Description

Technical Field

[0001] This invention relates to the field of grain silo ventilation and grain discharge technology, specifically a multifunctional circular bulk grain silo bottom-mounted ventilation and multi-point grain discharge integrated device. Background Technology

[0002] Shallow round silos have advantages such as low cost per unit volume, reasonable structural stress, high degree of mechanization, large single-silo capacity, small footprint, good airtightness, and strong seismic performance. Therefore, shallow round silos have been widely promoted in China and have played a crucial role in realizing mechanized grain storage.

[0003] Existing shallow circular silos typically have a grain inlet at the center of the roof, through which grain is fed into the silo via a scraper conveyor buried in the roof. A conveyor corridor is installed at the bottom of the silo, with unloading openings along the corridor on the floor. During unloading, the unloading openings are opened, allowing the grain to flow out of the silo by gravity, and then the conveyor in the corridor completes the grain removal process. However, because the silo floor has no or only a small inclination, the removal of remaining grain must be done by a grain unloader or a cleaning auger. This increases the difficulty of unloading grain to some extent.

[0004] In order to improve grain discharge efficiency and reduce discharge costs without reducing the level of mechanization of shallow round silos, most shallow round silos currently use grain unloaders or augers to clean the remaining grain at the bottom of the silo after discharge. However, the above methods of cleaning the remaining grain at the bottom of the silo still have some problems that need to be solved, which limits the grain discharge efficiency of shallow round silos to a certain extent. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional integrated device for multi-point grain discharge with ventilation at the bottom of a circular bulk grain silo, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multifunctional circular bulk grain silo bottom-mounted ventilation multi-point grain discharge integrated device is symmetrically semi-elliptical in shape, including a top plate and a bottom plate connected to the top plate, and a reinforcing structure is provided between the top plate and the bottom plate. The top plate and the bottom plate are provided with rectangular holes above the ventilation corridor at the bottom of the silo, and the rectangular holes are adapted to the ventilation corridor at the bottom of the silo. The bottom of the silo is also adapted to a material discharge auxiliary structure. The reinforcing structure includes radial partitions and vertical partitions disposed between the top plate and the bottom plate. The height of the vertical partitions gradually increases from the center of the storage area to the storage wall. The vertical partitions and the radial partitions are welded together to form a grid-shaped configuration.

[0007] As a further aspect of the present invention: the radial partition and the vertical partition are welded together to form an integral whole, and their top surface has a certain angle with the bottom of the grain silo, the angle being θ, and 0°≤θ≤60°.

[0008] As a further embodiment of the present invention: corbels are arranged along the length of the partitions on both sides of the ventilation corridor. The top elevation of the corbels is lower than the top plate by a certain height and is equal to the bottom elevation of the buckle plate. They are made of plastic or steel plate. The elevation of the buckle plate is equal to the elevation of the top plate at the corresponding position. The size of the angle steel embedded in the upper edge of the ventilation corridor is equal.

[0009] As a further embodiment of the present invention: the discharge auxiliary structure includes a discharge pipe assembly located at the bottom of the bin, the discharge pipe assembly including a connector fixed to the bottom of the bin, an intermediate pipe connected to the connector through two sets of elastic locking mechanisms, an adapter connected to the intermediate pipe in a sealed rotatable manner, and a movable pipe connected to the adapter through a telescopic hose. The movable pipe fitting is rotatably connected to the adapter, and the rotation axis of the movable pipe fitting is perpendicular to its own central axis. A disc is fixed on the intermediate pipe, and a power mechanism is installed on the disc. The power mechanism is connected to the adapter and can drive the adapter to rotate the movable pipe. The adapter is fixedly connected to a mounting bracket, and a sliding fit mechanism is installed on the mounting bracket. The sliding fit mechanism is connected to a transmission mechanism. The transmission mechanism is triggered during the rotation of the adapter and can cause the sliding fit mechanism to drive the movable pipe to swing back and forth, thereby increasing the discharge range of the movable pipe.

[0010] As a further embodiment of the present invention: the power mechanism includes a drive motor mounted on the disc body, a first gear fixed on the output shaft of the drive motor, and a first gear ring fixedly mounted on the adapter, wherein the first gear meshes with teeth provided on the outer wall of the first gear ring.

