Description

Technical Field

[0001] This utility model relates to the field of grain storage moisture-proof ventilation technology, specifically a grain storage moisture-proof ventilation structure device. Background Technology

[0002] Grain storage is a crucial link in ensuring food security and reducing post-harvest losses. The temperature and humidity control of the storage environment directly affects the quality of stored grain. A damp environment easily leads to mold and insect infestation, causing not only significant grain losses but also potentially producing harmful substances such as aflatoxin, jeopardizing food safety. Ventilation, as the core means of moisture control in grain storage, requires continuous and even air circulation to remove excess moisture from the storage room and maintain suitable storage humidity.

[0003] However, current grain storage moisture-proof ventilation devices on the market generally have technical defects, making it difficult to meet the needs of efficient moisture prevention. The ventilation coverage is limited, and it is easy to create local dead zones. Traditional devices mostly use a fixed height and fixed angle air outlet structure, and the airflow can only cover specific areas in the storage room. Air stagnation easily occurs in the bottom layer, corners and other places, resulting in persistently high humidity in these areas, which become the "disaster areas" for grain mold. Although some devices can manually adjust the air outlet angle, the adjustment process is cumbersome and cannot adapt to the ventilation needs of different heights in the storage room in real time. The upper and lower layers of grain are prone to the problem of "the upper layer is too dry and the lower layer is too damp", which reduces the quality of grain storage. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof and ventilation structure for grain storage. This structure solves the problem that traditional devices often use fixed-height and fixed-angle air outlet structures, which can only cover specific areas in the storage room. Air tends to stagnate in the bottom and corners, resulting in persistently high humidity in these areas and causing grain to mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A moisture-proof and ventilation structure for grain storage includes a fan installed on the outside of the grain storage room, with a duct installed on the top of the fan, the duct passing through the left side of the grain storage room, and a guide pipe passing through the right side of the grain storage room; it also includes a movable component for adjusting the outlet height and angle of the fan; and a swing component for changing the air circulation effect inside the grain storage room; the movable component includes: movable blades installed on the inner wall of the grain storage room, a fixed rod installed on the outer side of the movable blades, a bevel gear one installed on the surface of the fixed rod, a bevel gear two meshing at the bottom of the bevel gear one, a rotating shaft installed at the bottom of the bevel gear two, a sliding rod slidably connected to the surface of the rotating shaft, an air outlet slot block installed on the surface of the sliding rod, a fixed frame installed inside the grain storage room, the air outlet slot block slidably connected to the inner side of the fixed frame, a telescopic pipe installed on the top of the air outlet slot block, an air guide pipe installed on the top of the telescopic pipe, and the air guide pipe installed on the outside of the duct.

[0007] Preferably, an adjusting blade is rotatably connected to the inner side of the air outlet block, a gear is installed on the outer side of the adjusting blade, a rack meshes with the outer side of the gear, and the rack is installed on the inner side of the fixed frame.

[0008] Preferably, the oscillating assembly includes: a long rod, which is mounted on the outside of the bevel gear, and a striking rod is mounted on the surface of the long rod.

[0009] Preferably, the grain storage room is equipped with a hoisting rope, the bottom of which is fitted with a fixing plate, and the bottom of which is fitted with multiple sets of ribbons.

[0010] Preferably, the surface of the rotating shaft is provided with a reciprocating groove, and the inside of the fixing frame is provided with a groove.

[0011] Preferably, there are two air outlet blocks, and both air outlet blocks are symmetrically arranged with the center line of the fixed frame as the axis of symmetry.

[0012] Preferably, the cross-section of the fixing frame is rectangular, and the width of the fixing frame is consistent with the inner diameter of the grain storage room.

