Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically a grain storage silo that is easy to assemble and erect on-site. Background Technology

[0002] Grain silos are used for storing grain and are commonly divided into two types: those built with cement concrete and those with welded steel frames. Cement concrete silos are structurally stable, have high compressive strength, and are resistant to wind and rain. However, their construction is time-consuming, labor-intensive, and costly. Once completed, their capacity is fixed and they are difficult to move. Welded steel frame silos, on the other hand, offer greater flexibility. They are composed of steel frames and plates, assembled using bolts and / or welding, making them easy to disassemble and transport. However, whether welded or bolted, on-site assembly is cumbersome, labor-intensive, and requires multiple people, especially welding, which demands high technical skills and is inconvenient for on-site operations. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a grain storage silo that is convenient for on-site assembly and erection.

[0004] The technical solution of this utility model is as follows:

[0005] A grain storage silo that is easy to assemble and erect on site includes a silo frame, a silo roof, and several silo walls;

[0006] The warehouse rack consists of several vertical supports arranged in a horizontal ring. The tops of adjacent supports are connected by crossbeams. The warehouse roof is installed on top of the warehouse rack, and the warehouse walls are sealed between adjacent supports.

[0007] The warehouse wall includes an upper wall panel, a lower wall panel, and at least one intermediate wall panel. Several wall panels are arranged vertically and connected in sequence, and both sides are sealed to the support columns. The upper part of the intermediate wall panel and the lower wall panel is bent with an upper folding plate, and the lower part of the intermediate wall panel and the upper wall panel is bent with a first lower folding plate and a second lower folding plate. The upper folding plate, the first lower folding plate, and the second lower folding plate are located on the same side of the wall panel surface.

[0008] The upper folding plate has a first upper sloping section, an upper straight section and a second upper sloping section that are bent upwards from the upper edge of the wall panel. The bending direction of the second upper sloping section is opposite to that of the first upper sloping section. A retaining strip protrudes upwards from the upper side of the first upper sloping section.

[0009] The first lower folding plate bends downwards from the lower edge of the wall panel, forming a first lower sloping section and a first lower straight section. The second lower folding plate bends downwards from one side of the wall panel, forming a second lower sloping section and a second lower straight section. The lower end of the second lower straight section is higher than the upper end of the first lower straight section.

[0010] When adjacent wall panels are connected, the upper straight section is sandwiched between two lower straight sections, the second upper inclined section abuts against the second lower inclined section, and the lower end of the first lower straight section is sandwiched between the upper straight section and the retaining strip.

[0011] Preferably, the first downward slope, the second downward slope, and the second upward slope are parallel to each other.

[0012] Preferably, the inclination angles of the first upper inclined section, the second upper inclined section, the first lower inclined section, and the second lower inclined section are 40 to 50 degrees to improve the structural strength of the folded plate and thus provide more stable support.

[0013] Preferably, the upper folding plate, the first lower folding plate, and the second lower folding plate are located on the side of the wall panel facing the inner cavity of the grain storage silo.

[0014] Preferably, the lower edges of the middle wall panel and the upper wall panel extend downwards with rain shields to prevent rainwater from entering between the folding plate and the two lower folding plates, thereby preventing corrosion and water from entering the grain storage silo.

[0015] Preferably, several wall panels are vertically aligned, and the lower end of the rain shield abuts against the upper edge of the adjacent wall panel below, so as to completely cover the upper and lower folding panels.

[0016] Ideally, there should be a gap between the strip and the rain shield to prevent it from sticking to the rain shield and causing capillary water absorption, thus improving the rainproof effect.

[0017] Preferably, the wall panel has connecting plates on both sides, and the connecting plates have mounting holes. The connecting plates are fixed to the support column by screws passing through the mounting holes. When adjacent wall panels are connected, the connecting plates fit against the side of the support column, and the upper and lower connecting plates on the same side of the adjacent wall panels are connected. The wall panels can be installed and disassembled through the connecting plates.

