Description

Technical Field

[0001] This invention relates to the field of dust suppression technology for mining cars, and in particular to a dust suppression device for mining car buckets. Background Technology

[0002] Dust is easily generated when open-pit mine cars are loading goods. The most common method is to set up dust suppression equipment next to the loading of the mine cars to suppress dust. However, the loading position changes constantly with the progress of the operation, while the dust suppression equipment is fixed and cannot be moved. This results in the need to move the dust suppression equipment constantly, which is cumbersome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a dust suppression device for the mining car bucket that can be installed on a mining car.

[0004] To address the aforementioned problems, this invention provides a dust suppression device for a mine car bucket. The dust suppression device for the mine car bucket includes a drive unit, a mounting frame, a bucket sprayer, and a connector. The drive unit includes a drive motor, an output gear, a transmission gear, a transmission shaft, a drive seat, a commutator, a drive rod, and a drive housing. The drive motor is installed inside the drive housing. The output gear is installed at the output end of the drive motor. There are two transmission gears and two transmission shafts, both rotatably mounted inside the drive housing. The two transmission gears are respectively mounted on two transmission shafts. The output gear meshes with one of the transmission gears. The drive rod is located inside the drive seat. The commutator is rotatably mounted on the drive housing. The commutator guides the drive rod from one drive seat to the other drive seat. The drive rod is connected to the connector, which is connected to the bucket sprayer. The bucket sprayer is mounted on the mounting frame and can swing left and right and up and down on the mounting frame.

[0005] Furthermore, the drive base includes two drive discs, which are mounted at intervals on the drive shaft. Each drive disc has a positioning notch, and the drive rod is located within the positioning notch.

[0006] Furthermore, the drive rod is provided with two positioning parts, which abut against the two drive discs respectively.

[0007] Furthermore, the commutator includes a commutator rod, a commutator frame, and a spring. The commutator rod is rotatably mounted on the commutator frame, which is installed inside the drive housing. One end of the spring is connected to the bogie, and the other end of the spring is connected to the commutator rod.

[0008] Furthermore, the commutator includes a commutator base and a commutator connecting rod, the commutator connecting rod is connected to the commutator base, the commutator rod is rotatably mounted on the commutator connecting rod, the commutator rod is T-shaped, and the commutator base is arranged laterally.

[0009] Furthermore, the truck bed sprayer includes a truck bed nozzle, a connecting pipe, and a connecting block. The truck bed nozzle is mounted on the connecting pipe, the connecting pipe is mounted on the connecting block, the connecting block is rotatably mounted on a mounting bracket, and the connector is connected to the connecting block.

[0010] Furthermore, the connector includes a telescopic tube and a universal joint, the universal joint being connected to the telescopic tube, the universal joint also being connected to the drive rod of the drive device, and the telescopic tube also being connected to the connecting block of the truck bed sprayer.

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, a preferred embodiment of the dust suppression device 3 for a mining car bucket of the present invention includes a drive unit 31, a mounting frame 32, a car bucket sprayer 33, and a connector 34. The drive unit 31 is mounted on the car bucket 11 and connected to the connector 34. The drive unit 31 drives the connector 34 to move. The connector 34 is connected to the car bucket sprayer 33, which is mounted on the mounting frame 32. The car bucket sprayer 33 can swing left and right and up and down on the mounting frame 32. The drive unit 31 drives the connector 34 to move in an ∞-shape in the vertical plane. The connector 34 drives the car bucket sprayer 33 to swing on the mounting frame 32, enabling the car bucket sprayer 33 to spray forward and backward and swing left and right, achieving basic coverage of the entire car bucket 11 with a single power source, while occupying little space.

