Description

Technical Field

Therefore, the structural construction of municipal roads is particularly important. During the construction of municipal roads, in order to ensure the flatness of the roads, asphalt paving work will be required. Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed into mineral materials.

[0003] The existing asphalt paving devices have the following problems: 1. After the asphalt is paved, some asphalt is easily adhered to the inner wall of the discharge pipe, and the asphalt will continue to flow downward, which is easy to cause waste and pollution to the road surface. At the same time, if the asphalt remaining on the inner wall of the discharge pipe is not cleaned in time, it is easy to cause the asphalt to solidify over time, affecting subsequent use; 2. Most of the asphalt discharge pipes are fixedly installed, resulting in the asphalt being laid only in a straight line and unable to expand the paving range, which causes the asphalt paving device to have to go back and forth for paving many times, which not only reduces the paving efficiency, but also makes the asphalt paving uneven.

When the latch 804 moves to a certain extent, the latch 804 blocks the rotating block 1002, and the rotating block 1002 can drive the hollow cylinder 803 to rotate through the latch 804, and the hollow cylinder 803 drives the pusher 801 to rotate through the disc 802. Since the pusher 801 is located in the slide groove 703 and is in sliding contact with the fan-shaped swinging member 701, the disc 802 drives the pusher 801 to rotate. 801 drives the fan-shaped swinging member 701 to perform reciprocating swinging motion with the rotating rod 704 as the rotating axis.
