Technical Field

[0001] This utility model relates to the field of hydraulic breakers, specifically to a shock-absorbing hydraulic breaker. Background Technology

[0002] Hydraulic breakers have become an important tool in hydraulic excavators. Their main power source is pressurized oil supplied by the pump station on the excavator or loader. They can more effectively clear loose rocks and soil from rock crevices when excavating building foundations, and have become an important tool for compacting buildings.

[0003] A search revealed that Chinese patent application CN 217128363U discloses a hydraulic breaker. It includes an outer casing, the interior of which is used to mount a hydraulic cylinder body. Mounting holes at the bottom of the casing are used to mount a crushing cone, which is used to crush large rocks.

[0004] However, the following technical problems still exist when implementing the above technical solutions: there is operational vibration between the hydraulic breaker and the housing, and long-term vibration can cause the connection between the hydraulic breaker and the housing to loosen, causing the hydraulic breaker to detach from the housing. Furthermore, when the hydraulic breaker crushes rocks, there is a risk of small stones being splashed during the crushing process, which greatly endangers the personal safety of the workers.

[0005] Therefore, the present invention urgently needs to solve the problem of providing a hydraulic breaker that can reduce the vibration between the breaker and the housing during use, avoid the problem of loosening of the connection between the hydraulic breaker and the support frame due to long-term operation vibration, and at the same time, can block the crushing of small stones to avoid the danger of small stones splashing when the hydraulic breaker crushes stones. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issues in the prior art where there is operational vibration between the hydraulic breaker and the housing, which over a long period can lead to loosening of the connection between the hydraulic breaker and the housing, causing the hydraulic breaker to detach from the housing. Furthermore, when the hydraulic breaker is used to break rocks, there is a risk of small fragments being ejected during the breaking process. Therefore, this invention provides a shock-absorbing hydraulic breaker that reduces vibration between the hydraulic breaker and the housing during use, preventing loosening of the connection between the hydraulic breaker and the support frame due to prolonged operational vibration. Simultaneously, it can also prevent the ejection of small fragments during the breaking process, thus avoiding the risk of small fragments being ejected when the hydraulic breaker is breaking rocks.

[0007] To achieve the above objectives, this utility model provides a shock-absorbing hydraulic breaker, comprising: an outer casing and a liftable breaker disposed within the outer casing; the outer casing is provided with multiple sets of buffer mechanisms at intervals along the circumference of the breaker for buffering the breaker during crushing, and a dustproof mechanism to prevent small stones from flying during crushing; wherein...

[0008] The dustproof mechanism includes: a slidable dust cover fitted onto the outer casing and located around the breaker hammer, always in contact with the ground.

[0009] Preferably, the dustproof mechanism further includes: a second spring, a fixing plate, and a locking assembly; wherein,

[0010] The outer casing is slidably fitted with a fixing plate. The dust cover and the fixing plate are connected by a plurality of spaced and fixed second springs. The fixing plate is provided with a locking component for fixing the fixing plate on the outer casing.

[0011] Preferably, the locking assembly includes: a insertion rod, a limiting block, and a tension spring; wherein,

[0012] A rod is slidably inserted into the fixed plate. The side wall of the outer casing has a hole for use with the rod. A limiting block is fixed at the top of the rod, and a tension spring is sleeved on the rod, with its two ends abutting against the side walls of the fixed plate and the limiting block, respectively.

[0013] Preferably, a pull ring is fixedly provided on the surface of the limiting block.

[0014] Preferably, the buffer mechanism includes: a sliding sleeve, a sliding rod, a limiting plate, and a first spring; wherein,

[0015] The outer casing is hinged with a sliding sleeve, and a sliding rod is slidably fitted inside the sliding sleeve. One end of the sliding rod is hinged to a fixing ring fixedly fitted on the breaker hammer, and a limiting plate is fixedly fitted at the other end of the sliding rod. A first spring is fitted on the sliding rod, with its two ends respectively abutting against the inner side wall of the sliding sleeve and the side wall of the limiting plate.

[0016] Preferably, the buffer mechanism further includes a damping spring sleeved on the breaker hammer, the two ends of which are respectively abutted against the bottom surface of the breaker hammer and the top surface of the fixing ring.

[0017] Preferably, the dust cover has a trapezoidal cross-section that is smaller at the top and larger at the bottom.

[0018] Preferably, a rubber pad is fixed inside the pull ring.

