Opening 112 is interconnected by interconnecting part 113, therefore projection material from the 1st rectangular aperture 110 to the 2nd square
Discharged continuously in the range of shape opening 112.
In the projection distribution of the projection material projected by projection machine 18, the part that multiple projection ratios are higher
(peak value) is synthesized, its result, and the scope that projection ratio is higher is continuous.
And, the blade 78 in present embodiment is formed with receding section 90.Therefore, first arrange from orienting cover 64
The opportunity that projection material out contacts with the surface 88 of blade 78 postpones.Thus, the throwing formerly ejected
Penetrate the moment that material contacts with the surface 88 of blade 78, the projection material that thereafter lets out and first ejecting
Projection material comes together in the close proximity on the surface 88 of blade 78.Therefore, projection material is the angle of spread
Spend less fan shape to be projected, between the projection higher part of ratio and the relatively low part of projection ratio
Transition portion is shorter, i.e. be obtained in that the projection that the ascendant trend of the projection distribution curve of projection material is steep
State.
In the projection distribution of the projection material projected by projection machine 18, the part that multiple projection ratios are higher
(peak value) synthesizes, its result, and scope HR that projection ratio is higher becomes in tableland shape continuously
Shape ((A) of Fig. 8).
If by scope HR higher for this projection ratio, it specifically it is scope HR that this projection ratio is higher
Width setup when arriving stirring region W becomes roughly the same with the width of stirring region W, then workpiece stirring
Projection ratio at the central part CP in portion 14 is roughly the same with the projection ratio at left and right end portions EP, and,
Beyond workpiece mixing part 14, the projection material of projection reduces ((B) of Fig. 4).
Therefore, in the shot-blast equipment 10 of present embodiment, to projection machine 18 and workpiece mixing part
The structure of 14, relative configuration etc. are set, so that the position of stirring region W, projection ratio
The scope of the width of higher scope HR is roughly equal with the width of stirring region W.
Then, the action to above-mentioned shot-blast equipment 10 illustrates.
First, input/output port is opened, and utilizes workpiece to put into parts 38 by multiple work piece configuration in workpiece
The pit part 34 (stirring region W) of mixing part 14.
It follows that input/output port is closed, casing 12 becomes closed state.Further, rotating shaft component
20 rotate to arrow R2 direction under the effect driving motor 32, and conveyer belt 26 rotates to arrow R3 direction
(traveling).Thus, the workpiece of stirring region W is stirred by the direct of travel along conveyer belt 26.
And, projection machine 18, bucket elevator 48 and conveying worm 46 work, and projection material is from bucket
Formula elevator 48 puts into pipe 56 and introducing cylinder via separator 50 and hopper 52 and by projection material
54 put into projection machine 18.
Specifically, the projection material by the inside of introducing cylinder 54 is directed to the allotter of projection machine 18
114.Allotter 114 rotates under carrying out the effect of driving force of drive motor 86, and therefore projection material exists
Under the effect of centrifugal force, the outer circumferential side to allotter 114 moves, and the inner peripheral surface along orienting cover 64 moves.
Along the orienting cover 64 shown in Fig. 6 inner peripheral surface movement projection the material opening from orienting cover 64
108 discharge along the direction tilted to direction of rotation (the arrow R direction) front side of impeller 62.Eject
Projection material is in the periphery of orienting cover 64 and rotation under carrying out the effect of driving force of drive motor 86
The blade 78 of impeller 62 contacts.
Specifically, the receding section 90 with the surface 88 of blade 78 contacts.Touch the projection of receding section 90
Material is accelerated under the influence of centrifugal force while moving to non-receding section 91, from the top of blade 78
Portion departs from, thus is projected.Further, as shown in (A), (B) of Fig. 4, by from body shell 60
The lateral workpiece mixing part 14 of following side end 68 stirring region W in workpiece projection, to workpiece implement
Bead.
