The invention discloses a duplex intertillage weeding
machine which can be used for completing the processes of performing side deep fertilization, performing soil loosening and weeding among seedlings, performing ridging, performing earth up, performing deep
scarification and the like in the intertillage process. The duplex intertillage weeding
machine comprises a soil covering
shovel, a soil covering
shovel bracket, a profiling single body, a tensioning spring and a four-bar linkage, a profiling mechanism suspension bracket, a
fertilizer box, a
fertilizer discharging wheel, a
fertilizer boxsupport, a
machine frame, a middle shaft, ground wheels, a ground wheel support, a fertilizer discharging furrow opener, a deep-
scarification shovel base, a deep-
scarification shovel
handle, a weedingsingle body gear box, a comb tooth roller, a lifting rod, a profiling wheel, comb teeth, an adjusting screw rod, and a profiling wheel bracket, wherein during operation, the ground wheels transmit power to a fertilizer discharging shaft, and drives the fertilizer discharging shaft to apply fertilizer; the fertilizer is conveyed to the side deep fertilizing furrow opener through a fertilizer spreading
pipe for realizing the ridging side deep fertilizing; the weeding device drives the vertical rotating spiral comb tooth type weeding device to work; and the deep scarification operation is completed by the shovels; and the soil covering device is used for covering soil. The duplex intertillage weeding machine has the characteristics of novel structure, safety and reliability, low cost, automatic operation and the like.
