Description

Technical Field

[0001] This utility model belongs to the field of dust suppression technology for bucket wheel excavators, specifically relating to a dust suppression device for bucket wheel excavators in coal yards. Background Technology

[0002] Bucket wheel excavators are high-efficiency loading and unloading machines used in large bulk cargo yards. They can both stack and retrieve materials, and have advantages such as high efficiency, continuity, strong adaptability, and high degree of automation. They are widely used in coal yards. During operation, bucket wheel excavators mainly use the bucket wheel for loading and unloading. Therefore, dust is relatively serious at the bucket wheel location. When the bucket wheel moves large or fast, or when there is wind, the dust will be even worse. If dust suppression measures are not taken, it will have an adverse impact on the surrounding environment and the health of workers. Utility Model Content

[0003] This utility model provides a dust suppression device for a coal yard bucket wheel excavator. It features a dust suppression device where gravity components one and two apply different gravities to the dust cover as the height of the dust suppression component changes. This allows the dust cover to rotate and make way for and shield the bucket. When the dust suppression component is located in the upper part of the bucket wheel body, the dust cover shields the space between two adjacent buckets, thereby achieving the purpose of dust suppression.

[0004] This utility model provides the following technical solution: It includes a bucket wheel body, with several dust suppression components on the outer side of the bucket wheel body. Each dust suppression component includes a dust cover, a connecting ring, and a connecting cylinder. The dust covers are respectively located on the outer sides of several buckets of the bucket wheel body. The connecting ring and the connecting cylinder are rotatably connected to the wheel body of the bucket wheel body. A first fixed column and a second fixed column are fixedly connected to the outer side of the connecting cylinder. The second fixed column is located on one side of the dust cover. The included angle between the first fixed column and the second fixed column is an obtuse angle. Gravity component one and gravity component two are respectively provided on the first fixed column and the second fixed column. Gravity component one includes a movable column one and a gravity ball one. Gravity component two includes a movable column two and a gravity ball two. The movable column one is slidably connected to the outer side of the first fixed column, and the movable column two is slidably connected to the outer side of the second fixed column. The total weight of the gravity ball two and the dust cover is the same as that of the gravity ball one.

[0005] The dust cover is matched with the size of the bucket on the bucket wheel body, and the inner side of the dust cover is in contact with the outer side of the bucket on the bucket wheel body.

[0006] The bucket wheel body has several connecting seats on both sides, and the connecting ring and the connecting cylinder are rotatably connected to the connecting seats.

[0007] Among them, the fixed column one and the fixed column two have the same size, the movable column one and the movable column two have the same size, and the gravity ball two has a smaller size than the gravity ball one.

[0008] Both the first movable column and the second movable column have slots on their inner sides, and springs are provided on the inner sides of the slots. The first fixed column is connected to the first movable column by a spring, and the second fixed column is connected to the second movable column by a spring.

[0009] The connecting cylinder has a guide plate 1 and a guide plate 2 on its outer side, a connecting block 1 on the movable column 1 and a connecting block 2 on the movable column 2, and a guide groove on both the guide plate 1 and the guide plate 2. The connecting block 1 and the connecting block 2 are slidably connected to the guide groove.

[0010] The beneficial effects of this utility model are as follows: By applying different gravity forces to the dust cover when the height of the dust-reducing component changes through gravity component one and gravity component two, the dust cover can rotate to make way for and shield the bucket. When the dust-reducing component is located in the upper part of the bucket wheel body, the dust cover shields the space between two adjacent buckets, which can prevent the material inside the bucket from being exposed to the wind and generating dust. It can also reduce the upward dust generated when the material is unloaded, thereby achieving the purpose of dust reduction and reducing the adverse effects of dust on the surrounding environment and the health of workers.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please see Figures 1-4 This utility model provides the following technical solution: It includes a bucket wheel body 1, with several dust suppression components 2 arranged on the outer side of the bucket wheel body 1. Each dust suppression component 2 includes a dust cover 21, a connecting ring 211, and a connecting cylinder 212. The several dust covers 21 are respectively located on the outer side of several buckets of the bucket wheel body 1. The connecting ring 211 and the connecting cylinder 212 are rotatably connected to the wheel body of the bucket wheel body 1. A first fixing post 22 and a second fixing post 23 are fixedly connected to the outer side of the connecting cylinder 212. The second fixing post 23 is located on one side of the dust cover 21. The included angle between the first fixed column 22 and the second fixed column 23 is an obtuse angle. The first fixed column 22 and the second fixed column 23 are respectively equipped with a gravity component 3 and a gravity component 4. The gravity component 3 includes a movable column 31 and a gravity ball 32. The gravity component 4 includes a movable column 41 and a gravity ball 42. The movable column 31 is slidably connected to the outside of the first fixed column 22. The movable column 41 is slidably connected to the outside of the second fixed column 23. The total weight of the gravity ball 42 and the dust cover 21 is the same as that of the gravity ball 32.

