Description

Fine sand screening plant for construction Technical Field The utility model belongs to the field of building construction, and particularly relates to a fine sand screening device for building construction. Background In the building construction process, fine sand is taken as an important basic building material and is widely applied to links such as concrete stirring, mortar preparation, foundation treatment and the like. The indexes such as grain composition, mud content and the like of the fine sand have obvious influence on engineering quality. If large-particle impurities or coarse aggregates are mixed in the fine sand, pores or uneven strength can occur after the concrete is formed, and even hidden danger of engineering quality is caused. Thus, efficient screening of sand to obtain standard-compliant sand is one of the key steps to ensure the quality of construction. When traditional screening plant's material loading, the workman need use the spade to dig repeatedly and get the sand material in the sand heap, and through the arm lifting action with the spade lift to topple over behind the screen cloth, the workman need repeatedly dig for a long time sand, the lifting, the physical power action of toppling over, easily cause the workman tired, influence the construction progress, in addition, the planar design of traditional screen cloth easily causes sand material to pile up, makes large granule impurity or coarse aggregate pile up in the screen cloth middle part, reduces screening efficiency. Therefore, we propose a fine sand screening device for building construction to solve the above problems. Disclosure of utility model Aiming at the problems that the feeding workers of the traditional screening device need to repeatedly dig sand, lift and dump for a long time, the fatigue of the workers is easy to cause, the construction progress is influenced, and sand materials are easy to be piled up due to the planar design of the traditional screen, so that large-particle impurities or coarse aggregates are piled up in the middle of the screen, and the screening efficiency is reduced, the utility model provides a fine sand screening device for building construction. The fine sand screening device for building construction comprises a screw conveyor, an outer frame, a vibrating mechanism, a supporting frame and two springs, wherein the supporting frame comprises a lower fixing seat and four upright posts, a transverse strut and a guide rod are fixedly welded between the left upright post and the right upright post, the guide rod is arranged above the transverse strut, the lower fixing seat is fixedly welded between the left upright post, and a supporting seat is fixedly welded on the left side surface of the lower fixing seat; the frame is internally and fixedly provided with a splayed sieve plate for sieving sand, two sliding sleeves are respectively welded and fixed on the front side and the rear side of the frame, and the sliding sleeves are sleeved on the guide rod and can slide along the guide rod; The two springs are respectively sleeved on the two guide rods, and the springs are fixedly arranged between the sliding sleeve and the upright post; the bottom end of the screw conveyor is fixedly arranged on the supporting seat, a feeding hopper is arranged at a feeding hole of the screw conveyor, a discharging pipe is arranged at a discharging hole of the screw conveyor, and the lower end of the discharging pipe corresponds to the splayed sieve plate; the vibration mechanism comprises a driving component and a rotating shaft, the rotating shaft is rotatably arranged on the supporting seat, a cam is sleeved at the top end of the rotating shaft, and the cam is in contact with the outer frame; The driving component is connected with the rotating shaft and can drive the rotating shaft to rotate.
