[0002] Paper archives are documents, drawings, manuscripts, diaries, etc., preserved using paper as a medium. They are non-reproducible and require confidentiality. Construction projects, as part of building projects, generate a large amount of information during construction. The classification and processing of this information is crucial in construction projects, and the most common tasks are the collection, storage, and destruction of information archives.

[0003] A Chinese patent (publication number CN220004168U) discloses a paper document shredding device. The shredding box is equipped with a shredding collection box and a handle inside the shredding chamber, which facilitates the sliding assembly and disassembly of the shredding collection box, thereby collecting the paper documents that are subsequently shredded by the rotating shredding and stirring shaft.

[0004] However, when using the paper document shredding device designed above, after shredding a large number of documents, the inside of the shredding collection box is quite full, and it is necessary to empty the shredding collection box. When removing the shredding collection box, it is necessary to turn off the shredding and stirring shaft, pause the shredding, and wait for the equipment to stop completely before the collection box can be pulled out. After emptying, it can be reinstalled and the equipment restarted. The operation process takes a long time and reduces the efficiency of staff in shredding documents.

[0005] To address this issue, we designed an engineering archive shredding and processing device. Utility Model Content

[0006] The purpose of this invention is to provide an engineering archive shredding and processing device to solve the problems mentioned in the background art.

A turntable is rotatably mounted on the top of the base, and a collection box is provided inside the turntable. A mounting rod is fixedly mounted at the center of the top of the base. Multiple collection boxes are arranged in a circumferential array along the mounting rod inside the turntable. The turntable is rotatably sleeved on the mounting rod. A shredding component is provided on the mounting box. By rotating the turntable around the mounting rod, the collection boxes are rotated, so that the collection boxes are placed inside or outside the mounting box.

[0008] Furthermore, a positioning box is fixedly installed on the outside of the mounting box, and an installation groove is opened inside the positioning box. A limit rod is inserted into the installation groove, and a telescopic spring is sleeved on the outside of the limit rod. A sliding plate is slidably installed inside the installation groove, and the limit rod is fixed on the sliding plate. One end of the telescopic spring is fixedly connected to the sliding plate, and the other end of the telescopic spring is fixedly connected to the inner wall of the installation groove. The end of the limit rod facing the turntable is inserted into the turntable.

[0009] Furthermore, the turntable has limit holes on its outer side, the number of which is the same as the number of turntables, and the limit rod is inserted into the limit hole to limit the turntable.

[0010] Furthermore, a handle is fixedly connected to the end of the limiting rod away from the turntable, and the handle is located on the outside of the positioning box.

[0011] Furthermore, the crushing assembly includes a crushing box disposed on the top of the mounting box, a rotating motor is fixedly installed on the outer side of the crushing box, a crushing roller is rotatably installed inside the crushing box, the output shaft of the rotating motor is connected to the crushing roller, and a feeding protective cover is fixedly installed on the top of the crushing box, the feeding protective cover being connected to the interior of the crushing box.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-5This utility model provides a technical solution: it includes a circular base 1 and a mounting box 2 connected to one side of the top of the base 1. A turntable 7 is rotatably mounted on the top of the base 1. A collection box 9 is provided inside the turntable 7. An mounting rod 11 is fixedly mounted at the center of the top of the base 1. The number of collection boxes 9 is set to multiple. Multiple collection boxes 9 are installed in a circumferential array along the mounting rod 11 inside the turntable 7. The turntable 7 is rotatably sleeved on the mounting rod 11. The mounting box 2 is provided with a crushing component. By rotating the turntable 7 around the mounting rod 11, the collection boxes 9 are driven to rotate, so that the collection boxes 9 are placed inside or outside the mounting box 2. A support plate 10 that can rotate on the top of the mounting rod 11 is provided on the top of the mounting rod 11. The support plate 10 is fixedly connected to one side of the mounting box 2. There are four collection boxes 9.

[0021] In practice, staff can put the documents to be shredded into the feeding protective cover 5, start the rotating motor 4, drive the shredding roller 6 to rotate, and the shredding roller 6 will shred the documents. The shredded waste paper will fall into the collection box 9. After a large number of documents are shredded, the turntable 7 can be rotated to rotate the collection box 9 located inside the mounting box 2 out of the mounting box 2, and rotate an empty collection box 9 into the mounting box 2, so that the collection box 9 full of shredded documents can be dumped without stopping the shredding roller 6.

[0022] See Figure 1 , Figure 4 and Figure 5 A positioning box 13 is fixedly installed on the outside of the mounting box 2. The positioning box 13 has an installation groove 14 inside. A limit rod 16 is inserted into the installation groove 14. A telescopic spring 17 is sleeved on the outside of the limit rod 16. A sliding plate 15 is slidably installed inside the installation groove 14. The limit rod 16 is fixed on the sliding plate 15. One end of the telescopic spring 17 is fixedly connected to the sliding plate 15, and the other end of the telescopic spring 17 is fixedly connected to the inner wall of the installation groove 14. The end of the limit rod 16 facing the turntable 7 is inserted into the turntable 7. A limit hole 8 is opened on the outside of the turntable 7. The number of limit holes 8 is the same as the number of turntables 7. The limit rod 16 is inserted into the limit hole 8 to limit the turntable 7. A handle 18 is fixedly connected to the end of the limit rod 16 away from the turntable 7. The handle 18 is located on the outside of the positioning box 13.