[0018] This implementation plan includes a bucket wheel body 1, which is the material-collecting working mechanism on the bucket wheel machine. The rotation of the bucket wheel body 1 allows the buckets on it to scoop up materials. Several dust-reducing components 2 are provided on the outer side of the bucket wheel body 1 to prevent dust from entering the buckets. Each dust-reducing component 2 includes a dust cover 21, a connecting ring 211, and a connecting cylinder 212. The connecting ring 211 and the connecting cylinder 212 are fixedly connected to the dust cover 21, and their positions are opposite. Several dust covers 21 are located on the outer side of several buckets on the bucket wheel body 1. By rotating the dust covers 21, they cover the outside of the buckets, thus reducing the amount of material blown up by the wind. In cases where dust is generated or spreads outward during material feeding, the connecting ring 211 and connecting cylinder 212 are rotatably connected to the bucket wheel body 1. The rotation between the connecting ring 211 and connecting cylinder 212 and the bucket wheel body 1 allows the angle of the dust cover 21 to change. This rotation of the dust cover 21 can cover or reposition the bucket of the bucket wheel body 1. Two fixing posts, a first fixing post 22 and a second fixing post 23, are fixedly connected to the outer side of the connecting cylinder 212. The second fixing post 23 is located on one side of the dust cover 21, with a gap between it and the dust cover 21. The included angle between the first fixing post 22 and the second fixing post 23 is an obtuse angle. As the bucket wheel body 1 rotates, the vertical position of the first fixing post 22 and the second fixing post 23 relative to the connecting cylinder 212 changes. Gravity component 3 and gravity component 4 are respectively installed on fixed column 1 22 and fixed column 2 23. These components can drive the dust cover 21 to rotate. Gravity component 1 3 includes a movable column 31 and a gravity ball 32, which is fixedly connected to the movable column 31. Gravity component 2 4 includes a movable column 41 and a gravity ball 42, which is fixedly connected to the movable column 41, but the two are not in contact. The movable column 31 is slidably connected to the outside of fixed column 22. When the movable column 31 is tilted downwards, gravity component 3 will slide downwards. As the distance between gravity ball 32 and connecting cylinder 212 increases, the downward gravity force on gravity component 3 increases. The downward force of gravity component 24 is greater than that of gravity component 3, causing the movable column 241 to slide on the outside of the fixed column 23. When the movable column 241 is tilted downwards, gravity component 24 will slide downwards, increasing the distance between gravity ball 242 and connecting cylinder 212. The downward force of gravity component 24 is greater than that of gravity component 3, thus causing the dust cover 21 to rotate. The total weight of gravity ball 242 and dust cover 21 is the same as that of gravity ball 32. When the dust cover 21 is at the bottom of the bucket wheel body 1, gravity component 24 will be tilted downwards, increasing the distance between gravity ball 242 and connecting cylinder 212. Meanwhile, gravity component 3 will be tilted upwards, increasing the distance between gravity ball 242 and connecting cylinder 212.As the distance between gravity ball 32 and connecting cylinder 212 decreases, the downward force of gravity component 4 is greater than that of gravity component 3. The dust cover 21 then rotates downwards with gravity component 4, placing it at the bottom of the bucket and preventing interference with material handling. When the dust cover 21 is located on the upper part of the bucket wheel body 1, gravity component 3 is tilted downwards and slides downwards. This increases the distance between gravity ball 32 and connecting cylinder 212, while gravity component 4 tilts upwards. As gravity component 2 4 slides downwards, the distance between gravity ball 2 42 and connecting cylinder 212 decreases. Therefore, the downward force of gravity component 3 is greater than that of gravity component 2 4, causing the dust cover 21 to rotate and shield the space between adjacent buckets. This prevents the material inside the buckets from being exposed to the wind and generating dust. Simultaneously, it reduces upward dust generated during material unloading, thus achieving dust suppression and minimizing the adverse effects of dust on the surrounding environment and the health of workers.

