DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] The utility model provides a rice seed drying and air separation device, comprising:

[0030] Box body 1, the upper wall of which is fixedly connected to a feed hopper;

[0031] The feed hopper can facilitate the staff to add the rice seeds that need to be winnowed into the box 1;

[0032] A through opening 2 is formed in one side wall of the box body 1;

[0033] The inclined plate 3 is fixedly mounted on one side wall of the box body 1 and is located on one side of the opening 2;

[0034] The collecting box 4 is fixedly mounted on the outer wall of the box body 1 and is located outside the opening 3;

[0035] A sealing door is hinged on one end face of the collection box 4 to seal the collection box 4;

[0036] An air outlet is formed in the upper wall of the collection box 4;

[0037] The heating box 5 is fixedly mounted on the outer wall of the box body 1;

[0038] An air outlet pipe 6, one end of which passes through a side wall of the box body 1, and the other end of which passes through the upper wall of the heating box 5;

[0039] The electric heating wire 7 is arranged in the heating box 5;

[0040] The electric heating wire 7 can heat the air in the heating box 5, and at the same time, under the action of the air outlet pipe 6, the air in the heating box 5 can flow into the box body 1;

[0041] The fan 8 is fixedly mounted on a side wall of the heating box 5, and the air outlet end is connected to the heating box 5;

[0042] The fan 8 can transport the outside air into the heating box 5. At this time, the electric heating wire 7 heats the air. The heated air flows into the box body 1 through the air outlet 6, blowing the rice seeds flowing out of the feed hopper. While the rice seeds are being air-selected, they can also be dried. At this time, the defective rice seeds are blown to the side of the inclined plate 3. The inclined plate 3 can guide the defective rice seeds and make them slide through the opening 2 into the collection box 4 for collection.

[0043] The reciprocating conveying mechanism is arranged on the outside of the box body 1 and is used to convey the rice seeds in the box body 1 to the feed hopper.

[0044] Specifically, the reciprocating conveying mechanism includes:

[0045] The conveying shell 9 is fixedly mounted on the outer wall of the box body 1, with the feed end connected to the lower wall of the box body 1 and the discharge end located above the feed hopper;

[0046] The auger 10 is rotatably mounted in the conveying shell 9;

[0047] The motor 11 is fixedly mounted on the upper wall of the conveying shell 9, and the output end is fixedly connected to one end of the auger 10;

[0048] The output end of the motor 11 rotates to drive the auger 10 to rotate. At this time, the auger 10 can transport the rice seeds into the feed hopper, so that the rice seeds fall into the box body 1 again, and are again air-selected and dried to improve the quality of the rice seeds.

[0049] Specifically, a discharge port 12 is formed at the lower end of one side wall of the box body 1, a flip plate 13 is hingedly connected to the inner wall surface of the box body 1 and located on one side of the discharge port 12, and a bearing block 14 for supporting the flip plate 13 is fixedly installed on the lower end surface of the inclined plate 3;

[0050] The staff puts their hand into the discharge port 12 and pushes the flip plate 13 to flip the flip plate 13 so that one side wall of its upper end contacts the supporting block 14. At this time, the flip plate 13 can guide the rice seeds that fall from the feed hopper so that they flow out of the discharge hopper 12, making it convenient for the staff to collect them.

[0051] Specifically, a filter 15 is fixedly installed in the air outlet;

[0052] The filter screen 15 can prevent the defective rice seeds in the collecting box 4 from flying out of the air outlet, thereby preventing the working environment from being polluted.

[0053] Specifically, a pair of fixing plates 16 are fixedly mounted on the outer wall surface of the box body 1 , and a pair of supporting legs 17 are fixedly mounted on the lower end surfaces of the fixing plates 16 .

[0054] Working principle: First, the staff starts the electric heating wire 7, the fan 8 and the motor 11, and then the staff puts the rice seeds that need to be air-selected into the feed hopper. At this time, the rice seeds in the feed hopper fall into the box body 1. At the same time, the electric heating wire 7 can heat the air in the heating box 5. At this time, the fan 8 can transport the outside air into the heating box 5. At this time, the electric heating wire 7 heats the air, and the heated air flows into the box body 1 through the air outlet 6, blowing the rice seeds flowing out of the feed hopper. At this time, the defective rice seeds are blown to one side of the inclined plate 3. The inclined plate 3 can guide the defective rice seeds so that they slide from the through port 2 into the collection box 4 for collection. At the same time, While the rice seeds are being air-selected, they can also be dried. At this time, the air-selected rice seeds fall to the lower end surface of the box body 1 and fall into the conveying shell 9. At this time, the motor 11 drives the auger 10 to rotate to convey the rice seeds and convey them to the feed hopper again, so that they fall into the box body 1 again and are air-selected and dried again to improve the quality of the rice seeds. After the air selection is completed, the staff puts his hand into the discharge port 12 and pushes the flip plate 13 to flip the flip plate 13 so that one side wall of its upper end contacts the supporting block 14. At this time, the flip plate 13 can guide the rice seeds that fall from the feed hopper so that they flow out of the discharge hopper 12, which is convenient for the staff to collect and brings convenience to people.
