Description

Technical Field

[0001] This utility model relates to the field of crushing roller installation technology, specifically to a crushing roller for a crusher. Background Technology

[0002] Crushing rollers are an indispensable structure in roller crushers. They crush materials by driving two crushing rollers to rotate relative to each other. In order to ensure the crushing efficiency and safety of the crushing rollers, they need to be inspected and maintained regularly.

[0003] The existing methods for fixing crushing rollers are mostly bolt connections or welding. However, after long-term use, some bolts may deform, making them difficult to remove. Welding fixation is also inconvenient for disassembly. Neither of these methods is conducive to the rapid replacement of crushing rollers, thereby reducing the maintenance efficiency of crushing rollers and causing certain inconveniences. Utility Model Content

[0004] In view of this, the present invention provides a crushing roller for a crusher, which allows for quick disassembly and assembly, thereby improving the maintenance efficiency of the crushing roller and making the disassembly and maintenance of the crushing roller more convenient.

[0005] To solve the above-mentioned technical problems, this utility model provides a crushing roller for a crusher, including a crushing roller and a crushing box. The inner wall of the crushing box is provided with several mounting frames. Fixed columns are provided at both ends of the crushing roller, and the fixed columns are slidably disposed within the mounting frames. Limit grooves are formed in the inner wall of the mounting frames. Limit blocks are provided on both sides of the fixed columns, and the limit blocks are located within the limit grooves. A positioning groove is formed on one side of the surface of the limit blocks. A quick-release mechanism is provided within the mounting frames. The quick-release mechanism includes an elastic element and a positioning column. The elastic element is used to push the positioning column into the positioning groove. Workers can use the elastic element to push the positioning column into the positioning groove. Since the positioning column cannot slide along the limit groove, the crushing roller can be quickly disassembled and assembled, thereby improving the maintenance efficiency of the crushing roller and making the disassembly and maintenance of the crushing roller more convenient.

[0006] The elastic element includes a mounting groove within the mounting frame, a spring inside the mounting groove, a push plate at one end of the spring, and the push plate slidingly within the mounting groove. A positioning post is fixed to one side wall of the push plate and is snapped into the positioning groove of the limiting block. The upper surface of the positioning post is inclined. When the limiting block is fully inserted into the bottom of the limiting groove, the positioning post corresponds exactly to the opening of the positioning groove, giving the spring a certain amount of rebound space. The rebound force of the spring pushes the positioning post and the push plate to reset, causing the positioning post to move towards the positioning groove, thereby inserting the positioning post into the positioning groove to limit the limiting block and the fixing post, and thus install and fix the crushing roller.

[0007] The inner wall of the mounting trough has a through groove, and a connecting block is slidably installed in the through groove. One end of the connecting block is fixed to the side wall of the push plate, and the other end of the connecting block is equipped with a handle. When the worker pulls the handle, the limit block is released. Then the worker lifts the crushing roller, so that the fixing column slides out from the opening of the mounting frame, thereby completing the disassembly of the crushing roller.

[0008] The handle has a through hole in the center that fits the connecting block. The connecting block is installed through the through hole in the handle. A slot is provided on one side of the through slot. The handle is inserted into the slot to fix the positioning block in the designated position and prevent the spring from rebounding. After the crushing roller is removed, the handle is pulled out of the slot. The spring then pushes the handle and positioning post back to their original positions through the rebound force, making it convenient for the next installation.

[0009] A through hole is provided on the upper part of one inner side wall of the mounting frame, and a limit rod is installed through the through hole. Pushing the limit rod causes it to pass through the through hole on the surface of the mounting frame and gradually insert into the opening of the mounting frame to block the fixing post, thereby preventing the fixing post from shifting position and falling out of the mounting frame.

[0010] Each mounting frame has a rotating column fixed at its end, and the rotating column is rotatably mounted on the side wall of the crushing box. A driving component is provided on one outer side wall of the mounting frame to drive the rotating column to rotate. The rotating column is driven to rotate, and the mounting frame rotates when the rotating column rotates. Since the limiting block is fixed in the limiting groove by the positioning column, the mounting frame rotates while driving the limiting block and the fixed column to rotate synchronously, thereby driving the crushing roller to rotate.

[0011] The driving component includes a drive box mounted on an outer wall of the mounting frame. Inside the drive box, two meshing gears are rotatably mounted, with one end of each gear fixed to the end of a rotating column. A motor is mounted on one side of the outer wall of the drive box, and the output end of the motor is connected to the center of the end of one of the gears. When the operator starts the motor, the output end of the motor drives one of the gears to rotate. Since the two gears mesh with each other, they can drive both gears to rotate simultaneously, thereby driving the rotating column to rotate.

[0012] The crushing box is equipped with a top cover, which is connected to the crushing box by bolts. The workers can remove the top cover to disassemble and assemble the crushing rollers, which is convenient and quick.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. When using this utility model, the operator can push the positioning pin into the positioning groove through the elastic element. Since the positioning pin cannot slide along the limiting groove, the crushing roller can be quickly disassembled and assembled, thereby improving the maintenance efficiency of the crushing roller and making the disassembly and maintenance of the crushing roller more convenient.

