Description

Technical Field

[0001] This invention relates to the field of seed storage technology, specifically to a corn seed storage device and its usage method. Background Technology

[0002] Corn seed storage devices are specialized equipment or facilities used to maintain the viability of corn seeds, extend their shelf life, and ensure seed quality. Their core purpose is to prevent seed viability decline during storage due to factors such as moisture, mold, pests, or abnormal temperatures through appropriate temperature and humidity control and ventilation management. This ensures high varietal and sowing quality, meeting the quantity and quality requirements of agricultural production. Corn seed storage devices are specialized equipment or spaces used to store corn seeds, designed to protect seed quality and extend storage life. Commonly used corn seed storage devices include storage bags, storage boxes, sealed containers, storage rooms, and cold storage facilities. However, current storage devices for corn seeds have limited storage space due to their fixed-volume chambers. This makes them unsuitable for storing large quantities of seeds, while they are incomplete for smaller batches, resulting in poor practicality. Furthermore, current storage devices are all integral structures, with the ventilation, heating, and other electrical components fixed to the device. This necessitates comprehensive maintenance, requiring the disassembly of individual bolts, which is time-consuming and labor-intensive.

[0021] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 The connecting component 4 includes a fixed frame 401. Two sets of fixed frames 401 are located on opposite outer walls of the mounting frame 1. The fixed frames 401 are connected by a plug-in connection. An upper guide shell 402 is embedded in the inner cavity of the fixed frame 401, located on the top outer wall of the storage tank 2. A limit groove 403 is formed on the outer wall of the upper guide shell 402. An upper sealing cover 404 is hinged to the outer wall of the upper guide shell 402. A magnetic adsorption block 405 is embedded in the side wall of the upper sealing cover 404. A strong magnetic fixing block 406 is embedded at the port of the upper guide shell 402. The strong magnetic fixing block 406 and the magnetic adsorption block 405 are connected by a magnetic connection. A lower guide shell 407 is embedded in the inner cavity of the fixed frame 401, located on the bottom outer wall of the storage tank 2. A lower sealing cover plate 408 is hinged to the outer wall of the lower guide shell 407. A magnetic adsorption block 409 is embedded in the side wall of the lower sealing cover plate 408. A strong magnetic positioning block 410 is embedded in the port of the lower guide shell 407. The strong magnetic positioning block 410 and the magnetic adsorption block 409 are connected by magnetic connection. A lower guide block 411 is installed on the inner wall of the lower guide shell 407. The bottom end of the lower guide block 411 is lower than the bottom end of the lower guide shell 407. The lower guide block 411 and the limiting slide groove 403 are connected by sliding connection. The upper guide shell 402 is located in the inner cavity of the lower guide shell 407 and is connected by plug-in connection. The top end of the upper guide shell 402 is higher than the top end of the lower guide shell 407. The upper sealing cover plate 404 and the lower sealing cover plate 408 are both located in the inner cavity of the storage tank 2.

[0022] Based on the aforementioned structural features and connection relationships, the circulating fan 316 and heater 317 are disconnected from the connection interface 302. Subsequently, only the new circulating housing 315 needs to be inserted into the circulating adjustment assembly 3 for fixation, so as to facilitate timely replacement and maintenance of damaged electrical equipment. Using a modular electrical structure, the control panel 318 has a sensing structure, and the sensor of the sensing structure of the control panel 318 extends into the inner cavity of the storage tank 2. The sensor of the control panel 318 detects the humidity of the inner cavity of the storage tank 2 in real time. When the set parameters are reached, the control panel 318 will control the circulating fan 316 and heater 317 to operate. The heater 317 heats the gas, and the circulating fan 316 generates a circulating airflow, which in turn carries the moisture out of the inner cavity of the storage tank 2.

