Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and in particular to a buffer-type dustproof material guiding device. Background Technology

[0002] Belt conveyors play a vital role in mining, power, and coking industries. As continuous transport equipment, they are widely used due to their ease of installation and dismantling, large transport capacity, long belt service life, and convenient maintenance. However, traditional belt conveyors use fixed coal retaining plates, which need to be welded to the conveyor frame on-site according to the existing coal chute structure. These plates cannot effectively reduce the impact and wear of transported materials during feeding, nor can they properly adjust the material supply, easily leading to material accumulation. This can cause belt misalignment, slippage, and even belt tearing or breakage, posing a safety hazard and highlighting the shortcomings of traditional fixed coal retaining plates. Summary of the Invention

[0003] The purpose of this invention is to provide a buffered dustproof material guiding device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A buffer-type dustproof material guiding device includes a support base, dovetail guide rails, mounting holes, a lifting base, straight guide rails, smooth rods, adjusting bolts, compression springs, and a contact part. Vertical dovetail guide rails are fixed at both the front and rear ends of the inner wall of the support base, and multiple mounting holes penetrate both the front and rear parts in the front-rear direction. The two dovetail guide rails are slidably connected to the lifting base. Horizontal straight guide rails are fixed at both the front and rear ends of the inner wall of the lifting base in the left-right direction, and vertical smooth rods are fixed at both the front and rear ends of the top. A vertical adjusting bolt is rotatably connected to the upper middle part of the lifting base. The two smooth rods are slidably connected to the support base in the front-rear direction. The adjusting bolt is threadedly connected to the upper middle part of the support base. Multiple compression springs are fixed from front to back along the left-right direction on the upper left end of the lifting base. The lifting base also has a contact part.

[0006] Based on the above technical solution, the contact part includes a sliding seat, a protective cover, a through groove, a contact plate, a receiving groove, a baffle, a support shaft, and rollers. The two straight guide rails are slidably connected to a horizontal sliding seat. A vertical protective cover is fixed to the left side of the sliding seat, and a through groove is provided in the lower right part. The bottom of the protective cover is connected to the through groove. The left and upper and lower parts of the protective cover are penetrating. A vertical contact plate is attached and fixed to the right end of the inner wall of the protective cover. The right end of the protective cover is fixed to the left end of the compression spring. Vertical receiving grooves are penetrating the front and rear parts of the sliding seat. Baffles are slidably connected to the two receiving grooves. Horizontal support shafts are fixed to the left and right sides of the two baffles in the front and rear directions. Rollers are coaxially fixed to each support shaft.

[0007] Based on the above technical solution, when the adjusting bolt rotates, it can drive the lifting seat to slide up and down along the dovetail guide rail. The bottom end of the outer circumference of the roller is lower than the bottom end of the baffle. The contact plate is a UPF plate.

[0008] Compared with the prior art, the present invention has the following advantages: The present invention, through the cooperation of the protective cover and the compression spring, enables the protective cover to move to the right when squeezed by the material, thereby playing a certain buffering role and allowing the material to enter the passage groove. Furthermore, the space between the passage groove and the upper surface of the belt can be adjusted by rotating the adjusting bolt, thereby changing the material output and avoiding the accumulation of material that causes large-scale wear of the belt conveyor. The contact plate not only has strong shock energy absorption and friction noise reduction performance, but also has high wear resistance and good self-lubricating properties, thereby reducing impact, reducing wear, and extending service life.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-3As shown, a buffer-type dustproof material guiding device includes a support base 1, dovetail guide rails 2, mounting holes 3, a lifting seat 4, a straight guide rail 5, a smooth rod 6, adjusting bolts 7, a compression spring 8, and a contact part 9. Vertical dovetail guide rails 2 are fixed to the front and rear ends of the inner wall of the support base 1, and multiple mounting holes 3 penetrate the front and rear parts in the front-rear direction. The dovetail guide rails 2 effectively prevent the lifting seat 4 from moving left or right relative to the support base 1, avoiding the lifting seat 4 from disengaging from the sliding connection with the dovetail guide rails 2. The two dovetail guide rails 2 are slidably connected vertically to the lifting seat 4. The lifting seat 4 has horizontal straight guide rails 5 fixed at both ends of its inner wall in the left and right directions, and vertical guide rods 6 fixed at both ends of its top. The upper part of the lifting seat 4 is rotatably connected to a vertical adjusting bolt 7. The two guide rods 6 are slidably connected to the support seat 1 to improve the stability of the lifting seat 4 during the up and down sliding process. The adjusting bolt 7 is threadedly connected to the upper part of the support seat 1. Multiple compression springs 8 are fixed from front to back along the left and right directions on the upper left end of the lifting seat 4. The lifting seat 4 is also equipped with a contact part 9.

[0015] The contact portion 9 includes a sliding seat 10, a protective cover 11, a passage groove 12, a contact plate 13, a receiving groove 14, a baffle 15, a support shaft 16, and a roller 17. The two straight guide rails 5 are slidably connected to the horizontal sliding seat 10. A vertical protective cover 11 is fixed to the left side of the sliding seat 10, and a passage groove 12 is provided on the lower right side. The bottom of the protective cover 11 communicates with the passage groove 12. The left and upper / lower parts of the protective cover 11 are through-through. A vertical contact plate 13 is fixedly attached to the right end of the inner wall of the protective cover 11. The right end of the protective cover 11 is fixed to the left end of the compression spring 8. The sliding seat 10 has vertical receiving grooves 14 running through its front and rear parts. The two receiving grooves 14 are slidably connected to baffles 15. The cooperation of the baffles 15, the passage groove 12 and the protective cover 11 can block the dust generated when the material enters the passage groove 12 to a certain extent, reducing environmental pollution. The two baffles 15 have horizontal support shafts 16 fixed in the front and rear directions on their left and right sides. Each support shaft 16 is coaxially fixed with a roller 17.

[0016] When the adjusting bolt 7 rotates, it can drive the lifting seat 4 to slide up and down along the dovetail guide rail 2. The bottom end of the outer circumference of the roller 17 is lower than the bottom end of the baffle 15. The rolling friction between the roller 17 and the belt surface can control the stability of the height of the baffle 15, while avoiding contact between the baffle 15 and the belt and causing wear. The contact plate 13 is a UPF plate.

[0017] The working principle of this invention is as follows: During use, bolts are passed through the mounting holes 3 to install and fix the support base 1 onto the frame of the belt conveyor, ensuring the lifting seat 4 is directly above the belt and the left side of the protective cover 11 faces the material inflow direction. Under gravity, the baffle 15 descends, causing the roller 17 to roll and rub against the upper surface of the belt. When the conveying mechanism feeds material onto the belt of the belt conveyor, the material is blocked by the protective cover 11 and the contact plate 13, and simultaneously transported by the belt to the through trough 12, thus controlling the output. The descending baffle 15 effectively prevents material from overflowing from the baffle 15 when entering the through trough 12. To prevent environmental pollution caused by material overflowing from the upper surface of the belt, the contact between the material at the cover 11 and the contact plate 13 allows the compression spring 8 to elastically contract, which can play a buffering role and prevent the accumulation of material from causing large-scale wear on the belt conveyor. The UPF contact plate 13 not only has strong shock energy absorption and friction noise reduction performance, but also has high wear resistance and good self-lubrication, thereby reducing impact, reducing wear, and extending service life. By rotating the adjusting bolt 7, the lifting seat 4 can be driven to slide up and down, thereby adjusting the vertical height of the sliding seat 10, and thus changing the size of the space between the through groove 12 and the upper surface of the belt, thereby realizing the adjustment of the output.

[0018] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
