Abstract

The utility model relates to a high efficiency fruit picking comb, comprising a comb hook, a telescoping rod, a guide rod, a variable-speed drive gear assembly, an arm rod, and a leather buckle. Through making use of the bending collection and the stretching motion, after the high efficiency fruit picking comb makes the amount of the motion of the bending collection and the stretching motion magnified through the variable-speed drive gear assembly, the telescoping rod is driven to move up and down; the position is optionally regulated, and the comb hook on the telescoping rod is driven to conduct the grooming type picking to the fruits. While in use, the high efficiency fruit picking comb is arranged on a fruit protecting net through winding the fruit trees for a circle under the fruit trees, and the fruit trees are groomed for a circle, and the high efficiency picking can be completed.

Description

High efficiency fruit picking device

The utility model relates to a kind of apparatus fruit picking device.

Existing fruit picking apparatus is manual operating mechanical assistance hand formula mostly, has plenty of by the fruit that is provided with on the picking lever and cuts, and fruit is overlapped and draws steel wire rope is finished fruit picking, and disclosed as No. 86202088 utility models is exactly the fruit picking device of this pattern.Have plenty of picking lever be provided with adopt a helical spring to pack into to make progress curved and curved to the right hyperbolic to the device of cramp bar finish fruit picking.Disclosed as No. 86204578 utility models is exactly the device of this form.Though these devices can carry out picking fruit, picking efficiency is not high, and picking lever can only regulate length before harvesting, can not be in the process of plucking regulated at will length, thereby its automaticity is desirable not enough.

The purpose of this utility model provides efficiently a kind of, the fruit picking device that serviceability is good.

Comb hook that the hook bar that it is 5 times to 10 times of carpopodium diameters that the purpose of this utility model is achieved in that by several spacings of bending towards consistent arc of being arranged in parallel is formed and expansion link are threaded in the expansion link upper end, expansion link places in the guide rod, slidably, expansion link one side is made tooth bar shape, a side is provided with the variable speed drives gear train on the guide rod, driven wheel in the drive gear set can mesh with the side tooth of expansion link, driven pulley with and the driving wheel that is fixed together of armed lever by driving the rope carry-over moment, driving wheel and armed lever place in the armed lever groove of lower end of the guide rod, hinged by bearing pin and guide rod, armed lever can rotate ∠ β angle relative to guide rod around bearing pin with driving wheel, lower end of the guide rod also is provided with handle and skin is buckled, and the skin button is also arranged on the armed lever.During use, hold handle, guide rod epithelium button is buckled on the elbow, armed lever epithelium button is buckled on the arm, holding handle stretches arm upwards, because the effect of armed lever and guide rod skin button, make armed lever rotate counterclockwise ∠ β angle around the relative guide rod of bearing pin together with driving wheel, the rotating torque of driving wheel is by driving rope, driven pulley, the side tooth that the change-speed gearing group is passed to expansion link makes expansion link by upwards stretching out in the guide rod, stroke for the move distance that drives rope multiply by driving wheel and change-speed gearing group gear ratio (by the gear teeth configuration relation of change-speed gearing group among the figure as can be known gear ratio greater than 1), armed lever has less rotational angle variation just can cause that the relative guide rod of expansion link has stroke greatly like this.On the contrary, the toggle of cranking arm makes handle and takes at ordinary times, and the relative guide rod of armed lever goes back to β angle of initial position ∠ clockwise, and drive gear set makes in the expansion link retraction guide rod.Crank arm repeatedly, stretch expansion link is moved up and down, drive the work of comb hook, because comb hook gap is only by carpopodium and fruit branch, the comb hook just can pull carpopodium and fruit branch tubercle place when spurring combing downwards facing to fruit, at the fruit-protecting net of fruit tree underlying one, will set one week of combing around tree and just can finish efficient harvesting around one week of tree.Use extension bar to place between comb hook and the expansion link, can finish harvesting than the high fruit tree fruit.

Embodiment further specifies the utility model below in conjunction with accompanying drawing.

Fig. 1 is an embodiment schematic diagram of the present utility model, Fig. 2 be Fig. 1 along I-I line cutaway view, Fig. 3 is the right view of the variable speed drives gear train of Fig. 1.

Among the figure 1, comb hook 2, expansion link 3, guide rod 4, variable speed drives gear combination 5, armed lever.There is tooth bar (21) on the right side of expansion link (2), and expansion link (2) places in the guide rod (3) and can vertically be free to slide.Right side, guide rod (3) upper end is provided with variable speed drives gear combination (4), and driven wheel (41) can pass through side tooth (21) engagement of the opening part and the expansion link (2) in the guide rod (3) of guide rod (3); There is handle (31) lower end of guide rod (3), skin button (32) and, pulley (33), and by bearing pin (34) with guide rod (3) with place armed lever (5) and driving wheel (44) in the armed lever groove of guide rod (3) lower end hinged.One end of armed lever (5) is provided with skin button (51), and the other end is fixing by pin (52) and driving wheel (44).Driving wheel (44) is fixing.Driving wheel (44) passes through to drive rope (43) carry-over moment with driven pulley (42).The driven wheel (41) in the variable speed drives gear combination (4) and the rotating ratio of driving wheel (44) are greater than 1.

Claims

1, a kind of efficient fruit picking comb of complying with one's wishes comprises a picking lever, and it is characterized in that: the comb hook is arranged at the expansion link top of this picking lever, and guide rod upper end one side has the variable speed drives gear combination, and there is armed lever the lower end.

2, fruit picking comb according to claim 1 is characterized in that: the comb hook is arranged in parallel by several, curves consistent arcuation, and the hook bar that spacing equates is formed, and screw thread is arranged on the neck of hook, can be screwed in the screw thread on expansion link or the extension bar.
