[0016] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:
[0017] In the present invention, the first motor 15, the second motor 14-4, the hydraulic pump 2 and the hydraulic cylinder 8 are all connected to the external electric control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.
[0018] According to the instruction manual Figure 1 It can be known that when the utility model is in use, the driving member drives the connected driving shaft 10 to rotate. The driving member can be a pulley or a coupling that is transmitted through a driving motor, or directly a driving motor. The driving member is a variable frequency motor or uses a variable frequency motor as a driving source. The operator can reasonably adjust the speed of the driving motor according to the actual use environment. The driving member drives the driving shaft 10 to rotate, and the driving shaft 10 drives the first driving gear 9 set at the end to rotate. The first driving gear 9 drives the meshing transmission gear 12 to rotate, and the transmission gear 12 drives the eccentric sleeve 5 to rotate, and the eccentric sleeve 5 drives the movable cone 6 to rotate. The movable cone 6 is arranged on the top of the eccentric shaft 4 through the existing support assembly. The hydraulic pump 2 can adjust the height of the movable cone 6 through the eccentric shaft 4, so that when there is a metal foreign body between the movable cone 6 and the fixed cone 7, the movable cone 6 can be moved downward to expand the gap and make the metal foreign body fall out; by adding materials into the adjustment sleeve 14, the materials are buffered by the buffer assembly and then fall between the movable cone 6 and the fixed cone 7. The buffered materials can prevent the surfaces of the movable cone 6 and the fixed cone 7 from being damaged when falling, thereby extending the service life of the equipment. The rotation of the movable cone 6 can effectively prevent the foreign body from falling. When the first motor 15 on the first support sleeve 18 is started, the output end of the first motor 15 drives the connected second driving gear 11 to rotate, the second driving gear 11 drives the meshing connected external gear 19-1 to rotate, and the external gear 19-1 drives the second support sleeve 19 to rotate. Since the second tooth groove 17 provided on the second support sleeve 19 is meshingly connected with the first tooth groove 16 provided on the first support sleeve 18, the first support sleeve 18 is fixedly arranged on the frame 1, so the second support sleeve 19 can drive the fixed cone 7 to move in the vertical direction, which can be connected with the device A plurality of hydraulic cylinders 8 disposed on the frame 1 are used in combination or separately to adjust the vertical height of the fixed cone 7. The combined use further expands the moving range of the fixed cone 7. The utility model adjusts the vertical height of the eccentric shaft 4 and the movable cone 6 through the hydraulic pump 2, thereby adjusting the compression amount between the movable cone 6 and the fixed cone 7. When there is a metallic foreign body between the movable cone 6 and the fixed cone 7, the gap between them can be expanded to allow the foreign body to fall out. In addition, the buffer assembly on the adjustment sleeve 14 can reduce the damage to the equipment caused by the material falling directly onto the movable cone 6 and the fixed cone 7, thereby extending the service life of the equipment.
[0019] There is a possibility of implementation. When conveying materials into the adjustment sleeve 14, the umbrella-shaped guide plate 14-2 guides the materials to all sides, and the materials fall onto the multiple arc-shaped guide plates 14-5 on the upper layer. One end of the arc-shaped guide plate 14-5 is hinged to the inner wall of the adjustment sleeve 14, and the buffer spring 14-6 arranged therebetween can enable the arc-shaped guide plate 14-5 to buffer the materials. The second motor 14-4 arranged in the connecting tube 14-3 drives the material-dispensing plate 14-7 to rotate, and the material-dispensing plate 14-7 guides the materials to the arc-shaped guide plate 14-5 on the lower layer. When the buffered materials enter the crushing chamber between the moving cone 6 and the fixed cone 7, the collision with the surfaces of the moving cone 6 and the fixed cone 7 can be reduced, thereby extending the service life of the equipment. The output end of the second motor 14-4 is connected to the material-dispensing plate 14-7 through a connecting rod. A limiting ring is arranged on the connecting rod and on the bottom wall of the connecting tube 14-3. The limiting ring can limit the connecting rod to prevent the connecting rod from moving vertically downward.
[0020] In one possible implementation, the arc-shaped material guide plate 14 - 5 is tilted downward at a certain angle so that the arc-shaped material guide plate 14 - 5 has a better buffering effect.
[0021] There is a possibility of implementation, the material stripping plate 14-7 is tilted and eccentrically arranged on the output end of the second motor 14-4, so that the material dropped from the upper arc-shaped material guide plate 14-5 can fall onto the lower arc-shaped material guide plate 14-5 again.
[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
