[0016] The beneficial effects of the present invention:

[0017] 1. For a microbial detection and analysis instrument for facilitating slicing analysis according to the present invention, by setting the first motor, rollers, track plate, first mounting plate, and arc-shaped track, the straight toothed plate and the first cutting plate can be in a horizontal state. The toothed plate motor drives the straight toothed plate to move horizontally through the first gear. The straight toothed plate drives the mounting block, the first fixing block, and the first cutting plate to move, so that the first cutting plate cuts the sample on the culture medium. Since the state of the first cutting plate is maintained in a horizontal state, the first cutting plate can uniformly sample the sample on the culture medium, increasing the accuracy of detection; the first motor drives the track plate and the first cutting plate to move along the arc-shaped track through the rollers, thereby adjusting the angle of the first cutting plate. After adjusting to a predetermined angle, repeating the cutting action can cut the sample on the culture medium at different angles, which is very convenient when cutting the sample.

[0018] 2. For a microbial detection and analysis instrument for facilitating slicing analysis according to the present invention, by setting the toothed plate motor, the straight toothed plate, the first motor, and the second motor, when cutting a spherical sample, the straight toothed plate is adjusted to a predetermined position by the toothed plate motor, and then the first motor works to drive the track plate to move along the arc-shaped track, so that the surface of the spherical sample can be uniformly sampled. Compared with manually sampling the spherical sample, the efficiency is higher and the sampling is more uniform.

[0019] 3. For a microbial detection and analysis instrument facilitating slicing analysis according to the present invention, by providing fixing bolts and mounting blocks, when taking multiple samples at different heights, loosen the fixing bolts to separate the mounting blocks from the straight tooth plates, replace the second cutting plate, and then tighten the corresponding fixing bolts. The toothed plate motor drives the straight tooth plate to move, enabling the second cutting plate to cut the samples on the culture medium, thereby slicing the samples into multiple portions at one time and increasing the efficiency of slicing the samples. The third motor drives the vertical shaft to rotate, and through the incomplete gears and half gears arranged at specific positions, multiple second cutting plates are driven to open in a fan shape, thereby taking out the samples in the second cutting plates.

[0020] 4. For a microbial detection and analysis instrument facilitating slicing analysis according to the present invention, by providing a first cutting plate, a rotating motor, and a rotating table, the rotating table drives the arc track to rotate through the mounting rod. The sample is on the first cutting plate. When the rotating table rotates 180°, the first cutting plate is located above the constant temperature water tank. At this time, the first motor and the toothed plate motor work to adjust the angle of the first cutting plate, enabling the sample on the first cutting plate to enter the constant temperature water tank. Then, the first push rod contracts, driving the bent rod and the detection head to descend, bringing the detection head close to the sample for detection, thereby achieving the purpose of automatic sampling and automatic detection, eliminating the need for manual sampling and avoiding the influence of microorganisms in the external environment during manual operation on the detection results.

