Net bag detachable fruit and branch harvesting and pruning device

Abstract

The invention discloses a net bag detachable fruit and branch harvesting and pruning device which comprises a long pole. An upper face plate and a lower face plate are arranged at a tip of the long pole; an outer sleeve is arranged on the upper face plate; an inner sleeve is arranged on the lower face plate; the outer sleeve sleeves the inner sleeve; notches are formed in the upper end of the outer sleeve and the upper end of the inner sleeve; triangular oblique grooves are formed in the bottom surfaces of the notches; annular saw blades are arranged between the outer sleeve and the inner sleeve; the annular saw blades are arranged on saw sleeves; the saw sleeves are arranged on driving wheels; the driving wheels are nested in the lower end of the inner sleeve; a belt wheel is connected with the driving wheels; a rocking handle is connected with the belt wheel; a net bag fixing barrel is arranged at the lower end of the inner sleeve; hooks are uniformly arranged at the edge of the lower end of the net bag fixing barrel; a rotatable locking ring sleeves the net bag fixing barrel; locking sheets are arranged at the edge of the lower end of the locking ring, and the locking sheets andthe hooks are matched with one another to form sealing rings; a torsional spring is arranged between the locking ring and the net bag fixing barrel. The net bag detachable fruit and branch harvestingand pruning device has the advantages that fruits can be picked by the aid of the net bag detachable fruit and branch harvesting and pruning device, branches can be pruned by the aid of the net bag detachable fruit and branch harvesting and pruning device, and the net bag detachable fruit and branch harvesting and pruning device is high in fruit picking speed and branch pruning speed and has lowapple accurate location discrimination requirements on human eyes.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, in particular to a net bag detachable 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 co...

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