Project the projection material in workpiece mixing part 14 and the dust produced when bead, broken thing
(rust) etc. discharge to the outside of conveyer belt 26 from the through hole of conveyer belt 26 together.The projection material ejected
Material etc. comes together in the bottom of casing 12, is concentrated on the bottom of bucket elevator 48 by conveying worm 46.So
After, transported to separator 50 by bucket elevator 48, be separated into dust and broken thing and energy by separator 50
The projection material etc. enough re-used.This isolated projection material is accumulated in hopper 52 and via projection material
Material puts into pipe 56 and supplies to projection machine 18 and be easily reused.
When through the scheduled time, when bead completes, the work of projection machine 18 stops, casing 12 defeated
Enter delivery outlet to be opened.It follows that utilize workpiece discharge member by workpiece outside shot-blast equipment 10
Portion exports, a series of end of job.
Then, contrast with the structure (comparative example) shown in Fig. 9, while the spray to present embodiment
Effect and the effect of ball processing means illustrate.Additionally, in comparative example, for this embodiment party
The constituting portion minute mark that formula is identical notes identical reference and the description thereof will be omitted.
In the shot-blast equipment of comparative example, as shown in (A) of Fig. 9, it is located at the interior of projection machine 200
The surface of the direction of rotation front side of the blade 204 of the impeller 202 in portion is from the center of rotation C edge of impeller 202
Radially (RADIAL L3) to extend.
Therefore, the projection material first ejected from the opening 205 of orienting cover 203 and the projection thereafter let out
Material substantially simultaneously contacts with blade 204 in different position radially respectively and is added to top orientation
Speed, departs from from the top of blade 204, thus projects material and be projected.Thus, the throwing formerly ejected
Penetrate between material and the projection material thereafter let out, projection material from the top of blade 204 projection
Opportunity is different, and the projecting direction respectively projecting material is different, projects material from projection machine 200 in expansion
The fan shape that angle is bigger is projected.
It addition, as shown in (B) of Fig. 9, in the projection machine 200 of comparative example, the opening of orienting cover 203
205 is single, therefore as shown in the projection scattergram of (B) of Fig. 8, in the distribution of projection material,
The part (peak value) that projection ratio is higher is also single.
Therefore, the central part CP as shown in (B) middle double dot dash line of Fig. 4, in workpiece mixing part 14
Place's projection ratio becomes many, and at left and right end portions EP, projection ratio tails off.And, conveyer belt 26 is to length direction
(arrow R3 direction) advance, therefore workpiece due to conveyer belt 26 rotation and by the length along conveyer belt 26
The stirring of degree direction, but be difficult to the width along conveyer belt 26 and move.Thus, in workpiece mixing part 14
In central part CP and left and right end portions EP at exist workpiece processing quality produce deviation probability.
In contrast, in the shot-blast equipment 10 of present embodiment, as shown in Figure 6, at impeller 62
The surface of direction of rotation front side of blade 78 be formed relative to radially to direction of rotation (arrow R side
To) rear side tilt receding section 90.Therefore, in the throwing first ejected from the opening 108 of orienting cover 64
Penetrate before material contacts with the surface 88 of blade 78, the throwing thereafter let out from the opening 108 of orienting cover 64
Penetrate material to contact with the surface 88 of blade 78 and be accelerated while moving towards the tip side of blade 78.
In the shot-blast equipment 10 of present embodiment, the projection material first ejected thereafter letting out and
The projection that surface along blade 78 has moved contacts with surface 88 near the position existing for material,
The projection material the most first ejected and the projection material thereafter let out are collected at the surface of blade 78
Close proximity on 88.
Projection material is projected, therefore, it is possible to make projection divide so that the state so summarized departs from blade 78
Cloth is concentrated.That is, the distribution from the projection material of projection machine 18 projection becomes the direction of rotation along impeller 62
The less fan shape of expanded angle.
