Description

Technical Field

[0001] The utility model belongs to the technical field of construction machinery, and particularly relates to a counterattack crusher which is convenient for rotor maintenance. Background Technique

[0002] The counterattack crusher is mainly used for crushing materials. When the device is working, driven by an electric motor, the rotor rotates at a high speed. The material enters the action area of the plate hammer, impacts and breaks with the plate hammer on the rotor, and then is thrown onto the counterattack device for further crushing. Then it bounces back from the counterattack lining plate to the action area of the plate hammer for re-crushing. This process is repeated until the material is crushed to the required particle size.

[0003] Due to the convenience of the counterattack crusher, it is widely used in material processing operations such as metallurgy, chemical industry, building materials, and hydropower that often require relocation. With long-term use of the counterattack crusher, the moment of inertia of the rotor will gradually decrease. When the moment of inertia of the rotor is insufficient, it will affect the operation of the device and the crushing effect, and it is necessary to maintain or replace the rotor components. In the design of the existing device, the internal rotor device is mostly fixed to the rotor frame by welding, that is, the rotor frame, the plate hammer and other vulnerable components are integrally connected to the frame of the device. Therefore, only the whole rotor can be replaced during maintenance, and cutting operations may be required. The maintenance work is time-consuming and laborious, increasing the production cost and reducing the enterprise efficiency. Therefore, it is urgent to improve the structure of the device.

Detailed implementation manners

[0023] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0024] The counter - impact crusher facilitating rotor maintenance provided by the present utility model, as shown in Figure 1As shown in the figure, it includes a housing 1. A feed box 2 is fixedly arranged on the side wall of the housing 1 near the top. A feed inlet is provided on the side of the feed box 2 away from the housing 1, and the feed inlet is horizontally oriented. A ramp for guiding the sliding of materials is arranged in the feed box 2. A rotor mechanism 3 is arranged near the bottom in the housing 1, and the rotor mechanism 3 is arranged at the lower end of the material ramp. After the materials are put in, they are centrally guided by the ramp to the rotor mechanism 3 for crushing operations. One end of the rotor mechanism 3 passes through the housing 1 and is connected to a rotating wheel 5, and the other end is connected to a bearing seat 6. Both the rotating wheel 5 and the bearing seat 6 are arranged outside the housing 1 and correspond to the position where the rotor mechanism 3 is located, and the rotating wheel 5, the bearing seat 6 and the rotor mechanism 3 are coaxial. The rotating wheel 5 can be a pulley or the like, and is driven by a motor to provide rotational force, and cooperates with the bearing seat 6 at the other end to drive the rotor mechanism 3 to rotate along the axis. A number of impact liners are arranged inside the housing 1 around the rotor mechanism 3. The plate surface of the impact liner is parallel to the axial direction of the rotor mechanism 3, and the materials broken and ejected by the rotor mechanism 3 are rebounded back to the rotor for multiple crushing. The number of impact liners can be set according to the angles and distances required for impact. A disassembly mechanism 4 is arranged at the axis of the rotor mechanism 3, and the rotor mechanism 3 can be disassembled through the disassembly mechanism 4 during maintenance.

[0025] Among them, as Figure 2 and Figure 3As shown in the figure, the specific structure of the rotor mechanism 3 includes a rotating shaft 301. One end of the rotating shaft 301 passes through the housing 1 and is key-connected to the rotating wheel 5, and the other end is rotatably connected to the bearing seat 6. The bearing seat 6 can be fixed on the outer surface of the housing 1. Both ends of the rotating shaft 301 extend out of the housing 1 and respectively extend into the axles of the rotating wheel 5 and the bearing seat 6, and are driven by the rotating wheel 5 to rotate relative to the bearing seat 6. A rotor frame 302 is sleeved on the outer surface of the rotating shaft 301 inside the housing 1. A plurality of plate hammers 303 are symmetrically and fixedly arranged around the outer circumference of the rotor frame 302. Slots for installing the plate hammers 303 can be provided on the rotor frame 302. Each plate hammer 303 is arranged in the slot and fixedly connected to the rotor frame 302. A number of clamping blocks 304 are provided at the joint of the rotating shaft 301 and the rotor frame 302, and corresponding clamping grooves for accommodating the clamping blocks 304 are provided on the rotating shaft 301 and the rotor frame 302. The clamping grooves on the rotating shaft 301 and the rotor frame 302 are arranged oppositely and communicated. The clamping blocks 304 are arranged inside the communicated clamping grooves. The rotating shaft 301 is of a hollow structure, and a connecting rod 305 with the same number as the clamping blocks 304 is provided in the central cavity. Each clamping block 304 extends into the cavity through the clamping groove and is hinged to one end of the connecting rod 305. The number of the clamping blocks 304 and the connecting rods 305 can be set as required. For example, the number of both the clamping blocks 304 and the connecting rods 305 is set to 10, and they are evenly and symmetrically distributed on both sides along the axial direction of the rotating shaft 301. Since the connecting rod 305 and the clamping block 304 are hinged, under the action of the disassembly mechanism 4, when the connecting rod 305 moves to one side in the cavity, the clamping block 304 will move along the inner surface of the rotating shaft 301 and towards the inner cavity of the rotating shaft 301 under the drive of the connecting rod 305, so that the clamping block 304 is separated from the rotor frame 302, and the locking of the position of the rotor frame 302 by the clamping block 304 is released, and thus the disassembly of the rotor frame 302 can be realized. When the connecting rod 305 is reset, a part of the clamping block 304 extends into the clamping groove on the rotor frame 302, locking the relative positions of the rotating shaft 301 and the rotor frame 302, so that it is not necessary to weld the rotor frame 302 and the rotating shaft 301, which is convenient for maintaining the rotor.

