[0032] A feeding component, which is connected to the rotating shaft 11 and is located in the feeding pipe 6, and is used to continuously feed the grain at the bottom of the storage tank 2 to the rotating disk 8; the feeding component includes a special-shaped rod 1401 connected to the rotating shaft 11, the special-shaped rod 1401 is slidably connected to the feeding shaft 1402, and an auger 1403 is installed on the feeding shaft 1402, wherein the special-shaped rod 1401 is slidably connected to the feeding shaft 1402, and when the special-shaped rod 1401 rotates, it can also drive the feeding shaft 1402 to rotate synchronously;

[0033] A baffle plate 20 connected to the bottom end of the feed shaft 1402, wherein the outer wall of the baffle plate 20 is in contact with the inner wall of the feed pipe 6;

[0034] A lifting component 15, wherein the lifting component 15 is connected to the feeding shaft 1402 and is used to adjust the height of the feeding component;

[0035] An outer frame 18, the outer frame 18 is fixedly connected to the feeding shaft 1402, and the outer frame 18 is located in the ventilating cylinder 13, and a fan 19 is disposed on the outer frame 18;

[0036] A stirring member 16, which is disposed on the rotating disk 8 and extends into the storage tank 2, and is used to stir the grain in the storage tank 2;

[0037] A transmission component 17, wherein the transmission component 17 is disposed in the support platform 4 and is used to drive the stirring component 16;

[0038] The control component 24 is disposed at the bottom of the rotating disk 8 and connected to the return material baffle 22 for opening the return material opening 21 .

[0039] The rotating shaft 11 is driven to rotate by the corresponding driving member 10, and the rotating disk 8 is driven to rotate synchronously by the synchronous frame 12. At the same time, the feeding shaft 1402 is also rotated under the drive of the special-shaped rod 1401, thereby driving the auger 1403 to rotate, and then the grain entering from the discharge port 7 at the bottom of the feeding pipe 6 can be transported to the rotating disk 8, and the fan 19 is started. The fan 19 generates suction, so that the air outside the rotating disk 8 enters from the second ventilation hole 9, and then the grain transported to the rotating disk 8 is ventilated and dissipated. With the rotation of the rotating disk 8, the grain transported to the rotating disk 8 will gradually move to the outside of the rotating disk 8 under the action of centrifugal force until the grain enters the return baffle 22 between the two limiting mesh plates 23. The grain is During the rolling process toward the return material baffle 22 under the action of the control component 24, the air entering from the second ventilation hole 9 can fully contact with the part of the grain, thereby achieving a better ventilation and heat dissipation effect. Under the action of the control component 24, after the rotating disk 8 rotates a certain number of times, in order to prevent the grain accumulated on the return material baffle 22 from affecting the air intake effect of the second ventilation hole 9, the control component 24 will open the return material baffle 22, so that the grain on the return material baffle 22 will enter the storage tank 2 again. In addition, during the rotation of the rotating disk 8, the stirring component 16 will be driven by the transmission component 17 to stir the grain in the storage tank 2, so that the grain can be effectively turned over, which not only facilitates the contact between air and grain but also avoids the agglomeration of grain, and the use effect is better.

[0040] In one case of this embodiment, the lifting component 15 includes a lifting plate 1501 rotatably connected to the top of the feed shaft 1402, and both ends of the lifting plate 1501 are equipped with a first telescopic member 1502 connected to the top wall of the rotating disk 8. Preferably, the first telescopic member 1502 is configured as a hydraulic rod.

[0041] In the initial state, the first telescopic member 1502 is in a retracted state. At this time, the baffle plate 20 at the bottom of the feed shaft 1402 will be located below the discharge port 7 on the feed pipe 6, thereby blocking the bottom of the feed pipe 6, so that the food in the storage tank 2 will not be discharged from the bottom when it enters the feed pipe 6 from the discharge port 7, thereby facilitating the auger 1403 to transport the food at the bottom of the storage tank 2 to the rotating disk 8. When the food in the storage tank 2 needs to be discharged, the first telescopic member 1502 can be started. The extension of the first telescopic member 1502 drives the lifting plate 1501 to rise, thereby driving the feed shaft 1402 to rise, so that the baffle plate 20 at the bottom of the feed shaft 1402 rises to above the discharge port 7. At this time, the food discharged from the discharge port 7 can be discharged from the bottom of the feed pipe 6.

[0042] In one case of this embodiment, the stirring component 16 includes a plurality of movable shafts 1601 rotatably arranged on a rotating disk 8 and distributed in a ring shape, the bottom of the movable shaft 1601 extends into the storage tank 2, a plurality of rotating blocks 1602 distributed at equal intervals are installed on the movable shaft 1601, and a plurality of stirring rods 1603 distributed in a ring shape are installed on the outer wall of the rotating block 1602.

