The rock splitter, also known as a splitting machine, is a machine used to split materials. It is widely used in construction, decoration, engineering construction, and ore mining. The rock splitter consists of two main parts: a hydraulic power station and a splitting gun. The rock splitter is driven by ultra-high pressure oil output from the pump station to generate a huge thrust, which is then mechanically amplified to cause the object to be split to crack in a predetermined direction.

[0003] However, rock splitters usually require manual handling for transport and operation, which is laborious, inflexible, and inconvenient. Furthermore, the rock splitter generates a large reaction force during operation, making it difficult for operators to hold the machine, resulting in poor stability during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6As shown, a crushing device for open-pit mining includes a trolley 1, on which a buffer structure 2 is installed. The buffer structure 2 includes a sliding sleeve 202. A sliding rod 203 is slidably connected inside the sliding sleeve 202. A mounting plate 204 is fixedly connected to the top end of the sliding rod 203. A fixing structure 4 is installed on the mounting plate 204. The fixing structure 4 includes a lead screw 403. The lead screw 403 is rotatably connected to the mounting plate 204. Two second sliders 401 are threadedly connected to the lead screw 403. The two second sliders 401 are connected to the mounting plate 204. The two second sliders 401 are connected by a sliding connection. Each end of one of the two second sliders 401 is fixedly connected to a clamp 402. The two clamps 402 clamp the same splitter 7. A through hole 8 is provided on the bottom plate of the trolley 1. The end of the splitter 7 passes through the through hole 8. The threads at both ends of the lead screw 403 are opposite. The two second sliders 401 and the two clamps 402 are symmetrically arranged. The ends of the clamps 402 have an arc-shaped structure. A support structure 9 is installed at the bottom of the trolley 1. The splitter 7 is moved onto the trolley 1, and the end of the splitter 7 passes through the through hole 8. Then, the rotating rod 404 is rotated. 04 drives the lead screw 403 to rotate. Since the threads at both ends of the lead screw 403 are opposite, the lead screw 403 drives the two second sliders 401 to move towards the middle of the lead screw 403. The lead screw 403 continues to rotate until the two second sliders 401 press against the splitter 7 from both sides towards the middle, thereby quickly fixing the splitter 7. This makes it easier to move the splitter 7 by the trolley 1. During use, the fixing structure 4 clamps and fixes the splitter 7, increasing its stability. It is also easier and less labor-intensive to use, flexible and convenient, and improves construction efficiency. After the splitter 7 is installed on the trolley 1... Turn on the control switch of the splitter 7 and press down the handle of the splitter 7. The splitter 7 drives the clamp 402 to move downward. The movement of the clamp 402 drives the second slider 401 and the mounting plate 204 to move downward. The movement of the mounting plate 204 drives the slide rod 203 to slide into the sliding sleeve 202. The slide rod 203 drives the stop block 207 to press down and retract the spring 208. Continue to press the handle of the splitter 7 until the end of the splitter 7 passes through the through hole 8 and performs the crushing work on the bottom area of ​​the trolley 1. The buffer structure 2 drives the splitter 7 to slide up and down, making the splitter 7 more flexible and labor-saving during use.

[0025] As a technical optimization of this utility model, a rubber pad 405 is installed on the side of the clamp 402 facing the splitter 7. The rubber pad 405 abuts against the splitter 7, and a rotating rod 404 is slidably connected to the end of the lead screw 403. The rubber pad 405 can increase the friction between the clamp 402 and the splitter 7, so that the two clamps 402 clamp the splitter 7 more closely and firmly.

[0026] As a technical optimization of this utility model, the bottom end of the slide rod 203 is fixedly connected to a stop block 207, the bottom end of the stop block 207 abuts against a spring 208, and the bottom end of the spring 208 is fixedly connected inside the sliding sleeve 202. The setting of the spring 208 has a buffering effect on the downward movement of the splitter 7, making the splitter 7 more stable during operation. When the crushing work is completed, the handle of the splitter 7 is no longer pressed down. At this time, the spring 208 loses its resisting force, the spring 208 returns to its original position, and drives the stop block 207 to slide upward. The stop block 207 drives the slide rod 203 and the mounting plate 204 to slide upward. The mounting plate 204 drives the splitter 7 to move upward through the fixing structure 4, so that the end of the splitter 7 no longer contacts the ground.

[0027] As a technical optimization of this utility model, a horizontal plate 3 is fixedly connected to the push rod of the trolley 1, and a fixing sleeve 201 is installed on the horizontal plate 3. The sliding sleeve 202 is fixedly connected to the fixing sleeve 201; the fixing sleeve 201 further fixes the sliding sleeve 202, increasing the stability of the buffer structure 2.

