Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment, and in particular to a grinding and pulverizing blade with good grinding effect and a kitchen waste treatment device using the blade. Background Technology

[0002] With the continuous acceleration of urbanization, how to efficiently handle kitchen waste has become an urgent problem to be solved. Traditional kitchen waste treatment methods, such as landfill and incineration, face many problems such as environmental pollution and resource waste. Therefore, developing and promoting more environmentally friendly and efficient kitchen waste treatment equipment, especially kitchen waste treatment equipment that can achieve efficient treatment and resource utilization, has become an important direction of technological development.

[0003] Existing food waste processing equipment mainly uses mechanical mixing blades to chop food waste for subsequent processing. Typically, the mixing blades in food waste processing equipment use a rotary cutting method to physically crush food waste, achieving a certain chopping effect. The design principle and structure of these blades enable them to cut large pieces of food waste into smaller pieces to facilitate further processing and resource utilization. However, these existing mixing blades only have chopping and mixing functions and lack sufficient grinding capabilities.

[0004] Specifically, while existing mixing blades can break large pieces of food waste into smaller pieces during the chopping process, the chopped material often retains a relatively large size because the blades primarily function to cut and mix. This larger size not only affects subsequent processing efficiency but also increases the difficulty of equipment cleaning and maintenance. In some applications requiring finer crushing and grinding, the existing mixing blade design is clearly inadequate, leading to limitations in processing effectiveness. For example, for kitchen waste containing a lot of moisture or that is relatively hard (such as bones, nut shells, etc.), existing mixing blades may not be able to effectively further refine it into sufficiently small particles, thus affecting the efficiency of subsequent processing steps (such as drying, fermentation, composting, or biodegradation).

[0005] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0006] The aforementioned technical problem is that the mixing blades in existing food waste processing equipment only have chopping and mixing functions and lack sufficient grinding capabilities.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A grinding and pulverizing tool with good grinding effect includes a rotating cutter shaft rotatably connected inside a mixing housing and a pulverizing auxiliary cutter disposed on the inner wall of the mixing housing. The pulverizing auxiliary cutter includes an auxiliary cutter connecting section disposed on the inner wall of the mixing housing and a first auxiliary cutter disposed on one side of the auxiliary cutter connecting section. A pulverizing main cutter is disposed on the rotating cutter shaft. The first auxiliary cutter and the pulverizing main cutter are arranged in an upper and lower layer, and there is a grinding gap between them. Both the first auxiliary cutter and the pulverizing main cutter are provided with cutting edges on their side walls. When the rotating cutter shaft rotates and drives the pulverizing main cutter to rotate to the position of the first auxiliary cutter, the pulverizing main cutter and the first auxiliary cutter can perform a cutting action on the material through the cutting edges, and the pulverizing main cutter and the first auxiliary cutter can perform a grinding action on the material through the grinding gap.

[0009] As described above, a grinding and pulverizing tool with good grinding effect includes a mixing arm and a first main blade, with the two ends of the mixing arm connected to the first main blade and a rotating blade shaft, respectively.

[0010] As described above, a mixing and pulverizing tool with good grinding effect has multiple first auxiliary blades, which are spaced apart from top to bottom along the auxiliary blade connecting section. There are also multiple first main blades, each of which is located between two adjacent first auxiliary blades.

[0011] As described above, a mixing and pulverizing tool with good grinding effect has multiple first main blades arranged circumferentially along a rotating blade shaft, and the multiple first main blades are arranged sequentially from bottom to top along the axial direction of the rotating blade shaft.

[0012] As described above, a grinding and pulverizing blade with good grinding effect includes a second main blade in each main blade. The second main blade is located above the corresponding first main blade, and there is a grinding space between them. When the main blade rotates to the first auxiliary blade, the corresponding first auxiliary blade can move into the grinding space, and the top of the first auxiliary blade can form a grinding gap with the bottom of the second main blade, and the bottom of the first auxiliary blade can form a grinding gap with the top of the first main blade.

[0013] As described above, in a grinding and pulverizing tool with good grinding effect, the pulverizing secondary blade also includes a second secondary blade, the bottom of which can form a grinding gap with the top of the second main blade of the pulverizing primary blade located at the highest point.

[0014] As described above, a mixing and pulverizing tool with good grinding effect has multiple pulverizing secondary blades, and the multiple pulverizing secondary blades are arranged at intervals along the circumferential direction of the inner wall of the mixing shell.

[0015] As described above, a mixing and pulverizing tool with good grinding effect includes a rotating cutter shaft comprising a cutter shaft body and a feeding assembly disposed on the cutter shaft body. The feeding assembly can transport the material in the mixing shell to the top of the cutter shaft body and then throw it out.

[0016] The grinding and pulverizing tool with good grinding effect as described above includes a feeding assembly comprising a spiral channel disposed on the outer wall of the cutter shaft body.

[0017] A food waste processing device includes a mixing housing and mixing and pulverizing blades as described in any of the above.

