Soil pollution repairing material spreading device based on multi-layer spreading technology

Abstract

The invention discloses a soil pollution repairing material spreading device based on a multi-layer spreading technology. The soil pollution repairing material spreading device comprises a base plate,a material spreading box and a material storage box; the material spreading box is embedded in the center of the bottom plate, a material distribution plate is arranged on the bottom wall of the inner cavity of the material spreading box, multiple material distribution grooves are uniformly formed in the top end of the material distribution plate, the bottom ends of the material distribution grooves communicate with material spreading holes, and stirring devices are arranged in the material distribution grooves; multiple supporting rods are uniformly arranged on the edge of the top end surface of the bottom plate, and the top ends of the supporting rods are fixedly connected to the material storage box; and multiple walking wheels are uniformly arranged at the bottom end of the base plate. According to the soil pollution repairing material spreading device, the material stirring devices are arranged so that the material distribution grooves can be effectively prevented from being blocked by the material repairing material, and the excessive amount of the repairing material can be prevented from entering the same material distribution groove so that the repairing material can be uniformly dispersed in all the material distribution grooves; and the multiple material distribution grooves simultaneously perform material spreading so that the situation that the repairing material is not spread on part of soil can be effectively avoided; and uniform distribution nets is coordinated with the material distribution grooves for use so that the uniformity of the spreading of the repairing material can be ensured.

Description

technical field [0001] The invention relates to the field of soil spreading devices, in particular to a soil pollution remediation material spreading device based on multi-layer spreading technology. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their decomposition pr...
