Abstract
The utility model discloses a combined crushing device for a coal crusher. The combined crushing device for the coal crusher comprises a mounting substrate, wherein a rotatable crushing roller is arranged in the middle of the mounting substrate; a roller shaft is arranged in the center of the crushing roller; fixed cover plates are respectively arranged above and below the crushing roller; the roller shaft penetrates through the fixed cover plates. According to the combined crushing device for the coal crusher, by utilizing the fixed cover plates at two ends of the crushing roller, when roller teeth of the crushing roller are damaged, a user only needs to replace the crushing roller, a whole crushing roll is not required to be replaced, so that the using cost is reduced. In addition, because the fixed cover plates are fixed through double holes, torque of the crushing roller can be improved, and the crushing efficiency is improved.
Description
Technical Field
The utility model relates to a coal mining equipment, more exactly, be a combination formula breaker for coal breaker.
Background
The coal crusher is also called a double-stage crusher, belongs to high-efficiency fine crushing equipment, mainly aims at the problem of crushing coal, refines the coal into coal particles or coal powder according to actual requirements, and then transmits the coal powder to a storage bin by using an air duct. The crushing roller of the existing coal crusher is integrally installed, and once the roller teeth are damaged, the whole crushing roller needs to be replaced, so that the cost is high. In addition, the existing crushing roller is driven by a central shaft, so that the torque is difficult to improve.
Disclosure of Invention
The utility model discloses solve the technical problem that prior art exists to a combination formula breaker for coal breaker is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a combination formula breaker for coal breaker, a combination formula breaker for coal breaker contain a mounting substrate, mounting substrate's middle part be equipped with a rotatable broken roller, broken roller's central authorities be equipped with a roller, broken roller's top and below be equipped with a fixed apron respectively, the roller run through fixed apron.
As the embodiment of the utility model provides a preferred, the middle part of fixed apron be equipped with a roller through-hole, the both sides of roller through-hole be equipped with a first fixing hole respectively, the central authorities of broken roller be equipped with a main through-hole, the both sides of main through-hole be equipped with a second fixing hole respectively, clamping screw runs through respectively first fixing hole and second fixing hole and with broken roller fixed connection.
The utility model discloses a combination formula breaker for coal breaker utilizes the fixed apron at broken roller both ends, and the roller tooth that takes place to take place to damage as broken roller, the user only need change broken roller can, and need not change whole crushing roller, reduced use cost. In addition, because fixed apron adopts the diplopore fixed, the moment of torsion of broken roller can further obtain promoting, improves crushing efficiency.
