Description

Technical Field

[0001] The present invention relates to the technical field of concrete construction, and in particular to a green and low-carbon concrete construction device. Background Art

[0002] The term concrete refers to cement as a binder, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a certain proportion and then stirred to form cement concrete, also known as ordinary concrete. It is widely used in civil engineering. Currently, the construction industry usually mixes cement, water, stone and additives during concrete construction, and then stirs them to make concrete.

[0003] During the existing green concrete pouring process, its surface needs to be smoothed, and smoothing requires the use of corresponding construction tools. The traditional concrete laying method is that workers pour concrete on the road surface to be paved and smooth the concrete with a scraper. Due to the relatively single functionality of the construction tools, when the road surface is not flat, the concrete laid in this way may be uneven, requiring secondary leveling by personnel, which is labor-intensive and inefficient.

When the half gear 27 and the rack 25 are separated, the spring 24 and the pressing cylinder 21 fall rapidly under the action of the pressure. The rapid rotation of the half gear 27 drives the pressing cylinder 21 to move up and down in a small range. The pressing cylinder 21 rotates and moves up and down while it is on the concrete to flatten the concrete surface.

By rotating the threaded rod 232, the angle between the wiping plate 29, the leveling plate 30 and the concrete surface can be adjusted, which is convenient for leveling the concrete surface.

[0035] When the device is working, stones are put into the feed hopper 4, and the motor 11 is started to drive the crushing roller 5 and the rotating roller 8 to rotate. The crushing roller 5 crushes the stones, and the crushed stones fall on the upper end of the inclined plate 7.
