Abstract

The invention discloses a soil sample crushing and screening device for soil restoration. The soil sample crushing and screening device comprises a fixing seat, an upper cover plate, a driving motor,a special-shaped gear, a screening box and a crushing box, the screening box is welded to the lower end of a connecting rod, a screen is arranged at the bottom of the screening box, and a plurality ofgroups of crushing wheels are further arranged inside the screening box. Intermittent electrification and power loss of an electromagnet are realized so that the screening box can move up and down intermittently, the vibration effect is achieved, the screening speed is greatly increased, and meanwhile, the situation that soil particles block holes during screening is effectively avoided; and thescreening box can slide left and right, so that up-down and left-right translation motion is realized, then the screening speed is further increased, meanwhile, compared with manual screening, time and labor are saved to the greater extent, moreover, the structure is simple, the manufacturing cost is greatly reduced, and the practicability is high.

Description

technical field [0001] The invention relates to a grinding device, in particular to a soil sample crushing and screening device for soil restoration. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless ...
