Description

Technical Field

[0001] The present invention relates to the technical field of grain storage, in particular to a grain ventilation device for a vertical silo. Background Art

[0002] At present, in the modern grain storage system, vertical silos are the mainstream grain storage facilities. Their ventilation effect directly determines the quality of grain preservation and the safety of long-term storage. A scientific and reasonable ventilation system plays a decisive role in maintaining a stable temperature and humidity environment in the grain pile, inhibiting the reproduction of microorganisms, and preventing the occurrence of pests.

[0003] Traditional vertical granaries usually use a one-way airflow ventilation system, which leads to uneven airflow distribution inside the grain pile, obvious ventilation dead corners, insufficient ventilation in the central area, and affects the overall ventilation effect. At the same time, the ventilation effect of the grain pile depends on natural infiltration, and when the grain is in a stacked state, the gaps between the grains are small, making it difficult for air to circulate and penetrate naturally. This makes the ventilation effect inside and outside the grain pile uneven, and the internal space becomes hot and moldy due to poor air circulation due to long-term stacking. At the same time, the shape of the grain pile cannot be processed during the grain stacking process, causing the grain to clump, further affecting the ventilation effect of the grain, and unable to ensure that the grain is in a suitable environment for long-term storage. Summary of the Invention

[0025] Technical effects and advantages of the present invention:

[0026] In the present invention, its storage system adopts a double-layer silo structure consisting of a silo body and an inner lining. The porous characteristics of the inner lining ensure gas exchange between the grain pile and the outside world. The ventilation system consists of a ventilator and a ventilator to form a two-way airflow circulation. The pipe of the ventilator directly transports the treated air to the core area of ​​the grain pile, and the surrounding holes form a natural exhaust channel. The dual channels of the ventilator simultaneously realize ventilation and exhaust, allowing fresh air to enter the grain pile and effectively discharge the internal hot air. The system can automatically adjust the ventilation intensity according to the state of the grain pile, while maintaining a suitable storage environment, effectively controlling the moisture evaporation rate to prevent local over-drying or moisture.

[0027] In the present invention, the push plate realizes three-dimensional ventilation through compound motion, and its revolution drives the overall circulation of grain. The rotation of the three-rod frame drives the push plate to complete radial telescopic motion. At the same time, the engagement of the frame plate and the third gear causes the push plate to rotate. This mode of motion not only promotes full contact between grain and air, but also forms a convection channel in the grain pile, effectively breaking the temperature stratification of the grain pile and preventing local heating; inhibiting the breeding of pests through mechanical disturbance; promoting uniform evaporation of water and avoiding condensation. The airflow disturbance generated during the movement can also drive the discharge of dust and improve the storage environment.

[0028] In the present invention, the cleaning brush moves along the inner wall of the lining under the guidance of the limiting rod, and the raised rod cooperates with the wavy circular groove to make the cleaning brush vibrate axially. This design removes blockages in the holes through mechanical friction, and the periodic knocking of the counterweight produces vibration wave conduction. Vibration conduction promotes the loosening of the grain pile and improves air permeability. The micro-airflow generated during the cleaning process carries away the attached dust, and the periodic vibration prevents the grain from becoming compacted. At the same time, the movement trajectory of the cleaning brush covers the entire warehouse wall to ensure that there are no blind spots for cleaning.

[0029] In the present invention, when the second support plate rotates with the vent cylinder as the axis, its end remains in contact with the bottom of the silo, and the vibration generated by the vibration mechanism is transmitted to the discharge port. The horizontal rotation promotes the movement of the accumulated material, and the vertical vibration destroys the material arch structure. The combined movement produces a grain fluidization effect, significantly reduces the residual amount, and increases the silo discharge rate. It can also simultaneously clean the silo bottom during the unloading process to achieve integrated operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0041] Reference Figure 1 - Figure 9 As shown, the present invention provides a technical solution: a vertical silo grain ventilation device, comprising a silo body 1, a top cover 2 fixedly connected to the top of the silo body 1, an inner lining 3 fixedly connected to the inner wall of the silo body 1, a top plate 4 fixedly connected to the top of the inner lining 3, a three-rod frame 5 installed at the bottom of the top cover 2, a push plate 6 provided at one end of the three-rod frame 5, a plurality of counterweights 7 provided on the inner wall of the silo body 1, and the vertical silo grain ventilation device further comprising a propeller 8 and a cleaning brush 9;

[0042] A processing mechanism is installed at the bottom of the three-rod frame 5, which drives the push plate 6 to revolve along the inner diameter of the liner 3. At the same time, the push plate 6 moves back and forth repeatedly during the revolution and drives itself to rotate.

