Multi-Tooth Cutting Method and Bionic Cutter Design for Broccoli Xylem (Brassica oleracea L. var. Italica Plenck)

During the harvesting of cut-stem vegetables, structural parameters cutters have an important influence on effect. Structural stalks directly affect cutting effect cutter. The thickness stalk xylem has a strong stability and surface In this paper, broccoli conventional toothless was investigated using as object. It found that thicker leads to shear force fluctuations, which in turn affects smooth operation device. Taking locust mouthparts research object, bionic multi-tooth method is proposed paper obtain contour curve based upper jaw tooth lobe. By establishing regression equation, teeth fitted accurately. cutter edge designed with locust’s maxillary incisive lobe ANSYS software used simulate double disc stalk. each factor analyzed by response-surface determine optimal speed, machine forward inclination, blade overlap, position. test verified via bench further device operating parameters. were 0.239 m/s 30.974-degree angle, 10.066 mm 467.511 rpm.
