A wire-driven fruit and branch harvesting and shearing device

Abstract

The invention discloses a steel-wire-driven fruit and branch picking and cutting device, wherein an outer sleeve is arranged on a lower mounting plate; the outer sleeve is internally provided with anouter bearing ring; an inner bearing ring is arranged in the outer bearing ring; the upper end of the outer bearing ring is provided with an annular saw blade; the upper end of the inner bearing ringis provided with an inner sleeve; a blanking hole is arranged on the lower mounting plate; the upper port of the inner sleeve and the outer sleeve is provided with a notch; the side wall of the bottomsurface of the notch is provided with a triangular groove; a mounting box is arranged at the lower end of a telescopic rod; a driving wheel is arranged in the mounting box; the driving wheel is connected with the outer bearing ring through a steel wire; a steel wire rubber protecting pipe is arranged between the lower mounting plate and the mounting box; the steel wire runs through the steel wirerubber protecting pipe; a protective sleeve is arranged at the lower end of the lower mounting plate and the upper end of the mounting box; the two ends of the steel wire rubber protecting pipe are propped against the protective sleeve; a detachable net bag is arranged at the lower end of the blanking hole. The device can be used for picking fruits and cutting branches, has fast picking speed, lower requirement for judging accurate positions of fruits by human eyes, fast branch trimming speed and simple and stable structure.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery equipment, in particular to a wire-driven fruit and branch harvesting and shearing device. Background technique [0002] At present, the level of agricultural mechanization in my country is still in its infancy, and the degree of mechanization of harvesting agricultural products, including fruits, is low. As an important link in the whole process of orchard production, fruit harvesting has strong seasonality and labor-intensive characteristics, and the labor force used accounts for 35% to 45% of the labor force used in the entire production process. The quality of fruit picking is related to the storage, processing and sales of fruits, which ultimately affects market prices and economic benefits. [0003] At present, picking fruits close to the ground is relatively simple, but for fruits with relatively high growth positions such as apples and oranges, pickers need to constantly cl...

AI Technical Summary

Problems solved by technology

The advantages of this picking mechanism are: simple operation, flexible adjustment of picking height, easy to pick fruits of different heights on the same tree, simple mechanical structure, moderate price, and easy maintenance; The speed is slow, the upper limbs are prone to fatigue, and the problems of fast and accurate fruit grasping have not been solved

The advantages of the fruit picking device are: simple operation, flexible adjustment of the picking height; the use of the collection function of the cloth bag to avoid frequent retraction of the pole to collect fruits; simple mechanical structure, no moving parts, easy maintenance and low cost; its disadvantages are: easy to damage The picking speed is slow, and the bag becomes heavy after multiple pickings, requiring manual lifting and pulling, which increases the burden on the pickers.

Its advantages are: the fruit can be quickly separated from the corresponding branches, the picking efficiency is slightly higher, and the separation of the fruit is more labor-saving; the disadvantage is that the human eye is required to locate the fruit position very accurately, and if the fruit is not picked up during the fruit falling process Protective measures will damage the fruit, resulting in fruit breakage

The ultimate goal of fruit picking is to bring benefits to producers. The premise of bringing benefits is the integrity and non-destructiveness of the fruit. However, due to the problems of the driving force and the executive mechanism of some machinery, the damage to the fruit is great, and there are many easy-to-injury fruits. Mechanical Root Cause Problems

[0010] 2. Lack of precise grasping ability of fruit

Although many picking mechanical devices can realize the function of grabbing fruits, they have high requirements for human eye positioning, so the success rate of precise grabbing is often low

[0011] 3. Lack of fast picking ability

Without calculating the actual picking success rate and the time it takes for workers to switch sites, each step takes about 4 seconds on average, and one picking takes more than 20 seconds
