A UV device for potato skin ripening

Abstract

The invention discloses an ultraviolet device for potato skin ripening, comprising a left guard plate and a right guard plate. A triangular ventilation duct is arranged above the primary potato soil separation device and the secondary potato soil separation device. The triangular ventilation duct is provided with a front air outlet corresponding to the surface of the primary potato soil separation device, and the triangular ventilation duct corresponds to the secondary potato soil separation device. The surface is provided with a lower air outlet, the triangular ventilation duct is connected with a centrifugal fan, and the left and right guard plates are provided with a plurality of plant ultraviolet supplementary lights for illuminating the first-level potato soil separation device and the second-level potato soil separation device respectively. . The invention can timely improve the ripening performance of the potato skin, significantly improve the damage resistance ability of the potato skin, is conducive to the smooth implementation of subsequent potato collection, grading and other processes, comprehensively improves the operation effect of the potato combine harvester, and promotes the potato planting industry to improve efficiency and income.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an ultraviolet device for ripening potato skins. Background technique [0002] Potato is the fourth most important food crop in the world after wheat, rice and maize. At present, the large and wide range of small and medium-sized potato harvesters in China can complete excavation, potato soil separation and collection, but later potato picking, bagging, consolidating and grading still require a lot of manual work. With the development of urbanization, the shortage of labor and the high cost have become increasingly prominent. The picking cost accounts for about 10% of the price of the potato producing area, which has become the main bottleneck restricting the improvement of efficiency and income of the potato planting industry. The need for comprehensive mechanization of potato harvesting is very urgent. [0003] Large-scale potato combine harvesters can integrate...

Problems solved by technology

[0003] The large-scale potato combine harvester can integrate potato digging, separation, transportation, picking and other harvesting steps into one. Although its efficiency and automation level are high, it has not been widely promoted, mainly because of the long process of potato combined harvesting and the damage rate of fresh potato skin. The high level leads to a significant decrease in the commodity value of potatoes. Coupled with the large investment in equipment and low operational reliability, potato planting often increases production but cannot increase income.
