[0021] Refer to Figure 1 and Figure 2, the utility model relates to a grain drying bin structure with uniform air inlet. The main structure includes an outer shell 1. The grains to be dried enter the inside of the outer shell 1 and contact with hot air. After the moisture in the grains is taken away, it is discharged from the outer shell 1, realizing the separation of moisture from the grains and achieving the purpose of rapid drying. An inlet 2 and an outlet 3 are respectively provided at the top and bottom of the outer shell 1. Grains enter the outer shell 1 from the upper inlet 2. During the falling process, the grains are fully dispersed and contact with hot air. The dried grains are discharged from the lower outlet 3. When multiple drying operations are required, the grains discharged from the outlet 3 are lifted to the inlet 2 by a hoist and the drying operation is repeated to realize the cyclic drying treatment of the grains. A main bin 4 and a plurality of sub-bins 5 are arranged inside the outer shell 1. The size of the main bin 4 is generally larger than that of the sub-bins 5. The sub-bins 5 are distributed at various positions inside the outer shell 1. A plurality of air holes 6 are provided on the side walls of the main bin 4 and the sub-bins 5. The hot air passes through the air holes 6 and then enters or exits the outer shell 1. An air inlet pipe 7 communicating with the sub-bins 5 and an air outlet pipe 8 communicating with the main bin 4 are provided on the outer shell 1. The hot air enters the plurality of sub-bins 5 through the air inlet pipe 7, passes through the air holes 6 on the sub-bins 5 and enters various positions inside the outer shell 1, so as to contact the grains at various positions inside the outer shell 1 more fully, making the drying of the grains at various positions more uniform. The hot air with moisture passes through the air holes 6 on the main bin 4 and is discharged from the air outlet pipe 8. An air outlet fan 9 is provided on the air outlet pipe 8. The air outlet fan 9 is used to extract the hot air with moisture from the main bin 4. A plurality of branch pipes 10 are connected in series to the air inlet pipe 7. Each branch pipe 10 is connected to the bottom of the sub-bin 5. An air inlet fan 11 is provided on the branch pipe 10. Inside the air inlet fan 11, there is a fan blade driven by a motor to rotate, generating the power for air inlet by the rotation of the fan blade. The bottom of the air inlet fan 11 is movably connected with a filter net 12. The air inlet fan 11 is used to send hot air into the sub-bin 5. Such a structure makes the air volume and air speed of the hot air entering each sub-bin 5 more uniform, further ensuring the uniformity of the drying of the grains at various positions inside the outer shell 1, reducing the number of repeated drying times, improving the drying efficiency and environmental protection, reducing the energy consumption of the overall drying operation. The setting of the filter net 12 can block impurities such as dust that may exist in the hot air, prevent them from entering the inside of the air inlet fan 11 and the outer shell 1, ensure the service life of the air inlet fan 11, and reduce the possible pollution to the grains. After using for a period of time, the filter net 12 is removed for cleaning or replacement to ensure the filtering effect under long-term use.

[0022] Preferably, a filter chamber 13 is provided at the bottom of the intake fan 11. The filter chamber 13 is used to accommodate and fix the filter net 12. The top of the filter chamber 13 is fixed with a limit net plate 14 by welding or bolts. A plurality of mesh holes are provided on the limit net plate 14. The filter net 12 is arranged between the limit net plate 14 and the bottom of the filter chamber 13. The setting of the limit net plate 14 can be used to fix and limit the filter net 12, ensuring the firmness of the position of the filter net 12. At the same time, the setting of a plurality of mesh holes will not block the filter net 12, ensuring the filtering effect of the filter net 12.

