Description

TECHNICAL FIELD

[0001] The present application relates to the field of asphalt pavement paving equipment, in particular to an asphalt pavement construction tamper. BACKGROUND

[0002] The asphalt pavement tamper is an important equipment in road construction and maintenance, mainly used for compaction of asphalt mixture. Its core function is to quickly compact the loose asphalt material after paving to the designed density through high-frequency vibration or impact force, to ensure the flatness of the pavement and good bearing capacity.

[0003] One of the more common asphalt pavement tamper is driven by an internal combustion engine or motor to generate vertical high-frequency vibration or impact force. During operation, the tamper main plate is in close contact with the surface of the asphalt layer, and the energy is transmitted to the inside of the mixture to promote the rearrangement of aggregate particles and the expulsion of air, thereby improving the material density.

[0004] However, the inventors believe that the mechanism for generating high-frequency vibration or impact force used in most of these tamper machines is mainly an eccentric wheel driving a tamper hammer to link the tamper main plate to apply impact force. Although the overall tamper effect can be achieved, the mechanical damage to the parts directly related to the eccentric wheel may occur over time due to high-frequency vibration, greatly reducing the service life of the product.
