DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0020] REFERENCE Figures 1-6The utility model provides a quick connection's rotary cultivator, including rotary cultivator 1, transmission shaft 2, mounting sleeve 3, base 4, limiting column 5, fixed column 6, rotary cultivator blade 7, rotary cultivator 1 is rotatably connected with transmission shaft 2, a plurality of mounting sleeve 3 are linearly installed on the surface of transmission shaft 2, a plurality of base 4 are fixedly installed on the surface of mounting sleeve 3, and the top of base 4 is equipped with installation slot, and rotary cultivator blade 7 is fixedly installed in installation slot, rotary cultivator blade 7 is provided with through groove near installation slot side, rotary cultivator blade 7 side is provided with recess, and recess is located the top of base 4, and base 4 is provided with rotary groove perpendicular to rotary cultivator blade 7 side, and limiting slot is arranged in the perpendicular both sides of rotary cultivator blade 7 in installation slot, and limiting slot and rotary groove and the through groove of rotary cultivator blade 7 side are located horizontal positional relationship.

[0021] Rotary groove is rotatably connected with limiting column 5, limiting column 5 is located in base 4, and one side is equipped with cross limiting slot, and the other side is fixedly installed with screw cap, and the both sides of screw cap are fixedly installed with protrusion, and the surface of limiting column 5 is provided with limiting block in the corresponding position of limiting slot.

[0022] Recess is provided with fixed column 6, and one side of fixed column 6 corresponds with base 4 bottom plate, and fixed column 6 is located in recess, and fixed column 6 side extends to the outside of recess and is provided with sphere, and the surface of fixed column 6 is installed with a plurality of clamping blocks, and clamping block is located below the cross limiting slot of limiting column 5.