[0018] Preferably, a waterproof strip is provided between the connecting plate and the support column to improve the waterproof performance between the connecting plate and the support column and prevent water seepage between them.

[0019] Preferably, the silo roof includes a silo roof frame installed on several crossbeams and a cover plate covering the silo roof frame, and the silo roof is provided with ventilation openings.

[0020] This utility model provides a grain storage silo that is easy to assemble and erect on-site. First, the silo frame, silo roof, and several silo walls are all detachably connected, facilitating transportation and relocation. Second, through the setting and interlocking of the upper folding plate and two lower folding plates, the pre-installed and fixed lower wall panels can support the newly placed upper wall panels without the need for support, thus freeing up manpower and facilitating the assembly of the wall panels by workers, reducing the difficulty of on-site assembly. Finally, the wall panels, supports, beams, and silo roof can all be pre-welded or processed, eliminating the need for welding during assembly and reducing welding difficulty.

[0027] like Figures 1 to 3 As shown, this utility model embodiment provides a grain storage silo that is easy to assemble and erect on site, including a silo frame 1, a silo top 2 and several silo walls 3;

[0028] The warehouse frame 1 includes several vertical support columns 11, which are arranged in a horizontal ring. A crossbeam 12 is connected between the tops of adjacent support columns 11. The warehouse roof 2 is installed on the top of the warehouse frame 1, and the warehouse wall 3 is sealed between adjacent support columns 11.

[0029] The warehouse wall 3 includes an upper wall panel 31, a lower wall panel 32, and at least one intermediate wall panel 33. Several wall panels are arranged vertically and connected in sequence, and both sides are sealed to the support column 11. The upper part of the intermediate wall panel 33 and the lower wall panel 32 is bent with an upper folding plate 34, and the lower part of the intermediate wall panel 33 and the upper wall panel 31 is bent with a first lower folding plate 35 and a second lower folding plate 36. The upper folding plate 34, the first lower folding plate 35, and the second lower folding plate 36 are located on the same side of the wall panel surface.

[0030] The upper folding plate 34 is bent upwards from the upper edge of the wall panel in sequence to form a first upper inclined section 341, an upper straight section 342, and a second upper inclined section 343. The bending direction of the second upper inclined section 343 is opposite to that of the first upper inclined section 341. A retaining strip 344 protrudes upwards from the upper side of the first upper inclined section 341.

[0031] The first lower folding plate 35 is bent downwards from the lower edge of the wall panel to form a first lower inclined section 351 and a first lower straight section 352. The second lower folding plate 36 is bent downwards from one side of the wall panel to form a second lower inclined section 361 and a second lower straight section 362. The lower end of the second lower straight section 362 is higher than the upper end of the first lower straight section 352.

[0032] When adjacent wall panels are connected, the upper straight section 342 is sandwiched between two lower straight sections, the second upper inclined section 343 abuts against the second lower inclined section 361, and the lower end of the first lower straight section 352 is sandwiched between the upper straight section 342 and the retaining strip 344.

[0033] The specific explanation is as follows:

[0034] The number of support pillars 11 is not limited and can be set according to actual needs. In this embodiment, for ease of description, the number of support pillars 11 is set to four, arranged in a square array. However, in reality, since grain storage silos are usually large in volume, multiple support pillars 11 will be set between adjacent support pillars 11 in the square array to reduce the bearing pressure on the crossbeam 12 and shorten the lateral extension length of the wall panel, so that the wall panel will not easily deform due to excessive length and improve the bearing capacity of the wall panel.

[0035] The crossbeam 12 and the support column 11 are connected by screws or bolts to make the silo frame 1 detachable, which facilitates the transportation and transfer of the grain storage silo.

[0036] The upper part of the upper wall panel 31 can be sealed to the crossbeam 12 by screws.

