Soil pollution restoration material spreading equipment based on blowing and spreading technology

Abstract

The invention discloses soil pollution restoration material spreading equipment based on a blowing and spreading technology. The soil pollution restoration material spreading equipment comprises a bottom disc, a material spreading box and a material storage box, wherein the material spreading box is embedded in the center of the bottom disc; the top end of the material spreading box is in throughconnection with a connection pipe; a material spreading plate is arranged under the material spreading box; a plurality of fixing rods and a plurality of discharging pipes are uniformly arranged on the top end of the material spreading plate; the left side end of the material spreading plate is uniformly provided with a plurality of material spreading holes; the right side end of the material spreading plate is uniformly provided with a plurality of support frame rods; the other ends of the support frame rods are rotationally connected with a windmill; the edge of the top end surface of the bottom disc is uniformly provided with a plurality of support rods; the top ends of the support rods are fixedly connected with a material storage box; the top end of the material storage box is communicated and connected with a feeding pipe; the bottom end of the bottom disc is uniformly provided with a plurality of walking wheels. Through the arrangement of the windmill, during the walking, the windmill rotates, so that the airflow near the material spreading plate becomes spiral airflow; the restoration material discharged from the material spreading holes can be blown, so that the restoration material can be spread in the fixed direction; therefore the spreading quality of the restoration material can be greatly improved.

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 blowing 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 products will gr...

AI Technical Summary

Problems solved by technology

[0006] With the development of science and technology, many soil remediation materials have been developed, so how to spread the remediation materials evenly in the soil requires some auxiliary equipment, such as spreaders, etc., because the particle size of the soil remediation materials is small, The existing spreading mechanism cannot fully meet the requirements of soil remediation, and the spreading is often uneven, and part of the spreading is not enough, which greatly reduces the effect of soil remediation, and it is difficult to meet the needs of modern soil treatment.
