Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to an air intake channel for the front shell of a hydraulic breaker with built-in multi-stage cyclone dust removal. Background Technology

[0002] Excavator breakers are hydraulic breaking devices mounted on excavators, mainly used for breaking hard materials such as rocks and concrete. Their box-type hydraulic structure has become the mainstream design in the global market. This type significantly reduces working noise and carrier vibration by optimizing the hammer body protection mechanism, while solving the problem of easy loosening of the housing in traditional equipment. As a core functional component of excavators, this equipment is widely used in mining, building demolition and other scenarios. The popularization of box-type hydraulic technology marks the transformation of breakers from impact-type to protective design. This technical route has become the mainstream development trend in the global market since 2013.

[0003] For example, an impact breaker hammer (authorization announcement number CN205550373U) relates to the field of mining and crushing technology. It includes a hammer handle, a breaker rod, a connecting part, bolts, a reinforcing layer, an impact structure, a blowing device, and a lifting connection device. The outer surface of the hammer handle is provided with an integrally cast reinforcing layer. The lower part of the hammer handle is narrower than the upper part. The bottom end of the breaker rod is the hammer head. The upper end of the breaker rod is connected to the connecting part. The upper end of the connecting part has a cavity that mates with the lower end of the hammer handle. The hammer handle and the breaker rod are detachably connected by bolts on the connecting part. The breaker rod is connected to the impact mechanism, which is located in the middle of the lower end of the connecting part. Two symmetrical blowing devices are provided at the bottom of the connecting part. A lifting connection device is provided at the top of the hammer handle.

[0004] The above-mentioned device does not require the replacement of the entire breaker hammer through the lifting connection device, which reduces costs and the shattered debris can be removed in time.

[0024] Example 1:

[0025] Please see Figures 1-5This utility model discloses an air intake channel for the front shell of a hydraulic breaker with a built-in multi-stage cyclone dust removal system. The system includes a front shell assembly 1, a multi-stage cyclone dust removal assembly 2, a dust collection assembly 3, and a dust collection assembly 4. The front end of the front shell assembly 1 is slidably connected to the multi-stage cyclone dust removal assembly 2, and the front end of the multi-stage cyclone dust removal assembly 2 is fixedly connected to the dust collection assembly 3. The lower end of the multi-stage cyclone dust removal assembly 2 is fixedly connected to the dust collection assembly 4. The front shell assembly 1 also includes a front shell 11 slidably connected to the multi-stage cyclone dust removal assembly 2, threaded grooves 12 located at both ends of the front shell 11, a pin 13 fixedly connected to the upper rear side of the front shell 11, a long bolt 14 threadedly connected to the front shell 11 through the threaded groove 12, a short screw 15 threadedly connected to the front shell 11 through the threaded groove 12, and the short screw 15 can be connected to an external cylinder. The middle of a nut 16 is threadedly connected to the right end of the long bolt 14. The long bolt 14 and the short screw 15 are slidably connected to the dust removal shell assembly 21 through a slot 22.

[0026] The multi-stage cyclone dust collector assembly 2 has a dust collector housing assembly 21 with its rear end slidably connected to the front housing 11. Slots 22 are located at both ends of the dust collector housing assembly 21. A first-stage cyclone dust collector housing 23 is fixedly connected inside the dust collector housing assembly 21. A differential pressure sensor 24 is fixedly connected to the upper right air inlet of the first-stage cyclone dust collector housing 23. When dusty air enters the first-stage cyclone dust collector housing 23, the differential pressure sensor 24 on the first-stage cyclone dust collector housing 23 can be activated to detect the pressure at the air inlet of the first-stage cyclone dust collector housing 23. A first-stage outlet duct 25 is fixedly connected to the upper end of the differential pressure sensor 24. A differential pressure sensor 24 is fixedly connected to the front left side of the first-stage outlet duct 25. A second-stage cyclone dust collector housing 26 is fixedly connected inside the dust collector housing assembly 21. When pre-filtered air is transported to the second-stage cyclone dust collector housing 26 through the first-stage outlet duct 25, the differential pressure sensor 24 on the first-stage outlet duct 25 can be activated to detect the pressure at the first-stage outlet duct. The pressure inside pipe 25 is detected by measuring the pressure difference between the air inlet of the primary cyclone dust collector 23 and the purified air outlet of the primary air outlet pipe 25. This quantifies the system's operating resistance (i.e., pressure loss) and reflects the real-time working status of the primary cyclone dust collector 23. Simultaneously, when the air after secondary purification is discharged through the secondary air outlet pipe 27, the differential pressure sensor 24 can be activated to detect the pressure inside the secondary air outlet pipe 27. The real-time working status of the secondary cyclone dust collector 26 is detected by the pressure difference between the primary air outlet pipe 25 and the secondary air outlet pipe 27. The upper right side of the secondary cyclone dust collector 26 is fixedly connected to the left end of the primary air outlet pipe 25. The secondary air outlet pipe 27 is fixedly connected to the upper end of the secondary cyclone dust collector 26. The left end of the secondary air outlet pipe 27 is fixedly connected to the dust collector assembly 21 and extends out of the left end of the dust collector assembly 21. The differential pressure sensor 24 is fixedly connected to the left side of the middle part of the secondary air outlet pipe 27.

