DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example: Figure 1-6As shown, the present invention is an intelligent meteorological granary with a multi-parameter detection function, including a granary 1 and a meteorological automatic station 4. There are multiple granaries 1 and meteorological automatic stations 4, and the distance between the two is known. The meteorological automatic station 4 is used to detect ambient temperature and ambient humidity parameters, and evaluate the storage condition of grain through temperature and humidity parameters; a ventilation mechanism 3 is provided in the granary 1, and a circular track 102 is provided on the inner wall of the granary 1. A driving mechanism 2 is connected to the circular track 102, and the driving mechanism 2 is connected to the ventilation mechanism 3; the driving mechanism 2 drives the ventilation mechanism 3 to move in the granary 1 to ventilate and dry the grain at different positions in the granary 1.

[0027] like Figure 4-6As shown, the annular track 102 is connected to a gear ring 101, the driving mechanism 2 includes a moving seat 201, the moving seat 201 is connected to a roller 204 that is connected to the annular track 102, and the roller 204 is provided with a plurality of rollers 204 that are respectively arranged on both sides of the annular track 102; to ensure that the moving seat 201 moves stably on the annular track 102, a driving motor 202 is installed on the moving seat 201, and the driving motor 202 is connected to a gear 203 that meshes with the gear ring 101; the driving motor 202 drives the gear 203 to rotate, thereby driving the moving seat 201 to move on the annular track 102; the ventilation mechanism 3 includes an arc-shaped back plate 301, an arc-shaped back plate 302, and an arc-shaped back plate 303. The back plate 301 is installed on the lower surface of the movable seat 201, and the lower end of the curved back plate 301 is fixedly connected to the bottom plate 303, and a pair of movable ventilation plates 302 arranged in an eight-shaped shape are connected to the curved back plate 301. The ventilation plates 302 are provided with a plurality of ventilation holes, which are rectangular holes and are arranged side by side on the ventilation plates 302. Filter plates 3021 are installed at the ventilation holes. The diameter of the filter holes on the filter plates 3021 is smaller than the diameter of the grain to prevent the grain from passing through the filter plates 3021. A closed air chamber is formed between the two ventilation plates 302 and the curved back plate 301. The upper and lower ends of the curved back plate 301 are provided with track grooves slidably connected to the ventilation plates 302. The 302 is provided with a sliding shaft that slides with the track groove, and one side of the ventilation plate 302 is in contact with the curved back plate 301; a sliding groove 3031 is provided on the bottom plate 303, and a slider 304 is slidably connected to the sliding groove 3031. One end of the ventilation plate 302 is rotatably connected to the slider 304, and the bottom end of the ventilation plate 302 is in contact with the bottom plate 303, and the two ventilation plates 302 are close to each other. To prevent food from entering the air chamber, the ventilation mechanism 3 also includes a hot air blower 309, which is provided with a pair. The hot air blower 309 is connected to an air duct 310, and a plurality of ventilation holes are provided on the surface of the air duct 310. The air duct 310 is arranged inside the air chamber; the movable seat 20 1 is equipped with a rotating motor 305, which is connected to a rotating shaft 306. The lower end of the rotating shaft 306 is connected to a rotating disk 307. A first connecting rod 308 is connected between the rotating disk 307 and the slider 304. When the rotating motor 305 drives the rotating disk 307 to rotate, it drives the slider 304 to move back and forth. When the slider 304 moves back and forth, it drives the two ventilation plates 302 to move back and forth, constantly changing the contact position and contact area between the ventilation plates 302 and the grain. The hot air blower 309 blows hot air into the air chamber and blows it out evenly through the filter plate 3021 on the ventilation plate 302 to dry the grain, thereby improving the ventilation and drying effect of the grain.

[0028] Preferably, a pair of spiral blades 311 are rotatably connected to the bottom plate 303, a crankshaft 312 is connected to the rotating shaft of the spiral blades 311, and a second connecting rod 313 is connected between the crankshaft 312 and the ventilation plate 302. When the ventilation plate 302 moves, the crankshaft 312 is driven to move in a circular motion, driving the spiral blades 311 to rotate, thereby achieving the purpose of stirring and dispersing the nearby grain, thereby increasing the contact amount between the ventilation plate 302 and the grain.

[0029] Preferably, a diverter plate 3041 is fixedly connected to the slider 304 , and the diverter plate 3041 has a conical structure, and the diverter plate 3041 reduces the resistance when the ventilation plate 302 moves.

[0030] A plurality of temperature sensors 5 and humidity sensors 6 at different heights are installed on the arc-shaped back plate 301 to detect the temperature and humidity of grains at different depths in the granary 1 respectively.

[0031] When the grain needs to be ventilated and dried, the hot air blower 309 starts to blow hot air into the air chamber, and the hot air flows through the ventilation plate 302 to the inside of the granary 1 to dry the grain; at the same time, the rotating motor 305 drives the rotating disk 307 to rotate, and the rotating disk 307 drives the slider 304 to move back and forth, thereby driving the two ventilation plates 302 to move back and forth, and the movement of the ventilation plate 302 drives the spiral blade 311 to rotate continuously, increasing the contact amount between the grain and the ventilation plate 302, and the driving mechanism 2 drives the ventilation mechanism 3 to move slowly in the granary 1, drying the grain at various positions in the granary 1, thereby improving the uniformity of grain drying.

[0032] This embodiment also discloses a grain storage method, using the above-mentioned intelligent weather granary, the method comprising the following steps:

[0033] Step 1: Based on the microbial growth and development conditions of different grain types, a 3-7 day temperature and humidity accumulation index is established to evaluate the quality of grain over a period of time. The specific definition is:

[0034] ;

[0035] Where T(m) and S(m) are the effective accumulated temperature and humidity of grain in the mth layer, respectively; Td and Te are the effective daily grain temperature and humidity, respectively; Te and Se are the temperature and humidity thresholds of grain, respectively, which are constants for the selected grain types; and Nd is the effective number of days. Danger levels are divided according to the growth and development laws of microorganisms. When the danger level exceeds the standard level, granary 1 needs to be ventilated and dried.

[0036] Step 2: Analyze the mutual influence of the external environment temperature, the temperature of different granaries 1, and the real-time temperature and humidity of grain. Calculate different weight coefficients based on factors such as the distance and correlation between different granaries 1 and surrounding automatic meteorological stations 4, and establish a model for the influence of the external environment temperature and humidity on grain temperature. The specific formula is:

[0037] ;

[0038] Wherein, T(n) is the grain temperature, and when n=0, it is the granary temperature; i is the number of automatic weather stations near the granary; Ti, Pi, and SI are the temperature, air pressure, and relative humidity of the corresponding automatic weather station, respectively; a, b, and c are the weight coefficients of temperature, air pressure, and relative humidity, respectively; m represents the warehouse type as a constant; and di is the distance weight of the automatic weather station, which is calculated as the percentage of the distance of a single automatic weather station to the distance of all automatic weather stations. i can be set to 1, which means that only a single automatic weather station is used for calculation, in which case di is 1;

[0039] Step 3: By analyzing the quality of the grain in steps 1 and 2, the storage status of the grain in each granary 1 is determined, and the grain is ventilated and dried by starting the driving mechanism 2 and the ventilation mechanism 3 in the granary 1.
