Description

Technical Field

[0001] The invention relates to the technical field of kitchen waste treatment, and in particular to a novel stirring and crushing cutter and kitchen waste treatment equipment using the cutter. 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.).

[0005] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0010] In the novel stirring and crushing tool as described above, the connecting portion is arranged obliquely on the rotating blade shaft so that the first main blades are arranged in an inclined stepped manner on the connecting portion.

[0012] In the novel stirring and crushing tool as described above, the rotating cutter shaft is also provided with a bottom wall stirring section capable of stirring the material at the bottom of the stirring shell, and the bottom of the bottom wall stirring section is close to or against the inner wall of the bottom of the stirring shell.

[0013] In the novel stirring and crushing tool as described above, the bottom of the connecting portion is connected to the stirring section of the bottom wall.

[0016] A kitchen waste processing device comprises a stirring shell and a novel stirring and crushing cutter as described in any one of the above items.

[0017] The beneficial effects of the present invention are: The present invention discloses a novel stirring and crushing tool and a kitchen waste treatment device using the tool, which relate to the technical field of kitchen waste treatment. The stirring and crushing tool comprises a rotating blade shaft and at least one crushing auxiliary blade, wherein at least one crushing main blade is arranged on the rotating blade shaft.

DETAILED DESCRIPTION

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

[0021] like Figures 1 to 5As shown, a new type of stirring and crushing tool of this embodiment includes a rotating blade shaft 2 rotatably connected to the stirring shell 1 and a crushing auxiliary blade 3 arranged on the inner wall of the stirring shell 1, the number of the crushing auxiliary blade 3 is at least one, the crushing auxiliary blade 3 includes an auxiliary blade connecting section 31 arranged on the inner wall of the stirring shell 1 and a plurality of first auxiliary blades 32 arranged on one side of the auxiliary blade connecting section 31, the plurality of first auxiliary blades 32 are arranged at intervals from top to bottom along the auxiliary blade connecting section 31, at least one crushing main blade 4 is arranged on the rotating blade shaft 2, the crushing main blade 4 includes a connecting portion 41 and a plurality of first main blades 42 arranged on the side wall of the connecting portion 41, The plurality of first main knives 42 are arranged at intervals from top to bottom along the connecting portion 41, and the plurality of first main knives 42 and the first auxiliary knives 32 are staggered, and a grinding gap 5 is provided between adjacent first main knives 42 and first auxiliary knives 32. The side walls of the first auxiliary knives 32 and the first main knives 42 are provided with blades. When the rotating knife shaft 2 rotates and drives the first main knife 42 to rotate to the crushing auxiliary knife 3, the first main knife 42 and the first auxiliary knife 32 can perform shredding action on the material through the blades, and the first main knife 42 and the first auxiliary knife 32 can perform grinding action on the material through the grinding gap 5.

[0022] Specifically, the rotating blade shaft 2 is driven to rotate in the mixing shell 1 by a power source such as a motor, driving the crushing main blade 4 on the blade shaft to rotate, so that the multiple first main blades 42 can effectively cut the kitchen waste in the mixing shell 1, and through the design of staggered arrangement of multiple first auxiliary blades 32 and the first main blade 42, the blades of the main blade 42 and the auxiliary blade 32 cooperate with each other, and the contact between the main blade and the auxiliary blade causes the material to be cut into smaller particles, forming a further cutting effect. When the first main blade 42 rotates to the crushing auxiliary blade 3, the chopped material can enter the grinding gap 5, and rub through the blade body of the first main blade 42 and the blade body of the crushing auxiliary blade 3, so as to further grind the material. This grinding action can further refine the material and achieve a more thorough processing effect.

[0023] During the entire working process, after the material is cut by the main knife and the auxiliary knife, it is refined into smaller particles through the grinding gap between the knives. 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.). It has obvious advantages and can greatly reduce the size of the material and improve the efficiency of subsequent processing processes (such as composting or biodegradation).

[0024] By adding a grinding gap 5 to the tool design, the grinding function of the tool can be effectively improved, so that even hard food residues (such as bones, fruit cores, nut shells, etc.) can be effectively ground into fine particles, improving the material processing effect.

[0025] And through the staggered design of the main knife and the auxiliary knife, as well as the role of the grinding gap, the material can not only be cut quickly when passing through the knife, but also be further refined after cutting, thereby improving the processing speed and efficiency. This enables the equipment to process large amounts of kitchen waste more efficiently and reduce processing time.

[0026] 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.

[0027] 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.

