[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example: Reference Figure 1-Figure 8 An emergency sample conveying device includes a conveying frame 2 and a sample detector 1 arranged on one side of the conveying frame 2.

[0022] In this embodiment, the conveying frame 2 is used to set up a conveying assembly to convey the emergency collected samples to the sample detector 1 for timely detection, thereby accelerating the acquisition of sample analysis results.

[0023] The conveying frame 2 is provided with a conveying component for conveying the sample from the sampling origin to one side of the sample detector 1, and the conveying component is provided with a sample box 15 for placing the sample. The sample box 15 is placed on the upper surface of the separation roller 4, and a sample plate 16 is slidably installed in the sample box 15, and a sample positioning hole 17 is opened in the sample plate 16.

[0024] In this embodiment, a sample box 15 is fitted on the conveying component, a sample plate 16 is slidably arranged in the sample box 15, and a sample positioning hole 17 is opened in the sample plate 16. When in use, the sample is inserted into the sample positioning hole 17 for fixation, and then the sample plate 16 is slidably inserted into the sample box 15 for conveyance.

[0025] The conveying assembly includes two groups of first side plates 3 , between which a conveying shaft is rotatably mounted. The conveying shaft includes two groups of symmetrically arranged separation rollers 4 , which are slidably mounted above the conveying frame 2 .

[0026] In this embodiment, the rotation of the separation roller 4 is used to move the sample box 15 and the samples in the sample box 15 and quickly transport them to the sample detector 1 .

[0027] It should be noted that one end of one group of separation rollers 4 is transmission-connected to a driving device, and two adjacent groups of separation rollers 4 are transmission-connected to realize the transportation of samples.

[0028] A pushing assembly is provided on one side of the conveying assembly, and the pushing assembly is used to push the sample into the sample detector 1 for detection. A reset assembly is provided below the conveying assembly, and the reset assembly is used to transport the empty sample box 15 to the sampling origin.

[0029] In this embodiment, when the sample box 15 is transported to one side of the sample detector 1, there is no need to take and place samples individually. The sample plate 16 and the samples in the sample plate 16 can be pushed into the sample detector 1 by using the pushing assembly. At the same time, the two sets of separation rollers 4 are separated, so that the sample box 15 falls onto the conveying rollers 35 under the separation rollers 4, and is conveyed in the reverse direction to convey the sample box 15 back to the sampling origin.

[0030] An electromagnetic plate 33 is fixedly installed on one side of the outer wall of the sample box 15, and a limit frame 31 is fixedly installed on one end of the conveying frame 2 close to the electromagnetic plate 33. A limit shaft 32 is installed in the limit frame 31, and the limit shaft 32 and the electromagnetic plate 33 are matched.

[0031] Specifically, when the sample box 15 reaches one side of the sample detector 1, the electromagnetic plate 33 is started, so that the electromagnetic plate 33 and the second transmission belt 22 are attracted to limit and fix the sample box 15. At the same time, the pushing assembly is started to push the sample plate 16 into the sample detector 1 for detection; then, the two sets of separation rollers 4 are driven to separate, so as to facilitate the sample box 15 to fall, be transported and reset.

[0032] The conveying assembly also includes four groups of fixed frames 6, each of which is slidably installed with a movable plate 5, the first side plate 3 is fixedly connected between the two groups of movable plates 5, and the first rack 9 is fixedly installed on the lower surface of the movable plate 5. Both sides of the top of the conveying frame 2 are rotatably connected to the transmission shaft 8 through the bearing seat 12, and the first gear 10 is fixedly installed at both ends of the transmission shaft 8. The first gear 10 is meshed with the first rack 9. One group of transmission shafts 8 is centrally provided with a motor 7, and the motor 7 is fixedly installed on one side of the conveying frame 2. A first synchronous pulley 13 is fixedly installed at one end of the transmission shaft 8, and the two groups of first synchronous pulleys 13 are connected through a first transmission belt 14 for transmission.

