Demystifying bucket teeth design: the trade-off between excavation efficiency and durability

Reasonable bucket tooth design can be called the "secret weapon" to improve work efficiency. It covers many key aspects, and each detail plays a decisive role in the actual performance of the bucket teeth.

1. Blade shape: the game between efficiency and durability
The blade shape of the bucket tooth directly affects the excavation efficiency and durability. When excavating soft materials such as ordinary soil and soft clay, sharp and thin blades have significant advantages. It can cut in easily like a dagger, greatly reducing the excavation resistance and making the excavation action fast and efficient. For example, in the foundation excavation of urban construction sites, excavators equipped with such blade bucket teeth can quickly dig up and load soft backfill soil, shortening the construction period. However, in the face of hard rocks, frozen soil blocks, etc., thin blades are not thick enough, and frequent contact is easy to wear or even crack, and the durability is poor.

Wide and thick blades are suitable for excavating hard materials. In mining scenarios, the rock is hard, and the wide and thick blade can effectively disperse the huge pressure from the hard rock with its thick structure. Even if it is rubbed and collided for a long time, it can maintain good integrity, and the wear rate is much lower than that of the thin blade, and the wear resistance is excellent.

2. Connection method: selection of adaptation needs
The connection method between bucket teeth and bucket is related to the convenience of equipment maintenance and operation stability. Common ones include bolt connection and pin connection.

Bolt connection is easy to disassemble. Bucket teeth are frequently replaced as wearing parts. Maintenance personnel can quickly unscrew the bolts with simple tools to complete the replacement, saving maintenance time and labor costs. It is suitable for scenes with stable working environment and frequent replacement of bucket teeth, such as small excavators for urban road construction. However, during high-intensity impact operations, bolts are easy to loosen, affecting the stability of the connection.

Pin connection is strong and can withstand greater impact force. In high-intensity working environments such as large-scale mining and water conservancy projects, it can ensure that the bucket teeth are still closely connected to the bucket under extreme stress. However, its disassembly is relatively complicated, requiring professional tools and operating skills, which increases the difficulty of maintenance. Therefore, it is necessary to choose according to the actual working intensity and maintenance needs. If the working intensity is high and the connection is stable, choose pin connection; if you pay attention to the convenience of daily maintenance, choose bolt connection.
