In recent years, with the country's increasing emphasis on agricultural production, grain production has steadily increased. However, in many places, people are still accustomed to using traditional farming methods for agricultural production, resulting in long-term exposure of the surface in spring and winter, which will lead to serious loss of organic matter and water in the soil surface in many areas, thus exacerbating soil barrenness. and deterioration of the ecological environment. At the same time, due to the long-term absorption of a large amount of land nutrients, the fertility of farmland and ten soils tends to decline, and the ten lands cannot get a good recuperation, which leads to the gradual deterioration of the agricultural ecosystem and seriously restricts the further increase of my country's grain production.
      As a large agricultural country, agricultural mechanization is the basic direction of agricultural production development. With the continuous reform of the agricultural industrial structure, small agricultural machinery can no longer meet the requirements of agricultural production. The multifunctional land preparation machine, which is composed of working parts and devices with multiple functions reasonably and effectively, has become an increasing research direction. In this way, the whole machine has compact structure, complete functions, good maneuverability and operability, and can improve economic benefits. Heavy Rotary Cultivator completes multiple operations at one time, reduces the number of machine operations, avoids soil compaction and damage to soil structure, absorbs soil moisture and nutrients, reduces energy consumption, saves energy time and fuel costs, thereby reducing operating costs: it has strong practicability . For example, SGTN210 Stubble Farmland Rotary Tille can complete stubble pulling, plowing, suppression, ridge cultivation, fertilization and other operations at one time. Strong practicability, wide application range and strong crushing capacity. After one operation, the next operation can reach the state of preparing to seek the path, which reduces the cultivation cost of ten soils, significantly improves the operation efficiency, and reduces the compaction and damage to ten soils (2). This paper mainly designs the whole machine for the multi-function soil preparation machine, especially the design of the transmission system and key components. The Rotary Tiller part is one of the main working parts. Nomadic farming has the function of plow and harrow. One rotary tillage can reach ground level.

ROTARY TILLER

A range of models are available to suit tractors of all sizes.
The side drive system increases durability and makes complete tilling a certainty.
With the perfectly waterproof mechanism, it can be used in paddy fields.
The spring-loaded trailing boad is fully adjustable.
There is a full range of blades for all types of fields.
Attachments such as the ridger, mulcher and seeder make it not only multi-purpose but also very economical.
The three-point hitch linkage simplifies adaptation to any tractor.
Durability is further increased by more effective fixing of blades to the flange.
The universal joint is a standard attachment.