[0028] like Figures 1 to 5 As shown, the number of crushing auxiliary knives 3 in this embodiment is multiple, and the multiple crushing auxiliary knives 3 are arranged at intervals along the circumference of the inner wall of the mixing shell 1, ensuring that the material can be cut evenly during the entire garbage processing process. Each auxiliary knife will contact the material at the inner wall of the mixing shell. Under the drive of the rotating knife shaft 2, these auxiliary knives cooperate with the rotating main knife to form a continuous cutting and grinding action. The distribution of multiple auxiliary knives can effectively cover the entire processing area and enhance the shredding effect.

[0029] In addition, the crushing auxiliary knives 3 are arranged at intervals along the circumference, so that the material can continuously contact the auxiliary knives and be evenly distributed during the rotation process. This design ensures that the material will not be concentrated in a certain position and be over-cut or worn, but will be evenly affected by the knife, thereby improving the overall processing efficiency.

[0030] The multiple arrangements of the crushing auxiliary knives 3 can not only shred the materials when they pass between the crushing main knife 4 and the crushing auxiliary knife 3, but also refine the materials through the dual effects of cutting and grinding. The crushing auxiliary knife 3 can assist the crushing main knife 4 in further refining while shredding. The distribution of the crushing auxiliary knife 3 can ensure that the materials inside the mixing shell can be effectively processed.

[0031] Furthermore, multiple crushing auxiliary knives 3 are evenly distributed along the circumference of the inner wall, so that the material can be evenly cut and processed during the entire processing process, avoiding concentrated loads and reducing tool wear. This design greatly improves the processing efficiency, especially when processing large amounts of material, and can ensure efficient processing of the material.

[0032] Furthermore, the spaced arrangement of the auxiliary crushing knives 3 can promote the flow and distribution of materials, and avoid the situation where materials are accumulated at a certain location and thus lead to incomplete processing.

[0033] Furthermore, after multiple crushing auxiliary knives 3 are evenly distributed, they can more effectively cut hard food residues, such as bones, fruit cores, nut shells and other hard objects. The synergistic effect of these crushing auxiliary knives 3 and the crushing main knife 4 enables the hard objects to be crushed more fully.

[0034] Furthermore, by distributing multiple crushing auxiliary knives 3 on the entire inner wall of the shell, the load on a single crushing auxiliary knife 3 is reduced, which helps to reduce vibration, noise and wear during equipment operation. The combined effect of multiple crushing auxiliary knives 3 can also make the equipment run more smoothly and improve the service life and operational reliability of the equipment.

[0035] Furthermore, since the plurality of crushing auxiliary knives 3 share the processing load, the wear rate of the knives is relatively slow, reducing the frequent maintenance and replacement costs of the equipment. Through the optimized design, the service life of the knives is extended, and the complexity and cost of daily maintenance are reduced.

[0036] like Figures 1 to 5 As shown, the auxiliary knife connecting section 31 of the present embodiment is tilted on the inner wall of the mixing shell 1, so that the auxiliary knife connecting section 31 is tilted at a certain angle relative to the horizontal position of the mixing shell. Due to the inclination of the auxiliary knife connecting section 31, multiple first auxiliary knives 32 are arranged in a stepped manner thereon, that is, the installation angle of each first auxiliary knife 32 is gradually different, forming a stepped layout. This stepped arrangement optimizes the contact angle and cutting method of the first auxiliary knife 32 with the material, thereby enhancing the cutting and decomposition effect of the material.

[0037] During the rotation of the main crushing knife 4 driven by the rotating cutter shaft 2, the first main knife 42 can cooperate with the first auxiliary knife 32 distributed along the inclined surface of the auxiliary knife connecting section 31. Since there are different cutting angles between the first auxiliary knives 32, the contact between the material and the first auxiliary knife 32 and the first main knife 42 becomes more flexible and diversified, thereby achieving a multi-point cutting effect. This design can prevent the material from accumulating in a certain position, ensure that the material is evenly distributed in the entire tool system, and obtain more sufficient cutting and grinding.

[0038] Moreover, with the stepped arrangement of the first auxiliary knives 32, the material can be gradually refined when it passes through the coordinated cutting between multiple first auxiliary knives 32 and the first main knife 42, increasing the cutting and grinding opportunities of each first auxiliary knife 32. This progressive layer-by-layer cutting method enables the material to obtain a finer crushing effect in a short time.

[0039] Furthermore, due to the stepped layout of the first auxiliary knife 32, the material will not stagnate at a certain position when passing through the tool, but will be able to flow better along the surface of the tool, so that the material forms a stepped grinding effect between the first auxiliary knife 32 and the first main knife 42. This design helps to avoid concentrated accumulation of materials, ensures that the materials are evenly distributed in the tool area, and ensures that the materials are cut and ground multiple times during the processing process, thereby significantly improving the material processing efficiency.

[0040] Due to the inclined arrangement of the auxiliary blade connecting section 31, the cutting range of the auxiliary pulverizing blade 3 in the mixing shell 1 can be increased, thereby improving the cutting efficiency.

