[0007] As a preferred technical scheme of the utility model, the number of back plate supports is two, and the two back plate supports are symmetrically arranged on the lower surface of the back plate.

[0008] As a preferred technical scheme of the utility model, the driving mechanism is a hydraulic telescopic rod, the telescopic end of the hydraulic telescopic rod is connected with the connecting seat, and the fixed end of the hydraulic telescopic rod is fixedly connected with the arm of the excavator.

[0009] As a preferred embodiment of this utility model, a connecting plate for connecting to the excavator arm is provided on one side of the top plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the rear-discharge combined electric shovel bucket is reasonably designed and ingeniously conceived. By connecting the various parts of the bucket with bolts, if a certain part is damaged during use, only the corresponding part needs to be replaced, without replacing the entire bucket. Disassembly is convenient and maintenance costs are reduced. At the same time, with the rear plate flip-up design, during unloading, only the rear plate needs to be opened to unload the material from the rear end, without having to lift the rear end of the bucket to unload from the front, thus improving unloading efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see Figures 1-2 This utility model provides a technical solution: a rear-discharge combined electric shovel bucket, including a bottom plate 1, side plates 2, top plate 3, rear plate 4, and bucket teeth 5. There are two side plates 2, which are symmetrically arranged between the bottom plate 1 and the top plate 3. The side plates 2 are connected to the bottom plate 1 by a second connecting bolt 7, and the side plates 2 are connected to the top plate 3 by a third connecting bolt 8. The bucket teeth 5 are connected to the bottom plate 1 by a first connecting bolt 6. A connecting plate 9 for connecting to the excavator arm is provided on one side of the top plate 3. The side plates 2 are bolted to the bottom plate 1 and the top plate 3, which facilitates replacement when damaged. The bucket teeth 5 are bolted to the bottom plate 1, which facilitates replacement of the bucket teeth 5 and reduces production and replacement costs.
