Description

Technical Field

[0001] This invention relates to the field of soil remediation technology for tailings dumps, and in particular to a chemical spraying device for treating tailings dump pollution. Background Technology

[0002] Conventional soil remediation devices typically transport the soil to be remediated into a cleaning unit via a conveyor, where it is cleaned with a remediation agent to alter the soil's properties. This method is unsuitable for waste rock piles containing large volumes of waste rock. Although there are devices that directly spray the remediation agent onto the soil using mobile sprayers, the uneven terrain of the waste rock piles during movement often causes the devices to tilt. This tilting can easily damage the spraying mechanism, requiring the device to be stopped for repair or replacement, thus increasing the remediation time. Summary of the Invention

Detailed Implementation

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

[0024] like Figure 1 and Figure 2As shown, a preferred embodiment of the chemical spraying device for treating tailings pile pollution according to the present invention includes a vehicle body 1, a chemical tank 2, a folding power unit 3, a clutch device 4, a fixed spraying mechanism 5, a movable spraying mechanism 6, and a collision avoidance device 7. The chemical tank 2 is fixed to the vehicle body 1, and the chemical tank is used to store the remediation chemicals. The fixed spraying mechanism 5 is mounted on the vehicle body 1, and is located at the front end of the vehicle body 1. The movable spraying mechanism 6 is rotatably mounted on the vehicle body 1, and is located on both sides of the vehicle body 1. The movable spraying mechanism 6 can be rotated to unfold and fold; when unfolded, the outer end of the movable spraying mechanism 6 is outside the vehicle body 1; when folded, the entire movable spraying mechanism 6 is located on the vehicle body 1. The folding power unit 3 is mounted on the vehicle body 1 and provides power. The clutch device 4 is connected to the folding power unit 3, transmitting power from the folding power unit 3 to the clutch device 4. The clutch device 4 can connect to or disconnect from the movable spraying mechanism 6. When the clutch device 4 is connected to the movable spraying mechanism 6, the power from the folding power unit 3 is transmitted to the movable spraying mechanism 6, driving it to rotate and achieve unfolding or folding. When the clutch device 4 is disconnected from the movable spraying mechanism 6, the movable spraying mechanism 6 can rotate freely. The anti-collision device 7 is rotatably mounted on the movable spraying mechanism 6. When the vehicle body 1 tilts, the anti-collision device 7 supports the movable spraying mechanism 6 to prevent damage from impacts during spraying. The fixed spraying mechanism 5 and the movable spraying mechanism 6 are also connected to the chemical tank 2 via a chemical pipe 81. A water pump 88 is installed on the chemical pipe 81, which pumps the chemical from the chemical tank 2 into the movable spraying mechanism 6 and the fixed spraying mechanism 5. The movable spraying mechanism 6 and the fixed spraying mechanism 5 then spray the chemical onto the waste rock pile. Before spraying, the folding power device 3 drives the clutch device 4, which in turn drives the movable spraying mechanism 6 to rotate and unfold. During spraying, the water pump 88 starts to supply chemical to the fixed spraying mechanism 5 and the movable spraying mechanism 6. Simultaneously, the vehicle body 1 moves with the chemical tank, the fixed spraying mechanism 5, and the movable spraying mechanism 6, thus ensuring that the entire waste rock pile is sprayed. When the vehicle body 1 tilts due to uneven terrain, the anti-collision device 7 supports the movable spraying mechanism 6. The movement of the vehicle body 1 causes the anti-collision device 7 to rotate as it travels on the waste rock, preventing the movable spraying mechanism 6 from colliding with the waste rock or the ground.

[0025] The vehicle body 1 has a mounting platform 11 and a protective cover 12. The medicine tank 2 is fixed to the top surface of the mounting platform 11, and a spray mounting seat 13 is provided on the top surface of the mounting platform 11. The movable spraying mechanism 6 is rotatably mounted on the spray mounting seat 13. The protective cover 12 is installed on the bottom surface of the mounting platform 11, and the protective cover 12 and the mounting platform 11 form a mounting chamber. The clutch device 4 is located in the mounting chamber, which reduces the exposure of parts, improves safety, and also prevents dust.

