Abstract
The utility model discloses a kind of roll coal crusher tooth plate fast assembling disassembling structures, it includes Cylindrical toothed plates, upper groove surface 5-8 ° of inclined upward of surface groove outward is respectively equipped at the dovetail groove both ends of each piece of Cylindrical toothed plates, there are one and the consistent special-shaped skewback in surface groove inclined-plane respectively on each surface groove, a stop nut is welded in the inner end of special-shaped skewback, it is provided with the through-hole for leading to the other end consistent with stop nut aperture along central axes on special-shaped skewback, one bolt is installed from outer end to stop nut hole one end in through-hole.The utility model has the advantages that firmly install, it is good to dismount quick, anti-loosening effect.
Description
Technical field
The utility model relates to mechanical organ, especially a kind of roll coal crusher tooth plate fast assembling disassembling structure.
Background technique
The roller of existing roll coal crusher is all that several piece arc tooth plate is circumferentially fixed with outside cylinder, by two when work
A roller do it is relatively uniform run at high speed, the material extruding that will enter between two rollers is pulverized.Because of the fixed form of tooth plate
Bolt fastening is mostly used, and exposure is directly contacted with material bolt outward, easily causes screw bolt abrasion, bolt is easily produced by material impact
It is raw to loosen, it will lead to tooth plate and loosen, influence using effect, increase maintenance capacity, and replacement tooth plate difficulty is big, the time is long.
Summary of the invention
The utility model aim purpose is to provide a kind of tooth plate and firmly installs, and is not easy to loosen, replacement tooth plate fast power-saving
Roll coal crusher tooth plate fast assembling disassembling structure.
The technical solution of the utility model is completed as follows, it includes Cylindrical toothed plates, it is characterised in that:
The dovetail groove both ends of each piece of Cylindrical toothed plates are respectively equipped with upper groove surface 5-8 ° of inclined upward of surface groove outward, on each inclined-plane
Have one and the consistent special-shaped skewback in surface groove inclined-plane above slot respectively, the inner end of special-shaped skewback be welded with one it is locking
Nut is provided with the through-hole for leading to the other end consistent with stop nut aperture along central axes on special-shaped skewback, in through-hole
One bolt is installed from outer end to stop nut hole one end.The bolt installed in through-hole from outer end to stop nut hole one end
It is a kind of hexagon-headed bolt.
The utility model has the advantages that firmly install, it is good to dismount quick, anti-loosening effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment is described in detail in conjunction with attached drawing, it includes Cylindrical toothed plates, at 1 both ends of dovetail groove of each piece of Cylindrical toothed plates point
Not She You upper groove surface 5-8 ° of inclined upward of surface groove 2 outward, have one and surface groove respectively on each surface groove
The consistent special-shaped skewback 3 in inclined-plane, is welded with a stop nut 4 in the inner end of special-shaped skewback, on special-shaped skewback in
Axis is provided with the through-hole 5 for leading to the other end consistent with stop nut aperture, from outer end to stop nut hole one in through-hole
End is equipped with a hexagon-headed bolt 6.
The first insertion among two substrates of roller by tooth plate when installation, then the surface groove of tooth plate one end is pulled out, it will be different
Type skewback is shifted tooth plate among two substrates onto after being packed into surface groove, then in the other end that tooth plate pull-out is oblique special-shaped skewback loading
Face slot pushes out nut by skewback by locking hex bolts, and the contact of incline plane on the inclined-plane and tooth plate that make skewback is increasingly
Tightly, achieve the purpose that fasten tooth plate after both ends fit closely respectively.This fast assembling disassembling structure not only can guarantee equipment operation
Stability and safety, and difficulty and the time of tooth plate dismounting are greatly reduced, it improves work efficiency.
