Description

Technical Field

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

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cement, sand and gravel aggregates and water in a certain proportion, which is evenly mixed, compacted and hardened.

[0003] A uniform feeder for concrete production disclosed in Chinese patent CN218196063U is retrieved. By setting a folding plate, the blocking area can be reduced to a greater extent during use, which can alleviate the blockage to a certain extent. A baffle is added at the pipe mouth to prevent the raw materials from falling into the concrete box before mixing, and reduce the possibility of blockage after mixing is completed.

[0004] However, there are still some problems with a uniform feeder for concrete production. Although this patent can solve the problem of feeder blockage, it cannot measure the weight of the ingredients. When ingredients need to be added, they are generally weighed and then manually poured into the raw material chamber. During the pouring process, the ingredients are easily dropped, resulting in a waste of ingredients. In addition, the labor intensity of the staff is relatively high during the pouring process.
