Detailed Description

Example one

Referring to fig. 1 to 5, the leveling device of this embodiment includes a leveling motor 32 disposed on a roller frame 31, a rotating shaft 33 having one end connected to the leveling motor, and a roller 36 having a scraping plate 34 and a material pushing plate 35 connected to the other end of the rotating shaft, the leveling motor drives the rotating shaft to rotate circumferentially through a transmission device 312, the scraping plate and the material pushing plate move relatively, the leveling device further includes a turntable 37 fixed at both ends of the roller and a cam groove 38 fixed on the roller frame, the turntable is connected to the cam groove through a bearing 39, the turntable, the cam groove and the roller are coaxially disposed and connected through the rotating shaft, at least one roller 310 capable of rolling along the cam groove is disposed in the cam groove, each roller is connected to one end of a material pushing shaft 311, the other end of the material pushing shaft passes through a through hole of the turntable and is connected to the material pushing plate on the roller, the leveling motor drives the roller to rotate circumferentially through the rotating shaft, the scraping plate scrapes the ground, and the rotary disc on the roller realizes synchronous circular motion, so that the material pushing plate on the scraping plate moves up and down relative to the scraping plate under the path of the cam groove, and the scraped residual concrete can be pushed away. The uneven concrete cloth that leads to of this application concrete leveling robot when the construction concrete cloth leads to the leveling ruler windrow too much to lead to the unable normal problem of advancing the construction of machine.
