Description

A kind of lichee picker

Technical field

The utility model relates to a kind of fruit pickers, more particularly to a kind of lichee picker.

Background technique

The regional lichee picking of the overwhelming majority at present still uses pure picked by hand, there is inefficiency, large labor intensity etc. Problem.Lichee cultivated area constantly increases in recent years, increases along with cost of labor and highlighting the problems such as labor shortage, fruit Demand of the agriculture to fruit picking machine and expectation are also continuing to increase.

Lichee class fruit acquisition mode, which mainly has, manually to be acquired, the modes such as semi-mechanization acquisition and mechanization acquisition. Mechanized harvesting efficiency is relatively high, but fruit damage, than more serious, the fruit of harvesting is only used for fruit wine, fruit juice, can etc.. And higher cost is picked in mechanical automation, is not suitable for most of middle-size and small-size orchard.For eat raw fruit, for make fruit have than Better quality, longer freshness date are relatively good using the harvesting of artificial or semi-mechanization.When manpower is picked, the fruit of eminence is then needed It picks people and carries out picking of ascending a height using tools such as stool, ladders, the efficiency of picking is very low, and the amount of labour is relatively also larger, also has There is certain risk.Therefore semi-mechanization acquisition formula auxiliary tool has a vast market foreground.

By the investigation to market, the semi-mechanization of lichee is acquired, orchard worker, which pick by means of tool, generally to be had Two kinds of Softenings:

(1) hand lever one end peace turn Y shape bayonet carry out folder pluck

(2) hand lever one end dress sickle head or scissors are picked

First method is to carry out picking lichee using Y shape bayonet, the disadvantage is that lichee can not be clamped, lichee be easy to fall and Fruit is damaged, reduces the commercial value of fruit seriously, the efficiency of picking is relatively low.

2nd kind of method is picked after cutting lichee stem using scissors, the disadvantage is that lichee stem can not accurately be cut, is held It easily cuts wrong and damages fruit, picking efficiency is also relatively low, therefore has aggravated cost significantly.

Therefore the harvest operation research for carrying out fruit, is the personal problem for safeguarding numerous orchard workers' interests.Research invention at present Fruit picker be exactly that have been directed to the difficulty of picking eminence fruit, and the shortcomings that above a few money modes optimizes, can be with Simplify picking process, improves production efficiency, have a vast market environment.

Summary of the invention

The purpose of this utility model is to provide a kind of lichee picker, it is special that the present apparatus takes lever principle structure Point, easy and light and handy design reduce the injury to fruit, and process is easy, at low cost, high-efficient, practical.

The purpose of this utility model is achieved through the following technical solutions:

A kind of lichee picker, described device include shear, fixed device, regulating device；Shear Female rivet mutually fixes shear-blade and picking plate, the stayed mast and branch knife rest and bottom knife primary and secondary being connected by Primary-secondary rivet Rivet is connected, and constitutes double rocker mechanism manipulator；The cutter of shear is connect with bolt for tool post, bottom knife and knife rest Female rivet is flexibly connected, and connection is connected with spring between stayed mast and knife rest；Fixed device is by insert rack, branch insert rack and swivel mount institute It constitutes, branch insert rack supports fixed insert rack；Regulating device is made of swivel mount, axis, sleeve bearing and bearing air cover, and bearing holder (housing, cover) is in axis On, and be embedded on swivel mount, sleeve and bearing air cover cover on axis, and bearing air cover passes through the hole insertion swivel mount on sleeve Kong Shang, bearing air cover are fixed with swivel mount；Knife rest and axis are fixed with bolt, and for bearing holder (housing, cover) on axis, it is solid that bearing is embedded in swivel mount Fixed, insert rack is connect with branch insert rack by studs and nut, and swivel mount is connect with sleeve by bearing air cover, bearing air cover set On axis, rotation messenger wire is fixed with bearing air cover, and rotation messenger wire is connect with rubber ring；Sebific duct is embedded on telescopic rod, nylon rope One is fixed with stayed mast, and one is fixed on movable rim brake across sebific duct, telescopic rod, and movable rim brake covers on telescopic rod, is used Bolt limit is fixed.

A kind of lichee picker, the shear stayed mast are connected with knife rest with Primary-secondary rivet, two structures Connection is connected with reset spring between part.

A kind of lichee picker, the sleeve, shaft coupling and axis are fixed by studs.

A kind of lichee picker, the sleeve, shaft coupling and telescopic rod are fixed by studs.

The advantages of the utility model, is with effect:

The utility model is picked suitable for eminence lichee, density.It is buckled in lichee picker and connect iron grapple Structure separation, iron is grabbed free to rotate, and the lichee string of different direction is fixed, and lichee stem is made be near the edge of a knife cutting portion of being convenient for Position, fixed iron are grabbed, and cut lichee item using nylon rope band cutting blade, tension spring restores blade；The lichee string of cutting is hooked by iron claw Firmly, it is withdrawn and is placed in basket by telescopic rod；It can directly short distance be transported after picking, improve picking efficiency, pick eminence lichee It is more safe and reliable.Device for mechanical structure, it is simple and practical adjustable, it is all detachable, it is easy-maintaining, it is at low cost.
