The invention relates to an active anti-blockage mechanism body, pertaining to the field of agricultural machinery. The body comprises a frame assembly, an anti-blockage trenching assembly, a fertilizing, sowing and connection assembly and a driving assembly. The anti-blockage trenching assembly, the fertilizing, sowing and connection assembly and the driving assembly are fixedly installed on the frame assembly. The anti-blockage trenching assembly comprises a stubble-cutting cutter disc, an L-shaped cutter I and an L-shaped cutter II. The stubble-cutting cutter disc is installed on a driving shaft of the driving assembly. The L-shaped cutter I and the L-shaped cutter II cling to two sides of the stubble-cutting cutter disc. The driving assembly comprises a driving shaft and a driving chain wheel. The driving chain wheel is installed on the outer end on one side of the driving shaft. The stubble-cutting cutter disc can rotate actively in the way that torque is received by chain driving and the driving shaft i
