Abstract

The invention relates to a gravel grab bucket claw head adjustment device. The gravel grab bucket claw head adjustment device comprises a claw head, swing rods, swing lug bases, swing hydraulic cylinders and support plates, wherein the numbers of the swing rods, the swing lug bases, the swing hydraulic cylinders and the support plates are respectively two, rotation shafts are arranged at two ends of the claw head, the two swing rods are respectively located at the outer ends of the rotation shafts, one end of each swing rod is connected with each rotation shaft through a key, the other end of each swing rod is connected with each swing lug base, the tops of the swing hydraulic cylinders are fixedly connected with the bottom faces of the swing lug bases, the bottoms of the swing hydraulic cylinders are connected with the support plates, and the support plates are fixed on a grab bucket. The gravel grab bucket claw head adjustment device has the advantages of being compact in structure, simple and reliable to operate and control, low in fault rate, and capable of adjusting gradients of the grab bucket claw head, increasing the volume of gravel which is grabbed once, and improving grab efficiency.

Description

technical field [0001] The invention relates to the field of gravel grab accessories, in particular to a claw head adjusting device for a gravel grab.

Problems solved by technology

[0003] With the rise of the real estate industry in recent years, there are more and more high-rise building construction projects. Stones, an indispensable raw material, are used in house construction. Mixing stones and cement together can enhance the strength of buildings. The overall strength, the stones used in construction are first crushed by the stone crusher in the stone factory and then transported to the construction site for use. Because the weight of the stone is heavy, and the shape of the stone is sharp and different in shape, the stone is transported to the transport vehicle. The tool that must be used in the process is the grab. At present, when the grab grabs the gravel, the front end of the grab is fixed and flat, so the grab grabs the stone at one time. The volume is small, and the grabbing work efficiency is low.
