Description

Technical Field

[0001] This utility model relates to the field of horn-shaped idlers, and in particular to a horn-shaped idler for a belt conveyor. Background Technology

[0002] Horn-shaped idlers are a special type of idler mainly used for support and guidance of belt conveyors. One or both ends of the horn-shaped idler are horn-shaped. This design helps to center the conveyor belt and prevent it from running off-center. Belt conveyors, often simply referred to as belt conveyors, are a type of mechanical equipment widely used for material handling.

[0003] In practical use, some flared idlers are made of nylon or polyethylene. Flared idlers made of this material have high wear resistance and high corrosion resistance. Compared with flared idlers made of metal or other materials, nylon or polyethylene flared idlers can maintain stable operation for a longer period of time in harsh working environments.

[0004] Existing nylon or polyethylene horn-shaped idlers typically have a hollow horn section. Some horn-shaped idlers operate under the sun for extended periods, and the aging of the nylon or polyethylene material surface is accelerated by wind and sun exposure, making the surface brittle and causing the horn section structure to weaken and crack. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a horn-shaped idler for a belt conveyor, which can solve the following technical problems: the horn part of the existing nylon or polyethylene horn-shaped idler usually adopts a hollow structure. Some horn-shaped idlers will work under the sun for a long time. The aging of the nylon or polyethylene material surface is accelerated by wind and sun exposure, making the surface brittle, which leads to a decrease in the structural strength of the horn part of the horn-shaped idler and cracking.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a horn-shaped idler for a belt conveyor, comprising a roller and an intermediate idler fixed in the middle of the roller. Two sleeves located on both sides of the intermediate idler are sleeved on the outer side of the roller. Multiple T-shaped guide grooves are opened on the outer side of the sleeves. A detachable horn-shaped idler is sleeved on the outer side of the sleeves. The horn-shaped idler has a reinforcing rib structure inside. The reinforcing rib structure is connected to the T-shaped guide grooves by T-shaped locking blocks. A side plate is sleeved on the outer side of the roller for sealing and blocking the interior of the horn-shaped idler support. A retaining strip passes through the outer side of the roller to fix the position of the side plate.

[0007] As a preferred embodiment of this utility model, a keyway is provided on the outer side of the roller, and a key bar is provided in the keyway. The sleeve copper rotates synchronously with the roller through the key bar.

[0008] As a preferred embodiment of this utility model, the inner hole of the side plate is provided with a slot for engaging with the key bar.

[0009] As a preferred technical solution of this utility model, the horn roller support includes four first roller outer arc surfaces, which can form a complete horn shape. The inner side of the first roller outer arc surface is provided with a reinforcing rib structure, which includes two first reinforcing ribs located at the edge of the first roller outer arc surface, and the other end of the two first reinforcing ribs is connected to the inner arc surface of the roller.

[0010] As a preferred embodiment of this utility model, two T-shaped guide grooves are fixed at both ends of the inner arc surface of the roller.

[0011] As a preferred embodiment of this utility model, the trumpet roller support includes a complete outer arc surface of the second roller. A conical block is integrally formed at the small diameter position of the outer arc surface of the second roller. A T-shaped locking block is provided on the inner side of the conical block. The reinforcing rib structure includes a second reinforcing rib and a supporting arc block. The supporting arc block is fixed on the inclined surface of the second reinforcing rib. The supporting arc block is in contact with the inner wall of the outer arc surface of the second roller.

[0012] As a preferred embodiment of this utility model, the bottom of the second reinforcing rib is fitted to the outer side of the sleeve, and a T-shaped locking block is fixed to the bottom of the second reinforcing rib.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] 1. The belt conveyor is supported and guided by a detachable horn roller set on the outside of the sleeve. The horn roller is detachable by the cooperation of T-shaped guide groove and T-shaped clamp. The large diameter end of the horn roller is blocked and supported by side plate and clamp strip. At the same time, the strength of the horn roller is guaranteed by the reinforcing rib structure, which increases the service life.

[0015] 2. By dividing the horn roller into four outer arc surfaces of the first roller and forming an integral module with two first reinforcing ribs and one inner arc surface of the roller, the strength of the outer arc surface of the first roller is increased, and the first reinforcing ribs are made into a reinforcing rib structure. By decomposing the entire horn roller into four parts, the damaged part can be replaced after a single part is damaged, thus saving costs.