[0043] In one case of this embodiment, the transmission component 17 includes a gear 1701 installed on the top of the movable shaft 1601 , and an inner gear ring 1702 meshing with the gear 1701 is installed on the inner wall of the support platform 4 .

[0044] During the rotation of the rotating disk 8, the meshing of the gear 1701 and the inner ring 1702 will drive the gear 1701 to rotate, thereby driving the movable shaft 1601 to rotate, and then driving the stirring rod 1603 on the rotating block 1602 to rotate, so that the grain in the storage tank 2 can be stirred, facilitating the contact between air and grain while preventing the grain from clumping.

[0045] In one case of this embodiment, the control component 24 includes a rotary encoder 2401 installed on the rotating shaft 11, which is used to calculate the number of rotations of the rotating disk 8. The bottom of the rotating disk 8 is equipped with a plurality of mounting frames 2402 distributed in a ring shape and corresponding to the return material baffle 22. An inner cavity 2403 is opened in the mounting frame 2402, and a slide plate 2404 is slidably arranged in the inner cavity 2403. A second telescopic member 2407 connected to the slide plate 2404 is installed in the inner cavity 2403. Preferably, the second telescopic member 2407 is configured as a hydraulic rod. The slide plate 2404 is fixedly connected to the first connecting rod 2405. One end of the first connecting rod 2405 away from the slide plate 2404 is hinged to one end of the second connecting rod 2406, and the other end of the second connecting rod 2406 is hinged to the return material baffle 22.

[0046] In order to prevent the grain accumulated on the return baffle 22 from affecting the air intake effect of the second ventilation hole 9, the number of revolutions of the rotating disk 8 will be detected by the rotary encoder 2401 during the rotation of the rotating disk 8. When the rotating disk 8 rotates a certain number of times, the external controller will control the second hydraulic rod to start, so that the second hydraulic rod will contract, driving the slide plate 2404 to move, and cooperating with the first connecting rod 2405 and the second connecting rod 2406, the return baffle 22 can be driven to rotate downward, thereby opening the return port 21, so that the grain on the return baffle 22 will fall back into the storage tank 2, and then the second hydraulic rod will be reset, so that the return baffle 22 will re-block the return port 21, and cooperating with the feeding component, the circulating ventilation and heat dissipation of the grain in the storage tank 2 can be realized, and the use effect is better.

[0047] In one case of the present embodiment, the top outer wall of the ventilation duct 13 is provided with a plurality of air collecting blocks 26 distributed in a ring-shaped interval, the air collecting blocks 26 are connected to the air guide port 25, the air collecting blocks 26 are fixedly connected to the air guide pipe 27, the air guide pipe 27 is rotatably connected to the top of the movable shaft 1601, the movable shaft 1601 is hollow, and the outer wall of the movable shaft 1601 is provided with a plurality of air outlets 28 distributed in a ring-shaped interval.

[0048] When the fan 19 generates suction force and draws in external air from the second ventilation hole 9, the air flow will flow upward from the bottom of the fan 19, and will enter the air collecting block 26 from the air guide port 25 at the top of the ventilation tube 13, and will be transported to the movable shaft 1601 through the air guide pipe 27, and enter the interior of the storage tank 2 through the air outlet 28. The stirring component 16 can stir the grain to allow air to enter the stacked grain, thereby effectively ventilating and dissipating the heat of the grain, and as the movable shaft 1601 rotates, the position of the air outlet 28 will also change, resulting in a better effect.

[0049] In one case of this embodiment, a top cover 29 is installed on the top of the support platform 4, and the top of the top cover 29 is conical. The outer wall of the top cover 29 is installed with multiple solar panels 30 distributed in a ring-shaped manner. The solar panels 30 on the top of the top cover 29 generate electrical energy and supply power to the power equipment in the present invention.

[0050] The present invention can continuously transport the grain at the bottom of the storage tank 2 to the rotating disk 8 at a high position through the action of the feeding pipe 6 and the feeding component, thereby preventing the grain at the bottom of the storage tank 2 from being squeezed for a long time and causing poor ventilation and mold. The centrifugal force generated by the rotating rotating disk 8 will continuously roll the grain transported to the rotating disk 8 toward the outside of the rotating disk 8 until the grain moves into the return baffle 22. In this process, the rolling grain can be fully ventilated and cooled by the flowing air, thereby preventing the problem of heat accumulation and mold caused by insufficient internal ventilation of the grain due to the accumulation of grain. When too much grain is accumulated on the return baffle 22, in order to prevent the accumulated grain from affecting the air intake effect of the second ventilation hole 9, the control component 24 will open the return baffle 22 to discharge the accumulated grain, thereby realizing the circulation, ventilation and heat dissipation of the grain in the storage tank 2. In addition, during the rotation of the rotating disk 8, the grain in the storage tank 2 will be stirred by the stirring component 16, which facilitates the contact between air and grain while also preventing the grain from agglomerating.
