[0019] In this embodiment, Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, a storage cylinder 303 is fixed on the inner side of the support frame 301, and a winding rod 304 is rotatably connected inside the storage cylinder 303, a worm gear 305 is fixed on the rear side of the storage cylinder 303, a pull rope 306 is wrapped around the outer side of the winding rod 304, and the head end of the pull rope 306 passes through the bottom of the storage cylinder 303 and is connected to the pulling rod 307, the pulling rod 307 passes through the top of the sampling box 302 and is connected to the piston 309, the rotation of the worm gear 305 can drive the winding rod 304 to rotate, so as to facilitate the automatic retraction and release of the pull rope 306, and when the winding rod 304 rotates to rewind the pull rope 306, the pulling rod 307 and the piston 309 move upward under the pulling action of the pull rope 306.

[0020] In this embodiment, Figure 3 and Figure 4 As shown, a first compression spring 311 is fixed to the top of the airtight groove 310, and the piston 309 is fixed to the bottom of the first compression spring 311. The first compression spring 311 supports the piston 309, thereby assisting the piston 309 to quickly reset.

[0021] In this embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the second sleeve 314 and the first sleeve 312 form a telescopic structure. When the piston 309 moves up and down, it can drive the connecting frame 315, the second sleeve 314 and the hollow orifice plate 316 to move up and down as a whole. At this time, the second sleeve 314 telescopes in the first sleeve 312, and the second sleeve 314 plays a role in limiting the first sleeve 312.

[0022] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a forward and reverse motor 319 is fixed to the inner top of the support frame 301, and the bottom of the forward and reverse motor 319 is connected to the worm 320, and the worm 320 is meshed and connected to the rear side of the worm wheel 305. A screw rod 321 is fixed to the bottom of the worm 320, and the outer side of the screw rod 321 is threadedly connected to the movable frame 322, and the front side of the movable frame 322 is fixed with an extrusion lock rod 323. The worm 320 can rotate under the action of the forward and reverse motor 319, thereby driving the worm wheel 305 to rotate, and the screw rod 321 rotates accordingly, and the movable frame 322 moves up or down, thereby driving the extrusion lock rod 323 to move up or down.

[0023] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a first limiting sleeve 324 is fixed to one side of the sampling box 302, the movable frame 322 passes through the first limiting sleeve 324 and is connected to the movable frame 325, and the movable frame 325 is placed on the outside of the sampling box 302, and a tooth plate 326 is fixed to the bottom of the movable frame 325, and the tooth plate 326 is meshed and connected to the outside of the incomplete gear 317. When the screw rod 321 rotates, the movable frame 322 can move upward or downward under the limiting action of the screw rod 321 and the first limiting sleeve 324, thereby driving the movable frame 325 and the four tooth plates 326 to move upward or downward, thereby driving the four incomplete gears 317 and the sampling plates 318 to rotate, and the four sampling plates 318 are opened or closed. When the four sampling plates 318 are closed, the samples can be gathered and squeezed into the sampling groove 313. Before the samples in the sampling groove 313 are squeezed out, the four sampling plates 318 are opened again.

[0024] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, four incomplete gears 317 are provided, and the four incomplete gears 317 are circumferentially distributed on the sampling box 302. The rotation of the incomplete gears 317 can drive the sampling plate 318 to rotate. The four sampling plates 318 can be used in combination for sampling.

[0025] In this embodiment, Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, a second limiting sleeve 327 is fixed to the top of the sampling box 302, and one side of the second limiting sleeve 327 is connected to the pin 329 through a second compression spring 328. When the pulling rod 307 and the piston 309 move up, the movable frame 322 moves down. When the piston 309 moves to the top, the pin 329 and the second compression spring 328 automatically pop open and get stuck in the slot 308, which is convenient for locking the pulling rod 307 and the piston 309.

[0026] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, a movable plate 330 is fixed to one side of the latch 329, and a through hole 331 is provided on the movable plate 330, and the extruded locking rod 323 is engaged and connected in the through hole 331. The extruded locking rod 323 is initially stuck in the through hole 331, and the movable plate 330 is in a locked state. When the pulling rod 307 and the piston 309 move upward, the movable frame 322 moves downward, and the extruded locking rod 323 moves downward and leaves the through hole 331, so as to facilitate unlocking the movable plate 330. When the piston 309 moves to the top, the latch 329 and the movable plate 330 automatically pop open, and the latch 329 automatically gets stuck in the slot 308, so as to facilitate locking the pulling rod 307.

[0027] The use method and advantages of the present invention: The working process of the sampling device for online detection of refined cotton is as follows: like Figures 1 to 8As shown: First, use external bolts to install the mounting plate 2 on the robotic arm, and the robotic arm moves to position the sampling box 302. After the positioning operation is completed, the electric telescopic column 1 extends, the support frame 301 and the sampling box 302 move downward as a whole, and the sampling plate 318 is inserted into the refined cotton. Then the worm 320 rotates to drive the worm wheel 305 to rotate, and the winding rod 304 rotates the winding rope 306, thereby pulling the pulling rod 307, the piston 309, the connecting frame 315, the second sleeve 314 and the hollow hole plate 316 to move upward as a whole. At the same time, the screw rod 321 rotates with the worm 320, the movable frame 325 and the four tooth plates 326 move downward as a whole, and the four incomplete gears 317 rotate. The four sampling plates 318 rotate and close together to gather and squeeze the sample into the sampling groove 313, thereby completing the sampling operation. When the worm 320 reverses, the movable frame 322 and the squeezing lock rod 323 move up, and the four sampling plates 318 rotate and open. When the squeezing lock rod 323 extends into the through hole 331, it squeezes the movable plate 330 and the latch 329 to move left, thereby unlocking the pull rod 307. The piston 309, the connecting frame 315, the second sleeve 314 and the hollow orifice plate 316 quickly pop open. At the same time, the piston 309 presses the gas in the airtight groove 310 to the hollow orifice plate 316, which facilitates the flushing of the sample and prevents the sample from sticking to the hollow orifice plate 316. Finally, the detection equipment can be used to detect the refined cotton sample.
