[0043] Example 1

[0044] Reference Figures 1-4 A dust-suppressing electric shovel is provided, comprising:

[0045] Main component 100: including a bucket 101, a baffle 102 at the bottom of the bucket 101, and a support arm 103 on one side of the bucket 101; Fixing component 200: including a mounting assembly 201, a sliding assembly 202 in the mounting assembly 201, and a connecting assembly 203 between the sliding assembly 202 and the baffle 102; wherein the mounting assembly 201 is located on both sides of the support arm 103, the top of the sliding assembly 202 is provided with a spraying component 300, the bottom of the bucket 101 is rotatably provided with the baffle 102, and one side of the bucket 101 is connected to the support arm 103, and the equipment drives the bucket 101 through the support arm 103. The bucket 101 scoops up the material. When the material is moved to the unloading area, the baffle 102 rotates to open the bottom of the bucket 101 for unloading. There are two sets of mounting components 201, which are respectively located on both sides of the support arm 103. The device is installed through the mounting components 201. When the baffle 102 rotates to unload the material, a lot of dust is generated in the unloading area. The connecting component 203 pushes the sliding component 202 to slide out of the mounting component 201, so that the sliding component 202 drives the spray component 300 to rise. After the spray component 300 rises, it sprays horizontally into the air in the unloading area to reduce the dispersion of dust in the air in the unloading area.

[0046] Specifically, the mounting component 201 includes a U-shaped frame 201a and a fixing cylinder 201b disposed on one side of the U-shaped frame 201a; wherein, the U-shaped frame 201a is sleeved on the support arm 103, the sliding component 202 is disposed in the fixing cylinder 201b, the U-shaped frame 201a is fixed to the support arm 103 by bolts or welding, the openings of the two sets of U-shaped frames 201a are disposed opposite each other on both sides of the support arm 103, and the fixing cylinder 201b is fixedly connected to the side of the two sets of U-shaped frames 201a that is far away from each other, and the fixing cylinder 201b is fixed to the support arm 103 by the U-shaped frame 201a.

[0047] Furthermore, the sliding assembly 202 includes a guide cylinder 202a, a guide plate 202b disposed at the top of the guide cylinder 202a, and a lifting rod 202c slidably disposed in the guide plate 202b; wherein, the guide cylinder 202a is fixedly disposed on the inner wall of the fixed cylinder 201b, the connecting assembly 203 is disposed at the bottom of the lifting rod 202c, the spraying component 300 is disposed at the top of the lifting rod 202c, the guide plate 202b is fixedly disposed at the top of the guide cylinder 202a, and a circular groove is opened in the middle of the guide plate 202b, through which the lifting rod 202c is slidably disposed in the guide plate 202b. c is located in the fixed cylinder 201b. When the lifting rod 202c slides to its maximum stroke, it will not disengage from the guide plate 202b. The guide plate 202b guides and limits the sliding of the lifting rod 202c, so that the lifting rod 202c slides stably longitudinally in the fixed cylinder 201b without tilting during the sliding process. When the lifting rod 202c is in the initial state, the spraying component 300 is also located in the fixed cylinder 201b. The lifting rod 202c slides out of the fixed cylinder 201b, causing the spraying component 300 to extend out of the top of the fixed cylinder 201b and spray water into the air to achieve the effect of dust reduction in the unloading area.

[0048] Furthermore, the connecting assembly 203 includes a short rod 203a, a spring 203b disposed on the outside of the short rod 203a, a guide plate 203c disposed at the bottom of the fixed cylinder 201b, and a cable 203d disposed between the baffle 102 and the short rod 203a; wherein, the short rod 203a is disposed at the bottom of the lifting rod 202c, and in this embodiment, the short rod 203a is fixedly disposed at the bottom of the lifting rod 202c, the diameter of the short rod 203a is smaller than the diameter of the lifting rod 202c, the cable 203d is fixedly connected to the bottom of the short rod 203a, the guide plate 203c is fixedly disposed at the bottom of the fixed cylinder 201b, and a guide tube is disposed at the middle position of the guide plate 203c. The diameter of the guide tube is smaller than that of the short rod 203a. The end of the cable 203d 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 203d. A spring 203b is sleeved on the outside of the short rod 203a. The top of the spring 203b abuts against the bottom of the lifting rod 202c, and its bottom abuts against the top of the guide plate 203c. When the baffle 102 rotates, the cable 203d is released, and the spring 203b abuts against the lifting rod 202c, pushing it to rise. The rising of the lifting rod 202c drives the spray component 300 to extend out of the fixed tube 201b. At this time, the spray component 300 is activated to spray dust in the unloading area.

