Description

[Detailed Description of the Invention] The present invention relates to a rotary brush mechanism for leveling soil that can be incorporated into a seedling-raising seeding device.

Normally, the bed machine and soil covering machine of this type of seeding device have a simple structure that uses a belt conveyor to take out soil in fixed quantities from a hopper and supply it to the seedling box, and both types can be used for both with the same structure. In addition, the seedling box transfer mechanism can reciprocate the seedling box by simply reversing the drive direction, and by simply placing the Dojin Machine □ and the seeding machine on the transfer mechanism, you can perform on-bed feeding, sowing, and soil covering. It becomes possible to carry out a series of supply operations.

However, a brush mechanism must be placed behind the bed machine to level the upper surface of the bed, and if this brush mechanism is placed, the seeds sown in the seedling box before the soil covering work will be blown away, which is a problem compared to conventional methods. In the above, the transfer mechanism is not reversed and one Dojin machine is used for both above-the-floor supply and covering soil supply.

Furthermore, in the past, the height of the upper surface of the bed was constant, and it was difficult to finely adjust it depending on the type of soil or seeds.

In view of the problems of the conventional device, the present invention makes it possible to retract the rotating brush upward from the seedling box.
Soil that allows the height of the top surface above the bed to be adjusted by moving the seedling box back and forth so that one Dojin machine can be used for both above-the-floor supply and covering soil supply, and by making it possible to finely adjust the height of the rotating brush. The purpose is to provide a rotating brush mechanism for break-in.

The feature of the present invention to achieve this purpose is that the seedling box is placed between the Dojin machine and the seeding machine, which are arranged in series along the forward/reverse switchable seedling box transfer mechanism that reciprocates the seedling box. A rotary brush mechanism for leveling soil, comprising a frame body rotatable with respect to a frame of a transfer mechanism, and a rotary brush rotatably supported by the frame body and capable of sliding contact with the floor in a seedling nursery box. The frame is provided with a height adjustment member that finely adjusts the height of the rotating brush relative to the seedling growing box to adjust the height above the floor, and the height adjustment member can be inserted and retracted between the frames. There is provided a retracting member which is interposed to retract the rotating brush above the seeds in the seedling raising box.

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