Description

Technical Field

[0001] This invention relates to the field of dust suppression technology for mining trucks, and in particular to an environmentally friendly dust suppression mining truck. Background Technology

[0002] Dust is easily generated when open-pit mine cars are loading goods and moving. The most common method is to place 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. On the other hand, dump trucks need to move a large range of goods, and the dust suppression equipment cannot suppress dust while the dump trucks are in motion. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an environmentally friendly dust-reducing mining truck that can reduce dust in multiple scenarios.

[0004] To address the aforementioned problems, this invention provides an environmentally friendly dust suppression mining car. The environmentally friendly dust suppression mining car includes a car body, a wheel dust suppression device, a bucket dust suppression device, a water tank, a water pump, and a control valve. The car body has a bucket and wheels. The wheel dust suppression device is mounted on the wheels, the bucket dust suppression device is mounted on the bucket, the water tank is mounted on the car body, and the water pump is located inside the water tank. The water pump is connected to the bucket dust suppression device and the wheel dust suppression device via pipes. The control valve is used to control the pipes to selectively connect the water pump to either the bucket dust suppression device or the wheel dust suppression device.

[0005] Furthermore, the dust suppression device for the truck bed includes a drive unit, a mounting frame, a truck bed sprayer, and a connector. The drive unit is mounted on the truck bed and connected to the connector. The drive unit drives the connector to move in an ∞-shape in the vertical plane. The connector is connected to the truck bed sprayer. The truck bed sprayer is mounted on the mounting frame and can swing left and right and up and down on the mounting frame. The mounting frame is mounted on the truck bed.

[0006] Furthermore, the driving device includes a drive motor, an output gear, a transmission gear, a transmission shaft, a drive housing, a commutator, a drive rod, and a drive box. The drive motor is installed inside the drive box, and the output gear is installed at the output end of the drive motor. The drive motor drives the output gear to rotate. There are two transmission gears and two transmission shafts. The transmission shafts are rotatably installed inside the drive box, and the two transmission shafts are arranged side by side. The two transmission gears are respectively installed on the two transmission shafts. The output gear meshes with one of the transmission gears. The drive rod is located inside the drive housing, and the commutator is installed on the drive box. The commutator is used to guide the drive rod from one drive housing to the other drive housing.

[0007] Furthermore, the drive base includes two drive discs, which are mounted on the transmission shaft at a distance. Each drive disc has a positioning notch, and the drive rod is located within the positioning notch. The drive rod has two positioning parts, which abut against the two drive discs respectively.

[0008] 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.

[0009] 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.

[0010] Furthermore, the wheel dust suppression device includes a connecting seat, a mounting seat, a locking component, a mounting rod, a spray pipe, and an angle synchronization adjuster. The connecting seat is mounted on the wheel of the vehicle body, the mounting seat is rotatably mounted on the connecting seat, the locking component is detachably mounted on the mounting seat, and the locking component is used to open the connecting seat. The mounting rod is mounted on the mounting seat, the spray pipe is mounted on the mounting rod, and the spray pipe is fixed to the mounting rod by fasteners. The spray pipe is used to spray dust suppression mist. There are two spray pipes, located on both sides of the vehicle body wheel, and the angle synchronization adjuster is connected to both spray pipes simultaneously.

[0011] Furthermore, the connecting seat includes a connecting plate and a connecting column. The connecting plate is used for mounting to the wheel, and the connecting column is detachably mounted on the connecting plate. An anti-detachment part is provided inside the connecting column to prevent the mounting seat from falling off. The anti-detachment part is arranged around the inner wall of the connecting column.

[0012] Furthermore, the mounting base includes a plate, a counterweight, and a locking post. The locking post is disposed on the plate and locked inside the connecting post. The counterweight is mounted on the plate. The plate has a screw hole. The locking member is screwed into the screw hole of the plate and inserted into the locking post.

[0013] Furthermore, the angle synchronization adjuster includes pulleys and a synchronization rope. There are two pulleys, which are mounted on two nozzles. The synchronization rope is wound around the two pulleys and is in the shape of an infinity symbol.

