Description
Technical Field
[0001] The utility model relates to the technical field of a protection device for a WK-20M3 electric shovel bucket lip, in particular to a special-shaped protection sleeve for an electric shovel bucket tooth edge. Background Art
[0002] At present, the WK-20M3 electric shovel is one of the main mining equipment in the Barun Mining site. Barun Mining currently has two WK-20M3 electric shovels. The forearms on both sides of the bucket forearm have cracks due to wear, and the bucket lip is often broken off due to force, resulting in the scrapping of the bucket, which greatly increases the investment in production costs, reduces the operating efficiency of the equipment, and significantly increases the labor intensity of maintenance workers. Therefore, whether it can operate normally and exert efficiency will directly affect the completion of production and operation goals. This requires the electric shovel driver to inspect and replace the wear and tear, which adds cumbersome operating procedures and increases labor intensity. In order to improve operating efficiency and reduce labor intensity, we have made technical improvements to change the current wear status of the electric shovel bucket lip. At the same time, the wear-resistant shovel teeth used in the WK series electric shovels of Barun Branch are combined bucket teeth and bucket lip covers. There are many fixed accessories for the installation of the combined bucket teeth and bucket lip covers. When the electric shovel is excavating, the impact of the materials can easily cause the fixed accessories of the fixed bucket teeth and bucket lip covers to fall off, mix with the ore and rock, and then enter the crushing of the concentrator, causing damage to the crusher and affecting the normal progress of a process.
