Description

Technical Field

[0001] This invention relates to the field of compaction machines, specifically to a foundation compaction device used in building and civil engineering. Background Technology

[0002] Foundation refers to the soil or rock mass that supports the foundation of a building. Foundations are divided into natural foundations and artificial foundations. Natural foundations are natural soil layers that do not require reinforcement, while artificial foundations require reinforcement treatment. Common types include stone chip cushion layers, sand cushion layers, and mixed lime-soil backfilling and compaction.

[0003] With the development of society, various construction industries have emerged. Before pouring concrete on the ground during the construction process, it is necessary to compact the ground to improve the compactness of the subfloor and prevent phenomena such as ground subsidence after the concrete is poured.

[0004] For example, patent document CN217678995U discloses a foundation pouring and compaction device that improves compaction efficiency. It includes a base plate, a push handle, and casters. Multiple sets of casters are provided at the bottom of the base plate, and a push handle is located on the top left side of the base plate. The base plate has an opening. It also includes a guide bar, a compaction head, a top plate, connecting blocks, an electromagnet, connecting plates, a switch button, a lifting mechanism, and a support mechanism. Two sets of guide bars are installed on the top of the base plate, and the tops of both sets of guide bars are connected to the bottom of the top plate. A circular opening is provided on the top plate. The lifting mechanism is installed on the top plate, and the electromagnet is raised and lowered via the lifting mechanism. Connecting plates are symmetrically arranged on the outer wall of the electromagnet, and the two sets of connecting plates are slidably connected to the two sets of connecting blocks. Connecting blocks are symmetrically arranged on the outer wall of the compaction head, and the two sets of connecting blocks are slidably connected to the two sets of guide bars. The electromagnet is directly above the compaction head, and the switch button is located at the bottom of the top plate and is electrically connected to the electromagnet.

[0005] However, the aforementioned patent documents still have the following shortcomings in practical application:

[0006] It is inconvenient to automatically collect and centrally process the garbage on the ground before compaction, which not only pollutes the surrounding environment and is not environmentally friendly, but may also affect the compaction work and reduce the compaction efficiency.

Then, the third electric telescopic rod is started, causing the rectangular block to move. With the cooperation of the fifth and tenth connecting rods, the clamping boxes on the left and right sides move closer together, placing the garbage inside the clamping box. Then, the second electric telescopic rod is started again, causing the first, second, third, and fourth connecting rods to rotate, changing the angle between them again, thus raising the frame.

The first motor 11 drives the threaded rod 13 to rotate, causing the mounting plate 14 to move forward, positioning the clamping box 22 above the garbage. Then, the second electric telescopic rod 35 is started, causing the first connecting rod 16, the second connecting rod 17, the third connecting rod 18, and the fourth connecting rod 19 to rotate, changing the angle between them. This lowers the frame 21, positioning the clamping boxes 22 on both sides of the garbage. Then, the third electric telescopic rod 46 is started, driving the rectangular block 31 to move. With the cooperation of the fifth connecting rod 32 and the tenth connecting rod 44, the clamping boxes 22 on the left and right sides move closer together, placing the garbage inside the clamping boxes 22. Then, the second electric telescopic rod 35 is started again, causing the first connecting rod 16, the second connecting rod 17, the third connecting rod 18, and the fourth connecting rod 19 to rotate, changing the angle between them again, raising the frame 21. Then, the third electric telescopic rod 35 is started. A motor 11 drives the threaded rod 13 to rotate, causing the clamping box 22 to move backward and position itself above the collection box 23. Then, the third electric telescopic rod 46 is activated again, causing the clamping boxes 22 to move away from each other, allowing the garbage to fall into the collection box 23. Then, the second motor 28 is activated, driving the first worm gear 30 to rotate, causing the ninth link 43 and the sixth link 33 to move the displacement plate 24 left and right. Under the action of the rack 42, the second gear 41 rotates, causing the second bevel gear 40 and the first bevel gear 27 to rotate. Under the action of the first gear 26, the cone spike rod 25 rotates, squeezing and crushing the garbage, causing the liquid in the garbage to flow out, thus achieving solid-liquid separation. This can achieve the effect of automatic collection and centralized treatment of garbage on the road surface, thereby avoiding the situation where garbage on the road surface affects the compaction work. Furthermore, it can achieve solid-liquid separation of garbage, making it convenient for personnel to collect and more environmentally friendly.

