An excavator plus a crusher bucket becomes a small mobile crushing station with low cost and high maneuverability. The jaw crusher adopts the driving method of the imported hydraulic motor directly connected to the drive shaft, which has large crushing force and excellent performance. The crushed stone size can be adjusted according to needs, high efficiency and improved construction quality. A multi-purpose machine, especially for the crushing and recycling of building concrete and the construction of mountain roads, with good flexibility and cost advantages The jaw crusher adopts advanced hydraulic technology. The motor is driven to rotate the concrete to crush the concrete, stones, etc., so that the scraps that meet the set requirements are discharged from the discharge opening, and the steel bars smaller than the discharge opening can also be simultaneously Discharge from the discharge opening.
