[0018] Specifically, a feed port 10 is provided at the upper end of the machine body 1, and a feed hopper 11 is provided at the upper end of the feed port 10. The setting of the feed port 10 and the feed hopper 11 is convenient for the staff to add the coated sand raw material into the mixing chamber 2. The diameter of the feed hopper 11 is larger than the diameter of the feed port 10, which prevents the staff from scattering the coated sand to the outside of the feed port 10 during work, thereby speeding up the work efficiency.

[0019] Specifically, a bracket 12 is provided at the upper end of the body 1. The bracket 12 is composed of a transverse plate and a longitudinal plate. The transverse plate is fixed to the upper end of the longitudinal plate. Reinforcing ribs are provided at the connection between the transverse plate and the longitudinal plate. A driving assembly 6 is provided on the transverse plate.

[0021] Specifically, the driving assembly 6 includes a stirring motor 6-1 and a coupling 6-2. The stirring motor 6-1 is arranged on the upper side of the machine body 1. The coupling 6-2 is used to connect the driving end of the stirring motor 6-1 and the stirring rod 5. The coupling 6-2 refers to a device that connects two shafts or a shaft and a rotating part, rotates together during the process of transmitting motion and power, and does not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads, thereby playing a role in overload protection.

[0023] Working principle: When the utility model is working, sand is added into the stirring chamber 2 through the set feed port 10 and the feed hopper 11, and the stirring motor 6-1 is started. The stirring rod 5 connected thereto stirs and separates the coated sand to prevent the coated sand from agglomerating and affecting the screening of the coated sand. The sand dispersed after filtering, screening and stirring is filtered through the set screen 4, and the driving motor 16 is started to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the tamping rod 8 to rotate, and the rubber tamping ball 9 on the rotating tamping rod 8 hits the screen 4 to vibrate the screen 4 to prevent the screen 4 from being blocked, thereby accelerating the screening efficiency of the screen 4 for the coated sand.
