[0017] like Figure 1 As shown, the vehicle body 1, at least two tire sets mounted on the vehicle body 1, each tire set including two coaxially arranged tires 12; a track 2 drivingly connecting the at least two tire sets; a plurality of trowel blades 4 uniformly covering the outer surface of the track 2 along the driving direction of the track 2; and a buffer 42 for reducing the disturbance of the concrete surface caused by the trowel blades 4 during the troweling process. One end of the trowel blade is hinged to the outer surface of the track 2, and the other end is connected to the outer surface of the track 2 through the buffer 42. Through the cooperation of the trowel blades 4, the track 2, and the buffer 42, the entire process of manual pressure troweling is simulated to complete the troweling and finishing process of the concrete.

[0018] Preferably, in this example, the vehicle body 1 is provided with a troweling power system 11 to drive the tires 12 to rotate, thereby driving the vehicle body 1 to move and smooth the surface. In this embodiment, the troweling power system 11 is driven by an electric motor, which generates less disturbance and achieves a better smoothing effect compared to the traditional technology that uses fuel.

[0019] As Figure 3 , Figure 4 shown, the trowel blade 4 is hinged to the surface of the track 2 by a hinge 41, and the buffer 42 comprises a buffer spring, one end of which is fixed to the outer surface of the track 2 and the other end of which is fixed to the inner surface of the trowel blade 4. In this embodiment, each buffer 42 comprises two buffer springs, one of which is shorter and closer to the hinge 41, and the other of which is longer and farther away from the hinge 41, so that the trowel blade 4 is inclined and can better smooth the protrusions on the concrete surface.

[0020] As Figure 1 , Figure 2 , Figure 4 shown, the trowel blade 4 is hinged to the surface of the track 2 by a hinge 41, and the buffer 42 comprises a buffer spring, one end of which is fixed to the outer surface of the track 2 and the other end of which is fixed to the inner surface of the trowel blade 4. In this embodiment, each buffer 42 comprises two buffer springs, one of which is shorter and closer to the hinge 41, and the other of which is longer and farther away from the hinge 41, so that the trowel blade 4 is inclined and can better smooth the protrusions on the concrete surface.

[0021] As Figure 1 , Figure 2 shown, each group of tires 12 is rotatably arranged on a wheel shaft, the two ends of the wheel shaft extend outward through the tires, and the cleaning blade 5 is fixed by two first connecting rods 31, which are respectively fixed to the two ends of one of the wheel shafts.

[0022] As Figure 1 , Figure 2 shown, the trowel blade 4 is hinged to the surface of the track 2 by a hinge 41, and the buffer 42 comprises a buffer spring, one end of which is fixed to the outer surface of the track 2 and the other end of which is fixed to the inner surface of the trowel blade 4. In this embodiment, each buffer 42 comprises two buffer springs, one of which is shorter and closer to the hinge 41, and the other of which is longer and farther away from the hinge 41, so that the trowel blade 4 is inclined and can better smooth the protrusions on the concrete surface.

[0023] As Figure 1 , Figure 2 shown, the trowel blade 4 is hinged to the surface of the track 2 by a hinge 41, and the buffer 42 comprises a buffer spring, one end of which is fixed to the outer surface of the track 2 and the other end of which is fixed to the inner surface of the trowel blade 4. In this embodiment, each buffer 42 comprises two buffer springs, one of which is shorter and closer to the hinge 41, and the other of which is longer and farther away from the hinge 41, so that the trowel blade 4 is inclined and can better smooth the protrusions on the concrete surface.

[0024] As Figure 1 shown, the trowel blade 4 is hinged to the surface of the track 2 by a hinge 41, and the buffer 42 comprises a buffer spring, one end of which is fixed to the outer surface of the track 2 and the other end of which is fixed to the inner surface of the trowel blade 4. In this embodiment, each buffer 42 comprises two buffer springs, one of which is shorter and closer to the hinge 41, and the other of which is longer and farther away from the hinge 41, so that the trowel blade 4 is inclined and can better smooth the protrusions on the concrete surface.

[0025] As Figure 1 , Figure 2As shown, two third connecting rods 33 are fixed on both sides of the rotation shaft of the roller 6, and the third connecting rods 33 extend forward and are fixed on both sides of the brush 7. By arranging the brush 7, the loose stones, water, garbage and other sundries on the concrete surface to be smoothed can be swept before smoothing, so as to facilitate the subsequent smoothing construction.

[0026] In the embodiment, as shown, Figure 1 The brush 7 comprises two-stage brushes.

[0027] In the embodiment, as shown, Figure 1 As shown, the operating rod 8 is fixed on the front of the vehicle body 1 and is used for controlling the advancing direction of the vehicle body 1.

[0028] In use, first, the vehicle body 1 is started to work, and the construction personnel stand in front of the vehicle body 1 and hold the operating rod 8 to control the advancing direction of the vehicle body 1. During the smoothing process, the concrete surface is sequentially smoothed by the brush 7, the roller 6 and the smoothing blade 4. Due to the arrangement of the buffer 42, the whole smoothing process is more stable, and the disturbance to the concrete surface is smaller.
