Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and in particular relates to a hydraulic breaker hammer with an auxiliary drill rod and a crusher. Background Art

[0002] Hydraulic breakers are heavy-duty mechanical tools widely used in mining, metallurgy, railways, highways, municipal gardening, construction, and shipbuilding. A breaker is a hydraulic breaker mounted on a mechanical arm, capable of breaking large stones, rocks, ores, etc. into smaller pieces for subsequent processing, transportation, and utilization.

[0003] When a crusher is used to crush large pieces of ore at the mouth of a mine, if it encounters large pieces of ore with sharp triangles, the hammer rod cannot find a point of force. When the rod presses on the sharp corners or inclined surfaces of the ore, it cannot be pressed tightly and is prone to slipping, causing the hammer to be unable to work and affecting work efficiency. At the same time, when the ore is being swept, because the rod and the ore only have a single point of contact, the ore rotates at the origin and cannot fall into the chute as expected. Furthermore, the intelligent crusher can complete the intelligent secondary crushing process of large pieces of ore through logic such as large piece recognition, spatial positioning, path planning, and intelligent control based on a combination of environmental target perception technology and intelligent robot regulation and control technology. When the intelligent crusher is performing intelligent operations, if the hydraulic breaker cannot compact the target ore and cannot quickly sweep and crush the ore, it will affect the intelligent judgment strategy and cause the program to be executed in a loop.

[0033] Hydraulic breakers are heavy-duty mechanical tools widely used in mining, metallurgy, railways, highways, municipal gardening, construction, and shipbuilding. A breaker is a hydraulic breaker mounted on a mechanical arm, capable of breaking large stones, rocks, ores, etc. into smaller pieces for subsequent processing, transportation, and utilization.

[0034] When a crusher is used to crush large pieces of ore at the mouth of a mine, if it encounters large pieces of ore with sharp triangles, the hammer rod cannot find a point of force. When the rod presses on the sharp corners or inclined surfaces of the ore, it cannot be pressed tightly and is prone to slipping, causing the hammer to be unable to work and affecting work efficiency. At the same time, when the ore is being swept, because the rod and the ore only have a single point of contact, the ore rotates at the origin and cannot fall into the chute as expected. Furthermore, the intelligent crusher can complete the intelligent secondary crushing process of large pieces of ore through logic such as large piece recognition, spatial positioning, path planning, and intelligent control based on a combination of environmental target perception technology and intelligent robot regulation and control technology. When the intelligent crusher is performing intelligent operations, if the hydraulic breaker cannot compact the target ore and cannot quickly sweep and crush the ore, it will affect the intelligent judgment strategy and cause the program to be executed in a loop.

[0035] To this end, the utility model provides a hydraulic breaker hammer with an auxiliary drill rod and a crusher using the hydraulic breaker hammer with the auxiliary drill rod, which can solve the positioning problem and the sweeping problem of the drill rod during crushing operations.

[0036] Reference Figure 1 and Figure 2 A hydraulic breaker hammer with an auxiliary drill rod according to one embodiment of the present invention includes a breaker hammer body 100, a first drill rod 200, a hydraulic drive mechanism, and a second drill rod 300. The first drill rod 200 is mounted at the front end of the breaker hammer body 100 so as to be slidable along its own axial direction. The hydraulic drive mechanism is disposed within the breaker hammer body 100 and connected to the first drill rod 200, and is used to control the reciprocating sliding of the first drill rod 200, thereby achieving the impact crushing action of the first drill rod 200. A plurality of second drill rods 300 are provided, and the second drill rods 300 are mounted on the breaker hammer body 100 and located around the first drill rod 200.

[0037] In the traditional structure, the breaker hammer has only a single impact drill rod. When the impact is broken, the ore is easy to move and it is inconvenient to sweep. The hydraulic breaker hammer with an auxiliary drill rod in the utility model is provided with a second drill rod 300 on the breaker hammer body 100. When working, the second drill rod 300 can be used to assist in positioning large pieces of ore, thereby cooperating with the first drill rod 200 to position the ore, and then crushing it based on the impact of the first drill rod 200. Therefore, the hydraulic breaker hammer with an auxiliary drill rod in the utility model can compact the ore for crushing through the first drill rod 200 and the second drill rod 300, and sweep the ore through the cooperation of the first drill rod 200 and the second drill rod 300, thereby solving the positioning problem and sweeping problem of the drill rod during the crushing operation. Moreover, when used in an intelligent crusher, it is conducive to the judgment and smooth operation of the intelligent control program.

[0038] In some embodiments of the present invention, the second drill rod 300 can be slidably mounted on the breaker body 100 along its own axial direction. This structural arrangement allows the second drill rod 300 to be adjusted to match the first drill rod 200 during crushing operations, preventing the second drill rod 300 from pressing against the ore and affecting the impact depth of the first drill rod 200. This also facilitates the crushing of ores of varying shapes and sizes.

[0039] Combine Figure 2 The axis of the second drill rod 300 is parallel to the axis of the first drill rod 200 to facilitate installation and operation control. It is understandable that the axis of the second drill rod 300 and the axis of the first drill rod 200 may have a certain angle, and those skilled in the art can flexibly set it as needed.

