Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a soil loosening mechanism for a radish harvester. Background Art

[0002] Radish is a common crop, often seen in daily diet. my country has a wide planting area for radish, and its output accounts for about 1 / 3 of the world's total output. my country's radish planting areas are mainly distributed in North China, Central China, Northwest China and some provinces in the Northeast. Most of them are planted on a large scale, and there are many varieties of radishes planted. When mechanically harvesting, usually the mechanical clamping head clamps the stems and leaves of the radish and pulls them upward to pull the rhizomes out of the picture. However, due to the different growth environments of different varieties of radishes, such as carrots and radishes, the depth of their rhizomes growing in the soil is different, and the soil compactness around the rhizomes is different. First, in the process of pulling the stems and leaves, there is a situation where the stems and leaves are broken while the rhizomes are still left in the soil, resulting in low harvesting efficiency. After searching, it was found that the prior art has reduced the breakage of stems and leaves by adding a loosening structure to the harvesting head to improve the harvesting efficiency. However, in actual operation, a single loosening structure is difficult to adapt to the different growth environments of different varieties of radishes. There is a situation where the loosening structure is not compatible with the radish growth environment, resulting in damage to the radish during the harvesting process, or the soil is not loosened properly, resulting in a still low harvesting efficiency. Therefore, the present application provides a loosening mechanism for a radish harvester to meet the demand. Utility Model Content