[0018] The beneficial effects of this utility model are:

[0019] This utility model relates to a grinding and pulverizing blade with good grinding effect and a kitchen waste treatment device using the blade, relating to the technical field of kitchen waste treatment. The grinding and pulverizing blade includes a rotating blade shaft and a secondary pulverizing blade. The rotating blade shaft is equipped with a primary pulverizing blade. When the rotating blade shaft drives the primary pulverizing blade to rotate, it can mix and initially chop the material, breaking down larger kitchen waste into smaller pieces. The relative movement between the primary pulverizing blade and the secondary blade, through the contact of their blades, achieves the chopping action of the material. Furthermore, there is a grinding gap between the primary pulverizing blade and the secondary blade. The grinding gap allows the material to be further squeezed and rubbed between the primary pulverizing blade and the secondary blade after chopping, thereby achieving fine grinding of the material. This grinding process can not only further refine the size of the material, but also improve the material processing efficiency. It has significant advantages, especially for materials with high moisture content or difficult to cut (such as nut shells, bones, etc.), which can greatly reduce the size of the material and improve the efficiency of subsequent processing (such as composting or biodegradation).

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown, this embodiment of a grinding and pulverizing tool with good grinding effect includes a rotating blade shaft 2 rotatably connected to a mixing housing 1 and a pulverizing auxiliary blade 3 disposed on the inner wall of the mixing housing 1. The pulverizing auxiliary blade 3 includes an auxiliary blade connecting section 31 disposed on the inner wall of the mixing housing 1 and a first auxiliary blade 32 disposed on one side of the auxiliary blade connecting section 31. A pulverizing main blade 4 is disposed on the rotating blade shaft 2. The first auxiliary blade 32 and the pulverizing main blade 4 are arranged in an upper and lower layer, and there is a grinding gap 5 between them. Both the first auxiliary blade 32 and the pulverizing main blade 4 have cutting edges on their side walls. When the rotating blade shaft 2 rotates and drives the pulverizing main blade 4 to rotate to the position of the first auxiliary blade 32, the pulverizing main blade 4 and the first auxiliary blade 32 can perform a cutting action on the material through the cutting edges, and the pulverizing main blade 4 and the first auxiliary blade 32 can perform a grinding action on the material through the grinding gap 5.

[0029] Specifically, when the rotating blade shaft 2 drives the main crushing blade 4 to rotate, it can stir and initially chop the material, breaking down larger kitchen waste into smaller pieces. The relative movement between the main crushing blade 4 and the first auxiliary blade 32, through the contact of their blades, achieves the chopping action. Especially when the rotating blade shaft 2 rotates, driving the main crushing blade 4 to the position of the first auxiliary blade 32, the contact of their blades can effectively cut the material into even smaller pieces, avoiding the limitations of traditional blades that only perform single-step chopping.

[0030] Furthermore, there is a certain gap between the main crushing blade 4 and the first auxiliary blade 32 to form a grinding gap 5. The grinding gap allows the material to be further squeezed and rubbed between the main crushing blade 4 and the first auxiliary blade 32 after being shredded, thereby achieving fine grinding of the material. This grinding process can not only further refine the size of the material, but also improve the processing efficiency of the material. It has a significant advantage, especially for materials with high moisture content or that are difficult to cut (such as nut shells, bones, etc.), which can greatly reduce the size of the material and improve the efficiency of subsequent processing (such as composting or biodegradation).

[0031] This design integrates three functions through a single cutting tool system, making the equipment's workflow more compact and efficient. Traditional equipment can usually only perform the chopping function and cannot simultaneously perform grinding. However, this equipment design can refine materials while chopping, making it suitable for both coarse processing and applications requiring high-precision crushing.

[0032] Because of the combination of chopping and grinding functions, the chopped material is further refined after entering the grinding gap, and the decomposition process is accelerated. This reduces the potential for material accumulation or processing difficulties in subsequent processes. It is particularly effective when handling complex materials (such as bones and fruit shells), improving processing efficiency. The combined chopping and grinding action between the blades effectively adapts to different types of kitchen waste. Whether it's soft fruit and vegetable waste, hard bones, or dry, hard materials, this blade system can effectively process them, making the equipment highly adaptable to various application scenarios.

[0033] Preferably, the number of the first auxiliary blades 32 is at least one, and the number of the main crushing blades 4 is at least one.

[0034] like Figures 1 to 5 As shown, the main crushing blade 4 in this embodiment includes a stirring arm 41 and a first main blade 42. The two ends of the stirring arm 41 are connected to the first main blade 42 and the rotating blade shaft 2, respectively. Specifically, the function of the stirring arm 41 is to stir the material through rotational motion. When the rotating blade shaft 2 drives the stirring arm 41 to rotate, the stirring arm can stir the material evenly, prevent the material from accumulating or clogging, and ensure that the material can be evenly distributed throughout the entire processing.

