[0004] Specifically, although the existing stirring cutters can divide large pieces of food waste into multiple small pieces during the cutting process, due to the main action mode of the cutters being cutting and stirring, the cut materials often still maintain a large size, such a 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 more fine crushing and grinding, the existing stirring cutter design obviously cannot meet the requirements, resulting in the limitation of processing effect, for example, for kitchen materials containing more moisture or being relatively hard (such as bones, nut shells, etc.), the existing stirring cutters may not be able to effectively further refine them into small enough particles, thereby affecting the efficiency of subsequent processing processes (such as drying, fermentation, composting or biodegradation, etc.).

[0005] The utility model is proposed to solve the problems in the prior art. TECHNICAL SOLUTION

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

[0019] This utility model relates to a novel mixing and pulverizing blade and a kitchen waste treatment device using the blade, relating to the technical field of kitchen waste treatment. The mixing and pulverizing blade includes a rotating blade shaft and pulverizing auxiliary blades. The rotating blade shaft is equipped with a main pulverizing blade. Specifically, the rotating blade shaft is driven to rotate within the mixing housing by a power source such as a motor, causing the main pulverizing blades on the shaft to rotate as well. This allows multiple main blades to effectively pulverize the kitchen waste within the mixing housing. Through a design where multiple auxiliary blades and main blades are staggered, the blades of the main and auxiliary blades cooperate with each other, and the contact between the main and auxiliary blades results in the material being pulverized into smaller particles. When the main blade rotates to the pulverizing auxiliary blade, the pulverized material can enter the grinding gap and be further ground through friction between the blades of the main and auxiliary blades.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 5As shown, the new stirring and crushing cutter of the embodiment comprises a rotating knife shaft 2 rotatably connected in the stirring shell 1 and a crushing auxiliary cutter 3 arranged on the inner wall of the stirring shell 1. The crushing auxiliary cutter 3 comprises an auxiliary cutter connecting section 31 arranged on the inner wall of the stirring shell 1 and a plurality of first auxiliary cutters 32 arranged on one side of the auxiliary cutter connecting section 31. The plurality of first auxiliary cutters 32 are arranged in intervals from top to bottom along the auxiliary cutter connecting section 31. The rotating knife shaft 2 is provided with a crushing main cutter 4. The crushing main cutter 4 comprises a connecting section 41 and a plurality of first main cutters 42 arranged on the side wall of the connecting section 41. The plurality of first main cutters 42 are arranged in intervals from top to bottom along the connecting section 41, and the plurality of first main cutters 42 and the first auxiliary cutters 32 are arranged in an interlaced manner. The first main cutters 42 and the first auxiliary cutters 32 have a grinding gap 5 therebetween. The side walls of the first auxiliary cutters 32 and the first main cutters 42 are provided with cutting edges. When the rotating knife shaft 2 rotates and drives the first main cutters 42 to rotate to the crushing auxiliary cutter 3, the first main cutters 42 and the first auxiliary cutters 32 can cut the materials through the cutting edges, and the first main cutters 42 and the first auxiliary cutters 32 can grind the materials through the grinding gap 5.

[0028] Specifically, the rotating knife shaft 2 is driven to rotate in the stirring shell 1 by a power source such as a motor, and drives the crushing main cutter 4 on the knife shaft to rotate, so that the plurality of first main cutters 42 can effectively cut the kitchen waste in the stirring shell 1. Moreover, through the interlaced arrangement of the plurality of first auxiliary cutters 32 and the first main cutters 42, the cutting edges of the main cutters 42 and the auxiliary cutters 32 cooperate with each other, the contact between the main cutters and the auxiliary cutters causes the materials to be cut into smaller particles, forming further cutting action. When the first main cutters 42 rotate to the crushing auxiliary cutter 3, the cut materials can enter the grinding gap 5 and rub against the blade of the first main cutters 42 and the blade of the crushing auxiliary cutter 3, thereby further grinding the materials. This grinding action can further refine the materials, achieving a more thorough treatment effect.

