Description

Technical Field

[0001] This utility model relates to the field of hydraulic breaker technology, and in particular to a hydraulic breaker specifically designed for mobile crushing plants. Background Technology

[0002] In mobile crushing plants, large stones need to be pre-processed with the help of excavators and hydraulic breakers to break them into smaller pieces. Then, the smaller pieces are crushed by a crusher. Therefore, a special hydraulic breaker for mobile crushing plants is required.

[0003] In existing technologies, when a hydraulic breaker is in operation, the protective cover cannot change with the angle of the chisel rod, resulting in the failure of side protection and the continued flying of rocks, which reduces the protective effect of the cover. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special breaker for mobile crushing plants, which aims to improve the problem that when the breaker is in operation, the protective cover cannot change with the angle of the chisel rod, resulting in the failure of side protection and the occurrence of flying stones, thus reducing the protective effect of the protective cover.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile crushing plant-specific breaker hammer, comprising a breaker hammer body and a protective cover, wherein a mounting plate is fixedly connected to the bottom of the breaker hammer body, and a protective component is installed at the bottom of the mounting plate, the protective component comprising multiple sliding rods, the outer walls of the multiple sliding rods being evenly slidably connected to the inside of the mounting plate, a connecting block being fixedly connected to the bottom of the sliding rod, a rotating ball being fixedly connected to the bottom of the connecting block, the outer wall of the rotating ball being rotatably connected to the inside of the protective cover, a compression spring being fixedly connected to the top of the connecting block, one end of the compression spring being fixedly connected to the bottom of the mounting plate, the compression spring being respectively fitted onto the outer wall of the sliding rod, a limit squeezing block being fixedly connected to the top of the sliding rod, and a dust suppression component being installed on the outer wall of the mounting plate.

[0006] By adopting the above technical solution, when the hydraulic breaker is in operation, the protective cover contacts the surface of the large rock to be broken. The reaction force of the rock causes the sliding rod to move in opposite directions, and the compression spring is compressed. Through the cooperation of the rotating ball and the protective cover, not only can the rock fragments be effectively prevented from splashing during the operation of the hydraulic breaker, avoiding safety hazards such as personnel injury and equipment damage, but the rotating ball can also rotate flexibly, which can well adapt to various angles when the chisel is in operation, improving the protective effect and providing a safer environment for the crushing operation. This also improves the problem that the protective cover cannot change with the angle of the chisel, resulting in the failure of side protection and the occurrence of rock fragments, thus reducing the protective effect of the protective cover.

[0007] Preferably, the dust suppression component includes an annular tube, with connecting pipes uniformly fixedly connected to the outer wall of the annular tube, and a hollow sphere fixedly connected to one end of the connecting pipe, with water outlet holes uniformly opened inside the hollow sphere.

[0008] Preferably, a support column is fixedly connected to one side of the breaker body, a water pump is fixedly connected to one side of the support column, a delivery pipe is fixedly connected to the output end of the water pump, one end of the delivery pipe is fixedly connected to the top of the annular pipe, and a water inlet pipe is fixedly connected to the input end of the water pump.

[0009] Preferably, a sleeve is uniformly fixedly connected to the outer wall of the breaker body, and a trigger switch is installed on the top of the sleeve.

[0010] Preferably, the outer wall of the limiting compression block is slidably connected to the inner wall of the sleeve, and the limiting compression block and the trigger switch are on the same vertical line.

[0011] Preferably, a chisel is fixedly connected to the bottom of the mounting plate, and the outer wall of the chisel is slidably connected to the inner wall of the protective cover.

[0012] Preferably, the top of the breaker body is symmetrically fixedly connected with mounting blocks, and the interior of each of the two mounting blocks is symmetrically provided with mounting holes.

[0013] Preferably, the trigger switch and the water pump are electrically connected to the control system in the excavator, and the control system is used for signal transmission to the trigger switch and operation control of the water pump.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when the breaker is in operation, the protective cover comes into contact with the surface of the large rock to be broken. The reaction force of the rock causes the sliding rod to move in opposite directions, and the compression spring is compressed. Through the cooperation of the rotating ball and the protective cover, not only can the rock be effectively prevented from splashing during the operation of the breaker, avoiding safety hazards such as personal injury and equipment damage, but the rotating ball can also rotate flexibly, which can adapt well to various angles when the chisel is in operation, improving the protective effect and providing a safer environment for the crushing operation.

