[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1: An energy-saving concrete paving equipment for municipal road construction, such as Figure 1 and Figure 2 As shown, it includes a support frame 1, a universal wheel 2, a DC motor 201, a mounting frame 3 and a leveling component. The support frame 1 is symmetrically arranged on the left and right. The bottom surfaces of the two support frames 1 are respectively symmetrically mounted with universal wheels 2 in a front-to-back rotatable manner. The universal wheels 2 will facilitate the movement of the device. The DC motor 201 is mounted on the universal wheel 2 on the rear side through bolts. The DC motor 201 will drive the device to move through the universal wheel 2 on the rear side. The mounting frame 3 is slidably mounted between the two support frames 1, and the mounting frame 3 is provided with a leveling component for leveling concrete.

[0028] like Figure 1 and Figure 2 As shown, the scraping assembly includes a guide block 401, a servo motor 402, a reciprocating screw rod 403 and a scraper 404. The guide block 401 is welded symmetrically on the front of the mounting frame 3, and the servo motor 402 is installed on the right side of the front of the mounting frame 3 by bolts. The reciprocating screw rod 403 is symmetrically and rotatably installed on the front of the mounting frame 3. The ends of the two reciprocating screw rods 403 close to each other are connected by a spline, and the right end of the right reciprocating screw rod 403 is connected to the output shaft of the servo motor 402 by a coupling. The servo motor 402 will drive the two reciprocating screw rods 403 to rotate, and the ends of the two reciprocating screw rods 403 close to each other are respectively threadedly connected with scrapers 404. The two reciprocating screw rods 403 will drive the two scrapers 404 to move on the concrete through the threads, thereby scraping the surface of the concrete. The two scrapers 404 are both slidably connected to the two guide blocks 401, and the scrapers 404 will move along the guide blocks 401.

[0029] like Figure 1 and Figure 9 As shown, it also includes a lifting component, which includes a connecting block 1001, a threaded rod 1002 and a handwheel 1003. The top surfaces of the two support frames 1 are respectively slidably installed with connecting blocks 1001, and the sides of the two connecting blocks 1001 close to each other are connected to the mounting frame 3 by welding. The connecting blocks 1001 will drive the mounting frame 3 to move synchronously, and the top surfaces of the two support frames 1 are respectively symmetrically connected to the threaded rod 1002 in a front-to-rear symmetrical rotation manner. The two connecting blocks 1001 are respectively threadedly connected to the two threaded rods 1002 on the same side. The threaded rod 1002 will adjust the height of the connecting block 1001 through threads, and a handwheel 1003 is welded to the top of each threaded rod 1002.

[0030] When concrete needs to be paved during municipal road construction, first pour the concrete on the road to be paved, then push the device to the starting point through the universal wheel 2, and then turn the hand wheel 1003 in sequence. The hand wheel 1003 will drive the corresponding threaded rod 1002 to rotate, and the threaded rod 1002 will drive the connecting block 1001 to move up or down through the thread, and the two connecting blocks 1001 will drive the mounting frame 3 to move synchronously, so as to adjust the height of the mounting frame 3 to adapt to paving concrete of different thicknesses. When the adjustment is completed, start The servo motor 402 is started, and the output shaft of the servo motor 402 drives the two reciprocating screws 403 to rotate. The two reciprocating screws 403 drive the two scrapers 404 to move back and forth along the guide block 401 in the directions of moving away from and approaching each other through the threads, thereby scraping the surface of the concrete to prevent concrete accumulation and ensure the flatness of the concrete surface. Then the DC motor 201 is started, and the DC motor 201 drives the device to move slowly along the direction of the concrete to be paved through the universal wheel 2 on the rear side, thereby starting the concrete paving construction.

[0031] Example 2: Based on Example 1, Figure 1 and Figure 3 As shown, it also includes a vibrating mechanism, which includes a vibrator 501, a support block 502, a guide rod 503, a return spring 504 and a connecting rod 505. The top surface of the mounting frame 3 is symmetrically fixed with a vibrator 501 by bolts. The vibrator 501 is used to eliminate bubbles in the concrete and make the concrete densely combined. The middle part of the rear side of the mounting frame 3 is connected by bolts to the support block 502. The guide rods 503 are symmetrically slidably installed on the support block 502. The guide rods 503 will move along the support block 502. Return springs 504 are respectively fixed between the two guide rods 503 and the support block 502. A connecting rod 505 is connected between the lower ends of the two guide rods 503 by bolts. The left and right ends of the connecting rod 505 are respectively connected to the vibrator 501 on the same side by bolts. When the guide rod 503 moves downward, the vibrator 501 will be inserted into the concrete through the connecting rod 505.

