[0006] The above technical objectives of the present invention are achieved through the following technical solutions:
[0007] A semi-underground granary cooling experimental platform comprises an underground frame, wherein the outer peripheral wall of the buried frame is provided with a plurality of evenly distributed guide cylinders, wherein an adjustment structure is provided inside one of the guide cylinders, and support rods are slidably provided inside the other guide cylinders, and the top ends of the support rods and the adjustment structures are commonly connected to the experimental granary, the top end of the experimental granary is provided with a conical umbrella cap, the top end of the conical umbrella cap is provided with a ventilation structure, the top end of the conical umbrella cap is provided with an insulation cover, the top end of the insulation cover is provided with a photovoltaic structure, and the interior of the buried frame is provided with a heat-conducting structure.
[0008] Furthermore, the insulation cover is arranged in a conical shape, and a plurality of evenly distributed support plates are provided at the bottom end of the insulation cover. The support plates are fixedly connected to the outer wall of the conical umbrella cap. There is a gap between the insulation cover and the conical umbrella cap, and the taper of the insulation cover is smaller than the taper of the conical umbrella cap.
[0009] Furthermore, the ventilation structure includes an air guide tube, an electric fan is provided inside the air guide tube, a plurality of connecting rods are provided at the top end of the air guide tube, and the top ends of the connecting rods are fixedly connected to the bottom end of the heat insulation cover.
[0010] Furthermore, the photovoltaic structure includes a plurality of arc-shaped photovoltaic panels, which are evenly fixed on the top of the insulation board. A battery is provided inside the insulation board, and the battery is connected to the electric fan.
[0011] Furthermore, the adjustment structure includes an adjusting screw, which is threadedly connected to the guide cylinder. An annular adjustment plate is provided at the top of the adjusting screw. The top of the annular adjustment plate is rotatably connected to the experimental granary, and the side wall of the annular adjustment plate is provided with several connecting holes.
[0012] Furthermore, the heat-conducting structure includes a metal rod, and a plurality of metal rods are provided.

[0013] In summary, the present invention has at least one of the following beneficial technical effects:
[0014] 1. This semi-underground granary cooling experimental platform uses support plates to securely connect the insulation plate and the conical umbrella cap.

[0015] 2. This semi-underground granary cooling experimental platform uses a sealing ring to make the metal rod and the experimental granary sliding and sealing connection. In addition, since the metal rod is fixedly connected to the buried frame, and the bottom end passes through the buried frame and is inserted into the soil, since the heat in the soil is relatively stable, when the temperature in the granary rises, the heat can be introduced into the soil through the metal rod to achieve the purpose of cooling the grain.

