Technical Field

[0001] This utility model relates to the field of cement paving machinery technology, specifically a cement leveling device. Background Technology

[0002] With the development of concrete pavement, the research and production of road cement has received increasing attention. my country has formulated standards for road silicate cement. Compared with silicate cement clinker, road cement clinker contains less aluminate phase and more ferroaluminate phase. In addition to having better wear resistance, drying shrinkage resistance and sulfate resistance, road cement also has higher early strength. Road cement is based on the original silicate cement series. Through the adjustment of mineral composition and reasonable calcination and grinding, road cement has characteristics superior to the corresponding silicate cement.

[0003] Chinese patent document CN221460869U discloses a cement spreading device for road construction, belonging to the field of cement mixing and spreading technology.

This cement spreading device, through the configuration of a first motor, a first conical tooth, a first threaded rod, a threaded cap, a connecting rod, and a scraper, allows for adjustment of the cement spreading thickness. A control switch controls the first motor, which in turn rotates the first and second conical teeth, the first and second threaded rods, and simultaneously rotates the threaded cap and connecting rod. This, in turn, moves the fixed platform and scraper up and down to a specified height, facilitating the adjustment of the cement spreading thickness. The combined action of the first motor, first conical tooth, first threaded rod, threaded cap, connecting rod, and scraper makes it easier to adjust the cement spreading thickness.

The drive motor 11 is used to drive and control the leveling roller 5 and the fine leveling roller 12 to perform synchronous operation. The leveling roller 5 is used to perform initial leveling operation on the cement ground, and the fine leveling roller 12 is used to perform further fine leveling operation on the cement ground.

[0021] Furthermore, the output end of the drive motor 11 is connected to the drive wheel 10 via a rotating shaft. The surface of the drive wheel 10 is connected to the driven wheel 8 via a belt 9. The center of the surface of the driven wheel 8 is connected to the first sprocket 14 via a rotating shaft. The surface of the first sprocket 14 is connected to the second sprocket 13 via a chain 15. The center of the surface of the second sprocket 13 is connected to the precision leveling roller shaft 12 via a rotating shaft. By turning on the drive motor 11, the drive wheel 10 is driven to rotate, thereby driving the driven wheel 8 to rotate. Then, the first sprocket 14 drives the second sprocket 13 to rotate, thereby driving and controlling the precision leveling roller shaft 12 to operate.

[0022] Furthermore, the surface of the driven wheel 8 is connected to the first rotating wheel 7 via the belt 9. The center of the surface of the first rotating wheel 7 is connected to the second rotating wheel 16 via the rotating shaft. The surface of the second rotating wheel 16 is connected to the third rotating wheel 18 via the transmission belt 17. The center of the surface of the third rotating wheel 18 is connected to the flattening roller shaft 5 via the rotating shaft. The rotation of the first rotating wheel 7 drives and controls the second rotating wheel 16 to drive the third rotating wheel 18 to rotate, thereby driving and controlling the flattening roller shaft 5 to perform operation.

[0023] Furthermore, a fixed push rod 2 is welded to one end of the flattening cart 4, and a push handle 1 is provided on the fixed push rod 2, so that the operator can hold the push handle 1 to move the flattening cart 4 flexibly. The bottom of the flattening cart 4 is equipped with moving wheels 6, and the upper surface of the flattening cart 4 is equipped with a power control box 3. The power control box 3 is connected to the drive motor 11 through wires and can provide power to the drive motor 11.

[0024] Working principle: When paving a cement road surface, the operator holds the handle 1 to push the paving cart 4. The paving cart 4 is equipped with a drive motor 11. By turning on the drive motor 11, the driving control wheel 10 is driven to rotate, which in turn drives the driven wheel 8. The first sprocket 14 drives the second sprocket 13 to rotate, thereby driving the fine leveling roller 12 to operate. The surface of the driven wheel 8 is connected to the first rotating wheel 7 via a belt 9. The center of the surface of the first rotating wheel 7 is connected to the second rotating wheel 16 via a shaft. The surface of the second rotating wheel 16 is connected to the third rotating wheel 18 via a transmission belt 17. The surface of the third rotating wheel 18... The center of the surface is connected to the leveling roller 5 via a rotating shaft. The rotation of the first rotating wheel 7 drives the second rotating wheel 16 to drive the third rotating wheel 18 to rotate, which in turn drives the leveling roller 5 to operate. This allows the leveling roller 5 and the fine leveling roller 12 to operate synchronously. The leveling roller 5, located at the front of the leveling trolley 4, performs initial leveling on the cement surface, while the fine leveling roller 12, located at the rear of the leveling trolley 4, performs further fine leveling on the cement surface. This effectively ensures the flatness of the cement pavement during paving operations and improves the forming quality and effect of the cement pavement. The entire device is compact, convenient, and highly flexible.
