A construction sand screening device

Abstract

The invention discloses a sand screening device for construction, which relates to the technical field of construction machinery, specifically a sand screening device for construction, including a fixed bin, a hopper, a reset rod, a screening device, a pressing rod, a guide plate, The first bearing, the roller, the second bearing, the transmission pipe, the bevel gear, the drainage pipe, the fixed rod, the electric motor, the connecting rod, the transmission rod and the stabilizer. The sand screening device for construction can lock the first fixed frame and the second fixed frame through the locking device, which can effectively prevent the second fixed frame from shifting during screening and cause uneven screening. The locking device can The misalignment adjustment of the first screen and the second screen allows the sand screening device to filter sand of various specifications, which can effectively enhance the scope of application of the sand screening device and solve the problem of existing sand screening devices. The ability to sieve sand with a fixed size makes the application range of the sand sieving device small.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a sand screening device for construction. Background technique [0002] The screening device is a vibration screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the sieve holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. Depending on the screen surface, the screen surface is divided into three types: grate, plate sieve and mesh screen. The grate is suitable for screening large particle materials, and the plate sieve is made of punched steel plate. The holes are round, square or rectangular, and have a long service life. It is not easy to block, suitable for screening medium particles. The mesh screen is woven or welded by steel wire. The holes are square, rectangular or long. The long mesh is suitable f...

AI Technical Summary

Problems solved by technology

[0003] The existing sand screening device has the ability to screen sand particles of a fixed size, which limits the scope of application of the sand screening device, and the anti-clogging ability of the existing sand screening device is relatively weak. After the amount of sand increases, the sand is easy to accumulate and cause the blockage of the sand outlet, which affects the screening efficiency of the sand screening device
