Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement, in particular to an asphalt pavement paving device. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. This type of pavement uses asphalt binder to improve the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is a high-grade pavement widely used in road construction.

[0003] A search revealed that Chinese patent application number CN213978456U discloses an asphalt pavement paving device comprising a paving box with running wheels fixedly mounted on all four sides of the bottom. A feed hopper, extending through the top of the box, is embedded in the center of the top of the box's interior. Connecting square rods are welded to the front and rear ends of the lower left sidewall of the box. Scraping plates are hinged to the left sides of the two sets of connecting square rods via articulated shafts. Sliding mechanisms are fixed to the tops of the front and rear ends of the right sidewall of the scraping plates. Cylinders are fixedly mounted above the two sets of connecting square rods and located on both sides of the lower left sidewall of the box. The left output ends of the two sets of cylinders are articulated to the two sets of sliding mechanisms via articulated shafts. This asphalt pavement paving device uses a PLC controller to activate the cylinders' extension and retraction, driving the scraping plates to rotate vertically about the left end of the connecting square rods. This allows the distance between the bottom of the scraping plates and the ground to be adjusted, thereby controlling the thickness of the asphalt concrete material being laid.

[0004] Although the above scheme can discharge auxiliary asphalt raw materials during use, there are still some shortcomings during use. During actual use, the second motor drives the second rotating shaft and the vibrating hammer to knock the guide plate. However, due to the high viscosity of the asphalt raw material, it is difficult for the asphalt raw material to flow downward due to the vibration force, so that the asphalt raw material is difficult to be discharged smoothly. The utility model proposes an asphalt pavement paving device. Utility Model Content
