High-speed pneumatic precision sprouting seed discharging device with oppositely arranged tilting discs

Abstract

The invention discloses a high-speed pneumatic precision sprouting seed discharging device with oppositely arranged tilting discs. The high-speed pneumatic precision sprouting seed discharging devicecomprises a box body, wherein air chambers are formed in the outer walls of inclined wall surfaces, and seed sucking discs corresponding to the air chambers are arranged on the inner walls of the inclined wall surfaces; seed cleaning sawteeth are arranged above the seed sucking discs, a universal joint transmission device is arranged in the box body and comprises a constant velocity universal joint and a transmission shaft arranged at the end of the constant velocity universal joint, the two ends of the constant velocity universal joint are arranged on the seed sucking discs, and the transmission shaft penetrates through the seed sucking discs and the box wall of the box body and extends out of the air chambers; a transmission chain wheel is arranged at the end of one transmission shaft outside the box body, and a seed blocking partition plate is arranged in the box body portion below each seed sucking disc; seed dropping holes are reserved between the inner walls of the other side wall surfaces of the box body and the seed blocking partition plates. The high-speed pneumatic precision sprouting seed discharging device is simple in structure, long in service life and capable of meeting seed discharging requirements in a high-speed working state, and has the advantages of being high in seed sucking performance, good in seed feeding and discharging stability, good in adaptability,high in operation efficiency, low in seed leakage rate and damage rate and low in energy consumption.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a high-speed pneumatic seed metering device for bud seeds with opposed swash plates. Background technique [0002] At present, a large number of rural labor forces are transferring to urban and rural areas, and there is a serious shortage of labor force. The decentralized management of rural land has changed to large-scale operation. High-speed and efficient operation and seeding is an important research direction in the future. The seed meter is the core component of the direct seeding machine, and its performance is directly related to the quality and efficiency of sowing, and plays an important role in the development of rice direct seeding technology. Compared with the mechanical type, the pneumatic type has the characteristics of good adaptability to the shape of the seeds, low damage rate, high operation quality, and good seeding uniformity. [0003] When the working ...

Problems solved by technology

[0003] When the working speed of the existing seed meter is increased, the seed filling effect is not good, resulting in serious missed seeding phenomenon. Increasing the pressure can improve the seed filling performance to a certain extent and reduce the "flying seed" phenomenon, but at the same time it will greatly increase the reseeding index, resulting in seed failure. waste and agronomic requirements that affect planting
