Description

Technical Field

[0001] The invention relates to the technical field of soil sample sampling, and in particular to an efficient soil sample mixing sampling device and an operating method thereof. Background Art

[0002] Soil sample mixing and sampling is a key link in soil analysis. It ensures that the collected soil samples are representative and uniform, thereby improving the accuracy of the analysis results. When collecting soil samples, the principles of multi-point, random, and equal amount should be followed to ensure that the samples can truly reflect the soil conditions in the sampling area. The selection of sampling points should be based on soil type, topography, vegetation cover, farming management and other factors to ensure that the sampling points are representative. Common sampling methods include diagonal sampling, five-point sampling, serpentine sampling and chessboard sampling, etc. These methods are suitable for plots of different sizes and shapes.

[0003] After searching, the Chinese patent with publication number CN218411954U discloses a soil sample mixing device, including a bottom plate, a plurality of support rods fixedly connected to the upper part of the bottom plate, a top plate fixedly connected to the upper part of the plurality of support rods, a sleeve slidably connected to the outer end of the support rod, a bearing is arranged between the bottom plate and the top plate, a barrel can be inserted into the inner ring of the bearing, the outer ring of the bearing and the sleeve are connected and fixed by a cross bar, springs are abutted on both sides of the sleeve, and the ends of the plurality of springs abut against the bottom plate and the top plate respectively. The present invention is provided with springs and bearings. During the use of the soil sample mixing device, the staff can press down the sleeve by applying force, and then release the sleeve instantly. The sleeve swings up and down under the action of the two groups of springs. At the same time, the barrel is rotatably designed by the cooperation of the bearing and the cross bar. The synchronous barrel swings up and down and rotates irregularly. This is repeated until the soil sample is mixed. Compared with the shaking form of the staff holding the barrel, the burden of the staff can be reduced, making the device more humane; however, the above scheme still has the following shortcomings when it is actually used:

[0004] After the soil sample is mixed using a barrel, in order to conduct more accurate and detailed detection and analysis, such as determining the soil nutrient content, microbial community structure, heavy metal pollution level, etc., it is usually necessary to further subdivide the large amount of mixed samples into several small samples. At present, most laboratories or research institutions still rely on manual division and sampling, which not only requires the staff to have a high degree of professional skills and patience, but also easily leads to inconsistent sampling due to human factors (such as improper operation, judgment errors, etc.), thereby affecting the accuracy and reliability of subsequent analysis results. In addition, the manual division and sampling process is cumbersome and time-consuming, which greatly reduces work efficiency, especially when dealing with a large number of soil samples. This problem is particularly prominent.

[0005] Therefore, the present application provides an efficient soil sample mixing sampling device and an operating method thereof. Summary of the invention

[0045] Preferably, the bottom surface of the discharge pipe fits with the top surface of the turntable, and the diameter of the discharge pipe is the same as the inner diameter of the fixed sleeve.

[0046] Preferably, an efficient soil sample mixing and sampling operation method comprises the following steps:

[0047] Step 1: Add the soil sample and water solvent taken out into the mixing cylinder together, then turn on the servo motor, and the servo motor will first rotate forward. At this time, the vertical side of the driving block is against the side of the fixed block. When the servo motor rotates, it can drive the driving plate and drive the connecting plate and the connecting rod to rotate through the cooperation of the driving block and the fixed block, so that the mixing cylinder can rotate at high speed to perform preliminary mixing on the sample in the mixing cylinder. Then the servo motor can be reversed. In this direction, the inclined surface of the driving block is opposite to the fixed block. Therefore, under the action of the inclined surface, the driving block can reciprocate and lift the fixed block and the connecting plate when rotating with the driving plate, and can be reset with the support spring, so that the mixing cylinder can oscillate in the vertical direction, so that the sample in the mixing cylinder can be fully mixed;