[0033] In this embodiment, the motor 7 is started to drive the transmission shaft 8 to rotate. The first gears 10 are provided at both ends of the transmission shaft 8. The rotation of the first gear 10 drives the first rack 9 to move toward the two sides of the separation roller 4, thereby pulling the movable plate 5 to slide in the fixed frame 6. Since the first side plate 3 is fixedly connected to the two groups of movable plates 5, the movement of the movable plate 5 can drive the separation roller 4 to separate, providing space for the sample box 15 to fall.

[0034] Specifically, a first synchronous pulley 13 is fixedly installed at one end of the two sets of transmission shafts 8, and the two sets of first synchronous pulleys 13 are connected through a first transmission belt 14. Therefore, starting the motor 7 can drive the two sets of transmission shafts 8 to rotate simultaneously, thereby driving the separation rollers 4 on both sides to separate.

[0035] Specifically, the pushing assembly includes two groups of brackets 19, an internal threaded sleeve is rotatably installed in the bracket 19, the internal threaded sleeve is connected to a screw rod 18, a positioning claw 20 is fixedly installed at one end of the screw rod 18, the positioning claw 20 and the sample plate 16 are matched, a second synchronous pulley 21 is fixedly installed on the surface of the internal threaded sleeve, and the two groups of second synchronous pulleys 21 are connected through a second transmission belt 22.

[0036] In this embodiment, the third synchronous pulley 23 is connected to the surface of the screw rod 18 through the third transmission belt 24. Since the third synchronous pulley 23 is sleeved on the surface of the internal threaded sleeve, the rotation of the third synchronous pulley 23 can drive the internal threaded sleeve to rotate, thereby driving the screw rod 18 to move in the bracket 19. The movement of the screw rod 18 drives the positioning claw 20 to clamp the sample plate 16, thereby following the movement of the screw rod 18 and entering the sample detector 1.

[0037] It should be noted that the support plate 30 is fixedly installed in the fixing frame 6 and is located above the moving plate 5 . The support plate 30 is used to support the transition shaft 27 and the rotating shaft 25 , and does not affect the sliding of the moving plate 5 in the fixing frame 6 .

[0038] A support plate 30 is fixedly installed in the fixed frame 6 near the side of the bracket 19, and a transition shaft 27 is rotatably installed in the support plate 30. A second gear 28 is fixedly installed on the bottom end of the transition shaft 27, and a bevel gear 26 is fixedly installed on the top end of the transition shaft 27. A second rack 29 is fixedly connected to one side of the first side plate 3, and the second rack 29 is meshed with the second gear 28. A rotating shaft 25 is rotatably installed on the support plate 30, and a bevel gear 26 is also fixedly installed on one end of the rotating shaft 25. The two sets of bevel gears 26 are meshed. A third synchronous pulley 23 is also fixedly installed on the rotating shaft 25, and a third synchronous pulley 23 is also fixedly installed on one end of the internal threaded sleeve. The two sets of third synchronous pulleys 23 are connected through the third transmission belt 24.

[0039] In this embodiment, since the movable plate 5 drives the first side plate 3 to move, a second rack 29 is fixedly installed on one side of the first side plate 3. The second rack 29 is used to drive the second gear 28 at one end of the transition shaft 27 to rotate. The second gear 28 drives the bevel gear 26 at the top of the transition shaft 27 to drive the bevel gear 26 at one end of the rotating shaft 25 to rotate, thereby driving the third synchronous pulley 23 at one end of the rotating shaft 25 to rotate, thereby driving the pushing assembly to move.

[0040] The reset assembly includes two groups of second side plates 34 and a conveying roller 35 rotatably installed between the second side plates 34. Both ends of the second side plates 34 are fixedly connected with a cross beam 38. The cross beam 38 and the conveying frame 2 are slidably connected. Both ends of the cross beam 38 are provided with a guide wheel 39. The inner side of the support leg of the conveying frame 2 is fixedly installed with a guide plate 37, and the guide wheel 39 slides in the guide plate 37.

