[0029] One end of the inner wall of the holding cylinder 201 near the top is fixedly connected to a water injection sleeve 204, and an automatic water adding device 5 is fixed to the outer wall of the detection control console 1. The output end of the automatic water adding device 5 is fixedly connected to a water injection pipe 501, which passes through the closing cover 202 and extends to the inside of the holding cylinder 201, and the water injection pipe 501 is detachably connected to the water injection sleeve 204.

The liquid extraction tube 404 passes through the insertion port 205 to the inner wall of the bottom of the holding cylinder 201, and the connector 405 is snap-connected to the insertion port 205.

[0033] When in use, the lower serrated blade 307 and the upper serrated blade 308 are in a vertical position. During the spraying process, the upper serrated blade 308 cuts in the horizontal direction and the lower serrated blade 307 cuts in the vertical direction. The cutting paths of the two form a cross-shaped three-dimensional space, so that the down feathers can be cut by forces in different directions between the upper and lower serrated blades. Combined with the serrated shape of the crushing blade, it can avoid the phenomenon that the down is easily thrown out of the cutting area due to the rotation of the blades in the same direction, thereby ensuring the contact efficiency and thoroughness of the crushing.

[0034] The inner wall of the inner extraction tube 402 and the inner wall of the cavity of the extraction mounting cylinder 401 at the bottom of the inner extraction tube 402 are both provided with an anti-adhesion layer 407, and a cavity door is clamped at a position corresponding to the outer wall of the extraction mounting cylinder 401 and the cavity at the bottom of the inner extraction tube 402. The cavity at the bottom of the inner extraction tube 402 is connected to the pH meter inside the detection control console 1, and two layers of filter mesh 406 are fixed on the inner wall of the inner extraction tube 402.

[0035] During use, an anti-adhesion layer 407 is provided on the inner wall of the inner extraction tube 402 and the inner wall of the cavity of the extraction mounting cylinder 401 at the bottom of the inner extraction tube 402, and a cavity door is snapped in at a location corresponding to the outer wall of the extraction mounting cylinder 401 and the cavity at the bottom of the inner extraction tube 402, making it easy to open and clean the interior. The cavity at the bottom of the inner extraction tube 402 is connected to the pH meter inside the detection console 1. By providing the anti-adhesion layer 407 inside a space at the bottom of the inner extraction tube 402 and the extraction mounting cylinder 401, it is possible to prevent down and feather debris from being adsorbed on the inner surface of the device during the extraction process, thereby preventing incomplete extraction and affecting the test results.

[0036] Working principle: The detachable barrel bottom 301 is installed on the inner wall of the holding barrel 201 by means of a thread. When the detachable barrel bottom 301 is installed in place, the holding barrel 201 is connected to the rotating platform 105 as a whole. During the connection, the holding barrel 201 can be continuously moved as a whole so that the sleeve end of the crushing blade 302 at the bottom of the detachable barrel bottom 301 is connected to the plug end of the output end of the rotating platform 105. Then the position of the holding barrel 201 is moved so that the holding barrel 201 is clamped with the rotating platform 105. The holding barrel 201 is completely After the body is mounted on the rotating platform 105, the closure cover 202 is pressed down on the top of the holding cylinder 201 and fixed with a snap. The suction pipe is connected to the input end of the vacuum pump suction device 203. The suction speed and weight of the down and feathers sucked by the vacuum pump suction device 203 can be controlled through the electronic display operation screen 101. The suction speed of the vacuum pump suction device 203 is converted into the weight of the down and feathers sucked, thereby sucking the feathers into the holding cylinder 201. After a certain amount of feathers are extracted into the holding tube 201, the pulverizing blade 302 is driven by the rotating table 105 to rotate inside the detachable tube bottom 301 and the holding tube 201 to pulverize the feathers. The automatic water adding device 5 is controlled by the electronic display operation screen 101 to automatically add water. The water is input into the water inlet box 304 through the water injection pipe 501 and the water injection sleeve 204, and is sprayed by the spray nozzle 305. The spray nozzle 305 is fixed to the water inlet box 304 and the cannula 306 is rotatably connected to the bottom of the water injection sleeve 204. During the feather pulverization process, the spray nozzle 305 can be driven to rotate synchronously, so that the down feathers can be evenly sprayed, thereby accelerating the lubrication of the down feathers. Wetting speed: The flow rate of the spray nozzle 305 is selected according to the quality of the down feathers. The speed of water injection into the spray nozzle 305 is controlled by the automatic water adding device 5. During the spraying process, when the two sets of blades rotate simultaneously, the upper serrated blade 308 cuts in the horizontal direction, and the lower serrated blade 307 cuts in the vertical direction. The cutting paths of the two blades form a cross-shaped three-dimensional space, so that the down feathers can be cut by forces in different directions between the upper and lower sets of blades. Combined with the serrated shape of the crushing blade, it can avoid the phenomenon that the down is easily thrown out of the cutting area due to the rotation of the blades in the same direction, thereby ensuring the contact efficiency and thoroughness of the crushing; After the feathers are crushed, the liquid extraction tube 404 is inserted into the holding cylinder 201 through the insertion port 205, so that the end of the liquid extraction tube 404 away from the vacuum pump filtration device 403 is located on the bottom inner wall of the detachable cylinder bottom 301. The liquid extraction tube 404 is fixed to the insertion port 205 via the connector 405. The feather liquid inside the holding cylinder 201 is then drawn into the inner extraction tube 402 for extraction via the vacuum pump filtration device 403. The holding cylinder 201 and the rotating table 105 are detachably connected. After use, by separating the holding cylinder 201 from the rotating table 105 and disconnecting the connection between the end of the crushing blade 302 located at the bottom of the detachable cylinder bottom 301 and the output end of the rotating table 105, the detachable cylinder bottom 301 can be manually rotated to separate the detachable cylinder bottom 301 from the inside of the holding cylinder 201, and at the same time, the insert tube 306 is separated from the water injection sleeve 204, thereby facilitating the cleaning of the holding cylinder 201, the detachable cylinder bottom 301 and the lower serrated blade 307 and the upper serrated blade 308.
