The structure of the crushing mechanism generally includes a drive motor arranged outside the barrel and a crushing blade arranged at the end of the drive shaft of the drive motor and located inside the barrel.

[0003] Since many of the materials to be crushed, such as medical solid waste, include long and tough materials such as zippers, gauze, and bed sheets, traditional solid waste crushing equipment is prone to problems such as being unable to cut the materials, causing them to rotate with the barrel or get entangled with the blade.

[0004] In view of this, the applicant has invented a new type of crushing structure that can effectively cut materials with longer size and higher toughness and is less likely to cause the problem of blade entanglement. Summary of the Invention

The drive shaft of the turntable drive motor passes through the bottom of the barrel body and is connected to the isolation turntable from the outside. When the rotating blade rotates past the shearing blade, it approaches the shearing blade to form a shear force to crush the material in the barrel.

[0008] As a further improvement, a plurality of isolation blades are further provided at the bottom of the turntable body, and the isolation blades are extended from the axis of the drive shaft of the turntable drive motor to the outer edge of the turntable body.

[0011] As a further improvement, the included angle between the blade unit and the fixed plate is 90°, and the number of blade units on each of the rotating blades or the shearing blades is at least three.

[0012] As a further improvement, the number of the rotating blades is two, and the two rotating blades are arranged along the diameter direction of the isolation turntable, and the outermost blade unit of the rotating blade is located at the outer edge of the isolation turntable; the number of the shearing blades is three, and the three shearing blades are evenly arranged in the vertical direction, and one of the blade units of each shearing blade is at the same height as the blade unit of the rotating blade.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of this patent, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0027] Please refer to Figures 1 to 3 A novel pulverizing structure includes a barrel body 10 and a pulverizing mechanism 20; the pulverizing mechanism 20 includes a turntable drive motor 30 and a pulverizing blade assembly 21 disposed at the bottom of the barrel body 10; the pulverizing blade assembly 21 includes an isolation turntable 22 disposed above the inner bottom surface of the barrel body 10, a rotating blade 211 disposed on the isolation turntable 22, and a shearing blade 212 disposed on the inner side of the barrel body 10. The drive shaft of the turntable drive motor 30 passes through the bottom of the barrel body 10 and is connected to the isolation turntable 22. When the rotating blade 211 rotates past the shearing blade 212, it approaches the shearing blade 212 to generate a shear force to pulverize the material in the barrel. In this embodiment, the turntable drive motor 30 is driven by a belt.

[0028] The overall structure of the rotating blade 211 cooperating with the shear blade 212 allows the rotating blade 211 to approach the shear blade 212 when rotating past the shear blade 212 to form an instantaneous shear force to effectively cut and crush the longer and more tough materials wrapped around the rotating blade 211, thereby avoiding the problem of blade entanglement.

[0029] Please refer to Figure 3The bottom of the turntable body 221 is further provided with a plurality of isolation blades 23, which extend from the axis of the drive shaft of the turntable drive motor 30 toward the outer edge of the turntable body 221. Since there is a gap between the turntable body 221 and the bottom of the barrel body 10 to prevent direct friction between the two, the drive shaft of the turntable drive motor 30 is exposed below the turntable body 221. The crushed solid waste can easily approach the drive shaft during high-speed rotation, causing problems such as blade entanglement or damage to the drive shaft. Therefore, the high-speed centrifugal force generated by the high-speed rotation of the isolation blades 23 can be used to throw the crushed materials under the turntable body 221 along the inclined surface of the blades. The isolation effect generated by the high-speed rotation of the outer edge of the isolation blades 23 can further prevent the crushed materials in the barrel from entering the bottom of the turntable body 221.

[0030] Please refer to Figure 1 and Figure 2 The rotating blade 211 and the shearing blade 212 include a plurality of blade units 24, each having a chamfered outer edge to form a cutting edge. The cutting edges of the plurality of blade units 24 effectively generate multiple transverse cutting and shearing forces within the barrel, ensuring that materials at all locations within the barrel are quickly crushed.

[0031] Furthermore, the rotating blade 211 and the shearing blade 212 further include a fixed plate 25, the blade unit 24 is fixed on the fixed plate 25, and the fixed plate 25 is fixed to the isolation turntable 22 in a detachable manner such as bolts. The rotating blade 211 and the shearing blade 212 are both fork-shaped, and the blade unit 24 is triangular in shape, defining the angle between the blade unit 24 and the fixed plate 25 to be in the range of 60° to 120°.

[0032] The knife-and-fork-shaped rotating blade 211 and the shearing blade 212 can effectively form a combined blade with strong shearing force, ensuring that the overall cutting force is sufficient. At the same time, by controlling the angle thereof, it can effectively ensure that each blade unit 24 produces a larger spatial shearing effect when rotating.

