Description

Technical Field

[0001] This invention relates to the field of testing device technology, and in particular to an automatic beet sampling, juicing and sugar testing device. Background Technology

[0002] As one of my country's important sugar crops, the sugar content in sugar beets is a core indicator for evaluating their quality, directly impacting sugar processing efficiency, finished sugar quality, and the assessment of planting benefits. Therefore, rapid and accurate detection of sugar content in sugar beet roots and tubers is a crucial step in the planting, breeding, harvesting, grading, and processing of sugar beets.

[0003] Chinese patent document CN118883135A discloses an electric portable beet juice extraction device, specifically comprising a cylindrical outer shell and a sampling component disposed at the lower end of the outer shell. The sampling component includes a sampling inner cylinder movably connected to the inner side of the lower end of the outer shell. A sampling cone is provided at the bottom of the sampling inner cylinder. A first through groove is uniformly arranged around the lower side wall of the sampling inner cylinder. An adjusting shaft parallel to the axis of the sampling inner cylinder is rotatably disposed inside the first through groove. This electric portable beet juice extraction device, through the combination of the sampling component and the driving component, can penetrate into the interior of the beet root before cutting and extracting the sample. Electric control of the penetration and rotation slicing avoids the influence of the beet root skin and foreign objects on it. It also allows for slicing and sampling from multiple directions, increasing the sample surface area and facilitating more thorough juice extraction.

[0004] While the existing technology described above possesses the function of automatically pressing juice after sampling and can overcome the influence of the beet root skin and foreign matter on the skin during juicing, there are still some issues. When the sampling cone moves downwards, the bottom of the cone squeezes against the beet, producing juice. Foreign matter mixes into the juice, contaminating the sampling blade. Especially when squeezing against the beet surface, impurities on the skin, such as soil, sand, and pesticide residues, mix into the juice and adhere to the surface of the sampling blade or sampling cone, subsequently adhering to the inside of the beet and indirectly affecting the sugar content determination. Therefore, an automatic beet sampling, juicing, and sugar-measuring device is provided to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic beet sampling, juicing, and sugar testing device to address the shortcomings of existing technologies, thereby solving the technical problem that impurities on the beet skin will be mixed into the sample with the juice during sampling in existing beet juice extraction and sampling devices.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An automatic beet sampling, juicing, and sugar content testing device includes a support frame, which is equipped with a feeding mechanism for placing beet root pieces to be tested, a sampling mechanism for sampling the beet root pieces on the feeding mechanism, a sample placement mechanism for carrying the sample taken out by the sampling mechanism, a juice pressing mechanism for pressing the sample on the sample placement mechanism to extract juice, and a testing mechanism for detecting the sugar content in the juice. The sampling mechanism includes a lifting frame that is movably mounted on a support frame.

The top of the support column is equipped with a first cylinder with a telescopic rod arranged downward and aligned with the lower end of the loading frame. The end of the telescopic rod of the first cylinder is equipped with a pressing block for pressing the beetroot blocks.

[0008] Furthermore, the upper end of the material loading frame is equipped with a horizontally arranged rotating rod that is rotatably connected to the support frame. The support frame is equipped with a second cylinder with its telescopic rod facing upward. The second cylinder is placed below the material loading frame and aligned with its lower end. A first mounting component is installed on the end of the telescopic rod of the second cylinder. A roller is rotatably mounted on the first mounting component. A sliding groove is provided on the bottom surface of the material loading frame.

[0009] Furthermore, the peeling assembly includes a fourth cylinder mounted on the lifting frame. The fourth cylinder is arranged laterally with its telescopic rod facing the lower end of the loading frame. A first fixing member is provided at the end of the telescopic rod of the fourth cylinder. The first fixing member is rotatably provided with a first rotating shaft whose axis is parallel to the telescopic direction of the fourth cylinder's telescopic rod. A drilling tool for removing part of the beet root's outer skin is mounted at the end of the first rotating shaft near the loading frame.

[0010] Furthermore, the cutting assembly includes a fifth cylinder mounted on the lifting frame. The fifth cylinder is arranged laterally with its telescopic rod facing the loading frame. A second fixing member is provided at the end of the telescopic rod of the fifth cylinder. The second fixing member is provided with a sampling tube whose length direction is parallel to the axis of the first rotating shaft and is located directly below the first rotating shaft. A second rotating shaft with its axis parallel to the axis of the first rotating shaft is rotatably arranged inside the sampling tube. A spiral cutter for cutting part of the beetroot pieces is installed at the end of the second rotating shaft near the loading frame. The spiral cutter is located inside the end of the sampling tube near the loading frame. A cutting edge is provided at the end of the sampling tube near the loading frame.

