Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a transplanter that takes out seedlings such as onions one by one from a seedling tank and plants them in a groove.

(Prior technology) As a transplanter for planting onions etc.
Techniques such as Japanese Patent Publication No. 31 (Conventional Example 1) and Japanese Patent Publication No. 57-16602 (Conventional Example 2) have been proposed.

(Problems to be Solved by the Invention) In Conventional Example 1, seedlings are lined up vertically and fed to a disk-shaped implantation device by a crank-moving planter arm, which is difficult to ensure continuous transplantation. In this case, the tank containing the seedlings must be moved laterally each time one seedling is taken out, which not only complicates the mechanism but also makes it difficult to synchronize the horizontal movement of the tank with the crank motion of the planter arm. The damage to the seedlings was also severe.

In Conventional Example 2, a conveyor is provided in the seedling tank, and the conveyor supplies the seedlings to a disk-shaped planting device.During this feeding, it is not possible to expect the seedlings to clump one by one, and in the end, the clumps must be done manually. The work became indispensable, and there was a problem in terms of labor saving.

The present invention is capable of securing a clump that causes less damage to the seedlings by pulling out the seedlings in the longitudinal direction of the stems while keeping them in close contact with each other using suction force, and also provides a transplanting method in which the seedlings are sequentially supplied to a planting mechanism. The purpose is to provide a machine and save labor.

The seedling extractor 38 and the seedling receiver 45 of the mechanism 8 have a rotating single seedling extractor mechanism 12 having a suction section 70 that performs a suction action between the seedling extractor 38 and the seedling receiver 45 of the mechanism 8. A roll brush 75 is provided near the single seedling take-out mechanism 12 for feeding the seedling 30 while pinching it in the same direction as the take-out direction of the mechanism 2.

(Function) The suction part 70 of the single seedling take-out mechanism 12 removes the seedling tank 7.
When the seedlings 30 in the seedling tank 7 are suctioned closely together and the single seedling takeout mechanism 12 having the suction part 70 is rotated in the direction of arrow 11 shown in FIG. The seedling receiving section 45 of the mechanism 8 plants the seedlings while dividing them one by one in the direction.
When the suction action is released in the seedling receiving section 45, the mechanism 8 is able to plant the seedlings 3.
0 and by rotating the mechanism 8 in the direction of the arrow shown in FIG. Ru. Then, the seedlings 30 are fed in the same direction as the mechanism 12 with a roll brush 75 provided near the single seedling take-out mechanism 12 in the seedling take-out section 38 while holding the seedlings 30, and the brush 75 allows the seedlings 30 to be neatly removed. will be done.
