[CN 202011477525.6] Hydraulic manipulator for mining machinery
[CN 202011477525.6] Title of a hydraulic mechanical arm for mining machinery: Application number of a hydraulic mechanical arm for mining machinery: CN 202011477525.6 Applicant: Huang Chungui Application Date: 2020-12-15 Patent Type: Invention Application The present invention provides a hydraulic mechanical arm for mining machinery, including a large arm seat, the front end of the large arm seat is hinged with a large arm, a large arm oil cylinder is arranged between the large arm and the large arm seat, and the front end of the large arm is hinged with a small arm, A forearm oil cylinder is arranged between the forearm and the big arm. The cross section of the forearm is H-shaped, and a switching mechanism is installed on the surface. The upper and lower sides of the forearm are respectively provided with a breaker and a bucket. The breaker and the bucket are movably connected with the forearm through the switching mechanism, the space requirement for switching is small, and when the breaking hammer is probed out, it will synchronously drive the bucket rotation to shrink, reduce the impact of the bucket on the operation of the breaking hammer, and when the bucket is probed out, it will synchronously drive the breaking hammer to shrink, reduce the impact of the breaking hammer on the operation of the bucket, and has a good development prospect.
