Description

Technical Field

[0001] The utility model relates to the technical field of mortar filling and blanking, in particular to a special blanking rack for dry powder mortar filling. Background Art

[0002] Dry-mix mortar refers to a granular or powdery material made by physically mixing dried and sieved aggregates, inorganic cementitious materials and additives in a certain proportion. It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. Dry-mix mortar plays a bonding, cushioning, protective and decorative role in the construction industry in a thin layer, and is widely used in construction and decoration projects.

[0003] Existing mortar filling and blanking technology often adopts a dry mortar blanking device such as the one disclosed in the announcement number CN213504977U, which drives the first screw to rotate by a first motor, thereby driving the slide plate and the sliding mechanism to slide back and forth as a whole; at the same time, the second motor of the sliding mechanism drives the second screw to rotate, and the second screw drives the slide to slide to the inlet of the tank body, so that the lower end of the blanking pipe is inserted into the inlet, thereby avoiding the driver from frequently correcting the vehicle position and dragging the blanking pipe. However, dry mortar is a viscous substance. During the blanking process, the falling speed is slow and the blanking pipe is blocked. Personnel are required to clear the blanking pipe, which leads to low work efficiency. Utility Model Content
