[0002] Wheat is an annual or biennial herbaceous plant belonging to the Poaceae family and the Triticum genus. The culms are erect, tufted, with loosely sheathed leaf blades that enclose the stem. The ligule is membranous, and the leaf blades are long and lanceolate. The spike-like inflorescence is erect, with spikelets containing numerous florets. The glumes are ovate, the lemma is oblong-lanceolate, and the palea is nearly equal in length to the lemma. It is widely cultivated in various regions, with many varieties exhibiting different characteristics.

A gas mixing tank 8 is installed on the right side of the support frame 2 via a fixing plate. An air inlet ring 9 is fixedly installed inside the preservation tank 1. A filter screen 21 is fixedly connected inside the air inlet ring 9. The filter screen 21 protects the air outlet of the air inlet ring 9, preventing wheat seeds from entering the air outlet and causing blockage. The output of the flow meter 7 is connected to the bottom of the gas mixing tank 8 via a connecting pipe. The top of the gas mixing tank 8 is connected to the surface of the air inlet ring 9 via a connecting pipe. A one-way exhaust valve 10 is connected to the top of the rear side of the storage tank 1.

An air filter 20 is fixedly installed on the rear side of the inner wall of the storage tank 1. The air filter 20 is located in front of the one-way exhaust valve 10. The air filter 20 protects the one-way exhaust valve 10 and can prevent the one-way exhaust valve 10 from becoming blocked and affecting the exhaust efficiency. An observation spotlight 22 is fixedly installed on the top of the storage tank 1. By turning on the observation spotlight 22 to illuminate the top of the storage tank 1, the user can observe the wheat seeds inside the storage tank 1 through the polycarbonate top cover.

[0032] Reference Figure 1-3 A stirring assembly is fixedly installed on the top of the storage tank 1. The stirring assembly includes a transmission device 11, which includes a mounting frame, a transmission motor, and a reducer. The transmission device 11 is fixedly installed on the top of the storage tank 1. A planar magnetic coupling 12 is fixedly installed at the output end of the transmission device 11. The bottom of the planar magnetic coupling 12 is located inside the storage tank 1. A spiral conveying rod 13 is fixedly installed at the bottom of the planar magnetic coupling 12. A sleeve 14 is fitted onto the surface of the spiral conveying rod 13. The surface of the sleeve 14 is fixedly connected to... A fixed plate assembly 15 is attached, with its surface fixedly connected to the inner wall of the storage tank 1. A wind sleeve 16 is movably connected to the surface of the spiral conveying rod 13, and a connecting plate 17 is fixedly connected to the bottom of the wind sleeve 16. The bottom of the connecting plate 17 is fixedly connected to the fixed plate assembly 15. Through the cooperation of the transmission device 11, the planar magnetic coupling 12, the spiral conveying rod 13, the sleeve 14, and the fixed plate assembly 15, the wheat inside the storage tank 1 can be conveyed to solve the problem of uniformity of the wheat environment inside the storage tank 1.

[0033] Reference Figure 2-5The air jacket 16 has an internal air guiding assembly, which includes a fan blade 18 fixedly mounted on the top of the surface of the spiral conveyor rod 13. Air ducts 19 connect to both sides of the air jacket 16. A one-way valve is installed at the bottom of each air duct 19, located inside the air inlet ring 9. The bottom of the air duct 19 connects to the top of the air inlet ring 9, and the surface of the air duct 19 is fixedly connected to the inner wall of the storage tank 1. A temperature and humidity sensor 23 is fixedly mounted on the top of the inner wall of the storage tank 1. Through the cooperation of the fan blade 18 and the air duct 19, the gas at the top of the inner cavity of the storage tank 1 is transported to the interior of the air inlet ring 9 for recirculation, ensuring sufficient contact between the gas and the wheat seeds.

[0034] Working Principle: After the user places wheat seeds into storage tank 1, they open solenoid valve 6 and transmission device 11. Upon opening solenoid valve 6, nitrogen and carbon dioxide gases from nitrogen tank 4 and carbon dioxide tank 5 enter the gas mixing tank 8 through flow meter 7 and connecting pipe for mixing. The mixed gas then enters the intake ring 9 through the connecting pipe, which in turn delivers the mixed gas into storage tank 1. As storage tank 1 receives the mixed gas, its internal pressure increases. Oxygen is discharged through air filter 20 and one-way exhaust valve 10, maintaining a slightly positive pressure environment in storage tank 1. During continuous gas delivery, the pressure in storage tank 1... The interior becomes a low-oxygen environment, which slows down seed oxidation and increases preservation time. The output end of the transmission device 11 drives the planar magnetic coupling 12 to rotate. The planar magnetic coupling 12 drives the spiral conveyor rod 13 and the fan blade 18 to rotate. The spiral conveyor rod 13 conveys the wheat seeds at the bottom of the inner cavity of the preservation tank 1 upward to prevent the wheat seeds from accumulating and generating heat. At the same time, it can make the mixed gas diffuse evenly and prevent the problem of gas accumulation dead zones. The rotation of the fan blade 18 inside the air sleeve 16 can convey the gas at the top of the inner cavity of the preservation tank 1 to the air duct 19 and the air inlet ring 9, so that the gas is ejected again through the air inlet ring 9, improving the gas diffusion effect.
