Angle-adjustable tool magazine assembly for cold milling machine for asphalt pavement

Abstract

The invention discloses an angle adjustable type magazine tool assembly for a bituminous pavement cold milling machine. The angle adjustable type magazine tool assembly comprises a tool apron, a mounting seat and a base, and a milling tool mounted at the upper end of the tool apron, wherein the base is mounted on a milling roller of the bituminous pavement cold milling machine; the base is provided with an inclined T-shaped groove clamped with the mounting seat; the mounting seat is provided with a circular-arc groove; the tool apron is provided with a tool apron main body for stretching into the circular-arc groove; the tool apron main body is bonded with the groove wall of the circular-arc groove; the mounting seat is provided with a bolt connection part located at one side of the tool apron main body; the bolt connection part and the tool apron main body are connected through a tool apron connection bolt. The angle adjustable type magazine tool assembly can be used for adjusting an eccentric wear angle and a mounting angle of the milling tool so that the eccentric wear angle and the mounting angle are excellent matched angles, and furthermore, the milling tool is in the excellent working state.

Description

technical field [0001] The invention belongs to the technical field of milling and planing of asphalt pavement, and in particular relates to an angle-adjustable tool magazine assembly for a cold milling and planing machine of asphalt pavement. Background technique [0002] The operation performance and milling energy consumption control of the milling rotor of the asphalt pavement cold milling machine have always been the core content of the asphalt pavement milling technology research. Tool arrangement parameters such as the number of thread ends, pitch, and helix angle are the main factors affecting milling energy consumption and milling efficiency. Only reasonable milling rotor structure parameters, tool arrangement parameters and reasonable matching of each parameter can effectively improve milling performance and efficiency, reduce Milling resistance and milling energy consumption prolong tool life. [0003] The installation angle and eccentric grinding angle of the to...

AI Technical Summary

Problems solved by technology

[0004] Due to the lack of adjustable tool magazine components for milling rotors, the existing research on the tool installation angle and eccentric grinding angle of milling rotors is limited to simple theoretical analysis. Milling machine manufacturers just copy the tool installation parameters of existing models based on empirical parameters. It is often discovered during construction that the design of the tool installation angle and eccentric grinding angle is unreasonable, resulting in large fluctuations in milling load, reduced milling capacity, rapid tool wear and even damage to the tool seat; Adjust the installation angle and eccentric grinding angle, resulting in a certain degree of energy waste