[0025] The driving device 31 includes a drive motor 311, an output gear 312, a transmission gear 313, a transmission shaft 314, a drive seat 315, a commutator 316, a drive rod 317, and a drive housing 318. The drive motor 311 is installed inside the drive housing 318, and the output gear 312 is installed at the output end of the drive motor 311, driving the output gear 312 to rotate. There are two transmission gears 313 and two transmission shafts 314. The two transmission gears 313 are respectively installed on two transmission shafts 314, and the output gear 312 meshes with one of the transmission gears 313, driving the transmission gear 313 to rotate. The transmission shafts 314 are rotatably installed inside the drive housing 318, and the two transmission shafts 314 are arranged side-by-side, driving both transmission shafts 314 to rotate. There are two drive seats 315, each fixed to one of the two transmission shafts 314, and the transmission shafts 314 drive the drive seats 315 to rotate synchronously. The drive rod 317 is disposed within one of the drive seats 315, and the rotation of the drive seat drives the drive rod 317 to move. The commutator 316 is rotatably mounted on the drive housing 318, and the commutator 316 is used to guide the drive rod 317, so that the drive rod 317 moves from one drive seat 315 into another drive seat 315. The drive motor 311 drives the gear to rotate, the output gear 312 rotates and drives the two transmission gears 313 to rotate synchronously, the transmission gears 313 rotate and drive the two transmission shafts 314 to rotate synchronously, the transmission shafts 314 rotate and drive the two drive seats 315 to rotate synchronously, the drive seats 315 rotate and drive the drive rod 317 to move. When the drive rod 317 moves to the position of the commutator 316, the drive rod 317, guided by the commutator 316, will move from the current drive seat 315 into another drive seat 315. After moving a certain distance, the drive rod 317 will also change the guiding direction of the commutator 316, so that when the drive rod 317 contacts the commutator 316 again, the commutator 316 can guide the drive rod 317 back to the original drive seat 315, thereby realizing the reciprocating motion of the drive rod 317 in an ∞ shape.

[0026] like Figure 5 As shown, the drive base 315 includes two drive discs 3151, which are spaced apart and mounted on the transmission shaft 314. Each drive disc 3151 has a positioning notch 3152, and the drive rod 317 is located within the positioning notch 3152. The positioning notch 3152 is U-shaped, ensuring that the drive rod 317 can fully enter the positioning notch 3152, while also facilitating the sliding of the drive rod 317 out of the positioning notch 3152.

[0027] like Figure 6As shown, the drive rod 317 is provided with two positioning parts 3171. Each positioning part 3171 abuts against one of the two drive discs 3151. Specifically, the positioning part 3171 located at the rear abuts against the rear side of its corresponding drive disc 3151, and the positioning part 3171 located at the front abuts against the front side of its corresponding drive disc 3151. The two positioning parts 3171 and the two drive discs 3151 together restrict movement, ensuring that the drive rod 317 cannot move forward or backward. The diameter of the positioning part 3171 is larger than the positioning notch 3152, thus ensuring that the positioning part 3171 effectively restricts the drive rod 317.

[0028] like Figure 7As shown, the commutator 316 includes a commutator rod 3161, a commutator frame 3162, and a spring 3163. The commutator rod 3161 is rotatably mounted on the commutator frame 3162. The commutator rod 3161 is normally tilted to one side. The commutator rod 3161 guides the movement direction of the drive rod 317. After the commutator rod 3161 is commutated by the drive rod 317, the drive rod 317 drives the commutator rod 3161 to rotate, causing the commutator rod 3161 to tilt towards the side where the drive rod 317 is located. This allows the commutator rod 3161 to change the position of the drive rod 317 the next time it contacts the drive rod 317. When the commutator rod 3161 is tilted to one side, the commutator frame 3162 supports the commutator rod 3161. The commutator 3162 is installed inside the drive housing 318. One end of the spring 3163 is connected to the bogie, and the other end is connected to the commutator rod 3161. The connection point of the spring 3163 to the bogie and the connection point of the commutator rod 3161 to the commutator 3162 are on the same vertical line. This ensures that when the commutator rod 3161 tilts, the spring 3163 keeps the commutator in the tilting direction. As shown in the figure, when the drive rod 317 rotates counterclockwise around the drive shaft 314 under the drive of the right commutator seat, the commutator rod 3161 initially tilts to the right, and the spring 3163 also tilts to the right. After the drive rod 317 rotates to the position notch 3152 of the left drive seat 315 under the guidance of the commutator rod 3161, the drive rod 317 rotates clockwise under the drive of the left drive seat 315. During the rotation, the drive rod 3162... Drive rod 317 drives reversing lever 3161 to tilt to the left. Simultaneously, spring 3163 is also tilted to the left by reversing lever 3161. After being driven to reversing lever 3161 by drive seat 315, drive rod 317 then moves from the left drive seat 315 to the right drive seat 315. The right drive seat 315 drives drive rod 317 to rotate counterclockwise, causing reversing lever 3161 to tilt to the right and return to its initial position. This cycle repeats, enabling drive rod 317 to move in an ∞-shaped pattern. The spring 3163 keeps reversing lever 3161 tilted to the right, preventing it from shifting due to vehicle bumps.

