Description
Technical field
The utility model relates to a kind of pruning machinery, especially relates to the double trimmer of a kind of hand-held, and it is applicable to tea bush trimmer, also can be in order to afforestation.
Background technology
In order to improve the output of tealeaves, tea tree usually needs to prune; Trimmer on the market is of a great variety at present, mainly contains electronic, gasoline engine, single that bear and double hand steered.Chang Yong trimmer was " a portable hedgerow tea bush trimmer machine " in the past, its patent No.: 94236801.0, and it is to be made of micro machine or gasoline engine, portable cutting rack, sheave fork transmission mechanism and double sickle cutterbar; On a portable shelf, micro machine or gasoline engine are installed, by sheave fork transmission mechanism, drive double sickle cutterbar, portablely prune operation.Be applicable to the pruning operation of hedgerow and tea tree, its advantage is that the micro machine maintenance is simple and convenient, with low cost, little gasoline engine model, the operation maneuverability, adaptability is strong, still, still exists a lot of weak points, its frame for movement is very unreasonable, and run into thicker branch and block machine easily, even the damage machine; Owing to be the operation of single action cutter, its operating efficiency is very low.
Summary of the invention
The utility model mainly is that to solve existing in prior technology frame for movement unreasonable, blocks machine easily and damages technology and economic problems such as machine, inefficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: trimmer is made of frame, transmission device and cutting blade, its frame is provided with gasoline engine, be connected with cutting blade by transmission device, in transmission device, the lower end of main shaft is provided with and flies piece, fly piece and the clutch plate phase configuration that is arranged on the countershaft upper end, the countershaft lower end is provided with eccentric wheel, which is provided with described cutting blade.Because centrifugal action, high speed rotating fly piece extruding clutch plate, and phase mutual friction and drive clutch plate; when running into thicker branch; the cutting blade resistance increases, and clutch plate needs bigger moment of friction to drive, but flies piece when so big moment of friction can not be provided when what have certain rotating speed; flying piece can dally; and can not drive clutch plate, and then drive the cutter operation, with the thicker branch of cutter excision; make trimmer can not block machine, can also protect machine not damaged simultaneously.
As preferably, the countershaft lower end of described transmission device is provided with pinion, and pinion is meshed with gear wheel on the paraxonic that is arranged on countershaft one side, paraxonic be provided with eccentric wheel.Be meshed by big pinion and slow down, also can slow down by other modes.
As preferably, described eccentric wheel is made of last eccentric wheel and following eccentric wheel, and the cutter of wherein said cutting blade is arranged on the eccentric wheel, and the bottom knife of described cutting blade is arranged on down on the eccentric wheel.Under eccentric driving, two blade relative motions all the time, and prune branch.
As preferably, described main shaft is provided with blower fan, and its outside is provided with fan shroud; The wheel sheet of described blower fan is arranged on the outside of clutch plate; Described base portion of taking turns sheet is arranged on the top main shaft that flies piece, and with fly that piece is concentric to be provided with.Be provided with blower fan, more help the collection of the branches and leaves cut, collection leaf bag operated by rotary motion is in the back of fan shroud.
Therefore, the utlity model has simple in structurely, layout is more reasonable; Setting flies piece and clutch plate friction-driven mutually, helps reducing machine card machine, and the protection machine is not damaged; Setting is by two cutting blade operations simultaneously up and down that eccentric wheel drives, and characteristics such as help increasing work efficiency.
Description of drawings

Accompanying drawing 2 is A-A sectional structure schematic diagrames of Fig. 1;
Accompanying drawing 3 is a kind of main TV structure schematic diagrames of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: referring to Fig. 1, structure of the present utility model comprises frame 1, frame 1 is provided with gasoline engine 2, the two side ends of frame 1 is provided with handle 3, below the handle 3 of gasoline engine 2 sides, be provided with operating grip 4, referring to Fig. 2, the lower end of gasoline engine 2 main shafts 5 is provided with and flies piece 6, the upper end of the countershaft 9 below the main shaft 5 is provided with clutch plate 10, fly piece 6 by friction-driven and clutch plate 10 phase configuration, the lower end of countershaft 9 is provided with pinion 11, and pinion 11 is meshed with gear wheel 16 on the paraxonic 12 that is arranged on countershaft 9 one sides, paraxonic 12 be provided with one group of eccentric wheel 13, correspondence is provided with one group of cutting blade 14 on the eccentric wheel 13, wherein the base portion of cutter 141 is arranged on the eccentric wheel 131, and the base portion of bottom knife 142 is arranged on down on the eccentric wheel 132, with the frame of cutting blade 14 relative sides on be provided with collection leaf bag.
During use, adjust cutting blade 14, start 2 a few minutes of gasoline engine, the moving situation of bottom knife inspections in if afterwards blade is hot in shutdown, then should be adjusted the slit between the bottom knife.Start gasoline engine once more, can prune operation; Because centrifugal action; the piece that flies of high speed rotating pushes described clutch plate, and phase mutual friction and drive clutch plate, when running into thicker branch; the cutting blade resistance increases; clutch plate needs bigger moment of friction to drive, but flies piece when so big moment of friction can not be provided when what have certain rotating speed, and flying piece can dally; and can not drive clutch plate; and then drive the cutter operation, and promptly can not block machine, can also protect machine not damaged simultaneously.Two cutting blade operations simultaneously up and down that setting is driven by eccentric wheel can be so that operating efficiency improves greatly.
