The wheelbase of the wheel 12 is smaller than the width of the vibrating device 3 and the trowel plate 4, so that the traces left by the wheels 12 can be cleaned by the vibrating device 3 and the trowel plate 4. The leveling turntable 2 is located at the front side of the vehicle body 1, and the handle 11 is installed at the rear side of the vehicle body 1. The staff pulls the vehicle body 1 in a backward manner. A horizontal shaft 21 is set at the center of the leveling turntable 2. The horizontal shaft 21 is rotatably connected to the vehicle body 1.

A sliding sleeve 34 is fixedly provided on the leveling turntable 2. The guide rod 33 is used to be inserted into the sliding sleeve 34, so that the vibration head 32 can move vertically under the action of the guide rod 33, so that the vibration head 32 can vibrate the uneven parts to achieve flatness. The driving assembly 31 includes a cross bar 311, a spring 312 and a cam 313. The two ends of the cross bar 311 are respectively fixed to the upper ends of the two guide rods 33. The cam 313 is arranged above the middle part of the cross bar 311. The cam 313 is connected to a driving motor 314. The driving motor 314 is fixed on the leveling turntable 2.

[0032] The trowel plate 4 is located on the side of the vibration head 32 away from the vehicle body 1, and the middle part of the trowel plate 4 is fixed on the leveling turntable 2, so that the trowel plate 4 and the vibration head 32 are synchronously leveled, and the lower part of the trowel plate 4 is 2-5mm lower than the highest point of the vibration head 32, and 2-5mm higher than the lowest point of the vibration head 32. After the vibration head 32 vibrates the concrete, the trowel plate 4 smoothes the surface, thereby achieving the steps of leveling by the vibration head 32 and smoothing by the trowel plate 4, so that the surfaces of the leveling layer and the concrete layer are relatively flat, which helps to ensure the flatness of the waterproof layer and the finishing layer.

[0034] refer to Figure 3 A conveyor belt 7 is provided at the lower side of the vehicle body 1, and the lower side movement direction of the conveyor belt 7 is from the front of the vehicle body 1 to the rear of the vehicle body 1. When the scraper 6 scrapes excess concrete to the front side of the vehicle body 1, the rotation of the conveyor belt 7 can transport the concrete from the lower side of the vehicle body 1 to the rear side of the vehicle body 1. On the one hand, a large amount of concrete can be cleaned in advance by the conveyor belt 7, and suitable concrete can be reserved, and then scraped and leveled by the scraper 6, thereby reducing the pulling force required when the scraper 6 moves. On the other hand, the concrete scraped by the scraper 6 can be moved to the front side of the vehicle body 1 in time, so that the scraper 6 continues to level the concrete.
[0035] refer to Figure 4 A lifting platform 22 is provided inside the vehicle body 1. A driving device 8 for driving the horizontal shaft 21 to rotate is installed on the lifting platform 22.

The worm 83 is rotatably connected to the lifting platform 22 and coaxially fixed with the output shaft of the servo motor 81. The laser receiver 5 first receives the signal and transmits it to the processor, and then controls the rotation angle of the servo motor 81 through the processor. The worm wheel 82 is coaxially fixed on the horizontal shaft 21. The worm wheel 82 is meshed with the worm 83. The worm wheel 82 is driven to rotate by the worm 83, so that the horizontal shaft 21 rotates to rotate the leveling turntable 2, so that the vibration device 3 and the trowel plate 4 on the leveling turntable 2 rotate to maintain a horizontal position. The vibration of the vibration head 32 is transmitted to the horizontal shaft 21 through the leveling turntable 2, and then borne by the connection between the horizontal shaft 21 and the lifting platform 22, so as to reduce the impact of the vibration of the vibration head 32 on the servo motor 81 and reduce the service life of the servo motor 81.
[0036] A lifting device 9 for driving the lifting platform 22 to move up and down is provided below the lifting platform 22. A sliding rod 13 is fixedly provided inside the vehicle body 1. There are multiple sliding rods 13. The sliding rods 13 penetrate the lifting platform 22. Multiple sliding rods 13 can be arranged at the four corners of the lifting platform 22, so that the lifting platform 22 moves along the sliding rods 13. When the trowel plate 4 is adjusted to a horizontal position through the horizontal axis 21, the height of the trowel plate 4 also needs to be adjusted. After the height signal received by the laser receiver 5 is transmitted to the processor, the processor promptly transmits the signal to be adjusted to the lifting device 9, and the lifting platform 22 is raised and lowered through the lifting device 9, so that the trowel plate 4 can reach a suitable height.
[0037] The lifting device 9 includes two moving blocks 91, a driving screw 92 and a lifting motor 93. The lifting motor 93 adopts a stepping motor. The lifting motor 93 is fixed to the lower part of the vehicle body 1. The output shaft of the lifting motor 93 is coaxially fixedly connected with the driving screw 92.

The two moving blocks 91 are respectively located on both sides of the lifting platform 22, and the moving blocks 91 are provided with an inclined surface 95 on the side facing the lifting platform 22. The inclined surface 95 gradually moves away from the lifting platform 22 from bottom to top. When the two moving blocks 91 are close to each other, the inclined surfaces 95 approach each other and squeeze the lifting platform 22 to move upward, so that the position of the lifting platform 22 can be adjusted. A compression spring 96 is sleeved on the slide bar 13, one end of the compression spring 96 abuts against the lifting platform 22, and the other end abuts against the vehicle body 1. The force of the compression spring 96 is used to keep the lifting platform 22 in effective contact with the inclined surface 95. In order to reduce the friction between the lifting platform 22 and the inclined surface 95, a roller 97 is provided at the position of the lifting platform 22 close to the inclined surface 95, and the roller 97 abuts against the inclined surface 95.
[0038] The working process of this embodiment: The vehicle body 1 moves backward under the pull of the staff. During the movement, the two laser receivers 5 receive laser signals in real time to detect the horizontality of the vibration device 3 and the trowel plate 4. If there is a height difference between the two ends of the trowel plate 4, the horizontal axis 21 rotates under the action of the driving device 8 to lower the higher side of the trowel plate 4 and raise the lower side at the same time to make the trowel plate 4 reach the level. When the trowel plate 4 is in a horizontal state, the lifting device 9 adjusts the height of the lifting platform 22, so that the height of the trowel plate 4 can be adjusted to a suitable position. When the vehicle body 1 moves, the scraper 6 first cleans the excess concrete, and then vibrates the protruding sand and gravel through the vibration device 3 and moves downward, and then smoothes it through the trowel plate 4, thereby reducing the subsequent finishing and protecting the subsequent waterproof layer.
