In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in many ways different from those described herein, and it will be apparent to those skilled in the art that similar modifications may be made without departing from the spirit of the utility model, and the utility model is therefore not limited to the specific embodiments disclosed below.

In the present invention, the term "comprising" means that the element preceding the term covers the element listed thereafter, and does not exclude the possibility of also covering other elements; "upper, lower, front, rear" and the like are used only to indicate relative positional relationships, and when the absolute position of the object to be described is changed, the relative positional relationships may also be changed accordingly; "connected" and the like are used to indicate that the components may be directly connected to each other or may be connected to each other through intervening components.

As shown in fig. 1 to 3, a shear crusher comprises a housing 1, a crushing device 2 disposed inside the housing, a driving device 3, and a pressing device 4, wherein the pressing device comprises a pusher 41 and an inspection shutter 42, the pressing device is located above the crushing device, and the pusher 41 is used for conveying materials;

the crushing device 2 comprises a first cutter disc 21, a first cutter shaft, a second cutter disc 22 and a second cutter shaft, wherein the first cutter disc 21 and the second cutter disc 22 are fixed on the first cutter shaft and the second cutter shaft in a welding or threaded connection mode; the first cutter shaft and the second cutter shaft are respectively provided with a first cutter disc and a second cutter disc which are the same in number;

the driving device 3 comprises a first hydraulic motor 31 and a second hydraulic motor 32, wherein the first hydraulic motor 31 is positioned at the rear end of the shell 1, and the second hydraulic motor is positioned at the front end of the shell 1;

the driving device 3 further comprises a bearing seat assembly, a first hydraulic motor 31 and a second hydraulic motor 32 which are in splined connection with the first spline shaft and the second spline shaft are respectively fixed on the end faces of the first bearing seat assembly and the second bearing seat assembly, the other ends of the first spline shaft and the second spline shaft are respectively meshed with a first internal spline sleeve and a second internal spline shaft sleeve, and the first internal spline sleeve and the second internal spline sleeve are respectively connected with the first cutter shaft and the second cutter shaft, so that the driving device drives the crushing device to rotate; the first cutter shaft with the first cutter head and the second cutter shaft with the second cutter head rotate oppositely.

As shown in fig. 3, the number of cutter teeth on the first cutter disc is different from that on the second cutter disc. For example: the quantity of sword tooth is 9 teeth on the first blade disc, and the quantity of sword tooth is 7 teeth on the second blade disc, can effectually reduce broken back material granularity overlength through setting up the blade disc of different tooth numbers. Of course, the number of the cutter teeth on the first cutter disc and the second cutter disc can also be the same.

The control component (not shown) comprises a sensor and an automatic control system which are electrically connected, the first hydraulic motor 31 and the second hydraulic motor 32 are respectively provided with a first sensor and a second sensor, and the automatic control system is connected with an overhaul gate plate in the material pressing device.
