[0031] The dust cleaning mechanism 3 includes two air cylinders 301, which can provide installation space and gas storage space. The exteriors of the two air cylinders 301 are respectively fixedly connected to the two sides of the box body 1, and the interior of the air cylinder 301 is slidably connected with a movable plug ring 302, which plays a role of limiting. The top of the movable plug ring 302 is fixedly connected with a ventilation rod 303, and the ventilation rod 303 plays a role of connecting ventilation. The interior of the ventilation rod 303 and the interior of the air cylinder 301 are fixedly connected with a tension spring 1 304, and the tension spring 1 304 can reset the ventilation rod 303. The top of the ventilation rod 303 is fixedly connected with a switch valve 305, and the switch valve 305 plays a role of switching. The top of the switch valve 305 is fixedly connected to A jet head 306 is connected, and the jet head 306 can play the role of exhaust. The bottom of the air cylinder 301 is fixedly connected to a fixed tail cylinder 307, and a ventilation disk 308 is slidably connected to the top of the fixed tail cylinder 307. The bottom of the ventilation disk 308 is fixedly connected to a sliding cylinder 309. The bottom of the ventilation disk 308 is fixedly connected to a tension spring 2 310, and the bottom of the tension spring 2 310 is fixedly connected to the inner bottom end of the fixed tail cylinder 307. The bottom of the fixed tail cylinder 307 is fixedly connected to a ventilation hard pipe 311, and one end of the two ventilation hard pipes 311 away from the fixed tail cylinder 307 is fixedly connected to the outer ends of the connecting head 12, and the sliding cylinder 309 is slidably connected to the bottom end of the fixed tail cylinder 307. 310 is arranged inside the sliding cylinder 309. When the metering box is used, the air pump 2 is started, and the air pump 2 can generate airflow and transmit it through the ventilation pipe 7. At this time, the solenoid valve 8 is opened. After the solenoid valve 8 is opened, the gas will enter the gas distributor 9 through the solenoid valve 8, so as to dissipate heat for the inside of the box body 1. At the same time, since it is discharged from the ventilation window 14, it can prevent dust from entering the inside of the box body 1 from the ventilation window 14. At this time, the electric valve 11 is opened and the exhaust valve 15 is closed. The gas enters the inside of the connecting head 12 through the connecting air pipe 10, and then can enter the inside of the fixed tail cylinder 307 through the ventilation hard pipe 311, so as to push the ventilation disc 308 to move upward. At this time, the tension spring 2 310 can be stretched. Since the ventilation disc 308 has no fixed The fixed tail cylinder 307 blocks the gas, so the gas enters the interior of the air cylinder 301 through the holes on the vent plate 308, and the gas is used to push the movable plug ring 302 and the vent rod 303 upward. When the vent rod 303 moves out of the interior of the air cylinder 301 and makes the nozzle 306 reach the top of the vent window 14, the electric valve 11 is closed and the switch valve 305 is opened, and the gas is ejected through the nozzle 306, so that the dust on the vent window 14 can be blown off. At the same time, as the air pressure inside the air cylinder 301 decreases, the vent rod 303 and the movable plug ring 302 are pulled downward by the action of the tension spring 304, reducing the space between the vent rod 303 and the interior of the air cylinder 301, so that the air pressure inside the air cylinder 301 can be maintained. And because the box body 1 has weight,The jet head 306 is ejecting gas, so the air pressure in the lifting mechanism 4 is not enough to lift the box 1.

[0032] The lifting mechanism 4 includes four bases 401, which can contact the ground. The base 401 is fixedly connected to a connecting column 402 inside, which can play a connecting role. The top of the connecting column 402 is fixedly connected to a limiting ring 403, which can play a limiting role. The outside of the limiting ring 403 is slidably connected to a lifting hollow column 404, which can move upward under the action of air pressure, and then can lift the box 1. The lifting hollow column 404 is slidably connected to the inside of the base 401, and the tops of the four lifting hollow columns 404 are respectively fixedly connected to the bottom of the box 1 At the four corners, the outer side of the base 401 is fixedly connected with a ventilation column 405, and one end of the four ventilation columns 405 away from the base 401 is fixedly connected to the outside of the connecting head 12. When there is water on the ground and the box body 1 needs to be lifted, the exhaust valve 15 and the switch valve 305 are closed, and the air pump 2 is turned on. Gas is generated at the output end of the air pump 2 and transmitted to the inside of the base 401 through the ventilation column 405 on the connecting head 12. At this time, the gas will enter the inside of the connecting column 402, and then the lifting hollow column 404 can be lifted upward by air pressure, and then the box body 1 can be lifted upward by the rise of the lifting hollow column 404 to prevent the bottom of the box body 1 from being soaked in water.