[0048] Step 2: After the sample in the mixing cylinder is mixed, the staff can stop the servo motor. At this time, the discharge pipe at the bottom of the mixing cylinder can be located directly above a through hole on the turntable, and the discharge pipe can fit the turntable. When the control valve is opened, the sample in the mixing cylinder can enter the fixed sleeve and the threaded sleeve under the action of gravity, and the capacity in the threaded sleeve and the fixed sleeve can be adjusted according to the sampling amount. During adjustment, the threaded sleeve can be rotated to make the threaded sleeve slide along the fixed sleeve, so that the capacity inside the fixed sleeve and the threaded sleeve changes, and after the adjustment is completed, the transmission top block at the end of the cover plate can always be located directly below the adjustment ring. After the threaded sleeve is adjusted, the telescopic support rod can be adjusted so that the position of the adjustment ring can correspond to the transmission top block;

[0049] Step 3: When sampling the sample in the mixing cylinder, the sampling container can be placed directly below a threaded sleeve, and then the drive motor can be turned on to drive the turntable to rotate 180° through the connecting shaft. At this time, the positions of the two fixed sleeves are exchanged, and the transmission top block at the end of the cover plate directly above the sampling container can be rotated to the inclined portion of the bottom surface of the adjustment ring. At this time, under the action of the torsion spring, the rotating shaft and the cover plate can be rotated to leak the bottom end of the threaded sleeve, and the internal sample can flow out into the container under the action of gravity. The drive motor can be turned on in sequence to perform multiple quantitative sampling of the sample in the mixing cylinder.

[0050] Beneficial effects of the present invention:

[0051] 1. This efficient soil sample mixing and sampling device, by setting a servo motor and a transmission component, through the precise control of the servo motor, combined with the cooperation between the drive plate, the drive block and the fixed block, the mixing cylinder can perform complex and efficient mixing actions. When the servo motor rotates forward, the mixing cylinder mainly rotates at high speed, which helps the sample to form a strong vortex in the cylinder and initially achieve uniform mixing of the sample. Subsequently, when the servo motor reverses, the inclined surface of the drive block interacts with the fixed block to make the mixing cylinder reciprocate in the vertical direction. It can further break up the tiny aggregates in the sample and ensure that the sample is uniformly mixed in all directions in three-dimensional space. Compared with the traditional single rotation mixing method, this composite motion mode can significantly improve the mixing efficiency and enable the sample to reach an ideal mixing state in a short time.

[0052] 2. This efficient soil sample mixing sampling device, by setting up a material collection component and an adjustable design of a threaded sleeve and a fixed sleeve, can change its position relative to the fixed sleeve by gently rotating the threaded sleeve, thereby adjusting the internal capacity between the two. It not only provides a flexible sampling volume selection range, but also allows fine-tuning according to experimental requirements to ensure the accuracy of sampling. In addition, the adjustment process is simple and quick, without the use of complex tools or equipment, which greatly improves the convenience of sampling.

[0053] 3. This efficient soil sample mixing sampling device is provided with a feeding component. During the sampling process, in order to avoid sample contamination and errors caused by human operation, when the driving motor is started, the turntable will drive the fixed sleeve and the threaded sleeve to rotate to the specified position. At this time, the transmission top block at the end of the cover plate will contact the inclined portion of the bottom surface of the adjusting ring. Under the action of the torsion spring, the rotating shaft and the cover plate will automatically rotate and open to expose the bottom of the threaded sleeve. The sample automatically flows out under the action of gravity and falls into the sampling container below. The entire sampling process does not require human intervention, realizing contactless sampling, which not only improves the hygiene and safety of sampling, but also reduces the influence of human errors on experimental results.

