Afterwards, the lid can be placed on the material bucket, the stirring shaft can be inserted into the material bucket, and the stirring motor drives the blades to rotate, which can stir the material in the material bucket. The feature is that a vertically arranged pneumatic plunger pump is fixed on the lid, which can suck up the material in the material bucket. An air inlet is also opened on the lid, and an air inlet pipe is connected to the air inlet. When sucking up the material, air can be added to the material bucket through the air inlet pipe. A collection box is also provided. A mounting plate is fixed on the rear part of the opening of the collection box, and the base is fixed on the mounting plate. The lid, stirring shaft, and pneumatic plunger pump are all located above the opening of the collection box.

[0009] Furthermore, in the aforementioned mixing and feeding device, a large discharge port is provided on the discharge grid directly below the blades. The area of ​​the large discharge port is larger than the lower projection area of ​​the blades, so that the material on the blades can fall directly into the collection box.

[0010] Furthermore, in the aforementioned mixing and feeding device, a small discharge port is provided on the discharge grid directly below the pneumatic plunger pump. The area of ​​the small discharge port is larger than the lower projected area of ​​the bottom of the pneumatic plunger pump, so that the material on the pneumatic plunger pump can fall directly into the collection box.

[0011] The advantages of this utility model are as follows: the lifting cylinder retracts to lower the lid, which seals the material barrel. The stirring shaft can be inserted into the material barrel, and the stirring motor drives the blades to rotate, stirring the material in the barrel. At the same time, the pneumatic plunger pump can suck the material from the barrel.
