The model of the water level detector 13 is set to be a Cybis industrial induction water level alarm.

[0033] Principle and process of this utility model:

[0034] When using the device, the paint to be stirred must first be poured into the stirring barrel 51 from the leak at the top of the top cover 54, and then the microcomputer sends a signal to control the motors of the first stirring wheel 52 and the second stirring wheel 53 to rotate, and the paint is stirred as the first stirring wheel 52 and the second stirring wheel 53 rotate.

[0035] When the paint is stirred, the microcomputer controls the telescopic end of the electric push rod 7 to retract, thereby pulling the opening and closing plate 8 out of the groove of the connecting hole 6. As the opening and closing plate 8 is pulled out, the stirring barrel 51 and the material storage chamber 3 are connected, and the paint flows into the connecting hole 6 through the discharge port 55, and then sprayed onto the surface of the drain groove 42 through the guide pipe 9;

[0036] At the same time, the microcomputer controls the servo motor 14 to start, and the servo motor 14 rotates to drive the first gear rod 44 to rotate counterclockwise. As the first gear rod 44 rotates, the second gear rod 45 and the first gear belt 41 are driven to rotate. The first gear belt 41 rotates counterclockwise to drive the screen 43 to move synchronously, thereby contacting the paint left on the surface of the drain groove 42, thereby screening impurities in the paint. The screened paint passes through the screen 43 and flows downward along the drain groove 42, and finally falls into the bottom of the storage chamber 3. At the same time, the screened impurities are intercepted by the screen 43 and moved toward the debris bucket 11 by the movement of the screen 43.

[0037] As the first gear rod 44 rotates, the second gear 48 is synchronously driven to rotate, and the second gear 48 meshes with the second toothed belt 46, thereby forming a synchronous rotation with the first gear 47. The rotation of the first gear 47 drives the abutment rod 49 to rotate. As the abutment rod 49 rotates, the convex block on the surface of the abutment rod 49 abuts against the screen 43 in coordination with the movement of the screen 43, thereby knocking off the debris on the surface of the screen 43. The debris is knocked off and falls into the debris bucket 11 for storage, and the staff can lift and pull the handle at one end of the debris bucket 11 to clean it.

[0038] As the paint accumulates, when the paint level reaches the detection of the water level detector 13, the water level detector 13 sounds an alarm and sends a signal to the microcomputer. The microcomputer receives the alarm signal and controls the electric push rod 7 to extend the telescopic end, thereby pushing the opening and closing plate 8 into the connecting hole 6 to stop the injection of paint.
