长臂挖掘机

省时 省力 省财富

加长臂挖掘机的应用范围十分广泛，通过换装不同的附属装置，如液压锤、液压剪、推土铲、扒斗等可以完成破碎、拆卸、抓取等多种作业。那您知道如何充分发挥挖掘机很大的挖掘力吗？

The application scope of the extended boom excavator is very wide, and various operations such as crushing, disassembling and grasping can be completed by replacing different accessory devices, such as hydraulic hammer, hydraulic shear, bulldozer, scraper, etc. Do you know how to give full play to the great digging force of the excavator?

铲斗应该装满装载物

The bucket should be full of load

开始时,借助铲斗的力量进行挖掘,然后使斗齿对着挖掘方向，控制操作杆实用满行程较浅地挖掘,便可干净利落地装满铲斗。挖掘结束时,迅速从斗杆回收的动作转换为斗杆外伸。此时,聚集在铲斗斗齿处的沙土会落在铲斗的内侧,从而起到平整沙士的效果,这样,通过“抖动操作”可以防止沙土落出。

At the beginning, excavate with the help of the force of the bucket, and then make the bucket teeth face the excavation direction, and control the operating lever to excavate with a shallow full stroke, so that the bucket can be filled cleanly. At the end of digging, the action of quickly recovering from the stick is converted to stick extension. At this time, the sand accumulated at the bucket teeth will fall on the inner side of the bucket, so as to smooth the sand. In this way, the "shaking operation" can prevent the sand from falling out.

根据土质的状况选择挖掘角度

Select the excavation angle according to the soil quality

根据土质的软硬程度，选择铲斗的挖掘角度。对于软土,要增大挖掘角度,进行深度挖掘,并在短距离内结束挖掘。对于硬土，要减小挖掘角度,以降低挖掘阻力。但对于斗齿很难咬入的硬土,如果增大挖掘角度,可以使挖掘变得很容易。

Select the digging angle of the bucket according to the hardness of the soil. For soft soil, increase the excavation angle, conduct deep excavation, and end the excavation within a short distance. For hard soil, reduce the excavation angle to reduce the excavation resistance. However, for hard soil that is difficult for bucket teeth to bite into, if the excavation angle is increased, the excavation can be very easy.

有效地利用挖掘力

Use the digging force effectively

一般来说，以斗杆垂直于地面为基准，再向前50°和向内15°之间的65°范围内挖掘可使铲斗达到满铲，是有效的方法。需要进行强力挖掘的姿势挖掘力主要是利用斗杆的牵引力及铲斗的挖掘力。大挖掘力是在斗杆销轴与斗杆油缸呈90°时得以发挥的。

Generally speaking, it is an effective method to excavate within 65 ° between 50 ° forward and 15 ° inward with the stick perpendicular to the ground. The posture excavation force that requires strong excavation is mainly the traction force of the stick and the excavation force of the bucket. The large digging force is exerted when the stick pin is 90 ° to the stick cylinder.

此外挖掘机驾驶员应具有熟练的操作技术，并尽量采用复合操作，以缩短挖掘机作业循环时间。您有什么问题，可以随时来我们网站http://www.dybocheng.com咨询了解！
