Referring to fig. 1-2, the present invention provides a whole and partial structure diagram of an embodiment of the present invention, specifically disclosing a crushing device, comprising:

the box body 01 is rectangular, the bottom of the box body 01 is open, and a rectangular feed inlet 010 is formed in the top surface of the box body 01;

the outer peripheral sides of the driving roller 02 and the driven roller 03 are respectively and uniformly provided with a plurality of annular teeth with rectangular cross sections in an integrated forming way along the axial direction, the annular teeth on the driving roller 02 and the annular teeth on the driven roller 03 are sequentially staggered and mutually occluded, the driving roller 02 and the driven roller 03 are arranged in the box body 01, the plane formed by the axes of the driving roller 02 and the driven roller 03 is parallel to the top surface of the box body 01, the end part of the driving roller 02 is sleeved along the axis and is fixedly provided with a rotating shaft I04 by welding, the end part of the driven roller 03 is sleeved along the axis and is fixedly provided with a rotating shaft II 05 by welding, one end of the rotating shaft I04 penetrates through the side wall of the box body 01 and is sleeved with a belt pulley 06, the other end of the rotating shaft II 04 penetrates through the side wall of the box body 01 and is sleeved with a gear I07, one end of the rotating shaft II 05 penetrates through the side wall of the box body 01 and is sleeved with a gear II 08, and the other end of the rotating connecting with the side wall of the box body 01, the first gear 07 is meshed with the second gear 08.

More specifically, a first rectangular scraper 09 and a second rectangular scraper 10 are installed inside the box 01, the ends of the first rectangular scraper 09 and the second rectangular scraper 10 are respectively fixed to two pairs of side edges of the box 01 through bolts, the plate length directions of the first rectangular scraper 09 and the second rectangular scraper 10 are respectively parallel to the axial lines of the driving roller 02 and the driven roller 03, and one side edge of the first rectangular scraper 09 and one side edge of the second rectangular scraper 10 are respectively in contact with the outer side walls of the driving roller 02 and the driven roller 03 and are in shape fit with the outer side walls of the driving roller 02 and the driven roller 03.

More specifically, the first scraper 09 and the second scraper 10 are symmetrically arranged around the feed inlet 010, and the first scraper 09 intersects with the extended surface of the second scraper 10 and the intersecting position is located below the box body 01.

Further specifically, the feed inlet 010 corresponds to the position where the outer side walls of the driving roller 02 and the driven roller 03 are meshed with each other.

More specifically, the number of teeth in gear one 07 is less than the number of teeth in gear two 08.

The working principle of the crushing device is as follows:

it is not shown in the figure to be connected the drive arrangement belt through belt pulley 06 and this device outside and realize the drive to driving roller 02, because gear 07 is installed to a tip of driving roller 02, gear 08 is installed to driven roller 03's one end, and gear 07 and gear 08 intermeshing, so, driven roller 03 also can rotate and with driving roller 02's rotation direction opposite, driving roller 02 and driven roller 03 rotate relatively, will take broken material to drop into box 01 from feed inlet 010 department, because driving roller 02 and driven roller 03 rotate relatively and set gradually the cyclic annular tooth of interlock mutually on the lateral wall of the two, so can carry out effectual breakage to the material, after the breakage is accomplished, broken material powder sediment drops from the box 01 bottom. Because the material is different, some probably block up or the adhesion is on initiative running roller 02 or driven running roller 03, owing to be provided with scraper blade 09 and scraper blade 10 two, so, can be in time with the material clean up of adhesion on initiative running roller 02 and driven running roller 03 lateral wall, guarantee the crushing effect of material. And because the tooth number of the gear I07 is different from that of the gear II 08, a certain rotating speed difference exists between the driving roller 02 and the driven roller 03, and the device can play a self-cleaning function and also improve the crushing effect of the device.
