The invention discloses a gripping apparatus with a capacity-adjustable function. The gripping apparatus with the capacity-adjustable function aims at solving the problems that when the same grippingapparatus body is used for loading and unloading different types of materials, under the conditions that the gripping capacity of the gripping apparatus body is not changed and the weight of the gripped materials of the gripping apparatus body is fixed at a time, the density difference of the different types of materials (such as rice hulls, soybeans, coal, ores and mineral soil) is large, in thefull-capacity loading and unloading process of the gripping apparatus body, the weight of the gripped materials is overloaded, and safety accidents are caused; the gripping apparatus body is providedwith a hydraulic rotating device and is controlled by using an external hydraulic control valve so that the gripping and unloading directions of the gripping apparatus body can be automatically adjusted at any angle, grab bucket sections are provided with adjusting plates capable of adjusting the capacity, the adjusting plates are fixedly installed on the bucket sections through bolts, and when the materials (such as the rice hulls and the soybeans) with small material density are grabbed, the gripping apparatus body can be used for full-capacity loading and unloading operation, when the materials (such as the ore and the ore soil) with large material density are grabbed, the adjusting plates capable of adjusting the capacity can be detached, the effective grabbing capacity of the grippingapparatus body is reduced, it is guaranteed that the gripping apparatus body does not conduct overload grabbing in the operation process, and therefore safe operation is guaranteed, and meanwhile theoperation efficiency is improved. The gripping apparatus with the capacity-adjustable function is simple in structure, practical, convenient, low in labor intensity of workers, high in operation efficiency, safe, reliable, durable, and people and goods are separated.

    一种具有可调节容量大小功能的抓具,是为了解决使用同一台抓具装卸不同种类物料,在抓具抓取容量不变和一次性抓取物料重量一定的情况下,避免因不同种类物料的密度差别较大(如稻壳、黄豆、煤炭、矿石、矿土等物料),抓具在满容量装卸过程中,抓取物料的重量过载,导致安全事故的发生;抓具装配液压旋转装置,利用外接的液压控制阀控制,可任意角度自动调整抓具的抓取和卸放方向;抓具斗瓣装配有可调节容量大小的调节板,使用螺栓安装固定在斗瓣上,在抓取物料密度较小的物料(如稻壳、黄豆等),可使用抓具满容量装卸作业。在抓取物料密度较大的物料(如矿石、矿土等物料),可将调节容量大小的调节板拆除,抓具有效抓取容量减小,保证抓具在作业过程中不过载抓取,从而保证安全作业,同时提高了作业效率。本发明抓具的结构简单,实用方便,工作人员劳动强度低,作业效率高,人货分离,安全可靠,经久实用。