[0015] 2. When this utility model is used, after the limiting block is fully inserted into the bottom of the limiting groove, the positioning post is exactly corresponding to the opening position of the positioning groove, so that the spring has a certain rebound space. The rebound force of the spring pushes the positioning post and the push plate to reset, so that the positioning post moves towards the positioning groove, thereby allowing the positioning post to be inserted into the positioning groove to limit the limiting block and the fixing post, and then to install and fix the crushing roller.

[0016] 3. When using this utility model, the operator pulls the handle to release the limit block, and then lifts the crushing roller so that the fixing column slides out from the opening of the mounting frame, thereby completing the disassembly of the crushing roller.

[0017] 4. When using this utility model, push the limiting rod so that it passes through the through hole on the surface of the mounting frame and gradually inserts into the opening of the mounting frame to block the fixing post, thereby preventing the fixing post from shifting position and falling out of the mounting frame.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-8 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] According to one embodiment of the present invention, such as Figure 1-8As shown: This embodiment provides a crushing roller for a crusher, including a crushing roller and a crushing box 100. There are two crushing rollers, both installed inside the crushing box 100. The inner wall of the crushing box 100 has four mounting frames 400. The mounting frames 400 have a U-shaped cross-section and an opening at the top. Fixed posts 301 are provided at both ends of the crushing roller, and each fixed post 301 is slidably disposed within its corresponding mounting frame 400. The operator can slide the fixed post 301 at the end of the crushing roller into the opening of the mounting frame 400, thereby installing the fixed post 301 within the mounting frame 400. A limiting groove 409 is provided on the inner wall of the mounting frame 400. Limiting blocks 302 are provided on both sides of the mounting frame 400, and the limiting blocks 302 are located in the limiting grooves 409. When the worker slides the fixing post 301 into the mounting frame 400 through the opening, the limiting blocks 302 need to be slid down together with the corresponding positions of the limiting grooves 409, so that the limiting blocks 302 can be locked into the bottom of the limiting grooves 409. A positioning groove 303 is provided on the surface of the limiting block 302 and the side that is in contact with the inner wall of the limiting grooves 409. A quick-release mechanism is provided in the mounting frame 400. The quick-release mechanism includes an elastic element and a positioning post 404. The elastic element is used to push the positioning post 404 into the positioning groove 303. When the worker installs the fixing post 301 into the mounting frame 400, and the limiting blocks 302 are locked in place... After being inserted into the bottom of the limiting groove 409, since the fixing post 301 and the limiting block 302 are not yet limited, the limiting block 302 can still slide freely within the limiting groove 409, and the fixing post 301 is not in a fixed state. At this time, the worker can use the elastic element to push the positioning post 404 into the positioning groove 303. Since the positioning post 404 cannot slide along the limiting groove 409, the positioning post 404, when engaged within the limiting groove 409, can limit the limiting block 302, thus fixing the limiting block 302 within the limiting groove 409. Simultaneously, the fixing post 301 and the limiting block 302 are also limited, thereby fixing the fixing post 301 and the mounting frame 400 together, thus preventing damage. The crushing roller is installed inside the crushing box 100. If the crushing roller needs to be removed, the operator uses the elastic element to drive the positioning column 404 out of the positioning groove 303 of the limiting block 302, thereby canceling the limitation of the limiting block 302. This allows the limiting block 302 to slide along the limiting groove 409, thereby canceling the limitation of the fixing column 301. At this time, the operator can lift the crushing roller to make the fixing column 301 slide out from the opening of the mounting frame 400, and the limiting block 302 disengage from the inside of the limiting groove 409, thus completing the disassembly of the crushing roller. Therefore, this device only requires the elastic element and the positioning column 404 to cooperate with each other to quickly disassemble and assemble the crushing roller, improving the maintenance efficiency of the crushing roller and making the disassembly and maintenance of the crushing roller more convenient.

[0029] according to Figure 5 , Figure 7 and Figure 8 As shown, the elastic element includes a mounting groove 401 within the mounting frame 400. Two springs 402 are installed inside the mounting groove 401. A push plate 403 is attached to one end of each spring 402, and the push plate 403 is slidably disposed within the mounting groove 401. A positioning post 404 is fixed to one side wall of the push plate 403. A through hole is provided on the inner wall of the mounting groove 401, corresponding to the position of the positioning post 404. The positioning post 404 penetrates the through hole in the inner wall of the mounting groove 401 and extends into the limiting groove 409. After the crushing roller is installed, for example... Figure 8 As shown, the positioning post 404 is snapped into the positioning groove 303 of the limiting block 302. The upper surface of the positioning post 404, and the direction of its position at the opening of the mounting frame 400, is set as an inclined plane. When the operator needs to install the crushing roller, the fixing post 301 at the end of the crushing roller is slid in through the opening of the mounting frame 400. At the same time, the limiting block 302 slides into the limiting groove 409. When the limiting block 302 slides into the limiting groove 409, the bottom of the limiting block 302 will abut against the inclined surface of the positioning post 404. As the limiting block 302 continues to slide down, it will push the positioning post 404 towards the interior of the mounting groove 401, so that the positioning post 404 will drive the push plate 403 to compress the spring 402. After the 02 fully enters the bottom of the limiting groove 409, the positioning post 404 corresponds exactly to the opening position of the positioning groove 303, so that the spring 402 has a certain rebound space. The rebound force of the spring 402 pushes the positioning post 404 and the push plate 403 to reset, so that the positioning post 404 moves towards the positioning groove 303, thereby allowing the positioning post 404 to be inserted into the positioning groove 303. Since the positioning post 404 can only slide along the placement groove 401 and cannot slide along the limiting groove 409, when the positioning post 404 is inserted into the positioning groove 303, it can limit the limiting block 302, so that the limiting block 302 cannot slide along the limiting groove 409, thereby limiting and fixing the fixing post 301, thus enabling the crushing roller to be installed quickly.

