| In order to improve the ecological environment of arid and semiarid areas in north China, contain desertification extension momentum and management work of soil and water loss in the passive situation, we need to effectively improve rainwater harvesting mechanization technology of vegetation restoration. Tilting the plough digging machines is a kind of digging holes rainwater harvesting machinery, forestry equipment on it by digging and scale-hole can better will make full use of limited natural rainfall, can not only improve the effect of soil physical and chemical properties, but also play a rainwater storage keep moisture increase soil moisture, prevent water loss and soil erosion, improve the survival rate of planting.According to the specifications of forestry afforestation modes of soil preparation and scale-hole, the catchment afforestation digging machine-tilting plough type design of digging machines; Introducing the tilting and scale-hole earth auger overall plan research, this paper expounds the working principle and composition of the whole machine; having a study on design of main structure for tilting and scale-hole earth auger/Using 3 d graphics software Pro/E draws the 3 d design; Through the field of mechanical dynamics parameters of telemeter field traction resistance test was carried out on the prototype, the deep loosening shovel, deep loosening knife, the level of the plough bottom frame traction resistance, mechanical parameters, such as rod on the traction Angle, and the horizontal resistance calculation in theory, by contrast, the article expounds the theory level caused by traction resistance were measured and the actual level of traction resistance the cause of the error; According to the measured horizontal traction resistance of tilting and scale-hole a major part of the earth auger for finite element analysis, testing and verifying the reliability of design, providing certain reference for further optimization design. |
