Description

Technical Field

[0001] This invention relates to conveying technology, specifically to a conveying device and conveying method for sample preparation and testing. Background Technology

[0002] Conveying systems are mechanisms that minimize human intervention in distribution and transfer. Conveyor belts are the most important means of transporting solid materials over long distances, whether horizontally or at an angle.

[0003] In existing technologies, when samples are transported to a designated location on a conveyor belt for sampling and testing, the conveyor belt needs to stop intermittently for sampling and testing and for the stable placement of the sample tube. This causes the mixed sample to settle over time during long-term transport, reducing the degree of mixing inside the sample tube. Consequently, the sample taken by the sampler cannot accurately represent the sample quality, leading to inaccurate test results. Furthermore, the stirring method used to stir the sample inside the sample tube can easily obstruct the sampler's sampling operation. If the stirring structure is removed after stirring, it can carry away a certain amount of sample, causing differences in sample concentration and affecting the test results. To prevent external environmental factors from adversely affecting the sample during transport, rubber stoppers are often added to the top of the sample tube to seal the opening. However, the rubber stoppers can block the sampler during sampling, requiring manual removal, which is time-consuming and detrimental to work efficiency.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to utilize a transmission gear that rotates during conveyor belt transport, causing a support bucket connected to the transmission gear to rotate the lower end of the sample tube around the center of the transmission gear. This shakes and mixes the sample inside the tube, ensuring proper sampling without affecting the accuracy of the test results. By using a connecting screw, when the squeezing cover moves downwards under the pressure of the sampler, the rotating cover rotates, exposing the upper end of the dust cover. This allows the sampler to penetrate the foil film into the sample tube for sampling, eliminating the need for manual operation, accelerating the sampling process, and improving work efficiency. This invention addresses the problems of sample settling during transport, sample volume reduction due to the removal of the stirring structure, and sample susceptibility to external factors. Therefore, it proposes a conveying device and method for sample preparation and testing.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A conveying device and method for sample preparation and testing includes a conveyor frame. A conveyor belt is rotatably connected to the inner side of the conveyor frame via conveyor rollers. A second hook and loop plate is installed at the middle position of the outer side of the conveyor belt.

[0009] In a preferred embodiment of the present invention, two infrared transmitters are installed on one side of the inner wall of the transmission frame, and infrared receivers are installed on the upper surface of the Velcro plate corresponding to the infrared transmitters. A transmission wheel is rotatably connected to the upper surface of the Velcro plate near the transmission gear plate. A meshing rack is installed on the inner wall of the transmission frame corresponding to the transmission wheel. A transmission box is installed on the upper surface of the Velcro plate at the position corresponding to the transmission wheel. A drive gear is rotatably connected to the lower surface of the transmission box near the meshing rack.

[0010] In a preferred embodiment of the present invention, a clamping frame is provided above the inner sidewall of the support frame, and a plurality of evenly distributed clamping members are provided on the inner sidewall of the clamping frame. Movable boxes are installed in four directions on the outer sidewall of the clamping frame, and spherical grooves are opened inside the movable boxes. A connecting belt is installed on the inner sidewall of the support frame corresponding to the position of the movable box, and a spherical handle is installed on one end of the connecting belt near the movable box. Transmission wheels are installed inside the transmission box on the outer side of the connecting shaft of the first transmission wheel and the drive gear, and the two transmission wheels are connected by transmission belts.

[0011] In a preferred embodiment of the present invention, a dust cover is installed on the upper end of the sample tube, a hole is opened in the middle of the upper surface of the dust cover, a tin foil film is installed on the inner side wall of the hole, a number of evenly distributed limiting frames are installed on one side of the outer side wall of the dust cover, and a rotating chamber is integrally formed on the outer side wall of the dust cover near the limiting frame, and a connecting hole is opened on the lower surface of the interior of the rotating chamber.

[0012] In a preferred embodiment of the present invention, a rotating cover plate is provided above the upper surface of the dust cover. A rotating plate is integrally formed on the outer wall of the rotating cover plate corresponding to the position of the rotating chamber. A connecting screw is installed at the middle position of the upper surface of the rotating cover plate. A return spring is installed on the lower surface of the rotating cover plate corresponding to the outer side of the connecting screw. A pressing cover plate is provided above the upper surface of the rotating cover plate. A positioning hole is opened at the middle position of the upper surface of the pressing cover plate. A limiting plate is integrally formed on the outer wall of the pressing cover plate corresponding to the position of the limiting frame. A limiting rod is installed on the lower surface of the limiting plate corresponding to the position of the limiting frame. A return spring is installed on the outer side of the limiting rod corresponding to the upper part of the limiting frame. A rotating plate is also integrally formed on the outer wall of the pressing cover plate corresponding to the position of the rotating chamber, and the inner side of the rotating plate is threaded.

