Abstract

The utility model relates to a screen stencil used on a crusher, which is formed by at least six transverse grizzly bars which are transversely arrayed. At least six grooves and six lug bosses are arranged on the transverse grizzly bars; at least six longitudinal grizzly bars are arrayed along the longitudinal direction and are intersected with the transverse grizzly bars. The longitudinal grizzly bars are embedded in the grooves of the transverse grizzly bars, and jointing points are arranged between the transverse grizzly bars and the longitudinal grizzly bars. The screen stencil provided by the utility model not only can improve the service life of the screen stencil, but also is propitious to increase the mesh amount in a unit area of the screen stencil.

Description

A kind of screen cloth

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.The similar WARP-KNITTING of structure of tradition screen cloth, screen cloth easy deformation or breakage under the bump of solid material, extruding.In order to address this problem, existing screen cloth often uses the bigger round steel braiding of diameter.Because the effective area of screen cloth mesh is subjected to the round steel diameter restrictions, the round steel diameter is crossed the operating efficiency that conference reduces screen cloth, and mesh and the big problem of scarfing cinder difficulty 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, and it improves the intensity of screen cloth by the shape of cross section of improvement grizzly bar.

The purpose of this utility model is achieved in that a kind of screen cloth, and at least 6 horizontal grizzly bars are transversely arranged, and laterally the cross section of grizzly bar is a rectangle or trapezoidal, laterally has 6 grooves and 6 boss at least on the grizzly bar; Have the vertical arrangement of 6 vertical grizzly bars and crossing with horizontal grizzly bar at least, vertically grizzly bar embeds in the groove of horizontal grizzly bar, laterally between grizzly bar and the vertical grizzly bar pad is arranged.

On the basis of technique scheme, the utility model also has following further scheme:

Have 6 grooves and 6 boss on described vertical grizzly bar at least.

Described vertical grizzly bar is the vertical bar shape.

Advantage of the present utility model is as follows:

Because laterally the cross section of grizzly bar is a rectangle or trapezoidal, laterally have 6 grooves and 6 boss at least on the grizzly bar; Have the vertical arrangement of 6 vertical grizzly bars and crossing with horizontal grizzly bar at least, vertically grizzly bar embeds in the groove of horizontal grizzly bar, laterally between grizzly bar and the vertical grizzly bar pad is arranged; Vertically grizzly bar embeds in the groove of horizontal grizzly bar and helps the location, thereby makes being connected of horizontal grizzly bar and vertical grizzly bar more reliable.Use cross section to be rectangle or trapezoidal horizontal grizzly bar, but the flour milling that helps to increase horizontal grizzly bar amass.The utility model not only can improve the service life of screen cloth, and helps increasing the mesh quantity in the screen cloth unit are.

The specific embodiment

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:

Referring to Fig. 1.At least 6 horizontal grizzly bars 2 are transversely arranged, use 9 horizontal grizzly bars 2 transversely arranged.Referring to Fig. 5 and Fig. 6.Laterally the cross section of grizzly bar 2 can be made rectangular surfaces 500 or trapezoidal faces 600, and promptly laterally the cross section of grizzly bar 2 is a rectangle or trapezoidal.In conjunction with Fig. 1, referring to Fig. 3.Laterally grizzly bar 2 has 9 grooves 300 and 9 boss 301.Laterally groove 300 and the boss 301 on the grizzly bar 2 can be realized by Sheet Metal Forming Technology.9 vertical grizzly bars are vertically arranged and are intersected with horizontal grizzly bar 2, and vertically grizzly bar 1 embeds in the groove 300 of horizontal grizzly bar 2.Described vertical grizzly bar has following two kinds of structures:

Referring to Fig. 1 and Fig. 3.Vertically the structure of grizzly bar vertically has 9 grooves 300 and 9 boss 301 on the grizzly bar with laterally grizzly bar 2 is identical.When vertically the grizzly bar structure was identical with horizontal grizzly bar 2 structures, vertically grizzly bar was referred to as the vertical grizzly bar 1 with groove.

Referring to Fig. 2 and Fig. 4.When the structure of vertical grizzly bar was the vertical bar shape, vertically grizzly bar can use band steel 200, and promptly described vertical grizzly bar is the vertical bar shape.Vertical bar shaped band steel 200 is a rectangle, and vertical bar shaped band steel 200 comprises square steel.When vertically grizzly bar uses vertical bar shaped band steel 200, can simplify the manufacturing process of vertical grizzly bar.

Referring to Fig. 1 and Fig. 2.9 vertical grizzly bars are vertically arranged and are intersected with horizontal grizzly bar 2, and vertically grizzly bar 1 embeds in the groove 300 of horizontal grizzly bar 2.Laterally grizzly bar 2 and vertically grizzly bar use iron and steel manufacturing.Use electric welding equipment laterally forming pad between grizzly bar 2 and the vertical grizzly bar, promptly laterally between grizzly bar 2 and the vertical grizzly bar pad is arranged.Pad is used for fixing being connected of horizontal grizzly bar 2 and vertical grizzly bar.Laterally the groove 300 of grizzly bar 2 can be made dovetail groove, and pad can form in the groove 300 of horizontal grizzly bar 2.The quantity of pad can be set as required.Described pad can be by spot welding or built-up welding, or welding manner such as butt-joint forms.

Claims (3)

1, a kind of screen cloth is characterized in that, at least 6 horizontal grizzly bars (2) are transversely arranged, and laterally the cross section of grizzly bar (2) is a rectangle or trapezoidal, laterally has 6 grooves and 6 boss at least on the grizzly bar (2); Have the vertical arrangement of 6 vertical grizzly bars and crossing with horizontal grizzly bar (2) at least, vertically grizzly bar embeds in the groove of horizontal grizzly bar (2), laterally between grizzly bar (2) and the vertical grizzly bar pad is arranged.

2, a kind of screen cloth according to claim 1 is characterized in that, has 6 grooves and 6 boss on described vertical grizzly bar at least.
