[0002] A loader bucket usually refers to the bucket used on an excavator, also known as a digging bucket. The specific working principle is that the loader driver operates the loader's control lever or button to control the hydraulic system to allow hydraulic oil to flow into the hydraulic cylinder, and the hydraulic cylinder extends outward to push the bucket open; when the loader needs to load materials, the hydraulic system will allow the hydraulic oil to flow out of the hydraulic cylinder, the hydraulic cylinder will retract, and the bucket will close to clamp the loaded materials; after loading is completed, the driver operates the control lever or button again, and the hydraulic system will allow the hydraulic oil to flow into the hydraulic cylinder, pushing the bucket to rise, unloading the loaded materials, and completing the loading work, thereby fully improving the processing efficiency of the overall process.
