Technical Field

[0001] The utility model relates to the technical field of blades, in particular to a crusher blade. Background Art

[0002] Crusher can process various types of raw materials, including plastic, metal, wood, glass, paper, etc., and process them into fragments or powders of the required particle size. Since crushers usually need to process a large amount of raw materials, it is necessary to regularly check the blades, detect wear in time, and perform maintenance or replacement to ensure the normal working condition of the blades. Most existing blades are one-piece structures. After wear, even if the metal condition at the center is good, the blade needs to be replaced as a whole, resulting in material waste and increased replacement costs. In view of this, the utility model proposes a crusher blade. Utility Model Content

[0003] The utility model aims to propose a crusher blade in view of the problem in the background technology that the blade needs to be replaced as a whole after being worn, which causes waste of materials and increases the replacement cost.

[0008] Optionally, the fixing mechanism further comprises a clamping plate fixedly connected to an end of the rack away from the gear ring, and the clamping plate is slidably connected to the limit block.

[0009] Compared with the prior art, the utility model has the following beneficial technical effects:

[0010] The utility model provides a contact layer, so that the contact layer contacts with the material to break it during use, and only the contact layer can be replaced after being worn, thereby reducing the number of parts to be replaced and thus reducing the maintenance cost;

[0011] Furthermore, by setting the limiting assembly, the contact layer can be stably installed on the outside of the mounting block, and the position of the limiting assembly is fixed by cooperating with the fixing mechanism, so that the position of the contact layer is fixed, preventing the contact layer from being displaced during use and causing accidents;

[0027] Example

[0028] like Figure 1-4As shown, a crusher blade proposed by the utility model includes a mounting block 1 and a contact layer 2 slidably arranged on the outer ring of the mounting block 1. The contact layer 2 will be worn during use. The mounting block 1 and the contact layer 2 are jointly provided with a limiting assembly 3 for limiting the contact layer 2. The limiting assembly 3 includes a slot 31 and a limiting plate 32. The slot 31 is opened on one side of the contact layer 2. The limiting plate 32 installed on one side of the mounting block 1 corresponds to the position of the slot 31. After the contact layer 2 is installed on the outer side of the mounting block 1, the limiting action of the limiting plate 32 keeps the contact layer 2 and one side of the mounting block 1 in the same plane. The limiting assembly 3 also includes a fixed block 33, a slider 34, and a limiting block 35. Multiple groups of fixed blocks 33 are fixedly connected to the inner wall of the contact layer 2, and the fixed block 33 moves synchronously with the contact layer 2. The slider 34 is slidably connected to the fixed block 33. The cross section of the slider 34 is a T-shaped structure, so that the connected structure is stable and slides smoothly. The limit block 35 is fixedly connected to the end of the slider 34 away from the contact layer 2. The contact layer 2 is slidably connected to the slider 34 and the limit block 35 through the fixed block 33. At the same time, when the contact layer 2 is replaced, the slider 34 and the limit block 35 can also be retained, further reducing the maintenance cost. One side of the fixed block 33 and the side of the contact layer 2 away from the slot 31 are kept in the same plane. The fixed block 33 and the limit block 35 are both slidably connected to the mounting block 1, so that the contact layer 2 can be slidably installed to the outside of the mounting block 1 through the fixed block 33 and the limit block 35, and the position of the contact layer 2 is further positioned.

[0029] For details, please refer to Figure 2 and Figure 5The blade also includes a fixing mechanism 4 disposed in the mounting block 1 to fix the contact layer 2 after the mounting. The fixing mechanism 4 includes a rotating rod 41 and a first gear 42. The rotating rod 41 is rotatably connected to the mounting block 1, and the rotating rod 41 rotates in place. One end of the rotating rod 41 passes through the surface of the mounting block 1 and extends into the cavity inside the mounting block 1. The first gear 42 disposed in the cavity is fixedly connected to one end of the rotating rod 41. When the rotating rod 41 rotates, the first gear 42 is driven to rotate synchronously. The fixing mechanism 4 also includes a gear ring 43, a second gear 44, and a rack 45. The gear ring 43 rotates in place in the cavity. The first gear 42 is meshed with the gear ring 43, and is used for the first gear 42 to drive the gear ring 43 to rotate synchronously when the first gear 42 rotates. A plurality of groups of second gears 44 are distributed in an annular array outside the gear ring 43 and meshed with it. When the gear ring 43 rotates, the plurality of groups of second gears 44 are driven to rotate synchronously. The rack 45 is arranged on one side of the gear ring 43 and is also meshed with the second gear 44. When the second gear 44 rotates, it drives the rack 45 to slide in the mounting block 1. The fixing mechanism 4 also includes a clamping plate 46 fixedly connected to the end of the rack 45 away from the gear ring 43. When the rack 45 moves, it drives the clamping plate 46 to move synchronously. The clamping plate 46 is slidably connected to the limit block 35. After moving, the clamping plate 46 enters the limit block 35 to limit the limit block 35, thereby fixing the contact layer 2 to prevent it from falling off.

[0030] In this embodiment, when the contact layer 2 is replaced, first use a screwdriver to rotate the rotating rod 41, the rotating rod 41 drives the first gear 42 to rotate, and the first gear 42 engages with the gear ring 43 to drive the gear ring 43 to rotate. When the gear ring 43 rotates, it drives multiple groups of second gears 44 to rotate synchronously, and each group of second gears 44 engages with a group of racks 45 to drive the racks 45 to move, so that the racks 45 drive the clamping plate 46 to move out of the limit block 35. At this time, the contact layer 2 is moved, and the fixed block 33 and the limit block 35 slide on the installation block 1 away from the side of the limit plate 32, so that the contact layer 2 is removed for replacement, and the old slider 34 and the limit block 35 are slidably installed in the slider 34 on the inner side of the new contact layer 2. Then, the new contact layer 2 is slidably installed on the outside of the installation block 1, and the fixed block 33 and the limit block 35 are slidably installed on the installation block 1, and at the same time, one side of the contact layer 2 is closely attached to the limit plate 32. Finally, a screwdriver is used to rotate the rotating rod 41 so that the multiple sets of racks 45 drive the clamping plate 46 to enter the limiting block 35 for limiting.

[0031] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
