[0002] A hydraulic break hammer is a tool commonly used for crushing, demolition, and excavation work. It utilizes the pressure and flow rate of the hydraulic system to generate high-frequency impact forces, which are transmitted to the object to be crushed through the hammer head, thereby achieving the crushing effect.

[0003] A hydraulic break hammer is disclosed in the Chinese utility model patent with the publication number CN217128363U, belonging to the technical field of break hammers. The main problem is that the common hydraulic break hammers on the market have poor anti-seismic effects against impacts. When crushing large rocks, the hydraulic break hammer is affected by the counter-vibration force for a long time, and its internal devices are prone to damage due to vibration. Regarding the above-related technologies, the inventor believes there are the following defects: Although in the above prior art, by providing a housing, the inside of the housing is used to install the hydraulic cylinder body, the mounting hole opened at the bottom of the housing is used to install the breaking cone, and the breaking cone is used to crush large rocks. A buffer protection pad and a shock-absorbing pad are provided. The shock-absorbing pad is used to protect the hydraulic cylinder body, and the buffer protection pad is used to buffer and protect the inside of the housing to prevent damage to the internal devices of the housing due to excessive vibration when using the device; during the outdoor ore mining process, a large amount of dust is easily generated and covers the outer peripheral surface of the break hammer. If the surface of the break hammer is damaged due to force during use, due to the coverage of the dust, the user cannot directly and clearly observe the damage to the outer periphery of the break hammer, resulting in the inability to repair it in time. After continued use, the break hammer is completely damaged and cannot be used, affecting the normal service life of the break hammer. Therefore, a hydraulic break hammer with a long service life is needed, which can clean the outer periphery of the break hammer during its use to ensure the cleanliness of its outer periphery, so that the user can timely observe the usage condition of the break hammer and perform maintenance in time, thereby improving the service life of the hydraulic break hammer. Summary of the Utility Model

[0004] To solve the technical problem that if the surface of the break hammer is damaged due to force during use, due to the coverage of the dust, the user cannot directly and clearly observe the damage to the outer periphery of the break hammer, resulting in the inability to repair it in time and affecting the normal service life of the break hammer, the utility model provides a hydraulic break hammer with a long service life.

[0005] The present utility model is realized by the following technical solutions: A hydraulic breaker with a long service life, including a connecting shell and a hammer rod. A fixing sleeve is installed on the outer periphery of the connecting shell, and a pneumatic cleaning mechanism is arranged on the fixing sleeve for cleaning the outer periphery of the hammer rod. The pneumatic cleaning structure includes a fixing ring, a high-pressure air pump, a first hinge seat, an electric push rod, a second hinge seat, a high-pressure air nozzle, a connecting pipe and a telescopic hose;

[0006] Among them, the fixing ring is installed on the outer periphery of the fixing sleeve, multiple groups of the high-pressure air pumps are annularly distributed and installed through the inside of the fixing ring, multiple groups of the first hinge seats are annularly distributed and installed at the bottom of the fixing sleeve, the electric push rod is movably installed at the bottom of the first hinge seat, and the second hinge seat is movably connected to the bottom end of the push rod of the electric push rod.

[0007] Preferably, multiple groups of the high-pressure air nozzles are distributed and installed at the bottom of the second hinge seat, multiple groups of the connecting pipes are annularly distributed and penetrate through the inside of the fixing sleeve, and one end of the connecting pipe is connected to the high-pressure air pump.

[0008] Preferably, the telescopic hose is installed at the output end of the high-pressure air nozzle, and one end of the telescopic hose is communicated with the other end of the connecting pipe.

[0009] Preferably, a window is penetrated and opened on the front wall of the connecting shell, which is convenient for users to observe the working state of the hammer rod lifting.

[0010] Preferably, a hydraulic pressure pump is installed on the top of the connecting shell for providing pressure to the hammer rod.

[0011] Preferably, a connecting frame is installed on the top of the hydraulic pressure pump, and a connecting wire is installed on one side of the hydraulic pressure pump.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] By adjusting the telescopic lengths of the two groups of electric push rods, the present utility model can drive the high-pressure air nozzle to adjust the angle, so that the output port of the high-pressure air nozzle faces the direction of the hammer rod. Since a large amount of dust is easily generated during the outdoor ore mining process of the hydraulic breaker and covers the outer peripheral surface of the breaker, the user can start the high-pressure air pump during the working process of the hammer rod to discharge high-pressure air flow outward by its internal compressor. The high-pressure air flow is transmitted to the high-pressure air nozzle through the connecting pipe and the telescopic hose, and finally the high-pressure air flow is sprayed from the high-pressure air nozzle to the outer periphery of the hammer rod. The impact force of the high-pressure air flow is used to complete the cleaning of the dust covering the outer peripheral surface of the hammer rod, ensuring the cleanliness of the outer periphery of the hammer rod, so that the user can observe the usage condition of the breaker in time and perform maintenance in time, thereby improving the service life of the hydraulic breaker.

