Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor equipment, specifically relating to an adjustable head cover for a belt conveyor and the belt conveyor thereof. Background Technology

[0002] Belt conveyors are widely used material conveying equipment in industries such as mining, ports, power plants, chemicals, and building materials, primarily for transporting various bulk materials. During operation, the head area of ​​a belt conveyor is a critical part of material unloading. Equipment components in this area, such as drive rollers and idler rollers, are easily affected by material impact, wear, and external environmental factors (such as dust, moisture, and debris), leading to equipment failure, reduced service life, and increased maintenance costs. Furthermore, inadequate protection of the head area can also cause material splashing and spillage, resulting in environmental pollution and material waste.

[0003] The patent application number "CN219193839U" describes an easily adjustable protective cover for a mineral conveyor, comprising: a main body of the protective cover; two control mechanisms rotatably mounted on one side of the main body of the protective cover; and a positioning mechanism that penetrates the control mechanism. This invention addresses the use of mineral conveyors to transport crushed stone materials. To prevent the crushed stone from flying and colliding during the rotation of the conveyor rollers, the entire protective cover is first installed on the mineral conveyor using the positioning mechanism. The length of the entire protective cover is then adjusted using the control mechanism as needed. This allows for maintenance or repair of the mineral conveyor without disassembling the entire protective cover; the length can be shortened using the control mechanism. Furthermore, the protective cover can be shortened at both ends as needed, facilitating maintenance or repair of the mineral conveyor.

[0004] The above-mentioned technical solutions have certain limitations in use. Their size and shape are adapted to specific models of conveyors, resulting in poor versatility. When replacing conveyors of different specifications, the protective cover needs to be redesigned and manufactured, increasing costs and extending installation and maintenance time. In addition, the fixed structure cannot be flexibly adjusted according to actual working conditions such as material particle size, conveying speed, and unloading angle, making it difficult to effectively protect the head area. For example, when conveying large-particle materials, it is difficult to resist impact, causing damage to components such as rollers. When the conveying speed is high or the unloading angle changes, it cannot completely cover the unloading area, causing material to splash. Utility Model Content

[0036] 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.

[0037] Please see Figures 1 to 4 As shown, this embodiment of the utility model provides an adjustable head cover for a belt conveyor, specifically including two support bases 1, a flexible folded cover 7, and an adjustment mechanism. Each of the two support bases 1 has a limiting groove 18 at its top. Two second moving blocks 13 are slidably connected within each limiting groove 18. A fixing plate 19 is fixedly connected to the top of each of the four second moving blocks 13. A first connecting plate 3 is fixedly connected to the adjacent ends of each of the four fixing plates 19. Two slide rails 2 are fixedly connected to the adjacent ends of each of the four first connecting plates 3, with each pair of first connecting plates 3 corresponding to one slide rail 2. The flexible folded cover 7 is positioned between the two support bases 1, and a dustproof cover 17 is fixedly connected to the bottom of the flexible folded cover 7. The adjustment mechanism is positioned between the two support bases 1 and is used to adjust the length of the flexible folded cover 7.

[0038] In this specific embodiment, the two support bases 1 serve as the basic load-bearing components of the entire protective cover structure, playing a crucial role in providing stable support. The limiting groove 18 at their top provides a sliding track for the second moving block 13. Through the constraint of the limiting groove 18, the second moving block 13 is ensured to move stably in the horizontal direction, limiting its displacement in other directions, ensuring the stability and accuracy of the structure during the adjustment process, thereby laying a reliable foundation for the adjustment function of the entire protective cover.

[0039] The main function of the limiting groove 18 is to guide and limit the sliding of the second moving block 13. It works in conjunction with the second moving block 13 to ensure smooth sliding along the set path, preventing deviation or wobbling during movement, thus guaranteeing the accuracy and stability of the cover adjustment process. It also enhances the connection strength and reliability of the entire structure. The second moving block 13 is a key transmission component for realizing the cover adjustment function. It slides within the limiting groove 18, and its movement drives the synchronous movement of connected components such as the fixed plate 19, the first connecting plate 3, and the slide rail 2, thereby achieving adjustment of the width or length of the flexible folding cover 7. It is an important medium for transmitting the movement of the adjustment mechanism to the main structure of the cover.

[0040] The fixed plate 19 serves a connecting and fixing function. It firmly connects the second moving block 13 to the first connecting plate 3, ensuring that the movement of the second moving block 13 can be reliably transmitted to the first connecting plate 3, guaranteeing the connection stability between the components, and at the same time enhancing the rigidity of the overall structure to a certain extent, ensuring that the structure will not easily deform during adjustment and use. The first connecting plate 3 is used to connect the fixed plate 19 and the slide rail 2, serving as an important bridge connecting different components in the protective cover structure. It further transmits the movement of the second moving block 13 to the slide rail 2, and structurally supports and fixes the slide rail 2, ensuring the positional stability of the slide rail 2 during adjustment, and providing stable support and guidance for the movement of the resilient folding protective cover 7. The slide rail 2 provides guidance and support for the movement of the resilient folding protective cover 7. The resilient folding protective cover 7 can move telescopically along the slide rail 2. Through the precise guidance of the slide rail 2, it is ensured that the resilient folding protective cover 7 can smoothly and easily unfold or retract during adjustment, and can withstand a certain amount of external force, ensuring the structural strength and stability of the protective cover during use, and preventing the resilient folding protective cover 7 from jamming or deforming during movement.

