1MSF-2型立秆式地膜回收机的设计及试验研究

为解决秋收后棉田的地膜回收率低、适应性差、人工卸膜效率低及强度大等技术问题,研制了一种具有自动对行、起膜边、动态仿形搂膜及自动卸膜等功能的立秆式地膜回收机。田间试验结果表明:该机搂膜齿入土角度在20°~30°、搂膜齿安装间距为70mm、作业平均作业速度为7.4km/h的情况下,地膜回收率为90.2%,生产效率可达到5hm~2/h,各指标均达到设计要求。

Design and Field Experiment Research on the 1 MSF-2 Plastic Flim Recycling Machine

To solve the technical problem of low plastic film recycling rate , poor adaptability , low efficiency and big in-tensity artificial unloading residual plastic film on residual plastic film in cotton field after the autumn harvest , a plastic film recycling machine with the functions of separate individual imitation entering the cotton lines , stirring up the side of plastic film , automatic dynamic raking and unloading the plastic film has been developed .Field experiment results show that the angles of raking plastic film tooth into field within the scope of 20 °to 30 °;the installation distance of raking plas-tic film tooth is 70mm;and the average operating speed is 7.4 km/h.When the machine with the three configurations , the plastic film recycling rate was 90.2%,the production efficiency could reach 5 hm2/h.Each indicator could achieve the design requirements .
