Secondary re-harvesting method for peanut combined harvesting

Abstract

The invention discloses a secondary re-harvesting method for peanut combined harvesting. The secondary re-harvesting method for the peanut combined harvesting comprises the four steps of feeding, peanut picking, cleaning and peanut collecting. The feeding step is that peanut seedlings with peanuts and part of impurities enter a re-harvesting roller of a secondary re-harvesting device, wherein the peanut seedlings with the peanuts and part of impurities are originally discharged out of a vibrating screen of a peanut combine harvester and a draught fan; the peanut removing step is that the centrifugal peanut removing is carried out through a centrifugal peanut removing roller installed inside the re-harvesting roller of the secondary re-harvesting device; the cleaning step is that the stems, the leaves and other impurities produced after peanut removing are discharged out of the re-harvesting roller, the peanuts fall to the vibrating screen below the re-harvesting roller, and the vibrating cleaning is carried out on the vibrating screen to remove soil and other fine impurities; the peanut collecting step is that the peanuts on the vibrating screen enter a general peanut collecting device of the peanut combine harvester, and therefore the secondary re-harvesting is achieved. The harvesting net rate and the harvesting benefits of peanut combined harvesting can be obviously improved.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for combined harvesting and recovery of peanuts. Background technique [0002] The method of combined peanut harvesting is usually that the excavator digs the peanuts out of the ground, and then transports the peanuts to the peeling roller through the conveyor chain for peeling. Go to the fruit barn. [0003] At present, during combined peanut harvesting operations, many peanut seedlings with short roots, stems and leaves, underfull peanuts or small peanut seedlings will directly fall into the vibrating screen after passing through the roller picking roller, and then directly blown away by the vibrating screen and fan. In the field, this will cause a lot of peanuts to be scattered in the field, and the harvest will not be clean. Contents of the invention [0004] In order to improve the yield of combined peanut harvesting, prevent peanuts from being scattered o...
