Description

Technical Field

[0001] This invention belongs to the field of silo technology, specifically relating to silos with easily adjustable diameters, and also to methods for adjusting the diameter of silos. Background Technology

[0002] Silos are storage facilities used to store bulk materials and are widely used in agriculture, mining, construction, and other fields. Currently, most traditional silo structures are fixed-diameter monolithic structures. Once built, their diameter cannot be adjusted, preventing flexible changes in storage space based on the amount of material to be stored. Furthermore, monolithic structures have long construction cycles. When the amount of material to be stored is small, this results in wasted silo space; when the amount of material to be stored is large, additional silos need to be built, increasing costs and floor space requirements.

[0003] Existing adjustable-diameter silo structures suffer from complex adjustment methods and poor structural stability, making them unsuitable for practical applications. Therefore, there is an urgent need for a silo structure that allows for convenient diameter adjustment and offers structural stability. Summary of the Invention

[0004] The purpose of this invention is to provide a silo with an easily adjustable diameter, solving the problems of complex diameter adjustment methods and poor structural stability in existing silo systems.

[0005] Another object of the present invention is to provide a method for adjusting the diameter of a silo.

[0006] The technical solution adopted in this invention is a silo with an easily adjustable diameter, including a silo top frame. Several silo top inclined columns are connected to the side wall of the silo top frame along its circumference. A silo top main beam is slidably connected to the end of each silo top inclined column away from the silo top frame. One end of a structural column is connected to the outer side wall of each silo top main beam. The other end of each structural column is connected to a variable diameter mechanism on the lower side wall of the silo top main beam. A silo top cover is connected to the top of the silo top frame. Silo top inclined walls are connected to the outer side walls of the several silo top inclined columns. Silo side walls are connected to the outer side walls of the several structural columns.

[0007] The invention is further characterized by: The variable diameter mechanism includes a central column, which is positioned on the axis of the side wall of the storage bin. Both ends of the central column are fitted with force transmission seats. At the opposing edges of the two force transmission seats, and at equal intervals along their circumference, are several T-shaped locking blocks. The bottom of each T-shaped locking block is connected to the force transmission seat. A telescopic frame is fitted onto the vertical rod of each T-shaped locking block. One end of each telescopic frame is connected to a rack. The tooth flank of each rack is perpendicular to the force transmission seat. Each rack meshes with a third gear. A third gear is fitted at the axis of each third gear. The two-core shafts have one end fixedly connected to the force transmission seat. Each third gear meshes with a second gear. A first core shaft is sleeved at the center of each second gear. One end of each first core shaft is fixedly connected to the force transmission seat. Each second gear meshes with the same first gear. The first gear is sleeved on the core column. The number of T-shaped blocks on each force transmission seat is equal to the number of structural columns and corresponds one-to-one. The other end of each telescopic frame is connected to the side wall of its corresponding structural column. Rotary ears are provided at both ends of the core column.

[0008] Each telescopic frame includes a main body with a sliding groove that fits onto the vertical bar of the T-shaped locking block. The main body is positioned below the horizontal bar of the T-shaped locking block.

[0009] Each force transmission seat is connected to the pressure ring through several connecting blocks. The pressure ring contacts the side of several racks away from the force transmission seat, and the center of the pressure ring is located on the axis of the central column.

[0010] Each main beam of the silo roof is connected to a secondary beam on its inner side wall. The end of each secondary beam away from the main beam is connected to a locking frame. The locking frame is fitted onto the top of the silo core column and is located above the first gear.

[0011] The locking frame includes a locking frame collar, which is fitted onto the top of the central column of the warehouse. Several U-shaped locking frame sleeves are connected to the side wall of the locking frame collar along its circumference. The number of U-shaped locking frame sleeves is equal to the number of secondary beams on the warehouse roof and corresponds one-to-one. The open end of each U-shaped locking frame sleeve is located on both sides of the corresponding secondary beam on the warehouse roof. Each U-shaped locking frame sleeve and its corresponding secondary beam on the warehouse roof are connected by a fourth bolt.

[0012] The silo roof slope wall consists of several sector-shaped corrugated plates. Adjacent sector-shaped corrugated plates are connected by silo roof mounting plates. The number of silo roof mounting plates is equal to the number of silo roof slope columns and they correspond one-to-one. The silo roof mounting plates and silo roof slope columns are connected by bolts.

[0013] The side wall of the warehouse consists of several corrugated plates. Adjacent corrugated plates are connected by mounting plates. The number of mounting plates is equal to the number of structural columns and corresponds one-to-one. The mounting plates are connected to the structural columns by bolts.

