Salt and alkali soil improvement device

Abstract

The invention belongs to the technical field of soil improvement equipment, and particularly relates to a salt and alkali soil improvement device. The salt and alkali soil improvement device comprisesa bottom plate, a moving module, a box body, a feeding opening, a crushing module, a chemical box, a spray head, a discharging opening and an armrest, wherein the moving module is arranged under thebottom plate; the box body comprises a main body frame and faceplates in left and right opposite arrangement; the main body frame is fixedly connected on the bottom plate; the faceplates can leftwardsand rightwards move on the bottom plate; a feeding opening is positioned at the top of the box body; the crushing module is positioned in the box body and is used for crushing and refining soil entering the box body; the chemical box is positioned at the top of the box body; the spray head is positioned in the box body, is arranged at the top of the box body, is connected with the chemical box through a pipeline and is used for spraying chemical powder in the chemical box into the soil; the discharging opening is positioned on the bottom plate, is in a funnel shape and is used for dischargingthe improved soil out of the box boy; the armrest is arranged at the right end of the bottom plate and is used for pushing the device to move.

Description

technical field [0001] The invention belongs to the technical field of soil improvement equipment, in particular to a saline-alkaline soil improvement device. Background technique [0002] Soil salinization is a worldwide problem faced by human beings. There are large areas of saline-alkali land in China, mainly distributed in the North China Plain, Northeast Plain, Northwest inland areas and coastal areas. The survival rate of plants planted in saline-alkali land is generally very low. low, thus affecting the agricultural and forestry production in our country. When there is too much salinity in the soil, salt damage will be formed, which will affect the normal growth of plants and cause plant death. Therefore, the reasonable improvement of saline-alkali land has become a major problem in our country. When alkaline land is improved, physical improvement is generally used. At this time, a crushing device is required. Because the soil quality of the saline-alkali land is rela...

[0002] Soil salinization is a worldwide problem faced by human beings. There are large areas of saline-alkali land in China, mainly distributed in the North China Plain, Northeast Plain, Northwest inland areas and coastal areas. The survival rate of plants planted in saline-alkali land is generally very low. low, thus affecting the agricultural and forestry production in our country. When there is too much salinity in the soil, salt damage will be formed, which will affect the normal growth of plants and cause plant death. Therefore, the reasonable improvement of saline-alkali land has become a major problem in our country. When alkaline land is improved, physical improvement is generally used. At this time, a crushing device is required. Because the soil quality of the saline-alkali land is relatively hard, the existing device cannot crush the soil material uniformly, thus affecting the protection of the saline-alkali land. In addition, most of the existing soil improvement devices are closed structures, and it is difficult to maintain the internal structure of the device in the later stage, which leads to a very low service life of the device
