挖掘机抓斗按形状可分为贝壳抓斗和桔瓣废钢抓斗,前者由两个完整的斗状构件组成,后者由三个或三个以上的颚板组成。这类挖掘机抓斗本身装有开合结构,一般用液压油缸驱动,所以由多个颚板组成的抓斗也叫液压抓钢机。一般分为四爪,五爪。
The grab of excavator can be divided into shell grab and orange leaf scrap grab according to its shape. The former consists of two complete bucket-shaped components, and the latter consists of three or more jaw plates. This kind of excavator grab itself is equipped with open-close structure, generally driven by hydraulic cylinder, so the grab composed of multiple jaw plates is also called hydraulic grab machine. Generally divided into four claw, five claw.
贝壳抓斗挖掘机一般适用于建筑地基的基坑挖掘、深坑挖掘及泥、沙、煤、碎石的装载,还有船舶、火车、汽车的装卸。桔瓣废钢抓斗(也称抓钢机)主要用于废铁废料的抓取。
Shell grab excavator is generally used for excavation of foundation pit, excavation of deep pit and loading of mud, sand, coal and gravel, as well as loading and unloading of ships, trains and automobiles. Orange scrap scrap grab (also known as grab steel machine) is mainly used for iron scrap collection.
同时这种液压抓斗针对不同的作业要求还有多种变形体,比如说抓石机,抓木机等。 不过抓石机一般很少看见使用,更常见一点的是抓木机,有些装载机上也有抓木头用的装载机抱夹
At the same time, the hydraulic grab for different operational requirements there are a variety of deformation bodies, such as stone grabber, wood grabber and so on. However, stone grabbers are rarely seen in general use, more common is the wood grabber, some loaders also have wood grabbing loader holders.
挖机抓木器与抓石器的区别在于抓斗弧度比抓石机要大,但强度不如它,一般挖掘机抓木器和抓石器都是可以360度旋转的,因为这样方便装车或是堆积。由于旋转马达和抓取油缸各自要用一组液压源,所以要在挖机臂上多布两组液管,若是发动机液压主泵阀上没有预留的阀口,还得加阀口,装置比拟费事。需要在挖掘机上添加两套液压阀块及管路来控制;
The difference between the wood grabber and the stone grabber is that the grab curve is bigger than the stone grabber, but the strength is not as good as it. Generally, the wood grabber and the stone grabber can rotate 360 degrees, because it is convenient for loading or stacking. Because the rotating motor and the grabbing cylinder each use a set of hydraulic power, so in the excavator arm to distribute two more sets of pipes, if the engine hydraulic main pump valve does not have reserved valve port, but also add valve port, device analogy trouble. It is necessary to add two sets of hydraulic valve blocks and pipelines to control the excavator.
抓木机其主要作用是进行木材、木料、芦苇、稻草及各种条状物料的装卸及搬运作业。抓石器主要装卸石块,建筑垃圾装卸及搬运。
The main function of wood grabber is to carry out the loading, unloading and handling of wood, wood, reed, straw and various strip materials. Stone grab is mainly used for loading and unloading stones, construction waste handling and handling.
