Description

Technical Field

[0001] This utility model belongs to the technical field of screw conveyors, specifically relating to a screw conveyor with an anti-jamming structure. Background Technology

[0002] A screw conveyor is a type of conveying machinery that uses rotating helical blades to transport materials without inflexible traction components. It is also known as an auger. After the material enters the fixed trough of the screw conveyor from the feed inlet, the drive device drives the screw shaft to rotate. Due to its own mass, the internal friction between particles, and the external friction with the trough wall, the material cannot rotate with the screw. Instead, it is driven forward along the trough by the axial force of the screw, similar to a nut moving forward along the axis when rotating on a fixed screw. When it reaches the discharge port, the material is discharged.

[0003] However, existing materials are prone to blockage and jamming in the gap between the screw and the trough during the conveying process. This not only affects the conveying efficiency, but may also damage the equipment, increase maintenance costs and downtime, and fail to ensure the stable and efficient operation of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a screw conveyor with an anti-jamming structure to solve the problem mentioned in the background art that existing materials are prone to blockage and jamming in the gap between the screw and the trough during the conveying process. This not only affects the conveying efficiency, but may also cause equipment damage, increase maintenance costs and downtime, and fail to ensure the stable and efficient operation of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw conveyor with an anti-jamming structure, comprising a screw conveyor body;

[0006] A drive motor is installed on the left side of the main body of the screw conveyor, a drive rod is installed inside the drive motor, a protective cover is installed on the right side of the drive motor, a screw rod is installed inside the protective cover, the screw rod is connected to the drive rod flange, and a feed inlet and a discharge outlet are respectively provided on the top two sides of the protective cover.

[0007] There is a sliding sleeve on the outer side of the screw rod, a screw is provided inside the sliding sleeve, and a spiral conveying blade is provided on the outer side of the sliding sleeve.

[0008] Preferably, the inner side of the sliding sleeve is provided with a nesting element in an annular array, and the outer side of the screw is provided with a sliding groove in an annular array.

[0009] Preferably, the nested component is nested with the slide groove, and the sliding sleeve and the screw are slidably connected to the slide groove through the nested component.

[0010] Preferably, limit rings are provided on the left and right sides of the sliding sleeve, and nesting parts are also provided inside the limit rings. Fixing holes are arranged in an array inside the screw, and limit holes are arranged in an annular array outside the limit rings.

[0011] Preferably, a fixing bolt is provided inside the fixing hole and the limiting hole, and the limiting ring and the screw are fixedly connected by the fixing bolt.

[0012] Preferably, mounting rings are provided on the left and right sides of the sliding sleeve, a mounting sleeve is provided on the outer side of the mounting ring, a mounting sleeve is also provided on the outer side of the limiting ring, and a telescopic cloth is provided in the middle of the limiting ring and the mounting ring.

[0013] Preferably, the outer annular array of the mounting ring and the limiting ring has mounting holes, and mounting bolts are provided inside the mounting holes. The two ends of the telescopic cloth are fixed by mounting bolts and mounting sleeves.

[0014] Preferably, the stretch fabric is made of high-density polyester, and dust covers are provided on the outer sides of the transmission rod and the screw rod.

[0015] Compared with the prior art, this utility model provides a screw conveyor with an anti-jamming structure, which has the following beneficial effects:

[0016] 1. Through the configuration of a sliding sleeve, screw, spiral conveyor blades, nesting parts, chute, limiting ring, fixing hole, and fixing bolt, the sliding sleeve and screw are slidably connected via the nesting parts and the chute. When the spiral conveyor encounters local blockage or significant resistance during material conveying, the sliding sleeve can slide relative to the screw. This feature effectively prevents the spiral conveyor blades from being jammed by material, ensuring the continuity of material conveying, greatly improving the equipment's anti-jamming capability, and reducing downtime and equipment damage risks caused by material jamming. The nesting parts inside the limiting ring cooperate with the chute on the screw, and the limiting ring is fixedly connected to the screw via fixing bolts passing through the fixing hole and the limiting hole. This precisely limits the sliding range of the sliding sleeve, ensuring stable sliding of the sliding sleeve during normal operation and preventing it from excessively sliding and detaching from the screw, thereby ensuring the stability of the entire spiral conveyor structure and enabling the equipment to operate reliably for a long time. This modular and robustly connected structural design allows for easy disassembly and installation of various components when the equipment malfunctions or requires maintenance, reducing maintenance costs and difficulty.