[0033] The cooling and filtering mechanism 5 includes a U-shaped tube 501, which can contain liquid for processing gas. The U-shaped tube 501 is fixedly connected to the outside of the box body 1 on one side of the air pump 2. The outside of the U-shaped tube 501 is fixedly connected with a plurality of heat dissipation fins 502. The heat dissipation fins 502 can accelerate heat dissipation, thereby dissipating the heat of the gas entering the U-shaped tube 501. The other end of the U-shaped tube 501 is fixedly connected with a mounting tube 503, and the mounting tube 503 provides a mounting position. A spring 504 is arranged inside the mounting tube 503. A sliding plate 505 is slidably connected to the inside of the mounting tube 503. An air outlet 506 is opened in the middle of the sliding plate 505, and the air outlet 506 can enter the air. The bottom of the U-shaped tube 501 is fixedly connected with a drain pipe 507, and the drain pipe 507 can discharge liquid. One end of the spring 504 is fixedly connected to the mounting tube 503. When the air pump 2 is turned off, the sliding plate 505 will be reset under the action of the spring 1 504, and then the air outlet 506 can be blocked by the mounting cylinder 503 to prevent the liquid in the U-shaped tube 501 from spilling out when the box 1 shakes.

[0034] The drying mechanism 6 includes a desiccant containing cylinder 601, in which desiccant is contained, both ends of the desiccant containing cylinder 601 are fixedly connected to a fixed seat 602, the outside of the fixed seat 602 is slidably connected to a sliding sleeve 603, a spring 2 604 is fixedly connected between the outside of the fixed seat 602 and the inside of the sliding sleeve 603, and the spring 2 604 can reset the sliding sleeve 603, and a plurality of snap-fit ​​balls 605 are arranged on the outer wall of the fixed seat 602, and a fixed ventilation screw 606 is fixedly connected to the top of one end of the U-shaped tube 501 and the end of the fixed air pipe 16 away from the air pump 2. The fixed vent seat 607 is fixedly connected with a plug-in tube 608 on one side close to the desiccant container 601. The outer wall of the plug-in tube 608 is provided with a snap ring groove 609. The snap ball 605 can be snapped into the snap ring groove 609 and blocked by the sliding sleeve 603, so that the plug-in tube 608 can be installed in the fixed seat 602. The snap ball 605 is snapped into the snap ring groove 609. The fixed seat 602 is fixedly connected with a sealing ring 606 on the inside. The sealing ring 606 can play a sealing role. The plug-in tube 608 is away from the fixed vent seat 607 and is sealed with the sealing ring 606. The outer side of the sealing ring 606 is in contact with each other, the snap-fit ​​ball 605 is located on the inner side of the sliding sleeve 603, and the plug-in tube 608 is arranged inside the fixed seat 602. When disassembling the drying mechanism 6, first slide the sliding sleeve 603 toward the direction of the desiccant containing cylinder 601, and then the spring 2 604 can be compressed. At this time, the snap-fit ​​ball 605 is not blocked by the thicker side of the sliding sleeve 603. At this time, the fixed vent seat 607 is pulled out to the side away from the desiccant containing cylinder 601, and then the plug-in tube 608 can be pulled out of the fixed seat 602, and the snap-fit ​​ball 605 is pulled out of the sliding sleeve 603 away from the desiccant containing cylinder 601. The blocking of one side of the receiving tube 601 prevents the snap-fit ​​ball 605 from falling. During installation, the sliding sleeve 603 is also slid toward the side of the desiccant receiving tube 601, and the plug-in tube 608 is inserted into the interior of the fixing seat 602. At this time, the snap-fit ​​ring groove 609 is located at the snap-fit ​​ball 605. The sliding sleeve 603 is then loosened, and the sliding sleeve 603 is pushed toward the side away from the desiccant receiving tube 601 under the action of the spring 2 604. The snap-fit ​​ball 605 is supported by the thicker side of the snap-fit ​​ball 605, and then the snap-fit ​​ball 605 can be snap-fitted into the snap-fit ​​ring groove 609 to complete the installation of the desiccant receiving tube 601.

