the device comprises a frame 1, a frame 2, a support 3, rollers 4, a base plate 5, a ironing motor 6, a leveling plate 7, a rotating shaft 8 and a leveling motor.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments:

the utility model discloses a can carry out the concrete evener of flattening to concrete road surface. The following are specific examples:

a concrete screed, as shown in figures 1, 2 and 3, comprises a frame 1, a ironing section, a levelling section and a stand 2. The brackets 2 are provided at both ends of the frame 1. The lower end of the bracket 2 is provided with a roller 3 and a driving device for driving the roller 3 to move. Preferably, the driving device is a walking motor. The bracket 2 with the roller 3 can drive the whole device to move, thereby completing the operation of the whole road surface. A lifting device is arranged above the bracket 2. The fixed end of the lifting device is fixed on the bracket, and the telescopic end of the lifting device is connected with the frame 1 through a nut. The lifting device can adjust the height of the whole frame 1.

The ironing unit performs primary spreading and vibration of the concrete material, as shown in fig. 2 and 3. The ironing part is arranged in front of the bottom surface of the frame 1 and comprises a soleplate 4 and an ironing motor 5 with a vibrating action arranged above the soleplate 4. The base plate 4 is connected to the frame 1 by means of spring means.
