Technical field

The floated blade and its realize the method to suspend that the present invention relates to a kind of on grass trimmer, belong to lithium battery skill Art field.

Background technique

Development of Agricultural Mechanization improves working efficiency, improves agricultural production efficiency, aobvious in our such a large agricultural countries Obtaining it is important, tool of the grass trimmer as important role in agricultural production, has most direct shadow to the yield of crops It rings.Grass trimmer be it is a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., exported by blade using the high speed rotation of engine Speed greatly improves, and saves the activity duration of weeding worker, reduces a large amount of human resources.But current grass trimmer due to Heavier-weight, and operator's both hands load-bearing rod piece own wt, and the mode of portable rod piece controls mowing height and direction, in this way It is easy to fatigue.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of floated blade on grass trimmer, passes through blade Unique design, generate upward power when rotating at high speed so that grass trimmer suspend, operator's both hands only slightly firmly Mowing height and direction, significantly load-bearing of the mitigation operator's both hands to rod portion itself are controlled, to allow entire mowing process More easily.

The present invention is realized by following proposal: a kind of floated blade on grass trimmer comprising vane body, institute It states vane body to be made of two long sides and two short sides, the centre of the vane body is provided with mounting hole, the vane body It is mounted on the driving-shaft assembly of grass trimmer by the mounting hole, each one piece of connection in two long sides of the vane body Inclined plate, two pieces of inclined plates are diagonally arranged.

Towards the outside inclined upward of the vane body, the angle with the vane body is two pieces of inclined plates 140-160 degree.

A flanging, gradually downward inclination of the flanging towards the short side are all connected on each inclined plate.

Cross-wise lines on the flanging are oblique line, and longitudinal lines on the flanging are straight line.

The vane body, the inclined plate and the flanging are an integral molding structure, and the vane body is in grass trimmer Being rotated around driving-shaft assembly under motor control.

The short side of connecting line towards side of being corresponding to it between the flanging and the inclined plate tilts.

The middle position of the vane body generally rectangle, the long side of the vane body is straight flange, and two sides are gradually It is tilted towards inside, the inclined plate is connected at the inclination in the long side.

Side of the inclined plate at the mounting hole is concave arc structure.

Two pieces of inclined plates are symmetrical relative to the diagonal line of the vane body, and two pieces of flangings are relative to the blade The diagonal line of main body is symmetrical.

A method of the floated blade on grass trimmer, which is realized, to suspend, and passes through two long sides in vane body Upper increase inclined plate is allowed to generate upward buoyancy when rotated.

The invention has the benefit that

1, a kind of floated blade on grass trimmer of the present invention is in machine use process, using the rotation of blade itself, Upward buoyancy is generated, to hold up rod portion, operator's both hands only firmly can control mowing height and direction slightly, Mitigate load-bearing of operator's both hands to rod portion itself significantly, to make entire mowing process lighter；

2. a kind of floated blade on grass trimmer of the present invention is the shape for changing vane body itself, to entirely cutting Careless process safety and blade own wt are had no effect and are increased；

3. a kind of floated blade on grass trimmer of the present invention allows operator more easily to lift rod portion, reduce knife Contact of the piece with ground, to make entire mowing process safer.

For clarity, not describing whole features of practical embodiments, in the following description, it is not described in detail well known function And structure, because they can make the present invention chaotic due to unnecessary details, it will be understood that opening in any practical embodiments In hair, it is necessary to make a large amount of implementation details to realize the specific objective of developer, such as according to related system or related business Limitation, changes into another embodiment by one embodiment, additionally, it should think that this development may be complicated and expend Time, but to those skilled in the art it is only routine work.

A kind of floated blade on grass trimmer comprising vane body 1, vane body 1 is by two long sides 2 and two Short side 3 forms, and the centre of vane body 1 is provided with mounting hole 4, and vane body 1 is mounted on the biography of grass trimmer 8 by mounting hole 4 On moving axis assembly 9, one piece of inclined plate 5 of each connection in two long sides 2 of vane body 1, two pieces of inclined plates 5 are diagonally arranged.

For two pieces of inclined plates 5 towards the outside inclined upward of vane body 1, the angle with vane body 1 is 140-160 Degree.

Cross-wise lines on flanging 6 are oblique line, and longitudinal lines on flanging 6 are straight line.

The lines parallel with short side 3 are straight line on flanging 6, and the lines parallel with long side 2 are oblique line.

Vane body 1, inclined plate 5 and flanging 6 are an integral molding structure, diagonal line of two pieces of inclined plates 5 relative to vane body 1 Symmetrically, two pieces of flangings 6 are symmetrical relative to the diagonal line of vane body 1.

The short side 2 of connecting line 7 towards side of being corresponding to it between flanging 6 and inclined plate 5 tilts.

The generally rectangle of vane body 1, the middle position of the long side 2 of vane body 1 are straight flange, and two sides are increasingly towards interior It rolls tiltedly, inclined plate 5 is connected at the inclination in long side 2.

Side of the inclined plate 5 at mounting hole 4 is concave arc structure.

Being rotated around driving-shaft assembly 9 under the motor control of grass trimmer 8 of vane body 1.

A method of the floated blade on grass trimmer, which is realized, to suspend, by the two long of vane body 1 Increase inclined plate 5 on side 2, is allowed to generate upward buoyancy when rotated.

When operation, by vane body 1 by 4 sets of mounting hole on the driving-shaft assembly 9 in grass trimmer 8, and pass through bolt 10 is fixed, 9 upper connecting rod part part 11 of driving-shaft assembly, and in 8 operational process of grass trimmer, operator holds rod portion 11, Using the rotation of vane body 1 itself, upward buoyancy is generated, to hold up rod portion 11, operator's both hands are slightly Firmly i.e. controllable mowing height and direction, load-bearing of the mitigation operator's both hands to rod portion 11 itself significantly, to allow whole A mowing process is lighter；Operator more easily lifts rod portion 11, reduces contact of the blade with ground, to allow entire Mowing process is safer.

Although having done more detailed elaboration to technical solution of the present invention and having enumerated, it should be understood that for ability For field technique personnel, modifications to the embodiments described above may be made or uses equivalent alternative solution, this is to those skilled in the art It is it is clear that these modifications or improvements without departing from theon the basis of the spirit of the present invention, belong to the present invention for member Claimed range.
