Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] A coal preparation plant spray dust reduction device comprises a cart 1, a spray mechanism 3 is arranged on the top of the cart 1, a multi-directional mechanism 2 is arranged on the top of the bucket of the spray mechanism 3 for dust reduction at different angles, and the multi-directional mechanism 2 comprises:

[0028] The up-down component 21 is arranged at the top of the spray mechanism 3, and includes a linkage ring 218. The linkage ring 218 is circular in shape, and a slide groove 219 is provided inside the linkage ring 218. The slide groove 219 is circular in shape. Four fixed rods 217 are fixedly installed at the bottom of the linkage ring 218, and a lifting block 215 is fixedly installed at one end of the fixed rod 217. The outer ring of the lifting block 215 has a limiting groove 216. The up-down component 21 also includes a mounting shell 211 fixedly installed on the top of the water bucket of the spray mechanism 3. A first motor 212 is fixedly installed on the top of the mounting shell 211. The first motor 212 is a three-phase asynchronous motor, which is electrically connected to an external power supply and is opened and closed by a person operating the control panel. The first motor 21 2 is fixedly installed with a Y-shaped connecting rod 213 at one end of the output shaft, and the shape of the Y-shaped connecting rod 213 is Y-shaped. Sliding columns 214 are fixedly installed on the inner sides of both ends of the Y-shaped connecting rod 213, and the sliding columns 214 are adapted to slide inside the limiting groove 216. The operation of the first motor 212 drives the Y-shaped connecting rod 213 to move in a circular motion with the axis of the output shaft of the first motor 212, and the Y-shaped connecting rod 213 drives the lifting block 215 to slide up and down inside the limiting groove 216 through two sliding columns 214. When the lifting block 215 moves up and down, the linkage ring 218 drives the linkage rod 224 to rotate with the connecting sleeve rod 223 as the axis, thereby driving the disassembly assembly 23 to move in an up and down circular motion, thereby realizing dust reduction work in the up and down directions, and improving work efficiency;

[0029] The left-right component 22 is disposed inside the up-down component 21 and is used to assist in dust reduction at different angles;

[0030] The disassembly assembly 23 is arranged above the left-right assembly 22 and is used to facilitate the disassembly of the spray gun.

[0031] In this embodiment, the left-right assembly 22 includes a second motor 221 fixedly mounted on the top of the inner cavity of the mounting shell 211. The second motor 221 is a three-phase asynchronous motor, which is electrically connected to an external power supply and is opened and closed by a person operating the control panel. The output end of the second motor 221 is rotatably mounted with a rotating shaft 222, and the rotating shaft 222 rotates through the top plate of the mounting shell 211 and is fixedly connected to the inside of the lifting block 215 with a connecting rod 223, and the inside of the connecting rod 223 is rotatably mounted with a linkage rod 224, and the left end of the linkage rod 224 is fixedly mounted. There is an L-rod 225, and a connecting column 226 is fixedly installed on the top of the L-rod 225. The lifting block 215 is mounted on the outer ring of the rotating shaft 222 and slides up and down on the outer ring of the rotating shaft 222. The second motor 221 is running, and the connecting sleeve rod 223 is driven to rotate through the rotating shaft 222. At this time, the ball at one end of the linkage rod 224 slides inside the slide groove 219, so that the connecting sleeve rod 223 rotates to drive the L-rod 225 and the connecting column 226 to rotate left and right, and simultaneously drives the disassembly and assembly component 23 to move left and right, thereby realizing dust reduction work in the left and right directions and improving work efficiency.

[0032] In this embodiment, the disassembly and assembly component 23 includes a mounting ring 231 fixedly mounted on the top of the connecting column 226, a threaded knob 232 is rotatably inserted into the top thread of the mounting ring 231, and a clamping plate 233 is fixedly mounted on the bottom end of the threaded knob 232. The user rotates the threaded knob 232 to make the clamping plate 233 rise and fall, thereby realizing the replacement of the spray gun. Therefore, during the operation of the equipment, the spray gun may need to be replaced or repaired for various reasons. The traditional disassembly and assembly method is often time-consuming and labor-intensive, while the quick disassembly and assembly structure can greatly shorten this process, allowing maintenance personnel to complete their work more quickly and reduce the time of production interruption, thereby ensuring the continuous and stable operation of the coal preparation plant.

[0033] In this embodiment, one end of the linkage rod 224 with a ball is slidably installed inside the slide groove 219, and the shape of the linkage rod 224 is Z-shaped, so that the up and down components 21 and the left and right components 22 can run synchronously, realizing the oblique spraying and dust reduction work of the spray gun.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] During operation, the user first connects the device to an external power source, then inserts the spray gun into the interior of the mounting ring 231, and turns the threaded knob 232 to clamp the spray gun through the clamping plate 233. Then, the first motor 212 drives the Y-shaped connecting rod 213 to move in a circular motion with the axis of the output shaft of the first motor 212, and the Y-shaped connecting rod 213 drives the lifting block 215 to slide up and down inside the limiting groove 216 through two sliding columns 214. When the lifting block 215 moves up and down, the linkage ring 218 drives the linkage rod 224 to rotate with the connecting sleeve rod 223 as the axis, thereby driving the disassembly and assembly component 23 to move in a circular motion up and down, and the second motor 221 runs, driving the connecting sleeve rod 223 to rotate through the rotating shaft 222. At this time, the ball at one end of the linkage rod 224 slides inside the slide groove 219, so that the connecting sleeve rod 223 rotates to drive the L rod 225 and the connecting column 226 to rotate left and right, and simultaneously drives the disassembly and assembly component 23 to move left and right, so as to perform dust reduction work in different directions.
