DETAILED DESCRIPTION

[0032] The preferred embodiments of the utility model will be described below in detail with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0033] Please refer to Figures 1-8 ​The ventilation and cooling mechanism for the grain turnover bin of the embodiment comprises a bin body 1, a hopper mouth 2 is installed at the bottom of the bin body 1, two mirror-symmetrical flap plates 3 are rotationally connected in the hopper mouth 2, ventilation mechanisms 4 are fixedly connected to the outer sides of the two flap plates 3, the ventilation mechanism 4 comprises a plurality of toothed discs one 401 fixedly connected to the outer sides of the two flap plates 3 respectively, a plurality of first supports 402 are fixedly connected to the two sides inside the hopper mouth 2, a plurality of toothed discs two 403 are rotationally connected between the plurality of first supports 402 and are mutually engaged with the plurality of toothed discs one 401 respectively, the radius of the toothed disc two 403 is smaller than the radius of the toothed disc one 401, a plurality of toothed racks 404 are slidingly connected to the two sides inside the hopper mouth 2 and are mutually engaged with the toothed disc two 403 respectively, the function of the ventilation mechanism 4 is to introduce air into the bin body 1 to achieve the purpose of ventilation and cooling; the flap plate 3 is designed to be light and easy to carry, and it is kept in a horizontal state with the ground by a torsional spring 603 in ordinary times; when it is needed to pour out the grain, the valve 9 is opened, and the grain flows from the bin body 1 into the hopper mouth 2 through the valve 9; the grain is first accumulated on the two flap plates 3, and as the amount of the grain increases, the self-weight forces the flap plate 3 to deflect downward; the deflection of the flap plate 3 in turn drives the toothed disc one 401 to rotate synchronously, which in turn causes the rotation of the toothed disc two 403, and finally drives the toothed rack 404 to move; this series of consecutive mechanical actions realizes the effective displacement of the toothed rack 404.

[0034] As shown in Figures 5-7 the top ends of the plurality of toothed racks 404 are fixedly connected with a plurality of column two 405, the top ends of the plurality of column two 405 are fixedly connected with a plurality of pistons 406, a plurality of cylinder two 407 are fixedly connected to the two sides inside the hopper mouth 2, the plurality of pistons 406 are slidingly located in the plurality of cylinder two 407 respectively, the top ends of the plurality of cylinder two 407 are fixedly connected with a plurality of air tubes 408, the plurality of air tubes 408 are installed on the two sides of the inner wall of the bin body 1 respectively, the main function of the column two 405 is to output or suck away the gas in the bin body 1; when the flap plate 3 deflects downward due to force, it drives the toothed rack 404 to move downward, in turn driving the column two 405 and the piston 406 to move downward in the cylinder two 407 synchronously, which realizes the operation of sucking out the gas in the bin body 1; subsequently, the flap plate 3 will gradually deflect upward under the restoring force of the torsional spring 603, which in turn causes the piston 406 to move upward in the cylinder two 407, thereby blowing the gas into the bin body 1; whether it is the process of sucking or blowing, it can effectively accelerate the air flow in the bin body 1, achieving the effect of ventilation and cooling.

[0035] As shown in Figures 3-4As shown, the inner wall of the funnel mouth 2 is fixedly connected with a limiting mechanism 5, which includes a plurality of U-shaped blocks 501 fixedly connected to the inside of the funnel mouth 2, and a plurality of racks 404 respectively located in the plurality of U-shaped blocks 501 and sliding therein. The main function of the limiting mechanism 5 is to limit and guide the racks 404. When the racks 404 slide inside the funnel mouth 2, they will move smoothly at the open end of the U-shaped block 501, and the U-shaped block 501 will play the role of accurately limiting and effectively guiding the racks 404.

