Portable highly adaptive picking device for high-altitude fruit strings

Abstract

The invention provides a portable highly adaptive picking device for high-altitude fruit strings. The device is characterized by being composed of a tripod, three telescopic swing rods, an electric push rod, a supporting plate, a splicing sleeve pipe, a splicing rod and a harvesting mechanism. The electric push rod is connected with the tripod through a spherical hinge, and the tripod, the telescopic swing rods, the electric push rod and the supporting plate form a spatial hinged four-rod mechanism. Each telescopic swing rod is provided with an electromagnet, the position is locked when the electromagnet is electrified, and arbitrary angle positioning of an intermediate support rod of the device is achieved. The harvesting mechanism is a multi-degree-of-freedom manipulator containing a circumferential rotating joint, a collecting frame joint, a first rotating joint, a second rotating joint, a third rotating joint and a top cutting mechanism. The device is simple in structure, wide in working range, small in size, light and convenient to install, meets the picking requirements of litchi, longan and other high-altitude fruit strings, and is of great significance for improving the level of agricultural machinery in China.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a high-altitude fruit string fruit picking device, in particular to a portable high-altitude fruit string high adaptability harvesting device suitable for litchi, longan and the like. Background technique [0002] Litchi, longan, etc. are the characteristic fruits in southern my country, and they are also the main agricultural economic crops in the area. As we all know, fruits such as lychee and longan grow in clusters, commonly known as cluster fruits. It generally grows on trees with a height of about 10 meters, and the growth position of the bunch of fruits is 3-5 meters above the fruit tree. Phase directly affects the selling price. At present, the picking of this kind of fruit is mainly manual picking, which is not only labor-intensive but also difficult to pick, especially the high-altitude operation of manual picking is extremely dangerous. It can be said that the cost of picki...