[0027] The dust collection assembly 3 has a dust collection duct 31 fixedly connected to the front end of the dust collection housing assembly 21. A multi-inlet partition plate 32 is fixedly connected to the lower hollow groove of the dust collection duct 31. A coarse dustproof net 33 is fixedly connected between the multi-inlet partition plate 32 and the dust collection duct 31. The front left side of the dust conveying pipe 34 is fixedly connected to the upper right side of the dust collection duct 31. A fan 35 is fixedly connected to the rear end of the dust conveying pipe 34 and is fixedly connected to the inside of the right side of the dust collection housing assembly 21. After the fan 35 is started, it can draw air from the dust collection duct 31 through the dust conveying pipe 34 and deliver it to the dust blowing head 36. The dust blowing head 36 delivers the air to the first-stage cyclone dust collection housing 23. The dust blowing head 36 is fixedly connected to the left end of the fan 35. The left end of the dust blowing head 36 is fixedly connected to the upper right end of the first-stage cyclone dust collection housing 23.

[0028] This utility model provides an improved air intake channel for the front shell of a hydraulic breaker with built-in multi-stage cyclone dust removal, and its working principle is as follows:

[0029] First, when using this device, place it in the work area and then connect it to an external power source to provide the necessary electrical energy for its operation.

[0030] Secondly, when this device is needed, the controller 43 can be used to start the fan 35. After the fan 35 starts, air from the suction duct 31 can be drawn in through the dust conveying pipe 34 and delivered to the dust blowing head 36. The dust blowing head 36 then delivers the air to the first-stage cyclone dust collector housing 23. At the same time, when external air enters the suction duct 31, it can pass through the coarse dustproof net 33, which performs preliminary purification and filtration of dust. Multiple inlets are formed by the multi-inlet partition plate 32, which disperses the airflow, avoids eccentric rotation caused by single-sided air intake, improves airflow symmetry, and enhances the centrifugal force separation efficiency of particles. When dusty air enters the first-stage cyclone dust collector housing 23, the differential pressure sensor 24 on the first-stage cyclone dust collector housing 23 can be activated to detect the pressure at the air inlet of the first-stage cyclone dust collector housing 23. The air after preliminary filtration is then delivered to the first-stage outlet pipe 25. When the air is inside the secondary cyclone dust collector housing 26, the differential pressure sensor 24 on the primary outlet duct 25 can be activated to detect the pressure inside the primary outlet duct 25. By measuring the pressure difference between the air inlet of the primary cyclone dust collector housing 23 and the purified air outlet of the primary outlet duct 25, the system operating resistance (i.e., pressure loss) is quantified, reflecting the real-time working status of the primary cyclone dust collector housing 23. At the same time, when the air after secondary purification is discharged through the secondary outlet duct 27, the differential pressure sensor 24 can be activated to detect the pressure inside the secondary outlet duct 27. The real-time working status of the secondary cyclone dust collector housing 26 is detected by the pressure difference between the primary outlet duct 25 and the secondary outlet duct 27. Multiple sets of differential pressure sensors 24 can send the detected data to the controller 43 for processing and control via data lines. The controller 43 can evaluate the aging of the filter material or the wear degree of the cyclone unit through long-term differential pressure trend analysis.

[0031] Example 2:

[0032] Please see Figures 1-5 Compared to Embodiment 1, this utility model provides an air intake channel for the front shell of a hydraulic breaker with a built-in multi-stage cyclone dust removal system. This embodiment further includes: a dust collection assembly 4; an anti-backflow hopper 41 with its upper end fixedly connected to the lower ends of the primary cyclone dust removal shell 23 and the secondary cyclone dust removal shell 26; a dust collection and discharge pipe 42 fixedly connected to the lower end of the anti-backflow hopper 41 and the lower end of the dust removal shell assembly 21; a controller 43 fixedly connected to the left end of the anti-backflow hopper 41; a water pump 44 fixedly connected to the middle of the upper end of the dust collection and discharge pipe 42; a water supply pipe 45 fixedly connected to the front end of the water pump 44; the upper end of the water supply pipe 45 fixedly connected to an external water tank; and an atomizing nozzle frame 46 fixedly connected to the front end of the dust collection and discharge pipe 42, with the middle of the upper end of the atomizing nozzle frame 46 fixedly connected to the water supply pipe 45.

[0033] In this embodiment:

[0034] When dust collection and discharge are required, the dust-laden air entering the primary cyclone dust collector 23 or the secondary cyclone dust collector 26 begins to flow in a downward spiral towards the anti-backflow hopper 41. The diameter of the cyclone cone gradually decreases, increasing the gas velocity. An external vortex generates an additional internal vortex near the center of the primary cyclone dust collector 23 or the secondary cyclone dust collector 26. This internal vortex spirals upward towards the primary outlet duct 25 or the secondary cyclone dust collector 26, completing the purification process. Through inertia, dust particles collide with the primary cyclone dust collector 23 or the secondary cyclone dust collector 26. The dust is discharged from the inner wall of the primary cyclone dust collector 26 into the anti-backflow hopper 41. The dust in the anti-backflow hopper 41 can fall into the dust collection and discharge pipe 42 for collection due to gravity. At the same time, the water pump 44 can be started by the controller 43. After the water pump 44 is started, water in the external water tank can be drawn out through the water supply pipe 45 and transported to the atomizing nozzle frame 46 for atomization and spraying to suppress dust in the dust collection and discharge pipe 42 and prevent dust from being stirred up and flowing back into the primary air outlet pipe 25 or the secondary cyclone dust collector 26. After the dust suppression is completed, the dust can be discharged through the right end of the dust collection and discharge pipe 42.

[0035] This utility model provides an improved air intake channel for the front shell of a hydraulic breaker with built-in multi-stage cyclone dust removal. By setting a dust collection component 4 to remove dust from the air intake channel, the device can remove dust from the intake air and prevent the air intake channel from being blocked, thus avoiding equipment damage.
