The upper box body is fixedly arranged at the top of the lower box body through box body bolts.

And a discharging hopper is arranged in the lower box body and below the screen.

The scraping plate is detachably arranged on the rotor through a locking bolt.

The screen is fixed in the mounting groove at the top of the lower box body through the screen connecting seat and the fixing bolt.

The washboard structure comprises a washboard mounting plate, the washboard mounting plate is fixed on the inner side wall of the upper box body, a washboard is fixedly mounted on the inner side wall of the washboard mounting plate through a bolt assembly, and a protrusion is arranged on the outer side wall of the washboard.

The utility model discloses there is following beneficial effect:

1. through adopting the breaker of above-mentioned structure, can be used for the breakage of material, in the crushing process, through main shaft drive rotor, through rotor drive tup, contact with the material through tup, and then realize the breakage of material, after broken, can scrape the material that is located the bottom through scraping the flitch to throw to the washboard structure, and then carry out the breakage to the material through washboard structure and tup combined action.

2. The bottom material is fully stirred through the scraping plate, the material blocking the hole is thrown into a crushing area, and the crushing efficiency is improved.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: the feeding device comprises a feeding hole 1, a nut 2, a fixing bolt 3, a screen connecting seat 4, a rotor 5, a lower box body 6, a lower hopper 7, a screen 8, a hammer 9, a scraping plate 10, a box body bolt 11, a bulge 12, a bolt assembly 13, a washboard mounting plate 14, a washboard 15, a main shaft 16, an upper box body 17 and a locking bolt 18.

Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1, the scraper crusher comprises a lower box body 6, an upper box body 17 is installed at the top of the lower box body 6, a main shaft 16 is installed between the lower box body 6 and the upper box body 17, a rotor 5 is installed on the main shaft 16, hammers 9 are uniformly hinged on the rotor 5, a scraper plate 10 is fixedly installed on the rotor 5 between adjacent hammers 9, a screen 8 is installed inside the lower box body 6 and below the rotor 5, and a washboard structure is arranged on the inner side wall of the top of the upper box body 17; and a feeding hole 1 is formed in the side edge of the top of the upper box body 17. Through adopting the breaker of above-mentioned structure, can be used for the breakage of material, in the crushing process, through 16 drive rotors 5 of main shaft moreover, through rotor 5 drive tup 9, contact with the material through tup 9, and then realize the breakage of material, after the breakage, can scrape the material that is located the bottom through scraping flitch 10 to throw to the washboard structure, and then carry out the breakage through washboard structure and tup 9 combined action to the material.
