Specifically, the rotary cutter shaft 2 is driven to rotate in the stirring shell 1 through a power source such as a motor and the like to drive the crushing main cutter 4 on the cutter shaft to rotate, so that kitchen waste in the stirring shell 1 can be effectively crushed by the plurality of first main cutters 42, moreover, through the staggered 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 are mutually matched, the materials are crushed into smaller particles due to the contact between the main cutters and the auxiliary cutters, a further cutting effect is formed, and when the first main cutters 42 rotate to the crushing auxiliary cutters 3, the crushed materials can enter the grinding gap 5 and are rubbed by the cutter bodies of the first main cutters 42 and the crushing auxiliary cutters 3, so that the materials are further ground. The grinding action can further refine the materials, so that a more thorough treatment effect is achieved.

In the whole working process, after the materials are cut by the main cutter and the auxiliary cutter, the materials are thinned into smaller particles through the grinding gaps among the cutters, and the grinding process can not only further refine the size of the materials, but also improve the treatment efficiency of the materials, and particularly has obvious advantages for the materials with higher moisture or difficult cutting (such as nut shells, bones and the like), can greatly reduce the size of the materials, and improve the efficiency of the subsequent treatment process (such as composting or biodegradation).

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 and the like) can be effectively ground into fine particles, and the processing effect of materials is improved.

And through the staggered design of the main knife and the auxiliary knife and the action of the grinding clearance, the material can be rapidly cut when passing through the knife, and can be further refined after being cut, so that the processing speed and the processing efficiency are improved, and the equipment can be used for processing a large amount of kitchen garbage more efficiently, and the processing time is reduced.

The three functions are fused through the cutter system, so that the work flow of the equipment is more compact and efficient, the traditional equipment can only realize the shredding function and cannot have the grinding function at the same time, and the equipment can refine materials when being shredded, so that the equipment can cope with rough machining and adapt to occasions needing high-precision crushing.

Due to the combination of the shredding and grinding functions, the shredded materials can be further thinned after entering the grinding gap, the decomposition process of the materials can be accelerated, the problem that the materials are stacked or difficult to process possibly occurring in the subsequent process is reduced, particularly when complex materials (such as bones and shells) are processed, the processing efficiency can be improved, and the shredding and grinding cooperation of the materials among the cutters can be effectively adapted to kitchen waste with different characteristics. Whether soft fruit and vegetable garbage or hard bones or dry and hard materials can be effectively treated through the cutter system, so that the equipment has higher adaptability in various application scenes.

As shown in fig. 1 to 5, the number of the crushing auxiliary cutters 3 in the embodiment is multiple, and the crushing auxiliary cutters 3 are arranged at intervals along the circumferential direction of the inner wall of the stirring shell 1, so that the material can be uniformly cut in the whole garbage treatment process, each auxiliary cutter can be contacted with the material at the inner wall of the stirring shell, under the driving of the rotary cutter shaft 2, the auxiliary cutters are matched with the rotary main cutter to form continuous cutting and grinding effects, and the distribution of the auxiliary cutters can effectively cover the whole treatment area, so that the chopping effect is enhanced.

And, smash pair sword 3 along circumference interval setting for the material can be constantly with pair sword contact at rotatory in-process, evenly distributed, and this kind of design can ensure that the material can not concentrate in a certain position and excessively cut or wear, but evenly receive the cutter effect, thereby improves holistic treatment effeciency.

The multiple arrangement of smashing vice sword 3 not only can smash the material when the material passes through smashing between main sword 4 and the smashing vice sword 3, can also make the material obtain refining through the dual action of cutting and grinding, smash vice sword 3 and also assist smashing main sword 4 to carry out more refining when smashing, smash vice sword 3's distribution can ensure that the inside material of stirring casing can both be effectively handled.

Furthermore, the crushing auxiliary cutters 3 are uniformly distributed along the circumferential direction of the inner wall, so that the materials can be uniformly cut and treated in the whole treatment process, the concentrated load is avoided, the cutter abrasion is reduced, the treatment efficiency is greatly improved by the design, and the high-efficiency treatment of the materials can be ensured particularly when a large amount of materials are treated.

Furthermore, the interval arrangement of the crushing auxiliary cutters 3 can promote the flow and distribution of materials, and the situation that the materials are accumulated at a certain position to cause incomplete treatment is avoided.

Further, after the plurality of crushing auxiliary cutters 3 are uniformly distributed, hard food residues such as bones, fruit pits, nut shells and the like can be cut more effectively, and the cooperation of the crushing auxiliary cutters 3 and the crushing main cutter 4 enables the hard objects to be crushed more fully.

Further, through distributing a plurality of crushing vice sword 3 at whole shells inner wall, reduced the load of single crushing vice sword 3, help reducing vibrations, noise and wearing and tearing in the equipment operation, the combined action of a plurality of crushing vice sword 3 also can make equipment operation more steady, improves the life and the operational reliability of equipment.

Further, since the plurality of crushing blades 3 share the processing load together, the cutter wear speed is relatively slow, reducing the frequent maintenance and replacement costs of the apparatus. Through the optimal design, the service cycle of the cutter is prolonged, and the complexity and cost of daily maintenance are reduced.

As shown in fig. 1 to 5, the auxiliary knife connecting section 31 of the present embodiment is disposed obliquely on the inner wall of the stirring housing 1 so that the auxiliary knife connecting section 31 is inclined at an angle with respect to the horizontal position of the stirring housing, and the plurality of first auxiliary knives 32 are arranged in a stepwise manner thereon, i.e., the installation angle of each first auxiliary knife 32 is gradually different, so that a stepwise arrangement is formed, and the angle and cutting manner of the first auxiliary knives 32 contacting the material are optimized, thereby enhancing the cutting and decomposing effects of the material.

In the process of rotating the cutter shaft 2 to drive the crushing main cutter 4, the first main cutter 42 can be matched with the first auxiliary cutters 32 distributed along the inclined surface of the auxiliary cutter connecting section 31, and as different cutting angles exist between the first auxiliary cutters 32, the contact between the material and the first auxiliary cutters 32 and the first main cutter 42 can become more flexible and diversified, so that the effect of multi-point cutting is realized.

Through the design of the inclination and the step arrangement, the plurality of first main cutters 42 can share the cutting burden of materials in the rotating process, and the situation that one first main cutter 42 bears excessive pressure for a long time is avoided. Therefore, the abrasion of the cutter is uniformly distributed, the abrasion or damage of the cutter caused by concentrated load is reduced, and the service life of the cutter is prolonged.

And, with the stepwise arrangement of the first main cutters 42, the material can be gradually thinned when passing through the cooperative cutting between the plurality of first auxiliary cutters 32 and the first main cutters 42, and the cutting and grinding opportunities of each first main cutter 42 are increased, so that the material can obtain finer crushing effect in a short time in a stepwise progressive cutting manner.

Moreover, due to the stepped layout of the first main cutter 42, the material does not stagnate at a certain position when passing through the cutter, but can better flow along the surface of the cutter, so that the material forms a stepped grinding effect between the first auxiliary cutter 32 and the first main cutter 42.
