Study On The Cutting Properties And Cutting Tool Of Caragana

Caragana is a very important kind of desert shrub resource, which is very abundant in Inner Mongolia. Its ecological value and economic value are both very high, it is not only the excellent wood specie to prevent wind and fix sand, but also the high quality raw material to produce wood-based panel. However, the traditional cutting machine can't meet the demand of cutting, because of the properties of Caragana and its growing circumstance. At present, Caragana is cutted mainly by man power, there isn't perfect cutting machine. The paper investigated the status of desert shrub in the west of Inner Mongolia and its cutting, the physical mechanics properties were tested. Though the simulate cutting experiment of single tooth of round saw, the cutting force of Caragana was tested, the relationship between feeding size of single tooth and cutting force was confirmed, the analysis model of Caragana cutting power was established, the relationship between feeding size of single tooth and cutting power was assured, which provide theory basis for the design of cutting tool. The research results showed: There exited linearly relationship between feeding size of single tooth and cutting force, cutting power, with the increasing of feeding size of single tooth, cutting force and cutting power enhanced; When Caragana cutting productivity is 30cm2/s, the cutting power of cutting tool is 0.73kw,which is gained from the relationship of feeding size of single tooth and cutting power. A new design thought was proposed: the design technique which use the power output axis of tractor as the origin of power, furthermore, a Caragana cutting machine was primary designed.
