Description

  The present invention relates to a seeder that enables single seeding and specific number seeding with one grip without damaging the epidermis of the seed.

  Conventional methods for sowing small seeds of vegetables such as radishes and carrots are mainly carried out by transferring the seeds packed in the field or vegetable garden to the palm and spotting them on the soil while squeezing them with fingers. . However, it is not easy to sow expensive seeds, while skillful fingertips are required for spot sowing while appropriately sown with a finger at a seeding amount suitable for the seed growth state. It was.

  In addition, in order to sow an appropriate amount of seeds uniformly and continuously, a higher level of skill is required. For beginners, by seeding more than the necessary amount of seeds, Thinning work was required and the purchase cost of seeds was increased.

On the other hand, it is desirable that the following requirements are satisfied in a seeder that seeds one seed of vegetable or flower seeds on soil such as a field or a vegetable garden.
(A) The structure should allow seeding work for each grain in accordance with the operator's intention.
(B) The structure can be switched for each grain and each grain.
(C) A structure that can be sown according to the seed type and size.
(D) The structure should not damage the seed epidermis during seed selection and transportation.
(E) It must be easy to hold with a hand type and be able to sow in a posture that does not bend the waist.
(F) The seed sowing amount should be visible from the outside.
(G) Easy sowing operation and maintenance work.
(H) Small size, light weight and simple structure.
(I) Be inexpensive.

  Conventionally, a hand type seeder that satisfies the above requirements has been proposed. For example, a seed placed in a seed hopper is fitted into the center of the width of the middle plate through the hole in the upper plate of the main body frame in which the upper plate, the middle plate, and the lower plate are stacked and slides. A possible seed pusher bar always falls into a waiting hole at the initial position where it is pushed out by a spring, the size and quantity of small seeds are determined by the volume of the hole, and then pushed to the predetermined position of the pusher bar Thus, a “seeder” (see Patent Document 1) is proposed, which has a structure in which seeds fall downward from an outlet pipe below a hole in the central portion of the lower plate with a forward width.

  However, the proposal of the above “seeder” (see Patent Document 1) is based on the aforementioned (a), (b), (c), (d), (f), (g), (h), (i The seeds that were pushed in by the extrusion rods slid against the wall surface of the hole in the center and damaged the epidermis of the seeds.

  In addition, a partition plate having a rhombus opening that opens downward is provided at the tip end of a hollow shaft that is composed of an upper frame and a V-shaped lower frame, and a V-shape that is continuous with the lower frame is provided at the lower front of the partition plate. And a rotating body composed of an abacus ball-shaped elastic member inscribed in the inner surface of the delivery groove and the rhomboid opening of the partition plate, and a flow of a size that allows seeds to pass under the partition plate. A “seed sowing device” (see Patent Document 2) in which a delivery opening smaller than the seed is formed at the contact point between the outlet and the delivery groove has been proposed and is known.

  However, the proposal of the above “seeding device” (see Patent Document 2) does not satisfy the requirements (a), (b), (c), and (f) described above. Since the total length is short, sowing work cannot be done without bending the waist, and because the seeds are sandwiched between a rotating body and a V-shaped lower frame and sent out, the seeds are sent continuously and the worker The seeds could not be reliably transported in accordance with the intentions.

  In addition, there is a “seeder” (see Patent Document 3) composed of a container for storing seeds related to the present applicant, a main body for adjusting the sowing operation and the sowing amount, and a guiding portion for leading to the seed sowing position. It has been proposed and is a known technique.

  However, the proposal of the above “seeder” (see Patent Document 3) does not satisfy the above-mentioned requirements (b), (c), and (d), and in particular in the step of seeding each grain by a flat plate By adopting the separation method, it was a structure that would damage the epidermis of the seed.

  The present applicant solves the problems of the conventional seeder as described above, satisfies all the requirements of the above-mentioned seeder, and enables seeding of one seed without damaging the epidermis of the seed. For farm workers, a hand-type one-grip structure that reduces the degree of fatigue in farm work has been developed, and the seeder has a light and simple structure, and has developed an inexpensive single seeder. This leads to the proposal of a “single-seeding seeder”.
