A window 11 is opened on the side door main body 1. A first sliding plate 12 and a second sliding plate 13 are slidably connected inside the window 11. The first sliding plate 12 and the second sliding plate 13 are made of glass. At the middle of one end of the first sliding plate 12 and the second sliding plate 13 close to the inner wall of the window 11, a protruding handle 14 is provided. The function of the protruding handle 14 is to make it more labor-saving when opening and closing the first sliding plate 12 and the second sliding plate 13. It further includes: a protective frame 2, installed on the side door main body 1 outside the excavator. A plurality of sub-grids 21 are opened on the protective frame 2. The sub-grids 21 are evenly distributed with loads through a plurality of small units, reducing local overload and improving the overall load-bearing capacity of the structure. It also enhances the rigidity of the structure, reduces deformation and sway, and makes the structure more stable. Finally, it also helps to disperse the stress concentration in the structure and reduces the risk of damage at local stress points. Anti-collision nets 22 for blocking stone fragments are provided inside the sub-grids 21. The function of the anti-collision nets 22 is to filter large flying gravel blocks; an installation opening 3 opened on the protective frame 2, and a first protection mechanism linked to the first sliding plate 12 and the second sliding plate 13 is provided inside the installation opening 3; a second protection mechanism, provided on the side door main body 1 inside the excavator for blocking the broken first sliding plate 12 and the second sliding plate 13 from splashing onto the operator.

[0028] Further, the first protection mechanism includes a sliding grille plate 31 and a fixed grille plate 32. An outer wall of one end of the sliding grille plate 31 close to the fixed grille plate 32 is fixedly connected with a convex block 33. A plurality of sub-grilles 21 are provided inside both the sliding grille plate 31 and the fixed grille plate 32. Anti-collision filter meshes 36 for filtering dust are provided inside the sub-grilles 21. The aperture of the anti-collision filter mesh 36 is smaller than that of the anti-collision mesh 22, and can filter large gravel blocks. Moreover, polyester fibers for filtering dust are provided in each hole of the anti-collision filter mesh 36. A limit stop bar 34 for restricting the sliding of the sliding grille plate 31 and the fixed grille plate 32 is provided inside the installation opening 3. The function of the limit stop bar 34 is to enable the sliding grille plate 31 and the fixed grille plate 32 to slide according to a specified position. The sliding grille plate 31 is slidably connected to the inside of the installation opening 3. One end of the sliding grille plate 31 far from the fixed grille plate 32 is fixedly connected with a connecting plate 35, and the connecting plate 35 is fixedly connected with the first sliding plate 12. The fixed grille plate 32 is fixedly connected to the inner wall of the installation opening 3.

[0029] Furthermore, the second protection mechanism includes multiple pairs of upper and lower corresponding support seats 4. A support rod 41 is fixedly connected to the middle of each pair of support seats 4. A plurality of sliding connection rings 42 arranged linearly are slidably hung on the support rods 41. A buffer curtain 43 fixedly connected with the multiple sliding connection rings 42 and used for blocking the first sliding plate 12 and the second sliding plate 13 is provided in the middle of a pair of support rods 41. The buffer curtain 43 can further prevent gravel and glass fragments from entering the operation area and protect the operator from being injured. Among them, the buffer curtain 43 effectively captures fragments, reduces the cleaning workload, and keeps the interior environment of the vehicle clean. Secondly, the buffer curtain 43 can also protect other components inside the side door from being damaged by fragments, improving the durability and reliability of the equipment. The buffer curtain 43 is made of a composite material of polyester and nylon.

[0030] In this embodiment, when using the anti-collision side door of the excavator, such as Figure 1As shown, when it is necessary to open the first sliding plate 12, it only needs to slide along the window 11 in the direction of the second sliding plate 13, so that the excavator operator can view the fixed grille plate 32 through the window 11 in the cab. And through the anti-collision filter net 36 in the multiple sub-grilles 21 on the fixed grille plate 32, the air outside the main body 1 of the excavator side door can enter the cab of the excavator only after being filtered. When it is necessary to open the second sliding plate 13, it only needs to slide along the window 11 in the direction of the first sliding plate 12, and the second sliding plate 13 drives the sliding grille plate 31 to move through the connecting plate 35, so that the operator can take and place items from outside the excavator through the window 11 and the installation opening 3. When the flying stone fragments hit the first sliding plate 12 and the second sliding plate 13 through the anti-collision filter net 36, the first sliding plate 12 and the second sliding plate 13 are impacted and crushed, and the crushed debris will also be blocked by the buffer curtain 43. And the material of the buffer curtain 43 has strong tear resistance, so that the buffer curtain 43 has toughness, and then blocks the debris and prevents the crushed debris from splashing onto the excavator operator, reducing the safety risk.