DETAILED DESCRIPTION
[0022] The present invention will be described in further detail below with reference to the accompanying drawings.
[0023] Example:
[0024] Reference Figure 1 - Figure 4 The utility model discloses a semi-underground granary cooling experimental platform, which includes an underground frame 1. The outer peripheral wall of the buried frame 1 is provided with a number of evenly distributed guide cylinders 2, one of which is provided with an adjustment structure 3, and the interiors of the other guide cylinders 2 are all slidably provided with support rods 4, and the tops of each support rod 4 and the adjustment structure 3 are commonly connected with an experimental granary 5, wherein the bottom end of the experimental granary 5 is conical, and the bottommost end is provided with an electric discharge port for discharging grain, and the top of the outer peripheral wall of the experimental granary 5 is provided with a filling port for filling grain, and the top of the experimental granary 5 is provided with a conical umbrella cap 6, which is fixed to the experimental granary 5 by bolts, and the top of the conical umbrella cap 6 is provided with a ventilation structure 7, and the top of the conical umbrella cap 6 is provided with a heat insulation cover 8, and the top of the heat insulation cover 8 is provided with a photovoltaic structure 9, and the interior of the buried frame 1 is provided with a heat conducting structure 10.
[0025] In this embodiment, when installing the granary, the buried frame 1 is installed underground, and the top surface of the buried frame 1 is flush with the ground. The adjustment structure 3 and the support rod 4 are inserted into the interior of the guide cylinder 2, and the experimental granary 5 is fixed to the top of the support rod 4. By rotating the adjustment structure 3, the experimental granary 5 can be controlled to move up and down.
[0026] After the experimental granary 5 is installed, the heat-conducting structure 10 is inserted into the interior of the experimental granary 5. When grain is stored in the granary, the heat-conducting structure 10 is evenly dispersed inside the grain, effectively absorbing the heat in the grain and conducting the heat into the ground through the buried frame 1, thereby achieving the effect of cooling the grain.
[0027] The conical umbrella cap 6 is used to close the upper opening of the experimental granary 5, and the ventilation structure 7 is used to ventilate the granary to prevent the evaporation of moisture in the granary, which leads to a high water vapor content in the granary. The heat-insulating cover 8 is used to further insulate the top of the granary to prevent the heat radiation from the sun from causing an excessive increase in the temperature in the granary. The photovoltaic structure 9 is set to provide power for the ventilation structure 7.
[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the insulation cover 8 is arranged in a conical shape, and a plurality of evenly distributed support plates 11 are provided at the bottom end of the insulation cover 8. The support plates 11 are fixedly connected to the outer wall of the conical umbrella cap 6. There is a gap between the insulation cover 8 and the conical umbrella cap 6, and the taper of the insulation cover 8 is smaller than the taper of the conical umbrella cap 6.
[0029] In this embodiment, the heat insulation board and the conical umbrella cap 6 are fixedly connected to each other by support plates 11, and a gap is provided between the heat insulation cover 8 and the conical umbrella cap 6. When the ventilation device pushes the air inside the experimental granary 5 upward, the air is dispersed by each support plate 11, so that the flowing air evenly fills the gap. Therefore, when exposed to sunlight, the flowing air can prevent heat from being transferred from the heat insulation board to the conical umbrella cap 6, thereby effectively preventing the heat generated by the heat radiation from the sunlight from causing the temperature inside the experimental granary 5 to rise.
[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the ventilation structure 7 includes an air guide tube 71, an electric fan 72 is provided inside the air guide tube 71, and a plurality of connecting rods 73 are provided at the top end of the air guide tube 71. The top end of the connecting rod 73 is fixedly connected to the bottom end of the insulation cover 8.
[0031] In this embodiment, the air guide tube 71 is used to install the electric fan 72, and the connection stability between the air guide tube 71 and the insulation cover 8 is improved by setting the connecting rod 73.
[0032] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the photovoltaic structure includes a plurality of arc-shaped photovoltaic panels 91, which are evenly fixed on the top of the insulation board. A battery 92 is provided inside the insulation board, and the battery 92 is connected to the electric fan 72.
[0033] In this embodiment, the arc-shaped photovoltaic panel 91 absorbs thermal radiation and converts it into electrical energy, and the electrical energy is stored inside the battery 92. The battery 92 and the electric fan 72 are interconnected by a wire, so that electrical energy can be effectively provided to the electric fan 72, so as to achieve the effect of ventilating the experimental granary 5 through the electric fan 72.
[0034] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the adjustment structure 3 includes an adjusting screw 31, which is threadedly connected to the guide cylinder 2. An annular adjustment plate 32 is provided at the top of the adjusting screw 31. The top of the annular adjustment plate 32 is rotatably connected to the experimental granary 5, and a side wall of the annular adjustment plate 32 is provided with a plurality of connection holes 33.
[0035] In this embodiment, by inserting the pry bar into the connecting hole 33 and rotating the pry bar, the annular adjustment plate 32 and the adjusting screw 31 are rotated. Since the adjusting screw 31 is threadedly connected to the guide cylinder 2, the adjusting screw 31 can be effectively pushed to move upward, thereby achieving the purpose of pushing the experimental granary 5 to move upward.
[0036] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the heat-conducting structure 10 includes a metal rod 101, and a plurality of metal rods 101 are provided. The metal rod 101 is fixedly connected to the bottom end of the buried frame 1 and passes through the buried frame 1. The top end of the metal rod 101 passes through the bottom wall of the experimental granary 5 and extends to the interior of the experimental granary 5. A sealing ring 102 is provided at the position where the metal rod 101 contacts the experimental granary 5.
[0037] In this embodiment, the metal rod 101 is slidably and sealedly connected to the experimental granary 5 through the sealing ring 102, and since the metal rod 101 is fixedly connected to the buried frame 1, and the bottom end passes through the buried frame 1 and is inserted into the interior of the soil, since the heat in the soil is relatively stable, when the temperature in the granary rises, the heat can be introduced into the soil through the metal rod 101 to achieve the purpose of cooling the grain.
[0038] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