[0037] Furthermore, the grain storage silo provided in this embodiment allows the lower end of the support column 11 to be directly installed on a pre-made foundation or base plate, with the lower edge of the lower wall panel 32 sealingly abutting against the foundation or base plate. The foundation can be, for example, a cement platform, and the base plate can be, for example, made of metal plate.

[0038] In another embodiment, an installation beam may be connected between the lower ends of adjacent support columns 11, and the installation beam is sealed to the foundation or base plate. The installation beam helps to improve the structural stability of the silo frame 1, and at the same time, the lower part of the lower wall panel 32 can be sealed to the installation beam, improving the sealing performance of the grain storage silo cavity.

[0039] Furthermore, a suspended frame can be installed below the support column 11. When the suspended frame supports the silo below the support column 11, the silo frame is lifted off the ground and supported in the air. A bucket-shaped silo bottom is installed on the installation beam, and a grain discharge valve is installed at the bottom of the silo. The bottom of the silo is sealed to facilitate grain discharge.

[0040] The core design feature of this application does not lie in the bottom structure design of the grain storage silo. The above-mentioned placement and connection methods of grain storage silos can all achieve the function of storing grain and can be used normally. Moreover, the foundation, base plate, mounting beam and silo bottom mentioned above are all conventional designs in this field. Therefore, this application does not limit or describe them in detail.

[0041] Please refer to Figure 2 and Figure 3 As shown, the wall panel can preferably be a corrugated plate so that the wall panel has better pressure bearing capacity and deformation resistance.

[0042] In addition, the design of the upper folding plate 34, the first lower folding plate 35 and the second lower folding plate 36 not only enables the lower wall panel to support the upper wall panel, but also further improves the deformation resistance of the wall panel at the connection through the bending structure of the upper folding plate 34 and the two lower folding plates.

[0043] In this embodiment, the upper folding plate 34, the first lower folding plate 35, and the second lower folding plate 36 are all located on the side of the wall panel facing the inner cavity of the grain storage silo.

[0044] The second lower folding plate 36 is located above the first lower folding plate 35. The lower end of the second lower straight section 362 is higher than the upper end of the first lower straight section 352, and there is a gap between it and the first lower folding plate 35. This gap is sufficient for the second upper inclined section 343 to be inserted.

[0045] The first downward inclined section 351, the second downward inclined section 361, and the second upward inclined section 343 are preferably parallel to each other, and the inclination angle of the first upward inclined section 341, the second upward inclined section 343, the first downward inclined section 351, and the second downward inclined section 361 is preferably 40 to 50 degrees, so as to improve the structural strength of the folded plate, improve its bending resistance, and thus provide a more stable support force.

[0046] The lengths of the first lower straight segment 352 and the second lower straight segment 362 are less than the length of the upper straight segment 342.

[0047] During installation, the current wall panel is moved so that the second upper inclined section 343 of the lower wall panel is inserted into the gap between the two lower folds of the current wall panel. In this embodiment, when the second upper inclined section 343 is inserted, it is in contact with the first lower inclined section 351 and slides at an angle until the first lower straight section 352 is in contact with the upper straight section 342. At this time, the end of the second upper inclined section 343 preferably abuts against the surface of the wall panel to provide a fulcrum and support for the current wall panel.

[0048] Then, the current wall panel is moved downwards, causing the second lower straight section 362 to begin sliding against the other side of the upper straight section 342. Simultaneously, the end of the first lower straight section 352 is inserted between the upper straight section 342 and the retaining strip 344, until the second upper inclined section 343 abuts against the second lower inclined section 361. At this point, the two lower straight sections abut against and clamp against the two sides of the upper straight section 342, and the upper straight section 342 and the retaining strip 344 clamp the first lower straight section 352. The lower wall panel provides support to the current wall panel through the clamping of the above two parts, resulting in higher stability.

