Description

Technical Field

[0002] Saline soil refers to soil containing high concentrations of soluble salts, especially sodium salts (such as sodium chloride, sodium sulfate, etc.). These salts accumulate in the soil and affect plant growth.

[0003] The research on saline soil mainly analyzes the changes in the physical and chemical properties of saline soil, explores the water migration of saline soil, and provides a basis for improving saline soil. In the process of analyzing saline soil, it is necessary to sample the saline soil through a sampling device. The prior art (Chinese invention patent application with publication number CN116839973A) discloses a saline soil detection sampling device, which can make the soil enter the sampling cylinder according to the original stratification to achieve soil sampling;

[0004] Although the function of soil sampling can be realized, the soil samples obtained by this sampling device cannot meet the conditions for analysis.

Soils, 2021, 53(5): 1057–1063.) points out that before experimental analysis of saline soil, the test soil needs to be air-dried, ground, and sieved.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This solution is provided with an electromagnetic heating ring, a sample loosening component and a sample crushing part. When the soil moves in the insertion rod and between the insertion rod and the protective part, the electromagnetic heating ring makes the insertion rod have a certain amount of heat to achieve soil drying. The loosening component performs preliminary cutting of the soil to break up larger soil clods, which is helpful for subsequent filtration and fine processing. The sample crushing part cuts the soil after preliminary filtration again to decompose the soil into finer particles. Then, multi-stage filtration is used to remove soil impurities and screen soil particles to ensure the purity and applicability of the soil. The soil is ground and screened during the sampling process. The soil sampled by this device can be directly used for analysis and detection, eliminating multiple processing steps.

[0021] (2) This solution is provided with a loosening seat, which realizes soil cutting through the inclined surface of the seat body. During the rotation of the seat body, tooth key three drives gear two and the roller body to rotate, and the soil moving along the inclined surface contacts the flange on the outside of the rotating roller body. Larger particles, lumps or hard impurities in the soil will be cut into smaller pieces by the flange on the roller body, which helps to quickly break up larger particles and make the soil particles more uniform and fine, thereby improving the efficiency of soil fragmentation treatment. The particle structure of the soil becomes looser, which is helpful for the subsequent filtration process.

[0022] (3) The present scheme is provided with a grinding sample assembly. The soil processed by the loose sample assembly and passed through the sieve plate 1 falls into the sieve drum. The motor 4 drives the hollow ring body 2 to rotate and drives the sieve drum to rotate. The sieve drum rotates inside the hollow ring body 2 through the cooperation of the gear 6 and the inner tooth groove. When the grinding balls contact the soil in the sieve drum, the particles in the soil can be further ground through rotation and impact, especially those hard or relatively viscous substances. Grinding balls of different sizes can have different effects on soil particles of different sizes. Large particles of soil may be ground by larger grinding balls, while smaller particles are ground by smaller balls, thereby achieving uniform refinement of the soil, improving the efficiency of soil fragmentation, and shortening the processing time of soil from large pieces to fine particles.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0041] The loose sample assembly 6 includes a hollow seat 61 fixedly connected to the lower end of the hand-held part 1, a hollow ring body 62 rotatably connected to the lower end of the hollow seat 61 and located between the cover body 51 and the insertion rod 3, a motor 63 fixedly connected to the outer surface of one of the cover bodies 51, a gear 64 rotatably connected in one of the cover bodies 51 and connected to the output shaft of the motor 63, a tooth key 1 opened on the outer surface of the hollow ring body 62 and meshing with the gear 64, a loose sample seat 65 fixedly connected to the inner wall of the hollow ring body 62 for scraping the sample discharged from the sample discharge port 31, and a combing part 66 fixedly connected to the lower end of the hollow ring body 62. The loose sample seat 65 includes a seat body 651 fixedly connected to the inner wall of the hollow ring body 62, and a slope 652 opened on one side of the seat body 651. The upper ends of the two cover bodies 51 can be clamped on the lower end of the hollow seat 61.

[0042] The sample crushing part 8 includes an outer ring body 83 rotatably connected to the inner wall of one of the cover bodies 51, an inner ring body 84 sleeved on the outside of the insertion rod 3, a connecting rod 85 fixedly connecting the outer ring body 83 and the inner ring body 84, a plurality of sample crushing blades 86 fixedly connected between the outer ring body 83 and the inner ring body 84, and a tooth key 2 opened on the outer surface of the outer ring body 83, one of the cover bodies 51 The outer surface is fixedly connected to a motor 2 81, and one of the cover bodies 51 is rotatably connected to a gear 3 82 meshing with the tooth key 2, and the output shaft of the motor 2 81 is fixedly connected to the gear 3 82.

