Multiple first through hole 9.
The aperture of first through hole 9For 3mm~9mm.As shown in fig. 6, the pitch of holes L2 between two neighboring first through hole 9
For 20mm~40mm.Aperture is too big or pitch of holes is too small, and too big impact force may be caused to material, influences the normal of material
Rotation and acceleration;Aperture is too small or pitch of holes is too big, then possibly can not form enough air films, to cannot achieve reduction abrasion
Effect.
Multiple rows of being arranged circumferentially along first annular shell 7 of first through hole 9.Center between adjacent two rows first through hole 9
Angle γ 1 is 5 °~10 °.Hole row setting get Tai Mi, may will increase difficulty of processing;Hole row is arranged too dilute, it is likely that can not
Air film is formed, preferable abrasionproof effect is unable to reach.
The line of centres that often ranked first multiple first through hole 9 in through-hole 9 is parallel with the axis of first annular shell 7.
First shell is annulus along axial section, and peripheral side (i.e. the first ring of first shell is arranged in first through hole 9
On shape shell 7), normal slope of the axis of first through hole 9 relative to first shell at first through hole 9.The benefit being arranged in this way
It is the diametrical direction inclination that can make to enter the intracorporal airflow direction of first shell by first through hole 9 relative to first shell
Direction, avoid air-flow from directly blowing to material along the direction parallel with diametrical direction, influence the rotation speed of material.
The axis and first shell of first through hole 9 are at first through hole 9 along the tangential direction of the direction of rotation of rotating mechanism
Between angle be acute angle.Setting can make to enter by first through hole 9 the intracorporal air-flow of first shell and rotating mechanism in this way
Direction of rotation is roughly the same, avoids increasing material rotational resistance, influences material rotation speed.

Equipped with multiple ventilation holes.
Scattering mechanism further includes wearing plate 10, and wearing plate 10 is arranged in the inside of first shell, wearing plate 10 be used for from
The air-flow that first through hole 9 flows into inside first shell is oriented to.By setting wearing plate 10, air-flow can be oriented to,
It prevents air-flow from causing to impact to material, influences material rotation speed;First shell can also be enhanced to the abrasive resistance of material, prolonged
The service life of long first shell.Wearing layer can be set in the side of the separate first shell of wearing plate 10, enhances abrasion-resistance.
As shown in fig. 7, wearing plate 10 is obliquely installed relative to the inner wall of first shell.Setting is convenient for leading air-flow in this way
To, while can be to avoid the revolution space for occupying too many material.
Optionally, wearing plate 10 is mutually flat relative to the inclined direction of the inner wall of first shell and the axis of first through hole 9
Row can not only prevent air-flow from directly impacting wearing plate 10 in this way, but also can keep air-flow in first shell by wearing plate 10
Circulating direction.
Wearing plate 10 often ranked first the leeward of through-hole 9 along being axially disposed within for first shell, i.e. the axis of first through hole 9
With the biggish side of inner wall angle of first annular shell 7, wearing plate 10 is located at the upper of the material direction of rotation that often ranked first through-hole 9
Trip.It often ranked first the corresponding wearing plate 10 of through-hole 9, so as to can be directed to by the air-flow that often ranked first through-hole 9.Wearing plate
The 10 neighbouring through-holes 9 that often ranked first are arranged, and can also be improved guide effect.

1, it is equipped with including inside and outside double Shell, and on inner and outer shell through-hole, when scattering mechanism works, ambient atmos can lead to
The inside that through-hole enters inner shell is crossed, the air film of isolation material and shell is formed in the inside of inner shell, reduces to shell
Abrasion, while the resistance to material can also be reduced, reduce the speed loss to material in accelerator, speed is shed in raising
Degree;
2, the axis of first through hole set in first shell is arranged relative to normal slope at this, can be to avoid to object
Material causes resistance, is also beneficial to form air film;
3, the side that often ranked first through-hole is equipped with wearing plate and carries out water conservancy diversion, in addition to preventing air-flow from making to the rotation speed of material
Except influence, protection first shell can also be played the role of, reduce the abrasion to first shell;
4, the baffle that is circumferentially with of blade forms accommodating chamber, streamlined material lining can be formed on the head of blade, by leaf
Piece and material completely cut off, and blade is prevented to be worn, and improve the service life of blade, and the streamlined material lining of formation also can reduce pair
The resistance of material improves the dispensing velocity of material;
5, blade is obliquely installed relative to the plane vertical with impeller rotating shaft line, the baffle of blade body side relative to
Blade body is obliquely installed, and is conducive to take up more materials in this way, and can form streamlined material lining, and material and leaf is isolated
Piece reduces the abrasion to blade.
Scattering mechanism embodiment of the present invention can not only reduce the abrasion to shell, but also can reduce the abrasion to blade, throw
The whole service life for spreading device is longer, and maintenance cost is low.
Based on above-mentioned scattering mechanism, the present invention also proposes a kind of material scattering machine, which includes above-mentioned
Scattering mechanism.Scattering mechanism in above-mentioned each embodiment can be used as centrifugal blower, be used for material scattering machine, realize to object
Material is shed.Material can be solid particle etc..
Positive technical effect possessed by scattering mechanism is equally applicable to material scattering machine in above-mentioned each embodiment, here
It repeats no more.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof;To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced, for example change blade
Quantity, wearing plate form, the arrangement circle number of first through hole and wearing plate, quantity, size, tilt angle etc.;Without departing from this
The spirit of inventive technique scheme should all cover within the scope of the technical scheme claimed by the invention.
