[0002] A grain bin is a special building for storing grains, mainly including bin houses, freight yards, metering, conveying, stacking, cleaning, loading and unloading, ventilation, and drying facilities, and is equipped with instruments such as measurement, sampling, and inspection and testing. Generally, a grain bin is preferably a house-type bin or an underground bin with good moisture-proof, heat-insulating, airtight, or ventilation conditions. Because during the storage process of grains, the grains themselves generate heat. If the storage bin cannot be ventilated and cooled, it will affect the storage of grains.

[0003] Conventional grain bin ventilation usually uses a fan to transport external air into the grain bin for ventilation. However, due to the large size of the grain bin, the required fan power or quantity is also large, and in summer, ventilation needs to be carried out continuously, resulting in large energy consumption. How to achieve energy-saving and efficient ventilation has been a research direction for people. At the same time, when ventilating, it is easy to transport the moisture in the external air into the grain bin, resulting in mildew and damage of the grains. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems of large energy consumption in the prior art and the entry of moisture in the air into the grain bin during ventilation, and to provide a mechanical ventilation device for grain bins.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A mechanical ventilation device for grain bins includes a ventilation pipe connected to the grain bin. A mounting frame is fixedly connected to the upper surface of the ventilation pipe. A fan blade for blowing air into the grain bin is rotatably connected to the surfaces of the mounting frame and the ventilation pipe. A wind cup for driving the fan blade to rotate is rotatably connected to the surface of the mounting frame. A refrigeration component for condensing water vapor is arranged on the surface of the ventilation pipe. A scraper for cleaning water droplets is arranged on the surface of the refrigeration component.

[0007] In some embodiments, the refrigeration component includes a refrigerating machine and a plurality of refrigeration pipes. The refrigerating machine is fixedly connected to the outside of the ventilation pipe for heat dissipation.

[0008] In some embodiments, a reciprocating threaded column for reciprocating the scraper is rotatably connected inside the ventilation pipe. A threaded cap is threadedly connected to the surface of the reciprocating threaded column. The reciprocating threaded column is connected to the scraper through the threaded cap.

[0009] In some embodiments, a connecting shaft is rotatably connected to the surface of the ventilation pipe. A bevel gear is fixedly connected to the lower end of the wind cup and one end of the connecting shaft respectively, and the two bevel gears are meshed with each other. A synchronous pulley is fixedly connected to the other end of the connecting shaft and one end of the reciprocating threaded column respectively, and the two synchronous pulleys are connected by a synchronous belt.

[0010] In some embodiments, a funnel for receiving water droplets is provided at the bottom of the ventilation pipe, and a one-way valve for draining water is fixedly connected to the lower surface of the funnel.

[0015] 1. In the present utility model, by setting the wind cup, the wind power drives the fan blades to rotate continuously, so that the granary can be ventilated continuously, achieving the purpose of saving energy. By setting the refrigeration component, the moisture in the air passing through the ventilation pipe condenses on the surface of the refrigeration pipe, preventing a large amount of moisture from entering the granary and causing the grain to mildew. At the same time, the air will bring the cold air of the refrigeration pipe into the granary, improving the cooling effect.

[0016] 2. In the present utility model, by setting the scraper, the reciprocating threaded column drives the scraper to slide reciprocally on the surfaces of multiple refrigeration pipes, so as to timely clean the water droplets condensed on the surface of the refrigeration pipe, avoiding the moisture being brought into the granary interior by the air again. By setting the exhaust fan, when there is no wind, the air inside the granary is pumped out, creating a negative pressure in the granary, and then the outside air enters the granary interior through the ventilation pipe after separating the moisture, achieving the purpose of cooling.

[0017] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. In the present utility model, the wind blows the wind cup to drive the fan blades to rotate continuously, ventilating the granary continuously, achieving the purpose of saving energy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-5 , a mechanical ventilation device for a granary, including a ventilation pipe 1 connected to the granary. The ventilation pipe 1 is a bent structure. A mounting frame 2 is fixedly connected to the upper surface of the ventilation pipe 1. A fan blade 3 is rotatably connected to the surfaces of the mounting frame 2 and the ventilation pipe 1. A wind cup 4 is rotatably connected to the surface of the mounting frame 2. The fan blade 3 is fixedly connected to the surface of the wind cup 4. The mounting frame 2, the fan blade 3, and the wind cup 4 are all vertically arranged on the surface of the ventilation pipe 1.

[0028] It can be understood that by setting the wind cup 4, the wind power drives the fan blade 3 to continuously rotate, so that the granary can be ventilated continuously, achieving the purpose of saving energy.

