Description

Technical Field

[0001] The invention relates to the technical field of kitchen waste treatment, and in particular to a stirring and crushing tool with good grinding effect and kitchen waste treatment equipment using the tool. Background Art

[0002] With the continuous acceleration of urbanization, the amount of kitchen waste generated by the catering industry and household kitchens is also increasing. How to efficiently deal with kitchen waste has become an urgent problem to be solved. Traditional kitchen waste treatment methods, such as landfill and incineration, have faced many problems such as environmental pollution and waste of resources. Therefore, the development and promotion of 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 today's technological development.

[0003] Existing food waste treatment equipment mainly uses mechanical stirring knives to chop food waste for subsequent treatment. Usually, the stirring knives equipped with food waste treatment equipment mostly use a rotary cutting method to physically crush the food waste to achieve a certain chopping effect. The design principle and structure of this knife enable it to cut large pieces of food waste into small pieces to a certain extent, which is convenient for subsequent further treatment and resource utilization. However, these existing stirring knives only have chopping and stirring functions and lack sufficient grinding capacity.

[0004] Specifically, although the existing mixing knives can divide large pieces of food waste into multiple small pieces during the chopping process, since the main working mode of the knives is cutting and mixing, the chopped materials often remain large in size. This large material size not only affects the subsequent processing efficiency, but also increases the difficulty of equipment cleaning and maintenance. In some application scenarios that require finer crushing and grinding, the existing mixing knife design obviously cannot meet the requirements, resulting in limitations in the processing effect. For example, for kitchen waste materials that contain more water or are relatively hard (such as bones, nut shells, etc.), existing mixing knives may not be able to effectively further refine them into sufficiently small particles, thereby affecting the efficiency of subsequent processing processes (such as drying, fermentation, composting or biodegradation, etc.).

DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, a stirring and crushing tool with good grinding effect in this embodiment comprises a rotating blade shaft 2 rotatably connected to a stirring shell 1 and a crushing auxiliary blade 3 arranged on the inner wall of the stirring shell 1, the crushing auxiliary blade 3 comprises an auxiliary blade connecting section 31 arranged on the inner wall of the stirring shell 1 and a first auxiliary blade 32 arranged on one side of the auxiliary blade connecting section 31, the number of the first auxiliary blade 32 is at least one, at least one crushing main blade 4 is arranged on the rotating blade shaft 2, the first auxiliary blade 32 and the crushing main blade 4 are arranged in upper and lower layers, and a grinding gap 5 is provided between the two, and the side walls of the first auxiliary blade 32 and the crushing main blade 4 are both provided with blades, when the rotating blade shaft 2 rotates and drives the crushing main blade 4 to rotate to the first auxiliary blade 32, the crushing main blade 4 and the first auxiliary blade 32 can perform a shredding action on the material through the blades, and the crushing main blade 4 and the first auxiliary blade 32 can perform a grinding action on the material through the grinding gap 5, Specifically, when the rotating blade shaft 2 drives the main crushing blade 4 to rotate, it can mix and preliminarily shred the material, break up and divide the larger kitchen waste into small pieces, and the relative movement between the main crushing blade 4 and the first auxiliary blade 32 realizes the shredding action of the material through the contact of the blades of the two. In particular, when the rotating blade shaft 2 rotates and drives the main crushing blade 4 to rotate to the position of the first auxiliary blade 32, the contact of the blades of the two can effectively cut the material into smaller pieces, avoiding the limitation of traditional knives that only perform single shredding. In addition, there is a certain gap between the main crushing knife 4 and the first auxiliary knife 32 to form a grinding gap 5. The grinding gap allows the material to be further squeezed and rubbed between the main crushing knife 4 and the first auxiliary knife 32 after being chopped, 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, 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 processes (such as composting or biodegradation).

[0022] This design realizes the integration of three functions through a tool system, making the equipment's workflow more compact and efficient. Traditional equipment can usually only realize the shredding function and cannot have the grinding function at the same time. This equipment design can not only shred the material, but also refine the material, so that it can cope with rough processing and adapt to occasions requiring high-precision crushing.

