Description

Technical Field

[0001] The utility model relates to the technical field of grain drying and recovery, in particular to a fast recovery device for grain drying. Background Art

[0002] my country is a country with large grain production, and grain dryer is a commonly used grain storage equipment. The existing grain dryer includes: a warehouse body of the dryer, an upper auger installed on the warehouse body, an elevator, a lower auger, and a grain-dividing structure, and a slow-suction warehouse, a drying warehouse, and a recovery warehouse are arranged in sequence from top to bottom inside the warehouse body; during drying, the grain conveying equipment puts the grain into the hopper of the elevator, and the grain is lifted to the top of the warehouse body by the elevator, and the upper auger sends the grain into the warehouse body from the grain inlet at the top of the warehouse body; the grain first falls into the slow-suction warehouse from the grain inlet, and the grain in the slow-suction warehouse slowly moves from top to bottom to the drying warehouse under the action of its own weight, and the grain is heated and dried in the drying warehouse by hot air; the dried grain is buffered and recovered from the bottom of the drying warehouse through the recovery warehouse, and then sent to the funnel-shaped grain hopper through the grain-dividing structure, and the bottom of the grain hopper is the feeding port of the lower auger, and the grain is discharged from the grain hopper to the lower auger; the lower auger transports the grain to the elevator, and then to the upper auger, and so on, and the grain is dried many times, so that the grain is fully dried;

[0003] The existing recovery bin generally has two groups of "V"-shaped guide plates staggered inside to guide the dried grain, which are guided to the grain distribution structure for transportation. During use, due to the different yields of dried grain, the existing guide plates are fixed structures and cannot adjust the spacing according to the yields. This results in grain collisions caused by excessive spacing when the grain yield is small, and grain circulation is blocked by excessive spacing when the grain yield is large. In addition, direct impact of grain on the guide plates may cause grain explosion, resulting in damage and waste. Therefore, we propose a rapid recovery device for grain drying.

The two sets of second guide plates rotate and cooperate with each other with the first shaft as the center, so as to adjust the distance between the second guide plate and the first guide plate. The connecting plate plays a protective role between the two sets of second guide plates. In this way, they can be adjusted and used according to different grain yields to improve the recovery efficiency.

[0015] (2) The rapid recovery device for grain drying cooperates with the internal components of the first recovery component and the second recovery component. The grain impacts the side of the movable plate, and the movable plate is squeezed and slides inside the movable groove. At the same time, the restraining rod slides inside the restraining groove to restrain and guide the movable plate, and the movable plate squeezes the buffer tube to deform and play a buffering role; at the same time, the grain impacts the side of the buffer plate, and the buffer plate is deformed by force to squeeze the support bar to play a buffering role. The deformed bar further strengthens the structural stability of the support bar and improves the supporting effect of the support bar on the buffer plate. In this way, it plays a buffering and protective role for the grain and avoids the damage of the grain. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The working principle of this utility model:

[0030] When in use, the elevator lifts the grain to the slow-moving bin 11, and the grain in the slow-moving bin 11 flows to the drying bin 12 under the action of its own weight. The grain is heated and dried by hot air in the drying bin 12, and the dried grain passes through the recovery bin 13 from the bottom of the drying bin 12, and is then sent to the auger inside the auger bin 14 through the grain-shifting structure. The auger transports the grain to the elevator 15 for lifting and cyclic operation, wherein two sets of oppositely staggered cylinders of the telescopic device 34 supply air to the connecting rod 341, and control the connecting rod 341 to push and pull the two sets of second guide plates 31 to move repeatedly. At the same time, the second rotating shaft 312 is constrained to slide inside the slide groove 32, and the folding plate 321 plays a blocking role as the second rotating shaft 312 slides and deforms, and the two sets of second guide plates 31 rotate and cooperate with each other with the first rotating shaft 311 as the center, so as to adjust the distance between the second guide plate 31 and the first guide plate 21, and the connecting plate 35 plays a protective role between the two sets of second guide plates 31.

[0031] When in use, the grain impacts the side of the movable plate 23, and the movable plate 23 is squeezed and slides inside the movable groove 22. At the same time, the constraint rod 25 slides inside the constraint groove 24 to constrain and guide the movable plate 23. The movable plate 23 squeezes the buffer tube 26 to deform and play a buffering role; simultaneously, the grain impacts the side of the buffer plate 331, and the buffer plate 331 is deformed by force to squeeze the support strip 332 to play a buffering role. The deformation strip 333 further strengthens the structural stability of the support strip 332, thereby improving the supporting effect of the support strip 332 on the buffer plate 331.
