Description

Technical Field

[0001] The invention relates to the technical field of grain silo ventilation and grain discharging, and in particular to a multifunctional circular bulk grain silo bottom assembled full-ventilation multi-point grain discharging integrated device. Background Art

[0002] Shallow silos have the advantages of low unit volume cost, reasonable structural force, high degree of mechanization, large single-silo capacity, small footprint, good airtightness, strong earthquake resistance, etc. Therefore, shallow silos have been vigorously promoted in China and have played a vital role in realizing the mechanized storage of grain.

[0003] The existing shallow round silos generally have a grain inlet at the center of the silo roof, and the grain is fed into the silo through the scraper conveyor buried in the silo roof. A conveying corridor is set at the bottom of the silo, and a grain unloading port is opened on the floor of the silo along the direction of the corridor. When unloading grain, the grain unloading port is opened, and the grain flows out of the silo by itself, and then the grain unloading operation is completed by the conveyor in the corridor. However, since the silo bottom plane has no inclination or a small inclination, the clearing operation of the remaining grain in the silo needs to be completed by a grain scraper or a silo clearing auger. This increases the difficulty of unloading grain to a certain extent.

[0004] In order to improve grain discharge efficiency and reduce grain discharge costs without reducing the mechanization level of shallow silos, most shallow silos currently use grain scrapers or silo-cleaning auger to clean up the remaining grain at the bottom of the silo after discharge. However, the above-mentioned method of cleaning the remaining grain at the bottom of the silo still has some problems that need to be solved, which limits the grain discharge efficiency of shallow silos to a certain extent.

[0005] In order to take into account the convenience of grain delivery during the transfer and storage process, the existing shallow silos in my country mostly adopt the ground trough ventilation system. The general air duct layout includes radial, circular, comb-shaped, plum-shaped, F-shaped ducts, etc. However, during use, there are still problems such as small air outlet surface, large ventilation resistance, poor cooling effect and ventilation dead corners. Under the condition of multiple fans working together, the ventilation effect is not significantly improved. Summary of the invention

[0049] See also Figure 1-Figure 5 In the embodiment of the present invention, a multifunctional circular bulk grain silo bottom assembled full ventilation grain discharge integrated device is arranged in a semi-elliptical shape, including a top plate 1 and a bottom plate 5 connected to the top plate 1, and a consolidation structure and a full ventilation system are arranged between the top plate 1 and the bottom plate 5, and the silo bottom is also adapted to be equipped with a discharge auxiliary structure;

[0050] The top plate 1 is a frame structure, the smallest unit is a quadrilateral area surrounded by two adjacent radial partitions 2 and vertical beams 3, and a sieve plate 12 is laid on the top plate 1, and the sieve plate 12 is adapted to the smallest unit of the top plate 1.

[0051] The consolidation structure includes radial partitions 2 and vertical beams 3 arranged between the top plate 1 and the bottom plate 5. The height of the radial partitions 2 gradually increases from the center of the warehouse to the warehouse wall. The vertical beams 3 and the radial partitions 2 are cross-welded to each other to form a grid-shaped configuration.

[0052] Furthermore, the radial partition 2 is made of plastic or steel plate, the upper part of the radial partition 2 is grooved and vertical beams 3 are arranged throughout the length, and corbels 13 are arranged at the upper non-grooved parts on both sides of the radial partition 2, and the top elevation of the corbels 13 is equal to the bottom elevation of the top plate 1.

[0053] Furthermore, the vertical beam 3 is made of plastic plate or steel plate. The vertical beam 3 is arranged throughout the length of the slotted position above the radial partition 2. The vertical beam 3 is fixed to the top plate 1 and the radial partition 2 by welding. The height of the vertical beam 3 depends on the height of the semi-elliptical top plate 1 of the grain discharge device. At the same time, the height of the radial partition 2 gradually increases from the center of the warehouse to the warehouse wall. The vertical beam 3 and the radial partition 2 are cross-welded to each other to form a grid-shaped configuration, so that a support with a certain angle is formed, which provides a basis for the construction of the top plate slope; at this point, the top plate 1, the radial partition 2, the vertical beam 3, the circumferential partition 1401 and the bottom plate 5 form a whole, which constitutes the force-bearing structure of the entire grain discharge device, and is also the frame of the entire device.

