DETAILED DESCRIPTION

[0019] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a dust reduction device in a cargo compartment of a truck comprises a cargo compartment railing 101 and a truck 102, wherein the cargo compartment railing 101 is provided with a cargo unloading baffle 103, wherein the cargo unloading baffle 103 and the cargo compartment railing 101 form a cargo compartment chamber, wherein a water tank 201 is provided between the cargo compartment railing 101 and the truck 102, wherein the water tank 201 is fixedly connected to the cargo compartment railing 101, wherein a water filter pipe 202 is fixedly installed in the water tank 201, wherein the other end of the water filter pipe 202 is fixedly installed with a main The main water pump 203 is fixedly connected to the cargo compartment railing 101, a water delivery pipe 204 is fixedly installed on the water outlet of the main water pump 203, a swing box 205 is fixedly installed on the other end of the water delivery pipe 204, a swing reciprocating motor 209 is fixedly installed in the swing box 205, a main swing gear 208 is fixedly installed on the output shaft of the swing reciprocating motor 209, a swing gear ring 207 is meshed and installed on the main swing gear 208, and the swing gear ring 207 is meshed and installed on the swing gear ring 208. 7 is rotatably connected to the water delivery pipe 204, a swiveling mist pipe 206 is fixedly mounted on the swiveling gear ring 207, the swiveling mist pipe 206 is rotatably connected to the cargo compartment railing 101, and a plurality of side atomizing nozzles are arranged on the swiveling mist pipe 206. When the swiveling reciprocating motor 209 is started, the swiveling gear ring 207 and the swiveling mist pipe 206 can be driven to rotate through the main swiveling gear 208, so that the side atomizing nozzles on the swiveling mist pipe 206 can continuously reciprocate, so that the side atomizing nozzles The water mist sprayed from the head can cover the cargo box chamber. At the same time, the device can also be adjusted to expand the rotation range of the side atomizing nozzle to outside the cargo box chamber, so that dust in the cargo box chamber is dispersed everywhere when loading. The end of the swing mist pipe 206 away from the swing box 205 is fixedly rotatably installed with a water distribution pipe 301, and the water distribution pipe 301 is fixedly connected to the cargo box railing 101. A main spray pipe 210 is also fixedly installed on the water distribution pipe 301, and a plurality of main atomizing nozzles are also arranged on the main spray pipe 210.

[0020] like Figures 2 to 4 and Figure 6 As shown, an opening and closing box 302 is fixedly installed on the water distribution pipe 301, and the opening and closing box 302 is fixedly connected to the cargo compartment railing 101. A water distribution chamber 305 is arranged in the opening and closing box 302. One end of the water distribution pipe 301 away from the swinging mist pipe 206 is arranged in the water distribution chamber 305. A water distribution spring 304 is fixedly installed in the water distribution chamber 305. The other end of the water distribution spring 304 is fixedly installed with a water blocking baffle 303, and the water blocking baffle 303 is slidably connected to the water distribution chamber 305. One end of the water blocking baffle 303 is arranged outside the water diversion chamber 305, and the end of the water blocking baffle 303 arranged outside the water diversion chamber 305 is in contact with the unloading baffle 103. In the initial state, the water blocking baffle 303 is in contact with the water diversion pipe 301. In the initial state, the water blocking baffle 303 blocks the outlet of the water diversion pipe 301 arranged in the water diversion chamber 305. Only when the unloading baffle 103 rotates can the water diversion spring 304 push the water blocking baffle 303 to move, so that the water blocking baffle 303 can divert the water diversion pipe 301 to the water diversion chamber 305. The outlet of the water pipe 301 is opened, so that the liquid in the water distribution pipe 301 enters the water distribution chamber 305. A pipe capstan 306 is rotatably installed in the opening and closing box 302. A reset torsion spring is fixedly installed on the pipe capstan 306. The other end of the reset torsion spring is fixedly installed in the opening and closing box 302. The reset torsion spring stores force after the pipe capstan 306 rotates under force. When the pipe capstan 306 is not under force, it returns to the initial position. An intermediate pipe 307 is arranged on the pipe capstan 306. One end of the intermediate pipe 307 is fixedly installed in the water distribution chamber 305, the intermediate pipe 307 is slidably connected to the opening and closing box 302, the intermediate pipe 307 is fixedly connected to the unloading baffle 103, and the end of the intermediate pipe 307 away from the closing box 302 is fixedly installed with a bottom dust reduction pipe 308, and a plurality of bottom atomizing nozzles are arranged on the bottom dust reduction pipe 308. The bottom atomizing nozzle is used to reduce the dust generated during unloading when the unloading baffle 103 rotates during unloading.

[0021] Working principle: When using this device, the water tank 201 must be filled with water first, and then the main water pump 203 is started, and water is injected into the water pipe 204 through the main water pump 203, so that the swinging mist pipe 206 and the main spray pipe 210 can respectively perform dust reduction work in the cargo box chamber through the side atomizing nozzle and the main atomizing nozzle. At the same time, the swinging reciprocating motor 209 is started, so that the swinging reciprocating motor 209 drives the main swinging gear 208 to let the swinging gear ring 207 rotate with the swinging mist pipe 206, thereby increasing the dust reduction range of the side atomizing nozzle. This mode is the mode used when the truck 102 is loaded or moved.

[0022] When the truck 102 dumps the cargo in the cargo box chamber, the cargo in the cargo box sidewall 101 will cause the unloading baffle 103 to rotate relative to the cargo box sidewall 101. At this time, the unloading baffle 103 will release the squeeze on the water blocking baffle 303 after rotating, thereby opening the channel for the water in the water diversion pipe 301 to enter the water diversion chamber 305, so that the water in the water diversion pipe 301 is transmitted to the bottom dust reduction pipe 308 through the water diversion chamber 305 and the intermediate pipe 307, and the bottom dust reduction pipe 308 performs dust reduction treatment on the cargo leaving the cargo box chamber through the bottom atomizing nozzle on the bottom dust reduction pipe 308. In this way, the main atomizing nozzle, the side atomizing nozzle, and the bottom atomizing nozzle are used to reduce dust in the maximum range for the cargo leaving the cargo box chamber, so that the dust spreading range is limited.
