Description

Technical Field

[0001] This utility model relates to the field of highway construction equipment technology, specifically a highway subgrade and pavement grooving equipment. Background Technology

[0002] After a highway is built and opened to traffic, its quality gradually deteriorates due to prolonged wear and impact from vehicle wheels, erosion and weathering from natural forces such as rainstorms, floods, wind and sand, snow, sun, and melting ice, as well as human damage and defects left over from construction. This leads to the appearance of marks, potholes, and other defects. To ensure the normal use of the highway and avoid disrupting traffic, any damage must be repaired and maintained promptly. Before repairing and maintaining the highway, grooving equipment is typically used to groove the roadbed and pavement. However, traditional grooving equipment often has its drive mechanism directly exposed on the top of the cart, making it susceptible to damage from flying stones or dust. Furthermore, the high-speed rotation of the disc saw during cutting generates friction with the ground, raising a large amount of dust, resulting in a poor working environment and potential impact on the surrounding environment. This invention proposes a new solution to these problems. Utility Model Content

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a highway subgrade and pavement grooving device, which has the following beneficial effects: 1. This utility model includes an engine, a square hole, a rotating shaft, a pulley, a belt, a disc saw, a protective shell, an air inlet, an exhaust fan, and a heat dissipation hole. Users can turn on the engine to rotate the pulley and rotating shaft, which in turn drives the disc saw to rotate, allowing for grooving of areas on the road surface that require repair and maintenance. The protective shell protects the outer end of the engine from damage caused by flying stones or dust. Users can also turn on the exhaust fan to accelerate airflow inside the protective shell for better heat dissipation. 2. This utility model includes a dust collection box, a fixed plate, an exhaust fan, a curved pipe, a dust collection hood, a coarse filter plate, a fine filter plate, a mounting groove, and an exhaust pipe. Users can turn on the exhaust fan to have the dust collection hood absorb the large amount of dust raised from the top of the circular saw, which then enters the dust collection box through the exhaust pipe. After being filtered by the coarse and fine filter plates, the dust is finally discharged through the exhaust pipe, thus solving the problem of dust pollution to the surrounding environment. Furthermore, users can open the door to disassemble the fine and coarse filter plates for easy cleaning. 3. This utility model includes a mounting frame, hydraulic cylinder, lifting plate, housing, motor, and drill bit. Users can turn on the motor to rotate the drill bit, and then control the hydraulic cylinder to make the drill bit drill holes in the road surface at intervals. This is convenient to use. Furthermore, the method of drilling holes before grooving can effectively protect the disc saw, make grooving easier, extend the service life of the disc saw, and reduce maintenance costs and resource consumption.
