Pre-planting mixing treatment device

The invention discloses a pre-planting mixing treatment device, and relates to the technical field of agricultural planting, and the pre-planting mixing treatment device comprises a movement mechanism connected with a mini-tiller through a rack; a power gear of the operation mechanism is fixed on an outer cylinder of the movement mechanism, a sun gear and a planet carrier of the operation mechanism are respectively connected with an inner cylinder of the movement mechanism, and power transmission between the movement mechanism and the operation mechanism is carried out, the operation mechanism is used for punching, fertilizing and mixing soil and fertilizer for planting holes before sowing of target crops. The technical problem that in the prior art, due to the fact that a fixed or single movement mode is mostly adopted, only a single working procedure can be completed, and consequently efficiency is low is solved, the mixing treatment device capable of being fixed to the mini-tiller is designed, the three wo