[0030] according to Figure 4 and Figure 5As shown, the inner wall of the mounting groove 401 is provided with a through groove 405. A connecting block 406 is slidably arranged in the through groove 405. One end of the connecting block 406 is fixed to the side wall of the push plate 403, and the other end of the connecting block 406 is equipped with a handle 407. When it is necessary to disassemble the crushing roller, the operator pulls the handle 407. The handle 407 drives the connecting block 406 to slide in the groove. At the same time, the moving of the connecting block 406 drives the push plate 403 to move synchronously. The push plate 403 compresses the spring 402, and the push plate 403 drives the positioning column 404 to move synchronously, so that the positioning column 404 is disengaged from the positioning groove 303, thereby canceling the limitation of the limiting block 302. Then the operator lifts the crushing roller, so that the fixing column 301 slides out from the opening of the mounting frame 400, thereby completing the disassembly of the crushing roller.

[0031] according to Figure 4 As shown, the handle 407 has a through hole in the center that fits the connecting block 406. The connecting block 406 is installed through the through hole of the handle 407. A slot 408 is provided on one side of the surface of the through groove 405, and the slot 408 is located on the side away from the limiting groove 409. When it is necessary to disassemble the crushing roller, the operator pulls the handle 407 to release the limiting block 302, slides the handle 407 to the position corresponding to the slot 408, and then pushes the handle 407 along the surface of the connecting block 406 into the slot 408, so that the handle 407 is engaged in the sliding groove, thereby fixing the positioning block in the designated position and preventing the spring 402 from rebounding. After the crushing roller is removed, the handle 407 is finally pulled out from the slot 408, and the spring 402 pushes the handle 407 and the positioning post 404 to reset by the rebound force, which is convenient for the next installation.

[0032] according to Figure 4 and Figure 5 As shown, a through hole is provided on the upper part of one inner side wall of the mounting frame 400, and a limit rod 500 is installed through the through hole. Damping washers are provided at the contact points between the surface of the limit rod 500 and the through hole, as well as on the inner ring of the through hole. After the crushing roller is installed, the limit rod 500 is pushed so that it passes through the through hole on the surface of the mounting frame 400 and gradually inserts into the opening of the mounting frame 400 to block the fixing post 301, thereby preventing the fixing post 301 from shifting position and falling out of the mounting frame 400. In addition, the limit rod 500 is made of alloy structural steel, which has higher strength and can withstand stronger pressure, preventing damage to the limit rod 500. The damping washers can improve the tightness of the fit between the limit rod 500 and the through hole, preventing the limit rod 500 from falling out of the through hole.

[0033] According to another embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, each mounting frame 400 has a rotating column fixed at its end, and each rotating column is rotatably mounted on the side wall of the crushing box 100. A driving component is provided on one outer side wall of the mounting frame 400. The driving component is used to drive the two rotating columns located on one side wall of the crushing box 100 to rotate. When the operator needs to drive the crushing roller to rotate, the rotating column is driven to rotate through the driving component. When the rotating column rotates, the mounting frame 400 rotates. Since the limiting block 302 is fixed in the limiting groove 409 by the positioning column 404, the mounting frame 400 will drive the limiting block 302 and the fixed column 301 to rotate synchronously while rotating, thereby driving the crushing roller to rotate.

[0034] according to Figure 6 and Figure 7 As shown, the driving component includes a drive box 200 mounted on an outer side wall of the mounting frame 400. Inside the drive box 200, two meshing gears 201 are rotatably mounted, with one end of each gear 201 fixed to the end of a rotating column. A motor 202 is mounted on one side of the outer wall of the drive box 200. The output end of the motor 202 is connected to the center of the end of one of the gears 201. When the operator starts the motor 202, the output end of the motor 202 drives one of the gears 201 to rotate. Since the two gears 201 mesh with each other, they can drive both gears 201 to rotate simultaneously, thereby driving the rotating column to rotate.

[0035] according to Figure 1 As shown, a top cover 101 is installed on the upper part of the crushing box 100. The top cover 101 is connected to the crushing box 100 by bolts. The operator can remove the top cover 101 to disassemble and assemble the crushing roller, which is convenient and quick.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