[0014] During loading, the control valve of this invention connects a water pump to a dust suppression device in the truck bed. The water pump then pumps water through a pipe into the dust suppression device, which sprays water mist onto the truck bed to suppress dust generated during loading. During transport, the control valve connects a water pump to a wheel dust suppression device, which then pumps water through a pipe into the wheel dust suppression device, which sprays water mist onto the wheels to suppress dust generated during transport. This invention enables targeted dust suppression based on different scenarios, resulting in effective dust reduction. Attached Figure Description

Detailed Implementation

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, a preferred embodiment of the environmentally friendly dust-suppressing mining car of the present invention includes a car body, a wheel dust suppression device 2, a bucket dust suppression device 11, a water tank 4, a water pump 5, and a control valve 6. The wheel dust suppression device 2 is installed on the wheels 12 of the car body and is used to suppress dust generated by the rotation of the wheels 12. The bucket dust suppression device 11 and the water tank 4 are installed on the bucket 11 of the car body. The water pump 5 is located inside the water tank 4 and is connected to the bucket dust suppression device 11 and the wheel dust suppression device 2 via pipes. The control valve 6 controls the pipes, allowing the water pump 5 to selectively connect to either the bucket dust suppression device 11 or the wheel dust suppression device 2. The control valve 6 is a three-way valve, which reduces the number of valves. In other embodiments, the control valve 6 can also use two valves, respectively installed on the pipes connecting the bucket dust suppression device 11 and the wheel dust suppression device 2. During loading, the control valve 6 connects the water pump 5 to the dust suppression device in the truck bed 11. The water pump 5 pumps water through a pipe into the dust suppression device in the truck bed 11, which then sprays water mist onto the truck bed 11 to suppress dust generated during loading. During transport, the control valve 6 connects the water pump 5 to the wheel dust suppression device 2. The water pump 5 pumps water through a pipe into the wheel dust suppression device 2, which then sprays water mist onto the wheels 12 to suppress dust generated during transport.

[0032] like Figures 3 to 5 As shown, the dust suppression device for the truck bed 11 includes a drive unit 31, a mounting frame 32, a truck bed sprayer 33, and a connector 34. The drive unit 31 is mounted on the truck bed 11 and connected to the connector 34. The drive unit 31 drives the connector 34 to move, and the connector 34 is connected to the truck bed sprayer 33. The truck bed sprayer 33 is mounted on the mounting frame 32 and can swing left and right and up and down on the mounting frame 32. The mounting frame 32 is mounted on the truck bed 11. The drive unit 31 drives the connector 34 to move in an ∞-shape in the vertical plane, and the connector 34 drives the truck bed sprayer 33 to swing on the mounting frame 32, enabling the truck bed sprayer 33 to spray forward and backward and swing left and right, achieving basic coverage of the entire truck bed 11 with a single power source, while occupying little space.

[0033] 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 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.

[0034] like Figure 6 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.

[0035] like Figure 7As 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.

[0036] like Figure 8As 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 between the spring 3163 and the bogie and the connection point between the commutator rod 3161 and 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. 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 317... The reversing lever 3161 is driven to tilt to the left, and the spring 3163 is also driven to tilt to the left by the reversing lever 3161. After the driving rod 317 is driven to the reversing lever 3161 by the driving seat 315, the driving rod 317 then moves from the left driving seat 315 to the right driving seat 315. The right driving seat 315 drives the driving rod 317 to rotate counterclockwise, and the driving rod 317 drives the reversing lever 3161 to tilt to the right, returning to the initial position. This cycle repeats, enabling the driving rod 317 to move in an ∞-shape. The spring 3163 keeps the reversing lever 3161 tilted to the right, preventing the reversing lever 3161 from shifting due to vehicle bumps.

[0037] The commutator 3161 is T-shaped, which ensures that the commutator 3161 can be supported by the commutator frame 3162 when it is tilted.

[0038] 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.

[0039] The drive housing 318 has a movable opening 3181, and one end of the drive seat 315 is located at the opening, which facilitates 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, which facilitates the drive motor 311 and the output gear 312 being on the same plane.

[0040] like Figure 9 As shown, the truck bed sprayer 33 includes a truck bed nozzle 11, a connecting pipe 332, and a connecting block 333. 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 block 333, which is rotatably mounted on a mounting frame 32. The connector 34 is connected to the connecting block 333. Specifically, the connecting block 333 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.

[0041] The mounting bracket 32 ​​includes a mounting base 321 and a mounting bracket 322. The mounting base 321 is mounted on the truck bed 11 of the vehicle body. The connector 34 is rotatably mounted on the mounting bracket 322, allowing the connector 34 to rotate in the vertical plane. The mounting bracket 322 is rotatably mounted on the mounting base 321, allowing the mounting bracket 322 to rotate in the horizontal plane, thereby allowing the connector 34 to rotate in the horizontal plane. The mounting bracket 322 is U-shaped, and the shaft 334 of the connecting block 333 is rotatably mounted on the mounting bracket 322.

