Abstract

An eccentric roller crusher comprises a first eccentric roller having a first barrel and at least one first eccentric seat penetrating through the first barrel inner diameter; a first eccentric roller having a second barrel and at least one second eccentric seat penetrating through the second barrel inner diameter; and a feed barrel. The right center is disposed near the first eccentric roller and the second eccentric roller to make the gap between the first eccentric roller and the feed barrel form a feed inlet, and the gap between the second eccentric roller and the feed barrel form a discharge outlet; a feed channel is formed between the first eccentric roller and the second eccentric roller and the feed barrel; when the first eccentric seat is rotated by a first rotational speed, the first barrel is rotated by a second rotational speed, so that the first gap of the feed inlet is constantly changing; and when the second eccentric seat is rotated by a third rotational speed, the second barrel is eccentrically rotated by a fourth rotational speed to make the second gap of the discharge outlet constantly change. The eccentric roller crusher can crush stones efficiently in a labor-saving manner, and helps to reduce the failure probability.

Description

The Eccentric cylinder disintegrating machine

Technical field

The wood utility model relates to a kind of being used for the building stones of greater particle size is broken into than the stone crusher of small particle diameter with sand.

Background technology

General stone crusher consists predominantly of several to rolling wheel; have difference and be fixing gap between every a pair of rolling wheel; that is the most maximum near the gap of feeding mouth; the most minimum near the gap of discharging opening; from feeding mouth to other gap between discharging opening then sequentially by inferior large to time little; whereby; after the larger stone grain of particle diameter is knocked down feeding mouth; utilize two counterrotating rolling wheel surfaces that the stone grain is produced clamping crushing action; so that being broken into, the stone grain is suitable for building or the purpose than the small particle diameter sand grains that engineering is used; yet; because the stone grain is irregularly shaped and not of uniform size, is again very hard material, so that between two rolling wheels of fixed interval (FI), force when crushing; the slippage of stone grain is often arranged and stone grain problem not of uniform size after causing crushing, increase on foot the trouble in the sorting operations of follow-up stone grain.In addition, because the gap between two rolling wheels is fixed, cause when the stone grain of extruding greater particle size, rolling wheel must be bestowed very large active force, be stuck between the rolling wheel except frequent generation stone grain and must expend quite a lot of time pulverizes back and forth, parts are the accelerated wear test because bearing sizable active force also, is necessary maintenance in the short time, has increased the maintenance cost of machinery equipment.

The utility model content

Technical problem underlying to be solved in the utility model is, when overcoming stone crusher that prior art exists and utilizing the gap to be two fixing rolling wheels the stone grain is pushed, when running into the stone grain of greater particle size, rolling wheel must be bestowed very large active force, except there being easily the stone grain to be stuck between the rolling wheel and must expend quite a lot of time pulverizes back and forth, parts are the accelerated wear test because bearing quite large active force also, so that increased the problem of machinery equipment maintenance cost, and provide a kind of Eccentric cylinder disintegrating machine, can carry out fragmentation work, the probability of Reduction of failure to the stone grain more efficient and more effortlessly.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of Eccentric cylinder disintegrating machine, it is characterized in that, comprise: one first Eccentric cylinder, have one first cylindrical shell, at least one the first eccentric mounting that is arranged in this first cylinder internal diameter, between the internal diameter of the external diameter of this first eccentric mounting and this first cylindrical shell at least one clutch shaft bearing is set; One second Eccentric cylinder has one second cylindrical shell, and at least one the second eccentric mounting that is arranged in this second cylinder internal diameter arranges at least one the second bearing between the internal diameter of the external diameter of this second eccentric mounting and this second cylindrical shell; One feed cylinder, the positive center of circle is arranged at contiguous this first Eccentric cylinder and the second Eccentric cylinder, make the gap between this first Eccentric cylinder and this feed cylinder consist of a feeding mouth, and the gap between this second Eccentric cylinder and this feed cylinder consists of a discharging opening, this first Eccentric cylinder, then consist of a feeding channel between the second Eccentric cylinder and the feed cylinder, when this first eccentric mounting rotates with the first rotating speed, this first cylindrical shell is with the second rotating speed eccentric rotary, and then make this feeding mouth produce the first gap that constantly changes, when this second eccentric mounting rotates with the 3rd rotating speed, this second cylindrical shell is with the 4th rotating speed eccentric rotary, and then the second gap that this discharging opening generation is constantly changed; The stone grain that drops into from feeding mouth becomes building, engineering sand than small particle diameter via the first gap of aforementioned continuous variation with the second gap attrition crushing.

For reaching better stone grain crushing effect, the first eccentric mounting of the first Eccentric cylinder of the present utility model, its offset is 6mm, the excursion that causes this first gap is 2mm～14mm; And the offset of the second eccentric mounting of the second Eccentric cylinder is 4mm, and the excursion that causes this second gap is 2mm～10mm.

In order to make the first Eccentric cylinder of the present utility model and the second Eccentric cylinder obtain good vibratory impulse effect, the utility model is to make the first eccentric mounting and the second eccentric mounting produce the first rotating speed and the 3rd rotating speed of 400～500rpm, thereby make the first cylindrical shell and the second cylindrical shell produce the second rotating speed and the 4th rotating speed of 10～15rpm, produce simultaneously vibration.

The feed cylinder that attaches the stone flour dust for fear of the surface affects the feeding effect, and the utility model can be used for striking off the scraper plate of the stone flour dust on the feed cylinder wheel face arranging one below the feed cylinder, even a sparge pipe that is used for to feed cylinder wheel face water spray is set.

The utility model is that the gap that breaker plates is used for pushing between the cylinder of stone grain is made as sustainable variation, whereby, when no matter the stone grain of large particle diameter or small particle diameter enters gap between cylinder, all can keep large and small stone grain all not have the phenomenon of blocking in active state, and then make the stone grain than small particle diameter preferentially pass through the gap, squeezed being broken into than small particle diameter of process that the stone grain of greater particle size then constantly grinds and exerts pressure at cylinder, final becoming by the gap between cylinder fully built or engineering sand.

The utility model is to make cylinder produce simultaneously the vibratory impulse effect in the process of grinding extruding of rolling, and allows whereby the fragmentation of stone grain more easy.

Eccentric roller disintegrating machine of the present utility model, except can be more efficient and carry out the fragmentation work the stone grain more effortlessly, the parts of disintegrating machine stressed also can be because of reducing the probability of Reduction of failure, therefore be a utility model of very having novelty and a progressive.