[0014] Several main beams of the silo roof are equipped with baffles at their top. The upper surface of the baffles contacts the bottom of the silo roof sloping wall, and the lower surface of the baffles contacts the top of the silo side wall.

[0015] Another technical solution adopted in this invention is a method for adjusting the diameter of a silo. The method allows for convenient diameter adjustment of the silo. The specific process is as follows: When the diameter needs to be adjusted, the rotating lug is rotated, which drives the silo center column to rotate. The silo center column drives the first gear to rotate, which in turn drives the second gear and the third gear to rotate. This causes the rack to move in a straight line, which changes the distance between the structural column and the main beam of the silo top. This causes the inclined wall of the silo top and the side wall of the silo to shrink or expand in diameter. After the target diameter is reached, the secondary beam of the silo top and the U-shaped locking frame sleeve are connected and fixed with the fourth bolt, thereby limiting the diameter of the adjusted silo and completing the diameter adjustment.

[0016] The beneficial effects of this invention are: (1) The diameter of the silo of the present invention can be conveniently adjusted. By setting a variable diameter mechanism, the diameter of the silo can be flexibly adjusted as needed. The adjustment method is simple and easy to operate. (2) The diameter of the silo can be easily adjusted. By setting a locking frame, the adjusted diameter can be fixed to prevent the diameter from changing and improve the structural stability.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 The diameter of the silo in this invention can be easily adjusted, and the structure is as follows: Figure 1 and Figure 2As shown, the structure includes a circular silo roof frame 1. Several inclined columns 2 are connected to the side walls of the silo roof frame 1 along its circumference. These inclined columns 2 are spaced evenly to improve structural stability. Each inclined column 2 has a slidably connected main beam 3 at its end away from the silo roof frame 1, allowing the main beam 3 to slide relative to the inclined column 2. Each main beam 3 is arc-shaped, and the main beams 3 form a circle. The outer diameter of the silo roof frame 1 is smaller than the outer diameter of the main beams 3. Each main beam 3 has an outer wall connected to one end of a structural column 7. The number of main beams 3 is equal to the number of structural columns 7. The structural columns 7 are vertically positioned, while the main beams 3 are horizontally positioned. Each structural column 7 is located on the lower side wall of the main beam 3 and on the other side of each structural column 7. One end is connected to the variable diameter mechanism 8. The top of the silo top frame 1 is connected to the silo top cover plate 9. The diameter of the silo top cover plate 9 is larger than the outer diameter of the silo top frame 1. The outer walls of several silo top inclined columns 2 are connected to silo top inclined walls 10. The silo top inclined walls 10 are frustum-shaped. The top of the silo top inclined walls 10 is in contact with the bottom of the silo top cover plate 9. The outer walls of several structural columns 7 are connected to silo side walls 12. The silo side walls 12 are cylindrical. The top of several silo top main beams 3 are supported by baffles 11. The baffles 11 are annular. The inner diameter is not larger than the inner diameter of the circle formed after several silo top main beams 3 are in complete contact. The outer diameter is not smaller than the outer diameter of the circle formed after several silo top main beams 3 are in complete contact. The upper surface of the baffles 11 is in contact with the bottom of the silo top inclined walls 10. The lower surface of the baffles 11 is in contact with the top of the silo side walls 12.

[0021] Example 2 The diameter of the silo in this invention can be easily adjusted, and the structure is as follows: Figure 1 and Figure 2As shown, the structure includes a circular silo roof frame 1. Several inclined columns 2 are connected to the side walls of the silo roof frame 1 along its circumference. These inclined columns 2 are evenly spaced. Each inclined column 2 has a slidably connected main beam 3 at its end furthest from the silo roof frame 1, allowing it to slide relative to the inclined columns 2. Each main beam 3 is arc-shaped, and the main beams 3 form a circle. The outer diameter of the silo roof frame 1 is smaller than the outer diameter of the main beams 3. Each main beam 3 has one end connected to a structural column 7 on its outer side wall. The number of main beams 3 is equal to the number of structural columns 7. The structural columns 7 are vertically positioned, while the main beams 3 are horizontally positioned. Each structural column 7 is located on the lower side wall of the main beam 3, and its other end is connected to a variable... The diameter mechanism 8 is connected, and the top of the silo top frame 1 is connected to the top of the silo top cover plate 9. The diameter of the silo top cover plate 9 is larger than the outer diameter of the silo top frame 1. The outer walls of several silo top inclined columns 2 are connected to silo top inclined walls 10. The silo top inclined walls 10 are truncated cone-shaped. The top of the silo top inclined walls 10 contacts the bottom of the silo top cover plate 9. The outer walls of several structural columns 7 are connected to silo side walls 12. The silo side walls 12 are cylindrical. The top of several silo top main beams 3 are supported by baffles 11. The baffles 11 are annular. The inner diameter is not larger than the inner diameter of the circle formed after several silo top main beams 3 are in complete contact. The outer diameter is not smaller than the outer diameter of the circle formed after several silo top main beams 3 are in complete contact. The upper surface of the baffles 11 contacts the bottom of the silo top inclined walls 10. The lower surface of the baffles 11 contacts the top of the silo side walls 12.

