【摘要】：为解决方草捆捡拾效率低、费用高,长途运输难等问题,设计了方草捆集捆机。该机由底盘、捡拾器、推草机构、举草机构、压绳器和卸草机构等部件组成,基于EPEC2024搭建了控制系统,只需单人驾驶和操作,通过变量泵、马达和油缸驱动各部件快速实现对方草捆的捡拾、挤压和捆扎。按照作业功能对各结构部件采用分模块设计,通过计算各液压回路的流量保证作业速度和作业效率,匹配硬件电路并使用Codesys编写程序控制作业流程。分别在内蒙古自治区赤峰市和辽宁省黑山县对方草捆和秸秆方捆进行了捡拾及捆扎的场地试验,结果表明:整机最大牵引车速达到20.5 km/h,作业时系统最大流量为101.6 L/min,一次能实现12个方草捆的捆扎。方草捆的集捆成捆率达到89.5%,纯工作小时内集捆生产率为12大捆/h,同等条件下与人工捡拾方式相比,捡拾效率提高了34.5%,人工费用降低了62.5%,综合费用降低了18.2%,而且增强了对自然环境的适应性,缩短了长途运输的准备周期,满足实际生产的使用要求。
[Abstract]:In order to solve the problem of low efficiency, high cost and difficult long-distance transportation, a square baling machine is designed. The machine is composed of chassis, pickup device, weeds mechanism, grass lifting mechanism, rope press and grass unloading mechanism. The control system is built based on EPEC2024. Only single driver and operation are needed, and the components are driven by variable pump, motor and cylinder. Quickly realize the pick up, extrusion and binding of the bales of the other side. According to the operation function, the modules are designed by the modules, and the operation speed and efficiency are ensured by calculating the flow of each hydraulic circuit. The hardware circuit is matched and the Codesys program is used to control the operation process. In Chifeng, the Inner Mongolia Autonomous Region and the black mountain of Liaoning Province, The field test of collecting and binding the bales and bales of the straw bales and straw bales in the county showed that the maximum haulage speed of the whole machine reached 20.5 km/h, the maximum flow rate of the system was 101.6 L/min, and 12 square bales were tied at one time. The binding rate of the bales for square grass bundles was 89.5%, and the binding productivity of the pure working hours was 12 bundles of /h and the same bar. Compared with the artificial pickup method, the efficiency of picking up was raised by 34.5%, the labor cost was reduced by 62.5%, the comprehensive cost was reduced by 18.2%, and the adaptability to the natural environment was enhanced, the preparation period of long-distance transportation was shortened, and the requirements of the actual production were met.
