Description
Technical field
the utility model relates to a kind of mower, and the speed reducing pulley upper end particularly relating to a kind of mower is provided with the structure of aerofoil fan, effective mower.
Background technology
mower is widely used in urban afforestation and park and garden design, and using more is pruning to lawn, and it generally comprises five parts: engine, running gear, blade, handrail and control section.Its operation principle is roughly: on the output shaft of engine, blade is housed, blade, by High Rotation Speed after driven by engine, is pruned lawn.
the Chinese patent being CN 102084754 A as publication number discloses a kind of mower, comprising: housing; Be connected to the motor on housing, described motor has motor shaft; For the blade of mowing, described blade is connected on described motor shaft, and has at least one cutting edge; Power supplying apparatus, described power supplying apparatus is electric machine with energy when mower works, thus drives blade to rotate with a cutting speed; Speed control unit, is selectablely fixed at least one pre-set constant rotating speed by described cutting speed.
the rotating speed of the cutting blade of general mower is usually between 3000-4000 turns, and this speed has very excellent cutting effect.Therefore mower time farm labourer do, often motor and belt temperature higher, owing to being subject to the restriction of volume, the inside of existing mower does not often have good radiator structure, and radiating effect is bad, thus has a strong impact on the life-span of belt and motor.At present, the deceleration belt pulley in conventional mower can only transferring power, drives blade to rotate, therefore needs to improve existing structure, increase the radiator structure of mower inside.
therefore, can improve the structure of the belt wheel of motor, improve the radiator structure of mower, volume, cost can not be increased again.
Utility model content
in order to solve the problem, the utility model object is: the mower providing a kind of motor and belt good heat dissipation effect.The speed reducing pulley transferring power on the one hand of this mower, upper end is provided with the structure of aerofoil fan on the other hand, assists motor exhausting, airflow circulating is circulated, plays the effect of cooling motor and belt.
the technical solution of the utility model is: a kind of mower, comprises motor, and described motor is arranged on mount pad, and described motor is by belt drives belt wheel, and belt wheel lower end is fixed with blade, and described belt wheel is provided with axial flow fan structure.
further, described axial flow fan structure is arranged in belt wheel, and one-body molded with belt wheel.
further, the flabellum of described axial flow fan structure is arc.
further, the upper surface of described flabellum is higher than the wheel rim of belt wheel.
further, described flabellum is 6.
further, the lower end of described belt wheel and motor is arranged in the closed cavity of mount pad, and described closed cavity lower end is provided with through hole.
further, described closed cavity is made up of mount pad, and the upper end of described closed cavity is provided with motor installing hole, and lower end is provided with belt wheel installing hole, described through hole is arranged on belt wheel installing hole periphery, and described belt wheel is arranged in installing hole by upper bearing (metal) and lower bearing.
compared to prior art, the utility model has the advantages that:
1, the upper end of the speed reducing pulley of this mower is provided with the structure of aerofoil fan, on the one hand can transferring power, driving blade rotates, assist motor exhausting on the other hand, airflow circulating is circulated, plays the effect of cooling motor and belt, improve the output performance of motor, extend the service life of motor, indirectly reduce cost.
2, because radiator structure is arranged on belt wheel inside, the volume of increase mower that therefore can not be too much, due to axial flow fan structure and belt wheel one-body molded, cost is also not too high.The flabellum of aerofoil fan is arc and higher than the wheel rim of belt wheel, makes better heat-radiation effect.

Embodiment
due to mower time farm labourer do, often motor and belt temperature higher, owing to being subject to the restriction of volume, the inside of existing mower does not often have good radiator structure, and radiating effect is bad, thus has a strong impact on the life-span of belt and motor.At present, the deceleration belt pulley in conventional mower can only transferring power, drives blade to rotate, therefore needs to improve existing structure, increase the radiator structure of mower inside.
therefore, can improve the structure of the belt wheel of motor, improve the radiator structure of mower, volume, cost can not be increased again.
for making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
embodiment:
as shown in Figure 1, a kind of mower of the present embodiment, motor 1 is arranged on mount pad 5, side, mount pad 5 upper surface is provided with motor installing hole, lower surface opposite side is provided with the installing hole 8 for installing belt wheel 3, motor 1 lower end and belt wheel 3 upper end are arranged in a closed cavity 9 being made up of mount pad 5, belt wheel 3 connects the rotating shaft of motor 1 by belt 2, belt wheel 2 is arranged in installing hole 8 by upper bearing (metal) 4 and lower bearing 6 two bearings, blade 7 is fixed by screws in axle portion, belt wheel 3 lower end, and installing hole 8 periphery is provided with the through hole 14 for dispelling the heat.
belt wheel 3 is provided with axial flow fan structure 10, and axial flow fan structure 10 is arranged in belt wheel 3, and one-body molded with belt wheel 3.As shown in Figure 2, the flabellum 13 of axial flow fan structure is arc to the structure of belt wheel 3, and the upper surface of flabellum 13 is higher than the wheel rim of belt wheel 3, flabellum is preferably 6, make like this to design the requirement meeting air-flow, air flow energy is flowed smoothly, thus cooling effect is better.
the wheel rim of belt wheel 3 periphery is provided with belt grooves 11, and the lower end of belt wheel 3 is provided with axle portion, and blade 7 is fixed by screws in axle portion.
the air flow direction of motor internal as shown in Figure 3, wherein the direction of arrow represents air flow direction, because the axial flow fan structure 10 of belt wheel 3 has draft effect, cold wind enters from the upper cover air inlet 12 of motor 1, then enter in closed cavity 9 by stator winding, enter from the axial flow fan structure 10 of belt wheel 3 again, be discharged to outside mower finally by through hole 14, like this, cold air-flow enters from the upper cover air inlet 12 of motor 1 again, the air-flow of heat is discharged to outside mower by through hole 14, and air-flow iterative cycles like this, reaches the cooling effect to motor and belt.
because radiator structure is arranged on belt wheel inside, the volume of increase mower that therefore can not be too much, due to axial flow fan structure and belt wheel one-body molded, cost is also not too high.
structure is simple, with low cost, has good application prospect.
should be understood that, above-mentioned embodiment of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