[0042] 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 block 333 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 block 333.

[0043] like Figure 10 and Figure 11 As shown, the wheel dust suppression device 2 includes a connecting seat 21, a mounting seat 22, a locking member 23, a mounting rod 24, a spray pipe 25, and an angle synchronization adjuster 26. The connecting seat 21 is mounted on the wheel 12 of the vehicle body. The mounting seat 22 is rotatably mounted on the connecting seat 21 and can rotate relative to the connecting seat 21. The center of gravity of the mounting seat 22 is lower than the center of the wheel 12, thus ensuring that the mounting seat 22 will not rotate. The locking member 23 is mounted on the mounting seat 22 and is used to open the connecting seat 21, ensuring that the mounting seat 22 will not fall off the connecting seat 21. The mounting rod 24 is mounted on the mounting base 22, and the nozzle 25 is rotatably mounted on the mounting rod 24. The nozzle 25 is used to spray dust suppression spray. The nozzle 25 is fixed to the mounting rod 24 by fasteners to ensure that the nozzle will not rotate during use. There are two nozzles 25, which are located on both sides of the vehicle wheel 12. Setting two nozzles 25 can ensure that the mounting base 22 can maintain balance and will not rotate when spraying dust suppression spray. The angle synchronization adjuster is connected to two nozzles 25 simultaneously. When one nozzle 25 rotates, the other nozzle 25 rotates in the opposite direction by the same angle. For example, if one nozzle 25 rotates 5° counterclockwise, the other nozzle 25 rotates 5° clockwise, ensuring that both nozzles 25 can rotate synchronously towards or away from the wheel 12. This allows the forces generated by the spraying of dust-suppressing mist from the two nozzles 25 to cancel each other out, achieving a balanced state for the mounting base 22. It should be noted that when adjustment is needed, the fasteners securing the nozzles 25 should be released to allow them to rotate. In other embodiments, the angle synchronization adjuster 26 may be omitted, and adjustment can be performed on a single nozzle 25.

[0044] During the operation of the mining car, the nozzles 25 continuously spray dust-suppressing mist on both sides of the wheels 12. The mist sprayed from the nozzles 25 behind the wheels 12 combines with the dust generated by the wheels 12 and quickly falls back to the ground, effectively reducing dust. Additionally, the nozzles 25 located at the front of the wheels 12 can spray water mist onto the road surface, reducing the possibility of dust being kicked up by the wheels 12 and further reducing dust. Simultaneously, the mounting base 22 is rotatable, ensuring that even when passing over potholes, the nozzles 25 will not come into direct contact with the ground, protecting them from damage. The mounting base 22 is locked to the connecting base 21 by the locking member 23, ensuring that the mounting base 22 will not fall off the connecting base 21 even if the vehicle shakes or vibrates during movement, providing stability and reliability. The mounting base 22 is detachably mounted on the base, allowing for the replacement of the base to accommodate different sized wheels 12, thus reducing the number of parts of varying sizes.

[0045] like Figure 12 As shown, the connecting seat 21 includes a connecting plate 211 and a connecting post 212. The connecting plate 211 is used for mounting to the wheel 12, and the connecting post 212 is detachably mounted on the connecting plate 211. In this embodiment, a screw connection is used. In other embodiments, the connecting post 212 can also be fixed by bolts. The mounting seat 22 is detachably rotatably disposed within the connecting post 212. An anti-detachment part 2121 is provided inside the connecting post 212 to prevent the mounting seat 22 from falling off. The anti-detachment part 2121 is circumferentially disposed on the inner wall of the connecting post 212. The anti-detachment part 2121 is formed by protruding from the inner wall of the connecting post 212 towards the center of the inner cavity, facilitating manufacturing. A guide slope is provided on the side of the anti-detachment part 2121 facing the locking post 223. The guide slope is used to guide the mounting seat 22, facilitating its insertion into the connecting seat 21. A rotary bearing 213 is provided inside the connecting column 212 to facilitate the rotation of the mounting base 22 within the connecting column 212.

[0046] like Figure 13 As shown, the mounting base 22 includes a plate 221, a counterweight 222, and a locking post 223. The locking post 223 is disposed on the plate 221 and is locked inside the connecting post 212. The counterweight 222 is mounted on the plate 221 and is located below the locking post 223. The counterweight 222 is used to lower the center of gravity of the mounting base 22, so that the center of gravity of the mounting base 22 is lower than that of the connecting post 212. In this way, the nozzle 25 on the mounting base 22 can be kept as horizontal as possible, which is not likely to affect the dust suppression effect. At the same time, it will not easily rotate with the connecting base 21, reducing the possibility of the nozzle 25 hitting the bottom surface when the vehicle starts or stops suddenly. The plate 221 is provided with a screw hole, and the locking member 23 is screwed into the screw hole of the plate 221. The locking member 23 is inserted into the snap-fit ​​post 223 to open the snap-fit ​​post 223, thereby snapping the snap-fit ​​post 223 into the connecting post 212.

