Vine single fruit and vegetable picking robotic arm

Abstract

Provided is a vine single-fruit fruit-and-vegetable picking mechanical arm. Through linkage of each mechanism, driven only by a line sliding table, by using cooperation of a front connecting rod I, a front connecting rod II, a rear connecting rod, a roller I, a roller II, a guide rail I, and a guide rail II, expansion and retraction of the mechanical arm and reception and conveying operation of vine single-fruit fruits and vegetables under the action of gravity is realized, and driving components are reduced, and volume of the mechanisms is reduced. Before cutting the vines of target vine single-fruit fruits and vegetables, firstly, a sliding chute pushes the fruit to a large-angle inclination state, and then an upper arm clamps and fixes the vines, and the vines are cut off, so the fruit smoothly falls into the sliding chute. The mechanical arm uses a mechanism combination form to replace an original joint combination form, and a method of carrying out picking, reception, and conveying at the same time is used, the mechanical arm receives and conveys the fruits while picking the vine single-fruit fruits and vegetables, so a step of conveying the fruits after picking in a conventional mechanical arm is not needed.

Description

technical field [0001] The invention relates to a manipulator arm for picking single vine fruits and vegetables, and belongs to the field of agricultural automation equipment. Background technique [0002] With the development of science and technology and the improvement of people's living standards, my country's vegetable, melon and fruit industries are booming. In this environment, the automation of agricultural production has become an inevitable trend in the development of modern agriculture. However, the current situation of backward harvesting technology has hindered the development of the industry to a certain extent. At present, most of the harvesting of vegetables and fruits is done manually, which not only has high labor intensity and low efficiency, but also greatly increases the production cost. Therefore, the design of automatic harvesting devices has become very important. As one of the important components of the automatic harvesting device for single vine ...

AI Technical Summary

Problems solved by technology

At present, most of the robotic arms in this type of harvesting machinery in the market are multi-joint robotic arms, which are driven by multiple motors. Not only the manufacturing cost is high, but also the efficiency is low, so it is difficult to be practically applied and promoted.
