Vibration flapping device for harvesting fruit without damage

Abstract

The invention relates to a vibration flapping device for harvesting fruit without damage and belongs to the technical field of agricultural machinery. An output end of a horizontal axis driving device of the vibration flapping device is hinged with the upper end of a hanging ring through a vertical crank-link mechanism; the lower end of the hanging ring is connected with the upper end of a vertical guiding shaft; the guiding shaft is inserted into a guiding ring so as to form a vertical moving pair; the lower end of the guiding shaft is fixedly connected with a positioning plate with a flapping rod extending from the bottom; the guiding ring is fixed at an outer extending end of a bracket; an output end of a vertical axis driving device is hinged with one end of a swinging arm through a horizontal crank-link mechanism; the other end of the swinging arm and the guiding shaft form a peripheral constrained vertical moving pair. The horizontal axis driving device and the vertical axis driving device can be started in turn, so that the up and down vertical vibration and the peripheral torsion swinging vibration of the flapping rod can be realized in turn through the corresponding transmission mechanism, the vertical and peripheral compound vibration of the flapping rod can be realized, the high efficient harvesting of the fruit can be completed without damage to the fruit tree and the harvesting quality can be guaranteed.

Description

technical field [0001] The invention relates to a vibrating and beating device, in particular to a vibrating and beating device for non-destructive harvesting of fruit, belonging to the technical field of agricultural harvesting vibrating and beating devices. Background technique [0002] Nuts, fruits and berries such as walnuts, chestnuts, red dates, apricots, pears, apples, peaches, cherries, wolfberry and seabuckthorn have a long history of planting, and the fruits produced are all nutritious and popular, making the current The acreage of fruit trees is increasing. At present, this type of fruit mainly relies on simple tools such as manual tapping and picking, air suction and fruit picking knives. In recent years, due to labor shortage and large-scale orchard planting, the cost of fruit harvesting has increased year by year, and most fruit harvests are time-sensitive and need to be harvested on a large scale at a certain period of time. The needs of industrial productio...

Problems solved by technology

[0003] After consulting domestic and foreign literature, it is found that Chinese patent document CN 104255197 A discloses a jujube combine harvester. This machine uses the method of clamping and vibrating the trunk to make the jujube fall off the branches. The vibration picking device adopted is a telescopic arm and a linear vibrator. , the vibrating picking device can only realize the linear vibration of the trunk in a single direction, and the picking method of vibrating the trunk will damage the branches and roots of fruit trees to a certain extent

In addition, another Chinese patent document CN 104737713 A discloses a hydraulic jujube harvester. The rapping device used is a rotating bounce pole on both sides of the fuselage. Picking, for jujube trees with older trees and higher crowns, automatic harvesting cannot be realized

There is also a Chinese patent document CN 103563565 B that discloses a vibrating fruit picker, the vibration generator is a jigsaw, a saber saw or a reciprocating saw, and this type of vibration can only achieve vibration in a single direction

For forest fruit, its growth state is more complex, and the shape of the crown is different. It is difficult to achieve fruit shedding only by vibrating in a single direction. If the high-frequency trunk vibration is used for picking, it is easy to damage the root system of the fruit tree and affect the growth of the fruit tree.
