Abstract
The utility model relates to a chained hedge pruner, comprising a body (1), a guide plate (2), a chain knife assembly (3), a block cover (4), a fastening part (6) and a drive sprocket (7), etc. The chain knife assembly (3) is a closed chain iron which is composed of a chain knife (8), a connection lug (9), a drive link (10) and a chain axis(11). The utility model adopts the chain knife assembly to cut tree branches. The chain knife assembly makes a high speed turn motion under the drive of the drive sprocket, and avoids the inertial force of the reciprocating motion of the knife blades of the original hedge pruner, and thus, the production efficiency is increased, the component life and the operational reliability are improved, and the manufacturing cost and the use cost are reduced. Meanwhile, the utility model can realize the double use of one machine as a chain saw or an electric chain saw when being replaced with different work pieces, being able to be used as the chain saw or the electric chain saw, and a hedge pruner.
Description
Technical field:
The utility model relates to a kind of hand-held low-power hedgeclipper, and it is with the chain cutter type hedgeclipper of chain cutter as cutting part.
Background technology:
At present the hand-held low-power hedgeclipper that uses all adopts reciprocal cutter tooth formula beta pruning mechanism, and cutting movement is a linear reciprocating motion, and gasoline engine or electromotor are to rotatablely move, and middlely adopts the slider-crank mechanism transmission.Because blade moves back and forth and the inertia force of linkage plane motion, the hole at connecting rod two ends and pin wearing and tearing are very fast, and the life-span is too short, and use cost is higher.Simultaneously, the wearing and tearing of blade and fastenings are also very fast, influence cutting performance.In addition, because the restriction of inertia force, the cutting movement speed of blade is lower, thereby has reduced beta pruning efficient.
Summary of the invention:
The purpose of this utility model provides a kind of no reciprocating hedgeclipper, can avoid moving back and forth the various drawbacks of bringing.
The purpose of this utility model is achieved in that and adopts chain cutter type beta pruning mechanism, is made up of chain blade insert, guide plate, drive sprocket, block cover etc.The chain blade insert is made up of chain cutter, brace, drive link, chain rivet etc. again.When gasoline engine rotated, the chain blade insert was done the high speed rotary motion around guide plate under drive sprocket drives, and the chain cutter on it cuts branches and leaves.Block cover is positioned at the top of chain blade insert, and there are many catch pawls at the edge, can block branches and leaves, makes it not topple over.Chain cutter type beta pruning mechanism can exchange with the sawmilling mechanism of chain saw or electric chain saw and be installed on same the engine, realizes dual-use, both can make chain saw and use, and can work as hedgerow again and cut use.
Because the chain cutter type beta pruning mechanism that has adopted gyration, the cutting speed of cutter can improve, thereby has improved production efficiency.Chain cutter type beta pruning mechanism does not move back and forth part, has avoided reciprocating inertia force, thereby has reduced vibrations, has improved the reliability of service life of a machine and work.Chain cutter type beta pruning mechanism structure is simple, low cost of manufacture, economic benefit height.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is chain blade insert figure of the present utility model.
Among the figure 1, body 2, guide plate 3, chain blade insert 4, block cover 5, catch pawl 6, securing member 7, drive sprocket 8, chain cutter 9, brace 10, drive link 11, chain rivet
Embodiment:
Chain blade insert (3) is a closed circular chain that is formed by chain cutter (8), brace (9), drive link (10) and chain rivet (11) riveted joint, its major part is bearing on the guide plate (2), rearward end is bearing on the drive sprocket (7), meshes with drive sprocket (7).When drive sprocket (7) rotated, promptly unroll guide plate (2) and drive sprocket (7) of chain blade insert (3) done the high speed rotary motion, and chain cutter (8) just cuts branch.Block cover (4) is fixed on the guide plate (2) by securing member (6).The both sides of block cover (4) and front end have catch pawl (5).During pruning, branch can enter in the neutral gear between the adjacent catch pawl (5), and catch pawl (5) can block branch, and it can not toppled over along the cutting force of chain cutter (8), has protected carrying out smoothly of cutting seized with terror.The height of catch pawl (5) surpasses the height of chain cutter (8), can prevent the unexpected injury of chain cutter (8) to the person, plays the effect of safeguard protection.
Claims (3)
1, a kind of chain cutter type hedgeclipper is characterized in that: the beta pruning cutter is a chain blade insert (3) of doing gyration, the enclosed ring that chain blade insert (3) is made up of chain cutter (8), brace (9), drive link (10) and chain rivet (11).
2, chain cutter type hedgeclipper according to claim 1 is characterized in that: there is a block cover (4) chain blade insert (3) top, and the both sides of block cover (4) and front end have catch pawl (5).
3, chain cutter type hedgeclipper according to claim 2 is characterized in that: the height of the catch pawl (5) at block cover (4) edge surpasses the height of chain cutter (8).