[0043] The combing part 66 includes a plurality of extension parts 661 integrally formed at the lower end of the hollow ring body 62, a plurality of columns 663 fixedly connected to the lower ends of the plurality of extension parts 661, movable grooves 664 provided in the plurality of columns 663, a movable column 665 movably inserted in the movable grooves 664, a ball 667 rotatably connected to the lower end of the movable column 665 and in contact with the upper surface of the filter plate 7, a spring 666 located in the movable groove 664 and connected to the movable column 665 and the inner wall of the movable groove 664 at both ends, and a plurality of scrapers 662 fixedly connected to the lower ends of the plurality of extension parts 661, respectively. The two cover bodies 51 are both provided with a debris discharge port 54 for discharging impurities on the filter plate 7, and the outer surfaces of the two cover bodies 51 are both clamped with a debris storage box 52 for collecting impurities.

[0044] By adopting the above technical solution, the insertion rod 3 and the soil drill bit 4 are inserted into the soil, and the driving part 2 is controlled to work. In the prior art, the driving part 2 generally adopts a DC motor or a gasoline engine to drive the soil drill bit 4 to rotate. This driving method belongs to the mature prior art and will not be repeated here. The soil drill bit 4 rotates and transports the soil, and the soil moves upward inside the insertion rod 3. In this process, the energy supply module (using lithium batteries, small inverters, etc. as power sources) supplies power to the electromagnetic heating coil. High-frequency and high-voltage current passes through the coil to generate a high-speed changing alternating magnetic field. When the magnetic lines of force in the magnetic field pass through the magnetic conductive metal When the material (insertion rod 3) is inserted, countless small eddies will be generated in the metal body, causing the metal material to heat up quickly, so that the insertion rod 3 has a heating function. The insertion rod 3 can heat the soil inside the insertion rod 3 and between the insertion rod 3 and the cover body 51, and the soil can be dried during the transportation, movement and crushing of the soil. The heating temperature of the insertion rod 3 can be adjusted to avoid the influence of excessive temperature on the components in the soil. The soil above the insertion rod 3 is discharged from the sample discharge port 31 and enters between the insertion rod 3 and the cover body 51. The motor 63 drives the hollow ring body 62 and the loose sample seat 65 to rotate, and the inclined surface on one side of the loose sample seat 65 is used. The soil discharged from the sample discharge port 31 is cut by the scraper 652, and large pieces of soil are cut into small pieces of soil. The cut soil falls on the filter plate 7. When the hollow ring body 62 rotates, it can also drive the extension part 661 to rotate. The ball 667 and the movable column 665 at the lower end of the extension part 661 can loosen the soil on the filter plate 7, and the filter plate 7 filters out large particles in the soil. When the extension part 661 rotates, it can also drive the scraper 2 662 to rotate. The rotation of the scraper 2 662 can drive the large particles on the filter plate 7 to move, drive the large particles to move, and discharge them from the impurity discharge port 54 into the impurity storage box 52, and pass through the filter. When the soil after plate 1 7 passes through the sample crushing part 8 again, the motor 2 81 works to drive the gear 3 82 to rotate, and the rotation of the gear 3 82 drives the outer ring body 83, the inner ring body 84 and the multiple sample crushing blades 86 to rotate. When the soil passes between the outer ring body 83 and the inner ring body 84, the rotating sample crushing blades 86 can cut the soil and decompose the soil into finer particles. The soil passing through the sample crushing part 8 falls on the filter plate 2 91, is filtered by the filter plate 2 91 and falls into the collecting part 13. The collecting part 13 is rotated and screwed out from the lower end of the cover body 51, and the soil in the collecting part 13 can be directly used for analysis and detection, eliminating multiple processing steps.

[0045] like Figure 4 and Figure 5As shown, an annular groove 67 is provided at the lower end of the hollow seat 61, and a tooth key three is provided on the inner wall of the annular groove 67, and the loose seat 65 also includes a roller body 653 rotatably connected to one side of the seat body 651, a plurality of flanges 655 provided on the outer surface of the roller body 653 and one side of the seat body 651, a gear two 654 fixed to one end of the roller body 653 and inserted into the annular groove 67 and meshing with the tooth key three, a material withdrawal groove 656 provided inside the seat body 651, a plurality of comb teeth 657 fixed to the inner wall of the material withdrawal groove 656, and a plurality of rollers 658 rotatably connected to one end of the plurality of comb teeth 657 respectively.