[0013] In a preferred embodiment of the present invention, the conveying method of the sample preparation and testing conveying device includes the following steps:

[0014] Step 1: Place the sample tube to be tested inside the clamping frame with the same inner diameter as the outer diameter of the sample tube, and ensure that the lower end of the sample tube is accurately placed inside the support bucket. Then, control the clamping parts inside the clamping frame to clamp the sample tube. During the transmission of the Velcro plate by the conveyor belt, the drive gear installed on the transmission box and the meshing rack on the inner wall of the transmission frame mesh with each other and rotate. The rotating meshing rack drives the transmission wheel to rotate through the transmission belt inside the transmission box. The rotating transmission wheel drives the transmission gear disc meshed with the transmission wheel to rotate.

[0015] Step Two: When the Velcro plate is transferred to the position of the first infrared transmitter on the transfer frame, the infrared receiver receives the signal emitted by the first infrared transmitter. The electric push rod on the transmission gear automatically extends, pushing the sliding frame to one side. During the pushing process, the straight slider moves in position inside the straight slide groove as the sliding frame moves. During the movement, the rotating seats connected to both ends of the telescopic rod adjust the angle between the connecting plate and the telescopic rod and the sliding frame and the telescopic rod, respectively. The length of the telescopic rod also changes adaptively during the extension. After the sliding frame moves to one side of the straight slide groove, the sample tube tilts at an angle under the drive of the support bucket. During the rotation of the transmission gear, the tilted sample tube rotates, shaking the sample inside the sample tube.

[0016] Step 3: As the sample tube oscillates under the drive of the transmission gear, when the Velcro plate 1 is at the position of the second infrared transmitter on the transmission frame, the infrared receiver receives the signal emitted by the second infrared transmitter. The electric push rod on the transmission gear automatically retracts and resets. When the sliding frame resets to its initial position, the sample tube remains perpendicular to the transmission gear and is directly below the sampler. When the sampler moves downward, it is inserted into the positioning hole on the extrusion cover. When it moves downward, it pushes the limiting plate to follow. The interaction between the rotating plate on the extrusion cover and the connecting screw causes the connecting screw to rotate. When the connecting screw rotates, the reset spring 1 tightens. The rotating connecting screw drives the rotating cover to rotate around the axis of the connecting screw, causing the rotating cover to rotate away from the top of the dust cover. The sampler can then penetrate the foil film to extract the sample from the inside of the sample tube. After the extraction operation is completed, the sampler moves upward. Under the action of reset spring 1 and reset spring 2, the rotating cover and the extrusion cover automatically reset.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The sample tube is rotated by the drive gear during the transmission of the transmission gear disc via the transmission gear disc. The support bucket connected to the transmission gear disc causes the lower end of the sample tube to rotate around the center of the transmission gear disc, which shakes the sample inside the sample tube to mix the sample. The sample tube automatically resets before reaching the sampler position, without affecting the sampling operation or reducing the amount of sample inside the sample tube, thus improving the accuracy of the test results.

