A non-destructive fruit harvester

Abstract

The invention relates to a fruit lossless harvester and belongs to the technical field of agricultural machinery. The fruit lossless harvester comprises a bracket which is supported on a traveling mechanism, wherein the other end of a bracket cantilever and the upper end of a flapping mechanism are formed into a rotating pair; the flapping mechanism comprises a swinging rotating base at the upper end; a swinging rotating plate and a flapping rod plate are respectively arranged at the top and bottom of the swinging rotating base; a vibrating driving device is arranged on the cantilever; the vibrating driving device is connected with the swinging rotating plate through an oscillation starting mechanism; flapping rods which extend radially and then vertically are arranged on the periphery of the flapping rod plate at intervals; the cantilever which is located on the lower part of a vertical column is also arranged on the traveling mechanism; a collecting umbrella which is composed of a pair of semi-umbrellas under the flapping rods is mounted at the outer extending end of the cantilever in a folded mode through an opening mechanism; the collecting umbrella has a shape of a funnel with a leaking hole at the center; the lower side of the leaking hole is connected with the input end of a conveying mechanism; and the output end of the conveying mechanism is connected with a collecting box on the traveling mechanism. The fruit lossless harvester is suitable for picking and collecting of fruits on trees in different heights, is high in adaptability and harvesting efficiency and is low in damage to the fruits.

Description

technical field [0001] The invention relates to a harvester, in particular to a fruit non-destructive harvester, which belongs to the technical field of agricultural harvesting machinery. Background technique [0002] Fruit trees such as red dates, chestnuts, cherries and walnuts have a long history of planting, and the fruits they produce are popular nutritious products, so the planting area continues to expand. At present, such fruits are mainly harvested by simple tools such as manual tapping, air suction and fruit picking knives. In recent years, due to labor shortage and large-scale orchard planting, the cost of fruit harvest has increased year by year, and the traditional manual harvesting method can no longer meet the needs of industrialized fruit production. [0003] It is found by consulting domestic and foreign literature that Chinese patent document CN 104255197 A discloses a jujube combine harvester, which uses the mode of clamping and vibrating the trunk to mak...

AI Technical Summary

Problems solved by technology

Although this harvester reduces the difficulty of manual picking to a certain extent, it needs to repeatedly adjust the clamping position of the clamping device on the trunk during operation, and its picking method of vibrating the trunk will damage the branches and roots of fruit trees to a certain extent

Another Chinese patent document CN 104170586 B discloses a separate fruit harvester, which mainly relies on a centrifugal fan to pick and collect fruits. fruit picking

There is also a Chinese patent document CN 104737713 A that discloses a hydraulic jujube harvester, which adopts a self-propelled mode, relies on the rotating poles on both sides of the fuselage to pick the fruits on the branches, and then uses the fruit sucker to collect the fruits, but The harvester can only pick jujube trees with shorter plants, and cannot automatically harvest jujube trees with older trees and higher crowns.
