Description
Technical Field
[0001] This utility model relates to the field of material conveying equipment technology, and in particular, to a side plate accumulation type buffer chute and buffer chute structure. Background Technology
[0002] Chutes are common material handling devices in industrial production, widely used in metallurgy, coal, transportation, power, building materials, chemical, light industry, grain, and machinery industries. In the metallurgical industry, when transferring materials between upper and lower belt conveyors, chutes are often used to transport materials to specific discharge points. The chutes may make one or more turns at intermediate points, such as... Figure 1 As shown, rapidly flowing material violently impacts the chute body (chute sidewall / impact surface liner) at the turning point. The material is conveyed within the chute and forms an impact surface, causing rapid wear on the chute sidewall. In existing technology, various liner plates are typically installed on the inner side of the chute (the inner side of the material receiving wall). However, the service life of the liner plates at the turning point is significantly shorter than that of the liner plates in other parts, especially when conveying materials with high hardness and large particle size. The impact wear on the impact surface liner plates is greater, making it easier to penetrate the liner plates or even the chute body, resulting in a significant increase in operating costs and maintenance.
[0003] Therefore, it is necessary to propose a side-plate accumulation type buffer chute and buffer chute structure to solve or at least alleviate some of the above-mentioned defects. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A side-plate accumulation buffer chute includes a chute body, which includes an upper guide section and a lower guide section that are interconnected. The upper guide section is located above the lower guide section and has an inclined chute. The top inlet of the upper guide section and the bottom outlet of the lower guide section are staggered. An accumulation buffer trough is arranged on the impact sidewall of the lower guide section opposite to the upper guide section. The accumulation buffer trough is interconnected with the bottom outlet.
[0007] Furthermore, the lower guide section includes a first guide shell and a side-opening buffer shell (buffer backpack). The first guide shell is located at the bottom of the upper guide section. A receiving opening is arranged on the receiving impact side wall of the first guide shell opposite to the upper guide section. The buffer shell is covered on the outside of the receiving impact side wall. The buffer shell has a material accumulation buffer groove, which is connected to the receiving opening.
[0008] Furthermore, the lower material guide section also includes a first material accumulation platform, which protrudes from the side wall of the buffer shell and forms a material accumulation auxiliary groove with the buffer shell.
[0009] Furthermore, the first material accumulation platform is located within the material accumulation buffer trough, the first material accumulation platform is arranged horizontally, and / or multiple first material accumulation platforms are distributed at intervals along the height direction.
[0010] Furthermore, the lower guide section includes a second guide shell and a second accumulation platform. The second guide shell is located at the bottom of the upper guide section. The second accumulation platform is arranged on the material impact sidewall opposite to the upper guide section. The second accumulation platform protrudes from the material impact sidewall and surrounds the material impact sidewall to form an accumulation buffer groove.
[0011] Furthermore, the second material accumulation platform is located within the channel of the second material guide shell, the second material accumulation platform is arranged horizontally, and / or multiple second material accumulation platforms are distributed at intervals along the height direction.
[0012] Furthermore, the second material accumulation platform includes a first material accumulation plate, a connecting mounting base, and a first supporting rib. The connecting mounting base is fixedly disposed on the inner wall surface of the material impact sidewall. The fixed end of the first material accumulation plate is supported on the connecting mounting base. The first end of the first supporting rib is disposed on the material impact sidewall or the connecting mounting base, and the second end of the first supporting rib extends outward to support the cantilever end of the first material accumulation plate.
[0013] Furthermore, the receiving side wall of the second material guide shell is provided with plate insertion holes extending along its width direction. The second material accumulation platform is arranged in a one-to-one correspondence with the plate insertion holes. The second material accumulation platform includes a second material accumulation plate, a connecting bolt, and a second support rib. The fixed end of the second material accumulation plate is inserted into the plate insertion hole and fixed by the connecting bolt.

