青毛豆剥壳机的设计

摘要

目前，青毛豆剥壳机采用剥壳方式，大多用单对轧辊对毛豆进行剥壳，并且剥壳效率低，且籽粒破碎率较大。针对于此，本文设计了一种基于挤压剥壳原理，能调节多对轧辊转速、间距，并可对籽粒进行清选的青毛豆剥壳机。

此剥壳机的整体方案设计布置上采用三对轧辊剥壳机构，偏心振动机构驱动的鱼鳞振动筛和调节轧辊转速的无级变速装置，传动机构，电机和机架等组成。本机以漏斗状输入物料的形式设计布置，机架支撑着可调节物料的喂料斗，主要承担青毛豆荚的送料功能，主电动机布置于无级变速装置的下部，传动机构在机架的两侧，其剥壳过程是通过可调节转速和间距的剥壳轧辊对毛豆进行剥壳，剥出籽粒沿轧辊滚落入鱼鳞振动筛完成清选的过程。

该剥壳机构的性能技术指标：外形尺寸（长×宽×高）2257×1226×1211（mm）；轧辊数6只；轧辊直径67.5mm；轧辊间隙0.7～1.5mm；主电动机配套动力是1.1kW，生产效率200～600kg/h。其特点是：剥壳部分采用可传动用钢管；剥壳双辊采用啮合齿轮同步等速驱动；双辊表面附着一层橡胶滚花；轧辊的间距通过蜗杆传动和丝杆传动装置来实现，能满足不同尺寸的毛豆荚对剥壳间隙的要求。

Development of Green Soybeana sheller

Abstract

At present, green soy bean exhausted shell machine selects the exhausted shell method, mostly uses the list axis roller to carry on the exhausted shell to green soy bean,and efficiency of exhausted shell is low, also the broken rate is bigger. In view of this,this article designed one kind based on extrudeing the exhausted shell principle, could adjust rotational speeds of the axis roller, the spacing,and might carry on green soybean exhausted shell machine to the grain which can be elected.

This exhausted shell machine overall plan designed arranges three pairs of axis roller exhausted shells organizations, the bias vibrator unitactuation scale shaker and the adjustment roller rotational speed step less speed-change device, the transmission system, composition and so on electrical machinery and rack. This machine by the funnel shapein put material form design arrangement, the rack supports may adjust the material to feeding mouth, mainly undertakes green soybean feeding function, the main motor arrangement is in the steplessspeed-change device lower part, the transmission system in the rack two sides, its exhausted shell process is through adjusting the rotational speed and the spacing of exhausted shell roller to carry on the exhausted shell to green soybean, peels the grain to roll along the roller falls the process which the scale shaker completes clear elects.

This exhausted shell organization performance technical specification:The external dimensions (long * width * high) 2257×1226×1211(mm); Roller several 6; Roller diameter 67.5mm; Roller gap 0.7 ~1.5mm; The main motor necessary power is 1.1KW, production efficiency200 ~ 600kg/h. Its characteristic is: The exhausted shell partially uses may pass on uses the steel pipe; The exhausted shell axis roller uses the counter gear synchronization constant speed actuation; axis roller the surface is attaching a rubber knurling; The roller spacing realizes through the worm drive and the lead screw transmission device, can satisfy the different size the wool bean pod to the exhausted shell gap request.
