摘要

Problem to be solved: to provide a cutting support unit to reduce the cost of the attachment and reduce the workload of attachment and removal, and to improve the loss of yield due to the fall of beans and pods when harvesting beans.The raising member 1a andA first support member 1b having a standing member andIntegrally provided with a first support memberThe entire position of the standing member is positioned forward and downward than the cutting edgeA second support member 1C having a mounting portion to be mounted on the platform andThe shaft member 2 connectable with the rotation drive shaft X of the combineBlower 3 driven by rotation of the shaft memberA main pipe 4A connected to the blower and a vent pipe 4 having branch pipes 4B corresponding to respective standing members are provided.Branch pipeThe lateral tube width has a discharge portion 4b1 that extends toward the open endFrom the dischargeAir is discharged from the predetermined position at the front and lower sides of the cutting blade to the range of 0 to several cm above the cutting blade.Diagram
