Example Embodiment

[0022] Such as Figure 1 to Figure 6 Shown: a rotor tool holder assembly used on a road milling machine, which includes: a milling cutter base 2, a cutter sleeve 3, an elastic opening fastening sleeve assembly 5, and a cutter 4. The cutter sleeve 3 is fixed on the milling cutter base 2, and the milling cutter base 2 is welded to the milling cutter cylinder 1. The cutter sleeve 3 is a tubular body, and the outer circle of the cutter sleeve 3 is formed with a hook wrench groove 3-4, an open-end wrench surface 3-5 and a conical surface 3-3; the cutter sleeve 3 passes through the conical surface 3-3 and the milling cutter base The conical hole of the seat 2 is connected. The function of the hook head wrench slot 3-4 and the open-end wrench surface 3-5 is to facilitate installation and disassembly.

[0023] The cutter 4 is composed of a cutter bar 4-1 and a cutter head 4-2. The cutter bar 4-1 is installed in the inner hole of the cutter sleeve 3 through the elastic opening fastening...

Abstract

The invention discloses a rotor cutter seat component used on a pavement milling machine, and relates pavement maintenance machinery. A waist drum surface is manufactured on an outer circle of a cutter sleeve and is positioned on the outer side of a conical surface; an opening slot is axially formed in the waist drum surface; the maximum diameter of the slotted waist drum surface is 2-3 mm greater than the aperture of a milling cutter base matched with the slotted waist drum surface; the cutter sleeve is fastened to the milling cutter base under the action of elastic interference of the waist drum surface; and the cutter sleeve and the milling cutter base are connected in an own elastic tensioning manner, so that the cutter sleeve and the milling cutter base are tightly combined with each other and are convenient to mount and dismount. The impact of a pavement to a cutter head or a milling rotor can be buffered; damage and infirmness to elements, which are caused by over constriction, are avoided; and dust entering an inner cavity of the cutter sleeve from a gap of an elastic opening fastening sleeve component is discharged from the rear end of the milling cutter base, so that the rotation of a cutter rod cannot be influenced, and the service life of the cutter head is guaranteed.

Description

technical field [0001] The invention relates to a road surface maintenance machine, in particular to a rotor knife seat assembly used on a road surface milling machine. Background technique [0002] Road surface milling machine is the main equipment for road maintenance. The milling rotor rotates at high speed to mill and break the damaged asphalt pavement, cement pavement and various roadbeds, and then lay new road surface. [0003] The applicant applied for and granted the patent right on January 12, 2012. The utility model "Milling Rotor with Quick Tool Change Used on Road Milling Machine" (Patent Publication No. 202416142U), consists of the base layout of the road milling machine Two sets of left and right symmetrical, two sets of helical wires with opposite direction of rotation. The inner surface of the base is connected with each other to form two groups of auger-type helical blade chains with opposite rotation direction. The cut materials are concentrated to the mill...
