链式小型林业原条输送装备的设计

Design of the Chain-type Small Forestry Original Conveying Device

采用AutoCAD工作软件设计了一款链式小型林业原条输送装备,并对其中的关键机构的设计与计算过程进行了翔实表述。按该设计方案制造出的链式原条输送机采用链条传动,与带传动相比,无弹性滑动和打滑现象,平均传动比准确,工作可靠,效率高;该机械传递功率大,过载能力强,相同工况下的传动尺寸小;所需紧张力小,作用于轴上压力小。同时,采用特殊滚筒式输送平台,不仅对原条起到了导向作用,而且可减少原条在行进过程中的左右方向上的移动,有效地降低了能耗,提高了生产效率。该设备能在高温、潮湿、多尘、有污染的恶劣环境下工作,适合于林区环境工作。

AutoCAD was used to design a chain-type small forestry original conveying device,the design of key structure and calculation process was elaborate in detail. The chain-type original conveying device is accurate,reliable,high efficiency without elastic slip and skid phenomenon compared with traditional belt transport device; the transmission power is large and overload capacity is strong. Meanwhile,a special roller conveyor platform not only can guide the original band,but also can reduce original band movement at left and right direction, which will effectively decrease the energy consumption and improve production efficiency. The equipment can be used in severe environment of high temperature,damp,dusty and pollution.