[0016] This utility model has the following beneficial effects:
[0017] This utility model discloses a side-plate accumulation buffer chute and its structure, comprising a chute body, which includes an upper guide section and a lower guide section that are interconnected. The upper guide section is located above the lower guide section and is arranged at an inclination. The top inlet of the upper guide section and the bottom outlet of the lower guide section are staggered. An accumulation buffer trough is arranged on the impact-receiving sidewall of the lower guide section opposite to the upper guide section. The accumulation buffer trough is interconnected with the bottom outlet. When the material is guided by the side-plate accumulation buffer chute, the material changes direction in the guide trough after passing through the top inlet and is discharged from the bottom outlet. The initial material entering the lower guide section will accumulate and be stored in the accumulation buffer trough. Subsequent material entering the lower guide section will collide with the stored material and be discharged from the bottom outlet. This avoids the direct impact contact between the material and the impact-receiving sidewall of the lower guide section as in the prior art, thus extending the service life of the chute body.

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0034] 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.

[0036] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0037] Please refer to Figure 2 , Figure 3a , Figure 3b , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the present invention provides a side-plate accumulation buffer chute 100, which includes a chute body 10. The chute body 10 includes an upper guide section 20 and a lower guide section 30 that are connected to each other. The upper guide section 20 is located above the lower guide section 30 and has an inclined chute. The top inlet 201 of the upper guide section 20 and the bottom outlet 301 of the lower guide section 30 are staggered. An accumulation buffer groove 311 is arranged on the material impact sidewall 31 of the lower guide section 30 and the upper guide section 20, and the accumulation buffer groove 311 is connected to the bottom outlet 301.
[0038] This utility model provides a side-plate accumulation buffer chute 100, including a chute body 10. The chute body 10 includes an upper guide section 20 and a lower guide section 30 that are interconnected. The upper guide section 20 is located above the lower guide section 30 and is arranged at an inclination. The top inlet 201 of the upper guide section 20 and the bottom outlet 301 of the lower guide section 30 are staggered. An accumulation buffer groove 311 is arranged on the impact sidewall 31 of the lower guide section 30 opposite to the upper guide section 20. The accumulation buffer groove 311 and the bottom outlet 301 are connected. 1. The materials are interconnected. When the material is guided through the side plate accumulation buffer chute 100, the material changes direction in the guide chute after passing through the top inlet 201 and is discharged from the bottom outlet 301. When the initial material enters the lower guide section 30, it will be accumulated and stored in the accumulation buffer chute 311. When the subsequent material enters the lower guide section 30, it will collide with the stored material and be discharged from the bottom outlet 301. This avoids the direct impact contact between the material and the impact side wall 31 of the lower guide section 30 in the prior art, and extends the service life of the chute body 10.
[0039] More preferably, multiple material accumulation buffer grooves 311 are arranged at intervals on the material impact sidewall 31; a protective liner is attached to the inner side of the material impact sidewall 31. Further, multiple material accumulation buffer grooves 311 are evenly spaced on the material impact sidewall 31.
[0040] Understandably, in this invention, the upper guide section 20 is located above the lower guide section 30 and has an inclined chute. The lower guide section 30 has a vertical guide trough. During the process of material entering the vertical guide trough from the inclined guide trough, it will impact the material-receiving impact sidewall 31 of the vertical guide trough. Optionally, the upper guide section 20 and the lower guide section 30 can be circular structures, square structures, or other shapes.
[0041] Please refer to this again. Figure 2 In an optional embodiment of this utility model, the lower guide section 30 includes a first guide shell 32 and a buffer shell 33 with a side opening. The first guide shell 32 is located at the bottom of the upper guide section 20. A receiving opening is arranged on the receiving impact side wall 31 opposite to the upper guide section 20. The buffer shell 33 covers the outside of the receiving impact side wall 31 and has a material accumulation buffer groove 311, which is connected to the receiving opening. Understandably, in this utility model, the buffer shell 33 covers the outside of the receiving impact side wall 31 to form a backpack-type buffer liner. During the process of material entering the vertical guide chute from the inclined chute, the initial material accumulates inside the backpack and acts as a buffer pad for subsequent impacting materials, preventing subsequent materials from directly impacting the receiving impact side wall 31. This helps reduce wear on the receiving impact side wall 31 and improves its service life.
