Abstract
The invention relates to a tubular fan impeller used for a leaf cutter, and the impeller is composed of a blade, a side central disk, a central disk, a middle central disk, a shaft, a shaft sleeve, a steel wire and a steel wire fastening regulating device. Good wind current is formed in a fan volute so as to effectively blow out broken leaves.
Description
Technical field
The invention belongs to a kind of leaf-shearing machine cross flow fan impeller, particularly the cross flow fan blade wheel structure changes, and the versatility that belongs to cross flow fan is used.
Background technique
At present, the leaf-cutting device of disclosed a kind of leaf-shearing machine on the market, be that the leaf-cutting device is installed on the frame of leaf-shearing machine, back at the leaf-cutting device is provided with wind wheel, and the wind wheel back is provided with broken leaf collecting box, but this leaf-cutting device volume is big, shearing blade that can not be in full force and effect, broken leaf can't be blown into collecting box fully, broken leaf is residual many, and is big to the harm of growing seedlings.
And cross flow fan is straight and evenly meet people to comfortable requirement with the wind that blows out, and is extensively applied to low pressure ventilation ventilation occasions such as domestic air conditioner, and agricultural material such as please select at the aspect.The most dihedral vanes that adopt of existing cross flow fan, each blade is at the vertical central shaft several angle that turns forward relatively, and impeller in the inner passage turbulent flow that forms of spiral case, produces static pressure at work, forms air-flow stably in the snail tongue room.But broken leaf can appear in the impeller of blade FC in the application of leaf-shearing machine blows inadequately, has more broken leaf residual in impeller, is not suitable for leaf-shearing machine and uses.
Summary of the invention
Problem to be solved by this invention is, a kind of leaf-shearing machine cross flow fan impeller is provided, in volute of blower, form distinguished and admirable preferably, the effective leaf-shearing machine impeller that broken leaf is blowed away.
For achieving the above object, leaf-shearing machine of the present invention designs with the work characteristics combination of cross flow fan impeller according to cross flow fan impeller and steel wire (or steel blade) leaf-cutting.Leaf-shearing machine of the present invention is made up of blade, limit mid-game, mid-game, mid-game, axle, axle sleeve, steel wire (or steel blade), steel wire (or steel blade) fastening adjustment device with the cross flow fan impeller.The multi-disc blade is fixed in limit mid-game, mid-game, the mid-game at the vertical relatively central shaft several angle that recedes, the center hole of the band lug at limit mid-game, mid-game, mid-game middle part connects with the axle sleeve of band groove, dual-side mid-game central position is fastened with axle sleeve, and axle sleeve is fastened on the axle with screw; Be equipped with on limit mid-game and limit, mid-game outer steel wire (or steel blade) fixed position is installed, steel wire (or steel blade) fastening adjustment device is installed on limit, dual-side mid-game outer.
Compared with prior art, characteristics of the present invention are:
1, blade is at the vertical relatively central shaft several angle that recedes, and forms stronger static pressure in that spiral case is inner in the work, reaches steadily powerful distinguished and admirable;
2, leaf-cutting steel wire (or steel blade) and the coaxial work of wind wheel make the broken leaf sheared down can very fast the blowing away of quilt, and it is residual to significantly reduce broken leaf;
3, settle the fastening adjustment device of steel wire (or steel blade) in the mid-game of impeller limit, be convenient to steel wire adjusting is installed, easy to use;
4, adopt combining of cross flow fan impeller and leaf-cutting device, the volume of attenuating leaf-cutting mechanism is raised the efficiency easy maintenance.
Description of drawings
The present invention is described further below in conjunction with drawings and embodiments

Fig. 2 is impeller mid-game figure;
Fig. 3 is an impeller shaft.
Among the figure: 1, the fastening adjustment device 3 of axle sleeve 2, steel wire (or steel blade), steel wire (or steel blade) 4, blade 5, axle 6, limit mid-game and mid-game 7, mid-game.
Embodiment
Below in conjunction with the drawings and specific embodiments a kind of leaf-shearing machine of the present invention is further described with the cross flow fan impeller.
Fig. 1, Fig. 2, leaf-shearing machine of the present invention shown in Figure 3 are made up of blade 4, limit mid-game 6, mid-game 7, mid-game 6, axle 5, axle sleeve 1, steel wire (or steel blade) 3, steel wire (or steel blade) fastening adjustment device 2 with the cross flow fan impeller.Multi-disc blade 4 is fixed in limit mid-game 6, mid-game 7, the mid-game 6 at vertical relatively central shaft 5 several angle that recedes, the center hole of the band lug at limit mid-game 6, mid-game 7, mid-game 6 middle parts and axle 5 sockets of being with groove, dual-side mid-game 6 central positions are fastened with axle sleeve 1, and axle sleeve 1 usefulness screw is fastened on the axle 5; Be equipped with on limit mid-game 6 and limit, mid-game 6 outer steel wire (or steel blade) 3 fixed positions are installed, steel wire (or steel blade) 3 fastening adjustment devices are installed on limit, dual-side mid-game 6 outer.
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
Claims (2)
1. leaf-shearing machine cross flow fan impeller, comprise blade 4, limit mid-game 6, mid-game 7, mid-game 6, axle 5, axle sleeve 1, steel wire 3, steel wire fastening adjustment device 2 compositions, it is characterized in that: described multi-disc blade 4 is fixed in limit mid-game 6, mid-game 7, the mid-game 6 at vertical relatively central shaft 5 several angle that recedes, the center hole of the band lug at limit mid-game 6, mid-game 7, mid-game 6 middle parts and axle 5 sockets of being with groove, dual-side mid-game 6 central positions are fastened with axle sleeve 1, and axle sleeve 1 usefulness screw is fastened on the axle 5; Be equipped with on limit mid-game 6 and limit, mid-game 6 outer steel wire 3 fixed positions are installed, steel wire fastening adjustment device 2 is installed on limit, dual-side mid-game 6 outer.
