Abstract

The invention relates to the technical field of material crushing equipment, and particularly relates to a protective screen. The protective screen comprises a sieve frame and sieve bars, wherein the sieve bars are uniformly ranked in the sieve frame; an arched mesh enclosure is arranged above the sieve frame; the periphery of the mesh enclosure is provided with material collecting troughs. The protective screen has the characteristics that the arched mesh enclosure is arranged above the sieve frame, and the periphery of the mesh enclosure is provided with the material collecting troughs; when materials fall off, small granule materials pass through the sieve enclosure and fall off into the sieve frame, and the large granule materials are blocked by the sieve enclosure, roll into the material collecting troughs along the sieve enclosure, and are recycled and processed again, so that stoppage and sieve blocking are prevented effectively, and the material sieving quality and efficiency are improved greatly.

Description

Protection type screen cloth
Technical field
The present invention relates to equipment for pulverizing material technical field, especially a kind of protection type screen cloth.
Background technology
Existing crusher screen generally comprises the framework be made up of the side plate of a pair transverse direction and the connecting plate of a pair longitudinal direction, is connected with the grizzly bar of many longitudinal directions between biside plate.This structure comparison is stiff, and when the material of all size falls together, mix one, bulky grain is easily stuck on the net, stops granule, results in blockage, and increases burden and the wearing and tearing of screen cloth, reduction of service life, more impact sieve material efficiency and sieve material quality.
Summary of the invention
Easily blocking to overcome existing crusher screen, the deficiency of inefficiency, the invention provides a kind of protection type screen cloth.
The technical solution adopted for the present invention to solve the technical problems is: a kind of protection type screen cloth, comprises screen frame and grating, and grating is evenly arranged in screen frame, and the top of screen frame is provided with the guard of arch, and the surrounding of guard is provided with material collecting tank.
The invention has the beneficial effects as follows, the guard of arch is set above screen frame, and material collecting tank is set in the surrounding of guard, when material falls, small particles material falls into screen frame through guard, and large granular materials is stopped by guard, roll in material collecting tank along guard, be recovered reprocessing, effectively prevent blocking card net, substantially increase sieve material quality and sieve material efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. screen frames, 2. grating, 3. guard, 4. material collecting tank in figure.
Detailed description of the invention
If Fig. 1 is structural representation of the present invention, a kind of protection type screen cloth, comprises screen frame 1 and grating 2, and grating 2 is evenly arranged in screen frame 1, and the top of screen frame 1 is provided with the guard 3 of arch, and the surrounding of guard 3 is provided with material collecting tank 4.
The guard 3 of arch is set above screen frame 1, and material collecting tank 4 is set in the surrounding of guard 3, when material falls, small particles material falls into screen frame 1 through guard 3, large granular materials is stopped by guard 3, rolls in material collecting tank 4, be recovered reprocessing along guard 3, effectively prevent blocking card net, substantially increase sieve material quality and sieve material efficiency.
