaning device for cleaning the inside of the recess of the seedling raising pot while transporting the seedling raising pot.

[0002]

2. Description of the Related Art Conventionally, as a method for cleaning a continuously-grown seedling-growing pot, a known cleaning method has been known in which a nozzle is directed toward the pot surface to inject pressurized water or to brush the entire seedling-growing pot. ing.

[0003]

[Problems to be Solved by the Invention] Although many deposits such as culture soil adhere to the recesses formed in the nursery pot,
In order to clean each recess cleanly, the method of spraying water pressure on the whole seedling pot or brushing the whole surface is not sufficient, and a method of cleaning by inserting a brush in each recess Is desirable. However, the problem with this brushing method is the timing of brush insertion. First of all, if you insert the brush only up and down for the nursery pot that is transported horizontally,
The nursery pot may be damaged. However, it is inconvenient in terms of continuous cleaning to stop the transportation of the seedling raising pots one by one for brush cleaning. Therefore, there is a demand for a brush drive device capable of inserting, cleaning, and removing the brush without stopping the transportation of the seedling raising pot.

Further, the size of the recess of the seedling raising pot varies depending on the type of pot. Therefore, if the distance between the brushes is made constant, the position of the recessed portion will be displaced if the kind of seedling-growing pot is different, and this will hinder the cleaning work machine. Therefore, there is a demand for a brush driving device that can adjust the distance between the brushes according to the change in the distance between the recesses.

[0005]

The present invention uses the following method in order to solve the above problems. That is, the seedling raising pot having a cross-shaped recess is turned upside down and conveyed in the horizontal direction, and a cleaning brush is attached below the conveying path of the seedling raising pot so as to be aligned with the recessed position in a lateral row of the seedling raising pot. A body is provided, the support is arranged in a chain formed in a triangular shape in a side view, and the support is erected vertically when the support passes through the top apex of the chain. It is inserted into the recess of the chain and washed by rotating, and the angle of the apex of the chain is adjustable so that it can be matched with the pitch of the recess in the transport direction.

[0006]

The brush support is conveyed by a chain which is driven at the same speed as the conveying speed of the seedling raising pot, and the brush is inserted into the concave portion of the seedling raising pot being conveyed at the top of the chain. In the insertion position, the brush is directed vertically upward, and the brush bottom is pressed against the pusher during insertion to rotate the brush, wash the inside of the recess, and convey the brush to remove it from the inside. It In addition, when the shape of the seedling pot changes and the space between the recesses changes, the front-rear space of the brush support can be made equal to the space of the recess by changing the angle of the apex of the drive chain of the brush support. You can do it.

Axis of rotation 1
The drive chain 9 is wound around the drive sprocket 11 attached to the outside of the drive shaft 2, and the drive chain 9 is driven. Therefore,
Since the drive speed of the carry-out roller 6 and the drive speed of the brush drive device C are both obtained from the motor M2,
The brushes 19 can be matched with each other, and the transfer speed of the brush 19 supported by the brush support 18 described later is matched with the transfer speed of the seedling-growing pot P, and the brush 19 is inserted and cleaned while the seedling-raising pot P is transferred. It becomes possible.

In the structure of the brush driving device C, the structures of the brush transport chain 10 and the guide rail 17 will be described first with reference to FIGS. 3 to 8. As shown in FIG. 5, a drive sprocket 11 is fixed to the outer end of the rotary shaft 12 and a sprocket 14 is fixed to the inner end of the rotary shaft 12, and the rotary shaft 12 is rotatable around a cylindrical body 13 penetrating the side plate 4. Has been inserted into. The drive chain 9 is wound around the drive sprocket 11 as described above. Then, the brush transport chain 10 is wound in a triangular shape with the sprocket 14 as the apex and the movable sprockets 15 and 15 as the bottom end, and tension is applied at the bottom of the brush transport chain 10 (between the movable sprockets 15 and 15). The sprocket 16 is arranged. The movable sprocket 15 and the tension sprocket 16 are
As shown in FIGS. 7 and 8, the rotary shafts 15a and 16a are pivotally attached to the rotary shafts 15a and 16a, respectively.

As described above, the brush drive device C can insert the brush into each recess while rotating the container, rotate and wash the seedling, and remove the seedling while the seedling raising pot is being transported. It is possible to reliably insert each brush into each recess by adjusting the front-rear spacing of the brush support 18 in response to a change in the interval between the recesses that varies depending on the type of pot.

[0016]

The present invention has the following effects by being configured as in the claims. That is, the seedling raising pot is turned upside down and conveyed at a position above the brush cleaning device, during which the brush fixed in a vertically upper position is inserted into each recess, and the brush rotates at the insertion position. The inside of the recess is cleaned and then removed.
Since the pots are washed without stopping the transportation of the seedling raising pots, the work efficiency is good. Also, even if the shape of the recesses changes due to different types of nursery pots and the intervals between the recesses change, the front and rear spacing of the brush support that supports the brush is adjusted, and the angle of the sprocket at the apex position of the brush transport chain is adjusted. By doing so, an appropriate interval can be adjusted, so that a brush can be surely inserted into each recess for cleaning regardless of the type and shape of the seedling-growing pot.