[0047] The snap-fit ​​post 223 includes a post body 2231 and a snap hook 2232. The post body 2231 is connected to the plate body 221, and the snap hook 2232 is connected to the post body 2231. The snap hook 2232 is used to cooperate with the anti-detachment part 2121 of the connecting post 212. There are multiple snap hooks 2232, which are evenly distributed on the main body. For ease of installation, the snap hook 2232 has a certain degree of elasticity. When not under force, the snap hook 2232 tilts towards the center of the main body, so that the snap hook 2232 can be easily inserted into the connecting post 212. To reduce friction between the hook 2232 and the anti-detachment part 2121, a thrust ball bearing 214 is provided inside the connecting column 212. The thrust ball bearing 214 and the rotary bearing 213 are located on both sides of the anti-detachment part 2121. When the locking member 23 is inserted into the column 2231, the hook 2232 is pushed outward by the locking member 23, so that the end of the hook 2232 abuts against the thrust ball bearing 214, and the middle section of the hook 2232 abuts against the rotary bearing 213. In this way, the rotation is smooth, and the hook 2232 and the column 2231 are not worn.

[0048] The mounting rod 24 is screwed onto the plate 221 of the mounting base 22. To facilitate the installation of the mounting rod 24, a mounting block 27 is provided on the plate 221, and the mounting rod 24 is screwed onto the mounting block 27. The mounting rod 24 is a telescopic rod to accommodate wheels 12 of different sizes.

[0049] like Figure 14 As shown, the angle synchronization adjuster includes pulleys 261 and a synchronization rope 262. There are two pulleys 261 mounted on two nozzles 25. The synchronization rope 262 is wound around the two pulleys 261 in an ∞ shape, ensuring that when one pulley 261 is rotated, the other pulley 261 rotates synchronously in the opposite direction. To increase friction, the synchronization rope 262 is typically made of rubber.

[0050] When the mine car is being loaded, the control valve 6 controls the pipeline to connect the water tank 4 to the dust suppression sprayer 33 in the truck bed. Simultaneously, the drive motor 311 drives the output gear 312 to rotate. The output gear 312 drives two transmission gears 313 to rotate synchronously. The transmission gears 313 drive two transmission shafts 314 to rotate synchronously. The transmission shafts 314 drive two drive seats 315 to rotate synchronously. The drive seats 315 rotate, causing the drive rod 317 to move. The drive rod 317 moves, causing the universal joint 342 to move. The universal joint 342 moves, driving the telescopic tube 341 to move and extend / retract. The telescopic tube 341 moves, causing the connecting block 333 to swing on the mounting bracket 322. The swinging of the connecting block 333 causes the nozzles in the truck bed 11 to swing, thus spraying dust suppression mist. The drive rod 317 moves in an ∞-shape, causing the nozzles to swing in an ∞-shape as well. This provides a wide coverage area without affecting loading; only a single power unit is needed for the drive, reducing the number of power units required.

[0051] After loading is complete, the control valve 6 switches, connecting the water tank 4 to the spray pipe 25 of the wheel dust suppression device 2. The spray pipe 25 sprays dust suppression mist to reduce dust on the wheels 12. The locking member 23 is detachably installed on the mounting base 22, locking the mounting base 22 into the connecting base 21. Removing the locking member 23 allows the mounting base 22 to be removed from the connecting base 21. The detachable mounting base 22 can be installed on the connecting base 21, allowing for the fixing of different types of wheels 12 by replacing the connecting base 21. The two spray pipes 25 are symmetrically arranged, ensuring the stability of the spray pipes 25 and preventing tilting and damage. The installation of the spray pipes 25 on the mounting base 22 lowers the installation position of the spray pipes 25, allowing all the dust suppression mist sprayed from the spray pipes 25 to come into contact with the dust. Compared to the spray installed on the truck bed 11, where some of the mist is carried away by the wind, the dust suppression effect is better. There are nozzles 25 on both sides of the wheel 12, so that the front side of the wheel 12 will spray to wet the bottom surface, which can reduce the dust generated by the wheel 12 and further increase the dust suppression effect.

[0052] 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.