[0066] like Figure 2 , Figure 3 As shown, the transmission assembly includes: a mounting ring 61, which is sleeved on the connecting rod 3, and the mounting ring 61 is rotatably connected to the connecting rod 3; a support spring 62, which is sleeved on the connecting rod 3, and the two ends of the support spring 62 are respectively fixedly connected to the mounting ring 61 and the bracket 2; a connecting disk 63, which is fixedly mounted on the bottom end of the connecting rod 3; a plurality of fixing blocks 64, which are distributed in a circular array and fixedly mounted on the inner side wall of the connecting disk 63; a driving plate 65, which is fixedly mounted on the output end of the servo motor 5, and the top surface of the driving plate 65 is in contact with the bottom surface of the connecting disk 63; a plurality of driving blocks 66, which are distributed in a circular array and fixedly mounted on the side of the driving plate 65 opposite to the connecting disk 63, and one side of the driving block 66 is set as an inclined surface; turn on the servo motor 5, and the servo motor 5 first enters The servo motor 5 then rotates forward, with the vertical side of the driving block 66 abutting against the side of the fixed block 64. When the servo motor 5 rotates, it can drive the driving plate 65 and, through the cooperation of the driving block 66 and the fixed block 64, drive the connecting disk 63 and the connecting rod 3 to rotate, so that the mixing cylinder 4 can rotate at high speed, and the samples in the mixing cylinder 4 can be preliminarily mixed. Then the servo motor 5 can be reversed, and the inclined surface of the driving block 66 in this direction is opposite to the fixed block 64. Therefore, under the action of the inclined surface, the driving block 66 can reciprocatingly lift the fixed block 64 and the connecting disk 63 when rotating with the driving plate 65, and can be reset in cooperation with the supporting spring 62, so that the mixing cylinder 4 can oscillate in the vertical direction, so that the samples in the mixing cylinder 4 can be fully mixed.

[0067] like Figure 1 , Figure 4 , Figure 5 As shown, the material taking assembly includes: a turntable 91, which is rotatably mounted on the inner wall of the connecting frame 8, and the bottom surface of the discharge pipe 11 is in contact with the top surface of the turntable 91; two through ports 92, which are symmetrically opened on the top surface of the turntable 91; two fixed sleeves 93, which are respectively fixedly mounted on the inner walls of the two through ports 92, and the diameter of the discharge pipe 11 is the same as the inner diameter of the fixed sleeve 93; two threaded sleeves 94, which are respectively threadedly mounted on the bottom ends of the two fixed sleeves 93, and a sealing ring is provided between the top end of the threaded sleeve 94 and the fixed sleeve 93; a connecting shaft 95, which is fixedly mounted on the bottom surface of the turntable 91; a driving motor 96, which is fixedly mounted on the bottom end of the fixing frame 7, and the driving motor 9 The output end of 6 passes through the fixed frame 7 and is fixedly connected to the bottom end of the connecting shaft 95; the servo motor 5 is stopped, and at this time the discharge pipe 11 at the bottom of the mixing cylinder 4 can be located just above a through opening 92 on the turntable 91, and the discharge pipe 11 can fit the turntable 91, and when the control valve is opened, the sample in the mixing cylinder 4 can enter the fixed sleeve 93 and the threaded sleeve 94 under the action of gravity, and the capacity of the threaded sleeve 94 and the fixed sleeve 93 can be adjusted according to the sampling amount. When adjusting, the threaded sleeve 94 can be rotated so that the threaded sleeve 94 slides along the fixed sleeve 93, so that the capacity inside the fixed sleeve 93 and the threaded sleeve 94 changes.

