Technical Field

[0001] This utility model relates to the field of hydraulic hydraulic breakers, and more specifically, to a splash-proof structure for hydraulic breakers. Background Technology

[0002] A hydraulic breaker is a tool used to break hard materials such as rocks and concrete. It uses hydraulic principles to achieve high-frequency impact force, thereby quickly breaking the target object. Hydraulic breaker is commonly used in mining, construction, demolition and other fields, and can carry out rock breaking operations efficiently and accurately. However, some problems still exist in the use of existing hydraulic breaker.

[0003] Currently, during the process of hydraulic breakers breaking hard objects such as roads and buildings, the problem of flying debris is easily generated, which can easily cause injury to personnel and equipment. In addition, the breaking process generates a lot of dust, polluting the environment. Therefore, we have made improvements to this issue and proposed an anti-splash structure for hydraulic breakers.

[0031] In this embodiment: When crushing ore, the protective cover 4 is set outside the drill rod 2. When the crushed stone is splashed, it will be blocked by the protective cover 4. The sliding rod 502 is slidably connected inside the fixed cylinder 501. A spring 504 is fixedly installed inside the fixed cylinder 501. The elastic force of the spring 504 can hold the fixed cylinder 501 and the protective cover 4 in place, so that when the breaker is working, the protective cover 4 is always in contact with the ground, avoiding the splashing of crushed stone and thus preventing injury to personnel and equipment.

[0032] like Figure 1 - Figure 4 As shown, based on the above embodiments, in order to enable the anti-splash device of the hydraulic hammer crusher to limit the fixed cylinder 501, this embodiment provides the following design:

[0033] In a preferred embodiment, the limiting plate 503 is slidably connected inside the fixed cylinder 501, and the upper end surface of the sliding rod 502 is fixedly installed on the lower surface of the connecting plate 3.

[0034] In this embodiment, the limiting plate 503 is fixedly installed on the upper surface of the sliding rod 502 and is slidably connected inside the fixed cylinder 501. It can limit the fixed cylinder 501 and prevent the fixed cylinder 501 from sliding out of the sliding rod 502, thus affecting the use of the protective cover 4.

[0035] like Figure 1 - Figure 5 As shown, based on the above embodiments, in order to facilitate the installation of the protective cover 4 on the anti-splash device of the hydraulic hammer crusher, this embodiment provides the following design:

[0036] In a preferred embodiment, the installation mechanism 6 includes a fixing block 601, which is fixedly installed on both sides of the breaker body 1. An installation block 602 is fixedly installed on the upper surface of the connecting plate 3. An installation groove 603 is provided on the bottom surface of the fixing block 601, and the installation block 602 and the installation groove 603 are connected by a snap-fit ​​connection.

[0037] In this embodiment, the mounting block 602 is engaged with the mounting slot 603 to facilitate the installation of the connecting plate 3 and the protective cover 4.

[0038] like Figure 5 As shown, based on the above embodiments, in order to enable the anti-splash device of the hydraulic hammer crusher to be fixedly connected to the protective cover 4, this embodiment provides the following design:

[0039] In a preferred embodiment, the mounting block 602 has a sliding groove 604 inside, and two sliding plates 605 are slidably connected inside the sliding groove 604. A locking block 606 is fixedly installed on one side surface of the sliding plate 605. Both sides of the mounting groove 603 have locking slots 607, and the connection between the locking block 606 and the locking slot 607 is a snap-fit ​​connection.

[0040] In this embodiment: both sliding plates 605 are slidably connected inside the sliding groove 604, and a locking block 606 is fixedly installed on the surface of the sliding plate 605. The locking block 606 is engaged with the locking groove 607 to facilitate the fixed installation of the mounting block 602 inside the fixing block 601.

[0041] In a preferred embodiment, a drive motor 608 is fixedly mounted on one side surface of the mounting block 602, and a threaded rod 609 is fixedly connected to the output end of the drive motor 608. The threads at both ends of the threaded rod 609 are in opposite directions, and the two ends of the threaded rod 609 are respectively threadedly connected to two sliding plates 605.

[0042] In this embodiment: by starting the drive motor 608, the threaded rod 609 at the output end can be rotated. Since the threads at both ends of the threaded rod 609 are opposite, the two sliding plates 605 can be driven to move relative to each other, so that the locking block 606 on the surface of the sliding plate 605 can be locked into the locking groove 607 to fix the mounting block 602.

[0043] like Figure 1 - Figure 3 As shown, based on the above embodiments, in order to enable the anti-splash device of the hydraulic hammer crusher to suppress dust generated during the crushing process, this embodiment provides the following design:

[0044] In a preferred embodiment, the dust suppression mechanism 7 includes a fixed pipe 701, which is fixedly installed on the top of the protective cover 4. An atomizing nozzle 702 is fixedly installed at the bottom of the fixed pipe 701, and a connecting hose 703 is fixedly installed at the upper end of the fixed pipe 701. The other end of the connecting hose 703 is connected to the booster pump and the water tank.

[0045] In this embodiment: the fixed pipe 701 is fixedly installed inside the protective cover 4, and the lower end of the fixed pipe 701 is fixedly installed with an atomizing nozzle 702, and the upper end is connected with a connecting hose 703. Water in the water tank can be drawn out by an external booster pump and sprayed out from the atomizing nozzle 702 through the connecting hose 703 and the fixed pipe 701 to suppress the dust generated by the crushing and avoid affecting the environment.

[0046] When crushing ore, the protective cover 4 is set outside the chisel 2. When the crushed stone is splashed, it will be blocked by the protective cover 4. The sliding rod 502 and the limiting plate 503 on the surface are slidably connected inside the fixed cylinder 501. A spring 504 is fixedly installed inside the fixed cylinder 501. The elastic force of the spring 504 can hold the fixed cylinder 501 and the protective cover 4 in place, so that the protective cover 4 is always in contact with the ground when the breaker is working, avoiding the splashing of crushed stone and thus preventing injury to personnel and equipment. At the same time, the external booster pump can be started to extract external water, which is then sprayed out from the atomizing nozzle 702 through the connecting hose 703 and the fixed pipe 701 for dust suppression.

[0047] When the protective cover 4 needs to be installed, the mounting block 602 on the surface of the connecting plate 3 is inserted into the mounting groove 603 on the lower surface of the fixing block 601. The drive motor 608 is started to drive the threaded rod 609 at the output end to rotate. Since the threads at both ends of the threaded rod 609 are opposite, the two sliding plates 605 can be driven to move relative to each other, so that the locking block 606 on the surface of the sliding plate 605 is inserted into the locking groove 607, fixing the mounting block 602 and achieving the purpose of fixing the protective cover 4. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
