Description

Technical Field

[0001] This utility model relates to the field of road maintenance equipment, and in particular to an asphalt paving auxiliary screen and an asphalt paver. Background Technology

[0002] Current asphalt paving work typically involves using a towed asphalt paver to lay the road surface. The paving material used is usually a mixture of asphalt, gravel, and fine aggregate. Joints and edges often require manual patching to fill missing asphalt. However, directly using this asphalt mixture for patching can result in large aggregates becoming stuck in the road surface or joints, affecting the overall smoothness of the asphalt. In some paving operations, workers store a certain amount of asphalt mixed with small aggregate in separate containers specifically for manual patching during the paving process. However, because asphalt requires continuous heating, this method necessitates storing and heating both types of asphalt, significantly increasing the workload for workers and impacting paving efficiency.

It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.

[0018] like Figure 1 and Figure 2As shown, this utility model provides an auxiliary screen for asphalt paving, including a screen frame 1, a first screen 2, a second screen 3, and a base plate 4. The first screen 2, the second screen 3, and the base plate 4 are arranged sequentially from top to bottom on the screen frame 1. The first screen 2 is inclined, while the second screen 3 and the base plate 4 are horizontal. The mesh size of the first screen 2 is larger than that of the second screen 3. The bottom of the screen frame 1 is provided with a downwardly extending connecting rod 5, which can be detachably inserted into the connecting sleeve 6 of the asphalt paver.

[0019] During asphalt paving, the asphalt paving auxiliary screen can be installed on the paver's storage hopper and move synchronously with the paver. When encountering road edges or joints where additional fine asphalt material is needed, the asphalt mixture can be shoveled onto the first screen 2. The first screen 2 will screen the finer asphalt material onto the second screen 3. The second screen 3 will perform a second screening of the asphalt material. Workers can fill the required areas with asphalt material on the surface or bottom plate 4 of the second screen 3 according to the particle size requirements. It is convenient to use and has a wide range of applications.

[0020] In some specific embodiments, the mesh frame 1 is further provided with a storage box 7. The upper part of the storage box 7 is provided with a sliding groove 8, and the base plate 4 can slide along the sliding groove 8 to close or open the opening of the storage box 7. When the screened asphalt material needs to be used on-site, the base plate 4 can be inserted into the top of the storage box 7 to close the opening of the storage box 7. At this time, the asphalt material screened from the second screen 3 will fall directly onto the surface of the base plate 4, and the worker can use a shovel to shovel the asphalt material to a suitable position. If the base plate 4 is pulled out, the opening of the storage box 7 will be opened, and the asphalt material screened from the second screen 3 will fall into the storage box 7, making it easy to move the asphalt material as a whole to a predetermined area and then take it out of the storage box 7. The side of the base plate 4 is provided with a handle 9, which the worker can use to pull the base plate 4.

When independent use is required, the asphalt paving auxiliary screen can be directly pulled out from the connecting sleeve 6, making disassembly and assembly convenient. The pulled-out asphalt paving auxiliary screen can be moved via its own pulley 12.

[0025] The storage hopper 13 has a second discharge port 15 on one side. During asphalt paving, the storage hopper is towed by a special tractor. The spiral feeding roller 14 is connected to a motor and delivers the asphalt in the storage hopper 13 to the second discharge port 15, where it is laid on the ground. During asphalt paving, the asphalt paving auxiliary screen can be installed on the storage hopper of the paver and move synchronously with the paver. When additional fine asphalt is needed at the road edge or joint, the asphalt mixture can be shoveled onto the first screen 2. The first screen 2 separates the finer asphalt material onto the second screen 3, which performs a second screening. Workers can fill the required areas with asphalt material from the surface or base plate 4 of the second screen 3 according to the particle size requirements. This method is convenient to use and has a wide range of applications.