[0016] 3. The second reinforcing rib supports the outer arc surface of the second idler roller, and the supporting arc block expands the supporting surface, thereby improving the strength of the outer arc surface of the second idler roller. Through the design of the entire outer arc surface of the second idler roller and the separable reinforcing rib structure, the easily damaged outer arc surface of the second idler roller can be replaced, and the less easily damaged second reinforcing rib and supporting arc block can be reused.

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort. Example 1

[0026] Please refer to Figures 1-4As shown, this utility model provides a horn-shaped idler for a belt conveyor, including a roller 1, an intermediate idler 5 fixed in the middle of the roller 1, and two sleeves 9 at both ends of the outer side of the roller 1. The sleeves 9 are detachable and are fitted onto the outer side of the roller 1. The two sleeves 9 are located on both sides of the intermediate idler 5. A keyway is provided on the outer side of the roller 1, and a key bar 6 is provided in the keyway. The key bar 6 can cooperate with the slots inside the sleeves 9 to enable synchronous rotation between the sleeves 9 and the roller 1. Four T-shaped guide grooves 10 are provided on the outer side of the sleeves 9, and four first idler outer arc surfaces 4 are provided on the outer side of the sleeves 9. Two first reinforcing ribs 7 are provided at the edges of the first idler outer arc surfaces 4, and an inner arc surface 8 of the idler is provided at the bottom of the two first reinforcing ribs 7. The inner arc surface 8 of the idler roller is in contact with the outer side of the sleeve 9, and two T-shaped blocks 11 are fixed on the inner arc surface of the inner arc surface 8 of the idler roller. The T-shaped blocks 11 can engage with the T-shaped guide groove 10, so that the outer arc surface 4 of the first idler roller can only move along the axial direction of the sleeve 9. The outer edge of the outer arc surface 4 of the first idler roller extends outward to accommodate the side plate 2. After the side plate 2 is fitted on the outer side of the roller 1, the side plate 2 can fit with the inner wall of the outer arc surface 4 of the first idler roller, thereby supporting the large diameter end of the outer arc surface 4 of the first idler roller through the side plate 2. A keyway is opened on the inner hole of the side plate 2 to cooperate with the key strip 6. A retaining strip 3 passes through the outer side of the roller 1. The retaining strip 3 is an L-shaped iron piece. The long end of the retaining strip 3 can be bent after passing through the roller 1.

[0027] Specific working principle: During assembly, the sleeve 9 is placed on the outside of the roller 1, and after aligning the sleeve 9 with the key strip, the sleeve 9 is pushed to contact the intermediate idler roller 5. The outer arc surface 4 of the first idler roller is moved so that the T-shaped locking block 11 at the bottom of the inner arc surface 8 of the idler roller engages with the T-shaped guide groove 10, allowing the T-shaped locking block 11 to slide to the end of the T-shaped guide groove 10 and contact the intermediate idler roller 5. At this time, the small end of the outer arc surface 4 of the first idler roller is completely covered by the outside of the sleeve 9. After assembling and positioning the other three outer arc surfaces 4 of the first idler rollers according to the same steps, the side plate 2 is moved so that the slot of the side plate 2 engages with the key strip 6, and the side plate 2 is embedded into the interior of the outer arc surface 4 of the first idler roller. Then, the locking strip 3 passes through the roller 1 to fix the position of the side plate 2. After fixing, the side plate 2 is tightly attached to the sleeve 9, and the sleeve 9 is tightly attached to the intermediate idler roller 5, making the trumpet-shaped idler roller a stable whole.