[0068] like Figure 1 , Figure 5 , Figure 6As shown, the blanking assembly includes: two mounting brackets 101, which are respectively fixedly mounted on the outer wall of the bottom end of the two threaded sleeves 94; two rotating shafts 102, which are respectively rotatably mounted on the inner wall of the two mounting brackets 101; two torsion springs 103, which are respectively mounted on the ends of the two rotating shafts 102, and the two ends of the torsion springs 103 are respectively fixedly connected to the rotating shaft 102 and the mounting bracket 101; two covering plates 104, which are respectively mounted on the two rotating shafts 102; an adjusting ring 105, which is fixedly mounted on the bottom end of the fixing bracket 7 through a telescopic support rod, and the adjusting ring 105 is coaxially arranged with the turntable 91 and the connecting shaft 95; an inclined portion 106, which is opened on one side of the bottom surface of the adjusting ring 105; two transmission top blocks 107, which are respectively fixedly mounted on one end of the two covering plates 104 away from the threaded sleeve 94, and the transmission top block 107 is located directly below the adjusting ring 105. The transmission top block 107 is made of rubber material, and The top of the transmission top block 107 is set to an arc shape; after the threaded sleeve 94 is adjusted, the telescopic support rod can be adjusted so that the position of the adjusting ring 105 can correspond to the transmission top block 107; when sampling the sample in the mixing cylinder 4, the sampling container can be placed directly below a threaded sleeve 94, and then the driving motor 96 is turned on to drive the turntable 91 to rotate 180° through the connecting shaft 95. At this time, the positions of the two fixed sleeves 93 are exchanged, and the transmission top block 107 at the end of the cover plate 104 located directly above the sampling container can be rotated to the inclined portion 106 on the bottom surface of the adjusting ring 105. At this time, under the action of the torsion spring 103, the rotating shaft 102 and the cover plate 104 can be rotated to leak the bottom end of the threaded sleeve 94, and the internal sample can flow out into the container under the action of gravity. Turning on the driving motor 96 in sequence can perform multiple quantitative sampling of the sample in the mixing cylinder 4.

[0069] The specific working principle of the present invention is as follows:

[0070] When in use, the soil sample and the aqueous solvent taken out can be added into the mixing cylinder 4 together, and then the servo motor 5 can be turned on. The servo motor 5 first rotates forward. At this time, the vertical side of the driving block 66 is against the side of the fixed block 64. When the servo motor 5 rotates, it can drive the driving plate 65 and drive the connecting disk 63 and the connecting rod 3 to rotate through the cooperation of the driving block 66 and the fixed block 64, so that the mixing cylinder 4 can rotate at a high speed to perform preliminary mixing on the sample in the mixing cylinder 4. Then the servo motor 5 can be reversed. In this direction, the inclined surface of the driving block 66 is opposite to the fixed block 64. Therefore, under the action of the inclined surface, the driving block 66 can reciprocate the fixed block 64 and the connecting disk 63 when rotating with the driving plate 65, and can be reset in cooperation with the support spring 62, so that the mixing cylinder 4 can oscillate in the vertical direction, so that the sample in the mixing cylinder 4 can be fully mixed.

[0071] After the sample in the mixing cylinder 4 is mixed, the staff can stop the servo motor 5. At this time, the discharge pipe 11 at the bottom of the mixing cylinder 4 can be located just above a through hole 92 on the turntable 91, and the discharge pipe 11 can fit the turntable 91. When the control valve is opened, the sample in the mixing cylinder 4 can enter the fixed sleeve 93 and the threaded sleeve 94 under the action of gravity, and the capacity in the threaded sleeve 94 and the fixed sleeve 93 can be adjusted according to the sampling amount. During adjustment, the threaded sleeve 94 can be rotated so that the threaded sleeve 94 slides along the fixed sleeve 93, so that the capacity inside the fixed sleeve 93 and the threaded sleeve 94 changes, and after the adjustment is completed, the transmission top block 107 at the end of the cover plate 104 can always be located just below the adjustment ring 105. After the adjustment of the threaded sleeve 94 is completed, the telescopic support rod can be adjusted so that the position of the adjustment ring 105 can correspond to the transmission top block 107.

