Aiming at the problems, the invention aims to provide a rubber block rough crushing toothed roller of a waste heavy-duty tire casing crushing robot, which is characterized in that: comprises a roller, a key strip, a cutter wheel group and a prestressed ring anchor cable.

The shear blade on the roller surface of the roller is a cutter wheel group, the cutter wheel group transmits torque to the roller through a key strip, the cutter wheel group is formed by combining 10-20 cutter wheels, each cutter wheel is formed by four cutter heads, a high-low order cutter head is designed, 8-16 tooth blades are designed on the high-order part of each cutter head, a ring anchor and an anchor cable groove are designed on the low-order part of each cutter head, the ring anchor is divided into two areas, a tensioning end anchor cup and a fixed end heading anchor plate are respectively designed, an Ø 5 prestressed high-strength steel wire penetrates through the tensioning end anchor cup and surrounds the cutter wheel for a circle and then penetrates through the fixed end heading anchor plate to be cold headed into a heading, after the tensioning end anchor cup is provided with an anchor clamping piece, prestress ring anchor cables are formed after prestress is applied, the four cutter heads are fastened and combined into one cutter wheel, and the cutter wheels on the roller surface which are relatively rotated correspond to each other, so that two phases of the cutter wheels on the two rollers are staggered as the cutter wheels which are opened and closed in a reciprocating mode, and sheared on.

The inventors have found that a heavy duty tire is composed of a cover, an inner tube and a rim strip. The outer tire consists of three main parts, namely a tire body, a tire tread and a tire bead, wherein the tire body is formed by laminating a plurality of layers of rubberized cord fabrics according to a certain angle, and the cord fabrics are usually made of high-strength steel wires and synthetic fiber rubberized fabrics; the tread contacts with the ground and is made of heat-resistant and shear-resistant rubber materials; the tyre bead is used for tightly fixing the tyre on a wheel rim, and mainly comprises a steel wire ring, triangular filling rubber and steel wire ring wrapping cloth.

The inventor finds that after a tire body is cut into 3-4 cm rubber blocks, the rubber blocks are usually coated with vulcanized rubber and contain high-strength steel wire meshes, no matter the rubber blocks are recycled for the purposes of blending concrete, proportioning asphalt pavements, filling rubber products, preparing regenerated rubber and the like, the rubber blocks are firstly coarsely crushed into 5-mesh rubber blocks and then further finely crushed into 10-12-mesh rubber particles, and simultaneously steel wires are separated, namely the rubber blocks are crushed into 5-mesh rubber blocks in the coarse crushing stage, namely the rubber blocks with 5 meshes are further crushed into 10-12-mesh rubber particles in the fine crushing stage, namely the rubber blocks with 5 meshes are further crushed into 10-12-mesh rubber particles, because of the high elasticity of the vulcanized rubber, the mechanical energy of extrusion, impact, drilling and the like can be converted into elastic potential energy to do no work, the high-elasticity of the vulcanized rubber is preferentially considered to be suitable for a vulcanized rubber crushing process, the mechanical efficiency of a cutter head is the highest, the high-strength steel wire meshes are suitable for crushing, therefore, an open type double-roller crusher is adopted, the shearing blade upsetting roller is provided with the roller with the shearing blade disc with the shearing roller surface of which is a cutter head which transmits the torque to a roller through a keybar, the low-order cutter head is transmitted to the roller, the roller is formed by combining the cutter head of 10-20 cutter head, each cutter head is designed with four anchor wheel, the high-tension anchor-.

The inventor finds that the shearing edge on the roller surface of the roller is preferably considered to be suitable for crushing vulcanized rubber, and the high-strength shearing steel wire mesh is high in hardness and strength, so that the situation of shearing edge fracture is easy to occur, the reason is that the shearing edge bears larger impact force and extrusion force and also needs to balance larger torque during shearing, therefore, the prestress ring anchor cable is designed to tightly and fixedly connect four cutter heads into one cutter wheel.

The inventor finds that a cutter head is precisely cast by an investment mold, the material of the cutter head is preferably ZG270-500, annealing is carried out after casting forming, tempering is carried out after finish machining, the hardening and tempering hardness is HRC29-32, four cutter heads are sequentially assembled into a cutter wheel, a ring anchor of one cutter head is selected as a prestressing platform, a Ø 5 prestressing high-strength steel wire sequentially penetrates through a tension end anchor cup of the selected ring anchor, then penetrates through a fixed end upset anchor plate of the rest cutter head along an anchor cable groove, namely, a Ø 5 prestressing high-strength steel wire surrounds the cutter wheel for one circle, then penetrates through the fixed end upset anchor plate of the selected ring anchor, a hydraulic cold header is used for cold heading, then an anchor clamping piece is installed on the tension end anchor cup, anchor removing grease is uniformly coated to facilitate maintenance, a through-type hydraulic jack is used for applying prestressing, the applied prestressing is 60% of the strength of Ø 5 prestressing high-strength steel wire, four prestressing ring anchor cables are tightly fixed into a cutter wheel, then the cutter wheel is sequentially penetrated into a cutter wheel set according to form a high-strength cutter wheel, and the cutter wheel set, and the cutter wheel is sequentially connected with a cutter wheel set for a cutter.

Compared with the prior art, the invention at least has the following advantages: the shearing edge on the roller surface of the roller is preferably considered to be suitable for crushing vulcanized rubber, the high-strength shearing steel wire mesh sheet is high in hardness and strength, and the situation that the shearing edge is broken is easy to occur due to the fact that the shearing edge bears large impact force and extrusion force and large torque during shearing needs to be balanced.