[0049] Furthermore, the spraying component 300 includes a hinge seat 301, a rotating rod 302 disposed on the hinge seat 301, and a positioning member 303 disposed on the fixed cylinder 201b. The hinge seat 301 is disposed on the lifting rod 202c. Multiple sets of hinge seats 301 are fixedly disposed on the outer side of the top of the lifting rod 202c. The rotating rod 302 is rotatably connected to each set of hinge seats 301. Multiple sets of positioning members 303 are fixedly disposed on the inner wall of the fixed cylinder 201b. The number of positioning members 303 corresponds to the number of hinge seats 301. The rotating rod 302 is sleeved on the positioning member 303. The positioning member 303 limits and guides the rotating rod 302. When the lifting rod 202c rises, it drives the multiple sets of rotating rods 302 to move synchronously through the hinge seat 301. When the rotating rod 302 extends out of the fixed cylinder 201b, the rotating rod 302 is limited and unfolded by the positioning member 303, thereby increasing the spraying range.

[0050] Furthermore, the rotating rod 302 has a waist-shaped groove 302a and a nozzle 302b at its top; the positioning member 303 includes a fixing seat 303a on the inner wall of the fixing cylinder 201b and a fixing post 303b on the fixing seat 303a; wherein, the rotating rod 302 is sleeved with the fixing post 303b through the waist-shaped groove 302a. In this embodiment, multiple sets of fixing seats 303a are fixedly provided at the top of the inner wall of the fixing cylinder 201b, and each set of fixing seats 303a is fixedly provided with a fixing post 303b. The rotating rod 302 has a waist-shaped groove 302a corresponding to the fixing post 303b, and the fixing post 302a... A nozzle 302b is fixedly installed at the top of 3b. The nozzle 302b is connected to the water pump through a hose. When the lifting rod 202c rises, the rotating rod 302 slides outside the fixed column 303b through the waist-shaped groove 302a. The limiting position of the fixed column 303b causes the rotating rod 302 to rotate around the connection with the fixed seat 303a, causing multiple sets of nozzles 302b to move away from the lifting rod 202c and spread out, thereby increasing the spraying range. At the same time, the nozzles 302b are driven to rise by the lifting rod 202c, increasing the spraying height. The maximum rotation angle of the rotating rod 302 is 70 degrees, so that after the rotating rod 302 rotates, the nozzles 302b are still in a high position.

[0051] 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 bottom state of the closed bucket part 101. The cable 203d is pulled and is in a taut state. The lifting rod 202c is at the position corresponding to the guide cylinder 202a. The spring 203b is squeezed by the lifting rod 202c and is in a contracted state. Multiple sets of rotating rods 302 are driven by the lifting rod 202c and stored in the fixed cylinder 201b. At this time, the fixed column 303b is located at the top of the waist-shaped groove 302a.

[0052] 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 203d, and the spring 203b loses its compressive force, pushing the lifting rod 202c to rise. During the rise of the lifting rod 202c, the guide plate 202b guides and limits it. When the lifting rod 202c rises, it drives multiple sets of rotating rods 302 to move out of the fixed cylinder 201b. During the rise of the rotating rods 302, they slide outside the fixed column 303b. The fixed column 303b limits the rotating rods 302, causing them to rotate. This drives multiple sets of spray nozzles 302b to spread out. The water pump delivers spray water to the spray nozzles 302b, and the spray nozzles 302b spray to suppress dust in the surrounding environment.

[0053] When the electric shovel finishes unloading and the baffle 102 rotates to its reset position, the cable 203d is driven to pull the short rod 203a. The short rod 203a drives the lifting rod 202c to slide downwards. The spring 203b is compressed. At the same time, multiple sets of rotating rods 302 are driven to slide downwards by the lifting rod 202c. Due to the limitation of the fixed column 303b, the rotating rods 302 rotate and move closer to the lifting rod 202c, so that multiple sets of rotating rods 302 are stored in the fixed cylinder 201b.