[0072] When sampling the sample in the mixing cylinder 4, the sampling container can be placed directly below a threaded sleeve 94, and then the drive motor 96 is turned on to drive the turntable 91 to rotate 180° through the connecting shaft 95. At this time, the positions of the two fixed sleeves 93 are exchanged, and the transmission top block 107 at the end of the cover plate 104 located directly above the sampling container can be rotated to the inclined portion 106 on the bottom surface of the adjusting ring 105. At this time, under the action of the torsion spring 103, the rotating shaft 102 and the cover plate 104 can be rotated to leak the bottom end of the threaded sleeve 94, and the internal sample can flow out into the container under the action of gravity. Turning on the drive motor 96 in sequence can perform multiple quantitative sampling of the sample in the mixing cylinder 4, which is more convenient to use.

9. The efficient soil sample mixing sampling device according to claim 8, characterized in that: The bottom surface of the mixing cylinder (4) is provided with a discharge pipe (11), the discharge pipe (11) is connected to the mixing cylinder (4), and a control valve is installed inside the discharge pipe (11). The bottom surface of the discharge pipe (11) is in contact with the top surface of the turntable (91), and the diameter of the discharge pipe (11) is the same as the inner diameter of the fixed sleeve (93).

10. An efficient soil sample mixing and sampling operation method, characterized in that: The following steps are involved: Step 1: Add the soil sample and the aqueous solvent taken out into the mixing cylinder (4), then turn on the servo motor (5), and first rotate forward. At this time, the vertical side of the driving block (66) abuts against the side of the fixed block (64). When the servo motor (5) rotates, it can drive the driving plate (65) and drive the connecting plate 63 and the connecting rod (3) to rotate through the cooperation of the driving block (66) and the fixed block (64), so that the mixing cylinder (4) can rotate at a high speed, and the mixing cylinder (4) can rotate at a high speed. The sample in the cylinder (4) is initially mixed, and then the servo motor (5) can be reversed. In this direction, the inclined surface of the driving block (66) is opposite to the fixed block (64). Therefore, under the action of the inclined surface, the driving block (66) can reciprocate the fixed block (64) and the connecting plate (63) when rotating with the driving plate (65), and can be reset in cooperation with the support spring (62), so that the mixing cylinder (4) can oscillate in the vertical direction, so that the sample in the mixing cylinder (4) can be fully mixed. Step 2: After the sample in the mixing cylinder (4) is mixed, the staff can stop the servo motor (5). At this time, the discharge pipe (11) at the bottom of the mixing cylinder (4) can be located directly above a through opening (92) on the turntable (91), and the discharge pipe (11) can fit the turntable (91). When the control valve is opened, the sample in the mixing cylinder (4) can enter the fixed sleeve (93) and the threaded sleeve (94) under the action of gravity, and the threaded sleeve (94) and the fixed sleeve (93) can be adjusted according to the sampling amount. The capacity of the cover plate (104) can be adjusted. When adjusting, the threaded sleeve (94) can be rotated so that the threaded sleeve (94) slides along the fixed sleeve (93), so that the capacity of the fixed sleeve (93) and the inner side of the threaded sleeve (94) changes. After the adjustment is completed, the transmission top block (107) at the end of the cover plate (104) can always be located directly below the adjustment ring (105). After the threaded sleeve (94) is adjusted, the telescopic support rod can be adjusted so that the position of the adjustment ring (105) can correspond to the transmission top block (107); Step 3: When sampling the sample in the mixing cylinder (4), the sampling container can be placed directly below a threaded sleeve (94), and then the drive motor (96) is turned on to drive the turntable (91) to rotate 180° through the connecting shaft (95). At this time, the positions of the two fixed sleeves (93) are exchanged, and the transmission top block (107) at the end of the cover plate (104) directly above the sampling container can be rotated to the inclined portion (106) on the bottom surface of the adjustment ring (105). At this time, under the action of the torsion spring (103), the rotating shaft (102) and the cover plate (104) can be rotated to leak the bottom end of the threaded sleeve (94), and the sample inside can flow out into the container under the action of gravity. The drive motor (96) is turned on in sequence to perform multiple quantitative sampling of the sample in the mixing cylinder (4).