[0023] Due to the combination of shredding and grinding functions, the shredded materials can not only be further refined after entering the grinding gap, but also accelerate the decomposition process of the materials, reducing the problems of material accumulation or handling difficulties that may occur in subsequent processes, especially when handling complex materials (such as bones, fruit shells, etc.), it can improve the processing efficiency, and the shredding and grinding of materials between the knives can effectively adapt to kitchen waste with different characteristics. Whether it is soft fruit and vegetable waste, or hard bones or dry hard materials, they can be effectively processed by this tool system, making the equipment highly adaptable in various application scenarios.

[0024] like Figures 1 to 5 As shown, the crushing main knife 4 of this embodiment includes a stirring arm 41 and a first main knife 42. The two ends of the stirring arm 41 are respectively connected to the first main knife 42 and the rotating knife shaft 2. Specifically, the stirring arm 41 functions to stir the material through a rotational motion. When the rotating knife shaft 2 drives the stirring arm 41 to rotate, the stirring arm can stir the material evenly to prevent material accumulation or blockage, thereby ensuring that the material can be evenly distributed during the entire processing process.

[0025] Specifically, the first main knife 42 is connected to the stirring arm 41, and can chop the material while stirring. When the stirring arm 41 drives the rotating knife shaft 2 to rotate, the first main knife 42 will cut the material and can cut large pieces of material into smaller pieces. This shredding function can effectively reduce the particle size of the material and provide an ideal material size for subsequent grinding.

[0026] After the material is chopped by the first main knife 42, the blade of the first auxiliary knife 32 can cooperate with the blade of the first main knife 42 to further chop the material and further refine the size of the material.

[0027] Moreover, while the material is being chopped, it can pass through the grinding gap 5 and be further squeezed and rubbed between the blade of the first auxiliary blade 32 and the blade of the first main blade 42, thereby producing a grinding effect. This fine grinding effect can further reduce the particle size of the material and improve the processing efficiency.

[0028] 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 process; and the first main knife 42 can cut the material into small pieces, making the material more suitable for subsequent grinding and other processing processes, and can provide a strong chopping effect for hard materials (such as bones, nut shells, etc.); and through the design of the first auxiliary knife 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.

[0029] This design can achieve multiple processing of materials through the synergistic effect of the stirring arm 41, the first main knife 42 and the first auxiliary knife 32, by combining the stirring, chopping and grinding functions in one tool system, and provide higher processing efficiency when processing materials. Furthermore, through the dual effects of chopping and grinding, this tool can finely adjust the particle size of the material so that the material can reach the ideal particle size level at different processing stages. This design enables the equipment to maintain a high processing accuracy when facing different types of materials.

[0030] like Figures 1 to 5 As shown, in this embodiment, there are multiple first auxiliary knives 32, and the multiple first auxiliary knives 32 are arranged at intervals from top to bottom along the auxiliary knife connecting section 31. There are multiple first main knives 42, and each first main knife 42 is located between two first auxiliary knives 32 adjacent to it above and below.

[0031] Specifically, multiple first auxiliary knives 32 are arranged at intervals along the auxiliary knife connecting section 31, and each first main knife 42 is located between two adjacent first auxiliary knives 32. When the rotating knife shaft 2 drives these first main knives 42 to rotate, each main knife will cooperate with the auxiliary knives 32 adjacent to it above and below, and each pair of adjacent first main knives 42 and first auxiliary knives 32 can produce shredding and grinding effects. In this way, after the material is processed by the combination of multiple main knives and auxiliary knives, it can be cut into finer particles and ground at the same time. This arrangement can ensure that the material is evenly processed during the shredding process, thereby avoiding the situation where some material is not fully processed.

[0032] Due to the cooperation between each first main cutter and the two auxiliary cutters, the material will undergo multiple stages of cutting and grinding when passing through these cutters. Each stage will have an effect on the material, gradually refining the particle size of the material. After the material passes through the grinding gap between each main cutter and auxiliary cutter, it is further squeezed and rubbed by the blade to refine its particles. This not only ensures the thoroughness of material processing, but also optimizes the uniformity of material particles and improves processing efficiency.

[0033] The design of multiple first auxiliary knives 32 allows the material to be chopped and ground by multiple blades during the processing, and the chopping and grinding effects are evenly distributed. Compared with the traditional single auxiliary knife design, this design can more efficiently refine the material and ensure that each part of the material can be fully processed.

