Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a high-efficiency feeding mechanism for concrete production. Background Technique

[0002] Concrete is one of the most important civil engineering materials in modern times. It is a kind of artificial stone prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added as necessary in a certain proportion, uniformly stirred, densely formed, and cured and hardened. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its application range very wide. It is not only used in various civil engineering projects, but also in the shipbuilding industry, mechanical industry, ocean development, geothermal engineering, etc. Concrete is also an important material.

[0003] In the Chinese patent with the publication number CN220446801U, a feeding mechanism for concrete production is disclosed. It places the feeding mechanism on one side of the mixing tank, rotates the rotating plate so that the hook is located in the inner cavity of the mixing tank, then rotates the threaded rod, and drives the hook to move by the threaded rod so that the hook hangs on the top of the mixing tank, thus completing the installation. The operation is convenient, and at the same time, the height of the device can be adjusted by using a multi-section telescopic rod, so as to be applicable to mixing tanks of different heights and sizes.

[0004] In the above solution, the feeding tank is flipped by the cooperation of structures such as the second motor and the support rod to complete the feeding of the mixing tank. However, when feeding in a dumping manner, the raw materials are likely to remain in the feeding tank, resulting in an imbalance in the ratio of the raw materials. Moreover, the raw materials will accumulate and caking in the feeding tank, and the caked raw materials are not easy to mix with other raw materials when directly put into the mixing tank, affecting the quality of the concrete. Therefore, we provide a high-efficiency feeding mechanism for concrete production to solve the above problems. Content of the Utility Model
