Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete leveling, and in particular to a concrete leveling machine. Background Technology
[0002] Common leveling methods include manual leveling, mechanical leveling, and chemical leveling. Manual leveling is suitable for leveling small areas of concrete and is mainly done manually using scrapers and trowels. Mechanical leveling is suitable for leveling large areas of concrete and is mainly done using mechanical equipment. Chemical leveling uses chemicals to treat the concrete surface to achieve a smooth finish.
[0003] A concrete screed is an engineering machine used to level concrete surfaces to achieve the required flatness. Common pavers are mainly used for large-area concrete leveling. They employ a frame structure, are equipped with double steel wheels or crawler tracks, and have a paving beam at the front. They can automatically adjust the concrete thickness and width for efficient leveling. However, these screeds suffer from low construction efficiency and complex operation. Vibratory screeds rely on vibration to achieve leveling. They are suitable for small to medium-sized concrete surface construction and mainly consist of unidirectional or bidirectional vibrators mounted on a base plate. The vibration frequency is generally 3000-6000 times per minute, effectively eliminating air pores and obtaining a dense, smooth concrete surface. However, these screeds suffer from insufficient leveling precision. Utility Model Content

The arc-shaped rake can be removed from the machine frame 4 through the connecting clips 2.3, facilitating the replacement of the arc-shaped rake 2. Preferably, the plurality of rake teeth 2.2 are evenly distributed on the arc-shaped plate 2.1. When the concrete leveling machine 1 moves forward, the rake teeth 2.2 loosen and even out the concrete, facilitating subsequent leveling of the concrete.
[0028] Specifically, in one embodiment, the leveling assembly 3 mainly includes a fan blade 3.1 and a rotating shaft 3.2. The rotating shaft 3.2 is mounted on the machine frame 4, and the fan blade 3.1 is connected to the rotating shaft 3.2.

The telescopic plate 4.10 is controlled by a switch 4.11, and the telescopic plate 4.10 is electrically connected to the switch 4.11. Preferably, the switch 4.11 is located on the right side of the handrail 4.4. After the film is laid, the switch 4.11 is activated, and the sawtooth 4.7 is pushed out by the telescopic plate 4.10, separating the film from the film roll of the film laying assembly 6, thus completing the film laying of a section of the concrete surface.
[0030] Specifically, in one embodiment, the handrail 4.4 includes two arc-shaped connecting seats 4.4.1, a vertical rod 4.4.2 disposed on the arc-shaped connecting seats 4.4.1, and a horizontal rod 4.4.3 connecting the two vertical rods 4.4.2.

[0032] Specifically, in one embodiment, the film-laying assembly 6 mainly includes a film roll 6.1, a film roll shaft 6.2, film roll baffles 6.3, and fixing rods 6.4.

A connecting belt 5.6 is connected to the two ends of the shaft 6.2 extending out of the film roll 6.1, and the connecting belt 5.6 connects the roller 5.1 and the film roll 6.1 for power transmission. When the inner shaft 5.2 of the roller 5.1 rotates, it can drive the film roll 6.1 to rotate, so that the film can cover the concrete surface leveled by the roller 5.1 with a thin film, preventing the concrete from cracking due to excessive moisture evaporation. The membrane-laying component 6 can level the concrete while simultaneously applying the membrane, without damaging the already leveled cement surface, eliminating the need for secondary leveling and reducing workload.
[0033] Specifically, in one embodiment, the driving assembly mainly includes a leveling assembly driving power supply 7.1 and a roller assembly driving power supply 7.2. The leveling assembly driving power supply 7.1 provides driving power to the leveling assembly 3, driving the rotating shaft 3.2 to rotate. Preferably, the first power switch 4.12 controlling the start and stop of the leveling assembly driving power supply 7.1 is located on the handrail 4.4. Preferably, the second power switch 4.13 controlling the start and stop of the roller assembly driving power supply 7.2 is located on the handrail 4.4. The roller assembly driving power supply 7.2 provides driving power to the roller assembly 5, causing the roller assembly 5 to move forward and driving the film laying assembly 6 to move forward, thereby driving the entire machine to move forward.
[0034] When using the concrete leveling machine 1, cement, sand, gravel, water and other materials are put into the mixer in a certain proportion and mixed thoroughly to ensure that the materials are uniform. The mixed concrete is transported to the construction site by truck and poured into the construction area. After the concrete is slightly leveled, it is vibrated with a vibrator. The concrete leveling machine 1 is placed on the concrete surface, and the operator stands on the platform 4.5 of the machine frame 4 and holds the crossbar 4.4.3 of the handrail 4.4.
[0035] Turn on the first power switch 4.12 and the second power switch 4.13 of the power supply for the leveling assembly drive power supply 7.1 and the roller assembly drive power supply 7.2, causing the rotating shaft 3.2 of the leveling assembly 3 to start rotating within a certain angle range (e.g., 45°), simultaneously driving the fan blades 3.1 to rotate around the rotating shaft 3.2 on the concrete surface, similar to a windshield wiper. At the same time, the roller assembly drive power supply 7.2 provides drive power to the roller assembly 5, causing the roller assembly 5 to move forward and drive the film laying assembly 6 forward, thereby driving the entire machine forward.
[0036] As the roller assembly 5 moves forward, the rake teeth 2.2 of the arc-shaped rake 2 evenly distribute the concrete, which is then evenly distributed a second time by the leveling assembly 3, and finally leveled by the roller assembly 5.
[0037] The inner shaft 5.2 of the roller assembly 5 rotates, driving the connecting belt 5.6 to rotate the shaft 6.2 of the film-laying assembly 6, which in turn rotates the film roll 6.1, allowing the film on the film roll 6.1 to be laid on the leveled concrete. The switch 4.11 on the machine frame 4 is then turned on, causing the telescopic plate 4.10 to extend outwards, and the serrations 4.7 on the tail ramp 4.6 to extend, cutting the film and completing the leveling work for one area. When the film on the film roll 6.1 is used up, the tail ramp 4.6 is lifted to replace it with a new film.
[0038] The above are merely preferred embodiments of this utility model, and the protection scope of this utility model is not limited to the above embodiments.
