Combined deep scarification and land preparation machine

Abstract

The invention relates to a combined deep scarification and land preparation machine which is characterized by comprising a rack, a full-direction deep scarification device and a turnover device, wherein the turnover device is arranged in front of the full-direction deep scarification device; the rack consists of a front beam, an upper suspended plate, lower suspended plates, transverse beams, fixed transverse beams, fixing plates, limiting plates, a rear beam and support beams; a partial deep scarification device is arranged on the rear beam; a soil crushing depth limiting device is arranged behind the support beams. According to the combined deep scarification and land preparation machine, a shallow layer and a conventional tillage mellow soil layer are loosened by using the turnover device, subsequently deep soil is cut by using the full-direction deep scarification device and is crushed by using the partial deep scarification device, furthermore the ploughed soil is crushed and flattened by using disc cutters in the soil crushing depth limiting device. In a word, by adopting the combined deep scarification and land preparation machine, combined soil preparation, shallow layer turnover operation, single full-direction deep scarification operation and partial deep scarification operation can be achieved according to agricultural requirements of different crops, the effect of one-machine multi-functions is achieved, the resistance can be reduced, the energy can be saved, and a good operation effect can be achieved.

Description

technical field [0001] The invention relates to a combined subsoiling machine. Background technique [0002] The cultivated land has been prepared by plowing or rotary tillage for a long time, resulting in thinning of the cultivated layer, compaction of the soil, increasing soil specific resistance year by year, and the need for more and more farming power. The widespread use of large-scale agricultural machinery such as high-horsepower tractors further intensifies the compaction of the soil, leading to a vicious circle, which makes the cultivated land form a thick and hard plow bottom layer. The existence of the plow stratum reduces the capacity of the plow layer and deteriorates the soil structure; it leads to more serious surface runoff and soil erosion, weakens the water storage capacity, and depletes farmland fertility; reduces soil porosity, limits the growth and development of plant roots, and reduces the stress resistance of crops , which restricts high and stable p...

Problems solved by technology

[0003] The problems existing in the existing soil preparation machinery are: the operation depth of the traditional rotary tillage machinery is small, and the long-term shallow tillage makes the soil form a thick and hard plow layer; the traction resistance of the deep tillage machinery is too large, and a high-horsepower tractor is required Traction, excessive energy consumption, increases the economic burden of farmers, on the other hand, deep plowing machinery will plow the deep soil to the surface, destroying the original soil plow layer structure, which is not conducive to crop growth

According to the nature of the operation, mechanized subsoiling can be divided into two modes: omnidirectional subsoiling and partial subsoiling. However, all-round subsoiling has a large amount of disturbance to the soil, and there is a large amount of water evaporation. During the subsoiling process, such as working resistance Large, too much energy consumption; local subsoiling has little disturbance to the soil, but subsoiling operation is difficult to ensure that the soil after subsoiling meets the requirements of flat field surface, finely broken soil, and consistent plowing depth
