A high-speed precision seed metering device combining seed pushing and air blowing

Abstract

The invention belongs to the technical field of agricultural machinery and relates to a high-speed precision seed metering device combined with seed pushing and air blowing. The seed metering device is mainly composed of a seed box, a seed metering unit and a frame, and the seed box is fixed on both sides of the frame for support On the board, the seed metering unit is installed on the front and rear beams of the frame. The seed metering unit consists of a seed plate, an outer plate, an outer plate fixing frame, a seed pushing device, a spring mounting frame, an outer ring air injection device, a motor-driven wheel device, and a seed guiding device. It consists of a device and a spring. The amount of seed is determined once by designing the size of the seed filling area. By controlling the speed of the runner and the stretching of the spring, the speed and movement of the seed pushing device are adjusted. The nozzle plugging rod cooperates with the nozzle of the outer ring air injection device to realize the synchronous work of pushing seeds and blowing seeds, filling seeds and closing air. The invention has a simple structure and a reasonable design, and can effectively solve the problems of high work consumption and slow seeding speed of the existing seed metering device, thereby realizing precision seeding and high-speed seeding operations.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a high-speed precision seed metering device combined with seed pushing and air blowing. Background technique [0002] Precision sowing is a method of sowing the seeds of crops into the seedbed according to the precise sowing amount, row spacing and sowing depth. Precision seeding has the following outstanding advantages, such as: saving seeds, even planting, reasonable plant spacing, increasing yield, etc. The key is a seed metering device that can achieve high-speed and stable seeding, and its performance will be directly related to the quality and efficiency of sowing . The air-blown precision seeder can achieve more precise sowing of large-grained seeds, and the seed damage rate is lower. The main working principle of the traditional air-blown precision seed metering device is that the seeds complete the seeding operation under the action of gravity and air pr...
