[0053] Example 2

[0054] Reference Figures 1-3 This embodiment differs from the first embodiment in that: an open-pit mine electric shovel decontamination device includes the dust suppression mechanism M as described above, comprising,

[0055] The main component 100 includes a bucket section 101, a baffle 102 disposed at the bottom of the bucket section 101, and a support arm 103 disposed on one side of the bucket section 101; the anti-stick component 200 includes a lifting assembly 201, a connecting rod assembly 202 disposed between the lifting assembly 201 and the baffle 102, and a limiting member 203 disposed on the inner wall of the bucket section 101; wherein the lifting assembly 201 is slidably disposed inside the bucket section 101.

[0056] A baffle 102 is rotatably mounted at the bottom of the bucket section 101. A support arm 103 is connected to one side of the bucket section 101. The equipment uses the support arm 103 to drive the bucket section 101 to scoop up materials. When the materials are moved to the unloading area, the baffle 102 rotates to open the bottom of the bucket section 101 for unloading. The lifting assembly 201 is slidably mounted inside the bucket section 101 by conforming to the inner wall of the bucket section 101. A connecting assembly connects the baffle 102 and the lifting assembly 201. When the baffle 102 rotates open, the lifting assembly 201 is driven to slide inside the bucket section 101 via the connecting rod assembly 202. When the lifting assembly 201 slides, it scrapes the inner side of the bucket section 101. The material is prevented from sticking to the inner wall of the bucket section 101. On the other hand, the material is quickly dropped from the bucket section 101 by the scraping action of the lifting component 201. The limiting member 203 is cylindrical, which restricts the range of motion of the lifting component 201 while preventing the material from sticking to its surface. There are four limiting members 203 at the top and bottom of the inner wall of the bucket section 101. The four limiting members 203 are arranged in pairs on the left and right inner walls of the bucket section 101. The limiting member 203 located at the bottom inner side of the bucket section 101 is above the baffle 102, and the limiting member 203 located at the top inner side of the bucket section 101 is above the lifting component 201.

[0057] Specifically, the lifting assembly 201 includes a scraping frame 201a, a connecting rod 201b disposed on the scraping frame 201a, and a waist-shaped groove 201c formed on the connecting rod 201b; wherein, the scraping frame 201a is slidably disposed inside the bucket part 101, the waist-shaped groove 201c corresponds to the connecting rod assembly 202, the scraping frame 201a is "U"-shaped, and its length and width are the same as the inner side of the bucket part 101, so that the periphery of the scraping frame 201a can fit against the inner wall of the bucket part 101, and then slide and connect with the inner side of the bucket part 101. The middle part of the scraping frame 201a is located inside the bucket part 101. A connecting rod 201b is fixedly provided, and the position of the connecting rod 201b is on the same line as the rotation direction of the baffle 102. A waist-shaped groove 201c is opened in the connecting rod 201b. The scraping frame 201a is connected to the connecting rod assembly 202 through the waist-shaped groove 201c. When the baffle 102 rotates, it drives the connecting rod assembly 202 to move in the waist-shaped groove 201c, and then drives the scraping frame 201a to move in the lifting part. The scraping frame 201a moves to scrape the material inside the bucket part 101, so that the material can fall quickly, while preventing the material from sticking to the inside of the bucket part 101.

[0058] Furthermore, the connecting rod assembly 202 includes a connecting seat 202a, a through groove 202b formed in the connecting seat 202a, and a rotating member 202c disposed on the connecting seat 202a; wherein, the connecting seat 202a is disposed on the top of the baffle 102 and fixedly disposed on the top of the baffle 102, the connecting seat 202a is disposed below and close to the connecting rod 201b, the connecting seat 202a has a through groove 202b, the connecting seat 202a is rotatably connected to the rotating member 202c through the through groove 202b, the other end of the rotating member is connected to the connecting rod 201b, when the baffle 102 rotates, the rotating member is driven to rotate through the connecting seat 202a, the end of the rotating member moves in the waist-shaped groove 201c, and then drives the scraping frame 201a to slide through the connecting member rod.

