Description

Technical Field

[0001] The present application relates to the field of mixing ratio control equipment, and in particular to a blanking device for a mixing ratio control equipment. Background Art

[0002] Dry-mixed mortar refers to a granular or powdery material obtained by physically mixing dried and screened aggregates (such as quartz sand), inorganic binders (such as cement), and additives (such as polymers) in a certain proportion, and transported to the construction site in bags or bulk form. After adding water and mixing, it can be directly used.

[0003] When dry-mixed mortar is mixed, it needs to be mixed according to a certain mixing ratio, which requires the use of corresponding mixing ratio control equipment. The mixing ratio control equipment generally includes a temporary storage tank, a blanking pipe is arranged below the storage tank, and a blanking roller driven by a motor is arranged below the blanking pipe. Generally, four installation slots are arranged along the circumference of the blanking roller, and weighing sensors are arranged in the installation slots. The material in the blanking pipe enters the installation slots. After being weighed by the weighing sensors and reaching the specified amount, the motor drives the blanking roller to rotate, so that the next empty installation slot rotates below the blanking pipe, and the material in the lowermost installation slot will be poured into the bag.

[0004] However, the inventor believes that during the whole process, when the material in the blanking pipe enters the installation slots, since the material is powdery, a large amount of dust will inevitably occur during the falling process, and the same problem also exists when pouring out from the installation slots. Therefore, the inventor believes that it needs to be improved. Utility Model Content
