气吹悬浮供种滚筒式播种机吸附取种理论分析
Theoretical Analysis of Cylinder Seed-metering Device and Adsorption Species Based on the Pneumatic Suspension Seed Supply
摘要
Abstract
According to the tomato plug seedling row for seeding process of seeds of the "single grain of single point" of the agricultural technology in Xinjiang, innovation designs a machine based on gas blowing suspension and suppling way of drum type tomato seeding , precision seeding in the process of multi-particle, hole, leakage sowing problem is solved. Through the introduction of the main structure of the seeder and seeding principle, analyze row for adsorption from process and seed instantaneous adsorption force and draw roller adsorption from the conditions. The primary and seconda-ry relationship of the main indicators of the performance of the plant is the main index of the air chamber pressure, the diameter of the suction hole and the rotating speed of the drum. When the gas chamber of the box structure is 2. 0kPa, the suction hole diameter is 1. 5mm, when the drum speed is 12r/min, the effect of the combined effect is more ideal. And through the experimental design and data processing, it is concluded that the optimal level combination, the statisti-cal results: rate of single seed:92 . 5%, multi-grain rate: 5 . 3%, the rate of hole:3 . 0%, air blowing suspended for roller type seedling row the seeding effect better, meet the agricultural requirements.关键词
