Abstract

The invention provides an elevating type green tea picking tool which comprises a tool handle, a tool body and a tool bit, wherein the tool handle is of a column shape and is used for fixing the tool and is connected with a transmission mechanism. The tool body comprises a tool skeleton, as well as a left tool wing and a right tool wing which extend out from the tool skeleton, and is a working part for realizing an elevating picking action. The tool bit is of a cone shape formed by narrowing the tool body and is used for guiding green tea shoots to be picked to a picking working surface. The tool is divided into three parts of the tool handle, the tool body and the tool tip, and the tool body which easily wears is conveniently replaced. The tool body is selected from a wear-resistant aluminum alloy or titanium alloy, and the tool bit and the tool handle are selected from a common aluminum alloy, so that the processing cost and the replacing cost of the tool can be reduced.

Description

The blue or green tea of a kind of hoisting type plucks cutter

Technical field

The present invention relates to blue or green tea and pluck cutter, particularly the blue or green tea of a kind of hoisting type plucks cutter.

Background technology

Tea picking lasts work that is the longest, that spend man-hour maximum in tea garden management.Concentrating and the area of lack of labor in tea place, often because plucking not in time, and having a strong impact on the Yield and qualities of tealeaves.Meanwhile, because cost of labor goes up fast, the ratio that blue or green tea harvesting cost accounts for whole Tea Production cost is more and more higher.Thus the Bi Hangzhi road that the higher mechanical picking technology of efficiency is Tea Production industry is developed.

Traditional machinery of picking tea-leaves adopts cutting Softening mostly.Because of cutting Softening easily damage blue or green tea, after developed again lifting picked technology.Promoting the principle of plucking is that the clamping of the stem of tealeaves tender shoots also upwards lifts until broken by tea picker.The operating principle that the principle that lifting is plucked and finger pluck tealeaves is close, little to the damage of blue or green tea.

Early stage lifting picker adopts rotary mostly, has both realized promoting by two cutters relatively rotated and has plucked.This mode has individual shortcoming, only have the work plane relatively rotated up can realize blue or green tea exactly and pluck, and the work plane be relatively rotated down adjacent with it can not be used, and reduces picking efficiency.Therefore, after developed the blue or green tea of swing type and promoted picker, both cutter can upwards swing left and right, and except the cutter being arranged on edge except, the left and right work plane of each cutter all can realize promoting and pluck, and improves mechanical picking efficiency of picking tea-leaves.

Summary of the invention

The invention provides a kind of swing type that can be used for and promote the cutter plucking tea picker.

Technical scheme of the present invention is as follows.

The blue or green tea of a kind of hoisting type provided by the invention plucks cutter, comprises handle of a knife, blade and point of a knife.Handle of a knife is column, is connected with transmission mechanism for fixed cutting tool.Blade comprises cutter bone and the left wing that stretches out from cutter bone and right wing, is realize promoting the working portion plucking action.Point of a knife is the taper that blade narrows formation, for blue or green tea tender shoots to be plucked is guided to plucking table.Point of a knife is the taper that blade narrows formation, for blue or green tea tender shoots to be plucked is guided to plucking table.Handle of a knife, blade and point of a knife are three individual components respectively, and blade is connected with handle of a knife, and point of a knife is connected with blade.

Described handle of a knife and blade, between blade and point of a knife by screw thread or mortise-tenon joint.

Between the left and right wing of described blade, angle is 60 °-120 °.

Described blade is made up of aluminium alloy or titanium alloy.

Described handle of a knife and point of a knife are made up of aluminium alloy.

The length of described tool nose is 2 times of blade length.

Described blade, handle of a knife and point of a knife by machining or casting technique one-body molded.

Beneficial effect of the present invention is: provide a kind of for swinging the cutter promoting harvesting formula tea picker.Cutter is divided into handle of a knife, blade, point of a knife three parts, is convenient for changing the blade part being easy to wear and tear.Blade selects wear-resisting aluminium alloy or titanium alloy, and point of a knife and handle of a knife select common aluminum alloy, can reduce processing cost and the replacement cost of cutter like this.

In figure: 1-handle of a knife, 2-blade, 3-point of a knife, the left wing of 21-, 22-cutter bone, the right wing of 23-, angle between about 24-wing.

Embodiment

Further describe technical scheme of the present invention below.

The blue or green tea of a kind of hoisting type provided by the invention plucks cutter, comprises handle of a knife 1, blade 2 and point of a knife 3.Handle of a knife 1 is column, is connected with transmission mechanism for fixed cutting tool.Blade 2 comprises cutter bone 22 and the left wing 21 that stretches out from cutter bone and right wing 23, is realize promoting the working portion plucking action.Point of a knife 3 is tapers that blade narrows formation, for blue or green tea tender shoots to be plucked is guided to plucking table.Handle of a knife 1, blade 2 and point of a knife 3 are three individual components respectively, and blade 2 is connected with handle of a knife 1, and point of a knife 3 is connected with blade 2.Handle of a knife 1 and blade 2, to be threaded connection between blade 2 and point of a knife 3.

Handle of a knife 1 is cylindric, and tail surface has screw thread, for being connected with other component.

Angle (24) between the left wing 21 of blade 2 and right wing 23 is 90 °.Between the wing of left and right, angle 24 is minimum can be 0 °, this means that left and right wing unites two into one; Maximumly can be 180 °.Between wing, angle is less, then need the stroke of swing less.Stroke is little be conducive to energy-conservation, but stroke too little being also unfavorable for control.

The length of point of a knife 3 is twices of blade 2 length.

Blade 2 is shaping through casting technique by 6070 aluminium alloys.6070 aluminium alloy wear-proof performances are good, decay resistance, and also quality is light.

It is shaping that handle of a knife 1 and point of a knife 3 pass through casting technique by 1040 aluminium alloys.Cutter is divided into handle of a knife, blade, point of a knife three parts, is convenient for changing the blade part being easy to wear and tear.Blade selects wear-resisting aluminium alloy, and point of a knife and handle of a knife select common aluminum alloy, can reduce processing cost and the replacement cost of cutter like this.
