Jamming-free straw-cutting backward-bent sowing pipe

The invention aims to provide a jamming-free straw-cutting backward-bent sowing pipe. The jamming-free straw-cutting backward-bent sowing pipe comprises a backward-bent sowing pipe body, a funnel-shaped receiving port and a backward-bent straw cutter and is characterized in that the backward-bent sowing pipe body (6) is welded to the lower portion of the funnel-shaped receiving port (4), the backward-bent straw cutter (5) is welded to the front side of the backward-bent sowing pipe body (6), and a spring plastic pad (1) is adhered to the upper portion of the funnel-shaped receiving port (4). The jamming-free straw-cutting backward-bent sowing pipe has the advantages of reasonable design, simple structure, easiness in production and manufacture, simplicity and quickness in mounting and demounting, avoidance of straw hindrance and high sowing quality.
