Soil improvement machine and soil improvement method

Abstract

The invention discloses a soil improvement machine. The soil improvement machine comprises a tractor, a deep ploughing device, a material applying device and a flattening device, wherein the deep ploughing device, the material applying device and the flattening device are fixedly arranged on the tractor and are sequentially arranged in the advancing direction of the tractor. The method comprises the following steps that: firstly, soil is turned up and enters a mixing box, and the soil is cut and raked step by step, so that soil blocks in the soil become small and loose, and chemical adding isfacilitated; chemical adding improvement is carried out on the soil while cutting and raking are carried out, and chemical adding comprises solid materials and liquid materials, so that the liquid adding requirements of different improvers can be met; and after the soil is cut, raked and mixed with added liquid, the soil is flattened by the flattening device, so that later soil fertilization and cultivation are facilitated. According to the soil improvement machine, the improvement operation of the soil is convenient, the improvement effect is good, all the procedures are automatically completed by the machine, the improvement working efficiency is high, and the soil improvement machine is suitable for large-range and large-area soil improvement work.

Description

technical field [0001] The invention belongs to the technical field of agricultural ecology, and in particular relates to a soil improving machine and a soil improving method. Background technique [0002] In recent years, with the rapid development of my country's industrialization, the soil has been continuously damaged by various pollutions. According to statistics, at present, 20 million hectares of cultivated land in my country are polluted by heavy metals, accounting for about 1 / 5 of the total cultivated land area, and this has also brought many impacts on the lives of the people. Soil pollution mainly refers to the excessive organic waste or toxic waste contained in the soil, which affects or exceeds the self-purification ability of the soil, thus producing harmful effects on hygiene and epidemiology. Pollutants can enter the soil through a variety of ways, causing changes in the normal function of the soil, thereby affecting the normal growth and development of plan...

Problems solved by technology

Once soil pollution occurs, it is often difficult to recover only by cutting off the pollution source. The refractory pollutants accumulated in the polluted soil are difficult to eliminate by dilution and self-purification. The cost of treating polluted soil is usually high and the treatment cycle is long. At present, we can only rely on soil replacement, leaching soil and other ways to control the pollution problem, and there is no other effective treatment technology

[0003] Existing soil improvement machines basically achieve soil improvement by excavating and loosening the soil surface. In order to better improve the soil, some machines mix the excavated soil and materials, and then respread the soil into the land Among them, some machines input soil conditioner into the loosened soil, but generally the excavated soil is of different sizes, and the simple mixing effect is not good, and these machines need to use other traction machines to move around. The functions are relatively simple, the application is limited, and it cannot be promoted and used
