Rotatable air-suction vibration type sowing device

Abstract

The invention discloses a rotatable air-suction vibration type sowing device which is mainly used for precisely sowing seeds and comprises a rack, vibration seed plate devices, seed suction devices, seed feeding devices, a controller and an air pressure source device. A cylinder is used for pushing a thimble to move to clear away blockages in a seed suction nozzle of the sowing device; by the adoption of an adjustable levelness bracket for adjustment, levelness of the surfaces of vibration seed plates of the sowing device can be adjusted; the mobile seed feeding devices are used for quantitatively and uniformly feeding seeds; by the adoption of an air-suction vibration principle, automatic and precise sowing is realized. According to the rotatable air-suction vibration type sowing device, nozzle blocking of the seeds can be prevented, and uniform seed feeding can be realized; meanwhile, precise seed suction and discharging are realized; the rotatable air-suction vibration type sowing device is expected to be popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of sowing, and in particular relates to a rotary air suction vibrating sowing device. Background technique [0002] my country is a large agricultural country. With the advancement of science and technology, agricultural mechanization has become a trend. High-efficiency and precision seeding plays a very important role in promoting agricultural production. [0003] The existing air-suction seeder cannot realize multiple functions in one. For the air-suction planter, the seeds are easy to block the suction nozzle, resulting in the inability to suck the seeds in the next step. During the vibration of the vibrating seed plate, how to Adjust the levelness of the vibrating seed disk surface. When the seeds in the seed box are at a certain amount, the seeds should be added evenly in time. How to add seeds precisely and quantitatively? A rotary air-suction vibrating seeding device can prevent seeds from blocking t...