[0029] During the entire working process, the materials are cut by the main cutters and the auxiliary cutters, and are refined into smaller particles through the grinding gap between the cutters. This grinding process not only further refines the size of the materials, but also improves the processing efficiency of the materials. In particular, it has obvious advantages for materials with high moisture content or difficult to cut (such as nut shells, bones, etc.), which can greatly reduce the size of the materials and improve the efficiency of subsequent processing processes (such as composting or biodegradation).

[0030] By adding the grinding gap 5 in the cutter design, the grinding function of the cutter can be effectively improved, so that even hard food residues (such as bones, fruit pits, nut shells, etc.) can be effectively ground into small particles, improving the processing effect of the materials.

[0031] And through the staggered design of the main cutter and the secondary cutter, and the action of the grinding gap, the material can not only be quickly cut when passing through the cutter, but also be further refined after cutting, thereby improving the processing speed and efficiency, which enables the equipment to more efficiently process a large amount of kitchen waste and reduce the processing time.

[0032] The design realizes the integration of the three functions through a cutter system, making the working process of the equipment more compact and efficient. Traditional equipment can only achieve the chopping function and cannot simultaneously have the grinding function. The present equipment design can not only chop but also refine the material, making it suitable for both rough processing and occasions requiring high-precision crushing.

[0033] Due to the combination of chopping and grinding functions, the chopped material can be further refined and the decomposition process of the material can be accelerated after entering the grinding gap, reducing the problem of material accumulation or processing difficulty that may occur in subsequent processes, especially when processing complex materials such as bones and fruit shells. The processing efficiency can be improved, and the combination of chopping and grinding between the cutters can effectively adapt to different characteristics of kitchen waste. Whether it is soft fruit and vegetable waste or hard bones or dry material, it can be effectively processed by the cutter system, making the equipment have high adaptability in various application scenarios.

[0034] As shown in Figures 1 to 5 The number of the crushing secondary cutter 3 is multiple, and the multiple crushing secondary cutters 3 are circumferentially spaced along the inner wall of the stirring shell 1, ensuring that the material can be uniformly cut during the entire waste processing process. Each secondary cutter contacts the material at the inner wall of the stirring shell, and under the driving of the rotating cutter shaft 2, these secondary cutters cooperate with the rotating primary cutter to form a continuous cutting and grinding effect. The distribution of multiple secondary cutters can effectively cover the entire processing area and enhance the chopping effect.

[0035] Moreover, the crushing secondary cutter 3 is circumferentially spaced, so that the material can continuously contact the secondary cutter during rotation and be uniformly distributed. This design can ensure that the material is not concentrated in a certain position and is not excessively cut or worn, but is uniformly affected by the cutter, thereby improving the overall processing efficiency.

[0036] The multiple arrangement of the crushing secondary cutter 3 not only chops the material when it passes between the crushing primary cutter 4 and the crushing secondary cutter 3, but also refines the material through the dual action of cutting and grinding. The crushing secondary cutter 3 assists the crushing primary cutter 4 in further refining while chopping, and the distribution of the crushing secondary cutter 3 ensures that the material inside the stirring shell can be effectively processed.

[0037] Further, the plurality of secondary crushing knives 3 are evenly distributed along the inner wall, which can ensure uniform cutting and processing of the materials during the entire processing process, avoid concentrated load, and reduce knife wear. This design greatly improves the processing efficiency, especially when processing a large amount of materials, it can ensure efficient processing of materials.

[0038] Further, the interval arrangement of the secondary crushing knives 3 can promote the flow and distribution of the materials, and avoid the accumulation of materials in a certain position, which can cause incomplete processing.

[0039] Further, after the plurality of secondary crushing knives 3 are evenly distributed, they can more effectively cut hard food residues such as bones, fruit pits, and nut shells. The synergistic effect of the plurality of secondary crushing knives 3 and the primary crushing knives 4 can make the hard materials more fully crushed.

[0040] Further, by distributing the plurality of secondary crushing knives 3 on the inner wall of the shell, the load of each secondary crushing knife 3 is reduced, which helps to reduce vibration, noise, and wear during equipment operation. The combined effect of the plurality of secondary crushing knives 3 can also make the equipment run more smoothly, improve the service life and operational reliability of the equipment.

