Secondary seed-feeding mechanism of drum-type hole sowing device

Abstract

The invention discloses a secondary seed-feeding mechanism of a drum-type hole sowing device, and belongs to the field of agricultural machinery. The problems that existing seed-feeding mechanisms cannot accurately fall in corresponding duckbill members to cause inconsistent seeds per bunch and unequal plant spacing can be solved. The seed-feeding mechanism includes a cylindrical seed-feeding mainbody; inner seed channels and outer seed channels are arranged in the seed-feeding main body; the inner seed channels communicate with the outer seed channels; outlets are arranged in the positions,on the outer side surface of the seed-feeding main body, of the inner seed channels; seed-blocking plates used for guiding seeds to enter the inner seed channels are arranged in the positions, on theinner side surface of the seed-feeding main body, of the outer seed channels; and tangential speed can be reduced after the seeds enter the inner seed channels from the outer seed channels.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a secondary seeding mechanism of a drum-type hole seeder. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The seeding process of the air-suction drum-type hole seeder is that the fan generates a pressure difference on both sides of the seed tray to adsorb the seeds on the seed tray. When the seeds rotate to the seeding position with the seed tray, the pressure difference disappears, and the seeds rely on their own weight. Enter the duckbill to complete the seeding. The inventor found that during the falling process of the seeds, due to the long distance between the seeding position and the duckbill, and the rotation of the hole sowing device, the seeds could not accurately fall into the corresponding duckbills, resulting in inconsisten...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a secondary seeding mechanism for a drum-type hole seeder, which can solve the problem that the existing seeding mechanism cannot accurately fall into the corresponding duckbill, resulting in inconsistent numbers of seeds in the holes and poor plant spacing. unequal problem
