[0002] Low-temperature long-term grain storage is to keep the temperature of the grain pile below 15℃ (low temperature) or 20℃ (quasi-low temperature) for a long time. Low-temperature storage of grain is an internationally recognized scientific and pollution-free grain storage method. In order to facilitate the refrigeration of the granary, a corresponding grain cooler is usually used to circulate air to cool the interior of the granary.

[0004] Among them, the above-mentioned prior art has the following technical problems: when the existing grain cooler is in use, in order to facilitate the heat inside the body to be dissipated to the outside, a cooling fan is arranged on the top of the body. When a single cooling fan discharges the heat to the outside, the overall heat dissipation effect is poor. When a lot of heat accumulates inside the body, it is easy for the heat to accumulate inside the body due to untimely heat dissipation. At the same time, when the body is in use, the dust outside is blocked by the dustproof net on the outside of the cooling fan.

DETAILED DESCRIPTION

[0041] 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.

When a single cooling fan discharges the heat to the outside, the overall heat dissipation effect is poor. When the heat inside the machine body is pushed more, it is easy to cause the heat to accumulate inside the machine body due to untimely heat dissipation. In order to solve this technical problem, this embodiment discloses the following technical content;

The extraction component includes a connecting column 13, a guide column 131, an auxiliary spring 132, an air storage groove 133, a pressure block 134, an air suction pipe 135 and an air outlet pipe 136, and the connecting column 13 is fixed to the side of the center rod 12, the middle of the connecting column 13 is inserted with a guide column 131, and the guide column 131 extends into the air storage groove 133 inside the connecting column 13, and one end of the guide column 131 extending into the air storage groove 133 inside the connecting column 13 is connected to the connecting column 13 through the auxiliary spring 132 and the air storage groove 133. The air grooves 133 are connected to each other, and a pressure block 134 is provided on the side of one end of the guide column 131 extending out of the connecting column 13, and the pressure block 134 is fixed to the inner circumference of the heat dissipation cover 7. An air intake pipe 135 is fixedly connected to the side of the center rod 12, and an air outlet pipe 136 is provided above the connecting column 13. The end of the air outlet pipe 136 close to the connecting column 13 is connected to the inside of the center rod 12, and a one-way flow valve is installed on the air intake pipe 135 and the air outlet pipe 136. The air storage groove 133 inside the connecting column 13 is connected to the inside of the center rod 12, and the inside of the center rod 12 is set as a hollow structure, and the inside of the center rod 12 is connected to the air intake pipe 135 and the air outlet pipe 136. One end of the guide column 131 extending into the air storage groove 133 forms a seamless sliding connection structure with the air storage groove 133 through a circumferentially fixed sealing ring, and the end of the guide column 131 extending outside the air storage groove 133 and the pressure block 134 are both arranged in an arc shape, and there are multiple pressure blocks 134 evenly distributed at equal angles in the internal circumferential direction of the heat dissipation cover 7.

[0044] When in use, the air supply port 6 on the refrigeration box body 3 is connected to the air inlet pipe on the granary, and the return air port 5 on the refrigeration box body 3 is connected to the air outlet pipe on the granary. When the granary is cooled, the refrigeration box body 3 sends the cold air flow into the interior of the granary through the air supply port 6 to cool the grains. The air flow on the upper part of the granary enters the interior of the refrigeration box body 3 through the air outlet pipe and the return air port 5 to refrigerate the grains, thereby realizing circulating air cooling inside the granary. It should be noted here that the refrigeration principle inside the refrigeration box body 3 is the existing technology, and no improvement has been made to the refrigeration principle (for example, the specific refrigeration principle of the grain cooler is disclosed in the existing technology with publication number CN207351083U). When the refrigeration box body 3 is working, the servo motor 9 is turned on. After the servo motor 9 is turned on, the center rod 12 can drive the heat dissipation fan 11 to rotate. The rotation of the heat dissipation fan 11 can discharge the heat generated by the internal operation of the refrigeration box body 3 to the outside, and when the center rod 12 rotates, the side connecting column 13 and the guide column 131 can rotate synchronously. Here, the centrifugal force generated when the center rod 12 rotates will not cause the guide column 131 to expand and contract outward. When the guide column 131 rotates with the center rod 12 and contacts the pressure block 134 inside the heat dissipation cover 7, the pressure block 134 can be used to squeeze the guide column 131, so that the guide column 131 moves toward the inside of the connecting column 13. At this time, after the guide column 131 moves inside the air storage groove 133 inside the connecting column 13, the air storage groove 133 and the inside of the center rod 12 are connected to each other, thereby the center rod 12 can be connected to the center rod 12. The hot air flow inside the rod 12 is squeezed out and discharged through the air outlet pipe 136 thereon. When the guide column 131 rotates and disengages from the pressure block 134, the guide column 131 is reset and rebounded by the auxiliary spring 132. After the guide column 131 is reset, the center rod 12 can use the suction pipe 135 to absorb the heat flow inside the refrigeration box 3 again, which is convenient for the next extrusion and discharge. By rotating back and forth in this way, the heat dissipation effect inside the refrigeration box 3 can be improved through the rotation of the cooling fan 11 and the combination of exhaust and suction.