[0013] By employing the above technical solution, this utility model provides a moisture-proof and ventilated structure device for grain storage. It possesses at least the following beneficial effects:

[0014] (1) This utility model, through the setting of movable components, starts the fan, and the airflow also drives the movable blades to rotate, which in turn drives the fixed rod and bevel gear one to rotate. Bevel gear one drives the meshing bevel gear two and the rotating shaft to rotate. The reciprocating slide groove of the rotating shaft drives the slide rod to slide along the slide groove, so that the two symmetrical air outlet blocks move up and down in the fixed frame to realize the adjustment of the air outlet height, adapt to different ventilation needs, and the telescopic pipe extends and retracts synchronously to ensure smooth airflow. When the air outlet blocks move, the gear and rack of the adjusting blade mesh, driving the adjusting blade to change the angle, switch the air outlet direction, prevent ventilation dead angles, improve ventilation uniformity and moisture-proof efficiency, and ensure the quality of grain storage.

[0015] (2) This utility model, through the setting of the swing component, causes the second bevel gear to rotate with the rotating shaft, driving the meshing first bevel gear to rotate, thereby causing the long rod and the striking rod to swing in a circular motion. The striking rod intermittently strikes the airflow, causing the surrounding air to form a vortex, breaking the laminar flow and accelerating air circulation. It will also touch the ribbon, causing it to swing and further disturb the air, preventing local air stagnation. The accelerated airflow can quickly remove moisture from the warehouse, and the moisture is discharged through the duct. Precise air delivery combined with air disturbance reduces uneven humidity in the warehouse, effectively preventing grain from becoming moldy due to local dampness, improving the moisture-proof effect, and reducing the risk of grain damage.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A moisture-proof and ventilation structure for grain storage, such as Figure 1 - Figure 5 As shown, it includes a fan 6 installed on the outside of the grain storage room 1, a duct 2 installed on the top of the fan 6, the duct 2 passing through the left side of the grain storage room 1, and a conduit 3 passing through the right side of the grain storage room 1.

[0027] It also includes an active component 4 for adjusting the air outlet height and angle of the fan 6;

[0028] The swing component 5 is used to change the air circulation effect inside the grain storage room 1.

[0029] First, the movable component 4 includes: a movable blade 41, which is installed on the inner wall of the grain storage room 1; a fixed rod 42 is installed on the outer side of the movable blade 41; a bevel gear 43 is installed on the surface of the fixed rod 42; a bevel gear 44 meshes with the bottom of the bevel gear 43; a rotating shaft 45 is installed at the bottom of the bevel gear 44; a sliding rod 46 is slidably connected to the surface of the rotating shaft 45; an air outlet block 413 is installed on the surface of the sliding rod 46; a fixed frame 47 is installed inside the grain storage room 1; the air outlet block 413 is slidably connected to the inner side of the fixed frame 47; and the top of the air outlet block 413... The unit is equipped with a telescopic pipe 48, and an air guide pipe 49 is installed on the top of the telescopic pipe 48. The air guide pipe 49 is installed on the outside of the air duct 2. It is connected by a rotating shaft 45 and a sliding rod 46, and by an air outlet block 413 and a fixed frame 47. When the rotating shaft 45 rotates, it can drive the sliding rod 46 and the air outlet block 413 to move along a fixed trajectory to ensure stable adjustment of the air outlet height. By using the telescopic pipe 48 to connect the air outlet block 413 and the air guide pipe 49, it can move and extend flexibly with the air outlet block 413, always keeping the airflow delivery channel unobstructed, avoiding airflow leakage, and ensuring ventilation efficiency.

[0030] Secondly, an adjusting blade 410 is rotatably connected to the inner side of the air outlet block 413, and a gear 411 is installed on the outer side of the adjusting blade 410. A rack 412 meshes with the outer side of the gear 411. The rack 412 is installed on the inner side of the fixed frame 47. By "rotatably connecting the adjusting blade 410 with the air outlet block 413", the adjusting blade 410 can freely change its tilt angle, thereby adjusting the air outlet direction.

[0031] In this embodiment, by setting the movable component 4, the fan 6 is started, and the airflow also drives the movable blade 41 to rotate, which in turn drives the fixed rod 42 and the first bevel gear 43 to rotate. The first bevel gear 43 drives the meshing second bevel gear 44 and the rotating shaft 45 to rotate. The reciprocating slide groove 450 of the rotating shaft 45 drives the slide rod 46 to slide along the slide groove 470, so that the two symmetrical air outlet blocks 413 move up and down within the fixed frame 47, realizing the adjustment of the air outlet height to adapt to different ventilation needs. The telescopic pipe 48 extends and retracts synchronously to ensure smooth airflow. When the air outlet blocks 413 move, the gear 411 and the rack 412 of the adjusting blade 410 mesh, driving the adjusting blade 410 to rotate and change the angle, switching the air outlet direction, preventing ventilation dead angles, improving ventilation uniformity and moisture-proof efficiency, and ensuring the quality of grain storage.

