The working principle is as follows: when the device works, the closing cover 7-1 is pushed open to expose the upper end of the U-shaped filter plate 3-1, then cleaned grains are placed into the U-shaped filter plate 3-1 from the upper part of the U-shaped filter plate 3-1, and then the closing cover 7-1 is reset to close the upper end of the U-shaped filter plate 3-1, so that the grains are prevented from being separated from the device from the upper end of the U-shaped filter plate 3-1 during working;
then, a fourth fan 7-2 is started to generate air flow from the upper end to the lower end of the U-shaped filter plate 3-1, the grains are dried through the air flow, water attached to the surfaces of the grains is blown downwards and leaves the equipment from the bottom surface of the U-shaped filter plate 3-1, and therefore the workload of subsequent air drying work is reduced, and the air drying efficiency is further improved;
then, starting a motor to drive a rotating wheel 1-2 to rotate, and further, driving a mounting plate 1 to make clockwise circular motion by the rotating wheel 1-2 through a bearing shaft 1-1, (as shown in fig. 2), taking the leftmost position of the mounting plate 1 in the motion process as a point a, then taking each ninety degree motion as a node, wherein the nodes are respectively a point b, a point c and a point d, wherein in the process from the point a to the point c, equipment drives grains to move rightwards (in the process, the whole grains move rightwards), and in the process from the point c to the point a, the equipment drives the grains to move leftwards and upwards (in the process, the grains can be overturned, so that the part with higher density in the grains, namely the part with higher humidity, moves leftwards relative to the whole grains, and further, the grains with different humidities are separated, and the grain position with higher humidity is closer to the left); for convenience of description, the above two movements are respectively referred to as: right and left;
then, with the clockwise circular motion of the mounting plate 1, firstly, when grains in the U-shaped filter plate 3-1 move rightwards, the grains enter the upper end of the first screening plate 2-1 from the feed chute 3-2, and then when the grains are turned upwards leftwards, the grains are blocked by the side wall of the U-shaped filter plate 3-1 and cannot return to the U-shaped filter plate 3-1 because the upper end of the first screening plate 2-1 is turned upwards, and further grains are left at the upper end of the first screening plate 2-1, so that the grains in the U-shaped filter plate 3-1 continuously enter the upper end of the first screening plate 2-1 from the feed chute 3-2 (it is noted that as the gravity of the grains at the upper end of the first screening plate 2-1 becomes larger, the pressure of the first screening plate 2-1 on the first spring 2-13 is larger, the compression amount of the first spring 2-13 is larger, further, the downward movement amount of the first screening plate 2-1 relative to the mounting plate 1 is larger, the first screening plate 2-1 drives the first screening plate 2-1 to drive the first spring 2-3 to gradually increase, and the gravity of the first screening plate 2-1 does not plug the upper end of the first screening plate 2-1, and the upper end of the first screening plate 2-1 does not plug the first screening plate 2-1, and then the upper end of the first screening plate 2-1 is completely; the continuous increase of the grains with large humidity at the upper end of the first screening plate 2-1 is prevented, the drying efficiency of the first screening plate 2-1 to the grains is prevented from being influenced, meanwhile, the excessive grains at the upper end of the first screening plate 2-1 are prevented, so that the grains which do not reach the drying effect fall to the upper end of the second screening plate 2-5 through the first discharge opening 2-4 under the extrusion of the newly increased grains, affecting subsequent drying efficiency);
