Abstract
The utility model relates to a screen stencil for a crusher. The screen stencil of the crusher has at least 6 grizzly bars arranged horizontally. At least six grooves are arranged on the horizontal grizzly bars to form the groove grizzly bars. At least 6 longitudinal grizzly bars are embedded and fixed in the grooves of the groove grizzly bars. The area of the downward surface of the groove grizzly bars is smaller than the area of a main visual surface. When being attacked by the solid material, the groove grizzly bars and the longitudinal grizzly bars are not easy to be moved. When the area of the downward surface of the groove grizzly bars is smaller than the area of the main visual surface, the mesh number of the screen stencil within the unit area can be increased effectively and the sieving rate of the screen stencil for solid material is improved.
Description
Technical field
The utility model relates to a kind of equipment of broken solid material, more particularly, relates to the screen cloth that uses on a kind of disintegrating machine.
Background technology
Screen cloth on the disintegrating machine in use is easy to wearing and tearing, the especially easier wearing and tearing of the screen cloth that uses on the heavy-duty crusher.Be used for the disintegrating machine of hard solid materials such as broken coal cinder, stone, the wear-resisting of screen cloth had relatively high expectations, most of screen cloth is formed by round steel or braided steel wire, and generally, the screen cloth of round steel or braided steel wire divides plain weave mesh screen and ripple mesh screen.The similar WARP-KNITTING of structure of tradition screen cloth, easy deformation or the breakage under the bump of solid material, extruding of the screen cloth of braiding structure.In order to address this problem, existing screen cloth often uses thicker round steel of diameter or braided steel wire.Because the effective area of screen cloth mesh is limited by round steel or steel wire diameter, round steel or gauge of wire are crossed the operating efficiency that conference reduces screen cloth, and mesh and the big problem of scarfing cinder difficulty also take place to stop up easily.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of screen cloth of disintegrating machine, and it improves screen strength by the mesh structure that changes.
The purpose of this utility model is achieved in that a kind of screen cloth of disintegrating machine, have 6 transversely arranged grizzly bars at least, 6 grooves are set on the transversely arranged grizzly bar at least and constitute band groove grizzly bar, have at least 6 vertical grizzly bars to embed and be fixed in the groove of band groove grizzly bar, the face of the overlooking area of band groove grizzly bar is less than the main-vision surface area.
On the basis of technique scheme, the utility model also has following further scheme:
Described vertical grill width equals the depth of groove with the groove grizzly bar.
At least be provided with 6 grooves on described vertical grizzly bar.
Be with groove grizzly bar and vertical grizzly bar two ends that extending part is arranged, band groove grizzly bar and vertical grizzly bar embed in the embeded slot of rack by extending part respectively, and the embeded slot of rack has the grizzly bar fixed mechanism.
Described grizzly bar fixed mechanism is for having strong market potential, and vertically the grizzly bar two ends are provided with pin-and-hole, and rack is provided with through hole.
The cross section of described vertical grizzly bar or band groove grizzly bar is trapezoidal.
Described vertical grizzly bar is made by macromolecular material, and band groove grizzly bar is made by metal material.
Described vertical grizzly bar is made by metal material, and band groove grizzly bar is made by macromolecular material.
Advantage of the present utility model is as follows:
Because, 10 grooves are set on the transversely arranged grizzly bar at least and constitute band groove grizzly bar, have at least 10 vertical grizzly bars to embed and be fixed in the groove of band groove grizzly bar, the face of the overlooking area of band groove grizzly bar is less than the main-vision surface area.So band groove grizzly bar and vertical grizzly bar are difficult for displacement when being impacted by solid material; The face of the overlooking area of band groove grizzly bar can effectively increase the mesh quantity in the screen cloth unit are during less than the main-vision surface area, can improve the sieving rate of screen cloth to solid material.
