Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Embodiment 1, as shown in fig. 1, fig. 2, a dust unloader, wherein, including powder pouring frame 1, powder pipeline 2 and loose stirring portion down, powder pouring frame 1 is connected with powder pipeline 2 down through oblique lower face 3, oblique lower face 3 is top-down, the inclined plane of extending in opposite directions, powder pipeline 2 is for connecting the vertical siphunculus of oblique lower face 3 down, loose stirring portion includes electronic pivot, set collar circle and stirring fan blade 4, the height of electronic pivot flushes with the lower limb of oblique lower face 3, the set collar circle is the ring cover in electronic epaxial drum, stirring fan blade 4 is the extension board of circumference interval arrangement in set collar circle surface. Powder pouring frame 1 is used for collecting the dust, pours into powder pouring frame 1 back into when the dust, and the dust that is located the downside can slide into powder pipeline 2 down along 3 below oblique, gets into in the required article of accomodating through powder pipeline 2 down. However, because the dust can appear piling up and the circumstances of caking appears in the unloading in-process, be unfavorable for the unloading of dust, so need loose stirring portion to prevent that the dust from hardening caking from appearing, specifically, the external motor of electronic pivot, through rotating the cover ring rotation of driving ring cover on surface, at this moment, stirring fan blade 4 also can be along with rotating, in stirring fan blade 4's rotation process, can scrape and bulldoze the dust that contacts, plays loose dust and prevents the effect of caking.

The stirring fan blade 4 is also provided with a bending fan blade 5, and the bending fan blade 5 is connected to the outer end edge of the stirring fan blade 4 through a hinge shaft. The turning fan blades 5 can be straight panels or arc panels and are connected to the edges of the outer ends of the stirring fan blades 4 through hinge shafts, wherein the hinge joints can be provided with torsion springs, so that when external force acts, the turning fan blades 5 can rotate around the hinge shafts, and the initial extending direction can be restored when no external force acts. Namely, along with the rotation, the bent fan blades 5 can be abutted against the inclined lower surface 3 or the wall surface of the powder feeding pipeline 2, at the moment, the bent fan blades 5 can rotate through the hinge shaft until the bent fan blades are not extruded by the wall surface of the powder feeding pipeline 2 and return to the initial state, and the dust can be contacted and swept in a wider range.

As shown in fig. 2 and 3, the stirring blades 4 and the turning blades 5 are further provided with hollowed-out through holes 6 for reducing stirring resistance. The hollow through holes 6 are circular through holes arranged at intervals along the extending direction of the stirring fan blades 4 and the bending fan blades 5. The hollow through holes 6 reduce the rotation resistance of the stirring fan blades 4 and the bending fan blades 5, and meanwhile, dust falling from the upper side to the lower side can directly fall through the hollow through holes instead of being extruded on the surfaces of the stirring fan blades 4 or the bending fan blades 5, so that the possibility of the fan blades being damaged too fast due to extrusion is reduced. The smooth passing surface 7 is also arranged on the hollow through hole 6, and the smooth passing surface 7 is an arc ring surface which is bent, radiated and extended from the wall surface of the hollow through hole 6 to the edge surface of the through hole. The smooth passing surface 7 is more beneficial for dust to enter the hollow through holes 6 from the edges of the hollow through holes 6.

As shown in fig. 4, 5 and 6, the blade further includes a bent interference portion for reducing the surface wear of the blades 5. The bending collision part comprises a fan blade groove 8 and a pipe end collision particle 9, the fan blade groove 8 is an arc-shaped groove which extends from the middle part of the outer end edge of the bending fan blade 5 to the middle part of the hinge shaft and has a semicircular cross section, and the pipe end collision particle 9 is a spherical particle which protrudes outwards from the middle part of the upper edge of the powder feeding pipeline 2. When the turn flabellum 5 contradicts to 3 lower limb of below or powder pipeline 2 upper edge down along with rotating, the accessible is buckled conflict portion and is realized contact between them, when turn flabellum 5 is close to gradually promptly, the mode of conflict grain 9 embedding flabellum recess 8 through the pipe end realizes conflicting the turn of turn flabellum 5, avoid turn flabellum 5 to be slided and excessively wearing and tearing by the conflict of large tracts of land, meanwhile, turn flabellum 5 diminishes with the area of contact of 3 of below 3 to one side, can prevent that the caking condition of dust from appearing between the area of contact, make the lower limb of below 3 or the upper edge of unloading pipeline appear the condition that the dust caked because of turn flabellum 5 conflicts no longer. Particularly, due to the existence of the smooth passing surface 7, when the pipe end collision particles 9 move in the fan blade groove 8, the special knocking feeling can not occur when the pipe end collision particles pass through the edge of the hollow through hole 6.

The pipe end abutting particles 9 are provided with inclined holes which are through holes consistent with the inclined direction of the inclined lower surface 3. The setting of slant hole prevents that the dust from conflicting the oblique top side formation of grain 9 at the pipe end and piling up or agglomerating, and the lower limb in slant hole flushes with the surface of oblique lower surface 3, can make things convenient for the gliding of dust to pass through.

And also includes a slot end projection 10 for protecting the edge of the bent vane 5. The groove end protrusion 10 is an arc-shaped panel which is bent outwards from the groove surface at the outer end of the fan blade groove 8 and extends to the outer side of the fan blade groove 8. The groove end protrusion 10 can vibrate to remove residual dust when the turning fan blade 5 is separated from the pipe end abutting particles 9, and can also provide a contact part for the turning fan blade 5 to abut and slide on the wall surface of the powder discharge pipeline 2, so that abrasion of the turning fan blade 5 is avoided.
