Description

Technical Field

[0001] This utility model relates to the technical field of construction equipment, specifically to a vibratory troweling scraper. Background Technology

[0002] A power trowel is a piece of equipment used in construction to level, compact, smooth, and polish concrete surfaces. It is commonly used in road construction, flooring, and building slab projects. A power trowel typically consists of an engine, transmission system, trowel assembly, and operating handle. It uses a rotating trowel (roller or grinding disc) to process the concrete surface, achieving a smooth, wear-resistant finish while promoting concrete strength development and surface hardening. To further enhance the leveling, smoothing, and polishing of the concrete surface, a scraper is usually installed at one end of the power trowel.

[0003] The fixed structure of existing power trowel blades makes it difficult to adjust their height when dealing with concrete of varying slumps, leading to over- or under-scraping and affecting surface smoothness. When handling concrete layers of different thicknesses, the fixed-height blades are ill-suited, resulting in areas where the slurry cannot be effectively lifted or leveled. Furthermore, for uneven surfaces, the non-adjustable angle of traditional blades makes it difficult to conform to complex surfaces, resulting in unevenness and insufficient compaction in the treated concrete. These defects not only reduce construction quality but also increase costs and time due to rework, failing to meet the high-precision and high-efficiency construction requirements of modern building projects. Utility Model Content

[0004] This utility model provides a vibratory trowel integrated scraper, which can solve the problem that the scraper of the existing trowel machine has a fixed structure and cannot flexibly adjust its height when facing concrete with different slumps, which easily leads to over-scraping or under-scraping.

[0005] A vibratory trowel includes a mounting base fixedly connected to a power trowel, a connecting mechanism, a troweling mechanism, and a vibration mechanism. The connecting mechanism includes a movable rotating plate and a mounting frame. One end of the movable rotating plate is hinged to the mounting base, and the other end of the movable rotating plate is hinged to the mounting frame. The troweling mechanism includes a scraper. The vibration mechanism includes a vibrating plate and a vibration source for generating vibration. Both the scraper and the vibrating plate are connected to the mounting frame. The scraper is located on the side of the mounting frame closer to the power trowel, and the vibrating plate is located on the other side of the mounting frame away from the power trowel. The vibration source is located on the top of the vibrating plate and at its center. The vibration source is an attached flat vibrator.

[0006] According to one embodiment of this utility model, the mounting frame includes a first frame, a connecting rod, and a second frame. The first frame is hinged to a movable rotating plate. The vibrating plate is disposed at the bottom of the first frame. One end of the connecting rod is hinged to the first frame, and the other end of the connecting rod is hinged to the second frame. The scraper is disposed at the bottom of the second frame. The mounting frame also includes a first telescopic rod, one end of which is hinged to the first frame, and the telescopic end of which is hinged to the top of the second frame. The first telescopic rod is an electric push rod.

[0007] According to one embodiment of this utility model, the vibration mechanism further includes a connecting cylinder, a fastening bolt, and a fastening nut. The connecting cylinder is disposed between the mounting frame and the vibrating plate. One end of the connecting cylinder abuts against the mounting frame, and the other end of the connecting cylinder abuts against the vibrating plate. One end of the fastening bolt passes through the mounting frame, the connecting cylinder, and the vibrating plate in sequence. The fastening nut is threadedly engaged with the fastening bolt. The connecting cylinder is made of an elastic material, specifically rubber.

[0008] According to one embodiment of this utility model, the connecting mechanism further includes a second telescopic rod, one end of which is hinged to the mounting base, and the telescopic end of which is hinged to the movable rotating plate. The second telescopic rod is an electric push rod.

[0009] The advantages of this utility model compared to the prior art are:

[0010] With the hinged structure of the movable rotating plate, the scraper can flexibly adjust its height and angle for concrete with different slumps, avoiding over- or under-scraping and ensuring that the surface flatness error is controlled within a very small range. It is especially suitable for the construction of highly fluid concrete or dry-hard concrete.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] First Embodiment

[0020] Please see Figures 1 to 3 As shown, a vibratory troweling scraper includes a mounting base 2 fixedly connected to a troweling machine 1, a connecting mechanism 3, a scraping mechanism 4, and a vibration mechanism 5. The connecting mechanism 3 includes a movable rotating plate 6 and a mounting frame 7. One end of the movable rotating plate 6 is hinged to the mounting base 2, and the other end of the movable rotating plate is hinged to the mounting frame 7. The scraping mechanism 4 includes a scraper 8. The vibration mechanism 5 includes a vibrating plate 9 and a vibration source 10 for generating vibration. Both the scraper 8 and the vibrating plate 9 are connected to the mounting frame 7. The scraper 8 is located on the side of the mounting frame 7 closer to the troweling machine 1, and the vibrating plate 9 is located on the other side of the mounting frame 7 away from the troweling machine 1. The vibration source 10 is disposed on the top of the vibrating plate 9 and is located at the center of the vibrating plate 9. The vibration source 10 is an attached flat vibrator.

[0021] It should be specifically noted that the above-mentioned power trowel 1 includes a frame 17, wheels 18, a vibrating rod 19 and a roller 20. The wheels 18 are fitted at the bottom of the frame 17, the vibrating rod 19 is located at the front end of the frame 17, and the roller 20 and the mounting base 2 are both located at the rear end of the frame 17.

