Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of crusher toothed roller structure, and particularly relates to a crusher toothed roller assembly. Background Technology
[0002] Roll crushers typically consist of two parallel toothed rollers, each with multiple toothed discs arranged in a staggered pattern along its length. During operation, the rollers rotate vertically downwards on opposite sides, using the staggered toothed discs to crush the material. The crushed material then automatically falls between the rollers. This type of crusher primarily utilizes the shearing structure formed by the sides of adjacent toothed discs to crush the material. However, it produces a relatively large volume of crushed material and has a lower crushing efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a crusher toothed roller assembly that can effectively improve crushing efficiency and prevent damage to the crushing teeth.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A crusher toothed roller assembly includes: a pair of parallel and horizontally arranged toothed rollers, with the opposite side of the toothed rollers rotating downwards; each toothed roller includes a roller shaft, on which multiple circular toothed discs and circular partitions are coaxially arranged, with the toothed discs and partitions arranged alternately.
[0006] The outer diameter of the partition is smaller than the outer diameter of the toothed disc, and the partition on one roller shaft is aligned with the toothed disc on the other roller shaft along the axial direction of the roller shaft.
[0007] The toothed disc has multiple tooth grooves arranged in a circumferential array on its periphery, and a breaking tooth is formed between adjacent tooth grooves.
[0008] The partition has multiple inclined slots arranged in a circumferential array on its periphery, with fewer inclined slots than toothed slots.
[0009] The beneficial effects of this utility model are as follows: This solution not only utilizes the shearing structure formed by the sides of adjacent toothed discs on the two toothed rollers to crush materials, but also utilizes the outer edge of the crushing teeth and the outer wall of the partition to form a second shearing structure when the toothed discs rotate, which helps to improve crushing efficiency. Attached Figure Description

[0011] Figure 1 A schematic diagram of the overall structure of this application is shown.
[0012] Figure 2 An end view of the overall structure of this application is shown.
[0013] Figure 3 The diagram shows the working state of the gear disk when the partition is a complete circle.
[0014] The markings in the diagram are: roller shaft-1, toothed disc-2, toothed groove-21, crushing tooth-22, through hole-23, partition plate-3, and inclined groove-31. Detailed Implementation
[0015] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0016] like Figure 1 , Figure 2 As shown, a crusher toothed roller assembly includes: a pair of parallel and horizontally arranged toothed rollers, with the opposite side of the toothed rollers rotating downwards. Each toothed roller includes a roller shaft 1, and multiple circular toothed discs 2 and circular partitions 3 are coaxially arranged on the roller shaft 1. The toothed discs 2 and partitions 3 are staggered, and the toothed discs 2 are evenly separated by the partitions 3.
[0017] The outer diameter of the partition 3 is smaller than the outer diameter of the toothed disc 2. The partition 3 on one roller shaft 1 and the toothed disc 2 on another roller shaft 1 are aligned in the axial direction of the roller shaft 1. This can also be understood as the partition 3 on one roller shaft 1 and the toothed disc 2 on another roller shaft 1 being arranged in pairs.
[0018] The toothed disc 2 has multiple tooth grooves 21 arranged in a circumferential array on its periphery, and a breaking tooth 22 is formed between adjacent tooth grooves 21.
[0019] The partition 3 has multiple inclined slots 31 arranged in a circumferential array on its periphery, and the number of inclined slots 31 is less than that of toothed slots 21.
[0020] The crusher toothed roller assembly with the above-described structure can not only utilize the shearing structure formed by the sides of adjacent toothed discs 2 on the two toothed rollers to crush materials, but also form a second shearing structure with the outer edge of the crushing teeth 22 and the outer wall of the partition 3 when the toothed discs 2 rotate, thereby improving crushing efficiency. Because the number of inclined grooves 31 is less than that of toothed grooves 21, even if some crushing teeth 22 overlap with inclined grooves 31 during crushing, preventing the formation of a second shearing structure, other crushing teeth 22 will still cooperate with the outer wall of the partition 3 to form a second shearing structure, achieving the purpose of crushing. Although the inclined grooves 31 overlapping with the crushing teeth 22 cannot form a shearing structure, they can be used to discharge materials that are too hard and not crushed by the crushing teeth 22 downwards, preventing damage to the crushing teeth 22. The purpose of setting the inclined grooves 31 is to prevent materials from slipping on the outer wall of the partition 3, such as... Figure 3 As shown, if the outer wall of the partition 3 does not have a groove 31, when the side length of the material on the toothed disc 2 is greater than the opening width of the groove 21, when the partition 3 rotates, the end of the material that contacts the outer wall of the partition 3 will easily slide on the outer wall of the partition 3, thus preventing the material from quickly entering the shearing mechanism for crushing; after the partition 3 has a groove 31, the material can be quickly pushed into the shearing structure formed by the partition 3 and the crushing tooth 22 for crushing.
[0021] Preferred, such as Figure 2 As shown, both the toothed groove 21 and the inclined groove 31 are V-shaped structures, and their opening directions are inclined toward the direction of rotation of the corresponding roller shaft 1, so as to smoothly bite the material and prevent the material from lingering above the toothed roller.
[0022] Preferred, such as Figure 2 As shown, the distance between the root of the tooth groove 21 and the axis of the corresponding roller shaft 1 is less than the radius of the partition plate 3. This structure allows materials that cannot be crushed by the crushing tooth 22 to quickly enter the inclined chute 31 and be discharged downwards.
[0023] Preferred, such as Figure 1 , Figure 2 As shown, the roots of both the tooth groove 21 and the inclined groove 31 are semi-circular structures to avoid stress concentration and prevent cracks from forming at the roots of the tooth groove 21 and the inclined groove 31.
[0024] Preferred, such as Figure 1 , Figure 2 As shown, both the toothed disc 2 and the partition plate 3 have through holes 23, and the toothed disc 2 and the partition plate 3 of the same set of toothed rollers are aligned one by one to form a heat dissipation channel for the toothed rollers so as to quickly dissipate the heat of the toothed disc 2 and the partition plate 3.
[0025] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
