Leveling mechanism of laser concrete spreader

The utility model discloses a leveling mechanism of a laser concrete spreader. The front part of a frame is connected with a support beam, the front part of the support beam is connected with a lifting beam, the front part of the lifting beam is connected with an auger device through a left lifting cylinder and a right lifting cylinder, a receiver support is fixed on the top parts of the lifting cylinders, a laser receiver is arranged on the receiver support, a scraper is arranged at a lower opening in the front surface of a box body of the auger device, the front end of the auger device is connected with a vibrating beam or a leveling plate which is provided with a vibrating motor, the support beam is provided with a level sensor and is hinged with the frame, and a leveling cylinder is connected between a leveling arm fixed on the support beam and the frame. The problems that the included angle between the vibrating beam or the leveling plate and the horizontal surface as well as the relative position of the laser receiver is not fixed, concrete can not be spread to edges and corners, multiple times of spreading are needed, an auger is worn, residues can not be discharged and the concrete spreading precision is different, are solved; the working performance of the spreader is ensured, the working efficiency and the leveling precision are enhanced, and the service life of the spreader is prolonged greatly by the adjustment on the auger.