[0011] As a further embodiment of the present invention: the sliding fit mechanism includes an assembly plate rotatably mounted on the mounting bracket and a column movably disposed on the assembly plate. The column is connected to a threaded adjustment assembly mounted on the assembly plate. The threaded adjustment assembly can drive the column to move along the length direction of the assembly plate, and the rotation axis of the assembly plate is connected to the transmission mechanism. The movable pipe has a strip-shaped protrusion on its outer wall, and a groove is provided on the strip-shaped protrusion. The column extends into the groove and is slidably connected to the strip-shaped protrusion.

[0012] As a further embodiment of the present invention: the threaded adjustment assembly includes a lead screw rotatably mounted on the assembly plate, a slider slidably disposed on the assembly plate and fixedly connected to the column, a protrusion fixed on the slider, the lead screw passing through the protrusion and threadedly connected thereto, and the lead screw also being connected to a knob rotatably disposed on the assembly plate via a first bevel gear set.

[0013] As a further embodiment of the present invention: the transmission mechanism includes a transmission shaft rotatably mounted on the mounting bracket, a second gear fixedly mounted on one end of the transmission shaft, and a second gear ring fixed to the bottom of the disc body. The second gear meshes with the teeth on the inner wall of the second gear ring, and the other end of the transmission shaft is connected to the rotation shaft of the mounting plate through the second bevel gear set.

[0014] As a further embodiment of the present invention: the end of the connector facing the intermediate pipe is formed with a tapered surface, and the connector is also provided with two locking holes respectively adapted to the two sets of elastic locking mechanisms; The elastic locking mechanism includes a guide cylinder fixed to the intermediate pipe via a connecting arm, a locking rod slidably fitted with the guide cylinder, and a cylindrical spring disposed inside the guide cylinder. One end of the cylindrical spring is connected to the inner wall of the guide cylinder, and the other end is connected to the locking rod. The locking rod is adapted to the lock hole, and a ball bearing is provided at the end of the locking rod located outside the guide cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The present invention has a novel design: 1. The top plate has a smooth surface, resulting in less friction with the grain particles, allowing the grain particles to slide down under their own weight and be discharged through the outlet. 2. The vertical partitions are fixed to the top plate and radial partitions by welding. The vertical partitions position the entire device relative to the bottom plane of the silo. 3. The radial and vertical partitions are welded together to form a cross-grid structure, making the interior of the entire device open space, which saves materials, speeds up the overall construction, and further shortens the construction period. 4. The partitions and top plates of the device can be produced in a standardized manner in the factory, which can effectively control the quality of processing and manufacturing while being energy-saving and environmentally friendly; the prefabricated products are assembled on site, which greatly reduces the intensity of on-site construction. At the same time, the degree of mechanization increases, reducing the number of on-site personnel and saving labor costs. Cross-installation construction can be carried out, shortening the construction period. 5. From the center of the warehouse towards the warehouse wall, the height of the radial and vertical partitions gradually increases. The angle between the top plate of the device and the bottom plane of the warehouse is θ, 0°≤θ≤60°. The angle is different for storing different types of grain, which is convenient for the use of grain warehouses that store various types of grain. 6. Brackets are installed on both sides of the ventilation corridor, vertically aligned with the edge of the ventilation corridor. The arrangement of these brackets elevates the entire air duct used for mechanical ventilation without altering the original airflow path of the mechanical ventilation corridor, ensuring the normal operation of mechanical ventilation throughout the entire grain storage process. 7. The top plate of the device is made of plastic or steel plate, and is a semi-elliptical surface. The intersection of the inner side of the top plate and the vertical partition is welded. The surface of the semi-elliptical top plate is smooth, and the angle formed between it and the bottom plane meets the requirements for grain self-flowing. The lower part of the semi-elliptical top plate is supported by a mesh structure composed of vertical plastic plates and radial partitions. This structure integrates the top plate, vertical partitions, and radial partitions into a whole, making the stress on the top plate more reasonable. Moreover, the components of the device are prefabricated blocks, which improves the assembly rate of the structure, reduces bottom construction work, and makes construction simpler and faster.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0035] Please see Figures 1-6 In this embodiment of the invention, a multifunctional circular bulk grain silo bottom-mounted ventilation multi-point grain discharge integrated device is arranged in a symmetrical semi-elliptical shape, including a top plate 1 and a bottom plate 5 connected to the top plate 1, and a reinforcing structure is provided between the top plate 1 and the bottom plate 5. The top plate 1 and the bottom plate 5 are both provided with rectangular holes above the bottom ventilation corridor 9, and the rectangular holes are adapted to the bottom ventilation corridor 9. The bottom of the silo is also adapted to a discharge auxiliary structure.

