[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 or Figure 2 The present invention provides a technical solution: a multi-layer drying device for agricultural seeds, comprising a multi-layer drying box 1, a climbing feeding device 2 for conveying seeds is arranged on one side of the multi-layer drying box 1, and a discharging device 3 for discharging seeds is arranged on the other side of the multi-layer drying box 1. In order to ensure that the seeds after being soaked will not stick together, a feeding mechanism 4 that can move intermittently can be arranged on the climbing feeding device 2 for feeding seeds, and a spreading mechanism 5 is arranged to spread the input materials;

[0040] In addition, a fresh air supply port 14 is provided on the box body 11 of the multi-layer drying box 1 to supply fresh air to the inside of the box body of the multi-layer drying box 1;

[0041] The box body 11 is also provided with a circulating fan 15, so that the hot air inside the box body of the multi-layer drying box 1 can circulate to achieve comprehensive drying;

[0042] The box body 11 is also provided with a dehumidification fan 16 and an exhaust duct 17 . The moisture generated during drying is sucked away by the dehumidification fan 16 and then discharged through the exhaust duct 17 .

[0043] like Figure 3-5 As shown, in this embodiment, the material spreading mechanism 5 includes a rotating roller 51, and the two ends of the rotating roller 51 are respectively connected to the inner wall of the body of the climbing and feeding device 2, and one end of the rotating roller 51 is extended out of the body and connected to the rotating motor 54.

[0044] Two spirally arranged movable grooves 511 are provided on the rotating roller 51, and the two movable grooves 511 are arranged alternately, and then the sleeve ring 52 is sleeved on the rotating roller 51.

[0045] The inner wall of the ring 52 is rotatably connected with a slider 521, which is embedded in the movable groove 511.

[0046] A bearing seat 522 is then provided at the bottom of the collar 52, and then the paving assembly 53 is installed on the bearing seat 522;

[0047] The paving assembly 53 includes a shaft gear 531 and a cylinder 532.

[0048] Insert the shaft of the shaft gear 531 into the bearing seat 522, and set a connecting piece 533 at the end of the shaft, then install the connecting rod 534 under the connecting piece 533, and finally fix the flat brush 535 under the connecting rod 534.

[0049] Fix the cylinder 532 to the side wall of the collar 52, then take a rack 536 and connect it under the piston rod of the cylinder 532, and ensure that the rack 536 is meshed with the shaft gear 531;

[0050] The material spreading operation mode of the material spreading mechanism 5 is as follows: after the rotating motor 54 is started to drive the rotating roller 51 to rotate, the slider 521 slides along one of the movable grooves 511, thereby driving the collar 52 and the flattening assembly 53 thereunder to move to one side.

[0051] When the collar 52 moves to the end of the side, under the continuous rotation of the rotating roller 51, the slider 521 will slide into another movable groove 511 and continue to slide in the opposite direction, thereby driving the collar 52 and the paving assembly thereunder to move to the other side, that is, realizing the reciprocating movement of the paving assembly 53;

[0052] While the paving assembly 53 is moving back and forth, the cylinder 532 is activated to extend and retract to drive the rack 536 to move back and forth, thereby driving the shaft gear 531 to reciprocate, and at this time, the connecting rod 534 and the paving brush 535 will also swing accordingly;

[0053] The seeds are spread flat by the cooperation of the reciprocating movement and the reciprocating swing of the spreading component 53.

[0054] like Figure 6-7 As shown, in this embodiment, the feeding mechanism 4 includes a lower hopper 41, a baffle 42 and a driving assembly 43, the baffle 42 is arranged at the discharge port 411 of the lower hopper 41, one side of the baffle 42 is installed on the inner wall of the body of the feeding mechanism 4 through a rotating shaft 421, and one end of the rotating shaft 421 extends to the outer side of the body of the feeding mechanism 4 and is connected to the driving assembly 43;

[0055] The driving assembly 43 includes a movable mounting seat 431, an electric screw rod 432 and a second connecting rod 433.

[0056] The movable mounting seat 431 is fixed on the outer wall of the feeding mechanism 4, the electric screw 432 is installed on the movable mounting seat 431, the mover of the electric screw 432 is connected to the second connecting rod 433, and the other end of the second connecting rod 433 is connected to the rotating shaft 421;

[0057] The intermittent operation mode of the feeding mechanism is: start the electric screw 432 to rotate, and then the mover on the electric screw 432 will move back and forth, thereby causing the second connecting rod 433 to swing back and forth.

[0058] When the second connecting rod swings to the right, the rotating shaft is driven to rotate, and the baffle 42 opens;

[0059] When the second connecting rod swings to the left, the rotating shaft is driven to rotate, and the baffle 42 is closed at this time;

[0060] Intermittent material discharge is achieved by switching the baffle at the material discharge port 411 .

[0061] like Figure 8 As shown, in this embodiment, a feed inlet 21 is provided on the body of the climbing and feeding device 2. After the feeding mechanism 4 is docked with the feed inlet 21, the seeds can enter the climbing and feeding device 2 from the feeding mechanism 4;

[0062] The conveyor belt 22 is installed inside the body of the climbing and feeding device 2, and the conveyor belt 22 is arranged in an inclined state, wherein the feeding mechanism 4 and the spreading mechanism 5 correspond to the lower end of the conveyor belt 22, and the upper end of the conveyor belt 22 extends into the multi-layer drying box 1, so as to facilitate the delivery of seeds into the multi-layer drying box 1.

[0063] like Fig. 9 As shown, in this embodiment, the multi-layer drying box 1 includes a box body 11, and a multi-layer conveyor mesh belt 12 and a heating system are arranged in the box body 11. A flattening rake 121 is arranged at the starting end of the conveyor mesh belt 12 on the top layer, and a baffle 122 is arranged at the starting end of each of the remaining conveyor mesh belts 12. The principle of multi-layer utilization of hot air is adopted, and the seeds on each layer of the conveyor mesh belt 12 are dried by the heating system.

[0064] Working principle: the feeding mechanism 4 intermittently puts the soaked seeds into the climbing feeding device 2, and at the same time the spreading mechanism 5 continuously spreads the seeds to achieve flat spreading;

[0065] The seeds after being spread out continue to move upward along the conveyor belt of the climbing feeding device 2, and are finally transported to the multi-layer conveyor mesh belt 12 of the multi-layer drying box;

[0066] Since the starting end of the uppermost conveyor mesh belt 12 is provided with a flattening rake 121, after the seeds fall into the conveyor mesh belt 12, as the conveyor mesh belt 12 moves, the wet seeds will pass through the flattening rake 121 and be flattened again;

[0067] The seeds are initially dried as they move along the top conveyor mesh belt 12. When they move to the end, they fall onto the lower conveyor mesh belt 12 for further drying. Since a baffle 122 is provided at the starting end of each lower conveyor mesh belt 12, the seeds can be prevented from falling into the track.

[0068] Finally, the dried seeds are discharged from the discharging device 3 .

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
