Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a Y-type sealing assembly for a material guide trough. Background Technology

[0002] In the field of bulk material conveying, the sealing performance of the chute directly affects material conveying efficiency and environmental pollution control. Traditional chute systems mostly adopt fixed sealing structures, which suffer from problems such as high frictional resistance between the seal and the conveyor belt, severe belt wear, and high energy consumption. Although some technologies have attempted to achieve dynamic adjustment of contact pressure through spring buffering or adaptive adjustment mechanisms, such as the combination of guide rod and adjusting spring described in CN120397586A, their structures are still relatively complex, and their sealing effect on fine particles is limited. In particular, sealing failure or adjustment lag is prone to occur when materials are impacted or the belt deviates. In addition, existing seals are mostly single plate structures, which cannot meet the blocking requirements of materials with different particle sizes, and the height adjustment is inconvenient, affecting service life and adaptability.

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0018] See Figure 1-6 In one embodiment of this utility model, a Y-shaped sealing assembly for a material guide trough includes: a fixing frame and a sealing cover. The material guide trough includes a frame 11, a roller 12, and a conveyor belt 13 laid on the roller 12. The conveyor belt 13 is a U-shaped structure composed of a horizontal section and two inclined sections. The two inclined sections are located on both sides of the horizontal section, and the angle between the inclined sections and the horizontal plane is an acute angle θ. The sealing cover is installed above the material guide trough through the fixing frame and forms an upper and lower cooperation with the conveyor belt 13 to achieve the sealing of the outer perimeter of the material guide trough while ensuring that the inlet and outlet ends of the material guide trough are open.

[0019] Specifically, the fixing frame includes several fixing rods 2 and connecting plates 3. The fixing rods 2 are vertically arranged and their lower ends are fixedly connected to the frame 11. The connecting plates 3 are fixedly arranged at the top of the fixing rods 2.

[0020] The sealing cover has a rectangular cover structure with open ends along its length; the sealing cover is fixedly connected to the connecting plate 3; the sealing cover includes a top plate 5 and two sets of side baffle assemblies, which are symmetrically arranged at both ends of the top plate 5 in the width direction. The side baffle assembly includes a side baffle 4, an anti-overflow skirt 6, and four clamping assemblies 7. The upper end of the side baffle 4 is fixedly connected to the lower end of the top plate 5. In order to ensure the conveying capacity of the guide chute, the side baffle 4 is located directly above the inclined section of the conveyor belt 13. The anti-overflow skirt 6 is movably mounted on the lower end of the side baffle 4 through the clamping assemblies 7. At the same time, the anti-overflow skirt 6 slides in contact with the inclined section of the conveyor belt 13 at the corresponding position to form a dynamic seal. See Figure 6The anti-overflow skirt 6 is an inverted Y-shaped structure composed of a main plate 61 and a secondary plate 62 of the same length. The main end face of the secondary plate 62 is perpendicular to the main end face of the main plate 61. After assembly, the main plate 61 is tightly fitted to the side baffle 4 under the pressing action of the pressing component 7. The first end of the secondary plate 62 is fixed to the end of the main plate 6 away from the side baffle 4. The secondary plate 62 divides the main plate 6 into an upper side plate and a lower side plate. The lower side plate is the part of the main plate 61 located below the secondary plate 62. The width of the lower side plate is a, and the width of the secondary plate 62 is b. The width b of the secondary plate 62 and the width a of the lower side plate satisfy b > a / tan(θ). This setting allows the lower side plate to be suspended above the conveyor belt 13 while the secondary plate 62 is in contact with the conveyor belt 13. In practical applications, the main plate 61 can block coarser materials in the guide chute, while the secondary plate 62 can block finer materials. The structure of the anti-overflow skirt 6 enables graded blocking of materials of different particle sizes, significantly improving the comprehensiveness and effectiveness of the seal.

[0021] Four clamping components 7 are fixedly mounted on the side baffle 4 and spaced apart along the length of the side baffle 4; The clamping assembly 7 includes a fastener 71, a connecting bolt 72, an angle aluminum 73, an eccentric handle 74, and a rotating shaft 75. The connecting bolt 72 is fixedly welded to the side baffle 4. The fastener 71 has a through hole that slides with the threaded rod of the connecting bolt 72, and the fastener 71 is slidably sleeved on the threaded rod of the connecting bolt 72. The angle aluminum 73 is movably mounted on the fastener 71 and close to the main plate 61. The eccentric handle 74 is rotatably mounted on the end of the connecting bolt 72 away from the side baffle 4 via the rotating shaft 75. The eccentric handle 74 is pressed against the fastener 71. Rotating the eccentric handle 74 can drive the fastener 71 to push the angle aluminum 73 closer to the main plate 61 and press it against the main plate 61, increasing the friction between the main plate 61 and the side baffle 4 to fix the position of the spill skirt 6. Through the above settings, the horizontal height of the spill skirt 6 can be easily adjusted to adapt to different working conditions or wear, improving the flexibility of use.

[0022] The fastener 71 has a C-shaped structure and is composed of a fixing block 711, a connecting block 712 and a pressing block 713 in sequence from top to bottom. The through hole is located in the middle of the connecting block 712. The pressing block 713 has a right-angle groove 714 and a sliding groove 715 that are interconnected. The right-angle groove 714 is located at the outer end of the pressing block 713, and the sliding groove 715 is an arc groove, and its opening direction is the same as the length direction of the anti-overflow skirt 6. The angle aluminum 73 consists of an angle aluminum body 751 and a connecting shaft 752 with the same length direction. The connecting shaft 752 is fixedly installed on the outer right-angle side of the angle aluminum body 751. After installation, the angle aluminum body 751 is located in the right-angle groove 714, and the connecting shaft 752 is slidably installed in the slide groove 715, allowing the angle aluminum 73 to perform limited up-and-down flipping within the slide groove 715. After rotating the eccentric handle 74, the angle aluminum body 751 abuts against the upper side plate, while the fixing block 711 abuts against the side baffle 4, forming a lever pressing effect. The length of the angle aluminum 73 is greater than the width of the fastener 71, so that when the angle aluminum 73 presses against the anti-overflow skirt 6, the force on the anti-overflow skirt 6 is more even, and under this condition, the anti-overflow skirt 6 can fully fit against the side baffle 4.

[0023] Furthermore, the upper side plate is provided with anti-slip grooves that cooperate with the angle aluminum 73 to improve the stability of the anti-overflow skirt 6 after installation.

[0024] Furthermore, the end of the sub-plate 62 away from the main plate 61 is provided with a downwardly protruding anti-slip bar to enhance the wear resistance of the end of the sub-plate 62.

[0025] In one embodiment, the sub-plate 62 may also be made of rubber, which, under pressure, changes the line contact between the sub-plate 62 and the conveyor belt 13 into a surface contact, thereby improving the sealing performance.

[0026] This technical solution achieves graded dynamic sealing of coarse and fine materials through the inverted Y-shaped anti-overflow skirt design, significantly improving the overall sealing performance. The combination of a lever-type clamping mechanism and a flip-up aluminum angle allows for quick adjustment and clamping of the anti-overflow skirt height, offering flexible operation and high stability. The spatial layout of the side baffles and the inclined section of the conveyor belt ensures sealing while maintaining the conveying capacity of the guide chute. The overall structure reduces frictional resistance and belt wear without the need for complex springs or guide rods, effectively preventing material spillage and offering strong adaptability, making it particularly suitable for high-load, multi-condition bulk material conveying environments.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
