Problems solved by technology

[0002] Due to the defects in the structural design of the existing air-suction seed metering device, the seeding point of the air-suction seed metering device is relatively high when it is equipped with a sowing machine. After being discharged by the type seed metering device, it must be transported by a long-sized seed delivery pipe before it can be put into the soil of the seed bed. Not only the structure is complex, but also due to the irregular and inconsistent The quality of sowing operation has not been improved due to the control of collision

Abstract

The invention relates to an air-suction type seeding device achieving vertical seed throwing at low position, and belongs to agricultural machinery. A drive shaft is installed on a fixing sleeve in a matched mode, a driving disc is fixedly installed on the drive shaft, an eccentric disc and an eccentric air-suction disc are fixedly installed on the fixing sleeve, a sealing round cover plate is installed on the eccentric disc, a crank shaft type seed suction and discharge pipe is installed between the sealing round cover plate and the driving disc in a matched mode, an arc-shaped airflow blocking boss is arranged on the lower side part of the inner wall face of the eccentric air-suction disc, a seed box is installed on the portion, below the sides of the eccentric air-suction disc, the sealing round over plate and the driving disc, of the eccentric air-suction disc in a matched mode, and a seed cleaning brush is arranged at a seed suction port of the seed box. Accordingly, low-position vertical seed throwing work of the air-suction type seeding device is achieved, seeds discharged by the air-suction type seeding device can be seeded on soil of seedbeds directly, a seed conveying pipe is omitted, and the air-suction type seeding device has the advantages of being novel, simple and reasonable in structure, good in quality of seeding work, high in precision and reliable in use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an air-suction seed metering device. Background technique [0002] Due to the defects in the structural design of the existing air-suction seed metering device, the seeding point of the air-suction seed metering device is relatively high when it is equipped on the sowing equipment. After being discharged by the type seed metering device, it must be transported by a long-sized seed delivery pipe before it can be put into the soil of the seed bed. To control the collision, the quality of sowing operation has not been improved. Therefore, it is very necessary to design a kind of air-suction type low-position vertical seed metering device to meet and adapt to precision seeding operations. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and combine the actual needs of production operations to d...
