Composite amplitude modulating mechanism for vibrating compacting machine

Abstract

The invention discloses a composite amplitude modulating mechanism for a vibrating compacting machine. The composite amplitude modulating mechanism comprises a second base. A first base is arranged above the second base, four fixing blocks and supporting blocks are arranged above the first base, the supporting blocks are located in the middles of the four fixing blocks, flange plats are arranged above the fixing blocks, an amplitude modulating plunger pump is arranged above the flange plates, a vibrating compacting machine wheel is arranged above the amplitude modulating plunger pump, loop bars are arranged above the second base, damping springs are arranged in the loop bars, and connecting rods are arranged above the damping springs. The connecting rods, the damping springs and the loop bars are arranged, the damping springs are arranged in the loop bars, the connecting rods are driven to move downwards when the first base is pressed, the connecting rods drive the damping springs to be pressed, the damping springs achieve the effect of retarding vibration, and the problem that the damping effect of a composite amplitude modulating mechanism for the vibrating compacting machine isnot good is solved.

Description

technical field [0001] The invention belongs to the technical field of vibration compaction, and in particular relates to a composite amplitude modulation mechanism for vibration compaction machines. Background technique [0002] Vibration compaction is a kind of vibrating machine placed on the surface of the foundation for a certain period of time, using the shear compaction effect generated by its exciting force in the soil, so that the soil within a certain depth can be uniformly densified, thereby improving the mechanics of the foundation. Performance skills, the vibrating machine is placed on the surface of the foundation to vibrate for a certain period of time, and the shear compaction effect generated by the exciting force in the soil is used to uniformly densify the soil within a certain depth, thereby improving the mechanical properties of the foundation. It is suitable for treating sandy soil and loose miscellaneous filling soil (furnace ash, slag, broken bricks an...