[0019] 2. By using a connecting screw, when the squeeze cover moves downward under the pressure of the sampler, the screw rotates, causing the rotating cover connected to the outside of the screw to rotate, exposing the upper end of the dust cover. This facilitates the sampler penetrating the foil film to the sample tube for sampling. After sampling, as the sampler moves upward, the rotating cover rotates back to cover the upper end of the dust cover under the action of the first return spring, and the squeeze cover returns to its original position under the action of the second return spring. This eliminates the need for manual operation during sampling, speeds up the sampling process, reduces the influence of the external environment, and improves work efficiency.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figure 1-9As shown, a conveying device and method for sample preparation and testing includes a conveyor frame 1. A conveyor belt 2 is rotatably connected to the inner side of the conveyor frame 1 via a conveyor roller. A second hook and loop fastener 34 is installed at the middle position of the outer side of the conveyor belt 2, allowing the first hook and loop fastener 31 to be attached to any position on the second hook and loop fastener 34. The spacing between the first hook and loop fasteners 31 is adjustable. Several evenly distributed first hook and loop fasteners 31 are installed on the second hook and loop fastener 34. A support frame 32 is installed at the middle position of the upper surface of the first hook and loop fastener 31. The support frame 32 can provide support from four directions. A sample tube 5 is arranged at the middle position inside the support frame 32. A groove is formed on the lower surface of the support frame 32, and a smooth groove is formed on the upper surface inside the groove. A transmission gear 310 is rotatably connected at the groove position on the surface of the transmission gear 310. A smooth ring is integrally formed at the smooth groove position on the upper surface of the transmission gear 310. The smooth ring on the transmission gear 310 is fitted into the inner side of the smooth groove for limiting the position of the transmission gear 310 without hindering the automatic rotation of the transmission gear 310. A straight smooth groove 313 is opened at the middle position of the upper surface of the transmission gear 310. A support bucket 311 is provided at the middle position of the upper surface of the transmission gear 310. The inner shape of the support bucket 311 can fit tightly with the lower end of the sample tube 5. A connecting plate is installed on the lower surface of the support bucket 311 at the position corresponding to the straight smooth groove 313. A sliding frame 312 is slidably connected at the position corresponding to the straight smooth groove 313 on the upper surface of the transmission gear 310. A straight slider 319 is integrally formed at the position corresponding to the straight groove 313 on the surface. The straight slider 319 slides inside the straight groove 313. When the straight slider 319 is at one end inside the straight groove 313, the sample tube 5 is perpendicular to the transmission gear disk 310. When the straight slider 319 is at the other end inside the straight groove 313, the sample tube 5 is tilted to the transmission gear disk 310. Electric push rods 314 are installed on both sides of the upper surface of the transmission gear disk 310 at the positions corresponding to the sliding frame 312. A telescopic rod 321 is rotatably connected to the upper surface of the sliding frame 312 at the position corresponding to the connecting plate through a rotating seat 320. Both ends of the telescopic rod 321 are connected to the connecting plate and the sliding frame 312 respectively through the rotating seat 320. Two infrared sensors are installed on one side of the inner wall of the transmission frame 1. During transmission with the conveyor belt 2, the transmitter 33 and infrared receiver 38 generate a signal to extend the electric push rod 314 upon receiving infrared light for the first time, and retract upon receiving infrared light for the second time. Infrared receivers 38 are installed on the side of the upper surface of the Velcro plate 31 corresponding to the infrared transmitter 33. A transmission wheel 39 is rotatably connected to the side of the upper surface of the Velcro plate 31 near the transmission gear disk 310. The transmission wheel 39 and the transmission gear disk 310 are on the same horizontal plane and interlock to rotate. A meshing rack 35 is installed on the inner wall of the transmission frame 1 corresponding to the transmission wheel 39. A transmission box 36 is installed on the upper surface of the Velcro plate 31 at the position corresponding to the transmission wheel 39.A drive gear 37 is rotatably connected to the lower surface of the transmission box 36 near the meshing rack 35. Inside the transmission box 36, transmission wheels are mounted on the outer sides of the connecting shafts corresponding to the transmission wheel 39 and the drive gear 37. The two transmission wheels are connected by a transmission belt. A clamping frame 315 is provided above the inner wall of the support frame 32. Several evenly distributed clamping elements are provided on the inner wall of the clamping frame 315. Movable boxes 316 are installed in four directions on the outer wall of the clamping frame 315. Spherical grooves are formed inside the movable boxes 316. A connecting belt 317 is installed on the inner wall of the support frame 32 at the position corresponding to the movable boxes 316. A spherical handle 318 is installed at the end of the connecting belt 317 near the movable box 316. The spherical handle 318 can rotate at multiple angles within the spherical groove.

[0035] In the prior art, when the sample to be tested is transported on the conveyor belt 2 to the designated position for sampling and testing, the conveyor belt 2 needs to be stopped intermittently for sampling and testing and for the stable placement of the sample tube 5. As a result, the mixed sample is prone to sedimentation over time during the long-term transport process, which reduces the degree of mixing of the sample inside the sample tube 5. This leads to the sample taken by the sampler not being able to accurately represent the sample quality, resulting in inaccurate test results. Furthermore, the stirring method is used to stir the sample inside the sample tube 5. The stirring structure can easily hinder the sampling operation of the sampler. If the stirring structure is removed after stirring, it can easily carry away a certain amount of sample, resulting in differences in sample concentration, which can also affect the test results of the sample.

