Abstract

The invention provides a blocking preventing type coal crusher. The blocking preventing type coal crusher comprises a box body. The blocking preventing type coal crusher is characterized in that driving coal crushing rollers and driven coal crushing rollers are arranged in the box body; teeth on the driving coal crushing rollers and the driven coal crushing rollers are staggered; a coal inlet is formed above a part, where one driving coal crushing roller and the corresponding driven coal crushing roller are intersected, on the box body; a coal outlet is formed below the part where another driving coal crushing roller and the corresponding driven coal crushing roller are intersected; two end shafts of the driving coal crushing rollers are correspondingly fixed to two sides of the box body through bearings, and one end shaft extends out of the box body and is connected to an output shaft of a motor through a coupling; two end shafts of the driven coal crushing rollers pass through chutes which are horizontally formed in the two sides of the box body, and the two end shafts are fixed into connecting sleeves through the bearings; the connecting sleeves are connected to piston rods which are horizontally telescoped in hydraulic cylinders; hydraulic cylinder bodies are positioned in hydraulic cylinder retainers. With the adoption of the blocking preventing type coal crusher, large coal blocks can be effectively prevented from blocking between the driving coal crushing rollers and the driven coal crushing rollers.

Description

A kind of anti-clogging coal breaker
Technical field:
The present invention relates to a kind of coal breaker, be specifically related to a kind of anti-clogging coal breaker.
Background technology:
Coal breaker is the necessary devices in coal production, its granular size that coal crusher can be become require, but colliery enters after in casing and easily causes blocking, not only affect the operating efficiency of disintegrating machine, affect normally carrying out of crushing operation, also can cause the roller tooth on broken coal roller and greatly wear and tear, increase production maintenance cost.
Summary of the invention:
The present invention, for overcoming the deficiencies in the prior art, provides a kind of anti-clogging coal breaker, and it can effectively prevent gathering coal blocking between active broken coal roller and passive broken coal roller.
Anti-clogging coal breaker of the present invention, comprise casing, technical scheme adopted for achieving the above object is: be provided with initiatively broken coal roller and passive broken coal roller in described casing, roller tooth interlaced arrangement initiatively on broken coal roller and passive broken coal roller, casing the has the initiative top of broken coal roller and passive broken coal roller intersection offers coal feed point, the have the initiative below of broken coal roller and passive broken coal roller intersection offers coal outlet, the two end axles of described active broken coal roller is fixed on the both sides of casing by bearing, wherein one end shaft extension is gone out casing and is connected with the output shaft of motor by shaft coupling, the chute that the two end axles of described passive broken coal roller is offered through casing both sides level is also fixed in adapter sleeve by bearing, adapter sleeve is connected with the piston rod of horizontal extension in hydraulic cylinder, the cylinder body of hydraulic cylinder is in hydraulic cylinder retainer.
As a further improvement on the present invention, described active broken coal roller is arranged above and below and is provided with two, and be in and do not establish the end of on the side of the casing of motor two active broken coal rollers to be respectively equipped with delivery wheel, two delivery wheels are connected by conveyer belt.
As a further improvement on the present invention, described passive broken coal roller is arranged above and below and is provided with two, and the passive broken coal roller being in upside, with initiatively broken coal roller level is corresponding, is in the passive broken coal roller of downside with initiatively broken coal roller level is corresponding.
The invention has the beneficial effects as follows: the present invention moves by active broken coal roller strap the coal cinder entered in casing and runs downwards, coal cinder runs downwards and drives passive broken coal roller to run downwards, roller tooth initiatively on broken coal roller and passive broken coal roller rolls coal cinder, thus reach the object of broken coal, under normal broken coal state, the piston rod of hydraulic cylinder supports passive broken coal roller and keeps constant spacing with active broken coal roller, when there being bulk coal cinder blocking between active broken coal roller and passive broken coal roller, the thrust that passive broken coal roller overcomes piston rod under the extruding of coal cinder is run backward along chute, thus the coal cinder of blocking is fallen, reach the object preventing coal cinder blocking.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is side view of the present invention;
Fig. 3 is top view of the present invention.
Detailed description of the invention:
With reference to each accompanying drawing, this anti-clogging coal breaker, comprise casing 1, initiatively broken coal roller 2 and passive broken coal roller 3 is provided with in described casing 1, initiatively broken coal roller 2 and the roller tooth interlaced arrangement on passive broken coal roller 3, casing 1 the has the initiative top of broken coal roller 2 and passive broken coal roller 3 intersection offers coal feed point 4, the have the initiative below of broken coal roller 2 and passive broken coal roller 3 intersection offers coal outlet 13, the two end axles of described active broken coal roller 2 is fixed on the both sides of casing 1 by bearing, wherein one end shaft extension is gone out casing 1 and is connected by the output shaft of shaft coupling 5 with motor 6, the chute 7 that the two end axles of described passive broken coal roller 3 is offered through casing 1 both sides level is also fixed in adapter sleeve 8 by bearing, adapter sleeve 8 is connected with the piston rod 9 of horizontal extension in hydraulic cylinder, the cylinder body of hydraulic cylinder is in hydraulic cylinder retainer 10.Described active broken coal roller 2 is arranged above and below and is provided with two, and be in and do not establish the end of two on the side of the casing 1 of motor 6 active broken coal rollers 2 to be respectively equipped with delivery wheel 11, two delivery wheels 11 are connected by conveyer belt 12.Described passive broken coal roller 3 is arranged above and below and is provided with two, and the passive broken coal roller 3 being in upside, with initiatively broken coal roller 2 level is corresponding, is in the passive broken coal roller 3 of downside with initiatively broken coal roller 2 level is corresponding.
Starter motor 6, when coal cinder is entered into after in casing 1 by coal feed point 4, along with the rotation of active broken coal roller 2 runs downwards, passive broken coal roller 3 is driven to rotate downwards when coal cinder runs, be broken under the effect of the roller tooth of coal cinder on active broken coal roller 2 and passive broken coal roller 3, thus realize the object of broken coal, when there being the coal cinder blocking of bulk between active broken coal roller 2 and passive broken coal roller 3, passive broken coal roller 3 can move backward along chute 7 under the extruding of coal cinder, thus the space expanded initiatively between broken coal roller 2 and passive broken coal roller 3, coal cinder is fallen in both spaces, thus prevent coal cinder blocking.