then the wind power of the first fan 4-1 blows the grains at the upper end of the first screening plate 2-1 from the lower part to the upper right part through the second vent hole 2-12-1 and the first vent hole 2-1 to dry the grains, and the grains are continuously vibrated under the action of the wind power to enable the grains with large density to be more easily precipitated downwards, and meanwhile, the grains with large humidity are concentrated on the lower layer by matching with the action of turning up to the left, further, the wind power of the first fan 4-1 can act on the grains with large humidity for the first time, the wind power of the first fan 4-1 can consume the moisture in the grains to the maximum extent (the grains with higher humidity under the action of the same wind power, the more water is consumed, the more grains close to a wind source are simultaneously subjected to larger wind force), and the grains are continuously driven by the first screening plate 2-1 to turn left to enable the grains with low humidity to lean right, and when the humidity of the grains leaning right is lower than a threshold value, the grains can overflow the first baffle 2-2 under the self movement and the extrusion of the grains on the left side in the process of moving right and fall onto the upper end of the second screening plate 2-5 through the first discharge opening 2-4 (when the humidity of the grains is higher and turns left, the larger the leftward movement amount is, the humidity of the grains is lower than the threshold value, the grains are far away from the first baffle 2-2 and cannot pass through the first baffle 2-2 in the process of moving right);
when the grains fall to the upper end of the second screening plate 2-5 from the first discharge port 2-4, the completely dried grains move rightwards and fall from the first discharge port 2-8 under the action of the right wind force of the second fan 4-2, and the undried grains move leftwards and fall into the left end of the conveyor belt 2-9 under the action of the left turning (in the action of the left turning, the grains with higher humidity have larger displacement leftwards, and under the action of the right wind force of the second fan 4-2, the grains with lower humidity have larger displacement rightwards;
after the grains fall into the left end of the conveyor belt 2-9, the third fan 6-2 continuously blows air upwards to dry the grains, the conveyor belt 2-9 drives the grains to move rightwards, the grain is driven to move leftwards by the left-turning action, the larger the humidity of the grains is, the larger the left-turning action drives the grain to move leftwards, correspondingly, after the grains are completely dried, the left-turning action drives the grain to move leftwards to be smaller than the right-moving action of the conveyor belt 2-9 driving the grains, the grains are separated from the equipment through the second discharge port 2-10, and meanwhile, the dried grains falling from the first discharge port 2-8 are separated from the equipment through the second discharge port 2-10.
It should be noted that as the grain at the upper end of the conveyor belt 2-9 increases, the weight of the conveyor belt 2-9 increases, and further, the pulling force of the conveyor belt 2-9 pulling the second sliding plate 5-5 downwards becomes larger, and the pulling force of the connecting rod 5-6 to the supporting plate 2-11 becomes larger; meanwhile, the extrusion force of the wedge surface at the left end of the supporting plate 2-11 extruding the third baffle 5-1 downwards is increased, when the weight of the grain at the upper ends of the conveyor belt 2-9 and the first screening plate 2-1 reaches a threshold value, the extrusion force of the wedge surface at the left end of the supporting plate 2-11 extruding the third baffle 5-1 downwards can drive the third baffle 5-1 to move leftwards, so that the second spring 5-3 starts to compress, the heavier the weight of the grain at the upper ends of the conveyor belt 2-9 and the first screening plate 2-1 is, the larger the compression amount of the second spring 5-3 is, the larger the left movement amount of the third baffle 5-1 is, correspondingly, the larger the downward movement amount of the supporting plate 2-11 is, the larger the downward movement amount of the first screening plate 2-1 is, the larger the downward movement amount of the closing plate 2-1-3 is, the larger the blocked part of the feeding groove 3-2 is, the smaller the feeding amount of the U-shaped filter plate 3-1 to the upper end of the first screening plate 2-1 is, so that the feeding speed of the equipment is adjusted, the phenomenon that excessive material is accumulated on the upper end of the conveyor belt 2-9 to influence the stable operation of the equipment is avoided (meanwhile, as the material accumulated on the upper end of the conveyor belt 2-9 becomes more, the conveyor belt 2-9 moves downwards under the action of gravity, the distance from the third fan 6-2 to the upper end of the conveyor belt 2-9 is reduced, and further, the air drying effect of the third fan 6-2 on grains is improved, so that the consumption of the grains on the upper end of the conveyor belt 2-9 is accelerated).
