Dust-free excavator for hard concrete pavement

Abstract

The invention provides a dust-free excavator for a hard concrete pavement. The dust-free excavator comprises a main engine, a mechanical arm, a hydraulic pump station, a slitting milling mechanism, arotary motor, a water supply pump station, an air compressor, a plurality of ultrasonic air atomizing nozzles, cooling nozzles, a protective cover and a water supply pipeline, the slitting milling mechanism is mainly composed of coaxially connecting a left side milling roller, slitting blades and a right side milling roller; the protective cover is installed on the inner side of the mechanical armand located above the slotting milling mechanism at the same time, the ultrasonic air atomizing nozzles and the cooling nozzles are both installed on a fixing mechanism in the protective cover, the number and position of the cooling nozzles correspond to that of the slitting blades, the ultrasonic air atomizing nozzles are arranged above the left side milling roller and the right side milling roller, the ultrasonic air atomizing nozzles are connected with the water supply pump station and the air compressor correspondingly, and the cooling nozzles are connected with the water supply pump station. According to the dust-free excavator for the hard concrete pavement, safety, high efficiency, dust-free crushing, concrete slag removal and trenching of the concrete pavement can be realized, andthe advantages of high efficiency, large lumpiness, safety and little dust are achieved.

Description

technical field [0001] The invention relates to a dust-free excavator for hard concrete pavement, which is most suitable for crushing concrete pavement, removing concrete slag and digging trenches. Background technique [0002] Concrete refers to the general designation of engineering materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to the use of cement as cementitious material, sand and stone as aggregate, and water (may contain admixtures) and admixture) according to a certain proportion, the cement concrete obtained by mixing, also known as ordinary concrete, is widely used in civil engineering and road engineering. [0003] At present, with the rapid development of concrete pavement roads in my country, these roads are often partially damaged. The traditional repair method is to smash or mill the concrete pavement around the local damage with an impact pick. [0004] The impact pick breaking method will affec...

AI Technical Summary

Problems solved by technology

[0004] The crushing method of the impact pick will affect the strength and service life of the intact concrete pavement, and it takes a long time, has a low degree of mechanization, high labor intensity, and a large amount of dust

However, the tool wear of the single mechanical milling method is serious, the consumption is large, the dust production is large, and the environmental pollution is large, which greatly endangers the health of road workers.