[0035] Specifically, the first main blade 42 is connected to the stirring arm 41. While stirring, it can chop the material. When the stirring arm 41 drives the rotating blade shaft 2 to rotate, the first main blade 42 will cut the material, which can cut large pieces of material into smaller pieces. All these chopping functions can effectively reduce the particle size of the material and provide an ideal material size for subsequent grinding.

[0036] After the material is shredded by the first main blade 42, it can be further shredded by the cooperation of the blades of the first secondary blade 32 and the first main blade 42, thus further refining the size of the material.

[0037] Furthermore, while the material is being shredded, it is further subjected to the squeezing and friction between the first secondary blade 32 and the first main blade 42 through the grinding gap 5, resulting in a grinding effect. This fine grinding action can further reduce the particle size of the material and improve processing efficiency.

[0038] Specifically, through the action of the stirring arm 41, the material can be evenly distributed, which helps to prevent material accumulation or stratification, thereby improving the efficiency of the entire processing. The first main blade 42 can cut the material into small pieces, making the material more suitable for subsequent grinding and other processing. For hard materials (such as bones, nut shells, etc.), it can provide a powerful chopping effect. Through the design of the first auxiliary blade 32 and the grinding gap 5, the material is finely ground while being chopped, further reducing the particle size of the material and improving the accuracy and efficiency of subsequent processing.

[0039] This design, through the synergistic action of the stirring arm 41, the first main blade 42, and the first auxiliary blade 32, combines stirring, chopping, and grinding functions into a single cutting tool system, enabling multiple processing of materials and providing higher processing efficiency. Furthermore, through the dual action of chopping and grinding, this cutting tool can precisely adjust the particle size of the material, ensuring that the material reaches the ideal particle size level at different processing stages. This design allows the equipment to maintain high processing accuracy when dealing with different types of materials.

[0040] like Figures 1 to 5 As shown, in this embodiment, there are multiple first auxiliary blades 32, which are spaced apart from top to bottom along the auxiliary blade connecting section 31. There are also multiple first main blades 42, each of which is located between two adjacent first auxiliary blades 32.

[0041] Specifically, multiple first auxiliary blades 32 are spaced apart along the auxiliary blade connecting section 31, and each first main blade 42 is located between two adjacent first auxiliary blades 32. When the rotating blade shaft 2 drives these first main blades 42 to rotate, each main blade will work in conjunction with its adjacent auxiliary blades 32 above and below. Each pair of adjacent first main blades 42 and first auxiliary blades 32 can produce a crushing and grinding effect. In this way, after the material is processed by the combination of multiple main blades and auxiliary blades, it can be cut into finer particles and ground at the same time. This arrangement can ensure that the material is processed evenly during the crushing process, thereby avoiding the situation where some material is not fully processed.

[0042] Due to the cooperation between each primary blade and two secondary blades, the material undergoes multiple stages of cutting and grinding as it passes through these blades. Each stage affects the material, gradually refining its particle size. After passing through the grinding gap between each primary and secondary blade, the material is further subjected to the compression and friction of the blades, refining its particles. This not only ensures the thoroughness of material processing but also optimizes the uniformity of material particles and improves processing efficiency.

[0043] The design of multiple primary blades 32 allows materials to be chopped and ground by multiple blades during processing, with the chopping and grinding effects being evenly distributed. Compared to the traditional single-blade design, this design can refine materials more efficiently, ensuring that every part of the material is fully processed.

[0044] Specifically, multiple primary blades 42 and secondary blades 32 work in parallel, which increases the cutting and grinding effect of the blades and improves the material processing capacity per unit time. The alternating work of multiple primary and secondary blades allows more material to be processed with each rotation, thereby improving the overall processing efficiency.

[0045] Furthermore, the multiple secondary blades spaced apart help to effectively break up the material during processing, preventing the material from accumulating or clogging between the blades due to incomplete chopping or grinding. Each secondary blade can gradually refine and decompose the material, making the material pass through the blades more smoothly.

[0046] The combination design of multiple secondary blades and main blades ensures that the material is processed evenly during the chopping and grinding process. Each secondary blade acts on a different part of the material, which can prevent the material from being over-processed in some parts while other parts are not fully utilized. Through the combination of multiple secondary blades and main blades, the material can be evenly distributed, ensuring that every part of the material is chopped and ground.

[0047] Furthermore, multiple main and auxiliary cutters can share the workload, avoiding excessive cutting or grinding pressure on a single cutter. This design not only extends the service life of the cutters but also reduces the frequency of equipment maintenance. The relatively light load on each cutter helps maintain stable equipment operation.

[0048] like Figures 1 to 5 As shown, in this embodiment, each of the first main blades 42 has a grinding gap 5 between it and the two corresponding first auxiliary blades 32, that is, each of the first main blades 42 has a grinding gap 5 between it and the first auxiliary blades 32 located on its upper and lower sides.

[0049] Specifically, the grinding gap 5 between the first main blade 42 and the adjacent first auxiliary blades 32 is designed as a key processing area when materials pass through. Driven by the rotating blade shaft 2, the blades of the first main blade 42 and the upper and lower auxiliary blades 32 move relative to each other, generating cutting force and grinding force.