[0015] 2. In this utility model, when the protective cover contacts the stone and pushes the sliding rod upward, the limiting extrusion block slides along the inner wall of the sleeve. When the limiting extrusion block moves up to contact the trigger switch, the trigger switch transmits an electrical signal to the excavator control system. After receiving the signal, the control system immediately starts the water pump. After the water source is pressurized by the water pump, it sprays out a mist of water through the water outlet, which fully covers the chisel working area and quickly suppresses the spread of dust.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-5 This utility model provides an embodiment of a mobile crushing plant-specific breaker hammer, comprising a breaker hammer body 1 and a protective cover 2. A mounting plate 201 is fixedly connected to the bottom of the breaker hammer body 1. A protective assembly is installed at the bottom of the mounting plate 201. The protective assembly includes multiple sliding rods 202, the outer walls of which are evenly slidably connected to the interior of the mounting plate 201. A connecting block 203 is fixedly connected to the bottom of each sliding rod 202. A rotating ball 204 is fixedly connected to the bottom of each connecting block 203. The outer wall of the rotating ball 204 is rotatably connected to the interior of the protective cover 2. A compression spring 205 is fixedly connected to the top of the connecting block 203. One end of the compression spring 205 is fixedly connected to the bottom of the mounting plate 201. The compression springs 205 are respectively fitted onto the outer walls of the sliding rods 202. A limiting compression block 206 is fixedly connected to the top of each sliding rod 202. A dust suppression assembly is installed on the outer wall of the mounting plate 201.

[0020] Specifically, when the breaker body 1 is in operation, the protective cover 2 first contacts the surface of the large stone to be broken. The stone generates an upward reaction force on the protective cover 2. This force is transmitted through the protective cover 2 to the rotating ball 204 inside, which drives the connecting block 203 fixed at the top of the rotating ball 204 to move upward. The connecting block 203 slides upward along the multiple sliding rods 202 that are evenly connected inside the mounting plate 201, while compressing the compression spring 205. When the working angle of the chisel 6 is adjusted, the rotating ball 204 can rotate flexibly inside the protective cover 2, driving the protective cover 2 to adjust the angle synchronously, always keeping it in contact with the surface of the stone, ensuring that the protection range covers the working area of ​​the chisel 6, and preventing the stone fragments from splashing out from the gaps. Meanwhile, the elastic deformation of the compression spring 205 can buffer the impact force of the stone, reducing the impact force transmitted to the breaker body 1 and the mounting plate 201, and reducing component wear. When the breaker moves to the next working point, and the protective cover 2 is detached from the stone and no longer subject to external force, the compression spring 205 releases its elastic potential energy, pushing the connecting block 203, the rotating ball 204 and the protective cover 2 to reset downwards and return to the initial protective position. The limiting compression block 206 can prevent the sliding rod 202 from falling out of the mounting plate 201, ensuring the stable operation of the protective components. The dust suppression components can reduce the dispersion of dust.

[0021] Reference Figures 1-5 The dust suppression assembly includes an annular pipe 3, with connecting pipes 301 uniformly fixedly connected to the outer wall of the annular pipe 3. A hollow ball 302 is fixedly connected to one end of the connecting pipe 301, and water outlet holes 303 are uniformly opened inside the hollow ball 302. A support column 4 is fixedly connected to one side of the breaker body 1, and a water pump 401 is fixedly connected to one side of the support column 4. A conveying pipe 402 is fixedly connected to the output end of the water pump 401, and one end of the conveying pipe 402 is fixedly connected to the top of the annular pipe 3. A water inlet pipe 403 is fixedly connected to the input end of the water pump 401. A sleeve 5 is uniformly fixedly connected to the outer wall of the breaker body 1, and a trigger switch 501 is installed on the top of the sleeve 5. The outer wall of the limiting extrusion block 206 is slidably connected to the inner wall of the sleeve 5, and the limiting extrusion block 206 and the trigger switch 501 are on the same vertical line. The trigger switch 501 and the water pump 401 are electrically connected to the control system in the excavator. The control system is used for signal transmission to the trigger switch 501 and operation control of the water pump 401.

