Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a concrete paver. Background Art

[0002] Concrete is a general term for engineering composite materials that are made by bonding aggregates into a whole with cementitious materials. Cement concrete obtained by mixing concrete and water in a certain proportion is also called ordinary concrete. A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. When concrete is laid on the road surface, it needs to be evenly spread according to a certain thickness, and a paver is needed for this purpose.

[0003] At present, traditional pavers still have some shortcomings. After the paver spreads the concrete, a large amount of concrete will be attached to the paving roller. For this reason, a scraper needs to be installed on the paver to scrape the concrete on the paving rod or the concrete on the paving rod needs to be washed by a manual handheld spray gun after the end. This method not only has a poor effect on concrete cleaning, but also increases the labor burden of the staff. For this reason, we propose a concrete paver. Utility Model Content
