Description

Technical Field

[0001] This utility model relates to the field of engineering crushing devices, and in particular to a crushing device. Background Technology

[0002] Existing hydraulic breakers mounted on robots or vehicle bodies are equipped with collection devices to gather the broken stones or ores. These stones or ores are often irregular in shape and have mostly smooth surfaces. The structural layout of the breaker and collection devices on most existing crushing robots or vehicles is unreasonable, leading to poor vehicle stability, low work efficiency, and complex control. In engineering crushing operations, because the stones or ores are irregularly shaped and mostly have smooth surfaces, they easily escape the crusher's crushing range, exhibiting a degree of uncontrollability. This results in many breakers being unable to efficiently crush stones or ores. When hydraulic breakers are used underwater, issues such as underwater static pressure can cause their working speed to be slow, further reducing work efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the deficiencies and defects mentioned in the background art above, and to provide a crusher and crusher with a clamping device that has a reasonable structural layout, multiple operating modes, and high underwater working efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0005] A crusher with a gripping device includes a housing, a gripping device, and a crushing hammer. The gripping device is rotatably disposed at the lower end of the housing via a first driving member for driving the gripping device to join and grab stones (or ore) or to open and release stones. The crushing hammer is slidably disposed in the inner cavity of the housing. A second driving member is provided between the housing and the crushing hammer for driving the housing to slide relative to the crushing hammer so that the crushing hammer extends out of the housing to crush stones or retracts into the housing to avoid stones.

[0006] In this invention, when the housing and the breaker hammer move relative to each other, the breaker hammer is fixed to the crusher's robotic arm and remains stationary. The second driving component drives the housing to slide on the breaker hammer, thereby adjusting the position of the breaker hammer and the housing. That is, the aforementioned actions of extending the breaker hammer out of the housing to crush rocks or retracting it inward to avoid rocks are achieved by the housing sliding while the breaker hammer remains stationary. For example, extending the breaker hammer out of the housing to crush rocks means the housing moves in the opposite direction to the crushing end of the breaker hammer; retracting the breaker hammer inward to avoid rocks means the housing moves relative to the crushing end of the breaker hammer, causing the breaker hammer to retract back into the housing. Here, the breaker hammer can partially retract into the housing, preferably completely. This configuration makes crushing and avoiding rocks easier and more flexible, and places lower requirements on the crushing stroke of the breaker hammer.

[0007] In the aforementioned crusher, preferably, the housing includes a first shell plate and a second shell plate disposed opposite to each other, and a plurality of connecting posts for connecting the first shell plate and the second shell plate. The first shell plate is parallel to the second shell plate, and the plurality of connecting posts are perpendicularly fixed between the first shell plate and the second shell plate. This housing layout maximizes the utilization of the perimeter area of ​​the housing, resulting in maximum space utilization, providing maximum space for the movement of the breaker hammer and clamping device, minimizing interference, and also saving manufacturing costs to some extent. The number of connecting posts needs to ensure that the first shell plate and the second shell plate are fixedly connected; for example, four connecting posts may be used.

[0008] In the aforementioned crusher, preferably, slide rails are provided on the inner walls of the first and second shell plates, and a slider is provided on the crushing hammer. The crushing hammer is disposed within the inner cavity of the shell through the sliding engagement of the slider and the slide rails. The crushing hammer retracts relative to the shell through the sliding engagement of the slider and the slide rails, and, in conjunction with the clamping device, achieves various operating modes. After the crushing hammer breaks the stone or ore, it retracts back into the shell, and the clamping device can immediately clamp the crushed stone or ore resources and send them into the hopper or other ore storage point. The close and compact relative position of the crushing hammer and the clamping device allows the crushing hammer to save time significantly when carrying out certain dredging and crushing operations, thereby improving work efficiency.