[0050] Furthermore, when the material passes through the grinding gap between the first main blade 42 and the two first auxiliary blades 32, it is subjected to the squeezing and friction of the first main blade 42 and the upper and lower first auxiliary blades 32, and the particle size is gradually refined. The material is effectively constrained, ensuring the uniformity of particle size and improving the grinding range and grinding rate.

[0051] Furthermore, the distance between the first main blade 42 and the two first secondary blades 32 is relatively close, which enables the first main blade 42 and the two first secondary blades 32 to chop the food, further improving the chopping effect of the blades.

[0052] like Figures 1 to 5 As shown, in this embodiment, a plurality of first main blades 42 are arranged at intervals along the circumference of the rotating blade shaft 2, and the plurality of first main blades 42 are arranged sequentially from bottom to top along the axial direction of the rotating blade shaft 2.

[0053] Preferably, multiple first main blades 42 are evenly distributed around the circumference of the rotating blade shaft 2 to ensure that the material is cut evenly during the rotation of the blade shaft. This circumferential arrangement allows each main blade to contact the material during rotation, thereby sharing the work of material crushing and grinding, and avoiding excessive wear or overburdening of local blades.

[0054] Furthermore, each primary blade 42 can apply cutting force to the material during rotation. Multiple blades work simultaneously, thereby improving the overall shredding efficiency and ensuring the uniformity of material cutting. The material is fully processed when passing through each blade.

[0055] Furthermore, multiple primary blades 42 are sequentially raised from bottom to top on the rotating cutter shaft 2. As the rotating cutter shaft rotates, the upper primary blade 42 gradually comes into contact with the material, while the lower primary blade 42 is responsible for the initial material crushing. The axially raised arrangement ensures that the material is subjected to different degrees of cutting and grinding as it passes through the primary blades at different heights. This allows the mixing and crushing blades to mix and crush materials at different heights within the mixing housing 1, ensuring that the working range of the mixing and crushing blades can cover the entire material within the mixing housing 1.

[0056] Specifically, multiple primary blades 42 are evenly spaced along the circumference of the rotating blade axis 2, ensuring that the material can be cut and ground multiple times in each rotation of the blade system, which can further uniformly crush the material and improve the overall cutting efficiency.

[0057] Furthermore, the multiple primary blades 42 can cut materials multiple times, which can greatly shorten the processing time, allowing each rotation to effectively process more materials, reducing waiting time and processing cycle.

[0058] like Figures 1 to 5As shown, each of the main crushing blades 4 in this embodiment also includes a second main blade 43. The second main blade 43 is located above the corresponding first main blade 42, and there is a grinding space 44 between them. When the main crushing blade 4 rotates to the first auxiliary blade 32, the corresponding first auxiliary blade 32 can move relative to the grinding space 44, and the top of the first auxiliary blade 32 can form a grinding gap 5 with the bottom of the second main blade 43, and the bottom of the first auxiliary blade 32 can form a grinding gap 5 with the top of the first main blade 42.

[0059] Specifically, each crushing main blade 4 consists of two main blades. The first main blade 42 and the second main blade 43 form a working area that works together through the design of the grinding space 44. When the crushing main blade 4 rotates, the material can be cut by passing through the first main blade 42 and the second main blade 43, achieving double cutting.

[0060] Furthermore, when the main crushing blade 4 rotates to the position of the first auxiliary blade 32, the first auxiliary blade 32 can move relative to the grinding space 44, moving relative to the grinding gap between the first main blade 42 and the second main blade 43. In this way, the cooperation between the first auxiliary blade 32 and the first and second main blades can achieve multi-stage grinding. Moreover, during the relative movement of the first auxiliary blade 32 to the grinding space 44, the first main blade 42 and the second main blade 43 can cooperate with the corresponding first auxiliary blade 32 to achieve multiple cutting.

[0061] Specifically, as the material passes through multiple blade zones, each blade can perform different degrees of chopping or grinding on the material. The multi-stage grinding and cutting design makes material processing more efficient, especially when processing harder materials. The function of each stage ensures that the material particle size is gradually refined, improving the overall work efficiency and enabling the material to be chopped evenly.

[0062] Preferably, the grinding gap 5 can be adjusted according to the type and requirements of the material to adapt to different material particle size requirements. This flexibility further improves the adaptability of the equipment, enabling it to be used in a variety of scenarios. For example, by adjusting the distance between the first auxiliary blades 32, or by adjusting the distance between the first main blade 42 and the second main blade 43 on the stirring arm 41, a suitable design can be selected according to actual needs.

[0063] like Figures 1 to 5 As shown, the pulverizing secondary blade 3 in this embodiment also includes a second secondary blade 33, the bottom of which can form a grinding gap 5 with the top of the second main blade 43 of the pulverizing main blade 4 located at the highest point.

