Efficient sand screening device for construction site and using method of efficient sand screening device

Abstract

The invention relates to the technical field of building devices, and discloses an efficient sand screening device for a construction site and a using method thereof.The efficient sand screening device comprises a sand screening device body, the inner wall of the sand screening device body is rotationally connected with a sand screening roller, the upper surface of the sand screening device body is fixedly connected with a frame rod, and the inner wall of the frame rod is rotationally connected with a reciprocating lead screw; the outer wall of the reciprocating lead screw is in threaded connection with a blowing head, the inner wall of the blowing head is slidably connected with a sliding rod, and the two ends of the sliding rod are fixedly connected with the frame rods. According to the sand screening device, the air pump, the pipeline, the communicating assembly, the air blowing head and the like are arranged and used in cooperation, when the sand screening roller conducts sand screening, the air blowing head is inflated through the air pump, then air is blown to the sand screening roller through the air blowing head, and small sand grains clamped on meshes of the sand screening roller are blown off through air blown to the sand screening roller through the air blowing head; and small sand grains clamped on meshes of the sand screening roller are prevented from blocking sand screening of the device, so that the sand screening efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of construction devices, in particular to an efficient sand screening device for a construction site and a method for using the same. Background technique [0002] Before the mortar used in construction is mixed, it is necessary to use a sand screening device to screen the sand to avoid mixing larger sand and stones into the sand. There are many types of existing sand screening devices. Among the many sand screening devices, the drum type The sand screening device has a high sand screening efficiency. [0003] However, during the sand screening process of the drum sand screening device, the sand screening mesh on the drum sand screening device may block small sand particles, which in turn makes the small sand particles block the mesh. When the mesh on the sand screening device is blocked, the blocked The mesh will block the sieving of sand particles, which in turn reduces the efficiency of the device for si...
