Description

Technical Field

[0001] The utility model relates to the technical field of breaker hammers, in particular to a breaker hammer with dust-proof and splash-proof functions. Background Art

[0002] A breaker hammer is a commonly used crushing device, and its main function is to crush ores or other large materials. It uses the pressure oil provided by an excavator pump station as power, enabling it to more effectively clean the floating stones and the soil in the rock crevices during excavation.

[0003] When the breaker hammer is performing crushing operations on hard stones and concrete, due to the impact of the hammer head, the stone materials are broken into smaller particles. During this process, the stone particles will collide and rub against each other, thus generating a large amount of dust, and the small stone fragments will also splash due to the impact of the hammer head, creating potential safety hazards.

[0004] Currently, the dust-proof device of the breaker hammer usually adopts the method of covering a plastic bucket around the hammer head to prevent dust from escaping. However, in actual use, as the hammer head breaks the object, the surface of the broken object will also become uneven. At this time, the bottom of the protective steel plate cannot fully fit the crushing surface, allowing dust and stones to escape from the gap between the protective steel plate and the crushing surface, resulting in an unsatisfactory dust-proof and splash-proof effect of the protective steel plate. Therefore, it needs to be improved and optimized. Content of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the defects in the prior art, so as to provide a breaker hammer with dust-proof and splash-proof functions.

[0006] A breaker hammer with dust-proof and splash-proof functions includes: a breaker hammer bracket, a driving device, and a breaking head. The breaker hammer bracket, the driving device, and the breaking head are longitudinally connected in sequence. One end of the driving device close to the breaking head is provided with a top plate, and multiple protective steel plates are hinged on the top plate. A flexible protective cover is arranged on the inner wall surface of the protective steel plate. A dust collection box, a fan, and a connecting pipe are arranged on the breaker hammer bracket. The fan is installed above the dust collection box, and the connecting pipe extends from the bottom of the dust collection box to the inside of the flexible protective cover.

[0007] Further, there are paired parallel cross bars and paired parallel vertical bars arranged on the top plate, and the cross bars and the vertical bars are perpendicular to each other.

[0008] Further, a threaded rod is arranged inside the cross bar, and both ends of the threaded rod are respectively connected to the vertical bar. Bolts are arranged at the connection points of the threaded rod and the vertical bar.

[0009] Further, sliders are arranged at both ends of the vertical bar, and guide grooves corresponding to the positions of the sliders are arranged on the top plate.

[0010] Furthermore, a guide rod is also arranged inside the guide groove, and the slider is slidably connected to the guide rod.

[0011] Furthermore, a connecting piece is installed at the bottom of the top plate, and the connecting piece is flexibly connected to the protective steel plate and the flexible protective cover.

[0012] Furthermore, the driving device is a driving cylinder, the top of the driving cylinder is connected to the breaker bracket, and the outer wall surface of the driving cylinder is connected to the cross bar and the vertical bar.

[0013] Furthermore, one end of the connecting pipe located inside the flexible protective cover is a dust suction port, and a filter screen is arranged on the dust suction port.

[0014] Furthermore, a box cover is hinged on the dust collection box.

[0015] Furthermore, the fan is a negative pressure fan, and a breaker handle is arranged above the breaker bracket.

[0016] The technical solution of the present utility model has the following advantages:

[0034] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] As Figures 1 to 7 shown, a breaker with dust-proof and splash-proof functions includes: a breaker bracket 1, a driving device, and a breaker head 11. The breaker bracket 1, the driving device, and the breaker head 11 are longitudinally connected in sequence. One end of the driving device close to the breaker head 11 is provided with a top plate 3. A plurality of protective steel plates 13 are hinged on the top plate 3. A flexible protective cover 14 is provided on the inner wall surface of the protective steel plate 13. A dust collection box 16, a fan, and a connecting pipe 19 are provided on the breaker bracket 1. The fan is installed above the dust collection box 16. The connecting pipe 19 extends from the bottom of the dust collection box 16 to the inside of the flexible protective cover 14.

[0036] The above-mentioned breaker with dust and splash prevention functions has the top plate 3 and the protective steel plate 13 hinged to each other. When the breaker head 11 operates on the breaking surface, the bottom of the protective steel plate 13 always fits the breaking surface. The setting of the protective steel plate 13 blocks the splashing stones. The flexible protective cover 14 is made of rubber, and when the flexible protective cover 14 arranged inside the protective steel plate 13 causes the protective steel plate to open outwards, the flexible protective cover 14 is stretched. The stretched flexible protective cover 14 is used to prevent the dust from drifting out through the gaps between the protective steel plates 13. Compared with the traditional device, this device blocks the dust and stones through the flexible protective cover 14 and the protective steel plate 13, reducing the noise during the operation of the breaker. Through the operation of the fan, the dust is sucked into the dust collection box 16 through the connecting pipe 19, achieving the effect of dust and splash prevention during the operation of the breaker.

[0037] As Figure 2 shown, in this embodiment, a total of four protective steel plates 13 are installed, and the four protective steel plates 13 are evenly distributed on the top plate 3. However, the number of the protective steel plates 13 is not limited to four, and it can also be other numbers. The circular top plate 3 helps the protective steel plates 13 to better fit the breaking surface.

[0038] As Figure 4 and Figure 5 shown, in this embodiment, there are paired parallel cross bars 4 and paired parallel vertical bars 5 on the top plate 3. The cross bars 4 and the vertical bars 5 are perpendicular to each other. The cross bars 4 and the vertical bars 5 jointly enclose an installation opening 12, and the installation opening 12 is used for installing and fixing the driving device.

