Semi-automatic ring saw fruit picker

Abstract

The invention discloses a semiautomatic ring saw type fruit picking device which comprises a telescopic rod. The ends of the telescopic rod are provided with an upper face plate and a lower face plate. An outer sleeve is arranged on the upper face plate. An inner sleeve is arranged on the lower face plate. The inner sleeve is coaxially sleeved with the outer sleeve. The upper port of the outer sleeve and the upper port of the inner sleeve are provided with notches in annular arrays. The bottom face of one side wall of each notch is provided with a triangular inclined groove opened towards thegroove wall. The bottom face of each triangular inclined groove is flush with the bottom face of the corresponding notch. A ring saw blade is arranged between the outer sleeve and the inner sleeve. The upper end face of the ring saw blade is higher than the bottom faces of the notches and lower than the top walls of the triangular inclined grooves. The ring saw blade is arranged on a saw sleeve. The saw sleeve is arranged on a driving wheel. The lower end of the inner sleeve is sleeved with the driving wheel. A bearing ring is arranged between the driving wheel and the inner sleeve. The driving wheel is connected with a motor through a transmission mechanism. A storage battery and a switch are arranged on the telescopic rod and connected with the motor through wires. The semiautomatic ringsaw type fruit picking device is low in cost, free of fruit bruises and higher in picking speed and has a low requirement for judging the precise positions of apples with the naked eyes.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, in particular to a semi-automatic ring saw type fruit picker. 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 climb up and dow...

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
