[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] like Figure 1 , Figure 2 As shown, Figure 1 What is shown is the front view schematic diagram of the bucket structure in the embodiment, Figure 2 What is shown is the cross-sectional schematic diagram of the bucket structure in the embodiment;

[0021] The device includes:

[0022] The bucket body 10 includes an inner cavity 11 and a discharge port 12 opened on the side wall to connect the inner cavity 11 with the outside. A discharge door 20 is rotatably provided on the outer wall of the bucket body 10 at a position corresponding to the discharge port 12. The discharge door 20 opens or closes the discharge port 12. The side wall of the bucket body 10 where the discharge port 12 is opened is also provided with a mounting groove 13 connected with the discharge port 12.

[0023] The protective plate 30 is movably disposed in the mounting groove 13 along the vertical direction. The protective plate 30 can open or close the discharge port 12. The protective plate 30 and the discharge door 20 provide double protection to prevent the material in the inner cavity 11 from leaking during transportation.

[0024] The discharge port 12 can also be closed or opened by the movable protective plate 30. The protective plate 30 cooperates with the discharge door 20 to play a double-layer closing and protective role in the process of transporting materials, avoiding the formation of gaps at the discharge port 12 under the action of the squeezing force of the material, thereby reducing the possibility of leakage.

[0025] Specifically, before adding materials into the inner cavity 11, the protective plate 30 is first moved downward in the mounting groove 13 to close the discharge port 12, and then the discharge door 20 is closed. At this time, the subsequently loaded materials will be first blocked by the protective plate 30, and then blocked by the discharge door 20. The two cooperate to play a protective role to prevent material leakage, and also to prevent the discharge door 20 from being opened by mistake or the discharge door 20 from being damaged and causing material leakage.

[0026] The diagonal length of the discharge door 20 is greater than the diagonal length of the discharge port 12 , so that the discharge port 12 can be closed.

[0027] The side wall of the bucket body 10 provided with the mounting groove 13 is also provided with a driving structure, the driving structure is connected to the protection plate 30, and the driving structure drives the protection plate 30 to move in the vertical direction;

[0028] The driving structure includes a driving member 31 . The output end of the driving member 31 faces downward and is connected to a connecting rod 32 . The connecting rod 32 is L-shaped, and the end thereof is connected to the bottom end of the protective plate 30 .

[0029] The driving member 31 may be an electric push rod, and its output end drives the protection plate 30 to move up and down along the installation groove 13 through the connecting rod 32, thereby changing the position of the protection plate 30 to switch the state of opening or closing the discharge port 12.

[0030] The discharge door 20 is hingedly arranged on the bucket body 10 and is located below the discharge port 12. A spring buckle 21 is also arranged at the end of the discharge door 20 away from the hinged end. A fixed hook 22 is also arranged on the outside of the side wall of the bucket body 10 where the discharge port 12 is opened. When the discharge door 20 closes the discharge port 12, the spring buckle 21 is movably engaged with the fixed hook 22.

[0031] The opening and closing states of the discharge door 20 are switched by means of the spring buckle 21 and the fixed hook 22 . The spring buckle 21 is movably engaged with the fixed hook 22 , and locking and opening are achieved by elastic deformation of the spring buckle 21 .

[0032] A pad 41 is also provided at the bottom of the inner cavity 11 of the bucket body 10. The pad 41 is tilted and one end close to the discharge port 12 is lower than the other end. A buffer 42 is also provided between the bottom end of the pad 41 and the inner bottom wall of the bucket body 10.

[0033] The pad 41 and the buffer 42 play an anti-impact role when materials are added, thereby preventing the bottom of the bucket body 10 from being damaged by the impact of ore and the like for a long time, thereby increasing the service life of the bucket body 10; the buffer 42 can be a pad made of flexible materials such as rubber pads; in addition, the tilted pad 41 can facilitate unloading.

[0034] Working principle: When the device is in use, before adding materials into the inner cavity 11 of the bucket body 10, first open the driving member 31, so that the driving member 31 drives the protective plate 30 to move downward in the installation groove 13 until the discharge port 12 is closed, and then the discharge door 20 is rotated to a position to block the discharge port 12, and the spring buckle 21 is clamped on the fixed hook 22. At this time, the subsequent loaded materials will first be blocked by the protective plate 30, and then blocked by the discharge door 20. The two cooperate to play a protective role to prevent material leakage, and also to prevent the discharge door 20 from being opened by mistake or the discharge door 20 from being damaged and causing material leakage.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
