Referring to fig. 1 to 4, the present invention discloses a crusher, which comprises a housing 10 and two knife rolls 20; the shell 10 is provided with a crushing cavity 13, and the crushing cavity 13 is provided with an upper feeding port 11 and a lower discharging port 12; each knife roller 20 is arranged between the upper feeding hole 11 and the lower discharging hole 12; the knife roll 20 comprises a rotating shaft 21 which can be rotatably arranged and a crushing knife 22 which is arranged on the rotating shaft 21; the crushing blade 22 has a blade 2211, and the blade 2211 has a V-shaped cross section; the waste material passes through the space between the two rotating shafts 21; when the crushing device is used, the waste materials bound by the steel wires are fed into the crushing cavity 13 through the upper feeding port 11, the two rotating shafts 21 rotate, the waste materials of the steel wires move downwards through the space between the two rotating shafts 21, at the moment, the section of the cutting edge 2211 is V-shaped, the cutting edge 2211 is sharp, the crushing knife 22 simultaneously crushes the steel wires and the waste materials together, the crushing of the waste materials bound by the steel wires is completed in one step, the operation of detaching the steel wires is omitted, the crushing flow is simplified, and the efficiency is improved; at the same time, the crushing blades 22 are sharper to facilitate rapid shredding of waste material, further improving efficiency.

It is worth mentioning that the crushing blade 22 may be made of a material having a hardness greater than or equal to that of the steel wire, such as steel, cemented carbide, etc., which can ensure the quality and prevent the crushing blade 22 from breaking the steel wire.

The crushing knife 22 of the present embodiment has at least two blades 2211, and the at least two blades 2211 are sequentially arranged at intervals along the circumferential direction of the rotating shaft 21, so that when the rotating shaft 21 rotates for one circle, each crushing knife 22 has at least two crushing effects, and the crushing efficiency can be improved.

Further, the crushing knives 22 are of an axisymmetric structure, each crushing knife 22 is provided with two cutting edges 2211, and the two cutting edges 2211 are symmetrically arranged about the symmetry axis of the crushing knife 22; here, the crushing blade 22 has an axisymmetric structure, which simplifies the processing difficulty of the crushing blade 22.

Specifically, the crushing cutter 22 includes a cutter base 222 disposed on the rotating shaft 21 and two cutter bodies 221 respectively disposed on the left and right sides of the cutter base 222; the angle of each blade body 221 away from the cutting edge 2211 and the rotating shaft 21 is formed into a cutting edge 2211; therefore, axial symmetry is realized, two blades 2211 are formed, and the structure is simple and easy to realize.

Specifically, the tool holder 222 is square and has a certain thickness to improve strength.

The cutter body 221 of the present embodiment is detachably disposed on the cutter holder 222, and the cutter body 221 is easily repaired and replaced by detaching the cutter body 221; here, for convenience of understanding, the cutter body 221 closest to the other cutter roll 20 on the cutter body 221 of any one of the cutter rolls 20 is referred to as a front cutter body 221, and the cutter body 221 farthest from the other cutter roll 20 is referred to as a rear cutter body 221, so that the front cutter body 221 contacts the steel wire more frequently than the rear cutter body 221 in use, and the wear of the front cutter body 221 is greater than that of the rear cutter body 221 in long-term use, and at this time, since the crushing cutter 22 has an axisymmetric structure, the use of the crushing cutter 22 is not affected after the cutter bodies 221 are removed and the positions of the front cutter body 221 and the rear cutter body 221 are replaced, and thus the rear cutter body 221 can be fully utilized to fully utilize the crushing cutter 22.

In the present embodiment, each cutter body 221 is provided with a counter bore 50, and each counter bore 50 is correspondingly provided with a locking screw 40; the rod part of the locking screw 40 passes through the corresponding counter bore 50 and is in threaded connection with the cutter holder 222, and the corresponding cutter body 221 is locked on the cutter holder 222 through the head part of the locking screw 40, so that the cutter body 221 is detachably arranged on the cutter holder 222, and the assembly and disassembly are convenient; the head of the locking screw 40 is disposed within the counterbore 50, reducing the likelihood of the head of the locking screw 40 protruding through the crushing blade 22 and reducing bridging.

The thickness of the cutter body 221 of this embodiment is 77mm along the direction of extension of the counterbore 50, and the thickness of the cutter body 221 is favorable for machining the counterbore 50 which is large enough and deep enough to accommodate the head of the locking screw 40.

The tool holder 222 of the present embodiment is flush with the surface of the tool body 221 facing away from the rotating shaft 21, and at this time, the tool holder 222 does not protrude, and does not generate resistance with the waste, thereby reducing the influence of the resistance on the connection strength of the locking screw 40.

It is worth mentioning that the crushing blade 22 can be mounted by, but not limited to, screws.

Each knife roller 20 of the embodiment comprises a plurality of crushing knives 22, and the crushing knives 22 of each knife roller 20 are arranged at intervals from a position close to one end of the rotating shaft 21 to a position close to the other end of the rotating shaft 21; at this time, the crushing knives 22 are distributed more comprehensively to realize more comprehensive crushing; meanwhile, under the condition that the length of the rotating shaft 21 is determined, if one crushing knife 22 is arranged, the crushing knife 22 is arranged in a long strip shape, the width of the crushing knife 22 in the axial direction of the rotating shaft 21 is too large, the crushing knife 22 crushes waste materials in a large area, and the waste materials are easy to block.

Specifically, the plurality of crushing blades 22 of each knife roll 20 are spirally distributed.

Because the rotating shaft 21 does not rotate due to material blocking in the crushing process, the crushing device further comprises a driving device 30, a detection device and a controller; the driving device 30 is used for driving the two rotating shafts 21 to rotate; the detection device is used for detecting whether the rotating shaft 21 rotates or not; the controller is used for controlling the operation of the driving device 30 according to the detection result of the detection device; in practical application, when the driving device 30 is started to operate, the controller is started; under normal conditions, the driving device 30 drives the two rotating shafts 21 to rotate for crushing operation, wherein the detecting device and the controller can be set as: when the rotating shaft 21 stops rotating, the detection device sends a material blocking signal to the controller when detecting that the rotating shaft 21 is not moved, and the controller controls the driving device 30 to drive the two rotating shafts 21 to rotate reversely when receiving the material blocking signal, so that waste materials blocked between the two rotating shafts 21 can be pushed out, the material blocking is removed, at the moment, the detection device sends an operation signal to the controller when detecting that the rotating shaft 21 normally rotates, and the controller controls the driving device 30 to continuously drive the two rotating shafts 21 to rotate for crushing operation.

The above-mentioned detection device can be used, but not limited to, an existing motion sensor.

The driving device 30 may include a motor and a gear transmission mechanism, the motor drives the two rotating shafts 21 to rotate through the gear transmission mechanism, and at this time, the motor is shared, so that energy consumption is reduced; of course, the driving device 30 may further include two motors, and the two motors respectively drive the two rotating shafts 21 to rotate, so as to achieve independent control, and be capable of independently adjusting the rotation time of each rotating shaft 21, and being flexible in use.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