[0046] By adopting the above technical solution, when the seat body 651 rotates, it can drive the gear 2 654 to rotate in the annular groove 67, and the tooth key 3 in the annular groove 67 drives the gear 2 654 and the roller body 653 to rotate. The flange 655 on the outside of the roller body 653 is used to crush the soil moving along the inclined surface 652. The soil moving along the inclined surface 652 contacts the flange 655 on the outside of the rotating roller body 653. The larger particles, lumps or hard impurities in the soil will be cut into smaller pieces by the flange 655 on the roller body 653, which helps to quickly break up larger particles and make the soil particles more uniform and fine, thereby improving the efficiency of soil crushing treatment. The particle structure of the soil becomes looser, which is helpful for the subsequent filtering process, and the flange 655 on one side of the inclined surface 652 is used to clean the flange 655 on the outside of the roller body 653. The flange 655 on the roller body 653 is just located in the gap between two adjacent flanges 655 on the outside of the roller body 653, so that the soil adhering to the two adjacent flanges 655 on the outside of the roller body 653 can be cleaned; because the soil is continuously discharged from the sample discharge port 31, when the inclined surface 652 is initially cut from the sample discharge port 31, when the next adjacent seat body 651 cannot reach the vicinity of the sample discharge port 31, the soil continuously discharged from the sample discharge port 31 can be guided by multiple comb teeth 657, and the soil is loosened by the comb teeth 657 and large soil blocks are separated into small soil blocks. The roller 658 is designed to reduce resistance to avoid the comb teeth 657 from getting stuck due to excessive resistance during the loosening process. If a jam occurs or the inside of the device needs to be cleaned, the two cover bodies 51 are separated to quickly clean the inside of the device.

[0047] like Figure 3 , Figure 7-Figure 9As shown, a sample grinding assembly 10 is also connected between the filter plate 1 7 and the sample crushing part 8, and the sample grinding assembly 10 includes a hollow ring body 101 rotatably connected to the inner wall of one of the cover bodies 51, a tooth key 4 102 opened on the outside of the hollow ring body 101, a plurality of sieve cylinders 105 rotatably connected inside the hollow ring body 101, a plurality of gears 6 106 rotatably connected in the hollow ring body 101 and respectively fixed to the outside of the plurality of sieve cylinders 105, and a plurality of grinding balls 107 of different sizes located inside the sieve cylinder 105, the inner walls of the two cover bodies 51 are provided with internal tooth grooves 55 meshing with the gear 6 106, a motor 4 103 is fixedly connected to the outer wall of one of the cover bodies 51, and a gear 5 104 meshing with the tooth key 4 102 is rotatably connected in one of the cover bodies 51, and the output shaft of the motor 4 103 is fixedly connected to the gear 5 104.

[0048] A scraper 56 is fixedly connected to the inner wall of one of the cover bodies 51, and the lower end of the scraper 56 contacts the upper surface of the hollow ring body 101. A brush 57 is fixedly connected to the upper end of the scraper 56, and the brush 57 contacts the lower surface of the filter plate 7.

[0049] By adopting the above technical solution, the soil passing through the filter plate 1 7 will first fall on the hollow ring body 2 101 before reaching the sample crushing part 8, and the motor 4 103 will drive the gear 5 104 to rotate, and the gear 6 106 will rotate to drive the hollow ring body 2 101 to rotate. When the hollow ring body 2 101 rotates, the scraper 1 56 can scrape the soil falling on the upper surface of the hollow ring body 2 101 into the screen drum 105, and the rotation of the hollow ring body 2 101 drives the screen drum 105 and the gear 6 106 to rotate. While the gear 6 106 rotates, it also contacts the inner tooth groove 55, and the inner tooth groove 55 drives the gear 6 106 and The sieve drum 105 rotates in the hollow ring body 101. When the grinding balls 107 come into contact with the soil in the sieve drum 105, the particles in the soil, especially those hard or relatively viscous substances, can be further ground through rotation and impact. Grinding balls 107 of different sizes can have different effects on soil particles of different sizes. Large particles of soil may be ground by larger grinding balls 107, while smaller particles are ground by smaller balls, thereby achieving uniform refinement of the soil, improving the efficiency of soil fragmentation processing, and shortening the processing time of soil from large pieces to fine particles.

[0050] like Figure 3 As shown, a connecting frame 11 is fixedly connected to the outer surface of one of the cover bodies 51, and both ends of the connecting frame 11 penetrate the cover body 51 and contact the filter plate 1 7 and the filter plate 2 91 respectively. Two vibration parts 12 are fixedly connected to one side of the connecting frame 11.

