With the combination of the above embodiments, the using principle and working process of the present invention are as follows:

as shown in fig. 10, after the upper disc 301 and the lower disc 302 are fastened together in the crushing disc 15, the spiral grooves are reversely arranged, so that the blanking channel of the crushing disc 15 forms a sparse area (left-right direction) and a tight area (front-back direction), and the sparse area and the tight area are alternately arranged in the circumferential direction. The discarded object falls into behind the tight district card between last disc 301 and lower disc 302, is cut by cutting knife 303, and the discarded object falls into when sparse district by cutting knife 303 promote to the tight district cutting, that is to say the cutting of discarded object mainly concentrates on the tight district and goes on, and the clearance between the adjacent broken dish 15 is less, and the tight district is better to the effect of blocking of discarded object, and the discarded object is cut by cutting knife 303 more easily. As shown in fig. 10 and 12, in the initial state, the first fuse plate 304 overlaps the center line of the second fuse plate 305, and the center lines of the first fuse plate 304 and the second fuse plate 305 are offset from the midpoint of the compact area by a certain angle.

The motor 1 is started, the motor 1 drives the cutting knife 303 of the upper crushing part to rotate anticlockwise to cut waste through the upper shaft 201, and the lower shaft 202 drives the cutting knife 303 of the lower crushing part to rotate clockwise to cut waste under the driving of the upper shaft 201. The waste is thrown in from the feed inlet, and the bold waste is earlier through last crushing portion cutting breakage, and the broken waste of last crushing portion or the less waste of particle size of self get into the crushing portion breakage down, and the qualified waste of breakage discharges after the screen cloth screening, and the qualified waste of not breaking falls into return chute 11 through return material passageway 12 and gets into outer cylinder 6 again breakage under the effect of return material auger 9. Because the spacing between each broken dish 15 in the lower crushing portion is unchangeable, the final ejection of compact quality of discarded object is by lower crushing portion control, is convenient for adjust and control.

In the cutting and crushing process, if the material piling phenomenon occurs in the upper crushing part, the cutting resistance of the cutting knife 303 of the upper crushing part is increased, and in the cutting process, the cutting knife 303 can give an anticlockwise shearing force to the crushing discs 15 (here, the upper disc 301 and the lower disc 302 of the crushing discs 15) of the upper crushing part through waste materials, so as to drive the crushing discs 15 of the upper crushing group to rotate anticlockwise. Because of the fixed top of nodal pattern telescopic link 16, so the deformation takes place to the state that tends to vertically for the anticlockwise rotation of nodal pattern telescopic link 16 lower part, and the distance between 16 upper ends of nodal pattern telescopic link and the lower extreme increases, and the broken dish 15 of lower crushing portion wholly moves down, goes up the interval increase between each crushing board of crushing portion, and the clearance that the discarded object was blocked increases, is difficult to by the cutting, reduces the ejection of compact quality of crushing portion. Meanwhile, the change range of the lower part of the segmental telescopic rod 16 is larger than that of the upper part of the segmental telescopic rod in the process of changing towards the vertical state, and the counterclockwise rotation angle of the lower crushing disk 15 is larger than that of the upper crushing disk 15, so that the vortex groove on the lower disk 302 of the upper crushing disk 15 in the crushing disk 15 adjacent to the upper crushing part is gradually overlapped with the vortex groove on the upper disk 301 of the lower crushing disk 15, waste is more easily dropped into the lower-stage cutting disk from the vortex groove, the discharging speed of the upper crushing part is accelerated, the working load of an upper crushing group is reduced, and excessive wear of an upper cutter caused by forced cutting is reduced. Furthermore, during the counterclockwise rotation of the crushing disk 15 of the upper crushing portion, the rotation angle of the crushing disk 15 at the top of the lower crushing portion may be greater than that of the crushing disk 15 at the bottom of the upper crushing portion (because the rotation angle of the lower portion is greater than that of the upper portion when the nodal-shaped telescopic rod 16 approaches the vertical direction), at this time, the relative rotation of the first guiding plate 304 and the second guiding plate 305 may generate a movement dislocation, and simultaneously, due to the relative rotation of the first guiding plate 304 and the second guiding plate 305, the first guiding plate 304 rotates clockwise around its axis (as shown in fig. 13). Go up the discarded object of crushing portion and can fall with anticlockwise rotation when dropping, most discarded objects this moment can drop on first fuse board 304 and the anticlockwise decurrent inclined plane of second fuse board 305, the barrier effect when having reduced the discarded object whereabouts, guide more discarded object anticlockwise rotation, because the cutting knife 303 of crushing portion is clockwise rotation down, the discarded object can collide the cutting with the cutting knife 303 of crushing portion down, increase the shearing force of crushing portion cutting knife 303 down, with the crushing pressure of sharing crushing portion, avoid lasting the card and hinder.