[0023] It should be noted that the side of the positioning box 13 closest to the turntable 7 is set to be arc-shaped, which does not affect the rotation of the turntable 7.

[0024] In practice, when the turntable 7 is rotated, the operator holds the handle 18 with one hand and pulls the handle 18 away from the positioning box 13. When the handle 18 moves, it causes the limiting rod 16 to slide inside the positioning box 13. One end of the limiting rod 16 moves away from the limiting hole 8, and the other hand can then rotate the turntable 7. After releasing the hand holding the handle 18, during the rotation, the other limiting hole 8 rotates to one side of the base 1. Under the force of the return of the telescopic spring 17, the sliding plate 15 slides in the mounting groove 14. The limiting rod 16 moves with the sliding plate 15 and approaches the limiting hole 8, thereby inserting into the interior of the limiting hole 8 and limiting the turntable 7 so that the appropriate collection box 9 is located inside the mounting box 2.

[0025] See Figure 1 The crushing assembly includes a crushing box 3 set on the top of the mounting box 2. A rotating motor 4 is fixedly installed on the outer side of the crushing box 3. A crushing roller 6 is rotatably installed inside the crushing box 3. The output shaft of the rotating motor 4 is connected to the crushing roller 6. A feeding protective cover 5 is fixedly installed on the top of the crushing box 3. The feeding protective cover 5 is connected to the inside of the crushing box 3.

[0026] It should be noted that both crushing rollers 6 extend to the outside of the crushing chamber 3 at the same end, and are coaxially fixed with meshing transmission gears at their ends. The outer end of one crushing roller 6 is rigidly connected to the output shaft of the rotating motor 4 via a coupling, forming the driving roller; the other crushing roller 6 is driven by the driving roller through gear meshing, forming the driven roller. When the rotating motor 4 starts, the driving roller rotates with the output shaft, and its end gear drives the gear of the driven roller to rotate in the opposite direction, ultimately achieving synchronous operation of the two crushing rollers 6 at the same speed but in opposite directions. This is existing technology and will not be described in detail here.

[0027] The system consists of two shredding rollers 6, one of which is driven by a rotating motor 4. The two shredding rollers 6 are in contact with each other, while the shredding roller 6 not connected to the rotating motor 4 rotates through a transmission mechanism. Documents are fed between the two shredding rollers 6 for shredding. The staff can feed the documents to be shredded from the feeding protective cover 5, start the rotating motor 4, and drive the shredding roller 6 to rotate. The shredding roller 6 crushes the documents, and the shredded waste paper falls into the collection box 9.

[0028] See Figure 5 The top of the base 1 is provided with a guide groove 19, and the bottom outer side of the turntable 7 is fixedly connected with a limit block, which is slidably connected to the guide groove 19.

[0029] By setting the guide groove 19, the limiting block at the bottom of the turntable 7 can slide inside the guide groove 19, which helps to improve the stability of the turntable 7 rotation.

[0030] See Figure 2A rod 12 is fixedly installed on the bottom of the inner wall of the turntable 7, and a limiting groove is opened at the bottom of the collection box 9, and the rod 12 is inserted into the inside of the limiting groove.

[0031] By providing a rod 12 at the bottom of the inner wall of the turntable 7, the bottom limiting groove of the collection box 9 can be aligned with the rod 12 when installing the collection box 9, which facilitates the installation of the collection box 9.

[0032] Working principle: When using the device, the operator can put the documents to be shredded into the feeding protective cover 5, start the rotating motor 4, drive the transmission gear at the end of one of the shredding rollers 6 to rotate, and the transmission gears on one side of the two shredding rollers 6 mesh and rotate, so that the shredding rollers 6 shred the documents. The shredded waste paper falls into the collection box 9. When a large number of documents are shredded, the turntable 7 can be rotated to rotate the collection box 9 located inside the mounting box 2 out of the mounting box 2, and rotate an empty collection box 9 into the mounting box 2, so that the collection box 9 full of shredded documents can be dumped without stopping the shredding rollers 6. When the turntable 7 is rotated, the operator holds the handle 18 with one hand and pulls the handle 18 away from the positioning box 13. When the handle 18 moves, it causes the limiting rod 16 to slide inside the positioning box 13. One end of the limiting rod 16 moves away from the limiting hole 8, and the other hand can then rotate the turntable 7. After releasing the hand holding the handle 18, during the rotation, the other limiting hole 8 rotates to one side of the base 1. Under the force of the return of the telescopic spring 17, the sliding plate 15 slides in the mounting groove 14. The limiting rod 16 moves with the sliding plate 15 and moves closer to the limiting hole 8, thereby inserting into the interior of the limiting hole 8 and limiting the turntable 7 so that the appropriate collection box 9 is located inside the mounting box 2.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