[0059] Furthermore, the rotating component 202c includes a diagonal rod 202c-1, connecting posts 202c-2 and positioning posts 202c-3 located at both ends of the diagonal rod 202c-1; wherein, the positioning post 202c-3 is inserted into the through groove 202b, the diagonal rod 202c-1 is connected to the connecting seat 202a through the positioning post 202c-3, the waist-shaped groove 201c corresponds to the connecting post 202c-2, the end of the diagonal rod 202c-1 is connected to the connecting rod 201b through the connecting post 202c-2, and a set of diagonal rods 202c-1 is provided on each side of the connecting rod 201b, and the top ends of the two sets of diagonal rods 202c-1 are fixed together. A connecting post 202c-2 is fixedly connected and is located in the waist-shaped groove 201c. A positioning post 202c-3 is fixedly connected to the bottom end of the two sets of diagonal rods 202c-1. The positioning post 202c-3 is located in the through groove 202b. The bottom end of the diagonal rod 202c-1 is rotatably connected to the connecting seat 202a through the positioning post 202c-3. The top end of the diagonal rod 202c-1 is slidably connected to the connecting rod 201b through the connecting post 202c-2. When the baffle 102 rotates, it pulls the diagonal rod 202c-1 to rotate. The diagonal rod 202c-1 pulls the scraping frame 201a to move through the connecting post 202c-2.

[0060] The rest of the structure is the same as in Example 1.

[0061] Operation process: When the baffle 102 closes the bottom of the bucket part 101, the connecting column 202c-2 is located at the end of the waist groove 201c away from the connecting seat 202a, the diagonal bar 202c-1 is in an inclined state with its top away from the connecting seat 202a, and the limiting member 203 located at the top of the inner side of the bucket part 101 limits the scraping frame 201a;

[0062] When the baffle 102 opens the bottom of the bucket 101 to unload material, the baffle 102 pulls the inclined rod 202c-1 to rotate through the connecting seat 202a. When the inclined rod 202c-1 rotates, it pulls the scraping frame 201a downward through the connecting column 202c-2. At this time, the connecting column 202c-2 slides in the connecting rod 201b. The limiting member 203 located at the bottom of the inner side of the bucket 101 limits the scraping frame 201a to prevent the scraping frame 201a from detaching from the bucket 101. The movement of the scraping frame 201a scrapes the material off the inner wall of the bucket 101, preventing the material from sticking to the inner wall of the bucket 101. At the same time, the scraping of the scraping frame 201a makes the material discharge from the bucket 101 faster.

[0063] When the baffle 102 is reset after the material discharge is completed, the inclined rod 202c-1 rotates again, causing the connecting column 202c-2 to slide on the connecting rod 201b, which in turn pushes the scraping frame 201a to rise and reset, so as to prepare for the next scraping operation;

[0064] The baffle 102 drives the scraping frame 201a, which automatically scrapes the material in the bucket 101 during unloading, preventing the material from sticking to the inner wall of the bucket 101 and enabling unloading to be completed quickly without shaking the bucket 101, making operation more convenient. The scraping frame 201a can also automatically reset.

[0065] Example 3

[0066] Reference Figures 1-9 This embodiment differs from the above embodiments in that it also includes a follower component 300, which is disposed on the support arm 103;

[0067] A retractable component 400 is located inside the follower component 300 and can extend and retract following the baffle 102 via the follower component 300.

[0068] Switching component 500; it is disposed in follower component 300;

[0069] A moving component 600 is disposed between the following component 300 and the retracting component 400.

[0070] After the follower component 300 slides along the baffle 102, it can trigger the switch component 500 to open and close, and the moving component 600 can move along with the retracting component 400.

