[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 2 , Figure 3 and Figure 4The utility model provides an embodiment: a breaker hammer capable of quickly replacing a drill rod, comprising a shell 3, a mounting block 14 being fixedly connected to the upper surface of the shell 3, a fixing rod 5 being rotatably connected inside the shell 3, the fixing rod 5 being rotatably connected inside the mounting block 14, a gear 1 4 being fixedly connected to the lower surface of the fixing rod 5, a plurality of sliding holes 13 being provided inside the gear 1 4, a sliding rod 6 being slidably connected inside the sliding hole 13, a positioning block 1 7 being fixedly connected to one end of the sliding rod 6, a connecting shaft 30 being fixedly connected inside the gear 1 4, a positioning block 2 8 being rotatably connected to one side of the outer wall of the connecting shaft 30, a positioning block 1 7 being slidably connected to the inside of the positioning block 1 8 on one side of the outer wall, a fixing block 11 being fixedly connected to the inside of the shell 3, and the fixing block 11 A motor 9 is fixedly connected to the upper surface, a rotating shaft 10 is fixedly connected to the output end of the motor 9, a gear 2 12 is fixedly connected to one side of the outer wall of the rotating shaft 10, the gear 2 12 is meshed and connected with the gear 1 4, a protective shell 2 is fixedly connected to the outer wall of the shell 3, a sealing plate 17 is slidably connected inside the protective shell 2, a pull rope 19 is arranged inside the sealing plate 17, one end of the pull rope 19 is fixedly connected to an insert block 18, a limiting component for limiting the insert block 18 is installed on one side of the outer wall of the pull rope 19, the limiting component includes a spring 1 20, the spring 1 20 is fixedly connected between the sealing plate 17 and the insert block 18, one side of the outer wall of the insert block 18 is slidably connected inside the sealing plate 17, and one side of the outer wall of the insert block 18 is slidably connected inside the protective shell 2;

[0025] Specifically, when the drill rod body 29 needs to be replaced, we need to start the motor 9, and its output end rotates, driving the rotating shaft 10 fixedly connected thereto to rotate smoothly; the gear 2 12 fixed by the fixing rod 5 on one side of the rotating shaft 10 is meshed and connected with the gear 1 4, and a transmission system is formed between them; so as the gear 1 4 rotates, the slide bar 6 slides in the smooth slide hole 13, so that the positioning block 1 7 fixedly connected below slides out inside the positioning block 2 8, just like unlocking a lock, and finally the positioning block 2 8 can be separated from the housing 3, so that the connecting block 28 fixedly connected to the positioning block 2 8 can be easily taken out. If the motor 9 is damaged and needs to be maintained, it is necessary to pull the pull rope 19, which will pull and drive the plug block 18 to move with it, so that the plug block 18 leaves the protective shell 2, thereby releasing the positioning state of the sealing plate 17 in the protective shell 2. At this time, the sealing plate 17 can be easily taken out, so that the motor 9 can be maintained, and the plug block 18 can be returned to its position through the elasticity of the spring 1 20.

[0026] Reference Figure 1 , Figure 2 and Figure 5, symmetric mounting brackets 16 are fixedly connected to the outer wall of the mounting block 14 in the up and down directions. A plurality of mounting rods 15 are fixedly connected inside the two mounting brackets 16. A frame 1 is fixedly connected to one side of the outer wall of the mounting rod 15. A dust reduction cover 21 is fixedly connected to the lower surface of the frame 1. A pressing plate 24 is slidably connected inside the dust reduction cover 21. A dial plate 23 is fixedly connected to one side of the outer wall of the pressing plate 24. One side of the outer wall of the dial plate 23 is slidably connected inside the dust reduction cover 21. A placement plate 22 is slidably connected inside the dust reduction cover 21. A second spring 26 is fixedly connected inside the placement plate 22. A latch 25 is slidably connected inside both the dust reduction cover 21 and the placement plate 22. The latch 25 is fixedly connected to one end of the second spring 26. A placement side plate 27 is fixedly connected to one side of the outer wall of the placement plate 22. The lower surface of the outer shell 3 is in fit connection with the connection block 28. The lower surface of the positioning block two 8 is fixedly connected to the upper surface of the connection block 28. A drill rod body 29 is fixedly connected to the lower surface of the connection block 28;

[0027] Specifically, the mounting block 14 is fixedly connected to the upper surface of the outer shell 3, which plays a role in stably fixing the overall disassembly and assembly structure. The mounting block 14 is firmly fixedly connected to the inside of the frame 1 through the two mounting brackets 16; finally, when the sound insulation cotton needs to be replaced, we need to gently push down the dial plate 23, which drives the pressing plate 24 to slowly press down on the lower latch 25. During this process, both the latch 25 and the second spring 26 move downward. As the pressure increases, the second spring 26 gradually contracts. Eventually, the second spring 26 is completely compressed, and the latch 25 moves into the inside of the placement plate 22. At this time, the positioning effect between the placement plate 22 and the dust reduction cover 21 is released. Finally, by pulling gently with the handle on the outer wall of the placement plate 22, the placement plate 22 can be taken out of the dust reduction cover 21, and thus the sound insulation cotton can be replaced.

[0028] Working principle: When the drill rod body 29 needs to be replaced, start the motor 9. The output end of the motor drives the rotating shaft 10 fixedly connected thereto to rotate. One side of the outer wall of the rotating shaft 10 is fixedly connected to the second gear 12. Therefore, the second gear 12 rotates synchronously with the output end of the motor 9. Then, the second gear 12 is meshed with the first gear 4. Therefore, the motor 9, the second gear 12 and the first gear 4 are connected by transmission. The first gear 4 is fixed in a stable position by the fixed rod 5. When it rotates, the sliding rod 6 slides in the sliding hole 13. In this way, the first positioning block 7 fixedly connected to the lower surface of the sliding rod 6 moves accordingly and slides out of the second positioning block 8. Thus, the second positioning block 8 can be separated from the inside of the housing 3, and then the connecting block 28 and the drill rod body 29 can be taken out, so that the drill rod body 29 can be taken out. When the motor 9 needs to be repaired, pull the pull rope 19. The movement of the pull rope 19 pulls the insertion block 18 to move, so that the insertion block 18 is separated from the protective housing 2, and then the positioning effect of the sealing plate 17 on the protective housing 2 is released. Thus, the sealing plate 17 can be easily taken out to repair the motor 9. The mounting block 14 is fixedly connected to the upper surface of the housing 3. The mounting block 14 is fixed in the frame 1 by two mounting brackets 16. Thus, the overall stability of the device is improved. When the sound insulation cotton needs to be replaced, dial the dial plate 23 downward to drive the pressing plate 24 to press against the lower clamping block 25. When the clamping block 25 and the second spring 26 are compressed into the placement plate 22, the placement plate 22 can be released from the positioning effect on the dust reduction cover 21. Finally, the placement plate 22 can be taken out of the dust reduction cover 21 through the handle on the outer wall of the placement plate 22, and the sound insulation cotton can be replaced.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
