The invention provides a multifunctional straw returning machine, which includes a body, the body includes a casing, and the bottom of the body is respectively provided with a stubble-cutting mechanism, a soil-breaking piece, an outlet for crushed straw, a stirring and leveling mechanism, a fertilizer discharging and discharging mechanism and a The compaction part is also provided with a PLC controller inside the body, and the PLC controller is electrically connected with the fertilizer discharging and discharging mechanism and the compaction part respectively. It not only realizes the straw returning to the field, but also realizes fertilization and sowing. One machine is multi-purpose and has high utilization rate. At the same time, it can stir the straw scraps and the soil layer, so that the straw is evenly distributed and not easily blown away by the wind. The size is automatically adjusted, so that the degree of compaction is controlled at a certain level, and the germination rate of seeds is improved. |
