Design of root cutting device for Chinese cabbage and research on cutting simulation

Abstract

According to the characteristics of cabbage harvesting machinery, SOLIDWORKS and simulation software are used to carry out structural design and simulation analysis of its cutting device. The physical characteristics and planting status of Chinese cabbage and its rhizome were studied, and the cutting device meeting the actual harvest requirements was designed. Theoretical analysis was used to analyze the arrangement and force of the cutting knives, and a reasonable layout of the double disc knives was designed to ensure that the cabbage rhizomes could be effectively clamped and cut off, and the cutting qualification rate was improved. The virtual cutting motion simulation test of the disc rhizome cutter was carried out with ADAMS software. The movement of the single point on the knife is analyzed, and the movement law diagram of the displacement and trajectory of the single point of the knife is obtained. It is determined that the rotation of the blade can well cover the travel area to prevent missed cuts and reduce power loss. Carry out orthogonal test on the cutting device, determine the influence degree of each factor on the cutting force, and obtain the optimal parameter combination.
