Abstract

The utility model discloses a grinding crusher, relating to the improvement of the grinding crusher structure. The utility model provides a grinding crusher with simple structure and good grinding and crushing effect, comprising a body; a motor is connected with a main shaft by a speed reducer in the body; a feed opening and a discharge opening are arranged at the upper part of the body and a grinding cover is arranged at the lower part of the body. The utility model is characterized in that an upper bracket and a lower bracket are respectively arranged at the upper part and the lower part of the main shaft sleeve; a countershaft is fixed between an upper supporting arm of the upper bracket and a lower supporting arm of the lower bracket; a grinding ring that can contact the grinding cover is sleeved on the countershaft sleeve between the upper supporting arm and the lower supporting arm.

Description

A kind of abrading type disintegrator

Technical field:

The utility model relates to the improvement of abrading type disintegrator structure.

Background technology:

At present, normally used Suspension roller grinding and crushing machine, its primary structure are to be hung with the mill hammer on the support of main shaft upper end; During work, main shaft drives the centrifugal rotation of mill hammer, and the mill cover of mill hammer on body produces frictional force, pulverizes or levigate processed material between mill hammer and mill cover.But there is following shortcoming in this structure, because the mill hammer in case foozle or alignment error are arranged, can cause processed material unbalance stress for all-in-one-piece; In addition, the bed of material uneven distribution of processed material, the mill hammer during thick bed of material place jack-up is rotated, and the thin bed of material does not reach the mill hammer, and can't be stressed, had a strong impact on and pulverized or levigate effect.Be this structure more complicated again, bring very big trouble for manufacturing, installation, maintenance.

The utility model content:

The utility model is exactly at the problems referred to above, provides a kind of simple in structure, the abrading type disintegrator that pulverize, grinding effect is good.

The utility model adopts following technical scheme: the utility model comprises body, motor links to each other with main shaft by the reductor in the body, the body top is respectively arranged with charging aperture, discharging opening, the body below is the mill cover, the top of the axle sleeve of its structural feature main shaft, below are fixed with upper bracket, lower carriage respectively, be fixed with countershaft between the upper branch arm of upper bracket and the lower branch arm of lower carriage, the countershaft between upper branch arm, the lower branch arm is with the bull ring that can touch the mill cover outward.

The beneficial effects of the utility model:

1, simple in structure:

The utility model is mainly done on the existing structure basis to improve, and is about to existing suspension type mill hammer, changes into around the bull ring of main axis rotation and pulverizing, and grinds processed material; Its member is few, and simple, is easy to make, and is easy to installation, maintenance etc.;

2, improve pulverizing, grinding effect:

Bull ring of the present utility model can be a plurality of settings, not only makes material to be machined stressed evenly, and does not have the dead angle, therefore, pulverizes, grinding effect is good;

3: the efficient height:

Bull ring of the present utility model can be a plurality of settings, can make processed material stressed big and reasonable, and its levigate quality is considerably beyond existing grinding and crushing machine; And through facts have proved, the utility model is saved electric power than existing grinding and crushing machine and can be reached more than 30%.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the bull ring of Fig. 1 is the partial enlarged drawing of circular bull ring;

Fig. 3 is that circular bull ring homophase closes the part-structure schematic diagram;

Fig. 4 is that the bull ring of Fig. 1 is the partial enlarged drawing of arc bull ring;

Fig. 5 is arc bull ring and relevant portion structural representation.

The specific embodiment:

The utility model comprises body 12, motor 1 links to each other with main shaft 8 by the reductor 2 in the body 12, body 12 tops are respectively arranged with charging aperture 11, discharging opening 13, body 12 belows are mill cover 5, the top of the axle sleeve 7 of main shaft 8, below are fixed with upper bracket 9, lower carriage 3 respectively, be fixed with countershaft 6 between the upper branch arm 14 of upper bracket 9 and the lower branch arm 16 of lower carriage 3, the countershaft 6 outer bull rings 4 that can touch mill cover 5 that are with between upper branch arm 14, the lower branch arm 16.

Upper branch arm 14 can be 3-4, and corresponding lower branch arm 16 is 3-4.

The number of bull ring 4 can be set as required; Usually bull ring 4 can be 6-10.Corresponding to the change of the number of bull ring 4, axle sleeve 7 also can be a plurality of; Can be convenient to install, use.

Bull ring 4 can be circular bull ring 15.Bull ring 4 also can be arc bull ring 17; The endoporus of arc bull ring 17 with between the countershaft 6 for movingly; Can process the material of toughness.

Nut 10 is fixed in upper bracket 9, lower carriage 3 on the main shaft 8.

Below in conjunction with a description of drawings course of action of the present utility model:

At first, starter motor 1 drives main shaft 8 by reductor 2 and rotates, and the countershaft 6 between the upper branch arm 14 of main shaft 8 drive upper brackets 9, the lower branch arm 16 of lower carriage 3 rotates.Countershaft 6 drives circular bull ring 15 revolution, and circular bull ring 15 is also in rotation simultaneously, meanwhile, and the material application of force, pulverizing or levigate processed materials between 15 pairs of mill covers 5 of circular bull ring and the circular bull ring 15; Or countershaft 6 drives arc bull ring 17, the material application of force between 17 pairs of mill covers 5 of arc bull ring and the arc bull ring 17, pulverizing or levigate processed material.