[0019] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0020] Embodiment 1: Please refer to Figure 1 - Figure 4 , a hydraulic breaker with a long service life in this embodiment includes a connecting shell 1 and a hammer rod 3. A connecting wire 15 is installed on one side of the hydraulic pressure pump 13, and the hydraulic pressure pump 13 is installed on the top of the connecting shell 1 to provide pressure for the hammer rod 3. A connecting frame 14 is installed on the top of the hydraulic pressure pump 13. A window 12 is penetrated and opened on the front wall of the connecting shell 1 to facilitate the user to observe the working state of the lifting of the hammer rod 3. The connecting wire 15 provides electric power for the hydraulic pressure pump 13. Through the rotary motion of the hydraulic pressure pump 13, the external oil fluid is compressed and transported into the pump body to generate a certain pressure. When the pressure of the high-pressure oil reaches a certain value, the pressurization work of the hammer rod 3 is completed, and the ore is split by using the extremely large splitting force released by the hammer rod 3 outward in the narrow hole;

[0021] Further, a fixed sleeve 2 is installed on the outer periphery of the connecting shell 1, a fixed ring 4 is installed on the outer periphery of the fixed sleeve 2, a plurality of high-pressure air pumps 5 are annularly distributed and penetrated and installed inside the fixed ring 4, a plurality of first hinge seats 6 are annularly distributed and installed at the bottom of the fixed sleeve 2, an electric push rod 7 is movably installed at the bottom of the first hinge seat 6, a second hinge seat 8 is movably connected to the bottom end of the push rod of the electric push rod 7, a plurality of high-pressure air nozzles 9 are distributed and installed at the bottom of the second hinge seat 8, a plurality of connecting pipes 10 are annularly distributed and penetrated inside the fixed sleeve 2, and one end of the connecting pipe 10 is connected to the high-pressure air pump 5. A telescopic hose 11 is installed at the output end of the high-pressure air nozzle 9, and one end of the telescopic hose 11 is communicated with the other end of the connecting pipe 10;

[0022] Furthermore, a pneumatic cleaning mechanism is provided on the fixed sleeve 2 for cleaning the outer periphery of the hammer rod 3. The pneumatic cleaning structure is composed of a fixed ring 4, a high-pressure air pump 5, a first hinge seat 6, an electric push rod 7, a second hinge seat 8, a high-pressure air nozzle 9, a connecting pipe 10 and a telescopic hose 11. The high-pressure air nozzle 9 is movably installed at the bottom of the fixed sleeve 2 through the cooperation of the first hinge seat 6, the electric push rod 7 and the second hinge seat 8. Two groups of electric push rods 7 are movably installed at the top of each group of high-pressure air nozzles 9. By adjusting the telescopic lengths of the two groups of electric push rods 7, the high-pressure air nozzle 9 can be driven to adjust the angle, so that the output port of the high-pressure air nozzle 9 faces the direction of the hammer rod 3. Since a large amount of dust is easily generated during the outdoor ore mining process of the hydraulic breaker and covers the outer peripheral surface of the breaker, the user can start the high-pressure air pump 5 during the working process of the hammer rod 3 to discharge high-pressure air flow outward by using the compressor inside it. The high-pressure air flow is transmitted to the high-pressure air nozzle 9 through the connecting pipe 10 and the telescopic hose 11, and finally the high-pressure air nozzle 9 sprays the high-pressure air flow to the outer periphery of the hammer rod 3. The impact force of the high-pressure air flow is used to complete the cleaning of the dust covering the outer peripheral surface of the hammer rod 3, ensuring the cleanliness of the outer periphery of the hammer rod 3, so that the user can timely observe the usage condition of the breaker, perform timely maintenance, and improve the service life of the hydraulic breaker.

[0023] Working principle: The pressurization of the hammer rod 3 is completed by the hydraulic pressurization pump 13. The hammer rod 3 releases a great splitting force outward in a narrow hole to split the ore material. Since a large amount of dust is easily generated during the outdoor ore mining process of the hydraulic breaker and covers the outer peripheral surface of the breaker, the user can start the high-pressure air pump 5 during the working process of the hammer rod 3 to discharge high-pressure air flow outward by using the compressor inside it. The high-pressure air flow is transmitted to the high-pressure air nozzle 9 through the connecting pipe 10 and the telescopic hose 11, and finally the high-pressure air nozzle 9 sprays the high-pressure air flow to the outer periphery of the hammer rod 3. The impact force of the high-pressure air flow is used to complete the cleaning of the dust covering the outer peripheral surface of the hammer rod 3, ensuring the cleanliness of the outer periphery of the hammer rod 3, so that the user can timely observe the usage condition of the breaker, perform timely maintenance, and improve the service life of the hydraulic breaker.

[0024] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