[0043] The stirring mechanism is connected to the processing mechanism in a transmission manner so that when the three-bar frame 5 rotates, the propeller 8 is driven to rotate to stir the grain inside the liner 3;

[0044] The cleaning mechanism is connected to the processing mechanism to drive the cleaning brush 9 to revolve along the inner diameter of the liner 3 and perform friction cleaning;

[0045] Auxiliary mechanism; the auxiliary mechanism is connected to the cleaning mechanism to drive the cleaning brush 9 to move up and down repeatedly during revolution, thereby increasing the cleaning force of the cleaning brush 9 on the liner 3;

[0046] Vibration assembly; the vibration assembly is connected to the processing mechanism to drive the counterweight 7 to strike the liner 3, so that the liner 3 itself vibrates and shakes off the surface dirt;

[0047] The ventilation mechanism is installed on the outside of the cylinder silo body 1 to process the air in the top cover 2.

[0048] Reference Figure 1 -and Figure 8 As shown, in this embodiment: the processing mechanism includes:

[0049] The motor 10 is provided with a first gear 11 at the output end of the motor 10, a circular plate 12 is fixedly connected to the outer side of the three-rod frame 5, the surface of the first gear 11 is meshed with the outer side of the circular plate 12, the outer side of the three-rod frame 5 is rotatably connected with three second gears 13, the surface of the second gear 13 is meshed with the top of the inner diameter of the top plate 4, the surface of the three-rod frame 5 is provided with three slide grooves 14, the inner wall of the slide groove 14 is slidably connected with a T-shaped plate 15, the bottom of the T-shaped plate 15 is fixedly connected with an extension plate 16, the other end of the extension plate 16 is fixedly connected with a slot plate 17, the second gear 13 is connected to the outer side of the three-rod frame 5, and the second gear 13 is connected to the outer side of the three-rod frame 5. The bottom of the three-rod frame 5 is fixedly connected to an L-shaped plate 18, the bottom of the groove plate 17 is rotatably connected to the third gear 19, the top of the push plate 6 is fixedly connected to the bottom of the third gear 19, the surface of the three-rod frame 5 is fixedly connected to a frame plate 20, the frame plates 20 are distributed on both sides of the third gear 19, and one side of the third gear 19 is meshed with the frame plate 20. The bottom of the three-rod frame 5 is fixedly connected to a ventilator 21, the bottom of the ventilator 21 is fixedly connected to a slide plate 22, and the bottom of the push plate 6 is rotatably connected to a sleeve plate 23, and the sleeve plate 23 is slidably connected to the slide plate 22 at one end close to the slide plate 22. , the device puts grain into the lining 3 through the feed port on the top of the top cover 2 for storage. When the grain needs to be taken out, the discharge port at the bottom of the silo body 1 is opened to discharge the grain stored in the lining 3. During the period when the grain is stored in the lining 3 for a long time, the device can control the motor 10 to start and stop at a fixed time through the control device 40. When the motor 10 starts running, the motor 10 starts the first gear 11 to rotate and drive the meshing circular plate 12 to rotate, which makes the circular plate 12 rotate synchronously with the three-bar frame 5, and when the three-bar frame 5 rotates, the second gear 13 and The top of the inner wall of the top plate 4 is in contact with the top plate 4, and the meshing connection between the two causes the second gear 13 to rotate along the inside of the top plate 4 when the three-rod frame 5 rotates. When the second gear 13 rotates, the second gear 13 drives the L-shaped plate 18 to deflect with the second gear 13 as the center of the circle, which causes the L-shaped plate 18 to push the slot plate 17 to move when it rotates, and then drives the extension plate 16 and the T-shaped plate 15 to slide along the slide groove 14. Since the rotation of the L-shaped plate 18 drives the slot plate 17 to move synchronously, the rotation of the L-shaped plate 18 drives the slot plate 17 to slide repeatedly with the inner diameter of the slide groove 14 as the moving track;

