Lychee picking machine

Abstract

The invention discloses a lychee picking machine comprising a machine frame and a cutting disk. The lychee picking machine also includes a lifting mechanism located on the machine frame and used for driving the cutting disk to lift and a rotating mechanism connected with the lifting mechanism and used for driving the cutting disk to rotate. The cutting disk is provided with a driving assembly fordriving the cutting disk to perform rotary cutting, and a fine adjustment mechanism for connecting the driving assembly with the rotating mechanism and used for adjusting the cutting disk to move to the lychee fruit position is also arranged between the driving assembly and the rotating mechanism. The lychee picking machine is stable in structure and high in picking efficiency. The automation degree of the lychee picking machine is high, the lychee picking positioning accuracy is improved, fruit damage is avoided, the lychee picking labor intensity and cost are greatly reduced, and the lycheepicking machine improves working efficiency and is wide in applicability range and high in practicality.

Description

technical field [0001] The invention relates to the technical field of picking, more specifically, it relates to a litchi picking machine. Background technique [0002] China is the country with the largest lychee planting area and the highest yield in the world, and it has a long history of lychee cultivation. Litchi is a unique fruit in southern my country. Its output and quality rank first in the world, accounting for 70% of the world's total output, mainly distributed in the southwest, south and southeast. At present, lychee picking is generally based on manual cutting, and there are few tools for picking on the market. In the whole production, the labor force consumed by picking fruit accounts for 33% to 50% of the whole production process, and the picking cost accounts for about 50% to 70% of the whole litchi production cost, and the picking operation is relatively seasonal. The method is not only easy to cause fruit damage, but also, untimely picking will lead to ec...

AI Technical Summary

Problems solved by technology

Although there are already many kinds of picking machines on the market, such as: mechanical pushing and shaking picking machines, mechanical impact picking machines, pneumatic shaking picking machines, and picking manipulators, there are not many picking machines designed for litchi picking

Shaking and percussion picking machines require high vibration frequency or high impact force when working, which is easy to damage the picked fruits and fruit trees; the development cost of picking manipulator is high, and the picking efficiency is low

Because the litchi skin is thin and the flesh is soft, and the distribution of the fruit is scattered, it is easy to cause a high rate of damage to the fresh fruit. It is not suitable to use the above picking machines.
