Description

Technical Field

[0001] The utility model relates to the technical field of belt dustproof sealing, in particular to a reciprocating belt dustproof sealing structure. Background Art

[0002] The main purpose of the reciprocating belt dustproof sealing structure is to effectively reduce the diffusion of dust during operation, reduce the degree of pollution in the working environment, and protect the health of operators. The reciprocating belt dustproof sealing structure is usually made of wear-resistant and corrosion-resistant materials and can adapt to various harsh working environments, such as high temperature, high humidity, dust, etc., to ensure the normal operation of the equipment.

[0003] According to a belt conveyor sealing and dustproof device disclosed on the patent website (authorization announcement CN 219636455U), "a belt conveyor sealing and dustproof device comprises a belt conveyor, a first dust cover and a second dust cover, a fixing plate is fixedly provided on the side of the belt conveyor, a connecting groove is provided on the fixing plate, and the first dust cover and the second dust cover can be movably inserted in the connecting groove."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the device inserts the first dust cover into the connecting groove and fixes it by a screw, and then pulls the movable rod to drive the movable plate and the connecting plate to move, so that after the movable plate is disengaged from the interior of the hollow plate, the rectangular plate on the second dust cover on the other side is inserted into the interior of the hollow plate, thereby completing the fixation of the first dust cover and the second dust cover. However, during actual use, the device requires pulling the movable rods on both sides with one hand at the same time, so that the connecting plate is disengaged from the hollow plate, so that the rectangular plate on the second dust cover on the other side can be inserted into the interior of the hollow plate, and the staff on both sides need to complete the operation synchronously to complete the fixation of the first dust cover and the second dust cover, which is inconvenient for the staff to quickly complete the fixation of the first dust cover and the second dust cover. Moreover, when the dust cover is not installed in the connecting groove, and the connecting groove is exposed to the outside, it is easy for debris to enter the interior of the connecting groove during the non-installation period, which is inconvenient for the later connection of the dust cover and the connecting groove. Therefore, it is necessary to improve a reciprocating belt dustproof sealing structure. Utility Model Content
