Description

Technical Field

[0001] The utility model relates to the technical field of baffle material curtains, in particular to a front baffle material curtain for a paving machine. Background Art

[0002] When the asphalt paver is carrying out asphalt paving construction, the front side of the spiral feeding bin of the paver is not fully enclosed. When the front baffle is in the lowest position, there is still a gap of about 13 cm between the bottom of the front baffle and the ground. This gap will cause the slightly larger aggregates to separate from the mixture due to gravity and roll forward from the gap during the asphalt paving construction, forming a layered segregation of fine aggregates under the paving section, which directly affects the construction quality of the asphalt layer. After research, a 12 cm high rubber baffle was installed under the front baffle to solve the quality risk of aggregate stratification. However, because the baffle is made of rubber, it will not be easy to break under the high temperature of asphalt and equipment transfer. Due to the influence of scratches, the service life of the baffle is not long. Generally, it needs to be replaced every 2-3 months. In addition, the baffle damaged during asphalt paving construction may fall into the asphalt paving surface. If it is not discovered and removed in time, it will leave quality risks in the asphalt layer. When the paver is running, the baffle curtain will block the asphalt. However, when the baffle curtain is paving asphalt, the asphalt will adhere to the outer wall of the baffle curtain. When the construction is completed, there will be asphalt contamination on the outer wall of the baffle curtain. If it is not cleaned in time, it will be more difficult to clean after the asphalt solidifies, which will affect the subsequent construction and use.

[0003] In this solution, when the baffle curtain is used to block the material for the paver during paving, the baffle skin is made of rubber. Due to the high temperature of asphalt and the scratches during equipment transfer, the service life of the baffle skin is not long. Generally, it needs to be replaced every 2-3 months. In addition, the baffle skin damaged during asphalt paving construction may fall on the asphalt paving surface. If it is not discovered and removed in time, it will leave quality risks in the asphalt layer. In order to better block the material for the paver during paving, a front baffle curtain for the paver is needed to improve the above problems. Utility Model Content
