Problems solved by technology

In small construction sites, the sand screening operation is generally carried out manually, the screen is placed on the ground obliquely, and then the sand is scooped up and thrown onto the screen surface by manually using tools such as shovels. This kind of sand screening operation is costly. Large manpower, and the sand screening effect is not stable enough, which affects the sand screening effect

Embodiment 1

[0025] see Figure 1-2 , a sand screening device for building construction, including a sand throwing mechanism and a sand screening assembly, the sand throwing mechanism includes a bottom plate 1, a sand discharge tank 2, a sand throwing assembly and a sand storage tank 9, and the sand discharge tank 2 passes through the first A support frame 3 is fixedly installed on the bottom plate 1, and a sand throwing assembly is arranged above the sand removal tank 2. The sand throwing assembly includes a turntable 4, a second support frame 5 and a sand throwing shovel 7. The second support frame 5 is vertically installed on the upper end face of the bottom plate 1 and symmetrically distributed on both sides of the sand removal tank 2. The upper end of the second support frame 5 is rotatably installed with a turntable 4, and the turntable 4 is located directly above the sand removal tank 2. The turntable 4 A number of connecting frames 6 are evenly distributed in the last week, and the...

Embodiment 2

[0034] see image 3 , In construction, there are many types of sand used, so it is necessary to screen sand with different sizes of particles. The mesh size of the screen 18 needs to match the requirements of the screen sand. For replacement, this embodiment is further improved on the basis of Embodiment 1. The improvement is: a socket is provided on one side of the mounting frame 15, and a screen frame 17 is arranged in the movable card in the socket. The screen 18 is fixedly installed on the screen frame 17; when the screen 18 needs to be replaced, the screen frame 17 of the original screen 18 is pulled out from the socket of the installation frame 15, and then the screen frame with the designated mesh screen 18 is removed. 17 is inserted into the mounting frame 15, which is convenient for quick disassembly and assembly;

[0035] In order to facilitate pulling out the screen frame 17 from the mounting frame 15, a handle 19 is provided on the screen frame 17, and the screen ...

Abstract

The invention discloses a sand screening device for building construction. The sand screening device comprises a sand throwing mechanism and a sand screening assembly, wherein the sand throwing mechanism comprises a bottom plate, a sand discharging groove, a sand throwing assembly and a sand storage tank; the sand discharging groove is fixedly installed on the bottom plate through a first supporting frame; the sand throwing assembly is arranged above the sand discharging groove; the sand storage tank is arranged above one end of the sand discharging groove; a sand discharging opening is formedbelow the sand storage tank; a valve is mounted on the sand discharging opening; and the sand screening assembly is located at the end, away from the sand storage tank, of the sand discharging groove. According to the sand screening device for building construction, a continuously rotating sand throwing shovel is used for continuously throwing sand in the sand discharging groove to the surface ofa screen, so that large-particle impurities in the sand are screened out, the screening efficiency is high, manpower is saved, and meanwhile the sand screening effect is stable and reliable; the sandis continuously supplied into the sand discharging groove through the sand storage tank, manual intervention is not needed, the supply speed is adjustable, and thus flexibility and convenience are achieved; and the inclination angle of the screen can be adjusted, so that the sand screening device can adapt to different sand screening operation requirements, and the sand screening effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a sand screening device for building construction. Background technique [0002] In the process of building construction, sand is one of the most commonly used building materials. In actual use, due to the technical requirements of building construction, sand needs to be screened to remove large particles of impurities in the sand. In small construction sites, the sand screening operation is generally carried out manually, the screen is placed on the ground at an incline, and then the sand is shoveled up and thrown onto the screen surface by manually using tools such as shovels. Large manpower, and the sand screening effect is not stable enough, thus affecting the sand screening effect. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a sand screening device for building construction to solve the problems raised in the above ba...
