Principle of work:

Start the power supply of control unit 34, under the programming control of control unit 34, drive main motor 1 and helper motor 35 runnings, make the turned position of little bend pipe 17 be returned to initial condition.When grain does not arrive grain inlet 36, supplied materials coil pickup 37 sends the supplied materials signal for control unit 34, cloth grain machine only rotates under the driving of main motor 1 and keeps the initial position of little bend pipe 17 constant, after grain arrives grain inlet 36, supplied materials coil pickup 37 sends the supplied materials signal for control unit 34, control unit 34 sends control signal according to program to helper motor 35 after receiving the supplied materials signal of supplied materials sensor, the velocity of rotation of helper motor 35 makes the rotational line speed of two gears 30 equate with the rotational line speed of the first gear ring 6 by 31 decelerations of assisted deceleration machine or produces difference, with the location status according to the little bend pipe 17 of programming control that designs.Grain enters big syphon 12 from grain inlet 36 and runs to little bend pipe 17 along big syphon 12, under the effect of little bend pipe 17, change sense of motion, grain is transported to the position of setting, realize when without the supplied materials signal thus, cloth grain machine only rotates under the driving of main motor 1 and does not change the location status of little bend pipe 17, when the supplied materials signal is arranged, cloth grain machine both rotated, change again the location status of little bend pipe 17, assisted deceleration machine 31 connects together by the output shaft of coupler 32 with helper motor 35, control by control unit 34, when not needing to adjust the direction of little bend pipe 17, make the linear velocity of the second gear 30 runnings the same with the linear velocity of the first gear ring 6 runnings, such the second gear ring 7 does not just have relative motion with respect to the first gear ring 6, and the 3rd gear 29 relative the second gear rings 7 do not relatively rotate yet, and can rotate with the first gear ring 6, keep the 4th gear 25 not rotate, thereby keep little bend pipe 17 not rotate; When needs are regulated the Way out of little bend pipe 17, make the linear velocity of the second gear 30 runnings and the linear velocity of the first gear ring 6 runnings that a difference (or being faster or slower than) be arranged, such the second gear ring 7 just has with respect to the first gear ring 6 and relatively rotates, the 3rd gear 29 will rotate, driving the 4th gear 25 rotates, thereby little bend pipe 17 is rotated, change its Way out; After above-mentioned action, big syphon 12 lower ends are provided with the little bend pipe 17 of a bending, little bend pipe one end and the socket of big syphon lower end, little bend pipe 17 can rotate around the turning cylinder of tuning bearing 16 under the 4th gear 25 drives by external tooth and 25 engagements of the 4th gear of the 3rd gear ring 21.Because the rotation of little bend pipe 17 so that grain when flowing out little bend pipe 17 direction change, when little bend pipe 17 Way outs are upper for being tilted to, the Flowing of Grain track is oblique upthrow, grain level run larger distance, and grain drops to apart from zone far away, the circular grain face center of circle; When little bend pipe 17 Way outs for being tilted to lower time, the Flowing of Grain track is tiltedly lower throwing, and throwing the grain direction is not to point to circumference along radial direction, cause grain along the short distance of radial direction level run, fall apart from nearer zone, the center of circle of grain face, thereby control grain fall area, alleviate the automatic classification of grain and impurity, because the grain moving velocity is the flow velocity that relies on grain to form from the conveyer free fall, rather than hasten by leading the motion that grain pipe High Rotation Speed produces, therefore do not need very large driving power, keeping slowly, velocity of rotation just can reach the purpose of disperseing grain.
