The invention discloses a robot production line for producing organic fertilizer, and relates to the technical field of organic fertilizer production. The robot production line comprises a grinding device, a first mixing box, a drying box, a second mixing box, a storage box, a packaging device and a lifting mechanism; the grinding device, the first mixing box, the drying box, the second mixing box, the storage box and the packaging device are arranged in sequence, and the lifting mechanism comprises a first lifting device, a second lifting device and a third lifting device; and a first conveying pipe is fixedly connected to the bottom end of the grinding device. The robot production line can perform multiple grinding on organic fertilizer raw materials by the grinding device, the grindingeffect on the organic fertilizer raw materials is good, the vertically arranged lifting mechanism can reduce the length of the production line, the occupied area of equipment is reduced, the space utilization rate of an enterprise workshop is increased, the drying speed of the organic fertilizer raw materials can be accelerated by arranging dispersing claws, the production efficiency is improved,the robotic automation operation in the whole process is achieved, the work efficiency is high, and the production speed is high.