[0034] Specifically, multiple first main knives 42 and first auxiliary knives 32 work side by side, which increases the chopping and grinding effects of the knives while also improving the material processing capacity per unit time. The alternating operation of multiple main knives and auxiliary knives enables more materials to be processed each time they rotate, thereby improving the overall processing efficiency.

[0035] Furthermore, multiple auxiliary knives are set at intervals to help effectively break up the material during the processing process and prevent the material from piling up or getting clogged between the knives due to incomplete chopping or grinding. Each auxiliary knife can gradually refine and decompose the material, allowing the material to pass through the knife more smoothly.

[0036] The combination of multiple auxiliary knives and main knives ensures that the material can be evenly processed during the shredding and grinding process. Each auxiliary knife acts on the material at a different position, which can avoid excessive processing of the material at certain positions while insufficient action is taken on other positions. Through the combination of multiple auxiliary knives and main knives, the material can be evenly distributed, ensuring that every part of the material is shredded and ground.

[0037] In addition, multiple main cutters and auxiliary cutters can share the workload and prevent a single cutter from being subjected to excessive cutting or grinding pressure. This design not only extends the service life of the cutter, but also reduces the maintenance frequency of the equipment. The load on each cutter is relatively light, which helps to maintain stable operation of the equipment.

[0038] like Figures 1 to 5 As shown, each of the first main knives 42 of this embodiment can have a grinding gap 5 with the corresponding two first auxiliary knives 32, that is, each of the first main knives 42 has a grinding gap 5 with the first auxiliary knives 32 located on the upper and lower sides thereof. Specifically, the grinding gap 5 between the first main knife 42 and the upper and lower adjacent first auxiliary knives 32 is designed as a key processing area when the material passes through. Driven by the rotating knife shaft 2, the first main knife 42 and the blades of the upper and lower auxiliary knives 32 form relative motion, generating cutting force and grinding force.

[0039] When the material passes through the grinding gap between the first main knife 42 and the two first auxiliary knives 32, it is squeezed and rubbed by the first main knife 42 and the upper and lower first auxiliary knives 32, and the particle size is gradually refined. The material is effectively constrained to ensure the uniformity of the particle size, and improve the grinding range and grinding rate.

[0040] Furthermore, the distance between the first main knife 42 and the two first auxiliary knives 32 is relatively close, so that the first main knife 42 and the two first auxiliary knives 32 can achieve shredding, further improving the shredding effect of the knife.

[0041] like Figures 1 to 5 As shown, the plurality of first main knives 42 of this embodiment are arranged at intervals along the circumference of the rotating knife shaft 2, and the plurality of first main knives 42 are arranged to rise in sequence from bottom to top along the axial direction of the rotating knife shaft 2.

[0042] Preferably, multiple first main cutters 42 are evenly distributed along the circumference of the rotating cutter shaft 2 to ensure that the material is evenly cut during the rotation of the cutter shaft. This circumferential arrangement enables each main cutter to contact the material during rotation, thereby sharing the work of cutting and grinding the material and avoiding excessive wear or excessive burden on local cutters.

[0043] Furthermore, each first main knife 42 can exert cutting force on the material during the rotation process, and multiple main knives work simultaneously, thereby improving the overall shredding efficiency and ensuring the uniformity of the material cutting effect. The material can be fully processed when passing through each main knife.

[0044] And a plurality of first main cutters 42 are arranged in a rising manner from bottom to top on the rotating cutter shaft 2. As the rotating cutter shaft rotates, the main cutters 42 at the top gradually contact the material, while the main cutters 42 at the bottom are responsible for the initial material shredding. The axially rising arrangement enables the material to be gradually subjected to different degrees of cutting and grinding when passing through the main cutters at different heights, so that the stirring and crushing cutters can stir and crush the materials at different heights in the stirring shell 1, ensuring that the working range of the stirring and crushing cutters can cover the materials in the entire stirring shell 1.

[0045] Specifically, a plurality of first main knives 42 are evenly spaced along the circumference of the rotating knife shaft 2, ensuring that the material can be cut and ground multiple times in each rotation of the knife system, so that the material can be further evenly chopped, thereby improving the overall cutting efficiency.

[0046] Furthermore, the plurality of first main knives 42 can perform material cutting multiple times, which can greatly shorten the processing time, so that each rotation can effectively process more materials, reducing waiting time and processing cycle.

