The operating art and practical skills of coal mine excavators（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. hereby provides the following content on the operating art and practical skills of coal mine excavators.

Next, let’s talk about mining efficiency. When the bucket cylinder forms a 90 degree angle with the connecting rod and the arm cylinder also forms a 90 degree angle with the arm, the excavation force reaches its maximum. To maximize excavation efficiency, the bucket teeth should be kept at an angle of approximately 30 degrees to the ground, which helps reduce soil resistance. When using a boom for excavation, it is best to maintain its angle within the range of 45 degrees in the front to 30 degrees in the back, which can more effectively utilize the mechanical force. Simultaneously using the boom and bucket for collaborative operation can further improve overall work efficiency.

When dealing with hard rocks, using a bucket directly for excavation may cause unnecessary damage to the machinery. Therefore, it is recommended to adjust the position of the machinery according to the direction of rock cracks, so that the bucket can more easily cut in. If the rock has not yet broken, blasting treatment should be carried out first, and then excavation should be carried out with a bucket. This not only protects the machinery from damage, but also improves the safety of work.

Maintaining mechanical balance is crucial when performing slope leveling operations. Place the machinery on a stable ground and pay attention to the coordination of the actions of the boom and the arm to ensure speed matching between the two. This precise manipulation is crucial for achieving the desired slope effect.

In loading operations, Haoyun Heavy Industry should minimize the turning radius of machinery as much as possible to ensure efficiency and accuracy. Choosing the left side rotary loading is usually more ideal, as it can provide better visibility and reduce unnecessary delays caused by rotation. The loading sequence is also important: load sand and gravel first, followed by larger stones, to minimize the impact on the truck.

Finally, when working in soft areas or water, it is crucial to understand the local soil conditions and limit the excavation depth of the bucket. This can not only prevent potential dangers such as landslides or collapses, but also prevent machinery from getting too deep into the soil. When working in water, special attention should be paid to the water level to ensure that it is below the centerline of the sprocket wheel, in order to prevent problems such as insufficient lubrication or water ingress into the electrical system.

In short, the operation of excavators is both a science and an art. By following these practical techniques, operators can not only improve work efficiency, but also maximize the service life of machinery while ensuring safety. Remember, every precise operation is an optimization of mechanical performance and a part of contributing to the success of the project.