[0011] Furthermore, the sample placement mechanism includes a support block and a sample placement tray mounted on the support block. The sample placement tray is placed directly below the juicing mechanism and is used to place the sample with juice. The edge of the sample placement tray is formed with a drainage groove to guide the juice to the detection mechanism. It also includes a swing arm and a third servo motor mounted on the support frame. One end of the swing arm is fixed to the support block, and the other end of the swing arm is fixed to the output shaft of the third servo motor. A left support platform is provided below the juicing mechanism to support the support block, and a right support platform is provided on the support frame to support the swinging support block.

[0012] Furthermore, the juice pressing mechanism includes a first linear drive module mounted on the support frame and arranged vertically. A sixth cylinder with a telescopic rod arranged downwards is mounted on the movable end of the first linear drive module. A second mounting component is mounted on the end of the telescopic rod of the sixth cylinder, and a juice pressing block for pressing and juicing the sample in the sample tray is provided on the second mounting component.

[0013] Furthermore, the testing mechanism includes a seventh cylinder mounted on a support frame. The seventh cylinder is arranged laterally and has a mounting frame installed on the end of its telescopic rod. The mounting frame is equipped with a sugar content testing device for detecting the sugar content of the juice.

[0014] Furthermore, the support frame is equipped with a cleaning mechanism for cleaning the sample placement mechanism and the detection mechanism. The cleaning mechanism includes a water storage tank and a fixed base installed on the support frame. The fixed base is equipped with a high-pressure water pump. The inlet end of the high-pressure water pump is connected to an inlet pipe connected to the water storage tank. The outlet end of the high-pressure water pump is connected to an outlet pipe. The outlet end of the outlet pipe is equipped with a T-connector. One end of the T-connector is connected to a detection equipment rinsing pipe for rinsing the sugar content detection equipment. The other end of the T-connector is connected to a tray rinsing pipe. The end of the tray rinsing pipe is connected to a rinsing section for rinsing the bottom and side walls of the overturned sample placement tray.

[0015] Furthermore, the rinsing section includes a second linear drive module mounted on a support frame and arranged vertically. A lifting seat is mounted on the movable end of the second linear drive module. A fourth servo motor with its output shaft facing upward is mounted on the lifting seat. A vertically arranged rotating tube is fixedly mounted on the end of the output shaft of the fourth servo motor. The rotating tube is coaxial with the output shaft. Several connecting tubes are arranged equidistantly around the output shaft of the fourth servo motor and connected to the periphery of the rotating tube. The length direction of the connecting tubes is perpendicular to the length direction of the rotating tube. The rinsing section also includes an annular tube whose center point coincides with the center point of the rotating tube and is connected to several connecting tubes. Multiple water spray holes are provided at the top of each connecting tube. Multiple water spray holes are provided at the top and sides of the annular tube. The tray rinsing tube and the rotating tube are connected by a flexible hose.

[0016] The beneficial effects of this invention are as follows: In use, the beetroot pieces to be tested are first placed on the feeding mechanism and fixed. Then, the sampling mechanism is run to sample the fixed beetroot pieces. A small sample is taken and placed on the sample placement mechanism. Subsequently, the juice pressing mechanism is run to press and extract juice from the small sample on the sample placement mechanism. The extracted juice drips onto the detection mechanism, and finally, the sugar content in the juice is detected by the detection mechanism. The sugar content of beetroot pieces is automatically detected through the above process, without the need for staff intervention, thus improving the efficiency of the detection.

[0017] In addition, during the sampling process, the peeling component's actuator is aligned with the beetroot block to be tested. First, the peeling component is run to remove part of the outer skin from the beetroot block. Then, the lifting frame is controlled to move upwards, aligning the cutting component's actuator with the area where the outer skin was removed. The cutting component then cuts out the internal portion of the beetroot block, completing the sampling. Finally, the extracted sample is placed into the sample placement mechanism. By peeling before sampling, impurities on the outer skin, such as soil, sand, and pesticide residues, are prevented from contaminating the sample during sampling, thus avoiding indirect impact on sugar content determination and improving the accuracy of the test.

