Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] See Figures 1-3 This utility model provides a dust suppression device, including a base 1 and an adjustment component 2. The base 1 is set on the ground (or other supporting surface). Users can add casters at the four corners of the bottom surface of the base 1 to facilitate the movement of the device.

[0022] See Figures 1-3 The adjusting assembly 2 includes a gear disk 21 and a reciprocating lead screw 22. The gear disk 21 is rotatably mounted in the center of the top surface of the base 1. The reciprocating lead screw 22 is rotatably mounted on both sides of the gear disk 21. Both ends of the reciprocating lead screw 22 are rotatably connected to the side wall of the base 1. The surface of the reciprocating lead screw 22 is provided with reciprocating threads. The reciprocating lead screw 22 is threadedly connected with a rack 23. The rack 23 meshes with the gear disk 21 and is slidably connected to the base 1. When the reciprocating lead screw 22 rotates in one direction, it can drive the rack 23 to reciprocate along the reciprocating lead screw 22. When the two reciprocating lead screws 22 rotate in the same direction, the two racks 23 move in opposite directions, avoiding the situation where the gear disk 21 cannot rotate. One end of the reciprocating screw 22 is rotatably fitted with a forward rotation sleeve 221. One side wall of the forward rotation sleeve 221 is provided with a forward ratchet. The forward ratchet, the forward rotation sleeve 221 and the reciprocating screw 22 are concentric. The reciprocating screw 22 is rotatably provided with a unidirectional rotatable pawl. When the forward ratchet and the forward pawl are engaged, the forward rotation sleeve 221 can drive the reciprocating screw 22 to rotate synchronously in the forward direction.

[0023] See Figures 1-3Several dust-suppressing pipes 24 are provided above the gear disk 21. The base 1 has an inner cavity. The dust-suppressing pipes 24 are all connected to the inner cavity of the base 1 through pipes. The dust-suppressing pipes 24 are used for dust suppression (in the prior art, dust suppression is generally carried out by spraying or air exchange. Spray dust suppression refers to the method of dispersing water into droplets and spraying them toward the dust source to suppress and capture dust. In this case, the dust-suppressing pipe 24 is a spray pipe. The other mechanisms that cooperate with the spray pipe are placed inside the base 1. Air exchange dust suppression involves sucking dust into the base 1 through air exchange and filling the base 1 with a certain amount of water to mix the dust with the water. In this case, the dust-suppressing pipe 24 is an air exchange pipe with rotatable fan blades inside. The above dust suppression methods are all prior art. Users can choose the appropriate dust suppression method according to the actual situation, so they will not be described in detail). The bottom of the dust-suppressing pipes 24 are all rotatably connected to the connecting seat 241. The connecting seat 241 is fixedly connected to the gear disk 21. A lifting ring 25 is provided above the gear disk 21. Several rotating slide pieces 251 are slidably provided on the lifting ring 25. The top surface of the lifting ring 25 is provided with an annular groove that cooperates with the rotating slide pieces 251, so that the rotating slide pieces 251 can slide relative to the lifting ring 25. Sliding sleeves 242 are slidably fitted on the dust collection pipes 24. Fixed connecting rods 252 are provided between the sliding sleeves 242 and the rotating slide pieces 251. One end of the fixed connecting rod 252 is fixedly connected to the rotating slide piece 251, and the other end of the fixed connecting rod 252 is rotatably connected to the sliding sleeve 242. When the lifting ring 25 rises and falls, under the action of the fixed connecting rods 252, it can drive several dust collection pipes 24 to rotate with the connection point between them and the connecting seat 241 as the center.