[0064] Specifically, the second auxiliary blade 33 is located in the design of the crushing auxiliary blade 3, usually in the upper part of the system, close to or directly on top of the second main blade 43, which allows the second auxiliary blade 33 to form a precise grinding gap 5 with the second main blade 43.

[0065] After the material is initially cut by the first main blade 42 and the second main blade 43, the bottom of the second auxiliary blade 33 and the top of the second main blade 43 form a grinding gap 5 to further grind the material. In this process, the second auxiliary blade 33 provides additional grinding force through the gap between it and the second main blade 43 to ensure that the material is further refined.

[0066] Specifically, the cooperation between the second auxiliary blade 33 and the second main blade 43 allows materials at higher positions within the mixing shell 1 to be further refined when passing through this area, ensuring that the final particle size of the material meets the required standard and further increasing the effective range of the mixing and crushing blades.

[0067] like Figures 1 to 5 As shown, in this embodiment, there are multiple pulverizing auxiliary blades 3, and the multiple pulverizing auxiliary blades 3 are arranged circumferentially along the inner wall of the mixing shell 1. Under the rotational cutting action of the pulverizing main blade 4, the material is first initially pulverized by the pulverizing main blade 4, and then further ground and refined by the participation of multiple pulverizing auxiliary blades 3. The arrangement of multiple auxiliary blades ensures that the material can pass through the action of the blades multiple times during the processing, thereby gradually refining the material to the required particle size.

[0068] Because multiple secondary blades are spaced apart circumferentially along the inner wall of the housing, the material will come into uniform contact with each secondary blade throughout the rotation process. This ensures that the material is subjected to grinding and cutting action from multiple secondary blades with each rotation, thus ensuring uniformity in the cutting process and the refinement effect of the material.

[0069] Furthermore, multiple auxiliary blades share the material processing task, avoiding excessive burden on a single blade during the processing, thereby effectively reducing blade wear and improving overall work efficiency.

[0070] Furthermore, the synergistic effect of multiple secondary blades and the main crushing blade 4 ensures that the material is gradually ground and refined when it enters the working area of ​​each secondary blade. The design and position of each secondary blade determine its role in the material processing process, thereby effectively controlling the fineness of the material and avoiding over-cutting or under-processing of the material at any stage.

[0071] Furthermore, the synergistic effect of multiple secondary blades and the main crushing blade 4 ensures that the material is cut and ground more evenly in each secondary blade area. The participation of multiple blades reduces the risk of material accumulation or blockage, ensuring a smooth and efficient processing process.

[0072] Furthermore, the multiple auxiliary blades 3 enable the main crushing blade 4 to cut and grind the material multiple times during rotation. The multiple auxiliary blades mean that the material can be processed by multiple auxiliary blades during each rotation, reducing the processing time each time and thus accelerating the material processing. Each auxiliary blade can play a role when the material passes by, thereby reducing the workload of each auxiliary blade and increasing processing efficiency. The material completes multiple stages of cutting and refining in a shorter time, avoiding excessively long waiting time and processing cycles.

[0073] Furthermore, through multiple chopping and grinding processes, the material can be refined into sufficiently small particles, which facilitates the efficiency of subsequent processing techniques (such as drying, fermentation, composting, or biodegradation).

[0074] like Figures 1 to 5 As shown, the rotary cutter shaft 2 of this embodiment includes a cutter shaft body 21 and a feeding assembly 22 disposed on the cutter shaft body 21. The feeding assembly 22 can transport the material in the mixing shell 1 to the top of the cutter shaft body 21 and then throw it out.

[0075] Specifically, the cutter shaft body 21 is the core part of the rotating cutter shaft 2, which is responsible for supporting the cutter and driving the rotation. The feeding assembly 22 can push the material in the mixing shell 1 to the top of the cutter shaft body 21. The material is lifted by the feeding assembly and is quickly thrown out after passing the top of the rotating cutter shaft. This process not only helps the material to be transported vertically, but also increases the contact opportunity between the material and the rotating cutter, thereby improving the material processing efficiency.

[0076] Specifically, the feeding assembly 22 applies force to the material, gradually lifting the material in the mixing shell 1 to the top of the cutter shaft body 21. At this time, the feeding assembly 22 helps the material overcome gravity through rotation or pushing, and delivers it to the working area of ​​the cutter shaft.

[0077] When the material reaches the top of the cutter shaft body 21, the rotational power of the feeding assembly 22 throws the material out, allowing it to enter the next stage of cutting, grinding, or refining. Through this conveying and throwing process, the material does not remain in a certain area within the mixing shell 1 and continue to be shredded by the cutter. It maintains high fluidity and uniformity during the processing, ensuring that the material has sufficient fluidity within the mixing shell 1. Through continuous conveying and throwing, the material can undergo multiple cutting and grinding stages by the cutter, ensuring the refining effect and helping to improve the efficiency of the entire processing system.