[0023] Based on the aforementioned structural features and connection relationships, when the device is stored, the stacked devices are pulled out one by one to disconnect the connection component 4 of the storage tank 2. Then, the position of the storage tank 2 is simply reversed so that the storage tank 2 is upside down. Under the action of gravity, the lower sealing cover 408 and the upper sealing cover 404 will rotate respectively, thereby causing the strong magnetic fixing block 406 to magnetically attract and fix the magnetic adsorption block 1 405, so that the magnetic adsorption block 1 405 fixes the upper sealing cover 404. At the same time, the strong magnetic positioning block 410 magnetically attracts and fixes the magnetic adsorption block 2 409, so that the magnetic adsorption block 2 409 fixes the lower sealing cover 408.

[0024] The control panel 318 is connected to the electrically controlled discharge valve 9, drive motor 306, circulating fan 316 and heater 317 via wires. This connection enables the device to be powered on, thereby allowing the control panel 318 to control the operation of the electrically controlled discharge valve 9, drive motor 306, circulating fan 316 and heater 317.

[0025] In operation, the corn seed storage device and its usage method involve inserting and unplugging the connecting components 4 of the two sets of storage tanks 2 to fix the fixing frames 401 together. This causes the upper guide shell 402 to move upward and insert into the inner wall of the lower guide shell 407, resulting in the top end of the upper guide shell 402 moving out to one end of the top of the lower guide shell 407. This then applies a pushing force to the lower sealing cover 408, causing the lower sealing cover 408 to rotate on the outer wall of the hinge. This, in turn, causes the lower sealing cover 408 to move the magnetic adsorption block 409, disconnecting it from the strong magnetic positioning block 410. Simultaneously, the lower guide shell 407 moves downward relative to the upper guide shell 402, causing the lower guide block 411 to move downward as well. As block 411 slides down the inner wall of the limiting groove 403, the bottom end of the lower guide block 411 applies a pushing force to the upper sealing cover 404, causing the upper sealing cover 404 to rotate on the outer wall of the hinge. This causes the upper sealing cover 404 to move the magnetic adsorption block 405, disconnecting the magnetic adsorption block 405 from the strong magnetic fixing block 406. Since the lower guide housing 407 is inserted into the upper guide housing 402, and the lower sealing cover 408 and the upper sealing cover 404 are opened by the pushing force, the inner cavities of the upper and lower storage tanks 2 are connected. This device can be assembled by selecting an appropriate number of devices according to the actual seed storage needs, thereby solving the problem that the storage space is not large enough when dealing with a large quantity of corn seeds, and the storage space is not full when dealing with a small batch of corn seeds, resulting in poor practicality of the storage device.

[0026] By turning on the switch of the control panel 318, the control panel 318 controls the drive motor 306 to operate, which in turn causes the drive shaft of the drive motor 306 to drive the double-ended reverse threaded rod 305 to rotate. When the double-ended reverse threaded rod 305 drives the sliding base 313 through the threaded connection, the sliding base 313 moves laterally on the inner wall of the fixed housing 304. Since the threads at both ends of the double-ended reverse threaded rod 305 are in opposite directions, the sliding bases 313 on both sides of the double-ended reverse threaded rod 305 move in opposite directions, which in turn causes the sliding bases 313 to drive the pushing cone 314 to move to both sides, causing the pushing cone 314 to move relative to the sides. When the limiting guide block 311 is removed, it loses the squeezing force of the pushing cone block 314. At this time, the stretched limiting spring 310 resets, which in turn applies a pulling force to the insertion and removal fixing block 309. This causes the insertion and removal fixing block 309 to move the limiting guide rod 308. At the same time, the insertion and removal fixing block 309 drives the limiting guide block 311 to reset, which causes the insertion and removal fixing block 309 to move out of the connecting groove 319. This allows the circulation shell 315 to be disassembled without being fixed, thus solving the problem that the electrical structures such as ventilation and heating of the storage device are fixed on the device, and maintenance requires disassembling the fixing bolts one by one, which is time-consuming and laborious.

