A protective notch adjustable fruit picker

Abstract

The invention discloses a protective notch-adjustable fruit picker. An upper panel and a lower panel are arranged at the end of a telescopic rod; an outer sleeve is arranged on the upper panel; an inner sleeve is arranged on the lower panel; the outer sleeve sleeves the inner sleeve; notches are formed in the upper end openings of the outer sleeve and the inner sleeve; triangular chutes are formedin the bottom surfaces of the notches; an annular saw blade is arranged between the outer sleeve and the inner sleeve; the annular saw blade is arranged on a driving wheel; the driving wheel is connected with a motor; a storage battery and a switch are arranged on the telescopic rod; the storage battery and the switch are connected with the motor through wires; the outer sleeve is sleeved with anadjusting ring; supporting rods are arranged on the adjusting ring; connecting rods are arranged on the supporting rods; the connecting rods are connected with arc-shaped plates; the arc-shaped plates are arranged between the inner sleeve and the outer sleeve; the connecting rods are connected with the supporting rods through mounting bolts. The protective notch-adjustable fruit picker is low incost, free of fruit damage and high in picking speed, and has a lower requirement for judging the accurate positions of apples by human eyes, the notches can be shielded, the size and number of the notches can be adjusted, and use is more flexible and safer.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, in particular to a protective type notch-adjustable fruit picker. Background technique [0002] At present, the level of agricultural mechanization in my country is still in its infancy, and the harvesting degree of agricultural products, including fruits, is low. As an important link in the whole process of orchard production, fruit harvesting has the characteristics of strong seasonality and labor-intensiveness, 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 fruit, which ultimately affects the market price and economic benefits. [0003] At present, picking fruits close to the ground is relatively simple, but for apples, oranges and other fruits with relatively high growth positions, the picking personnel need to climb up and d...

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