[0019] The dust cover 21 is matched with the size of the bucket on the bucket wheel body 1, and the inner side of the dust cover 21 contacts the outer side of the bucket on the bucket wheel body 1; when the dust cover 21 rotates on the outer side of the bucket, the inner side of the dust cover 21 will slide against the outer side of the bucket.

[0020] The bucket wheel body 1 has several connecting seats 11 on both sides of the wheel body. The connecting ring 211 and the connecting cylinder 212 are rotatably connected to the connecting seats 11. The positions of the several connecting seats 11 correspond to the positions of the several buckets. Through the connection between the connecting ring 211 and the connecting cylinder 212 and the connecting seats 11, the dust cover 21 can rotate around the connecting seat 11.

[0021] Fixed column 1 22 and fixed column 2 23 have the same dimensions, movable column 1 31 and movable column 2 41 have the same dimensions, and gravity ball 2 42 has a smaller dimensions than gravity ball 1 32; fixed column 1 22 and fixed column 2 23 are symmetrical to each other, movable column 1 31 and movable column 2 41 are symmetrical to each other, and the total weight of gravity ball 2 42 and dust cover 21 is the same as the weight of gravity ball 1 32.

[0022] Both movable column 1 31 and movable column 2 41 have slots 311 on their inner sides, and springs 312 are provided on the inner side of the slots 311. Fixed column 1 22 is connected to movable column 1 31 by springs 312, and fixed column 2 23 is connected to movable column 2 41 by springs 312. Through the connection of springs 312, gravity component 1 3 or gravity component 2 4 can slide down quickly when tilted upward.

[0023] The outer side of the connecting cylinder 212 is provided with a guide plate 24 and a guide plate 25. The movable column 31 is provided with a connecting block 313 and the movable column 41 is provided with a connecting block 411. The guide plate 24 and the guide plate 25 are both provided with guide grooves 241. The connecting block 313 and the connecting block 411 are slidably connected to the guide grooves 241. Through the connection between the connecting block 313 and the connecting block 411 and the guide grooves 241, the slippage of the gravity component 3 and the gravity component 4 can be avoided.

[0024] The working principle and usage process of this utility model are as follows: When the dust cover 21 is located at the bottom of the bucket wheel body 1, the gravity component 2 4 will be tilted downwards. As the gravity component 2 4 slides downwards, the distance between the gravity ball 2 42 and the connecting cylinder 212 increases. Meanwhile, the gravity component 1 3 will be tilted upwards. As the gravity component 1 3 slides downwards, the distance between the gravity ball 1 32 and the connecting cylinder 212 decreases. Therefore, the downward force of gravity component 2 4 is greater than that of gravity component 1 3, and the dust cover 21 will rotate downwards with gravity component 2 4. Gravity component 2 4 will then be positioned... Located at the bottom of the bucket, it will not interfere with the bucket's material handling. When the dust cover 21 is located in the upper part of the bucket wheel body 1, the gravity component 1 3 will be tilted downwards. The gravity component 1 3 slides downwards, and the distance between the gravity ball 1 32 and the connecting cylinder 212 increases. Meanwhile, the gravity component 2 4 tilts upwards, and the gravity component 2 4 slides downwards, and the distance between the gravity ball 2 42 and the connecting cylinder 212 decreases. Therefore, the downward gravity of the gravity component 1 3 is greater than that of the gravity component 2 4, which will cause the dust cover 21 to rotate and block the space between the two adjacent buckets.
