Description

Technical Field

[0001] The invention relates to the technical field of sugarcane harvesting equipment, in particular to a sugarcane harvester sterilized and disinfected by ultraviolet rays. Background Art

[0002] Existing sugarcane harvesters are usually cutting-type sugarcane harvesters, which use cutting tools to cut the sugarcane stems and collect them inside the machine or transport them to the machine's storage device through pipes. They are generally suitable for sugarcane varieties with longer stems. During sugarcane harvesting operations, some harvesters cause greater damage to the sugarcane stems, which can easily lead to losses and quality degradation. In addition, due to the lack of disinfection and sterilization devices, unsterilized cutting knives or leaf stripping devices cause secondary infection to the sugarcane, and the infected sugarcane will reduce the sugar yield.

[0003] Patent CN202310906998.0 discloses a cutting-type medium-sized sugarcane harvester with ultraviolet sterilization and a method of using the same, comprising a body support, a cockpit with a control system, wheels and a harvesting component, wherein a cockpit is installed on the top of the body support, and wheels are installed on the bottom, the front end of the body support is connected to the harvesting component, and a transmission tunnel is provided in the middle, wherein a sugarcane stalk stripping component, a cutting component, a lifting and transmission component and an ultraviolet sterilization component connected to the control system are sequentially provided in the transmission tunnel; a sugarcane leaf separator B is provided on the transmission tunnel; the ultraviolet sterilization component is provided at the cutting component and the lifting and transmission component; the patent cooperates with the cutting component and the lifting and transmission component respectively through the ultraviolet sterilization component, and performs ultraviolet sterilization respectively when the sugarcane stalk is cut and the sugarcane segments are transported, but the cutting component and the lifting and transmission component are provided after the stripping component, which means that there is still a risk of infection and mildew after the sugarcane is stripped and before it is cut.