[0071] The follower component 300 includes two sets of mounting components 301, a sliding component 302 disposed in the mounting components 301, and a connecting component 303 disposed between the sliding component 302 and the baffle 102. The mounting components 301 are disposed on both sides of the support arm 103, and the top of the sliding component 302 is provided with a shrinking component 400. The two sets of mounting components 301 are respectively disposed on both sides of the support arm 103. The device is installed by the mounting components 301. When the baffle 102 rotates to unload, a lot of dust is generated in the unloading area. The connecting component 303 pushes the sliding component 302 to slide out of the mounting components 301, so that the sliding component 302 drives the shrinking component 400 to rise. After the shrinking component 400 rises, it sprays horizontally into the air in the unloading area to reduce the dispersion of dust in the air in the unloading area.

[0072] Specifically, the mounting component 301 includes a U-shaped frame 301a sleeved on the support arm 103 and a fixing cylinder 301b disposed on one side of the U-shaped frame 301a; wherein, the sliding component 302 is disposed in the fixing cylinder 301b, the U-shaped frame 301a is fixed to the support arm 103 by bolts or welding, the openings of the two sets of U-shaped frames 301a are disposed opposite each other on both sides of the support arm 103, and the fixing cylinder 301b is fixedly connected to the side of the two sets of U-shaped frames 301a that is far apart from each other, and the fixing cylinder 301b is fixed to the support arm 103 by the U-shaped frame 301a.

[0073] Furthermore, the sliding assembly 302 includes a guide cylinder 302a, a guide plate 302b fixedly mounted on the top of the guide cylinder 302a, and a lifting rod 302c slidably disposed in the guide plate 302b; wherein, the guide cylinder 302a is fixedly mounted on the inner wall of the fixed cylinder 301b, the connecting assembly 303 is disposed at the bottom of the lifting rod 302c, the retraction component 400 is disposed at the top of the lifting rod 302c, and a circular groove is opened in the middle of the guide plate 302b, through which the lifting rod 302c slidably disposed in the guide plate 302b, and the lifting rod 302c is disposed in the fixed cylinder 301b. When the lifting rod 302c slides to its maximum stroke, it will not detach from the guide plate 302b. The guide plate 302b guides and limits the sliding of the lifting rod 302c, so that the lifting rod 302c slides stably longitudinally in the fixed cylinder 301b without tilting during the sliding process. When the lifting rod 302c is in the initial state, the retracting component 400 is also located in the fixed cylinder 301b. The lifting rod 302c slides out of the fixed cylinder 301b, causing the retracting component 400 to extend out of the top of the fixed cylinder 301b and spray water into the air to achieve the effect of dust reduction in the unloading area.

[0074] Furthermore, the connecting assembly 303 includes a short rod 303a located at the bottom of the lifting rod 302c, a spring 303b located outside the short rod 303a, a guide plate 303c located at the bottom of the fixed cylinder 301b, and a cable 303d located between the baffle 102 and the short rod 303a; a switch component 500 is provided between the lifting rod 302c and the short rod 303a, the diameter of the short rod 303a is smaller than the diameter of the lifting rod 302c, the cable 303d is fixedly connected to the bottom of the short rod 303a, the guide plate 303c is fixedly provided at the bottom of the fixed cylinder 301b, and a guide cylinder is provided in the middle of the guide plate 303c. The diameter is smaller than that of the short rod 303a. The end of the cable 303d passes through the guide tube and is fixedly connected to the bottom of the baffle 102. The guide tube limits and guides the movement of the cable 303d. A spring 303b is sleeved on the outside of the short rod 303a. The top of the spring 303b abuts against the bottom of the lifting rod 302c, and its bottom abuts against the top of the guide plate 303c. When the baffle 102 rotates, the cable 303d is released, and the spring 303b abuts against the lifting rod 302c, pushing it to rise. The rise of the lifting rod 302c drives the retraction component 400 to extend out of the fixed tube 301b. At this time, the retraction component 400 is activated to spray dust suppression in the unloading area.