[0022] Specifically, when the protective cover 2 contacts the stone and pushes the sliding rod 202 upward, the limiting compression block 206 slides along the inner wall of the sleeve 5. Since the limiting compression block 206 and the trigger switch 501 at the top of the sleeve 5 are on the same vertical line, when the limiting compression block 206 moves upward to contact the trigger switch 501, the trigger switch 501 transmits an electrical signal to the excavator control system. After receiving the signal, the control system immediately starts the water pump 401. The water pump 401 draws water from the excavator's own water source through the inlet pipe 403 at the input end. The water source is then pumped by the water pump 401. After pressurization, the water is delivered to the annular pipe 3 through the output pipe 402. The connecting pipe 301 guides the water into the hollow ball 302. Finally, a mist of water is sprayed out from the water outlet 303 evenly opened inside the hollow ball 302, which fully covers the working area of ​​the drill rod 6 and quickly suppresses the spread of dust. As long as one of the limit squeezing blocks 206 squeezes the trigger switch 501, the water pump 401 will be turned on. The water pump 401 is turned off by the control system in the excavator. The trigger switch 501 is model D2VW-5L2A-1M.

[0023] Reference Figures 2-3 A drill rod 6 is fixedly connected to the bottom of the mounting plate 201, and the outer wall of the drill rod 6 is slidably connected to the inner wall of the protective cover 2.

[0024] Specifically, the inner wall of the protective cover 2 is made of soft silicone. When the breaker drives the chisel 6 to perform up-and-down reciprocating crushing action, the chisel 6 can slide smoothly along the inner wall of the protective cover 2. The soft silicone material will not hinder the working stroke of the chisel 6, and can also adapt to the slight angular deviation of the chisel 6 during operation, avoiding hard contact that could scratch the outer wall of the chisel 6. At the same time, the protective cover 2 always covers the working end of the chisel 6, ensuring that the protection against stone fragments is uninterrupted, and achieving smooth coordination between protection and operation.

[0025] Reference Figures 1-3 , Figure 5 The top of the breaker body 1 is symmetrically fixedly connected with mounting blocks 7, and the interior of the two mounting blocks 7 is symmetrically provided with mounting holes 701.

[0026] Specifically, when installing the hydraulic breaker body 1, align the hydraulic connection component of the excavator with the mounting block 7, pass the high-strength bolts through the mounting hole 701 and tighten them to achieve a firm fixation between the hydraulic breaker body 1 and the excavator; the hydraulic system of the excavator provides power to the hydraulic breaker, driving the chisel 6 to impact the rocks, while the walking mechanism of the excavator enables the hydraulic breaker to move flexibly.

[0027] Working principle: During installation, the excavator's hydraulic connection components are aligned with the mounting block 7, and high-strength bolts are tightened through the mounting holes 701. The hydraulic system of the excavator powers the chisel 6 to impact the rocks, and the movement of the breaker hammer is achieved with the help of the excavator's traveling mechanism. When the breaker hammer body 1 is in operation, the protective cover 2 first contacts the surface of the large rock to be broken. The reaction force of the rock is transmitted through the protective cover 2 to the rotating ball 204 inside, which drives the connecting block 203 at the top of the rotating ball 204 to move along the multiple sliding rods 202 inside the mounting plate 201. As the chisel rod 6 slides upward, it simultaneously compresses the compression spring 205. When the chisel rod 6 adjusts the working angle, the rotating ball 204 rotates flexibly inside the protective cover 2, causing the protective cover 2 to adjust the angle synchronously. When the protective cover 2 pushes the sliding rod 202 upward, the limiting compression block 206 slides along the inner wall of the sleeve 5. After contacting the top of the sleeve 5 and triggering the switch 501, the signal is transmitted to the excavator control system to start the water pump 401. The water pump 401 draws water from the source through the water inlet pipe 403, pressurizes it, and sends it to the annular pipe 3 through the delivery pipe 402. Then, it sprays out a mist of water from the water outlet 303.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
