Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a fast seam cutting device for a traffic road surface. Background Art

[0002] The seams cut in concrete pavements are called expansion joints. During the process of concrete solidification and hardening, the temperature of the concrete begins to drop. During the cooling process, the concrete has already solidified and hardened. 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, expansion joints are generally cut after concrete pouring to prevent random cracks.

[0003] According to the patent application number CN201710618545.2, a fast road pavement cutting device for traffic includes a plate, wheels, a water spraying device, an adjusting device, a connecting block, a lifting rod, a second motor and a cutting blade. A wheel is provided at the bottom of the bottom plate, a water spraying device is provided on the left side of the top of the bottom plate, an adjusting device is provided on the right side of the top of the bottom plate, a connecting block is provided on the left side of the adjusting device, a lifting rod is provided at the bottom of the connecting block, a through hole is opened in the middle of the bottom plate, the lifting rod passes through the through hole, a second motor is installed at the bottom of the lifting rod, and a cutting blade is connected to the output shaft of the second motor;

[0004] In order to achieve a better dust reduction effect in the prior art, a dust suction device is usually added to the device. In order to prevent gravel from entering the dust suction pipe, a filter is generally provided at the end of the pipe body. Dust condenses on the surface of the filter when it meets water. After long-term use, the surface of the filter is easily clogged, which affects the subsequent dust suction effect. It is difficult to clean and protect the filter holes in time.