[0035] Working principle: When using the metering box, start the air pump 2, the air pump 2 can generate airflow and transmit it through the ventilation pipe 7. At this time, the solenoid valve 8 is opened. After the solenoid valve 8 is opened, the gas will enter the gas distributor 9 through the solenoid valve 8, so as to dissipate heat for the interior of the box body 1. At the same time, since it is discharged from the ventilation window 14, it can prevent dust from entering the interior of the box body 1 from the ventilation window 14. At this time, the electric valve 11 is opened and the exhaust valve 15 is closed. The gas enters the interior of the connecting head 12 through the connecting air pipe 10, and then can enter the interior of the fixed tail cylinder 307 through the ventilation hard pipe 311, so as to push the ventilation disc 308 to move upward. At this time, the tension spring 2 310 can be stretched. Since the ventilation disc 308 is not blocked by the fixed tail cylinder 307, the gas passes through the ventilation disc 308. The hole enters the interior of the air cylinder 301, and the gas is used to push the movable plug ring 302 and the ventilation rod 303 upward. When the ventilation rod 303 moves out of the interior of the air cylinder 301 and makes the nozzle 306 reach the top of the ventilation window 14, the electric valve 11 is closed, and the switch valve 305 is opened, and the gas will be ejected through the nozzle 306, so that the dust on the ventilation window 14 can be blown down. At the same time, as the air pressure inside the air cylinder 301 decreases, the ventilation rod 303 and the movable plug ring 302 are pulled downward under the action of the tension spring 304, reducing the space between the ventilation rod 303 and the interior of the air cylinder 301, so that the air pressure inside the air cylinder 301 can be maintained. Since the box body 1 has weight and the nozzle 306 is ejecting gas, the air pressure in the lifting mechanism 4 is not enough to lift the box body 1.

[0036] When there is water on the ground and the box body 1 needs to be lifted, the exhaust valve 15 and the switch valve 305 are closed, and the air pump 2 is turned on. Gas is generated at the output end of the air pump 2 and transmitted to the inside of the base 401 through the ventilation column 405 on the connector 12. At this time, the gas will enter the inside of the connecting column 402, and then the lifting hollow column 404 can be lifted upward by air pressure. Then, the box body 1 can be lifted upward by the rise of the lifting hollow column 404 to prevent the bottom of the box body 1 from being soaked in water;

[0037] When the air pump 2 is started, the input end of the air pump 2 transmits the suction force to the inside of the U-shaped tube 501 through the exhaust valve 15 and the drying mechanism 6. At this time, the sliding plate 505 is moved to the side close to the air pump 2 under the action of the suction force. At this time, the air outlet 506 is not blocked by the mounting tube 503, so that the gas can be forced to enter the inside of the U-shaped tube 501 from the air outlet 506, and the gas entering the U-shaped tube 501 can be filtered by the liquid in the U-shaped tube 501, and the humid air can be dried by the fixed air pipe 16. When the air pump 2 is turned off, the sliding plate 505 is reset under the action of the spring 1 504, and then the air outlet 506 can be blocked by the mounting tube 503 again to prevent the liquid inside the U-shaped tube 501 from spilling out when the box 1 shakes;

[0038] When disassembling the drying mechanism 6, first slide the sliding sleeve 603 toward the direction of the desiccant container 601, and then compress the spring 2 604. At this time, the snap-in ball 605 is not blocked by the thicker side of the sliding sleeve 603. At this time, pull the fixed vent seat 607 to the side away from the desiccant container 601, and then pull the plug tube 608 out of the fixed seat 602. The snap-in ball 605 is blocked by the side of the sliding sleeve 603 away from the desiccant container 601, so that the snap-in ball 605 will not fall off. During installation, the sliding sleeve 603 is similarly slid toward one side of the desiccant container 601, and the insertion tube 608 is inserted into the interior of the fixing seat 602. At this time, the snap ring groove 609 is located at the snap ball 605. The sliding sleeve 603 is then loosened, and the sliding sleeve 603 is pushed toward the side away from the desiccant container 601 under the action of the spring 2 604. The snap ball 605 is supported by its thicker side, and then the snap ball 605 can be snapped into the snap ring groove 609 to complete the installation of the desiccant container 601.
