Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete mixers, and more particularly to a wear-resistant concrete pouring device. BACKGROUND

[0002] In the existing construction, concrete is an important construction material. When making concrete, cement sand and water and other materials need to be mixed according to a certain proportion. At this time, a concrete mixer needs to be used. In the existing wear-resistant forced single-horizontal-shaft concrete mixer, the stirring rod in the stirring shell is a fixed structure. For different concentrations of concrete mixing liquid, the fixed stirring rod produces a stirring radius that can easily increase the stirring load or reduce the stirring efficiency. For example, when high-concentration concrete mixing liquid is needed, the stirring radius of the stirring rod is large, which can easily increase the stirring load and thus accelerate the wear of the stirring rod. Therefore, a small stirring radius is needed. However, when the stirring radius is small, the stirring efficiency is low when stirring low-concentration concrete liquid. Moreover, it is inconvenient to clean after use.

[0003] The existing technology with the publication number CN211492195U provides a wear-resistant forced single-horizontal-shaft concrete mixing device. The device is provided with a rotating shaft, a sliding sleeve, a connecting plate, and a stirring plate on the stirring part. The sliding sleeve is axially slidingly fitted on the rotating shaft. The sliding sleeve is hingedly connected through the connecting plate and the stirring plate. The number of stirring plates is two and is symmetrically distributed relative to the rotating shaft axis. The radial position of the stirring plate in the stirring shell can be adjusted by sliding the sliding sleeve, and thus the stirring radius can be changed, which is suitable for stirring different concentrations of concrete liquid.

[0004] The existing technical solution in the above can achieve the beneficial effects related to the existing technology. However, it still has the following defects: When adjusting the stirring radius of the stirring plate, the device needs to be operated from the inside of the stirring barrel, which can cause inconvenience in operation. At the same time, a large amount of cement can adhere to the hands during operation, which is inconvenient to clean.

[0005] In view of this, we propose a wear-resistant concrete pouring device. CONTENT OF THE UTILITY MODEL