[0041] In this embodiment, the flexible folding cover 7 is the core component for head protection. It possesses excellent toughness and foldability, allowing its length and shape to be flexibly adjusted according to the actual size and operating conditions of the conveyor head area, providing comprehensive protection. It effectively blocks material impact and splashing, prevents dust diffusion, and adapts to different specifications and models of conveyors, meeting diverse protection needs. The dust cover 17 is fixedly connected to the bottom of the flexible folding cover 7, primarily preventing dust and debris from entering the conveyor head area from the bottom of the cover, causing contamination and wear to equipment components. It further enhances the dustproof effect of the cover, protecting key components such as the drive rollers and idler rollers at the conveyor head, reducing the probability of equipment failure, extending equipment lifespan, and also helping to improve the working environment and reduce the health impact of dust on operators. The adjustment mechanism is the core component for realizing the adjustable function of the cover; its function is to adjust the length of the flexible folding cover 7 through a specific mechanical structure or power system. Based on the actual working conditions and the size requirements of the head area of ​​the belt conveyor, the adjustment mechanism can drive the second moving block 13 to slide in the limiting groove 18, thereby driving the various components connected to it to move, realizing the expansion or contraction of the flexible folding cover 7, so that the cover can adapt to belt conveyors of different specifications and different material conveying conditions, achieving the best protection effect.

[0042] It should be noted that the specific model of motor 20 used shall be selected by those skilled in the art, and the above-mentioned motor 20 and other related information are all existing technologies, which will not be elaborated upon in this solution.

[0043] Please see Figures 1 to 4 As shown, the adjustment mechanism specifically includes a limiting rod 15, a lead screw 4, a nut 6, a first moving block 5, and a positioning assembly. The limiting rod 15 is fixedly connected to the near ends of two first connecting plates 3 on the left side, and the resilient folding cover 7 is slidably connected to the limiting rod 15 and the circumferential surfaces of the two slide rails 2. The lead screw 4 is rotatably connected to the near ends of two first connecting plates 3 on the right side, and a motor 20 is fixedly connected to the rear end of one of the first connecting plates 3 on the right rear side. The output end of the motor 20 is fixedly connected to one end of the lead screw 4. Two nuts 6 are provided, and the two nuts 6 are respectively fixedly connected to the front and middle parts of one side end of the resilient folding cover 7. Two first moving blocks 5 are provided, and the two first moving blocks 5 are threadedly connected to the circumferential surface of the lead screw 4. The two first moving blocks 5 are respectively fixedly connected to the two nuts 6. The positioning assembly is provided in two limiting grooves 18, and the positioning assembly is used to accurately position the two second moving blocks 13, thereby realizing the adjustment of the width between the resilient folding covers 7.

[0044] Specifically, in this embodiment, when the length of the resilient folding cover 7 needs to be adjusted, the motor 20 is started, and the output shaft of the motor 20 drives the lead screw 4 to rotate. Since the first moving block 5 is threadedly connected to the lead screw 4, the rotational motion of the lead screw 4 is converted into the linear motion of the first moving block 5 along the axis of the lead screw 4. The first moving block 5 is connected to the resilient folding cover 7 through the nut 6, thereby driving the resilient folding cover 7 to extend and retract under the guidance of the limiting rod 15 and the slide rail 2, realizing the adjustment of the cover length. If the width of the resilient folding cover 7 needs to be adjusted, the positioning component is operated to change the position of the second moving block 13 in the limiting groove 18. When the second moving block 13 moves, it drives the fixed plate 19, the first connecting plate 3 and the slide rail 2 connected to it to move synchronously, thereby adjusting the distance between the two slide rails 2, realizing the change of the width of the resilient folding cover 7. Through the dual adjustment of length and width, this adjustable head cover can adapt to belt conveyors of different specifications and working conditions, providing good protection for the head area.

[0045] Please see Figures 1 to 3 As shown, the positioning assembly specifically includes an L-shaped second connecting plate 11, screws 12, and first plastic pads 14. Four L-shaped second connecting plates 11 are provided, each fixedly connected to one end of a pair of support bases 1. Four screws 12 are provided, each threadedly connected to one of the four L-shaped second connecting plates 11 and rotatably connected to one of the four second moving blocks 13. Two first plastic pads 14 are provided, each fixedly connected to the adjacent ends of the four screws 12.