[0041] like Figures 1 to 5 As shown, the connecting portion 41 of this embodiment is arranged obliquely on the rotating blade shaft 2 so that the first main blades 42 are arranged in an inclined stepped manner on the connecting portion 41 .

[0042] Specifically, the connecting portion 41 is arranged on the rotating blade shaft 2 through an inclined design. This inclined setting changes the working angle and cutting direction of the crushing main blade 4, and can present different cutting angles and cutting forces during the rotation process. This setting changes the way the material contacts the first main blade 42, thereby improving the cutting effect and processing efficiency.

[0043] Specifically, based on the inclination of the connecting portion 41, multiple first main cutters 42 are arranged in a stepped manner, that is, the installation angle of each main cutter is slightly different, forming a progressive layout. This stepped layout enables each first main cutter 42 to exert different cutting forces on the material when rotating, thereby optimizing the overall cutting and grinding effect.

[0044] Driven by the rotating blade shaft 2, multiple first main blades 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 design enables each main blade to not only work independently, but also to gradually chop or refine the material through a continuously progressive cutting action, thereby avoiding problems such as material blockage or inadequate processing.

[0045] Furthermore, the plurality of first main cutters 42 can cut the material simultaneously and sequentially within the same rotation cycle, thereby ensuring that the material is fully processed and the cutting efficiency is greatly improved.

[0046] And due to the stepped arrangement of the first main knives 42, the material will be guided along the cutting area between multiple first main knives 42 and the first auxiliary knives 32 during the rotation process, avoiding the accumulation of material at a certain position. The material will be gradually dispersed and evenly guided to different tool areas for further processing. This optimized design effectively avoids uneven cutting or blockage caused by material accumulation.

[0047] The inclined arrangement of the first main cutters 42 and the stepped cutting enable each first main cutter 42 on the rotating cutter shaft to cut materials at different cutting angles, especially making it easier to handle hard materials (such as bones, nut shells, fruit cores, etc.). Through the continuous progressive cutting process, the materials will be gradually refined, ensuring that even hard materials can be completely crushed.

[0048] Through the design of tilting and step-wise arrangement, multiple first main knives 42 can share the cutting burden of the material during the rotation process, avoiding a first main knife 42 from being subjected to excessive pressure for a long time. In this way, the wear of the tool is evenly distributed, reducing the wear or damage of the tool caused by concentrated load, and extending the service life of the tool.

[0049] Moreover, with the stepped arrangement of the first main knife 42, the material can be gradually refined when it passes through the coordinated cutting between multiple first auxiliary knives 32 and the first main knife 42, increasing the cutting and grinding opportunities of each first main knife 42. This progressive layer-by-layer cutting method enables the material to obtain a finer crushing effect in a short time.

[0050] Furthermore, due to the stepped layout of the first main cutter 42, the material will not stagnate at a certain position when passing through the cutter, but will be able to flow better along the surface of the cutter, thereby forming a stepped grinding effect of the material between the first auxiliary cutter 32 and the first main cutter 42. This design helps to avoid concentrated accumulation of materials, ensures that the materials are evenly distributed in the cutter area, and ensures that the materials are cut and ground multiple times during the processing process, thereby significantly improving the material processing efficiency.

[0051] like Figures 1 to 5 As shown, the connection portion 41 of this embodiment is provided with a through hole 411, and the material can pass through the connection portion 41 through the through hole 411. The main purpose of providing the through hole 411 on the connection portion 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 connection portion 41, thereby avoiding the accumulation or retention of the material during the processing.

[0052] The design of the through hole 411 ensures that the material will not stay at the connecting portion 41 when passing through the tool, and can reduce the resistance of the material to the crushing main tool 4, avoiding unnecessary pauses or energy waste. The setting of the through hole can improve the smoothness of the system and reduce the burden of material accumulation on equipment operation.

[0053] like Figures 1 to 5 As shown, the rotary blade shaft 2 of this embodiment is further provided with a bottom wall stirring section 43 capable of stirring the material at the bottom of the stirring shell 1 , and the bottom of the bottom wall stirring section 43 is close to or against the bottom inner wall of the stirring shell 1 .

[0054] In terms of design, the bottom of the bottom wall stirring section 43 is close to or against the bottom inner wall of the stirring shell 1, so as to ensure that the stirring section can effectively contact the material at the bottom. During the rotation process, 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 the material at the bottom and mix it with the upper material to avoid stagnation or accumulation of the material at the bottom due to gravity, thereby ensuring that the material in the entire container can be fully cut and ground, ensuring the uniformity of stirring and cutting.