[0054] Secondly, the corbels 13 are made of plastic or steel plate and are welded to a certain position above both sides of the radial partition 2. The top elevation of the corbels 13 is equal to the height of the top plate 1. The radial partition 2 mainly bears the pressure from the corbels 13, so that the corbels 13 can withstand the grain pressure from the top plate 1. Thus, the structural stability of the entire equipment is maintained.

[0055] In addition, the top plate 1 is made of cast iron or steel plate and is installed on the radial partitions 2 via a fixing device 15 . The corbels 13 between the radial partitions 2 provide support for the installation of the top plate 1 .

[0056] The sieve plate 12 is made of stainless steel, and is fully spread and fixed on the top plate 1. The opening rate of the sieve plate 12 is 30%, and the size of the opening is limited to be smaller than the minimum particle size of the stored grains.

[0057] The bottom plate 5, the radial partition plate 2, the circumferential partition plate 1401 and the vertical beam 3 are welded to form a whole, and a top surface thereof has a certain angle with the bottom of the granary, the angle is θ, and 0°≤θ≤60°.

[0058] In actual implementation, the silo wall is a concrete silo wall 4 , the auxiliary discharge structure is adapted to the grain discharge port 6 , and the silo bottom is a reinforced concrete surface 9 .

[0059] See also Figure 1 , Figure 3-Figure 5 and Fig.13 Embodiment 2 of the present invention is a multifunctional circular bulk grain silo bottom-assembled fully ventilated multi-point grain discharge integrated device. Different from embodiment 1 of the present invention, the diameter of the circumferential beam 1402 gradually increases from the silo center to the silo wall, and the circumferential beam 1402 and the radial partition 2 are cross-welded to each other to form a grid-shaped configuration.

[0060] Specifically, the circumferential beam 1402 is made of a plastic plate or a steel plate, and the circumferential beam 1402 is fixed to the top plate 1, the radial partition 2, and the circumferential partition 1401 by welding. At the same time, the diameter of the circumferential beam 1402 gradually increases from the center of the bin to the bin wall. The circumferential beam 1402 and the radial partition 2 are cross-welded to form a grid-shaped configuration, so that a support with a certain angle is formed, which provides a basis for the construction of the top plate slope;

[0061] Furthermore, the radial partitions 2 are arranged radially, and the intersection with the silo wall at one end close to the silo wall is recorded as the intersection point. The angle between the two straight lines connecting the two adjacent intersection points and the center of the silo plan is a, and 4°≤a≤10°. The end of the radial partition close to the center of the silo intersects with the edge of the grain discharge system, and all the extended lines of the radial partitions intersect at the center of the silo plan.

[0062] The top plate 1, the radial partition plate 2, the circumferential beam 1402, the circumferential partition plate 1401 and the bottom plate 5 form a whole, constitute the force-bearing structure of the entire grain discharge device, and also serve as the frame of the entire device.

[0063] In summary, the beneficial effects of the present invention are as follows:

[0064] 1. The surface of the top plate is smooth, and the friction between the top plate and the grain particles is small, so that the grain particles can slide down by their own gravity and be discharged through the grain outlet;

[0065] 2. The ventilation system is arranged between radial partitions to form a full ventilation system, eliminating the original air duct setting and making the mechanical ventilation process faster and more effective.

