Problems solved by technology
The traditional structure is to install a layer of rubber plates on the door frame and a layer of rubber plates on the door. After the door is closed, the two layers of rubber plates are compressed to achieve sealing. The problem with this structure is that the rubber plates are easily loose after the door plate is deformed Leakage, so how to solve the sealing problem of the discharge door is a difficult problem before us

The invention discloses an ore funnel discharging door sealing structure. The sealing structure comprises a door hole formed in a carriage and a door leaf matched with the door hole; the door leaf enters through a door leaf convex part and leaves the door hole to be opened and closed, a sealing convex ring is arranged around the door hole, a door leaf sealing groove is formed in the periphery of the door leaf convex part, and a door leaf sealing glue cushion is arranged in the door leaf sealing groove; when the door leaf convex part enters the door hole, the sealing convex ring is located in the door leaf sealing groove, the sealing convex ring makes contact with the door leaf sealing glue cushion, powder ore can be effectively sealed, the defects of a traditional structure can also be overcome, after a powder ore transportation vehicle is provided with the sealing device and uses the sealing device, the powder ore leakage problem of a long-distance transportation vehicle system can be effectively solved, a discharging door is not prone to deformation in the using process, the sealing effect is improved, and meanwhile service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of locomotive carriages, in particular to a sealing structure for an ore hopper discharge door. Background technique [0002] At present, in the transportation of coarse-grained ore hopper trucks, the discharge door can be unsealed if no leakage is caused. However, in the transportation of powdered ore hopper trucks, the sealing of the discharge door has become a key issue. The traditional structure is to install a layer of rubber plates on the door frame and a layer of rubber plates on the door. After the door is closed, the two layers of rubber plates are compressed to achieve sealing. The problem with this structure is that the rubber plates are easily loose after the door plate is deformed Leakage, so how to solve the sealing problem of the discharge door is a difficult problem before us. Contents of the invention [0003] The purpose of the present invention is to solve the problems of the prior art...
