Carbon dioxide expanding and soil loosening device and method

Abstract

The invention relates to a carbon dioxide expanding and soil loosening device and a carbon dioxide expanding and soil loosening method. The device comprises a pipe body and a conical head; a cavity filled with liquid carbon dioxide is formed in the pipe body; the conical head is hermetically arranged at the gas outlet end of the pipe body; a gas channel is formed in the middle part of the conicalhead; the gas channel is communicated with a gas outlet of the pipe body through a pressure valve arranged on the gas channel; and at least one group of jet holes are arrayed in the conical head alongthe axial direction of the conical head. The method comprises six steps of distributing points, embedding pipes, connecting lines, stimulating, checking and rolling up. According to the device and the method, the depth of the loosening soil layer can be selected, the soil layer with the needed depth realizes uniform and integrated fluffing and the soil structure is improved; meanwhile, the deviceis lightweight, small in volume and convenient to operate and avoids the defect that large machinery rolls the soil.

Description

technical field [0001] The invention relates to a carbon dioxide expansion soil loosening device and method. Background technique [0002] Soil compaction is a common phenomenon in the farming process of farmland, orchard, grassland, and vegetable garden, and is an important obstacle to soil degradation, soil quality decline, and unsustainable soil productivity. Soil compaction is mainly related to factors such as heavy soil texture, shallow plowing layer, low organic matter content, excessive application of chemical fertilizers, and compaction by mechanical tillage. Soil loosening is an important technical measure to eliminate or alleviate the problem of soil compaction. Increase the gap between soil particles by loosening the soil, make the soil loose, improve soil aeration, increase the respiration of root cells, promote the exchange of mineral elements between root hairs and soil and the absorption of mineral elements by roots; at the same time, for soil microorganisms ...

AI Technical Summary

Problems solved by technology

For example, the soil loosening machine mainly uses the probe to form small holes on the ground. Although it is beneficial for the water on the soil surface to flow to the deep soil through the needle holes formed by the hole drilling, this technology does not change the soil porosity and soil porosity in essence. Tightness to achieve the purpose of real loose soil

Excavator-type rippers or bulldozer-type rippers need to connect the ripper device with power traction equipment to work, and are generally bulky and heavy. It is easier to work on open and flat ground during the land fallow period, but it is difficult to work on small or finely crushed land. Loosen the soil on uneven land and land with plant growth. At the same time, there may be compaction of the soil during large-scale mechanical operations, which will further aggravate soil compaction.
