Abstract
The invention discloses a grid plate for a crusher. A grid gap array is arranged on the grid plate, and grid gaps are a vertical rectangular grid gaps and the widths of the grid gaps are gradually increased from the front side to the back side. The grid plate is a rectangular plate which is bended and arched, and the grid plate is arched to the back side. After the grid plate disclosed by the invention is used, the original slantwise grid gaps are changed into the vertical grid gaps, the grid gaps are narrow in the front side and wide in the back side, and a material is transported from the front side of the grid plate to the back side of the grid plate. The production practice test shows that the discharged material is even in granularity and smooth to discharge, the blockage of the grid gaps can be avoided, the cast iron-cast grid plate is good in rigidity without deformation nearly, and according to the unique design of grid sections, the yield can be guaranteed, and the material blockage can be further avoided.
Description
Technical field
The present invention relates to the disintegrating machine grate plate.
Background technology
The PPC1609 single block hammer crusher is the efficient lime stone disintegrating apparatus of new generation that China introduces, what utilize is that single rotor beats building stones to counterpunch board collision principle, the characteristics ratio of reduction is big, can fragmentation＜500mm ore, primary fragmentation is to going into the abrasive material degree, simple to operate, easy to maintenance, improved working strength of workers.
The discharging double-edged fine-toothed comb of one of critical component of PPC1609 single block hammer crusher, existing technical scheme are with the tup direction of motion certain angle to be arranged, and form oblique comb seam, and whole device has 16 little grate plates.Find in the production practices, though guaranteed discharging-material size, stop up easily.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of disintegrating machine grate plate, and the seam of avoiding when guaranteeing discharging-material size combing stops up.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of disintegrating machine grate plate, this grate plate is provided with the comb slot array, it is characterized in that: described comb seam is broadened to the back side by the grate plate front gradually for the width of vertical rectangle comb seam and the seam of combing.
Preferably, described grate plate is arc rectangular slab for crooked, and described grate plate arches upward to rear side.
Preferably, described comb slot array is 8 * 2 array, and the comb seam length of the left and right sides was combed less than the middle part and stitched length during every row combed and stitches.
Preferably, described grate plate sews on down at the comb comb of the seam left and right sides of every row that both sides are provided with a step-like installing hole.
Preferably, described grate plate is ironcasting.
The present invention changes oblique comb seam original on the grate plate into vertical comb seam, and the positive narrow back side of seam of combing is wide, material is just carried towards the grate plate back side by grate plate, check through production practices, discharging-material size is even, unobstructed, the obstruction of the seam of can avoiding combing, and the grate plate good rigidly of cast iron casting, the generation of putty has been avoided in almost not distortion again when unique grid section design has guaranteed output.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is the grate plate structural representation;
Fig. 2 is A-A cutaway view among Fig. 1;
Fig. 3 is B-B cutaway view among Fig. 1;
Fig. 4 is C-C cutaway view among Fig. 1.
The specific embodiment
Fig. 1 to Fig. 4 shows the concrete structure of disintegrating machine grate plate, and this grate plate 1 is provided with seam 10 arrays of combing, and described comb seam 10 is broadened to the back side by the grate plate front gradually for the width of vertical rectangle comb seam and the seam of combing.Described grate plate is arc rectangular slab for crooked, and described grate plate is to rear side arch upward (by two side direction middle part up and down arching upward).Described comb slot array is 8 * 2 array, and the comb seam length of the left and right sides was combed less than the middle part and stitched length during every row combed and stitches.Described grate plate sews on down at the comb comb of the seam left and right sides of every row that both sides are provided with a step-like installing hole 11.Described grate plate is ironcasting.
Just towards the conveying of the grate plate back side, owing to the seam 10 of combing is that vertical rectangle comb stitches and the width of the seam of combing is broadened to the back side gradually by the grate plate front, such structure has guaranteed that discharging-material size is even, unobstructed to material, can avoid the obstruction of combing and stitching by grate plate.
