[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1
[0025] Please see Figures 1 to 6This utility model provides a technical solution: a grain storage anti-condensation device, comprising a grain storage body 1 and a sealing cover 2. A temperature and humidity detector 3 is installed on the inner wall of the grain storage body 1. A cavity frame 4 is installed on the outer surface of the grain storage body 1. A fan 5, a dustproof net 6, and a first servo motor 7 are installed inside the cavity frame 4. A threaded rod 8 with the same center as the output shaft of the first servo motor 7 is installed at the output end of the first servo motor 7. A threaded ring block 9 is connected to the outer surface of the threaded rod 8. A T-shaped slider 10 is installed on one side of the threaded ring block 9, and a baffle 1 is installed on the other side of the threaded ring block 9. 1. A sealing block 12 is provided on the outer surface of the baffle 11. A second servo motor 13 is installed on the top of the sealing cover 2. A disc 14 with the same center as the output axis of the second servo motor 13 is installed at the output end of the second servo motor 13. An annular slider 15 is installed on the outer surface of the disc 14. A support rod 16 is installed at the bottom of the disc 14. A V-shaped adjusting rod 17 is rotatably connected to the front of the support rod 16 via a shaft. A heater 18 is provided at the bottom of the V-shaped adjusting rod 17. An electric push rod 19 is rotatably connected to the bottom of the disc 14 via a shaft. A circular block 20 is installed on the inner top wall of the sealing cover 2.
[0026] Specifically, the ventilation openings facilitate ventilation inside the grain silo body 1, the fan 5 helps to better dissipate internal moisture from the grain silo body 1, and the dustproof net 6 serves to block dust.
[0027] Please see Figures 2 to 3 Ventilation openings are provided on both sides of the grain silo body 1, and the positions of the ventilation openings correspond to the positions of the fan 5 and the dustproof net 6, respectively.
[0028] Specifically, the T-shaped slider 10 plays a guiding role inside the T-shaped groove, improving the stability of the baffle 11 moving up and down. The baffle 11 facilitates the sealing of the ventilation opening.
[0029] Please see Figures 2 to 3 The inner wall of the cavity frame 4 is provided with a T-shaped groove with the left and right direction as the depth direction and the up and down direction as the length direction. The end of the T-shaped slider 10 is located inside the T-shaped groove, and the T-shaped slider 10 can slide along the length direction of the T-shaped groove.
[0030] Specifically, the cooperation between the threaded rod 8 and the threaded ring block 9 facilitates the up-and-down movement of the baffle 11, and the setting of the sealing block 12 improves the sealing performance when closed.
[0031] Please see Figures 2 to 6 The end of the threaded rod 8 away from the first servo motor 7 is rotatably connected to the inner wall of the cavity frame 4, and the sealing block 12 abuts against the inner wall of the cavity frame 4.
[0032] Specifically, the cooperation between the annular slider 15 and the annular groove serves to assist the rotation of the heater 18 and improve the stability of the heater 18 during rotation adjustment.
[0033] Please see Figures 1 to 4 The sealing cap 2, disc 14, annular slider 15 and annular block 20 are all at the same center. The inner surface of the annular block 20 is provided with an annular groove with the depth direction in the up and down direction. The end of the annular slider 15 is located inside the annular groove.
[0034] Specifically, it facilitates the heater 18 to penetrate deep into the grain silo body 1, and facilitates the adjustment of the position of the heater 18 inside the grain silo body 1.
[0035] Please see Figures 1 to 4 The movable end of the electric push rod 19 is rotatably connected to the end of the V-shaped adjusting rod 17. The distance from the rotatable connection point of the electric push rod 19 and the V-shaped adjusting rod 17 to the axis of the disc 14 is less than the maximum radius of the ring block 20. The sealing cover 2 is sleeved on the end of the grain bin body 1. The position of the ring block 20 is located inside the grain bin body 1.
[0036] During use, the temperature and humidity inside the grain silo body 1 are detected by the temperature and humidity detector 3. The sealing cover 2 is fitted onto the feed inlet of the grain silo body 1 to seal the feed inlet. When ventilating and dehumidifying the inside of the grain silo body 1, the fan 5 works to allow the moisture inside the grain silo body 1 to be discharged through the ventilation opening. The dustproof net 6 plays a role in dust prevention. The heater 18 works inside the grain silo body 1 to dry the grain, so that the temperature and humidity inside the grain silo body 1 are within a suitable range to prevent grain condensation. The distance from the rotatable connection point of the electric push rod 19 and the V-shaped adjusting rod 17 to the axis of the disc 14 is less than the maximum radius of the annular block 20, which facilitates the heater 18 to penetrate into the grain silo body 1. When adjusting the heating position of the heater 18, the movable end of the electric push rod 19 is rotatably connected to the V-shaped adjusting rod 17. When the movable end of the electric push rod 19 retracts, the V-shaped adjusting rod 17 rotates around the rotatable connection point of the support rod 16 and the V-shaped adjusting rod 17 as the center, causing the heater 18 to tilt. Then, the second servo motor 13 drives the disc 14 to rotate forward and backward within a 360-degree range, so that the annular slider 15 plays an auxiliary role in rotation inside the annular groove. This improves the stability of the heater 18's rotation and facilitates the adjustment of the heater 18's heating position inside the grain silo body 1. Some of the hot air generated during heating is discharged from the grain silo body 1 through the vent. When the grain silo body 1 is closed, the first servo motor 7 drives the threaded rod 8 to rotate. The threaded rod 8 is connected to the threaded ring block 9, and the end of the T-shaped slider 10 is located inside the T-shaped groove. This causes the threaded ring block 9 to drive the baffle 11 to move upward, guiding the T-shaped slider 10 to move inside the T-shaped groove. This causes the baffle 11 to close the vent, and the sealing block 12 abuts against the inner wall of the cavity frame 4, improving the sealing performance during closure and enhancing practicality.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
