DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] See also Figures 1-4 , an embodiment of the present invention provides a technical solution: including a processing mechanism 100 and a crushing mechanism 200.

[0042] Specifically, the processing mechanism 100 includes a tank body 101 for accommodating medical waste. The top of the tank body 101 is hingedly connected to a top cover 102 that matches it, and a disinfection component 104 for disinfecting the waste is installed on the top cover 102. A side cover 103 is also hingedly provided on the side wall of the tank body 101, so that the user can open the side cover 103 to take out the crushed medical waste in the tank body 101, and a ridge 105 is also provided on the inner wall of the tank body 101. The setting of the ridge 105 can improve the crushing effect of the medical waste. At the same time, a partition 106 is also installed inside the tank body 101, and a motor 107 for driving the crushing mechanism 200 is also installed between the partition 106 and the bottom of the inner wall of the tank body 101.

[0043] The crushing mechanism 200 includes a crushing blade assembly 201 located on the coupling at the output end of the motor 107 , and a blade assembly 202 is installed on the outer side of the crushing blade assembly 201 .

[0044] Furthermore, the crushing knife group 201 includes a knife shaft 201a connected to the motor 107, and a knife seat 201b is mounted on the outer side of the knife shaft 201a. By relying on the cooperation between the protrusion of the inner wall of the knife seat 201b and the concave part of the outer wall of the knife shaft 201a, the rotation locking between the knife seat 201b and the knife shaft 201a can be achieved, and a locking screw 201c is installed inside the knife shaft 201a, and the top of the locking screw 201c covers the top of the knife seat 201b, thereby achieving the connection and locking between the knife shaft 201a and the knife seat 201b.

[0045] The blade group 202 includes an upper blade 202a, an intermediate blade 202b and a lower blade 202c distributed in sequence from top to bottom along the axial direction of the blade seat 201b, and the upper blade 202a, the intermediate blade 202b and the lower blade 202c are all radially inserted into the inside of the blade seat 201b along the blade seat 201b. At the same time, the upper blade 202a, the intermediate blade 202b and the lower blade 202c are all symmetrically arranged with respect to the blade seat 201b, wherein the upper blade 202a and the lower blade 202c are arranged in the same orientation, and the intermediate blade 202b is staggered relative to the upper blade 202a and the lower blade 202c. At the same time, the upper blade 202a is arranged perpendicular to the blade seat 201b, while the intermediate blade 202b and the lower blade 202c are arranged in a relatively horizontal posture. Through the different positions and posture settings of the blades, the crushing effect of the crushing mechanism 200 on medical waste is guaranteed.

[0046] During use, medical waste is placed in the tank body 101, and the top cover 102 and the side cover 103 are closed, and the motor 107 and the disinfection component 104 are started. The motor 107 drives the crushing knife group 201 to rotate. At this time, the blade group 202 contacts the medical waste and cuts and crushes it. At the same time, the disinfection component 104 generates high temperature and cooperates with the heat generated by the friction with the waste during the crushing movement of the crushing knife group 201 to achieve high-temperature sterilization and disinfection of medical waste, and achieve harmless treatment of medical waste to avoid the spread of pathogens in subsequent processing and discharge processes, improve the operating safety of operators, and avoid pollution to the environment.

[0047] See also Figures 1-7 , an embodiment of the present invention provides a technical solution: the crushing mechanism 200 further includes a locking member 203 and an adjusting member 204 .

[0048] Specifically, the locking member 203 is installed inside the crushing blade assembly 201 , and an adjusting member 204 is further provided on the outer side of the locking member 203 .

[0049] The locking member 203 includes a rotating ring 203a located inside the knife seat 201b, and a positioning screw 203b passes through the interior of the rotating ring 203a, and the positioning screw 203b and the rotating ring 203a are movably connected. The positioning screw 203b can be locked with the rotating ring 203a through the convex edge on its upper part, so that the rotating ring 203a can perform synchronous axial movement with the positioning screw 203b. The outer side of the rotating ring 203a is movably connected to the lifting sleeve 203c, and positioning plates 203d are fixed on both sides of the outer wall of the lifting sleeve 203c, and positioning heads 203e are fixed on the bottom of the positioning plates 203d.

[0050] The adjusting member 204 includes brackets 204a fixed on the outer walls of both sides of the lifting sleeve 203c. The outer sides of the brackets 204a are hingedly provided with movable buckle plates 204b, and the bottom surfaces of the movable buckle plates 204b are fixedly provided with limit buckles 204c.

[0051] Furthermore, a positioning hole 202d is left on one end of the upper blade 202a, the middle blade 202b and the lower blade 202c located inside the blade holder 201b. The positioning holes 202d on the upper blade 202a and the lower blade 202c cooperate with the positioning head 203e, and the positioning hole 202d on the middle blade 202b cooperates with the limiting buckle 204c. Therefore, under the cooperation of the positioning buckle and the positioning head 203e or the limiting buckle 204c, when the lifting sleeve 203c drives the positioning plate 203d and the movable buckle plate 204b to move up and down, the blade assembly 202 can be unlocked or locked as a whole. This arrangement can realize the separate replacement of the blade on one side without disassembling the crushing knife assembly 201. While facilitating the replacement of the blade, it reduces the cost of replacing the entire blade due to wear on one side, and ensures the stability of the blade assembly 202 during the rotation of the crushing knife assembly 201.