[0075] Furthermore, the retractable component 400 includes a hinge seat 401, a rotating rod 402 disposed on the hinge seat 401, and a positioning member 403 disposed on the fixed cylinder 301b. The hinge seat 401 is disposed on the lifting rod 302c, and multiple sets of hinge seats 401 are fixedly disposed on the outer side of the top of the lifting rod 302c. The rotating rod 402 is rotatably connected to each of the multiple sets of hinge seats 401. Multiple sets of positioning members 403 are fixedly disposed on the inner wall of the fixed cylinder 301b, and the number of positioning members 403 corresponds to the number of hinge seats 401. The rotating rod 402 is sleeved on the positioning member 403, and the positioning member 403 limits and guides the rotating rod 402. When the lifting rod 302c rises, it drives the multiple sets of rotating rods 402 to move synchronously through the hinge seat 401. When the rotating rod 402 extends out of the fixed cylinder 301b, the rotating rod 402 is limited and unfolded by the positioning member 403, thereby increasing the spray range.

[0076] Furthermore, the rotating rod 402 has a waist-shaped groove 402a and a nozzle 402b at its top; the positioning member 403 includes a fixing seat 403a on the inner wall of the fixing cylinder 301b and a fixing post 403b on the fixing seat 403a; wherein, the rotating rod 402 is sleeved with the fixing post 403b through the waist-shaped groove 402a, and the top of the inner wall of the fixing cylinder 301b is provided with multiple sets of fixing seats 403a through the moving member 600, and each set of fixing seats 403a is fixedly provided with a fixing post 403b, the rotating rod 402 has a waist-shaped groove 402a corresponding to the fixing post 403b, and the fixing post 402b is provided with a fixing post 403b. A nozzle 402b is fixedly installed at the top of 3b. The nozzle 402b is connected to the water pump through a hose. When the lifting rod 302c rises, the rotating rod 402 slides outside the fixed column 403b through the waist-shaped groove 402a. The limiting position of the fixed column 403b causes the rotating rod 402 to rotate around the connection with the fixed seat 403a, causing multiple sets of nozzles 402b to move away from the lifting rod 302c and spread out, thereby increasing the spray range. At the same time, the nozzles 402b are driven to rise by the lifting rod 302c, increasing the spray height. The maximum rotation angle of the rotating rod 402 is 70 degrees, so that after the rotating rod 402 rotates, the nozzles 402b are still in a high position.

[0077] It also includes a switch component 500; which includes a mounting bracket 501, a push switch 502 disposed on the mounting bracket 501, a movable sleeve 503 disposed outside the push switch 502, and a limiting member 504 disposed between the movable sleeve 503 and the mounting bracket 501; wherein, the mounting bracket 501 is disposed between the lifting rod 302c and the short rod 303a, the lifting rod 302c is rotatably mounted on the short rod 303a. A push-button switch 502 is mounted on the mounting bracket 501. The push-button switch 502 is electrically connected to the water pump, thereby controlling the start and stop of the water pump. A movable sleeve 503 is slidably connected to the mounting bracket 501 via a limiting member 504. The movable sleeve 503 is sleeved on the outside of the push-button switch 502, and the inner wall of the movable sleeve 503 is in contact with the outer side of the push-button switch 502, allowing the movable sleeve 503 to slide laterally. The top of the movable sleeve 503 is provided with a sloping surface L2, which guides... The bottom end of the guide cylinder 302a is provided with an inclined surface S corresponding to the inclined surface L. The distance between the inner wall of the fixed cylinder 301b and the outer side of the lifting rod 302c is less than the distance between the end of the push switch 502 and the outer side of the mounting bracket 501. When the push switch 502 is located away from the guide cylinder 302a, it is in a relaxed state and the water pump is not started. When the lifting rod 302c rises, it drives the push switch 502 to rise synchronously through the mounting bracket 501. When the push switch 502 rises, the inclined surface L of the moving sleeve 503 abuts against the inclined surface S of the guide cylinder 302a and slides in the first direction, which is the direction closer to the fixed bracket. When the moving sleeve 503 moves to the inner side of the guide cylinder 302a, the moving sleeve 503 slides and squeezes the push switch 502. The push switch 502 is squeezed and turns on the water pump, so that the water pump works to deliver water to the nozzle 402b. When the lifting rod 302c rises, the moving sleeve 503 always abuts against the inner wall of the guide cylinder 302a.

