It is widely used in mining, building materials, metallurgy, chemical and other industries, and is suitable for crushing materials with medium hardness and below, such as coal, limestone, gypsum and coke.

[0003] In existing technology, during the use of roller crushers, wear-resistant roller sleeves are installed on the rollers for auxiliary crushing to improve the service life of the rollers. However, to ensure subsequent performance, the roller sleeves have tight connections and limited space for disassembly, making subsequent installation and disassembly difficult. Therefore, this invention designs a wear-resistant roller sleeve structure for roller crushers. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the use of roller crushers, in order to improve the service life of the roller body, it is necessary to install wear-resistant roller sleeves on the roller body for auxiliary crushing. However, in order to ensure the subsequent use effect, the connection of the roller sleeve is relatively tight and the reserved disassembly space is small, which leads to the problem that subsequent installation and disassembly are relatively laborious. Therefore, a wear-resistant roller sleeve structure for roller crushers is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wear-resistant roller sleeve structure for a roller crusher includes a roller body, a first roller sleeve, and a second roller sleeve. The first and second roller sleeves are respectively sleeved on the roller wall of the roller body, and their side walls are fitted together. The roller body has an internal cavity. A rotating shaft is rotatably connected to the inner wall of the roller body within the cavity. A first bevel gear is fixedly connected to one end of the rotating shaft inside the roller body. A fixing plate is fixedly connected to the inside of the roller body within the cavity. A screw is rotatably connected to the inside of the fixing plate.

Slots are respectively opened on both sides of the roller body. Insert blocks are fixedly connected to the inner walls of the first and second roller sleeves, and the insert blocks are inserted into the inner walls of the slots. A clamping mechanism is provided inside the roller body.

[0007] Preferably, the clamping mechanism includes a fixed rod, a clamping plate, and a torsion spring. The roller body has a rectangular groove on the inner wall of the slot. The fixed rod is fixedly connected to the inner wall of the rectangular groove. The clamping plate and the torsion spring are sleeved on the rod wall of the fixed rod. The inner wall of the insert block has a clamping groove. The clamping plate is clamped to the inner wall of the clamping groove.

[0008] Preferably, one end of the torsion spring is fixedly connected to the inner wall of the card plate, and the other end of the torsion spring is fixedly connected to the inner wall of the roller.

[0009] Preferably, a sealing gasket is fixedly connected to the end of the card plate, and the sealing gasket is pressed tightly onto the inner wall of the insertion block located in the card slot.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Reference Figure 1-3 A wear-resistant roller sleeve structure for a roller crusher includes a roller body 1, a first roller sleeve 2, and a second roller sleeve 3. The first roller sleeve 2 and the second roller sleeve 3 are respectively sleeved on the roller wall of the roller body 1. The side walls of the first roller sleeve 2 and the second roller sleeve 3 are fitted together. A cavity is opened inside the roller body 1. A rotating shaft 4 is rotatably connected to the inner wall of the roller body 1 in the cavity. A first bevel gear 5 is fixedly connected to one end of the rotating shaft 4 inside the roller body 1. A fixing plate 6 is fixedly connected to the inside of the fixing plate 6. A screw 7 is rotatably connected to the inside of the fixing plate 6. A second bevel gear 8 is fixedly connected to one end of the screw 7 inside the cavity. The first bevel gear 5 and the second bevel gear 8 are meshed with each other. Slots are opened on both sides of the roller body 1. Insert blocks 9 are fixedly connected to the inner walls of the first roller sleeve 2 and the second roller sleeve 3 respectively. The insert blocks 9 are inserted into the inner walls of the slots.

[0022] The roller body 1 is provided with a clamping mechanism inside. The clamping mechanism includes a fixed rod 10, a clamping plate 11 and a torsion spring 12. The inner wall of the roller body 1 is provided with a rectangular groove. The fixed rod 10 is fixedly connected to the inner wall of the rectangular groove. The clamping plate 11 and the torsion spring 12 are sleeved on the rod wall of the fixed rod 10. The inner wall of the insert block 9 is provided with a clamping groove. The clamping plate 11 is clamped and set in the inner wall of the clamping groove.

