[0026] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0027] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.
[0028] See attached document Figures 1-6 This utility model discloses an asphalt compaction device, including a compaction frame 1, and further comprising: a power vibration device 2, which is mounted on the compaction frame 1, with a compaction block 3 screwed onto the lower end of the power vibration device 2, the power vibration device 2 being used to control the compaction block 3 to move up and down, thereby compacting the backfill material at the sampling hole; a cleaning device, which is set on the inner wall of the compaction frame 1, the cleaning device including a cleaning component, an electric telescopic rod 10, a transmission component, and a drive motor 15, the cleaning component being hinged to one side above the transmission component, the electric telescopic rod 10 being hinged to the bottom of the cleaning component and one side below the transmission component, the drive motor 15 being mounted on the compaction frame 1 with screws, and its output end being connected to the transmission component, for driving the transmission component to rotate, so that the cleaning component and the electric telescopic rod 10 rotate horizontally, cleaning the bottom of the compaction block 3; and a power supply device 4, which is fixed to the top of the compaction frame 1, for supplying power to the power vibration device 2 and the cleaning device.
[0029] Specifically, the compaction frame 1 includes an upper panel and support columns. There are three support columns arranged in a circular array along the outer periphery of the upper panel. The support columns are in an inverted L-shape. There are also three cleaning devices arranged in a circular array. The cleaning devices are installed inside the support columns. Brake wheels 6 are installed at the bottom of the support columns for moving the entire device. The power supply device 4 is located at the top of the connection between one of the support columns and the upper panel. A switch 5 is installed on the upper panel for controlling the start of the device.
[0030] In this embodiment, the upper panel and the support column are an integral structure. The brake wheel 6 is installed at the bottom of the support column by screws. The device is moved to the outside of the sampling hole to be compacted by the brake wheel 6. The brake component of the brake wheel 6 is stepped on, so that the device stops at this position. The switch 5 is pressed to connect the power device 4 with the power vibration device 2 and the cleaning device. The power vibration device 2 controls the compaction block 3 to move up and down to compact the backfill at the sampling hole. After the compaction block 3 moves up, the three cleaning devices operate in sequence to clean the backfill stuck to the bottom of the compaction block 3. Then the compaction block 3 moves down again, and the operation is repeated.
[0031] Specifically, the cleaning component includes a scraper 7, a connecting plate 8, and a limiting block 9. The scraper 7 has a dovetail-shaped cross-section, and its upper surface is in contact with the bottom of the compaction block 3. The scraper 7 is slidably connected to the connecting plate 8, and a groove adapted to the connecting plate 8 is provided at the bottom of the scraper 7. The limiting block 9 includes a stop part and a connecting part. The stop part is fixed to one end of the connecting part, and the connecting part is threadedly connected to the end of the connecting plate 8 near the compaction block 3. The stop part is located outside the connecting plate 8 and the scraper 7 near the compaction block 3 and is in contact with the scraper 7.
[0032] In this embodiment, the transmission component drives the scraper to rotate horizontally, causing one side of the scraper 7 to move from one side of the compaction block 3 toward the compaction block 3. The upper surface of the scraper 7 gradually contacts the bottom of the compaction block 3, scraping away the backfill material adhering to the bottom. When the scraper 7 rotates in the opposite direction, the other side of the scraper 7 moves from the other side of the compaction block 3 toward the compaction block 3, achieving reciprocating scraping of the bottom of the compaction block 3 to ensure cleaning effect. When the scraper 7 needs to be replaced, the limiting block 9 is screwed outward to separate the limiting block 9 from the connecting plate 8, and the scraper 7 can be removed and replaced.
[0033] Specifically, the transmission components include a rotating shaft 12, a connecting block 11, a first gear 13, and a second gear 14. An installation groove 16 is provided on the inner side wall of the support column. The rotating shaft 12 is rotatably installed in the installation groove 16. Two first gears 13 are symmetrically arranged vertically and are coaxially arranged, both fixed on the rotating shaft 12. Two connecting blocks 11 are arranged vertically and are coaxially arranged, both fixed on the rotating shaft 12. The second gear 14 is located on the side of the two first gears 13 away from the compaction block 3, and is sequentially meshed with the two first gears 13 at intervals. The second gear 14 is installed at the output end of the drive motor 15. The upper connecting block 11 is hinged to the end of the connecting plate 8 away from the compaction block 3.
[0034] In this embodiment, gear 14 is an irregular bevel gear. The drive motor 15 drives gear 14 to rotate. Gear 14 first drives gear 13 above to rotate, and then drives connecting block 11 to rotate through shaft 12. This causes the cleaning component and electric telescopic rod 10 to rotate horizontally to one side, completing the cleaning of the bottom of compacted block 3. Gear 14 continues to rotate and then meshes with gear 13 below. Gear 13 below drives shaft 12 and connecting block 11 to rotate in the opposite direction, causing the cleaning component and electric telescopic rod 10 to rotate horizontally in the opposite direction to the other side, thereby reciprocating the cleaning of the bottom of compacted block 3.
[0035] Specifically, the lower end of the electric telescopic rod 10 is hinged to the connecting block 11 below, and the upper end of the electric telescopic rod 10 is hinged to the bottom of the connecting plate 8, for rotating the cleaning and scraping parts in the vertical direction.
[0036] In this embodiment, when the compaction block 3 is not in use, the electric telescopic rod 10 drives the cleaning component to rotate vertically, so that it is folded up and avoided damage due to accidental contact.
[0037] In use, the entire device is moved to the outside of the sampling hole to be compacted by the brake wheel 6. The brake component of the brake wheel 6 is stepped on to stop the device in that position. The switch 5 is pressed to connect the power supply device 4, the power vibration device 2, and the cleaning device. At this time, the cleaning component is folded and located in the initial position. The drive motor 15 drives the gear 14 to rotate. The gear 14 meshes with the gear 13 below, causing the cleaning component and the electric telescopic rod 10 to rotate horizontally to the starting position on one side of the support column. The gear 14 separates from the gear 13 below, the drive motor 15 stops operating, and the electric telescopic rod 10 causes the cleaning component to rotate upward until it is parallel to the ground. The electric telescopic rod 10 then stops operating.
[0038] The power vibration device 2 controls the compaction block 3 to move up and down, thereby compacting the backfill material at the sampling hole. After the compaction block 3 moves up, the three cleaning devices operate in sequence. The drive motor 15 continues to operate, causing gear 2 14 to drive gear 1 13 above to rotate. This drives the connecting block 11 to rotate through the rotating shaft 12, thereby causing the cleaning component and the electric telescopic rod 10 to rotate horizontally to one side. When the cleaning component moves to the end position, gear 2 14 separates from gear 1 13 above, completing the cleaning of the bottom of the compaction block 3. Gear 2 14 continues to rotate and then meshes with gear 1 13 below. Gear 1 13 below drives the rotating shaft 12 and the connecting block 11 to rotate in the opposite direction, causing the cleaning component and the electric telescopic rod 10 to rotate horizontally in the opposite direction to the other side, thereby reciprocating the cleaning of the bottom of the compaction block 3. After the cleaning is completed, the cleaning component returns to the starting position, and the compaction block 3 continues to move down for compaction. The operation can be repeated.
[0039] After compaction, the drive motor 15 resets the scraper to its initial position. If the scraper 7 needs to be replaced, the limiting block 9 is screwed outward to separate the limiting block 9 from the connecting plate 8, and the scraper 7 can be removed and replaced.
[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