[0033] Preferably, the angle between the blade units 24 and the fixed plate 25 is 90°, and each rotating blade 211 or shear blade 212 includes at least three blade units 24. Specifically, the rotating blade 211 includes several vertically upward cutting edges, with the outer cutting edges located at the outer edge of the turntable body 221. The shear blade 212 includes several horizontally arranged cutting edges, with the bottommost cutting edge positioned adjacent to the cutting edge of the rotating blade 211. The vertical angled arrangement of the blade units 24 effectively ensures the most direct and powerful shear force on the bottom and sides of the material during rotation, improving overall crushing efficiency.

[0034] Please refer to Figure 2There are two rotating blades 211, each arranged along the diameter of the isolation disc 22. The rotating blades 211 are detachably fixed to the isolation disc 22 via bolts, with the outermost blade units 24 of the rotating blades 211 located at the outer edge of the isolation disc 22. There are three shearing blades 212, each evenly spaced vertically. One blade unit 24 of each shearing blade 212 is at the same height as the blade unit 24 of the rotating blade 211. The mutually perpendicular arrangement of the blade units 24, combined with the equal height setting, creates the most suitable shearing space and the most effective shearing force during rotation, achieving the best pulling and crushing effect on the material.

[0035] Please refer to Figure 1 , several microwave generators 40 are further provided on the outside of the outer barrel. In this embodiment, the pulverizing mechanism 20 can be used in microwave processing equipment. The material to be processed is medical solid waste, so it needs to be sterilized by microwaves and steam. The isolation turntable 22 includes a turntable body 221 and at least one wave-transparent member 222 fixedly provided on the turntable body 221. The wave-transparent member 222 can be semicircular, quarter-circular or annular; a wave-transparent port is provided on the turntable body 221, which is opposite to the wave-transparent member 222. The material of the wave-transparent member 222 is polyamide-imide, polyimide, Teflon or borosilicate.

[0036] Preferably, the number of the wave-transparent members 222 is four, and the wave-transparent members 222 are in the shape of a quarter circle. The four wave-transparent members 222 are symmetrically distributed around the center. The wave-transparent openings provided on the turntable body 221 are also four quarter-circular openings. The bottom of each wave-transparent opening further extends horizontally inward to provide a support portion. The wave-transparent member can be limitedly placed on the support portion, and the wave-transparent member 222 can be detachably fixed to the support portion through a number of quarter-circular ring-shaped pressing pieces 223 in conjunction with bolts. On the one hand, this ensures the stable fixed installation of the wave-transparent member 222 and improves its service life. On the other hand, a single or multiple wave-transparent members 222 can be replaced individually after being worn or damaged, thereby effectively reducing the overall cost of use.

[0037] Please refer to Figure 1 The number of the microwave generators 40 is at least four, and the microwave generators 40 are distributed on the outer wall of the barrel body 10; through multiple evenly arranged microwave generators 40, it can be effectively ensured that the processing space in the barrel is evenly heated.

[0038] Its microwave generator 40 is existing technology and is composed of multiple microwave heating components, including a microwave switching power supply, a magnetron, a rectangular waveguide, etc. It can be purchased directly on platforms such as 1688 by searching for keywords such as related industrial microwave drying equipment components or industrial microwave heating equipment components. I will not go into details here.

[0039] By adopting a structure in which the wave-transparent member 222 is combined with the microwave generator 40, the material selection of the wave-transparent member 222 can effectively ensure that the microwaves can pass through the wave-transparent member 222 to heat and disinfect the bottom of the turntable body 221, and the microwaves can also be enhanced by the reflection of the bottom metal. At the same time, the wave-transparent member 222 can be supported and fixed by the turntable body 221. The structural design is ingenious and the function is easy to implement.

[0040] Please refer to Figure 2 The shredding blade assembly 21 further includes a blade disassembly plate 213 mounted on the isolation turntable 22 and arranged along the diameter of the isolation turntable 22, and a plurality of shredding blades 214 mounted on the blade disassembly plate 213. The blade disassembly plate 213 is removably secured to the isolation turntable 22 by means of bolts. The shredding blades 214 can be completely disassembled by disassembling the blade disassembly plate 213, allowing for quick subsequent maintenance of the isolation turntable 22. This avoids the need to individually disassemble the shredding blades 214 and other blades that may be secured to the blade disassembly plate 213, effectively improving overall installation efficiency.

[0041] Furthermore, the cutting edges of the crushing blades 214 are arranged horizontally, and there are at least two crushing blades 214 arranged along the diameter of the isolation turntable 22. The horizontal cutting edges of the crushing blades 214 can effectively generate a cutting force on the horizontal plane, cooperating with the shear blades 212 and the rotating blades 211 to more thoroughly crush the material.

[0042] Please refer to Figure 3 The four isolation blades 23 are triangular prism-shaped and are symmetrically arranged. They extend obliquely from the center of the drive shaft to the outer edge of the turntable body 221. The extension direction is not in the same direction as the radius to maximize the length of the isolation blades 23, thereby forming a larger rotating isolation ring to prevent the crushed material from entering the rotating shaft.

[0043] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.

Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