[0027] The following is a detailed description of an automatic beet sampling, juicing, and sugar measuring device according to the present invention, with reference to the accompanying drawings.

[0028] like Figure 1-2As shown, an embodiment of the automatic beet root sampling, juicing, and sugar content testing device of the present invention includes a support frame 1. The support frame 1 is equipped with a feeding mechanism 2 for placing beet root pieces to be tested, a sampling mechanism 4 for sampling the beet root pieces on the feeding mechanism 2, a sample placement mechanism 3 for carrying the sample taken from the sampling mechanism 4, a juice pressing mechanism 5 for pressing the sample on the sample placement mechanism 3 to extract juice, and a detection mechanism 6 for detecting the sugar content of the extracted juice. Specifically, the beet root pieces to be tested are first placed on the feeding mechanism 2 and fixed. Then, the sampling mechanism 4 is run to sample the fixed beet root pieces. A small sample is taken and placed on the sample placement mechanism 3. Subsequently, the juice pressing mechanism 5 is run to press and extract juice from the small sample on the sample placement mechanism 3. The extracted juice drips onto the detection mechanism 6. Finally, the detection mechanism 6 detects the sugar content in the juice. Through the above process, the sugar content of the beet root pieces is automatically detected without the need for human intervention, thus improving the efficiency of the detection.

[0029] In addition, the support frame 1 is also equipped with a cleaning mechanism 7 for cleaning the sample placement mechanism 3 and the detection mechanism 6. After the beet root pieces on the feeding mechanism 2 are tested, the cleaning mechanism 7 is run to wash away the sample residue remaining on the sample placement mechanism 3. At the same time, it also washes away the residual juice on the detection mechanism 6 to prevent the residue and residual juice from affecting the results of the next beet root piece test. The cleaning mechanism 7 improves the accuracy of sugar measurement of this device.

[0030] like Figure 3-4 As shown, the feeding mechanism 2 includes a support frame 21 mounted on the support frame 1 and a loading frame 22 mounted on the support frame 21. The loading frame 22 is arranged at an inclination and is used to carry the beetroot blocks to be tested. A feeding device (not shown in the figure) for feeding beetroot blocks one by one is provided next to the loading frame 22. After a single beetroot block is placed on the loading frame 22 by the feeding device, the beetroot block will automatically tilt and slide down to the lower end of the loading frame 22 because the loading frame 22 is arranged at an inclination.

[0031] In addition, the feeding mechanism 2 also includes a support column 23 installed on the support frame 1 and located beside the loading frame 22. The top of the support column 23 is equipped with a first cylinder 24 with a telescopic rod facing downwards and aligned with the lower end of the loading frame 22. The end of the telescopic rod of the first cylinder 24 is equipped with a pressing block 25 for pressing the beetroot block. When the beetroot block on the loading frame 22 automatically tilts and slides down to its lower end, the first cylinder 24 is activated, and the telescopic rod extends to push the pressing block 25 to press and fix the beetroot block, preventing the position from changing when the sampling mechanism 4 samples the beetroot block.

[0032] In this embodiment, the upper end of the material frame 22 is equipped with a horizontally arranged rotating rod 26 that is rotatably connected to the support frame 21. By setting the rotating rod 26, the upper end of the material frame 22 can rotate around the horizontally arranged axis. The support frame 21 is equipped with a second cylinder 27 with its telescopic rod facing upward. The second cylinder 27 is located directly below the material frame 22 and aligned with its lower end. A first mounting member 28 is installed on the end of the telescopic rod of the second cylinder 27, and a roller 29 is rotatably mounted on the first mounting member 28. After the beetroot chunks in the loading frame 22 have been inspected, the second cylinder 27 is activated, and the telescopic rod extends upward, causing the roller 29 to move upward. This pushes the lower end of the loading frame 22 upward, causing the loading frame 22 to rotate around the rotating rod 26. At the same time, the roller 29 rolls on the bottom surface of the loading frame 22. When the lower end of the loading frame 22 rotates to be higher than the other end, the beetroot chunks in the loading frame 22 automatically slide out and fall to the designated location for collection, realizing automatic unloading of the beetroot chunks. After unloading, the second cylinder 27 moves the roller 29 downward, and the loading frame 22 rotates in the opposite direction to reset under its own gravity, so as to receive the next beetroot chunk to be inspected.