[0028] The above structure divides the entire horn structure into four parts, so that if a part of the horn structure is damaged, only the damaged part needs to be replaced, thus saving costs. Furthermore, the first reinforcing rib 7 supports the outer arc surface 4 of the first idler roller, increasing the overall strength of the horn idler roller. Example 2

[0029] Please refer to Figure 1 , Figures 5-7As shown, this utility model provides a horn-shaped idler roller for a belt conveyor, including a roller 1, an intermediate idler roller 5 fixed in the middle of the roller 1, and two sleeves 9 at both ends of the outer side of the roller 1. The sleeves 9 are detachable and are fitted onto the outer side of the roller 1. The two sleeves 9 are located on both sides of the intermediate idler roller 5. A keyway is formed on the outer side of the roller 1, and a key bar 6 is provided in the keyway. The key bar 6 can cooperate with the slots inside the sleeves 9 to make the sleeves 9 and the roller 1 rotate synchronously. Four T-shaped guide grooves 10 are formed on the outer side of the sleeves 9. The outer arc surface 12 of the second idler roller is fitted onto the outer side of the sleeves 9. A conical block 15 is fixed inside the small-diameter end of the outer arc surface 12 of the second idler roller. The conical block 15 fits onto the outside of the sleeve 9 and can conform to the sleeve 9. Four T-shaped locking blocks 11 are fixed inside the conical block 15. After the T-shaped locking blocks 11 engage with the T-shaped guide grooves 10, the small-diameter end of the outer arc surface 12 of the second idler roller can be stably fitted onto the outside of the sleeve 9. A second reinforcing rib 13 is provided inside the outer arc surface 12 of the second idler roller. The bottom of the second reinforcing rib 13 is arc-shaped, and its cross-sectional diameter is the same as the outer diameter of the sleeve 9. A T-shaped locking block 11 is fixed at the bottom of the second reinforcing rib 13. Figure 7 As shown, the longitudinal section of the second reinforcing rib 13 is a right trapezoid. One side of the second reinforcing rib 13 can contact the conical block 15, and the hypotenuse of the second reinforcing rib 13 can fit against the inner wall of the outer arc surface 12 of the second idler roller. A supporting arc block 14 is fixed on the surface where the second reinforcing rib 13 fits against the outer arc surface 12 of the second idler roller. The supporting arc block 14 increases the supporting area of ​​the second reinforcing rib 13. A side plate 2 is sleeved on the outer side of the roller 1. The side plate 2 can be embedded into the large diameter end of the outer arc surface 12 of the second idler roller, thereby supporting the large diameter end of the outer arc surface 12 of the second idler roller through the side plate 2. A keyway is opened on the inner hole of the side plate 2 to cooperate with the key strip 6. A retaining strip 3 passes through the outer side of the roller 1. The retaining strip 3 is an L-shaped iron piece. The long end of the retaining strip 3 can be bent after passing through the roller 1.

[0030] Specific working principle: During assembly, the sleeve 9 is placed on the outside of the roller 1, aligning the sleeve 9 with the key strip. The sleeve 9 is then pushed to contact the intermediate roller 5. The outer arc surface 12 of the second roller is moved, causing the T-shaped locking block 11 on the inner side of the conical block 15 to engage with the T-shaped guide groove 10. The outer arc surface 12 of the second roller is then pushed, causing the T-shaped locking block 11 to slide to the end of the T-shaped guide groove 10, bringing the T-shaped locking block 11 into contact with the intermediate roller 5. The second reinforcing rib 13 is then moved, causing the T-shaped locking block 11 at the bottom of the second reinforcing rib 13 to engage with the T-shaped guide groove 10. The guide groove 10 engages, pushing the second reinforcing rib 13 until one end of the second reinforcing rib 13 contacts the conical block 15, and the supporting arc block 14 fits against the inner wall of the outer arc surface 12 of the second idler roller. The side plate 2 is moved so that the slot of the side plate 2 matches the key strip 6, and the side plate 2 is embedded into the interior of the T-shaped locking block 11. Then the locking strip 3 passes through the roller 1 to fix the position of the side plate 2. After fixing, the side plate 2 is tightly attached to the sleeve 9, and the sleeve 9 is tightly attached to the middle idler roller 5, making the trumpet-shaped idler roller a stable whole.

[0031] The above structure ensures that the outer arc surface 12 of the second idler roller as a whole can maintain stable strength. At the same time, the separable second reinforcing rib 13 allows the outer arc surface 12 of the second idler roller to be replaced after damage. The strength of the outer arc surface 12 of the second idler roller is increased by the support surface of the enlarged support arc block 14.