[0047] like Figures 1 to 5 As shown, each of the crushing main cutter 4 in this embodiment also includes a second main cutter 43, and the second main cutter 43 is located above the corresponding first main cutter 42, and a grinding space 44 is provided between the two. When the crushing main cutter 4 rotates to the first auxiliary cutter 32, the corresponding first auxiliary cutter 32 can relatively move into the grinding space 44, and the top of the first auxiliary cutter 32 can form a grinding gap 5 with the bottom of the second main cutter 43, and the bottom of the first auxiliary cutter 32 and the top of the first main cutter 42 form a grinding gap 5.

[0048] Specifically, each crushing main knife 4 is composed of two main knives. The first main knife 42 and the second main knife 43 form a mutually coordinated action area through the design of the grinding space 44. When the crushing main knife 4 rotates, the material can be cut by passing through the first main knife 42 and the second main knife 43, thereby realizing double cutting. When the crushing main knife 4 rotates to the position of the first auxiliary knife 32, the first auxiliary knife 32 can move relatively to the grinding space 44 and move relatively to the grinding gap between the first main knife 42 and the second main knife 43. In this way, the cooperation between the first auxiliary knife 32 and the first main knife and the second main knife can achieve multi-stage grinding, and in the process of the first auxiliary knife 32 moving relatively to the grinding space 44, the first main knife 42 and the second main knife 43 can cooperate with the corresponding first auxiliary knife 32 to achieve multiple cutting.

[0049] Specifically, when the material passes through multiple tool areas, each tool can perform different degrees of shredding or grinding on the material. The multi-stage grinding and cutting design makes material processing more efficient, especially when processing harder materials. The effect of each stage can ensure that the material particle size is gradually refined, thereby improving the overall work efficiency and allowing the material to be shredded evenly.

[0050] 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 knife 32, or adjusting the distance between the first main knife 42 and the second main knife 43 on the stirring arm 41, a suitable design can be selected according to actual needs.

[0051] like Figures 1 to 5 As shown, the crushing auxiliary knife 3 of this embodiment further includes a second auxiliary knife 33 , the bottom of the second auxiliary knife 33 can form a grinding gap 5 with the top of the second main knife 43 of the crushing main knife 4 located at the highest point.

[0052] Specifically, the second auxiliary knife 33 is located in the design of the crushing auxiliary knife 3, usually at the upper part of the system, close to or directly on the top of the second main knife 43, which enables the second auxiliary knife 33 to form a precise grinding gap 5 with the second main knife 43.

[0053] After the material is initially cut by the first main knife 42 and the second main knife 43, a grinding gap 5 is formed between the bottom of the second auxiliary knife 33 and the top of the second main knife 43 to further finely grind the material. In this process, the second auxiliary knife 33 provides additional grinding force through the gap between the second auxiliary knife 33 and the second main knife 43 to ensure further refinement of the material.

[0054] Specifically, the cooperation between the second auxiliary blade 33 and the second main blade 43 enables the materials at a higher position in the mixing shell 1 to be further refined when passing through this area, ensuring that the particle size of the final materials reaches the required standard and further increasing the range of action of the mixing and crushing tools.

[0055] like Figures 1 to 5As shown, the number of the crushing auxiliary knives 3 in this embodiment is multiple, and the multiple crushing auxiliary knives 3 are arranged at intervals along the circumferential direction of the inner wall of the mixing shell 1. Under the rotating cutting action of the crushing main knife 4, the material is first preliminarily chopped by the crushing main knife 4, and then further ground and refined through the participation of multiple crushing auxiliary knives 3. The distribution of multiple auxiliary knives ensures that the material can pass through the action of the knives multiple times during the processing process, thereby gradually refining the material to the required particle size.

[0056] Since multiple auxiliary knives are arranged at circumferential intervals along the inner wall of the shell, the material will evenly contact each auxiliary knife during the entire rotation process, so that the material can be ground and cut by multiple auxiliary knives during each rotation, ensuring the uniformity of the cutting process and the refinement effect of the material.

[0057] Furthermore, multiple auxiliary cutters share the material processing task, avoiding excessive burden on a single cutter during the processing process, thereby effectively reducing the wear rate of the cutter and improving overall work efficiency.

[0058] Furthermore, the synergistic effect of multiple auxiliary knives and the crushing main knife 4 can ensure that the material can be gradually ground and refined when entering the action area of ​​each auxiliary knife. The design and position of each auxiliary knife determines its role in the material processing process, thereby effectively controlling the degree of material refinement and avoiding excessive cutting or insufficient processing of the material at any stage.

