Intermittent chemical drug feeding type shallow soil remediation device

Abstract

The invention relates to the technical field of regeneration of contaminated soil, and discloses an intermittent chemical drug feeding type shallow soil remediation device. The device comprises a rack; a vertical rod is fixedly installed in the rack; chemical drug containing boxes are fixedly installed between the left and right ends of the vertical rod and the rack; a sliding plate is slidably connected to the lower end of each chemical drug containing box; a discharging hole is formed in each sliding plate; a discharging groove is formed in the lower end of each chemical drug containing box;and a moving groove is formed in the lower end of each chemical drug containing box. According to the intermittent chemical drug feeding type shallow soil remediation device, the device is dragged bya machine to conduct soil turning operation on the contaminated soil, and then a soil turning roller rotates to turn the soil and drives a cam to rotate at the same time; when a protruding part of the cam is far away from a moving plate, a bent pipe rotates back through a guide rod, and meanwhile the upper end of the bent pipe moves relatively; a connecting rod drives a sliding rod to move; and the sliding rod drives each sliding plate to slide, so that the indirect discharging effect of each chemical drug containing box is achieved.

Description

technical field [0001] The invention relates to the technical field of regeneration of polluted soil, in particular to a shallow soil restoration device for intermittently injecting chemical drugs. Background technique [0002] With the development of society and economy, while a large amount of land resources are being occupied, the soil on many lands has been polluted. If the plants on the polluted soil enter our food chain, it will cause physical abnormalities in people who eat them. , so now soil remediation has become particularly important. At present, the remediation of contaminated soil refers to physical, chemical, biological, ecological principles, etc., and artificial control measures are used to reduce the concentration of soil pollutants. [0003] At present, the main use is to cover the contaminated soil by injecting chemical remediation agents into the contaminated soil, or directly use irrigation or spraying on the surface of the contaminated soil. However, i...