[0026] In the above structure, as Figure 3 and Figure 4 shown, the disassembly mechanism 4 specifically includes a threaded rod 401. The threaded rod 401 passes through the central cavity of the rotating shaft 301. A plurality of connecting blocks 402 are sleeved on the threaded rod 401 in the cavity. The connecting blocks 402 can be rectangular blocks with internal threads, and are arranged corresponding to the connecting rods 305. One end of the connecting rod 305 except the end hinged to the clamping block 304 is hinged to the end face of the corresponding connecting block 402. One end of the threaded rod 401 is fixedly connected to a first handle 403. When the first handle 403 is rotated, the threaded rod 401 will rotate, so that the connecting block 402 threadedly sleeved on the threaded rod 401 drives one side of the connecting rod 305 to move. When the first handle 403 is rotated in the reverse direction, the threaded rod 401, the connecting block 402 and the connecting rod 305 are reset.

[0027] In addition, as shown in Figure 5 and Figure 6 To ensure that the rotating wheel 5 does not rotate relative to the rotor during disassembly and to ensure the stable and safe operation, a support block 8 is fixedly arranged on the outer wall of the housing 1 near the rotating wheel 5. A round rod 9 penetrates through the support block 8. The inner surface of the support block 8 and the outer surface of the round rod 9 are both smooth, enabling the round rod 9 to slide inside the support block 8 towards the direction of the rotating wheel 5. A limit block 13 is provided at one end of the round rod 9 close to the rotating wheel 5, and a second handle 11 is fixedly connected to the other end. A limit groove 7 is correspondingly arranged on the rotating wheel 5. A connecting spring 12 is sleeved on the round rod 9 inside the support block 8. A baffle 10 is fixedly connected to the side of the connecting spring 12 away from the rotating wheel 5, and the baffle 10 is fixedly sleeved on the round rod 9. The connecting spring 12 is in a stretched state. Under the restoring action of the connecting spring 12, the baffle 10 will drive the round rod 9 and the limit block 13 to move towards the rotating wheel 5, causing the limit block 13 to be embedded inside the limit groove 7, thus realizing the locking of the rotating wheel 5. A clamping hole is provided on the rod body of the round rod 9, and the position of the clamping hole is between the baffle 10 and the second handle 11, that is, the part of the round rod 9 extending out of the support block 8, generally arranged near the support block 8. A clamping rod 14 is arranged in the clamping hole. A fixing plate 15 is fixedly arranged on the top of the support block 8. One end of the clamping rod 14 has a slightly thicker outer diameter. When the clamping rod 14 is inserted into the clamping hole, the part with a thicker outer diameter of the clamping rod 14 is placed above the fixing plate 15. The clamping rod 14 passes through and is movably sleeved and engaged with the fixing plate 15, realizing the blocking of the round rod 9 and keeping the connecting spring 12 in a stretched state. When the clamping rod 14 is pulled out to separate it from the round rod 9, the blocking will be released and the connecting spring 12 will contract.

[0028] In the above structure, the impact liner can be designed into two pieces, as shown in Figure 2 Specifically, it includes a first impact liner 17 and a second impact liner 20. The first impact liner 17 is movably connected to the housing 1 through a first fixing rod 16 inserted from the side. The plate surface of the first impact liner 17 facing away from the rotor mechanism 3 is elastically connected to the side wall of the housing 1 through a first spring 18; the second impact liner 20 is movably connected to the housing 1 through a second fixing rod 19 inserted from the side. The plate surface of the second impact liner 20 facing away from the rotor mechanism 3 is elastically connected to the top wall of the housing 1 through a second spring 21. When the two impact liners are impacted, they will vibrate slightly around the fixing rod and quickly reset under the action of the spring, thereby alleviating the impact force received and prolonging the service life of the components.

[0029] The working principle and maintenance process of the device provided by the present utility model are as follows:

[0030] When using this device to crush materials, the rotating wheel 5 drives the rotating shaft 301 to rotate through the motor. The materials are poured into the interior of the housing 1 through the feed hopper 2. Under the action of the plate hammers 303, the first impact lining plate 17 and the second impact lining plate 20, the materials are repeatedly impacted and crushed to the required particle size. When the moment of inertia is insufficient and the rotor needs to be maintained and replaced, first pull the clamping rod 14 to separate the clamping rod 14 from the round rod 9, releasing the blockage of the clamping rod 14 on the round rod 9. Since the connecting spring 12 is in a stretched state, under the restoring action of the connecting spring 12, the baffle 10 will drive the round rod 9 and the limit block 13 to slide towards the rotating wheel 5 until the limit block 13 is inserted into the limit groove 7, thereby fixing the rotating wheel 5. Then, by rotating the first handle 403, the threaded rod 401 rotates. At this time, the connecting block 402 threadedly sleeved on the threaded rod 401 will drive the connecting rod 305 to move laterally, so that the connecting rod 305 generates a pulling force on the clamping block 304, pulling the clamping block 304 towards the center position of the rotating shaft 301, thereby releasing the locking of the position of the rotor frame 302 by the clamping block 304, and thus enabling the rapid disassembly of the rotor frame 302 for easy replacement and maintenance.