[0039] As Figure 4 and Figure 5 shown, in this embodiment, a threaded rod 6 is arranged inside the cross bar 4. The two ends of the threaded rod 6 are respectively connected to the vertical bar 5. A bolt 10 is arranged at the connection of the threaded rod 6 and the vertical bar 5. When installing the driving device, first place the driving device in the installation opening 12, and then rotate the bolt 10 to drive the vertical bar 5 to move along the threaded rod 6 until the driving device is fixedly installed.

[0040] As Figure 5 shown, in this embodiment, sliding blocks 7 are arranged at both ends of the vertical bar 5. Guide grooves 8 corresponding to the positions of the sliding blocks 7 are arranged on the top plate 3. Guide rods 9 are also arranged inside the guide grooves 8. The sliding blocks 7 are slidably connected to the guide rods 9. The sliding blocks 7 drive the vertical bar 5 to move along the guide rods 9 in the guide grooves 8, improving the accuracy of the installation process.

[0041] As Figure 6As shown in the figure, in this embodiment, a connecting member 15 is installed at the bottom of the top plate 3, and the connecting member 15 is flexibly connected to the protective steel plate 13 and the flexible protective cover 14. The connecting member 15 is simultaneously flexibly connected to the top plate 3, the protective steel plate 13, and the flexible protective cover 14, improving the connection stability between the top plate 3, the protective steel plate 13, and the flexible protective cover 14. At the same time, the connecting member 15 is made of rubber, which helps to fit the protective steel plate 13 and the flexible protective cover 14 to the crushing surface, achieving the effect of dust and splash prevention for the breaker.

[0042] As Figure 1 shown in the figure, in this embodiment, the driving device is a driving cylinder 2. The top of the driving cylinder 2 is connected to the breaker support 1. The outer wall surface of the driving cylinder 2 is connected to the cross bar 4 and the vertical bar 5. The bottom of the driving cylinder 2 is connected to the breaker head 11. The driving cylinder 2 is used to provide power for the entire breaker device, facilitating the construction operation of the breaker. The connection between the outer wall surface of the driving cylinder 2 and the cross bar 4 and the vertical bar 5 is used to connect the driving cylinder 2 to the lower top plate 3 and the protective steel plate 13.

[0043] As Figure 7 and Figure 8 shown in the figure, in this embodiment, one end of the connecting pipe 19 located inside the flexible protective cover 14 is a dust suction port 20, and a filter screen 21 is provided on the dust suction port 20. The filter screen 21 blocks and filters larger stones.

[0044] As Figure 1 shown in the figure, in this embodiment, a box cover 17 is hinged on the dust collection box 16. Through the hinged box cover 17, it is beneficial to clean the dust after the breaker work is completed.

[0045] As Figure 1 shown in the figure, in this embodiment, the fan is a negative pressure fan 18. A breaker handle is provided above the breaker support 1. The negative pressure fan 18 has the characteristics of large air volume, low noise, low energy consumption, stable operation, long service life, and high efficiency. The breaker handle facilitates the movement and use of the breaker.

[0046] As Figures 1 to 8As shown, in this embodiment, before the crushing operation, the staff first place the driving cylinder 2 into the installation opening 12, and then rotate the bolt 10 clockwise. The rotation of the bolt 10 drives the vertical rod 5 to move towards the cross rod 4. At the same time, the slider 7 at the bottom of the vertical rod 5 slides along the guide rod 9 inside the guide groove 8, improving the stability and accuracy of the installation process. The staff continuously rotates the bolt 10 clockwise until the outer wall surfaces of the two vertical rods 5 and the driving cylinder 2 are tightly connected to each other. Then, the staff starts the negative pressure fan 18 to start the crushing operation. When the crushing head 11 performs the crushing operation, since the top plate 3 and the protective steel plate 13 are hinged to each other, when the crushing head 11 operates on the inclined crushing surface, the bottom of the protective steel plate 13 always fits the crushing surface. At the same time, the side of the connecting member 15 connected to the protective steel plate 13 and the flexible protective cover 14 is stretched. During inclined surface crushing, the crushing surface gradually becomes flat. Due to its own flexible characteristics and under the gravity of the protective steel plate 13, the protective steel plate 13 automatically closes downward, further making the protective steel plate 13 always fit the crushing surface, playing a role in dust prevention. During the crushing operation, the crushing head 11 will press downward. At this time, multiple protective steel plates 13 will open outward. At the same time, a flexible protective cover 14 is provided on the inner wall surface of the protective steel plate 13. Due to its own flexible characteristics, the flexible protective cover 14 can still ensure that it fits the crushing surface even after being stretched, playing a role in dust prevention. Moreover, the flexible protective cover 14 can block the flying stones during crushing, reducing noise and also playing a role in protecting the protective steel plate 13. When dust is generated inside the flexible protective cover 14, the negative pressure fan 18 will also suck the dust inside the flexible protective cover 14 into the dust collection box 16 through the connecting pipe 19 and store it in the dust collection box 16. After the crushing operation is completed, the staff can turn off the negative pressure fan 18 and open the box cover 17 to clean the dust inside the dust collection box 16. At the same time, the staff rotates the bolt 10 counterclockwise, and the vertical rod 5 moves away from the cross rod 4, thereby disassembling the driving cylinder 2.

[0047] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