[0035] As Figures 1-11As shown in the figure, a microbial detection and analysis instrument for facilitating slicing analysis according to the present invention includes a workbench 1 and a cover plate 2. Above the workbench 1, there is an arc-shaped track 3. An orbital plate 5 is installed on the arc-shaped track 3. The orbital plate 5 is installed on the arc-shaped track 3 by rolling with rollers 4. A second mounting plate 7 is installed on the orbital plate 5. A chute is horizontally opened in the middle of the second mounting plate 7. A straight tooth plate 8 is slidably installed in the chute. One end of the straight tooth plate 8 close to the center of the workbench 1 is detachably installed with a first fixing block 17. One end of the first fixing block 17 away from the straight tooth plate 8 is fixedly installed with a first slicing plate 15. The cross-section of the first slicing plate 15 is concave. A cover plate is slidably installed on the top of the first slicing plate 15. A moving bolt 18 is provided on the top of the first fixing block 17. A connecting block 16 is fixedly connected to the top of the cover plate. The other end of the connecting block 16 is connected to the first fixing block 17 through the moving bolt 18. A convex ring is provided on the upper part of the screw rod of the moving bolt 18, and the connecting block 16 is rotatably connected to the convex ring part of the moving bolt 18. A groove is also provided on the top of the workbench 1. A tray 26 is provided in the groove. The culture medium is located in the tray 26. A first mounting plate 6 is fixedly connected to the orbital plate 5. The first mounting plate 6 is rotatably connected to the second mounting plate 7 through a connecting shaft. One end of the first mounting plate 6 away from the second mounting plate 7 is fixedly installed with a second motor 12. One end of the connecting shaft is fixedly connected to the output end of the second motor 12, and the other end is fixedly connected to one side of the second mounting plate 7. One end of the second mounting plate 7 away from the first slicing plate 15 is fixedly installed with a tooth plate motor 9. A first gear 10 is provided at the output end of the tooth plate motor 9. The first gear 10 meshes with the straight tooth plate 8. One end of the straight tooth plate 8 away from the second mounting plate 7 is detachably embedded in a mounting block 13. A threaded groove is provided on the top of the straight tooth plate 8. A fixing bolt 14 is provided on the top of the mounting block 13. The mounting block 13 is connected to the straight tooth plate 8 through the fixing bolt 14. A first push rod 21 is fixedly installed on the workbench 1. A bent rod 22 is fixedly connected to the top of the first push rod 21. A detection head 23 is provided at the bottom of the bent rod 22. Pull out the slide plate 33 outward, and place the sample to be microbially detected on the tray 26. The tray 26 is made of rubber material to increase the friction with the culture medium; the first motor 11 works, drives the orbital plate 5 and the first mounting plate 6 to move to one end of the arc-shaped track 3 through the rollers 4, so that the straight tooth plate 8 and the first slicing plate 15 are in a horizontal state. Then the tooth plate motor 9 works, drives the straight tooth plate 8 to move horizontally through the first gear 10. The straight tooth plate 8 drives the mounting block 13, the first fixing block 17 and the first slicing plate 15 to move, so that the first slicing plate 15 slices the sample on the culture medium. Since the state of the first slicing plate 15 is kept in a horizontal state, the first slicing plate 15 can uniformly sample the sample on the culture medium, increasing the accuracy of the detection.When it is necessary to perform slitting sampling at a certain angle, the first motor 11 works. The roller 4 drives the track plate 5 and the first slitting plate 15 to move along the arc track 3, thereby adjusting the angle of the first slitting plate 15. After adjusting to the predetermined angle, repeating the above actions can cut the samples on the culture medium at different angles, which is very convenient when slitting the samples.

[0036] As a technical optimization scheme of the present invention, a mounting rod 20 is fixedly connected to one side of the top of the arc track 3. The bottom of the mounting rod 20 is fixedly connected to a rotating table 19. The bottom of the rotating table 19 is rotatably connected to the top of the workbench 1. A vertical groove is formed at the bottom of the rotating table 19. A rotating motor 24 is arranged in the vertical groove. The bottom of the rotating motor 24 is in contact with the bottom of the vertical groove. The output end at the top of the rotating motor 24 is fixedly connected to the rotating table 19. A mounting groove 27 is also arranged on the top of the workbench 1. A magnetic stirrer 28 is arranged inside the mounting groove 27. A constant temperature water bath 29 is arranged on the top of the magnetic stirrer 28. The mounting groove 27 and the groove are symmetric along a central line of the vertical groove. A second push rod 25 is arranged in the groove. The bottom of the second push rod 25 is connected to the groove, and the top is connected to the tray 26. After the first slitting plate 15 samples, the rotating motor 24 drives the rotating table 19 to rotate. The sample is on the first slitting plate 15. When the rotating table 19 rotates 180°, the first slitting plate 15 is located above the constant temperature water bath 29. At this time, the first motor 11 and the rack motor 9 work to adjust the angle of the first slitting plate 15, so that the sample on the first slitting plate 15 enters the constant temperature water bath 29. The first push rod 21 contracts, driving the bent rod 22 and the detection head 23 to descend, so that the detection head 23 approaches the sample for detection, thereby achieving the purpose of automatic sampling and automatic detection, without the need for manual sampling, and avoiding the influence of microorganisms in the external environment during manual operation on the detection results.

[0037] As a technical optimization scheme of the present invention, a slide plate groove 32 is formed on the side wall of the groove, and a slide plate 33 is arranged in the slide plate groove 32.

