摘　　要：【目的】研究农田滴灌带人工回收劳动强度大、卸载困难、易断带等,设计一种仿人工挑带动作的挑带式滴灌带回收机。【方法】回收机主要由卷带机构、导向机构、挑带机构以及机架等组成。卷带机构由多连杆机构组成,通过移动滑块可实现滴灌带的快速卸载;建立并求解导向机构和挑带机构数学模型;利用动力学仿真软件ADAMS建立滴灌带回收机的虚拟样机模型。【结果】获得导向机构参数:曲柄长155 mm,连杆长439mm,偏心距长248 mm时,传动效果最佳;获得挑带机构参数:曲柄长141 mm,挑杆长366 mm时,满足挑带高度500 mm的要求;仿真分析发现:随着导向机构和挑带机构转速的增加,滴灌带内张力逐渐增加,最终确定导向机构的转速为0. 8 r/s,挑带机构转速0. 6 r/s。【结论】仿人工挑带式滴灌带回收机1 h作业面积约1hm2,可以快速完成滴灌带的卷带、卸载。【Objective】In order to solve the problems such as the heavy intensity of labor,low recovery efficiency and drip irrigation belt fracture,this paper designs a drip irrigation belt recycling machine which can imitate the action of manual pulling belt.【Method】The reclaiming machine is mainly composed of the reeling belt mechanism,guiding mechanism,picking belt mechanism,frame and other components.The reeling mechanism consists of a multi-linkage mechanism,and the drip irrigation belt could be quickly uninstalled by moving the slider.Then the model for its key mechanism such as winding belt mechanism and picking belt mechanism,moreover the virtual prototype of the belt and drip irrigation was created under the recovery unit based on dynamic simulation software ADAMS.【Result】The parameters of the guide mechanism were obtained as follows:crank length 155 mm,connecting rod length 439 mm,eccentricity 248 mm,which can attain the best transmission effect;parameters of the picking belt mechanism were obtained as follows:crank length 144 mm,rocker length 366 mm,meeting the requirements of picking height 500 mm;simulation analysis found that:with the increase of the speed of the guiding mechanism and picking belt mechanism,the tension in the drip irrigation belt gradually increased.Finally,the rotational speed of the guiding mechanism was set to 0.8 r/s,and the speed of the picking belt mechanism was 0.6 r/s.【Conclusion】The recovery machine has an working area of about one hectare per hour,which can quickly complete winding and unistalling the drip irrigation belt,thus greatly reducing the tape breakage rate.