[0036] After the sample tube 5 to be tested is clamped inside the clamping frame 315, the Velcro plate 31 is transported by the conveyor belt 2. During this process, the drive gear 37 mounted on the transmission box 36 engages with the meshing rack 35 on the inner wall of the transmission frame 1 and rotates. The rotating meshing rack 35 drives the transmission wheel 39 to rotate through the transmission belt inside the transmission box 36. The rotating transmission wheel 39 drives the transmission gear disk 310, which is meshed with the transmission wheel 39, to rotate. The Velcro plate 31 is then transported to the first infrared emitter 33 on the transmission frame 1. When the position is reached, the infrared receiver 38 receives the signal emitted by the first infrared transmitter 33. The electric push rod 314 on the transmission gear plate 310 automatically extends to its maximum length, pushing the sliding frame 312 to one side. During the pushing process, the straight slider 319 moves along the inside of the straight slide groove 313 as the sliding frame 312 moves. During the movement, the rotating seats 320 connected to both ends of the telescopic rod 321 adjust the angle between the connecting plate and the telescopic rod 321 with the sliding frame 312 and the telescopic rod 321, respectively. The length of the telescopic rod 321 is also adjusted. The length adapts to the stretching process. After the sliding frame 312 moves to one side of the straight slide groove 313, the sample tube 5 tilts at an angle under the drive of the support bucket 311. During the rotation of the transmission gear 310, the tilted sample tube 5 is rotated, causing the sample inside the sample tube 5 to shake. During the shaking of the sample tube 5 under the drive of the transmission gear 310, when the Velcro plate 31 is at the position of the second infrared emitter 33 on the transmission frame 1, the infrared receiver 38 receives the signal emitted by the second infrared emitter 33. The electric push rod 314 on the transmission gear 310 automatically retracts and resets. During the transmission of the transmission gear 310 via the transmission belt 2, it is driven by the drive gear 37 to rotate, causing the support bucket 311 connected to the transmission gear 310 to rotate the lower end of the sample tube 5 around the center of the transmission gear 310. This shakes the sample inside the sample tube 5, mixing the sample inside the sample tube 5. The sample tube 5 automatically resets before reaching the sampler position, without affecting the sampling operation or reducing the amount of sample inside the sample tube 5, thus improving the accuracy of the test results.

[0037] Example 2:

[0038] Please see Figure 7 and Figure 10As shown, a dust cover 41 is installed on the upper end of the sample tube 5. The inner diameter of the dust cover 41 is the same as the outer diameter of the sample tube 5. A hole 45 is opened in the middle of the upper surface of the dust cover 41. A tin foil film 46 is installed on the inner wall of the hole 45. Several evenly distributed limiting frames 48 are installed on one side of the outer wall of the dust cover 41. The limiting frames 48 have an upper and lower layer structure. A rotating chamber 47 is integrally formed on the outer wall of the dust cover 41 near the limiting frames 48. A connecting hole is opened on the lower surface of the interior of the rotating chamber 47. A rotating cover plate 42 is provided above the upper surface of the dust cover 41. The dust cover 41, the rotating cover plate 42 and the extrusion cover plate 413 are the same size. A rotating plate 49 is integrally formed on the outer wall of the rotating cover plate 42 corresponding to the position of the rotating chamber 47. A connecting screw 43 is installed in the middle of the upper surface of the rotating plate 49. A connecting screw 43 is installed on the lower surface of the rotating plate 49 corresponding to the position of the rotating chamber 47. A return spring 44 is installed on the outside of the connecting screw 43. A pressing cover 413 is provided above the upper surface of the rotating cover 42. A positioning hole 412 is opened in the middle of the upper surface of the pressing cover 413. A limit plate 411 is integrally formed on the outer wall of the pressing cover 413 corresponding to the position of the limit frame 48. A limit rod 410 is installed on the lower surface of the limit plate 411 corresponding to the position of the limit frame 48. The limit rod 410 is inserted into the inner side of the limit frame 48. A return spring 42 is installed on the outer side of the limit rod 410 corresponding to the upper part of the limit frame 48. The return spring 42 can retract when the pressing cover 413 is pressed down and restore its length when it moves up. A rotating plate 49 is also integrally formed on the outer wall of the pressing cover 413 corresponding to the position of the rotating chamber 47. The inner side of the rotating plate 49 is threaded so that the pressing cover 413 can drive the connecting screw 43 to rotate through the thread when it is pressed down.

