Description

A kind of double blade mowing-apparatus
Technical field
The present invention relates to the mower field, particularly a kind of double blade mowing-apparatus.
Background technology
Existing single blade mower swath scope is less, makes intensity of workers big, and adopts the bigger single blade mower of swath, because radius of turn is bigger, need be more high-power, and noise and vibration exceeding the standard waste energy, and have increased cost.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: provide a kind of noise little with vibration, reduce power demand significantly, the double blade mowing-apparatus of energy efficiency.
The technical scheme that the present invention adopted is: a kind of double blade mowing-apparatus; Comprise housing; At least be provided with first motor and second motor in the housing, the output shaft of said first motor is provided with first blade, and the output shaft of said second motor is provided with second blade; Be provided with before and after said first blade and said second blade stagger in housing, first blade and second blade are along the upright projection of mower moving direction partial stack at least.
In preferred embodiment of the present invention, said first blade and the second blade setting are at grade.
In preferred embodiment of the present invention, be respectively arranged with fan blade between said first blade and first motor, said second blade and second motor.
In preferred embodiment of the present invention, the rotation direction of said first motor and said second motor is opposite.
In preferred embodiment of the present invention, also be provided with the 3rd motor in the said housing, said first motor, second motor, the 3rd motor are the triangle setting.
In preferred embodiment of the present invention, the axis of the axis of said first motor and said second motor is in the same plane.
In preferred embodiment of the present invention, the angle of line is α between the said mower moving direction and first motor, second motor, 60 °≤α≤90 °.
In preferred embodiment of the present invention; Said first blade is in and is formed with first spiral case in the housing; Said second blade is in and is formed with second spiral case in the housing, and the outlet of the outlet of said first spiral case and second spiral case merges the formation grass outlet, and said grass outlet one end is connected with the careless case of collection.
In preferred embodiment of the present invention, said first motor and said second motor adopt DC power supply.
Double blade mowing-apparatus of the present invention uses first blade and second blade to mow simultaneously, significantly reduces the mowing electric current, reduces institute's wasted work rate, prolongs the single service time of dc-battery bag, and under identical battery capacity, the mowing time is longer, and the mowing area is bigger; Reduce vibration and noise, under the identical swath condition, the radius of turn of blade, the vibration of blade and noise also can reduce the radius of turn of two blades during use less than single; Owing to lowered use power and vibration, noise; Overcome single blade mowing-apparatus swath when big since radius of turn big need more high-power; The problem of noise and vibration exceeding the standard, under equal-wattage, vibration, the noise conditions, the double blade mowing-apparatus can be realized bigger swath.

Wherein: 1, housing, 2, first motor, 3, second motor, 4, fan blade, 5, first blade, 6, second blade, 7, pressing plate, 8, locking nut, 9, grass outlet, 10, collect careless case, 11, first spiral case, 12, second spiral case.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Like Fig. 1, Fig. 3, a kind of double blade mowing-apparatus shown in Figure 4; Comprise housing 1; At least be provided with first motor 2 and second motor 3 in the housing 1, the output shaft of said first motor 2 is provided with first blade 5, and the output shaft of said second motor 3 is provided with second blade 6; Said first blade 5 is provided with before and after staggering in housing 1 with said second blade 6, and first blade 5 and second blade 6 are along the upright projection of mower moving direction partial stack at least.Guaranteed not have the mowing clear area between first blade 5 and second blade 6; Both maximized and improved the mowing area; Can also prevent that the grass between first blade 5 and second blade 6 from being cut by leakage, significantly improve mowing efficient, reduce the vibration and the noise of whole mower; And significantly reduced the use power of motor, reached object of energy saving.
Said first blade 5 is positioned on the same plane with said second blade 6, and the height that the quilt that through this setting is is mowed is consistent.
Be respectively arranged with fan blade 4 between said first blade 5 and first motor 2, said second blade 6 and second motor 3; First blade 5 and second blade, 6 belows are provided with pressing plate 7; Pressing plate 7 is fixedly connected with fan blade 4 through locking nut 8, cools off through 4 pairs of powerful motors of fan blade.
Said first motor 2 is opposite with the rotation direction of said second motor 3, has improved the careless efficient of going out of grass outlet, and grass outlet is not easy to stop up.
Also be provided with the 3rd motor in the said housing 1, said first motor 2, said second motor 3 and the 3rd motor are the triangle setting.
The axis of the axis of said first motor 2 and said second motor 3 is in the same plane.
The angle of line is α between the mower moving direction and first motor 2, second motor 3,60 °≤α≤90 °.When being 75 ° like α, this setting had both kept the compactedness of whole mower, and the area that has also kept quilt to be mowed is unaffected basically, improves mowing efficient.
Be in and be formed with first spiral case 11 in the housing 1 like Fig. 1, said first blade 5 of Fig. 2; Said second blade 6 is in and is formed with second spiral case 12 in the housing 1; The outlet of the outlet of said first spiral case 11 and second spiral case 12 merges formation grass outlet 9; Increase the sectional area of grass outlet 9, improved the efficient that grass.Said grass outlet 9 one ends are connected with the weeds that the careless case of collection 10, the first blades 5, second blade 6 cut down and get into the careless case 10 of collection through grass outlet 9, can weeds be collected twice laid.
Said first motor 2 adopts DC power supply with said second motor 3.
Double blade mowing-apparatus of the present invention is compared with the single blade mowing-apparatus, and following advantage is arranged:
1, significantly reduce the mowing electric current, reduce institute's wasted work rate, prolong the single service time of dc-battery bag, under identical battery capacity, the mowing time is longer, and the mowing area is bigger;
2, reduce vibration and noise, under the identical swath condition, the radius of turn of blade, the vibration of blade and noise also can reduce the radius of turn of two blades during use less than single;
3, be provided with fan blade 4 between motor and the blade, cool off through 4 pairs of powerful motors of fan blade, make the motor running safer, efficient is higher;
4, improved the swath scope that the type mowing-apparatus can be realized that pushes away; Owing to lowered use power and vibration, noise; Overcome single blade mower swath when big since radius of turn big need more high-power; The problem of noise and vibration exceeding the standard, under equal-wattage, vibration, the noise conditions, the double blade mowing-apparatus can be realized bigger swath.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
