Soil remediation impurity screening device

Abstract

The invention discloses a soil remediation impurity screening device. The soil remediation impurity screening device comprises a groove plate, the bottom of the groove plate is fixedly provided with abottom plate, and one side of the groove plate, which is away from the bottom plate, is provided with two long bar-shaped through grooves which are parallel to the bottom plate; a second slider is slidingly arranged inside one of the through grooves, a first slider is arranged inside the other through groove, both sides of each slider are fixedly connected with mounting columns, which are provided with springs in a sleeve mode, both ends of every spring abut against the side surface of the corresponding through groove and the side surface of the corresponding slider; the side surface of the second slider is provided with a crank in a penetrated and hinged mode, and a connecting rod is hinged to one end of the crank, which is away from the second slider. The soil remediation impurity screening device is novel in structure and can achieve rapid screening action by changing the distance between the two sliders through the crank and the connecting rod, thereby being simple and compact instructure; meanwhile, the springs enable the screening action of the entire soil remediation impurity screening device to be smooth and higher in efficiency.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to an impurity screening device for soil restoration. Background technique [0002] With people's increasing awareness of environmental protection, soil remediation is the top priority of the current environmental protection task. In the process of soil remediation, it is inevitable to screen and separate impurities from heavily polluted soil, and most of the current screening work is It is completed by large-scale machinery, which requires a lot of power consumption. At the same time, this type of device has a high one-time investment, which hinders the development of small enterprises and restricts the development of the soil remediation industry. For these large-scale equipment It occupies a large area and has poor mobility. It can only operate with the equipment as the center, and cannot easily transport the equipment to the polluted site. In addition, this type of equipment has ...
