[0002] Disc harrow is one of the important land preparation machines and has been widely used at home and abroad. It is mainly used for breaking up the soil after plowing in dry land, loosening the soil and weeding before sowing, shallow tillage and stubble removal after harvest, and field management of orchards and straw fields. At present, most of the disc harrows used in my country are equipped with tractors with more than 180 horsepower. They are mainly traction-type opposed or offset disc harrows, and use square tube welded rigid harrow frames. Multiple harrow blades, inter-tubes, bearing seats, square shafts, etc. are combined into a harrow group. There are problems such as inability to adjust, easy congestion during operation, and poor root mixing ability, which seriously affect work efficiency and work quality. In view of the many problems existing in the above-mentioned disc harrows, it is urgent to design a high-speed crushing and mixing stubble harrow for use with 120-180 horsepower tractors. The layout is reasonable, the mechanical failure rate and the failure rate of dragging piles and blocking operations are reduced, and the work efficiency and work quality are improved. It is suitable for small power and easy to promote. Utility Model Content
