DETAILED DESCRIPTION

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present application discloses a double-layer shredder.

[0035] Reference Figure 1 and Figure 2 The double-layer shredder comprises a frame 1, mounted on which are mounted a first shredder box 2 and a second shredder box 3. The first shredder box 2 is positioned above the second shredder box 3, with its discharge port facing downward and its feed port facing upward, receiving material that falls through the discharge port of the first shredder box 2. A translation mechanism 4 is provided between the second shredder box 3 and the frame 1 for moving the second shredder box 3 out from under the first shredder box 2. A drive unit 5 is also provided on the frame 1 for driving the second shredder box 3. When maintaining the interior of the second shredder box 3, the drive unit 5 drives the second shredder box 3 to move horizontally below the first shredder box 2, facilitating maintenance work within the second shredder box 3.

[0036] See also Figure 2 and Figure 3 Specifically, the frame 1 includes a first layer plate 11 and a second layer plate 12. The second layer plate 12 is located below and spaced apart from the first layer plate 11. A first shredder box 2 is fixed to the first layer plate 11, with its feed port facing upward and its discharge port extending downward through the first layer plate 11. A first shredder roller 21 is horizontally disposed within the first shredder box 2. The ends of the first shredder roller 21 are rotatably mounted on the longitudinal side walls of the first shredder box 2. Two first shredder rollers 21 are arranged side by side along the width of the first shredder box 2. A first motor 22 is fixed to the outer wall of the first shredder box 2. The lower side of the first motor 22 is fixed to the first layer plate 11, and the output shaft of the first motor 22 is transmission-connected to the first shredder roller 21, driving the rotation of the first shredder roller 21. The first motor 22 corresponds one-to-one with the first shredder roller 21.

[0037] See also Figure 3 and Figure 4 The second shredder box 3 is located on the second deck 12, with the translation mechanism 4 positioned between the second shredder box 3 and the second deck 12. The discharge port of the second shredder box 3 extends downward through the second deck 12. A second shredder roller 31 is horizontally mounted within the second shredder box 3. The two ends of the second shredder roller 31 are pivotally mounted on the longitudinal side walls of the second shredder box 3. Two second shredder rollers 31 are arranged side by side along the width of the second shredder box 3. A second motor 32 is fixed to the outer wall of the second shredder box 3 and is securely fastened to the second deck 12 via removable bolts 321. The output shaft of the second motor 32 is in transmission connection with the second shredder roller 31, driving the rotation of the second shredder roller 31. There is a one-to-one correspondence between the second motors 32 and the second shredder roller 31. To maintain the interior of the second shredder box 3, the removable bolts 321 corresponding to the two second motors 32 are removed. At this point, the two second motors 32 can move with the second shredder box 3 away from the bottom of the first shredder box 2.

[0038] See also Figure 2 and Figure 3 In this embodiment, fixing columns 13 are fixedly connected between the first and second decks 11, 12 to ensure the stability of the second deck 12 and the first shredder box 2. Of course, to enhance the load-bearing capacity of the second deck 12, temporary support columns 14 can be installed between the first and second decks 11, 12. These temporary support columns 14 are bolted to the first and second decks 11, 12. When personnel are working on the second deck 12, such as performing maintenance on the second shredder box 3, they can remove the temporary support columns 14 that are obstructing the movement of the second shredder box 3 and reinstall them after maintenance.

[0039] See also Figure 3 and Figure 4 The translation mechanism 4 includes rollers 41 and slide rails 42. The rollers 41 are double-sided pulleys, rotatably connected to the second shredder box 3. The rotation axis of the rollers 41 is parallel to the axis of the second shredder roller 31. A set of rollers 41 is provided on either side of the second shredder box 3 in the longitudinal direction. Each set of rollers 41 includes two rollers 41 spaced apart along the width of the second shredder box 3. The slide rails 42 are fixed to the second deck 12 below the rollers 41. They extend along the width of the second shredder box 3, with one slide rail 42 located below each set of rollers 41. The two slide rails 42 are parallel to each other, and the two sets of rollers 41 roll in engagement with their corresponding slide rails 42.

[0040] The driving component 5 is a cylinder 51. The cylinder body of the cylinder 51 is hinged to the frame 1. The axis of the piston rod of the cylinder 51 is parallel to the width direction of the second shredder box 3. The end of the piston rod of the cylinder 51 is hinged to the second shredder box 3. In addition, one cylinder 51 is provided on each side of the second shredder box 3 in the longitudinal direction.

[0041] To ensure consistent movement along the length of the second shredder box 3, a synchronization mechanism 6 is provided between the two longitudinal sides of the second shredder box 3. The synchronization mechanism 6 comprises a synchronization rack 61, a synchronization gear 62, and a synchronization shaft 63. The synchronization rack 61 is arranged along the length of the slide rail 42. Two synchronization racks 61 are provided, one adjacent to each slide rail 42 and fixed to the second deck 12. The axis of the synchronization shaft 63 is parallel to the length of the second shredder box 3. The synchronization shaft 63 is rotatably mounted on the second shredder box 3. Synchronization gears 62 are coaxially fixed to each end of the synchronization shaft 63, and the two synchronization gears 62 mesh with the two synchronization racks 61, respectively.

[0042] See also Figure 5 In order to ensure the stability of the second shredder box 3 on the lower side of the first shredder box 2, a first side panel 23 is fixed at the discharge port of the first shredder box 2, and a second side panel 33 is fixed at the feed port of the second shredder box 3 corresponding to the first side panel 23. When the second shredder box 3 is displaced to the lower side of the first shredder box 2, the first side panel 23 and the second side panel 33 abut against each other. A locking component 7 is connected between the first side panel 23 and the second side panel 33. The locking component 7 includes a locking bolt 71 and a locking nut 72. The locking bolt 71 and the locking nut 72 cooperate to lock the first side panel 23 and the second side panel 33. Before the oil cylinder 51 drives the second shredder box 3 to move, the locking bolt 71 and the locking nut 72 can be removed; after the second shredder box 3 moves to the working position, the locking bolt 71 and the locking nut 72 can be used to lock the first side panel 23 and the second side panel 33.

[0043] The operating principle of the double-layer shredder according to the embodiment of the present application is as follows: when performing maintenance on the interior of the second shredder box 3, the locking bolts 71, locking nuts 72, detachable bolts 321, and corresponding temporary support columns 14 can be removed first, and the fixed connection between the first side plate 23 and the second side plate 33 can be released, as well as the fixed connection between the second motor 32 and the second layer plate 12. Then, with the cooperation of the rollers 41 and the slide rails 42, the two oil cylinders 51 drive the second shredder box 3 to move, so that the second shredder box 3 is separated from the lower side of the first shredder box 2, thereby facilitating maintenance operations inside the second shredder box 3. At the same time, the synchronization rack 61, synchronization gear 62, and synchronization shaft 63 cooperate to ensure the consistency of the movement of both sides of the second shredder box 3 in the longitudinal direction.

[0044] After the maintenance of the second shredder box 3 is completed, the two oil cylinders 51 push the second shredder box 3 to the lower side of the first shredder box 2; after the second shredder box 3 moves to the working position, the first side plate 23 and the second side plate 33 are locked using the locking bolts 71 and the locking nuts 72, and the two second motors 32 are fixed to the second layer plate 12 using the detachable bolts 321, and the temporary support columns 14 are reinstalled.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