[0017] 2. Through the installation of the mounting ring, mounting sleeve, telescopic cloth, mounting holes, and mounting bolts, the telescopic cloth is installed between the limiting ring and the mounting ring. This effectively prevents material from leaking out through the gap between the sliding sleeve and the limiting ring. During the material conveying process of the screw conveyor, this protective measure avoids material scattering, maintains a clean working environment, reduces material loss, and improves the efficiency and economy of material conveying. The mounting holes on the outside of the mounting ring and the limiting ring cooperate with the mounting bolts to firmly fix both ends of the telescopic cloth through the mounting sleeve. This installation method is simple and direct, making it easy for operators to perform during equipment assembly and maintenance. At the same time, the cooperation of the mounting bolts and the mounting sleeve provides reliable fixing force, ensuring that the telescopic cloth will not loosen or fall off during equipment operation, and maintaining a long-term sealing effect on the material.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-5The screw conveyor shown includes a screw conveyor body 1 with an anti-jamming structure.

[0026] A drive motor 2 is installed on the left side of the screw conveyor body 1. A drive rod 3 is installed inside the drive motor 2. A protective cover 5 is installed on the right side of the drive motor 2. A screw rod 6 is installed inside the protective cover 5. The screw rod 6 is connected to the drive rod 3 by a flange. A feed inlet 7 and a discharge outlet 8 are respectively installed on the top two sides of the protective cover 5.

[0027] There is a sliding sleeve 9 on the outer side of the screw rod 6, a screw 16 is provided inside the sliding sleeve 9, and a screw conveyor blade 10 is provided on the outer side of the sliding sleeve 9.

[0028] The inner side of the sliding sleeve 9 is provided with a ring array of nesting parts 18, and the outer side of the screw 16 is provided with a ring array of sliding grooves 17.

[0029] The nested part 18 is nested with the slide groove 17, and the sliding sleeve 9 and the screw 16 are slidably connected through the nested part 18 and the slide groove 17.

[0030] Limiting rings 11 are provided on the left and right sides of the sliding sleeve 9, and nesting parts 18 are also provided inside the limiting rings 11. Fixing holes 19 are arranged in an array inside the screw 16, and limiting holes 15 are arranged in an annular array outside the limiting rings 11.

[0031] Fixing bolts 20 are provided inside the fixing hole 19 and the limiting hole 15, and the limiting ring 11 and the screw 16 are fixedly connected by the fixing bolts 20.

[0032] Mounting rings 13 are provided on the left and right sides of the sliding sleeve 9, and mounting sleeves 22 are provided on the outer side of the mounting rings 13. Mounting sleeves 22 are also provided on the outer side of the limiting ring 11. A telescopic cloth 12 is provided in the middle of the limiting ring 11 and the mounting ring 13.

[0033] The mounting ring 13 and the limiting ring 11 are provided with mounting holes 14 in an outer ring array. Mounting bolts 21 are provided inside the mounting holes 14. The two ends of the telescopic cloth 12 are fixed by the mounting bolts 21 and the mounting sleeves 22.

[0034] The telescopic fabric 12 is made of high-density polyester woven fabric, and dust covers 4 are provided on the outer side of the transmission rod 3 and the screw rod 6.

[0035] In this embodiment, the specific implementation steps of a screw conveyor with an anti-jamming structure are as follows: The drive motor 2 is turned on, and the drive motor 2 drives the drive rod 3 to rotate. Since the screw rod 6 is flange-connected to the drive rod 3, the screw rod 6 rotates accordingly. Material enters the protective cover 5 from the feed inlet 7. The sliding sleeve 9 on the outer side of the screw rod 6 rotates together with the screw rod 6. During the rotation, the screw conveying blade 10 on the outer side of the sliding sleeve 9 pushes the material towards the discharge outlet 8. During the material conveying process, if local material blockage or significant resistance is encountered, the sliding sleeve 9 will slide in the groove 17 on the outer side of the screw 16 through the inner nesting part 18 to adapt to changes in resistance, preventing the screw conveying blade 10 from being jammed and ensuring continuous material conveying. Under the push of the screw conveying blade 10, the material is finally discharged from the discharge outlet 8, completing the material conveying process. The feed inlet 7, discharge outlet 8, and the inside of the protective cover 5 should be cleaned regularly to prevent material accumulation from affecting the next use of the equipment. Material adhering to the surface of the telescopic cloth 12 should also be cleaned, and if the telescopic cloth 12 is damaged, it should be replaced promptly.