[0022] like Figure 3 As shown, the side wall of the silo top frame 1 is connected to the top of the silo top inclined column 2 by an L-shaped first connecting plate 13 and a first bolt 14. Specifically, one side wall of the L-shaped first connecting plate 13 is connected to the silo top frame 1 by the first bolt 14, and the other side wall of the L-shaped first connecting plate 13 is connected to the side wall of the silo top inclined column 2 by the first bolt 14.

[0023] like Figure 4 As shown, two second connecting plates 16 are symmetrically arranged on the inner side wall of each main beam 3 of the silo top. Each second connecting plate 16 is provided with a strip groove 15. The end of the inclined column 2 of the silo top away from the silo top frame 1 is located between the two second connecting plates 16. It also includes a second bolt 17. The second bolt 17 passes through one of the strip grooves 15, the inclined column 2 of the silo top, and the other strip groove 15 in sequence. When the diameter is changed, the main beam 3 of the silo top moves to reduce or expand its diameter under the drive of the diameter changing mechanism. The strip groove 15 slides relative to the second bolt 17 to realize the diameter change.

[0024] The inner wall of each main beam 3 of the warehouse roof is connected to the structural column 7 through an L-shaped third connecting plate 18 and a third bolt 19. Specifically, one side wall of the L-shaped third connecting plate 18 is connected to the inner wall of the main beam 3 of the warehouse roof through a third bolt 19, and the other side of the L-shaped third connecting plate 18 is connected to the side wall of the structural column 7 through a third bolt 19.

[0025] Example 3 Based on Example 2, such as Figure 5 As shown, the variable diameter mechanism 8 includes a core column 6, which is located on the axis of the side wall 12 of the storage compartment. Both ends of the core column 6 are fitted with force transmission seats 91. Several T-shaped locking blocks 82 are evenly spaced along the circumferential direction at the opposing edges of the two force transmission seats 91. The bottom of each T-shaped locking block 82 is connected to the force transmission seat 91. A telescopic frame 81 is fitted onto the vertical rod of each T-shaped locking block 82. The T-shaped locking blocks 82 are used to limit the axial movement of the telescopic frame 81. Each telescopic frame 81 has a rack 87 connected to one end. The tooth flanks of each rack 87 are perpendicular to the force transmission seat 91. Each rack 87 meshes with a third gear 86. A second spindle 89 is sleeved at the shaft of each third gear 86. One end of each second spindle 89 is fixed to the force transmission seat 91. Each third gear 86 meshes with a second gear 85. A first spindle 88 is sleeved at the shaft of each second gear 85. One end of each first spindle 88 is connected to the force transmission seat. 91 is fixedly connected. Each second gear 85 meshes with the same first gear 84. The first gear 84 is sleeved on the central column 6, causing the central column 6 to rotate. The central column 6 drives the first gear 84 to rotate, the first gear 84 drives the second gear 85 to rotate, the second gear 85 drives the third gear 86 to rotate, and the third gear 86 drives the rack 87 to move linearly. The number of T-shaped blocks 82 on each force transmission seat 91 is equal to the number of structural columns 7 and corresponds one-to-one. The other end of each telescopic frame 81 is connected to the side wall of its corresponding structural column 7. Each force transmission seat 91 is connected to a pressure ring 83 through several connecting blocks 93. The pressure ring 83 contacts the side of several racks 87 away from the force transmission seat 91. The center of the pressure ring 83 is located on the axis of the central column 6, that is, the rack 87 is located between the force transmission seat 91 and the pressure ring 83. The pressure ring 83 is used to limit the position of the rack 87 to prevent it from disengaging from the third gear 86 and to ensure that the rack 87 and the third gear 86 are in contact for force transmission.

