Description
Technical Field
[0001] The utility model relates to a crop harvesting robot, in particular to a spring-adaptive and highly versatile carrot harvesting robot. Background Art
[0002] Carrots, as an important crop, possess abundant nutritional and medicinal value. They are easy to store and transport, have a short growing season, and are easily arranged for crop rotation, making them a traditional disaster relief crop. They require minimal pesticide application and pose minimal pesticide pollution, making them suitable for cultivating pollution-free vegetables. Carrot cultivation also requires relatively simple field management, is less susceptible to pests and diseases, and is easily scalable.
[0003] Carrot cultivation in my country is widespread, but mostly in scattered, small plots. Influenced by factors such as soil, topography, and climate, carrot cultivation patterns vary, primarily including flat planting, ridge planting, and bed planting. The lack of uniform standards for carrot cultivation and the varying agronomic practices across different growing regions have hampered the development of carrot planting and harvesting machinery. This has resulted in a relatively low level of mechanization for carrots from planting to harvesting, particularly in the harvesting phase, which is primarily manual. This leads to high labor intensity and low efficiency for farmers, resulting in high carrot cultivation costs and low economic returns. This has directly impacted farmers' enthusiasm for carrot cultivation and hampered the development of mechanized carrot production.
[0004] Existing carrot harvesters have the following major drawbacks: poor adaptability to different soils; limited versatility for carrots with varying stem and leaf thicknesses; and poor handling of soil adhering to carrots. Specifically, soil hardness and moisture content can vary significantly across regions, with some soils being relatively hard and others relatively soft. These physical properties significantly impact the mechanical pulling force of carrots, a factor not currently addressed by carrot harvesters. Furthermore, due to variations in soil, climate, and variety, the stems and leaves of harvested carrots vary in thickness. Gripping carrot harvesters should be able to adjust the gripping mechanism based on the thickness of the carrots, but this issue is not currently addressed by carrot harvesters. During the carrot harvesting process, a significant amount of soil often adheres to the carrots, affecting their cleanliness and appearance and adding weight when they are sold. Existing harvesting equipment is ineffective at removing adhering soil, requiring secondary processing, which increases production costs and labor input. Utility Model Content
