[0015] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.
[0016] like Figure 1 As shown: A hanging auxiliary finishing device for a riding trowel, comprising a finishing scraper bar 1, which is connected to the tail of the riding trowel 2 through a fixed bracket. The bottom surface of the finishing scraper bar 1 is flush with the trowel surface of the riding trowel 2. When the riding trowel 2 is performing troweling operations, the finishing scraper bar 1 at the tail can directly assist in finishing the surface; the finishing width of the finishing scraper bar 1 is expanded on both sides compared with the trowel width of the riding trowel 1, ensuring that the trowel range of the riding trowel 2 is fully covered.
[0017] The fixed bracket includes a left connecting rod 3, a middle connecting rod 4 and a right connecting rod 5. The first ends of the left connecting rod 3, the middle connecting rod 4 and the right connecting rod 5 are connected to the surface scraping bar 1, and the second ends are connected to the driving type leveling machine 2 after passing through an intersection 6. The middle connecting rod 4 is diagonally reinforced by the left connecting rod 3 and the right connecting rod 5.
[0018] The scraping bar 1 is parallel to the connecting line of the two blade rotation axes of the riding type trowel 2.
[0019] The middle connecting rod 4 is perpendicular to the scraping bar 1 , and is connected at the midpoint of the length of the scraping bar 1 . The left connecting rod 3 and the right connecting rod 5 are symmetrical with the middle connecting rod 4 as the axis.
[0020] The scraper bar 1 is an aluminum alloy square tube. The top surface of the scraper bar 1 is connected to the left connecting rod 3, the middle connecting rod 4 and the right connecting rod 5 by bolts. The left connecting rod 3, the middle connecting rod 4 and the right connecting rod 5 are connected by bolts at the intersection 6. The driving type leveling machine 1 is connected to the left connecting rod 3, the middle connecting rod 4 and the right connecting rod 5 by bolts.
[0021] The scraper bar 1 is made of aluminum alloy square tube. Compared with the common scraper structure, it is light in weight and has little effect on the working stability of the driving type smoothing machine 2. The vertical surface of the aluminum alloy square tube can "carry" some mud to scrape the high parts of the concrete surface layer flat, and the mud in the high parts is "carried" to the concave parts for filling.
[0022] The left connecting rod 3, the middle connecting rod 4 and the right connecting rod 5 are divided into a long side and a short side at an intersection 6. The end of the short side is connected to the driving type leveling machine, and the end of the long side is connected to the finishing scraper 1.
[0023] The left connecting rod 3 and the right connecting rod 5 are angle steels, and the middle connecting rod 4 is a steel pipe. At the intersection 6, the left connecting rod 3 and the right connecting rod 5 are located on the upper and lower sides of the middle connecting rod 4.