[0059] Furthermore, with the synergistic effect of multiple auxiliary knives and the crushing main knife 4, the material will be cut and ground more evenly in each auxiliary knife area. The participation of multiple knives reduces the risk of material accumulation or blockage, ensuring a smooth and efficient processing process.

[0060] Furthermore, the provision of multiple auxiliary knives 3 enables the crushing main knife 4 to cut and grind the material multiple times when it rotates. The provision of multiple auxiliary knives means that the material can be processed by multiple auxiliary knives in each rotation, reducing the time of each processing, thereby speeding up the material processing process. Each auxiliary knife can play a role when the material passes through, thereby reducing the workload of each auxiliary knife and increasing the processing efficiency. The material completes multiple stages of cutting and refinement in a shorter time, avoiding excessive waiting time and processing cycle.

[0061] Furthermore, through multiple chopping and grinding, the material can be refined into particles small enough to facilitate the efficiency of subsequent processing processes (such as drying, fermentation, composting or biodegradation).

[0062] like Figures 1 to 5As shown, the rotating blade shaft 2 of this embodiment includes a blade shaft body 21 and a feeding assembly 22 arranged on the blade shaft body 21, and the feeding assembly 22 can transport the material in the mixing shell 1 to the top of the blade shaft body 21 and then throw it out.

[0063] Specifically, the blade shaft body 21 is the core part of the rotating blade shaft 2, which is responsible for supporting the blade and driving the rotation. The feeding component 22 can push the material in the mixing shell 1 to the top of the blade shaft body 21. The material is lifted by the feeding component and is quickly thrown out after passing the top of the rotating blade shaft. This process not only helps the material to be transported vertically, but also enhances the contact opportunity between the material and the rotating blade, thereby improving the material processing efficiency.

[0064] Specifically, the feeding component 22 exerts force on the material, gradually lifting the material in the mixing shell 1 to the top of the blade shaft body 21. At this time, the feeding component 22 helps the material overcome gravity through rotation or pushing action and delivers it to the working area of ​​the blade shaft.

[0065] 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 processing. Through this conveying and throwing process, the material will not stay in a certain area in the mixing shell 1 to continue the cutter's chopping process. During the processing, it maintains a high fluidity and uniformity, so that the material can have sufficient fluidity in the mixing shell 1. Through continuous conveying and throwing, the material can go through multiple cutting and grinding stages of the cutter, ensuring the refinement effect, which helps to improve the efficiency of the entire processing system.

[0066] 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 the material in the mixing shell 1. This process can ensure that the material evenly enters the working area of ​​the cutter shaft, thereby improving the material processing efficiency of the entire system.

[0067] Furthermore, the design of the feeding assembly 22 usually provides continuous material lifting force through structures such as spirals, blades or scrapers, which can prevent the material from being retained at the bottom of the mixing shell 1 due to factors such as gravity or friction during the processing process, further improving production efficiency.

[0068] Furthermore, the feeding assembly 22 can transport the material from the bottom to the top of the cutter shaft body 21 and quickly throw it out. Under the action of the rotating cutter shaft, the material can be more evenly distributed in the tool working area. The participation of multiple material layers enables each material particle to be processed more evenly during cutting and grinding, avoiding excessive cutting or refinement of the material in certain areas and ensuring the consistency of particle size.

[0069] Furthermore, the function of the feeding component ensures the continuous conveying of materials, avoids stagnation of materials in the equipment, thereby reducing unnecessary idling or stop time, and effectively avoids the problem of poor transportation caused by excessive accumulation of materials. Through continuous conveying, materials are processed in time, ensuring the continuous flow of materials throughout the entire processing process, preventing blockages, and improving the overall speed and efficiency of production.

[0070] like Figures 1 to 5 As shown, the feeding assembly 22 of this embodiment includes a spiral channel arranged on the outer wall of the blade shaft body 21. Such a design is adopted so that when the blade shaft body 21 rotates, the spiral channel is driven to turn and 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 to realize the scattering of the material in the mixing shell 1, so that the mixing and crushing tool can perform multiple mixing, crushing and grinding processes on the material, so that the material can be crushed evenly.

