Abstract
The utility model discloses a double-rack staggering structure of a pin roll. The double rack staggering structure comprises the pin roll (1), wherein connection holes (2) are formed in two ends of the pin roll (1); a plurality of grinding teeth are arranged on the outer surface of the pin roll (1); the grinding teeth distributed in the same circumference form a group; one group of grinding teeth is composed of arc teeth (6), lune teeth (7) and trapezoid teeth (5); one lune tooth (7) is arranged between every two adjacent arc teeth (6); one trapezoid tooth (5) is arranged between the adjacent arc tooth (6) and lune tooth (7). The pin roll double rack alternating structure has the benefits of high efficiency, good cutting property and good wearing resistance.
Description
Technical field
The utility model relates to the profile of tooth technology of cracker teeth roller, particularly a kind of discaling roll bidentate shape cross structure.
Background technology
Discaling roll is the critical piece of rod-toothed crusher, and in use, the crushing teeth of discaling roll not only will bear larger load, also needs to have higher wearability and smear metal.In prior art, discaling roll crushing teeth mostly is single profile of tooth, if when tooth-shape structure contacts for putting with material piece, can be fast that large material piece is broken, but while being broken into granule, efficiency is lower, if tooth-shape structure and material piece are line while contacting, breaking strength is relatively low, if tooth-shape structure and material piece are face while contacting, poor to the crushing effect of large material piece, efficiency is lower, but for the fragmentation of little material piece, efficiency is higher again.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the discaling roll bidentate shape that a kind of efficiency is high, smear metal good and wearability is good cross structure is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of discaling roll bidentate shape cross structure, it comprises discaling roll, the two ends of discaling roll all offer connecting hole, on discaling roll outer surface, be provided with many group crushing tooths, the crushing tooth being distributed on same circumference is one group, one group of crushing tooth is comprised of circle-arc tooth, arc tooth and stepped tooth, and is provided with an arc tooth between every adjacent two circle-arc teeth, is provided with a stepped tooth between adjacent circle-arc tooth and arc tooth.
The outer end of described connecting hole is provided with the ringfeder stepped hole that ringfeder is installed.
In described connecting hole horizontal direction, offer symmetrical key.
Described discaling roll inside is hollow structure.
Described many groups crushing tooth is in spiral distribution on the outer surface of discaling roll.
The utlity model has following advantage: discaling roll bidentate shape cross structure of the present utility model, circle-arc tooth is broken large material piece effectively, arc tooth can carry out fragmentation to little material piece efficiently, and stepped tooth can not only prevent that material piece is stuck between circle-arc tooth and arc tooth, and can carry out second-time breakage to material, again improve crushing efficiency, through the roller tooth of specially treated, tool has good wearability, so he has advantages of that efficiency is high, smear metal good and wearability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional schematic of the present utility model;
Fig. 3 is the utility model list group crushing teeth schematic diagram;
In figure, 1-discaling roll, 2-connecting hole, 3-ringfeder stepped hole, 4-symmetrical key, 5-stepped tooth, 6-circle-arc tooth, the arc tooth of 7-.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, Figure 2 and Figure 3, a kind of discaling roll bidentate shape cross structure, it comprises discaling roll 1, discaling roll 1 inside is hollow structure, the two ends of discaling roll 1 all offer connecting hole 2, on discaling roll 1 outer surface, be provided with many group crushing tooths, many group crushing tooths are in spiral distribution on its outer surface, the crushing tooth being distributed on same circumference is one group, one group of crushing tooth is comprised of circle-arc tooth 6, arc tooth 7 and stepped tooth 5, and between every adjacent two circle-arc teeth 6, be provided with an arc tooth 7, between adjacent circle-arc tooth 6 and arc tooth 7, be provided with a stepped tooth 5.The outer end of described connecting hole 2 is provided with the ringfeder stepped hole 3 that ringfeder is installed, and offers symmetrical key more than 4 group crushing tooths in spiral distribution on the outer surface of discaling roll 1 in connecting hole 2 horizontal directions.
The course of work of the present utility model is as follows: the rotation of motor drive shaft, main shaft drives discaling roll 1 rotation by symmetrical key and ringfeder syndeton, discaling roll 1 carries out fragmentation by rotation to material, in shattering process, circle-arc tooth 6 is that line contacts with material piece, impulsive force is larger, can to large material, carry out fragmentation fast, arc tooth 7 is that face contacts with material piece, can carry out large area fragmentation to small bulk body, improved crushing efficiency, and stepped tooth 5, can prevent that material piece is stuck between circle-arc tooth 6 and arc tooth 7, and can carry out second-time breakage to material, again improve crushing efficiency.