[0022] When the power trowel 1 starts working, the wheels 18 drive the frame 17 forward. The front vibrator 19 first performs initial compaction and leveling of the concrete, followed by a secondary leveling by the roller 20. Next, the scraper 8 first contacts the concrete surface and, supported by the mounting frame 7, scrapes down any raised areas. Finally, the vibrator is activated to generate high-frequency vibration, which is transmitted to the concrete through the vibrating plate 9 for vibratory paving.

[0023] Specifically, the leveling mechanism 4 and the vibration mechanism 5 apply pressure and friction to the concrete surface sequentially to level any raised areas. Simultaneously, the height and angle of the leveling mechanism 4 and the vibration mechanism 5 can be adjusted via the connecting mechanism 3 to further improve the smoothness and gloss of the concrete surface. Specifically, the height of the leveling mechanism 4 and the vibration mechanism 5 can be adjusted by hinged connection between the movable rotating plate 6 and the mounting base 2; and the tilt angle of the leveling mechanism 4 and the vibration mechanism 5 can be adjusted by hinged connection between the movable rotating plate 6 and the mounting frame 7.

[0024] With the hinged structure of the movable rotating plate 6, the scraper can flexibly adjust its height and angle for concrete with different slumps, avoiding over- or under-scraping and ensuring that the surface flatness error is controlled within a very small range. It is especially suitable for the construction of highly fluid concrete or dry-hard concrete.

[0025] Second Embodiment

[0026] Based on the first embodiment, the mounting frame 7 includes a first frame 11, a connecting rod 12, and a second frame 13. The first frame 11 is hinged to the movable rotating plate 6. The vibrating plate 9 is disposed at the bottom of the first frame 11. One end of the connecting rod 12 is hinged to the first frame 11, and the other end of the connecting rod 12 is hinged to the second frame 13. The scraper 8 is disposed at the bottom of the second frame 13. The mounting frame 7 also includes a first telescopic rod 14. One end of the first telescopic rod 14 is hinged to the first frame 11, and the telescopic end of the first telescopic rod 14 is hinged to the top of the second frame 13. The first telescopic rod 14 is an electric push rod.

[0027] When the angle and position of the scraper 8 need to be adjusted due to different working conditions, the first telescopic rod 14 is activated. The telescopic end of the first telescopic rod 14 pushes or pulls the second frame 13. Since the second frame 13 is hinged to the first frame 11 through the connecting rod 12, under the force of the telescopic rod, the second frame 13 can rotate around the hinge point, thereby causing the scraper 8 to change its tilt angle. At the same time, the extension and retraction of the first telescopic rod 14 can also finely adjust the height of the scraper 8, making the contact between the scraper 8 and the concrete surface more precise. Through the coordinated operation of the first frame 11, the connecting rod 12, the second frame 13, and the first telescopic rod 14, the angle and height of the scraper 8 can be flexibly adjusted to adapt to different construction needs.

[0028] Third Embodiment

[0029] Based on the first embodiment, the vibration mechanism 5 further includes a connecting cylinder 15, a fastening bolt, and a fastening nut. The connecting cylinder 15 is disposed between the mounting frame 7 and the vibrating plate 9. One end of the connecting cylinder 15 abuts against the mounting frame 7, and the other end of the connecting cylinder 15 abuts against the vibrating plate 9. One end of the fastening bolt passes through the mounting frame 7, the connecting cylinder 15, and the vibrating plate 9 in sequence. The fastening nut is threadedly engaged with the fastening bolt. The connecting cylinder 15 is made of an elastic material, namely rubber.

[0030] A rubber connecting cylinder 15, acting as an elastic buffer, is sandwiched between the mounting frame 7 and the vibrating plate 9. When the attached plate vibrator is started and the vibrating plate 9 generates high-frequency vibration, the rubber connecting cylinder 15 can absorb and buffer part of the vibration energy, preventing the vibration from being directly and rigidly transmitted to the mounting frame 7 and other components of the power trowel 1. Simultaneously, fastening bolts pass through the mounting frame 7, the connecting cylinder 15, and the vibrating plate 9 in sequence, and are tightened with fastening nuts to firmly fix the vibrating plate 9 to the mounting frame 7. While ensuring connection strength, the elastic properties of rubber provide the vibrating plate 9 with a certain buffer space during vibration, optimizing the vibration transmission effect.

[0031] Fourth embodiment

[0032] Based on the first embodiment, the connecting mechanism 3 further includes a second telescopic rod 16, one end of which is hinged to the mounting base 2, and the telescopic end of which is hinged to the movable rotating plate 6. The second telescopic rod 16 is an electric push rod.

[0033] When the height of the leveling mechanism 4 and the vibration mechanism 5 needs to be adjusted, the second telescopic rod 16 is activated. The second telescopic rod 16, through its extension and retraction, pushes or pulls the movable rotating plate 6 to rotate around its hinge point with the mounting base 2. Since the other end of the movable rotating plate 6 is hinged to the mounting frame 7, this causes the mounting frame 7, the leveling mechanism 4, and the vibration mechanism 5 to rise or fall as a whole. By controlling the extension and retraction length of the second telescopic rod 16, precise adjustment of the scraper height can be achieved to adapt to the construction needs of concrete with different slumps and thicknesses.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
