[0027] As shown in Figure 2 、 Figure 3 and Figure 4 , the plate hammer assembly is detachably arranged on the wall surface of the rotor 12 for crushing ore, the plate hammer assembly comprises a detachable unit 20, a guide rod 21, an adjusting channel 22, a limiting groove 23 and a limiting protrusion 24, the guide rod 21 is inserted with the rotor 12, the guide rod 21 is provided with a plurality of detachable detachable units 20 along the radial direction, each detachable unit 20 is provided with the same adjusting channel 22, the guide rod 21 is located in the adjusting channel 22, the guide rod 21 can float in the adjusting channel 22, the limiting groove 23 is formed on one side of the detachable unit 20, the limiting protrusion 24 is fixedly installed on the other side of the detachable unit 20, the limiting protrusion 24 can be inserted into the limiting groove 23 of the adjacent other detachable unit 20, a plurality of rectangular insertion grooves are formed on the circumferential surface of the rotor 12, a group of plate hammer assemblies are arranged in each rectangular insertion groove, a plug hole matched with the guide rod 21 is formed on the inner wall surface of the rotor 12, the guide rod 21 is inserted with the plug hole, the detachable unit 20 forms a rectangular block structure, the height of the detachable unit 20 is greater than the depth of the rectangular insertion groove, the guide rod 21 forms a cylindrical structure, the adjusting channel 22 forms a rectangular groove in cross section, the width of the adjusting channel 22 is equal to the diameter of the guide rod 21, the limiting protrusion 24 is integrally formed with the detachable unit 20, the limiting protrusion 24 forms a rectangular rod structure, the limiting groove 23 is a slot with a rectangular cross section, the height of the limiting groove 23 is greater than the height of the limiting protrusion 24, and the limiting protrusion 24 can slide in the limiting groove 23;

[0028] In this solution, a detachable plate hammer assembly is provided, and correspondingly, an inspection window is opened on the front wall of the casing 10, and a cover plate is fixedly installed at the inspection window by bolts. An end plate is installed at the front end of the rotor 12 by bolts, and the end plate presses each guide rod 21 against and against. By plugging a plurality of disassembly units 20 on the guide rod 21, the disassembly unit 20 is pushed into the rectangular slot, and the limiting protrusion 24 is inserted into the limiting groove 23 of another adjacent disassembly unit 20, so that the plurality of disassembly units 20 can contact each other. Since the height of the limiting groove 23 is greater than the height of the limiting protrusion 24, the limiting protrusion 24 can slide vertically in the limiting groove 23, and the rotor During the rotation of 12, multiple disassembly units 20 can be distributed in a staggered manner, but when subjected to lateral shear force, multiple disassembly units 20 can form a whole. Compared with a single independent disassembly unit 20, the extrusion of the rotor 12 by a single disassembly unit 20 can be reduced. Multiple disassembly units 20 squeeze the inner wall of the rotor 12 as a whole, which can reduce the pressure and thereby reduce the probability of local collapse and damage of the rotor 12. The design of the disassembly unit 20 floating in the rectangular groove by the guide rod 21 floating in the adjustment channel 22 can avoid the probability of damage caused by the disassembly unit 20 being stuck with the ore to a certain extent, and has the characteristics of longer service life and easier maintenance.

[0029] like Figure 5 As shown, the plate hammer assembly also includes a horizontal groove 32 and a convex rib 33. The disassembly unit 20 is composed of a hammer part 30 and a root 31. The convex rib 33 is fixedly connected to the hammer part 30. The wall surface of the root 31 is provided with a horizontal groove 32. The convex rib 33 is plugged into the horizontal groove 32. The convex rib 33 forms a rod body with a bow-shaped cross section. The horizontal groove 32 and the convex rib 33 cooperate with each other. As a supplement to the above scheme, by providing a detachable disassembly unit 20, specifically, it is necessary to remove the end plate at the end of the rotor 12, push the disassembly unit 20 to slide along the guide rod 21 and form a certain gap. When a single disassembly unit 20 is located in the middle position on the guide rod 21, When the element 20 needs to be replaced, the hammer part 30 is pushed, and the hammer part 30 drives the rib 33 to slide in the horizontal groove 32, and the hammer part 30 can be removed. Since the root part 31 is located in the rectangular slot, the hammer part 30 protrudes from the rotor 12 to hit the ore, and the end of the hammer part 30 will wear faster. By replacing the hammer part 30 instead of replacing the entire disassembly unit 20, the maintenance cost is lower. Secondly, the staggered plug-in hammer part 30 and the root 31 can conveniently disassemble and assemble the hammer part 30 located in the middle of the guide rod 21. There is no need to remove the entire guide rod 21 and then replace the new disassembly unit 20 and then reinstall the guide rod 21. Maintenance is more convenient and easy to maintain.

[0030] The limiting groove is formed on the wall surface of the root portion 31 , the hammering portion 30 and the root portion 31 jointly form an adjustment channel 22 , and the limiting protrusion 24 is integrally formed with the root portion 31 .

[0031] The utility model discloses a working principle: motor and casing 10 fixed connection, the output shaft of motor is connected with speed reducer, and the output of speed reducer is fixedly connected with rotor 12, and the ore is broken through the rotation of rotor 12, and the rebound of counterattack board is matched, realizes the crushing of ore;

[0032] The front wall of the casing 10 is provided with an inspection window, and the inspection window is provided with a cover plate fixedly installed through bolts. The front end of the rotor 12 is provided with an end plate installed through bolts. The end plate abuts and presses the guide rods 21. A plurality of disassembly units 20 are inserted into the guide rods 21. The disassembly units 20 are pushed into the rectangular insertion slots. The limiting protrusions 24 are inserted into the limiting grooves 23 of the adjacent disassembly units 20. The disassembly units 20 can abut each other. Since the height of the limiting groove 23 is greater than the height of the limiting protrusion 24, the limiting protrusion 24 can vertically slide in the limiting groove 23. During the rotation of the rotor 12, the disassembly units 20 can be distributed in a staggered manner. However, when subjected to lateral shear force, the disassembly units 20 can form a whole. Compared with a single independent disassembly unit 20, the extrusion of the single disassembly unit 20 on the rotor 12 can be reduced. The whole extrusion of the disassembly units 20 on the inner wall of the rotor 12 can reduce the pressure, thereby reducing the probability of local collapse and damage of the rotor 12. The end plate at the end of the rotor 12 needs to be removed. The disassembly units 20 are pushed to slide along the guide rods 21 and form a certain gap. When a single disassembly unit 20 located at the middle position of the guide rod 21 needs to be replaced, the hammering part 30 is pushed. The hammering part 30 drives the protruding ribs 33 to slide in the horizontal groove 32. The hammering part 30 can be removed. Since the root 31 is located in the rectangular insertion slot, the hammering part 30 protrudes from the rotor 12 to hit the ore. The end part of the hammering part 30 will wear out faster. By replacing the hammering part 30 instead of replacing the whole disassembly unit 20, the maintenance cost is lower. Secondly, the staggered insertion of the hammering part 30 and the root 31 can conveniently disassemble the hammering part 30 located at the middle part of the guide rod 21. It is not necessary to remove the whole guide rod 21 and all the disassembly units 20 to replace new disassembly units 20 and then reinstall the guide rod 21.