[0054] When the electric shovel generates a large amount of smoke and dust in the unloading area, multiple sets of nozzles 302b automatically extend to spray water to suppress dust in the unloading area. The multiple sets of nozzles 302b 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.

[0055] Example 2

[0056] Reference Figures 1-7 This embodiment differs from the first embodiment in that it further includes an opening and closing component 400; it includes a mounting frame 401, a push switch 402 disposed on the mounting frame 401, a movable sleeve 403 disposed outside the push switch 402, and a limiting member 404 disposed between the movable sleeve 403 and the mounting frame 401; wherein, the mounting frame 401 is disposed between the lifting rod 202c and the short rod 203a. Unlike the first embodiment, in this embodiment, a mounting frame 401 is also provided between the lifting rod 202c and the short rod 203a. The push switch 402 is mounted on the mounting frame 401. The push switch 402 is electrically connected to the water pump, thereby controlling the opening and closing of the water pump. The movable sleeve 403 is slidably connected to the mounting frame 401 through the limiting member 404. The movable sleeve 403 is sleeved on the outside of the push switch 402, and the inner wall of the movable sleeve 403 is in contact with the outer side of the push switch 402, so that the movable sleeve 403 can slide laterally. The top of the movable sleeve 403 A second inclined plane L is provided, and a corresponding inclined plane S is provided at the bottom end of the guide cylinder 202a. The distance between the inner wall of the fixed cylinder 201b and the outer side of the lifting rod 202c is less than the distance between the end of the push switch 402 and the outer side of the mounting bracket 401. When the push switch 402 is located away from the guide cylinder 202a, it is in the relaxed state and the water pump is not started. When the lifting rod 202c rises, it drives the push switch 402 to rise synchronously through the mounting bracket 401. When rising, the inclined surface L of the movable sleeve 403 abuts against the inclined surface S of the guide cylinder 202a and slides in the first direction, which is the direction closer to the fixed frame. When the movable sleeve 403 moves to the inside of the guide cylinder 202a, the movable sleeve 403 slides and squeezes the press switch 402. The press switch 402 is squeezed and turns on the water pump, so that the water pump works to deliver water to the nozzle 302b. When the lifting rod 202c rises, the movable sleeve 403 always abuts against the inner wall of the guide cylinder 202a.

[0057] Specifically, the limiting component 404 includes a fixed plate 404a, a limiting post 404b disposed on the top of the movable sleeve 403, and a guide groove 404c opened on the fixed plate 404a; wherein, the fixed plate 404a is disposed on the outside of the mounting frame 401, the fixed plate 404a is sleeved with the limiting post 404b through the guide groove 404c, the outside of the mounting frame 401 is fixedly disposed on the fixed plate 404a, the mounting frame 401 has a guide groove 404c, the top of the movable sleeve 403 is fixedly disposed with the limiting post 404b, the limiting post 404b is slidably disposed in the guide groove 404c, so that the movable sleeve 403 is limited and guided to slide by the limiting post 404b.

[0058] The rest of the structure is the same as in Example 1.

[0059] Operating procedure: When the electric shovel is not unloading, the press switch 402 is located below the guide cylinder 202a. At this time, the press switch 402 is in the relaxed state and the water pump is not turned on.

[0060] When the material is unloaded and the lifting rod 202c rises, the lifting rod 202c drives the push switch 402 to rise through the mounting bracket 401. The inclined surface 2L of the moving sleeve 403 abuts against the inclined surface 1S of the guide cylinder 202a, causing the moving sleeve 403 to slide in the first direction. After the moving sleeve 403 slides, it abuts against the push switch 402. When the end of the moving sleeve 403 abuts against the inner wall of the positioning cylinder, the push switch 402 is pressed, and the water pump is turned on. At this time, the nozzle 302b has been driven out of the fixed cylinder 201b by the lifting rod 202c. The water pump delivers spray water to the nozzle 302b, so that the nozzle 302b sprays water on the environment to achieve the dust suppression effect. During the process of the lifting rod 202c rising, the moving sleeve 403 always abuts against the inner wall of the guide cylinder 202a.

