[0014] The present invention provides a storage device and method for forage germplasm resources, which has the following beneficial effects: (1) In the present invention, the positioning block can be moved to fit into the limiting hole and be limited, so that the position of the placement rack is limited. The gap between the placement racks can be adjusted according to the height of the grass, so that the internal space of the shell can be used to the greatest extent and the grass seeds can be stored without being affected, thereby improving the practicality of the device. When the unlocking rod is no longer in contact with the unlocking block, the unlocking block is driven to move outward by the reset of the No. 1 spring, and then the placement rack is released from the limit. The placement rack can be quickly adjusted again, thereby reducing the difficulty of using the device.

[0015] (2) The invention drives the wind shield to rotate toward the bottom through the movement of the transmission rod. After the wind shield rotates, the air outlet is opened. When the placement rack is adjusted, the air outlet can be closed and opened when the adjustment is completed for storage. This prevents dust from forming at the corners of the air outlet, making it difficult to close the air outlet. This improves the stability of the device when in use. The water mist on the surface of the ventilation baffle is scraped off by the movement of the wiper toward the bottom. This prevents the formation of condensation beads inside the housing when the temperature is increased due to the difference between the internal and external temperatures when the placement rack is adjusted. This prevents the internal humidity of the housing from being too high, causing some forage to be unable to be stored normally.

[0016] (3) In the present invention, when the wiper moves toward the top, it will contact the reset block and push the wiper to move in the direction of the ventilation baffle and reset, so that the wiper will not contact the ventilation baffle when moving toward the top, preventing the condensation beads from being driven in the opposite direction to the top and unable to detach from the ventilation baffle.

[0017] (4) The invention enables the self-locking rod to move and get stuck inside the lock tongue, so that the protective door cannot rotate. After the protective door is closed, the device will automatically limit its position without manual operation. The self-locking rod is driven to move away from the lock tongue by the No. 4 spring reset. After the self-locking rod moves, it no longer contacts the lock tongue, so that the protective door can be opened and unlocked quickly, thereby improving work efficiency.

[0026] When the present embodiment is working: the forage is placed on the top of the placing rack 54, and then the position of the placing rack 54 is manually adjusted to the desired height. After the placing rack 54 is adjusted, the placing rack 54 is pushed in the direction close to the limiting rod 52. The movement of the placing rack 54 will drive the arc-shaped card block 55 to move in the direction of the limiting rod 52. The placing rack 54 will contact the arc-shaped card block 55 and snap into the inside of the limiting rod 52. Then, the unlocking block 57 is pressed inwardly. The unlocking block 57 moves and contacts the card block 58. The unlocking block 57 moves and drives the card block 58 to move away from the unlocking block 57. The card block 58 moves and snaps into the inside of the limiting hole and is limited, so that the position of the placing rack 54 is limited. The gap between the placing racks 54 can be adjusted according to the height of the forage, and the outer shell 1 can be used to the greatest extent. The internal space of the shelf 54 is ensured, and the forage seeds are not affected by the height between the shelf 54 when being stored, so as to prevent the forage seeds from being blocked by the shelf 54, thereby improving the practicability of the device. After the unlocking block 57 is completely moved to the innermost part, the unlocking block 57 is no longer in contact with the unlocking rod 510, and the unlocking rod 510 is driven to move to the bottom by the No. 2 spring reset. After the unlocking rod 510 moves, it will block the unlocking block 57. When the shelf 54 needs to be adjusted, the unlocking rod 510 is manually pulled to the top. When the unlocking rod 510 is no longer in contact with the unlocking block 57, the unlocking block 57 is driven to move outward by the No. 1 spring reset, and then the limit of the shelf 54 is released, and the shelf 54 can be quickly adjusted again, thereby reducing the difficulty of using the device.