[0050] When the slot plate 17 is driven and moved repeatedly by the rotation of the L-shaped plate 18, the third gear 19 will also move back and forth with the slot plate 17, wherein the frame plate 20 is sleeved on the outside of the third gear 19, and when the third gear 19 moves along the inner diameter of the frame plate 20, the frame plate 20 will push the third gear 19 to rotate, which makes the third gear 19 rotate when it moves inward and rotate in the opposite direction when it moves outward, and the push plate 6 is fixed to the bottom of the third gear 19 and will operate synchronously with the third gear 19, and the sleeve plate 23 is telescopically and slidably connected to the slide plate 22. When the push plate 6 moves back and forth, it will rotate along one end of the sleeve plate 23 and drive the slide plate 22 and the sleeve plate 23 to retract and move to adapt to the forward and backward movement trajectory of the push plate 6. This makes the three-rod frame 5 rotate When the push plate 6 moves, it will drive the push plate 6 to rotate synchronously along the inner diameter of the liner 3, and the push plate 6 will move back and forth repeatedly and rotate itself. Through the movement and rotation of the push plate 6 inside the liner 3, the grain on the inner wall surface of the liner 3 is scraped, and the grain stored in the liner 3 is stirred during rotation. The push plate 6 is more likely to shuttle through the accumulated grain when it rotates, and it is not easy to be unable to move due to the tight accumulation of grain. In addition, its rotation during movement is not easy to cause squeezing damage to the grain, preventing the movement of the push plate 6 from squeezing and damaging the grain. When the push plate 6 contacts the surface of the liner 3, the grain stuck to the surface of the liner 3 is scraped off, avoiding the grain sticking to the inner diameter of the liner 3. At the same time, its forward and backward movement trajectory can push the grain inside the liner 3 to be evenly dispersed, avoiding the grain sticking and clumping after long-term accumulation.

[0051] In actual use, the processing mechanism can be started and run for a period of time to achieve dispersed processing of the grain inside the lining 3, so that the external grain is temporarily away from the surface of the lining 3. At this time, the holes on the surface of the lining 3 will not be blocked by the grain, and the air permeability of the lining 3 is increased, which allows the grain in the area passed by the push plate 6 to come into contact with the air discharged from the holes of the lining 3. At the same time, the grain is stirred and dispersed by the push plate 6, and the accumulated heat and moisture inside the grain are also more easily discharged through the lining 3 to ensure the dryness and safety of the grain for long-term storage and ensure the overall quality of the grain. During operation, the rotation and forward and backward movement of the push plate 6 not only achieves uniform dispersion of the grain, but also promotes air circulation between the grains, further improving the ventilation efficiency of the vertical silo. This design not only improves the safety and stability of grain storage, but also reduces the economic losses caused by grain mildew. It is a major innovation in grain storage management in vertical silos.

[0052] Reference Figure 1 - Figure 8 As shown, in this embodiment: the stirring mechanism includes:

[0053] The first support plate 24, the bottom of the propeller 8 is rotatably connected to one end of the first support plate 24 through a rotating shaft, one end of the three-bar frame 5 is rotatably connected to the fourth gear 25, the bottom of the fourth gear 25 is fixedly connected to the top of the propeller 8, and the internal rotation of the three-bar frame 5 is connected to the transmission gear 26, one side of the transmission gear 26 is meshed with the fourth gear 25, and the other side of the transmission gear 26 is meshed with the second gear 13. The transmission gear 26 is driven by the rotation of the second gear 13 to transmit the synchronous rotation to the fourth gear 25, which makes the propeller 8 rotate with the fourth gear 25. At this time, the three-bar frame 5 is in a rotating state, and the rotation of the three-bar frame 5 drives the propeller 8 to rotate in a circular revolution while rotating, wherein the bottom of the propeller 8 is supported by the first support plate 24. The propeller 8 is supported by the impeller 8 and rotates at the same time when it is placed in the grain pile, which will stir the grain inside the lining 3. At the same time, the grain is driven upward by the propeller 8. The spiral conveying of the propeller 8 makes the grain at the bottom and top of the lining 3 mixed with each other, so as to achieve the mixing of the grain stored in the lining 3, and avoid the central area of ​​the grain from overheating and fermenting after long-term storage due to insufficient ventilation. In addition, the rotation and revolution of the propeller 8 also enhance the contact area between the grain and the air, further promote the discharge of moisture inside the grain, and help maintain the dry state of the grain. The first support plate 24 serves as a supporting structure to stabilize the stability of the propeller 8 during the rotation process, realize uniform ventilation during the grain storage process, and avoid the risk of mildew during the grain storage process.

