Preferably, the edge blade part 2 has a circumferentially symmetrical structure, which is beneficial to improve the cutting area and the cutting efficiency of the edge blade part 2.
In a preferred embodiment of the cold-recycling rotor of the present invention, as shown in fig. 3 and 4, the edge blade assembly 21 includes at least two edge blade assembly split bodies, each edge blade assembly split body includes an edge blade 211 and an arc-shaped plate 212, the edge blade 211 is fixed on the arc-shaped plate 212, the supporting mechanism 23 includes a ring sleeve, and the at least two edge blade assembly split bodies are inserted into the ring sleeve through the arc-shaped plate 212, so as to detachably mount the edge blade assembly 21 on the supporting mechanism 23.

Further, as shown in fig. 4, the arc-shaped plate 212 has a first radial positioning surface a, a first circumferential positioning surface C, and a first axial positioning surface E, the ring sleeve has a second radial positioning surface B, a second circumferential positioning surface D, and a second axial positioning surface F, the first radial positioning surface a and the second radial positioning surface B are in positioning fit, and the position of the arc-shaped plate 212 is defined in the radial direction r; the first circumferential positioning surface C is matched with the second circumferential positioning surface D in a positioning mode, and the position of the arc-shaped plate 212 is limited in the circumferential direction w; the first axial positioning surface E is matched with the second axial positioning surface F in a positioning way, and the position of the arc-shaped plate 212 is limited in the axial direction z; this achieves that the curved plate 212 is inserted into the sleeve, so that the curved plate 212 can effectively absorb the milling resistance in the direction of the drum axis 20. Still further, as shown in fig. 3 and 4, the edge knife assembly 21 further includes a bolt 213, and the arc plate 212 is fastened to the collar by the bolt 213, so that the arc plate 212 can be quickly detached.
As an improvement to the above embodiment, as shown in fig. 5, the edge cutter assembly includes a plurality of edge cutters 211, the edge cutters 211 are sequentially arranged from inside to outside at equal intervals in the circumferential direction and the axial direction of the arc-shaped plate 212, and the edge cutters 211 are located on the same straight line, so that the cutters sequentially cut into the road surface, and the rotor can be guaranteed to cut stably.
It should be noted that "inside" in the inside-out direction in the present invention refers to a position where the edge knife assembly is close to the drum 11, and correspondingly, "outside" refers to a position where the edge knife assembly is far from the drum 11, taking the embodiment shown in fig. 5 as an example, the edge knife assembly 21 is unfolded in the circumferential direction, and the at least two edge knife assembly split bodies include four edge knife assembly split bodies: the first side cutter assembly split body 21-1, the second side cutter assembly split body 21-2, the third side cutter assembly split body 21-3 and the fourth side cutter assembly split body 21-4, wherein the first side cutter assembly split body 21-1 is provided with a first group of side cutters 211-1, 211-2, 211-3 and 211-4; the second side cutter component split body 21-2 is provided with a second group of side cutters 211-5, 211-6, 211-7 and 211-8; the third blade assembly division body 21-3 has a third set of edge blades 211-9, 211-10, 211-11 and 211-12, and the fourth blade assembly division body 21-4 has a fourth set of edge blades 211-13, 211-14, 211-15 and 211-16, each set of blades being located on an arc-shaped plate 212. As shown in FIG. 5, in the same side cutter assembly split body, the intervals of adjacent side cutters in the axial z direction are all 2T, and the side cutters 211-1, 211-2, 211-3 and 211-4 are sequentially arranged outwards along the axial z direction to form a straight line, so that the cutters sequentially cut into the road surface, and the rotor is ensured to cut stably. The side cutters 211-1, 211-2, 211-3 and 211-4 of the first side cutter assembly split body 21-1 are respectively overlapped with the side cutters 211-9, 211-10, 211-11 and 211-12 of the third side cutter assembly split body 21-3 after rotating for 180 degrees along the rotor axis, the side cutters 211-5, 211-6, 211-7 and 211-8 of the second side cutter assembly split body 21-2 are respectively overlapped with the side cutters 211-13, 211-14, 211-15 and 211-16 of the fourth side cutter assembly split body 21-4 after rotating for 180 degrees along the rotor axis, namely, two cutters are arranged on the same section line, the cutting working condition of the side cutters is worse than that of a main milling cutter, and the cutting capability of the side cutters is favorably enhanced by arranging the two cutters at the same section line position.
As a further improvement to the above embodiment, as shown in fig. 5, two side cutters 211 that are axially close to each other in the split body of any side cutter 211 and the rest of the side cutter assembly are arranged in a staggered manner at equal intervals in the axial direction z, which is beneficial to increasing the cutting area of the side cutters and improving the cutting efficiency. Taking the embodiment shown in fig. 5 as an example, the distance between the side blade 211-6 of the second side blade assembly division 21-2 and the side blades 211-2 and 211-3 of the first side blade assembly division 21-1 in the axial direction z is T, so that the side blades have cutting capability at each position, and the cutting efficiency is obviously improved.
As a preference for the above embodiment, as shown in fig. 6, in the same edge blade assembly body, the cutting radii R of the plurality of edge blades 211 decrease in order in the direction from the inside to the outside. Taking the embodiment shown in fig. 5 and 6 as an example, the cutting radii R of the side blades 211-1, 211-2, 211-3, and 211-4 of the first side blade assembly division 21-1 are sequentially decreased, and the cutting radii R of the side blades 211-9, 211-10, 211-11, and 211-12 of the third side blade assembly division 21-3 are sequentially decreased, that is, the cutting radii R of the side blades close to the end surface of the rotor are smaller. Because the edge cutters 211-4 and 211-12 are positioned at the outermost edge of the rotor, the cutting working condition is the worst, and the cutting load of the edge cutters 211-4 and 211-12 can be effectively reduced by reducing the cutting radius so as to prevent the edge cutters from being worn too fast.
As a further preferable mode for the above embodiment, as shown in fig. 7, in the same edge blade assembly division body, the included angles β of the axes of the plurality of edge blades 211 with respect to the end surface of the arc plate 212 are sequentially increased in the direction from the inside to the outside. Taking the embodiment shown in fig. 7 as an example, the included angles β of the axes of the side blades 211-1, 211-2, 211-3, and 211-4 of the first side blade assembly body 21-1 with respect to the end surface of the arc-shaped plate 212 are sequentially increased from inside to outside, which is suitable for the position of the blade assembly in the axial z direction, and the side blades far away from the end surface of the rotor only need a smaller included angle β to ensure that the blade assembly is within the protection range of the side blades, and the smaller included angle β is beneficial to reducing the cutting resistance. Furthermore, as shown in fig. 7, the axis of any edge blade 211 forms a predetermined included angle with respect to the end surface of the arc plate 212, so that the blade seat of the edge blade 211 does not exceed the blade tip 2111 of the edge blade 211 in the axial direction, the entire edge blade 211 is ensured to be within the protection range of the blade tip 211, and the abrasion of the blade seat of the edge blade 211 by the road groove is avoided, so as to protect the edge blade.
The invention also provides a pavement cold recycling machine which comprises the cold recycling rotor. The cold regeneration rotor can prolong the service life of the rotor and save construction cost, and accordingly, the pavement cold regenerator also has the beneficial technical effects, and is not repeated herein.

For example, the blade assembly divisions may be provided in 3, 5, 6 or even more. It will be apparent to those skilled in the art that various changes, modifications, equivalents and variations can be made in these embodiments without departing from the spirit and scope of the invention.
