Abstract

The invention relates to a shearing type grinding cutter head for a kitchen waste processor. At present, when high-fiber kitchen residues (such as cane shoot shells) are treated, the treatment efficiency is low, and the treated fibers are overlong, the fibers are clustered and entangled with a cutter head, and even the outlet, the pipeline and the like are blocked. The invention relates to a shearing type grinding cutter head for a kitchen waste processor, wherein: the tearing edge and the crushing column are fixed on the movable disc, the movable disc is connected with the motor shaft through a square hole in the center of the movable disc, the fixed disc is arranged in the mounting groove on the inner side wall surface of the grinding cavity through the fixed teeth on the outer side surface of the movable disc, and meanwhile the lower surface of the movable disc is attached to the upper surface of the fixed disc. The device has the advantages that: the kitchen waste after preliminary crushing is continuously sheared when passing through a channel formed by holes of the two plates, the rotating speed of the motor is as high as thousands of revolutions per minute, the speed of the kitchen waste passing through the holes on the surfaces of the movable plate and the fixed plate is limited, and finally kitchen waste treated matters with small dimensions can be obtained.

Description

Shearing type grinding cutter head for kitchen waste processor

Technical Field

The invention relates to garbage disposal equipment, in particular to a shearing type grinding cutter head for a kitchen garbage disposal machine.

Background

Kitchen garbage processor is the electromechanical equipment that can carry out shredding with kitchen garbage, but at present when its processing high fiber class kitchen garbage (like cane shoot shell), treatment effeciency is low, and the fibre overlength after the processing, fibre agglomeration entangle the blade disc, and it is comparatively common to block up situations such as export and pipeline even, has not satisfied people's demand to kitchen garbage crushing effect.

Disclosure of Invention

(one) solving the technical problems

The invention aims to overcome the defects of the prior art, and provides a shearing type grinding cutter head for a kitchen waste processor, so that the processing efficiency can be greatly improved when the kitchen waste processor processes high-fiber kitchen waste, and the processed fiber is short enough to avoid agglomerating or blocking an outlet and a pipeline of the processor.

(II) technical scheme

The technical scheme of the invention is as follows: a shearing type grinding cutter head for a kitchen waste processor comprises a movable disc, a tearing edge, a crushing column and a fixed disc; wherein: the tearing edge and the crushing column are fixed on the movable disc, the movable disc is connected with the motor shaft through a square hole in the center of the movable disc, the fixed disc is installed in the installation groove on the inner side wall surface of the grinding cavity through the fixed teeth on the outer side surface of the fixed disc, and meanwhile the lower surface of the movable disc is attached to the upper surface of the fixed disc.

A shear-type grinding cutterhead for a kitchen waste disposer, wherein: when the kitchen waste processor adopting the scheme works, the motor rotates to drive the movable disc to rotate, the tearing edge and the breaking column on the motor perform primary breaking on kitchen waste through the effects of impact and the like, meanwhile, the movable disc and the fixed disc form a rotary scissor structure, and kitchen waste after primary breaking is continuously sheared when passing through a channel formed by holes of the two discs. The rotating speed of the motor is as high as thousands of revolutions per minute, the speed of kitchen waste passing through holes on the surfaces of the movable disc and the fixed disc is limited, and finally kitchen waste treated matters with small dimensions can be obtained.

(III) beneficial effects:

1. the area of the channel holes is large on the whole grinding disc, so that high shredding efficiency can be realized;

2. the speed of the garbage particles passing through the grinding disc is far smaller than the rotation linear speed of the movable grinding disc, so that the garbage particles passing through the grinding disc are cut to be small enough at one time, the process of further grinding is not needed, and the machine structure is greatly simplified.

3. Compared with the scheme of hammering and crushing kitchen wastes, the shearing scheme of the invention can obviously reduce the occurrence of machine clamping conditions and greatly prolong the service life of the grinding mechanism.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Embodiment 1 referring to fig. 1-2, a shearing type grinding cutter head for a kitchen waste processor comprises a tearing edge 1, a movable disc 2, a crushing column 3, a fixed disc 4, a motor shaft 5, a movable disc passage hole 6, a fixed disc passage hole 7 and a cross passage 8; wherein: when the kitchen garbage processor is assembled, the tearing edge 1 and the crushing column 3 are fixed on the movable disc 2, the movable disc 2 is circumferentially fixed with the motor shaft 5 through a square hole in the center of the movable disc 2, and the movable disc is axially fixed with the motor shaft 5 by using a nut. The fixed disk 4 is fixed in the mounting groove of the inner wall of the grinding cavity through the convex teeth on the outer side surface of the fixed disk, and simultaneously, after the machine is assembled, the lower surface of the movable disk 2 and the upper surface of the fixed disk 4 are in a mutually attached state.

Referring to fig. 2, when the kitchen waste processor using the scheme works, the motor rotates to drive the movable disc 2 to rotate, the tearing edge 1 and the crushing column 3 on the movable disc are used for primarily crushing kitchen waste through the effects of impact and the like, meanwhile, the movable disc 2 and the fixed disc 4 form a rotary scissor structure, and kitchen waste after primarily crushing is continuously sheared when passing through the cross channel 8 between the fixed disc and the movable disc. The rotating speed of the motor is as high as thousands of revolutions per minute, and the speed of kitchen waste passing through holes on the surfaces of the movable disc 2 and the fixed disc 4 is limited, so that kitchen waste treated matters with small dimensions can be finally obtained. According to actual needs, the width sizes of the movable disc passage holes 6 of the movable disc 2 and the fixed disc passage holes 7 of the fixed disc 4 can be changed during processing, the motor rotating speed is changed during the use of the garbage disposer, the size of the final kitchen garbage disposal object is controlled according to needs, and the popularization and application of the kitchen garbage disposal object are ensured not to cause the blockage of building pipelines or cause excessive pressure on a building septic tank.
