Abstract

A hay mower blade comprises a blade body, wherein the blade body comprises a center installation portion and two end portions extending outwards from the two opposite sides of the center installation portion. One side of each end portion is provided with a cutting edge, and the opposite side of each end portion is provided with a fan portion. The hay mower blade is characterized in that each end portion further comprises a solid area B and a cutting area C, and the projected area ratio of the solid area B and the cutting area C on an installation plane is 3:7 to 7:3. The hay mower blade is simple in structure, easy to achieve, and capable of effectively reducing influence of unnecessary blade structures, effectively reducing output power of power work elements, and achieving the purpose of saving electric energy.

Description

A kind of mower blade
Technical field
The utility model relates to a kind of mower blade, especially a kind of for the blade on hay mower.
Background technology
At present, mower has been widely used in the lawn care field for lawn care, and wherein the blade for mower is generally strip, and the centre of blade arranges installing hole, at the strip blade, near the avris of end position, is provided with two cutting edges.
Yet most mower blades are often focused on low cost, processing is simple, and to mower blade, the energy consumption problem when working is not paid close attention to and improves.Especially direct current mower, often much electricity is wasted in unnecessary in-fighting and load, has reduced the operating efficiency of mower.Equally, even if use the mower of fuel, also exist energy consumption problem, also can bring extra environmental pollution simultaneously.
Summary of the invention
The utility model provides a kind of technical scheme in order to solve the problems of the technologies described above:
A kind of mower blade, comprise cutter hub, described cutter hub comprises central installation portion and stretches out along the relative both sides of described central installation portion and two ends forming, one side of each end is provided with blade, relative another side is provided with fan portion, it is characterized in that: described end also comprises entity area B and cut-away area C, and entity area B and the cut-away area C projected area ratio on mounting plane is 3:7~7:3.
Preferably, described fan portion outer end is less than 80% to the ratio of the width dimensions h between blade and blade width size H.
Preferably, the formed angle of described fan and blade is less than 45 °.
Preferably, described fan blade is bending shape.
Preferably, the central installation portion of described mower blade directly is connected with the output shaft of mower.
Preferably, also there is a depressed part between the central installation portion of described mower blade and fan portion.
The structure of the cutter hub of this mower blade arranges simply, is easy to realize, effectively reduce the impact that unnecessary blade structure brings simultaneously, can very effectively reduce the power output of dynamically working element, thereby reach the purpose of saving electric energy, especially make the power brick energy of direct current mower can more be applied to cutting operation.
The accompanying drawing explanation
Fig. 1 is the structural representation of mower and blade in the utility model embodiment; Fig. 2 is the floor map of mower blade in the utility model embodiment; Fig. 3 is the local enlarged diagram in the end of mower blade in the utility model embodiment; Fig. 4 is mechanical output that in the utility model embodiment, mower blade is applied in the direct current mower contrast schematic diagram about the shared end of entity area B ratio; Fig. 5 is that in the utility model embodiment, mower blade is applied in the direct current mower power brick idle time is about the contrast schematic diagram of the shared end of entity area B ratio.
Embodiment
Below in conjunction with drawings and Examples, further the utility model is illustrated:
As shown in Figures 1 to 3, a kind of mower blade, comprise cutter hub 2, cutter hub 2 has central installation portion 10 and stretches out along the relative both sides of described central installation portion and two ends 21,22 of forming, each Tiao limit, end is provided with blade 24, relative another side is provided with fan portion 23, and end comprises entity area B and cut-away area C, and entity area B and the cut-away area C projected area ratio on mounting plane is 3:7~7:3.If area is less than 3:7, the intensity of fan portion 22 can be very poor, and the difficult processing of flabellum bending.
Width dimensions between fan portion 23 outer end fan blades 25 and blade 24 horizontal plane of living in is h, with the ratio of blade width size H, is less than 80%.Simultaneously, the extended line institute shape of fan portion 22 and blade 24 is α in an angle, and this angle setting is less than 45 °.
The central installation portion of mower blade directly is connected with the output shaft of mower, and is matched in clearance between the two.Also have a depressed part between the central installation portion of mower blade and fan portion, this is convenient to cutter hub 2 is fixed on output shaft by bolt 11.
As shown in Figure 4, embodiment by this to this blade is tested, under the prerequisite that realizes identical performance (air quantity), constantly change the proportionate relationship between entity area B and cut-away area C, by change entity area B in end (entity area B and cut-away area C area sum) proportion, can realize the change of corresponding machine power.The shared ratio of entity area B is higher, and the power of machine increases along with the increase of entity area B proportion.When the ratio of entity area B and end area (entity area B and cut-away area C area sum) is greater than 30%, needed power when the power of machine meets the machine cutting.When the ratio of entity area B and end area (entity area B and cut-away area C area sum) is less than 30%, the intensity of fan portion 22 can be very poor, and the difficult processing of flabellum bending, in fact is difficult to application.
As shown in Figure 5, under the prerequisite of same battery containing amount, entity area B in end (entity area B and cut-away area C area sum) proportion is on certain impact is arranged discharge time, along with the increase of entity area B proportion, constantly reduce the idle time of power brick.When the ratio of entity area B and end area (entity area B and cut-away area C area sum) is less than 70%, be greater than 37 minutes the idle time of machine, can meet the demand of user to the power brick working time, and when the ratio of entity area B and end area (entity area B and cut-away area C area sum) is greater than 70%, the idle time of machine can be shorter and shorter, can not meet the demand of user to the operating time.In sum, entity area B and end area (entity area B and cut-away area C area sum) are while being 30%~70%, could meet the demand of user to machine cutting power and working time simultaneously, thereby reach the purpose of saving electric energy, especially make the power brick energy of direct current mower can more be applied to cutting operation.
