Technical Field
[0001] The utility model relates to the technical field of driving harrows, in particular to a tillage harrow tooth device for a driving harrow compound drill seeder. Background Technique
[0002] A driving harrow is a harrow driven by the power output shaft of a tractor, which is a land preparation machine used for rotating and cutting to break up soil clods and level the surface soil. The working parts of the driving harrow are driven by the power output shaft of the tractor. The driving harrow has a strong soil-breaking ability and can form a suitable seedbed at one time. When the driving harrow is tilling, since the soil may contain relatively hard objects such as stones, it is easy to damage the harrow teeth of the driving harrow.
