Description

Technical Field

[0001] The utility model relates to the technical field of plate compaction, in particular to an asphalt premix road surface vibrating device. Background Art

[0002] After the asphalt pavement is paved, it will be further compacted and leveled by equipment such as rollers. At the same time, for some small areas or areas that cannot be leveled by rollers, a flat plate rammer will be used to compact and level the newly paved asphalt pavement. That is, a flat plate rammer is a tamping machine that uses an exciter to generate vibrations. It can increase the density of asphalt and make the paved asphalt pavement smoother and tighter.

[0003] For example, the Chinese utility model patent disclosed by publication number CN211547677U: a small flat plate rammer with rollers, this application designs a movable rolling device so that when the flat plate rammer is working, the rolling device is freely located behind the rammer, and does not affect the rammer's forward vibration and compaction of the ground. When the flat plate rammer is not working and needs to be moved, the rolling device is placed under the flat plate rammer, and the entire rammer can be moved forward and backward through the rollers. Although the roller can be flipped and moved by the rocker arm, when the roller is placed at the bottom of the equipment through the rocker arm mechanism, since the rocker arm has a certain structural length, it is necessary to lift one end of the equipment to a higher height through the armrest before the rocker arm can be placed at the bottom of the equipment. Similarly, when the roller is stored, it is also necessary to lift one end of the equipment. At this time, both hands need to lift one end of the equipment through the armrest, and since one end of the rocker arm is placed at the bottom of the equipment, it is not possible to easily move the roller out of the bottom of the equipment by flipping the rocker arm.
