Daily maintenance tips for loader bucket blade
The blade (also called shovel edge or cutting edge) of the loader bucket is a key component that directly contacts the material, and its condition directly affects the operating efficiency and equipment life. Daily maintenance can not only extend the service life of the bucket, but also reduce fuel consumption and maintenance costs. This article will introduce in detail the daily inspection, maintenance and replacement tips of the loader bucket blade to help you improve the operating efficiency of the equipment.
The main function of the bucket blade is to cut into the material and reduce bucket wear. It is usually made of high-strength wear-resistant steel. Common types of wear include: long-term friction with materials such as sand, gravel, and soil causes the blade to become thinner or blunt. The bucket hits hard objects (such as rocks and concrete blocks) and causes the blade edge to break. Overload operation or improper operation causes the blade to deform under force. The bolts that fix the blade loosen due to vibration, affecting the safety of the operation.
The consequences of ignoring blade maintenance: the bucket body wears more and the replacement cost is higher. The operating resistance increases, which increases fuel consumption. The operational stability decreases, affecting safety.
How to judge whether the blade needs maintenance? First, you can visually inspect it. If the wear exceeds 30%-50% of the original thickness (different manufacturers have different standards), you should consider replacing it. A blunt blade will increase the resistance to cutting and reduce the efficiency of the operation. If cracks are found, they should be replaced in time to avoid cracking during operation. Check whether the fixing bolts are loose, missing or broken.
Secondly, you can observe the operating status. If the machine needs more power to cut into the material, it may be that the blade is severely worn. After the blade is worn, the sealing of the bucket decreases, and the material is easy to leak out of the gap. Loose or deformed blades may cause the vibration of the bucket to increase during operation.
Daily maintenance first requires regular cleaning of the bucket, and clean up the adhered soil and gravel after operation to prevent corrosion and additional wear. Check whether there is hard material on the back of the blade to avoid deformation caused by long-term compression. Then check and tighten the bolts, and use a torque wrench to tighten the bolts according to the torque value specified by the manufacturer (usually 300-500 N·m). It is recommended to check once before operation every day to prevent loosening and falling off. Some bucket blades are designed to be reversible on both sides. When one side is worn, it can be removed and reversibly installed to extend the service life. Apply anti-rust grease regularly to prevent the bolts from rusting and being difficult to disassemble. Check the wear of the pin shaft to avoid blade shaking due to excessive clearance. Finally, some improper operations should be avoided. For example, it is forbidden to hit hard objects (such as rocks and frozen soil) with the bucket to prevent the blade from cracking. Avoid overloading. Excessive load will accelerate the wear of the blade and bucket. Maintain a stable shovel to reduce the impact of impact load on the blade.
Therefore, it is generally recommended to replace the blade when it is worn to 50% of the original thickness. If large-scale cracking, deformation or cracks occur, it should be replaced immediately.
Finally, be sure to develop a good maintenance habit. Check the blade wear and bolt status before operation. Prevent material accumulation from accelerating corrosion. Avoid impact load and overload use. Replace immediately after reaching the wear limit to avoid damage to the bucket body.
Through scientific daily maintenance, the service life of the bucket blade can be extended by 30%-50%, while improving the overall operating efficiency of the loader.
