Embodiment 1

[0023] see Figure 1~2 , in an embodiment of the present invention, a high-efficiency sand screening device for building construction, comprising a sand screening box 5 and a screen 6 fixedly installed in the sand screening box 5, the sand screening box 5 is installed above the bottom plate 1, and the sand screening box 5 The top of the box 5 is connected with a sand inlet pipe 14, and the bottom of one side of the sand screening box 5 is provided with a first discharge port 4, and the bottom of the sand screening box 5 is inclined to the first discharge port 4 to facilitate discharging. 1. Rollers 21 are evenly and symmetrically installed on the bottom. The rollers 21 are self-locking rollers to facilitate the movement of the device. The bottom plate 1 is pierced with a threaded drill rod 2 for fixing the entire device. The threaded drill rod 2 and the bottom plate 1 Threaded connection, the top of threaded drill rod 2 is welded and fixed with a first rocking handle, and a sh...

Embodiment 2

[0026] see image 3 The difference between the embodiment of the present invention and embodiment 1 is that further, in order to reduce the problems caused by the wear of the brush on the brush bar 7, the brush bar 7 is fixed on the bottom end of the installation rod 22, and the installation rod 22 is inserted into the socket provided on the drive rod 8, and a compression spring 23 is connected between the end of the drive rod 8 and the top of the socket, and the elastic force of the compression spring 23 pushes the installation rod 22 and the brush bar 7 to compensate for the wear of the brush .

[0027] The working principle of the present invention is: when working, start the drive motor to drive the drive shaft 10 to rotate, the drive shaft 10 drives the drive disc 11 to rotate, the drive disc 11 drives the drive rod 8 to swing through the first cylindrical pin 12, and the drive rod 8 drives the brush bar 7 swings, and the brush bar 7 constantly brushes the screen cloth 6...

Abstract

The invention discloses a high-efficiency sand screening device for building construction, comprising a sand screening box and a screen fixedly installed in the sand screening box, the sand screening box is installed above the bottom plate, and a brushing assembly is arranged above the screen, The assembly includes a brush bar and a drive mechanism for driving the brush bar to move. The screen is arranged in a concave arc shape. The drive mechanism includes a drive shaft, a drive disc and a drive rod. Shaking unit, the shaking unit includes a shock absorbing spring, a second motor, an adjusting screw and a shaking piece. This application is equipped with a brushing assembly, and the brush strips continuously brush the screen, which can help to brush the screen to prevent the screen from being blocked , at the same time, it can sweep the sand larger than the mesh hole on the screen to the second discharge port, and automatically discharge the material to prevent accumulation, so that the sand can evenly fall on the screen, so that the screen can be fully utilized; there is a shaking unit, The sand screening box is shaken in the circumferential direction, which helps the movement of the sand on the screen and improves the screening efficiency.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a high-efficiency sand screening device for building construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] In construction, sand is a commonly used and indispensable raw material. In order to meet different construction needs, sand screening is required. The existing sand screening devices are easy to block...
