    Design and experiment of roll-shaft-type packing device for residual film

      摘要
    • 摘要:
      目的 针对国内现有残膜打包装置成捆机理不明确、作业时出现残膜逃逸、膜包杂质含量过高等问题，设计一种集残膜清杂及残膜打包为一体的辊轴式残膜打包装置。
      方法 该装置主要由清杂输送机构、打包机构、传动系统等组成。通过理论分析建立清杂输送辊与残膜的力学关系，确定清杂输送辊的结构参数；根据清杂输送机构结构特征与作业原理，分析并确定清杂输送辊的布置间隙。采用机理分析方法分析残膜捆芯形成过程中残膜的受力与运动情况，并确定打包辊的运动参数。以成捆率和膜包含杂率为指标，机具前进速度、清杂输送机构倾斜角度、打包辊转速为试验因素进行正交试验，并对较优的参数组合进行田间验证试验。
      结果 影响成捆率的主次因素依次为打包辊转速、清杂输送机构倾斜角度和机具前进速度；影响膜包含杂率的主次因素依次为清杂输送机构倾斜角度、机具前进速度和打包辊转速。以成捆率为主要指标，确定的较优作业参数组合为：清杂输送机构倾斜角度为10°、机具前进速度为1.5 m/s、打包辊转速为200 r/min。田间验证试验的膜包成捆率为98.1%、膜包含杂率为15.2%。
      结论 该残膜打包装置满足田间作业要求，作业效果好，可为辊轴式残膜打包装置的设计与研究提供参考。

       

      Abstract:
      Objective Aiming at the problems of unclear bale formation mechanism of the existing domestic residual packing device, escape of film residues and high impurity content of film bales during operation, we designed a roll-shaft-type residual film packing device which integrated film cleaning and film baling.
      Method The device was mainly composed of cleaning and conveying mechanism, baling mechanism, transmission system and so on. Through theoretical analysis, we established the mechanical relationship between the cleaning conveyor roller and the residual film, and determined the structural parameters of the cleaning conveyor roller. According to the structural characteristics and operation principle of the cleaning conveyor mechanism, we analyzed and determined the arrangement gap of the cleaning conveyor roller. The mechanism analysis method was used to analyze the force and movement of the residual film during the formation of the residual film core, and determine the movement parameters of the baling roller. The bale formation rate and bale impurity inclusion rate were used as indicators, and the forward speed of the machine, the tilting angle of the film removal conveyor and the baling roller speed were used as test factors for orthogonal tests, and the best combination of parameters was tested in the field.
      Result The main and secondary factors affecting the bale formation rate were the baling roller speed, the tilting angle of the cleaning conveyor and the forward speed of the machine, while the main and secondary factors affecting the bale impurity inclusion rate were the tilting angle of the cleaning conveyor, the forward speed of the machine and the baling roller speed. Using the bale formation rate as the main indicator, the optimum operating parameters were determined as follows: The tilt angle of the cleaning conveyor was 10°, the forward speed of the machine was 1.5 m/s, and the speed of the baling roller was 200 r/min. The bale formation rate in the field verification test was 98.1%, and the bale impurity inclusion rate was 15.2%.
      Conclusion This residual film packing device meets the requirements of field operation and has good operation effect, which can provide references for the design and research of roll-shaft-type residual film packing device.
