The core idea of the invention is that the non-deslagged rice grains are transported longitudinally by means of longitudinal flights 126 to increase the utilization of the filtering space.

The rice grains in the rice bin chamber 125 are laterally shifted by the lateral shifting piece 128 on the longitudinal spiral piece 126 so that the rice grains have a lateral centrifugal force, so that a portion of the rice can overflow from the rice channel 129 into the innermost partitioned chamber 122 driven by the centrifugal force.

The rice grains are not directly filled into the separated cavity 122 but are gradually stirred by the transverse stirring sheet 128 in a mode that when the longitudinal spiral sheet 126 rotates for one circle, the transverse stirring sheet 128 stirs the rice into the rice dividing through groove 129 once, and the stirring amount of each time is basically the same, so that the quantitative gradual filtering of the rice is realized, and the condition of incomplete filtering is reduced.

And when the rice flies out of the rice dividing through groove 129 under the centrifugal force, the rice grains have an initial velocity of transverse flying, and the rice grains are partially separated due to the difference of the mass or the initial velocity, so that the rice grains in the partially separated state are subjected to the upward blowing airflow formed by the negative pressure cavity 132, and a part of the chaff with lighter mass can be directly adsorbed in the process.

As shown in fig. 1, 2 and 3, the control valve passage 13 includes a sealing member 131 mounted on the top end surface of the separation cavity 122, and an air inlet 135 is opened on the bottom end surface of the separation cavity 122; the center of the sealing part 131 is provided with a negative pressure cavity 132 for sucking chaff in the centrifugal process, the outer edge of the negative pressure cavity 132 is uniformly connected with a horizontal throwing cylinder 133, the inner cavity of the horizontal throwing cylinder 133 is communicated with the inner cavity corresponding to the separation cavity 122, rice throwing paths of the horizontal throwing cylinders 133 on different sealing parts 131 are not interfered with each other, and the end parts of the horizontal throwing cylinders 133 are movably provided with automatic control valves 134. The self-control valve 134 is a magnet with the top end hinged to one side of the end face of the horizontal projectile barrel 133, and the magnet can be attached to the end face of the horizontal projectile barrel 133 under the action of the magnetic force of the magnet.

During the process of separating the chamber 122 by the rice grains, a portion of the chaff is pretreated.

The remaining rice particles slide on the inner wall of the separation chamber 122 under the centrifugal force of the rotation of the separation chamber 122, so that part of the rice is driven by the centrifugal force to gradually pass through the slag passing hole 123, and is divided into a plurality of regions according to the particle diameter of the rice, for example, the innermost separation chamber 122 is used for filtering and storing stones, impurities and the like with larger diameters, and can be directly discharged outwards from the bottom end of the innermost separation chamber 122.

While the rice grains in the different regions have substantially the same diameter.

Rice grains in different areas are independently operated, the only outlet of the rice grains limited in the area in the separation cavity 122 is the top end, firstly, the separation cavity 122 rotates at a certain speed, so that the husks with the lightest mass in the area move to the top end, the husks can be directly sucked out through the negative pressure cavity 132, then the rotating speed of the negative pressure cavity 132 is continuously increased, at the moment, the negative pressure cavity 132 is closed, the rice grains with the lightest mass under the same grain size move to the top end of the negative pressure cavity 132 until the rice grains are thrown out of the horizontal throwing cylinder 133, therefore, the rice grains in the horizontal throwing cylinder 133 are subjected to the same air resistance force due to the similar grain size, and therefore, the rice grains perform parabolic motion under the action of gravity and the initial speed, and further realize the secondary separation process of the same grain size according to the mass.

According to the scheme, medium-quality particles and high-quality particles are sequentially thrown out.

So this scheme can realize that the first separation according to the diameter size of rice slagging-off in-process, and the rethread centrifugation realizes the first separation according to the quality, realizes the secondary separation of quality through the parabola motion at last.

As shown in fig. 1 and 4, an inner cavity 23 is formed in the tapered groove 21, an air blower 24 for blowing rice falling into the tapered groove 21 in a reverse direction to reduce a falling speed of the rice is installed in the inner cavity 23, an electric heating wire is installed in the inner cavity 23, an air outlet 25 is formed in a top end of the inner cavity 23, and a falling prevention filter screen 26 is fixedly installed in the air outlet 25. At least two mounting grooves 27 are formed in the vertical groove wall of the conical groove 21, a vibration plate 29 is horizontally mounted in each mounting groove 27 through an elastic piece 28, a vibration motor 210 is mounted on one side of each mounting groove 27, an eccentric shaft of each vibration motor 210 is fixedly connected with the vibration plate 29, meter-passing slots 211 are formed in the vibration plates 29 at equal intervals, and the meter-passing slots 211 in adjacent vibration plates 29 in the same conical groove 21 are staggered.

Reduce the falling velocity of rice granule through updraft to reduce the damage of rice granule, vibrate the vibration of piece 29 at last, make the rice granule stand the high-frequency vibration of small range, thereby make the rice can vibrate by the stubborn dust on surface and open, thereby the updraft of single direction motion blows away, discharges to the external world, thereby realizes that the rice divides the dust removal step of sediment in-process.

An annular sand retaining groove 14 is formed in the inner wall of the slag separating kettle 11.

Because the small volume of sand is bigger than that of rice in the rice grains, the centrifugal force applied to the sand grains is far larger than that of the rice grains under the same rotating speed, so that the sand is thrown off and directly flies to the inner wall of the slag separating kettle 11 to be collected by the annular sand retaining groove 14, and self-adhesive glue can be coated on the inner wall of the slag separating kettle 11 to prevent the sand from rebounding due to collision.

The clogging of the slag separating hole 123 is prevented by the rotation of the scraping plate 1211.