[0049] In addition, when the two wall panels are connected together, the lower end of the first lower straight section 352 preferably abuts against the first upper straight section 342. Under the weight of the current wall panel, the first lower straight section 352 will have a downward sliding tendency, making it fit more tightly against the retaining strip 344. Similarly, the second upper inclined section 343 abuts against the second lower inclined section 361. Under the weight of the current wall panel, the second lower inclined section 361 will have a downward sliding tendency, making the end of the second upper inclined section 343 fit more tightly against the current wall panel, thereby improving the support stability of the current wall panel.

[0050] In addition, in some embodiments, several pairs of corresponding connecting holes may be opened on both the second lower straight section 362 and the upper straight section 342, and the two adjacent wall panels may be further tightly connected by screws passing through the connecting holes on the second lower straight section 362 and the upper straight section 342.

[0051] In this embodiment, the lower edges of the middle wall panel 33 and the upper wall panel 31 extend downwards with rain shields 37 to prevent rainwater from entering between the upper folding plate 34 and the two lower folding plates, thereby preventing the folding plates from rusting and seeping.

[0052] In addition, several wall panels are vertically aligned, and the lower end of the rain shield 37 abuts against the upper edge of the adjacent wall panel below, so as to completely cover the upper folding plate 34 and the lower folding plate, thereby improving the flatness and aesthetics of the warehouse wall 3.

[0053] In addition, there is a better distance between the strip 344 and the rain shield 37 to avoid capillary water absorption caused by contact with the rain shield 37, thereby improving the rainproof effect.

[0054] In this embodiment, the lateral extension length of the upper folding plate 34, the two lower folding plates, the clip 344, and the rain shield 37 is the same as the lateral extension length of the wall panel.

[0055] The wall panel is provided with connecting plates 38 on both sides. The connecting plates 38 are provided with several mounting holes 381. The connecting plates 38 are installed with the support column 11 by screws passing through the mounting holes 381. When adjacent wall panels are connected, the connecting plates 38 are in contact with the side of the support column 11, and the upper and lower connecting plates 38 on the same side of the adjacent wall panels are connected. The wall panels are installed and disassembled through the connecting plates 38.

[0056] A waterproof strip is preferably provided between the connecting plate 38 and the support column 11, extending vertically to improve the waterproof and sealing performance between the connecting plate 38 and the support column 11, and to prevent water seepage between them. The sealing strip is preferably located closer to the inner wall of the grain storage silo than the mounting hole 381.

[0057] In addition, the mating positions of the two corresponding connecting plates 38 can be pre-applied with sealant, such as silicone sealant, during installation to further improve the water-proof performance of the silo wall 3.

[0058] Please see again. Figure 1 In this application, the silo roof 2 is not a core design feature, and its structure is not limited. It can be any existing structure capable of providing a roof in the field. For example, in this embodiment, the silo roof 2 includes a silo roof 2 frame (not shown in the figure) mounted on several crossbeams 12 and a cover plate covering the silo roof 2 frame. The frame is umbrella-shaped, with its lower end detachably connected to the crossbeams 12. The cover plate can be made of metal and is sealed and laid on the frame, connected to it. The silo roof 2 also has ventilation openings that communicate with the inner cavity of the grain storage silo, and an entrance / exit for staff to enter and exit the grain storage silo for inspection, as well as for loading and unloading grain.

[0059] This utility model provides a grain storage silo that is easy to assemble and erect on-site. First, the silo frame 1, silo roof 2, and several silo walls 3 are all detachably connected, facilitating transportation and relocation. Second, through the setting and interlocking of the upper folding plate 34 and two lower folding plates, the wall panels that have just been placed above can be supported by the wall panels that have been installed and fixed below, eliminating the need for support and thus freeing up manpower, making it easier for workers to assemble the wall panels and reducing the difficulty of on-site assembly. Finally, the upper folding plate 34, the two lower folding plates, the clamping strip 344, and the rainproof plate 37 can all be pre-welded or processed, reducing the difficulty of welding.
