Description
Technical field
The utility model relates to a kind of utensil of pruning hard stem plant such as hedgerow or shrub flowers and plants, and is specifically a kind of portable, by the hedgeclipper of gasoline engine as power.
Background technology
GREEB HEDGE MACHINE is used for pruning hedgerow or prunes dwarf thicket or hard stem plant.Existing portable power GREEB HEDGE MACHINE generally comprises miniature gasoline engine, transmission case, blade, front hand grip, parts such as main handle.Drive by gasoline engine, slow down, change drive manner, thereby blade mechanisms is moved back and forth, hedgerow is pruned through transmission case.The portable power hedgeclipper is pruned for gardens and tea place and has been brought very big convenience, compares with manual hedgeclipper, for the operator has alleviated labour intensity, and has saved working time.But at present the transmission mechanism of this class machinery, that blade mechanisms exists precision is not enough, the work efficiency is not high, the operation underaction, important spare part is as defectives such as blade life are long.
Summary of the invention
The purpose of the utility model is to remedy above-mentioned defective, disclose to society a kind of reasonable in design, high efficiency, device lifetime is long, the operation light and flexible hedgeclipper.
Above-mentioned technical problem of the present utility model is solved by following technical proposals:
A kind of hedgeclipper comprises: power source gasoline engine, clutch drum gear and eccentric gear in the transmission mechanism, the connecting rod that is driven by eccentric gear, two blades, front hand grip and main handles being driven by the connecting rod of transmission mechanism.It is characterized in that, have groove on the plane of two blades, be provided with the blade protection mechanism that comprises slide block and press strip between the groove of two blades.
The slide block of described blade protection mechanism has several piece, and slide block is installed in respectively in the groove of leaving on the blade plane; Respectively there is a thin press strip long, that blade is pushed down at two up and down of slide block, above also be provided with a thick press strip on a thin press strip, several holding screws pass slide block, another thin press strip, the thick press strip in thin press strip, two insert grooves separately from bottom to up, and the space that blade is installed and operated is confined; Thick press strip, two thin press strips and slide block are fixedly attached on the transmission mechanism casing of hedgeclipper by fixed screw.
The width of described slide block matches with the width of groove, and its thickness is a bit larger tham the thickness sum of two blades.
The measure of taking for the optimization technique scheme also comprises:
The eccentric gear of described transmission mechanism and connecting rod connecting portion are provided with the needle bearing that reduces friction.
Described transmission mechanism casing adopts the extremely light magnesium alloy materials of proportion to be made.
The utility model advantage compared with prior art is:
1, is provided with the blade protection mechanism that comprises slide block and press strip between the groove of two blades.Several slide blocks of blade protection mechanism can prevent two blade double swerves, and two thin press strips can prevent that blade is crooked up and down up and down.In the time of guaranteeing the hedge trimming machine operation like this, the running of upper and lower two blades steadily and vibration-direction just, both improved operating efficiency, reduced the frictional force between two blades again, also prolonged the service life of blade.
2, the eccentric gear of transmission mechanism and connecting rod connecting portion are provided with the needle bearing that reduces friction, and have not only reduced machine members, and make transmission link turn round especially smoothly.
3, transmission case body adopts the extremely light magnesium alloy materials manufacturing of proportion to form, and reduces the weight of complete machine, can alleviate operator's labour intensity, and make flexible operation freely.

Each Reference numeral title is: gasoline engine 1, cutter 2, bottom knife 2 ', guide-leaf plate 3, front hand grip 4, main handle 5, transmission mechanism casing 6, upward thin press strip 7, following thin press strip 7 ', thick press strip 8, clutch drum gear 9, eccentric gear 10, needle bearing 11,11 ', connecting rod 12,12 ', slide block 13, holding screw 14, fixed screw 15.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, shown in Figure 4, the utility model is comprised by the transmission mechanism in power source gasoline engine 1, the transmission mechanism casing 6: clutch drum gear 9 and eccentric gear 10, by the connecting rod 12 that eccentric gear drives, cutter 2, bottom knife 2 ' and front hand grip 4, main handle 5.Guide-leaf plate 3 is concentrated the branches and leaves under pruning in the operation and is derived.Be provided with the blade protection mechanism that comprises slide block 13 and press strip between the groove of two blades.The blade protection mechanism is established six of slide blocks 13 (referring to Fig. 5), and slide block is installed in respectively in the groove of leaving on the blade plane; Respectively there is a thin press strip 7,7 ' long, that blade is pushed down at two up and down of slide block, above also be provided with a thick press strip 8 on a thin press strip 7, six holding screws 14 pass slide block 13, another thin press strip 7, the thick press strip 8 that approaches in press strip 7 ', two insert grooves separately from bottom to up, and the space that blade is installed and operated is confined.The thin press strip of thick press strip 8, two 7,7 ' and slide block 13 be fixedly attached on the transmission mechanism casing 6 of hedgeclipper by fixed screw 15.Two blades 2,2 ' thickness sum are designed to 4.5MM, and slide block 13 thickness are 4.8MM, width 5MM.Make two blades runnings can remain honest direction, not only improved operating efficiency but also prolonged service life of blade.The eccentric gear 10 of present embodiment is with upper and lower eccentric wheel, and eccentric gear and eccentric wheel are integral manufacturing (prior arts).Upper and lower eccentric wheel drives connecting rod 12,12 ' respectively, makes blade that separately driving member be arranged, and helps increasing work efficiency.Be provided with the needle bearing 11,11 ' that reduces friction with eccentric eccentric gear 10 with connecting rod 12,12 ' connecting portion.Transmission mechanism casing 6 adopts the extremely light magnesium alloy materials of proportion to be made, and makes complete machine very light and handy.
