The advantage of this programme is: gravity door and intermittent control shaking sieve the mode adopting and link, namely when the cereal on gravity door reaches a certain amount of, open forcing gravity door to overcome the active force of stage clip, drivening rod swings by the rotation of gravity door, the swing of connecting rod will drive intermittent control shaking to sieve with pin joint as a spot wobble, thus the cereal fallen on intermittent control shaking sieve cleaned by the first suction channel is delivered into the second suction channel, cereal is in course of conveying, large assorted sieve from intermittent control shaking wherein falls, the cereal be sieving through is via the selection by winnowing of the second suction channel, cleaner.
Further, be connected with adjusting screw(rod) in the sidewall thread of described feeding cylinder, one end of stage clip is fixed on the bottom of gravity door, and the other end is fixed on the end of adjusting screw(rod).By rotating the thrust of the adjustable stage clip of adjusting screw(rod).
Further, described intermittent control shaking sieve is pawl sieve, by the effect of pawl, is fed forward cereal when being conducive to shaker vibration.
Further, the first described expansion chamber and the baffle for separating of the second expansion chamber by vertically moving up and down, the first frustum is respectively equipped with in the both sides of dividing plate, two sidewalls that first expansion chamber is relative with the second expansion chamber include riser and are supported on the swash plate on riser top, the upper surface of swash plate has the swash plate inclined-plane matched with the first frustum tapering, and swash plate inclined-plane and the first frustum offset.By regulating dividing plate, dividing plate being moved up and down the swash plate in the first expansion chamber and the second expansion chamber just can be forced to move obliquely or obliquely, thus change the cross-sectional area of the first expansion chamber and the second expansion chamber, to adapt to the sedimentation of different size impurity.