[0009] In the aforementioned crusher, preferably, the lower ends of the first and second shell plates are provided with mounting holes for the clamping device. The clamping device is rotatably mounted in the mounting holes via a rotating shaft. The clamping device, rotating via the shaft, can clamp objects outside the crushing range into the crushing range of the breaker hammer. This increases the working range of the breaker hammer to some extent. The clamping device also helps to clamp and stabilize objects during crushing, preventing them from slipping out of the crusher's crushing range. This avoids frequent detachment of rocks or ore from the crushing range due to insufficient controllability, thereby improving the efficiency of the crushing operation.

[0010] In the aforementioned crusher, preferably, the first driving component is a hydraulic driving component, including a first hydraulic rod and a first hydraulic cylinder. The end of the first hydraulic rod away from the first hydraulic cylinder is hinged to the clamping device, and the first hydraulic cylinder is rotatably sleeved on the connecting column. The first hydraulic rod plays a driving role, and the first hydraulic cylinder plays a fixing role. Through the extension and retraction of the first hydraulic rod, the clamping device can move relative to the outside of the housing, thus avoiding interference with the breaker hammer located in the inner cavity of the housing. At the same time, the first hydraulic cylinder can rotate with the rotation of the clamping device, increasing the flexibility of the clamping grab's movement. Its placement makes the entire structure more compact.

[0011] In the aforementioned breaker, preferably, the second driving component is a hydraulic driving component, including a second hydraulic rod and a second hydraulic cylinder. The second driving component is vertically arranged, and the end of the second hydraulic rod away from the second hydraulic cylinder is fixed to the connecting column. The housing moves synchronously with the second hydraulic rod, and the second hydraulic cylinder is fixed to the breaker hammer. The second hydraulic rod plays a driving role, and the second hydraulic cylinder plays a fixing role. Through the extension and retraction movement of the second hydraulic rod, the connecting column drives the housing to move in the vertical direction, realizing the relative extension and retraction movement of the breaker hammer relative to the interior of the housing.

[0012] In the aforementioned crusher, preferably, the clamping device includes a pair of arc-shaped clamping grabs, which are rotatably disposed on opposite sides of the lower end of the housing. Each arc-shaped clamping grab includes multiple clamping fingers arranged in parallel. The shape of the clamping grabs resembles that of a human hand, including the palm and back of the hand. When the hydraulic rod of the first driving member extends outward from the hydraulic cylinder, it drives the two clamping grabs to move towards each other and achieve clamping; when the hydraulic rod of the first driving member retracts into the hydraulic cylinder, the two clamping grabs move away from each other, releasing the clamped object. Setting the clamping grabs in an arc shape allows for clamping larger objects as much as possible, improving work efficiency. The number of the first driving member corresponds to the number of clamping grabs, and individual control of the driving member increases control flexibility. The multiple parallel clamping fingers, due to the gaps between them, reduce the performance impact caused by water pressure during operation in water, improving the working efficiency of the clamping grabs.

[0013] In the aforementioned breaker, preferably, the breaker hammer includes a breaking rod, a hydraulically driven piston, and a rod chamber. One end of the breaking rod is movably disposed in the rod chamber, and the movable end of the hydraulically driven piston is connected to the breaking rod. Using hydraulic drive improves the breaker hammer's responsiveness and breaking capacity, and also enhances its compatibility with a range of large machinery such as excavators, underwater mining vehicles, and underwater dredging vehicles. Since the first drive component, the second drive component, and the breaker hammer are all hydraulically controlled, control costs are saved, installation, disassembly, and maintenance efficiency are improved, and it is easily applicable to deep-water environments.

[0014] In the aforementioned breaker, preferably, a water passage hole is provided on the drill rod cavity, and the drill rod cavity is connected to the outside. During underwater operation, the water passage hole allows water to enter the drill rod cavity, and the water pressure on the top and bottom of the drill rod is equal, thereby offsetting the performance impact of the deep water hydrostatic pressure on the top of the drill rod and improving the working efficiency of the breaker.

