Soil sieving and crushing device

Abstract

The invention discloses a soil sieving and crushing device. The device contains a bracket which is of an L-shaped frame structure, wherein a hopper and a vibrating sieve are arranged at the top end of the bracket; a filtering sieve, a supporting spring, a fifth motor and a cam shaft are arranged at the bottom end of the vibrating sieve; a guide groove is formed below the hopper; a slope-shaped platform is arranged on the middle lower part of the bracket; a sieving drum, a first motor, a second motor, a rolling wheel and a gear are arranged on the slope-shaped platform; the sieving drum consists of an outer cover, a sieving outer drum and a sieving inner drum; the sieving inner drum is driven by the second motor; the sieving outer drum is driven by the first motor; a conveying belt and a third motor are arranged on the bracket below the front end of the sieving drum; a rotary-cutting and rolling hammer device with a rolling hammer device and a rotary-cutting device is arranged at the front end of the conveying belt; the rotary-cutting and rolling hammer device is driven by a fourth motor. The electromechanical structure provided by the invention can finish work, such as quickly crushing and sieving soil, automatically adding medicine, mixing, stirring and the like, and is the relatively effective mechanical crushing equipment used for treating heavy metal pollution soil.

Description

technical field [0001] The invention relates to the technical field of mechanical crushing devices, and relates to equipment for crushing and screening soil, in particular to a soil screening and crushing device. Background technique [0002] In modern society, if we do not pay attention to the protection of the environment while developing industry, it will cause environmental pollution. The soil, water environment, and air that human beings rely on for survival will all be affected. Therefore, people are paying more and more attention to environmental protection, and the content of the environmental protection industry is becoming more and more extensive. [0003] At present, in the treatment of soil polluted by heavy metals, adding liquid or solid agents to the polluted soil to prevent the expansion of pollution and actively improve the soil is one of many treatment methods. In order to achieve a better treatment effect on the soil, it is necessary to break the soil and...
