DETAILED DESCRIPTION

[0023] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] like Figure 1-Figure 5 A surgical waste treatment device shown in the figure includes a treatment box 10, a knife roller assembly and a driving assembly. The treatment box 10 is provided with a treatment chamber 11, an inlet 12 and an outlet 13, and the inlet 12 and the outlet 13 are both connected to the treatment chamber 11. The inlet 12 is set at the top of the treatment chamber 11, and the outlet 13 can be set at the bottom side of the treatment chamber 11.

[0027] Specifically, the knife roller assembly includes a transmission shaft 21, a plurality of first blades 22, and a plurality of second blades 23, and the plurality of first blades 22 are all mounted outside the transmission shaft 21, and the plurality of first blades 22 are arranged at intervals on the transmission shaft 21. In addition, the first blade 22 includes a plurality of first blade portions 221, and the plurality of first blade portions 221 are distributed at intervals around the central axis of the transmission shaft 21, and a plurality of second blades 23 are arranged between the first blade portions 221 corresponding to two adjacent first blades 22.

[0028] On the basis of the above structure, when using the surgical waste treatment device of the present invention, the waste can be placed into the treatment chamber 11 of the treatment box 10 through the inlet 12 at the top, and then the driving component is started to drive the transmission shaft 21 to rotate. The rotation of the transmission shaft 21 can drive the multiple first blades 22 to rotate, and the multiple first blades 22 can crush the waste introduced by the inlet 12.

[0029] Since there is a gap between the first blades 22 and the first blades 22, the waste is easily crushed in a dead angle at the position between the two first blades 22. In this embodiment, multiple second blades 23 are arranged between the first blade portions 221 of the two first blades 22. The multiple second blades 23 can cut and disperse the waste at the cutting position of the first blade 22, which can reduce the accumulation of waste between two adjacent first blades 22, and the crushing is more complete and the effect is better.

[0030] In addition, each first blade 22 has a plurality of first blade portions 221 in the circumferential direction. When rotating one circle, different first blade portions 221 can perform cutting in sequence to achieve sufficient cutting.

[0031] Furthermore, two adjacent first blade portions 221 on the same first blade 22 are connected by an arc segment. If the two adjacent first blade portions 221 are connected by a straight line segment, it is easy for materials to get stuck between the two first blade portions 221. Therefore, in the present embodiment, two adjacent first blade portions 221 are connected by an arc segment. In this way, during the rotation of the first blade 22, the arc segment can easily guide the material between the two first blade portions 221 to be thrown out under the action of centrifugal force, and it is not easy to get stuck.

[0032] Furthermore, in order to facilitate the assembly of multiple second blades 23 between the first blade portions 221 of two first blades 22, a connecting rod can be provided between two adjacent first blade portions 221 in the axial direction of the blade shaft, and the multiple second blades 23 can be mounted on the connecting rod and can rotate relative to the connecting rod.

[0033] Based on this structure, when cutting waste, multiple second blades 23 can be used to cut at intervals between two first blades 22, and the multiple second blades 23 can rotate relative to the connecting rod. Therefore, during the rotation of the transmission shaft 21, the second blades 23 can swing relative to the connecting rod, and during the swinging process, the cut waste is thrown away and separated, thereby reducing the situation where the waste is stuck between the two second blades 23.

[0034] Furthermore, a support rod 215 can be connected between two adjacent first blade portions 221 in the axial direction of the transmission shaft 21, and the support rod 215 and the connecting rod are staggered. Specifically, since multiple first blades 22 are arranged at intervals on the transmission shaft 21, the first blades 22 are prone to shaking during the cutting process. Therefore, a support rod 215 can be further provided between the axially adjacent first blade portions 221 to connect the axially first blade portions 221 as a whole, thereby reducing the shaking of the first blade portions 221 during the cutting process, so that the first blade portions 221 can cut stably and with stronger cutting force.

[0035] Furthermore, the above-mentioned second blade 23 includes two second blade portions 231, and the two second blade portions 231 are connected by a connecting section 232. The second blade portion 231 is provided with a through hole 233, and the connecting rod is penetrated in the through hole 233. In this way, when the second blade 23 and the connecting rod are assembled, the connecting rod can be assembled into the through hole 233 of one of the second blade portions 231 of the second blade 23, and then when the transmission shaft 21 rotates, the second blade portion 231 can rotate about the rotation axis of the connecting rod, and the second blade portion 231 at the other end can cut during the swinging process.

[0036] Since both second blade portions 231 are provided with connecting holes 233 , during assembly, the connecting rod can be assembled with any second blade portion 231 , and the other second blade portion 231 can then perform cutting without positioning and assembly, making assembly easier.

[0037] Furthermore, an air guide channel 211 and a plurality of air blowing holes 212 may be provided on the transmission shaft 21, and the air guide channel 211 may be extended along the axial direction of the transmission shaft 21, and the plurality of air blowing holes 212 may be connected to the air guide channel 211. Specifically, the air guide channel 211 on the transmission shaft 21 may be connected to an air pipe, and hot air may be introduced into the air guide channel 211 through the air pipe, and the hot air introduced through the air guide channel 211 may be discharged through the plurality of air blowing holes 212, so that waste adhering to the surface of the transmission shaft 21 may be blown away.

[0038] At the same time, the introduced hot air can also heat the inside of the processing chamber 11 and perform preliminary disinfection on the waste gas after crushing, so as to facilitate subsequent further processing.

[0039] Furthermore, the end cover of the transmission shaft 21 is provided with a protective cover 213, and the protective cover 213 is provided with a through hole; the through hole is provided with a protective net 214. The end of the transmission shaft 21 can be protected by the protective cover 213, and the through hole can be used for the air pipe to be introduced, and the protective net 214 can be used for protection at the through hole, which is safer.

[0040] Furthermore, the driving assembly includes a driving motor 24, two synchronous wheels 25 and a synchronous belt. The driving motor 24 is installed at the bottom end of the processing box 10. The rotating shaft of the driving motor 24 is connected to one of the synchronous wheels 25. The end of the transmission shaft 21 is connected to another synchronous wheel 25. The two synchronous wheels 25 are connected by a synchronous belt transmission. In this way, one of the synchronous wheels 25 can be driven to rotate by the rotating shaft of the driving motor 24, and the other synchronous wheel 25 can be driven by the synchronous belt, thereby driving the transmission shaft 21 to rotate, and then driving the multiple first blades 22 to rotate, so that the cutting process of the multiple first blades 22 and the multiple second blades 23 is stable.

[0041] Furthermore, a guide plate is provided at the bottom of the processing chamber 11, and the guide plate is gradually inclined from top to bottom toward the guide outlet 13, so that the crushed waste can be guided to be discharged through the inclined guide plate, and the discharge is more convenient.

[0042] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
