Abstract
The utility model discloses cutterhead height stepless regulating mechanisms, including chassis, cutterhead and engine, several columns are provided on the cutterhead, casing is provided on the chassis, the column is inserted into described sleeve pipe, is arranged with spring on the column, the spring is close towards the chassis direction by the cutterhead, it further include a cam, with the top of the cutterhead against the cam rotates under the driven by engine on the outside of the cam.In use, band moving cam rotates when engine rotation, the step-less adjustment to cutterhead height is realized.In addition for the speed of driven by engine vehicle advances speed and cam rotation also in relation with getting up, we can trim out the lawn of specific shape during traveling.By replacing cam of different shapes, thus it is possible to vary the shape on lawn.
Description
Technical field
The utility model relates to a kind of grass trimmers, more particularly, to the cutterhead height adjustment mechanism on a kind of grass trimmer.
Background technique
Slot on lawn can only all be cut the same height by current grass trimmer, and such function is relatively simple, causes this
The reason of a predicament is that the cutterhead height on original grass trimmer only has limited several gears, we can only also repair lawn
Limited several height are cut into, sometimes, it is intended that by turf-mown at various shape, be especially trimmed to continuous height
The shape of variation is spent, grass trimmer general so is not just accomplished.
Summary of the invention
For the deficiencies in the prior art, the utility model provides cutterhead stepless regulating mechanism, significantly can be automatic
By turf-mown at the shape of needs.
The utility model is achieved by the following technical solution: cutterhead height stepless regulating mechanism, including chassis, cutterhead
And engine, several columns are provided on the cutterhead, casing is provided on the chassis, and the column is inserted into described sleeve pipe
It is interior, spring is arranged on the column, the spring is close towards the chassis direction by the cutterhead, further includes one convex
The top of wheel, the cam outside and the cutterhead is against the cam rotates under the driven by engine.In use, hair
When motivation rotates, band moving cam is rotated, and realizes the step-less adjustment to cutterhead height.In addition the speed that driven by engine vehicle advances
For speed with cam rotation also in relation with getting up, we can trim out the lawn of specific shape during traveling.Pass through replacement
Cam of different shapes, thus it is possible to vary the shape on lawn.
In above-mentioned technical proposal, it is preferred that the engine after a gearbox by driving the cam to rotate.Start
Generally quickly, if directly driving cam rotation not acceleration and deceleration, the height change on lawn will be too urgent for the revolving speed of machine, because
This is typically necessary by the way that band moving cam rotates again after gearbox, and in addition gearbox replaces different gears, can be not more
In the case where changing cam, the lawn of different gradient variation can be made.
In above-mentioned technical proposal, specifically, the engine drives two rear wheels by differential mechanism.
In above-mentioned technical proposal, it is preferred that the front end of the cutterhead is provided with several partitions being arranged obliquely, it is described every
Card slot is formed between plate, width of the card slot from opening to bottom gradually becomes smaller.When encountering, the grass on turf is more soft
The case where, it when trimming, possibly can not cut off, card slot can up mention the leaf that grassland is originally hung down, while when cutting, blade
It is just clamped on the bottom of card slot, facilitates blade in this way and cuts off soft blade of grass.
The utility model has the following beneficial effects: realizing in use, band moving cam moves up and down when engine rotation
To the step-less adjustment of cutterhead height.In addition the speed of driven by engine vehicle advances speed and cam rotation also in relation with getting up,
We can trim out the lawn of specific shape during traveling.By replacing cam of different shapes, thus it is possible to vary lawn
Shape.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is schematic diagram of the Fig. 1 along A-A.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Referring to Fig. 1-2, dotted portion is the part that cutterhead blocks, cutterhead height stepless regulating mechanism, including chassis in Fig. 1
1, cutterhead 2 and engine 3 are provided with 3 root posts 21 on the cutterhead 2, casing 11, the column are provided on the chassis 1
In 21 insertion described sleeve pipes 11, it is arranged with spring 4 on the column 21, the spring 4 is by the cutterhead 1 towards the chassis 1
Direction is close, further includes a cam 5, and the top of 5 outside of cam and the cutterhead 2 is against the cam 5 is in the hair
Motivation 3 drives lower rotation.The engine 3 after a gearbox 7 by driving the cam 5 to rotate.The engine 3 passes through
Differential mechanism 8 drives two rear-wheels 6 to rotate.A cover 9 is additionally provided on chassis, cover covers cam and column.
The front end of the cutterhead 2 is provided with several partitions 22 being arranged obliquely, forms card slot 23 between the partition 22,
Width of the card slot 23 from opening to bottom gradually becomes smaller.
In use, rotating when engine rotation by differential mechanism band motor vehicle rear wheel, while passing through gearbox band moving cam
The step-less adjustment to cutterhead height is realized in rotation.In addition the speed of driven by engine vehicle advances speed and cam rotation
Combine, we can trim out the lawn of specific shape during traveling.It, can be with by replacing cam of different shapes
Change the shape on lawn.
Generally quickly, if directly driving cam rotation not acceleration and deceleration, the height on lawn becomes the revolving speed of engine
Change will be too urgent, therefore is typically necessary by the way that band moving cam rotates again after gearbox, and in addition gearbox replaces different shelves
Position can make the lawn of different gradient variation in the case where being changed without cam.
When encountering the more soft situation trimming of the grass on turf, possibly it can not cut off, card slot can be by grassland sheet
The leaf to hang down up mentions, while when cutting, blade is just clamped on the bottom of card slot, facilitates blade in this way and cuts off jewelry, expensive clothing and other valuables
Blade of grass.