[0045] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. When the machine body is in use, the dust from the outside is blocked by the dustproof net 8 on the outside of the cooling fan 11. Since the grain cooler is a device that runs continuously outside for a long time, it is inevitable that a large amount of dust and impurities are easily attached to the dustproof net 8. The grain cooler is not convenient to automatically clean the dust attached to the dustproof net 8 while dissipating heat. When the dustproof net 8 is blocked by dust or impurities, the heat dissipation efficiency of the machine body is easily affected. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 3-Figure 9 As shown;

[0046] The exhaust component is connected to the vibration recoil component, and the vibration recoil component is used to clean the dust attached to the dustproof net 8. The vibration recoil component includes a moving column 14, a first magnetic block 141, a second magnetic block 142, a booster spring 143, a diverter plate 144, a jet head 145 and a vibration rod 146, and the moving column 14 is installed at the middle part of the upper end of the center rod 12, the lower end of the moving column 14 is connected to the middle part of the upper end of the center rod 12 through the booster spring 143, and the upper end side of the moving column 14 is fixedly connected with the first magnetic block 141, the second magnetic block 142 is arranged above the first magnetic block 141, and the second magnetic block 142 is fixed on the dustproof net 8 of the heat dissipation cover 7, the side of the moving column 14 is fixedly connected with the diverter plate 144, and the diverter plate 144 is connected to the outlet pipe 136, the upper end of the diverter plate 144 is fixedly connected with the jet head 145, and the vibration rod 146 is fixedly connected to the upper side of the diverter plate 144 close to the moving column 14. The moving column 14 forms an elastic telescopic structure through the assist spring 143 and the center rod 12, and the first magnetic block 141 on the upper side of the moving column 14 has the same magnetic properties as the second magnetic block 142, and multiple second magnetic blocks 142 are evenly distributed on the dustproof net 8. The interior of the diverter plate 144 is set as a hollow structure, and the diverter plate 144 and the jet head 145 are connected to each other, and the inner diameter of the jet head 145 gradually decreases from bottom to top. The vibration rod 146 and the diverter plate 144 are vertically distributed, and the upper end of the vibration rod 146 fits the dustproof net 8 in the initial state.

[0047] When the heat inside the center rod 12 is discharged to the outside through the air outlet pipe 136, the airflow can enter the inside of the diverter plate 144. After the airflow enters the inside of the diverter plate 144, the airflow inside it can be ejected outwardly through the nozzle 145. The airflow ejected outwardly through the nozzle 145 can recoil and clean the dust and impurities on the dust net 8. At the same time, when the center rod 12 rotates, it can make its moving column 14 and the diverter plate 144 rotate synchronously. The rotation of the diverter plate 144 can increase the cleaning range of the dust net 8 by the nozzle 145. At the same time, after the moving column 14 rotates, when the first magnetic block 141 on the upper end side of the moving column 14 and the second magnetic block 142 on the dust net 8 approach each other, the repulsive magnetic force generated by the second magnetic block 142 on the first magnetic block 141 can make the moving column 14 move downward. After moving downward, the diverter plate 144 and the vibration rod 146 can move downward synchronously. Since the air outlet pipe 136 is set to be made of rubber hose material, when the diverter plate 144 moves back and forth up and down, the shape of the air outlet pipe 136 itself will change. Therefore, the shape change of the air outlet pipe 136 is used to cooperate with the diverter plate 144 to move back and forth up and down. When the moving column 14 rotates with the center rod 12, the first magnetic block 141 on the upper end side and the second magnetic block 142 on the dustproof net 8 move away from each other, the moving column 14, the diverter plate 144 and the vibration rod 146 reset and rebound under the action of the booster spring 143. The vibration generated by the impact of the reset vibration rod 146 on the dustproof net 8 can reduce the adhesion of dust and impurities on the dustproof net 8, making it convenient for the ejected airflow to recoil and clean the dust and impurities.