[0041] Further, since the plurality of secondary crushing knives 3 share the processing load, the knife wear rate is relatively slow, which reduces the frequency of equipment maintenance and replacement costs. Through optimized design, the service life of the knife is extended, and the complexity and cost of daily maintenance are reduced.

[0042] As shown in Figures 1 to 5 The secondary knife connecting section 31 of the present embodiment is inclined on the inner wall of the stirring shell 1, so that the secondary knife connecting section 31 is inclined at a certain angle relative to the horizontal position of the stirring shell. Due to the inclination of the secondary knife connecting section 31, the plurality of first secondary knives 32 are arranged in a stepped manner thereon, that is, the installation angle of each first secondary knife 32 is gradually different, forming a stepped layout. This stepped arrangement optimizes the angle and cutting method of the first secondary knives 32 in contact with the materials, thereby enhancing the cutting and decomposition effect of the materials.

[0043] During the rotation of the rotating knife shaft 2 driving the primary crushing knives 4, the first primary knives 42 can cooperate with the first secondary knives 32 distributed along the inclined surface of the secondary knife connecting section 31. Due to the different cutting angles between the first secondary knives 32, the contact between the materials and the first secondary knives 32 and the first primary knives 42 becomes more flexible and diversified, thereby achieving the effect of multi-point cutting. This design can prevent the accumulation of materials in a certain position, ensure uniform distribution of materials in the entire knife system, and obtain more complete cutting and grinding.

[0044] And, with the stepped arrangement of the first secondary knives 32, the material can be gradually refined when passing through the coordinated cutting between the plurality of first secondary knives 32 and the first primary knife 42, increasing the cutting and grinding opportunities of each first secondary knife 32. This layer-by-layer progressive cutting method enables the material to obtain a more refined crushing effect in a short time.

[0045] And, due to the stepped layout of the first secondary knives 32, the material will not stagnate at a certain position when passing through the cutter, but can flow better along the cutter surface, thereby forming a stepped grinding effect between the first secondary knives 32 and the first primary knife 42. This design helps to avoid material accumulation and ensures uniform distribution of the material in the cutter area, ensuring that the material is cut and ground multiple times during processing, significantly improving the processing efficiency of the material.

[0046] Due to the inclined arrangement of the secondary knife connecting section 31, the cutting range of the crushing secondary knife 3 in the stirring shell 1 is improved, and the cutting efficiency is improved.

[0047] As shown in Figures 1 to 5 The connecting portion 41 of the present embodiment is inclinedly arranged on the rotating cutter shaft 2, so that the first primary knife 42 is arranged in an inclined stepped manner on the connecting portion 41.

[0048] Specifically, the connecting portion 41 is arranged on the rotating cutter shaft 2 by an inclined design. This inclined arrangement changes the working angle and cutting direction of the crushing primary knife 4, enabling different cutting angles and cutting forces during rotation. This arrangement changes the way the material contacts the first primary knife 42, thereby improving the cutting effect and processing efficiency.

[0049] Specifically, based on the inclination of the connecting portion 41, the plurality of first primary knives 42 are arranged in a stepped manner, i.e., the installation angle of each primary knife is slightly different, forming a layer-by-layer progressive layout. This stepped layout enables each first primary knife 42 to exert different cutting forces on the material when rotating, thereby optimizing the overall effect of cutting and grinding.

[0050] Under the drive of the rotating cutter shaft 2, the plurality of first primary knives 42 contact the material at a stepped angle, and rely on their different installation angles and cutting sequences to form an efficient cutting synergy with the material. The inclined arrangement enables each primary knife to not only work independently, but also to gradually cut or refine the material through progressive cutting, avoiding the problem of material blockage or insufficient processing.

[0051] Further, the plurality of first primary knives 42 can simultaneously and sequentially cut the material within the same rotation period, ensuring that the material is fully processed and the cutting efficiency is greatly improved.

[0052] Furthermore, due to the stepped arrangement of the first main blade 42, the material is guided along the cutting area between multiple first main blades 42 and first auxiliary blades 32 during rotation, avoiding material accumulation in a certain position. The material is gradually dispersed and evenly guided to different blade areas for further processing. This optimized design effectively avoids uneven cutting or blockage caused by material accumulation.

