[0032] The elevation indicating device 3 includes a fixed rod 3.1, an indicating rod 3.1, a damper 3.4, a protective shell 3.3 and a bolt and nut combination.

[0033] The fixed rod 3.1 is welded by square tube, the first upper connecting hole 3.1.2 is arranged at the lower end of the fixed rod 3.1, the upper connecting bolt nut combination 4 can be passed through the first upper connecting hole 3.1.2, and the fixed rod 3.1 is fixed on the side wall of the bucket 1 through the second upper connecting hole 3.3.2 on the protective shell 3.3. The limiting card 3.1.1 is arranged above the first upper connecting hole 3.1.2, the limiting card 3.1.1 can be clamped on the protective shell 3.3, so that the fixed rod 3.1 is kept consistent with the direction of the protective shell 3.3.

[0034] The indicating rod 3.2 is welded by square tube, rotating bearing 3.6 and counterweight 3.8, the rotating bearing 3.6 can ensure that the indicating rod 3.2 rotates freely, the counterweight 3.8 can keep the indicating rod 3.2 in a vertical state, the damper top head 3.7 is arranged on the two side surfaces of the indicating rod 3.2 respectively, the damper top head 3.7 can cooperate with the damper 3.4 to reduce the swing of the indicating rod 3.2 and make it quickly recover to a vertical state.
