[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] A high-efficiency ventilation structure for grain storage includes a grain storage silo 1. A lifting pipe 2 is fixedly connected inside the grain storage silo 1. A spiral blade 3 is rotatably connected inside the lifting pipe 2. A transmission box 4 is fixedly connected to the bottom of the grain storage silo 1. A motor 5 is fixedly connected to the bottom of the transmission box 4. A dust collection box 6 is fixedly connected to one side of the lifting pipe 2. A sieve plate 7 is fixedly connected inside the dust collection box 6. A dust collection drawer 8 is slidably connected to the bottom of the dust collection box 6. An inlet 9 is provided at one end of the lifting pipe 2 near the bottom of the grain storage silo 1, and an outlet 9 is provided at the other end of the lifting pipe 2. When the inlet 10 is opened, the motor 5 is started. Through the transmission structure inside the transmission box 4, the spiral blades 3 inside the lifting pipe 2 are driven to rotate, lifting the grain from the inlet 9 to the outlet 10. The grain then falls onto the sieve plate 7 below the outlet 10. The sieve plate 7 is inclined. The grain passes through the sieve plate 7 and falls into the grain storage bin 1. During this process, the dust mixed in with the grain will pass through the holes of the sieve plate 7 and fall into the dust storage drawer 8. After a certain amount of dust accumulates in the dust storage drawer 8, the operator opens the grain bin cover 15, pulls out the dust storage drawer 8, and cleans away the dust.

[0025] The bottom of the grain storage silo 1 is connected to a grain outlet pipe 11. Inside the grain outlet pipe 11, a spiral blade 12 is rotatably connected. The bottom of the spiral blade 12 is fixedly connected to a connecting shaft, which is coaxially fixedly connected to the output end of the motor 5. A bevel gear 13 is fixedly connected to the outside of the connecting shaft. One end of the spiral blade 12 near the transmission box 4 passes through the side wall of the grain outlet pipe 11 and extends into the interior of the transmission box 4. One end of the spiral blade 12 is fixedly connected to a bevel gear 14. The bevel gear 13 and the bevel gear 14 mesh with each other. When the motor 5 starts, it drives the connecting shaft inside the transmission box 4 to rotate. The connecting shaft drives the spiral blade 13 and the bevel gear 13 to rotate. When the bevel gear 13 rotates, it drives the spiral blade 12 inside the grain outlet pipe 11 to rotate through the bevel gear 14 that meshes with it. When it is necessary to discharge grain, the cover of the grain outlet pipe 11 is opened, and the spiral blade 12 discharges grain during the rotation process.

[0026] A grain storage silo 1 is provided with a grain silo cover 15 on top, and a grain inlet 16 is provided on the grain silo cover 15. Several supports 18 are fixedly connected to the bottom of the grain storage silo 1, and a fan 17 is fixedly connected to one side of the grain storage silo 1. Grain is added into the grain storage silo 1 through the grain inlet 16, and the fan 17 provides forced ventilation for the grain that rolls down from the sieve plate 7.

[0027] The working principle of this utility model is as follows:

[0028] First, the motor 5 is started, and through the connecting shaft fixed to it, the spiral blades 3 inside the lifting pipe 2 are rotated, lifting the grain from the inlet 9 to the outlet 10, and then it falls onto the sieve plate 7 below the outlet 10. The sieve plate 7 is inclined, and the grain falls into the grain storage bin 1 after passing through the sieve plate 7. The fan 17 provides forced ventilation for the grain rolling down from the sieve plate 7. During this process, dust mixed in with the grain will pass through the holes of the sieve plate 7 and fall into the dust collection drawer 8. After a certain amount of dust accumulates in the dust collection drawer 8, the operator opens the grain bin cover 15. Pull out the dust drawer 8 and clean off the dust. This solves the problem of ineffective ventilation of the grain at the bottom of the grain storage bin 1 and reduces dust and impurities in the grain. When it is necessary to discharge the grain, open the cover of the grain discharge pipe 11. The motor 5 drives the connecting shaft inside the transmission box 4 to rotate. The connecting shaft drives the bevel gear 13 to rotate. When the bevel gear 13 rotates, it drives the spiral blade 12 inside the grain discharge pipe 11 to rotate through the bevel gear 14 that meshes with it. During the rotation of the spiral blade 12, the grain is discharged, which improves the grain discharge efficiency and solves the problem of grain discharge blockage.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
