Abstract

The utility model discloses a portable hedge trimmer which comprises an engine and a trimming mechanism. The engine is fixedly arranged on a back frame and connected with the trimming mechanism through a flexible shaft, and the trimming mechanism comprises a machine frame, an eccentric wheel mechanism, a movable saw moving back and forth and a fixed saw fixed on the machine frame. The eccentric wheel mechanism is arranged on the machine frame to be connected with the flexible shaft, the movable saw and the fixed saw are arranged side by side, a sawtooth orientation of the movable saw and a sawtooth orientation of the fixed saw are identical, and the movable saw is connected with the eccentric wheel mechanism to enable rotary motion transmitted by the flexible shaft to be converted into reciprocating linear motion. The engine is carried on the back, labor intensity in operation is reduced, trimming efficiency is improved simultaneously, and the portable hedge trimmer can be widely applied to landscaping trimming.

Description

Portable hedge trimmer
Technical field
The utility model belongs to Landscape Greening Machines, is specifically related to a kind of portable hedge trimmer.
Background technology
At present, in the work of afforestation, hedgerow is pruned to the manual pruner of most employing, or adopt the hand-held power trimmer, the former is large labour intensity and efficiency is low, and the latter prunes by power, and certain efficiency is arranged, but need hand-held engine and prune mechanism, manipulation strength is large.
The utility model content
Technical purpose of the present utility model is to overcome the large or inefficient defect of labour intensity that existing hedgeclipper exists, and a kind of portable hedge trimmer is provided, and reduces the labour intensity of hedge trimming, easy to operate and efficiency is high.
The utility model adopts following technical scheme to realize above technical purpose: portable hedge trimmer, and comprise engine 2 and prune mechanism, described engine 2 is fixedly installed on backrest 3, by flexible axle 6, with described pruning mechanism, is connected; Described pruning mechanism comprises the moving saw 15 of frame 9, eccentric mechanism, back and forth movement and is fixed on and determines saw 17 on frame 9, described eccentric mechanism is arranged on frame 9 and is connected with described flexible axle 6, described moving saw 15 with surely saw 17 be set up in parallel and its sawtooth towards identical, moving saw 15 is connected with eccentric mechanism flexible axle 6 rotatablely moving of transmission is converted into to round rectilinear motion.
Described moving saw 15 is fixedly installed on slide plate 16, in the slide 13 of described slide plate 16 on frame 9, slidably reciprocates, and slide plate 16 connects to form a slider-crank mechanism by connecting rod 12 and described eccentric mechanism.
Camshaft 18 and the eccentric wheel 10 of described eccentric mechanism are connected and are arranged on frame 9 by bearing 8, and described flexible axle 6 is connected and realizes transmission of power with camshaft 18, and the bearing pin 11 on eccentric wheel 10 is connected with described connecting rod 12.
On frame 9, be provided with for hand-held handle 7.
The two ends of described flexible axle 6 are connected by shaft coupling 19 with camshaft 18 with motor output shaft 1 respectively.
Described backrest 3 is provided with the braces 5 for bearing.
The position that described backrest 3 is born is provided with cushion 4.
Engine of the present utility model adopts backpack, and the labour intensity while having reduced operation has improved pruning efficiency simultaneously, can be widely used in the pruning of afforestation.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The accompanying drawing explanation
The structural representation that Fig. 1 is the portable hedge trimmer that relates to of the utility model.
The structural representation that Fig. 2 is eccentric mechanism.
Number in the figure: 1-engine output shaft, 2-engine, 3-backrest, 4-cushion, 5-braces, 6-flexible axle, 7-handle, the 8-bearing, 9-frame, 10-eccentric wheel, 11-bearing pin, 12-connecting rod, 13-slide, the 14-hold-down screw, the moving saw of 15-, the 16-slide plate, 17-saws surely, 18-camshaft, 19-shaft coupling.
Embodiment
Embodiment
Referring to Fig. 1 and Fig. 2, the portable hedge trimmer in diagram, comprise engine 2 and prune mechanism, engine 2 is fixedly installed on backrest 3, by flexible axle 6, with pruning mechanism, be connected, backrest 3 is provided with the braces 5 for bearing, and the position that backrest 3 is born is provided with cushion 4.Pruning mechanism comprises frame 9, eccentric mechanism, the moving saw 15 moved back and forth and is fixed on and determine saw 17 on frame 9, eccentric mechanism is arranged on frame 9 and is connected with flexible axle 6, moving saw 15 with surely saw that 17 contacts are set up in parallel and its sawtooth towards identical, moving saw 15 is fixedly installed on slide plate 16, in the slide 13 of slide plate 16 on frame 9, slidably reciprocate, slide plate 16 connects to form a slider-crank mechanism by connecting rod 12 and eccentric mechanism and connects rotatablely moving that flexible axle 6 is transmitted and be converted into round rectilinear motion.On frame 9, be provided with for hand-held handle 7.
Specifically referring to Fig. 2, camshaft 18 and the eccentric wheel 10 of eccentric mechanism are connected and are arranged on frame 9 by bearing 8, the two ends of flexible axle 6 are connected and realize transmission of power with camshaft 18 with engine output shaft 1 by shaft coupling 19 respectively, and the bearing pin 11 on eccentric wheel 10 is connected with connecting rod 12.
During work, operating personnel bear backrest at back, ato unit 2, power is carried through camshaft 18 by engine output shaft 1 and flexible axle 6, camshaft 18 band movable eccentric wheels 10 rotate, drive slide plates 16 by connecting rod 12 and make to come and go rectilinear motion, thereby drive moving saw 15 and surely saw 17 the staggered action back and forth of the sawtooth realization pruning to hedgerow.