[0047] In this embodiment, as Figure 1 As shown, universal wheels 8 are provided at the four corners of the lower end face of the base plate 1, and flattening rollers 9 are rotatably connected to the lower left and right ends of the rear side of the base plate 1 through pins.

[0048] When in use, the compacted foundation is further flattened by using the flattening roller 9, thereby improving the compaction effect.

[0049] In this embodiment, as Figure 7 As shown, sleeves 4 are fixedly connected to both the left and right ends of the rear side of the upper end face of the base plate 1, and handles 2 are slidably connected to the sleeves 4; the base plate 1 is also provided with an adjustment component for adjusting the height of the handles 2; the adjustment component includes a lifting plate 3, the left and right ends of the lifting plate 3 are fixedly connected to the handles 2, the middle of the rear end face of the lifting plate 3 is rotatably connected to a seventh link 36 through a pin, the lower end of the seventh link 36 is rotatably connected to an eighth link 37 through a pin, the lower end of the eighth link 37 is fixedly connected to a second worm gear 38 through a pin, and both the eighth link 37 and the second worm gear 38 are rotatably connected to the base plate 1 through pins; the middle of the rear side of the upper end of the base plate 1 is rotatably connected to a second worm 39, and the second worm 39 and the second worm gear 38 mesh with each other;

[0050] In use, the second worm gear 39 is manually rotated to drive the second worm wheel 38 to rotate, which changes the angle between the seventh link 36 and the eighth link 37, allowing the handle 2 to slide inside the sleeve 4. This allows the height of the handle 2 to be adjusted, making it convenient for people of different heights to use, which is quite practical and convenient.

[0051] Working principle of this invention: In use, according to the operator's height, the operator manually rotates the second worm gear 39, which drives the second worm wheel 38 to rotate. This changes the angle between the seventh link 36 and the eighth link 37, allowing the handle 2 to slide inside the sleeve 4. This adjusts the height of the handle 2, making it convenient for users of different heights. It is practical and convenient. Then, using the casters 8, the device is moved to a designated position. When there is trash on the ground, the operator can start the first motor 11. The first motor 11 drives the threaded rod 13 to rotate, causing the mounting plate 14 to move forward, positioning the clamping box 22 around the trash. At the top, the second electric telescopic rod 35 is activated, causing the first connecting rod 16, the second connecting rod 17, the third connecting rod 18, and the fourth connecting rod 19 to rotate, changing the included angle between them. This lowers the frame 21, positioning the clamping boxes 22 on both sides of the waste. Then, the third electric telescopic rod 46 is activated, moving the rectangular block 31. With the cooperation of the fifth connecting rod 32 and the tenth connecting rod 44, the clamping boxes 22 on the left and right sides move closer together, placing the waste inside the clamping boxes 22. Finally, the second electric telescopic rod 35 is activated again, causing the first connecting rod 16, the second connecting rod 17, the third connecting rod 18, and the fourth connecting rod 19 to rotate. The movement changes the angle between the four parts, causing the frame 21 to rise. Then, the first motor 11 is activated, driving the threaded rod 13 to rotate, causing the clamping box 22 to move backward and position itself above the collection box 23. The third electric telescopic rod 46 is then activated again, causing the clamping boxes 22 to move away from each other, allowing the garbage to fall into the collection box 23. The second motor 28 is then activated, driving the first worm gear 30 to rotate, causing the ninth and sixth connecting rods 43 to move the displacement plate 24 left and right. Under the action of the rack 42, the second gear 41 rotates, causing the second bevel gear 40 and the first bevel gear 27 to rotate. The first gear 26 rotates the cone-shaped spike rod 25 to crush and squeeze the garbage, causing the liquid in the garbage to flow out, thus achieving solid-liquid separation. This allows for automatic collection and centralized treatment of garbage on the road surface, preventing garbage from affecting the compaction work. Furthermore, the solid-liquid separation of garbage facilitates collection and is more environmentally friendly. Then, the compaction disc 7 is aligned with the position to be compacted, and the first electric telescopic rod 6 is activated to lower the compaction disc 7 for compaction. The flattening roller 9 is used to further flatten the compacted foundation, thereby improving the compaction effect.