[0041] In this embodiment, after the sample plate 16 is pushed into the sample detector 1, the electromagnetic plate 33 is closed, and the empty sample box 15 falls onto the conveying roller 35. The driving device of the conveying roller 35 is started, and the sample box 15 is conveyed to the sampling origin by the rotation of the conveying roller 35. The sample plate 16 with samples is continuously placed as needed, and the conveying assembly is repeatedly opened.

[0042] Four groups of brackets 36 are symmetrically arranged on both sides of the second side plate 34 . A traction rope 11 is wound around one end of the bracket 36 , and the other end of the traction rope 11 is wound around one end of the transmission shaft 8 .

[0043] It should be noted that, in the present embodiment, a traction rope 11 is simultaneously wound around the transmission shaft 8 and the bracket 36 on both sides of the second side plate 34. While the transmission shaft 8 rotates to drive the separation roller 4 to separate, the traction rope 11 is reeled in by the transmission shaft 8 to drive the conveying roller 35 to rise and receive the sample box 15, so as to avoid gravity impact between the sample box 15 and the conveying roller 35 after the sample box 15 falls and mutual damage. After the sample box 15 falls onto the surface of the conveying roller 35, the transmission shaft 8 is reversed, and the separation roller 4 is brought close to fit. After the conveying roller 35 falls, the sample box 15 is conveyed to the sampling origin. There is no need to wait for the test results, and the sample box 15 can be returned to the sampling origin for continued use, thereby improving the sample conveying efficiency, thereby improving the utilization efficiency of the conveying device.

[0044] During use of the present invention, the sample is first inserted into the sample positioning hole 17 for fixation, and then the sample plate 16 is slidably inserted into the sample box 15, the sample box 15 is placed on the upper surface of the separation roller 4, and the conveying component is started to convey the sample box 15 to the position of the sample detector 1; The motor 7 is started to drive the transmission shaft 8 to rotate. The first gears 10 are arranged at both ends of the transmission shaft 8. The first gear 10 is used to drive the first rack 9 to move toward the two sides of the separation roller 4, thereby pulling the movable plate 5 to slide in the fixed frame 6. Since the first side plate 3 is fixedly connected to the two groups of movable plates 5, the movement of the movable plate 5 can drive the separation roller 4 to separate, providing space for the sample box 15 to fall. The second gear 28 at one end of the transition shaft 27 is driven to rotate by the second rack 29, and the second gear 28 drives the bevel gear 26 at the top of the transition shaft 27 to drive the bevel gear 26 at one end of the rotating shaft 25 to rotate, thereby driving the third synchronous pulley 23 at one end of the rotating shaft 25 to rotate. The third synchronous pulley 23 is sleeved on the surface of the internal thread sleeve. Therefore, the rotation of the third synchronous pulley 23 can drive the internal thread sleeve to rotate, thereby driving the screw 18 to move in the bracket 19. The movement of the screw 18 drives the positioning claw 20 to clamp the sample plate 16, so that it follows the movement of the screw 18 and enters the sample detector 1; When the sample plate 16 is pushed into the sample detector 1, the electromagnetic plate 33 is closed, and while the transmission shaft 8 rotates to drive the separation roller 4 to separate, the transmission shaft 8 is used to reel in the traction rope 11 to drive the conveying roller 35 to rise and receive the empty sample box 15, so as to avoid gravity impact between the sample box 15 and the conveying roller 35 after the sample box 15 falls and causes mutual damage. After the sample box 15 falls onto the surface of the conveying roller 35, the transmission shaft 8 is reversed, the separation roller 4 is brought close to fit, and after the conveying roller 35 falls, the sample box 15 is conveyed to the sampling origin.

[0045] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art. The conveying device of the present invention can be used continuously, avoiding interruption of the use of the conveying device and improving the conveying efficiency; it can make an empty sample box 15 fall onto the conveying roller 35 to convey the sample box 15 without affecting the sample detection in the sample plate 16, further ensuring the full use of the conveying device; the conveying roller 35 is raised to receive the sample box 15, avoiding gravity impact between the sample box 15 and the conveying roller 35 after the sample box 15 falls, thereby damaging each other; and it accelerates the automatic separation of the sample plate 16 and the sample box 15, further improving the use efficiency of the conveying device.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
