[0002] With the increasing attention paid to the safety protection of mechanical equipment, mechanical shields, as important devices for protecting the safety of mechanical equipment and operators, have a direct impact on production safety and personnel safety in terms of performance and quality. In the prior art, a patent document with announcement number CN219210726U discloses a split distributor for an underground dry sorting machine and a dry sorting machine. The distributor includes a conveying device and at least two shield units which are detachably connected end to end and are arranged above the conveying device. The conveying device and the shield units are arranged to form a channel for material transmission; the shield unit includes a frame and a panel detachably connected to the frame. The split distributor of the underground dry sorting machine in this application has the following advantages: 1. It is made of multiple shield units, which is easy to transport and assemble as a whole and reduces maintenance costs; 2. The frame provides support for the panel to avoid deformation of the panel and improve the structural strength and service life of the shield; 3. The frame and the panel are detachably connected, and the panel can be replaced individually without replacing the entire panel, which greatly reduces costs; 4. The frame and the panel can be sold independently as spare parts, which is easy for after-sales maintenance and modification.

[0003] Since the guard units are arranged in sequence and fixedly installed, they need to be disassembled during the maintenance process, and require the assistance of lifting equipment. Moreover, the guard units also take up a lot of space when placed on the ground after being removed, which brings many inconveniences to maintenance. Based on this, the existing dry sorting machine protective guard structure has the problem of inconvenient disassembly and assembly, which needs further improvement. Utility Model Content
