[0002] At present, when leveling concrete pavement, roller leveling machines are usually used. Most of them use three-roller leveling machines including paddle lifting, compaction, and leveling. However, during the leveling construction process, there are still problems with poor leveling quality, such as wavy surface layers, uneven mortar, and stop grooves after stopping in the middle, and there will be a fuselage position at the starting end that cannot be constructed. Therefore, it is necessary to improve the existing concrete leveling machines. Therefore, the applicant, based on the experience of concrete pavement construction, has developed a machine that has better leveling quality for concrete pavements, and can avoid the problem of stop grooves and the problem of a fuselage position that cannot be leveled at the starting point. Summary of the invention

[0004] The present invention is achieved through the following technical solutions:

[0010] The spiral roller, the leveling roller, and the paddle lifting roller are rotatably mounted on the bottom of the suspension respectively;

[0011] The spiral roller, the leveling roller, the paddle lifting roller, and the vibrating rubbing plate are arranged in sequence from front to back;

[0012] A driving mechanism drives the spiral roller, the leveling roller and the paddle lifting roller to rotate.

[0013] One implementation method is that the driving mechanism includes a first driving mechanism and a second driving mechanism, the first driving mechanism drives the spiral roller and the leveling roller to rotate through a first transmission mechanism, and the second driving mechanism drives the paddle lifting roller to rotate through a second transmission mechanism.

[0014] One implementation manner is that the second driving mechanism and the second driving mechanism are respectively located at two ends of the suspension.

[0015] One implementation method is that both ends of the spiral roller, the leveling roller and the paddle lifting roller are rotatably mounted on the frame rod of the suspension through seat bearings.

[0016] One implementation method is that the two ends of the spiral roller, the leveling roller, and the paddle lifting roller are rotatably mounted on the suspension through adjustment components, and the adjustment components include an outer box with a lower opening, a lifting box located in a box cavity of the outer box, and a lifting adjustment screw; the outer box can be adapted to be fixed to the frame rod of the suspension;

[0017] The lifting box can move up and down along the box body of the outer box;

[0018] Part of the lifting screw rod rotatably passes through the upper box plate of the outer box through a bearing;

[0019] The lower part of the lifting screw is connected to the lifting box through a threaded connection;

[0020] The lower box plate of the lifting box is provided with seat bearings which are respectively connected to the two ends of the spiral roller, the leveling roller and the paddle lifting roller 4.

[0021] In one implementation, the rotation drive mechanism includes an electric telescopic rod.

[0022] One implementation method is that the height of the vibrating rubbing plate can be adjusted through a connecting component.

[0023] Based on the same inventive concept, the present invention also provides a concrete leveling machine, which includes a walking mechanism and the concrete leveling mechanism described above;

In addition, by means of the reasonable arrangement of the spiral roller, the leveling roller, the paddle roller, and the vibration rubbing plate, the problem of a shutdown groove and the inability to perform leveling construction at the starting position of the fuselage can be avoided.

[0030] The spiral roller uses propeller blades with opposite ends to spread the concrete while keeping the aggregate balanced. Compared with unidirectional propeller blades, it can avoid the concentration of concrete on both sides and avoid the impact on the bearings at both ends.

[0031] The present invention is more flexible to use, wherein the inclination angle or height of the spiral roller, the leveling roller and the paddle roller can be adjusted by fine-tuning the adjustment component, so that they can be better adjusted to adapt to road surfaces with different inclination angles or heights; and the suspension of the leveler can be lifted and lowered on the wheel frame by the lifting component, and the height of the leveling component can be adjusted by lifting the suspension as a whole, further improving the flexibility of use.

In actual application, the lifting screw 93 has a threaded section, and a threaded hole is provided at the top of the lifting box 92.

[0086] The suspension can be installed on the wheel frame by a lifting assembly. The lifting assembly includes a lifting mechanism 110 and a guide fixing assembly. The guide fixing assembly includes a guide rod 120 fixed to the wheel frame and a guide sleeve 130 fixed to the suspension. The guide rod is inserted into the guide sleeve.
