Description

Technical Field

[0001] The utility model relates to the technical field of roadbed construction, in particular to a roadbed filling construction device. Background Art

[0002] According to the different uses of roads, the thickness and materials of the roadbed are also very different when filling the roadbed. A roadbed of appropriate thickness can greatly extend the service life of the highway. The publication number is CN202020118822.0, which discloses a roadbed filling thickness control device. This device can effectively adjust the thickness of the roadbed during filling by adding a thickness control device to the machine, thereby improving the quality of roadbed filling. However, the device cannot adjust the width of the bulldozer push plate. If a wider soil pile is encountered, the soil needs to be pushed back and forth into the roadbed, which wastes a lot of time and increases the workload.

[0003] The publication (announcement) number is CN218711860U, which discloses a roadbed filling construction device, belonging to the field of roadbed technology, and it solves the problem that the existing filling device cannot freely adjust the width of the push plate. The roadbed filling construction device includes a vehicle body, a cavity is opened in the vehicle body, and a lifting mechanism is arranged in the cavity. The lifting mechanism includes a hydraulic telescopic rod 1, the hydraulic telescopic rod 1 is fixed in the vehicle body, a fixed block 1 is fixed at the bottom end of the hydraulic telescopic rod 1, an anchor rod is fixed at the bottom end of the fixed block 1, and the lower end of the anchor rod extends to the outside of the vehicle body, a hydraulic telescopic rod 2 is fixed at one end of the fixed block 1, a through slot is opened on the vehicle body, and the other end of the hydraulic telescopic rod 2 passes through the through slot and extends to the outside of the vehicle body, and a movable rod 1 is fixed to the other end of the hydraulic telescopic rod 2, and a fixed frame is fixed on the movable rod 1, and a push plate is fixed at the other end of the fixed frame. The utility model has the advantage that the width of the push plate can be freely adjusted.

[0004] Although the above scheme can freely adjust the width of the push plate, the adjustment of the push plate width requires the coordination of a large number of transmission structures such as motors, worm gears, worms, rotating shafts, rotating disks, movable rods, and hinges. The equipment width adjustment structure is complex and the operating cost is high. The push plate height adjustment requires the installation of hydraulic lifting components on the vehicle body, and the equipment height adjustment structure has high operating costs. Therefore, we propose a roadbed filling construction device. Utility Model Content
