[0031]

The multi-hole seeding device of the present invention has the following advantages.

(1) Since the multi-film is successively stabbed into the ground while covering the ground and the holes are sown by the cups and the seeds are sown in the holes, the multi-sowing operation can be easily and efficiently performed.

(2) Since a plurality of stab cups connected by a rotating driven wheel are stabbed into a multi-film in order and a hole is made in the multi-film, the seeds in the stab cup are sown into the holes. By simply changing the rotation speed of the driven wheel with respect to the traveling speed of the machine, it is possible to change the distance between the stocks within a certain range to perform multi-hole seeding, which is convenient for work and increases versatility.

(3) Since it is not necessary to process the multi-film such as making holes, the multi-film can be easily manufactured at low cost.

(4) A large number of stab cups connected by rotating driven wheels are stabbed into a multi-film one after another, pierced in the multi-film and stabbed in the soil, and then the coraplet piece of the stab cup is opened. Since the seeds in the piercing cup are sown in the soil, there is always seeds in the holes of the multi-film, and the seeds do not shift from the holes in the multi-film. You can do it.

(5) Since the piercing cup rises with the cormorant piece open and escapes from the multi-film, the holes formed in the multi-film have the same size throughout, which is beneficial for the growth of crops.

(6) A driving wheel and a driven wheel, which are transmitted from the wheels of the seeder, are vertically eccentrically eccentrically supported, respectively, and a large number of vertical parallel links are provided between the outer periphery of the driving wheel and the driven wheel. A mounting shaft, which is disposed and pivotally supports one end of the link on the drive wheel and fixes the other end, is pivotally supported on the driven wheel. Fix the inverted cone-shaped piercing cup. Therefore,

(A) The driven wheel accompanies the drive wheel through a large number of parallel links in the vertical direction from the drive wheel and rotates smoothly and smoothly, and a large number of piercing cups attached to the large number of parallel links are suitable. Accurately move up and down, accompany the driven wheels and make a turning transition.

(B) Since the piercing cup always moves in the vertical direction, a seed box for supplying seeds into the piercing cup can be simply constructed to properly supply seeds into the piercing cup. In addition, the piercing cup can be pierced into the multi-film and the holes can be pierced smoothly and accurately.

(C) Since the piercing cup moves in the vertical direction and pierces the multi-film, the rotation speed of the driven wheel relative to the traveling speed of the machine is slightly changed depending on the type of seeds, etc. There is no fear of pulling the multifilm at times, or pulling the multifilm when the width is changed, so that the multifilm is less likely to be wrinkled, and the multifilm can be sown while always being well covered.

(7) The structure is simple, the manufacturing is easy and the manufacturing cost is low, and the operation is light and smooth.
