Detailed Description
As shown in fig. 1, the wear-resistant milling device comprises a support plate 1 and a left milling wheel 2 and a right milling wheel 2, wherein the two milling wheels 2 are rotatably arranged on the support plate 1, and the rock wall can be milled by the rotation of the two milling wheels 2 driven by a power source.
As shown in fig. 1 and 2, the milling wheel 2 includes a milling hub 20, a fixed milling cutter 21 and a swing milling cutter 22, the fixed milling cutter 21 is fixedly mounted on the milling hub 20, the swing milling cutter 22 is hinged on the milling hub 20, and a guide strip 3 capable of interacting with the swing milling cutter 22 is arranged on the support plate 1. When the milling hub 20 rotates, the fixed milling cutter 21 and the swing milling cutter 22 rotate along with the fixed milling cutter 21, the fixed milling cutter 21 can mill the space corresponding to the milling hub 20, and the swing milling cutter 22 can mill the space corresponding to the support plate 1. The oscillating cutter 22 is oscillated in order to avoid collision with the upper portion of the support plate 1 during rotation. When the swing milling cutter 22 comes to the lower part of the support plate 1, the guide strip 3 acts on the swing milling cutter 22 to enable the swing milling cutter 22 to be laterally arranged on the periphery of the support plate 1, so that the space corresponding to the support plate 1 can be milled; when the milling wheel reaches the upper part of the supporting plate 1, the guide strip 3 does not act on the swing milling cutter 22, and the swing milling cutter 22 returns to the outer side, so that the upper part of the supporting plate 1 is avoided, and the milling wheel 2 can normally rotate.
As mentioned above, friction between the guide strip 3 and the oscillating mill 22 occurs very frequently, and the thickness of the guide strip 3 determines the lateral angle of the oscillating mill 22, so that the wear resistance of the guide strip 3 is important. In order to improve the wear resistance of the guide strip 3, as shown in fig. 5, the guide strip 3 of the present invention is provided with a plurality of grooves 30 along the strip direction, and the grooves 30 are embedded with alloy columns. When the guide strip 3 interacts with the oscillating milling cutter 22, the oscillating milling cutter 22 acts on the alloy column, which has a greater resistance to wear and therefore greater wear resistance of the guide strip 3.
As shown in fig. 1 and 3, the swing milling cutter 22 includes a swing cutter seat 221 and a swing cutter head 220, the swing cutter head 220 can directly act on a rock wall to mill the rock wall, the swing cutter head 220 is mounted on the swing cutter seat 221, a support 222 is connected to the milling hub 20, the swing cutter seat 221 is hinged to the support 222, in order to allow the swing cutter seat 221 and the guide strip 3 to fully act, as shown in fig. 4, a contact protrusion 223 is provided on a surface of the swing cutter seat 221 facing the guide strip 3, and the contact protrusion 223 can act with the guide strip 3.
In order to make the space corresponding to the milling hub 20 have no milling blind area, the fixed milling cutters 21 are provided in a plurality, as shown in fig. 1 and 2, the fixed milling cutters 21 are arranged in equal intervals along the outer circumference of the milling hub 20 and are staggered in the axial direction of the milling hub 20. By this arrangement, the space corresponding to the milling hub 20 can be made to have no milling blind area.
Finally, it is worth mentioning that the fixed milling cutter 21 comprises a fixed seat and a fixed head, the fixed head being detachably mounted on the fixed seat. The fixed cutter head can be directly used on the rock wall to mill the rock wall.
