The application discloses a double-arm inter-
plant weeding, deep loosening and fertilizing integrated
machine and a working method thereof. In the application, the shell is driven to move horizontally and vertically by a three-axis moving device, a ring gear box is fixed to the bottom end of the shell, when a sun gear rotates, the sun gear drives a feeding wheel to rotate through inner and outer engagement gear rings, and the inner and outer engagement gear rings and three planetary gears drive each blade of the three weeding and loosening mechanisms to rotate around the corresponding planetary gear central axis and rotate around the ring gear box central axis, the
rotating disc of each weeding and loosening mechanism forms a rotating pair with a planetary carrier, a receiving disc is fixed to the middle part of the planetary carrier and is located directly below the central through hole of the ring gear box, a valve plug forms a rotating pair with the receiving disc and the planetary carrier and is driven to vertically move by a lifting mechanism, a feeding
barrel is fixed to the ring gear box, the
discharge port of the feeding
barrel is communicated with the through hole, and a spiral feeder is arranged in the feeding
barrel, forms a rotating pair with the feeding barrel and is coaxially fixed with the feeding wheel. The application can realize the inter-
plant weeding, fertilizing and loosening work.
