稻草水洗撕裂机撕裂机理研究

Studies on working mechanism of tearing machine for washing rice straw

以稻草作为食用菌培养料生产食用菌在食用菌行业早已发展起来,但缺少相应的设备。设计了一种以稻草为原料生产食用菌菌基的设备—稻草水洗撕裂机,对稻草水洗撕裂机的结构、工作原理作了介绍,对稻草水洗撕裂机的撕裂机理进行了探讨,对撕裂刀的工作过程进行了说明,建立了撕裂刀片等滑切角几何模型,并对稻草在撕裂机内的运动进行了分析。结果表明稻草水洗撕裂机结构合理、零部件设计正确、运动过程符合实际,使以稻草为原料生产食用菌成为可能。

With development of straw mushroom as edible fungus production of culturing materials in the mushroom industry,the lack of appropriate equipment is found.An equipment for producing bacteria-based edible mushroom is designed by taking rice straw as raw materials—tearing machine for washing rice straw,in which the structure,working principles of the machine were introduced and the working mechanism was explored as well.Meanwhile the working process of the tearing knife was introduced,and a geometrical model for sliding-cutting angle of the knife was established.In addition the motion of the straw inside the machine was analyzed,which results show that the structure is reasonable,the component design is correct,the movement is practical.Thus it is possible to produce edible mushroom with rice straw.
