Abstract
The invention provides an impeller with large exhaust air rate and capable of forming an air pump with a housing of an air cushion type lawn mower. The impeller with large exhaust air rate created by the invention consists of a ring-shaped baseplate, a hub and more than 16 blades. The air cushion type lawn mower adopting the impeller with large exhaust air rate structurally comprises the housing, the impeller, a gasoline engine, a woodruff key, a connecting sleeve, a mowing knife, a hand pushing handle and a throttle controller. The air cushion type lawn mower created by the invention is suitable for mowing in sloping fields.
Description
Technical field
The invention relates to air cushion type hay mower technical field, is specifically related to a kind of large exhaust air rate impeller and uses the air cushion type hay mower of this impeller.
Background technique
Along with China's rapid development of economy, people's environmental consciousness strengthens day by day, and green lawn has become fashion, and China's green grassland area is just with annual 25% speed increment, and turf-mown machinery market is very large.Widely used common hand-pushing (self-propelled type) hay mower has occupied more than 70% market both at home and abroad at present, but this product can not be realized slope mowing, and minimum mowing height higher (25mm), can not meet the demand on refine lawn.When people are during to turf-mown quality requirement higher (as golf course etc.), common lawn mowing machine often can not meet user's request.
Summary of the invention
For coordinating air cushion type hay mower to adapt to hillside fields, use, the invention provides a kind of can form with the shell of air cushion type hay mower the large exhaust air rate impeller of air pump.
Large exhaust air rate impeller described in the invention is comprised of ring base plate, wheel hub and 16 above blades, and the inner side of ring base plate and the outside of wheel hub are fixed together, blade camber, be fixed on wheel hub and ring base plate above; Its one end originates in wheel hub outer rim, and the blade end on wheel hub is blade inlet, and the blade end on ring base plate is blade exit; Blade inlet established angle β
1Abe 46 °～57 ° (preferably 51 °); Blade exit established angle β
2Awith flow angle β
2inconsistent, blade exit established angle β
2Abe 36 °～44 ° (preferably 40 °).
Adopt larger β
1Aangle, although shock at entry loss increases, the flow losses of Ye Daonei reduce, efficiency improves on the contrary.
Blade exit established angle β
2Awith flow angle β
2inconsistent, can to produce axial eddy effect.
The diameter of described large exhaust air rate impeller is 350mm～420mm, and larger impeller diameter can form high velocity air.The height of the blade of described large exhaust air rate impeller is 36mm～44mm, and higher blade can increase the circumferential resistance of air-flow, thereby increases the tangential mobilization dynamic of air-flow.
As preferably: the diameter of described large exhaust air rate impeller is 380mm.The height of the blade of described large exhaust air rate impeller is 40mm.
The blade of described large exhaust air rate impeller be uniformly distributed with impeller on, for improving impeller pressure, reduce the impact of relative eddy.
The structure of the air cushion type hay mower of the above-mentioned large exhaust air rate impeller of use described in the invention comprises: housing, impeller, petrol engine, woodruff key, connecting sleeve, hay knife, hand-pushing handle, throttle control.Housing is the pedestal of mowing machine, and petrol engine and hand-pushing handle are fixed on housing; Impeller is connected with the output shaft of petrol engine by connecting sleeve, half dollar key; Hay knife is connected in petrol engine main shaft.The central authorities of housing upper end are provided with air inlet, and the surrounding of housing lower end is provided with air outlet slit.
When petrol engine rotates, impeller and housing form air pump, and air enters from housing upper end central authorities, from housing lower end surrounding, discharge, and utilize like this aerostatic buoyancy that housing is lifted machine is suspended on lawn; During petrol engine rotation simultaneously, hay knife also rotates, thus cutting lawns.When manually promoting hand-pushing handle gently, machine is suspended on lawn and moves, thus continuous cutting lawns.
Regulate throttle control can regulate petrol engine rotational speed height, improve mowing efficiency.
Air cushion type hay mower described in the invention, its impeller and housing form air pump, when petrol engine High Rotation Speed, impeller rotation, in housing, produce vacuum, air is from the suction suitable for reading of machine central authorities, and the ejection downwards of the outlet port of air pump is with the air of certain pressure, thereby machine is lifted and built on stilts, guarantee operator easily advance mowing machine before so that mow.
