The planetary driven variable-inclination variable-speed imitation manual water screen type green shaking machine according to claim 1, wherein the planetary driven variable-inclination variable-speed imitation manual water screen type green shaking machine is characterized in that: one end of the eccentric wheel lower plate, which is far away from the cam, is provided with a slideway; the length direction of the slideway is parallel to the spring column; the balancing weight and the slideway form a sliding pair and are connected with a bolt penetrating through the slideway.
9. The planetary driven variable-inclination variable-speed imitation manual water screen type green shaking machine according to claim 1, wherein the planetary driven variable-inclination variable-speed imitation manual water screen type green shaking machine is characterized in that: two ends of the rotating shaft and two second bearing seats respectively form a revolute pair, and the second bearing seats are fixed on the cradle; the cradle and the support shaft are fixed through a flange plate; the support shaft and the bearing seat III form a revolute pair, and the bearing seat III is fixed with the frame.
10. The planet-driven variable-inclination and variable-speed imitation manual water screen type green rocking method of the green rocking machine according to any one of claims 1 to 9, wherein the green rocking method is characterized by comprising the following steps of: the method comprises the following steps:
the motor is started, the motor drives the planetary gear train transmission mechanism through the non-circular gear transmission mechanism, the planetary gear train transmission mechanism drives the cam transmission mechanism and the screen disc rotation mechanism to revolve around the circumference, and the cam in the cam transmission mechanism rotates while the cam transmission mechanism revolves; in the cam transmission mechanism, the cam rotates to drive the joint bearing, the connecting plate and the spring column to slide along the spring seat, and the restoring force of the spring column to the joint bearing is combined, so that the inclination angle of the screen disc rotating mechanism connected with the inner ring of the joint bearing through the spherical hinge plug is periodically changed while the screen disc rotates, and the revolution speeds of the planetary gear train transmission mechanism, the cam transmission mechanism and the screen disc rotating mechanism are periodically changed due to the non-uniform transmission characteristic of the non-circular gear transmission mechanism, and the periodic speed change revolution of the screen disc in the screen disc rotating mechanism is finally realized; in the screen disc rotating mechanism, although a screen disc shaft fixed at the bottom of the screen disc and a hollow sliding shaft form a sliding pair, the hollow sliding shaft is detachably and fixedly connected with a spherical hinge plug fixed in an inner ring of a joint bearing, and the joint bearing is the spherical pair, the screen disc shaft is locked for autorotation by a rotating shaft and a supporting shaft which are vertically arranged, so that the screen disc is ensured not to autorotate.