[0028] As a technical optimization of this utility model, the support structure 9 includes a rotating shaft 901. The two sides of the trolley 1 are rotatably connected to the rotating shaft 901, and the same support rod 902 is fixedly connected to both rotating shafts 901. A slot 903 is provided on the side wall of the support rod 902. A connecting block 904 is fixedly connected to the bottom of the trolley 1, and a locking block 905 is slidably connected within the connecting block 904. The locking block 905 engages with the slot 903. The support rod 902 has a "U" shape, and the locking block 905 has an "L" shape. When the splitter 7 is moved to the designated area by the trolley 1, the support rod 902 is pushed, causing the rotating shaft 901 to rotate until the bottom of the support rod 902 touches the ground. The surface is in contact with the ground. Then, push the locking block 905 outward with your foot. The locking block 905 slides on the connecting block 904. Continue pushing the locking block 905 until it engages in the slot 903 on the support rod 902, thereby fixing the support rod 902 and increasing the stability of the trolley 1 when parked. This makes it easier to operate the splitter 7. When it is necessary to move the splitter 7 through the trolley 1, push the locking block 905 towards the middle of the trolley 1 with your foot, so that the locking block 905 is no longer engaged with the slot 903, thereby releasing the fixation of the support rod 902. During the movement of the trolley 1, the support rod 902 is driven to rotate by the rotating shaft 901, so that the support rod 902 no longer contacts the ground and avoids the support rod 902 affecting the movement of the trolley 1.

[0029] As a technical optimization of this utility model, the top of the push rod of the trolley 1 is fixedly connected to a handle 5, the handle 5 is in the shape of a "U" and a rubber sleeve 6 is fitted on the handle 5; the handle 5 is designed to facilitate pushing the trolley 1, and the rubber sleeve 6 can play a role in preventing slippage.

[0030] As a technical optimization of this utility model, the push rod of the trolley 1 is provided with a sliding groove 205. Two first sliders 206 are fixedly connected to the side of the mounting plate 204 facing away from the splitter 7. The first sliders 206 are slidably connected to the sliding groove 205. Both the sliding groove 205 and the first sliders 206 are T-shaped. When the mounting plate 204 moves, the two first sliders 206 fixed on the mounting plate 204 slide in the sliding groove 205. The setting of the first sliders 206 has a guiding effect on the movement of the mounting plate 204, making the movement of the mounting plate 204 more stable, thereby making the splitter 7 more stable and smooth when moving up and down.

[0031] In use, the rock splitter 7 is first moved onto the trolley 1, and the end of the rock splitter 7 is passed through the through hole 8. Then, the rotating rod 404 is rotated, which drives the lead screw 403 to rotate. Since the threads at both ends of the lead screw 403 are opposite, the lead screw 403 drives the two second sliders 401 to move towards the middle of the lead screw 403. The lead screw 403 is continuously rotated until the two second sliders 401 press against the rock splitter 7 from both sides towards the middle, thereby quickly fixing the rock splitter 7. This makes it easier to move the rock splitter 7 by the trolley 1, and it is also convenient to use during the process. The rock splitter 7 is clamped and fixed by the fixing structure 4, which increases the stability of the rock splitter 7, makes it easier and less labor-intensive to use, and improves construction efficiency. After the rock splitter 7 is installed on the trolley 1, the control switch of the rock splitter 7 is turned on, and the handle of the rock splitter 7 is pressed down. The rock splitter 7 drives the clamp 402 to move downward. The movement of the clamp 402 drives the second slider 401 and the mounting plate 204 to move downward. The movement of the mounting plate 204 drives the slide rod 203 to slide into the sliding sleeve 202. The slide rod 203 drives the abutment block 2. 07. The downward contact spring 208 retracts, continuously pressing the handle of the splitter 7 until the end of the splitter 7 penetrates the through hole 8, then performs crushing work on the bottom area of ​​the trolley 1. The spring 208 provides a buffer for the downward movement of the splitter 7, making the splitter 7 more stable during operation. After the crushing work is completed, the downward pressure on the handle of the splitter 7 is stopped. At this time, the spring 208 loses its resistance and returns to its original position, causing the abutment block 207 to slide upward. The abutment block 207 causes the slide rod 203 and the mounting plate 204 to slide upward. The mounting plate 204... The fixed structure 4 drives the rock splitter 7 to move upward, so that the end of the rock splitter 7 is no longer in contact with the ground. Then, the rock splitter 7 can be moved by the trolley 1, which increases the flexibility and comfort of using the rock splitter 7 and improves the construction efficiency. When the mounting plate 204 moves, the two first sliders 206 fixed on the mounting plate 204 slide in the slide groove 205. The setting of the first sliders 206 has a guiding effect on the movement of the mounting plate 204, making the movement of the mounting plate 204 more stable, thus making the rock splitter 7 more stable and smooth when moving up and down.After the rock splitter 7 is moved to the designated area by the trolley 1, push the support rod 902. The support rod 902 drives the rotating shaft 901 to rotate until the bottom end of the support rod 902 touches the ground. Then, push the locking block 905 outward with your foot. The locking block 905 slides on the connecting block 904. Continue pushing the locking block 905 until it engages with the slot 903 on the support rod 902, thus fixing the support rod 902 and increasing the stability of the trolley 1 when parked, thereby facilitating the operation of the rock splitter 7. When it is necessary to move the rock splitter 7 by the trolley 1, push the locking block 905 towards the middle of the trolley 1 with your foot, so that the locking block 905 is no longer engaged with the slot 903, thereby releasing the fixation of the support rod 902. During the movement of the trolley 1, the support rod 902 is rotated by the rotating shaft 901, thus preventing the support rod 902 from touching the ground and avoiding the support rod 902 from affecting the movement of the trolley 1.
