Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, specifically to a cooling device for storing agricultural products. Background Technology

[0002] Agricultural products are generally stored in large warehouses, where they are centrally stacked. For example, grains or rice grains are still active during storage and will produce moisture through respiration. This requires storage equipment used for long-term storage to have good ventilation, drying, moisture-proof and damp-proof functions.

[0003] In existing technologies, ventilation equipment in warehouses only ventilates the outside air of the grain. While this ensures the dryness and humidity inside the warehouse, the grain is typically piled very high to maximize warehouse space. This makes it difficult for the grain pile to ventilate effectively on its own. Over time, moisture accumulates inside the grain pile, causing internal heating, bacterial growth, and mold, resulting in significant crop losses. Therefore, this solution provides a cooling device for agricultural product storage to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a cooling device for agricultural product storage is provided. This technical solution solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cooling device for agricultural product storage includes a storage silo, which includes a silo body. A heat dissipation vent is fixedly installed on the upper right side of the silo body. An installation groove is opened at the bottom of the silo body. An air supply mechanism, a cooling mechanism, and a filtration mechanism are installed inside the installation groove. A base plate is fixedly connected to the silo body. A fixed cylinder is fixedly installed on the base plate. The fixed cylinder includes a cylinder body. A conveying mechanism is installed inside the cylinder body. Four sets of air slots connected to the air supply mechanism are opened on the cylinder body. Several sets of crossbars are fixedly connected between the cylinder body and the silo body. Each crossbar has an opening at its bottom. An air outlet pipe connected to the air slot is fixedly installed inside each opening.

[0007] Preferably, the bottom of the cylinder has a feed inlet and the top of the cylinder has a discharge outlet, and a hopper is fixedly installed inside the discharge outlet.

[0008] Preferably, the air supply mechanism includes a fan fixedly installed in the installation slot, a diversion pipe fixedly installed at the top of the cylinder, the lower end of the diversion pipe being connected to four sets of air slots respectively, a second heat insulation pipe fixedly installed at the inlet of the fan, one end of the second heat insulation pipe being connected to the cooling mechanism, and a first heat insulation pipe fixedly installed at the outlet of the fan, the upper end of the first heat insulation pipe being connected to the diversion pipe.

[0009] Preferably, the cooling mechanism includes a bent pipe connected to the second insulation pipe, a cooling tank for holding coolant is provided on the outside of the bent pipe, the cooling tank is fixedly installed inside the mounting groove, a cooler is fixedly installed at the bottom of the cooling tank, and a third insulation pipe is fixedly installed at one end of the bent pipe, and one end of the third insulation pipe is connected to the filter mechanism.

[0010] Preferably, the filtration mechanism includes a filter box that is connected to the insulation pipe. The filter box is fixedly installed inside the mounting groove. Two sets of mounting brackets are slidably installed on the upper end of the filter box. Filter screens and breathable silicone plates are fixedly installed inside the two sets of mounting brackets respectively. Pressure plates are rotatably installed on both sides of the upper end of the filter box. Locking rods are provided on the pressure plates. The lower end of the locking rods passes through the pressure plates and is threadedly connected to the upper end of the filter box.

[0011] Preferably, an intercepting net is fixedly installed at the bottom of the opening, and several sets of air outlet holes are opened at the lower end of the air outlet pipe.

[0012] Preferably, the conveying mechanism includes a rotating shaft rotatably installed inside the cylinder, a servo motor fixedly installed in the mounting groove on the lower side of the rotating shaft, the output shaft of the servo motor being fixedly connected to the lower end of the rotating shaft, and conveying blades being fixedly connected to the rotating shaft.

[0013] Compared with the prior art, this utility model proposes a cooling device for agricultural product storage, which has the following beneficial effects:

[0014] 1. The mounting slot of this utility model is equipped with an air supply mechanism, a cooling mechanism, and a filtration mechanism. By activating the air supply mechanism, the fan in the air supply mechanism can draw in outside air. The outside air then passes through the filtration mechanism and the cooling mechanism. The filter screen and the breathable silicon plate in the filtration mechanism can remove dust and dehumidify the air. Subsequently, the filtered air is cooled in the curved pipe in the cooling mechanism. Finally, through the cooperation of the fan, the first insulation pipe, the second insulation pipe, and the diversion pipe, the cooled air enters the air slot and is finally discharged through the air outlet of the air outlet pipe. This allows the dry and cold air to re-enter the accumulated rice grains and diffuse through the gaps between the rice grains, thereby cooling the grain from the inside. Finally, the air is discharged from the heat dissipation vent at the top.

