Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated locking brick production, in particular to a raw material mixing device for the production of prefabricated locking bricks. Background Art

[0002] Cement prefabricated locking bricks are a common building material. Its production raw materials mainly include cement, sand, gravel and water. These raw materials need to be mixed in a certain proportion to produce prefabricated locking bricks with certain strength and stability.

[0003] After searching, the patent with application number 202222661992.5 discloses a raw material mixing device for prefabricated brick production, which includes a mixing box and a stirring and cleaning component. A material discharge component is arranged on the top of the mixing box. The patent can add three mixed amounts at a time, which is convenient for continuous material discharge and reduces the workload of the staff for material feeding. However, the patent will have the following problems in the actual operation process:

[0004] First, the agitator paddle used is relatively large in size, which occupies a relatively large raw material mixing space in the mixing box. This not only results in a poor mixing effect between the raw materials, but also a large amount of raw materials are easily attached to the surface of the agitator paddle and cannot be discharged normally, thereby reducing the subsequent discharge volume.

[0005] Secondly, the bottom of the mixing box does not have a height adjustment component, so the height of the mixing box cannot be flexibly adjusted during use, which makes it inconvenient to inspect or clear the discharge pipe area at the bottom of the mixing box. Utility Model Content
