Sand screening machine for water conservancy project

Abstract

The invention discloses a sand screening machine for a water conservancy project. The sand screening machine comprises a layered sand screening machine main body and a bottom plate, wherein a discharging hopper is fixedly arranged at the lower end of the layered sand screening machine main body, an alarm device is arranged on the outer surface of the layered sand screening machine main body, a coarse sand vibrating screen is movably arranged in the layered sand screening machine main body, a fine sand vibrating screen is movably arranged below the coarse sand vibrating screen, a connecting pipe is fixedly arranged in the bottom plate, a fine sand output pipe is arranged at the lower end of the connecting pipe, and the discharging hopper is fixedly connected with the connecting pipe. According to the sand screening machine for the water conservancy project, the layered sand screening machine main body, the alarm device and the connecting pipe are arranged, so that coarse sand and fine sand can be screened in the same sand screening machine, people can conveniently know whether the sand screening machine works normally or not, the screened fine sand cannot be put into the water conservancy project for use in the first time, and the sand screening machine is suitable for different working conditions, and has a better application prospect.

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to a sand screening machine for water conservancy engineering. Background technique [0002] Water conservancy projects are projects built to eliminate water damage and develop and utilize water resources. Water conservancy projects need to use a lot of raw materials during construction, and sand is one of the indispensable raw materials. Therefore, in order to have enough sand for construction, scientists invented a sand screening machine to obtain enough sand for the construction of water conservancy projects and speed up the construction progress. However, the traditional sand screening machine occupies a large area, and there are too many devices in it, which wastes manpower and material resources. At the same time, the work efficiency is low, and it cannot meet the needs of various constructions for sand. Therefore, through continuous trial and research, the operati...