[0019] According to the above technical solution, this utility model provides a shock-absorbing hydraulic breaker. The beneficial effects during use are as follows: When the hydraulic breaker starts working, the breaker rises and falls within the outer casing and impacts the target object. During the crushing process, the impact force generated by the breaker is transmitted to the ground through the outer casing. Simultaneously, small stones and dust begin to fly. Due to its characteristic of always being in contact with the ground, the dust cover forms a barrier around the breaker. This barrier effectively prevents small stones and dust generated during the crushing process from flying outwards, protecting the safety and cleanliness of the surrounding environment. When the breaker impacts the target object, multiple sets of buffer mechanisms begin to work, absorbing and dispersing the impact force generated by the breaker. This helps reduce wear on the breaker and the outer casing, while improving the stability and safety of the crushing operation.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0033] Reference Figures 1-7 As shown, a shock-absorbing hydraulic breaker includes: an outer casing 100 and a liftable breaker 101 disposed within the outer casing 100. The outer casing 100 is fixedly provided with multiple sets of buffer mechanisms 200 at intervals along the circumference of the breaker 101 for buffering the breaker 101 during crushing, and a dustproof mechanism 300 for preventing small stones from flying during crushing.

[0034] The dustproof mechanism 300 includes: a dust cover 301 that is slidably sleeved on the outer casing 100 and located around the breaker 101, always in contact with the ground.

[0035] When a crushing operation is required, the hydraulic breaker starts working. The breaker 101 rises and falls within the outer casing 100 and impacts the target object. During the crushing process, the impact force generated by the breaker 101 is transmitted to the ground through the outer casing 100. At the same time, small stones and dust are generated and begin to fly. Due to its characteristic of always being in contact with the ground, the dust cover 301 forms a barrier around the breaker 101. This barrier effectively prevents small stones and dust generated during the crushing process from flying outward, protecting the safety and cleanliness of the surrounding environment. When the breaker 101 impacts the target object, multiple sets of buffer mechanisms 200 start working to absorb and disperse the impact force generated by the breaker 101. This helps to reduce the wear of the breaker 101 and the outer casing 100, while improving the stability and safety of the crushing operation.

[0036] Reference Figures 2-3As shown, the dustproof mechanism 300 further includes: a second spring 302, a fixing plate 303, and a locking assembly 400; wherein,

[0037] A fixing plate 303 is slidably sleeved on the outer casing 100. The dust cover 301 and the fixing plate 303 are connected by a plurality of second springs 302 fixed at intervals. The fixing plate 303 is provided with a locking component 400 for fixing the fixing plate 303 on the outer casing 100.

[0038] In the above scheme, when the breaker 101 operates on different ground surfaces or at different angles, the dust cover 301 will adaptively adjust according to the unevenness of the ground or the tilt angle of the breaker. The second spring 302 provides elasticity to keep the dust cover 301 in contact with the ground at all times to ensure the dustproof effect. By operating the locking component 400, the fixing plate 303 is fixed in an appropriate position on the outer casing 100. The locking component 400 ensures that the fixing plate 303 and the dust cover 301 will not shift due to vibration or impact during operation.

[0039] Reference Figure 3 As shown, the locking assembly 400 includes: a insertion rod 401, a limiting block 402, and a tension spring 403; wherein,

[0040] A rod 401 is slidably inserted into the fixing plate 303. The side wall of the outer casing 100 is provided with a insertion hole 404 for use with the rod 401. A limiting block 402 is fixedly provided at the top of the rod 401, and a tension spring 403 is sleeved on the rod 401, with both ends abutting against the side walls of the fixing plate 303 and the limiting block 402 respectively.

[0041] In the above scheme, the insertion rod 401 is slidably inserted into the fixed plate 303. Through the cooperation of the limiting block 402 and the tension spring 403, the insertion rod 401 can be locked and unlocked. When it is necessary to lock the fixed plate 303, the insertion rod 401 is inserted into the insertion hole 404 of the outer casing 100. The tension spring 403 maintains the locked state of the insertion rod 401. After the insertion rod 401 is locked, the elasticity of the tension spring 403 maintains the locked state, ensuring the stability of the fixed plate 303 and the dust cover 301 during operation, preventing displacement due to vibration or impact, and improving operational safety. When it is necessary to unlock the fixed plate 303, the elasticity of the tension spring 403 is overcome, and the limiting block 402 is pulled upwards, causing the insertion rod 401 to be pulled out of the insertion hole 404, thus unlocking the plate.

[0042] Reference Figure 3 As shown, a pull ring 405 is fixedly provided on the surface of the limiting block 402.

