Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and more specifically, it relates to a spiral steel silo for grain storage. Background Technology

[0002] In the field of rural grain storage, the flexibility and convenience of household grain security reserve systems are receiving increasing attention.

[0003] Currently, household grain storage spiral steel silos on the market adopt a detachable design, which can flexibly adjust the number of silo sections according to seasonal harvest and storage needs. This modular design concept meets the actual needs of farmers with different grain storage capacities.

[0004] However, most existing connection mechanisms use traditional bolt connections or complex snap-fit ​​systems. When farmers need to frequently adjust storage capacity according to harvest conditions, operators often have to spend a significant amount of time disassembling and installing these connections, sometimes even requiring specialized tools for tedious disassembly and assembly. Especially during the busy harvest season, this inefficient method of adjusting storage silos not only increases labor intensity and prolongs adjustment time, but also fails to meet the urgent needs of modern agriculture for rapidly adaptable grain storage equipment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a spiral steel plate silo for grain storage to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a spiral steel plate silo for grain storage, comprising a base, a lower silo fixedly mounted on the base, a support plate fixedly mounted on the outer wall of the lower silo, an upper silo above the lower silo, a fixing plate fixedly mounted on the outer wall of the upper silo, a middle silo between the upper and lower silos, multiple sets of fixing mechanisms mounted on the support plate, each fixing mechanism comprising a rod and a fixing sleeve, the rod being fixed to the top surface of the support plate and inserted into the fixing plate, the fixing sleeve being inserted into the top of the rod and abutting against the top surface of the fixing plate, a sliding groove being formed on the outer wall of the rod, multiple sets of sliding grooves being slidably connected to locking blocks, compression springs being connected between the multiple sets of locking blocks and the sliding grooves, a retaining ring being fixedly mounted on the inner side of the fixing sleeve, the outer sides of the multiple sets of locking blocks and the inner sides of the retaining rings being set as inclined surfaces, an unlocking sleeve being slidably mounted on the inner side of the fixing sleeve, a push block being fixedly mounted on the inner side of the unlocking sleeve, and a silo top being fixedly mounted on the top of the upper silo.

[0009] The present invention is further configured such that a slider is fixedly provided on the outer wall of the unlocking sleeve, and a groove is provided on the outer wall of the fixed sleeve. Multiple sets of sliders and grooves are provided and slidably connected. This design of slider and groove ensures that the unlocking sleeve slides smoothly along the predetermined track during movement, effectively preventing jamming or deviation during unlocking operation, and improving the accuracy and smoothness of unlocking action.

[0010] The present invention is further configured such that an annular groove is provided on the outer wall of the fixed sleeve, and a rotating sleeve is rotatably provided on the outer wall of the fixed sleeve. A limiting plate is fixedly provided at the top of the rotating sleeve. The limiting plate is provided with multiple sets that slide in the annular groove. The combination design of the annular groove and the limiting plate forms a rotation limiting mechanism, which enables the limiting plate to move smoothly along the annular trajectory, realizes all-round control of the fixed mechanism, and ensures the stability and reliability of the rotation process of the rotating sleeve.

[0011] The present invention is further configured such that each of the multiple sets of sliders has a limiting groove on its outer wall, and the multiple sets of limiting plates abut against the multiple sets of limiting grooves respectively. The precise cooperation between the limiting plates and the limiting grooves forms a reliable locking system, which can effectively prevent the slider from moving accidentally in the fixed state. At the same time, during the unlocking operation, the limiting is released synchronously by rotating the rotating sleeve, which greatly improves the operation safety and convenience of the device.

[0012] The present invention is further configured such that a positioning block is slidably provided on the outer wall of the rotating sleeve, and multiple sets of positioning blocks are provided, each with a return spring connected to its top end. The bottom ends of the multiple sets of return springs are fixedly connected to the outer wall of the rotating sleeve. The outer wall of the fixed sleeve is provided with a positioning groove, and multiple sets of positioning grooves are provided, each abutting against multiple sets of positioning blocks. The meshing structure of the positioning block and the positioning groove, combined with the elastic support of the return spring, forms a precise angle positioning system, ensuring that the rotating sleeve can accurately stop at the preset position, effectively avoiding the problem of accidental rotation and loosening of the silo due to vibration or external force during use.

[0013] The present invention is further configured such that a threaded sleeve is threadedly connected to the outer wall of the fixed sleeve, and a thrust bearing is connected to the top of the threaded sleeve. A limiting sleeve is slidably provided on the outer wall of the fixed sleeve, and the limiting sleeve is rotatably connected to the thrust bearing. The combination design of the threaded sleeve and the thrust bearing realizes the conversion of rotational force and axial force. The axial movement of the limiting sleeve can be precisely controlled by a simple rotation operation, which greatly reduces the operation force required, while improving the adjustment accuracy and operation convenience of the locking mechanism.

[0014] The present invention is further configured such that a movable groove is provided on the inner side of the insertion rod, and a compression spring is connected in the movable groove. A stop plate is fixed on the top of the compression spring. The compression spring and the stop plate in the movable groove are designed to form a buffer and shock absorption mechanism, which can effectively absorb vibration and impact during the installation and use of the silo, reduce stress concentration at the connection, protect the fixed structure from damage, and extend the service life of the entire device.

