Pneumatic roller type tray seeder

Abstract

The invention discloses a pneumatic roller type tray seeder. The pneumatic roller type tray seeder comprises a rack, wherein the rack is provided with a tray seeding device with a seed containing hopper and a tray transferring device; the tray seeding device is arranged above the tray transferring device and comprises a seed containing roller, a left joint and a right joint; the left joint and the right joint are respectively and fixedly connected to the two ends of the seed containing hopper by a left blocking ring and a right blocking ring; the seed containing roller is provided with a seed distributing roller, a seed falling roller and a hole pressing roller in a sheathing manner from inside to outside in sequence. The pneumatic roller type tray seeder disclosed by the invention has the advantages that the structure is simple, the use is convenient, the seeding accuracy is high, the seeding and the hole pressing are integrated, and the mechanical continuous production of hole discs is realized; the seed containing roller and the seed falling roller are respectively provided with a seed-containing impurity removing hole and a seed-falling impurity removing hole, and impurity removal is carried out on seed distributing holes and seed discharging holes by utilizing a seed-blowing air chamber, so that good anti-blocking effect is achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a pneumatic roller type tray seeder. Background technique [0002] Tray seeders are generally divided into washboard-type tray seeders, socket-type tray seeders and air-suction roller-type seeders. Both the washboard type tray seeder and the socket type tray seeder have disadvantages such as low seeding accuracy, complex structure, easy blockage, and low seeding efficiency, while the air suction roller type seeder has high precision, but the cost is high. There are shortcomings such as easy blockage, unstable negative pressure, and missed seeding during work. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a pneumatic roller type tray seeder with simple structure, convenient use, stable operation and high sowing precision. [0004] To achieve the above object, the present invention can ta...