[0071] Specifically, the spiral channel is disposed 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 enables the material to be pushed and guided to rise along the spiral path when driven by the rotating cutter shaft body.

[0072] When the blade shaft body 21 starts to rotate, the spiral channel continuously pushes the material at the bottom of the mixing shell 1 upward through its spiral channel structure. The material is driven by the spiral channel to gradually rise and is finally thrown out through the top of the spiral channel.

[0073] After the material is thrown out from the top of the spiral channel, it will enter the working area of ​​the tool again. As the material is continuously thrown in the mixing shell 1, the mixing and crushing tool can contact and process the material multiple times, thereby cutting, mixing and grinding the material multiple times to make 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.

[0074] Through the design of the spiral channel, the material not only experiences the cutting and grinding action of the cutter during the process of being continuously lifted and scattered, but also can fully contact with other materials in the mixing shell, further promoting the uniform processing and refinement of the material.

[0075] The design of the spiral channel not only helps to transport the material upward, but also prevents the material from accumulating or staying in the mixing shell 1. The fluidity of the material in the whole process is optimized, so that the system can work continuously and efficiently.

[0076] Since the spiral design of the spiral channel can efficiently transport the material from the bottom to the top of the mixing shell 1, the conveying task can be completed quickly during the material processing process, shortening the waiting time of the material and improving the overall production speed.

[0077] Preferably, the spiral channel may adopt a spiral blade. With such a design, the spiral channel has the function of conveying the material body and also has the function of cutting the material body, further improving the cutting effect of the tool on the material body.

[0078] Preferably, in this embodiment, a plurality of the main crushing knives 4 are connected to the spiral channel, and are arranged to rise in sequence from bottom to top along the axial direction of the rotating knife shaft 2 along the spiral channel, and each of the stirring arms 41 is arranged on the back of the spiral channel. Such a design can optimize the structure of the stirring and crushing tool, making its structure more compact, and avoid the stirring arm 41 affecting the conveying effect of the spiral channel. Furthermore, the stirring arm 41 can act as a reinforcement rib of the spiral channel, making the structure of the rotating knife shaft 2 more stable.

[0079] Moreover, such a design is adopted, so that in each rotation of the tool system, multiple main crushing knives 4 on the same auxiliary crushing knife 3 can realize a stepped upward or downward crushing and grinding action, and the multiple main crushing knives 4 are gradually raised along the spiral channel and form a synergistic effect with the auxiliary crushing knife 3. When the rotating knife shaft 2 starts to rotate, the main crushing knife 4 contacts the material in turn at different height positions. In each rotation, the material is crushed and ground layer by layer and step by step under the action of the multiple main crushing knives.

[0080] The cooperation between each main crushing knife 4 and the auxiliary crushing knife 3 enables the material to undergo cutting and grinding of different intensities within the same rotation cycle. The main crushing knife 4 cuts and grinds upward or downward in a step-by-step manner in the spiral channel, ensuring that the material is gradually refined and finally reaches a uniform particle size.

[0081] Since the multiple crushing main knives 4 are raised or lowered axially along the spiral channel in turn, the material will undergo multiple different levels of shredding actions during the rotation process. The crushing main knives 4 at each layer can efficiently cut and grind materials at different heights, which not only ensures the uniform refinement of the material, but also improves the cutting accuracy.

[0082] Specifically, multiple crushing main knives 4 cut and grind along different step positions in each rotation, so that the material can undergo multiple processing during each rotation. This design greatly improves the speed and efficiency of material refinement, ensuring that each particle is processed evenly and carefully. Through the stepped cutting and grinding actions, the material can be fully processed within each rotation cycle of the tool system, greatly shortening the processing time and improving production efficiency.

[0083] Furthermore, during each rotation, the stepped shredding and grinding design avoids over-crushing or insufficient refinement of the material, ensures the uniformity of the material particle size, and improves the quality of the final product. The material is gradually cut and ground under the action of the cutters at different step positions, avoiding local over-refinement or uneven particle size distribution caused by the material staying for too long during the processing. The synergistic effect of multiple crushing main knives 4 and auxiliary knives 3 ensures uniform processing of the material.

[0084] Preferably, in other embodiments, the conveying component 22 can also adopt other structural forms, such as: a blade-type feeding component, in which multiple blades are installed on the rotating knife shaft 2, and the material is pushed along the surface of the blade through rotation. The blade design can be curved, which can exert a continuous driving force on the material, so that the material is pushed from the bottom or middle of the mixing shell 1 to the top.

