[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-6 A seed storage device includes a box body 1, with an opening reserved at the top of the box body 1. A box cover 3 is hingedly installed on the top of the box body 1 at the opening position through a hinge. A thermal insulation lining 2 is provided in the box body 1. The thermal insulation lining 2 reaches the four sides of the box body 1 and the bottom inner wall. The top of the thermal insulation lining 2 is at least three centimeters lower than the top of the box body 1. A thermal insulation pad 4 is installed on the side of the box cover 3 facing the box body 1 and corresponding to the position of the thermal insulation lining 2. A matching box cover lock 5 is installed on the front of the box body 1 and the box cover 3 through rivets.

[0030] A fan cover 8 is screwed to the left and rear position of the box body 1, and a fan 9 is installed in the fan cover 8. The fan 9 is set to blow air into the box body 1. The box body 1 and the thermal insulation lining 2 have openings corresponding to the position of the fan 9. The inner side of the thermal insulation lining 2 is provided with a shield 10 corresponding to the opening position of the fan 9. The shield 10 reaches the inner wall of the thermal insulation lining 2. The front and rear sides of the shield 10 are respectively provided with a sliding rod 11 and a screw rod 12. The front and rear sides of the shield 10 are respectively welded with a sliding sleeve 14 and a threaded sleeve 15. The sliding sleeve 14 is sleeved with the The sliding rod 11 is slidably sleeved, and the threaded sleeve 15 is sleeved on the screw rod 12 for threaded connection. The sliding rod 11 and the screw rod 12 are provided with shaft seats 13 at both ends. The shaft seats 13 are fixed to the box body 1 by screws passing through the thermal insulation lining 2. The two ends of the sliding rod 11 and the screw rod 12 are respectively sleeved on the shaft seats 13 at corresponding positions to form a sleeve fixation. The motor 16 is installed at the bottom end of the screw rod 12. The motor 16 is fixed to the box body 1 by screws passing through the thermal insulation lining 2. The shaft of the motor 16 and the screw rod 12 are connected by a pin key.

[0031] A shell 18 is installed with hot melt at the front left side of the box body 1. The shell 18 passes through the box body 1 and the thermal insulation lining 2. The cross-section of the shell 18 is an octagonal structure. A fan cover 20 is screwed on the left side of the shell 18. A fan 2 19 is installed in the fan cover 20. The fan 2 19 is set to blow air to the outside of the box body 1. A fan rack 25 is screwed on the right side of the shell 18. A fan 3 24 is installed on the fan rack 25. The fan 3 24 is set to blow air into the box body 1. A square frame 21 is screwed on the shell 18 between the fan rack 25 and the fan cover 20. The middle position inside the box 21 is hot melt installed. A partition 22 is installed, and a semiconductor refrigeration plate 23 is installed in the middle of the partition 22. The cold end of the semiconductor refrigeration plate 23 faces the inside of the box body 1, and the hot end faces the outside of the box body 1. The cross-section of the frame 21, the fan cover 20 and the fan rack 25 are all arranged in a quadrilateral structure. The four corners of the frame 21, the fan cover 20 and the fan rack 25 are staggered. A temperature and humidity sensor 26 is installed on the left inner wall of the thermal insulation lining 2, and an industrial control all-in-one computer 27 is installed on the front outside of the box body 1. The industrial control all-in-one computer 27 is electrically connected to the temperature and humidity sensor 26, fan 1 9, fan 2 19, fan 3 24 and the semiconductor refrigeration plate 23.

[0032] When in use, the seeds to be stored are placed in the thermal insulation lining 2 of the box body 1, and then the box cover 3 is closed. The storage temperature and humidity are set from the position of the industrial control integrated computer 27. First, the thermal insulation lining 2 is relied upon to provide a relatively stable maintenance environment for the seeds. At the same time, the temperature and humidity sensor 26 works to detect the internal temperature and humidity. When the temperature is high, the industrial control integrated computer 27 controls the semiconductor refrigeration piece 23 to work, and the cold end emits cold energy. At the same time, the fan three 24 works, and the internal air is sucked to the cold end through the gaps between the fan rack 25 and the square frame 21. Then, the air is blown into the box body 1 from the front to be diffused, so that the internal temperature is lowered. When the temperature is low, the industrial control integrated computer 27 controls the supply current direction of the semiconductor refrigeration piece 23 to switch so that the cold end originally facing inward is switched to the hot end. The fan three 24 then blows out the heat and diffuses it into the box body 1 to increase the temperature, so as to achieve the temperature control effect.

[0033] While the semiconductor refrigeration sheet 23 is working, the fan 2 19 is working, sucking in external air through the gaps between the fan cover 20 and the four corners of the shell 18, and then blowing it out after contacting the semiconductor refrigeration sheet 23, so that unnecessary heat or cold is blown out to dissipate, avoiding affecting the normal operation of the semiconductor refrigeration sheet 23. When the humidity is high, the industrial control all-in-one machine 27 controls the motor 16 to work, and drives the baffle 10 to move down through the threaded connection between the screw rod 12 and the threaded sleeve 15. At the same time, the fan 1 9 works to suck in external air and continuously blow it into the box body 1, replenishing oxygen through air circulation, or dehumidifying with the semiconductor refrigeration sheet 23 to increase the temperature, so that the seeds are maintained in a dry and low-temperature storage environment.

[0034] In this embodiment, a plurality of baskets 6 are placed in the thermal insulation lining 2 , and the bottom of each basket 6 is densely populated with micropores.

[0035] The basket 6 is used to separately place different seeds, so that one box 1 can place multiple seeds at the same time.

[0036] In this embodiment, a grid frame 7 is placed at the bottom of the thermal insulation liner 2 , and the basket 6 is placed on top of the grid frame 7 .

[0037] The mesh frame 7 is matched with the microporous setting at the bottom of the basket 6. For some seeds that may precipitate liquid, the precipitated liquid can be separated from the seeds to avoid the seeds from getting moldy due to moisture. After the precipitated liquid evaporates, the humidity in the box 1 increases, and dehumidification can be performed by using a fan 9 and a semiconductor refrigeration sheet 23.

[0038] In this embodiment, a mesh cover 17 is screwed onto the inner side of the thermal insulation lining 2 corresponding to the screw rod 12 and the outer periphery of the slide rod 11, and protective nets are screwed onto the outward end of the fan cover 8 and the outward and inward ends of the shell 18.

[0039] The mesh cover 17 and the protective net are used to protect the normal use of the internal fans and the shield 10, and also have a certain effect of preventing foreign objects from entering.