[0036] The reinforcing structure includes a radial partition 2 and a vertical partition 3 disposed between the top plate 1 and the bottom plate 5. The height of the vertical partition 3 gradually increases from the center of the warehouse to the warehouse wall. The vertical partition 3 and the radial partition 2 are welded together to form a grid-shaped configuration.

[0037] Furthermore, the vertical partition 3 is made of plastic or steel plate, and is fixed to the top plate 1 and the radial partition 2 by welding. The height of the vertical partition 3 depends on the height of the top plate 1 of the grain discharging device. Simultaneously, the height of the vertical partition 3 gradually increases from the center of the silo to the silo wall. The vertical partition 3 and the radial partition 2 are interwoven and welded to form a grid-like structure, thus creating a support with a certain angle, providing a foundation for the construction of the inclined top plate. Secondly, the bottom plate 5 is raised relative to the bottom surface of the vertical partition 3. The purpose of raising it is to prevent the bottom plate 5 from warping due to unevenness of the supporting surface when it is placed. Thus, the top plate 1, the radial partition 2, the vertical partition 3, and the bottom plate 5 form a whole, constituting the load-bearing structure of the entire grain dispensing device, and also the frame of the entire device.

[0038] Furthermore, the partitions 15 on both sides of the ventilation corridor are made of plastic or steel plate and are arranged along both sides of the ventilation corridor 9. The height of the partitions 15 on both sides of the ventilation corridor is determined by layout, and their thickness is greater than that of the radial partition 2. The specific thickness is calculated based on the dimensions of the ventilation corridor 9, while ensuring that the distance between the corresponding brackets 11 between the partitions 15 on both sides of the two ventilation corridors is equal to the designed width of the ventilation corridor 9. The brackets 11 are made of plastic or steel plate and are welded along their entire length to a certain position above the partitions 15 on both sides of the ventilation corridor. The top elevation of the brackets 11 is lower than that of the top plate 1 by a certain height and is equal to the bottom elevation of the buckle plate 10. They mainly bear the pressure from the brackets 11, enabling the brackets 11 to withstand the grain pressure from the air device in the ventilation trough, thereby maintaining the structural stability of the entire equipment.

[0039] The buckle plate 10 is mainly used to prevent it from sliding down the ventilation corridor 9 to the bottom of the warehouse; The top plate 1, the bottom plate 5, the radial partition 2 and the vertical partition 3 are welded together to form an integral whole. The top surface of the partition is at a certain angle to the bottom of the grain silo, with the angle being θ, and 0°≤θ≤60°.

[0040] In actual implementation, the bottom of the silo is provided with a reinforced concrete silo bottom 13, and an underground corridor 7 is formed inside the silo. The silo wall is a concrete silo wall 4, and the discharge auxiliary structure is adapted to the grain outlet 6.

[0041] Please see Figures 14-16 Embodiment 2 of the present invention provides a multifunctional circular bulk grain silo bottom-mounted ventilation multi-point grain discharge integrated device. Unlike Embodiment 1 of the present invention, the diameter and height of the circumferential partition 12 gradually increase from the center of the silo to the silo wall. The circumferential partition 12 and the radial partition 2 are interwoven and welded to each other to form a grid-shaped configuration.

[0042] Furthermore, the circumferential partition 12 is made of plastic or steel plate, and is fixed to the top plate 1 and the radial partition 2 by welding. The height of the circumferential partition 12 depends on the height of the top plate 1 of the grain discharging device. Simultaneously, the diameter and height of the circumferential partition 12 gradually increase from the center of the silo to the silo wall. The circumferential partition 12 and the radial partition 2 are interwoven and welded to form a grid-like configuration, thus creating a support at a certain angle, providing a foundation for the construction of the inclined surface of the top plate. Furthermore, the radial partitions 2 are arranged radially. At the end closest to the silo wall, the intersection point with the silo wall is recorded as the intersection point. The angle between the two straight lines connecting two adjacent intersection points and the center of the grain silo plan is α, and 4°≤a≤10°. At the end of the radial partition closest to the center of the grain silo, it intersects with the edge of the grain discharge system. The extension lines of all radial partitions intersect with the center of the grain silo plan.

[0043] The top plate 1, the radial partition 2, the circumferential partition 12, and the bottom plate 5 form a whole, constituting the load-bearing structure of the entire grain discharging device, and also the frame of the entire device.

