Anti-sticking fertilizer discharging wheel with soft groove bottom

The inner end of the fertilizer feeding wheel with a hexagonal hole in the middle is a cylinder, U-shaped fertilizer feeding grooves are evenly distributed in the outer end of the fertilizer feeding wheel in the circumferential direction, and the bottom of each U-shaped fertilizer feeding groove is provided with an annular-column-shaped soft rubber groove bottom, so that the anti-sticking fertilizer feeding wheel with the soft groove bottom is formed. The cylindrical soft rubber groove bottom is arranged at the bottom of the fertilizer discharging groove of the fertilizer discharging wheel of the outer-grooved-wheel fertilizer discharging device, compared with a conventional hard plastic fertilizer discharging wheel, when moisture-absorbing fertilizer is extruded to the bottom of the fertilizer discharging groove, the soft rubber groove bottom elastically deforms, fertilizer bonding is effectively prevented, and the outer-grooved-wheel fertilizer discharging device is assembled on the outer-grooved-wheel fert
