| 为了解决捡拾率低、捡拾机构缠膜率高、脱膜困难等残膜回收难题，设计了一种集条残膜捡拾打捆机的杆齿滚筒式残膜捡拾机构，可同时完成残膜捡拾与脱膜作业。捡拾机构采用双曲柄工作原理，建立了捡拾机构的余摆线运动方程，通过对相邻杆齿产生的挑膜盲区分析，确定了相邻伸缩杆齿安装角为45°、圆周排列为8组，设计了两组交错排列的连杆来确保机构运动的稳定性。样机田间试验表明机具作业速度为1.7 m·s-1、杆齿轴转速为60 r·min-1、杆齿入土深度为40 mm情况下，机具平均捡拾率为90.66%，平均清杂率为82.14% |

| In order to solve the difficult problems for collecting plastic film residue as low pickup rate and difficult to remove film, we designed a set of rod-tooth-roller'plastic film residue bundling machine that can simultaneously completed to pick up plastic film residue and stripping operation. The pickup mechanism adopted double crank working principle, set up the cycloid motion equation of the pickup mechanism.Through the analysis for the blind zone of pick up film caused by the adjacent rod tooth, determined that the installing angle of the adjacent telescopic rod was 45°, and the circumference arrangement was 8 groups, designed two sets of staggered connecting rods to ensure the stability of the mechanism movement. Carried out the field test for prototype machine, the test showed that：Under the conditions as the machine operation speed was 1.7 m·s-1, the rod-tooth shaft speed was 60 r·min-1, and the rod-tooth penetrated soil depth was 40 mm, the average pickup rate was 90.66% and the average impurity removing rate was 82.14%. |
