Abstract
The utility model discloses a hammer shaft pressure plate bolt protection device of a crusher, comprising a hammer shaft pressure plate fixedly arranged on a hammer shaft rotor disk; a plurality of connecting bolts are evenly and annularly distributed between the hammer shaft pressure plate and the hammer shaft rotor disk; the hammer shaft rotor disk or the hammer shaft pressure plate is provided with lugs which encircle the head parts of all connecting bolts; the height of the lugs is more than or equal to that of the head parts of the connecting bolts, so that the materials can hardly enter the space between the hammer shaft rotor disk and the inner wall of the crusher shell body so as to well protect the connecting bolts on the hammer shaft pressure plate; therefore, the connecting bolts are not easy to wear and the service life is prolonged; besides, the hammer shaft pressure plate is not easy to fall off, so as to reduce the using cost of the crusher and facilitate the maintenance.
Description
Technical field
The utility model relates to the bolt protective device that a kind of disintegrating machine is used.
Background technology
Disintegrating machine in use, disintegrating machine two ends rotor disk hammer shaft pressuring plate set bolt is easy to wear, causes the hammer shaft pressuring plate to come off, influence the normal operation of disintegrating machine, because of the set bolt serious wear, the short time is difficult to take out in rotor disk, causes disintegrating machine long downtime when making maintenance; Simultaneously, disintegrating machine is when operation, less material be easy to enter two ends rotor disk and housing between the space in, cause hammer shaft pressuring plate set bolt and material that extruding and friction take place, thereby increased the use cost of attendant's labour intensity and machine, reduced the operating efficiency of disintegrating machine.
The utility model content
Technical problem to be solved in the utility model provides a kind of crusher hammer shaft pressuring plate bolt protective device; to solve disintegrating machine in using engineering; two ends rotor disks hammer shaft pressuring plate is easily frayed because of set bolt, causes the hammer shaft pressuring plate to come off and problem such as maintenance difficult.
For solving the problems of the technologies described above; the technical solution of the utility model is: crusher hammer shaft pressuring plate bolt protective device; comprise the hammer shaft pressuring plate that is fixedly mounted on the hammer axle rotor disk; annular is evenly equipped with some connecting bolts between described hammer shaft pressuring plate and the described hammer axle rotor disk; described hammer axle rotor disk or hammer shaft pressuring plate are provided with the projection around whole connecting bolt heads, and the height of described projection is more than or equal to the height of connecting bolt head.
As a kind of improvement, described projection is the annulus that is fixed on the described hammer axle rotor disk.
As a kind of further improvement, described projection is the annulus that is fixed on the described hammer shaft pressuring plate.
As a kind of further improvement, be fixed with some material toggling sheets that the material that enters between described hammer axle rotor disk and the crusher shell inwall can be thrown away on the described hammer shaft pressuring plate outer face.
Owing to adopted technique scheme; crusher hammer shaft pressuring plate bolt protective device; comprise the hammer shaft pressuring plate that is fixedly mounted on the hammer axle rotor disk; annular is evenly equipped with some connecting bolts between described hammer shaft pressuring plate and the described hammer axle rotor disk; described hammer axle rotor disk or hammer shaft pressuring plate are provided with the projection around whole connecting bolt heads; the height of described projection is more than or equal to the height of connecting bolt head; make material be difficult to enter between described hammer axle rotor disk and the crusher shell inwall; connecting bolt on the described hammer shaft pressuring plate has been carried out good protection; make it be difficult for being worn; prolonged the service life of connecting bolt; described hammer shaft pressuring plate can not come off easily; reduced the use cost of disintegrating machine, and also provide very big convenience for keeping in repair.

The specific embodiment
As Fig. 1; Fig. 2 and shown in Figure 3; crusher hammer shaft pressuring plate bolt protective device; comprise the hammer shaft pressuring plate 2 that is fixedly mounted on the hammer axle rotor disk 1; annular is evenly equipped with some connecting bolts 3 between described hammer shaft pressuring plate 2 and the described hammer axle rotor disk 1; described hammer axle rotor disk 1 or hammer shaft pressuring plate 2 are provided with the projection 4 around whole connecting bolt 3 heads; described protruding 4 height is more than or equal to the height of connecting bolt 3 heads; described protruding 4 can be for being fixed on the annulus on the described hammer axle rotor disk 1; also can be for being fixed on the annulus on the described hammer shaft pressuring plate 2; its protruding height is as the criterion with the head of connecting bolt 3; at its surface wear resistance electrode coating; prevent that material from entering between described hammer axle rotor disk 1 and the crusher shell inwall; connecting bolt on the described hammer shaft pressuring plate 23 is worn and torn to cause its damage; prolonged the service life of described connecting bolt, and made described hammer shaft pressuring plate 2 difficult drop-offs and for convenience detach.
Be fixed with some material toggling sheets 5 that the material that enters between described hammer axle rotor disk 1 and broken casing such as Fig. 4 and Fig. 5 body inwall can be thrown away on described hammer shaft pressuring plate 2 outer faces; promptly on the hammer shaft pressuring plate, weld the iron block of some according to certain angle; play protective effect, also can make hammer shaft pressuring plate 1 produce the effect of stirring blanking simultaneously described bolt.