[0032] like Figure 1 and Figure 4 As shown, it also includes a fixed rod 601 and a rolling roller 602. The fixed rods 601 are symmetrically welded on the mounting frame 3. The rolling roller 602 is rotatably installed between the two fixed rods 601. The rolling roller 602 will roll the surface of the concrete flat. The rolling roller 602 is located behind the scraper 404.

[0033] like Figure 1 、 Figure 5 and Figure 6As shown, it also includes a transmission mechanism, which includes a fixed block 701, a rotating rod 702, a missing gear 703, a rack 704 and a pulley group 705. The middle of the top surface of the support block 502 is connected to the fixed block 701 by bolts. The front of the fixed block 701 is rotatably connected to the rotating rod 702. The missing gear 703 is welded symmetrically on the left and right sides of the rotating rod 702. The rotating rod 702 will drive the missing gear 703 to rotate synchronously. The front of the two guide rods 503 is respectively welded with a rack 704. When the missing gear 703 rotates, it will mesh with the rack 704 on the same side. The missing gear 703 will drive the guide rod 503 to move downward through the rack 704. The left and right ends of the rotating rod 702 are respectively fixedly connected to the pulley group 705. The other ends of the two pulley groups 705 are respectively fixedly connected to the rolling roller 602. When the rolling roller 602 rolls, the rotating rod 702 will be driven to rotate synchronously through the pulley group 705.

[0034] like Figure 1 and Figure 7 As shown, it also includes a sliding rod 801 and a screed plate 802. The sliding rod 801 is symmetrically connected to the rear of the mounting frame 3 in a sliding manner. The sliding rod 801 will move back and forth along the mounting frame 3. The rear ends of the two sliding rods 801 are connected to the screed plate 802 by bolts. The screed plate 802 will smooth the concrete to ensure the flatness of the paving, and the screed plate 802 is located behind the vibrator 501.

[0035] like Figure 1 and Figure 8 As shown, it also includes a connecting frame 901 and a return spring 902. The connecting frame 901 is symmetrically and slidingly connected to the guide block 401 on the rear side. When the two scrapers 404 move away from each other, the scrapers 404 will push the connecting frame 901 on the same side to move away from each other. The other ends of the two connecting frames 901 are respectively rotatably connected to the sliding rod 801 on the same side. When the two connecting frames 901 move, the sliding rod 801 will be pushed to move back and forth. Reset springs 902 are respectively fixed between the connection points of the two connecting frames 901 and the guide block 401.

[0036] As the mounting frame 3 moves, the rolling roller 602 will follow the rolling, thereby flattening the scraped concrete again to ensure the flatness and compactness of the concrete surface. As the rolling roller 602 rotates, the rolling roller 602 will drive the rotating rod 702 to rotate synchronously through the pulley sets 705 at both ends, and the rotating rod 702 will drive the two missing gears 703 to rotate synchronously. When the two missing gears 703 are engaged with the corresponding racks 704, the missing gears 703 will drive the racks 704 to move downward, and the two racks 704 will drive the corresponding guide rods 503 to move downward synchronously along the support block 502, the return spring 504 will be compressed, and the two guide rods 503 will insert the two vibrators 501 into the concrete through the connecting rod 505, and eliminate the bubbles in the concrete through the vibrators 501, so that the concrete is densely combined, its strength is improved, and the quality of the concrete components is guaranteed. When the missing gear 703 is not engaged with the rack 704, the return spring 504 will reset and drive the guide rod 503 back to the initial position. The guide rod 503 will drive the vibrator 501 to be pulled out of the concrete upward through the connecting rod 505, thereby coordinating the movement of the device and intermittently vibrating the concrete, thereby eliminating the bubbles in the concrete while paving, and ensuring the construction quality of the road.

[0037] When the two scrapers 404 move in the direction of moving away from each other, the scrapers 404 will contact the connecting frame 901 on the same side and push the corresponding connecting frame 901 to move in the direction of moving away from each other. The return springs 902 are compressed. As the two connecting frames 901 move, the two connecting frames 901 will push the sliding rod 801 on the same side to move backward along the mounting frame 3. The two sliding rods 801 will drive the screed plate 802 to move backward synchronously on the concrete. When the two scrapers 404 move in the direction of moving towards each other, after losing the pushing force of the scrapers 404, the return springs 902 will reset and drive the two connecting frames 901 back to their initial positions in the direction of moving towards each other. The two connecting frames 901 will pull the screed plate 802 forward again through the sliding rod 801, thereby driving the screed plate 802 to move back and forth on the concrete in a cycle, thereby smoothing the concrete again to ensure the flatness of the paving.