[0038] As a technical optimization scheme of the present invention, an inclined groove 30 is also arranged on the workbench 1. The first slitting plate 15 can be inserted into the inclined groove 30. A heating sheet 31 is arranged in the inclined groove 30. A fluorescence detection hole 42 is arranged on the workbench 1. After the sampling is completed, the first motor 11, the rack motor 9 and the second motor 12 work to adjust the height and angle of the first slitting plate 15, so that the first slitting plate 15 enters the inclined groove 30. The heating sheet 31 heats the first slitting plate 15 to remove the remaining microorganisms on the first slitting plate 15, avoiding adverse effects on the next sampling.

[0039] As a technical optimization solution of the present invention, one end of the straight tooth plate 8 can also be connected to the second fixing block 34. One end of the second fixing block 34 close to the straight tooth plate 8 is also fixedly connected with a mounting block 13. The mounting block 13 is connected to the straight tooth plate 8 through a fixing bolt 14. One end of the second fixing block 34 away from the mounting block 13 is provided with a plurality of second cutting plates 37. One end of the second cutting plate 37 close to the second fixing block 34 is fixedly connected with a connecting rod 36. The other end of the connecting rod 36 is fixedly connected to a rotating shaft 38, and all the connecting rods 36 are connected to the same rotating shaft 38. The rotating shaft 38 is rotatably connected to the second fixing block 34. As a technical optimization solution of the present invention, a vertical shaft 41 is provided on the side of the rotating shaft 38 away from the second cutting plate 37. The vertical shaft 41 is rotatably connected to the second fixing block 34. The top of the second fixing block 34 is fixedly connected with a third motor 35. The output end at the bottom of the third motor 35 is fixedly connected to the top of the vertical shaft 41. A plurality of half gears 39 are provided on the outer side of the rotating shaft 38. The number of half gears 39 is one less than that of the second cutting plates 37. Except for the bottommost second cutting plate 37, the other second cutting plates 37 correspond to the half gears 39 one by one. A plurality of incomplete gears 40 are provided on the outer side of the vertical shaft 41. The incomplete gears 40 on the outer side of the vertical shaft 41 can mesh with the corresponding half gears 39. The bottom of the second cutting plate 37 located above contacts the top of the second cutting plate 37 located below it. When it is necessary to take multiple samples of different heights at one time, the fixing bolt 14 can be unscrewed to separate the mounting block 13 and the straight tooth plate 8. After replacing the second cutting plate 37, the corresponding fixing bolt 14 can be tightened. The tooth plate motor 9 works to drive the straight tooth plate 8 to move, so that the second cutting plate 37 cuts the samples on the culture medium, so that the samples can be cut into multiple portions at one time. Then the third motor 35 drives the vertical shaft 41 to rotate, and drives a plurality of second cutting plates 37 to open in a fan shape through the incomplete gears 40 and half gears 39 arranged at specific positions, so as to take out the samples in the second cutting plates 37. After taking out the samples, the third motor 35 drives the vertical shaft 41, the incomplete gears 40, the half gears 39 and the second cutting plates 37 to reset.

[0040] As a technical optimization solution of the present invention, a first motor 11 is fixedly installed on the track plate 5. An arc-shaped tooth plate is provided on the arc-shaped track 3. The output end of the first motor 11 is provided with an output gear, and the output gear meshes with the arc-shaped tooth plate.

[0041] As a technical optimization solution of the present invention, a set of rollers 4, a track plate 5, a first mounting plate 6, a second mounting plate 7, a straight tooth plate 8, a tooth plate motor 9, a first gear 10, a first motor 11, a second motor 12, a mounting block 13, a fixing bolt 14, a first cutting plate 15, a connecting block 16, a first fixing block 17, and a moving bolt 18 are added to the other end of the arc-shaped track 3. The samples can be operated through two first cutting plates 15, and the cutting efficiency is higher.

[0042] Working principle: The first push rod 21 and the second push rod 25 are both electric push rods.

[0043] During use, first pull out the slide plate 33 outward, place the sample to be subjected to microbial detection on the material tray 26. The material tray 26 is made of rubber to increase the friction with the culture medium. The first motor 11 works, drives the track plate 5 and the first mounting plate 6 to move to one end of the arc track 3 through the roller 4, so that the straight tooth plate 8 and the first cutting plate 15 are in a horizontal state. Then the tooth plate motor 9 works, drives the straight tooth plate 8 to move horizontally through the first gear 10. The straight tooth plate 8 drives the mounting block 13, the first fixing block 17 and the first cutting plate 15 to move, so that the first cutting plate 15 cuts the sample on the culture medium. Since the state of the first cutting plate 15 is kept in a horizontal state, the first cutting plate 15 can evenly sample the sample on the culture medium, increasing the accuracy of detection.