[0052] An adjustment hole 201e that is threadedly engaged with the positioning screw 203b is provided on the top of the knife holder 201b. When the positioning screw 203b is screwed into the adjusting hole 201e, the position of the lifting sleeve 203c can be fixed by rotating the ring 203a, thereby ensuring stable cooperation between the positioning head 203e or the limiting buckle 204c and each positioning port 202d. At the same time, by rotating the positioning screw 203b, the lifting sleeve 203c can be driven to move upward, thereby allowing the positioning head 203e or the limiting buckle 204c to move out of the corresponding positioning port 202d, thereby releasing the lock on each blade. The user can now replace the severely worn blade.

[0053] During use, when the user observes that the blade at a certain position is severely worn, the user can rotate the positioning screw 203b to screw it out of the adjustment hole 201e. As the positioning screw 203b is screwed out, the rotating ring 203a moves up synchronously, thereby driving the lifting sleeve 203c to rise, thereby causing the positioning head 203e and the limit buckle 204c at each position to disengage from the corresponding positioning port 202d. At this time, each blade is in an unlocked state, and the user can replace the severely worn blade by directly pulling out the blade at the corresponding position and directly inserting the intact blade. It is convenient and quick. After the replacement is completed, the positioning screw 203b is screwed back into the adjustment hole 201e to complete the re-locking of the blade group 202.

[0054] In summary, by adopting a split and independent setting of the blade and cooperating with the locking member 203, the independent disassembly and replacement of the blade on one side can be achieved. Compared with the traditional integrated blade, after a single blade on one side is worn and aged, there is no need to replace the entire layer of blades, which reduces the cost of using the blades. At the same time, under the setting of the locking member 203, the blade can be unlocked and locked only by the positioning screw 203b, without the need to disassemble the entire crushing knife group 201, making the replacement of the blade more convenient and quick.

[0055] See also Figures 1-9 In another embodiment provided by the present invention, an adjusting member 204 and a closing member 205 are included.

[0056] Specifically, two adjustment cavities 201d are symmetrically provided inside the blade holder 201b, and adjustment members 204 are installed inside the two adjustment cavities 201d.

[0057] The adjusting member 204 further includes a supporting plate 204d movably mounted inside the adjusting cavity 201d, and a traction rod 204e is fixed to one end of the supporting plate 204d and the movable buckle plate 204b. At the same time, the two traction rods 204e are both passed through the opening 203g opened on the outer wall of the lifting sleeve 203c.

[0058] Furthermore, two adjustment slots 203f are provided on the outer wall of the rotating ring 203a. The two adjustment slots 203f are arranged parallel to each other, and the traction rods 204e at the ends of the supporting plate 204d and the movable buckle plate 204b extend into the two adjustment slots 203f respectively.

[0059] Preferably, the adjustment slot 203f is inclined along the outer wall of the rotating ring 203a, and the traction rod 204e is in sliding fit with the adjustment slot 203f, so that when the rotating ring 203a rotates, the groove wall of the adjustment slot 203f can generate a driving force on the traction rod 204e. Under the relative movement between the adjustment slot 203f and the traction rod 204e, the traction rod 204e is prompted to swing in the vertical direction, thereby changing the angle between the supporting plate 204d and the movable buckle plate 204b, thereby achieving the purpose of adjusting the angle of the middle blade 202b, so that the user can optimize the blade angle in real time according to the crushing state. At the same time, the adjustment holes 201e are arranged in an equidistant annular array on the knife seat 201b, so that after the rotating ring 203a rotates, the positioning screw 203b can be connected with the corresponding adjustment hole 201e to achieve the fixation of the rotating ring 203a at different rotation angles.

[0060] The closing member 205 includes closing plates 205a located on both sides of the middle blade 202b. Connecting blocks 205b are fixed on both sides of the two closing plates 205a, and the connecting blocks 205b are embedded in the outer wall of the knife holder 201b to ensure a stable connection between the closing plates 205a and the knife holder 201b. At the same time, support springs 205c are installed between the end of the connecting block 205b and the outer wall of the knife holder 201b to ensure that the closing plate 205a can always be in contact with the middle blade 202b to prevent waste from entering the adjustment chamber 201d during the crushing process.

[0061] During use, the user can unscrew the positioning screw 203b, and then rotate the rotating ring 203a, and with the help of the adjustment slot 203f and the traction rod 204e, the angle of the middle blade 202b can be adjusted. After the adjustment is completed, the positioning screw 203b is reconnected with the corresponding position adjustment hole 201e to complete the locking of the rotating ring 203a. At this time, the angle of the middle blade 202b is adjusted and locked. At the same time, the closing plate 205a can always maintain contact with the middle blade 202b as the angle of the middle blade 202b is adjusted, so as to avoid the seal between the blade and the blade seat 201b being exposed and causing waste to enter the adjustment cavity 201d.

[0062] In summary, through the cooperation between the adjusting member 204 and the adjusting slot 203f, the angle between the middle blade 202b and the other two adjacent blades can be adjusted. Therefore, the user can adjust the angle of the middle blade 202b according to the different crushing states of the waste to optimize the crushing effect and improve the crushing efficiency.

[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
