[0031] Preferably, one side of the first piston 1208 is connected to the locking block 1211 through the first spring 1210, and three airtight grooves 1212 are opened on an inner wall of the first airtight channel 1209, and the three airtight grooves 1212 are evenly spaced on the first airtight channel 1209, the locking block 1211 is snap-connected in one of the airtight grooves 1212, and the second piston 1213 is slidably connected in the three airtight grooves 1212, and in the process of pulling the second water spray channel 1304, the third piston 1302 moves, and in the process of the third piston 1302 crossing the fourth piston 1314, the fourth piston 1314 will be squeezed to move upward, and at this time, the corresponding second piston 1213 will move to the left under the action of pneumatics, so as to squeeze the locking block 1211, so as to facilitate unlocking the first piston 1208, and at the same time, the first piston 1208 will move backward under the action of pneumatics, so as to facilitate adjusting the gear position.

[0032] Preferably, one side of the first circular gear 1204 is meshedly connected with the fourth circular gear 1214, and the front side of the fourth circular gear 1214 is connected to the fifth circular gear 1216 through the second connecting shaft 1215, the front side of the fifth circular gear 1216 is connected to the sixth circular gear 1217 through the second connecting shaft 1215, and a belt transmission assembly 1218 is fixed to the rear side of the fourth circular gear 1214, and the output end of the belt transmission assembly 1218 is connected to the first gear pump 10. When the first circular gear 1204 is meshedly connected with the fourth circular gear 1214, the fourth circular gear 1214 will rotate with the rotation of the first circular gear 1204, and when the second circular gear 1206 is meshedly connected with the fifth circular gear 1216, the fifth circular gear 1216 will rotate with the rotation of the second circular gear 1206. When the third circular gear 1207 is meshed and connected with the sixth circular gear 1217, the sixth circular gear 1217 will rotate with the rotation of the third circular gear 1207. The rotation of the fourth circular gear 1214, the second connecting shaft 1215, the fifth circular gear 1216 and the sixth circular gear 1217 will drive the belt transmission assembly 1218 to operate, thereby driving the first gear pump 10 to rotate, and the second gear pump 11 will rotate accordingly.

The further the first circular gear 1204, the first connecting shaft 1205, the second circular gear 1206, the third circular gear 1207 and the first piston 1208 move backward, the greater the pumping power.

[0033] Preferably, the second water spray channel 1304 and the first water spray channel 7 form a telescopic structure, and the second water spray channel 1304 is fixed to the first water spray channel 7 by a fastener 1305. After rotating the first water spray channel 7 180 degrees, the second water spray channel 1304 can be manually pulled out, so as to increase the dust reduction coverage range conveniently. After adjusting the withdrawal length of the second water spray channel 1304, the fastener 1305 can be used to tighten and fix the second water spray channel 1304.

[0034] Preferably, slide rails 1309 are symmetrically fixed on both sides of an inner wall of the first water spray channel 7, a movable ring 1308 is slidably connected to the slide rails 1309, and the second atomizing nozzle 1310 is arranged one-to-one corresponding to the through hole 1306. In the process of pulling the second water spray channel 1304, the movable ring 1308 slides on the slide rail 1309. After the movable ring 1308 leaves the slide rail 1309, it will automatically bounce down under the action of the second spring 1307, and the second atomizing nozzle 1310 extends into the corresponding through hole 1306. The longer the extension length of the second water spray channel 1304 is, the more second atomizing nozzles 1310 will extend into the corresponding through hole 1306, and a corresponding number of second atomizing nozzles 1310 can be used.

[0035] Preferably, the second airtight channel 1301 is connected to the first airtight channel 1209 through the first connecting pipe 1311, and an airtight groove 1312 is opened at the inner top of the second airtight channel 1301, a third spring 1313 is fixed in the airtight groove 1312, and a fourth piston 1314 is fixed at the bottom of the third spring 1313, the fourth piston 1314 is slidably connected in the airtight groove 1312, and the airtight groove 1312 is connected to the airtight slot 1212 through the second connecting pipe 1315. In the process of pulling the second water spray channel 1304, the third piston 1302 will squeeze the fourth piston 1314 to move upward, and the corresponding second piston 1213 will move to the left, which is convenient for unlocking the first piston 1208.

[0036] When the present invention is used, the self-locking roller 2 is first used to move the device to the desired location and pass water into the water tank 1, and the first water spray channel 7 is rotated 180 degrees. The first circular gear 1204 is initially meshed and connected with the fourth circular gear 1214, and the square shaft 1202 rotates to drive the sleeve 1203 to rotate, and the first circular gear 1204 rotates to drive the fourth circular gear 1214 to rotate, and the belt transmission component 1218 operates to drive the first gear pump 10 to rotate. The first gear pump 10 and the second gear pump 11 are used together to pump water upward, and the water enters the first water spray channel 7. The water is sprayed out through the first atomizing nozzle 8. When the second water spray channel 1304 is manually pulled, the third piston 1302 moves accordingly and passes over the fourth piston 1314. When the fourth piston 1314 moves upward, the corresponding second piston 1213 moves leftward and squeezes the locking block 1211, thereby unlocking the first piston 1208. The first piston 1208 moves backward under the action of pneumatic pressure, thereby adjusting the positions of the sleeve 1203, the first circular gear 1204, the first connecting shaft 1205, the second circular gear 1206 and the third circular gear 1207 as a whole, so as to facilitate the second circular gear 120 6 is meshed and connected with the fifth circular gear 1216 or the third circular gear 1207 is meshed and connected with the sixth circular gear 1217. Since the number of teeth of the first circular gear 1204 is less than the number of teeth of the fourth circular gear 1214, the number of teeth of the second circular gear 1206 is equal to the number of teeth of the fifth circular gear 1216, and the number of teeth of the third circular gear 1207 is greater than the number of teeth of the sixth circular gear 1217, the longer the second water spray channel 1304 is drawn out, the further the first piston 1208 moves backward, and the fourth circular gear 1214, the second connecting shaft 1215, and the fifth circular gear 1217 are meshed and connected. The faster the overall rotation speed of 1216 and the sixth circular gear 1217 is, the greater the pumping power is. In the process of pulling out the second water spray channel 1304, the second atomizing nozzle 1310 leaving the slide rail 1309 will automatically pop down and seal the corresponding through hole 1306. After that, the first atomizing nozzle 8 and the second atomizing nozzle 1310 that pops up can both spray water downward, thereby conveniently increasing the dust reduction coverage range. After pulling out the second water spray channel 1304 of a suitable length, tighten the fasteners 1305 to tightly fix the second airtight channel 1301, and the second water spray channel 1304 is fixed.

[0037] In summary, the present invention achieves the purpose of adjusting the dust reduction coverage and adjusting the water pumping power, and meets people's usage needs.