[0054] Reference Figure 1 - Figure 5 As shown, in this embodiment: the cleaning mechanism includes:

[0055] The second support plate 27, one end of the second support plate 27 is fixedly connected to the limit rod 28, the top of the limit rod 28 is fixedly connected to the bottom of the three-rod frame 5, the cleaning brush 9 is slidably connected to the surface of the limit rod 28, the top of the cleaning brush 9 is fixedly connected with a meniscus 29, and the second gear 13 is driven to revolve and rotate by the rotation of the three-rod frame 5, so that the three-rod frame 5 drives the limit rod 28 to revolve with the ventilator 21 as the center of the circle, wherein the cleaning brush 9 slides on the surface of the limit rod 28, and the surface structure of the meniscus 29 is connected to the top The inner diameter of the plate 4 is consistent with that of the plate 4, which allows the meniscus 29 to slide up and down on the inner diameter surface of the top plate 4 without being able to tilt left or right, so as to constrain the position of the cleaning brush 9, so that it is always on the surface of the limit rod 28 and one side is in contact with the inner diameter surface of the liner 3. The revolution of the cleaning brush 9 in contact with the inner diameter surface of the liner 3 allows the friction between the two to clean the inner diameter of the liner 3, so that dust clogged in the holes of the liner 3 can be removed by the cleaning brush 9, while preventing the surface of the liner 3 from adsorbing dirt and foreign matter.

[0056] When there is no grain stored inside the device, the staff can use the water spray pipe to spray water on the inside of the liner 3 and cooperate with the cleaning brush 9 to clean the liner 3. When there is grain stored inside the device, the rotating cleaning of the cleaning brush 9 can dredge the holes in the liner 3, ensure the air circulation of the liner 3, and realize the exchange and circulation of the air inside the liner 3 and the outside air. In this process, as the cleaning brush 9 continuously rotates and scrubs, the air inside the liner 3 is stirred, forming a pressure difference with the outside air. This pressure difference prompts the outside fresh air to enter the device through the holes in the liner 3, and at the same time, the stale air inside the device is discharged, thereby realizing effective ventilation of the grain in the vertical silo.

[0057] The design of this device not only cleverly utilizes the interaction between various components, but also fully considers the dual needs of ventilation efficiency and cleaning effect. During grain storage, continuous rotation cleaning ensures that the ventilation holes are unobstructed, effectively avoiding the problem of poor air circulation caused by dust accumulation. At the same time, the device is easy to operate and can realize automatic ventilation and cleaning functions without complicated manual intervention, greatly reducing labor costs and maintenance difficulty.

[0058] Reference Figure 4 、 Figure 5 and Figure 8 As shown, in this embodiment: the auxiliary mechanism includes:

[0059] The raised rod 30 is fixedly connected to one side of the meniscus 29, and a wavy groove 31 is provided on the inner diameter of the top plate 4. One end of the raised rod 30 is slidably connected to the inner wall of the wavy groove 31. When the cleaning brush 9 rotates in a circle, the raised rod 30 will slide along the inside of the wavy groove 31. Since the wavy groove 31 is a circular wave shape, the raised rod 30 will produce a wavy up and down movement when sliding along the wavy groove 31. The raised rod 30 is fixedly connected to the meniscus 29, which will drive the cleaning brush 9 to rise and fall synchronously, which makes the cleaning brush 9 move up and down repeatedly when moving in a circle, and fits against the inner diameter surface of the lining 3. The friction force generated by repeated movement enhances the sliding cleaning force of the cleaning brush 9 along the inside of the lining 3, so as to realize the efficient brushing of the inner wall of the lining 3 by the cleaning brush 9.

