Description

Technical Field

[0001] The invention relates to the technical field of sugarcane harvesting equipment, in particular to a small sugarcane harvester capable of sterilizing with ultraviolet rays and microwaves. Background Art

[0002] The development of sugarcane harvesters has gone through several stages. Initially, it was manual harvesting, and then it developed to use horses and tractors as power. In the early 20th century, Australia and the United States began to mechanize sugarcane harvesting and developed two main mechanized harvesting methods: whole-stalk and cut-segment. At present, China's sugarcane harvesting mechanization level is low, and most sugarcane still relies on manual harvesting. In order to improve efficiency, my country has developed a variety of models of sugarcane harvesters, including whole-stalk and cut-segment types. These machines still need to be improved technically, especially in terms of adaptability and reliability. When using machinery to harvest sugarcane, cutting-type sugarcane harvesters are more often used, that is, cutting tools are used to cut the sugarcane stems and collect them inside the machine or transport them to the machine's storage device through pipes. This type of machine is suitable for sugarcane varieties with longer stems, and often causes greater damage to the sugarcane stems. In addition, existing sugarcane harvesters usually do not have detoxification technology, which may cause the sugarcane to be repeatedly infected with pathogens during the harvesting process, resulting in a lower sugar yield and affecting the production of the sugar industry. Sugarcane may carry a variety of bacterial and fungal pathogens, some of which are harmful to humans and animals. If the pathogens are not removed in time, during the process of picking, processing, storage and transportation, these pathogens may infect and spread diseases in humans and animals, causing adverse effects on health. At the same time, if untreated infected sugarcane is consumed, it may also cause disease transmission, thus becoming a public health issue. Utility Model Content