[0085] The scraper-type feeding assembly pushes the material by means of a scraper installed on the cutter shaft body 21. The scraper is usually installed on a rotating shaft. When the cutter shaft body 21 rotates, the scraper scrapes up the material and pushes it upwards. A suitable design can be selected according to actual needs.

[0086] Preferably, each of the auxiliary knife connecting sections 31 is inclined on the inner wall of the mixing shell 1, that is, each of the crushing auxiliary knives 3 is inclined on the inner wall of the mixing shell 1. Through this inclined setting, the crushing auxiliary knife 3 can more effectively cooperate with the crushing main knife 4 to contact and cut the material.

[0087] Specifically, the inclined setting of the crushing auxiliary knife 3 enables the material to contact the blades of the crushing main knife 4 and the crushing auxiliary knife 3 at a more suitable angle during the rotation process, thereby achieving more efficient cutting and grinding. This inclination angle increases the contact area between the material and the tool and optimizes the crushing effect of the material.

[0088] Specifically, the inclined setting of the crushing auxiliary knife 3 enables 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 process.

[0089] Due to the inclination angle setting of each auxiliary knife 3, the material will be cut and ground at different angles when passing through each auxiliary knife, further refining the material particles. Through the action of multiple inclined auxiliary knives, the material is processed multiple times and evenly, ensuring the uniformity and refinement of material crushing.

[0090] The angle design of the inclined auxiliary knife helps to adapt to the flow direction of the material in the mixing shell 1, so that the material can contact the knife more naturally, improve the fluidity of the material, and avoid material retention or jamming.

[0091] The inclined auxiliary knife not only helps the material to enter the cutting area better, but also enables the material to be ground and crushed more evenly in the process of passing through the knife, avoiding the phenomenon of excessive concentration in a certain position.

[0092] The inclined design of the crushing auxiliary knife 3 makes each cut more effective. The material can pass through the knife area more quickly and be cut and ground multiple times, thereby improving the overall crushing efficiency. The material is fully cut under the action of the knife, thereby reducing the processing time and improving production efficiency.

[0093] The design of the inclined auxiliary blade can contact the material more efficiently and cut at a more reasonable angle, so that the particle size of the material can be quickly refined, while also avoiding stagnation of the material during the processing process.

[0094] Preferably, in some other embodiments, the secondary crushing blade 3 is vertically or nearly vertically arranged in the mixing shell 1, and a suitable design can be selected according to actual needs.

[0095] Preferably, the bottom of the first main knife 42 located at the lowest point is close to or against the bottom inner wall of the mixing shell 1, and the side wall of the first main knife 42 is close to or against the inner wall of the mixing shell 1 near the bottom. With such a design, the first main knife 42 can stir the material at the bottom of the mixing shell 1, ensure the movement of the material at the bottom of the mixing shell 1, and ensure that the material at the bottom of the mixing shell 1 can be transported to the top of the knife shaft body 21 through the feeding assembly 22 for throwing.

[0096] Preferably, an auxiliary chopping portion 411 is also provided at the bottom of the stirring arm 41 of the above-mentioned first main knife 42, and a plurality of first auxiliary knife bodies 412 are arranged at intervals in the auxiliary chopping portion 411. The first auxiliary knife bodies 412 can chop the material at the bottom of the stirring shell 1, thereby further reducing the retention or jamming of the material at the bottom of the stirring shell 1.

[0097] Preferably, a plurality of second auxiliary blades 413 are provided at an interval at the bottom of the mixing shell 1. During each rotation of the tool system, each of the first auxiliary blades 412 can pass between two second auxiliary blades 413, and achieve a chopping effect on the material through the blade of the first auxiliary blade 412 and the blade between the first auxiliary blade 412 and the second auxiliary blade 413. Moreover, when the first auxiliary blade 412 passes between the 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 part 411, a grinding effect can be achieved on the material, thereby further improving the chopping and grinding effect of the tool on the material at the bottom of the mixing shell 1.

[0098] Preferably, the first auxiliary knife 32, the second auxiliary knife 33, the first main knife 42 and the second main knife 43 are all knife bodies with a certain thickness, and the side walls of the knife bodies are all provided with certain cutting edges.