[0042] Optionally, the receiving opening can be an opening on the entire receiving side wall of the first material guide housing 32 (if it is an opening on the entire receiving side wall, it can be understood that the first material guide housing 32 does not have a receiving impact side wall 31), or it can be an opening on a part of the receiving side wall, with the receiving opening located at the upper part of the first material guide housing 32.
[0043] Please refer to this again. Figure 3a In an optional embodiment of the present invention, the lower guide section 30 further includes a first accumulation platform 34, which protrudes from the side wall of the buffer housing 33 and forms an auxiliary accumulation groove with the buffer housing 33.
[0044] Furthermore, the first material accumulation platform 34 is located within the material accumulation buffer trough 311, and the first material accumulation platform 34 is arranged horizontally. Understandably, the second material accumulation platform 36 can be arranged horizontally or inclined. When the second material accumulation platform 36 is arranged horizontally, it can store more material without prolonging the material conveying time.
[0045] Furthermore, multiple first material accumulation platforms 34 are distributed at intervals along the height direction.
[0046] For details, please refer to Figure 3b The first material accumulation platform has a fixed base, and the buffer shell 33 is provided with fixing holes. The fixed base and fixing holes are connected by fixing bolts. In actual production, the height of the fixed base can be adjusted by opening holes in the side plate shell according to the material unloading situation on site, thereby achieving the effect of adjusting the height of the first material accumulation platform 34.
[0047] Furthermore, the buffer housing 33 and the first feed housing 32 are connected by a flange.
[0048] The backpack-type buffer liner with side plate material accumulation buffer chute 100 provided in the above embodiments of this utility model can store more material during the feeding process and can more effectively prevent the falling material from directly contacting the impact side wall 31; and can be detached through flange cooperation, which facilitates maintenance and replacement of buffer shell 33 (buffer backpack).
[0049] Please refer to this again. Figure 4 In an optional embodiment of this utility model, the lower guide section 30 includes a second guide housing 35 and a second accumulation platform 36. The second guide housing 35 is disposed at the bottom of the upper guide section 20. The second accumulation platform 36 is arranged on the material impact sidewall 31 opposite to the upper guide section 20. The second accumulation platform 36 protrudes from the material impact sidewall 31 and surrounds the material impact sidewall 31 to form an accumulation buffer groove 311.
[0050] Furthermore, the second material accumulation platform 36 is located within the channel of the second material guide housing 35, and the second material accumulation platform 36 is arranged horizontally. Understandably, the second material accumulation platform 36 can be arranged horizontally or inclined. When the second material accumulation platform 36 is arranged horizontally, it can store more material without prolonging the material conveying time.
[0051] Furthermore, multiple second material accumulation platforms 36 are distributed at intervals along the height direction.
[0052] Preferably, three second material accumulation platforms are arranged in a flat configuration, or three first material accumulation platforms are arranged in a flat configuration.
[0053] Please refer to this again. Figure 5Furthermore, the second material accumulation platform 36 includes a first material accumulation plate 361, a connecting mounting base 362, and a first support rib 363. The connecting mounting base 362 is fixedly disposed on the inner wall surface of the material impact side wall 31. The fixed end of the first material accumulation plate 361 is supported on the connecting mounting base 362. The first end of the first support rib 363 is disposed on the material impact side wall 31 or the connecting mounting base, and the second end of the first support rib 363 extends outward to support the cantilever end of the first material accumulation plate.
[0054] Understandably, in the utility model, each first material accumulation plate 361 may have a corresponding connecting mounting seat 362; or all the first material accumulation plates 361 may share a side plate shell, in which case multiple connecting mounting seats 362 are combined to form a side plate shell, and the side plate shell is welded to the outer wall of the material impact side wall 31 or connected by a flange.
