In some embodiments, a plurality of crushing teeth 21 are distributed on the inner wall of the crushing cylinder 5, and the length of the crushing teeth 21 corresponding to the position of the pushing plate 12 is greater than the length of the crushing teeth 21 corresponding to the position of the cutting blade 8, that is, the length of the crushing teeth in the region corresponding to the positions of the crushing cylinder and the pushing plate 12 is longer, and the length of the crushing teeth in the region corresponding to the positions of the cutting blade 8 is shorter. The cutting blades on each group of spiral blade units are spirally distributed, and the lengths of the cutting blades on each group of spiral blade units are changed along with the external dimension of the crushing barrel from top to bottom, so that the distance between the cutting blades at each position on the rotating shaft and the inner wall of the crushing barrel is gradually reduced. The inner wall of the crushing barrel is provided with the plurality of crushing teeth, and the length of the crushing teeth corresponding to the position of the push plate is larger than that of the crushing teeth corresponding to the position of the cutting blade, so that garbage materials form an S-shaped falling space in the crushing barrel from top to bottom, the crushing time of the garbage materials in the crushing barrel can be prolonged, and the purpose of improving the crushing efficiency can be achieved. Meanwhile, the whole garbage material which is vortex-shaped in the crushing barrel can be disturbed through the crushing teeth with longer size, so that the crushing effect is improved. The garbage materials are driven by the spiral blade to do centrifugal motion, the garbage materials with higher density are positioned on the outer layer, the garbage materials with lower density are positioned on the inner layer, and the lengths of the crushing teeth in the prior art are all consistent.
When the spiral conveying crushing device for garbage disposal is used, domestic garbage and medical garbage enter the crushing barrel from the feeding bin, the garbage materials are firstly cut and crushed under the action of the cutting pieces of the spiral blade unit, the garbage materials rotate in the crushing barrel under the driving action of the cutting pieces, and the garbage materials are contacted with the crushing teeth on the inner wall of the crushing barrel for crushing again; then the garbage materials gradually fall under the action of gravity and are sequentially crushed; when the rotating shaft rotates through the belt pulley, the driven shaft, the driving bevel gear and the driven bevel gear, the push rod moves up and down in the rotating shaft under the action of the belt pulley, the driven shaft, the driving gear, the driven gear and the crankshaft, and in the process of up-and-down movement, the push rod drives the push block to move up and down together and continuously change to extrude the slide block, so that the slide block continuously reciprocates on the rotating shaft along the through hole (namely reciprocates towards the radial direction of the rotating shaft), thereby driving the push plate to continuously reciprocate along the radial direction of the rotating shaft, when the periphery of the push plate is coated with flexible garbage materials, the wound flexible garbage materials are torn through the reciprocating motion of the push plate, and the flexible garbage materials are prevented from being wound on the rotating shaft; on the other hand, compared with the existing mode of cutting the flexible garbage materials wound on the rotating shaft by the blade arranged on the rotating shaft, the mode of extruding and tearing the push plate adopted by the invention does not have the problem that the blade is easy to damage because the blade is not arranged, the service life of the equipment is prolonged, and meanwhile, the maintenance cost is reduced.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Those skilled in the art can make various changes, modifications and equivalent arrangements to those skilled in the art without departing from the spirit and scope of the present invention; meanwhile, any changes, modifications and variations of the above-described embodiments, which are equivalent to those of the technical spirit of the present invention, are within the scope of the technical solution of the present invention.
