[0027] The smashing mechanism 4 comprises an eccentric column 41, a partition plate frame 42, a smashing impact hammer 43 and a driving rotating shaft 44. The driving rotating shaft 44 is rotatably connected between the front and rear inner walls of the smashing shell 3 on the right side. The outer arc surface of the driving rotating shaft 44 is provided with the eccentric column 41. The outer arc surface of the eccentric column 41 is provided with the partition plate frame 42. The smashing impact hammer 43 comprises a smashing rotating shaft 431, a triangular disc 432 and a hammer 433. The smashing rotating shaft 431 is uniformly rotatably connected to the inside of the partition plate frame 42. The outer arc surface of the smashing rotating shaft 431 is fixedly connected with the triangular disc 432 respectively. The triangular ends of the triangular disc 432 are respectively provided with the hammers 433. The smashing mechanism 4 further comprises a rotating rod 45 and an eccentric impact disc 46. The rotating rod 45 is rotatably connected between the front and rear inner walls of the smashing shell 3 on the left side. The outer arc surface of the rotating rod 45 is provided with the eccentric impact discs 46 which are uniformly distributed. The hammers 433 and the eccentric impact discs 46 are staggered and distributed to avoid mutual impact. The smashing mechanism 4 further comprises a wave plate 47 which is arranged on the left upper inner arc surface of the smashing shell 3. The driving mechanism 5 comprises a multi-groove driving wheel 51, a motor 52, a first driving wheel 53 and a second driving wheel 54. The first driving wheel 53 is arranged on the front end of the rotating rod 45. The front end of the driving rotating shaft 44 is provided with the second driving wheel 54. The left side of the rack 1 is provided with the motor 52. The output shaft of the motor 52 is provided with the multi-groove driving wheel 51. The first driving wheel 53 and the second driving wheel 54 are respectively in transmission connection with one multi-groove driving wheel 51 through a transmission belt. The input end of the motor 52 is electrically connected with the output end of the control switch 6. The right upper side of the rack 1 is provided with the feeding shell 2. The upper side between the front and rear inner walls of the feeding shell 2 is hingedly connected with a push plate 7 through a pin shaft. The right lower side arc surface of the push plate 7 is in contact with the outer arc surface of the eccentric column 41. The left side of the push plate 7 is in staggered distribution with the partition plate frame 42. Then the control switch 6 can be adjusted and controlled. The motor 52 operates. The output shaft of the motor 52 rotates, thereby driving the multi-groove driving wheel 51 to rotate, thereby driving the first driving wheel 53 and the second driving wheel 54 to rotate simultaneously through the transmission belt. It is worth noting that the diameters of the first driving wheel 53 and the second driving wheel 54 are not the same, so the rotating speed of the driving rotating shaft 44 and the rotating speed of the rotating rod 45 are not the same. The rotating speed of the rotating rod 45 is greater than the rotating speed of the driving rotating shaft 44. In the process of rotating the driving rotating shaft 44, the eccentric column 41 rotates around the central axis of the driving rotating shaft 44. When the far end of the eccentric column 41 rotates to the uppermost side, the push plate 7 moves. The push plate 7 rotates clockwise around the pin shaft by a specified angle. When the far end of the eccentric column 41 rotates to the lowermost side, the push plate 7 rotates counterclockwise around the pin shaft by a specified angle. Then the push plate 7 reciprocatingly pushes up and down with the continuous rotation of the eccentric column 41. At this time, the concrete raw materials can be put into the inside of the feeding shell 2. If the diameter of the concrete raw materials is larger, the push plate 7 reciprocatingly pushes up and down and cooperates with the inner side wall of the feeding shell 2 to smash the larger particles for the first time. If the larger particles cannot be smashed by one-time extrusion, they will stay between the push plate 7 and the inner side wall of the feeding shell 2.Then by the multiple poking of the poking plate 7, it will be broken, wherein the holes on the poking plate 7 will directly sieve the smaller particles and drop them into the frame 1, the larger particles of the concrete raw material stone will be broken for the first time, and then fall on the eccentric column 41, at this time, the high-speed rotating eccentric column 41 will drive the hammer 433 on the smashing hammer 43 to hit the concrete raw material stone at high speed, forcing the surface of the concrete raw material stone to accept the bite and hit, and breaking it, if the concrete raw material stone here is still large, the high-speed rotating eccentric impact disc 46 on the rotating rod 45 will also clamp the impact concrete raw material, and the clamped impact concrete raw material will be bounced on the wave plate 47 and broken, and then naturally falls and is again impacted and smashed by the eccentric impact disc 46, and then discharged along the guide plate 8 to the outside of the device.

[0028] The working principle of the concrete raw material pulverizer is as follows: when the pulverizer is used, the pulverizer can be placed on the specified work station through the support, then the control switch 6 can be adjusted and controlled, the motor 52 is operated, the output shaft of the motor 52 rotates, and then the multi-groove driving wheel 51 is driven to rotate, and then the first driving wheel 53 and the second driving wheel 54 are simultaneously driven to rotate through the transmission belt, it is worth noting that the diameters of the first driving wheel 53 and the second driving wheel 54 are not the same, so the rotating speed of the driving rotating shaft 44 is not the same as the rotating speed of the rotating rod 45, and the rotating speed of the rotating rod 45 is greater than the rotating speed of the driving rotating shaft 44, in the process of rotating the driving rotating shaft 44, the eccentric column 41 will rotate around the central axis of the driving rotating shaft 44, when the far end of the eccentric column 41 rotates to the uppermost side, the push plate 7 will be moved, the push plate 7 will rotate around the pin shaft by a specified angle clockwise, when the far end of the eccentric column 41 rotates to the lowermost side, the push plate 7 will rotate around the pin shaft by a specified angle counterclockwise, then the push plate 7 is driven to reciprocate up and down with the continuous rotation of the eccentric column 41, at this time, the concrete raw material can be put into the inside of the feeding shell 2, if the diameter of the concrete raw material is relatively large, the concrete raw material will be reciprocated up and down by the push plate 7 and the inside wall of the feeding shell 2 to break the relatively large stone particles for the first time, if the stone particles cannot be broken by one-time extrusion, the stone particles will stay between the push plate 7 and the inside wall of the feeding shell 2, and then the stone particles will be broken by the push plate 7, in the process of reciprocating up and down of the push plate 7, the leakage hole of the push plate 7 will directly screen the smaller particles and drop in the rack 1, after the relatively large concrete raw material stone particles are broken for the first time, the diameter of the concrete raw material stone particles will be greatly reduced, and then the concrete raw material stone particles fall on the eccentric column 41, at this time, the eccentric column 41 rotates at high speed and drives the hammer 433 on the pulverizing impact hammer 43 to impact the concrete raw material stone particles at high speed, so that the surface of the concrete raw material stone particles is bitten and hit, and the concrete raw material stone particles are broken, if the concrete raw material stone particles are still relatively large, the eccentric impact disc 46 rotating at high speed on the rotating rod 45 will also impact the concrete raw material, the impacted concrete raw material will be bounced on the wave plate 47 and broken, and then naturally falls and is impacted and broken by the eccentric impact disc 46 again, and then the concrete raw material is discharged to the outside of the device along the guide plate 8.

[0029] It is worth noting that the motor 52 disclosed in the above embodiment can be freely configured according to the actual application scene, and the motor 52 is recommended to be a YL90L-2 type pulverizing motor, and the control switch 6 is provided with a control button corresponding to the motor 52 and used for controlling the switch of the motor 52.