[0026] Example 4 Based on Example 3, such as Figure 6As shown, both ends of the silo core column 6 are provided with rotating ears 20. The rotating ears 20 are used to rotate the silo core column 6. The specific operation process is as follows: rotating the rotating ears 20 causes the silo core column 6 to rotate, which in turn causes the first gear 84 to rotate, which in turn causes the second gear 85 to rotate, which in turn causes the third gear 86 to rotate, which in turn causes the rack 87 to move linearly (radially along the force transmission seat 91). This causes the distance between the structural column 7 and the silo top main beam 3 to change, which causes the silo top inclined wall 10 and the silo side wall 12 to reduce or expand their diameter.

[0027] Example 5 Based on embodiment 4, each telescopic frame 81 includes a body 92, on which a sliding groove 90 is provided. The sliding groove 90 is fitted onto the vertical rod of the T-shaped locking block 82, and the body 92 is located below the horizontal rod of the T-shaped locking block 82, thereby limiting the body 92 to move only along its axial direction.

[0028] Example 6 Based on embodiment 5, each main beam 3 of the warehouse top is connected to a secondary beam 4 of the warehouse top. The end of each secondary beam 4 away from the main beam 3 of the warehouse top is connected to a locking frame 5. The locking frame 5 is sleeved on the top of the warehouse core column 6 and is located above the first gear 84. The locking frame 5 is used to fix the diameter after the diameter adjustment is completed.

[0029] like Figure 7 As shown, the locking frame 5 includes a locking frame collar 52, which is sleeved on the top of the central column 6. Several U-shaped locking frame sleeves 51 are connected to the side wall of the locking frame collar 52 along its circumference. The U-shaped locking frame sleeves 51 are evenly spaced. The closed end of each U-shaped locking frame sleeve 51 is connected to the side wall of the locking frame collar 52. The number of U-shaped locking frame sleeves 51 is equal to the number of secondary beams 4 on the warehouse top and they correspond one-to-one. The open end of each U-shaped locking frame sleeve 51 is located on both sides of the corresponding secondary beam 4 on the warehouse top. Each U-shaped locking frame sleeve 51 and its corresponding secondary beam 4 on the warehouse top are connected by a fourth bolt 53.

[0030] Furthermore, each U-shaped locking sleeve 51 and the side wall of the secondary beam 4 of the warehouse top are provided with several holes, which are used to fix the diameter after the diameter adjustment is completed by passing the fourth bolt 53 through the holes on the U-shaped locking sleeve 51 and the secondary beam 4 of the warehouse top in one go, so as to prevent the diameter from changing again and to fix the diameter.

[0031] Example 7 Based on embodiment 6, the silo roof inclined wall 10 includes a number of fan-shaped corrugated plates 121. Two adjacent fan-shaped corrugated plates 121 are connected by silo roof mounting plates 122. The number of silo roof mounting plates 122 is equal to the number of silo roof inclined columns 2 and corresponds one-to-one. The silo roof mounting plates 122 and the silo roof inclined columns 2 are connected by bolts.

[0032] The side wall 12 of the warehouse includes several corrugated plates 141. Two adjacent corrugated plates 141 are connected by mounting plates 142. The number of mounting plates 142 is equal to the number of structural columns 7 and corresponds one-to-one. The mounting plates 142 are connected to the structural columns 7 by bolts.

[0033] Corrugated plates are used to meet the sidewall requirements when adjusting the diameter.

[0034] Example 8 The silo diameter adjustment method of the present invention allows for convenient adjustment of the silo using the aforementioned diameter. The specific process is as follows: When the diameter needs to be adjusted, the rotating lug 20 is rotated, which drives the silo center column 6 to rotate. The silo center column 6 drives the first gear 84 to rotate, the first gear 84 drives the second gear 85 to rotate, the second gear 85 drives the third gear 86 to rotate, and the third gear 86 drives the rack 87 to move linearly (radially along the force transmission seat 91). This causes a change in the distance between the structural column 7 and the silo top main beam 3, which in turn causes the silo top inclined wall 10 and the silo side wall 12 to shrink or expand in diameter. After the target diameter is reached, the silo top secondary beam 4 and the U-shaped locking frame sleeve 51 are connected and fixed with the fourth bolt 53, thereby limiting the adjusted silo diameter and completing the diameter adjustment.

[0035] Specifically: when the rack 87 moves toward the central column 6, it is a reduction in diameter; when the rack 87 moves away from the central column 6, it is an expansion in diameter.
