Description

Technical Field

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

[0002] Toothed roll crushers are a type of crushing equipment widely used in many industrial fields. They mainly use special wear-resistant toothed rolls that rotate at high speed. The friction and extrusion force between the toothed rolls and the material are used to crush the material. During operation, the material falls from the feed inlet between the two toothed rolls and is crushed into the required particle size by the high pressure and shearing action of the rolls. Then it is sent out by the conveying equipment.

[0003] like Figure 1 As shown, the crusher includes a toothed roller crusher body 1 and two crushing toothed rollers 2 that are rotatably installed on the inner wall of the toothed roller crusher body 1. There are certain gaps between the two toothed rollers and the two sides of the inner wall of the toothed roller crusher. When the toothed roller crusher is in use, if material falls into the two gaps, it will jam the two toothed rollers and affect the subsequent crushing process. Therefore, a new type of protection device for the toothed roller crusher is needed to solve the above problems. Utility Model Content

[0008] Furthermore, each of the two main chambers has a plurality of second mounting bolts threaded onto its surface, and the surfaces of the plurality of second mounting bolts are threaded onto the inner wall of the toothed roller crusher body.

[0009] Furthermore, guide grooves are provided on the surfaces of both main compartments, and one end of each of the two mating frames is slidably inserted into the inner wall of the two guide grooves.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This embodiment provides a protection device for a toothed roller crusher, mainly to solve the problem that when material falls into the two gaps of a current toothed roller crusher, it will jam the two toothed rollers, affecting the subsequent crushing process. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-6Please provide a detailed explanation:

[0025] A protective device for a toothed roller crusher includes: two mounting chambers 3, each installed inside the toothed roller crusher body 1; and mating frames 4 slidably inserted into the inner walls of both mounting chambers 3. Each mating frame 4 has several mating teeth 5 on its surface. During use, when the user pours material into the toothed roller crusher body 1 for crushing, some material may become stuck between the mating teeth 5 and the two crushing toothed rollers 2. The rotating crushing toothed rollers 2 and the mating teeth 5 can then work together to crush the material. In rare cases, material may become stuck on the crushing toothed rollers 2. In this case, the two mating frames 4 can adaptively move a certain distance along the inner wall of the corresponding mounting chamber 3, allowing the stuck material to be carried out by the rotating crushing toothed rollers or fall into the toothed roller crusher body 1. The main components of the two mounting chambers 3 are... Two main chamber bodies 31 with baffles 32 slidably inserted into their inner walls are assembled by the user. During use, the user slides the two baffles 32 into the inner walls of the two main chamber bodies 31 respectively, and then threadedly inserts several first mounting bolts 33 into the surfaces of the two baffles 32, so that the surfaces of the first mounting bolts 33 are threaded into the surfaces of the main chamber bodies 31. The two main chamber bodies 31 are installed on the inner wall of the toothed roller crusher body 1 as follows: During use, the user slides the surfaces of the two main chamber bodies 31 into the inner wall of the toothed roller crusher body 1, and then threadedly inserts several second mounting bolts 8 into the surfaces of the two main chamber bodies 31, so that the surfaces of the second mounting bolts 8 are threaded into the inner wall of the toothed roller crusher body 1.

[0026] By setting two installation chambers 3 inside the toothed roller crusher body 1, and slidingly inserting a matching frame 4 into the inner wall of each of the two installation chambers 3, when the user pours material into the top of the toothed roller crusher body 1 for crushing, even if some material falls into the gap between the two crushing toothed rollers 2 and the two matching frames 4, several matching teeth 5 will cooperate with the two crushing toothed rollers 2 to crush. When the size of the material just touches the inside of the gap and causes blockage, the two matching frames 4 will slide on the inner wall of the two installation chambers 3 respectively, allowing the material to fall into the inside of the toothed roller crusher body 1. Finally, under the action of the force application unit 6, the two matching frames 4 will return to their original positions.

