Environmentally-friendly sand-stone separation device for large-scale sand and soil loading

Abstract

The invention provides an environmentally-friendly sand and stone separation device for large-scale sand and soil loading, and relates to the technical field of sand and soil loading devices. The environmentally-friendly sand and stone separation device is aimed at solving the problems that excavators are directly used by most of existing large-scale sand and soil loading devices for direct loading, but usually loaded sand needs to be screened to avoid mixing with stones, and pre-screening requires one process, and thus, manpower, material resources and time are wasted; existing loading devices on the market are mostly like the loading devices in the above patents, additional loading tools are needed for transporting the sand to the loading devices, and thus, the wasting of one process iscaused; and the existing devices are difficult to disassemble and transport, and are difficult to adapt to the changing environment of the transportation site. The environmentally-friendly sand and stone separation device comprises vertical frames which are mutually parallel and are vertically placed on the ground. As filtering transverse columns are uniformly arranged on a separation screen at intervals, the device is convenient to transfer for use, the step of separately screening sand before loading is saved, and material resources and manpower are saved.

Description

technical field [0001] The invention relates to the technical field of sand and soil loading devices, in particular to an environmentally friendly sand and stone separation device for large sand and soil loading. Background technique [0002] Before river sand or mining sand is used for transportation, it is usually necessary to filter stones before loading to ensure the quality of the sand. [0003] However, the existing loading devices are as many as a mining full-tailing filter cake warehousing loading frame in the patent application CN201920736881.1, including: feeding pipe, receiving hopper, first crushing roller and second crushing roller , the feeding tube is a cylindrical tubular structure, and the inner side of the feeding tube is embedded and rotated to connect with a screw feeding rod, and one end of the feeding tube is screw-fixed with a feeding motor, wherein the feeding motor is connected to the screw feeding rod through a coupling . In the utility model, by ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides an environmentally friendly sand and stone separation device for large-scale sand and soil loading, to solve the problem of existing large-scale sand and soil loading devices. The sand for loading needs to be screened to avoid mixing stones, and pre-screening requires a process, which wastes manpower, material resources and time. The existing loading devices on the market are mostly like the loading devices in the above-mentioned patents. The sand is first transported to the device through another loading tool, resulting in a waste of a process, and this type of device is difficult to disassemble and transfer, and it is difficult to adapt to the changing environment of the transportation site.
