摘　　要：采用高速摄像技术对改进型夹持式棉花穴播轮的工作过程进行了分析。分析得知,充种区的种子作大、小2个环流运动,可实现两次冲刷充种,种子相对种子室的运动较改进前有所增大,从而增大了充种机率;取种器漏充的主要原因是2粒种子横向并排摆放在夹种口中引起的;清种方式有3种:即种子在重力作用下落下、夹种口变小种子被挤出夹种口和种子的平衡位置被破坏落下;种子进入夹种口的平均速度随穴播轮转速的增大而逐渐减小。For the randomness and uncertainty of seed movement in sowing process of the clamping dibbler,high-speed photography technique was used to analyze the operating process of the improved clamping dibber.The seeds in seed-collecting area could make two seeds circulation movements flows,which could make twice scouring seed-filling,and the seed speed relative to the seed-room was greater than unimproved dibbler,so the probability of seed-filling was increased.The main reason leading to seed-missing of seed-collecting devices was that two seeds were placed in parallel in the seed-clamping mouth.There were three ways to achieve seed-cleaning operation,one was that seeds fall under the action of gravity,another was that seeds were squeezed out the seed-clamping mouth with the seed-clamping mouth litter,and the third was that seeds fall due to the equilibrium position of seeds disappear as the dibbler rotating.The average velocity of seeds entering the seed-clamping mouth decreased gradually with increasing of dibbler rotational speed.The findings were beneficial to comprehend the working process of dibbler microscopically.