[0061] When the baffle 102 rotates to reset and the electric shovel finishes unloading, the lifting rod 202c is driven to slide into the fixed cylinder 201b. At the same time, the push switch 402 is driven to descend synchronously. When the moving sleeve 403 moves away from the guide cylinder 202a, the push switch 402 automatically resets, the water pump is turned off, and the nozzle 302b stops spraying.

[0062] The water pump is controlled by the push switch 402 and automatically turns on only when the electric shovel is unloading material to supply water to the nozzle 302b 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.

[0063] Example 3

[0064] Reference Figures 1-10This embodiment differs from the previous embodiments in that it further includes a rotating component 500, which includes a guide post 501, a closing member 502 disposed at the top of the lifting rod 202c, an annular groove 201c opened on the fixed cylinder 201b, and a ring 503 disposed in the annular groove 201c; wherein, the guide post 501 is disposed on the inner wall of the guide cylinder 202a, and a spiral groove 202d is opened on the outer side of the lifting rod 202c, and the guide post 501 extends into the spiral groove 202d. Unlike the second embodiment, in this embodiment, the lifting rod 202c is rotatably connected to the mounting bracket 401, the guide post 501 is fixedly disposed at the upper inner side of the guide cylinder 202a, and the spiral groove 202d is opened on the outer side of the lifting rod 202c. When the lifting rod 202c has not risen... At this time, the guide post 501 is located at the top end of the spiral groove 202d. When the lifting rod 202c rises, the guide post 501 cooperates with the spiral groove 202d to guide the lifting rod 202c, causing the lifting rod 202c to rotate during the rising process. The rotation of the lifting rod 202c makes the water sprayed from the nozzle 302b more even. The top of the lifting rod 202c is fixedly provided with a sealing member 502. In this embodiment, the inner wall of the fixed cylinder 201b is also provided with an annular groove 201c. A circular ring 503 is rotatably connected in the annular groove 201c. Multiple sets of fixed seats 303a are fixedly provided inside the circular ring 503, so that the fixed seats 303a can rotate along with the lifting rod 202c during the rising and rotating process, so that the guide post 501 can still guide the rotating rod 302.

[0065] Specifically, the sealing component 502 includes a fixed rod 502a located at the top of the lifting rod 202c and a circular plate 502b located at the top of the fixed rod 502a. The fixed rod 502a is fixedly installed at the top of the lifting rod 202c, and the circular plate 502b is fixedly installed at the top of the fixed rod 502a. The diameter of the circular plate 502b is the same as the inner diameter of the fixed tube. When the rotating rod 302 is stored in the fixed tube, the circular plate 502b is driven to seal the top of the fixed tube, so that when the nozzle 302b is not in use, dust is reduced from entering the fixed tube, and the nozzle 302b is prevented from being blocked by dust.

[0066] The rest of the structure is the same as in Example 2.

[0067] Operation process: When the electric shovel is not unloading, the lifting rod 202c is located inside the guide cylinder 202a, the guide column 501 is located at the top of the spiral groove 202d, and the circular plate 502b closes the top of the fixed cylinder 201b.

[0068] When the baffle 102 rotates to unload material and the lifting rod 202c rises, the guide column 501 cooperates with the spiral groove 202d, so that the lifting rod 202c is guided to rotate by the guide column 501 during the rising process. The fixed seat 303a is rotatably connected to the fixed cylinder 201b through the ring 503. The rotation of the lifting rod 202c drives the ring 503 to rotate synchronously, so that the fixed column 303b can still guide the rotating rod 302 during the rotation and rising process. The lifting rod 202c drives multiple sets of nozzles 302b to rotate through the rotating rod 302. The nozzles 302b spray while rotating. At the same time, the rising of the lifting rod 202c drives the circular plate 502b to rise through the fixed rod 502a, so that the circular plate 502b will not block the nozzles 302b from extending. When the lifting rod 202c descends and resets, the nozzles 302b are stored in the fixed cylinder 201b, and the circular plate 502b closes the top of the fixed cylinder 201b again.

[0069] As the lifting rod 202c rotates during its ascent, the nozzle 302b rotates around the lifting rod 202c 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 302b is stored in the fixed cylinder 201b, the circular plate 502b seals the top of the fixed cylinder 201b, preventing dust from entering the fixed cylinder 201b and clogging the nozzle 302b.

[0070] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative.
