Municipal road cutting and joint filling device

Abstract

The invention discloses a municipal road cutting and filling device, which comprises a car body; a cutting wheel is arranged on the left side of the car body, and a first dust collecting cover is set on the outer side of the cutting wheel, and the first dust collecting cover passes through the first The bellows is connected with a vacuum box; the right side of the cutting wheel is provided with a brush strip; the right side of the brush strip is provided with a caulking agent injection gun. The present invention is equipped with a cutting wheel and a caulking agent pouring device, and completes the cutting of the road and the pouring of the caulking agent in one operation, with higher operating efficiency and better effect of filling the caulking agent; the present invention is provided with a brush strip The dust cleaning device matched with the dust collection cover and the dust collection box can efficiently collect the dust generated by cutting and clean the cutting seam efficiently, which not only protects the working environment and the health of workers, but also keeps the cutting seam clean and can be Fill the caulk directly to ensure the quality of the filling.

Description

technical field [0001] The invention relates to the field of municipal machinery, in particular to a municipal road cutting and filling device. Background technique [0002] The joints cut into concrete pavements are called 'condensation joints'. During the setting and hardening process of concrete, the hydration of cement releases a large amount of heat, which causes the temperature of concrete to rise; most of the hydration reaction of cement ends, and the temperature of concrete begins to drop. During the cooling process, the concrete has solidified and hardened, and the shrinkage caused by the cooling will cause the concrete to crack, and the direction of the cracks is relatively random, which seriously affects the quality and service life of the pavement. Therefore, generally 8 to 12 hours after concrete pouring (before the temperature of the concrete pavement begins to drop), shrinkage joints should be cut at a distance of 4 to 6 meters, and the cutting depth is about...

AI Technical Summary

Problems solved by technology

[0003] Traditional road cutting and caulking are performed separately, and the joint cutting machine and the caulking machine are used to operate separately. The traditional cutting machine uses water to reduce dust, which has a good dust reduction effect, but it is a waste of water resources. At the same time, the sewage in the working environment is cross-flowing, and at the same time, the sewage and dust are mixed into the slit just cut, and it is impossible to directly fill the joint sealant. It is necessary to use a high-pressure water gun and a compressed air gun to remove the debris in the slit. Clearing makes the seam wall dry and clean, increasing the workload and reducing the efficiency of the operation