[0078] Specifically, the feeding assembly 22 can effectively transport the material in the mixing shell 1 to the top of the cutter shaft, avoiding the accumulation or retention of material in the mixing shell 1. This process can ensure that the material enters the working area of ​​the cutter shaft evenly, improving the material handling efficiency of the entire system.

[0079] Furthermore, the design of the feeding assembly 22 typically provides a continuous material lifting force through structures such as spirals, blades, or scrapers. This prevents materials from becoming stuck at the bottom of the mixing shell 1 due to factors such as gravity or friction during processing, thereby further improving production efficiency.

[0080] Furthermore, the feeding assembly 22 can transport the material from the bottom to the top of the cutter shaft body 21 and quickly eject it. Under the action of the rotating cutter shaft, the material can be more evenly distributed in the working area of ​​the cutter. The participation of multiple material layers allows each material particle to be processed more evenly during cutting and grinding, avoiding over-cutting or refining of the material in certain areas and ensuring the consistency of particle size.

[0081] Furthermore, the feeding component ensures continuous material transport, preventing materials from stagnating within the equipment and reducing unnecessary idling or downtime. It effectively avoids transport disruptions caused by excessive material accumulation. Through continuous transport, materials are processed in a timely manner, ensuring continuous flow throughout the entire process, preventing blockages, and improving overall production speed and efficiency.

[0082] like Figures 1 to 5 As shown, the feeding assembly 22 in this embodiment includes a spiral channel on the outer wall of the cutter shaft body 21. With this design, when the cutter shaft body 21 rotates, it drives the spiral channel to rotate at the same time, so as to drive the material at the bottom of the mixing shell 1 to gradually rise along the spiral channel and be thrown out from the top of the spiral channel, so as to realize the scattering of the material in the mixing shell 1, so that the mixing and crushing cutter can carry out multiple mixing, crushing and grinding processes on the material, so that the material can be crushed evenly.

[0083] Specifically, the spiral channel is located on the outer wall of the cutter shaft body 21. As the cutter shaft body 21 rotates, the spiral channel will also rotate synchronously. The design of the spiral channel allows the material to be pushed and guided to rise along the spiral path when it is driven by the rotating cutter shaft body.

[0084] When the cutter shaft body 21 starts to rotate, the spiral channel pushes the material at the bottom of the mixing shell 1 upward through its spiral-shaped channel structure. The material is driven to rise gradually by the spiral channel and is eventually thrown out through the top of the spiral channel.

[0085] After the material is thrown out from the top of the spiral channel, it will re-enter the working area of ​​the blades. Due to the continuous throwing of the material in the mixing shell 1, the mixing and crushing blades can contact and process the material multiple times, thereby cutting, mixing and grinding the material multiple times, making the particle size of the material more uniform. This process makes the crushed particle size of the material more uniform and improves the overall crushing effect.

[0086] Through the design of the spiral channel, the material not only undergoes the cutting and grinding action of the blades during the continuous lifting and throwing process, but also comes into full contact with other materials in the mixing shell, which further promotes the uniform processing and refinement of the material.

[0087] The spiral channel design not only helps to convey materials upwards, but also prevents materials from accumulating or stagnating in the mixing shell 1. The flowability of materials is optimized throughout the process, enabling the system to work continuously and efficiently.

[0088] Because the spiral design of the spiral channel can efficiently transport materials from the bottom to the top of the mixing shell 1, the conveying task can be completed quickly during the material handling process, shortening the waiting time of materials and improving the overall production speed.

[0089] Preferably, the spiral channel can be made of spiral blades. This design allows the spiral channel to not only convey the material but also cut it, further improving the cutting effect of the blade.

[0090] Preferably, in this embodiment, multiple main crushing blades 4 are connected to a spiral channel and are arranged sequentially from bottom to top along the axial direction of the rotating blade shaft 2. Each stirring arm 41 is located on the back of the spiral channel. This design optimizes the structure of the crushing and stirring blades, making them more compact, and avoids the stirring arms 41 from affecting the conveying effect of the spiral channel. Furthermore, the stirring arms 41 can act as reinforcing ribs of the spiral channel, making the structure of the rotating blade shaft 2 more stable.

[0091] Furthermore, this design allows multiple main crushing blades 4 to perform stepped upward or downward crushing and grinding actions on the same auxiliary crushing blade 3 during each rotation of the cutting tool system. The multiple main crushing blades 4 are gradually raised along the spiral channel and work in synergy with the auxiliary crushing blade 3. When the rotating cutter shaft 2 starts to rotate, the main crushing blades 4 contact the material in sequence at different height positions. During each rotation, the material is gradually crushed and ground layer by layer under the action of multiple main crushing blades.

[0092] The cooperation between each main crushing blade 4 and the secondary crushing blade 3 allows the material to undergo cutting and grinding of different intensities within the same rotation cycle. The main crushing blade 4 cuts and grinds upward or downward in a stepped manner in the spiral channel, ensuring that the material is gradually refined and eventually achieves a uniform particle size.

