Efficient sand screening device for water conservancy project construction

Abstract

The invention provides an efficient sand screening device for water conservancy project construction, and relates to the field of water conservancy projects. The efficient sand screening device for water conservancy project construction comprises a machine body, a guide hopper, dispersion rods, a primary screening mechanism, an anti-blocking mechanism, a secondary screening mechanism and supporting legs, wherein the bottom end of the guide hopper communicates with the middle of the top surface of the machine body, the ends, far away from each other, of the dispersion rods are fixedly connected with the inner wall of the bottom end of the guide hopper, the top end of the primary screening mechanism is fixedly connected with the ends, close to each other, of the dispersion rods, and the top end of the anti-blocking mechanism is fixedly connected with the inner wall of the top end of the machine body. According to the efficient sand screening device for water conservancy project construction, a conveying hole and anti-blocking blades are arranged, firstly, the conveying hole can effectively convey medium sand filtered by a second filter hopper into a discharging cylinder, then the medium sand can be conveniently conveyed, then the anti-blocking blades can effectively clean the medium sand on the surface of the second filter hopper, and the speed of conveying the medium sand into the conveying hole can be increased.

Description

technical field [0001] The invention relates to the field of water conservancy projects, in particular to high-efficiency sand screening equipment for water conservancy project construction. Background technique [0002] At present, sand is widely used in the construction of various water conservancy engineering facilities. For the construction of some water conservancy engineering facilities, it is necessary to use a large amount of fine sand and cement for mixing and stirring, so as to facilitate the deployment of dikes that can resist rainwater erosion. However, in The directly mined sand is mixed with large grains of sand or crushed stones. The structure of the existing sand screening device is too simple, so that the functionality is relatively low, especially the existing sand screening device is not convenient for sand, large grains of sand and The gravel is separated from each other, which greatly reduces the quality of the screened sand, and the screening efficiency...
