Discharging pipe 4 runs through screening jar 1 bottom center department, slewing mechanism is constituteed to both, and discharging pipe 4's top and inner tank 5 are linked together, inner tank 5's diapire is honeycomb structure, inner tank 5 is at whole pivoted in-process, the honeycomb hole department that the less seed of granule can follow inner tank 5 bottom spills, discharge from row cinder notch 3 along the slope direction of screening jar 1 bottom, after screening a certain period, control valve 6 opens, the plump seed of granule that the screening was accomplished just can spill from discharging pipe 4, because discharging pipe 4 wholly is located screening jar 1 and inner tank 5's center department, and discharging pipe 4 is rotatable on screening jar 1, therefore discharging pipe 4's existence can not influence inner tank 5's rotation.

The top end of the stirring shaft 71 is provided with a first bevel gear 72, two ends of a transverse shaft 74 are both fixed with second bevel gears 73, and the top end of the driving shaft 8 is fixed with a third bevel gear 76.

The second bevel gears 73 at the two ends of the transverse shaft 74 are respectively meshed with the first bevel gear 72 and the third bevel gear 76, the top end of the stirring shaft 71 penetrates through the top wall of the screening tank 1, the driving motor 9 can drive the third bevel gear 76 to synchronously rotate through the driving shaft 8, the stirring shaft 71 is driven to rotate in a direction opposite to the rotation direction of the driving shaft 8 through the third bevel gear 76 and the meshing transmission in front of the right second bevel gear 73 under the rotation action of the transverse shaft 74, and the stirring shaft 71 is driven to rotate in a direction opposite to the rotation direction of the driving shaft 8 through the first bevel gear 72 by the left second bevel gear 73, so that the twisted dragon plate 7 circularly raises seeds in the inner tank 5.

Special-shaped gear 81 is installed to the half section down of drive shaft 8, and special-shaped gear 81 and drive rack 82 are to the meshing, and drive rack 82 welds the outer wall at inner tank 5, the rotation of drive shaft 8 can drive special-shaped gear 81 simultaneously and rotate, one of them avris of special-shaped gear 81 is equipped with the latch, and the opposite side is the less plain noodles of radius then, consequently when latch and drive rack 82 on special-shaped gear 81 were meshed mutually, special-shaped gear 81 can drive inner tank 5 and carry out synchronous rotation, can drive ball 11 simultaneously and roll before layer board 10, make inner tank 5 pivoted more smooth and easy.

The inner side of the sleeve 12 is provided with a return spring 121, the other end of the return spring 121 is fixed on a return rod 122, and the bottom end of the return rod 122 is welded with the inner wall of the screening tank 1.

Sleeve 12 and the release link 122 that is located sleeve 12 inside are the arc structure, both are sliding connection, and 2 arc structure and inner tank 5's cross-section is concentric, and sleeve 12, reset spring 121 and release link 122 all are about the equal angular distribution of inner tank 5's center, inner tank 5 is at the pivoted in-process, can drive release link 122 towards the inside direction removal of sleeve 12, can cause the extrusion to reset spring 121 simultaneously, when special-shaped gear 81 and drive rack 82 break away from the meshing, make inner tank 5 pivoted effort disappear, reset spring 121's resilience performance just can push up release link 122 and the whole reversal of inner tank 5, until drive rack 82 and special-shaped gear 81 mesh once more, thereby make inner tank 5 endless rotation and gyration, improve the efficiency of seed screening.

A fixed block 141 is installed inside the impurity removing chamber 14, and a material channel 142 which is distributed in a downward inclination manner is opened in the fixed block 141.

The top and the bottom of material passageway 142 are linked together with the inner space of feeder hopper 15 and edulcoration room 14 respectively, and material passageway 142 is the angular distribution in fixed block 141, the seed that falls down from lifting machine 13 top can reach the top of fixed block 141 through feeder hopper 15, because the top in fixed block 141 is the arc structure, consequently the seed can be rolled to material passageway 142 by oneself, then continue the whereabouts along material passageway 142, and angular distribution such as material passageway 142 has a plurality ofly, therefore the seed can be more dispersed whereabouts in edulcoration room 14.

The fan 16 and the air outlet 161 are symmetrically distributed on the side wall of the impurity removing chamber 14, the fan 16 and the air outlet 161 are both located below the fixing block 141, the air outlet 161 is connected with a dust collecting cloth bag 162 through threads, in the falling process of the seeds, the fan 16 blows the falling seeds, weeds and dust in the seeds are promoted to enter the dust collecting cloth bag 162, and the screened and dedusted seeds are discharged from the discharge port 17.

The working principle is as follows: firstly, unscreened seeds are put into the inner tank 5 from the feed inlet 2, as shown in fig. 1-2, the operation of the driving motor 9 drives the third bevel gear 76 to synchronously rotate through the driving shaft 8, the left second bevel gear 73 drives the stirring shaft 71 to rotate in a direction opposite to the rotation direction of the driving shaft 8 through the meshing transmission between the third bevel gear 76 and the right second bevel gear 73 and the rotation of the transverse shaft 74, while the rotation of the packing auger plate 7 drives the seeds to move upwards, and fall down when the seeds move to the top end, and the seeds below are driven to move upwards by the packing auger plate 7;

as shown in fig. 2-3, the rotation of the driving shaft 8 will drive the shaped gear 81 to rotate, one side of the shaped gear 81 is provided with a latch, and the other side is a smooth surface with a smaller radius, so when the latch on the shaped gear 81 is engaged with the driving rack 82, the shaped gear 81 will drive the inner tank 5 to rotate synchronously, the inner tank 5 will drive the reset rod 122 to move towards the inner direction of the sleeve 12 during the rotation process, and will squeeze the reset spring 121, when the shaped gear 81 is disengaged with the driving rack 82, the acting force of the inner tank 5 will disappear, the resilience of the reset spring 121 will push the reset rod 122 and the inner tank 5 to rotate reversely, until the driving rack 82 is engaged with the shaped gear 81 again, so as to make the inner tank 5 rotate circularly and rotate, the matched seeds will rise and fall under the driving of the auger plate 7, the seeds with shriveled particles can more fully leak out from the honeycomb holes at the bottom end of the inner tank 5;

as shown in fig. 2 and 6-7, after the seeds are sieved for a certain time, the control valve 6 is opened, the seeds with full particles after sieving leak out from the discharge pipe 4 to the hoister 13, the hoister 13 operates to convey the sieved seeds into the impurity removing chamber 14, the seeds pass through the feed hopper 15 and reach the upper part of the fixed block 141, and the top end of the fixed block 141 is in an arc-shaped structure, so the seeds roll into the material channel 142 and then continuously fall along the material channel 142, and the material channels 142 are distributed in an equiangular and dispersive manner, so the seeds can fall in the impurity removing chamber 14 in a more dispersive manner, and in the falling process of the seeds, the fan 16 operates to blow the falling seeds, so weeds and dust in the seeds enter the dust collecting cloth bag 162, and the seeds after sieving and dust removing are discharged from the discharge port 17.
