Detailed description of the invention

Refer to Fig. 1～2, this utility model preferred embodiment provides a kind of grass-mowing machine 100, and this grass-mowing machine 100 includes Head, handle assembly 110 and the connecting rod 120 being located between head and handle assembly 110.Wherein include can be around an axis for head The cutting member 131 rotated.Cutting member 131 high speed rotating under the driving of motor forms cutting planes, such that it is able to beat the grass Operation.Head is provided with determines guard shield 132, rotating dynamic guard shield 133；And for controlling the controlling organization that dynamic guard shield 133 rotates. Handle assembly 110 can include one or more handle 111 and grip part 112.Be a D-shaped handle 111 herein and one hold Hold portion 112.The housing of this grass-mowing machine 100 is provided with battery bag, and battery bag provides electric energy for this grass-mowing machine 100.Certainly, this is beaten the grass The mode that machine 100 can also use power line to be connected with external power source provides electric energy for this grass-mowing machine 100.

During use, operator can grip handle assembly 110, is then turned on controlling switch and controlling organization, and electric energy just may be used With from battery bag to motor transmission, motor rotates and drives cutting member 131 to rotate, and moves guard shield 133 simultaneously and opens to expose and cut Cutter member 131.Now cutting member 131 is directed at by operator needs the turf of cutting just can realize operation of beating the grass.Beat the grass end Time, operator's closing control switch and controlling organization, battery bag stops the transmission of electric energy, and cutting member 131 stops the rotation, simultaneously Controlling organization cuts out dynamic guard shield 133 and cuts out to protect moving head.Dynamic guard shield 133 and determine the setting of guard shield 132 and can't affect The normal use of this grass-mowing machine 100, simultaneously when grass-mowing machine 100 stops operation, additionally it is possible to full protection lives grass-mowing machine 100, this The grass-mowing machine 100 of sample is difficult to safely hurt sb.'s feelings.

Controlling organization controls the rotation of dynamic guard shield 133.When use grass-mowing machine 100 carries out beating the grass operation, controlling organization control Braking guard shield 133 rotates to expose cutting member 131 so that it is can normal operation.When operation is beaten the grass in stopping, controlling organization controls Dynamic guard shield 133 rotates to protect cutting member 131, prevents cutting member 131 from hurting people.

Referring to Fig. 3～4, controlling organization includes being located on handle assembly 110 for opening or closing dynamic guard shield 133 Operating parts 141.It is understood that operating parts 141 is the button for operator's operation, i.e. operator are grasped by operation Workpiece 141 realizes controlling the rotation of dynamic guard shield 133.When operator's push part 141, then rotate dynamic guard shield 133, move and protect Cover 133 is rotated such that cutting member 131 comes out and cuts.In order to anti-stop guard shield 133 is beaten the grass at grass-mowing machine 100 During operation, impact is beaten the grass, and makes convenient operation and control, and operating parts 141 is arranged at grip part 112.So, operation is worked as Personnel grip grass-mowing machine 100 carry out beating the grass operation time, operating parts 141 is constantly in the state of being pressed, and cutting member 131 can always It is in and is exposed to outer state, do not interfere with operation of beating the grass normally, and without being additionally operable to control.

Referring to Fig. 5, controlling organization includes that movable pulley 142, one end are connected on dynamic guard shield 133 and the other end is walked around The first control line 143 that movable pulley 142 is fixed in connecting rod and be connected to the second control of movable pulley 142 and operating parts 141 Line 144.It is internal that movable pulley 142 is arranged at connecting rod 120.When push part 141, then be equivalent to pull the second control line 144 (direction to away from cutting member 131).So movable pulley 142 moves to the direction away from head in connecting rod 120 inside, first Control line 143 pulls dynamic guard shield 133, and dynamic guard shield 133 cannot be carried out mobile, and is converted to the rotation of dynamic guard shield 133.This is dynamic sliding The effect of wheel 142 setting is change motion and is formed.Such as when push part 141, the second control line 144 moves 1 millimeter, Due to the effect of movable pulley 142, the girth that last movable pulley 142 rotates is 2 millimeters.

In other embodiments, it is possible to directly by connecting line attended operation part 141 and dynamic guard shield 133.I.e. connecting line is worn Crossing connecting rod 120, one end is fixed on operating parts 141, and the other end is fixed on dynamic guard shield 133.When push part 141, Connecting line is pulled, and the displacement of connecting line is directly converted to the rotation of dynamic guard shield 133.Concrete takes which kind of mode then basis Concrete operating mode needs specifically to determine.

Move guard shield 133 and determine the equal semicircular in shape of guard shield 132, and the size of dynamic guard shield 133 is less than determining guard shield 132.So using Grass-mowing machine 100 carry out beating the grass operation time, dynamic guard shield 133 rotates, and is turned directly to determine in guard shield 132.When operation is beaten the grass in stopping, Dynamic guard shield 133 rotates, in complete circle on the direction be perpendicular to cutting planes.

In other embodiments, the size of dynamic guard shield 133 can also be more than determining guard shield 132.So carry out with grass-mowing machine 100 Beat the grass operation time, dynamic guard shield 133 rotates, and is turned directly to determine outside guard shield 132.

Controlling organization also includes back-moving spring 145.Back-moving spring 145 one end is connected on dynamic guard shield 133, and the other end connects In determining on guard shield 132.Grass-mowing machine 100 carry out beating the grass operation time, back-moving spring 145 is in extended state.Once grass-mowing machine 100 stops Only beating the grass operation, operating parts 141 is released, and the elastic force of back-moving spring 145 pulls dynamic guard shield 133 to rotate, and protects cutting member 131。

Above-mentioned grass-mowing machine 100 includes dynamic guard shield 133, determines guard shield 132 and control the controlling organization that dynamic guard shield 133 rotates.When Use grass-mowing machine 100 carry out beating the grass operation time, controlling organization controls dynamic guard shield 133 and rotates and expose cutting member 131, do not affects Moving head is beaten the grass operation normally.When grass-mowing machine 100 stops operation, controlling organization controls dynamic guard shield 133 and rotates to protect Cutting member 131.This grass-mowing machine 100 is unaffected in operation of normally beating the grass, and is also protected when not operation, cutting member 131 Will not harm people, such grass-mowing machine 100 is safe and reliable does not hurts sb.'s feelings.

Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited In contradiction, all it is considered to be the scope that this specification is recorded.

Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the common skill of this area For art personnel, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
