In order to achieve better shielding and guiding effects, the projection of the air permeable grille 110 in the axial line direction of the operating handle 400 covers the opening at the upper part of the operating handle 400. At this time, the peppers fall into the cavity of the lower operating handle 400 after hitting the air-permeable grill 110, and the picked peppers are temporarily stored.
In order to cut off the stem of the picked prickly ash, a picking cutter 300 is provided outside the prickly ash suction port 101. The picking cutter 300 rotating around the axis of the pepper sucking pipe 100 cuts off the stem of the pepper tied on the edge of the port of the pepper sucking port 101.
As shown in the figure, the picking cutter 300 includes a pepper shearing ring 310 rotatably connected to the outer circumference of the pepper sucking pipe 100 and a shearing blade 320 disposed on the upper portion of the pepper shearing ring 310.
