Detailed Description

As shown in figure 1, the air shock knocking hammer comprises a cylinder body 1, a plurality of mounting plates 3 are fixed on the outer edge of the lower end of the cylinder body 1, a cover body 2 is fixedly and hermetically connected to the upper end of the cylinder body 1, an air inlet nozzle 18 communicated with the interior of the cylinder body 1 is fixed on the upper end of the cover body 2, an upper baffle ring 5 is fixed on the upper portion in the cylinder body 1, a piston 4 is slidably and hermetically connected with the cylinder body 1 below the upper baffle ring 5, a rubber pad 6 is fixed on the lower end of the upper baffle ring 5, a rubber tube 6 is tightly abutted against the upper end of the piston 4, an air tube 7 is fixed on the upper end of the piston 4, the air tube 7 penetrates through an opening in the cover body 2 and is slidably and hermetically connected with a sealing sleeve 8 in the opening, an air hole 9 is formed in the air tube 7 in the sealing sleeve 8, a lower baffle ring 11 is fixed in the cylinder body 1 below the piston 4, a mandril 12 penetrating through the lower baffle, the lower extreme threaded connection of ejector pin 12 has swivel nut 13, and swivel nut 13 outer fringe is fixed with outer ring gear 14, and the terminal surface is fixed with sheet rubber 15 under the ejector pin 12 in the swivel nut 13, sheet rubber 15 is hard rubber, and sheet rubber 15 lower extreme and swivel nut 13 lower extreme parallel and level have all been seted up through-hole 16 in the barrel 1 left and right sides, and rack 17 runs through the through-hole 16 of one side and meshes with outer ring gear 14.

When the utility model is used, compressed air enters the cylinder 1 above the piston 4 through the air inlet nozzle 18, the compressed air enables the piston 4 to rapidly move downwards and compress the spring 10, at the moment, the air pipe 7 also moves downwards along with the piston 4, the lower end of the ejector rod 12 knocks a pipeline or a hopper for containing materials, powder attached to, adhered or blocked in the pipeline or the hopper is impacted to be loosened, when the lower end of the ejector rod 12 knocks the pipeline or the hopper, the air hole 9 of the air pipe 7 communicates the air pipe 7 with the cylinder 1 above the piston 4, compressed air in the cylinder 1 above the piston 4 enters the air pipe 7 through the air hole 9 to be discharged, the pressure in the cylinder 1 above the piston 4 is reduced, under the elastic action of the spring 10, the spring 10 enables the piston 4 to move upwards, after the air hole 9 of the air pipe 7 enters the sealing sleeve 8, the air pressure in the cylinder 1 above the piston 4 continues to rise, thereby the piston 4 drives the ejector, and the lower end of the ejector rod 12 is knocked on the pipeline or the hopper, and the piston 4 and the ejector rod 12 reciprocate, so that the pipeline or the hopper is intermittently knocked, and material blockage is prevented. When needs are with in the air shock strikes and strikes the hammer and use plastics material pipeline or hopper, make rack 17 get into and discharge from left through-hole 6 from the through-hole 16 on right side, the in-process of rack 17 motion, rack 17 makes swivel nut 13 rotate on ejector pin 12 through outer ring gear 14 and goes upward, after rack 17 discharges from left through-

hole

16, 15 lower extremes of sheet rubber are located swivel nut 13 below, afterwards, ejector pin 12 will strike the pipeline or the hopper of plastics material through sheet rubber 15, prevent that the pipeline or the hopper of plastics material from being damaged. When the air shock knocking hammer is required to be applied to a metal pipeline or hopper, the rack 17 enters from the through hole 16 on the left side and is discharged from the through hole 16 on the right side, in the moving process of the rack 17, the rack 17 enables the threaded sleeve 13 to rotate on the ejector rod 12 through the outer toothed ring 14 and move downwards, after the rack 17 is discharged from the through hole 16 on the right side, the threaded sleeve 13 is restored, and then the ejector rod 12 can knock the metal pipeline or hopper through the threaded sleeve 13. The utility model discloses, convenient operation through changing the tup, makes its pipeline and hopper that can be applicable to different materials, and application scope is wide, simple structure, and convenient maintenance is efficient.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
