Description

Technical Field

[0001] This application relates to the field of crusher structural components, and in particular to a comb plate for a double-toothed roller crusher. Background Technology

[0002] A double-toothed roll crusher is a crushing device that uses two toothed rollers rotating in opposite directions to squeeze, shear, and tear materials. The comb plate is one of the core components of a double-toothed roll crusher; it specifically refers to the comb-shaped toothed plate installed inside the side plate of the crusher housing. Its function is to allow material to enter between the two crushing rollers, preventing material from flowing out uncrushed from one side of the rollers. Due to the functional characteristics of the comb plate, material often collides with it, causing the comb plate to wear out too quickly and requiring frequent replacement.

[0003] However, currently, the comb plates of double-toothed roller crushers are directly fixed to the side plates of the crusher housing with bolts. Once wear occurs, the comb plates need to be removed, which requires manual handling. Most integral comb plates weigh over 50 kg, and the disassembly and installation process requires the cooperation of multiple workers, which is time-consuming and labor-intensive. Utility Model Content

[0004] To facilitate the disassembly and installation of the comb plate and save manpower, this application provides a comb plate for a double-toothed roller crusher.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a comb plate for a double-toothed roller crusher.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A comb plate for a double-toothed roll crusher includes a body 1, an adjusting assembly 2, a mounting base 3, bolts 4, and nuts 5. It should be noted that the double-toothed roll crusher comprises two meshing toothed rolls and a crusher housing.

[0023] The main body 1 has a lifting hole 11, and a perforated plate 7 is threaded onto the lifting hole 11. The perforated plate 7 has a screwing groove 71. When the main body 1 needs to be replaced due to wear, since the weight of a single main body 1 is less than 50 kg, the operator can remove the perforated plate 7 from the lifting hole 11 by screwing it. Then, the operator can use a lifting device to remove the main body 1 from the side wall of the crusher housing through the lifting hole 11. Similarly, the operator can use the same lifting device to install the new main body 1 onto the side wall of the crusher housing through the lifting hole 11. This eliminates the need for multiple operators to work together to disassemble and install the main body 1, thus saving manpower. It should be noted that the perforated plate 7 is designed to avoid affecting the hardness of the main body 1 and to reduce the deformation of the main body 1 during use.

[0024] The main body 1 is in the shape of a right trapezoid. The upper bottom edge of the main body 1 is close to the tooth root of the tooth roller. The mounting base 3 is fixedly installed on the lower bottom edge of the main body 1. The mounting base 3 has two first threaded holes 31. The adjusting component 2 is installed on the end of the mounting base 3 away from the main body 1. The adjusting component 2 has a second threaded hole 6 corresponding to the first threaded hole 31. The bolt 4 passes through the first threaded hole 31, the second threaded hole 6 and the threaded hole (not shown) on the side wall of the crusher box in sequence, and is threadedly connected to the nut 5, thereby installing the main body 1 on the side wall of the crusher box.

[0025] The adjusting assembly 2 includes a first adjusting plate 21, a second adjusting plate 22, an adjusting screw 24, and an adjusting screw cylinder 23. Both the first adjusting plate 21 and the second adjusting plate 22 have two second threaded holes 6. The adjusting screw 24 and the adjusting screw cylinder 23 are located between the first adjusting plate 21 and the second adjusting plate 22. The adjusting screw 24 is threaded into the adjusting screw cylinder 23. The adjusting screw 24 is fixedly connected to the second adjusting plate 22. A T-shaped circular block 231 is installed on the adjusting screw cylinder 23. A T-shaped circular groove 211 is formed on the first adjusting plate 21. The T-shaped circular block 231 is rotatably connected to the first adjusting plate 21 through the T-shaped circular groove 211. The first adjusting plate 21 is located at the end of the mounting base 3 opposite to the main body 1. The outer wall of the adjusting screw cylinder 23 is hexagonal.

[0026] When the gap between the two toothed rollers changes, the operator can use an auxiliary wrench (not shown) to turn the adjusting screw 23, causing the adjusting screw 23 and the adjusting screw 24 to rotate, so that the adjusting screw 23 and the adjusting screw 24 move closer or further away from each other, thereby causing the first adjusting plate 21 and the second adjusting plate 22 to move closer or further away from each other, and thus causing the body 1 to move closer or further away from the corresponding toothed roller.

[0027] It should be noted that, due to the tight threaded connection between bolt 4 and nut 5, the first adjusting plate 21 and the second adjusting plate 22 apply pressure to the corresponding adjusting screw 23 and adjusting screw 24 respectively. When the double toothed roll crusher vibrates during operation, it will not cause the adjusting screw 23 to rotate, and thus will not affect the working state of the main body 1.

[0028] The implementation principle of the comb plate of a double-toothed roller crusher in this application embodiment is as follows: Bolt 4 passes through the first threaded hole 31, the second threaded hole 6, and the threaded hole (not shown) on the side wall of the crusher housing in sequence, and is threadedly connected to the nut 5, thereby installing the body 1 on the side wall of the crusher housing. When it is necessary to adjust the distance between the body 1 and the toothed roller, the worker turns the bolt 4 in the reverse direction and lifts the body 1 with the hoisting equipment. Then, the worker turns the adjusting screw 23 with the auxiliary wrench to increase or decrease the distance between the mounting base 3 and the side wall of the crusher housing. After reaching the appropriate position, the worker turns the bolt 4 in the forward direction to fix the body 1. When the body 1 is worn and needs to be replaced, the worker removes the body 1 from the side wall of the crusher housing through the hoisting hole 11 with the hoisting equipment. Similarly, the worker uses the hoisting equipment to install the new body 1 on the side wall of the crusher housing through the hoisting hole 11. This eliminates the need for multiple workers to work together to disassemble and install the body 1, thus saving manpower.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