[0055] Specifically, the bottom wall stirring section 43 works together with the main knife and the auxiliary knife on the rotating knife shaft 2 to form a strong flow and cutting effect in the stirring shell. The bottom wall stirring section 43 can not only break the material deposits at the bottom, but also promote the continuous flow of materials in the stirring shell, thereby enhancing the contact between the knife and the material and improving the cutting and grinding effects.

[0056] like Figures 1 to 5 As shown, the bottom of the connecting portion 41 of the present embodiment is connected to the bottom wall stirring section 43, so that the bottom wall stirring section 43 can be driven by the rotating knife shaft 2 during the rotation process. After the bottom wall stirring section 43 is connected to the bottom of the connecting portion 41, the two become an integral collaborative working component, ensuring that the stirring section 43 can be in close contact with the bottom of the stirring shell 1, so that the material can be processed more evenly during the stirring and cutting process.

[0057] The bottom wall stirring section 43 stirs the bottom of the stirring shell 1 as the rotating blade shaft 2 rotates. This stirring section design makes it difficult for the material to settle at the bottom of the shell, preventing the material 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 during the entire rotation process.

[0058] The connection between the connecting part and the bottom wall stirring section improves the stability of the connecting part, making it more stable during the rotation process and less prone to shaking or imbalance. In this way, the connecting part and the bottom wall stirring section can more effectively stir the materials in the stirring shell 1, reduce the vibration during the operation of the equipment, and improve the overall working stability.

[0059] And adopting such a design makes the tool structure more compact.

[0060] like Figures 1 to 5 As shown, the connecting portion 41 of this embodiment includes a stirring arm 412 and a connecting arm 413, and the connecting arm 413 is respectively connected to the stirring arm 412 and the bottom wall stirring section 43, and the stirring arm 412 and the bottom wall stirring section 43 are staggered so that the connecting arm 413 is tilted, and the first main knife 42 is arranged on the side wall of the connecting arm 413.

[0061] Specifically, the connecting portion 41 is composed of a stirring arm 412 and a connecting arm 413, which cooperate with each other to enhance the stirring and fluidity 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 with the bottom wall stirring section 43. The advantage of this structure is that the connecting arm 413 can better contact with the material by being inclined, pushing the material to flow upward and outward, thereby ensuring uniform processing of the material.

[0062] The staggered design of the stirring arm 412 and the bottom wall stirring section 43 allows the material to be more stirred and processed at the bottom. The purpose of the staggered design is to avoid dead angles or excessive overlap between the stirring arm and the bottom wall stirring section, ensuring that the material flows more smoothly in the bottom area. At the same time, this staggered setting helps to guide the material to different areas of the entire equipment, thereby improving the efficiency of cutting and stirring.

[0063] The inclined design of the connecting arm 413 ensures that the angle between the stirring arm 412 and the bottom wall stirring section 43 is consistent with 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 and improve the processing efficiency.

[0064] Specifically, the first main knife 42 is arranged on the side wall of the connecting arm 413. This design can ensure that the first tool can effectively cut the material during the material flow process. The side wall position of the connecting arm 413 optimizes the angle and force of the first main knife 42 in contact with the material, thereby achieving a more efficient cutting effect. The design of the first main knife 42 enables the material to be quickly cut or ground when passing through, thereby improving the processing speed and effect.

[0065] Specifically, the inclination 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 knife 42 form an efficient material processing system. The material is fully stirred, cut and ground in the equipment. The whole process has a high degree of fluidity and uniformity, avoiding material retention, accumulation or insufficient processing. The synergy between the various parts can ensure that the material is processed quickly and evenly, thereby improving the overall work efficiency.

[0066] 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 blade shaft 2 .

[0067] like Figures 1 to 5 As shown, the first main knife 42 and the first auxiliary knife 32 of this embodiment are both knife bodies with a certain thickness, and the side walls of the knife bodies are both provided with certain cutting edges.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] In other embodiments, the first auxiliary knife 32 and the first main knife 42 are both blade structures; or, the first auxiliary knife 32 is a knife body with a certain thickness, and the first main knife 42 is a blade structure; or, the first main knife 42 is a knife body with a certain thickness, and the first auxiliary knife 32 is a blade structure; the appropriate design can be selected according to actual needs.

[0077] 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.

[0078] 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.

[0079] Preferably, the number of the main crushing blade 4 is at least one, and a suitable design can be selected according to demand.

[0080] like Figures 1 to 5As 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. The relative movement between the first main cutter and the first auxiliary cutter realizes the chopping action of the material through the contact of the blades of the two. Moreover, there is a grinding gap between the first main cutter and the first auxiliary cutter. The grinding gap makes the material further squeezed and rubbed between the first main cutter and the first auxiliary cutter after chopping, thereby realizing 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).

[0081] 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 it does 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.