[0066] 3. The vertical beams and vertical partitions are fixed by welding, and the radial partitions position the entire device and the bottom plane of the silo;

[0067] 4. The radial partitions and vertical beams are welded to each other to form a cross grid structure, so that the interior of the entire device is in the form of a space, which saves materials, speeds up the overall construction speed, and further shortens the construction period;

[0068] 5. The partitions and top plates of the device can be produced in a standardized manner in the factory, and the processing and manufacturing quality can be effectively controlled and 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 is increased, the number of on-site personnel is reduced, the labor cost is saved, and the cross-installation construction can be carried out, shortening the construction period;

[0069] 6. From the center of the silo to the silo wall, the height of the radial partition and the diameter of the vertical beam gradually increase. The angle between the top plate of the device and the plane of the silo bottom is θ, 0°≤θ≤60°. For different types of grain, the angle is different, which is convenient for storing various types of grain in silos;

[0070] 7. Grooves are made above the radial partitions and vertical beams are arranged throughout the length. Corbels are arranged above both sides of the radial partitions without grooves. The top elevation of the corbels is equal to the bottom elevation of the top plate. Through the arrangement of the corbels, the air device used for mechanical ventilation is raised as a whole, without changing the air flow path of the original mechanical ventilation corridor, thus ensuring the normal use of mechanical ventilation in the entire grain storage process.

[0071] 8. The top plate of the device is made of cast iron or steel plate. The top plate is a semi-elliptical surface, which is installed on the radial partition through a fixing device. The surface of the semi-elliptical top plate is smooth, and the angle between it and the plane of the bottom of the silo meets the requirements for the self-flow of grain. The lower part of the semi-elliptical top plate is supported by a mesh structure composed of vertical beams and radial partitions. On the one hand, the top plate, vertical beams, radial partitions and circumferential partitions form a whole, making the top plate more reasonably stressed. In addition, the components of the device are prefabricated blocks, which improves the assembly rate of the structure, reduces the construction of the bottom of the silo, and makes the construction simpler and faster.

[0072] Please refer again Figure 6-Figure 12 The auxiliary discharge structure includes a discharge pipe group arranged at the bottom of the bin, and the discharge pipe group includes a connector 16 fixed to the bottom of the bin, an intermediate pipe 17 connected to the connector 16 through 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 through a telescopic hose 19;

[0073] The movable tube 20 is rotatably connected to the adapter 18, and the rotation axis of the movable tube 20 is perpendicular to its own central axis;

[0074] 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 drive the movable pipe 20 to rotate. The adapter 18 is fixedly connected to a mounting frame 40, and a sliding fit mechanism is installed on the mounting frame 40. The sliding fit mechanism is connected to a transmission mechanism. The transmission mechanism is triggered during the rotation of the adapter 18, and can prompt the sliding fit mechanism to drive the movable pipe 20 to swing back and forth, so as to increase the discharge range of the movable pipe 20.

[0075] In specific implementation, before unloading, the intermediate pipe 17 can be assembled with the connecting head 16 through the elastic locking mechanism, and then the power mechanism works to drive the adapter 18 to rotate. At the same time, the mounting frame 40 makes a circular motion and triggers the transmission mechanism, so that the transmission mechanism drives the sliding matching mechanism to move, and the sliding matching mechanism drives the movable pipe 20 to swing back and forth. Finally, the circular motion and reciprocating swing of the movable pipe 20 are performed synchronously, which effectively improves the unloading range to meet different unloading requirements.

[0076] Please refer again Figure 7 and Figure 8 The power mechanism includes a driving motor 33 mounted on the disk body 21, a first gear 34 fixed on the output shaft of the driving motor 33, and a first gear ring 35 fixedly mounted on the adapter 18, and the first gear 34 is meshed with teeth provided on the outer wall of the first gear ring 35.

[0077] When unloading, the driving motor 33 works to drive the first gear 34 to rotate, so that the first gear 34 can drive the first gear ring 35 to drive the adapter 18 to rotate, and correspondingly, the adapter 18 can drive the movable pipe 20 to rotate.

