Description

TECHNICAL FIELD

[0001] The utility model relates to bituminous pavement maintenance equipment technical field, concretely is a bituminous crack filler. BACKGROUND

[0002] Most of the current highway pavement is the pavement with asphalt concrete as the surface layer, and crack is one of the common diseases of asphalt pavement. In order to improve the service life of the highway, crack filling equipment is usually used to fill and repair the cracks on the asphalt pavement.

[0003] For example, patent document application No. 202322136539.7 discloses a crack repair machine, which comprises a bottom plate and a mounting plate. The bottom end of the bottom plate is provided with a compaction assembly, which comprises a damper, a buffer spring, a compaction roller and a fixing seat. The bottom end of the mounting plate is fixedly installed with a plurality of dampers at equal distances. The compaction assembly is provided, and two electric push rods are started at the same time. The compaction roller can level the filled cracks. Under the action of the dampers and the buffer springs, the compaction roller is more closely attached to the pavement, improving the leveling effect of the compaction roller. The spiral blades are provided. The rotation of the stirring shaft drives the spiral blades to discharge asphalt. This not only avoids the blockage of the discharge pipe, but also realizes the continuity of the asphalt discharging, improving the efficiency of crack repair. The cleaning assembly is provided. The power motor is started, and the two cleaning racks drive the cleaning brushes to clean the asphalt adhered to the inner wall of the box.

[0004] However, due to the uncertainty of the depth and width of the pavement cracks, and the fact that the filling material will quickly solidify into blocks after being filled due to the influence of external temperature, the flowability of the filled filling material is poor. When using the above-mentioned crack repair machine to repair cracks, the discharge pipe is located above the crack to fill the filling material into the crack. If the crack is relatively deep, and the deepest part of the crack is usually relatively narrow, the crack in the narrow part may not be filled with filling material, resulting in a hollow at the lower end of the filled crack, thereby affecting the repair quality of the pavement. Therefore, we need to propose a bituminous crack filler to solve the above-mentioned problems, so that it can be inserted into the inside of the crack and filled with filling material from the inside of the crack from the bottom up, reduce the hollow phenomenon of the crack after repair, and improve the repair quality of the pavement.