[0015] 2. This utility model includes a conveying mechanism. By activating the servo motor in the conveying mechanism, the servo motor drives the conveying blades through the rotating shaft. This, in conjunction with the inlet and outlet of the fixed cylinder, allows the conveying blades to transport and circulate the grain from bottom to top. Combined with the hopper fixed at the outlet, the grain can be thrown outwards from the top, ensuring sufficient contact with cold air during its descent. Simultaneously, the rice is in a flowing state during transport, increasing the gaps between grains and allowing cold air to escape. This further improves overall ventilation and heat dissipation, solving the problem of poor ventilation and heat dissipation when rice is piled up during storage. Attached Figure Description

[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0033] Reference Figure 1-7 As shown, a cooling device for agricultural product storage includes a storage silo 1, which includes a silo body 101. A heat dissipation vent 103 is fixedly installed on the upper right side of the silo body 101. An installation groove 102 is provided at the bottom of the silo body 101. An air supply mechanism 6, a cooling mechanism 7, and a filter mechanism 8 are provided inside the installation groove 102. A bottom plate 2 is fixedly connected inside the silo body 101. A fixed cylinder 3 is fixedly installed on the bottom plate 2. The fixed cylinder 3 includes a cylinder body 301. A conveying mechanism 5 is provided inside the cylinder body 301. Four sets of air slots 305 connected to the air supply mechanism 6 are provided on the cylinder body 301. Several sets of crossbeams 4 are fixedly connected between the cylinder body 301 and the silo body 101. An opening 401 is provided at the bottom of each crossbeam 4. An air outlet pipe 402 connected to the air slot 305 is fixedly installed inside each opening 401.

[0034] Furthermore, this device is equipped with an air supply mechanism 6, a cooling mechanism 7, and a filtration mechanism 8. By activating the fan 601 in the air supply mechanism 6, the fan 601 can draw in outside air. The outside air then passes through the filtration mechanism 8 and the cooling mechanism 7. The filter screen 803 and the breathable silicon plate 804 in the filtration mechanism 8 can remove dust and dehumidify the air. Subsequently, the filtered air is cooled in the cooling mechanism 7. Finally, through the cooperation of the fan 601, the first insulation pipe 602, the second insulation pipe 604, and the diversion pipe 603, the cooled air enters the air tank 305 and is finally discharged through the air outlet of the air outlet pipe 402. This allows the dry and cold air to re-enter the accumulated rice grains and diffuse through the gaps between the rice grains, thereby cooling the grain from the inside. Finally, it is discharged from the heat dissipation vent 103 at the top.

[0035] Specifically, in this embodiment, the bottom of the cylinder 301 is provided with a feed inlet 302, the top of the cylinder 301 is provided with a discharge outlet 303, and a hopper 304 is fixedly installed inside the discharge outlet 303.

[0036] Specifically, in this embodiment, the air supply mechanism 6 includes a fan 601 fixedly installed in the mounting groove 102, a diversion pipe 603 fixedly installed at the top of the cylinder 301, the lower end of the diversion pipe 603 being connected to four sets of air slots 305 respectively, a second heat insulation pipe 604 fixedly installed at the inlet of the fan 601, one end of the second heat insulation pipe 604 being connected to the cooling mechanism 7, and a first heat insulation pipe 602 fixedly installed at the outlet of the fan 601, the upper end of the first heat insulation pipe 602 being connected to the diversion pipe 603.

[0037] Furthermore: By activating the fan 601 in the air supply mechanism 6, the fan 601 can draw in outside air. The outside air then undergoes dust removal, drying, and cooling treatment through the filter mechanism 8 and the cooling mechanism 7. The treated air, through the cooperation of the insulation pipe 1 602, insulation pipe 2 604, and the diversion pipe 603, allows the cooled air to enter the air trough 305 and finally exit through the air outlet of the air outlet pipe 402. This allows the dry and cold air to re-enter the accumulated rice grains and diffuse through the gaps between the rice grains, thereby cooling the grain from the inside and finally discharging it from the heat dissipation vent 103 at the top.

[0038] Specifically, in this embodiment, the cooling mechanism 7 includes a bent pipe 703 connected to the second insulation pipe 604. A cooling tank 701 for holding coolant is provided on the outside of the bent pipe 703. The cooling tank 701 is fixedly installed inside the mounting groove 102. A cooler 702 is fixedly installed at the bottom of the cooling tank 701. A third insulation pipe 704 is fixedly installed at one end of the bent pipe 703. One end of the third insulation pipe 704 is connected to the filter mechanism 8.