[0039] In the prior art, in order to prevent external environmental factors from adversely affecting the sample during the transmission process, a rubber stopper is often added to the upper end of the sample tube 5 to seal the upper opening. The sealing of the rubber stopper causes the sampler to be blocked by the rubber stopper when performing the sampling operation, making it impossible to perform the sampling operation smoothly. The rubber stopper needs to be removed manually, which consumes a lot of time and is not conducive to improving work efficiency.

[0040] When the sliding frame 312 returns to its initial position, the sample tube 5 is perpendicular to the transmission gear plate 310, and the sample tube 5 is directly below the sampler. When the sampler moves downward, it is inserted into the positioning hole 412 on the extrusion cover plate 413. When it moves downward, it pushes the limiting plate 411 to move accordingly. The interaction between the rotating plate 49 on the extrusion cover plate 413 and the connecting screw 43 causes the connecting screw 43 to rotate. When the connecting screw 43 rotates, the reset spring 44 is tightened. The rotating connecting screw 43 drives the rotating cover plate 42 to rotate around the axis of the connecting screw 43, so that the rotating cover plate 42 rotates away from the top of the dust cover 41. The sampler can then penetrate the foil film 46 to extract the sample from inside the sample tube 5. After the sampling operation is completed, the sampler moves upward. Under the action of the first and second reset springs, the rotating cover plate 42 and the squeezing cover plate 413 automatically reset. When the squeezing cover plate 413 moves downward under the squeezing of the sampler, it can drive the connecting screw 43 to rotate, causing the rotating cover plate 42 connected to the outside of the connecting screw 43 to rotate. The upper end of the dust cover 41 is exposed, which facilitates the sampler to penetrate the tin foil film 46 into the sample tube 5 for sampling. After sampling, during the upward movement of the sampler, the rotating cover plate 42 rotates back to cover the upper end of the dust cover 41 under the action of the first reset spring 44, and the squeezing cover plate 413 returns to its original position under the action of the second reset spring. This eliminates the need for manual operation during the sampling process, speeds up the sampling process, and improves work efficiency.

[0041] In use, the sample tube 5 to be tested is placed inside the clamping frame 315 and clamped. During the transmission process driven by the conveyor belt 2, the drive gear 37 mounted on the transmission box 36 engages with the meshing rack 35 on the inner wall of the transmission frame 1, causing it to rotate. The rotating meshing rack 35 drives the transmission wheel 39 to rotate via the transmission belt inside the transmission box 36. The rotating transmission wheel 39 drives the transmission gear disc 310, which is meshed with the transmission wheel 39, to rotate. The Velcro plate 31 is transferred to the first red... When the external transmitter 33 is in position, the infrared receiver 38 receives the signal emitted by the first infrared transmitter 33. The electric push rod 314 on the transmission gear plate 310 automatically extends to its maximum length, pushing the sliding frame 312 to one side. During the pushing process, the straight slider 319 moves within the straight slide groove 313 as the sliding frame 312 moves. During the movement, the rotating seats 320 connected to both ends of the telescopic rod 321 adjust the angle between the connecting plate and the telescopic rod 321 with the sliding frame 312 and the telescopic rod 321, respectively. The length of sample tube 5 adapts to the stretching process. After the sliding frame 312 moves to one side of the straight slide groove 313, the sample tube 5 tilts at an angle under the drive of the support bucket 311. During the rotation of the transmission gear 310, the tilted sample tube 5 rotates, causing the sample inside the sample tube 5 to shake. While the sample tube 5 is shaking under the drive of the transmission gear 310, when the Velcro plate 31 is at the position of the second infrared emitter 33 on the transmission frame 1, the infrared receiver 38 receives the infrared signal emitted by the second infrared emitter 33. The signal causes the electric push rod 314 on the transmission gear 310 to automatically retract and reset. During the transmission of the transmission gear 310 via the transmission belt 2, the drive gear 37 drives the transmission gear 310 to rotate, causing the support bucket 311 connected to the transmission gear 310 to rotate the lower end of the sample tube 5 around the center of the transmission gear 310. This shakes the sample inside the sample tube 5, mixes the sample inside the sample tube 5, and automatically resets before reaching the sampler position. This does not affect the sampling operation and does not reduce the amount of sample inside the sample tube 5, thus improving the accuracy of the detection results.