[0040] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the breaker body 100 is provided with an installation box 400, and the second drill rod 300 is slidably installed on the installation box 400, and a reset assembly is provided in the installation box 400, which abuts the second drill rod 300 and is used to keep the second drill rod 300 extended forward. With the structural arrangement of this embodiment, the second drill rod 300 is automatically reset by the reset assembly. When abutting the ore, the second drill rod 300 can automatically slide backward to adapt to the outer dimensions of the ore, so that the first drill rod 200 can smoothly abut the ore, thereby ensuring that the first drill rod 200 can smoothly perform the crushing operation. At the same time, the second drill rod 300 can exert a downward pressure on the ore under the action of the reset assembly, thereby compacting and positioning the ore, facilitating the crushing operation of the first drill rod 200.

[0041] Reference Figure 2 In some embodiments of the present invention, a guide hole 403 is provided inside the mounting box 400, and the second drill rod 300 is slidably mounted in the guide hole 403. The provision of the guide hole 403 can effectively ensure the stability of the second drill rod 300 when sliding back and forth, which is conducive to improving the structural stability of the second drill rod 300.

[0042] Reference Figure 2 In some embodiments of the present invention, an installation cavity 402 is provided within the installation box 400. The installation cavity 402 communicates with the guide hole 403. One end of the second drill rod 300 extends into the installation cavity 402 and is provided with a limiting boss 301. The limiting boss 301 protrudes radially from the second drill rod 300, and a reset assembly is disposed within the installation cavity 402. The structural arrangement of this embodiment utilizes the limiting boss 301 to slidably limit the second drill rod 300, while the installation cavity 402 is used to install the reset assembly, which helps to improve the integrity of the installation of the second drill rod 300.

[0043] Reference Figure 2 In some embodiments of the present invention, the cross-section of the mounting cavity 402 is circular, the outer contour of the limiting boss 301 is circular and matches the mounting cavity 402, and the reset assembly includes a reset spring 401, the outer diameter of which matches the inner diameter of the mounting cavity 402. One end of the reset spring 401 abuts the limiting boss 301, and the other end of the reset spring 401 abuts the side wall of the mounting cavity 402. In this embodiment, a sliding guide can also be implemented between the limiting boss 301 and the side wall of the mounting cavity 402, and the guide hole 403 improves the installation stability of the second drill rod 300. At the same time, the inner wall of the mounting cavity 402 is used to limit the reset spring 401, resulting in a streamlined structure and a stable and reliable working relationship.

[0044] Reference Figure 1 and Figure 2 In some embodiments of the present invention, a hydraulic breaker hammer with auxiliary drill rods further includes a bracket 500 . The bracket 500 is provided with two mounting plates 501 , with the breaker body 100 positioned between the two mounting plates 501 . A mounting box 400 is provided on each side of the mounting plates 501 , with each mounting box 400 housing a second drill rod 300 . With the structural arrangement of this embodiment, two second drill rods 300 are provided on either side of the first drill rod 200 to assist in compacting the ore and improve crushing efficiency. Furthermore, the bracket 500 provides for secure installation, resulting in high installation stability.

[0045] Reference Figure 1 In some embodiments of the present invention, bolts 101 passing through the mounting plate 501 are provided between the two mounting boxes 400 to secure them. Specifically, the bolts 101 pass through one mounting box 400, then through the mounting plate 501 and the other mounting box 400, before being tightened with nuts. This embodiment has a simple structural design and high installation efficiency. It is compatible with commercially available breakers, making it easy to add the mounting box 400 and the second drill rod 300 to existing breakers.

[0046] Reference Figures 1 to 4 In some embodiments of the present invention, the front end of the second drill rod 300 normally protrudes forward relative to the first drill rod 200. In this way, when performing a crushing operation, the second drill rod 300 will first abut against the ore to position and compact it, and then the first drill rod 200 will be further controlled to abut against the ore to perform the crushing operation.

[0047] In summary, when encountering pointed and beveled ore, the hammer, in conjunction with the auxiliary drill rod, can compact the ore and immobilize it, allowing the crushing function to proceed normally. When encountering a pile of crushed ore, the three drill rods can be inserted together to perform a raking and sweeping action, effectively processing the remaining ore on the chute grid. This effectively solves the problem of a single drill rod being unable to effectively find the impact point for crushing irregularly shaped ore. It is understood that the number of second drill rods 300 is not limited to two, and their sliding control can also be implemented using an active drive.

[0048] In addition, the present invention further provides a crusher that utilizes a hydraulic breaker hammer with an auxiliary drill rod of any of the aforementioned structures. The crusher of the present invention, by utilizing the hydraulic breaker hammer with the auxiliary drill rod, can compact and crush ore using the first drill rod 200 and the second drill rod 300, and can also perform ore sweeping and sifting by cooperating with the first drill rod 200 and the second drill rod 300, thereby resolving drill rod positioning and sweeping issues during crushing operations.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
