Description

Technical Field

[0001] The utility model relates to the technical field of roadbed maintenance, in particular to a push-type roadbed maintenance device for building highways. Background Art

[0002] With the continuous advancement of modernization, highway transportation, as an important part of the national economy, is particularly important in construction and maintenance. As an important part of the highway, the stability and durability of the roadbed are directly related to the safety and life of the highway. Therefore, regular maintenance and repair of the roadbed is an important measure to ensure the normal operation of the highway. In recent years, with the continuous development and innovation of engineering machinery technology, some new roadbed maintenance devices have begun to be applied in practice.

[0003] In the prior art, for example, the patent with publication number CN221072245U discloses a roadbed maintenance device, including a base, a storage barrel fixedly mounted on the upper surface of the base, a pressure plate slidably mounted on the inner wall of the storage barrel, two support plates symmetrically fixedly mounted on the top of the storage barrel, and a crankshaft rotatably mounted between the support plates. The utility model drives the crankshaft to rotate by driving a motor, so that the crankshaft drives the crank neck to rotate eccentrically, and drives the connecting rod to move by the crank neck, so that the connecting rod drives the pressure plate to move up and down along the barrel wall of the storage barrel. When the pressure plate moves downward, it can apply pressure to the inside of the storage barrel so that the internal caulking agent can be squeezed out. The caulking agent can be squeezed out quickly by this device, which speeds up the filling speed of road cracks.

[0004] Although the above patent solves the problem that the sealant is sticky and flows out slowly, which leads to a slow filling speed, the device cannot accurately control the amount of extruded material. The amount of material extruded each time is uncertain, and it is difficult to make targeted adjustments according to the size of the roadbed cracks and damaged surfaces, which easily leads to a waste of raw materials for maintaining the sealant. For this reason, the utility model provides a push-type roadbed maintenance device for building highways. Utility Model Content
