Lever type tilting cart capable of automatically loading material with small bucket

The invention discloses a lever type tilting cart for automatically loading material with a small bucket. The small bucket is arranged at the front end of a large bucket, and is hinged to extension rod outer rods; a V-shaped extension rod inner rod is nested in the other end of each extension rod outer rod; third hydraulic cylinders are mounted between the extension rod outer rods and the V-shaped extension rod inner rods; the other end of each V-shaped extension rod inner rod is hinged to a first bracket at the back side of the large bucket; the back section, near the corresponding first bracket, of each V-shaped extension rod inner rod is hinged to one end of a connecting shaft; the middle of the connecting shaft is fixedly connected with a push rod of a first hydraulic cylinder mounted on a cart body; the middle of each extension rod outer rod is hinged to a base of a second hydraulic cylinder; a push rod of each second hydraulic cylinder is hinged to one end of a connecting rod and the other end of the connecting rod is hinged to the lower end of the small bucket; the middle of each connecting rod is hinged to the corresponding extension rod outer rod and the hinged point is positioned between the corresponding second hydraulic cylinder and the small bucket. The tilting cart uses the hydraulic cylinders for controlling the small bucket to load and unload the material, has an automatic loading/unloading function, and relieves the work intensity.
