when the drying device is used, firstly, moist grains are guided to the inner cavity of the circulating box body 1 through the hopper 8, the corresponding heating and drying device is arranged in the circulating box body 1, after drying treatment, if the humidity of the grains is reduced to a preset value, the baffle 3 is controlled to rotate to the state of shielding the second outlet 202 through the external controller, so that the dried grains can only enter the collecting box 4 through the first outlet 201 to be stored, and then the dried grains are obtained.
If the humidity of cereal is still great, then control baffle 3 through external controller and rotate to the state of sheltering from first export 201 for moist cereal passes through second export 202 and gets into stereoplasm riser 6 along discharging pipe 5, and rotating electrical machines 14 at this moment drive auger 13 rotatory, makes auger 13 promote the moist cereal in the stereoplasm riser 6, and the cereal gets back to hopper 8 through material return hose 7 again, falls into the inner chamber of circulation box 1 once more, realizes the circulation drying to moist cereal from this.
In the grain circulation process, the rotating motor 14 drives the driving gear 16 to rotate through the auger 13, the driving gear 16 drives the impact balls 18 to rotate through the connecting rod 17, so that the impact balls 18 intermittently impact the sleeve block 19, and the sleeve block 19 drives the return hose 7 to vibrate, so that the phenomenon that wet grains are adhered to the wall of the return hose 7 to cause the blockage of the return hose 7 is avoided; meanwhile, the driving gear 16 drives the driven gear 33 to rotate through the transmission chain 34, the driven gear 33 drives the rotating rods 24 to rotate, the transmission wheel 25 is fixedly sleeved on each rotating rod 24, all the rotating rods 24 rotate under the action of the transmission belt 26, the driving bevel gear 27 is fixedly sleeved on each rotating rod 24, the driving bevel gear 27 drives the driven bevel gear 28 to rotate, the driven bevel gear 28 drives the cam 30 to rotate through the transmission rod 29, when the rotary motor 14 drives the packing auger 13 to continuously rotate, the cam 30 continuously rotates, the cam 30 intermittently presses the hollow plate 9 at the moment, when the cam 30 is far away from the hollow plate 9, the hollow plate 9 is jacked and restored by the first spring 11 and presses the hollow plate 9 again along with the rotation of the cam 30, and therefore, the cyclic reciprocating motion is realized, and in the process: firstly, the hollow plate 9 drives the scraper 35 to move downwards and restore upwards, the scraper 35 can move along the inner wall of the circulating box body 1, and then wet grains adhered to the inner wall of the circulating box body 1 are scraped, so that the grains are prevented from being rotten, mildewed, peculiar smell and the like after being not cleaned for a long time, further the pollution to subsequent processed grains is avoided, and the cleanliness of equipment is improved; secondly, the hollow plate 9 drives the rack 36 to move downwards and restore upwards, the rack 36 drives the rotary gear 37 to rotate, the rotary gear 37 drives the poking plate 39 to rotate through the swinging rod 38, the poking plate 39 can swing along the arc-shaped plate 40 to poke out grains stacked in the arc-shaped plate 40, the raised grains are dispersed in the air and heated, so that the drying coverage is wider, the problem that the drying is not complete due to the traditional stacked grain drying is solved, if the humidity of the grains is higher, the lifting speed of the auger 13 can be adjusted slowly through the rotary motor 14, at the moment, the moving frequency of the poking plate 39 is also reduced, the speed of the grains poked out of the arc-shaped plate 40 by the poking plate 39 is reduced, namely, the time for the grains to stay in the arc-shaped plate 40 is prolonged, so that the grains can be dried for a long time, otherwise, if the humidity of the grains is lower, the auger 13 can be controlled to run at a high speed, at this moment, the material stirring speed of the material stirring plate 39 is higher, the drying processing efficiency of the grains can be effectively improved, and therefore the specific use mode of the material stirring plate can be flexibly adjusted according to the humidity of the grains, and the material stirring plate is more intelligent and stronger in universality.
