Mechanical arm device for fruit harvesting

Abstract

The invention discloses a mechanical arm device for fruit harvesting. The upper end surface of a supporting ring is hinged with clamping claw bodies; the bottom surface of the supporting ring is provided with a hollow tube connected with a picking rod; the picking rod is provided with a motor box; the interior of the motor box is provided with a micro motor connected with a rotating shaft; the lower ends of the clamping claw bodies are connected with the rotating shaft through a first steel rope; the lower end of a central hole of the supporting ring is provided with buffer cylinders and a collecting bag; the lower end opening of each buffer cylinder is provided with an elastic ring; two sides of the clamping claw bodies are separately hinged with a lever; the outer ends of the levers areconnected with the interiors of the elastic rings through fourth steel ropes; the inner ends of the levers are connected with the first steel rope; the upper end of the supporting ring is provided with a telescopic cylinder; the outer ends of the levers are connected with the upper end opening of the telescopic cylinder through third steel ropes; the top end of one of the clamping claw bodies is hinged with a shearing tool; the lower end of the shearing tool is connected with second steel ropes branched by the upper end of the first steel rope; and crushing blocks are arranged at the side edgeof the shearing tool. The device disclosed by the invention has a wide application range, can simultaneously perform grasping, cutting and collecting operation, can prevent fruits against collision and damage, and greatly improves picking efficiency of the fruits.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a fruit harvesting manipulator. Background technique [0002] At present, my country's fruit planting area is large, and the task of picking is arduous. In the vast rural areas, agricultural production widely adopts diversified management, and the large-scale production and marketing of economic crops, especially fruits, enriches the people's dietary varieties and improves the people's quality of life. In many areas of the country, fruit picking is still mainly done manually. There are problems in fruit picking, such as heavy labor workload, wide operation range, high requirements for touching force control, and selective picking. Although there are also some fruit picking tools in the prior art, they are either gripping structures, or a mobile phone bag is simply arranged at the lower end of the cutting tool, and different forms of picking tools are required for ...

Problems solved by technology

In many areas of the country, fruit picking is still mainly done manually. There are problems in fruit picking, such as heavy labor workload, wide operation range, high requirements for touch force control, and selective picking.

Although there are also some fruit picking tools in the prior art, they are either gripping structures, or a mobile phone bag is simply arranged at the lower end of the cutting tool, and different forms of picking tools are required for different fruits. It is easy to cause the surface of the fruit to collide and scratch, causing the fruit skin to break and reducing the storage time of the fruit.