[0026] like Figure 3 As shown, the folding power device 3 includes a power motor 31, an output bevel gear 32, a transmission bevel gear 33, a power output gear 34, and a power mounting base 35. The power motor 31 is mounted on the mounting platform 11 of the vehicle body 1, and the power mounting base 35 is also mounted on the mounting platform 11 of the vehicle body 1. The transmission bevel gear 33 is mounted on the output shaft of the power motor 31. There are two output bevel gears 32 and two power output gears 34. Both output bevel gears 32 mesh with the transmission bevel gears 33 simultaneously. Each output bevel gear 32 is mounted on the power base via a rotating shaft, and the power output gear 34 is mounted on the rotating shaft. Each rotating shaft mounts one power output gear 34, and the two power output gears 34 are respectively connected to the clutch device 4. The power motor 31 drives the output bevel gear 32 to rotate, the output bevel gear 32 drives the transmission bevel gear 33 to rotate, and the transmission bevel gear 33 drives the power output gear 34 via the rotating shaft. By setting two transmission bevel gears 33 and transmitting power through them, the two power output gears 34 can rotate in opposite directions, ensuring that the two movable spraying mechanisms 6 rotate in opposite directions, thus enabling them to expand or retract synchronously.

[0027] The power mounting base 35 is U-shaped, which allows two transmission bevel gears 33 to be installed in the U-shaped groove, and at the same time allows the power output gear 34 to mesh with the two transmission bevel gears 33 simultaneously.

[0028] like Figure 4As shown, the clutch device 4 includes a clutch driver 41, a rocker arm 42, a clutch input gear 43, a clutch shaft 44, a worm gear 45, and a guide plate 46. The clutch driver 41 is mounted on the protective cover 12 of the vehicle body 1. The clutch driver 41 is connected to the rocker arm 42 and is used to drive the rocker arm 42 to rotate. The clutch driver 41 is a cylinder, but in other embodiments, a hydraulic cylinder or an electric cylinder can also be used. The rocker arm 42 is rotatably mounted on the guide plate 46. In other embodiments, the rocker arm 42 can also be mounted on the mounting platform 11 of the vehicle body 1 or on the protective cover 12. The clutch shaft 44 is rotatably mounted on the rocker arm 42, which drives the clutch shaft 44 to rotate. The axis of rotation of the rocker arm 42 is coaxial with the axis of the power output gear 34. Simultaneously, the clutch shaft 44 is slidably mounted on the guide plate 46, which is mounted on the mounting platform 11 of the vehicle body 1 and guides the rotation of the clutch shaft 44. The clutch input gear 43 is fixed to one end of the clutch shaft 44 and meshes with the power output gear 34. The worm gear 45 is fixed to one end of the clutch shaft 44 and connects to the movable spraying mechanism 6. The power output gear 34 drives the clutch input gear 43 to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the worm gear 45 to rotate, which in turn drives the movable spraying mechanism 6 to rotate. When it is necessary for the worm gear 45 to disengage from the movable spraying mechanism 6, the clutch actuator 41 drives the rocker arm 42 to rotate. The rocker arm 42 drives the clutch shaft 44 to rotate, which in turn drives the worm gear 45 to rotate, thus disengaging the worm gear 45 from the movable spraying mechanism 6 and stopping the supply of power to the movable spraying mechanism 6. Simultaneously, the clutch shaft 44 drives the clutch input gear 43 to move along the outer surface of the power output gear 34, meaning the clutch input gear 43 rotates around the axis of the power output gear 34. When it is necessary to reset the worm gear 45 to reconnect with the movable spraying mechanism 6, the clutch actuator 41 drives the rocker arm 42 to reset. The rocker arm 42 then drives the clutch shaft 44 to reset, which in turn resets the clutch input gear 43 and the worm gear 45, allowing the worm gear 45 to reconnect with the movable spraying mechanism 6. Since the axis of rotation of the rocker arm 42 is coaxial with the axis of the power output gear 34, it can be ensured that the clutch input gear 43 is always engaged with the power output gear 34 during rotation, thereby ensuring that the clutch output gear can be reconnected stably after the direction rotation is reset.

[0029] The guide plate 46 is provided with a guide groove 461, and the clutch shaft 44 is located in the guide groove 461. The guide groove 461 is used to guide the rotation of the clutch shaft 44.

[0030] A drive rod 411 is provided on the output end of the clutch actuator 41. One end of the rocker arm 42 is provided with a drive groove 421, and the drive rod 411 is inserted into the drive groove 421. The other end of the rocker arm 42 is connected to the clutch shaft 44, and the middle part of the rocker arm 42 is mounted on the guide plate 46 via a rotating shaft. The drive groove 421 is strip-shaped, so that the drive rod 411 can slide within the drive groove 421. The clutch actuator 41 drives the drive rod 411 to move up and down, so that the drive rod 411 moves within the drive groove 421, and at the same time drives the rocker arm 42 to rotate, thereby realizing the clutch actuator 41 driving the rocker arm 42 to rotate.

