Rod contact type lateral displacement avoiding rotary cultivator

The invention relates to a rod contact type lateral displacement avoiding rotary cultivator which comprises a traction frame, a framework, a slide rod sleeve, a slide rod, an elastic contact rod, a connecting rod, a gear box, a hydraulic lateral displacement control system assembly, a hydraulic pump and a hydraulic cylinder. The hydraulic lateral displacement control system assembly comprises a two-position four-way reversing valve and an overflow valve. The traction frame is connected with a traction machine; the slide rod sleeve is fixedly connected with the traction frame; the slide rod is arranged in the slide rod sleeve in a clearance fit manner, and two ends of the slide rod are fixedly connected with the framework; a cylinder block of the hydraulic cylinder is fixedly connected with the framework, and a piston rod of the hydraulic cylinder is fixedly connected with the slide rod sleeve; the rear of the elastic contact rod is fixedly hinged to a side of the framework, and the front end of the elastic contact rod extends out of the side of the framework; one end of the connecting rod is movably hinged to the rear end of the elastic contact rod, and the other end of the connecting rod is connected with a reversing valve spool in the two-position four-way reversing valve. The rod contact type lateral displacement avoiding rotary cultivator has the advantages that reversing instructions can be transmitted to the two-position four-way reversing valve by the elastic contact rod when the elastic contact rod is in contact with obstacles, so that the framework can laterally move towards another direction, and the purpose of avoiding the obstacles can be achieved.
