In the figure: the air-jet hammer comprises a guide sleeve 1, a piston 2, an outer sleeve 3, a front air chamber 4, an accommodating cavity 5, an air hole 6, a central hole 7, an air passing channel 8 and an impactor body 9.
Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Referring to fig. 3-6, a novel impactor, it includes impactor body 9, impactor body 9 includes outer tube 3, the inside sliding fit of outer tube 3 has piston 2, and the impact end external diameter of piston 2 constitutes sliding fit with the uide bushing 1 that sets up in outer tube 3 inside, and the periphery of uide bushing 1 is equipped with holds the chamber 5, holds and is processed there being gas pocket 6 on the chamber 5, and gas pocket 6 link up with the centre bore 7 of uide bushing 1 mutually. By adopting the impactor with the structure, the kinetic energy of the piston is continuously increased in the stroke from the closing of the air passing channel to the closing of the air hole in the guide sleeve in the stroke motion of the piston, so that the working efficiency of the impactor is further improved, and the impact energy is improved.
Further, in the process of matching the piston 2 with the guide sleeve 1, when the air passage 8 is closed, a front air chamber 4 of a closed space is formed among the guide sleeve 1, the piston 2 and the outer sleeve 3, the front air chamber 4 is communicated with the accommodating cavity 5, the piston 2 moves to continue to compress the front air chamber 4 to reduce the volume of the front air chamber 4, the internal compressed air is discharged to a central air hole of the drill bit through the air hole 6, the stroke continues, when the piston 2 moves to close the air hole 6, the front air chamber 4 forms a closed space, and the internal high-pressure air starts to be compressed. By adopting the specific structure, the high-pressure gas in the front air chamber 4 is pressed into the accommodating cavity 5 in the process that the front air chamber 4 is gradually compressed, and finally enters the central hole 7 of the guide sleeve 1 through the accommodating cavity 5 and the air hole 6; and when the piston 2 seals and closes the air hole 6, the front air chamber 4 and the accommodating cavity 5 form a closed space, and then high-pressure air in the front air chamber is compressed.
The utility model discloses a theory of operation and process:
through arranging the air holes 6 on the guide sleeve 1, in the stroke process, as shown in figures 3 and 4, the piston 2 is matched with the guide sleeve 1, the air passing channel 8 is closed, the volume of the front air chamber 4 is reduced, and the compressed air in the front air chamber is discharged to the central air hole of the drill bit through the air holes 6 on the guide sleeve 1; when the piston moves to close the air hole 6 of the guide sleeve, as shown in fig. 5 and 6, the front air chamber 4 forms a closed space, and high-pressure air in the front air chamber starts to be compressed; the kinetic energy of the piston is continuously increased in the section of the stroke from the closing of the air passage 8 to the closing of the air hole 6 on the guide sleeve, so that the impact energy of the impactor is effectively improved, and the aim of improving the working efficiency is fulfilled.
