Experiment and Analysis of the Harvest and Picking Ability of Peanut

In order to reduce the peanut drop and picking ability during the peanut digging and harvesting process, the three peanut varieties mainly promoted and planted in Henan Province were used as the research object, and the electronic universal testing machine, moisture meter and other related test equipment were used to control the digging and drying. The water content of each part of the peanut plant varies with the drying time, the fruit stalk and the pod axis are coaxial, and the fruit picking power at different stretching angles is determined. The water content changes and mechanical properties of peanut stems, stalks and pods were studied when the water content of the three peanut varieties was excavated to about 10%. The moisture content of peanut plants is 50%-75% when they are just excavated, and the moisture content is basically reduced to 10% after 6-7 days of drying, and the moisture content changes asymptotically; in the initial stage of drying, the peanut picking power increases rapidly with the prolonging of drying. The fruit picking power of the three varieties was 18.91-23.04 N when they were first excavated, and the fruit picking power dropped to 9.83-12.27 N after 6 days of drying; the probability of the fracture position an the stalk node during fruit picking increased with the moisture content. The reduction of the fruit picking power increased from 70% to about 80%; the fruit picking power at different stretching angles decreased first and then increased. The fruit picking power was the smallest when the stretching angle was 30°; the picking and harvesting drying time was initially determined for 3-4 days. The fruit picking power is the least. The research results can not only provide the best harvest time for the two-stage picking and harvesting machine, but also provide a certain reference for the picking angle of the fruit picking drum for both flower and seedling and fresh and wet peanut harvesting.
