the jarring mechanism comprises a fixed rod (33), a connecting rod (34) and a plurality of gravity balls (19), the gravity balls (19) are driven to do lifting movement in the inner cavity of the cylinder (4) when the cylinder rotates, and the gravity balls (19) hit the filter material net (32) after falling down;
both ends of the fixed rod (33) are fixedly connected with the inner wall of the roller (4), one end of the connecting rod (34) is connected with the fixed rod (33), the other end of the connecting rod is fixedly connected with the inner wall of the end part of the roller (4), a plurality of gravity balls (19) are arranged, and the gravity balls (19) are distributed at equal intervals along the axial direction and the circumferential direction of the connecting rod (34);
a gravity ball (19) is arranged in the roller (4), the gravity ball (19) moves towards the discharging end of the roller (4) under the action of axial force of the roller (4), when the roller (4) rotates, the gravity ball (19) moves upwards under the drive of the gravity ball, then falls under the action of gravity, and directly hits a filter material net (32), so that the crushing of materials is realized, the full automatic discharging of the coating is ensured, manual treatment is not needed, and the filter material net (32) vibrates under the shock effect of the gravity ball (19) to apply downward force to the coating, so that the blocking of a filter hole is prevented;
a valve plate (14) is arranged in the roller (4), the valve plate (14) is rotatably arranged in the inner cavity of the roller (4) through a valve rod (15), the valve plate (14) divides the inner cavity of the roller (4) into a stirring grinding area (17) and a blanking area (18), and a coating channel is formed between the stirring grinding area (17) and the blanking area (18);
the high-speed stirring grinder is arranged in a stirring grinding area (17), a discharging opening (6) is arranged in a discharging area (18), a flow motor (16) is arranged outside the roller (4), an output shaft of the flow motor (16) is connected with a valve rod (15) in a driving mode, and a valve plate (14) rotates along with the valve rod (15) and opens or closes a coating channel.
2. The efficient grinding device for water-based paint according to claim 1, wherein: the outside of the roller (4) is provided with a transmission structure, the transmission structure is used for driving the roller (4) to rotate, the transmission structure comprises a first conical tooth (20), a second conical tooth (21), a rotating gear (22) and a driven gear (23), the first conical tooth (20) and the second conical tooth (21) are meshed with each other, and the rotating gear (22) and the driven gear (23) are meshed with each other;
the bottom of transmission shaft (8) extends to cylinder (4) outside, and first awl tooth (20) is at the bottom fixed mounting of transmission shaft (8), and cylinder (4) outer wall fixed mounting has connecting plate (24), rotates on connecting plate (24) and installs connecting axle (25), and second awl tooth (21) and rotation gear (22) are installed respectively at both ends of connecting axle (25), and driven gear (23) are fixed cup joint with cylinder (4).
