Paddy is conveyed into feeding warehouse, and paddy is freely rolled down on the conveyor surface of spiral conveying tube, because of Action of Gravity Field, paddy on conveyor surface from
It is above lower to be freely rolled down；
Step S04：After first paddy has been conveyed, stop motor and the second blower fan, second batch paddy is poured into reserving chamber；
Step S05：Starting shock device, electromagnetic shaker drives spiral conveying tube vibrations, paddy can be prevented to be stuck on conveyor surface, also can
Paddy is allowed to tumble speed quickening, paddy is during being rolled down, and hot blast enters in spiral conveying tube, passes through gas on conveyor surface
Hole is every to paddy to be simultaneously dried；
Step S06：Paddy enters discharging bin after being rolled down, then is transmitted back to feeding warehouse through screw conveyor, and paddy is free again
Roll down on the conveyor surface of spiral conveying tube, paddy is freely rolled down from top to down on conveyor surface again, and hot blast passes through spiral shell
Stomata is every to paddy for the second time on the conveyor surface of rotation delivery pipe is simultaneously dried；
Step S07：Repeat step SO5 and SO6, are repeatedly dried to the first paddy, are reached and are dried after requirement, stop auger defeated
Machine is sent, starts outlet valve, paddy just can carry out draw operation by outlet valve；
Step S08：During drying, air exhauster walks the Abgasabsaugung dried in buffering chamber, logical into inverted U-shaped air draft
Road, after the processing of waste gas removing dust device, waste gas carries out secondary utilization, and the second batch paddy in reserving chamber is dried；
Step S09：After first paddy is unsnatched, repeat step S02, step S03, step S04, step S05, step S06, step
Rapid S07 and step S08, it is possible to complete the work of second batch rice drying；Circulate according to this, it is possible to uninterruptedly paddy is done
Dry work.
The method of the present invention is further, and the air exhauster operational mode of the step S01 has two kinds：Pattern one：Control is taken out
Stop after the fan operation scheduled time, restart air exhauster after stopping the scheduled time, work is circulated according to this；Pattern two：It is logical
Cross measure and dry humidity in buffering chamber, when humidity reaches higher limit, start air exhauster, after a period of time exhausting, dry slow
When humidity reaches lower limit in storage, air exhauster is closed, work is circulated according to this.
The method of the present invention is further, and the electromagnetic shaker operational mode of the step S05 has two kinds：Pattern one：Control shake
The uninterrupted vibrations of dynamic device；Pattern two：Stop after controlling the electromagnetic shaker operation scheduled time, opened again after stopping the scheduled time
Dynamic electromagnetic shaker, circulates work according to this.
One of core element of the technology of the present invention is that first paddy is screened using the second blower fan, also right in screening process
Paddy is dried, so as to improve drying efficiency, reduces useless energy consumption；Helical structure is being made full use of, paddy is being allowed in spiral transferring
Send and be freely rolled down from top to down on the conveyor surface of pipe, hot blast enters in spiral conveying tube, and hot blast passes through the gas on conveyor surface
Hole carries out fully drying to paddy per one side, and hot gas in pipe when circulating, and heat conduction is to conveyor surface, the rice also rolled to conveyor surface
Paddy is dried, and can so do raising drying efficiency, also reduce energy consumption；Dust arrester is recycled to handle waste gas, waste gas
Recycled, the next group paddy in reserving chamber is carried out predrying.Instant invention overcomes existing by conveying device table
Face sets the drawbacks of heating plate is to realize course of conveying heat drying, further improves efficiency.
In one embodiment of the invention, the bottom of the feeding warehouse 5 be paddy in inclined plane, such feeding warehouse 5 can from
By the discharging opening for being slipped to feeding warehouse 5；The angle that the spiral conveying tube 22 is formed with horizontal plane is 30 ~ 70 degree, for example, can be
30th, 35,40,45,50,55,60,65,70 degree etc., the speed that the bigger paddy of angle is freely tumbled is faster, can improve paddy defeated
Efficiency is sent, angle is not illustrated here；The outlet valve 8 is arranged with a charge car 13, and such paddy goes out from outlet valve 8
Proceeded directly to when storehouse in charge car 13, improve paddy and transport efficiency.
In a word, method of the invention is by being provided with reserving chamber, buffering chamber and screw conveyor being dried, first with the second wind
Machine carries out screening and predrying to reserving chamber toward paddy in screw conveyor conveying, and paddy is transported to charging through screw conveyor
Storehouse, is provided with a spiral conveying tube drying in buffering chamber, makes full use of spiral way, allow paddy in the conveying of spiral conveying tube
Freely roll from top to down on face, set and be provided with the outside of stomata, and dry buffering chamber on the conveyor surface of spiral conveying tube
Heating wire and the first blower fan, by the first blower fan toward hot blast is sent into spiral conveying tube, hot blast is by stomata to spiral conveying tube
Conveyor surface on paddy be dried, and hot gas in pipe when circulating, and heat conduction is to conveyor surface, the paddy also rolled to conveyor surface
It is dried；The present invention cleverly utilizes hollow wind-guiding cylinder, and hot gas is sucked by the middle shaft part of warehouse and discharged, the air discharge structure
Coordinate spiral conveying tube, not only realize the gas blown out in warehouse on comprehensive exhaust, particularly spiral conveying tube, can be effective
By the moisture dried out suck discharge；And using the drying buffering chamber that tank skin is hollow air exhausting structure, hot gas will be dried
Blown from tank skin into tank, then coordinate dry hot gas to be blown out from spiral conveying tube, drying efficiency can be substantially increased, overcome existing
There is board-like surface heated drawback；And by setting air exhauster, the Abgasabsaugung with moisture that will can be dried in buffering chamber, this
Sample can be accelerated to dry the flow velocity of buffering chamber apoplexy, improve drying efficiency, and carry out rice drying once, and rice drying will not reach
Required to regulation, paddy is transmitted back in dry buffering chamber by screw conveyor again carries out secondary or three operations, so as to rice
Paddy fully dry；And the waste gas that air exhauster is extracted out is recycled after depositing dust is handled, to next group in reserving chamber
Paddy carries out predrying, raising drying efficiency, reduces energy loss, reduces cost.
The foregoing is only presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, should all belong to the covering scope of the present invention.