[0032] Example 2

[0033] like Figure 6 As shown, the swing assembly 5 includes: a long rod 51, which is mounted on the outside of the bevel gear 43, and a striking rod 52 is mounted on the surface of the long rod 51.

[0034] Furthermore, a suspension rope 53 is installed inside the grain storage room 1, and a fixing plate 54 is installed at the bottom of the suspension rope 53. Multiple sets of ribbons 55 are installed at the bottom of the fixing plate 54. By suspending the fixing plate 54 by the suspension rope 53, the ribbons 55 can be stably arranged in the internal space of the storage room, avoiding the ribbons 55 from affecting grain storage or being crushed by grain due to contact with grain. With the help of multiple sets of ribbons 55 installed at the bottom of the fixing plate 54, the ribbons 55 can swing under the touch of airflow or the striking rod 52, disturbing the laminar flow of air in the storage room, accelerating the mixing of humid air and dry airflow, and improving the efficiency of water vapor discharge.

[0035] Furthermore, a reciprocating groove 450 is provided on the surface of the rotating shaft 45. When the rotating shaft 45 rotates, the reciprocating groove 450 can push the slide rod 46 to move up and down vertically through the groove wall, providing stable reciprocating power for the air outlet block 413, realizing the cyclic adjustment of the air outlet height, covering different height areas in the storage room. A groove 470 is provided inside the fixed frame 47. With the help of the groove 470 inside the fixed frame 47, a directional sliding trajectory is provided for the air outlet block 413, limiting the movement direction of the air outlet block 413, preventing it from deviating or getting stuck during movement, ensuring accurate and stable air outlet height adjustment, and guaranteeing ventilation stability.

[0036] There are two air outlet blocks 413, and both air outlet blocks 413 are symmetrically arranged with the center line of the fixed frame 47 as the axis of symmetry. By "symmetrically arranging the two air outlet blocks 413", airflow can be delivered into the warehouse from both sides of the fixed frame 47 at the same time, so that the airflow is symmetrically distributed in the warehouse, avoiding airflow deviation caused by unilateral air supply and improving the balance of air circulation in the warehouse. At the same time, the design of dual air outlet blocks 413 can increase the airflow output, accelerate the air circulation speed in the warehouse, and shorten the moisture discharge time, which is especially suitable for large grain storage rooms 1, and improves the moisture-proof ventilation efficiency.

[0037] The fixed frame 47 has a rectangular cross-section, and its width is consistent with the inner diameter of the grain storage room 1. By having a rectangular cross-section, the fixed frame 47 can provide a flat and stable sliding support surface for the air outlet block 413, ensuring that the air outlet block 413 is subjected to uniform force when it moves, and reducing component wear. With the fixed frame 47 having a width consistent with the inner diameter of the storage room, the air supply range of the air outlet block 413 can cover the entire transverse section of the storage room, avoiding insufficient airflow coverage on both sides due to the fixed frame 47 being too narrow, eliminating transverse ventilation dead corners, and further improving the comprehensiveness of ventilation coverage.

[0038] In this embodiment, through the setting of the swing component 5, the second bevel gear 44 rotates with the rotating shaft 45, driving the meshing first bevel gear 43 to rotate, thereby causing the long rod 51 and the striking rod 52 to swing in a circular motion. The striking rod 52 intermittently strikes the airflow, causing the surrounding air to form a vortex, breaking the laminar flow and accelerating air circulation. It also touches the ribbon 55, causing it to swing and further disturb the air, preventing local air stagnation. The accelerated airflow can quickly remove moisture from the silo, and the moisture is discharged through the duct 3. Precise air delivery combined with air disturbance reduces uneven humidity in the silo, effectively preventing grain from becoming moldy due to local dampness, improving the moisture-proof effect, and reducing the risk of grain damage.

