Embodiment

[0033] As a typical implementation of the present invention, please refer to Figure 1a ~ Figure 2 , this embodiment discloses a secondary seeding mechanism for a drum-type hole seeder, which includes a cylindrical seeding body, the seeding body specifically includes a cylindrical outer wall 1, and the inner side of the outer wall 1 is connected to As for the side panels, it can be understood that the side panels are ring-shaped, and the inner side of the outer side wall 1 is connected to three side panels including the first side panel 6 , the second side panel 7 and the third side panel 8 .

[0034] In this embodiment, considering the trajectory requirements of the seeds 12, the first side plate 6, the second side plate 7 and the third side plate 8 are not arranged in parallel, and the first side plate 6 and the second side plate 7 are arranged from the inner edge to the The direction of the outer edge gradually moves away. It can be understood that the second side plate 7 ...

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...
