Airflow-assisted precise seeder

Abstract

The invention discloses an airflow-assisted precise seeder. The airflow-assisted precise seeder comprises a precise seed metering device and a tail end tilling and seeding device which are connected through a seed metering pipe. The precise seed metering device comprises a case, and a differential pressure type precise device is mounted in the case. The case is provided with a seed cabin and an air cabin, and an air inlet pipe for introducing airflow into the air cabin is mounted on the case. The differential pressure type precise device is arranged in the air cabin. On one hand, airflow injected by the air inlet pipe enables the differential pressure type precise device to operate so that seeds in the seed cabin are discharged into a seed discharging pipe, and on the other hand, the airflow enters the seed discharging pipe so as to assist seed discharging. The tail end tilling and seeding device comprises a seed feeding pipe and a seed pressing wheel, and the seed pressing wheel is used for pressing seeds fed by the seed feeding pipe. According to the airflow-assisted precise seeder, through airflow assistance, collision between seeds and the pipe wall of the seed feeding pipe is reduced, the fed seeds are pressed through the seed pressing wheel so that the seeds cannot bounce after falling to the ground, and the seeding quality is guaranteed while the seeding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an airflow-assisted precision seeder. Background technique [0002] High-speed and high-efficiency are the development trend of precision seeding technology, and the operation under high-speed conditions puts forward higher requirements for the performance of the seeder. With the increase of operating speed, the vibration of the planter is intensified due to the uneven ground surface, and the seeds discharged from the seed meter are easily collided with the pipe wall during the process of being transported through the seed pipe, which changes the original particle distance and causes the operation The consistency of the distance between plants becomes worse, so high-efficiency operation and operation quality are often not compatible. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present i...
