[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A detachable crusher crushing roller includes a mounting plate 1. A limiting block 11 is welded and fixed to the left end of the mounting plate 1. The left end of the limiting block 11 passes through the right end of the outer shell 23. A slot 12 is provided on the top of the limiting block 11 to cooperate with two insert plates 27 to limit the relative position of the limiting block 11 and the outer shell 23.

[0028] Furthermore, a mounting rod 13 is welded and fixed at the center of the right side surface of the mounting plate 1 for mounting the movable plate 15. A limiting plate 14 is provided at the right end of the mounting rod 13. The left side surface of the limiting plate 14 is in close contact with the right side surface of the rightmost movable plate 15 to limit the position of the movable plate 15.

[0029] Specifically, a number of movable disks 15 are provided between the limiting disk 14 and the mounting disk 1. The movable disks 15 are arranged at equal intervals, and two adjacent movable disks 15 are closely fitted together. The left side surface of the leftmost movable disk 15 is closely fitted with the right side surface of the mounting disk 1.

[0030] Specifically, a number of crushing teeth 151 are welded and fixed on the outer circumference of the movable disk 15. The crushing teeth 151 are arranged in a uniform and equidistant manner to crush items.

[0031] Specifically, positioning rods 16 are symmetrically welded and fixed on the right side surface of the mounting plate 1 near the upper and lower sides for mounting the movable plate 15. The right end of the positioning rod 16 passes through the right end of all movable plates 15 and the right end of the limiting plate 14 and is welded and fixed with a threaded rod 17 for mounting the limiting nut 18.

[0032] Specifically, the threaded rod 17 is threadedly connected to a limiting nut 18, and the left side surface of the limiting nut 18 is in close contact with the right side surface of the limiting disc 14 to limit the position of the limiting disc 14.

[0033] As a preferred embodiment, the mounting plate 1 is provided with a mounting mechanism 2 on the left side. The mounting mechanism 2 includes a mounting base 21. The mounting base 21 has threaded holes 22 at the four corners on the left side to facilitate the installation of the device onto the output shaft of the drive mechanism.

[0034] Specifically, the right end of the mounting base 21 is fixedly connected to the outer shell 23 by bolts. The right side surface of the outer shell 23 is in contact with the left side surface of the mounting plate 1 and is used to install the adjustment motor 24.

[0035] Specifically, an adjusting motor 24 is fixedly connected to the top of the inner wall of the outer casing 23 by bolts, which drives the bidirectional threaded rod 25 to rotate. The output shaft of the adjusting motor 24 is coaxially connected to the bidirectional threaded rod 25. The bidirectional threaded rod 25 has symmetrical threads with opposite directions near the upper and lower sides, so that when the bidirectional threaded rod 25 rotates, the two sliders 26 move in opposite directions.

[0036] Specifically, sliders 26 are symmetrically threaded near the upper and lower sides of the bidirectional threaded rod 25. The left side surface of slider 26 is in contact with the left side surface of the inner wall of the outer casing 23, which is used to drive the insert plate 27 to move.

[0037] Specifically, the right end of the slider 26 is fixedly connected to the insert plate 27 by bolts. The insert plate 27 is inserted into the inner wall of the slot 12 to limit the relative position of the limit block 11 and the outer shell 23.

[0038] In actual use, when it is necessary to remove the device from the drive mechanism, the user first turns on the adjustment motor 24. The adjustment motor 24 drives the bidirectional threaded rod 25 to rotate, thereby driving the two sliders 26 to move away from the limit block 11, thereby driving the two insert plates 27 to move away from the limit block 11.

[0039] When the ends of the two insert plates 27 away from the limiting block 11 are respectively attached to the top and bottom of the inner wall of the outer shell 23, the two insert plates 27 no longer engage with the inner wall of the slot 12. Move the mounting plate 1 to the right, thereby driving the limiting block 11 to move to the right. When the limiting block 11 no longer contacts the outer shell 23, the device is disassembled.

[0040] When the breaking tooth 151 on a certain moving disk 15 is damaged, the user first rotates the two limit nuts 18 to move the two limit nuts 18 to the right until the two limit nuts 18 are no longer threadedly connected to the two threaded rods 17 respectively, and moves the limit disk 14 to the right until the limit disk 14 is no longer in contact with the two positioning rods 16 respectively.

[0041] Move all moving discs 15 to the right until the moving disc 15 with the broken tooth 151 is no longer in contact with the mounting rod 13 and the two positioning rods 16. Then move the moving disc 15 that is still in contact with the positioning rod 16 to the left and install the remaining moving discs 15 into the designated position. Then install the moving disc 15 with the new broken tooth 151 into the designated position. Move all moving discs 15 to the left so that the left side surface of the leftmost moving disc 15 is in contact with the right side surface of the mounting disc 1 and the two adjacent moving discs 15 are in close contact.

[0042] Install the limiting plate 14 back to its initial position, then thread the two limiting nuts 18 to the two threaded rods 17 respectively, and continue to rotate the two limiting nuts 18, thereby driving the two limiting nuts 18 to move to the left until the left side surface of the two limiting nuts 18 is tightly attached to the right side surface of the limiting plate 14, the position of the limiting plate 14 is limited, and the new moving plate 15 is installed.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
