Things about loader bucket teeth: dynamic and daily maintenance

Bucket teeth, as the terminal parts of the loader working device, shoulder the heavy responsibility of "pioneer" in shoveling operations. It is like a sharp blade in the hands of a soldier, frequently in direct contact with various materials, and bears huge impact force, friction and material cutting force. In large earthwork construction sites or hard mining environments, the wear rate of bucket teeth is amazingly fast, and it can be called the "king of consumables" of loaders.

From the appearance, the wear form of bucket teeth is mainly manifested in the gradual shortening of length and the gradual thinning of thickness. In severe cases, the upper and lower parts even "part ways". There are many reasons for the wear of bucket teeth. The first is the working environment. In stone construction, the hardness and sharp edges of the stone will accelerate the wear of the bucket teeth; the second is the material characteristics. The sticky material is easy to adhere to the bucket teeth, which will increase the additional friction; the operation mode of the loader is also very critical. Brutal operation, such as letting the bucket teeth hit the material violently, or using it in harsh working conditions for a long time, will make the bucket teeth "miserable" and accelerate its loss.

Since the wear of bucket teeth is inevitable, daily inspection and maintenance are particularly important. Before working every day, you need to spend a few minutes to visually inspect the bucket teeth. Mainly check the degree of wear of the bucket teeth. Once the wear exceeds the use limit, it will not only damage the tooth seat and bucket, but also seriously affect the excavation efficiency and reduce production. At the same time, don't forget to kick the bucket teeth with your feet to check whether they are stable. If they are loose, they must be tightened immediately, otherwise the bucket teeth will fall off during the operation, which will be a big trouble.

In addition to daily inspections, there are some maintenance tips. For example, the bucket teeth on both sides of the bucket usually wear faster than the middle ones. When the wear of the bucket teeth on both sides is significantly greater than that in the middle (the length difference is about 2-3cm), the positions of the bucket teeth in the middle and on both sides can be interchanged, which can make the bucket teeth wear more evenly and extend their overall service life. In addition, it is also critical to choose the right type of bucket teeth according to the different construction site operation objects and operation contents. In mining operations, wear-resistant and high-strength mountain-opening bucket teeth should be selected; coal mining operations are more suitable for sharp bucket teeth to better pierce the material.

Let's talk about the replacement of bucket teeth. When the tip of the bucket teeth is severely worn, the force required by the loader to cut in will increase significantly, which will lead to increased fuel consumption and reduced efficiency. At this time, it is time to replace new bucket teeth in time. When replacing, in order to maintain uniformity, try to replace all bucket teeth at the same time, and ensure that the bucket tooth bolts are firmly and reliably fixed, so as to better protect the blade.

Although the bucket teeth of the loader are small, they play a key role in engineering operations. Paying attention to the daily dynamics of the bucket teeth and doing a good job of maintenance and replacement can not only improve the working efficiency of the loader, but also reduce production costs, making our engineering construction smoother and more efficient.
