Description

Technical Field

[0001] The utility model belongs to the technical field of concrete paving, and specifically relates to a concrete leveling mechanism. Background Art

[0002] Concrete is an artificial building material composed of cement, sand, aggregates (such as gravel or crushed stone) and water in a certain proportion. Due to its strong and durable characteristics, concrete is widely used in the load-bearing parts of building structures, such as foundations, columns, beams, etc. Concrete has good fire resistance at high temperatures and is suitable for various fire protection requirements. It is mainly used in the construction of various structures and foundations, such as houses, bridges, roads, dams, etc. Paving concrete refers to spreading concrete evenly on the required surface through specific mechanical equipment during the building construction process. A concrete paver can ensure that the concrete is evenly distributed and leveled at the construction site, avoiding unevenness or uneven density. Generally speaking, paving concrete is a key process step in modern building construction, which not only improves the engineering efficiency and quality, but also ensures the long-term stability and safety of the building structure.

[0003] Due to the high viscosity of concrete, it is easy to accumulate at the bottom and around the paving mechanism, resulting in wear and deformation of the paving mechanism. Summary of the Utility Model

[0004] In view of this, the utility model provides a concrete leveling mechanism, aiming to solve the problem that due to the high viscosity of concrete, it is easy to accumulate at the bottom and around the paving mechanism, resulting in wear and deformation of the paving mechanism.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a concrete leveling mechanism, which includes a paving blade, a wear-resistant scraping block, a paving disc, a feeding port and a connecting part nut; the wear-resistant scraping block is installed on the inner arc surface of the paving blade, the surface shape of the wear-resistant scraping block in contact with the paving blade is adapted to the shape of the inner arc surface of the paving blade, and the upper and lower edges of the wear-resistant scraping block are 6-10 millimeters higher than the edge of the paving blade; the paving disc is arranged below the concrete feeding tank.

[0007] The technical effects of a concrete paving mechanism provided by the present utility model are as follows: By setting the upper and lower sides of the wear-resistant scraping block to be 6-10 mm higher than the edges of the paving blade, a certain gap is generated between the lower part of the paving blade and the concrete material, reducing the frictional resistance between the surface of the paving blade and the material during operation; and when there is a relatively large amount of concrete during the operation of the paving blade, it will cover the paving blade, and in this way, the surface of the paving blade also bears the weight of the material, preventing the paving blade from being lifted upward due to the hardening of the concrete accumulation at the bottom, which may cause the paving blade to be easily deformed or even lead to the problem of the fracture of the connecting part nut.

[0008] On the basis of the above technical solution, a concrete paving mechanism of the present utility model can be further improved as follows:

[0009] Among them, a plurality of protrusions are provided on the lower side wall of the paving blade.

[0010] The beneficial effects of adopting the above improvement scheme are: By setting a plurality of protrusions on the lower side wall of the paving blade, it can effectively prevent the excessive accumulation of concrete at the bottom and around the paving blade. The protrusions can break the accumulation and help the concrete to be more evenly distributed and paved. The design of the protrusions can reduce the frictional force when the paving blade contacts the concrete, thereby reducing the wear of the paving mechanism. The design of the protrusions can help to better disperse the concrete, ensuring a more uniform and smooth paving effect during the paving process. They can provide a better guiding effect when the concrete is paved, contributing to ensuring the final paving quality.

[0011] Further, the wear-resistant scraping block is made of 16Mn material, and the wear-resistant scraping block is welded to the paving blade in a welding form.

[0012] The beneficial effects of adopting the above improvement scheme are: By setting the wear-resistant scraping block to be made of 16Mn material, the material hardness of the wear-resistant scraping block can be improved.

[0013] Further, the inner arc surface of the paving blade is located at the longitudinal middle position of the contact surface of the wear-resistant scraping block.

[0014] Further, four screw holes are drilled at one end of the paving blade, and the four screw holes are matched with the connecting part nuts at the bottom of the paving disc. The paving blade is installed at the bottom of the paving disc by tightening the screw holes with the connecting part nuts.

[0015] Further, the connecting part nuts are located at the material discharging port at the bottom of the paving disc.

[0016] Further, the height of the paving blade is 36-40 mm; the height of the wear-resistant scraping block is 52-56 mm, and the width is 6-10 mm.

[0017] Further, a plurality of spreading blades are provided.

[0018] Further, the diameter of the material discharge port is 10 cm.

[0019] Further, the length of the spreading blade is less than the diameter of the spreading disc.

[0020] Compared with the prior art, the beneficial effects of a concrete paving mechanism provided by the present utility model are as follows: by setting the upper and lower sides of the wear-resistant scraping block to be 6-10 mm higher than the edge of the spreading blade, a certain gap is generated between the lower part of the spreading blade and the concrete material, reducing the frictional resistance between the surface of the spreading blade and the material during operation; and during the operation of the spreading blade, there is a large amount of concrete, which will cover the spreading blade. In this way, the surface of the spreading blade also bears the weight of the material, preventing the spreading blade from being lifted upward due to the hardening of the concrete accumulation at the bottom, which may cause the spreading blade to be easily deformed or even cause the problem of the nut of the connecting component being broken. By setting a plurality of protrusions on the lower side wall of the spreading blade, it can effectively prevent the excessive accumulation of concrete at the bottom and around the spreading blade. The protrusions can break the accumulation, helping the concrete to be more evenly distributed and paved. The design of the protrusions can reduce the frictional force when the spreading blade contacts the concrete, thereby reducing the wear of the paving mechanism. The design of the protrusions can help to better disperse the concrete, ensuring a more uniform and smooth paving effect during the paving process. They can provide a better guiding effect when the concrete is paved, contributing to ensuring the final paving quality. By setting the wear-resistant scraping block to be made of 16Mn material, the material hardness of the wear-resistant scraping block can be improved. By setting the spreading disc, it supports and guides the movement of the spreading blade, ensuring that the spreading blade maintains a stable position and direction during operation, thereby effectively paving the concrete. It can solve the problem that due to the large viscosity of the concrete, it is easy to accumulate at the bottom and around the paving mechanism, resulting in the wear and deformation of the paving mechanism.
