Description

Four-rod translation type seed sowing device special for cell breeding

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a four-rod translation type special seed sowing device with a function of quickly cleaning and changing seeds for cell breeding and sowing operation.

Background

The seeding area is usually small, the variety and the specification of the sowed seeds are various, and the biggest problem in the seeding operation process of the district breeding is to prevent the mixture of crops, namely, each district must be absolutely pure, and no exogenous seeds are mixed in a single district. Therefore, a strict technical requirement of anti-hybrid design is provided for the cell seed-breeding seeder, namely, after the seeding operation is completed in the previous cell, the seeds left at each part in the seed-metering device must be cleared so as to facilitate the seed-changing seeding operation in the next cell. At present, the community breeding seeder mainly comprises imported and domestic seeders, wherein the imported seeder is high in price and has the problems of water and soil inadequacy and incapability of adapting to the unique planting mode of China, and the domestic community breeding seeder adopts a plug-in type seeding device, is complex in machine structure and high in operation labor intensity and needs to be provided with a special seed cleaning mechanism. Therefore, the seed sowing device special for the community breeding and having the functions of simple operation and rapid seed cleaning has important practical significance.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and researches and designs a special four-rod translation type seed sowing device for cell breeding, which quickly loads seeds in seed boxes and seed sowing disc nests into a collecting box hoisted by a connecting rod in a mode of moving and rotating a seed sowing disc with a handle, then finishes returning and changing the seeds of the seed sowing disc and further finishes the sowing operation of the next cell.

The invention aims to realize that a collecting box lower part of a side lower part is provided with a seed guide pipe, the collecting box is hinged with a front connecting rod and a rear connecting rod which are equal in length by a side bolt group, the front connecting rod and the rear connecting rod are hinged with the upper side part of a shell by the side bolt group and form a parallelogram mechanism, the upper part of the shell of which the rear lower end is provided with a mounting hole forms a seed box by a side plate fixedly arranged by an upper bolt group, the lower part of the seed box is fixedly provided with a brush by a small bolt group on the shell, the middle part of the shell is rotatably assembled by a bearing, a driving shaft of a circular shaft section and a hexagonal shaft section is sequentially arranged from outside to inside, the bearing is fixed by an end cover fixedly arranged by a middle bolt group, the hexagonal shaft section is sleeved with a seed discharging disc with holes uniformly distributed in the circumferential direction by hexagonal holes, the seed discharging disc is fixedly provided with a handle with a large shaft hole in, the convex shaft is inserted into a U-shaped hole formed in the middle of the front connecting rod, so that the special seed sowing device for four-rod translation type cell breeding is formed.

After the seeding operation of the previous cell is completed, the seed in the seed box and the seed holes fall into the collecting box hinged to the shell by the front connecting rod and the rear connecting rod by self weight, then the seed discharging disc is returned inwards by holding the handle, at this time, the seeds in the next cell are poured into the seed box, and then the seeding operation of the next cell is completed.
