滚筒式残膜回收机结构设计与研究

Structural Design and Research of Drum Residual Membrane Recovery Machine

为解决残膜回收问题,本文设计了一款体积小的滚筒式残膜回收机。该机具采用偏心弹齿挑膜的工作原理,通过起膜齿起膜、弹齿拾膜、脱膜装置脱膜、集膜箱收膜四个过程实现对残膜的回收。本设计在机架上加装耕深调节装置,可调整起膜齿角度与滚筒的离地距离,进而提高机具的适应性能。通过对弹齿运动轨迹与受力进行详细分析,确定了弹齿周向组数,实现了有效挑膜的连续性。该回收机适用于浅耕层、地膜厚度大于0.01mm和田间覆膜宽度600~900mm的残膜回收。该设计可在一定程度上提高残膜回收效率。

In order to solve the problem of residual film recovery,a small drum type residual film recovery machine was designed in this paper.The machine adopted the working principle of eccentric elastic tooth pick-up film,and re.alized the recovery of residual film through four processes:pick-up film,pick-up film,de-film device and film col.lecting box.A tillage depth adjusting device was installed on the frame,which could adjust the angle of the film-lift.ing teeth and the distance from the drum to the ground,thereby improving the adaptability of the machine.Through the detailed analysis of the trajectory and force of the elastic teeth,the circumferential group of the elastic teeth was determined,and the continuity of the effective film picking was realized.The machine is suitable for the recovery of residual film in shallow tillage layer,with film thickness greater than 0.01mm and film width of 600~900mm in the field.The design can improve the recovery efficiency of residual film to a certain extent.
