Description

Mining crushing trolley with protection function Technical Field The utility model relates to the technical field of mining machinery, in particular to a mining crushing trolley with a protection function. Background In mining and ore crushing operations, a mining crushing trolley is an important mechanical device and is widely applied to primary crushing and secondary crushing of ores, the crushing trolley is generally provided with a hydraulic driving mechanical arm, a crushing hammer or other crushing tools are arranged on the mechanical arm and are used for crushing the ores efficiently, however, in the actual operation process, an oil cylinder part of the mechanical arm is often directly exposed, the moving end of the oil cylinder is easily impacted by ore scraps generated in the crushing process, the ore scraps are easily adhered to the moving end of the oil cylinder, the oil cylinder is worn, and the service life and the working efficiency of the equipment are seriously affected. Disclosure of utility model The utility model aims to provide a mining crushing trolley with a protection function, which aims to solve the problem that the cylinder part of a mechanical arm provided in the background art is always directly exposed, the moving end of the cylinder is easily impacted by ore scraps generated in the crushing process, and the ore scraps are easily adhered to the moving end of the cylinder. The mining crushing trolley with the protection function comprises mobile equipment, wherein a mechanical arm and a first oil cylinder for driving the mechanical arm to pitch are arranged on the mobile equipment, a crushing head and a third oil cylinder for driving the crushing head to change angles are arranged on the mechanical arm, the mechanical arm comprises a plurality of stages of support arms which are sequentially hinged, a second oil cylinder is hinged between every two adjacent support arms, and protection pieces are arranged at the mobile ends of the first oil cylinder, the second oil cylinder and the third oil cylinder and are respectively positioned at one side, far away from the mechanical arm, of the first oil cylinder, the second oil cylinder and the third oil cylinder. Preferably, the movable end and the fixed end of the first oil cylinder, the second oil cylinder and the third oil cylinder are respectively provided with a hinge piece. Preferably, the three groups of the protecting pieces are respectively arranged on the hinging pieces positioned at the moving ends of the first oil cylinder, the second oil cylinder and the third oil cylinder.
