A impeller 205 is rotatably connected inside the mounting cylinder 204. The impeller 205 can rotate driven by the air flow. The top of the impeller 205 is fixedly connected with a rotating disc 206 which provides an installation position. The top of the rotating disc 206 is fixedly connected with an air ring 207. The outer side of the air ring 207 is rotatably connected with a rotating collar 208 which prevents the air ring 207 from interfering with other structures when it rotates. The inner side of the fixing sleeve 202 is fixedly connected with a mounting ring 209. The top of the mounting ring 209 is fixedly connected with a fixing outer shell 210 which provides an installation position. A rotating ring 211 is rotatably connected inside the fixing outer shell 210 which can provide an installation position and can rotate inside the fixing outer shell 210. The top of the rotating ring 211 is fixedly connected with a rotating top ring 212 which can provide an installation position and can seal the fixing outer shell 210. The inner top of the rotating ring 211 is fixedly connected with a limiting mounting ring 213 which can rotate inside the fixing outer shell 210 so as to maintain the stability of the rotating ring 211 when it rotates. The top of the rotating top ring 212 and the top of the air ring 207 are both fixedly connected with jet nozzles 214. A ventilation connecting pipe 215 is fixedly connected between the outer side of the rotating collar 208 and the inner side of the fixing outer shell 210 which can play a role in connecting and ventilating. A plurality of ventilation holes 216 are formed inside the rotating ring 211. A plurality of wind blades 217 are fixedly connected to the outer side of the rotating ring 211. The wind blades 217 can drive the rotating ring 211 to rotate driven by the air flow.

The wind blades 217 are arranged inside the fixing outer shell 210. The outer side of the limiting mounting ring 213 is rotatably connected to the inner side of the fixing outer shell 210. One end of the air inlet pipe 221 far away from the mounting cylinder 204 is fixedly connected to the output end of the air pump 301. One side of the connecting ventilation pipe 220 far away from the mounting cylinder 204 penetrates through the outer wall of the cleaning barrel 201. Put the freeze-dried fruit grains into the cleaning barrel 201 through the pipe at the top of the cleaning barrel 201. At this time, start the dust collection mechanism 3,After the dust collection mechanism 3 is started, gas enters the interior of the installation cylinder 204 through the air inlet pipe 221. At this time, due to the entry of the gas, the impeller 205 can be driven to rotate. The rotation of the impeller 205 can drive the rotation of the rotating disk 206. After the rotating disk 206 rotates, it can drive the rotation of the air ring 207. The gas inside the installation cylinder 204 is introduced into the interior of the fixed housing 210 through the connecting ventilation pipe 220, and then it can blow the wind blades 217. The rotation of the wind blades 217 drives the rotation of the rotating ring 211, so that the rotating top ring 212 can be driven to rotate. Therefore, the jet nozzles 214 installed on the top of the rotating top ring 212 and the air ring 207 will rotate, and the rotation directions are opposite. At this time, the gas is introduced into the interior of the air ring 207 through the ventilation holes 216 and the ventilation connecting pipe 215. Therefore, when the gas enters the interior of the fixed housing 210 and drives the wind blades 217 to rotate, it can also eject gas through the jet nozzles 214. The ejected gas can be used to turn over and clean the frozen fruit grains inside the cleaning barrel 201, and at the same time, it can also blow away the dust on the fruit grains.,

