The bottoms of the multiple hollow tubes 61 are located below the storage box 1, and are commonly fixed with a bottom plate 63. The center of the bottom of the storage box 1 is connected with a central screw 64 through a bearing seat 65. A bottom plate screw sleeve 66 is fixed at the center of the bottom plate 63. The central screw 64 is threadedly connected to the bottom plate screw sleeve 66. A rotating wheel 67 is fixed at the bottom of the central screw 64. The rotating wheel 67 is rotated to control the up and down movement of the multiple hollow tubes 61, so as to avoid the hollow tubes 61 from obstructing the storage and retrieval of biomass.

[0029] Furthermore, a sealing device 7 is provided at the connection between the hollow tube 61 and the storage box 1;

[0030] The sealing device 7 includes a sealing plug 71 and a sealing ring 72. The sealing plug 71 is sleeved on the outside of the hollow tube 61 and is threadedly connected to the bottom of the storage box 1. A sealing ring 72 is arranged inside the sealing plug 71 to prevent the biomass from sliding up and down through the hollow tube 61 and falling out of the storage box 1.

[0031] Furthermore, a rain cover 5 is fixed on the storage box 1 outside the air inlet 3 and the air outlet 4 to prevent rainwater or external water droplets from falling into the storage box 1 through the air inlet 3 and the air outlet 4.

[0032] During the specific implementation process, when the biomass is placed in the storage box 1, the central screw 64 is rotated by manually shaking the rotating wheel 67, and the bottom plate 63 and multiple hollow tubes 61 are moved upward synchronously through the bottom plate screw sleeve 66, so that the hollow tubes 61 pass through the biomass and rise to the air circulation area above the box body. The hollow tubes 61 cooperate with the vents 62 at the upper and lower positions to allow air to circulate between the inside of the biomass and the top of the storage box 1.

[0033] Example 2

[0034] In order to increase the gas circulation space inside the biomass, improvements are made on the basis of Example 1, such as Figure 4-7 As shown, in this embodiment, a biomass propping device 8 is provided in the hollow tube 61; the biomass propping device 8 includes a rectangular vent hole 81, a folding propping leaf 82, a lifting shaft 83, a connecting rod 84, and a lifting column 85.

A lifting column 85 is integrally formed at the bottom of the lifting shaft 83. The lifting column 85 is connected by sliding up and down along the hollow tube 61, so that the folding propping leaf 82 can be folded and opened like an umbrella frame structure, propping up the biomass, so that the rectangular vent 81 has a larger contact space with the inside of the biomass, thereby increasing the gas flowability inside the biomass. The bottom end of the lifting column 85 is connected to a propping transmission mechanism 9. The propping transmission mechanism 9 includes a driven gear 91, a gear ring 92, a driving gear 93, a motor bracket 94, and a motor 95. The driven gear 91 corresponds to the number of the hollow tubes 61 and is installed on the bottom surface of the base plate 63 through a bearing. The lifting column 85 is threadedly connected to the center of the driven gear 91 to achieve the lifting and lowering effect of the lifting column 85 and the lifting shaft 83. The gear ring 92 is meshed with the driven gear 91, and the driving gear 93 is meshed with the gear ring 92. The motor bracket 94 is fixed to the bottom surface of the base plate 63. A motor 95 is fixedly installed on the motor bracket 94. The output end of the motor 95 is key-connected with the driving gear 93. The opening and folding of the folding propping leaves 82 are achieved by the motor 95 driving the gear and screw transmission.

[0035] During the specific implementation process, the motor 95 is started, driving the driving gear 93 to rotate, and the driving gear 93 and the ring gear 92 are transmitted, so that the ring gear 92 drives multiple driven gears 91 to rotate, and the self-rotation of the driven gear 91 causes the lifting column 85 to rise and fall, and the lifting shaft 83 rises and falls synchronously at the same time, and the folding and opening of the folding support leaf 82 is realized through the connecting rod 84, increasing the rectangular vent 81 and the air circulation space inside the biomass, so that the air inside the biomass can circulate with the air above the storage box 1 through the rectangular vent 81 at the upper and lower positions of the hollow tube 61.

[0036] Example 3

[0037] In order to enhance the gas flow inside the storage box 1 and increase the filtering effect on the external humid air, the embodiment 2 is improved, such as Figure 4 As shown, in this embodiment, an air filter 31 and a fan 41 are installed on the air inlet 3 and the air outlet 4 respectively.

[0038] During the specific implementation process, the air filter 31 can effectively prevent water molecules in the air from entering the storage box 1, and the fan 41 can increase the exchange efficiency between the storage box 1 and the external air, thereby increasing the discharge of internal humid air.

[0039] Example 4

[0040] In order to increase the dryness inside the storage box 1, improvements are made based on Example 3, such as Figure 8-9 As shown, in this embodiment, a placement groove 21 is provided on the top cover 2, and a drying box 10 is arranged in the placement groove 21; the drying box 10 includes a box body 101, a placement opening 102, a desiccant vent 103, and a box body top plate 104. The box body 101 is located in the storage box 1 through the placement groove 21, and a placement opening 102 is provided on the upper outer side of the box body 101 for placing a desiccant. The desiccant vent 103 runs through the surface of the box body 101, and a box body top plate 104 is fixed on the top of the box body 101. The area of ​​the box body top plate 104 is larger than that of the placement groove 21, so as to facilitate the replacement of the desiccant.

[0041] During the specific implementation process, the desiccant is placed in the box body 101 through the placement opening 102, and the entire drying box 10 is placed on the placement groove 21, so that the desiccant circulates with the air inside the storage box 1 through the desiccant vent 103 to keep the storage box 1 dry.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
