Detachable furrow plough with weeding function

The invention discloses a detachable furrow plough with a weeding function. The detachable furrow plough comprises a first cross rod and a second cross rod arranged on one side of the first cross rod, wherein a plurality of furrow plough mechanisms are arranged at the bottom of the first cross rod; each furrow plough mechanism comprises a furrow plough piece and a connecting rod, the furrow plough piece is welded to the connecting rod, and a threaded connection head is arranged at one end of the connecting rod; a plurality of threaded holes are formed in the bottom of the first cross rod, and the threaded connection heads are connected to the threaded holes through threads; a plurality of motors are arranged at the bottom of the second cross rod; a rotating rod is arranged at the bottom of each motor, and three weeding cutter layers are arranged on the rotating rod. The first cross rod and the second cross rod are arranged in parallel, accordingly, when the furrow plough mechanisms at the bottom of the first cross rod plough the land, the motors at the bottom of the second cross rod drive the rotating rods to rotate, accordingly, the weeding cutter layers are driven to remove weeds, land ploughing and weeding can be realized through one-time movement, resources are saved, and the working efficiency is accelerated.
