The specific embodiment

Below, be elaborated at first embodiment that has used shot blasting equipment of the present utility model based on Fig. 1～Fig. 3.This shot blasting equipment possesses as shown in the figure: chamber 1, and it prevents that the shot that is throwed from splashing and is respectively equipped with at right, left side wall that steel plate is moved into mouthful and steel plate is taken out of mouth; As the ribbon conveyer 2 of conveying device, it is provided in the chamber 1, steel plate W is moved into from steel plate mouthful be transported to steel plate and take out of mouth; First roller path 3, it is equipped on the right side of chamber 1, and possesses the roller of rotation type, is used for steel plate W is moved into ribbon conveyer 2; Second roller path 4, it is equipped on the left side of chamber 1, and possesses the roller of rotation type, is used for steel plate W is taken out of from ribbon conveyer 2; The shot grenade instrumentation 5 of centrifugal projection-type, this shot grenade instrumentation 5 is installed on the roof of chamber 1, the steel plate W projection shot on ribbon conveyer 2; Shot EGR 6, it supplies with shots to shot grenade instrumentation 5, and 1 reclaims the shot that has been throwed and make the shot circulation from the chamber.

And, in order to carry steel plate W under the state that with respect to the horizontal plane tilts at steel plate W, the shot that is throwed can be slided from above with required angle, the conveyor surface of the ribbon conveyer 2 and second roller path 4 with respect to the horizontal plane tilts with the angle of 20～60 degree.

In addition, as shown in Figure 2, the outside of 1 left and right sidewall in the chamber is separately installed with and prevents that shot from taking out of mouthful and steel plate is moved into mouthful sealing mechanism 14,15 of the rubber window curtain type that splashes from steel plate.

In addition, as depicted in figs. 1 and 2, shot EGR 6 possesses: chute 7, and it is installed on the bottom of chamber 1; Chain bucket elevator 8, it erects setting and its supply port is communicated with the outlet of chute 7; Separator 9, it is mounted to the mouth of taking out of of chain bucket elevator 8 and is communicated with, and shot is separated with impurity; Hopper 10, the shot outlet that it is installed on separator 9 retains shot temporarily; A plurality of ingress pipes 12, they import shot grenade instrumentation 5 with the shot of hopper 10 across gate 11; Precipitron 13, it is connected with separator 9 with chain bucket elevator 8, is recovered in the dust that produces in the device.

According to aforesaid formation, if under the state that makes first, second roller path 3,4, ribbon conveyer 2, shot grenade instrumentation 5 and 6 work of shot EGR, the steel plate W that treats shot-peening is placed on first roller path 3, and then steel plate W is carried by first roller path 3, ribbon conveyer 2, second roller path 4 successively.And, steel plate W accepts on ribbon conveyer 2 from the shot of shot grenade instrumentation 5 projections, thereby be carried out shot-peening, on the other hand, steel plate W is because of being placed on the ribbon conveyer 2 and second roller path 4, and the shot of the face that therefore is placed on it slides on steel plate W and can not remain on the steel plate W.

In addition, in the present embodiment, ribbon conveyer 2 is inclined relative to horizontal 20 degree, but can be on steel plate W under the little situation in inclination angle residual shot, the big situation lower steel plate W in reverse inclination angle can float in course of conveying or come off from ribbon conveyer 2, so the inclination angle is that 20～60 degree are best.

In addition, the ribbon conveyer in the present embodiment 2 can be other conveying devices, for example chain-linked conveyer.

In addition, dropped on the chute 7 by the shot that throwed and concentrate on after the place, transferred upward by chain bucket elevator 8, be thrown into separator 9 then, in this separator 9, that the air-flow that produces by precipitron 13 makes is low weight, promptly broken shot and from product W go up by except that under dirty sheet attracted by precipitron 13, and only normal shot is retained hopper 10.The shot that remains in hopper 10 is admitted to shot grenade instrumentation 5 through ingress pipe 12 and is throwed once more.

Embodiment 2

Below, be elaborated at second embodiment that has used shot blasting equipment of the present utility model based on Fig. 4 and Fig. 5.This shot blasting equipment possesses as shown in the figure: chamber 21, and it prevents that the shot that is throwed from splashing, and is respectively equipped with at left and right sidewall that steel plate is taken out of mouthful and steel plate is moved into mouth; Roller ribbon conveyer 22, it is adapted in chamber 21 flatly and connects, and possesses the rotation type roller, steel plate W is taken out of from steel plate mouthful be delivered to steel plate and move into mouth; The

shot grenade instrumentation

23,24 of centrifugal projection-type, they are installed in the roof and the diapire of chamber 21 respectively, the steel plate W projection shot on roller ribbon conveyer 22; 25, shot EGR 25, it supplies with shots to shot

grenade instrumentation

23,24 respectively, and 21 reclaims the shot that is throwed and make the shot circulation from the chamber; Fan 26, it is mounted to and inner is communicated with chamber 21, and generation is blown off and is placed on the compressed air of the shot on the steel plate W.

And as shown in Figure 5, the left and right sidewall outside separately of chamber 21 is separately installed with and prevents that shot from taking out of mouthful and steel plate is moved into mouthful sealing mechanism 27 of the rubber window curtain type that splashes from steel plate.

In addition, shot EGR 25 possesses: chute 28, and it is installed on the bottom of chamber 21; Chain bucket elevator 29, it erects setting and its supply port is communicated with the outlet of chute 28; Separator 30, it is mounted to the mouth of taking out of of chain bucket elevator 29 and is communicated with, and shot is separated with impurity; Hopper 31, the shot outlet that it is installed on separator 30 retains shot temporarily; A plurality of

ingress pipes

33,33, they import

shot grenade instrumentation

23,24 with the shot of hopper 31 respectively across

gate

32,32; Precipitron 34, it is connected with separator 30 with chain bucket elevator 29, is recovered in the dust that produces in the device.

According to aforesaid formation, if under the state that makes roller ribbon conveyer 22, shot

grenade instrumentation

23,24 and shot EGR 25 and fan 26 work, the steel plate W that treats shot-peening is placed on the right upper portion of roller ribbon conveyer 22, then steel plate W is carried by roller ribbon conveyer 22, and in carrying figure, the shot that steel plate W acceptance is throwed from

shot grenade instrumentation

23,24, thus be carried out shot-peening.And, be placed on shot above the steel plate W and blown off from the compressed air of fan 26 and can not remain on the steel plate W.

In addition, dropped on the chute 28 by the shot that throwed and concentrate on after the place, transferred upward by chain bucket elevator 29, be thrown into separator 30 then, then by air-flow in precipitron 34 generations, make low weight, promptly broken shot and go up by the dirty sheet under removing from product W is attracted by precipitron 34, and only normal shot is retained hopper 31.The shot that remains in hopper 31 is admitted to shot

grenade instrumentation

23,24 through ingress pipe 33 and is throwed once more.

In addition, in above-mentioned first, second embodiment, used the device of centrifugal projection-type as

shot grenade instrumentation

5,23,24, but be not limited thereto, for example can certainly being to use, compressed air makes the device of shot from the structure of nozzle ejection.
