针对平面式草帘编织机人工摊铺秸秆上料用工量大等问题,该文通过模拟稻秸秆人工摊薄、铺放的作业过程,研制了一种与现有草帘编织机配套使用的自动摊铺分束装置。该装置采用多连杆对切机构和耙分机构,可对稻秸秆进行 “对搓"摊薄、“耙分”成束铺匀,并利用ADAMS软件对关键部件进行运动分析和参数确定。样机摊铺分束及编织试验结果表明:自动摊铺分束装置铺放秸秆厚度均值小于40 mm,满足后续编织要求;与平面式草帘编织机配套使用时,当机针针织频率f_z=0.8 Hz,编织速度v_b=90 m/h,设定摊铺装置对切机构的工作频率f_t=0.8 Hz,分束装置耙分机构的工作频率f_p=1.133 Hz,测得摊铺分束过程中秸秆的分束率...

Straw is a rich resource in quantity, but large amount of waste rice straw has been burned in the field, which causes waste of resource and environmental pollution at the same time. Straw is an important production resource, and the straw mats are widely used as a protective tool for bricks, buildings, agaric production and vegetable greenhouse, etc. According to literature and data reviewed, rice straw abroad is mainly used for field return and recycling, and straw mats braiding machine are rarely reported abroad. While in China, a type of mat...
