Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] Please refer to Figures 1-7 The utility model discloses a tooth roll type crushing device, including box 1 and two tooth rolls 2 set in the box 1, tooth roll 2 includes rotating setting rotating shaft part 21 in the box 1, the detachable setting of rotating shaft part 21 has multiple annular distribution tooth-shaped crushing parts 22, rotating shaft part 21 still is provided with the locking mechanism 23 for locking multiple tooth-shaped crushing parts 22 simultaneously, prevents tooth-shaped crushing part 22 from separating rotating shaft part 21,

[0027] Still include driving mechanism 3, for driving two tooth rolls 2 rotation, crushing the material between two tooth rolls 2.

[0028] The utility model discloses a plurality of tooth-shaped crushing parts 22 are installed on rotating shaft part 21, and utilize locking mechanism 23 to lock multiple tooth-shaped crushing parts 22 simultaneously to the mode of forming tooth roll 2, so that tooth roll 2 needs to be maintained when being damaged, only needs to operate locking mechanism 23 to unlock, can make the disassembly of multiple tooth-shaped crushing parts 22 not be hindered, and maintenance personnel is convenient to dismount, can effectively improve maintenance efficiency.

[0029] It needs to be explained that driving mechanism 3 belongs to mature prior art, and here is not too much elaboration.

[0030] In an embodiment, rotating shaft part 21 includes middle section 211 and lifting section 212 setting in both ends of middle section 211, and the outer diameter of middle section 211 is greater than the outer diameter of lifting section 212.

[0031] The tooth-shaped crushing part 22 comprises a circular arc plate 221, the inner diameter of the circular arc plate 221 is equal to the outer diameter of the middle section 211, the convex side of the circular arc plate 221 is provided with a plurality of crushing teeth 222, and the concave side of the circular arc plate 221 is provided with a T-shaped guide strip 223, and the length of the T-shaped guide strip 223 is less than the length of the circular arc plate 221.

[0032] The middle section 211 is provided with a guide groove at the end away from the driving mechanism 3, the T-shaped guide strip 223 moves along the axis direction of the middle section 211, and the lifting section 212 is not located in the movement area of the T-shaped guide strip 223.

[0033] In this way, after the tooth-shaped crushing part 22 is assembled with the rotating shaft part 21, the circular arc plate 221 can tightly abut against the middle section 211, can stably bear the extrusion force applied in the crushing process, and because the length of the T-shaped guide strip 223 is less than the length of the circular arc plate 221 when the tooth-shaped crushing part 22 is installed, the locking mechanism 23 only needs to limit the insertion side of the guide groove, so that the tooth-shaped crushing part 22 and the rotating shaft part 21 can be prevented from being separated, and the disassembly and assembly difficulty can be effectively reduced.

[0034] In an embodiment, the box body 1 is provided with a maintenance hole for the tooth-shaped crushing part 22 to enter and exit the box body 1 at the side away from the driving mechanism 3, the maintenance hole is located at the bottom of the axis of the rotating shaft part 21, and the box body 1 is detachably provided with a cover plate 4 for plugging the maintenance hole.

[0035] In this way, when the tooth-shaped crushing part 22 is disassembled and maintained, the entire tooth roller 2 does not need to be taken out from the tooth-roller type crushing device, and the disassembly and assembly difficulty can be further reduced.

[0036] The specific operation mode is that the cover plate 4 corresponding to the tooth roller 2 is first removed, then the tooth-shaped crushing part 22 to be disassembled is rotated to be aligned with the maintenance hole, the locking mechanism 23 is released, and then the tooth-shaped crushing part 22 is pulled out from the maintenance hole by holding the crushing teeth 222.

[0037] In an embodiment, the locking mechanism 23 comprises a baffle 231 sleeved on the lifting section 212 at the end away from the driving mechanism 3, the outer diameter of the baffle 231 is not less than the outer diameter of the middle section 211, at least one groove is formed in the baffle 231 for the tooth-shaped crushing part 22 to enter and exit the guide groove, an end ring 232 is arranged on the side of the baffle 231 away from the middle section 211 and is sleeved with the lifting section 212, a spring latch 233 is detachably arranged on the end ring 232, a plug groove is formed in the lifting section 212 for the spring latch 233 to be inserted, and when the spring latch 233 is in the locked state, the spring latch 233 is inserted into the plug groove and the baffle 231 is located in the movement area of the plurality of tooth-shaped crushing parts 22, and when the spring latch 233 is in the unlocked state, the spring latch 233 is located outside the plug groove.

[0038] In this way, when the tooth-shaped crushing part 22 is disassembled, only the spring bolt 233 needs to be adjusted to the unlocked state, then the baffle 231 is rotated to align the T-shaped guide bar 223 on the tooth-shaped crushing part 22 to be disassembled or assembled, so that the tooth-shaped crushing part 22 can be pulled out without obstruction, and after the maintenance of the tooth-shaped crushing part 22 is completed, the spring bolt 233 is adjusted to the locked state by rotating the baffle 231, so that the plurality of tooth-shaped crushing parts 22 can be simultaneously locked, thereby achieving the effect of convenient disassembly and maintenance.

[0039] In an embodiment, a plurality of balls are arranged on the side of the end ring 232 away from the baffle 231, and the balls abut against the inner wall of the box body 1 when the baffle 231 abuts against the middle section 211.

[0040] In this way, after the locking mechanism 23 is installed, the two sides abut against the middle section 211 and the inner wall of the box body 1, respectively, so that the locking mechanism 23 cannot change the position on the lifting section 212 due to working factors, thereby effectively improving the locking stability of the tooth-shaped crushing part 22, and due to the arrangement of the balls, the rolling effect of the balls can effectively reduce the frictional resistance between the locking mechanism 23 and the box body 1 when the locking mechanism 23 rotates with the rotating shaft part 21.

[0041] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

[0042] In addition, if the embodiments of the present application involve descriptions of “first”, “second”, etc., the descriptions of “first”, “second”, etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first” and “second” can explicitly or implicitly include at least one of the features.