[0029] Specifically, a refrigeration assembly 5 is arranged on the surface of the ventilation duct 1, and the refrigeration assembly 5 includes a refrigerator 501 and multiple refrigeration tubes 502. The refrigerator 501 is fixedly connected to the outside of the ventilation duct 1 for heat dissipation, and the multiple refrigeration tubes 502 are arranged inside the ventilation duct 1 for condensing moisture. The multiple refrigeration tubes 502 are staggeredly distributed inside the ventilation duct 1.

[0030] It can be understood that by working of the refrigerator 501, the low temperature is transmitted through the refrigeration pipe 502, so that the moisture in the air passing through the ventilation pipe 1 condenses onto the surface of the refrigeration pipe 502, thereby preventing a large amount of moisture from entering the granary and causing the grain to mold. At the same time, the air will bring the cold air from the refrigeration pipe 502 into the granary, thereby improving the cooling effect.

[0031] Specifically, a scraper 6 for cleaning water droplets is provided on the surface of the refrigeration component 5, a reciprocating threaded column 7 is rotatably connected inside the ventilation pipe 1, a threaded cap 8 is threadedly connected to the surface of the reciprocating threaded column 7, the reciprocating threaded column 7 is connected to the scraper 6 through the threaded cap 8, a connecting shaft 9 is rotatably connected to the surface of the ventilation pipe 1, a bevel gear 10 is fixedly connected to the lower end of the wind cup 4 and one end of the connecting shaft 9 respectively, the two bevel gears 10 are meshed with each other, the other end of the connecting shaft 9 and one end of the reciprocating threaded column 7 are fixedly connected to synchronous wheels 11 respectively, and the two synchronous wheels 11 are connected through a synchronous belt 12 for transmission.

[0032] It can be understood that when the wind cup 4 rotates, it drives the bevel gear 10 to rotate, and the two bevel gears 10 change the transmission direction to make the connecting shaft 9 rotate. With the cooperation of the synchronous belt 12 and the synchronous wheel 11, the reciprocating threaded column 7 is driven to rotate, thereby driving the threaded cap 8 and the scraper 6 to reciprocate on the surface of the refrigeration pipe 502, and the water droplets condensed on the surface of the refrigeration pipe 502 are cleaned in time to prevent moisture from being brought into the granary again by the air.

[0033] Specifically, a funnel 13 is provided at the bottom of the ventilation pipe 1, a one-way valve 14 is fixedly connected to the lower surface of the funnel 13, and a drain pipe is provided on the surface of the one-way valve 14.

[0034] It can be understood that, by providing the funnel 13, it is convenient to collect the water droplets cleaned by the scraper 6 and discharge them through the one-way valve 14 and the drain pipe.

[0035] Specifically, it also includes an exhaust fan 15 for exhausting air from the granary.

[0036] It is understandable that by providing an exhaust fan 15, the air inside the granary is extracted when there is no wind, the granary generates negative pressure, and then the outside air enters the granary through the ventilation pipe 1 after the moisture is separated, thereby achieving the purpose of cooling.

[0037] Specifically, a filter screen 16 is detachably connected inside the ventilation pipe 1 .

[0038] It is understandable that by setting the filter screen 16, it is convenient to filter the dust in the air. At the same time, it can prevent bugs from entering the granary through the ventilation pipe 1.

[0039] Specifically, a shielding plate 17 is fixedly connected to the surface of the mounting frame 2.

[0040] It is understandable that by setting the shielding plate 17, it can prevent rain and snow from entering the granary through the ventilation pipe 1. In the present utility model, in windy weather, the wind drives the wind cups 4 and the fan blades 3 to rotate continuously, and continuously ventilates the granary. The refrigerating machine 501 works to generate low temperature and transfers it to the inside of the ventilation pipe 1 through the refrigerating pipe 502, so that the moisture in the passing air condenses on the surface of the refrigerating pipe 502 to separate the moisture, preventing a large amount of moisture from entering the granary and causing the grain to mildew. At the same time, the air will bring the cold air of the refrigerating pipe 502 into the granary to improve the cooling effect. While the wind cups 4 are rotating, the bevel gears 10 are driven to rotate. By changing the transmission direction through the two bevel gears 10, the connecting shaft 9 rotates. Under the cooperation of the synchronous belt 12 and the synchronous pulley 11, the reciprocating threaded column 7 rotates, driving the threaded nut 8 and the scraper 6 to reciprocate on the surface of the refrigerating pipe 502, and timely cleaning the water droplets on the surface of the refrigerating pipe 502 to the surface of the funnel 13, and discharging them through the one-way valve 14 and the drain pipe, preventing the moisture from being brought into the granary interior by the air again. Under the action of the filter screen 16, the dust and bugs in the air are filtered. When there is no wind, the exhaust fan 15 works to extract the air inside the granary, creating a negative pressure in the granary, and then enabling the outside air to enter the granary interior after separating the moisture through the ventilation pipe 1, achieving the purpose of cooling.
