Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a combined equipment for concrete paving and finishing. Background Technology

[0002] Concrete paving and smoothing is a very common construction process in the construction industry, and it is usually done manually or with the assistance of traditional machinery.

[0003] Concrete paving and smoothing operations suffer from drawbacks such as low efficiency, high labor intensity, and difficulty in controlling smoothing uniformity. Traditional methods often involve initial paving of concrete followed by smoothing by hand or simple machinery. In this process, the paving and smoothing steps are separated, which is not only time-consuming and labor-intensive but also makes it difficult to ensure consistent construction quality. Furthermore, traditional smoothing equipment often lacks flexible height adjustment functions for concrete layers of different thicknesses, resulting in unsatisfactory smoothing effects. Therefore, a combined concrete paving and smoothing equipment is proposed to solve the aforementioned problems. Utility Model Content

[0041] Beneficial effects:

[0042] This concrete paving and troweling combination equipment uses a first motor 3 to rotate the rotating rod 4 in both forward and reverse directions, which in turn drives the sliding plate 5 and the scraper 6 at the bottom to move back and forth horizontally to complete the initial paving of concrete. Subsequently, the leveling component is adjusted by using a second motor 9 to drive the linkage rod 12 and the connecting plate 21 to rotate. The scraper 23 at the bottom of the connecting plate 21 levels the concrete. At the same time, its height can be driven by a third motor 26 to drive the meshing transmission of the drive gear 15, the ring gear 14 and the driven gear 16, which drives the shaft 17 to rotate, thereby driving the adjusting column 18 to rise and fall in the guide cylinder 19, thus driving the arc-shaped slider 20 and the connecting plate 21 to be adjusted in the vertical direction, achieving flexible height adjustment.

[0043] Working principle:

[0044] The first motor 3 on the base plate 1 starts, driving the rotating rod 4 to rotate via its forward and reverse rotation. The external thread of the rotating rod 4 engages with the internal thread of the sliding plate 5, causing the sliding plate 5 and the scraper 6 fixed at its bottom to move back and forth horizontally under the guidance of the guide column 7, thus completing the initial paving of concrete. During this process, the rollers 8 on the connecting plate 2 assist in the movement of the equipment, ensuring the smooth progress of the paving operation. Subsequently, the second motor 9 starts, driving the linkage rod 12 and the connecting plate 21 installed at its bottom to rotate. Multiple circumferentially distributed scraper blocks 23 at the bottom of the connecting plate 21 smooth the initially paved concrete. At the same time, if adjustment is needed... The height of the scraper 23 can be adapted to concrete layers of different thicknesses. The third motor 26 can be started by the controller 24. The output end of the third motor 26 drives the drive gear 15 to rotate. The drive gear 15 meshes with the ring gear 14 and two symmetrically distributed driven gears 16 to drive the shaft 17 to rotate. Since the outer side of the shaft 17 is provided with a threaded section near the bottom end, and it cooperates with the threaded columnar groove on the top of the adjusting column 18, the rotation of the shaft 17 will drive the adjusting column 18 to rise and fall in the guide cylinder 19. The rise and fall of the adjusting column 18 will further drive the arc-shaped slider 20 and the connecting plate 21 to adjust in the vertical direction, thereby realizing a flexible height adjustment function.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