And, the opening 108 discharging projection material of orienting cover 64 has and includes and the center of orienting cover 64
1st rectangular aperture the 110 and the 2nd rectangular aperture 112 on the both sides that axis CL is parallel, therefore projection material quilt
Discharge from each rectangular aperture 110,112 and interconnecting part 113.It addition, the 1st rectangular aperture 110 and the 2nd
Rectangular aperture 112 is interconnected by interconnecting part 113, and therefore projection material is from the 1st rectangular aperture 110 to the
Discharged continuously in the range of 2 rectangular apertures 112.
Thus, as shown in (A) of Fig. 8, in projection distribution on the whole containing multiple projection ratios relatively
High part (peak value), the scope that projection ratio is higher broadens.
And, the blade 78 in present embodiment is formed with receding section 90, therefore, as mentioned above, it is possible to
Obtain the projection state that the ascendant trend of projection distribution curve is steep.
Further, in the present embodiment, scope HR higher for projection ratio is set to width and stirring
The width of region W is roughly the same, therefore, it is possible to alleviate the work caused because of the position in workpiece mixing part 14
The deviation of the processing quality of part, and the projection material projected beyond workpiece can be made, i.e. to casing 12
Ratio minimizing Deng the projection material of projection.Thus, it is possible to the abrasion of suppression shot-blast equipment 10 self,
It is thus possible to reduce the maintenance frequency of shot-blast equipment 10.
It addition, generally, the bead of the position that the projection ratio of projection material is relatively low with project material
The bead of the higher position of projection ratio compare, the time needed for bead is elongated.
Therefore, the time needed for the bead of projection machine becomes until the projection ratio of projection material is relatively low
The bead to workpiece of position complete till time.Thus, in the present embodiment, logical
Cross the higher position of projection ratio and be set to the scope equal with the width of conveyer belt 26, thus workpiece is deposited
The projection ratio of scope uprise on the whole, therefore, it is possible to shorten until the bead of workpiece is completed
Till time.
And, by being formed with non-receding section 91 in the top ends side of blade 78, projection material is from blade 78
By along non-receding section 91 CENTRIFUGAL ACCELERATING during disengaging.Generally, projection material velocity of projection when being projected by
That work in surface 88 along blade 78, by the blade 78 of the speed in the direction of CENTRIFUGAL ACCELERATING and rotation
The conjunction of both the speed of the tangential direction (hereinafter referred to as " tangential direction ") of the circle that top is described
Speed is become to determine.
When blade hypsokinesis, along the tangential direction component of speed in direction on surface of blade relative to cutting
The speed in line direction works to negative direction.Its result, in rotation external diameter and the rotation circumference speed of blade
Spend identical in the case of, aggregate velocity during blade hypsokinesis does not has aggregate velocity during hypsokinesis low than blade.
As it has been described above, in the shot-blast equipment of present embodiment, projection material is until it will be projected
Non-receding section 91 less with angle of inclination rearward till before contacts, therefore along blade 78
In the velocity component on surface, the tangential direction component worked to negative direction relative to the speed of tangential direction
Less, the degree making aggregate velocity reduce is less.Its result, will not make the rotating speed of impeller increase, and then
The rotating speed that will not be used in the motor that impeller rotates increases, it becomes possible to carry out efficient bead, energy
The reduction of enough suppression projection electrical efficiencies.
And, the radical length of the receding section 90 of impeller 62 is set to longer than the length of non-receding section 91, because of
This can utilize the receding section 90 of blade 78 to collect projection material fully.It is as a result, it is possible to contract further
The weakness reason time.
It addition, be formed on the surface 88 of blade 78, receding section 90 is gently connected with non-receding section 91
Bending section 92, therefore after the receding section 90 utilizing blade collects projection material, it is possible to utilize bending section
92 and non-receding section 91 make the speed of projection material be gradually increased.Thereby, it is possible to it is smooth to project material
Ground projection.
