The technical scheme for solving the technical problems is as follows: the utility model provides a rotary cutter for on machine is ploughed a little, hexagonal axle passes the gear box and is connected with its transmission, includes two hexagonal fixed cover, two blade holders and two cutters, two hexagonal fixed cover is established and is fixed on the hexagonal axle and is located the gear box both sides, two the blade holder corresponds to be fixed two hexagonal fixed cover is last, two the cutter corresponds to be fixed two on the blade holder and its knife tip is relative to be arranged.
The beneficial effects of the utility model are as follows: the two hexagonal fixed sleeves are sleeved and fixed on the hexagonal shaft, the two cutter seats are respectively fixed on the two hexagonal fixed sleeves, the two cutters are fixed on the two cutter seats, the cutter tips of the two cutters are oppositely arranged, the cutters are enabled to be close to the gear box, the two cutters can turn over soil corresponding to the gear box, no soil ridge is generated, and the workload is reduced.
On the basis of the technical scheme, the utility model can be improved as follows.
Further, a threaded hole is formed in the hexagonal fixing sleeve, and a bolt penetrates through the threaded hole to fix the hexagonal fixing sleeve on the hexagonal shaft.
The beneficial effect of adopting the further scheme is that: the hexagonal fixed sleeve is fixed on the hexagonal shaft by the bolts, and the structure is simple.
Further, the tool apron is a square pipe, and a notch matched with the edge angle of the hexagonal fixing sleeve is formed at one end of the tool apron.
The beneficial effect of adopting the further scheme is that: the cutter is inserted into the square tube, so that the cutter is firmer; the notch is attached to two surfaces of the hexagonal fixing sleeve, and the fixing sleeve is firmer through welding.
Further, a fixing hole is formed in the tool holder, a connecting hole is formed in the tool corresponding to the fixing hole, the tool is inserted into the tool holder, and a bolt penetrates through the fixing hole and the connecting hole to fix the tool in the tool holder.
Further, the cutter is a 195 micro-tillage cutter.
