Because driven machines and make full use of the tractor power, can control effect on soil strength, can satisfy various work requirements, the company has attached great importance to driven the soil preparation machine product development and production. At present, the existing rotary plough, power shovel, rotary cultivator and power harrow tillage soil preparation machine use more power output shaft of the tractor, through mechanical transmission drivers working parts. At the same time, also study produced by the tractor pto drive hydraulic system, driven by hydraulic motor and working parts of the new type plow soil preparation machine. Existing driven tillage soil preparation machine mainly include the rotary tiller and stubble machine, etc, are powered by the tractor power output shaft, drive the rotary working parts to complete the machine operation. No-till deep loosening technique has reduced machine off the machine working resistance and improve working efficiency and reduce the work intensity of the soil characteristics, the formation of the actual situation, using a combination of arable layer soil structure. Imaginary part of the aerobic bacteria thrive, provide sufficient nutrients for crops, beneficial to crop growth, the ground water is large by virtual part will infiltrate into underground water points on the surface of the earth, to prevent surface runoff, use； Real part of the bacterial growth is conducive to idle, keep the nutrients in the soil, raise. Drought, via the real part of the soil capillary effect, will absorb on the surface, groundwater supply crop water, realized the combination of land and ground. Therefore, in order to reduced tillage, deep loosening instead of plough tillage technology have the widespread application in many countries, one of the key technologies for conservation tillage. In order to adapt to the needs of agricultural production, the company pays much attention to the deep loose working parts and tools. To improve the operation quality and the low resistance reduction, developed a variety of forms of bar type deep loosening shovel. On the deep loosening machine overall structure and continuous innovation, to develop the deep loose joint operation equipments at the same time. at present, the research and production, from the structure can be divided into the close combination of rig and combination joint rig: tight tight type joint rig is the organic combination of the operational functions, reasonable configuration, according to the whole machine is one of the forms to form an independent complete machine type, its unit design is reasonable, compact structure, reasonable and tractor kit, is advantageous to the tractor mounted homework； Combination type joint rig is used/group with 0, the separate machine constitute joint operation equipments.
