Description

Asphalt paving machine road surface clearance auxiliary device

Technical Field

The utility model relates to the technical field of asphalt production construction, in particular to an auxiliary device for cleaning a pavement of an asphalt paver.

Background

Asphalt pavement refers to various types of pavement made by incorporating road asphalt material in mineral material. The applicant is a large-scale enterprise specially producing various different types of pavement asphalt products, and after the asphalt products are produced, the applicant can still send technical personnel to cooperate with a construction unit to carry out pavement paving construction.

After the asphalt mixture is proportioned and stirred, the next procedure is to pave the asphalt mixture. Before paving the asphalt on the pavement, sundries on a pavement base layer must be removed, so that the pavement base layer is dry and clean. And then paving the asphalt mixture. In the paving process of the asphalt mixture, the paving process of the asphalt mixture paver is that an automatic dumping truck unloads the asphalt mixture to a hopper of the paver, then the mixture is conveyed backwards to a spiral paver through a chain conveyor according to the basic condition of the asphalt pavement, and the spiral paver evenly paves the mixture on the width of the paving belt along with the continuous forward movement of the paver.

Because the pavement construction is implemented in the open air, in the paving work process, impurities such as sand stones are rolled and sputtered by vehicles on a bypass lane or sundries are brought to the pavement to be paved due to weather reasons such as the fact that trucks scatter loaded materials or strong wind, and although a small amount of impurities cannot bring overlarge quality influence to the pavement quality after final paving. However, if the defect can be overcome, the paving quality of the whole pavement project can be effectively improved.
