Eccentric vibrating mechanism of vibratory roller

Abstract

The invention belongs to the technical field of vibratory rollers, more particularly relates to an eccentric vibrating mechanism of a vibratory roller. The eccentric vibrating mechanism comprises a vibrating shaft; the vibrating shaft is sheathed with a fixed eccentric block which rotates along with the vibrating shaft, the edge of the fixed eccentric block is provided with a movable eccentric block, and the fixed eccentric block is matched with the movable eccentric block to cause the vibrating mechanism to be in high-amplitude and low-amplitude vibrating states respectively. As the edge of the fixed eccentric block is provided with the movable eccentric block, when the vibrating shaft co-rotates and rotates reversely, the fixed eccentric block simultaneously co-rotates and rotates reversely along with the vibrating shaft and the movable eccentric block rotates under the drive of the fixed eccentric block, and the movable eccentric block is matched with the fixed eccentric block to realize the high-amplitude and low-amplitude vibrating states, thus causing the vibratory roller to be capable of better suiting road sections of different subgrades and greatly improving production efficiency of the vibratory roller. The eccentric vibrating mechanism also has simple structure and convenient production.

Description

technical field [0001] The invention belongs to the technical field of vibratory road rollers, and in particular relates to an eccentric vibration mechanism of a vibratory road roller. Background technique [0002] At present, the under-axis size of the eccentric quick mechanism of the vibratory rollers on the market is too large, which is not conducive to installation. In the actual construction process, the resistance to ramming is different for different road sections of the roadbed. If the ramming force is too large, It is easy to break the roadbed, the tamping force is too small, and it is not easy to stabilize the roadbed. Therefore, the vibratory roller needs to apply different amplitudes according to specific conditions. Obviously, the eccentric vibration mechanism of the existing vibratory roller can not meet the actual needs and needs to be improved. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an eccentric vibration mechan...

Problems solved by technology

[0002] The under-axis dimension of the eccentric fast mechanism of vibratory rollers on the market is too large, which is not conducive to installation. In the actual construction process, for different subgrade sections, the tolerance to tamping is different. If the tamping force is too large, It is easy to break the roadbed, the tamping force is too small, and it is not easy to stabilize the roadbed. Therefore, the vibratory roller needs to apply different amplitudes according to specific situations. Obviously, the eccentric vibration mechanism of the existing vibratory roller cannot meet the actual needs and needs to be improved urgently.
