Key words: compound reduced tillage soil preparation machine； Tillage machinery； Disc harrow. In recent years, the agriculture is faced with energy crisis, waste of resources, population increase, arable land decrease, soil fertility decline, the rise in the cost of ecological imbalance, environment pollution and the grim situation, all countries in the world in the corresponding countermeasures and agricultural development strategy, put forward the agricultural sustainable development is given priority to with deep loosening body of conservation tillage technology such as no-till less. In all the countermeasures, and the development direction of farming machinery as a strategic priority. Western developed countries began to develop in the early 1970 s and expansion, to adapt to the high yield and agronomic requirements of new agricultural machinery research and development reduce cost increase efficiency and maintain ecological environment and conservation tillage technique and form a complete set of machines and tools. Traditional tools based on constant innovation in structure: to increase the furrow plough the soil properties, continuation to huasheng body； Prior to plough devices with small plough or coulter, reduce machine work resistance； With the hydraulic oil cylinder tillage amplitude adjustment and suspension frame transverse position, in order to increase its adaptability； After a plough body can be folded upwards to reduced tillage, flip agencies add pin set device； Deep furrow plough and loose on the device is equipped with various forms of security； Disc harrow Angle adjustment and frame of the folding wing with a hydraulic oil cylinder control, some disc harrow products w ith lateral transport device； Will deep loosening and ploughing up organic knot together, make the soil to flip up and down inside the top 20 cm, lower deep loosening between 20 to 35 cm； In order to improve the vehicle performance, in the deep loose handle on add a layer or two layers of wings shovel, soil to form the upper finely, and lower the actual situation, for the growing of crops, and provides a good soil conditions,Is conducive to crop growth. National large and medium-sized tractors became more perfect, has increased year by year. Huasheng plow, disc harrow, and deep loosening machine towards traditional tools such as product with 147 kw or more large and medium-sized tractors with increase direction, perfect structure and function. Plowing machinery to adapt to various soil conditions, and to meet the needs of different farming system development, thus must continually develop new working parts. Study: big company attaches great importance to working parts in the furrow plough on before using various types of plow body surface and small plough； On disc harrow adopts various curvature radius, diameter and shape on the disc harrow piece； Driven tillage and soil preparation machine is a wide variety of working parts. On the same machine, through the replacement parts to adapt to changing working conditions, thus expanding the function of products, improve the adaptability of region, the engine and reduces the users upgrade. Its working parts are standard, standardization and mass production. With the research and production of farming machinery, rate of tractor is widely used, especially the difference led to tillage machinery development to the direction of more varieties and series, wide, high speed and high efficient low consumption direction development, to the electronic monitoring, hydraulic pressure and high and new technology such as modularized design direction. With matching plow land preparation, therefore, mechanical products, also continues to broaden the scope of form a complete set with the tractor, minimize component types and structure, by helping to improve the degree of standardization, seriation and generalizing to meet market demand. 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. Make industry, according to different cropping system and different conditions of soil and agronomic requirements, reasonable piece together, form a different form of job function, can improve the utilization rate of machine tools by more than 50%. Joint rig combination, therefore, is the developing direction of the joint operation equipments abroad in recent years, the main rig has: tillage soil preparation combined operation equipments, deep loosening stubble ploughing combined operation equipments, deep loosening rake joint rig and plowing fertilization seeding joint operation equipments, etc. Along with our country power tractor has increased year by year, demand for joint operation equipments will increase. Do as a result, working parts to develop a variety of combinations of joint operation equipments, also want to develop/points can close 0 matched stack joint operation equipments. Liquid mechanical and electrical integration technology will be widely used on all kinds of farm machines and tools, such as according to soil conditions automatically adjust the machine parameters and operating status, change the machines overall size, and drives the working parts and so on, will be more use of hydraulic components.