Similarly, if the lower crushing portion is piled, the cutting resistance of the cutting knife 303 of the lower crushing portion increases, and the cutting knife 303 will give a clockwise shearing force to the crushing disks 15 (herein, the upper disk 301 and the lower disk 302 of the crushing disk 15) of the lower crushing portion through the waste during the cutting process, so as to drive the crushing disks 15 of the lower crushing portion to rotate clockwise. Because of the fixed top of nodal pattern telescopic link 16, so the lower part of nodal pattern telescopic link 16 rotates clockwise and takes place deformation to the state that inclines more, and the distance between 16 upper ends of nodal pattern telescopic link and the lower extreme reduces, and the broken dish 15 of lower broken group shifts up wholly, and the interval between each crushing board of going up broken group reduces gradually, and the clearance that blocks in the discarded object reduces, is blocked the cutting easily, and the cutting strength of crushing portion in the increase improves the ejection of compact quality of crushing portion. Meanwhile, the change range of the lower part of the nodular telescopic rod 16 is larger than that of the upper part of the nodular telescopic rod in the process of changing to a more inclined state, and the lower crushing disc 15 rotates clockwise by a larger angle than the upper crushing disc 15, so that the dislocation degree of the vortex groove on the lower disc 302 of the upper crushing disc 15 and the vortex groove on the upper disc 301 of the lower crushing disc 15 in the crushing plates adjacent to the upper crushing assembly is gradually increased, waste is not easy to fall into the lower-stage cutting disc from the vortex groove, the discharging speed of the upper crushing part is reduced, the working load of the lower crushing group is reduced, and the excessive abrasion of the lower cutter caused by forced cutting is reduced. Further, during the clockwise rotation of the crushing disk 15 of the lower crushing portion, the rotation angle of the crushing disk 15 at the top of the lower crushing portion may be greater than that of the crushing disk 15 at the bottom of the upper crushing portion (because the rotation angle of the lower portion is greater than that of the upper portion when the telescopic rod 16 moves to a more inclined angle), at this time, the relative rotation of the first material guiding plate 304 and the second material guiding plate 305 may generate a displacement misalignment, and simultaneously, due to the relative rotation of the first material guiding plate 304 and the second material guiding plate 305, the first material guiding plate 304 rotates counterclockwise around its own axis (as shown in fig. 14). Go up the discarded object of crushing portion and can fall with anticlockwise rotation when dropping, most discarded objects this moment can drop on first fuse board 304 and the clockwise decurrent inclined plane of second fuse board 305, increased the hindrance effect when falling to the discarded object, guide discarded object clockwise rotation, reduce blanking speed, because the cutting knife 303 of lower crushing portion is clockwise rotation, the discarded object can be with the cutting knife 303 syntropy motion of lower crushing portion, reduce the shearing pressure of lower crushing portion cutting knife 303, avoid lasting the card to hinder.

The device is divided into two stages for crushing by the upper crushing part and the lower crushing part, and the discharging quality and the discharging speed of the upper crushing part are adjusted by increasing or shortening the distance between the crushing discs 15 of the upper crushing part, so that the situations that the cutting knife 303 is excessively worn or other parts of equipment are damaged due to forced shearing when waste is accumulated in the upper crushing group or the lower crushing group are avoided. Further, through the setting of guide structure, when the card hinders taking place, first feed plate 304 and second feed plate 305 rotate relatively and first feed plate 304 overturns around self axis to the reasonable whereabouts of guide discarded object alleviates the cutting burden that the card hinders the position, avoids lasting the emergence that the card hinders, makes the atress of each cutting knife 303 more even reasonable, and the life of reinforcing device reduces certain cost of maintenance. In the crushing process, the drier 30 dries the crushed waste to reduce the moisture in the waste, and finally performs subsequent treatment on the waste by fermentation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