[0044] When it is necessary to perform cutting and sampling at a certain angle, the first motor 11 works, drives the track plate 5 and the first cutting plate 15 to move along the arc track 3 through the roller 4, so as to adjust the angle of the first cutting plate 15. After adjusting to the predetermined angle, repeat the above actions, and the sample on the culture medium can be cut at different angles, which is very convenient when cutting the sample.

[0045] Adjust the position of the material tray 26 through the second push rod 25, so as to adjust the height of the culture medium and the sample, facilitating the cutting and sampling of the first cutting plate 15. By adjusting the moving bolt 18, the positions of the connecting block 16 and the cover plate can be adjusted, so as to adjust the gap between the cover plate and the first cutting plate 15, and further achieve the purpose of adjusting the sampling thickness.

[0046] When cutting a spherical sample, adjust the straight tooth plate 8 to a predetermined position through the tooth plate motor 9, and then the first motor 11 works, driving the track plate 5 to move along the arc track 3, and the surface of the spherical sample can be evenly sampled. Compared with manual sampling of spherical samples, the efficiency is higher and the sampling is more uniform.

[0047] When encountering a sample with relatively high hardness, the straight tooth plate 8 can be adjusted to a vertical state, and then the tooth plate motor 9 works, driving the straight tooth plate 8 and the first cutting plate 15 to cut the sample. Since the bottom of the sample is supported by the second push rod 25 and the material tray 26, the cutting force of the first cutting plate 15 on the sample is greater.

[0048] When it is necessary to take multiple samples of different heights at one time, the fixing bolt 14 can be unscrewed to separate the mounting block 13 from the straight tooth plate 8. After replacing the second cutting plate 37, the corresponding fixing bolt 14 can be tightened. The tooth plate motor 9 works to drive the straight tooth plate 8 to move, so that the second cutting plate 37 cuts the samples on the culture medium, so that the samples can be cut into multiple portions at one time. Then, the third motor 35 drives the vertical shaft 41 to rotate, and drives a plurality of second cutting plates 37 to open in a fan shape through the incomplete gear 40 and the half gear 39 arranged at specific positions, so as to take out the samples in the second cutting plate 37. After taking out the samples, the third motor 35 drives the vertical shaft 41, the incomplete gear 40, the half gear 39 and the second cutting plate 37 to reset.

[0049] After the first cutting plate 15 samples, the rotating motor 24 drives the rotating table 19 to rotate. The rotating table 19 drives the arc track 3 through the mounting rod 20. The roller 4, the track plate 5, the first mounting plate 6, the second mounting plate 7, the straight tooth plate 8, the tooth plate motor 9, the first gear 10, the first motor 11, the second motor 12, the mounting block 13, the fixing bolt 14, the first cutting plate 15, the connecting block 16, the first fixing block 17, and the moving bolt 18 move along with the arc track 3. The sample is on the first cutting plate 15. When the rotating table 19 rotates 180°, the first cutting plate 15 is located above the constant temperature water tank 29. At this time, the first motor 11 and the tooth plate motor 9 work to adjust the angle of the first cutting plate 15, so that the sample on the first cutting plate 15 enters the constant temperature water tank 29. Then, the first push rod 21 contracts, driving the bent rod 22 and the detection head 23 to descend, so that the detection head 23 approaches the sample for detection, thus achieving the purpose of automatic sampling and automatic detection, without the need for manual sampling, and avoiding the influence of microorganisms in the external environment during manual operation on the detection results.

[0050] After the sampling is completed, the first motor 11, the tooth plate motor 9 and the second motor 12 work to adjust the height and angle of the first cutting plate 15, so that the first cutting plate 15 enters the inclined groove 30, and the heating sheet 31 heats the first cutting plate 15 to remove the remaining microorganisms on the first cutting plate 15, avoiding adverse effects on the next sampling.

[0051] The workbench 1 is provided with a fluorescence detection hole 42. When needed, the staff can perform fluorescence detection on the sample to increase the detection method. The existing fluorescence detection technology is relatively mature and will not be elaborated here.
