China has a vast territory, complex terrain, and a wide variety of crops. The farming systems and planting habits vary from place to place. Agricultural machinery operations have strong regional characteristics. In agricultural farming, different regions have different requirements. For example, the northeastern region generally has dry ridges, and the plains are large, requiring agricultural machinery to have greater power for wide and high-speed operations. In the paddy field in the south, small, medium and light tractors (including machine farms) and their supporting agricultural machinery must be used for operation. The components such as wheel subsidence and bearings should be sealed to prevent muddy water from entering. For the same agricultural machinery, it is not necessarily usable in the South. Therefore, the design and selection of agricultural machinery must be adapted to local conditions. More than two continuous croppings or intercropping in North China require agricultural machinery to carry out joint operations of multiple types of work. In particular, paddy fields and dry land vary greatly in the agricultural technical requirements for farming. How to improve the adaptability of tillage machinery? As early as the early 1970s, under the call of “Achieving Agricultural Mechanization in 1980â€, the National Agricultural Machinery Department successively carried out series design of rake, rotary tiller and hoe in the south and north, and successively passed national technology. Identification, this has reached a relatively advanced level in terms of product performance, variety, degree of smelting and technical and economic indicators, and greatly improved the adaptability of tillage machinery.
China's self-designed southern paddy field (1LS) series of plows are all suspended ploughs, with six models. The plow body is divided into four types: five types: general-purpose plow body, scorpion type, tumbling type, and shattered soil type. Basically meet the matching needs of 20-75 horsepower domestic tractors. It can also meet the requirements of water and dry farming in paddy fields in the south. The single plow body is 20-25 cm wide and is suitable for 12-22 cm deep. There are two series of products in the north: the normal pitch medium plow (1L series) has six models, the tractor power is 20-75 horsepower, the connection mode is hanging and semi-suspended; the large pitch heavy plow (1LD) series has six models. The supporting tractor power is 54, 75 hp, and the connection mode is hanging type, semi-suspended type and traction type. Rotary tiller series products are divided into six grades of 1.00, 1.25, 1.50, 1.75, 2.00 and 2.25 meters according to different farming widths, a total of 14 models. Rotary tillers for workers and peasants - 12K hand-held tractors are widely used throughout the province.
There are nine models in China's southern paddy field (1BS) series. There are five power levels (ie 20-60 horsepower tractors) for supporting horsepower, and the connection methods are all hanging. The working width of the paddy field is 1.6, 1.9, 2.5, 3.0 meters. The structure of the cymbal has three types: star 耙, notched disk 耙 and double rolling 耙, and the depth is 10-17 cm.
There are nine models of the North series of disc harrows, supporting tractors 25-75 horsepower, and the connection methods include traction offset, traction opposite, semi-suspension offset and suspension offset. The width is 1.5-4.8 meters. Once deep, 10-20 cm.