[0044] In summary, the beneficial effects of the present invention are as follows: 1. The surface of the top plate 1 is smooth, and the friction between it and the grain particles is small, so that the grain particles can slide down by their own weight and be discharged through the grain outlet. 2. The vertical partition 3 is fixed to the top plate 1 and the radial partition 2 by welding, and the circumferential partition positions the entire device relative to the bottom plane of the silo. 3. The radial partition 2 and the vertical partition 3 are welded together to form a cross-grid structure, making the interior of the entire device open space, which saves materials, speeds up the overall construction speed, and further shortens the construction period. 4. The partitions and top plates of the device can be produced in a standardized manner in the factory, which can effectively control the quality of processing and manufacturing while being energy-saving and environmentally friendly; the prefabricated products are assembled on site, which greatly reduces the intensity of on-site construction. At the same time, the degree of mechanization increases, reducing the number of on-site personnel and saving labor costs. Cross-installation construction can be carried out, shortening the construction period. 5. From the center of the warehouse towards the warehouse wall, the height of the radial and vertical partitions gradually increases. The angle between the top plate of the device and the bottom plane of the warehouse is θ, 0°≤θ≤60°. The angle is different for storing different types of grain, which is convenient for the use of grain warehouses that store various types of grain. 6. Brackets are installed on both sides of the ventilation corridor, vertically aligned with the edge of the ventilation corridor. The arrangement of these brackets elevates the entire air unit used for mechanical ventilation without altering the original airflow path of the mechanical ventilation corridor, ensuring the normal operation of mechanical ventilation throughout the entire grain storage process. 7. The top plate of the device is made of plastic or steel plate, and is semi-elliptical. The intersection of the inner side of the top plate and the vertical partition is welded. The surface of the semi-elliptical top plate is smooth, and the angle formed between it and the bottom plane meets the requirements for grain self-flowing. The lower part of the semi-elliptical top plate is supported by a mesh structure composed of circumferential plastic plates and radial partitions. This structure integrates the top plate, vertical partitions, and radial partitions into a whole, making the stress on the plastic top plate more reasonable. Moreover, the components of the device are prefabricated blocks, which improves the assembly rate of the structure, reduces bottom construction work, and makes construction simpler and faster.

[0045] Please refer to it again. Figures 8-14 The discharge auxiliary structure includes a discharge pipe assembly located at the bottom of the bin. The discharge pipe assembly includes a connector 16 fixed to the bottom of the bin, an intermediate pipe 17 connected to the connector 16 via two sets of elastic locking mechanisms, an adapter 18 sealed and rotatably connected to the intermediate pipe 17, and a movable pipe 20 connected to the adapter 18 via a telescopic hose 19. The movable pipe fitting 20 is rotatably connected to the adapter 18, and the rotation axis of the movable pipe fitting 20 is perpendicular to its own central axis. A disc 21 is fixed on the intermediate pipe 17, and a power mechanism is installed on the disc 21. The power mechanism is connected to the adapter 18 and can drive the adapter 18 to rotate the movable pipe 20. The adapter 18 is fixedly connected to a mounting bracket 40, and a sliding engagement mechanism is installed on the mounting bracket 40. The sliding engagement mechanism is connected to a transmission mechanism. The transmission mechanism is triggered during the rotation of the adapter 18 and can cause the sliding engagement mechanism to drive the movable pipe 20 to swing back and forth, so as to increase the discharge range of the movable pipe 20.

[0046] In practical implementation, before material feeding, the intermediate pipe 17 can be assembled with the connector 16 through the elastic locking mechanism. Subsequently, the power mechanism works to drive the adapter 18 to rotate. At the same time, the mounting bracket 40 performs a circular motion, which triggers the transmission mechanism. The transmission mechanism then drives the sliding engagement mechanism to move, which in turn drives the movable pipe 20 to reciprocate. Ultimately, the circular motion and reciprocating swing of the movable pipe 20 are synchronized, effectively improving the material feeding range to meet different material feeding requirements.

[0047] Please refer to it again. Figure 9 and Figure 10 The power mechanism includes a drive motor 33 mounted on the disc body 21, a first gear 34 fixed on the output shaft of the drive motor 33, and a first gear ring 35 fixed on the adapter 18. The first gear 34 meshes with teeth provided on the outer wall of the first gear ring 35.

[0048] When the material is being fed, the drive motor 33 operates, which drives the first gear 34 to rotate. The first gear 34 then drives the first gear ring 35 to rotate the adapter 18. Correspondingly, the adapter 18 drives the movable tube 20 to rotate.

