[0030] Specifically, the mounting flange 2 is provided with a central through hole 3 , and mounting holes 4 are arranged in a circular array around the central through hole 3 , and the mounting holes 4 play a role in connecting and transmitting driving force.

[0031] Specifically, the base 50 and the drum outer ring 10, the drum support plate 11 and the drum inner ring 10.1, and the drum support plate 11 and the mounting flange 2 are fixedly connected to each other by metal welding. The chisel set 5 is composed of 36 chisel units arranged on the drum outer ring 10 in a circumferential shape, and each chisel unit includes a base 50 and a chisel 51 arranged on the base 50.

[0032] like Figures 2 to 4 As shown, three chisel groups 5 are arranged on the outer ring 10 of the drum, namely, group E, group F, and group G. Any two adjacent bases 50 in each chisel group 5 are arranged crosswise, forming a maximum cutting width W on the left and right, ranging from 50mm to 200mm, preferably 110mm in this embodiment; the drum 1 has a width W1, ranging from 30mm to 180mm, preferably 100mm in this embodiment; an outer diameter φB, ranging from 500mm to 1000mm, preferably 800mm in this embodiment; an inner diameter φA, ranging from 450mm to 950mm, preferably 860mm in this embodiment; and W>W1.

[0033] Specifically, the chisel units of each chisel set 5 are arranged in two rows in the rotation direction, and any two adjacent bases 50 in any row form a spacing W2 in the axial direction of the drum, and the size range is 6mm to 15mm; there is a minimum distance W3 between the left row base 50 and the left side 12 of the drum 1, and between the right row base 50 and the right side 13 of the drum 1, and the size range is 8mm to 10mm, preferably 9mm in this embodiment; the chisel set 5 has a maximum working diameter φC in the diameter direction, and the size range is 700mm to 1200mm, and the preferred embodiment is 1100mm, and the ratio of the maximum cutting width W to the maximum working diameter φC is less than or equal to 0.1. Angles γ1 and γ2 are respectively set between the central axis 51.1 of the left row chisel 51 and the left side 12 of the drum 1, and between the central axis 51.1 of the right row chisel 51 and the right side 13 of the drum 1, and the size range is between 5° and 45°, and the embodiment is selected according to specific needs.

[0034] like Figure 5 As shown, the chisel 51 is installed in a base 50 , and an alloy head 52 is provided on the top of the chisel 51 . The starting points of the maximum cutting width W and the maximum working diameter φC are both measured from the center point of the alloy head 52 .

[0035] like Figure 6 to Figure 7As shown, the center of the base 50 has a through base hole 50.1 with a central axis 51.1. A chisel 51 is installed in the base hole 50.1 by an external expansion method. A carbide head 52 is welded on the top of the chisel 51 by a brazing process, which is the part that directly breaks the ground material or ore. The rotor system is usually used in soil, paving roads and other occasions. Therefore, when the service life of the chisel 51 is reached, it needs to be replaced. The disassembly tool will move in the direction of arrow F, and the disassembly tool will eject the chisel 51 by hitting the tail surface 51.2 of the chisel.

[0036] The working principle of this embodiment is further described below: the base 50 is arranged on the cylindrical drum 1 according to a certain pattern, forming a side view of the cutting rotor. The disc rotor rotates rapidly around the arrow direction H, and the chisel 51 cuts and crushes the ground material or ore, so the cut material will be collected from both sides to the middle, and after being collected in the middle, it will be transported to the transmission belt of the mechanical equipment by the material receiving mechanism of the milling machine, and then transported to the material pile or transport truck. The trench excavated on the ground will be used to install infrastructure such as sewers, cables, and pipelines.

[0037] As can be seen from the above, the disc rotor in this case adopts a lightweight and high structural strength design. When equipped on a milling machine, it can improve the construction efficiency and quality of the project and reduce the impact on the environment and traffic. The use of a milling machine based on a disc rotor for grooving has the advantages of high efficiency, safety, environmental protection, and wide adaptability.

[0038] It should be noted that the drawings of this embodiment are all in a very simplified form and use inaccurate ratios, and are only used to conveniently and clearly assist in explaining the embodiments of the utility model.

[0039] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
