Abstract
The utility model discloses a kind of toothing of double teeth roller screening crusher, each crushing teeth on each roller of this disintegrating machine is by axially being arranged in order, the adjacent crushing teeth alternate 15 ° of layouts that stagger that make progress in the same footpath of main shaft.The utility model is applicable to the bulk materials of broken material size≤1200mm, discharging-material size≤300mm.
Description
Technical field
The utility model relates to a kind of toothing of double teeth roller screening crusher, relates in particular to the layout of crushing teeth on the disintegrating machine roller.
Background technology
Chinese patent CN87103574A is in disclosed a kind of ore crusher on December 2nd, 1987, contain a pair of rotatable cylinder, radially-protruding broken teeth are arranged on each cylinder, broken teeth be arranged to by axially spaced-apart, along the teeth that separate circumferentially bunch, teeth on teeth on cylinder bunch and another cylinder bunch are axially staggered, make the teeth of the teeth bunch on the cylinder, on the another one cylinder, pass through in the middle of the teeth of adjacent teeth bunch with it.The layout of its teeth on cylinder as shown in Figure 1.
The crushing teeth of above-mentioned double teeth roller screening crusher is a parallel arrangement, and it is by relative broken teeth cooperation interlock on two cylinders, the charging of broken fritter preferably; But bulk materials can't enter the occlusal area of broken teeth relative on two cylinders, and can't obtain fragmentation.
The utility model content
The technical problems to be solved in the utility model provides the toothing of the double teeth roller screening crusher of the broken bulk materials of a kind of energy interlock.
For solving the problems of the technologies described above, the toothing of a kind of double teeth roller screening crusher that the utility model proposes, its innovative point be each crushing teeth on each roller of this disintegrating machine by axially being arranged in order, the adjacent crushing teeth alternate 15 ° of layouts that stagger that make progress in the same footpath of main shaft.Two rollers form " eight " font layout.
Crushing teeth is a double teeth roller screening crusher main working parts, also is main easily worn part, and according to the classification of broken material, production capacity and pan feeding, discharging-material size are different, and then parameters such as the shape of tooth, fastening means, tooth depth all require difference.As the utility model optimal technical scheme, above-mentioned crushing teeth of the present utility model preferably adopts the broken awl of band crown shape crushing teeth.
The utility model is because the adjacent crushing teeth alternate 15 ° of layouts that stagger that make progress in the same footpath of main shaft, and two rollers form " eight " font layouts, and the crushing teeth on roller axially interlocks with the crushing teeth on another roller, forms very big interlock space.A crushing teeth on roller on the another one roller, pass through in the middle of the adjacent crushing teeth with it, can be applicable to the bulk materials of broken material size≤1200mm, discharging-material size≤300mm to bulk materials interlock fragmentation.
Description of drawings
Fig. 1 is the toothing schematic layout pattern of double teeth roller screening crusher in the prior art.
Fig. 2 is structural representation of the present utility model (single roller 8 dish crushing teeths);
Fig. 3-1 and Fig. 3 the-the 2nd, and (%d represents each crushing teeth of the utility model among the figure: degree) at the layout exploded view of roller.
Fig. 4 is the structural representation (analysing and observe) of the crushing teeth of the utility model.
Wherein, 1 is main shaft; 2 is crushing teeth; 3 is broken awl.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shown in Fig. 2, Fig. 3-1 and Fig. 3-2, the toothing of a kind of double teeth roller screening crusher that the utility model one preferred embodiment proposes, single roller 8 dish crushing teeths, the crushing teeth 2 of the broken awl of each band 3 crown shapes on each roller of this disintegrating machine axially is arranged in order by main shaft 1, the adjacent crushing teeth 2 alternate 15 ° of layouts that stagger that make progress in the same footpath of main shaft 1.
Below in conjunction with description of drawings course of action of the present utility model.
As shown in Figure 2, the crushing teeth 2 of the broken awl of the band 3 crown shapes on the crushing teeth 2 of the broken awl of the band on roller 3 crown shapes and another roller is axially staggered.Because adjacent crushing teeth 2 upwards is alternate 15 ° of layouts that stagger in the same footpath of main shaft 1, forms very big interlock space.The crushing teeth 2 of on a roller one the broken awl of band 3 crown shape on the another one roller, pass through in the middle of the crushing teeth 2 of the adjacent broken awl of band 3 crown shapes with it, can be to bulk materials interlock fragmentation.
Claims (2)
1, a kind of toothing of double teeth roller screening crusher is characterized in that each crushing teeth on each roller of this disintegrating machine by axially being arranged in order, the adjacent crushing teeth alternate 15 ° of layouts that stagger that make progress in the same footpath of main shaft.
2,, it is characterized in that above-mentioned crushing teeth is the broken awl of band crown shape crushing teeth according to the toothing of the described double teeth roller screening crusher of claim 1.
