Abstract

The utility model relates to a tea picking machine. The utility model takes a knapsack-type miniature gasoline engine for dynamic force, and passes the rotation to a flexible shaft via a clutch. The utility model is characterized in that the other end of the flexible shaft is butted with a speed reducer input shaft that is arranged in a tea collecting bucket, and a cam is arranged on an output shaft of the speed reducer; the cam contacts a shift fork block whose one end is provided with gear teeth, and the gear teeth on the shift fork block are in mesh with toothed racks at the rear side of movable blades that are fixed in a blade group; a reset mechanism is arranged on the shift fork block or on the movable blades, the shift fork block is positioned on the collecting bucket via a shaft, and the blade group is fixed on the collecting bucket via a limiting pressing block and a positioning pin shaft. The tea picking machine has the advantages of simple structure and small volume.

Description

Tea picking machine

The utility model belongs to agricultural machinery, particularly a kind of tea picking machine of gathering tealeaves.

At present, domestic vast rural area, Cha Qu harvest tea leaves, and main dependence is manual wins, and there is the large-scale machinery of picking tea-leaves of employing on indivedual large-scale farms, tea plantation, but because of its cost very high, want a few people's co-operatings during use, can't popularize, and non-standard tea place can't be used at all.Existing a kind of shoulder carrying mower, be power mainly by bearing the minitype gasoline engine, through clutch flexible axle is passed in rotation, stiff shaft in one end of flexible axle and the hand-held grass cutter joins, the rigidity the tip of the axis is equipped with mowing cheese or circular saw, and the mowing cheese of high speed rotating or circular saw are used for mowing or pruning twig.

The purpose of this utility model is to utilize the operation principle of shoulder carrying mower, designs a kind of in light weightly, and volume is little, the automatic tea plucker of band minitype gasoline engine.

Task of the present utility model is to realize like this, to bear the minitype gasoline engine is power, through clutch flexible axle is passed in rotation, the other end reducer input shaft interior with being located at the tealeaves collection bucket that it is characterized in that flexible axle docks, establish a cam on the output shaft of decelerator, cam touches mutually with the shift fork piece that an end is provided with teeth, teeth on the shift fork piece be fixed on set of blades in the tooth bar of movable blades rear side be meshed, shift fork piece or movable blades are provided with resetting-mechanism, the shift fork piece is fixed on the collection bucket by axle, and set of blades is fixed on the collection bucket by spacing briquetting and alignment pin.Petrolic rotary power is passed to movable blades in the set of blades through flexible axle, decelerator, movable blades moves reciprocatingly under power and resetting-mechanism effect, cooperate with fixed blade and to finish shear action, during use, bear the hand-held tealeaves collection bucket of minitype gasoline engine, the edge of a knife of set of blades is aimed at the tea strain can shear newly picked and processed tea leaves or the strain of finishing tea.

The utlity model has novelty simple in structure, volume is little, and is in light weight, safe and convenient to use, the characteristics that efficient is high, and can be extended to numerous areas such as city trees and shrubs maintenance, be the high apparatus of a kind of ratio of performance to price.

Below in conjunction with concrete legend the utility model is described further:
