[0002] The feed chute is installed at the receiving point of the belt conveyor, which can concentrate the material falling from the hopper to the middle of the conveyor belt before reaching the belt speed, thus preventing the material from spilling out. The feed chute and the conveyor belt need to be sealed during installation, usually by a sealing device. The existing sealing device is a structure used for sealing the feed chute and the conveyor belt on the belt conveyor.

[0003] In the process of transporting bulk materials using existing belt conveyors, especially in industries such as coal and ore, the sealing devices of the guide troughs at the conveyor belt level are not thorough enough when encountering conditions such as high drop transfer, large belt vibration, and inconsistent idler height. Furthermore, they are prone to wear and continuous leakage and dust spillage during use, failing to maintain stable sealing performance. This increases auxiliary workload such as manual adjustment and cleaning, and has a certain negative impact on the environment and safe production, reducing production efficiency and affecting the sealing between the conveyor belt and the guide trough during use. Therefore, this utility model proposes a labyrinth-type guide trough sealing device. Utility Model Content

An angle steel strip 1012 is provided on the surface of the built-in dustproof sealing skirt 1011. A clamp 1013 is engaged and installed on the outer surface of the angle steel strip 1012. After the angle steel strip 1012 is closed, the clamp 1013 can be pressed against the surface of the angle steel strip 1012 to clamp and fix the built-in dustproof sealing skirt 1011.

[0026] In order to facilitate the clamping and installation of the clamp 1013 and the angle steel strip 1012 by means of the rotation reinforcement assembly, thereby clamping and reinforcing the built-in dustproof sealing skirt 1011, in this embodiment, preferably, the rotation reinforcement assembly includes a threaded rod 1016 that is limited inside the limiting mounting plate 1014.

A rotating handle 1017 is welded and fixed at the connection between the two ends of the internal threaded post 1015. The internal threaded post 1015 is rotated by the rotating handle 1017 on the outer surface of the threaded rod 1016 to clamp the clamp 1013 and the angle steel strip 1012 onto the surface of the built-in dustproof sealing skirt 1011 for reinforcement and installation.

[0027] To facilitate enhanced sealing through the external sealing assembly, in this embodiment, preferably, the external sealing assembly includes an external dustproof sealing skirt 1021 disposed at the connection between the side of the conveyor belt 102 and the side of the guide trough 101. The bottom surface of the external dustproof sealing skirt 1021 is tightly fitted to the surface of the conveyor belt 102, and the upper surface of the external dustproof sealing skirt 1021 is in close contact with the lower surface of the internal dustproof sealing skirt 1011 and extends into the interior. The external dustproof sealing skirt 1021 can be closed at the connection between the bottom end of the internal dustproof sealing skirt 1011 and the conveyor belt 102, facilitating the sealing installation of the external surface to prevent dust and leakage.

[0028] In order to facilitate the pressing and fixing of the top of the external dustproof sealing skirt 1021 by means of the pressing and mounting assembly, in this embodiment, preferably, the pressing and mounting assembly includes four mounting plates 1022 that are fixedly mounted on both sides of the guide trough 101 by bolts. Angle steel fixing bases 1023 are welded and fixed to the bottom of the four mounting plates 1022. The surface of the angle steel fixing base 1023 is in contact with the surface of the external dustproof sealing skirt 1021. A channel steel pressure strip 1024 is correspondingly closed and installed on the outer surface of the external dustproof sealing skirt 1021. The inner surface of the top of the external dustproof sealing skirt 1021 can be pressed and fixed against the surface of the angle steel fixing base 1023, and the channel steel pressure strip 1024 can be closed again.

[0029] To facilitate the re-positioning and fixing of the channel steel pressure strip 1024 using the anti-detachment reinforcement component, in this embodiment, preferably, the anti-detachment reinforcement component includes five pairs of connecting iron chains 1025 bolted to the upper surface of the angle steel fixing base 1023. The ends of two connecting iron chains 1025 are respectively bolted to anti-detachment inclined iron plates 1028 and anti-detachment pins 1029. A limiting hole plate 1026 is integrally provided on the surface of the angle steel fixing base 1023, and the limiting hole plate 1026 penetrates the interior of the external dustproof sealing skirt 1021 and the channel steel pressure strip 1024. The channel steel strip 1024 can be closed on the top outer side of the external dustproof sealing skirt 1021. The limiting hole plate 1026 passes through the interior of the external dustproof sealing skirt 1021 and the channel steel strip 1024 for easy locking and installation. The anti-detachment inclined iron plate 1028 passes through the interior of the limiting hole plate 1026. The surface of the anti-detachment inclined iron plate 1028 is provided with locking holes 1027 at equal intervals to engage with the anti-detachment pin 1029. The anti-detachment inclined iron plate 1028 is locked into the interior of the limiting hole plate 1026 again, and the anti-detachment pin 1029 is locked into the interior of the locking hole 1027 for anti-detachment reinforcement installation.

[0030] The working principle and usage process of this utility model are as follows: When using this labyrinth-type material guide trough sealing device, the first step is to install it. The built-in dustproof sealing skirt 1011 can be closed on the side of the material guide trough 101, so that the gap between the bottom end of the built-in dustproof sealing skirt 1011 and the surface of the conveyor belt 102 is the same as the thickness of the external dustproof sealing skirt 1021. At this time, the angle steel pressure strip 1012 is closed on the surface of the built-in dustproof sealing skirt 1011. The clamp 1013 passes through the threaded rod 1016. The hand-held rotating handle 1017 drives the internal threaded column 1015 to press against the clamp 1013 on the outer surface of the threaded rod 1016. When the clamp 1013 presses, the bottom end of the clamp 1013 is pressed tightly against the surface of the angle steel pressure strip 1012 to reinforce the installation of the built-in dustproof sealing skirt 1011, thereby facilitating the installation and use of the built-in dustproof sealing skirt 1011.

[0031] Then, after fixing the angle steel fixing base 1023 by installing the fixing plate 1022, the external dustproof sealing skirt 1021 is closed on the side. The bottom end of the external dustproof sealing skirt 1021 extends into the interior and presses tightly against the surfaces of the internal dustproof sealing skirt 1011 and the conveyor belt 102. The top end of the external dustproof sealing skirt 1021 contacts the angle steel fixing base 1023. The channel steel pressure strip 1024 is closed again on the surface of the external dustproof sealing skirt 1021. The limiting hole plate 1026 passes through the interior of the external dustproof sealing skirt 1021 and the channel steel pressure strip 1024. The anti-detachment inclined iron plate 1028 is inserted into the interior of the limiting hole plate 1026 by connecting the iron chain 1025. The anti-detachment pin 1029 is engaged in the interior of the corresponding locking hole 1027, so that the anti-detachment inclined iron plate 1028... The design is not easily movable, making it convenient to fix the external dustproof sealing skirt 1021 to the bottom end of the guide trough 101 and the bottom end of the conveyor belt 102, and seal the outer surface. This allows the internal dustproof sealing skirt 1011 and the external dustproof sealing skirt 1021 to form a labyrinth-like sealing structure between the guide trough 101 and the conveyor belt 102, strengthening the sealing installation and achieving dustproof and leak-proof functions. This ensures that the guide trough 101 is sealed and does not leak, reducing workload and cost, while improving production efficiency. It also improves the sealing effect between the conveyor belt 102 and the guide trough 101 during use, preventing dust and leaks. During use, the internal dustproof sealing skirt 1011 and the external dustproof sealing skirt 1021 need to be manually adjusted approximately every six months. When replacing them, simply reverse the operation.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
