In real life, when people are carrying out road construction or building construction, they often need to use mechanical equipment such as hook machine. So, as a driver, how should he operate the dynamic compaction machine? What should we pay attention to during the operation? For this series of problems, you may as well patiently look at the following introduction:

一、，我们来了解一下强夯机的有用挖掘方法：当铲斗缸和连杆、斗杆缸和斗杆之间互成90度时，挖掘力大；铲斗斗齿和地面保持30度角时，挖掘力佳，即切土阻力小。用斗杆挖掘时，应保证斗杆角度范围在从前面45度角到后面30度之间，同时使用动臂和铲斗，能提高挖掘效率。

1、 First of all, let's understand the useful excavation methods of dynamic compaction machine: when the bucket cylinder and connecting rod, and the bucket rod cylinder and the bucket rod form 90 degrees with each other, the excavation force is maximum; When the bucket teeth keep a 30 degree angle with the ground, the digging force is the best, that is, the cutting resistance is the least. When digging with the stick, the angle range of the stick should be between 45 degrees from the front to 30 degrees from the back. Using the boom and bucket at the same time can improve the digging efficiency.

二、其次，我们来了解了解操作强夯机需要注意的一些重要事项：在操作强夯机的时候，要确认周围状况，回转作业时，对周围障碍物、地形要做到心中有数，安 全操作；作业时，要确认履带的前后方向，避免造成倾翻或撞击；操作过程中，尽量不要把终传动面对挖掘方向，否则容易损伤行走马达或软管；作业时，要保证左右履带与地面完全接触，提高整机的动态稳定性。

2、 Secondly, we need to understand some important matters needing attention in the operation of the dynamic compaction machine: when operating the dynamic compaction machine, first of all, we need to confirm the surrounding conditions. When rotating, we need to know the surrounding obstacles and terrain well and operate safely; During operation, confirm the front and rear direction of the track to avoid tipping or impact; During the operation, try not to face the final drive to the excavation direction, otherwise it is easy to damage the walking motor or hose; During operation, the left and right crawlers should be fully contacted with the ground to improve the dynamic stability of the whole machine.

综上所述，我们可以看出，强夯机并不好操作。所以，这需要由驾驶员去操作，毕竟这是一项技术活。

To sum up, we can see that the dynamic compaction machine is not easy to operate. Therefore, it needs to be operated by the driver. After all, it is a technical activity.