[0046] Specifically, in this embodiment, when it is necessary to adjust the width of the flexible folding cover 7, the operator achieves this by rotating the screw 12. Since the screw 12 is threadedly connected to the L-shaped second connecting plate 11, according to the principle of threaded transmission, rotating the screw 12 will cause the screw 12 to move linearly along the axial direction. The linear movement of the screw 12 drives the second moving block 13, which is rotatably connected to it, to slide within the limiting groove 18 at the top of the support base 1. By controlling the rotation direction and number of rotations of the screw 12, the movement distance and direction of the second moving block 13 within the limiting groove 18 can be precisely controlled, thereby adjusting the distance between the two second moving blocks 13. The change in the distance between the two second moving blocks 13 will cause the fixed plate 19, the first connecting plate 3, and the slide rail 2 connected to it to move synchronously, ultimately achieving the adjustment of the width of the flexible folding cover 7. During the adjustment process, the first plastic pad 14 plays a role in buffering and increasing friction, ensuring the smoothness of the adjustment process and the stability of the position after adjustment.

[0047] Please see Figure 2As shown, a second plastic pad 16 is fixedly connected to the bottom end of each of the two support bases 1, and a label 10 is fixedly connected to one side of the flexible folding cover 7. The second plastic pad 16 fixedly connected to the bottom end of the two support bases 1 mainly serves to cushion and prevent slippage. The label 10 fixedly connected to one side of the flexible folding cover 7 facilitates the identification and management of the cover. In practical applications, belt conveyor head covers of different specifications and with different usage requirements may vary. The label 10 can indicate important information such as the cover model, applicable belt conveyor specifications, installation instructions, and maintenance cycle.

[0048] Please see Figures 1 to 4 As shown, a support block 9 is fixedly connected to the front end of the resilient folding protective cover 7, and a tension band 8 is rotatably connected inside the support block 9. The support block 9 fixedly connected to the front end of the resilient folding protective cover 7 and the tension band 8 rotatably connected inside it work together to enhance the adaptability and protective performance of the cover. When it is necessary to adjust the coverage area or shape of the cover, the operator can pull the tension band 8. The tension band 8, through its rotatable connection with the support block 9, can flexibly change the shape and position of the front end of the resilient folding protective cover 7. A limiting sleeve 21 is fixedly connected to the bottom end of the resilient folding protective cover 7, and the limiting sleeve 21 is fixedly connected to the outer surface of the two slide rails 2. The limiting sleeve 21 fixedly connected to the bottom end of the resilient folding protective cover 7 and the outer surface of the two slide rails 2 further optimizes the telescopic adjustment performance of the cover. The limiting sleeve 21 can be tightly fitted onto the outer surface of the slide rail 2. When the resilient folding protective cover 7 moves telescopically along the slide rail 2, the limiting sleeve 21 plays a guiding and limiting role, ensuring that the cover will not deviate or detach from the slide rail 2 during the movement, making the telescopic movement of the cover more stable and smooth.

[0049] Specifically, in this embodiment, when installing the adjustable head cover of the belt conveyor, the two support seats 1 are first stably installed in a suitable position in the head area of ​​the belt conveyor via the second plastic pad 16 at the bottom. The cushioning and anti-slip effect of the second plastic pad 16 ensures the stability of the support seats 1. If the width of the belt conveyor head does not match the initial width of the cover, the operator rotates the screws 12 on the L-shaped second connecting plates 11 at both ends of the support seat 1. The screws 12 move linearly along the axial direction through the threaded transmission with the L-shaped second connecting plates 11, driving the second moving blocks 13 rotatably connected to them to slide in the limiting groove 18. By controlling the rotation direction and number of turns of the screws 12, the distance between the two second moving blocks 13 is adjusted, thereby driving the fixed plate 19, the first connecting plate 3 and the slide rail 2 to move synchronously, realizing the adjustment of the width of the flexible folding cover 7. During the adjustment, the first plastic pad 14 plays a role in cushioning and increasing friction to ensure a smooth process and stable position. Based on the actual length requirements of the belt conveyor head area, motor 20 is started, driving screw 4 to rotate. The rotation of screw 4 causes the first moving block 5, which is threaded to it, to move linearly along the axis of screw 4. The first moving block 5, through nut 6, drives the flexible folding cover 7 to extend and retract under the guidance of limit rod 15 and slide rail 2, thereby adjusting the length of the cover. To further adjust the coverage area or shape of the cover, the tension belt 8 rotatably connected inside support block 9 can be pulled to change the shape and position of the front end of the cover. At the same time, the limit sleeve 21 at the bottom of the flexible folding cover 7 is tightly fitted onto the outer surface of slide rail 2, playing a guiding and limiting role when the cover extends and retracts, ensuring smooth and stable movement. In daily use, relevant information can be obtained through the label 10 on one side of the cover for maintenance and management. The dustproof cover 17 prevents dust and debris from entering the belt conveyor head area, protecting the equipment components.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