[0042] When the sliding frame 312 returns to its initial position, the sample tube 5 is perpendicular to the transmission gear plate 310, and the sample tube 5 is directly below the sampler. When the sampler moves downward, it is inserted into the positioning hole 412 on the extrusion cover plate 413. When it moves downward, it pushes the limiting plate 411 to move accordingly. The interaction between the rotating plate 49 on the extrusion cover plate 413 and the connecting screw 43 causes the connecting screw 43 to rotate. When the connecting screw 43 rotates, the reset spring 44 is tightened. The rotating connecting screw 43 drives the rotating cover plate 42 to rotate around the axis of the connecting screw 43, so that the rotating cover plate 42 rotates away from the top of the dust cover 41. The sampler can then penetrate the foil film 46 to extract the sample from inside the sample tube 5. After the sampling operation is completed, the sampler moves upward. Under the action of the first and second reset springs, the rotating cover plate 42 and the squeezing cover plate 413 automatically reset. When the squeezing cover plate 413 moves downward under the squeezing of the sampler, it can drive the connecting screw 43 to rotate, causing the rotating cover plate 42 connected to the outside of the connecting screw 43 to rotate. The upper end of the dust cover 41 is exposed, which facilitates the sampler to penetrate the tin foil film 46 into the sample tube 5 for sampling. After sampling, during the upward movement of the sampler, the rotating cover plate 42 rotates back to cover the upper end of the dust cover 41 under the action of the first reset spring 44, and the squeezing cover plate 413 returns to its original position under the action of the second reset spring. This eliminates the need for manual operation during the sampling process, speeds up the sampling process, and improves work efficiency.

4. A conveying method for a conveying device for sample preparation and testing as described in claim 3, characterized in that, The transport method of the sample preparation and testing transport device includes the following steps: Step 1: Place the sample tube (5) to be tested inside the clamping frame (315) with the same inner diameter as the outer diameter of the sample tube (5), and ensure that the lower end of the sample tube (5) is accurately placed inside the support bucket (311). Then, control the clamping parts inside the clamping frame (315) to clamp the sample tube (5). During the transmission of the Velcro plate (31) on the conveyor belt (2), the drive gear (37) installed on the transmission box (36) and the meshing rack (35) on the inner wall of the transmission frame (1) mesh with each other and rotate. The rotating meshing rack (35) drives the transmission wheel (39) to rotate through the transmission belt inside the transmission box (36). The rotating transmission wheel (39) drives the transmission gear disc (310) meshing with the transmission wheel (39) to rotate. Step 2: When the Velcro plate (31) is transferred to the position of the first infrared transmitter (33) on the transmission rack (1), the infrared receiver (38) receives the signal emitted by the first infrared transmitter (33), and the electric push rod (314) on the transmission gear plate (310) automatically extends, pushing the sliding frame (312) to one side. During the pushing process, the straight slider (319) moves along the inside of the straight slide groove (313) as the sliding frame (312) moves. During the movement, the telescopic rod (321) is connected to the sliding rod. The rotating seats (320) at both ends adjust the angle between the connecting plate and the telescopic rod (321) and the sliding frame (312) and the telescopic rod (321), respectively. The length of the telescopic rod (321) changes adaptively during the stretching process. After the sliding frame (312) moves to one side of the straight slide groove (313), the sample tube (5) tilts under the drive of the support bucket (311). The transmission gear plate (310) drives the tilted sample tube (5) to rotate during the rotation process, shaking the sample inside the sample tube (5). Step 3: During the shaking process of the sample tube (5) driven by the transmission gear plate (310), when the Velcro plate (31) is at the position of the second infrared emitter (33) on the transmission frame (1), the infrared receiver (38) receives the signal emitted by the second infrared emitter (33), and the electric push rod (314) on the transmission gear plate (310) automatically retracts and resets. When the sliding frame (312) is reset to the initial position, the sample tube (5) is perpendicular to the transmission gear plate (310), and the sample tube (5) is just below the sampler. When the sampler moves downward, it is inserted into the positioning hole (412) on the extrusion cover plate (413). When it moves downward, it pushes the limiting plate (411) to follow. As the sampler moves, the interaction between the rotating plate (49) on the squeeze cover (413) and the connecting screw (43) causes the connecting screw (43) to rotate. When the connecting screw (43) rotates, the first reset spring (44) tightens. The rotating connecting screw (43) drives the rotating cover (42) to rotate around the axis of the connecting screw (43). The rotating cover (42) rotates away from the top surface of the dust cover (41) and moves away from the top of the dust cover (41). The sampler can penetrate the tin foil film (46) to the bottom to extract the sample inside the sample tube (5). After the extraction operation is completed, the sampler moves upward. Under the action of the first reset spring (44) and the second reset spring, the rotating cover (42) and the squeeze cover (413) automatically reset.
