Description

Technical Field

[0001] The utility model relates to the technical field of soil restoration, in particular to a saline-alkali soil crushing and restoration liquid mixing device. Background Art

[0002] Saline-alkali land refers to land with excessively high salt and alkaline content in the soil, which results in a decrease in the ability of plant roots to absorb water and nutrients, affecting their normal growth and yield. In the prior art, saline-alkali land soil improvement mainly involves loosening the saline-alkali land with a loosening machine, and then mixing the loosened soil with a repair agent using a soil improvement vehicle. This method requires two operating tools to be operated in sequence, resulting in low repair efficiency and poor mixing uniformity.

[0003] There are also some saline-alkali soil treatment and repair devices in the prior art, such as the Chinese invention patent with application number CN202410275748.6, entitled Humic Acid Soil Mixing Device for Saline-alkali Land Repair and Its Repair Method, which uses a rotating cylinder to drive multiple sets of blades to loosen the saline-alkali soil. At the same time, under the action of the second spiral conveyor, the humic acid inside the storage box is transported to the inside of the fixed cylinder through the connecting material pipe. Under the action of centrifugal force, the humic acid is discharged to the outside through multiple sets of discharge holes opened on the surface of the rotating cylinder. Since multiple sets of blades are loosening the soil at this time, the soil is in a dispersed state, and the discharged humic acid can be evenly mixed with the saline-alkali soil, thereby improving the saline-alkali land repair effect. However, it mainly releases humic acid by sowing.

[0004] The reapplication number is CN202322562678.6, and the name is a Chinese utility model patent for a repair device for saline-alkali soil treatment. It uses a water pump to introduce the repair agent inside the medicine box into the arc plate, and then the repair agent in the arc plate is sprayed out through multiple nozzles and sprayed on the soil in the screen barrel. Then the rotation of the screen barrel can drive the soil inside it to rotate slightly, so that the broken soil can be sprayed with the repair agent to a greater extent, so that crops can grow better and prevent the repair agent from evaporating in large quantities due to high temperature. However, it mainly uses the screen barrel to drive the soil to rotate, and uses the nozzle to spray the repair agent. The finely divided soil can easily enter the screen barrel to block the work of the nozzle, affecting the spraying effect of the repair agent. Utility Model Content
