[0044] The implementation principle of a concrete pavement groove pressing machine in the embodiment of the present application is as follows: the staff first installs the support frame 3 on the low wall, and then installs the limit assembly 4 and the slide rail 2, uses the limit assembly 4 to fix the slide rail 2, and the support frame 1 is mounted on the slide rail 2, the pulley 15 is in rolling contact with the base rod 20, and the gear 61 is engaged with the rack 21; concrete is spread in the channel between the two low walls, the bottom surface of the pressing plate 5 is in contact with the top surface of the concrete, and the pressing strip 51 is inserted into the top surface of the concrete, and then the staff remotely drives the motor 60 to work, and the gear 61 is engaged and rolled on the rack 21, thereby driving the entire support frame 1 to move, and the flat plate vibrator 7 transmits vibration to the pressing plate 5 The pressing plate 5 vibrates and scrapes the concrete at the same time. Before the pressing plate 5 moves, the staff can also remotely control the electric push rod 85, which shrinks and causes the front side of the pressing plate 5 to tilt to a certain extent, thereby facilitating the movement of the pressing plate 5; when the groove pressing machine reaches the end of the movement, the drive motor 60 can be controlled to reverse and the electric push rod 85 extends, thereby driving the other side of the pressing plate 5 to tilt, and then the pressing plate 5 reverses to scrape the concrete pavement; during the entire working process, the concrete surface is significantly smoothed, the surface grooves are consistent and orderly, and have a good appearance. At the same time, the groove pressing machine replaces manual groove pressing, saving a lot of labor, reducing production costs, and improving construction quality and efficiency.
