The curved cutting edge of the curved knife has the function of sliding cutting, is easy to cut off grass roots without winding grass, and is suitable for paddy field cultivation. The right-angle cutter has vertical and horizontal cutting edges, a wider cutter body, good rigidity and easy manufacture, but has poorer soil-entering performance. The arc-shaped knife has high strength, good rigidity and good sliding cutting effect, is usually used on a heavy rotary cultivator, and is additionally provided with various additional devices in the rotary cultivators of some countries for enhancing the cultivation effect of the rotary cultivator. For example, a rake is hung behind the rotary cultivator to enhance the soil-breaking function, and a break shovel is additionally arranged to deepen the plough layer, etc.

A hinged frame is fixedly arranged in the tool rest 4, and the tool rest 4 is rotatably connected with a plurality of groups of fan-shaped tooth sheets 24 through the hinged frame.

The using method of the invention also comprises the following steps: after the supporting mechanism supports the device, the water pump 27 is started to enable the spray head 25 to spray water to wash the blade 17, the second motor 18 is started to drive the blade 17 to rotate and slide along the transverse plate 20, the transverse plate 20 drives the rack 23 to slide in a reciprocating mode, and the rack 23 slides and drives the meshed fan-shaped toothed sheet 24 to swing in a reciprocating mode due to the fact that the fan-shaped toothed sheet 24 is connected with the knife rest 4 in a rotating mode, so that the spray head 25 swings to wash the blade 17, and the blade 17 is washed more fully due to the fact that the spray head 25 swings.
