Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a local cooling device for a grain pile. Background Art

[0002] During the storage process of grain, the temperature of some parts of the grain pile may be too high sometimes. The local high temperature will not only accelerate the deterioration of grain quality, but also form "humid heat diffusion", that is, the moisture in the grain pile will be transferred from the high-temperature part to the low-temperature part along the direction of heat transfer, causing the moisture content of the grain in the low-temperature part to increase, and even causing grain storage accidents such as mildew and caking, which is very detrimental to the safe storage of grain. Some granaries use ventilation pipes to extend into the grain to blow air and dissipate heat.

[0003] After searching, the Chinese patent announcement number CN214800930U is found, which discloses a local cooling single-tube fan device for ventilation of grain storage bins. When using this patent, the outlet pipe and the connecting pipe are inserted into the grain, and the telescopic rod is started. The telescopic rod is extended and the temperature sensor is inserted into the grain. The insertion depth of the temperature sensor can be adjusted according to actual conditions. At the same time, the temperature display can display the temperature of the lower part of the grain in real time. When the temperature sensor detects that the temperature exceeds the set value, it will trigger the fan to start, and the fan's working cold air will be blown into the bottom of the grain through the connecting pipe and the outlet pipe. At the same time, the buzzer alarms, the prompt light lights up, the motor rotates, and the eccentric wheel pushes the sliding rod to slide back and forth on the fixed box, driving the prompt light to move back and forth to improve the warning effect. After the temperature recovers, the temperature sensor shuts down all components.

[0004] However, the grains are densely packed underneath, and the gaps between the grains are relatively small. Direct ventilation does not allow for much space for airflow to circulate, so the cooling effect has certain limitations. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, the local cooling device for a grain pile includes a base plate 1, the top of the base plate 1 is bolted to a bracket 101, the bracket 101 is U-shaped with the opening facing downward, a temperature testing assembly is provided at the bottom of the base plate 1, the temperature testing assembly includes an electric push rod 501 fixedly connected to the bottom of the base plate 1, the bottom of the electric push rod 501 is fixedly connected to a temperature sensor 502, a temperature display 503 is fixedly connected to the bracket 101, the temperature display 503 is electrically connected to the temperature sensor 502, an indicator light 504 is fixedly connected to the bracket 101, the indicator light 504 is electrically connected to the temperature sensor 502, the temperature in the grain pile is detected by the temperature sensor 502, and the temperature of the grain is displayed by the temperature display 503.

[0026] The top of the base plate 1 is rotatably connected to the mounting cylinder 2, and the bottom of the mounting cylinder 2 is fixedly connected to the air outlet pipe 201. The top of the mounting cylinder 2 is provided with an air supply assembly, which includes a fan 202 bolted to the bracket 101, and the air outlet of the fan 202 is connected to the air supply pipe 203. The other end of the air supply pipe 203 is rotatably connected to the mounting cylinder 2, and the air supply pipe 203 is communicated with the mounting cylinder 2. A number of ventilation holes are provided on the outer wall of the air outlet pipe 201. When the fan 202 is started, cold air enters the mounting cylinder 2 through the air supply pipe 203, and then enters the air outlet pipe 201 through the mounting cylinder 2, and is finally blown out through the ventilation holes to cool the grain.

[0027] A stirring mechanism is provided in the mounting cylinder 2, and the stirring mechanism includes a mounting rod 403. The outer wall of the mounting rod 403 is hinged with several circumferentially arranged stirring rods 404. The outer wall of the air outlet pipe 201 is provided with an avoidance groove 406. The end of the stirring rod 404 extends out from the avoidance groove 406 and is fixedly connected to a limiting block 405. The stirring rod 404 is limited by the limiting block 405 to prevent the stirring rod 404 from being completely retracted into the air outlet pipe 201, which is inconvenient for the next extension. The stirring rod 404 has a certain elasticity, which facilitates the stirring rod 404 to enter and exit the avoidance groove 406.

[0028] The stirring mechanism also includes a telescopic component, which is used to drive the installation rod 403 to move up and down. The telescopic component includes a hydraulic cylinder 401 fixedly connected to the top of the installation tube 2. The movable end of the hydraulic cylinder 401 is fixedly connected to a horizontal plate 402. The horizontal plate 402 slides up and down along the inner wall of the installation tube 2. The installation rod 403 is fixedly connected to the bottom of the horizontal plate 402. The horizontal plate 402 is driven by the hydraulic cylinder 401 to drive the installation rod 403 to move up and down.

[0029] A power assembly is also provided on the base plate 1, which is used to drive the air outlet pipe 201 to drive the stirring rod 404 to rotate. The power assembly includes a driven gear 301 fixedly connected to the outer wall of the air outlet pipe 201. The top bolt of the base plate 1 is connected to the rotating motor 302. The output end of the rotating motor 302 is fixedly connected to the driving gear 303. The driving gear 303 is engaged with the driven gear 301. When the rotating motor 302 is started, the rotating motor 302 drives the driving gear 303 to rotate. The driving gear 303 is engaged with the driven gear 301, thereby driving the driven gear 301 to drive the air outlet pipe 201 to rotate.

[0030] Working principle: Insert the air outlet pipe 201 into the grain pile, then fix the bottom plate 1 to the top of the grain bin, extend the temperature sensor 502 into the grain pile through the electric push rod 501, adjust the insertion depth of the temperature sensor 502 according to the actual situation, and at the same time, the temperature display 503 displays the temperature of the lower part of the grain in real time, and drive the horizontal plate 402 to move the installation rod 403 downward through the hydraulic cylinder 401. When the installation rod 403 moves downward, it drives multiple groups of stirring rods 404 to extend out of the air outlet pipe 201. When the temperature sensor 502 detects that the temperature exceeds the set value, the fan 202 starts, and the wind blows into the bottom of the grain through the air supply pipe 203 and the air outlet pipe 201 to cool the grain. At the same time, the rotating motor 302 is started, and the rotating motor 302 drives the The driving gear 303 rotates, and the driving gear 303 engages with the driven gear 301, thereby driving the driven gear 301 to drive the air outlet pipe 201 to rotate, and the air outlet pipe 201 drives the installation cylinder 2 and the stirring rod 404 to rotate, to stir the grain, increase the gap between the grains, allow the gas to circulate, and improve the cooling effect. When the temperature sensor 502 detects that the temperature exceeds the set value, the indicator light 504 flashes to attract the attention of the management personnel. When it is necessary to pull the air supply pipe 203 out of the grain pile, the hydraulic cylinder 401 is controlled to make the horizontal plate 402 drive the installation rod 403 to move upward. When the installation rod 403 moves upward, it will drive the stirring rod 404 to retract into the air outlet pipe 201, reducing the resistance when the air supply pipe 203 is lifted.