[0078] Specifically, the limiting member 504 includes a fixed plate 504a, a limiting post 504b disposed on the top of the movable sleeve 503, and a guide groove 504c opened on the fixed plate 504a; wherein, the fixed plate 504a is disposed on the outside of the mounting frame 501, the fixed plate 504a is sleeved with the limiting post 504b through the guide groove 504c, the outside of the mounting frame 501 is fixedly disposed on the fixed plate 504a, the mounting frame 501 has a guide groove 504c opened in it, the top of the movable sleeve 503 is fixedly disposed with the limiting post 504b, the limiting post 504b is slidably disposed in the guide groove 504c, so that the movable sleeve 503 is limited and guided to slide by the limiting post 504b.

[0079] It also includes a movable component 600, which includes a guide post 601, a closure 602 located at the top of the lifting rod 302c, an annular groove 301c formed on the fixed cylinder 301b, and a ring 603 located in the annular groove 301c; wherein, the guide post 601 is located on the inner wall of the guide cylinder 302a, and a spiral groove 302d is formed on the outer side of the lifting rod 302c, the guide post 601 extends into the spiral groove 302d, the guide post 601 is fixedly located at the upper inner side of the guide cylinder 302a, and the spiral groove 302d is formed on the outer side of the lifting rod 302c. When the lifting rod 302c is not raised, the guide post 601 is located at the top end of the spiral groove 302d. When the lifting rod 302c is not raised, the guide post 601 is located at the top end of the spiral groove 302d. When 302c rises, the guide post 601 cooperates with the spiral groove 302d to guide the lifting rod 302c, causing the lifting rod 302c to rotate during the rising process. The rotation of the lifting rod 302c makes the water sprayed from the nozzle 402b more even. The top of the lifting rod 302c is fixedly provided with a sealing member 602. In this embodiment, the inner wall of the fixed cylinder 301b is also provided with an annular groove 301c. A circular ring 603 is rotatably connected in the annular groove 301c. Multiple sets of fixed seats 403a are fixedly provided inside the circular ring 603, so that the fixed seats 403a can rotate along with the lifting rod 302c during the rising and rotating process, so that the guide post 601 can still guide the rotating rod 402.

[0080] Specifically, the sealing component 602 includes a fixed rod 602a located at the top of the lifting rod 302c and a circular plate 602b located at the top of the fixed rod 602a. The fixed rod 602a is fixedly installed at the top of the lifting rod 302c, and the circular plate 602b is fixedly installed at the top of the fixed rod 602a. The diameter of the circular plate 602b is the same as the inner diameter of the fixed tube. When the rotating rod 402 is stored in the fixed tube, the circular plate 602b is driven to seal the top of the fixed tube, so that when the nozzle 402b is not in use, dust is reduced from entering the fixed tube, and the nozzle 402b is prevented from being blocked by dust.

[0081] The rest of the structure is the same as in Example 2.

[0082] Operation process: During the process of the electric shovel scooping up the ore, the baffle 102 and the support arm 103 will not move relative to each other. The baffle 102 is always in the closed bucket part 101 bottom state. The cable 303d is pulled and is in a taut state. The lifting rod 302c is at the corresponding position to the guide cylinder 302a. The spring 303b is squeezed by the lifting rod 302c and is in a contracted state. Multiple sets of rotating rods 402 are driven by the lifting rod 302c and stored in the fixed cylinder 301b. At this time, the fixed column 403b is located at the top of the waist-shaped groove 402a. The push switch 502 is located below the guide cylinder 302a. At this time, the push switch 502 is in the relaxed state and the water pump is not turned on. The lifting rod 302c is located inside the guide cylinder 302a. The guide column 601 is located at the top of the spiral groove 302d. The circular plate 602b closes the top of the fixed cylinder 301b.

