Description

TECHNICAL FIELD

[0001] The present application relates to a Chinese cabbage root cutting part, in particular to a Chinese cabbage harvester pulling transmission root cutting part, and belongs to the field of agricultural machinery. BACKGROUND

[0002] Chinese cabbage is suitable for planting in high latitude regions with large diurnal temperature difference, sufficient light, and less disease and insect pests, which is beneficial to nutrient accumulation of Chinese cabbage, formation of compact leaf ball and sweet taste, and extension of growth period in the north before frost, thereby improving yield and quality. Key core technology for realizing automatic harvesting of Chinese cabbage is how to orderly pull out Chinese cabbage from the ridge, set the root cutting height position according to requirements, ensure the consistency and stability of the root cutting height position, keep Chinese cabbage in a clamped state without shaking during the root cutting process, and smoothly transmit Chinese cabbage to the rear. At present, most Chinese cabbage harvesters directly cut the roots of Chinese cabbage on the ridge by two rotating cutter discs, so that the root cutting height position of Chinese cabbage is inconsistent or missed, and Chinese cabbage is clamped by two wide flat belts or two special belts with recesses for transmission to the rear. Since the diameter of the Chinese cabbage body part varies, the clamping force is unstable, Chinese cabbage slides or falls off, and the breakage rate of Chinese cabbage is relatively high, which directly affects the harvesting efficiency and quality of Chinese cabbage.