[0093] As multiple crushing blades 4 rise or fall sequentially along the spiral channel axially, the material undergoes multiple different levels of crushing action during rotation. Each crushing blade 4 can efficiently cut and grind materials of different heights, ensuring not only the uniform refinement of the material but also improving the cutting accuracy.

[0094] Specifically, multiple crushing blades 4 cut and grind along different stepped positions in each rotation, allowing the material to undergo multiple processing cycles in each rotation. This design greatly improves the speed and efficiency of material refinement, ensuring that each particle receives uniform and fine processing. Through stepped cutting and grinding actions, the material can be fully processed within each rotation cycle of the blade system, greatly shortening processing time and improving production efficiency.

[0095] Furthermore, with each rotation, the stepped chopping and grinding design avoids over-crushing or insufficient refining of materials, ensuring the uniformity of material particle size and improving the quality of the final product. Under the action of the blades at different step positions, the material is gradually cut and ground, avoiding local over-refining or uneven particle size distribution caused by the material staying in the process for too long. The synergistic effect of multiple main crushing blades 4 and auxiliary blades 3 ensures uniform material processing.

[0096] Preferably, in other embodiments, the conveying assembly 22 may also adopt other structural forms, such as: a blade-type feeding assembly, in which multiple blades are installed on the rotating cutter shaft 2, and the material is pushed along the surface of the blades by rotation. The blades may be designed to be curved, which can apply a continuous pushing force to the material, so that the material is pushed from the bottom or middle to the top of the mixing shell 1.

[0097] The scraper-type feeding assembly pushes the material through a scraper mounted on the cutter shaft body 21. The scraper is usually mounted on the rotating shaft. When the cutter shaft body 21 rotates, the scraper scrapes the material up and pushes it upward. A suitable design can be selected according to actual needs.

[0098] Preferably, each of the auxiliary blade connecting sections 31 is inclined on the inner wall of the mixing shell 1, that is, each of the pulverizing auxiliary blades 3 is inclined on the inner wall of the mixing shell 1. Through this inclined arrangement, the pulverizing auxiliary blades 3 can cooperate more effectively with the pulverizing main blade 4 to contact and cut the material.

[0099] Specifically, the inclined setting of the secondary crushing blade 3 allows the material to contact the blades of the main crushing blade 4 and the secondary crushing blade 3 at a more suitable angle during rotation, thereby achieving more efficient cutting and grinding. This inclined angle increases the contact area between the material and the blades, optimizing the crushing effect of the material.

[0100] Specifically, the inclined setting of the crushing secondary blade 3 allows it to cut deeper into the material during rotation, thereby achieving more efficient cutting and grinding. This setting ensures that each layer of the material can be fully cut, avoiding the situation where some materials are not fully crushed during the processing.

[0101] Due to the tilt angle of each secondary blade 3, the material is cut and ground at different angles when passing through each secondary blade, further refining the material particles. Through the action of multiple tilting secondary blades, the material is processed multiple times and evenly, ensuring the uniformity and refinement effect of material crushing.

[0102] The angle design of the inclined secondary blade helps to adapt to the flow direction of the material in the mixing shell 1, so that the material can come into contact with the blade more naturally, improving the flowability of the material and avoiding material stagnation or jamming.

[0103] The tilted secondary blade not only helps the material enter the cutting area better, but also allows the material to be ground and crushed more evenly as it passes through the blade, avoiding excessive concentration in one place.

[0104] The inclined design of the 3rd pulverizing blade makes each cut more effective, allowing the material to pass through the blade area more quickly and be cut and ground multiple times, thereby improving the overall pulverizing efficiency. The material is fully cut under the action of the blade, thus reducing processing time and improving production efficiency.

[0105] The tilted secondary blade design allows for more efficient contact with the material and cuts at a more reasonable angle, enabling rapid refinement of the material's particle size while also preventing material stagnation during processing.

[0106] Preferably, in other embodiments, the pulverizing auxiliary blade 3 is arranged vertically or nearly vertically inside the stirring housing 1, and a suitable design can be selected according to actual needs.

[0107] Preferably, the bottom of the first main blade 42 located at the lowest point is close to or abuts against the bottom inner wall of the mixing shell 1, and the side wall of the first main blade 42 is close to or abuts against the inner side wall of the mixing shell 1 near the bottom. With this design, the first main blade 42 can agitate the material at the bottom of the mixing shell 1, ensuring the movement of the material at the bottom of the mixing shell 1, and ensuring that the material at the bottom of the mixing shell 1 can be transported to the top of the cutter shaft body 21 by the feeding assembly 22 for throwing.

[0108] Preferably, the bottom of the stirring arm 41 of the first main blade 42 is further provided with an auxiliary chopping section 411. The auxiliary chopping section 411 is provided with a plurality of spaced first auxiliary blades 412. The first auxiliary blades 412 can chop the material at the bottom of the stirring shell 1, further reducing the retention or jamming of material at the bottom of the stirring shell 1.

