Description

The present invention relates to a seedling feeder for a seedling plant.

[Conventional technology]

Conventionally, there has been provided a seedling feeding device which operates so as to perform a seedling feeding action in a seedling transfer direction, on a lower side of a seedling mounting table provided to be inclined so as to be lower in the seedling transfer direction.

[Problems to be solved by the invention]

In the above-mentioned conventional one, the seedlings subjected to the seedling sending action by the seedling sending device are transferred accurately. However, if the next seedling following the seedling feeder is not directly affected by the seedling feeder, the subsequent seedlings will only slide down the slope of the seedling platform. It moves in the seedling transfer direction.

At this time, if the subsequent seedling has a poor slip on the seedling mounting table, a gap occurs with the preceding seedling, and therefore, there is a problem that the seedling is not continuously supplied and the seedling is lost. .

Conversely, if the subsequent seedlings slide too well on the seedling mounting table, when the seedlings are not fed, the following seedlings will be too close to the preceding seedlings due to the vibration of the aircraft, etc., and the seedlings will move in the transfer direction. There is a problem that the seedlings are compressed and thus the number of seedlings planted becomes larger than the set number.

In addition, it is conceivable to extend the seedling feeding operation surface for the seedling of the seedling feeding device to the subsequent seedling or to separately provide a seedling feeding device for the subsequent seedling, but in this case, the subsequent seedling is moved forward. Problems that it is difficult to place the seedlings on the seedling mounting table in a state following the seedlings without gaps and that the weight and cost become too large are expected.

Therefore, the present invention has a relatively simple configuration without increasing or providing a plurality of seedling feeding devices, and succeeding seedlings that are not subjected to the seedling feeding action of the seedling feeding device move satisfactorily in the seedling transfer direction. The task is to do so.

[Means for solving the problem]

In order to solve the above problem, the present invention is provided with a seedling feeding device 25 that operates to act as a seedling feeding action in the seedling transfer direction on the lower side of the seedling mounting table 12 that is provided to be inclined so as to be lower in the seedling transfer direction, A rolling member 35 that rolls in the seedling transfer direction and supports the seedling is provided on the upper side of the seedling mounting table 12, and the rolling of the rolling member 35 is braked when the seedling feeding device 25 does not operate the seedling feeding. This is a seedling feeder for a seedling plant, which is provided with a braking means 38.

[Action]

In the seedling feeder of this seedling transplanter, the preceding seedling located on the lower side of the seedling mounting table 12 receives the seedling feeding action in the seedling transfer direction by the seedling feeding device 25 provided on the lower side of the seedling mounting table 12. Transported properly.

Further, the following seedlings located on the upper side of the seedling mounting table 12 are supported by the rolling members 35 provided on the upper side of the seedling mounting table 12 so as to be able to roll in the seedling transfer direction, so that the seedlings are fed. Sometimes, the sliding member 35 slides down smoothly and the rolling of the rolling member 35 is braked by the braking means 38 when the seedling feeding is not performed.

〔The invention's effect〕

Therefore, according to the present invention, the following seedlings that are not subjected to the seedling feeding action of the seedling feeding device 25 can be favorably moved in the seedling transfer direction with a relatively simple configuration without increasing the size or providing a plurality of seedling feeding devices. The seedlings can be moved, and a plurality of seedlings can be continuously and satisfactorily transferred.