[0033] Furthermore, a groove 210 is provided on the bottom surface of the material frame 22. When the roller 29 pushes the end of the material frame 22 at the lower position upward, it will slide in the groove 210. By setting the groove 210, the roller 29 is limited and guided.

[0034] like Figure 5-6 As shown, the sampling mechanism 4 includes a lifting frame 41 that is vertically movable on the support frame 1. The support frame 1 is equipped with several third cylinders 42 with telescopic rods arranged upwards. The ends of the telescopic rods of the third cylinders 42 are all fixedly installed with the lifting frame 41. By operating the third cylinders 42, the lifting frame 41 can be controlled to move up and down. The lifting frame 41 is equipped with a peeling component for removing part of the outer skin of the beetroot block to be tested, and a cutting component for cutting a portion of the sample after removing part of the outer skin. The peeling component and the cutting component are arranged vertically. In the initial state, the actuating end of the peeling component is aligned with the beetroot block to be tested. The peeling component is run first to remove part of the outer skin from the surface of the beetroot block to be tested. Then, the lifting frame 41 is controlled to move upwards so that the actuating end of the cutting component is aligned with the position where the outer skin of the beetroot block has been removed. The cutting component is run to cut a portion of the beetroot block, completing the sampling of the beetroot block. Finally, the extracted sample is placed into the sample placement mechanism 3.

[0035] In this embodiment, the peeling assembly includes a fourth cylinder 43 mounted on the lifting frame 41. The fourth cylinder 43 is arranged laterally with its telescopic rod facing the lower end of the loading frame 22. A first fixing member 44 is provided at the end of the telescopic rod of the fourth cylinder 43. The first fixing member 44 is rotatably equipped with a first rotating shaft 45 whose axis is parallel to the telescopic direction of the telescopic rod of the fourth cylinder 43. A drilling tool 46 for removing part of the beetroot block's skin is mounted at one end of the first rotating shaft 45 near the loading frame 22. When the beetroot block is fixed, the fourth cylinder 43 is operated, and the telescopic rod extends towards the beetroot block, thereby bringing the first rotating shaft 45 and the drilling tool 46 closer to the beetroot block. When the drilling tool 46 contacts the skin of the beetroot block, the first rotating shaft 45 is controlled to rotate. During the rotation, the telescopic rod of the fourth cylinder 43 continues to extend, thus removing part of the beetroot block's skin. The drilling tool 46 can be a spiral tool or a drill bit. Removing part of the skin is to prevent impurities on the skin, such as soil, sand, and pesticide residues, from mixing into the sample during sampling, thereby indirectly affecting the determination of sugar content.

[0036] To control the rotation of the first rotating shaft 45, a first servo motor 47 is mounted on the first fixing member 44. The output shaft of the first servo motor 47 is connected to the end of the first rotating shaft 45 away from the drilling tool 46 via a first transmission member 48. When the first servo motor 47 is operated, the first rotating shaft 45 can be driven to rotate under the transmission action of the first transmission member 48.

[0037] In this embodiment, the cutting assembly includes a fifth cylinder 49 mounted on the lifting frame 41. The fifth cylinder 49 is arranged laterally with its telescopic rod facing the loading frame 22. A second fixing member 410 is provided at the end of the telescopic rod of the fifth cylinder 49. The second fixing member 410 is provided with a sampling tube 411 whose length direction is parallel to the axis of the first rotating shaft 45 and is located directly below the first rotating shaft 45. A second rotating shaft 412 with its axis parallel to the axis of the first rotating shaft 45 is rotatably arranged inside the sampling tube 411. A spiral cutter 413 for cutting part of the beet root pieces is mounted at one end of the second rotating shaft 412 near the loading frame 22. The spiral cutter 413 is placed inside the end of the sampling tube 411 near the loading frame 22.

[0038] The sampling tube 411 has a cutting edge at its end near the loading frame 22. After part of the beetroot block's outer skin is removed, the lifting frame 41 is controlled to move upward, aligning the spiral cutter 413 with the removed outer skin of the beetroot block. Then, the fifth cylinder 49 is activated, extending the telescopic rod towards the beetroot block, thus bringing the sampling tube 411, the second rotating shaft 412, and the spiral cutter 413 closer to the beetroot block. As the cutting edge of the sampling tube 411 is inserted into the beetroot block, the second rotating shaft 412 is controlled to rotate, thereby driving the spiral cutter 413 to rotate. During the rotation, the extension rod of the fifth cylinder 49... The retracting rod continues to extend to cut a portion of the beetroot chunks into the sampling tube 411, completing the sampling of the beetroot chunks. Subsequently, the telescopic rod of the fifth cylinder 49 retracts, carrying the sample away from the beetroot chunks. At the same time, the sampling tube 411 passes directly above the sample placement mechanism 3. When the end of the sampling tube 411 with the cutting edge is positioned directly above the sample placement mechanism 3, the spiral cutter 413 is driven to rotate in the opposite direction. Because the spiral cutter 413 is spirally designed, the sample in the sampling tube 411 will be pushed out by the spiral cutter 413 and fall onto the sample placement mechanism 3, where it will cooperate with the juicing mechanism 5 for juicing.

