Abstract
The utility model relates to the structural improvement of coal crushers, which comprises a machine body, and a rotor is arranged on the side of the coal crushing plate of the machine body. The utility model is characterized in that fan-shaped hammers are arranged on the double connecting rods of the rocking arm of the rotor, steps are arranged on the coal crushing plate, and a rolling screen composed of impellers is arranged in the machine body on the bottoms of the rotor and the coal crushing plate. The utility model has the characteristics of high productive efficiency, favorable coal conveying effect, etc.
Description
The utility model relates to the improvement of coal breaker structure.
The coal breaker that present steam power plant generally uses mainly is with the lateral surface that epitrochanterian annular is hammered into shape the coal on the broken coal plate to be smashed, and by sieve plate broken coal is exported again.But because the rounded shape of annular hammer is less with the contact-making surface that is hit coal, promptly the working face hammered into shape of annular is not fully utilized, so inefficiency, power consumption are bigger; In addition, the coal that is crashed to pieces is to pass through sieve plate by deadweight, and the sieve aperture inboard on the sieve plate is easily hung up coal, and especially wet coal is even more serious, even the part sieve aperture is blocked, and has influenced the efficient of producing coal.
The purpose of this utility model is exactly at the problems referred to above, and a kind of production efficiency height, the defeated effective coal breaker of coal are provided.
The purpose of this utility model is achieved in that the utility model comprises body, the side of the broken coal plate of body is a rotor, its structural feature is to have fan-shaped hammer on the double link of rocking arm of rotor, the broken coal plate is provided with step, is provided with the drum screen of being made up of impeller in the body of the bottom of rotor, broken coal plate.
Major advantage of the present utility model:
1, production efficiency height:
Have fan-shaped hammer on the double link of rotor of the present utility model, the movement locus of double link and the sector of fan-shaped hammer make fan-shaped hammer with the coal that is hit bigger contact be arranged, and its impulsive force is also bigger, so the production efficiency height;
2, defeated coal is effective:
The bottom of rotor of the present utility model, broken coal plate is provided with the drum screen of being made up of impeller, and the rotation of the blade of impeller impels broken coal to fall smoothly along sieve aperture, and the foreign material that can't pass sieve aperture then are transported to slag-drip opening by impeller, has improved defeated coal efficient.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of stepped plate;
Fig. 4 is the left view of Fig. 3;
Fig. 5 is the structural representation of fan-shaped hammer;
Fig. 6 is the upward view of Fig. 5.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises body 5, the side of the broken coal plate 13 of body 5 is a rotor 6, have fan-shaped hammer 9 on the double link 8 of the rocking arm 7 of rotor 6, step 12 is set on the broken coal plate 13, be provided with the drum screen of forming by impeller 31 in the body 5 of the bottom of rotor 6, broken coal plate 13.
Quadruplet symmetric double connecting rod 8 can be set, be respectively arranged with fan-shaped hammer 9 on the corresponding double link 8.
Hit in the coal body for cutting smoothly, can be provided with at the incision end of fan-shaped hammer 9 and pour inclined-plane 10 into; Be provided with dismountable wearing plate 21 above the fan-shaped hammer 9, the service life that can improve fan-shaped hammer 9.
Be provided with back-moving spring 14 in the body 5 of the side of step 12, back-moving spring 14 is connected with body 5 by adjusting nut 15.
The step 12 of stepped plate 13 is made up of vertical plane 20 and inclined-plane 19, and inclined-plane 19 is 15 ° with the angle β of vertical plane 20--and 30 °.
Narrate a course of action of the present utility model below:
Motor 18 drives rotor 6 and rotates, because action of centrifugal force, double link 8 drive fan-shaped hammer 9 along circular motion, fiercelying attack enters coal on the broken coal plate 13 from feeding mouth 11, the coal that is crashed to pieces is then from falling between broken coal plate 13, the rotor 6 on the drum screen 1 that is driven by motor 17, the broken coal that meets established standards falls from sieve aperture 2, foreign material are then discharged from slag-drip opening 16, promptly finish a course of action of the present utility model.
