Blocky coarse sand screening device used in construction sites

Abstract

The invention discloses a block coarse sand screening device for a construction site, which comprises a base, a material spreader, a top plate, a first rotating shaft, a second rotating shaft, a feeding barrel and a sand screening barrel; the upper side of the feeding barrel Fixedly installed on the lower side of the top plate, the lower end of the feeding barrel is rotated and installed with a rotating cylinder; the lower end of the rotating cylinder is fixedly connected with a material spreading plate; the feeding barrel is provided with a feeding port; the bottom plate of the material spreading plate A number of discharge holes are evenly opened on the top; the sand screening box is a circular structure with an upper end opening, and the sand screening box is located below the material spreading tray; the inside of the sand screening box is sequentially provided with fixed sieve plates and movable screens from top to bottom. sieve plate. The invention is provided with a particle board, a rotating cylinder and a material spreading plate, and a heating wire is arranged on the inner wall of the rotating cylinder, which can effectively improve the screening efficiency of massive coarse sand and improve the sand screening effect; it is also provided with a fixed sieve plate and a movable The sieve plate can not only control the particle size of the discharged fine sand, but also facilitate the discharge of coarse sand.

Description

technical field [0001] The invention relates to sand screening equipment, in particular to a block coarse sand screening device for construction sites. Background technique [0002] A construction site is a place where construction projects are being developed and civil engineering is being carried out. Its scope is often closed by hoardings, barbed wire or walls to restrict the entry and exit of personnel, materials, machinery and vehicles. There are property management administrators guarding. You may need to register your identity and wear a helmet when entering and exiting. [0003] During the construction of the building construction site, sand is used, and the sand cannot be used directly when it is bought back. The sand needs to be sieved. The sand treatment effect is not good, and due to transportation and other reasons, the sand is easy to be damp and agglomerated. The existing screening device has low screening efficiency for blocky coarse sand, and the screening...

Problems solved by technology

[0003] During the construction of the building construction site, sand is used, and the sand cannot be used directly when it is bought back. The sand needs to be sieved. The sand treatment effect is not good, and due to transportation and other reasons, the sand is easy to be damp and agglomerated. The existing screening device has a low screening efficiency for blocky coarse sand, and the screening effect is poor, which is likely to affect the construction quality.