[0027] By starting the drive motor 306 via the control panel 318, a series of mechanical transmissions eventually disengage the plug-in fixing block 309 from the connecting slot 319, thereby disassembling the circulation housing 315. Then, simply pulling off the circulation housing 315 will cause it to move the circulation fan 316 and heater 317 outwards, disconnecting the circulation fan 316, heater 317, and connecting interface 302. A new circulation housing 315 can then be inserted into the circulation adjustment assembly 3 for fixation, facilitating timely replacement and maintenance of damaged electrical equipment. The modular electrical structure design prevents seeds inside the storage tank 2 from germinating due to prolonged maintenance time, thus solving the problem of seeds germinating due to moisture when the electrical structure is damaged and requires overall maintenance of the storage device. Because the electrical structure cannot be replaced in time, the device's function cannot be properly maintained, leading to seeds germinating due to moisture inside the storage device.

The method of using the corn seed storage device according to claim 9, wherein the steps are as follows: Operation Step 1: By inserting and unplugging the connecting components (4) of the two sets of storage tanks (2), the fixing frames (401) are connected and fixed by insertion and unplugging, thereby causing the upper guide shell (402) to move up and insert into the inner wall of the lower guide shell (407), causing the top of the upper guide shell (402) to move out to one end of the top of the lower guide shell (407), and then one end of the upper guide shell (402) applies a pushing force to the lower sealing cover (408), causing the lower sealing cover (408) to rotate on the outer wall of the hinge, thereby causing the lower sealing cover (408) to drive the magnetic adsorption block two (409) to move, and causing the magnetic adsorption block two (409) and the strong magnetic positioning block (410) to disconnect; Operation Step 2: Simultaneously, as the lower guide shell (407) moves downward relative to the upper guide shell (402), the lower guide shell (407) will drive the lower guide block (411) to move downward. The lower guide block (411) slides down on the inner wall of the limiting slide groove (403), which will cause the bottom end of the lower guide block (411) to apply a pushing force to the upper sealing cover plate (404), thereby causing the upper sealing cover plate (404) to rotate on the outer wall of the hinge, thereby causing the upper sealing cover plate (404) to drive the magnetic adsorption block one (405) to move, which will cause the magnetic adsorption block one (405) and the strong magnetic fixing block (406) to disconnect. As the lower guide shell (407) is inserted into the upper guide shell (402), the lower sealing cover plate (408) and the upper sealing cover plate (404) are opened by the pushing force, thereby making the inner cavities of the upper and lower storage tanks (2) connected. Operation Step 3: By turning on the switch of the control panel (318), the control panel (318) controls the drive motor (306) to run, thereby causing the drive shaft of the drive motor (306) to drive the double-ended reverse thread rod (305) to rotate. When the double-ended reverse thread rod (305) drives the sliding base (313) through the threaded connection, the sliding base (313) moves laterally on the inner wall of the fixed housing (304). Since the threads at both ends of the double-ended reverse thread rod (305) are opposite, the sliding bases (313) on both sides of the double-ended reverse thread rod (305) will move in opposite directions respectively. Operation Step 4: The sliding base (313) then drives the pushing cone (314) to move to both sides, causing the pushing cone (314) to move away from the limiting guide block (311). The limiting guide block (311) loses the squeezing force of the pushing cone (314). At this time, the stretched limiting spring (310) resets, causing the limiting spring (310) to apply a pulling force to the plug-in fixing block (309), causing the plug-in fixing block (309) to drive the limiting guide rod (308) to move. At the same time, the plug-in fixing block (309) drives the limiting guide block (311) to reset, causing the plug-in fixing block (309) to move out of the connecting groove (319), thereby disassembling the circulating housing (315). Operation Step 5: Start the drive motor (306) through the control panel (318). Through a series of mechanical transmissions, the plug-in fixing block (309) will eventually disengage from the connecting slot (319), thereby disassembling the circulation housing (315). Then, simply pull out the circulation housing (315), which will cause the circulation housing (315) to drive the circulation fan (316) and heater (317) to move outward, thereby disconnecting the circulation fan (316), heater (317) and connecting interface (302). Then, simply insert the new circulation housing (315) into the circulation adjustment assembly (3) for replacement and maintenance.
