Mechanical sand screening device for construction

Abstract

The invention discloses a mechanical sand screening device for construction. The mechanical sand screening device comprises a frame, a feeding port is formed in the frame, four rollers are arranged at the position, close to the feeding port, of the frame, rotating shafts are arranged on the four rollers in a penetrating mode, the rotating shafts are rotationally connected with the frame through bearings, gears are installed on the rotating shafts, a chain is arranged on the outer sides of the gears, the multiple gears are in transmission connection through the chain, a slider-crank mechanism is arranged at the ends of the rotating shafts, an automatic sand screening mechanism used in cooperation is arranged below the slider-crank mechanism, a driving mechanism used for driving any roller to rotate is arranged at the bottom of the frame so as to be different from the prior art, in the real-time use process, due to the use of the rollers, so that the feeding port is not prone to being blocked, material conveying is smoother, the rollers are used in cooperation with an existing sand screening drive, the use cost of the equipment is effectively controlled, stable and efficient sand feeding and screening are guaranteed, and therefore real-time, efficient and stable sand screening use is effectively facilitated.

Description

technical field [0001] The invention relates to the technical field of building material screening, in particular to a mechanical sand screening device for construction. Background technique [0002] With the continuous progress of society, the machinery industry is also developing rapidly, and a large number of industrial tools are produced and used. With the extensive development of the construction machinery industry, in the construction industry, sand and gravel are used as an The operation of the sand sieving machine is inevitable. When using sand, since there are more large-grained stones in the sand in the natural state, it must be screened before use to remove the larger particles in the sand. [0003] However, during the screening process, the debris in the sand is easy to accumulate at the feed inlet, and the material flow is not smooth, resulting in a decrease in screening efficiency and the inability to efficiently complete the sand screening work. Therefore, we ...

[0003] However, during the screening process, the debris in the sand is easy to accumulate at the feed inlet, and the material flow is not smooth, resulting in a decrease in screening efficiency and the inability to efficiently complete the sand screening work. Therefore, we propose a mechanical screen for construction sand device