[0024] See Figures 1-3 Both sides of the lifting ring 25 are provided with extension plates 26, and a rotating shaft 27 is rotatably provided below the extension plates 26. Both ends of the rotating shaft 27 are rotatably connected to the side wall of the base 1. Two movable seats 28 are provided on the rotating shaft 27. The surface of the rotating shaft 27 is provided with two circulation grooves in opposite directions (the circulation groove is an arc-shaped groove that surrounds the rotating shaft 27 and is connected end to end). The movable seats 28 are matched with the circulation grooves one by one (that is, the movable seats 28 are provided with through holes for the rotating shaft 27 to pass through, and the inner side wall of the through holes is provided with guide posts that cooperate with the circulation grooves). A rotating connecting rod 281 is rotatably provided between the movable seats 28 and the extension plates 26 (that is, one end of the rotating connecting rod 281 is rotatably connected to the extension plate 26, and the other end of the rotating connecting rod 281 is rotatably connected to the movable seat 28). One end of each rotating shaft 27 is rotatably equipped with a reversing sleeve 271. Each reversing sleeve 271 has a reversing ratchet on one side wall. The reversing ratchet, reversing sleeve 271, and rotating shaft 27 are concentric. A unidirectional reversing pawl is rotatably mounted on the rotating shaft 27. When the reversing ratchet engages with the reversing pawl, the reversing sleeve 271 can drive the rotating shaft 27 to rotate synchronously in reverse. A driving member 29 is provided on one side wall of the base 1. A belt is connected between the output shaft of the driving member 29, the forward rotating sleeve 221, and the reversing sleeve 271.

[0025] See Figures 1-3Preferably, the belt drive in this application can be replaced with a chain drive to ensure good transmission efficiency. The addition of transmission gears and the matching of chains and gears are conventional technical operations for those skilled in the art, and therefore will not be described in detail.

[0026] See Figures 1-3 Preferably, several limiting rods passing through the movable seat 28 are provided next to the rotating shaft 27, and both ends of the limiting rods are connected to the side wall of the base 1, which can prevent the movable seat 28 from rotating.

[0027] See Figures 1-3 Preferably, the drive unit 29 is a rotary motor that can provide sufficient power.

[0028] In the implementation of this utility model: the user places the base 1 in a suitable location and starts the drive unit 29. The drive unit 29 rotates forward. At this time, the forward ratchet engages with the forward pawl, while the reverse ratchet does not engage with the reverse pawl. The forward rotating bushing 221 drives the reciprocating screw 22 to rotate forward, while the reverse rotating bushing 271 cannot drive the rotating shaft 27 to rotate in reverse. The rotation of the reciprocating screw 22 drives the rack 23 to move, thereby causing the gear disk 21 to drive the several dust-collecting pipes 24 mounted on it to rotate. The horizontal angle of the dust-collecting pipes 24 is adjusted, and then the drive unit... 29. Reverse rotation: at this time, the forward ratchet does not engage with the forward pawl, and the reverse ratchet engages with the reverse pawl. The forward rotation sleeve 221 cannot drive the reciprocating screw 22 to rotate forward. The reverse rotation sleeve 271 drives the rotating shaft 27 to rotate in reverse. The two moving seats 28 on the same rotating shaft 27 move closer to each other (or further apart), thereby driving the lifting ring 25 to descend (or ascend). Under the action of the fixed connecting rod 252, it drives several dust-collecting pipes 24 to rotate with their connection point with the connecting seat 241 as the center, adjusting the vertical angle of the dust-collecting pipes 24.

[0029] This utility model provides a dust suppression device, which has the following beneficial effects:

[0030] 1. By setting the adjustment component, the horizontal and vertical rotation angles of the dust collection pipe can be adjusted, expanding the dust collection range and meeting the user's needs.

[0031] 2. The multi-directional adjustment of the dust collection pipe in this application can be completed by a single drive component, which reduces the cost of use and meets the needs of enterprises to reduce costs and increase efficiency.

[0032] In summary, the beneficial effects of this utility model are: it can adjust the dust collection pipe in multiple directions, expanding the dust collection range, and it can also reduce the cost of use and meet the needs of use.

[0033] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