[0039] To control the rotation of the second rotating shaft 412, a second servo motor 414 is mounted on the second fixing member 410. The output shaft of the second servo motor 414 is connected to the end of the second rotating shaft 412 away from the spiral cutter 413 via a second transmission component 415. When the second servo motor 414 is operated, the second rotating shaft 412 can be driven to rotate under the transmission action of the second transmission component 415.

[0040] The first transmission component 48 and the second transmission component 415 are both existing technologies and can be composed of a transmission wheel and a transmission belt, or two meshing gears, which will not be described in detail here.

[0041] like Figure 7 As shown, the sample placement mechanism 3 includes a support block 31 and a sample placement tray 32 mounted on the support block 31. The sample placement tray 32 is placed directly below the juice pressing mechanism 5 and is used to place the sample with juice. The edge of the sample placement tray 32 is formed with a drainage groove 33 to guide the juice to the detection mechanism 6. The spiral cutter 413 rotates in the opposite direction to push the sample out and drop it into the sample placement tray 32. Then, the juice pressing mechanism 5 is run to press and juice the sample in the sample placement tray 32. The juice is guided to the detection mechanism 6 through the drainage groove 33. The detection mechanism 6 is run to detect the sugar content of the juice.

[0042] After the test is completed, residue remains in the sample tray 32. To clean the residue, the sample placement mechanism 3 also includes a swing arm 35 and a third servo motor 34 mounted on the support frame 1. One end of the swing arm 35 is fixed to the support block 31, and the other end of the swing arm 35 is fixed to the output shaft of the third servo motor 34. A left support platform 36 for supporting the support block 31 is provided below the juicing mechanism 5, and a right support platform 37 for supporting the swinging support block 31 is provided on the support frame 1. When the sample tray 32 is placed directly below the juicing mechanism 5, the support block 31 is supported by the left support platform 36, so that the sample tray 32 can fully withstand the pressure applied by the juicing mechanism 5. After juicing is completed, the third servo motor 34 is run, thereby driving the swing arm 35 to rotate around its output shaft, causing the support block 31 and the sample tray 32 to swing clockwise around its output shaft (the swing direction is...). Figure 7 Based on this, the swing angle is preferably 90°. When the support block 31 swings to be supported by the right support platform 37, the residue in the sampling tray 32 automatically falls out. Furthermore, by controlling the support block 31 and the sampling tray 32 to swing back and forth, and cooperating with the right support platform 37, the residue attached to the inner wall of the sampling tray 32 can be vibrated off. In addition, when the support block 31 is supported by the right support platform 37, the sampling tray 32 is positioned directly above the cleaning mechanism 7. After the residue falls out, the cleaning mechanism 7 is activated to rinse the inner wall of the sampling tray 32.

[0043] In this embodiment, the juicing mechanism 5 includes a first linear drive module 51 mounted vertically on the support frame 1. A sixth cylinder 52 with a downward-facing telescopic rod is mounted on the movable end of the first linear drive module 51. A second mounting member 53 is mounted on the end of the telescopic rod of the sixth cylinder 52, and a juicing block 54 for pressing and juicing the sample in the sample tray 32 is provided on the second mounting member 53. Operating the sixth cylinder 52 controls the downward movement of the juicing block 54, thus pressing and juicing the sample in the sample tray 32. Furthermore, by operating the first linear drive module 51, the sixth cylinder 52 and the juicing block 54 move up and down. When the movement reaches its highest point, it makes way for the support block 31 and the sample tray 32, which need to swing; when the movement reaches its lowest point, it facilitates juicing.