[0049] Please refer to it again. Figure 11 and Figure 13 The sliding fit mechanism includes an assembly plate 26 rotatably mounted on the mounting bracket 40 and a column 27 movably disposed on the assembly plate 26. The column 27 is connected to a threaded adjustment assembly mounted on the assembly plate 26. The threaded adjustment assembly can drive the column 27 to move along the length direction of the assembly plate 26, and the rotation axis of the assembly plate 26 is connected to the transmission mechanism. The movable tube 20 has a strip-shaped protrusion 28 on its outer wall, and the strip-shaped protrusion 28 is provided with a sliding groove. The column 27 extends into the sliding groove and is slidably connected to the strip-shaped protrusion 28.

[0050] The threaded adjustment assembly includes a lead screw 29 rotatably mounted on the assembly plate 26, a slider 30 slidably disposed on the assembly plate 26 and fixedly connected to the column 27, a protrusion 3001 fixed on the slider 30, the lead screw 29 passing through the protrusion 3001 and threadedly connected thereto, and the lead screw 29 is also connected to a knob 32 rotatably disposed on the assembly plate 26 through a first bevel gear set 31.

[0051] When the transmission mechanism is triggered, it can drive the assembly plate 26 to rotate. Then, the assembly plate 26 will drive the column 27 to perform a circular motion. Correspondingly, the column 27 will slide and engage with the strip protrusion 28 through the slide groove, thereby causing the movable tube 20 to perform a reciprocating swinging motion. When faced with different material feeding requirements, before starting the drive motor 33, the operator can turn the knob 32. Then, the knob 32 will drive the lead screw 29 to rotate through the first bevel gear set 31. The protrusion 3001 will engage with the lead screw 29 and drive the slider 30 and the column 27 to move along the length of the assembly plate 26. The greater the distance between the column 27 and the rotation axis of the assembly plate 26, the larger the radius of the circular motion of the column 27, resulting in a larger swing amplitude of the movable tube 20 and a wider discharge range. Conversely, the smaller the distance between the column 27 and the rotation axis of the assembly plate 26, the smaller the radius of the circular motion of the column 27, resulting in a smaller swing amplitude of the movable tube 20 and a smaller discharge range.

[0052] Please refer to it again. Figure 8 , Figure 9 as well as Figure 11 The transmission mechanism includes a transmission shaft 38 rotatably mounted on the mounting bracket 40, a second gear 36 fixedly mounted on one end of the transmission shaft 38, and a second gear ring 37 fixed to the bottom of the disc body 21. The second gear 36 meshes with the teeth on the inner wall of the second gear ring 37, and the other end of the transmission shaft 38 is connected to the rotation shaft of the mounting plate 26 through the second bevel gear set 39.

[0053] In detail, the first bevel gear group 31 includes a first bevel gear fixed coaxially with the knob 32 and a second bevel gear fixedly installed on the end of the lead screw 29 facing the knob 32, the second bevel gear meshing with the first bevel gear; Similarly, the second bevel gear set 39 includes a third bevel gear fixedly installed on the end of the transmission shaft 38 away from the second gear 36 and a fourth bevel gear fixedly installed on the rotating shaft of the mounting plate 26, the fourth bevel gear meshing with the third bevel gear.

[0054] Please refer to it again. Figure 12 and Figure 14 The connector 16 has a tapered surface 1601 at one end facing the intermediate pipe 17, and the connector 16 is also provided with two locking holes 1602 that are respectively adapted to the two sets of elastic locking mechanisms. The elastic locking mechanism includes a guide cylinder 24 fixed to the intermediate pipe 17 via a connecting arm 22, a locking rod 25 slidably fitted with the guide cylinder 24, and a cylindrical spring 23 disposed inside the guide cylinder 24. One end of the cylindrical spring 23 is connected to the inner wall of the guide cylinder 24, and the other end is connected to the locking rod 25. The locking rod 25 is adapted to the lock hole 1602, and a ball bearing is provided at one end of the locking rod 25 located outside the guide cylinder 24.

[0055] In actual use, the operator can align the intermediate pipe 17 with the connector 16, and then push the intermediate pipe 17 toward the connector 16. During this process, the ball is released from the tapered surface 1601, causing the locking rod 25 to retract. Specifically, the locking rod 25 retracts into the guide cylinder 24, and the cylindrical spring 23 is compressed. After the ball is flush with the locking hole 1602, the operator twists the intermediate pipe 17 until the ball is aligned with the locking hole 1602. Then, the cylindrical spring 23 rebounds, causing the locking rod 25 to insert into the locking hole 1602, thus achieving rapid assembly of the intermediate pipe 17 and the connector 16.