[0039] Furthermore: The cooling tank 701 in the cooling mechanism 7 is used to hold coolant. Through the operation of the refrigerator 702, the coolant enters a low temperature state, and the bent pipe 703 is immersed in the coolant, so that the temperature of the bent pipe 703 is consistently lower than that of the outside air. When the gas flows in the bent pipe 703, the air will exchange heat with the bent pipe 703, thereby reducing the temperature of the air. Finally, the low temperature air is delivered to the air tank 305 by the fan 601.

[0040] Specifically, in this embodiment, the filtration mechanism 8 includes a filter box 801 connected to the insulation pipe 704. The filter box 801 is fixedly installed inside the mounting groove 102. Two sets of mounting brackets 802 are slidably installed on the upper end of the filter box 801. Filter screens 803 and breathable silicon plates 804 are fixedly installed inside the two sets of mounting brackets 802 respectively. Pressure plates 805 are rotatably installed on both sides of the upper end of the filter box 801. Locking rods 806 are provided on the pressure plates 805. The lower end of the locking rods 806 passes through the pressure plates 805 and is threadedly connected to the upper end of the filter box 801.

[0041] Furthermore: When the fan 601 can draw in outside air, the air can be dusted and dehumidified by the filter screen 803 and the breathable silicone plate 804 in the filter mechanism 8. After a period of use, the filter screen 803 and the breathable silicone plate 804 need to be replaced. By rotating the locking rod 806, the pressure plate 805 can be released from fixing the mounting bracket 802, and the two sets of mounting brackets 802 can be pulled out from the filter box 801 to facilitate cleaning of the filter screen 803 and the breathable silicone plate 804.

[0042] Specifically, in this embodiment, an intercepting net 403 is fixedly installed at the bottom of the opening 401, and several sets of air outlet holes are opened at the lower end of the air outlet pipe 402.

[0043] Furthermore, the opening 401 at the lower end of the cross frame 4 facilitates the escape of cold air from the vent pipe 402, while preventing the grain on the outside from blocking the vent hole of the vent pipe 402. The intercepting net 403 inside the opening 401 further ensures the usability of the vent pipe 402.

[0044] Specifically, in this embodiment, the conveying mechanism 5 includes a rotating shaft 502 rotatably installed inside the cylinder 301. A servo motor 501 is fixedly installed in the mounting groove 102 on the lower side of the rotating shaft 502. The output shaft of the servo motor 501 is fixedly connected to the lower end of the rotating shaft 502. A conveying blade 503 is fixedly connected to the rotating shaft 502.

[0045] Furthermore, by activating the servo motor 501 in the conveying mechanism 5, the servo motor 501 drives the conveying blades 503 via the rotating shaft 502. This, in conjunction with the inlet 302 and outlet 303 of the cylinder 301, allows the conveying blades 503 to transport and circulate the grain from bottom to top. Combined with the hopper 304 fixed at the outlet 303, the grain can be scattered outwards from the top, ensuring sufficient contact with cold air during its descent. Simultaneously, the rice remains in a flowing state during transport, increasing the gaps between grains and allowing cold air to escape. This further improves overall ventilation and heat dissipation, solving the problem of poor ventilation and heat dissipation when rice is piled up during storage.

[0046] The working principle of this utility model is as follows: After the grains are piled up for a period of time, the air supply mechanism 6, the cooling mechanism 7 and the conveying mechanism 5 are activated. The air supply mechanism 6 is equipped with a fan 601. By activating the fan 601, the fan 601 can draw in outside air. The outside air then passes through the filtration mechanism 8 and the cooling mechanism 7. The filter screen 803 and the breathable silicon plate 804 in the filtration mechanism 8 can remove dust and dehumidify the air. Subsequently, the filtered air is cooled in the cooling mechanism 7, and finally, through the cooperation of the insulation pipe 1 602, the insulation pipe 2 604 and the diversion pipe 603, the cooled air enters the air trough 305 and is finally discharged through the air outlet of the air outlet pipe 402. This allows the dry and cold air to enter the piled rice grains and diffuse through the gaps between the rice grains, thereby cooling the grains from the inside, and finally being discharged from the heat dissipation vent 103 at the top.

[0047] Simultaneously, the servo motor 501 in the conveying mechanism 5 starts, and the servo motor 501 then drives the conveying blades 503 through the rotating shaft 502. This, in conjunction with the inlet 302 and outlet 303 of the cylinder 301, allows the conveying blades 503 to transport and circulate the grain from bottom to top. In conjunction with the hopper 304 fixed at the outlet 303, the grain can be scattered outward from the top, allowing the grain to fully contact the cold air during its descent. At the same time, during the transport process, the rice is in a flowing state, which increases the gaps between them, thereby ensuring the escape of cold air and further improving the overall ventilation and heat dissipation effect. This solves the problem of poor ventilation and heat dissipation when rice is piled up during storage.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