[0044] In this embodiment, the detection mechanism 6 includes a seventh cylinder 61 mounted on the support frame 1. The seventh cylinder 61 is arranged laterally, and a mounting frame 62 is mounted on the end of its telescopic rod. The mounting frame 62 is equipped with a sugar content detection device 63 for detecting the sugar content of the juice. The telescopic rod of the seventh cylinder 61 is aligned with the loading frame 22. Before juicing, the seventh cylinder 61 is operated, and the telescopic rod extends to move the sugar content detection device 63 directly below the diversion channel 33. The diversion channel 33 guides the juice onto the sugar content detection device 63. After the detection is completed, the telescopic rod of the seventh cylinder 61 retracts to reset the sugar content detection device 63. After resetting, it is placed in the cleaning position of the cleaning mechanism 7. While cleaning the sample tray 32, the sugar content detection device 63 can also be cleaned. The sugar content detection device 63 is existing technology and can be a hammer mill, etc., which will not be described in detail here.

[0045] like Figure 7-8 As shown, the cleaning mechanism 7 includes a water storage tank 74 and a fixed base 71 installed on the support frame 1. The fixed base 71 is equipped with a high-pressure water pump 72. The water inlet end of the high-pressure water pump 72 is connected to a water inlet pipe 73 connected to the water storage tank 74. The water outlet end of the high-pressure water pump 72 is connected to a water outlet pipe 75. The water outlet end of the water outlet pipe 75 is equipped with a three-way pipe 76. One end of the three-way pipe 76 is connected to a detection equipment rinsing pipe 77 for rinsing the sugar content detection equipment 63. The other end of the three-way pipe 76 is connected to a tray rinsing pipe 78. The end of the tray rinsing pipe 78 is connected to a rinsing section for rinsing the bottom surface and side walls of the flipped sample tray 32.

[0046] When the telescopic rod of the seventh cylinder 61 is in the retracted state, the spray end of the flushing pipe 77 of the testing equipment is aligned with the sugar content testing equipment 63. When the third servo motor 34 controls the support block 31 and the sample tray 32 to swing clockwise around its output shaft until they are supported by the right support platform 37, the flipped sample tray 32 is aligned with the flushing section and placed directly above it. Then the high-pressure water pump 72 is run, and the flushing pipe 77 of the testing equipment sprays water to clean the sugar content testing equipment 63. At the same time, the tray flushing pipe 78 transports water and flushes the bottom and side walls of the sample tray 32 through the flushing section. After the continuous flushing is completed, the third servo motor 34 controls the support block 31 and the sample tray 32 to reset.

[0047] The rinsing section includes a second linear drive module 79 mounted on the support frame 1 and arranged vertically. A lifting seat 710 is mounted on the movable end of the second linear drive module 79. A fourth servo motor 711 with its output shaft facing upward is mounted on the lifting seat 710. A vertically arranged rotating tube 712 is fixedly mounted on the end of the output shaft of the fourth servo motor 711. The rotating tube 712 is coaxial with the output shaft. A plurality of connecting tubes 714 are arranged equidistantly around the output shaft of the fourth servo motor 711 and are connected to the periphery of the rotating tube 712. The length direction of the connecting tubes 714 is perpendicular to the length direction of the rotating tube 712. The rinsing section also includes an annular tube 713 whose center point coincides with the center point of the rotating tube 712 and is connected to the plurality of connecting tubes 714. A plurality of water spray holes are provided at the top of each connecting tube 714. A plurality of water spray holes are provided at the top and sides of the annular tube 713. The tray rinsing tube 78 is connected to the rotating tube 712 through a hose 715.

[0048] After being flipped, the sampling tray 32 is placed directly above the annular tube 713. First, the second linear drive module 79 is activated, controlling the fourth servo motor 711, the rotating tube 712, the annular tube 713, and several connecting tubes 714 to move upward together. After the annular tube 713 and several connecting tubes 714 are placed inside the sampling tray 32, the high-pressure water pump 72 is activated. The tray flushing pipe 78 and the hose 715 deliver water to the rotating tube 712, then to the annular tube 713 and several connecting tubes 714, and finally spray it out from several spray holes. This can simultaneously flush the bottom and side walls of the sampling tray 32, improving the flushing efficiency of the sampling tray 32. In addition, while flushing, the fourth servo motor 711 is activated, which can control the annular tube 713 and several connecting tubes 714 to rotate in both directions (the angle of rotation does not exceed 180°), so that the several spray holes can fully flush the sampling tray 32, further improving the flushing efficiency.

[0049] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.
