Description

Technical Field

[0001] This invention belongs to the field of road construction technology, and more specifically, relates to a sustainable feeding device for a paver. Background Technology

[0002] Asphalt pavement has become the mainstream of highways, with mechanized construction accounting for the majority. Within this mechanized construction, the performance and structure of the on-site paving machinery have the greatest impact on the quality of asphalt pavement. During asphalt paving, segregation can occur due to factors such as loading / unloading and temperature control, resulting in segregation blocks or bands on the road surface. The continuity of the paving process allows asphalt to be laid onto the road surface as quickly as possible, reducing the probability of segregation. However, asphalt temperature continuously decreases during transportation and construction, leading to segregation. Furthermore, weather conditions such as rain causing road surface dampness necessitate a halt to construction to prevent asphalt and pavement from combining, directly impacting efficiency.

[0003] In the prior art, Chinese patent application number CN202310065084.6 discloses a continuous feeding device for a paver, including a frame and a conveyor belt installed on the frame and extending to the paver hopper to transport material. A buffer storage silo is provided on the frame at the front of the conveyor belt. The buffer storage silo has a discharge port and a buffer storage chamber. Material is poured into the buffer storage silo and stored in the buffer storage chamber. When the buffer storage chamber is full, it overflows and is discharged from the discharge port to the conveyor belt. The buffer storage chamber is opened during the alternating feeding of material from the trolleys, and material is discharged to the conveyor belt through the discharge port. The buffer storage chamber has… The solution has a material capacity to continuously discharge material to the conveyor belt during the alternating unloading of material trucks. Although this solution can achieve single-vehicle alternating unloading at a single point and maintain a continuous and uninterrupted feeding of material to the paver, if the asphalt stays in the storage bin and storage chamber for too long, the temperature of the asphalt will drop, directly affecting the asphalt's properties. This will lead to segregation when the asphalt is laid on the ground, directly affecting the construction quality and progress, reducing construction efficiency, and causing serious waste. Furthermore, this solution does not address the problem of asphalt paving being impossible due to road surface dampness or other reasons. Summary of the Invention
