When excavator drivers operate excavators and buckets, improper operation may increase the workload and cause unnecessary harm to the excavator bucket. So what are the skills and precautions for operating excavator buckets? Now let's take everyone to explore.
1. Operational techniques
First, confirm the surrounding conditions. When rotating, it is necessary to have a clear understanding of the surrounding obstacles and terrain and operate safely; During operation, it is necessary to confirm the front and rear directions of the track to avoid tipping or impact; Try not to face the final drive towards the excavation direction, otherwise it may damage the walking motor or hose; During operation, it is necessary to ensure that the left and right tracks are in complete contact with the ground to improve the dynamic stability of the entire machine.
2. Effective mining methods
When the digging cylinder and connecting rod, as well as the stick cylinder and the stick are at a 90 degree angle to each other, the digging force is maximum; When the digging bucket teeth maintain a 30 degree angle with the ground, the excavation force is the best, which means the cutting resistance is the smallest; When excavating with a stick, ensure that the angle range of the stick is between 45 degrees from the front to 30 degrees from the back. Using both the boom and the excavator can improve excavation efficiency.
3. Excavation of Rock
Using a excavator to excavate rocks can cause significant damage to the machine and should be avoided as much as possible; When excavation is necessary, the position of the body should be adjusted according to the direction of the rock crack, so that the excavator can smoothly enter and excavate; Insert the bucket teeth into the rock cracks and excavate with the digging force of the bucket rod and bucket (pay attention to the slipping of the bucket teeth); Rock that has not been broken should be broken first and then excavated using a excavator.
4. Noteworthy operation
The hydraulic cylinder is equipped with a buffer device inside, which can gradually release back pressure near the end of the stroke; If the piston is subjected to an impact load after reaching the end of the stroke, it will directly touch the cylinder head or bottom, which is prone to accidents. Therefore, it is advisable to leave as much clearance as possible when reaching the end of the stroke.
The use of rotary motion for soil pushing operation will cause abnormal stress on the excavation bucket and working device, causing distortion or weld cracking, and even pin breakage. This operation should be avoided as much as possible.
Using the weight of the body to excavate can cause abnormal stress on the slewing bearing, as well as strong vibration and impact on the chassis. Therefore, the application of hydraulic cylinders or hydraulic pipelines can cause significant damage.
When loading and unloading heavy materials such as rocks, the material should be unloaded near the bottom of the truck carriage, or the soil should be loaded first and then the rocks. It is prohibited to unload at high altitudes to reduce impact damage to the truck.
When the track is deeply immersed in the mud, place a wooden board under the bucket, use the bottom of the bucket to support the track, and then place a wooden board under the track to drive the machine out.
5. Slope leveling operation
When carrying out surface trimming, the machine should be placed flat on the ground to prevent the body from shaking. It is crucial to grasp the coordination of the movements of the boom and bucket, and control the speed of both is crucial for surface trimming.
6. Working in soft areas or in water
When working in soft soil areas, it is necessary to understand the degree of soil compaction and pay attention to limiting the excavation range of the excavator to prevent accidents such as landslides and collapses, as well as deeper vehicle subsidence.
When working in water, attention should be paid to the allowable water depth range of the vehicle body (the water surface should be below the center of the carrier roller); If the horizontal plane is high, the inside of the slewing bearing
