Generally, the working range of excavators in the above working conditions is relatively open, and there are generally no obstacles within their walking and slewing ranges. Therefore, the body structure of excavators generally does not have a protection mechanism. Only a small number of excavators are equipped with guardrails on the top and front of the cab for protection. Reference can be made to a conveniently adjustable mobile multi-functional excavator cab protection device with the publication number CN114855918A.

[0003] The fields where excavators are applied are not only in open environments. Forestry is also one of the application fields. The front end of a forestry excavator is equipped with a logging machine for logging operations in the forest, and a grapple is equipped to transfer the felled wood or perform earthwork operations, etc. When operating in forest conditions, there are many shrubs, branches, etc. During the walking and slewing of the excavator, it will rub against the trees, which will damage the body of the excavator. Other parts such as the rear engine hood of the body and the power device on one side of the cab cannot be protected. Only by protecting the cab, the protection effect of the excavator body in forest operation conditions is poor, affecting the service life of the whole machine. Content of the Utility Model

[0034] An excavator vehicle body protection structure, referring to Figure 1 and Figure 2, including a vehicle body 1 consisting of a hood 11, a cab 12 and a power unit 13, anti-collision beams 2 are symmetrically arranged on both sides of the vehicle body 1, the rear side of the hood 11 is movably connected to the hood protection grille 4 through a pin shaft 32, and the left rear protection grille 6 and the right rear protection grille 5 are installed on both sides of the hood 11 and on the anti-collision beam 2 through a threaded seat, and the front protection grille 8 is installed on one side of the power unit 13 and on the anti-collision beam 2 through a threaded seat, and a cab protection grille 7 is arranged along the upper surface of the cab 12 through a channel steel 71.

[0035] Reference Figure 3 The left rear protection grille 6 includes a door beam 61, an inspection door 62 is hinged inside the door beam 61, and the inspection door 62 is fixed to the door beam 61 by a spring lock 63. A mounting beam 3 is provided on the door beam 61, and a protection lock 31 for fixing the hood protection grille 4 is provided on the mounting beam 3. The protection lock 31 fixes the hood protection grille 4 to the door beam 61.

[0036] Reference Figure 4 The right rear protective grille 5 includes an L-shaped beam 51, and an inspection door 62 is hinged inside the L-shaped beam 51. The inspection door 62 is fixed to the L-shaped beam 51 by a spring lock 63. Since the right rear protective grille 5 does not need to be installed with a protective lock 31, in order to reduce weight, an L-shaped beam 51 is used, and a spring lock 63 is horizontally arranged at the top of the L-shaped beam 51. After the spring lock 63 is pulled, the inspection door 62 is locked. A door beam ring 611 is arranged on the door beam 61, and an inspection door ring 621 is arranged on the inspection door 62. After the inspection door ring 621 passes through the door beam ring 611, the pin 631 of the spring lock 63 is pulled upward, and then the inspection door 62 is unlocked. When locking, the pin 631 is aligned with the inspection door ring 621 and the door beam ring 611. Under the action of the spring 632, the pin 631 passes through the inspection door ring 621 and the door beam ring 611 to complete the locking.

[0037] The front protective grille 8 is connected to the power unit 13 through a horizontal mounting rod 81 and an inclined mounting rod 82. Since the length of the power unit 13 is shorter than the length of the cab 12, in order to reduce the waste of installation space, the front protective grille 8 is installed on the power unit 13 at the same time through the inclined mounting rod 82 and the horizontal mounting rod 81.

[0038] The hood protection grid 4 includes a first square grid frame, the first square grid frame is bent toward the hood 11, and a plurality of steel pipes 9 are vertically staggered in the first square grid frame. Except for the left and right welded anti-collision beams 2, all other protections are steel pipe 9 welded structures, which have the advantages of light weight and good protection effect.

[0039] The front protective grille 8 includes a trapezoidal grille frame 83, in which a plurality of steel pipes 9 are arranged in parallel. The trapezoidal grille frame 83 matches the shape of the power device 13. The parallel steel pipes 9 are welded to the trapezoidal grille frame 83 to improve the strength of the trapezoidal grille frame.

[0040] Reference Figure 5 , the cab protection grille 7 includes a second square grille frame 72 which bends towards the hood 11. The protection of the cab 12 is integrated, and can wrap all the front, upper and rear parts of the cab 12. A number of steel pipes 9 are arranged in parallel in the second square grille frame 72. The second square grille frame 72 is fixed to the threaded seat at the top of the cab 12 through a number of channel steels 71.

[0041] The front protection grille 8, the cab protection grille 7 and the hood protection grille 4 all adopt an integrated structure. The anti-collision beam 2 arranged on one side has a length covering the hood 11 and the cab 12, and the anti-collision beam 2 arranged on the other side covers the hood 11 and the power device 13. The anti-collision beam 2 is welded to one side of the hood 11 and the cab 12 at the same time, and the anti-collision beam 2 on the other side is welded to one side of the hood 11 and the power device 13 at the same time. The cross-section of the anti-collision beam 2 is triangular, and the anti-collision beam 2 is hollow. On the premise of ensuring the support strength, the hollow setting can reduce the overall weight.

[0042] The installation method of the present utility model is as follows:

[0043] The left and right anti-collision beams 2 are directly welded to the left and right platforms of the excavator; threaded holes are opened on the left and right anti-collision beams 2. The lower parts of the right front protection, the right rear protection and the left rear protection are fixed to the left and right anti-collision beams 2 by bolts, and the upper parts are fixed to the threaded seats on the covering parts by bolts. There are threaded seats installed on the top of the cab 12. After drilling threaded holes in the channel steels 71, the cab protection grille 7 is fixed and installed on the threaded seats by bolts.

[0044] When it is necessary to open the hood protection grille 4 for maintenance of the hood 11, pull out the protection lock 31 outwards, then flip the hood protection grille 4 along the pin shaft 32, and then pull the spring locks 63 on both sides of the hood 11 respectively to open the left rear protection grille 6 and the right rear protection grille 5. At this time, the grilles on the rear side and both sides of the hood 11 are completely unlocked, and the maintenance of the hood 11 can be carried out.

[0045] Although the specific implementation manners of the present utility model are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present utility model. Those skilled in the art should understand that based on the technical solutions of the present utility model, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present utility model.
