Recently, Qingdao Agricultural University and other units undertaken by the provincial agricultural machinery equipment research and development innovation program 'self-propelled green onion combine harvester research and development' project passed the appraisal and acceptance, of which, multi-rotary knife + U-shovel combination layered mining technology reached the international Leading level.
Scallions are economic crops with large planting area, high scale and regionalization in Shandong Province. The harvesting process is large, the mechanization level and efficiency are low, and the combined harvest is still blank, which not only affects the yield and quality of the onion, but also determines Post-harvest processing of green onions and industrial economic benefits.
The 4CL-1 type onion combine harvester developed by Associate Professor Wang Fangyan of Qingdao Agricultural University has integrated combination excavation, self-contained transport, flexible torsion and baffle stacking technology to complete the operation of green onion excavation, clamping, conveying and laying. Highly efficient operation; developed combined excavation device with multi-rotary knife + U-shovel structure to realize stratified anti-blocking excavation of soil; research and development of conveying cleaning and roller de-soiling mechanism to effectively remove the root soil of scallions; The elastic clamping conveying mechanism can adaptively adjust the spacing of the clamping belt according to the diameter of the green onion to realize the non-destructive conveying of the green onion; the flexible torsion and the partitioning mechanism of the research and development, complete the steering conveyance of the green onion, realize the steering and orderly paving of the green onion At present, I applied for 2 invention patents and obtained 4 utility model patents.
The test shows that the machine has small harvest loss, high efficiency, neatly laid green stalks, labor saving, less labor intensity, improved labor efficiency, reduced labor cost, and solved the problem of mechanized combined harvesting of green onion and mechanization of production. The foundation has effectively promoted the mechanization of the production of green onions in our province.