[0015] As a general technical concept, this utility model also provides a crusher, including a crusher arm and the aforementioned crusher. The crusher arm and the breaker hammer are movably connected (hinged) via a third driving component, allowing the crusher to be adjusted at multiple angles through the extension and retraction of the third driving component, making the crushing operation more flexible and efficient. The structure of the aforementioned third driving component can be the same as that of the first and second driving components, for example, it can be hydraulically driven.

[0016] Preferably, the aforementioned crusher also includes a deep-water hydraulic system that is matched with the crusher. The deep-water hydraulic system is equipped with a pressure compensation device that can compensate for the effect of underwater static pressure on the breaker hammer.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] By combining the crusher with the gripping device through a housing, the problem of unreasonable structural layout of the crusher and collection device on crushing robots or crushing vehicles is solved, saving space, improving efficiency, and reducing operational difficulty. By setting up a first and second driving component, the housing, gripping device, and crushing hammer move relative to each other, with each component's movement controlled separately and independently. This enables three different operating modes for the crusher: individual gripping; crushing first and then gripping; and gripping first and then crushing, improving the crusher's operational maneuverability and flexibility.

[0030] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, the crusher with a clamping device in this embodiment includes a housing 1, a clamping device 2, and a crushing hammer 3. The clamping device 2 is rotatably disposed at the lower end of the housing 1 via a first driving member 4 for driving the clamping device 2 to join and grab stones or to open and release stones. The crushing hammer 3 is slidably disposed in the inner cavity of the housing 1, and a second driving member 5 is provided between the housing 1 and the crushing hammer 3 for driving the housing 1 to slide relative to the crushing hammer 3 so that the crushing hammer 3 extends out of the housing 1 to crush stones or retracts into the housing 1 to avoid stones.

[0033] In this embodiment, the housing 1 includes a first shell plate 11 and a second shell plate 12 disposed opposite to each other, and four connecting posts 13 for connecting the first shell plate 11 and the second shell plate 12. The first shell plate 11 is parallel to the second shell plate 12, and the four connecting posts 13 are vertically fixed between the first shell plate 11 and the second shell plate 12. The inner cavity of the housing 1 is through, facilitating the sliding of the breaker hammer 3. In other embodiments, the housing 1 may be configured as a box type, etc.

[0034] In this embodiment, two slide rails 14 are provided on the inner wall surfaces of the first shell plate 11 and the second shell plate 12, and two sliders 31 are provided on the breaker hammer 3. The breaker hammer 3 is disposed in the inner cavity of the shell 1 through the sliding engagement of the sliders 31 and the slide rails 14. In other embodiments, the number of slide rails 14 and sliders 31 is determined according to the actual situation.

[0035] In this embodiment, the lower ends of the first shell plate 11 and the second shell plate 12 are provided with mounting holes 15 for the clamping device 2. The clamping device 2 is rotatably disposed in the mounting holes 15 via a rotating shaft.

[0036] In this embodiment, the first driving component 4 is a hydraulic driving component, including a first hydraulic rod 41 and a first hydraulic cylinder 42. The end of the first hydraulic rod 41 away from the first hydraulic cylinder 42 is hinged to the clamping device 2, and the first hydraulic cylinder 42 is rotatably sleeved on the connecting column 13.

[0037] In this embodiment, the second driving component 5 is a hydraulic driving component, including a second hydraulic rod 51 and a second hydraulic cylinder 52. The second driving component 5 is vertically arranged. The end of the second hydraulic rod 51 away from the second hydraulic cylinder 52 is fixed to the connecting column 13. The housing 1 moves synchronously with the second hydraulic rod 51, and the second hydraulic cylinder 52 is fixed to the breaker hammer 3. By extending the second hydraulic rod 51, the connecting column 13 drives the housing 1 to move downward, thereby causing the breaker hammer 3 to retract relative to the interior of the housing 1. By retracting the second hydraulic rod 51, the connecting column 13 drives the housing 1 to move upward, thereby causing the breaker hammer 3 to extend relative to the interior of the housing 1.

