Compared with the prior art, the invention has the following advantages:
in the invention, the included angle between the circle center connecting line of the same section of the driving roller and the driven roller and the negative direction of the X axis of the section is beta, and beta is more than 75 degrees and less than 90 degrees; the structure leads people to construct a structure that the driving roller presses the driven roller, the pressing force is realized by the gravity of the driving roller, the pressing force is very useful when crushing stone, and can play a reliable crushing effect, and meanwhile, as other transmission structures are not needed to drive the driven roller to rotate and larger driving motor power is not needed to clamp the crushed stone, the structure has very good energy-saving effect;
the distance between the closest points of the circumferential surfaces of the same section of the driving roller and the driven roller is D, and D is more than or equal to 0 and less than or equal to 3 mm; regarding the adjustment of the distance, the adjustment can be realized by arranging a limiting device on the machine frame to limit the lowest point of the driving roller towards the driven roller; when the limiting device is not set, the D is 0; at the moment, the roller is abraded greatly, but the roller also has a better crushing effect; when D is more than 0 and less than or equal to 3mm, smaller roller loss can be obtained, and noise can be reduced; all this becomes freely adjustable due to the limitation on D;
in the invention, the end shafts of the driving roller at two sides of the driving roller are rotatably arranged on a rotary arm; the rotary arm is rotatably arranged on a bearing of the rotary bearing seat through a rotary shaft; therefore, the driving roller swings integrally by taking the rotation center of the rotating arm as a rotating shaft, and is close to or far away from the driven roller, so that the adjustment of pressing and loosening is realized;

As shown in the figure, it is preferable that the diameter of the passive roller is larger than that of the active roller or the diameter of the passive roller is smaller than that of the active roller. In this point, the traditional structure is that the diameters of two rollers are generally the same, but the two rollers are positioned on a uniform horizontal plane, so that the meaning that the diameters of the two rollers are different is not large; the arrangement form of the driving roller and the driven roller leads the diameter of the driven roller to be larger than that of the driving roller, so that the advantages of more convenient charging and easier feeding of stone into the gap are obviously brought; if the diameter of the driven roller is smaller than that of the driving roller, the driving roller can crush the stones more easily; generally, we will choose a structure with a diameter of the passive roller larger than that of the active roller.
As shown in the figure, preferably, the rotating arm at the end of the driving roller, which is not provided with the reducer, is provided with a balancing weight. On one hand, the two ends of the driving roller are more balanced by the balancing weight, and the pressure of the driving roller is increased;
