Description

Sand and stone separating screen

Technical Field

The utility model relates to a construction field specifically is grit separating screen.

Background

Grading, particle size distribution and the like are main performance indexes of sand and stones and play an important role in the performance of the prepared concrete, the grading of the sand and the stones directly influences the strength, impermeability, workability, durability and economy of the concrete, wherein the particle shape of the stones is better in a shape close to a spherical shape or a cubic shape, the needle-shaped particles are poorer in shape, the needle-shaped particles are required to be screened to remove the needle-shaped stones, the construction sand and the stones are usually required to be filtered by a mesh screen on a construction site, the coarse particles are removed, and the finer sand or the stones with the used particle sizes are left.

In the prior art, the design of the existing mesh screens for filtering sand in construction sites is simple, the mesh screens are required to be fixed at high positions when in use, then the sand is shoveled onto the mesh screens at the high positions through manpower or mechanical force, the operation is very laborious, the mesh screens arranged at the high positions are troublesome to shake, the screening efficiency is low, sand soil and gravel often cannot be screened out completely and effectively when leaking from the mesh screens, so that part of gravel to be screened is remained on the surfaces of the mesh screens in the screening process, the part of gravel is easy to form accumulation on the mesh screens, the gravel accumulated on the mesh screens can influence the subsequent gravel screening, and the process of the gravel sorting is a big obstacle, so that the subsequent gravel sorting process can not be influenced when the mesh screens are used for the gravel sorting, and the screening efficiency can be improved, the method becomes a problem to be solved urgently in the field of building construction.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome prior art because form when screening the grit and pile up and cause the not enough of follow-up screening effect to reduce step by step on the screen cloth, provide a grit sorting sieve, through the clearance of piling up the grit on screen cloth surface, the whole efficiency of effectual improvement grit screening.

The purpose of the utility model is mainly realized through the following technical scheme:

the sand and stone separating screen comprises a supporting cross bar, a plurality of idler wheels capable of keeping the supporting cross bar balanced are arranged below the supporting cross bar, one end of the supporting cross bar is free, a bearing rod vertical to the supporting cross bar is arranged at the other end of the supporting cross bar, the lower end of the pressure-bearing rod is fixedly connected with the support cross rod, the pressure-bearing rod extends upwards perpendicular to the support cross rod and the upper end is free, an inclined screen is arranged between the pressure bearing rod and the support cross rod, the upper end of the screen is fixed with the upper end of the pressure bearing rod, the lower end of the screen is fixed with the free end of the support cross rod, the top of screen cloth is equipped with the slide bar parallel with the screen cloth, and the upper end of slide bar is fixed with the upper end of bearing pole, and the lower extreme of slide bar is fixed with the free end of supporting the horizontal pole, and the cover is equipped with the clear heap subassembly that can freely slide along the slide bar on the slide bar, clear heap subassembly and the wire side contact of screen cloth.

When sand and stone are sorted in the prior art, a flat screen with a space reserved below is usually adopted for screening, when the screening is carried out in the mode, the sand and stone are usually conveyed to a high place, then the sand and stone are poured on the screen, the sand and stone on the screen are cleaned after the separation is finished, and then the next batch of screening is carried out, so that the efficiency of screening the sand and stone is low, and the sand and stone can be screened only by conveying the sand and stone to the high place through manpower or machinery when the sand and stone are screened, a large amount of labor force is consumed, or more large-scale equipment is required to be configured, so that the screening of the sand and stone can be finished, and the efficiency in the screening process of the sand and stone can be greatly influenced; the utility model discloses in, the screen cloth that sets up through the slope replaces the screen cloth of keeping flat, and the effectual process of transporting the grit to the eminence omits to through supporting the horizontal pole, the triangular structure between screen cloth and the pressure-bearing rod forms stable support, makes the screen cloth can more effectual resistance to the impact of grit, because the screen cloth of slope forms the piling up of grit in the latter half of screen cloth easily, so the utility model discloses in clear away accumulational grit through the mode that sets up the slide bar and establish the clear subassembly of piling up at the slide bar upper cover, can effectually keep the screening function on screen cloth surface not by the realization of influence, through the combined action of the screen cloth of placing and clear heap subassembly of slope, the effectual clearance of having accomplished the grit on screen cloth surface to the whole efficiency of effectual improvement grit screening.