[0099] Specifically, the thickness of the cutter body provides greater structural strength and wear resistance, and is able to maintain stable cutting performance during high load and long-term operation, which makes the cutter less likely to deform or be damaged during material handling and has higher durability.

[0100] Specifically, a blade body with moderate thickness can not only withstand a large material processing load, but also maintain the sharpness of the blade after repeated use, avoiding the decrease in processing efficiency due to blade wear or breakage. This design improves the impact resistance of the tool and enables the tool to operate stably for a long time.

[0101] Specifically, each blade has a certain blade on the side wall. This design ensures that the material can be cut efficiently when passing through the tool. The blade is reasonably distributed and can form an optimal contact angle with the material, thereby achieving more precise cutting and grinding.

[0102] The blade body with a certain blade can provide a sharper cutting effect, making it easier to cut and crush the material when passing through the knife. The design of the blade ensures that the contact area between the material and the knife is large enough, thereby improving the efficiency and quality of cutting.

[0103] The contact between each cutter body and the material enables the material to be cut and ground multiple times when passing through multiple cutters. The cutter body with sufficient thickness ensures that the material can be fully crushed and refined at each stage, ensuring that the cutter body is not easily damaged during grinding and ensuring its normal operation.

[0104] The thickness of the tool design increases the impact resistance of the tool body. When processing harder materials, the tool is not easy to break or deform. In addition, for harder materials, the thickness of the tool can allow the side walls and blades of the main and auxiliary tools to squeeze and crush the materials, ensuring the cutting and crushing effect of the materials. This design reduces the failure or damage of the tool due to frequent impact, thereby reducing the maintenance frequency and replacement cost.

[0105] Due to the reasonable thickness design and blade distribution of the tool, the tool can maintain its sharpness for a long time, thereby reducing the need for frequent tool replacement and reducing the maintenance cost of the equipment. The thickness and impact-resistant design of the tool body make the tool more sturdy, and the probability of equipment failure during high-load operation is greatly reduced. Stable operation of the equipment can reduce downtime and production losses, thereby reducing the overall maintenance cost of the equipment.

[0106] Moreover, by adopting such a design, the cutting edge of the knife can be set not to be too sharp, thus ensuring the safety of the user.

[0107] In other embodiments, the first auxiliary knife 32, the second auxiliary knife 33, the first main knife 42 and the second main knife 43 are all blade structures; or, the first auxiliary knife 32 and the second auxiliary knife 33 are knife bodies with a certain thickness, and the first main knife 42 and the second main knife 43 are blade structures; or, the first main knife 42 and the second main knife 43 are knife bodies with a certain thickness, and the first auxiliary knife 32 and the second auxiliary knife 33 are blade structures; the appropriate design can be selected according to actual needs.

[0108] Preferably, the crushing auxiliary blade 3 is integrally formed with the stirring shell 1 or is detachably connected thereto, and a suitable design can be selected according to actual needs.

[0109] like Figure 6 As shown, in other embodiments, a plurality of first main knives 42 are stacked and spaced above and below each first main knife 42 to correspond to a plurality of first auxiliary knives 32, and the second auxiliary knife 33 may or may not be provided; a suitable design may be selected according to actual needs.

[0110] like Figures 1 to 5 As shown, a kitchen waste processing device of the present embodiment comprises a stirring shell 1 and a stirring and crushing tool as described in any one of the above items. Preferably, the kitchen waste processing device also comprises a driving mechanism, which is transmission-connected to the rotating cutter shaft 2 to drive the crushing main cutter to rotate. The cutter can stir and preliminarily chop the material, break up and divide the larger kitchen waste into small pieces, but the relative movement between the crushing main cutter and the first auxiliary cutter realizes the chopping action of the material through the contact of the blades of the two, and there is a grinding gap between the crushing main cutter and the first auxiliary cutter. The grinding gap makes the material further squeezed and rubbed between the crushing main cutter and the first auxiliary cutter after being chopped, so as to realize the fine grinding of the material. The grinding process can not only further refine the size of the material, but also improve the processing efficiency of the material, especially for materials with high moisture content or difficult to cut (such as nut shells, bones, etc.), it has obvious advantages, can greatly reduce the size of the material, and improve the efficiency of subsequent processing processes (such as composting or biodegradation).

[0111] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