[0015] The present invention is further configured such that the fixing plate has multiple sets of insertion holes, each with rounded corners on its outer side; the bottom surface of the upper silo and the top surface of the lower silo both have connecting grooves; and the two ends of the middle silo abut against the connecting grooves respectively. The rounded corner design of the insertion holes reduces the frictional resistance when inserting the insertion rod, enabling the fixing plate to be positioned quickly and accurately. The precise fit between the connecting grooves and the middle silo ensures the tightness of the silo connection and the overall stability, effectively avoiding grain leakage and unstable storage space, and improving the practicality and safety reliability of the steel silo.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a spiral steel plate silo for grain storage, which has the following beneficial effects:

[0018] 1. This spiral steel silo for grain storage cleverly solves the problem of cumbersome operation during the adjustment of traditional spiral steel silos through its innovative fixing mechanism design. Farmers only need to align the insertion rod with the insertion hole on the fixing plate and insert it. The rounded corner design on the outside of the insertion hole will automatically push the locking block into the sliding groove. After the fixing sleeve and the insertion rod are fully inserted, the compression spring will automatically reset and push the locking block to abut against the locking ring. The entire installation process is simple and intuitive and requires no professional tools, which greatly improves the installation efficiency and convenience of the silo. It is especially suitable for busy farming conditions during the harvest season in rural areas, effectively shortening the adjustment time of the silo and reducing labor intensity, perfectly meeting the urgent needs of modern agriculture for rapid adaptability of grain storage equipment.

[0019] 2. The unlocking and disassembly mechanism of this device is also scientifically and efficiently designed. By rotating the threaded sleeve counterclockwise, the thrust bearing pulls the limiting sleeve to release the contact with the positioning block. The return spring drives the positioning block to disengage from the positioning groove. Then, the rotating sleeve is rotated to make the limiting plate disengage from the limiting groove. Finally, the push block is pushed to drive the unlocking sleeve to abut against the locking block, realizing the quick unlocking function. This design not only greatly reduces the time and complexity of disassembling the silo, but also effectively avoids the problems of loose connection and poor sealing that are easy to occur in traditional fixed structures. Even in seasonal use environments, it can still maintain stable and reliable operation performance, making silo adjustment easy and convenient, and greatly improving the practicality and adaptability of steel silos.

[0020] 3. This spiral steel silo for grain storage also integrates several refined structural optimization designs. The modular combination is achieved through the design of the two ends of the central silo abutting into the connecting grooves. The rounded corner design between the insertion rod and the insertion hole provides a smooth insertion experience. The cooperation between the slider and the unlocking sleeve ensures precise control during the disassembly process. The combination of the rotating sleeve and the limiting plate provides a reliable locking mechanism. These carefully considered structural details together construct a grain storage system that is both easy to operate and highly efficient and reliable. This greatly improves the overall performance and user experience of the steel silo, providing farmers with a more flexible, efficient, and convenient grain storage solution. It effectively increases farmers' acceptance of new grain storage technologies and meets the comprehensive requirements of rural grain storage for convenience, efficiency, and safety.

[0037] The fixing plate 5 has a set of insertion holes 31, and each of the insertion holes 31 has rounded corners on the outside. The bottom surface of the upper chamber 4 and the top surface of the lower chamber 2 are both provided with connecting grooves 32, and the two ends of the middle chamber 6 are respectively abutted in the connecting grooves 32.

[0038] In this embodiment, during use, the two ends of the central cylinder 6 are respectively abutted into the connecting groove 32, and multiple sets of insert rods 7 are inserted into the insertion holes 31. The insertion holes 31 abut against multiple sets of locking blocks 10, causing them to slide into the sliding groove 9 and compressing the compression spring 11. At the same time, the fixing sleeve 8 is inserted into the insert rods 7, and the retaining ring 12 abuts against the outside of the multiple sets of locking blocks 10.

The rotating sleeve 19 is rotated to drive the multiple sets of limiting plates 20 to disengage from the limiting groove 21, releasing the limiting of the multiple sets of sliders 16. The push block 14 is pushed so that the unlocking sleeve 13 abuts against the outer wall of the multiple sets of locking blocks 10, causing the multiple sets of locking blocks 10 to release their contact with the retaining ring 12 and slide into the sliding groove 9. Then the fixing sleeve 8 can be separated from the insertion rod 7, and the fixing plate 5 can be separated from the insertion rod 7, thus completing the unlocking of the upper chamber 4 and the lower chamber 2.

[0040] In summary, during use or operation of the overall equipment: When in use, the two ends of the central chamber 6 are respectively abutted into the connecting groove 32. Simultaneously, multiple sets of insert rods 7 are inserted into the insertion holes 31. The insertion holes 31 abut against multiple sets of locking blocks 10, causing them to slide into the sliding groove 9 and compressing the compression spring 11. At the same time, the fixing sleeve 8 is inserted into the insert rods 7, and the retaining ring 12 abuts against the outside of the multiple sets of locking blocks 10. When the multiple sets of locking blocks 10 are fully inserted into the fixing sleeve 8, the multiple sets of compression springs 11 reset and push the locking blocks 10 back into place. 0 slides out of the sliding groove 9 and makes the bottom surface of multiple sets of locking blocks 10 abut against the locking ring 12, thereby completing the abutment and fixation of the fixing plate 5.

[0041] When it is necessary to unlock the upper chamber 4 and the lower chamber 2, rotate the threaded sleeve 25 counterclockwise to pull the limiting sleeve 27 through the thrust bearing 26 to release it from the contact with the multiple sets of positioning blocks 22. The multiple sets of return springs 23 pull the positioning blocks 22 so that their bottom ends are disengaged from the positioning groove 24, releasing the positioning of the rotating sleeve 19. Rotate the rotating sleeve 19 to drive the multiple sets of limiting plates 20 to disengage from the limiting groove 21, releasing the limiting of the multiple sets of sliders 16.
