[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-8 The utility model provides a technical solution: a grain air-drying device with a modular assembly structure, including a bottom air-drying bin 1, a modular air-drying bin 2, an air-drying air-permeable net 3, a positioning hole 4, a positioning block 5, a fixing column 6, a connecting plate 7, a fixing cap 8, a supporting frame 9, a discharging mechanism 10, a discharging barrel 11, an auxiliary block 12, a discharging box 13, a discharging trough 14, a fixing bracket 15, a side plate 16, a spring 17, a movable plate 18, a fixing plate 19 and a fixing hole 20.

[0033] When using the grain air drying device with the modular assembly structure, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, support frames 9 are welded on the left and right sides of the bottom air-drying bin 1, and positioning holes 4 are opened at the edges of the upper ends of the bottom air-drying bin 1 and the modular air-drying bin 2, and the lower end of the modular air-drying bin 2 is provided with positioning blocks 5 which are arranged one-to-one with the positioning holes 4. First, the modular air-drying bin 2 drives the positioning blocks 5 to be inserted into the positioning holes 4 at the upper end of the bottom air-drying bin 1, and the side surfaces of the bottom air-drying bin 1 and the left and right sides of the upper end of the bottom air-drying bin 1 are welded with fixing columns 6. Now the connecting plate 7 is sleeved on the outer surface of the fixing column 6, and then the fixing cap 8 is threadedly connected with the fixing column 6 by rotating the fixing cap 8. The fixing caps 8 are respectively fitted at the upper and lower ends of the connecting plate 7, so as to facilitate the docking installation between the modular air-drying bin 2 and the bottom air-drying bin 1. Then the above operation can be repeated to modularly splice and assemble the modular air-drying bins 2 at adjacent positions. The assembly and connection methods between the modular air-drying bins 2 at adjacent positions and the modular air-drying bins 2 and the bottom air-drying bin 1 are exactly the same. The number of modular air-drying bins 2 can be increased or decreased according to the amount of grain. Through modular splicing and assembly, it is convenient to store different amounts of grain, which is highly practical.

[0034] When the device is assembled, the grain is added to the device from the top of the entire device, and air-drying air-permeable nets 3 are arranged around the modular air-drying bin 2 and on the front and back sides of the bottom air-drying bin 1. Through the arrangement of the air-drying air-permeable nets 3, the wind can pass through the air-drying air-permeable nets 3 to perform all-round air-drying treatment on the grain in the device, and the overall air-drying efficiency is high. When the air-dried grain needs to be unloaded, combined with Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a discharge mechanism 10 is provided at the lower end of the bottom air-drying bin 1, and the discharge mechanism 10 is used to control the discharge of grains, and the discharge mechanism 10 includes a discharge barrel 11 fixedly connected to the lower end of the bottom air-drying bin 1, an auxiliary block 12 fixedly connected to the front and rear ends of the discharge barrel 11, a discharge box 13 sleeved on the outside of the discharge barrel 11, and a discharge trough 14 opened on the right side of the lower end of the auxiliary block 12;

[0035] By pushing the movable plate 18 upward, the movable plate 18 drives the fixed plate 19 to slide with the side plate 16, and the movable plate 18 squeezes the spring 17, causing the spring 17 to undergo elastic deformation, and the protrusion at the upper end of the fixed plate 19 is pulled out of the fixing hole 20 opened at the upper end of the fixed bracket 15, thereby releasing the limit on the fixed bracket 15, and then slowly pushing the unloading box 13 to the left, the unloading box 13 slides with the auxiliary block 12, and the unloading box 13 drives the unloading chute 14 to move to the right, so that the unloading chute 14 coincides with the opening in the middle of the unloading barrel 11, so that the grain stored in the device can be unloaded through the overlap between the opening in the middle of the unloading mechanism 10 and the unloading chute 14, and the size of the overlapping part can be adjusted by sliding between the unloading box 13 and the auxiliary block 12, so that the size of the grain unloading rate can be adjusted, which is very convenient to use.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
