Description
Technical field
The present invention relates to a kind of sand equipment processed, especially a kind of double lever disintegrating machine.
Background technology
Usually need building stones broken in sand processed is produced, existing disintegrating machine type generally includes alligator, gyratory crusher and impact crusher.The advantage of alligator is that to have cheap, structure simple, but it is large to there are dental lamina wearing and tearing, and within general two days, need align once, glitch is many, yields poorly, and the shortcoming such as the particle shape of stone aggregate is bad; Although gyratory crusher has, output is higher, the good advantage of aggregate particle shape, the deficiency such as have that cost is high, large, the power of motor of maintenance difficulty is large, liner plate abrasion is large, require the aggregate that enters less; Impact crusher also has the advantage that output is high, aggregate material shape is good, but also have that cost is high, liner plate and tup abrasion cause greatly the shortcomings such as the number of times increase of overhauling.
In order to solve the problem, market there is a lot of double-roll crusher, the such as patent No. be 03129664.5 name be called double-roll crusher, its great advantage is that two rollers relatively rotate with different rotating speeds; Movable roller diameter is greater than fixing roller diameter.Again the such as patent No. be 200510000361 name be called double-roll crusher, its great advantage is that stationary roll is identical with the structure of movable roll, its surface is all designed with the crushing teeth forming Spiral distribution along axis, and the crushing teeth of two rollers is engaged makes move toward one another.
Above-mentioned two improvement of patent emphasis point all on two roller, other structures and prior art basic simlarity, stationary roll is directly fixed in frame, is inserted with pad between stationary roll and movable roll, is used for adjusting discharge gate gap.Spring and adjusting bolt is had after movable roll, when can not be broken hard ware material or metal derby fall into time, spring is compressed, movable roll moves backward or slides, hard ware material is drawn off, then make movable roll set back again by spring force, when can not broken hard ware material or metal derby too much or excessive easily stuck.
The material entering disintegrating machine in said structure wants to be broken, and needs certain extruding force, so spring must be in compressive state, there to be enough spring forces (about about 10 tons) to act on roller, with satisfied broken needs.And in the structure of existing double-roll crusher, this huge spring force has also indirectly been pressed on pad, so when regulating discharge gate gap, inserting or extracting pad very difficult, adding adjustment difficulty.In addition, existing double-roll crusher is after the adjustment of discharge gate gap, and the active length of spring changes, spring force there occurs change, in order to ensure the extruding force needed for fragmentation, needing again adjusting bolt to readjust spring works length, making adjustment work become loaded down with trivial details.
Summary of the invention
The object of the present invention is to provide a kind of structure simple and the good double lever disintegrating machine of crushing effect.
To achieve these goals, the present invention adopts following technical scheme:
A kind of double lever disintegrating machine, comprise frame, also comprise and be arranged on hopper in described frame and one end and be hinged on the first lever in described frame and the second lever, the other end of described first lever and described second lever is all provided with pressue device, and the shaft of described first lever and described second lever is rotatably connected to respectively the first action roller wheel and the second action roller wheel, the position of described first action roller wheel is higher than described second action roller wheel, described first action roller wheel below is provided with to take turns with described first action roller and described second action roller is taken turns the fixed roll coordinated and taken turns, described fixed roll wheel is rotatably connected in described frame, and described first action roller wheel and described second action roller wheel can be fitted on described fixed roll wheel under the effect of described lever, described frame is also provided with the first motor for driving described first action roller wheel to rotate, the second motor rotated for driving described second action roller wheel and the 3rd motor for driving described fixed roll to take turns rotation, described first action roller wheel is identical with the rotation direction of described second action roller wheel, the rotation direction of described first action roller wheel or described second action roller wheel is contrary with the rotation direction that described fixed roll is taken turns, the position of described hopper is higher than described first action roller wheel, the discharging opening of described hopper is provided with the passage of taking turns cooperation place for the building stones in described hopper being delivered to described first action roller wheel and described fixed roll.
Adopt technique scheme, by pressue device activation lever, the first action roller wheel and the second action roller wheel are pressed on fixed roll wheel, roll-in is carried out to the sandstone between action roller wheel and fixed roll wheel, by being positioned at the below of action roller wheel due to the first fixed roll wheel, first action roller wheel can also roll the sandstone be positioned on fixed roll wheel, structure is simple, and through roll-in and the double action that rolls, crushing effect is better.
As a modification of the present invention, described pressue device is gasbag pressurizes device or hydraulic pulldown.By above-mentioned improvement, pressue device is made to have certain shock-absorbing capacity, avoid comparatively hard stone damage action roller wheel or fixed roll wheel, particularly the induction of gasbag pressurizes device is comparatively sensitive, when material is too much or too hard, action roller can be allowed to take turns under the reaction force of material toward the direction motion away from fixed roll wheel, make material can driven running roller and fixed roll take turns between drop.
As a modification of the present invention, described first motor and described action roller are connected with the first speed changer between taking turns, described second motor and described fixed roll are connected with the second speed changer between taking turns, and described 3rd motor and described fixed roll are connected with the 3rd speed changer between taking turns.By above-mentioned improvement, the rotating speed of the first action roller wheel, the second action roller wheel and/or fixed roll wheel can be adjusted according to the soft durometer of sandstone, improve crushing effect further.
As a modification of the present invention, described frame is provided with the material scraping plate for being struck off by the sizing on described action roller wheel and/or described fixed roll wheel.By above-mentioned improvement, can be used for removing the sizing on action roller wheel and/or fixed roll wheel, avoid sizing to affect crushing effect