[0051] By adopting the above technical solution, the vibration part 12 adopts a vibration motor. The vibration generated by the vibration part 12 is transmitted to the cover body 51, filter plate 1 7 and filter plate 2 91 through the connecting frame 11. The vibration of filter plate 1 7 and filter plate 2 91 can improve the filtering effect on the soil. After the vibration is transmitted to the cover body 51, it can be transmitted to the hollow ring body 2 101, the screen cylinder 105, the grinding ball 107 and the sample crushing blade 86, thereby improving the filtering effect of the screen cylinder 105, the impact effect of the grinding ball 107, and the cutting effect of the sample crushing blade 86.

[0052] like Figure 3 , Figure 7 and Fig.11 As shown, the two cover bodies 51 are each provided with an avoidance groove 58, and a final grinding assembly 9 is connected above the filter plate 2 91, and the final grinding assembly 9 includes a toothed disc 94 rotatably connected to one of the avoidance grooves 58, an extension end integrally formed on the inner wall of the toothed disc 94, a pressure roller 95 rotatably connected to the lower end of the extension end, and a scraper 3 96 fixedly connected to the lower end of the extension end, and a motor 3 92 is fixedly connected to the outer wall of one of the cover bodies 51, and a gear 4 93 meshing with the toothed disc 94 is rotatably connected inside the cover body 51, and the output shaft of the motor 3 92 is fixedly connected to the toothed disc 94.

[0053] The lower end of the scraper plate 3 96 contacts the upper end of the filter plate 2 91 , and the exteriors of the two cover bodies 51 are both clamped with a shell 53 for covering the exteriors of the motor 1 63 , the motor 2 81 , the motor 3 92 , and the motor 4 103 .

[0054] By adopting the above technical solution, when soil falls on the filter plate 2 91, the motor 3 92 can drive the gear 4 93 to rotate, and the rotation of the gear 4 93 drives the toothed disc 94 to rotate, and the rotation of the toothed disc 94 drives the pressure roller 95 and the scraper 3 96 to rotate. The pressure roller 95 first flattens the soil on the filter plate 2 91 to help the soil pass through the filter plate 2 91, and then the scraper 3 96 scrapes up the compacted soil on the filter plate 2 91, and the soil is repeatedly compacted, filtered and scraped loose, thereby improving the efficiency of the soil passing through the filter plate 2 91.

[0055] Method of use: insert the insertion rod 3 and the soil drill bit 4 into the soil, control the driving part 2 to work, the soil drill bit 4 rotates and transports the soil, the soil moves upward inside the insertion rod 3, the insertion rod 3 can heat the soil inside the insertion rod 3 and between the insertion rod 3 and the cover body 51, and the soil is dried during the soil transportation, movement and crushing process. The soil above the insertion rod 3 is discharged from the sample discharge port 31 and enters between the insertion rod 3 and the cover body 51, and the motor 63 works to drive the hollow ring body 62 and the loose sample seat 65 to rotate. The inclined surface 652 on one side of the sample loosening seat 65 cuts the soil discharged from the sample discharge port 31. When the seat body 651 rotates, it can drive the gear 2 654 to rotate in the annular groove 67. The tooth key 3 in the annular groove 67 drives the gear 2 654 and the roller body 653 to rotate. The flange 655 on the outside of the roller body 653 is used to crush the soil moving along the inclined surface 652. The soil moving along the inclined surface 652 contacts the flange 655 on the outside of the rotating roller body 653. Larger particles, lumps or hard impurities in the soil will be crushed by the roller body 653. The flange 655 cuts the soil into smaller pieces, and the soil falls on the filter plate 17. The filter plate 17 filters out the large particles in the soil. The soil after passing through the filter plate 17 falls on the hollow ring body 101. When the hollow ring body 101 rotates, the scraper 156 can scrape the soil falling on the upper surface of the hollow ring body 101 into the screen drum 105. The rotation of the hollow ring body 101 drives the screen drum 105 and the gear 6 106 to rotate. While the gear 6 106 rotates, it also contacts the inner tooth groove 55. The inner tooth groove 55 drives the gear 6 106 and the screen drum 105 to rotate in the hollow ring body. The grinding balls 107 rotate in the sieve cylinder 101, and when they come into contact with the soil in the sieve cylinder 105, the particles in the soil are further ground. When the soil discharged from the sieve cylinder 105 passes between the outer ring body 83 and the inner ring body 84, the rotating crushing blades 86 can cut the soil and decompose the soil into finer particles. The soil passing through the crushing part 8 falls on the filter plate 91, and falls into the collecting part 13 after being filtered by the filter plate 91. The collecting part 13 is rotated and screwed out from the lower end of the cover body 51, and the soil in the collecting part 13 can be directly used for analysis and detection.

[0056] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