[0055] Optionally, in this utility model, the connecting mounting base 362 is fixed to the side of the material receiving impact by bolts.
[0056] More preferably, multiple first support ribs 363 are arranged at intervals along the width direction of the first material accumulation plate 361.
[0057] Please refer to this again. Figure 6 , Figure 7 , Figure 8 and Figure 9 In an optional embodiment of this utility model, the receiving side wall of the second material guide housing 35 is provided with a plate insertion hole 351 extending along its width direction. The second material accumulation platform is arranged in a one-to-one correspondence with the plate insertion hole 351. The second material accumulation platform 36 includes a second material accumulation plate 364, a connecting bolt 365 and a second support rib 366. The fixed end of the second material accumulation plate 364 is inserted into the plate insertion hole 351 and fixed by the connecting bolt 365. The first end of the second support rib 366 is provided on the receiving impact side wall 31, and the second end of the second support rib 366 extends outward to support the cantilever end of the first material accumulation plate.
[0058] Furthermore, the second material accumulation plate 364 is provided with multiple rows of pin holes, which are arranged at intervals along the length direction of the first material accumulation plate 361, and the connecting bolts 365 are arranged in a one-to-one correspondence with the pin holes.
[0059] More preferably, multiple second support ribs 366 are arranged at intervals along the width direction of the second material accumulation plate 364.
[0060] Furthermore, the bottom of the upper guide section 20 is stepped.
[0061] This patent solution provides two forms of the second material accumulation platform 36, as follows: Figure 5 and Figure 8 As shown; specifically, as Figure 5The second material accumulation platform 36 shown includes a first material accumulation plate 361, a connecting mounting base 362, and a first supporting rib 363. The connecting mounting base 362 is fixedly mounted on the inner wall of the impact side wall 31. The fixed end of the first material accumulation plate 361 is supported on the connecting mounting base 362. The first end of the first supporting rib 363 is located on the impact side wall 31 or the connecting mounting base, and the second end of the first supporting rib 363 extends outward to support the cantilevered end of the first material accumulation plate. The connecting mounting base 362 is connected to the side plate shell by fixing screws. The supporting rib is welded to the connecting mounting base 362, and the cantilevered end of the first material accumulation plate 361 is welded to the supporting rib. In actual production, holes can be opened in the side plate shell to adjust the installation height of the connecting mounting base 362 and fixing screws can be installed according to the material unloading situation on site, thereby achieving the effect of adjusting the installation spacing of the first material accumulation plate 361 in the height direction. Figure 8 The second material accumulation platform 36 shown includes a second material accumulation plate 364, a connecting bolt 365, and a second support rib 366. The fixed end of the second material accumulation plate 364 is inserted into the plate insertion hole 351 and fixed by the connecting bolt 365. The first end of the second support rib 366 is provided on the material impact side wall 31, and the second end of the second support rib 366 extends outward to support the cantilever end of the first material accumulation plate. A space is provided on the side plate outer shell (the material receiving side wall of the second material guide shell 35). The plate has rectangular insertion holes 351 through which the second material accumulation plate 364 can be inserted. The second support rib 366 is a right triangular prism, providing support for the second material accumulation plate 364. The second material accumulation plate 364 has pin holes arranged in two rows, with the row spacing slightly greater than the thickness of the side plate shell, to secure the second material accumulation plate 364. In actual production, the length of the second material accumulation plate 364 inserted into the chute can be adjusted according to the material feeding situation on site to regulate the amount of material accumulated on the buffer side plate. Figure 5 The second material accumulation platform 36 shown can adjust the height and length of the material accumulation platform, offering better adjustability; however, it requires on-site drilling and installation of fixing bolts, making it difficult to replace and maintain. Figure 8 The second material accumulation platform 36 shown can replace the material accumulation plate and adjust the length of the material accumulation plate more quickly, making it more suitable for transportation environments with varying materials. However, the height cannot be adjusted; the height of the material accumulation plate can only be determined by the material accumulation plate insertion hole 351 on the side plate outer shell.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
