[0002] Concrete batching machine, also known as batching machine or automatic sand and gravel batching machine, is an automated equipment used for quantitative distribution of various materials such as sand and gravel. It is mainly used in the concrete construction industry to replace manual scales or volume measurement. Therefore, the existing concrete also needs to use corresponding batching machines for weighing ingredients during the mixing and manufacturing process.

[0003] Announcement No. "CN215920922U" provides a concrete batching machine, which is equipped with multiple storage hoppers for convenient material storage. A vibrating screen is installed inside the storage hopper, and a discharge pipe is connected to the end to facilitate the screening of raw materials with excessively large particles and collection for further processing.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the concrete batching machine can prevent dust from being raised when the raw materials fall by means of the dust cover and dust cloth, there is a certain gap between the dust cover and dust cloth and the storage hopper and the receiving hopper. Therefore, during actual use, some dust still escapes to the outside through the gap, and the dust prevention effect is poor. Secondly, the dust cover and dust cloth are not provided with corresponding disassembly and assembly structures for disassembly and assembly, which makes it difficult to replace the dust cover and dust cloth when needed later, and the disassembly and assembly is not convenient.
