Problems solved by technology

[0003] The amplitude of the roller is obtained by the eccentric moment / parametric mass of the eccentric block. After a roller is assembled, the amplitude of the existing roller can be adjusted. After the roller is compacted to a certain number of times, if the amplitude of the roller cannot be adjusted in time, the The compaction of this roller may cause the compacted surface to be overcompacted, and the compacted ground will be loosened, so that the compactness of the whole machine cannot meet the standard

Abstract

The invention relates to the technical field of engineering machinery, in particular to a road roller. The road roller comprises a vibrating wheel which is internally provided with a main vibration exciter and at least one auxiliary vibration exciter, a compactness detector which is used for detecting the compactness of a compacted pavement and is arranged on one side of the vibrating wheel, a transmission mechanism which is arranged in the vibrating wheel, is connected with the main vibration exciter and the auxiliary vibration exciter and drives the main vibration exciter and the auxiliary vibration exciter to rotate, a driving mechanism which is arranged in the vibrating wheel and is connected with the transmission mechanism, and an amplitude modulation mechanism which is used for adjusting the angle between the main vibration exciter and the auxiliary vibration exciter according to the pavement compactness. After the road roller is compacted to a preset number of times, the compactness detector can detect the pavement compactness, and the frequency modulation mechanism adjusts the angle between the main vibration exciter and the auxiliary vibration exciter according to the pavement compactness obtained through detection, so that the compaction range of the road roller is widened, and the situation that the pavement is over-compacted is effectively prevented.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a road roller. Background technique [0002] The existing road roller power transmission route is that the engine output power to the vibration pump, and then the hydraulic pressure is transmitted to the motor through the hydraulic pipeline, which drives the vibration motor to rotate, and then connects the vibration exciter through the vibration motor to form an eccentric force that drives the vibrating wheel to vibrate and to the roadbed Perform compaction. [0003] The amplitude of the roller is obtained from the bias moment / vibration quality of the eccentric block. After a roller is assembled, the amplitude of the existing roller can be adjusted. After the roller is compacted to a certain number of times, if the amplitude of the roller cannot be adjusted in time, then reuse The compaction of this roller may cause the compacted surface to be over compacted, which will l...
