Cut device.
Background technique
China is that sugarcane production big country of the world and world's second largest sugar country of consumption, sugarcane are important industrial crops.?
China, No.1 Central File " production of emphasized development sugar material ", but sugarcane entire mechanization are the important of development China's sugar material production
Bottleneck.During the entire mechanization of sugarcane production, harvest is most important link, but the harvesting sugarcane in current China is also
Mainly manually complete.The main reason is that perennial root head breaking rate height caused by China's sugarcane mechanization harvest (root stubble splitting,
Tearing etc. cut quality problem) and the problems such as serious of uprooting seriously affected the yield of second year and aggravated the danger of pest and disease damage
Evil.
Harvesting sugarcane technology is always to limit the key technology of China's sugarcane production entire mechanization.Cutter is sugarcane again
The critical component of harvester, the quality of cutter cuts performance seriously affect sugarcane cut quality, coming year germination percentage, influence to gather in
The performance and its popularization and application of machine.Therefore, develop it is a kind of efficiently, head breaking rate is low and the cutter for the phenomenon that avoids uprooting has very
Important realistic meaning.Currently, sugar-cane cutting machine mostly uses traditional sugarcane disc cutter both at home and abroad, although research work
Persons have done many theoretical research and experimental study to it, constantly move to it, structural parameters optimize, but in reality
There are still cutting, the rate of broken sugarcane is high, cutting loss is larger, uproots the problems such as serious in work.Study carefully the main reason is that existing sweet
Sugarcane disc cutter is all based on greatly without support cutting theory, and cutting is realized by the inertia of sugarcane.In cutting process, sugarcane
Very big bending and stretcher strain occurs, to cause the splitting of root stubble, tearing and phenomenon of uprooting.And becomes and cut without support
To there is support cutting to can increase bending resistance of the stalk in cutting process, reducing bending and stretching, to improve cutting efficiency
And quality.Reduction Leifsonia head breaking rate, promotion mechanization will thus be received based on the sugarcane cutter device for thering is support to cut
Obtain and push sugarcane production entire mechanization to play important impetus.
