Abstract

The invention relates to a stepless adjustable vibration generator of a vibrating roller, which is used for a controller controlling a complete appliance. The controller is connected with a valve by a lead, and the valve is communicated with a hydraulic lock by a revolving joint arranged on a pipeline; the hydraulic lock is communicated with the stepless adjustable vibration generator by the pipeline, and the stepless adjustable vibration generator is connected with a transmission shaft. The invention utilizes the stepless adjustable vibration generator, and a fixed eccentric block and a movable eccentric block of the stepless adjustable vibration generator cause the center of gravity of the stepless adjustable vibration generator to deviate from a center line; the stepless adjustable vibration generator generates larger exciting force when a hydraulic motor drives the stepless adjustable vibration generator to rotate. The invention has the advantages of reasonable design, simple structure, high efficiency, large vibration force, and the like. The compaction effect is good and the roller compaction times are fewer when the invention is installed on a roller of a roll. The invention can be widely applied to rollers of rolls.

Description

technical field [0001] The invention belongs to the technical field of paving and repairing machines, tools or auxiliary equipment for pavement of roads or other similar structures, and in particular relates to vibration compaction machinery in construction machinery. technical background [0002] The vibratory roller relies on the combined action of the mass of the machine itself and the exciting force generated by the exciting device to reduce the internal friction between the particles of the pressed material, wedge the soil particles tightly, and achieve the purpose of compacting the soil. Vibratory compaction has the characteristics of concentrated static load and dynamic load combined compaction, and has the characteristics of strong compaction ability, good compaction effect and high production efficiency. [0003] So far, there are fixed type and step-adjustable type of vibrating wheel vibrating devices for vibratory rollers at home and abroad. The fixed type is a s...
