Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, and in particular to a concrete paver and its method of use. Background Technology

[0002] A concrete paver is a heavy-duty engineering machine used for the continuous and efficient laying, leveling, compacting, and initial smoothing of large areas of concrete pavement. It is mainly used for the construction of highways, airport runways, large parking lots, industrial floors, and other concrete projects that require high precision, high efficiency, and smoothness.

[0003] During common concrete paver operations, as the paver moves, the paving rollers installed on it level the concrete. However, air bubbles can be unintentionally incorporated into the concrete during pouring and paving, forming cavitation. After the concrete is leveled, when the air bubbles are eliminated, the concrete above the cavitation settles, causing depressions on the concrete surface and affecting the smoothness of the paved surface. Workers usually need to use vibrating equipment to vibrate and remove the air bubbles behind the paver as it moves, increasing the labor intensity of the workers, making it difficult to remove cavitation, and increasing construction costs.

The rotating disk 416 rotates together; the second bevel gear 410 is fixedly connected to the rotating rod 49, and the second bevel gear 410 meshes with the first bevel gear 48. The meshing action of the second bevel gear 410 and the first bevel gear 48 causes the first bevel gear 48 to drive the mounting block 43 and the movable rod 41 to rotate; the fixed disk 411 is fixedly connected to the top of the movable rod 41, and the fixed disk 411 is located below the connecting block 45. The fixed disk 411 rotates together with the movable rod 41, and drives the movable rod 41 to move vertically.Movable blocks 412 are disposed on both sides of the fixed disk 411. The bottom of the movable blocks 412 is square-shaped and slides through the bottom of the mounting bracket 2. The movable blocks 412 are convex in shape. The two movable blocks 412 are disposed on both sides of the fixed disk 411 to drive the fixed disk 411 to move vertically. The bottom of the movable blocks 412 slides through the mounting bracket 2 to prevent the movable blocks 412 from rotating. A connecting groove 413 is formed on one side of the top of the movable blocks 412 and slides through one side of the fixed disk 411. The connecting groove 413 is used to install and accommodate the edge of the fixed disk 411. When the mounting block 43 drives the movable rod 41 to rotate, the fixed plate 411 rotates together with the movable rod 41, and the fixed plate 411 rotates within the connecting groove 413 of the two movable blocks 412; the compression spring 414 is movably sleeved with the bottom of the movable block 412, and the bottom end of the compression spring 414 is in contact with the bottom of the inner wall of the mounting bracket 2.

The groove 418 has one side vertically oriented and the other side inclined, which facilitates the pressing and pushing of the fixed column 415, allowing the fixed column 415 to enter the movable groove 417 from the groove 418.

10. A method of using a concrete paver, characterized in that, Using a concrete paver as described in any one of claims 1-9 includes the following steps: Step S1: Use the rollers installed at the bottom of the frame (1) to push the frame (1) to move along the set track. Through the operation of the drive motor (36), the second pulley (37) and the first pulley (35) will rotate together. The mounting rod (31) and the mixing block (33) will rotate together with the first pulley (35). The mixing block (33) will rotate into the concrete to mix the concrete and prevent the concrete from solidifying. Step S2: As the drive motor (36) runs, it drives the rotating rod (49) to rotate. Multiple second bevel gears (410) rotate together with the rotating rod (49). By utilizing the meshing action of the second bevel gears (410) and the first bevel gear (48), the first bevel gear (48) and the mounting block (43) rotate together. The mounting block (43) drives the connecting block (45), the movable rod (41), and the auger (42) to rotate. Step S3: The rotating rod (49) drives multiple rotating disks (416) to rotate together. The inner wall of the movable groove (417) on the rotating disk (416) squeezes and pushes the fixed column (415), and the fixed column (415) slides in the movable groove (417), pushing the fixed column (415) and the movable block (412) to move vertically downward. The movable block (412) drives the fixed disk (411), the movable rod (41), and the auger (42) to move vertically downward. The connecting block (45) slides in the installation groove (44), so that the auger (42) enters the concrete downward. At the same time, as the auger (42) rotates, the spiral blades on the auger (42) push the concrete. Step S4: As the rotating disk (416) rotates, it drives the extrusion block (420) to rotate to the protrusion (419) at the top of the movable block (412), and squeezes the protrusion (419), pushing the movable block (412) to slide into the groove (418). The movable block (412) drives the fixed disk (411) and the auger (42) to move, compressing the compression spring (414). Using the elastic effect of the compression spring (414), it pushes the movable block (412) and the auger (42) to rebound, thereby driving the auger (42) to vibrate, driving the concrete to vibrate, and performing defoaming treatment on the concrete. Step S5: After the concrete has been processed by steps S1, S3 and S4, the servo motor (54) drives the third pulley (53) and the fourth pulley (55) to rotate. The paving roller (52) rotates together with the third pulley (53). As the frame (1) moves, the paving roller (52) squeezes and pushes the concrete surface to flatten the concrete.