[0053] The inclined arrangement of the first main blades 42 and the stepped cutting allow each first main blade 42 on the rotating cutter shaft to cut materials at different cutting angles, making it particularly adept at handling hard materials (such as bones, nut shells, and fruit pits). Through a progressive cutting process, the materials are gradually refined, ensuring that even hard materials can be thoroughly crushed.

[0054] Through an inclined and stepped arrangement design, the multiple primary blades 42 can share the cutting burden of the material during rotation, preventing any single primary blade 42 from bearing excessive pressure for a long time. In this way, the wear of the blades is evenly distributed, reducing blade wear or damage caused by concentrated loads and extending the service life of the blades.

[0055] Furthermore, with the stepped arrangement of the first main blades 42, the material can be gradually refined when it is cut by the coordinated cutting of multiple first secondary blades 32 and the first main blades 42, increasing the cutting and grinding opportunities of each first main blade 42. This progressive cutting method allows the material to achieve a finer crushing effect in a short time.

[0056] Furthermore, due to the stepped layout of the first main blade 42, the material will not stagnate at a certain position when passing through the blade, but can flow better along the blade surface. This results in a stepped grinding effect between the first secondary blade 32 and the first main blade 42. This design helps to avoid material accumulation and ensures that the material is evenly distributed in the blade area. It also ensures that the material is cut and ground multiple times during the processing, which significantly improves the material processing efficiency.

[0057] like Figures 1 to 5 As shown, the connecting part 41 of this embodiment is provided with a through hole 411, through which the material can pass through the connecting part 41. The main purpose of providing the through hole 411 on the connecting part 41 is to allow the material to flow more freely during the processing. The through hole 411 provides an additional path for the material to pass through the connecting part 41, thereby avoiding the accumulation or retention of the material during the processing.

[0058] The design of the through hole 411 prevents the material from getting stuck at the connection part 41 when passing through the blade, and reduces the resistance of the material to the crushing blade 4, avoiding unnecessary stoppages or energy waste. The through hole improves the smoothness of the system and reduces the burden of material accumulation on the operation of the equipment.

[0059] like Figures 1 to 5 As shown, the rotary cutter shaft 2 of this embodiment is also provided with a bottom wall stirring section 43 that can stir the material at the bottom of the stirring shell 1. The bottom of the bottom wall stirring section 43 is close to or abuts against the bottom inner wall of the stirring shell 1.

[0060] In terms of design, the bottom of the bottom wall stirring section 43 is close to or abuts against the bottom inner wall of the stirring shell 1. This ensures that the stirring section can effectively contact the material at the bottom. During rotation, the bottom wall stirring section will push the material to flow along the bottom area of ​​the stirring shell 1. The bottom wall stirring section 43 can continuously stir up the material at the bottom and mix it with the material at the top, preventing the material from stagnating or accumulating at the bottom due to gravity. This ensures that the material in the entire container can be fully cut and ground, ensuring the uniformity of stirring and cutting.

[0061] Specifically, the bottom wall stirring section 43 works together with the main and auxiliary blades on the rotating cutter shaft 2 to create a strong flow and cutting effect within the stirring shell. The bottom wall stirring section 43 can not only break up the material deposits at the bottom, but also promote the continuous flow of materials within the stirring shell, enhancing the contact between the blades and the materials and improving the cutting and grinding effect.

[0062] like Figures 1 to 5 As shown, the bottom of the connecting part 41 in this embodiment is connected to the bottom wall stirring section 43, so that the bottom wall stirring section 43 can be driven by the rotating cutter shaft 2 during rotation. After the bottom wall stirring section 43 and the bottom of the connecting part 41 are connected, the two become a whole working component, ensuring that the stirring section 43 can be in close contact with the bottom of the stirring shell 1. In this way, the material can be processed more evenly during stirring and cutting.

[0063] As the rotating cutter shaft 2 rotates, the bottom wall stirring section 43 stirs at the bottom of the stirring shell 1. This stirring section design makes it difficult for materials to settle at the bottom of the shell, preventing materials from accumulating for a long time and being unable to enter the subsequent cutting or grinding process. Since the bottom wall stirring section 43 is connected to the bottom of the connecting part 41, the stability and efficiency of the stirring section are improved throughout the entire rotation process.