[0060] Reference Figure 2 、 Figure 8 and Figure 9 As shown, in this embodiment: the vibration component includes:

[0061] The outer gear 32 has several outer gears 32. The bottom of the outer gear 32 is fixedly connected to a transmission rod 33. The transmission rod 33 is rotatably connected to the top of the cylinder body 1. The bottom of the transmission rod 33 is fixedly connected to a push rod 34. The inner diameter of the cylinder body 1 is fixedly connected to several slide rods 35. The surface of the slide rod 35 is slidably connected to a movable plate 36. The counterweight block 7 is fixedly connected to the bottom of the movable plate 36. One side of the movable plate 36 is fixedly connected to a spring 37. The other end of the spring 37 is fixedly connected to the inner diameter of the cylinder body 1. When the circular plate 12 is driven to rotate by the first gear 11, since several outer gears 32 are engaged with the outer side of the circular plate 12, they will be driven by the circular plate 12 to rotate synchronously, which makes the outer gear 32 drive the transmission rod 33 and the push rod 34 to rotate counterclockwise. Figure 9 As shown in FIG, by rotating the push rod 34 counterclockwise 180 degrees, it is pressed against the surface of the movable plate 36 to squeeze the movable plate 36, so that the movable plate 36 slides backward along the slide rod 35 and presses the spring 37 to store force. When the push rod 34 is rotated more than 180 degrees, the push rod 34 slides out of the surface of the movable plate 36. At this time, the push rod 34 is no longer in contact with the movable plate 36, and the spring 37 is not subjected to the squeezing force, and the rebound pushes the movable plate 36 to move in the opposite direction. The spring 37 pushes the movable plate 36 to reset and drives the counterweight block 7 to the surface of the liner 3. The surface moves, and the thrust of the spring 37 will push the slide rod 35 to the surface of the lining 3. The impact force generated by the collision of the counterweight block 7 with the surface of the lining 3 will cause the lining 3 to vibrate to a certain extent. Through this vibration, the grain in contact with the inside of the lining 3 will also be driven by the impact force generated by the vibration, which makes the grain accumulated inside the lining 3 loose due to the vibration. At the same time, the vibration can shake off the dirt and adhered grain on the surface of the lining 3, and when the grain needs to be discharged, it can avoid the grain piling up too tightly and causing the discharge port to be blocked.

The ventilation mechanism 39 is connected to the ventilator 21 through a pipe. A control device 40 is fixedly connected to one side of the cylinder body 1. Two ventilators 38 are placed on both sides of the cylinder body 1. One of the ventilators 38 is the output end that continuously delivers dry fresh air to the inside of the cylinder body 1, and the other ventilator 38 is the exhaust end that actively extracts the air inside the cylinder body 1, so as to realize the continuous flow of air between the cylinder body 1 and the liner 3. In addition, the ventilation mechanism 39 is connected to the wavy circular groove 31 through two pipes, and the surface of the ventilator 21 has a number of air holes, and its internal space is divided into two, which makes the two pipes of the ventilation mechanism 39 respectively Through the two independent channels of the ventilator 21, one delivers fresh air to the center of the grain pile, and the other half of the space extracts the accumulated air in the grain pile through the pipe, so that the center of the grain pile can also be efficiently ventilated to avoid the mildew of the grain due to long-term accumulation, which affects the quality of the grain. At the same time, this ventilation method can also effectively reduce the humidity in the grain pile, keep the grain dry, and further extend the storage time of the grain. In addition, the control device 40 serves as a control terminal, which can monitor the air quality and humidity inside the silo body 1 in real time, adjust the working status of the two ventilators 38 according to actual needs, realize intelligent control, and improve ventilation efficiency. The entire ventilation device is reasonably designed, simple in structure, and easy to maintain, providing effective ventilation guarantee for grain storage in the vertical silo.
