[0002] The open-pit stope is a place for open-pit mining. A series of open-pit channels are excavated from the ground surface to each ore body in the open-pit mine area, and a transportation connection between the ground and the production bench is established, so as to form a transportation system between the open-pit stope and the concentrator or the ore-crushing plant, the waste dump or the industrial square, to ensure the normal progress of the stripping and mining work. The working principle of the shoveling device usually includes three steps: excavation, loading and transportation. The excavator or the loading machine excavates the ore or rock through its working device (such as a bucket, a shovel frame, etc.), then loads the excavated material into the transportation equipment (such as a mine car, a belt conveyor, etc.), and finally the transportation equipment transports the material to the designated place.

[0029] As a technical optimization solution of the present utility model, the cleaning structure 6 includes a hydraulic rod 601, the hydraulic rod 601 is installed on the fixing block 5, the extending end of the hydraulic rod 601 is fixedly connected to a connecting plate 602, the bottom end of the connecting plate 602 is fixedly connected to a cross bar 603, the end of the cross bar 603 away from the connecting plate 602 is fixedly connected to a scraping plate 605, the scraping plate 605 is slidably connected to the bucket 3, the hydraulic rod 601 and the connecting plate 602 are perpendicular to each other, and the scraping plate 605 is in an arc structure; the automatic cleaning of the bucket 3 is realized through the cleaning structure 6, thereby saving the time of manual cleaning and making the cleaning effect of the bucket 3 better.

[0030] As a technical optimization solution of the present utility model, a chute 604 is formed on the bucket 3, and the cross bar 603 is slidably connected to the chute 604; the setting of the chute 604 makes the cross bar 603 drive the scraping plate 605 to slide more smoothly.

[0031] When the utility model is in use, first place the bucket 3 on the flat ground, then operate the loading machine to make the shovel frame 1 rotate downward, and then push the shovel frame 1 forward so that the two connecting rods 206 on the shovel frame 1 are respectively located below the corresponding hooks 207. Then operate the shovel frame 1 to rotate upward so that the connecting rod 206 is inserted into the hook 207, thereby initially installing the bucket 3 on the shovel frame 1. Then push the bucket 3 towards the shovel frame 1, and the bucket 3 drives the mounting frame 203 to move towards the shovel frame 1. When the card slots on the mounting frame 203 are aligned with the corresponding sliders 202, rotate the handwheel 205, and the handwheel 205 drives the lead screw 201 to rotate. Since the threads at both ends of the lead screw 201 are opposite, the lead screw 201 drives the two sliders 202 to slide towards the corresponding mounting frame 203 by threads. Continuously rotate the lead screw 201 until the sliders 202 are engaged with the card slots on the mounting frame 203, thereby driving the mounting frame 203 to further fix the bucket 3 on the shovel frame 1, increasing the firmness and stability of the installation of the bucket 3, and the operation is simple and convenient, making the disassembly and installation work of the bucket 3 more time-saving and labor-saving; when the coal in the bucket 3 is poured into the transport vehicle, start the hydraulic rod 601, the hydraulic rod 601 extends, and the hydraulic rod 601 drives the connecting plate 602 to move in the direction away from the bucket 3. The connecting plate 602 drives the cross bar 603 to slide in the chute 604. At the same time, the cross bar 603 drives the scraper 605 to slide in the bucket 3, and the scraper 605 rubs against the inner wall of the bucket 3. Through the friction between the scraper 605 and the bucket 3, the coal slag adhering to the inner wall of the bucket 3 is peeled off from the inner wall of the bucket 3. Then drive the shovel frame 1 to move, so that the shovel frame 1 drives the bucket 3 to pour the internal coal slag outwards, thereby realizing the automatic cleaning of the bucket 3, saving the time of manual cleaning, and at the same time making the cleaning effect of the bucket 3 better.
