Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and in particular to a concrete pouring device. Background Technology

[0002] Ordinary concrete refers to artificial stone made by mixing cement as the main binder with water, sand, and gravel, and, when necessary, chemical admixtures and mineral admixtures in appropriate proportions, and then uniformly mixing, compacting, molding, and curing. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, i.e., fresh concrete or concrete mixture, and the hard state after hardening, i.e., hardened concrete or concrete.

[0003] A search revealed Chinese Patent Publication No. CN221297509U, which discloses a concrete pouring device with adjustable pouring speed. The device includes a main body, an auxiliary body, and a leveling body. The auxiliary body is located at the left end of the main body, and the leveling body is located at the lower end of the auxiliary body. The main body includes a mixing tank, a drive motor, a feed inlet, and a cover plate. The adjustable pouring speed concrete pouring device, through the installation of the main body, achieves the following: a rotating rod fixes a mixing rod, which mixes the concrete evenly; a fixed scraper scrapes the concrete off the inner wall of the mixing tank as the mixing rod rotates, preventing concrete from adhering to the inner wall; a bearing fixing bracket ensures stable rotation of the rotating rod; a valve closes the discharge port to prevent concrete from flowing out during mixing; and a pulling device moves the valve to allow the mixed concrete to flow out, improving the cleanliness of the adjustable pouring speed concrete pouring device.

[0004] While the above solution has the advantage of preventing concrete from adhering to the inner wall of the mixing tank, in actual use, the concrete adhering to the scraper surface cannot be cleaned, and the cleaning effect of cleaning the inner wall of the mixing tank by scraping alone is poor.

[0005] Therefore, there is an urgent need to provide a concrete pouring device to solve the above problems. Utility Model Content