[0039] In use, the grain storage moisture-proof ventilation structure of this utility model uses the grain storage room 1 as the core carrier. A fan 6 provides ventilation power, and the air duct 2 and guide pipe 3 form an airflow channel. With the help of the movable component 4 to adjust the air outlet height and angle, and the swing component 5 to optimize internal airflow, efficient moisture-proof ventilation is achieved in the storage room. When the device is not started, the fan 6 is in a stopped state, and the air duct 2, guide pipe 49, and telescopic pipe 48 remain connected but no airflow passes through. In the movable component 4, the air outlet slot block 413 is located in the initial position inside the fixed frame 47, the adjusting blade 410 is in a horizontally closed state, and the gear 411 and rack 412 maintain... The initial meshing relationship is maintained; the slide bar 46 is in contact with the surface of the rotating shaft 45, the reciprocating slide groove 450 does not drive the slide bar 46 to move, in the swing assembly 5, the long rod 51 and the striking rod 52 are stationary, the ribbon 55 hangs naturally under the action of gravity, the hanging rope 53 remains in a stretched state, the fixed plate 54 is suspended stably, the duct 3 is in a clear state, providing a channel for the air to be discharged from the storage room, at this time the air in the storage room is in a state of natural circulation, the fan 6 is started, the airflow enters the air guide pipe 49 through the air duct 2, and then is transported to the air outlet block 413 through the telescopic pipe 48, providing the power basis for ventilation. When the airflow enters the air duct 2, it will also drive the rotation of the movable blade 41. When rotated, the fixed rod 42 and bevel gear 43 rotate. When bevel gear 43 rotates, it drives bevel gear 44, which meshes at the bottom, to rotate. When bevel gear 44 rotates, it drives the rotating shaft 45 to rotate. The reciprocating groove 450 on the surface of the rotating shaft 45 drives the slide rod 46 to slide up and down along the groove 470. The slide rod 46 drives the air outlet block 413 to move synchronously inside the fixed frame 47. The two symmetrically arranged air outlet blocks 413 slide smoothly in the vertical direction of the fixed frame 47 to realize the vertical adjustment of the air outlet height, adapting to the ventilation needs of different heights in the storage room. At the same time, the telescopic pipe 48 extends and retracts with the movement of the air outlet block 413 to ensure airflow. The air delivery channel remains unobstructed, and the air outlet angle can be adjusted: When the air outlet block 413 moves, the gear 411 on the outer side of its inner adjusting blade 410 meshes with the rack 412 on the inner side of the fixed frame 47, and the gear 411 drives the adjusting blade 410 to rotate, changing the tilt angle of the adjusting blade 410; by adjusting the angle of the blade 410, the air outlet direction can be flexibly switched, and air can be precisely delivered to different areas in the storage room, avoiding ventilation dead zones, preventing insufficient ventilation in some areas due to fixed ventilation height, and preventing ventilation dead zones caused by a single air outlet angle, thus improving ventilation uniformity, ensuring the quality of grain storage, ensuring ventilation continuity, and improving moisture-proof efficiency.

[0040] When bevel gear 2 44 rotates with shaft 45, bevel gear 1 43, which meshes with bevel gear 2 44, rotates synchronously. Bevel gear 1 43 drives the outer long rod 51 to rotate, and the striking rod 52 on the surface of the long rod 51 swings in a circular motion with the long rod 51. During the swinging process, the striking rod 52 intermittently strikes the airflow in the storage room, while driving the surrounding air to form a vortex, breaking the laminar airflow state and accelerating the air circulation in the storage room. In addition, the swinging of the striking rod 52 will also touch the ribbon 55, causing multiple sets of ribbons 55 to swing under the action of airflow and contact force, further disturbing the air, avoiding local air stagnation, and accelerating the airflow to quickly remove moisture in the storage room. The moisture is discharged outdoors through duct 3 with the airflow. At the same time, the combination of precise air supply and air disturbance can reduce the uneven distribution of humidity in the storage room, effectively prevent the grain from becoming moldy due to local dampness, improve the moisture-proof effect, and reduce the risk of grain damage.
