A vibration parameter testing device for fruit vibration harvesting

Abstract

The invention relates to a vibration parameter testing device for the vibratory harvesting of fruits, which comprises an experiment loading platform, a hydraulic driving system, an eccentric wheel, a connecting rod and actuating mechanisms, wherein the actuating mechanisms are divided into two groups, one group is a linear reciprocating vibration mechanism for clamping the trunk or branch of a fruit tree and then shaking on the experiment loading platform, and the other group is a reciprocating-swinging vibration mechanism for tapping a crown of the fruit tree on the experiment loading platform; a hydraulic motor of the hydraulic driving system drives the eccentric wheel to rotate on the experiment loading platform; and one end of the connecting rod is connected with the eccentric wheel, the other end of the connecting rod is detachably connected with the linear reciprocating vibration mechanism or the reciprocating-swinging vibration mechanism, and a group of the actuating mechanism is selected to be installed according to the demands of shaking or tapping the fruit tree. The device disclosed by the invention can be widely applied to the parameter testing of vibratory harvesting of fruits such as oranges, litchis, longans, red jujubes, walnuts, Chinese chestnuts, and the like, and applicable to various fruits and various vibratory harvesters of fruits; and the device is strong in commonality, and belongs to the technical field of mechanized harvesting of fruits.

Description

technical field [0001] The invention relates to fruit mechanized harvesting technology, which is applied to the test of parameters such as vibration frequency, amplitude and fruit shedding time of fruit vibratory harvesting. Background technique [0002] Fruit harvesting is an important link in the fruit production process, which requires a lot of labor, and the labor intensity is high and the harvesting cost is high. In Guangdong, artificial fruit harvesting costs have accounted for about 35% of fruit production costs. In order to reduce the cost of fruit harvesting, a lot of research has been done on fruit mechanized harvesting at home and abroad in recent years. One of them is the fruit mechanical vibration harvester, which forces the fruit to be separated from the fruit tree through mechanical vibration, which can greatly improve the fruit harvesting efficiency and reduce production costs.

AI Technical Summary

Problems solved by technology

[0005] When these existing fruit vibrating harvesters are harvesting a certain type of fruit, because the vibration frequency, amplitude, fruit shedding time and other parameters of this type of fruit vibration harvesting are unknown, it takes a long time to adapt to the test, resulting in time-consuming , high cost, and inappropriate vibration frequency and amplitude tests may damage fruit trees

There is no vibration parameter testing device for fruit vibration harvesting in the prior art
