Abstract
The utility model relates to a safely rotating blade. The novel rotating blade has the advantages of high efficiency, simple structure, and high safety; furthermore, the utility model is particularly suitable for rotating cutting machines, such as, mowers, pruners, etc. In order to solve the technical problems, the utility model has the technical scheme that a movable blade is installed between two rotary disks and the movable blade can be thrown out by centrifugal force and can be retracted by a spring.
Description
Affiliated technical field
The utility model relates to a kind of safe rotating blade, and this novel blade efficient height, simple in structure, safe and reliable is particularly suitable for rotary knife cutter tools such as mower, pruner.
Background technology
At present, the rotating blade that rotary knife cutter tools such as mower, pruner are adopted has two kinds, and a kind of is the tightrope blade, and another kind is a hard blade.Tightrope blade safety but cutting efficiency is low, the hard blade cutting efficiency is high but dangerous.
Summary of the invention
The purpose of this utility model provides a kind of safe rotating blade, solves existing tightrope blade safety but cutting efficiency is low, the high but unsafe problem of hard blade cutting efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of safe rotating blade, it is characterized in that: safe rotating blade mandrel (1) is fixedly linked with top rotary table (2) and lower rotary table (5), between top rotary table (2) and lower rotary table (5), be fixedly connected with central spindle of the spring (6) and blade mandrel (8), on central spindle of the spring (6), be connected with spring (7), on blade mandrel (8), be rotatably connected to blade (3), one end of spring (7) is fixedlyed connected with central spindle of the spring (6), and the other end of spring (7) leans on mutually with blade (3) activity.
The beneficial effects of the utility model are:
1) safety is good.
2) cutting efficiency height.
3) can be used for rotary knife cutter tools such as multiple mower, pruner.
Further specify specific structural features of the present utility model below in conjunction with Figure of description and embodiment.
Description of drawings:
Fig. 1 is the elevation cross-sectional view of overall installation diagram of the present utility model.
Fig. 2 is the vertical view of overall installation diagram of the present utility model.
Embodiment of the present utility model is:
(1) is safe rotating blade mandrel among Fig. 1, Fig. 2, and (2) are top rotary tables, and (3) are the blades when being in off working state, the blade when (4) are in running order, and (5) are lower rotary tables, and (6) are central spindle of the spring, and (7) are springs, and (8) are the blade mandrels.The annexation of this safe rotating blade is, safe rotating blade mandrel (1) is fixedly linked with top rotary table (2) and lower rotary table (5), between top rotary table (2) and lower rotary table (5), be fixedly connected with central spindle of the spring (6) and blade mandrel (8), on central spindle of the spring (6), be connected with spring (7), on blade mandrel (8), be rotatably connected to blade (3), one end of spring (7) is fixedlyed connected with central spindle of the spring (6), and the other end of spring (7) leans on mutually with blade (3) activity.
The operation principle of this safe rotating blade such as Fig. 1 are to shown in Figure 2, safe rotating blade mandrel (1) is linked to each other by the turning cylinder of rib-loop with the rotary knife cutter tool, when the turning cylinder of rotary knife cutter tool is static, blade (3) is being collected under the effect of spring (7) between top rotary table (2) and the lower rotary table (5), and blade this moment (3) can not cause unexpected injury (particularly to child etc.); When the turning cylinder high speed rotating of rotary knife cutter tool; blade (4) throws away under action of centrifugal force outside the radius of top rotary table (2) and lower rotary table (5); blade this moment (4) is in the cutting duty; running into hard thing (as stone etc.) time when blade (4) can back shrink; so both protected blade (4), and also can not damage the user.
Claims (1)
1, a kind of safe rotating blade, it is characterized in that: safe rotating blade mandrel (1) is fixedly linked with top rotary table (2) and lower rotary table (5), between top rotary table (2) and lower rotary table (5), be fixedly connected with central spindle of the spring (6) and blade mandrel (8), on central spindle of the spring (6), be connected with spring (7), on blade mandrel (8), be rotatably connected to blade (3), one end of spring (7) is fixedlyed connected with central spindle of the spring (6), and the other end of spring (7) leans on mutually with blade (3) activity.