[0036] As shown in Figures 3-4 The front end of the flap 3 is fixedly connected with a reset mechanism 6, which includes a plurality of shafts two 601 fixedly connected to the front and rear ends of the two flaps 3 outside, a plurality of second brackets 602 fixedly connected inside the funnel mouth 2, and a plurality of second brackets 602 respectively rotatably connected with the plurality of shafts two 601. The outside of the plurality of shafts two 601 is respectively sleeved with a torsional spring 603. The reset mechanism 6 undertakes the important task of supporting the flap 3 and driving it to reciprocatingly deflect. When the flap 3 is not needed to be used, the torsional spring 603 provides stable support and positioning for the flap 3. When the flap 3 needs to be used, the weight of the grain will cause the flap 3 to deflect downward. Subsequently, in the process of the grain sliding, the elastic force of the torsional spring 603 will cause the flap 3 to deflect upward. This process is not completed in a single time, but under the continuous action of the torsional spring 603, the flap 3 will perform reciprocating deflection movement. This design brings two great benefits: first, the reciprocating deflection of the flap 3 directly collides with the clumped grain, effectively breaking up the grain clumps, reducing the risk of grain clumping; second, the movement of the flap 3 also drives the reciprocating movement of the piston 406, causing the air pipe 408 to continuously inhale and blow at one end inside the bin body 1, thereby enhancing the effect of ventilation and cooling. This process is fully automated and does not require manual intervention, achieving efficient automatic operation.

[0037] As shown in Figures 1-8 The bin body 1 is externally installed with a support frame 7 standing on the ground, the support frame 7 is internally placed with a conveyor belt 8 located below the funnel mouth 2, and the funnel mouth 2 is internally installed with a valve 9. The main function of the support frame 7 is to support and position the bin body 1 and the funnel mouth 2, ensuring the stability of the structure, thereby facilitating the turnover operation of the grain, and the conveyor belt 8 is responsible for efficiently transporting the grain falling from the funnel mouth 2, and the valve 9 is used to regulate the outflow of the grain from the funnel mouth 2, achieving precise control of the grain flow.

[0038] As shown in Figures 5-7As shown, a plurality of dustproof nets 10 are fixedly installed on both sides of the inner wall of the bin body 1, and the other ends of the plurality of air pipes 408 are located in the plurality of dustproof nets 10 respectively; a plurality of protective covers 11 are fixedly connected in the bin body 1, and the plurality of air pipes 408 are located in the plurality of protective covers 11 respectively; the dustproof net 10 has double functions: on the one hand, it can effectively block dust from entering the inside of the bin body 1, and plays an excellent dust blocking role; on the other hand, it can also prevent granular food from blocking the air pipe 408 and the dustproof net 10 itself, and ensure that the exhaust function of the air pipe 408 is not affected; in addition, through the protective cover 11, the pipe body of the air pipe 408 is fully protected and protected.

[0039] In use, the flap 3 is designed to be light and compact, and is supported by a torsion spring 603 in a horizontal state at ordinary times; when the grain in the bin needs to be poured out, the valve 9 is opened, the grain flows into the hopper mouth 2 and first accumulates on the flap 3; as the weight of the grain increases, the flap 3 is deflected downward under stress, and this action is transmitted through a series of gears and racks 404 to drive the piston 406 to move up and down in the cylinder; when the piston 406 moves downward, gas is sucked out from the bin; when the piston 406 moves upward, gas is blown into the bin; this process of sucking and blowing accelerates the flow of air in the bin, achieving the effect of ventilation and cooling; at the same time that the flap 3 deflects, the torsion spring 603 connected to the front end of the flap 3 causes the flap 3 to automatically reset during the grain sliding process, and reciprocating deflection is performed; this process not only helps to break up the grain lumps and reduce the risk of caking, but also enhances the ventilation and cooling effect through the reciprocating movement of the piston 406; the conveyor belt 8 is used for efficient transmission of the falling grain; the valve 9 can regulate the outflow of the grain to achieve precise control; the dustproof net 10 can not only block dust from entering the bin, but also prevent granular food from blocking the air pipe 408, ensuring smooth gas flow; at the same time, the air pipe 408 is wrapped by the protective cover 11 and is fully protected; in summary, the deflection of the flap 3 drives the piston 406 to move, achieving the suction and blowing of the gas in the bin, accelerating the flow of air, and achieving the purpose of ventilation and cooling; at the same time, the reciprocating deflection of the flap 3 helps to break up the grain lumps, the valve 9 controls the flow of the grain, and the dustproof net 10 and the protective cover 11 ensure stable operation of the system.