[0078] Please refer again Fig. 9 and Fig.11 The sliding fit mechanism includes an assembly plate 26 rotatably mounted on the mounting frame 40 and a column 27 movably mounted on the assembly plate 26, wherein the column 27 is connected to a threaded adjustment assembly mounted on the assembly plate 26, and 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;

[0079] A strip-shaped protrusion 28 is formed on the outer wall of the movable tube 20 , and a sliding groove is provided on the strip-shaped protrusion 28 . The column 27 extends into the sliding groove and is slidably connected with the strip-shaped protrusion 28 .

[0080] 8. The threaded adjustment assembly includes a screw rod 29 rotatably mounted on the assembly plate 26, a slider 30 slidably set on the assembly plate 26 and fixedly connected to the column 27, a protrusion 3001 is fixed on the slider 30, the screw rod 29 passes through the protrusion 3001 and is threadedly connected thereto, and the screw rod 29 is also connected to a knob 32 rotatably set on the assembly plate 26 through a first bevel gear set 31.

[0081] When the transmission mechanism is triggered, it can drive the assembly plate 26 to rotate, so that the assembly plate 26 drives the column 27 to perform a circular motion. Correspondingly, the column 27 will slide and cooperate with the strip-shaped protrusion 28 through the sliding groove, thereby prompting the movable pipe 20 to perform a reciprocating swinging motion;

[0082] When facing different material unloading requirements, before starting the driving motor 33, the staff can rotate the knob 32, and then the knob 32 will drive the screw rod 29 to rotate through the first bevel gear set 31, and the protrusion 3001 will be threadedly matched with the screw rod 29 and drive the slider 30 and the column 27 to move along the length direction of the assembly plate 26;

[0083] The greater the distance between the column 27 and the rotation axis of the assembly plate 26, the greater the trajectory radius of the subsequent circular motion of the column 27, thereby, the greater the swing amplitude of the movable tube 20, and the wider the discharge range. On the contrary, the smaller the distance between the column 27 and the rotation axis of the assembly plate 26, the smaller the trajectory radius of the subsequent circular motion of the column 27, thereby, the smaller the swing amplitude of the movable tube 20, and the smaller the discharge range.

[0084] Please refer again Figure 6 , Figure 7 as well as Fig. 9 The transmission mechanism includes a transmission shaft 38 rotatably mounted on the mounting frame 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 disk 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 rotating shaft of the assembly plate 26 through the second bevel gear set 39.

[0085] In detail, the first bevel gear 31 group includes a first bevel gear coaxially fixed with the knob 32 and a second bevel gear fixedly mounted on the end of the screw rod 29 facing the knob 32, and the second bevel gear meshes with the first bevel gear;

[0086] Similarly, the second bevel gear set 39 includes a number three bevel gear fixedly mounted on the end of the transmission shaft 38 away from the second gear 36 and a number four bevel gear fixedly mounted on the rotating shaft of the assembly plate 26, and the number four bevel gear meshes with the number three bevel gear.

[0087] Please refer again Fig.10 and Fig.12 The connector 16 has a conical surface 1601 formed on one end thereof facing the intermediate pipe 17, and the connector 16 is also provided with two locking holes 1602 respectively adapted to the two sets of elastic locking mechanisms;

[0088] The elastic locking mechanism includes a guide cylinder 24 fixed to the intermediate pipe 17 through a connecting arm 22, a locking rod 25 slidably fitted with the guide cylinder 24, and a cylindrical spring 23 arranged in 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 locking hole 1602, and a ball is provided at one end of the locking rod 25 located outside the guide cylinder 24.

[0089] In actual use, the staff can align the intermediate pipe 17 with the connecting head 16, and then push the intermediate pipe 17 toward the connecting head 16. During this process, the ball and the conical surface 1601 are released, causing the locking rod 25 to give way. 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 staff twists the intermediate pipe 17 until the ball is aligned with the locking hole 1602. Then, the cylindrical spring 23 rebounds, allowing the locking rod 25 to be inserted into the locking hole 1602, thereby achieving rapid assembly of the intermediate pipe 17 and the connecting head 16.