[0032] The dust collection mechanism 3 includes an air pump 301. The outside of the air pump 301 is fixedly connected to the outside of the multifunctional particle size and particle shape analyzer 1. The input end of the air pump 301 is fixedly connected with an air extraction connecting pipe 302. The air extraction connecting pipe 302 can play a role in connection. The side of the air extraction connecting pipe 302 away from the air pump 301 is fixedly connected with a pressure box 303. The pressure box 303 can stabilize the air pressure. The outer peripheral top of the multifunctional particle size and particle shape analyzer 1 is fixedly connected with a dust collection box 304. The dust collection box 304 can collect dust. One side of the top of the dust collection box 304 is fixedly connected with a communication pipe 305. The end of the communication pipe 305 away from the dust collection box 304 is fixedly connected with an electromagnetic valve 306. The bottom of the electromagnetic valve 306 is fixedly connected to the top of the pressure box 303. The other end of the top of the dust collection box 304 is fixedly connected with a dust extraction pipe 307. The dust extraction pipe 307 can extract the dust inside the cleaning barrel 201. The end of the dust extraction pipe 307 away from the dust collection box 304 is fixedly connected to the top of the cleaning mechanism 2. The outside of the dust collection box 304 is rotatably connected with a sealed rotating door 308. After the sealed rotating door 308 is opened, it is convenient to take out the dust inside the dust collection box 304. The outside of the pressure box 303 is fixedly connected to the outside of the multifunctional particle size and particle shape analyzer 1. After the air pump 301 is started, the gas inside the pressure box 303 can be extracted through the air extraction connecting pipe 302, and the gas is introduced into the interior of the installation cylinder 204 through the air inlet pipe 221. When the gas in the pressure box 303 is lacking, a suction force will be generated inside the pressure box 303. At this time, the electromagnetic valve 306 is opened, and the air in the dust collection box 304 can be extracted through the communication pipe 305, and then the dust in the cleaning barrel 201 can be inhaled into the interior of the dust collection box 304 through the dust extraction pipe 307, realizing the automatic cleaning of dust.

[0033] The air pressure stabilizing mechanism 4 includes a base pipe 401 which can play a role in installation. The bottom of the base pipe 401 is fixedly connected to the top of the air pressure box 303. The top of the base pipe 401 is fixedly connected with a top pipe 402. A sliding pipe 403 is slidably connected inside the top pipe 402. An air leakage hole 404 is formed at the top of the outer wall of the sliding pipe 403. The top pipe 402 can block the air leakage hole 404. The bottom of the sliding pipe 403 is fixedly connected with a bottom plate 405 which plays a role in limiting. A tension spring 406 is sleeved outside the sliding pipe 403. The tension spring 406 can quickly pull the bottom plate 405 upward after a part of the air pressure is restored, so that the air leakage hole 404 is blocked by the top pipe 402 again. One end of the tension spring 406 is fixedly connected to the inner top end of the base pipe 401, and the other end of the tension spring 406 is fixedly connected to the top of the bottom plate 405. When the air pressure in the air pressure box 303 is too low, the bottom plate 405 will be sucked downward, which can then stretch the tension spring 406 and at the same time enable the sliding pipe 403 to slide downward. When the air leakage hole 404 on the sliding pipe 403 moves into the inside of the base pipe 401, the outside air can be inhaled into the inside of the air pressure box 303 through the sliding pipe 403 and the air leakage hole 404, preventing the air pressure in the air pressure box 303 from being too low.

[0034] The feeding mechanism 6 includes a feeding cylinder 601 which can pre-store freeze-dried fruit grains and also control the amount of fruit grains entering the internal part of the multifunctional particle size and particle shape analyzer 1. The feeding cylinder 601 is fixedly connected to the outer top end of the mounting column 5. A valve 602 is fixedly connected to the bottom of the feeding cylinder 601 to control the switch at the bottom of the feeding cylinder 601. A feed pipe 603 is fixedly connected to the outer top end of the feeding cylinder 601 for connection. A feed bottom pipe 604 is fixedly connected to the bottom of the feed pipe 603. A feed seat 605 is fixedly connected to the bottom of the feed bottom pipe 604. A plurality of feed ports 606 are provided on the outer circumference of the feed seat 605 to facilitate the entry of freeze-dried fruit grains. A suction pipe 607 is fixedly connected to the outer top end of the feeding cylinder 601. An automatic valve 608 is fixedly connected to the bottom of the suction pipe 607. The bottom of the automatic valve 608 is fixedly connected to the top of the air pressure box 303. The bottom of the feed seat 605 is fixedly connected to the top of the disk surface two 219. The top of the feed bottom pipe 604 penetrates through the top of the cleaning barrel 201. A sealing cover is threadedly connected to the top of the feed port 606, and a sealing gasket is arranged inside the sealing cover. When feeding is required after the cleaning is completed, first close the solenoid valve 306 and open the automatic valve 608. At this time, the suction force in the air pressure box 303 will be transmitted to the inside of the feeding cylinder 601 through the suction pipe 607. At this time, the gas inside the feeding cylinder 601 can be pumped away, and then a suction force can be generated inside the feeding cylinder 601. Then, the freeze-dried fruit grains inside the cleaning barrel 201 are pumped into the inside of the feeding cylinder 601 through the feed pipe 603, the feed bottom pipe 604, the feed seat 605, and the feed port 606. When the detection amount is reached inside the feeding cylinder 601, open the valve 602, and the fruit grains enter the inside of the guide hopper 8 through the funnel 7, and then enter the inside of the multifunctional particle size and particle shape analyzer 1 through the guiding of the guide hopper 8 for detection.