[0027] By fixing an installation rod 641 to the surface of each of the two mating frames 4, and fixing an installation block 643 to one end of each of the several insertion tubes 62, the user can slide the two connecting rods 642 into the inner walls of several grooves 644 respectively opened on the surfaces of the two installation rods 641 and several installation blocks 643 during use. Finally, several insertion rods 645 are slidably inserted into the surfaces of the two installation rods 641, so that the surfaces of the several insertion rods 645 are slidably inserted into the surfaces of the two connecting rods 642. The upper limit nut 646 is threaded onto the surfaces of the several insertion rods 645, thus achieving a stable connection between the mating frame 4 and one end of the several insertion tubes 62.

[0028] like Figure 4 As shown, in some embodiments, guide grooves 7 are provided on the surfaces of the two main compartments 31, and one end of the two mating frames 4 is slidably inserted into the inner wall of the two guide grooves 7 respectively. Therefore, when the two mating frames 4 move, one end of them will slide on the inner wall of the two guide grooves 7 respectively, ensuring stability during the movement.

[0029] like Figure 3 As shown, in some embodiments, the main components of the force-applying unit 6 are: several empty tubes 61 respectively fixedly installed on the inner walls of the two main chambers 31; insert tubes 62 are slidably inserted into the inner walls of the several empty tubes 61; and springs 63 are slidably sleeved on the surfaces of the several insert tubes 62. One end of each spring 63 is fixedly installed on the surface of the several insert tubes 62, and the other end of each spring 63 is fixedly installed on the inner wall of the several empty tubes 61. Therefore, in use, the user needs to first install the two mating frames 4 onto one end of each of the several insert tubes 62 through the connecting unit 64. Subsequently, after the two mating frames 4 move, the several insert tubes 62 will slide on the inner walls of the several empty tubes 61, further driving the several springs 63 to compress. Thus, the several insert tubes 62 can apply a force to the two mating frames 4 to maintain their original position. The main components of the connecting unit 64 are... The device consists of two mounting rods 641 and two connecting rods 642, which are respectively fixedly installed on the surfaces of two mating frames 4. Mounting blocks 643 are also fixedly installed at one end of several insertion tubes 62. Sliding grooves 644 are formed on the surfaces of the mounting blocks 643 and the two mounting rods 641. In use, the user first slides the two connecting rods 642 into the inner walls of the sliding grooves 644, then threadedly inserts several insertion rods 645 into the surfaces of the two mounting rods 641, allowing the insertion rods 645 to slide into the surfaces of the two connecting rods 642. Finally, upper limit nuts 646 are threaded onto the surfaces of the two connecting rods 642, thus connecting one end of the insertion tubes 62 to the two mating frames 4. Subsequent movement of the mating frames 4 will sequentially move the mounting rods 641, connecting rods 642, mounting blocks 643, and insertion tubes 62, ultimately compressing the spring 63.

[0030] like Figure 4 As shown, in some embodiments, limiting protrusions 9 are provided on the surfaces of both connecting rods 642. Therefore, after the user slides the two connecting rods 642 into the inner walls of the plurality of sliding grooves 644 respectively, the surfaces of the two limiting protrusions 9 will slide into the inner walls of the two sliding grooves 644 respectively, further strengthening the limiting of the two connecting rods 642 in the inner walls of the plurality of sliding grooves 644.

[0031] The working process of this utility model is as follows:

[0032] First, the user needs to slide the surfaces of the two connecting rods 642 into the inner walls of several grooves 644 respectively, slide several insert rods 645 into the surfaces of the two mounting rods 641 respectively, so that the surfaces of the several insert rods 645 are also inserted into the surfaces of the two connecting rods 642 respectively, and finally thread the upper limit nut 646 onto the surfaces of the several insert rods 645 respectively, thus completing the installation of one end of several insert tubes 62 and two mating brackets 4 respectively;

[0033] Secondly, the user needs to slide the two baffles 32 into the inner walls of the two main chambers 31 respectively, and fix them with several first mounting bolts 33. Then, the two main chambers 31 are slid into the inner walls of the toothed roller crusher body 1 respectively, and fixed with several second mounting bolts 8. The assembly is then complete. In subsequent use, the user pours the material into the interior of the toothed roller crusher body 1. If the material is stuck between several mating teeth 5 and the crushing toothed roller 2, the mating frame 4 will move and retract under the continuous rotation of the crushing toothed roller 2, so that the material can be smoothly discharged from the gap.

[0034] 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.
