Further, the driving module is a speed reduction motor.

Further, the device also comprises an overload protection device which is electrically connected with the electronic control module.

The beneficial effect of adopting the further scheme is that: the overload protection device for the speed reducing motor is installed, when the speed reducing motor is stuck due to excessive cuttings or other emergency situations, an alarm can be sent in time, a power supply is cut off, and the phenomenon that the speed reducing motor is burnt out due to overheating caused by the sticking is effectively avoided.

Further, the roller blades are spaced circumferentially around the shredder shaft.

The beneficial effect of adopting the further scheme is that: the cutter of the crusher is installed at intervals, and is installed on the crusher shaft in a surrounding mode at four sides, so that the quantity of the roller cutters at the shearing position at the same moment can be reduced, the roller cutters are prevented from being at the shearing position at the same time, and the overload condition of the speed reduction motor is greatly reduced.

Further, the trench is U-shaped.

The beneficial effect of adopting the further scheme is that: the shearing positions of the roller knife and the barbs can be increased, and the crushing efficiency is improved.

Still further, an upper row of devices is included for lifting cuttings and waste liquid from the trench into the collection device.

The beneficial effect of adopting the above further scheme is that: effectively avoiding the problems of incapability of conveying cuttings, blockage of pipelines and the like.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 and 2, the crushing device comprises a crushing main body 1, barbs 2, a transmission module 4, a driving module and an electric control module;

the crushing main body 1 is arranged in a trench 3 and comprises a crusher shaft 1-1 and roller cutters 1-2, wherein the roller cutters 1-2 are fixed on the crusher shaft 1-1 of the crushing main body 1, and two ends of the crusher shaft 1-1 are rotatably arranged on the side wall of the trench; the barb 2 is fixed on the bottom wall of the trench; the roller cutters 1-2 are arranged around the crusher shaft 1-1 in a staggered surrounding mode at intervals, only a few roller cutters 1-2 and the barbs 2 are located at a shearing position at the same time, and the situation that a plurality of roller cutters are located at the shearing position at the same time is avoided, so that the instantaneous working pressure of the crusher shaft 1-1 is greatly reduced, and the requirement on driving force is reduced; the transmission module 4 comprises a chain and a chain wheel, and is in meshing transmission with the chain and the chain wheel; the driving module is arranged on the ground and comprises a speed reducing motor 5, and the speed reducing motor 5 is in transmission connection with the crusher shaft 1-1 through the transmission module; the electric control module controls the speed reducing motor 5 to rotate forwards or backwards; the overload protection device is electrically connected with the electric control module, and the trench 3 is U-shaped; an upper drain is included for lifting cuttings and waste liquid from the trench into the collection device.

To realize crushing the long-strip-shaped scraps of the numerical control machine tool, when the roller cutters 1-2 rotate to pass through the barbs 2, effective shearing can be formed, and the scraps are crushed, wherein the roller cutters 1-2 and the barbs 2 are subjected to special treatment, so that the hardness of the scraps is increased.

The crushing main body 1 is arranged in a trench 3, when iron chips enter the operation range of the crushing main body 1, the speed reduction motor 5 drives the crusher shaft to rotate so as to drive the roller cutters 1-2 to rotate, when the roller cutters 1-2 rotate through the barbs 2, long chips are crushed by utilizing shearing force generated by relative motion, the chips and cooling waste liquid of a machine tool are discharged into the trench 3 and then collected to an upper discharging device, and the chips and the waste liquid are conveyed together into a concentrated pipeline by the upper discharging device.

The driving module is arranged on the ground and comprises a speed reducing motor 5, the speed reducing motor 5 is in transmission connection with the pulverizer shaft 1-1 through the transmission module 4, the rotation mode of the speed reducing motor 5 is controlled by the electric control module, and after the speed reducing motor is started, the speed reducing motor rotates forwards or backwards alternately.

When the material of bits type and bits changes, can adjust rubbing crusher corotation and reversal time through adjusting the time relay button in the electric cabinet. When the chips are blocked excessively, the speed reducing motor 5 rotates in the opposite direction immediately to solve the problem, and after the problem is solved, the speed reducing motor 5 can continue to work normally to avoid the motor from being damaged due to rotation blockage.

When the gear motor 5 still can't get rid of the jam problem through reversing many times, the overload protection device of installation on gear motor 5 can in time send out the warning to cut off the power, the suggestion staff handles the problem, avoids forcing work to lead to the motor to burn out.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
