[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 4 , this embodiment provides a crushing device, which is mainly used for crushing paper documents to achieve the purpose of confidentiality, including: first support 1, crusher main body 2, feeding mechanism 3 for feeding, dust suction mechanism 4 for sucking dust, filtering mechanism 5 for filtering dust, and support 6 for supporting the dust suction mechanism 4. The crusher main body 2 is installed on the top of the first support 1, the feeding mechanism 3 is arranged on one side of the crusher main body 2, the dust suction mechanism 4 is arranged on the top of the crusher main body 2, the filtering mechanism 5 is arranged on the dust suction mechanism 4, the support 6 is fixedly connected to the top of the first support 1, and the filtering mechanism 5 is located in the inner cavity of the support 6; the dust suction mechanism 4 includes a cover 41 movably arranged at the feeding port of the crusher main body 2 through an automatic opening and closing mechanism. The top of the cover 41 is communicated with a hose 42, the other end of the hose 42 is communicated with a middle pipe 43, the top of the inner cavity of the middle pipe 43 is provided with an upper pipe 44, the inner cavity of the upper pipe 44 is fixedly connected with a second support 45, a biaxial motor 46 is installed inside the second support 45, one of the output shafts of the biaxial motor 46 is fixedly connected with a fan blade 47, and the support 6 is fixedly connected to the outer surface of the middle pipe 43.

[0026] It should be noted that the above automatic opening and closing mechanism can adopt a box cover automatic opening and closing mechanism disclosed in the existing publication number CN106401352B, which can realize the automatic opening and closing of the cover 41. It is prior art, so no more details will be described in this technology.

[0027] Among them, the feeding mechanism 3 includes a mounting seat 31 fixedly connected to one side of the crusher main body 2. A lifting member 32 is vertically provided on the top of the mounting seat 31, and a feeding member 33 is installed on one side of the lifting member 32.

[0028] It should also be noted that the working principles of the above-mentioned crusher main body 2, lifting member 32, and feeding member 33 are the same as those of the crushing chamber, lifting assembly, and feeding trough in a particle crusher disclosed in the prior art with the publication number CN221182901U. They are prior art, so no further elaboration will be made in this technology.

[0029] Among them, a rodless cylinder 34 is horizontally installed on the top of the mounting seat 31. The top of the slide of the rodless cylinder 34 is fixedly connected to the bottom of the lifting member 32. By starting the rodless cylinder 34, the lifting member 32 and the feeding member 33 can be driven to move horizontally synchronously, thereby providing a moving space for the opening and closing operation of the cover 41.

[0030] Among them, a protective cover 48 is fixedly connected to the top of the inner cavity of the upper pipe 44. The protective cover 48 is located above the fan blade 47. The protective cover 48 can play a protective role for the fan blade 47 to improve the safety when the fan blade 47 rotates.

[0031] Among them, the filtering mechanism 5 includes a first filter screen 51 installed in the inner cavity of the middle pipe 43. The first filter screen 51 is located above the air inlet of the middle pipe 43. A lower cylinder 52 is threadedly connected to the lower surface of the outer surface of the middle pipe 43. The lower cylinder 52 is located in the inner cavity of the support 6. The first filter screen 51 can filter the sucked dust, so that the dust remains below the first filter screen 51. The dust can fall into the inner cavity of the lower cylinder 52 by its own gravity for unified collection. By connecting the lower cylinder 52 and the middle pipe 43 by thread, it is convenient for the subsequent loading and unloading of the lower cylinder 52 for dust dumping operations.

[0032] Among them, the lower cylinder 52 is a transparent dust collection cylinder, so that the staff can intuitively understand the dust collection situation inside the lower cylinder 52 for timely dust dumping operations.

[0033] Among them, another output shaft of the double-shaft motor 46 is fixedly connected to a rotating rod 53. The bottom end of the rotating rod 53 movably penetrates below the first filter screen 51 and is fixedly connected to a brush 54. The bristles on the top of the brush 54 are in contact with the bottom of the first filter screen 51. When the double-shaft motor 46 is started, the rotating rod 53 and the brush 54 can be driven to rotate, thereby cleaning the dust remaining at the bottom of the first filter screen 51, effectively avoiding the phenomenon that the dust always adheres to the bottom of the first filter screen 51 during the dust suction operation and reducing the filtering effect. The double-shaft motor 46 can drive the fan blade 47 and the brush 54 to rotate synchronously, which conforms to the concept of energy saving and power saving.

[0034] Among them, a second filter screen 7 is installed in the inner cavity of the baffle cover 41, and a third filter screen 8 is installed on one side of the main body 2 of the pulverizer. The filter holes of the third filter screen 8 are the same as those of the first filter screen 51 and smaller than those of the second filter screen 7. The second filter screen 7 can effectively block particulate matter, preventing particulate matter from being sucked synchronously with the dust. At the same time, the third filter screen 8 can not only ensure the flow of gas but also prevent the dust from spreading into the surrounding environment.

[0035] The working principle of the present utility model is as follows: Start the rodless cylinder 34. The slide table of the rodless cylinder 34 drives the lifting member 32 and the feeding member 33 to horizontally move towards the feeding port of the main body 2 of the pulverizer until the discharging end of the feeding member 33 moves above the main body 2 of the pulverizer. Then, the paper document material to be pulverized can be fed into the inner cavity of the main body 2 of the pulverizer through the feeding member 33. Then, use the automatic opening and closing mechanism to close the baffle cover 41 on the top of the main body 2 of the pulverizer. Start the main body 2 of the pulverizer to perform the pulverization operation on the paper document material. Start the double-shaft motor 46. One output shaft of the double-shaft motor 46 drives the fan blade 47 to rotate, so that the dust generated by pulverization in the main body 2 of the pulverizer can be sucked into the inner cavity of the baffle cover 41 through the second filter screen 7, and then conveyed to the inner cavity of the middle pipe 43 through the hose 42. After being filtered by the first filter screen 51, the gas is discharged from the top end of the upper pipe 44, and the dust remains at the bottom of the first filter screen 51. The other output shaft of the double-shaft motor 46 drives the rotating rod 53 and the brush 54 to rotate synchronously. The brush 54 performs a cleaning operation on the dust at the bottom of the first filter screen 51 to avoid a large amount of dust adhering to the bottom of the first filter screen 51 for subsequent filtering operations. After the dust collection is completed, by rotating the lower cylinder 52, the lower cylinder 52 can be removed from the middle pipe 43, so that the dust accumulated in the lower cylinder 52 can be dumped.

[0036] Parts not involved in the present utility model are the same as or can be implemented by using the prior art. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