[0109] Preferably, the bottom of the mixing shell 1 is provided with a plurality of spaced second auxiliary blades 413. During each rotation of the blade system, each first auxiliary blade 412 can pass between two second auxiliary blades 413. Through the blades of the first auxiliary blade 412 and the blades between the first auxiliary blade 412 and the second auxiliary blade 413, the material is chopped. Furthermore, when the first auxiliary blade 412 passes between two second auxiliary blades 413, and when the second auxiliary blade 413 passes through the gap between the first auxiliary blade 412 and the auxiliary chopping section 411, the material is ground, further improving the chopping and grinding effect of the blades on the material at the bottom of the mixing shell 1.

[0110] Preferably, the first secondary blade 32, the second secondary blade 33, the first main blade 42, and the second main blade 43 are all blades with a certain thickness, and each blade has a certain cutting edge on its side wall.

[0111] Specifically, the thickness of the blade body provides greater structural strength and wear resistance, enabling it to maintain stable cutting performance under high loads and long-term operation. This makes the blade less prone to deformation or damage during material handling, resulting in high durability.

[0112] Specifically, the moderately thick blade body can not only withstand a large material handling load, but also maintain the sharpness of the blade after multiple uses, avoiding a decrease in processing efficiency due to blade wear or breakage. This design improves the impact resistance of the blade, enabling it to operate stably for a long time.

[0113] Specifically, each blade has a certain cutting edge on its side wall. This design ensures that the material can be cut efficiently when passing through the blade. The blades are reasonably distributed and can form the best contact angle with the material, thereby achieving more precise cutting and grinding.

[0114] A blade with a defined cutting edge provides a sharper cutting effect, making it easier to cut and pulverize materials as they pass through. The blade design ensures a sufficiently large contact area between the material and the blade, thereby improving cutting efficiency and quality.

[0115] The contact between each blade and the material allows the material to be cut and ground multiple times as it passes through multiple blades. The blades with sufficient thickness ensure that the material is fully crushed and refined at each stage, and that the blades are not easily damaged during grinding, thus ensuring their normal operation.

[0116] The thickness of the blade design increases the impact resistance of the blade body. When processing harder materials, the blade is less likely to break or deform. Furthermore, for harder materials, the thickness of the blade allows for the compression and crushing of the material between the side walls and the cutting edge of the main blade and the secondary blade, ensuring the cutting and crushing effect of the material. This design reduces the failure or damage of the blade due to frequent impacts, thereby reducing the maintenance frequency and replacement cost.

[0117] Due to the reasonable thickness design and blade distribution of the cutting tools, the tools can maintain their sharpness for a longer period of time, thereby reducing the need for frequent tool replacements and lowering equipment maintenance costs. Furthermore, the thickness and impact-resistant design of the tool body make the tools more robust, greatly reducing the probability of equipment failure under high load. Stable equipment operation can reduce downtime and production losses, thereby lowering the overall maintenance costs of the equipment.

[0118] Furthermore, with this design, the cutting edge of the knife does not need to be too sharp, ensuring user safety.

[0119] In other embodiments, the first secondary blade 32, the second secondary blade 33, the first main blade 42, and the second main blade 43 are all blade structures; or, the first secondary blade 32 and the second secondary blade 33 are blade bodies with a certain thickness, and the first main blade 42 and the second main blade 43 are blade structures; or, the first main blade 42 and the second main blade 43 are blade bodies with a certain thickness, and the first secondary blade 32 and the second secondary blade 33 are blade structures; a suitable design can be selected according to actual needs.

[0120] Preferably, the pulverizing blade 3 is integrally formed with the stirring shell 1 or is detachably connected, and a suitable design can be selected according to actual needs.

[0121] like Figure 6 As shown, in some other embodiments, multiple first main blades 42 are stacked and spaced above and below each first main blade 42 to correspond to multiple first auxiliary blades 32. The second auxiliary blade 33 may or may not be provided; a suitable design can be selected according to actual needs.

[0122] like Figures 1 to 5As shown in this embodiment, a food waste processing device includes a mixing shell 1 and a mixing and pulverizing blade as described in any of the above embodiments. Preferably, the food waste processing device further includes a drive mechanism, which is connected to a rotating blade shaft 2 to drive the main pulverizing blade to rotate. The blade can mix and initially chop the material, breaking down larger food waste into smaller pieces. The relative movement between the main pulverizing blade and the first auxiliary blade, through the contact of their blades, achieves the chopping action of the material. Furthermore, there is a grinding gap between the main pulverizing blade and the first auxiliary blade. The grinding gap allows the material to be further squeezed and rubbed between the main pulverizing blade and the first auxiliary blade after chopping, thereby achieving fine grinding of the material. This grinding process can not only further refine the size of the material, but also improve the processing efficiency of the material. It has significant advantages, especially for materials with high moisture content or that are difficult to cut (such as nut shells, bones, etc.), which can greatly reduce the size of the material and improve the efficiency of subsequent processing (such as composting or biodegradation).