[0023] One end of the torsion spring 12 is fixedly connected to the inner wall of the clamping plate 11, and the other end of the torsion spring 12 is fixedly connected to the inner wall of the roller body 1. A sealing gasket 13 is fixedly connected to the end of the clamping plate 11. The sealing gasket 13 is pressed and set on the inner wall of the insert block 9 located in the slot. A slider 14 is threadedly connected to the rod wall of the screw 7. A fixing sleeve 15 is fixedly connected to the side wall of the slider 14. A connecting seat 16 is slidably provided on the inner wall of the fixing sleeve 15. A movable block 17 is hinged on the side of the connecting seat 16 away from the fixing sleeve 15. A movable groove is opened on the inner wall of the clamping plate 11. The movable block 17 is slidably set on the inner wall of the movable groove.

[0024] Roller 1 is the core rotating component of the crusher. It is fitted with a first roller sleeve 2 and a second roller sleeve 3 on the outside. The side walls of the two roller sleeves fit together to form a crushing working surface that contacts the material. The first roller sleeve 2 and the second roller sleeve 3 are made of high-hardness wear-resistant material and come into direct contact with materials such as ore and stone. They are subjected to compression and friction, which prevents the roller 1 from wearing directly and extends the service life of the equipment.

[0025] The slots on both sides of the roller body 1 cooperate with the inserts 9 on the inner wall of the roller sleeve to form a preliminary positioning. During installation, the inserts 9 of the first roller sleeve 2 and the second roller sleeve 3 are aligned with the slots of the roller body 1 and inserted to ensure that the first roller sleeve 2 and the second roller sleeve 3 rotate coaxially with the roller body 1, avoiding additional wear caused by relative sliding.

[0026] The rotating shaft 4 inside the cavity of the roller body 1 can be manually rotated by the handle 19 at the end. The first bevel gear 5 on the rotating shaft 4 meshes with the second bevel gear 8 at the end of the screw 7 on the fixed plate 6, forming a right-angle transmission structure. When the handle 19 is turned, the first bevel gear 5 drives the second bevel gear 8 to rotate, which in turn drives the screw 7 to rotate around its own axis. This can drive the slider 14 to move, thereby moving the fixed sleeve 15 and the connecting seat 16, and performing stable adjustment of the clamping plate 11.

[0027] Rotating the handle 19 drives the screw 7 to rotate, and the slider 14 on the screw 7 moves along the screw axis, driving the connecting seat 16 to move through the fixed sleeve 15. The movable block 17 at the end of the connecting seat 16 slides in the movable groove of the clamping plate 11, pushing the clamping plate 11 to compress the torsion spring 12, so that the clamping plate 11 is disengaged from the groove of the insert block 9. At this time, the first roller sleeve 2 and the second roller sleeve 3 can be removed from the roller body 1.

[0028] Inside the rectangular groove on the inner wall of the roller body 1 slot, one end of the torsion spring 12 on the fixing rod 10 is connected to the clamping plate 11, and the other end is connected to the roller body 1. Under natural conditions, the elastic force of the torsion spring 12 pushes the clamping plate 11 to rotate around the fixing rod 10, so that the clamping plate 11 can be more smoothly clamped in the slot of the insert block 9, and the roller sleeve is rigidly fixed to the roller body 1 to prevent the roller sleeve from falling off during crushing operations.

[0029] When the sealing gasket 13 at the end of the clamping plate 11 is locked, it presses against the inner wall of the slot of the insert block 9. This enhances the stability of the clamping and prevents dust generated during the crushing process from entering the slot and cavity, thus avoiding wear or jamming of the parts. Multiple positioning blocks 18 on the side wall of the first roller sleeve 2 cooperate with the positioning groove on the side wall of the second roller sleeve 3 to ensure that the two roller sleeves are precisely aligned during installation and that the side walls fit tightly together, thus avoiding material jamming or uneven crushing particle size due to gaps.

[0030] Example 2

[0031] Reference Figure 1-3Multiple positioning blocks 18 are fixedly connected to the side wall of the first roller sleeve 2, and multiple positioning grooves are opened on the side wall of the second roller sleeve 3. Multiple positioning blocks 18 are respectively inserted into the inner wall of the multiple positioning grooves. A handle 19 is fixedly connected to the end of the rotating shaft 4 away from the first bevel gear 5.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