[0083] When the electric shovel unloads material in the unloading area, the baffle 102 rotates to open the bottom of the bucket 101, allowing the material to be poured out. The rotation of the baffle 102 relaxes the cable 303d, and the spring 303b loses its compressive force, pushing the lifting rod 302c to rise. During the rise of the lifting rod 302c, the guide plate 302b guides and limits it. When the lifting rod 302c rises, it drives multiple sets of rotating rods 402 to move out of the fixed cylinder 301b. During the rise of the rotating rods 402, they slide outside the fixed column 403b. The fixed column 403b limits the rotating rods 402, causing them to rotate and drive multiple sets of nozzles 402b to spread out. The water pump delivers spray water to the nozzles 402b, and the nozzles 402b spray to suppress dust in the surrounding environment.

[0084] When the material is unloaded and the lifting rod 302c rises, the lifting rod 302c drives the push switch 502 to rise through the mounting bracket 501. The inclined surface 2L of the moving sleeve 503 abuts against the inclined surface 1S of the guide cylinder 302a, causing the moving sleeve 503 to slide in the first direction. After the moving sleeve 503 slides, it abuts against the push switch 502. When the end of the moving sleeve 503 abuts against the inner wall of the positioning cylinder, the push switch 502 is pressed, and the water pump is turned on. At this time, the nozzle 402b has been driven out of the fixed cylinder 301b by the lifting rod 302c. The water pump delivers spray water to the nozzle 402b, so that the nozzle 402b sprays water on the environment to achieve the dust suppression effect. During the process of the lifting rod 302c rising, the moving sleeve 503 always abuts against the inner wall of the guide cylinder 302a.

[0085] At this time, the guide column 601 cooperates with the spiral groove 302d, so that the lifting rod 302c is guided to rotate by the guide column 601 during the upward process. The fixed seat 403a is rotatably connected to the fixed cylinder 301b through the ring 603. The rotation of the lifting rod 302c drives the ring 603 to rotate synchronously, so that the fixed column 403b can still guide the rotating rod 402 during the upward rotation. The lifting rod 302c drives multiple sets of nozzles 402b to rotate through the rotating rod 402. The nozzles 402b spray while rotating. At the same time, the rise of the lifting rod 302c drives the circular plate 602b to rise through the fixed rod 602a, so that the circular plate 602b will not block the nozzles 402b from extending.

[0086] When the electric shovel finishes unloading and the baffle 102 rotates to its reset position, the cable 303d is driven to pull the short rod 303a. The short rod 303a drives the lifting rod 302c to slide downwards, and the spring 303b is compressed. At the same time, multiple sets of rotating rods 402 are driven to slide downwards by the lifting rod 302c. Due to the limitation of the fixed column 403b, the rotating rods 402 rotate and move closer to the lifting rod 302c, so that multiple sets of rotating rods 402 are stored in the fixed cylinder 301b. At the same time, when the lifting rod 302c slides into the fixed cylinder 301b, the push switch 502 is driven to descend synchronously. When the moving sleeve 503 moves away from the guide cylinder 302a, the push switch 502 automatically resets, the water pump is turned off, and the nozzle 402b stops spraying. When the lifting rod 302c descends to its reset position and the nozzle 402b is stored in the fixed cylinder 301b, the circular plate 602b closes the top of the fixed cylinder 301b again.

[0087] When the electric shovel generates a lot of smoke and dust in the unloading area, multiple sets of nozzles 402b automatically extend to spray and suppress dust in the unloading area. The multiple sets of nozzles 402b can extend within a certain range, increasing the spray range, improving the dust suppression effect, and reducing the impact of smoke and dust on human health during electric shovel unloading.

[0088] The water pump is controlled by the push switch 502 and automatically turns on only when the electric shovel is unloading material to supply water to the nozzle 402b to achieve the dust suppression effect. After unloading is completed, it automatically stops. Through the automatic start and stop of the water pump, the device is ensured to spray dust suppression only in the unloading area, reducing the consumption of spray water.

[0089] As the lifting rod 302c rotates during its ascent, the nozzle 402b rotates around the lifting rod 302c during spraying, resulting in a wider spray range and more uniform spraying, further improving the dust suppression effect. At the same time, when the nozzle 402b is stored in the fixed cylinder 301b, the circular plate 602b seals the top of the fixed cylinder 301b, preventing dust from entering the fixed cylinder 301b and clogging the nozzle 402b.
