The fixture of fixing described endshield and guard shield;
Limit torn open by endshield, and it is fixedly arranged on the outside of the endshield in described exit.
As an embodiment of the present utility model, on described impeller head body, the side relative with described import also offers connecting hole, described endshield offers first circular hole corresponding with described import and second circular hole corresponding with described connecting hole.
As an embodiment of the present utility model, described first circular hole and the second circular hole are oppositely arranged.
As an embodiment of the present utility model, described import is connected with external pipe by the first circular hole, and described connecting hole is connected with external motor by the second circular hole.
As an embodiment of the present utility model, limit torn open by described endshield is the platy structure stretched out from the side of the described endshield in described exit.
As an embodiment of the present utility model, limit torn open by described endshield and described endshield is perpendicular.
As an embodiment of the present utility model, described fixture is square head screw.
The beneficial effects of the utility model: compared with prior art, impeller head protector of the present utility model, it can avoid shot to be driven on screw, avoid the equipment fault that screw weares and teares and endshield loosens and produces, the service life of backplate and screw can also be extended simultaneously, in addition in the work of cleaning ball blast, the irregular movement of shot, the shot that direct projection and bounce-back are torn open on limit to end plate endshield can be beaten on workpiece by secondary bullet, plays secondary cleaning effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein:
Fig. 1 is the structural representation of the utility model impeller head protector;
Fig. 2 is the schematic side view of Fig. 1.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
Alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Refer to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of the utility model impeller head protector; Fig. 2 is the schematic side view of Fig. 1.As depicted in figs. 1 and 2, described impeller head protector comprise impeller head body, endshield 4, top backplate 3, guard shield 1, lamina tecti 2, fixture and endshield tear limit 6 open.
Described impeller head body, it is formed with inner chamber 81, the import 82 be connected with described inner chamber 81 and exports 83.Described import 82 is connected with external pipe 9, entering for shot, and shot enters in inner chamber 81 to be driven to carry out rotating by rotatable parts (not shown) and then throws away from described outlet 83.Side relative with described import 82 on described impeller head body also offers connecting hole 84, described endshield 4 offers first circular hole 41 corresponding with described import 82 and second circular hole 42 corresponding with described connecting hole 84.Described first circular hole 41 and the second circular hole 42 are oppositely arranged.Described import 82 is connected with external pipe 9 by the first circular hole 41, and described connecting hole 84 is connected with external motor (not shown) by the second circular hole 42.
Limit 6 torn open by described endshield is the platy structures stretched out from the side of the described endshield 4 at described outlet 83 place.The outside that limit 6 is fixedly arranged on described endshield 4 torn open by described endshield.In this embodiment, be unlikely to when dishing out inner chamber 81 to make shot to get on relative impeller head, described endshield 4 has predetermined safe distance apart from described outlet 83.
Described top backplate 3, it is positioned at the top of described impeller head body and covers described endshield 4.
Described guard shield 1, it is sheathed on the periphery of described endshield 4, carries out second protection to the parts in it.
Described lamina tecti 2, it is positioned at the top of described top backplate 3 and covers described guard shield 1 and top backplate 3.
Described fixture 5, it is for fixing described endshield 4 and guard shield 1.In this embodiment, described fixture 5 is several square head screws.In other embodiments, this fixture 5 can also be other fixed parts.
It is perpendicular with described endshield 4 that limit 6 torn open by described endshield.After the shot in inner chamber 81 is got from outlet 83, the rebound effect of tearing limit 6 open due to this endshield just avoids shot and is driven on screw 5, thus avoids the equipment fault that screw 5 weares and teares and endshield loosens and produces, and extends the service life of backplate and screw.Moreover in the work of cleaning ball blast, the irregular movement of shot, the shot making direct projection and bounce-back tear open on limit to end plate endshield can be beaten on workpiece by secondary bullet, plays secondary cleaning effect.
Impeller head protector of the present utility model, it can avoid shot to be driven on screw, avoid the equipment fault that screw weares and teares and endshield loosens and produces, the service life of backplate and screw can also be extended simultaneously, in addition in the work of cleaning ball blast, the irregular movement of shot, the shot that direct projection and bounce-back are torn open on limit to end plate endshield can be beaten on workpiece by secondary bullet, plays secondary cleaning effect.
Above-mentioned explanation fully discloses detailed description of the invention of the present utility model.It is pointed out that the scope be familiar with person skilled in art and any change that detailed description of the invention of the present utility model is done all do not departed to claims of the present utility model.Correspondingly, the scope of claim of the present utility model is also not limited only to previous embodiment.