[0031] like Figure 5 As shown, the movable spraying mechanism 6 includes a first spray pipe 61, a first nozzle 62, a worm gear 63, a rotating shaft 64, and a movable seat 65. The rotating shaft 64 is fixed to the worm gear 63, and the rotation of the worm gear 63 drives the rotating shaft 64 to rotate synchronously. The rotating shaft 64 is fixed to the movable seat 65, and both ends of the rotating shaft 64 extend out of the movable seat 65 and are rotatably mounted on the spraying mounting base 13. The rotation of the rotating shaft 64 drives the movable seat 65 to rotate synchronously. The first spray pipe 61 is detachably fixed to the movable seat 65 for easy replacement. The first nozzle 62 is mounted on the first spray pipe 61 and is used to spray pesticides. There are multiple first nozzles 62, which are evenly distributed along the axial direction of the first spray pipe 61 to ensure uniform pesticide spraying. The first spray pipe 61 is connected to the pesticide pipe 81. The water pump 88 pumps the pesticide into the first spray pipe 61 through the pesticide pipe 81, and then sprays it out through the first nozzle 62. When it is necessary to unfold or fold, the worm gear 45 drives the worm wheel 63 to rotate, the worm wheel 63 drives the rotating shaft 64 to rotate, the rotating shaft 64 drives the movable seat 65 to rotate, and the movable seat 65 drives the first nozzle 61 to rotate, so as to realize the unfolding or folding of the first nozzle 61.

[0032] The movable seat 65 is provided with a mounting hole, and the first nozzle 61 is inserted into the mounting hole. The movable seat 65 is provided with a locking hole, and a locking screw is screwed into the locking hole. The locking hole is arranged radially along the mounting hole to ensure that the locking screw can rotate and extend into the mounting hole, thus allowing the locking screw to abut and lock against the first nozzle 61. Alternatively, a screw hole can be provided on the first nozzle 61, allowing the locking screw to be screwed into the screw hole on the first nozzle 61, improving the stability of the connection.

[0033] The fixed spraying mechanism 5 includes a second spray pipe 51 and a second nozzle 52. The second spray pipe 51 is fixedly installed at the front end of the mounting platform 11 of the vehicle body 1. The second nozzle 52 is installed on the second spray pipe 51 and is used to spray the agent. There are multiple second nozzles 52, and the multiple nozzles are arranged at equal intervals along the axial direction of the second spray pipe 51 to ensure that the agent can be sprayed evenly.

[0034] The water pump 88 has an inlet and an outlet. The inlet is connected to the chemical tank 2 via a chemical pipe 81, and the outlet is connected to the movable spraying mechanism 6 via a chemical pipe 81. A replenishment pipe 82 is also connected to the chemical pipe 81. The replenishment pipe 82 is used to introduce external water. The connection between the replenishment pipe 82 and the chemical pipe 81 is located at the front end of the water pump 88, that is, on the side of the water inlet of the water pump 88. A first three-way valve 85 is provided at the connection between the replenishment pipe 82 and the chemical pipe 81. The first three-way valve 85 is used to control the connection between the water pump 88 and the replenishment pipe 82 or the chemical tank 2. The reagent tank 2 is equipped with a level pipe 83, both the upper and lower ends of which are connected to the reagent tank 2. The reagent pipe 81 is also connected to the level pipe 83 via a connecting pipe 84. The connection point between the reagent pipe 81 and the level pipe 83 is located behind the water pump 88, that is, the connection point between the reagent pipe 81 and the level pipe 83 is located on one side of the water outlet end of the water pump 88. A second three-way valve 86 is provided at the connection point between the connecting pipe 84 and the reagent pipe 81. The second three-way valve 86 is used to control the connection between the water pump 88 and the connecting pipe 84 or the movable spraying mechanism 6. A third three-way valve 87 is provided at the connection point between the connecting pipe 84 and the level pipe 83. The third three-way valve 87 is used to control the connection between the upper end of the level pipe 83 and the lower end of the level pipe 83 or the connecting pipe 84. During normal use, that is, when the level pipe 83 is used to display the level of the agent tank 2 and the agent pipe 81 is used to supply agent to the movable spraying mechanism 6, the first three-way valve 85 disconnects the replenishment pipe 82, and the second three-way valve 86 and the third three-way valve 87 both disconnect the connecting pipe 84. When it is necessary to reconfigure the agent, the first three-way valve 85, the second three-way valve 86, and the third three-way valve 87 are all switched, so that the connection between the water pump 88 and the agent tank 2 is disconnected, and the connection between the water pump 88 and the movable spraying mechanism 6 is also disconnected. When the liquid level pipe 83 is opened, the lower end of the liquid level pipe 83 is disconnected from the medicine tank 2, and at the same time, the liquid replenishment pipe 82 is connected to the water pump 88. The two ends of the connecting pipe 84 are connected to the water pump 88 and the liquid level pipe 83 respectively. At this time, the liquid replenishment pipe 82, the connecting pipe 84 and the liquid replenishment pipe 82 form a liquid replenishment channel. In this way, the water pump 88 can use the liquid replenishment pipe 82 to pump the medicine into the water tank through the liquid level pipe 83. One water pump 88 can complete both liquid replenishment and supply, eliminating the need to set up a separate liquid replenishment pump, which can reduce the use of water pump 88.