[0038] In this embodiment, the clamping device 2 includes a pair of arc-shaped clamping grippers 21, which are rotatably disposed on opposite sides of the lower end of the housing 1. Each arc-shaped clamping gripper 21 includes multiple clamping fingers arranged side by side. The arc-shaped clamping grippers 21 resemble the shape of a human hand. When the first hydraulic rod 41 of the first driving member 4 extends outward from the first hydraulic cylinder 42, it drives the two clamping grippers 21 to move towards each other and achieve a closed clamping action. When the first hydraulic rod 41 of the first driving member 4 retracts inward from the first hydraulic cylinder 42, the two clamping grippers 21 move away from each other, thereby opening and releasing the clamped object. There are two first driving members 4, which independently control the movement of the clamping grippers 21. The first hydraulic cylinder 42 is attached to the clamping grippers 21 and can rotate with the rotation of the clamping grippers 21. In other embodiments, the first hydraulic cylinder 42 may also be attached to the housing 1 and does not rotate with the rotation of the clamping grippers 21.

[0039] In this embodiment, the hydraulic breaker 3 includes a breaking rod 32, a hydraulically driven piston, and a rod cavity. One end of the breaking rod 32 is movably disposed in the rod cavity, and the movable end of the hydraulically driven piston is connected to the breaking rod 32.

[0040] The crusher in this embodiment includes a crusher arm 6 and a crusher. The crusher arm 6 is hinged to the crusher hammer 3 via a third drive member 7.

[0041] In this embodiment, the crusher can be operated in the following ways:

[0042] Individual clamping: The clamping devices 2 on both sides of the housing 1 open and close via the first drive member 4. In the individual clamping operation, the clamping devices 2 are first opened to face the stone. Then, the stone is covered by the clamping devices 2 through the movement of the crusher robotic arm 6. After the covering action is completed, the clamping grab 21 is closed by the first drive member 4. Finally, the stone is transported to the corresponding position by the crusher robotic arm 6. This process realizes the individual clamping operation of the crusher.

[0043] First crush, then clamp: The hydraulic breaker 3 achieves the telescopic movement of the hydraulic breaker 3 relative to the housing 1 through the second driving component 5. In the operation mode of first crushing and then clamping, the clamping devices 2 on both sides of the housing 1 first open through the first driving component 4. Then the hydraulic breaker 3 extends and connects to the housing 1 through the second driving component 5 and presses against the stone to crush it. After the stone is crushed, the hydraulic breaker 3 retracts back into the housing 1, and then the crushed stone is clamped and collected by individual clamping.

[0044] First, gripper 2, then crush: In this gripping-then-crushing operation, the gripping device 2 is first opened towards the stone. Then, the crusher's robotic arm 6 moves to use the gripping device 2 to enclose or partially enclose the stone. After the enclosing action is completed, the crushing hammer 3 is placed against the stone located within the gripping device 2 to crush it, preventing the stone from slipping during crushing. This method is especially suitable for irregularly shaped stones and smooth-surfaced stones, improving crushing efficiency. After the stone is crushed, the crushing hammer 3 retracts into the housing 1, and the crushed stone is then individually gripped and collected.

[0045] In other embodiments, the breaker hammer 3 can be a crushing block, and the first drive member 4 and the second drive member 5 can be a servo motor or a motor drive member.

[0046] Example 2:

[0047] The crusher with a clamping device in this embodiment is basically the same as that in embodiment 1, except that: a water passage hole is opened on the chisel cavity of the breaker hammer 3, and the chisel cavity is connected to the outside, making it more suitable for underwater operations and for crushing underwater rocks and ores.

[0048] The crusher in this embodiment also includes a deep-water hydraulic system that is matched with the crusher. The deep-water hydraulic system is equipped with a pressure compensation device, which can compensate for the effect of underwater static pressure on the breaker hammer 3.

[0049] This embodiment can solve the problems of slow underwater working speed and low working efficiency of the hydraulic breaker 3 due to underwater static pressure and other issues.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
