Abstract

The invention discloses a pair of novel mechanical shears, and relates to the technical field of infrastructure engineering mechanical devices. The novel mechanical shears comprise an eagle-beak-shaped upper jaw shear and a lower jaw shear matched with the eagle-beak-shaped upper jaw shear, and the upper jaw shear is hinged with the lower jaw shear; and the lower jaw shear is provided with a firstconnecting device used for being connected with a mechanical arm of an excavator, and the upper jaw shear is provided with a second connecting device used for being connected with an oil cylinder ofthe excavator. Under the driving of the oil cylinder of the excavator, the upper jaw shear can be opened and closed relative to the lower jaw shear. The novel mechanical shears not only are simple instructure, but also are easier to maintain and assemble due to modular arrangement, and an object to be sheared can be sheared off quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of infrastructure engineering mechanical devices, in particular to a novel mechanical scissors. Background technique [0002] At present, in the technical field of demolition and recycling equipment, it is often necessary to shear and demolish objects of different materials and shapes, such as iron materials, steel products, cans, pipes, and scrap cars. This requires a shearing device with strong cutting force and Simple and efficient controls. At the same time, in order to facilitate the control of the shearing device, it is also necessary to facilitate the connection and installation with the mechanical arm of the excavator. The existing steel bar shears have the problem that the opening and closing of the upper jaw shears and the lower jaw shears are small, and it is not easy to connect with the excavator. A new improvement is badly needed. [0003] Therefore, be badly in need of a kind of technical sc...