[0029] The commutator 3161 is T-shaped, which ensures that the commutator 3161 can be supported by the commutator frame 3162 when it is tilted.

[0030] The commutator 3162 includes a commutator base 31621 and a commutator connecting rod 31622. The commutator connecting rod 31622 is connected to the commutator base 31621. The commutator rod 3161 is rotatably mounted on the commutator connecting rod 31622. The commutator connecting rod 31622 is vertically arranged, and the commutator base 31621 is horizontally arranged, thus ensuring that there is sufficient length to support the commutator rod 3161.

[0031] The drive housing 318 has a movable opening 3181, and one end of the drive seat 315 is located at the opening, thus facilitating the movement of the drive rod 317 between the two drive seats 315. The drive housing 318 has a mounting step, and the drive motor 311 is mounted on the mounting step.

[0032] like Figure 8 As shown, the truck bed sprayer 33 includes a truck bed nozzle 11, a connecting pipe 332, and a connecting seat 21. The truck bed nozzle 11 is mounted on the connecting pipe 332, which has an interface. The connecting pipe 332 is mounted on the connecting seat 21, which is rotatably mounted on a mounting frame 32. The connector 34 is connected to the connecting seat 21. Specifically, the connecting seat 21 has shafts 334 on both sides, which are rotatably mounted on the mounting frame 32. The shafts 334 are connected by screws for easy assembly and disassembly. Of course, in other embodiments, welding or integral molding can also be used for connection.

[0033] The mounting bracket 32 ​​includes a mounting base 321 and a mounting bracket 322. The mounting bracket 322 is rotatably mounted on the mounting base 321, and the mounting base 321 is mounted on the truck bed 11 of the vehicle body. The mounting bracket 322 is U-shaped, and the shaft 334 of the connecting seat 21 is rotatably mounted on the mounting bracket 322.

[0034] The connector 34 includes a telescopic tube 341 and a universal joint 342. The universal joint 342 is connected to the telescopic tube 341 and is also connected to the drive rod 317 of the drive device 31. The telescopic tube 341 is also connected to the connecting seat 21 of the truck bed sprayer 33. The drive rod 317 drives the universal joint 342 to move, and the movement of the universal joint 342 causes the telescopic tube 341 to deflect, thereby extending the telescopic tube 341 to a sufficient length to connect with the connecting seat 21.

[0035] When the mine car is being loaded, the drive motor 311 drives the output gear 312 to rotate. The rotation of the output gear 312 drives the two transmission gears 313 to rotate synchronously. The rotation of the transmission gears 313 drives the two transmission shafts 314 to rotate synchronously. The rotation of the transmission shafts 314 drives the two drive seats 315 to rotate synchronously. The rotation of the drive seats 315 drives the drive rod 317 to move. The movement of the drive rod 317 drives the universal joint 342 to move. The movement of the universal joint 342 drives the telescopic tube 341 to move and extend. The movement of the telescopic tube 341 causes the connecting block 333 to swing on the mounting bracket 322. The swinging of the connecting block 333 causes the nozzles of the car bucket 11 to swing, thereby causing the nozzles of the car bucket 11 to swing and spray dust suppression mist. The drive rod 317 moves in an ∞-shape, causing the nozzles to swing in an ∞-shape as well. This can cover a wide area without affecting loading. Only a single power device is needed to complete the drive, reducing the number of power devices required.

[0036] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structures made using the contents of the present invention specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of the present invention.