[0036] like Figure 1-3 As shown, a sliding sleeve 9 is located on the outer side of the screw rod 6, and a screw 16 is located inside the sliding sleeve 9. A spiral conveying blade 10 is located on the outer side of the sliding sleeve 9. Nesting parts 18 are arranged in a ring array on the inner side of the sliding sleeve 9. A sliding groove 17 is arranged in a ring array on the outer side of the screw 16. The nesting parts 18 and the sliding groove 17 are nested together. The sliding sleeve 9 and the screw 16 are slidably connected through the nesting parts 18 and the sliding groove 17. Limiting rings 11 are provided on the left and right sides of the sliding sleeve 9. Nesting parts 18 are also provided inside the limiting rings 11. Fixing holes 19 are arranged in a ring array inside the screw 16. Limiting holes 15 are arranged in a ring array on the outer side of the limiting rings 11. Fixing bolts 20 are provided inside the fixing holes 19 and the limiting holes 15. The limiting rings 11 and the screw 16 are fixedly connected through the fixing bolts 20.

[0037] Preferably, the sliding sleeve 9 and the screw 16 are slidably connected to the groove 17 via the nesting part 18. When the screw conveyor encounters local blockage or large resistance during material conveying, the sliding sleeve 9 can slide relative to the screw 16. This feature effectively avoids the screw conveyor blade 10 being jammed by material, ensuring the continuity of material conveying, greatly improving the anti-jamming capability of the equipment, and reducing downtime and equipment damage risks caused by material jamming. The nesting part 18 inside the limiting ring 11 cooperates with the groove 17 on the screw 16. At the same time, the limiting ring 11 is fixedly connected to the screw 16 by the fixing bolt 20 passing through the fixing hole 19 and the limiting hole 15. This can accurately limit the sliding range of the sliding sleeve 9. This not only ensures the stable sliding of the sliding sleeve 9 during normal operation, but also prevents it from sliding excessively and detaching from the screw 16, thereby ensuring the stability of the entire screw conveyor structure and enabling the equipment to operate reliably for a long time. This modular and firmly connected structural design makes it easy to disassemble and install each component when the equipment malfunctions or needs maintenance, reducing maintenance costs and difficulties.

[0038] like Figure 4-5 As shown, mounting rings 13 are provided on the left and right sides of the sliding sleeve 9, and mounting sleeves 22 are provided on the outer side of the mounting rings 13. Mounting sleeves 22 are also provided on the outer side of the limiting ring 11. A telescopic cloth 12 is provided in the middle of the limiting ring 11 and the mounting ring 13. Mounting holes 14 are provided in an annular array on the outer side of the mounting rings 13 and the limiting ring 11. Mounting bolts 21 are provided inside the mounting holes 14. The two ends of the telescopic cloth 12 are fixed by the mounting bolts 21 and the mounting sleeves 22.

[0039] Preferably, the telescopic cloth 12 is installed between the limiting ring 11 and the mounting ring 13, which can effectively prevent material from leaking out from the gap between the sliding sleeve 9 and the limiting ring 11. During the material conveying process of the screw conveyor, this protective measure avoids material scattering, keeps the working environment clean, reduces material loss, and improves the efficiency and economy of material conveying. The mounting holes 14 on the outside of the mounting ring 13 and the limiting ring 11 cooperate with the mounting bolts 21 to firmly fix both ends of the telescopic cloth 12 through the mounting sleeves 22. This installation method is simple and direct, which is convenient for operators to operate during equipment assembly and maintenance. At the same time, the cooperation between the mounting bolts 21 and the mounting sleeves 22 can provide reliable fixing force to ensure that the telescopic cloth 12 will not loosen or fall off during equipment operation and maintain the sealing effect on the material for a long time.

[0040] like Figure 1-5 As shown, the telescopic fabric 12 is made of high-density polyester, and dust covers 4 are provided on the outer sides of the transmission rod 3 and the screw rod 6.

[0041] Optionally, high-density polyester material has high strength and wear resistance. The telescopic fabric 12 is made of this material and can withstand the friction of materials and the tensile force caused by the relative movement of parts in the complex working environment of the screw conveyor. It is not easily damaged, thus extending its own service life and that of the entire equipment. This reduces equipment maintenance costs and downtime caused by damage to the telescopic fabric. The dust cover 4 can effectively block external dust and impurities from entering the connection between the transmission rod 3 and the screw rod 6 and the working area of ​​the screw rod 6. The intrusion of dust and impurities may aggravate the wear of parts, affect transmission efficiency, and even lead to equipment failure. The dust cover 4 provides a protective barrier for the transmission rod 3 and the screw rod 6, extending the service life of these key components and reducing the failure rate of the equipment.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
