Description

Technical Field

[0001] This utility model relates to the field of anti-impact technology, specifically to an anti-impact device for a screw feeder. Background Technology

[0002] Screw feeders are widely used in building materials, metallurgy, chemical, power, coal, grain and other industries. They are suitable for conveying powdery, granular and small lump materials such as cement, coal powder, grain and fertilizer. They are not suitable for conveying materials that are easily perishable, highly viscous and easy to clump. However, when conveying materials with good flowability, screw feeders may experience problems such as material shoving or large fluctuations in metering accuracy. That is, when the drive stops, the material with good flowability will continue to flow forward rapidly due to inertia, making it difficult to control the discharge. Although it is currently possible to prevent material shoving by setting up double helices that intersect, the double helix design has a high cost for preventing shoving and a poor effect.

[0013] 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.

[0014] Please see Figures 1 to 4 An anti-impact device for a screw feeder includes an anti-impact cylinder 1, a support box 3, adjusting rods 4, adjusting components, elastic pads 5, and anti-impact plates 6. The anti-impact cylinder 1 is connected through the screw feeder body 2. The support box 3 is fixedly connected to one side of the anti-impact cylinder 1. Two adjusting rods 4 are provided, which are rotatably connected between the support box 3 and the anti-impact cylinder 1 with a staggered arrangement. The adjusting components are installed between the two adjusting rods 4. Two elastic pads 5 are provided, which are fixedly connected to the two adjusting rods 4 respectively, so as to facilitate stable contact with the inner wall of the anti-impact cylinder 1 and reduce material leakage. The anti-impact plates 6 are fixedly connected between each elastic pad 5 and the adjacent adjusting rod 4. The two anti-impact plates 6 are staggered vertically inside the anti-impact cylinder 1, and anti-wear pads 13 are fixedly connected to the sides of the two anti-impact plates 6 that are close to each other. When the two anti-impact plates 6 rotate to the staggered contact, the two anti-wear pads 13 can reduce the collision and wear between the two anti-impact plates 6.

[0015] refer to Figure 2 as well as Figure 3The adjustment assembly includes a dual-head motor 7, adjusting screws 8, adjusting cylinders 9, adjusting bars 10, adjusting gear plates 11, and adjusting gears 12. The dual-head motor 7 is mounted on the inner wall of the support box 3. A heat dissipation hole for the dual-head motor 7 is provided on one side of the support box 3. Two adjusting screws 8 are symmetrically connected to the dual-head motor 7. The dual-head motor 7 is configured to drive the two adjusting screws 8 to rotate in both directions, and the two adjusting screws 8 have threads in opposite directions. Two adjusting cylinders 9 are threadedly connected to the two adjusting screws 8 respectively. The initial positions of the two adjusting screws 8 are symmetrical. The adjusting bar 10 is fixedly connected to each adjusting cylinder 9. The adjusting tooth plate 11 is fixedly connected to each adjusting bar 10. There are two adjusting gears 12. The two adjusting gears 12 are fixedly connected to the two adjusting rods 4 respectively. The two adjusting tooth plates 11 are provided with multiple tooth grooves that match the adjusting gears 12. Limiting blocks 14 are fixedly connected to both the adjusting bar 10 and the adjusting tooth plate 11. The inner side wall of the support box 3 is provided with a limiting groove for the limiting block 14 to slide, which increases the stability of the adjusting bar 10 and the adjusting tooth plate 11 sliding in the support box 3. When the dual-head motor 7 is started, it drives the two adjusting screws 8 to rotate, which causes the two adjusting cylinders 9 to move the two adjusting bars 10 simultaneously. At the same time, the two adjusting bars 10 drive the two adjusting gear plates 11 to move simultaneously. Through the adjusting gear plates 11 and multiple tooth grooves, when the adjusting gear plates 11 move, they can drive the adjacent adjusting gears 12 to rotate, which in turn drives the adjusting rod 4 to rotate. This causes the adjusting rod 4 to drive the elastic pad 5 and the anti-impact plate 6 to rotate. As the two anti-impact plates 6 gradually approach each other, the gap between the two anti-impact plates 6 gradually decreases, so as to facilitate the adjustment of the anti-impact range. When both anti-impact plates 6 are rotated to the vertical position, the material in the anti-impact cylinder 1 can be blocked through the staggered cooperation of the two anti-impact plates 6 and the two anti-wear pads 13, thereby preventing the material from being impacted.

[0016] refer to Figure 1 The top of the anti-impact material cylinder 1 is detachably connected to a sealing plate 15. Multiple sealing brackets 16 are fixedly connected to the sealing plate 15. Each of the multiple sealing brackets 16 is threadedly connected to the anti-impact material cylinder 1 with a sealing screw 17. After the sealing plate 15 is installed on the top of the anti-impact material cylinder 1, multiple sealing brackets 16 will be placed on the anti-impact material cylinder 1. At the same time, multiple sealing screws 17 are tightened between the anti-impact material cylinder 1 and the multiple sealing brackets 16, which can increase the stability of the sealing plate 15 installed on the anti-impact material cylinder, thereby providing a stable seal for the inside of the anti-impact material cylinder 1.

[0017] refer to Figure 1A door 18 is detachably connected to one side of the support box 3. A connecting bracket 19 is fixedly connected to the door 18. Two connecting screws 20 are symmetrically threaded between the connecting bracket 19 and the support box 3. After the door 18 is installed on the support box 3, the two connecting screws 20 are tightened between the connecting bracket 19 and the support box 3. This allows the connecting bracket 19 and the door 18 to be stably installed on the support box 3, which is convenient for protecting the dual-head motor 7 and the adjusting gear 12. When the dual-head motor 7 needs to be repaired, the door 18 can be directly removed from the support box 3.

[0018] In summary, when both anti-impact plates 6 are in a horizontal position, the anti-impact device for the screw feeder will not affect the material conveying of the screw feeder body 2 and the anti-impact cylinder 1. When anti-impact is required, the double-headed motor 7 is started according to the anti-impact requirement, so that the two adjusting cylinders 9 can move by rotating the two adjusting screws 8, so that the two adjusting bars 10 can drive the two adjusting gear plates 11 to move, thereby causing the two adjusting gears 12 to drive the two adjusting rods 4 to rotate. When the two adjusting rods 4 drive the two elastic pads 5 and the two anti-impact plates 6 to rotate, so that the two anti-impact plates 6 are close to each other, the anti-impact range can be adjusted to adjust the material discharge range. When both anti-impact plates 6 are rotated to a vertical position and the two anti-wear pads 13 are in contact, a closed barrier can be formed in the anti-impact cylinder 1, thereby preventing the material from being impacted.
