Description

A kind of double-roll crusher

Technical field

The utility model relates to crushing plant technical field more particularly to a kind of double-roll crushers.

Background technique

Crusher is widely used in the industries such as coal, metallurgy, mine, chemical industry, building materials, and common pulverizer has roll-type, hammer Chip, roll flute formula, grinding formula etc..Existing double-roll crusher when broken, be crushed spacing it is non-adjustable, and crushing efficiency compared with Low, there is also the short defects of service life.

Utility model content

The purpose of this utility model is to provide a kind of double-roll crusher for the deficiency in above-mentioned background technique, to solve The technical problem that double-roll crusher crushing efficiency is low, service life is short in the prior art.

To achieve the above object, the utility model uses the following technical solution:

A kind of double-roll crusher, including rack, frame top open up feed inlet, and bottom opens up discharge port, the rack packet At least one fragmentation cell is included, the fragmentation cell includes horizontally disposed first fixed plate and the second fixation being vertically arranged Plate is horizontally fixed with the first broken shaft by bearing in first fixed plate, is fixed in second fixed plate by bearing It is fixedly installed the second broken shaft, breaker roll is fixedly connected on first broken shaft and the second broken shaft, and two broken Roller intermeshing, one end of first broken shaft stretch out the rack and are fixedly connected with belt pulley, the belt pulley in end It is connected to motor by driving belt, the motor is fixedly mounted on motor cabinet.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model provides a kind of double-roll crusher, and the utility model is broken single by setting multiple groups on the rack Member, each fragmentation cell can individually carry out being crushed or being classified being crushed, to improve crushing efficiency；Fragmentation cell simultaneously It is solid by bearing level in first fixed plate including horizontally disposed first fixed plate and the second fixed plate being vertically arranged Surely there is the first broken shaft, the second broken shaft is fixedly installed by bearing in second fixed plate, so that two The Impact direction of broken shaft is different, be specially fixedly mounted on the first broken shaft in horizontally disposed first fixed plate by Power is vertical direction, and the Impact direction for being fixedly mounted on the second broken shaft being vertically arranged in the second fixed plate is level side To, therefore in shattering process, when breaker roll discontinuity or excessive stress, two broken shafts can it is respective by Occur faint deformation on power direction, so as to reduce the abrasion of breaker roll in the case where stress is extreme, while reducing event Barrier rate improves the service life of crusher.

Detailed description of the invention

Fig. 1 is the main view of the utility model；

Fig. 2 is the side view of the utility model.

Specific embodiment

The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.

As depicted in figs. 1 and 2, as a kind of preferred embodiment, the utility model proposes a kind of double-roll crushers, including Rack 10, frame top open up feed inlet, and bottom opens up discharge port, and the rack 10 includes at least one fragmentation cell 20, institute Stating fragmentation cell 20 includes horizontally disposed the second fixed plate 22 first fixed plate 21 and be vertically arranged, first fixed plate First broken shaft 23 is horizontally fixed with by bearing on 21, is fixedly installed by bearing in second fixed plate 22 Breaker roll is fixedly connected on sledging axis 24, first broken shaft 26 and the second broken shaft 24, and two breaker rolls are mutual Engagement, one end of first broken shaft 23 stretch out the rack 10 and are fixedly connected with belt pulley in end, and the belt pulley is logical It crosses driving belt 25 to connect with motor 26, the motor 25 is fixedly mounted on motor cabinet 27.

In above scheme, fragmentation cell 20 includes horizontally disposed the second fixed plate first fixed plate 21 and be vertically arranged 22, the first broken shaft 23 is horizontally fixed with by bearing in first fixed plate 21, passes through axis in second fixed plate 22 It holds and is fixedly installed the second broken shaft 24, so that the Impact direction of two broken shafts is different, specially fixed The stress for being mounted on the first broken shaft 23 in horizontally disposed first fixed plate 21 is vertical direction, and is fixedly mounted on and sets vertically The Impact direction for setting the second broken shaft 24 in the second fixed plate 22 is horizontal direction, therefore in shattering process, when broken When roller discontinuity or excessive stress, faint deformation can occur on respective Impact direction in two broken shafts, from And the abrasion of breaker roll can be reduced in the case where stress is extreme, while reducing failure rate, improve the service life of crusher.

Preferably, the rack 10 includes two fragmentation cells 20, and two fragmentation cells are arranged vertically, and two broken Drainage device 30 is additionally provided between broken unit, the drainage device 30 includes two inclined drainage plates 31, described two to draw Flowing plate 31 is respectively fixedly connected on two side plates of rack 10, and described two drainage plates 31 are towards the center of two breaker rolls Place；The drainage plate 31 is made of stainless steel material, and the tilt angle of the drainage plate 31 is 30 °.Drainage device 30 is set Effect is to use two fragmentation cells in this programme to carry out graded crushing, and two fragmentation cells up and down can be set as needed The tooth grain size of middle breaker roll, so that crushing efficiency is improved to the greatest extent, it is broken single in higher level due to being provided with drainage device Member carries out after being tentatively crushed, and by the effect of drainage device, preliminary broken material can be made to entirely fall in junior broken Sufficiently broken, the stuck situation in gap of the reduction material between breaker roll and rack, in raising crushing efficiency is carried out in unit While, the abrasion of rack is decreased, the service life of crusher is extended.

Preferably, second broken shaft 24 is mounted in bearing block 28, the bearing block 28 is fixedly connected on In two fixed plates 22, and it is vertically arranged with top plate 40 in the rack 10, buffer spring 41, institute are fixedly connected on the top plate 40 The end for stating buffer spring 41 is connected on the end cap of the bearing block 28.It can be made by the way that buffer spring 41 is arranged broken In the process, the second broken shaft has enough elastic spaces, plays the role of protecting breaker roll while preventing stuck, mention again The crushing efficiency and service life of high crusher.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