[0023] Preferably, referring to Figure 3 and Figure 4 , an installation opening 15 is provided on one side of the filter chamber 13. The installation opening 15 penetrates through the end of the filter net 12. The filter net 12 enters and exits the filter chamber 13 from the installation opening 15 to achieve rapid replacement operation. A baffle 16 for closing the installation opening 15 is slidably connected vertically at the installation opening 15. Specifically, a chute is provided on the side of the intake fan 11, and the baffle 16 is slidably connected vertically in the chute. A power rod 17 for driving the baffle 16 to slide up and down is provided on the intake fan 11. In such a structure, when the filter net 12 is installed, the power rod 17 is used to drive the baffle 16 to slide upward, exposing the installation opening 15, so that the filter net 12 can be quickly pulled out from the installation opening 15 for cleaning or replacement. After the filter net 12 is replaced, the power rod 17 is used to drive the baffle 16 to descend to block the installation opening 15, ensuring the stability of the filter net 12 in the filter chamber 13, and making the replacement operation of the filter net 12 more convenient and efficient.

[0024] Preferably, a fixing plate 18 is fixed on the intake fan 11 by welding or bolts. The power rod 17 penetrates through the fixing plate 18 and is threadedly connected thereto. The bottom end of the power rod 17 is rotatably connected to the baffle 16 through a bearing. In such a structure, only by rotating the power rod 17, the bottom of the power rod 17 can be rotated up and down under the action of the threaded connection, and then the baffle 16 rotatably connected to the bottom can slide up and down. Moreover, the threaded connection structure can be used to keep the baffle 16 in the moved position, improving the convenience of controlling the sliding of the baffle 16 and ensuring the firmness of the position of the baffle 16 after sliding.

[0025] Preferably, the main bin 4 is located below the feed inlet 2. The tops of the main bin 4 and the auxiliary bins 5 are both conical. A plurality of auxiliary bins 5 are annularly and arrayedly distributed outside the main bin 4. In such a structure, the grains falling from the feed inlet 2 are evenly dispersed at various positions on the side of the main bin 4 along the conical shape of the top of the main bin 4, making the falling grains more dispersed and enabling better contact with the hot air, further improving the drying effect. The arrangement of a plurality of auxiliary bins 5 arrayedly distributed around the main bin 4 makes the hot air distribution at each position more uniform, further improving the efficiency and uniformity of grain drying.

[0026] Preferably, a hot blast stove 19 is provided at the end of the intake pipe 7. The hot blast stove 19 can generate heat by burning biomass materials or coal, so as to heat the air and send it into the intake pipe 7, enabling the temperature of the hot air to be adaptively adjusted according to actual usage requirements, and meeting the drying requirements of different quantities and types of grains.

[0027] Working principle: The structure of the present utility model is configured by arranging a main bin body 4 and a plurality of sub-bin bodies 5 inside the outer shell body 1. After the hot air enters the plurality of sub-bin bodies 5 from the intake pipe 7, it is discharged from a plurality of air holes 6 on the side walls of the sub-bin bodies 5 and evenly distributed at various positions inside the outer shell body 1, contacting the grains to carry away the moisture therein. After passing through the air holes 6 on the main bin body 4, it is discharged from the outlet pipe 8 under the action of the outlet air blower 9, enabling the hot air to be evenly distributed at various positions inside the outer shell body 1, thereby making more uniform and sufficient contact with the grains falling at various positions, ensuring the uniformity of the drying operation, reducing the number of repeated drying times, improving the drying efficiency and environmental protection, and effectively reducing the energy consumption of the drying operation; a plurality of communicating branch pipes 10 are provided on the intake pipe 7, and an intake air blower 11 is provided on the branch pipes 10. The bottom of the intake air blower 11 is movably connected with a filter net 12. Such a structure enables the hot air in the intake pipe 7 to enter each sub-bin body 5 evenly through the intake air blower 11 and then be distributed inside the outer shell body 1 from the air holes 6 on the plurality of sub-bin bodies 5, further ensuring the uniformity of the wind force at various positions inside the outer shell body 1. The filter net 12 is provided to block possible impurities in the hot air, preventing the impurities from entering the interior of the intake air blower 11 and the outer shell body 1, ensuring the service life of the intake air blower 11 and avoiding possible contamination of the grains.