[0064] The connection between the connecting part and the bottom wall mixing section improves the stability of the connecting part, making it more stable during rotation and less prone to shaking or imbalance. This allows the connecting part and the bottom wall mixing section to more effectively mix the materials inside the mixing shell 1, reducing vibration during equipment operation and improving overall operational stability.

[0065] This design also makes the tool structure more compact.

[0066] like Figures 1 to 5 As shown, the connecting part 41 in this embodiment includes a stirring arm 412 and a connecting arm 413. The connecting arm 413 is connected to the stirring arm 412 and the bottom wall stirring section 43 respectively. The stirring arm 412 and the bottom wall stirring section 43 are staggered so that the connecting arm 413 is inclined. The first main blade 42 is provided on the side wall of the connecting arm 413.

[0067] Specifically, the connecting part 41 consists of a stirring arm 412 and a connecting arm 413. The two work together to enhance the stirring and flowability of the material. The stirring arm 412 is responsible for stirring and pushing the material, while the connecting arm 413 connects the stirring arm 412 to the bottom wall stirring section 43. The advantage of this structure is that the connecting arm 413, by being inclined, can better contact the material and push the material upward and outward, thereby ensuring the uniform processing of the material.

[0068] The staggered design of the mixing arm 412 and the bottom wall mixing section 43 allows the material to be more mixed and processed at the bottom. The purpose of the staggered design is to avoid dead angles or excessive overlap between the mixing arm and the bottom wall mixing section, ensuring smoother flow of material in the bottom area. At the same time, this staggered design helps guide the material to different areas of the entire equipment, improving the efficiency of cutting and mixing.

[0069] The inclined design of the connecting arm 413 ensures that the angle between the stirring arm 412 and the bottom wall stirring section 43 matches the material flow direction. Through this inclined arrangement, the connecting arm 413 can effectively push the material, thereby improving the contact efficiency between the stirring section and the bottom material and reducing material accumulation. In addition, the inclined setting helps to increase the contact area between the stirring section and the material, thereby improving the processing efficiency.

[0070] Specifically, the first main blade 42 is set on the side wall of the connecting arm 413. This design ensures that the first blade can effectively cut the material during the material flow. The position of the side wall of the connecting arm 413 optimizes the angle and force of the first main blade 42 in contact with the material, thereby achieving a more efficient cutting effect. The design of the first main blade 42 enables the material to be quickly cut or ground when it passes through, thereby improving the processing speed and effect.

[0071] Specifically, the tilt angle of the connecting arm 413, the staggered arrangement of the stirring arm 412 and the bottom wall stirring section 43, and the optimized position of the first main blade 42 form a highly efficient material handling system. The material is fully stirred, cut and ground in the equipment. The whole process has high fluidity and uniformity, avoiding material retention, accumulation or insufficient processing. The synergistic effect between the parts can ensure that the material is processed quickly and evenly, thereby improving the overall work efficiency.

[0072] Preferably, the through hole 411 is formed by the bottom wall stirring section 43, the connecting arm 413, the stirring arm 412, and the rotating cutter shaft 2.

[0073] like Figures 1 to 5 As shown, in this embodiment, both the first main blade 42 and the first secondary blade 32 are blades with a certain thickness, and both have a certain cutting edge on the side wall of the blade.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Furthermore, with this design, the cutting edge of the knife does not need to be too sharp, ensuring user safety.

[0082] In other embodiments, both the first secondary blade 32 and the first main blade 42 are blade structures; or, the first secondary blade 32 is a blade body with a certain thickness and the first main blade 42 is a blade structure; or, the first main blade 42 is a blade body with a certain thickness and the first secondary blade 32 is a blade structure; a suitable design can be selected according to actual needs.

[0083] 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.

[0084] 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.

[0085] Preferably, the number of the main crushing blades 4 is at least one, and a suitable design can be selected according to requirements.

[0086] 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 first main 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 first main blade and the first auxiliary blade. The grinding gap allows the material to be further squeezed and rubbed between the first main 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).
