[0024] When the paving machine needs to start working, the controller is operated according to the height of the concrete paving on site to make the hydraulic system output drive the support plate 1 to lift, the support plate 1 drives the screed 3 to lift through the rotating shaft to adjust to meet the screed operation of different height concrete, such as Figure 1As shown, the trowel plate 3 trowels the concrete, and the bottom surface of the trowel plate 3 is easy to adhere to the concrete after the trowel plate 3 is used. When the concrete on the bottom surface of the trowel plate 3 needs to be cleaned, the controller is operated to drive the driving assembly to work. The output end of the driving assembly drives the trowel plate 3 to rotate 90 degrees and then stop working. The bottom surface of the trowel plate 3 is gradually rotated to be attached to the inner arc surface of the arc-shaped scraper 4, so that the arc-shaped scraper 4 scrapes the concrete on the bottom surface of the trowel plate 3, as shown in Figure 4 As shown, the cleaning of the bottom surface of the trowel plate 3 is realized, and the arc-shaped scraper 4 protects the bottom surface of the trowel plate 3 at the same time, reducing the contact between the bottom surface of the trowel plate 3 and the external environment, and improving the service life of the trowel plate 3.

[0025] The bottom surface of the trowel plate 3 is an arc surface, and the circle where the arc surface is located coincides with the circle where the inner arc surface of the arc-shaped scraper 4 is located. The bottom surface of the trowel plate 3 is fully attached to the inner arc surface of the arc-shaped scraper 4 during the rotation of the trowel plate 3, so that the arc-shaped scraper 4 is convenient for cleaning the bottom surface of the trowel plate 3.

[0026] The length of the trowel plate 3 is equal to the length of the side of the chute 2, which improves the troweling width of the trowel plate 3 and effectively prevents the concrete from flowing out along the gap between the chute 2 and one end of the trowel plate 3.

[0027] Please refer to Figure 1 , Figure 2 , Figure 4 As shown, the driving assembly embodiment includes a three-phase asynchronous motor 6 fixedly connected to the side wall of the support plate 1 and arranged in the chute 2. The output end of the three-phase asynchronous motor 6 is fixedly connected with a gear 7. The lower part of the gear 7 is engaged with an arc-shaped rack 5, and the arc-shaped rack 5 is fixedly connected with the trowel plate 3.

[0028] Please refer to Figure 1 When the bottom surface of the trowel plate 3 needs to be cleaned and protected, the controller is operated to drive the three-phase asynchronous motor 6 to work. The output end of the three-phase asynchronous motor 6 drives the gear 7 to rotate, the gear 7 drives the arc-shaped rack 5 to rotate, and the arc-shaped rack 5 drives the trowel plate 3 to rotate counterclockwise by 90 degrees and then stop working, as shown in Figure 4 The three-phase asynchronous motor 6 has an automatic locking function, so that the output end of the three-phase asynchronous motor 6 cannot rotate. The three-phase asynchronous motor 6 cannot rotate, so that the gear 7 cannot rotate. The gear 7 cannot rotate, so that the arc-shaped rack 5 cannot rotate. The arc-shaped rack 5 cannot rotate, so that the trowel plate 3 cannot rotate, thereby improving the stability of the trowel plate 3.

[0029] When the trowel plate 3 needs to trowel the concrete road surface, the controller is operated to drive the three-phase asynchronous motor 6 to work. The output end of the three-phase asynchronous motor 6 indirectly drives the trowel plate 3 to rotate clockwise by 90 degrees and then stop, as shown in Figure 1 At this time, the trowel plate 3 is in a vertical state, and then the troweling operation of the concrete road surface is performed.

[0030] The top surface of the screed plate 3 is fixedly connected with a plurality of T-shaped rods 8, a sleeve 9 is slidably sleeved on the vertical rod of the T-shaped rod 8, the side wall of the sleeve 9 is fixedly connected with a horizontal rod 11, one end of the plurality of horizontal rods 11 is fixedly connected with a shovel plate 12, the side wall of the shovel plate 12 is attached to the side wall of the screed plate 3, a compression spring 10 is sleeved on the T-shaped rod 8, the compression spring 10 is arranged between the screed plate 3 and the sleeve 9 and is attached to the surface thereof, and the sliding groove 2 is provided with an arc-shaped plate 13 fixedly connected with one end of the arc-shaped scraper 4.

[0031] Please refer to Figure 1 , the side wall of the screed plate 3 close to the paver is easy to adhere to the concrete and needs to be cleaned during use, the controller is operated to make the driving assembly drive the screed plate 3 to rotate, the screed plate 3 drives the T-shaped rod 8 to rotate, the T-shaped rod 8 drives the sleeve 9 to rotate, the sleeve 9 drives the horizontal rod 11 to rotate, the horizontal rod 11 drives the rotation, the horizontal rod 11 drives the shovel plate 12 to rotate so that the top end of the shovel plate 12 gradually attaches to the inner arc surface of the arc-shaped plate 13, the arc-shaped plate 13 pushes the shovel plate 12 to gradually move to clean the side wall of the screed plate 3, the screed plate 3 drives the horizontal rod 11 to move, the horizontal rod 11 drives the sleeve 9 to move to extrude the compression spring 10 to deform, as shown in Figure 4 .

[0032] When the output end of the driving assembly drives the screed plate 3 to rotate clockwise by 90°, the screed plate 3 indirectly drives the shovel plate 12 to rotate and separate from the inner arc surface of the arc-shaped plate 13 at this time, the compression spring 10 pushes the sleeve 9 to move to reset, the sleeve 9 drives the shovel plate 12 to move through the horizontal rod 11 to gradually expose the bottom end of the side wall of the screed plate 3, as shown in Figure 1 .

[0033] The width of the shovel plate 12 is equal to the width of the screed plate 3, so that the side wall of the screed plate 3 can be fully cleaned.