[0035] The anti-collision device includes a bracket 71 and rollers 72. The bracket 71 is rotatably mounted on the movable nozzle, and three rollers 72 are installed on the bracket 71. This allows the tilting device to roll on the waste rock pile, thereby preventing the movable nozzle from being impacted and protecting it from replacement and maintenance during spraying. In other embodiments, rollers 72 with a larger diameter can be used instead.

[0036] like Figure 6 and Figure 7 As shown, a stirring device 9 is provided on the medicine tank 2. The stirring device 9 is used to stir the medicine in the medicine tank 2 to prevent sedimentation. The stirring device 9 includes a stirring motor 91, a first stirring shaft 92, a second stirring shaft 93, stirring blades 94, and a stirring transmission mechanism 95. The stirring motor 91 is mounted on the medicine tank 2 and serves as a power source. The stirring transmission mechanism 95 is mounted on the medicine tank 2 and is used to transmit power. The first stirring shaft 92 and the second stirring shaft 93 are both rotatably mounted on the stirring transmission mechanism 95, with the first stirring shaft 92 passing through the second stirring shaft 93. The lower end of the first stirring shaft 92 is located outside the second stirring shaft 93. The second stirring shaft 93 is provided with stirring blades 94, and the portion of the first stirring shaft 92 exposed outside the second stirring shaft 93 is fitted with stirring blades 94. The stirring motor 91 drives the first stirring shaft 92 to rotate. The first stirring shaft 92 drives the stirring transmission mechanism 95. The stirring transmission mechanism 95 drives the second stirring shaft 93 to rotate in the opposite direction. The first stirring shaft 92 and the second stirring shaft 93 drive the stirring blades 94 to rotate, which can stir the medicine in the medicine tank 2. The first stirring shaft 92 and the second stirring shaft 93 rotate in opposite directions, which can stir more evenly.

[0037] The stirring transmission mechanism includes a first transmission gear 951, a second transmission gear 952, a third transmission gear 953, and a transmission mounting bracket 954. The first transmission gear 951 is fixed on the first stirring shaft 92 and rotates synchronously with the first stirring shaft 92. The second transmission gear 952 is fixed on the second stirring shaft 93 and rotates synchronously with the second stirring shaft 93. The third transmission gear 953 is rotatably mounted on the transmission mounting bracket 954 and meshes with the first transmission gear 951 and the second transmission gear 952. All three gears are bevel gears. The rotation of the first stirring shaft 92 drives the first transmission gear 951 to rotate, which in turn drives the third transmission gear 953 to rotate. The third transmission gear 953 then drives the second transmission gear 952 to rotate, and the second transmission gear 952 in turn drives the second transmission gear 952 to rotate. This allows for a single power input and enables the first stirring shaft 92 and the second stirring shaft 93 to rotate in opposite directions, resulting in more uniform stirring.

[0038] Before spraying, the movable spraying mechanism 6 is first deployed. Specifically, the power motor 31 drives the output bevel gear 32 to rotate, which in turn drives two transmission bevel gears 33 to rotate. The transmission bevel gears 33 drive the power output gear 34 via a rotating shaft, which in turn drives the clutch input gear 43 to rotate. The clutch input gear 43 drives the rotating shaft to rotate, which in turn drives the worm gear 45 to rotate. The worm gear 45 drives the worm wheel 63 to rotate, which in turn drives the rotating shaft 64 to rotate. The rotating shaft 64 then drives the movable seat 65 to rotate, which in turn drives the first nozzle 61 to rotate, thus deploying the first nozzle 61. Afterward, the clutch device is disconnected from the movable spraying mechanism 6. Specifically, the clutch driver 41 drives the rocker arm 42 to rotate, which in turn drives the clutch shaft 44 to rotate the worm gear 45, causing the worm gear 45 to separate from the worm wheel 63, thereby disconnecting the power to the movable spraying mechanism 6.

[0039] During spraying, the vehicle body 1 moves with the agent tank, fixed spraying mechanism 5 and movable spraying mechanism 6. At the same time, the water pump 88 is started to supply the agent to the fixed spraying mechanism 5 and movable spraying mechanism 6, so that the entire waste rock pile can be sprayed.

[0040] When the vehicle body 1 tilts due to uneven terrain inside the waste rock pile, the anti-collision device 7 supports the movable spraying mechanism 6. When the vehicle body 1 moves, it drives the anti-collision device 7 to rotate and travel on the waste rock, so that the movable spraying mechanism 6 can rotate to avoid hitting the waste rock or the ground.

[0041] 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.