[0035] Working principle: Before measuring the particle size of freeze-dried fruits, first put the freeze-dried fruit grains into the cleaning barrel 201 through the pipeline at the top of the cleaning barrel 201. At this time, start the dust collection mechanism 3. After the dust collection mechanism 3 is started, the gas enters the inside of the installation cylinder 204 through the air inlet pipe 221. At this time, due to the entry of the gas, the impeller 205 can be driven to rotate. The rotation of the impeller 205 can drive the rotating disk 206 to rotate. After the rotating disk 206 rotates, the air ring 207 can be driven to rotate. The gas inside the installation cylinder 204 is introduced into the inside of the fixed housing 210 through the connecting ventilation pipe 220, and then the wind blades 217 can be blown. The rotation of the wind blades 217 drives the rotating ring 211 to rotate. Therefore, the rotating top ring 212 can be driven to rotate. Therefore, the jet nozzles 214 installed on the top of the rotating top ring 212 and the air ring 207 will rotate, and the rotation directions are opposite. At this time, the gas is introduced into the inside of the air ring 207 through the ventilation holes 216 and the ventilation connecting pipe 215. Therefore, when the gas enters the inside of the fixed housing 210 and drives the wind blades 217 to rotate, the gas can also be ejected through the jet nozzles 214. The ejected gas can be used to turn over the freeze-dried fruit grains inside the cleaning barrel 201 and can also blow up the dust on the fruit grains;

[0036] After the air pump 301 is started, the gas inside the pressure box 303 can be pumped away through the air extraction connecting pipe 302, and the gas is introduced into the inside of the installation cylinder 204 through the air inlet pipe 221. When the gas in the pressure box 303 is lacking, a suction force will be generated inside the pressure box 303. At this time, the electromagnetic valve 306 is opened, and the air in the dust collection box 304 can be pumped away through the connecting pipe 305. Then, the dust in the cleaning barrel 201 can be sucked into the inside of the dust collection box 304 through the dust extraction pipe 307, realizing the automatic cleaning of dust;

[0037] When the air pressure in the pressure box 303 is too low, the bottom plate 405 will be sucked downward, which can stretch the pull spring 406 and at the same time make the sliding pipe 403 slide downward. When the air leakage hole 404 on the sliding pipe 403 moves into the inside of the base pipe 401, the outside gas can be sucked into the inside of the pressure box 303 through the sliding pipe 403 and the air leakage hole 404 to prevent the air pressure in the pressure box 303 from being too low;

[0038] When it is necessary to load materials after the cleaning is completed, first close the solenoid valve 306 and open the automatic valve 608. At this time, the suction force in the pressure chamber 303 will be transmitted to the inside of the loading cylinder 601 through the suction pipe 607. At this time, the gas inside the loading cylinder 601 can be pumped away, and then a suction force can be generated inside the loading cylinder 601. Then, the frozen fruit grains inside the cleaning barrel 201 are sucked into the inside of the loading cylinder 601 through the feed pipe 603, the feed bottom pipe 604, the feed seat 605 and the feed port 606. When the inside of the loading cylinder 601 reaches the detection amount, open the valve 602, and the fruit grains enter the inside of the guide hopper 8 through the funnel 7, and then enter the inside of the multi-functional particle size and particle shape analyzer 1 through the guiding of the guide hopper 8 for detection.
