Abstract
The utility model provides a kind of technical scheme of grating percussion device, this scheme includes a cross-arm and is fixed on a plurality of gratings on cross-arm, and below each grating, there is a strike bar, this programme is fixed with at least one cross-arm riser in the bottom surface of described cross-arm, cross-arm riser is parallel with described grating axis, has two riser rod holes on described cross-arm riser at least; Bottom at described strike bar is fixedly connected with connecting plate, and connecting plate is parallel with each described cross-arm riser, on described connecting plate with the other end that hits bar and be fixedly connected with end have with cross-arm riser on the identical connecting plate rod hole of riser rod hole number; In described riser rod hole and described connecting plate rod hole, be installed with elasticity pitman.
Description
Technical field
The utility model relates to a kind of grating percussion device that a kind of industrial screening plant, especially Cantilevered screen are used.
Background technology
In the prior art, known technology is that by the utility model people application, Patent Office of State Intellectual Property Office, to authorize the disclosed patent No. be 98122124.6, name is called the technical scheme of " a kind of method for cleaning of Cantilevered screen and device ", the method of this scheme is a good method of cleaning grating, so far still using, but the device of this scheme just exists the defect that structure is too miscellaneous, this is the existing weak point of prior art.
Summary of the invention
The utility model is exactly for the existing deficiency of prior art, and provide a kind of grating percussion device technical scheme, what this scheme employing was connected with strike bar is a small amount of connecting plate, and connecting plate is connected with the cross-arm riser being fixed on cross-arm by elasticity pitman, when cross-arm vibrates, cross-arm riser will drive connecting plate to vibrate by elasticity pitman, and the vibration of connecting plate drives again hits bar vibration strike grating, plays the effect of cleaning grating.
This programme is achieved by the following technical measures: grating percussion device, include a cross-arm and be fixed on a plurality of gratings on cross-arm, and below each grating, there is a strike bar, the feature of this programme is in the bottom surface of described cross-arm, to be fixed with at least one cross-arm riser, cross-arm riser is parallel with described grating axis, has two riser rod holes on described cross-arm riser at least; Bottom at described strike bar is fixedly connected with connecting plate, and connecting plate is parallel with each described cross-arm riser, on described connecting plate with the other end that hits bar and be fixedly connected with end have with cross-arm riser on the identical connecting plate rod hole of riser rod hole number; In described riser rod hole and described connecting plate rod hole, be installed with elasticity pitman.The concrete feature of this programme also has, and connects in addition plate stem hole on described connecting plate, in this connection plate stem hole, is installed with connecting rod.What described elasticity pitman adopted is metallic elastic rod.What described elasticity pitman adopted is non-metallic elastic rod.The cross section of described strike bar is Π shape.What described connecting rod adopted is steel pipe.What described connecting plate adopted is bar-shaped plate.What described cross-arm riser adopted is rectangular flat.
The beneficial effect of this programme can learn according to the narration to such scheme, and because the bottom surface of cross-arm in this scheme is fixed with cross-arm riser, cross-arm riser is parallel with described grating axis, has riser rod hole on described cross-arm riser.In the bottom of hitting bar, be fixedly connected with connecting plate, connecting plate is parallel with each described cross-arm riser, on described connecting plate with the other end that hits bar and be fixedly connected with end have with cross-arm riser on the identical excellent hole of connecting plate of riser rod hole number.In described each riser rod hole and described each connecting plate rod hole, be installed with elasticity pitman.This structure, when screen cloth is worked, cross-arm vibrates with screen cloth simultaneously, and cross-arm drives again the vibration of cross-arm riser, and cross-arm riser will drive again connecting plate to vibrate by elasticity pitman, the vibration of connecting plate drives again hits bar vibration strike grating, plays the effect of cleaning grating.Cross-arm riser drives connecting plate vibration by elasticity pitman, because elasticity pitman has elasticity, so the vibration of connecting plate is asynchronous with the vibration of cross-arm, therefore the strike vibration of bar that can make connecting plate drive is asynchronous with the vibration of grating, makes to hit bar and can effectively hit grating and clear up.The connecting plate negligible amounts of using due to whole screen cloth not only but with cross-arm without being fixedly connected with, make structure become simple and be easy to processing.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
accompanying drawing explanation:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Fig. 3 is the B-B sectional structure schematic diagram of Fig. 1.
In figure, 1 is elasticity pitman, and 2 is cross-arm, and 3 is cross-arm riser, and 4 is connecting rod, and 5 is connecting plate, and 6 for hitting bar, and 7 is grating, and 8 is riser rod hole, and 9 for connecting plate stem hole, and 10 is connecting plate rod hole.
the specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, the grating percussion device of this programme has a cross-arm 2 and is fixed on a plurality of gratings 7 on cross-arm 2, and below each grating 7, has a strike bar 6, and the cross section of described strike bar 6 is Π shape.This programme is fixed with cross-arm riser 3 in the bottom surface of described cross-arm 2, and the cross-arm riser 3 of this specific embodiment has three and what adopt is rectangular flat.Each cross-arm riser 3 is parallel with described grating 7 axis, has two riser rod holes 8 on described cross-arm riser 3 at least, and this specific embodiment has adopted three riser rod holes 8.In the bottom of described strike bar 6, be fixedly connected with connecting plate 5, this specific embodiment has adopted the connecting plate 5 of two bar-shaped plates, each connecting plate 5 is parallel with each described cross-arm riser 3, on each described connecting plate 5 with the other end that hits bar 6 and be fixedly connected with end have with cross-arm riser 3 on the connecting plate rod hole 10 of riser rod hole 8 equal numbers.Each riser rod hole 8 on described cross-arm riser 3 but slightly deviation identical but not corresponding with each connecting plate rod hole 10 quantity on described connecting plate 5, this can guarantee the tension force of elasticity pitman 1 in the time of making to be installed with elasticity pitman 1 in riser rod hole 8 and connecting plate rod hole 10.What described elasticity pitman 1 adopted is metallic elastic rod or nonmetal flexible rod, and what this specific embodiment adopted is metallic elastic rod iron.On each described connecting plate 5, connect in addition plate stem hole 9, in this connection plate stem hole 9, be installed with connecting rod 4, what connecting rod 4 adopted is steel pipe, and this connecting rod 4 is for by each connecting plate 5 stationary positioned, and makes each connecting plate 5 can synchronous vibrations.In this specific embodiment, adopt three cross-arm risers 3 to drive two connecting plates 5 to form a vibration unit, can determine and adopt several groups of vibration units according to the concrete width of screen cloth in actual applications.