[0043] When it is necessary to unlock the plug rod 401, the operator directly pulls the pull ring 405. The pull ring 405 drives the limit block 402 and the plug rod 401 to move upward against the elastic force of the tension spring 403, so that the plug rod 401 is pulled out from the insertion hole 404 of the outer casing 100, thereby unlocking. The design of the pull ring 405 makes it easier for the operator to pull the limit block 402 and the plug rod 401, improving the convenience of locking and unlocking operations.

[0044] Reference Figures 4-7 As shown, the buffer mechanism 200 includes: a sliding sleeve 201, a sliding rod 202, a limiting plate 204, and a first spring 205; wherein,

[0045] The outer casing 100 is hinged with a sliding sleeve 201, and a sliding rod 202 is slidably sleeved inside the sliding sleeve 201. One end of the sliding rod 202 is hinged to a fixing ring 203 fixedly sleeved on the breaker hammer 101, and a limiting plate 204 is fixedly sleeved on the other end of the sliding rod 202. A first spring 205 is sleeved on the sliding rod 202, and its two ends are respectively abutted against the inner side wall of the sliding sleeve 201 and the side wall of the limiting plate 204.

[0046] When the hydraulic breaker 101 is performing a crushing operation, it is subjected to an impact force and moves downward. The hydraulic breaker 101 drives the slide rod 202 to slide within the sliding sleeve 201 via the fixing ring 203. The sliding of the slide rod 202 compresses the first spring 205, and the first spring 205 generates a reaction force to buffer the impact force of the hydraulic breaker 101. At the same time, the limiting plate 204 prevents the slide rod 202 from coming out of the sliding sleeve 201. The introduction of the first spring 205 effectively absorbs the impact force generated by the hydraulic breaker 101 during the crushing process, reduces damage to the outer sleeve 100 and the hydraulic breaker 101 itself, and improves the service life and operational stability of the hydraulic breaker.

[0047] Reference Figures 4-7 As shown, the buffer mechanism 200 further includes a damping spring 206 sleeved on the breaker hammer 101, with both ends of the damping spring 206 abutting against the bottom surface of the breaker hammer 101 and the top surface of the fixing ring 203, respectively.

[0048] When the hydraulic breaker 101 is performing crushing operations, in addition to the buffering effect of the first spring 205, the damping spring 206 also starts to work. The two ends of the damping spring 206 abut against the bottom surface of the hydraulic breaker 101 and the top surface of the fixing ring 203, respectively. When the hydraulic breaker 101 is subjected to impact force, the damping spring 206 generates damping force, further slowing down the moving speed of the hydraulic breaker 101. The damping spring 206 and the first spring 205 work together to provide a more stable buffering effect for the hydraulic breaker 101.

[0049] Reference Figures 1-3As shown, the cross-section of the dust cover 301 is a trapezoidal shape with a smaller upper end and a larger lower end.

[0050] In the above scheme, the cross-section of the dust cover 301 is designed as a trapezoid with a smaller top and a larger bottom. This design allows the dust cover 301 to form a larger contact area when it comes into contact with the ground, thereby more effectively blocking small flying stones.

[0051] Reference Figure 3 As shown, a rubber pad is fixed inside the pull ring 405.

[0052] When it is necessary to unlock the fixing plate 303, the operator pulls the limiting block 402 outward by grasping the pull ring 405, causing the insertion rod 401 to be pulled out of the insertion hole 404. Because a rubber pad is fixed inside the pull ring 405, this design provides the operator with a better grip and comfort when pulling the ring 405. At the same time, the rubber pad also reduces friction between the operator's hand and the pull ring 405, protecting the hand from injury.

[0053] In summary, the shock-absorbing hydraulic breaker provided by this utility model, during use, inserts the insertion rod 401 into the insertion hole 404 on the outer casing 100. The tension spring 403 keeps the insertion rod 401 in a locked state. As needed, the position of the insertion rod 401 can be adjusted by the pull ring 405 and the limiting block 402 so that the fixing plate 303 can be unlocked when needed, and the hydraulic breaker can be started. The breaker 101 rises and falls within the outer casing 100 to break the target. The buffer mechanism 200's slide rod 202, the first spring 205, and the resistance... The nylon spring 206 works together to buffer the breaker hammer, reducing vibration and impact. During the crushing process, the dust cover 301 is always in contact with the ground to prevent small stones from flying. The dust cover 301 is connected to the fixed plate 303 through the second spring 302 and has a certain elasticity to adapt to uneven ground. After the crushing operation is completed, the hydraulic breaker hammer is turned off. If it is necessary to disassemble or adjust the dust cover mechanism 300, the limit block 402 is pulled outward through the pull ring 405 to pull the insertion rod 401 out of the insertion hole 404 and unlock the fixed plate 303.
