Description

Technical Field

[0001] The present invention relates to the field of soil collection, and in particular to a soil information collection device and a collection method for land resource management. Background Art

[0002] Soil sample collection, referred to as sampling, refers to the process of taking a representative part of the soil from the field, field, culture or cultivation unit. The sampled soil sample is prepared into an analytical sample after appropriate treatment. Finally, the test sample taken for analysis is only a few grams or even a few tenths of a gram, and the analysis result should represent the entire soil. Therefore, a representative average sample must be taken correctly, otherwise even if the analysis process is accurate, it will be useless, and may even lead to wrong conclusions, causing unnecessary losses to production or scientific research. Sampling is generally divided into single-point samples and mixed samples. Single-point samples mean that only one point is sampled for each sample, which can be divided into disturbed samples, undisturbed samples and profile samples.

[0003] When sampling soil at different depths, the upper soil can easily enter the sampler as the sampler moves downward, causing the sampled soil to mix with soil at other depths, which reduces the accuracy of soil collection. Moreover, when sampling soil samples at the same depth, the soil at the same position is usually only collected once. If the currently collected soil contains more impurities locally, the soil sampling will not be representative, which will affect subsequent soil analysis.

[0004] Therefore, based on the above problems, we invented a soil information collection device and method for land resource management. Summary of the invention

[0016] Compared with the prior art, the present invention provides a soil information collection device and collection method for land resource management, which has the following beneficial effects: 1. This soil information collection device for land resource management is provided with a driving mechanism. When the collection column is placed in the collection position, the horizontal plate is fixed to the ground by a fixed plug plate, and then the two U-shaped handles are pulled back and forth. The U-shaped handle drives the adjusting gear to rotate under the action of the limit card plate, and the adjusting gear drives the collection column to rise and fall through the tooth groove. The collection column is raised and lowered to a suitable depth in the soil according to the scale, which is relatively simple when installing the soil collection equipment.

[0017] 2. The soil information collection device for land resource management is provided with a collection mechanism. When the collection column is inserted into the soil at a suitable depth, the soil begins to be collected. First, the collection slot is opened, and the second motor drives the four lifting screws to rotate, and the four lifting screws drive the four threaded blocks to lift and lower, and the four threaded blocks drive the shielding plate to lift and lower until the appropriate height, and then the collection slot can be opened. Then, the soil is collected through the collection slot, and the third motor drives the power gear to rotate, and the power gear drives the annular plate to rotate. Since the annular plate is slidably sleeved outside the collection column, when the annular plate rotates, it will drive the collection column to rotate synchronously. During the rotation process, since the collection column will have an extrusion force on the soil when it is inserted into the soil, there is no obstruction at the opening of the collection slot at this time, and part of the soil will be squeezed into the collection slot due to the pressure release. When the collection slot rotates, that is, This part of the soil can be cut off and collected into the collection groove, and then the shielding plate is moved down to protect the collected soil, and the soil at the current depth can be collected. Since the soil at the same collection point is collected at the same time through four collection grooves, after the collection is completed, the soil at four places is compared to remove the soil with too large difference in impurity content, so the soil collection accuracy is high and representative. Finally, the collected soil is taken out and the collection column is moved out to the outside. At this time, the four threaded sleeves are driven to rotate by the first motor, and the four threaded sleeves drive the four threaded rods to move, and the four threaded rods drive the four push plates to move. The push plates can push the soil in the collection groove out, which is more convenient for soil sampling. Moreover, during sampling, due to the protection of the shielding plate, soil at other depths will not enter the collection groove, and the soil sampling accuracy is higher.

[0018] 3. This soil information collection method for land resource management is equipped with a humidity sensor. When selecting soil collection points, the humidity sensor is used to detect the current humidity of the soil. When multiple points are detected, it is ensured that the humidity of the selected sampling points is equivalent, and the humidity of the collected soil is equivalent, thereby improving the soil collection effect.

[0019] The soil collection device of the present invention is easy to install, has high soil collection accuracy and is representative, and can detect the soil moisture at the collection point, thereby improving the soil collection effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a soil information collection device and collection method for land resource management.

[0024] like Figure 1-7 As shown, a soil information collection device for land resource management includes: A horizontal plate 1 is provided with a through hole, in which a collecting column 2 is arranged. It should be noted that a scale 39 is engraved on the side wall of the collecting column 2, a humidity sensor 40 is embedded at the lower end of the horizontal plate 1, and a driving mechanism 3 for driving the collecting column 2 is provided on the horizontal plate 1. It should be noted that the driving mechanism 3 includes an annular plate 15 slidably sleeved on the outside of the collecting column 2, the annular plate 15 is rotatably mounted on the horizontal plate 1, and two adjusting gears 18 are provided above the annular plate 15. The adjusting gear 18 is rotatably mounted with the annular plate 15 through a fixing plate 19, and a tooth groove 20 meshing with the adjusting gear 18 is provided on the collecting column 2, and a U-shaped handle 21 is rotatably mounted outside the adjusting gear 18.

[0025] Through the above-mentioned technical features, before collecting soil, the current humidity of the soil can be detected by the humidity sensor 40. When detecting at multiple points, it is ensured that the humidity of the selected sampling points is equivalent, and the humidity of the collected soil is ensured to be equivalent, thereby improving the collection effect of the soil. It should be noted that when detecting humidity, on the one hand, the soil humidity of multiple collection points is detected to ensure that the humidity is equivalent, and on the other hand, it is ensured that the soil humidity is sufficient to avoid insufficient soil humidity, thereby facilitating soil collection.

[0026] In the present invention, a limit card plate 22 is rotatably installed on the inner wall of the U-shaped handle 21, and the limit card plate 22 matches the adjusting gear 18. An anti-skid plate 23 is provided on the outer cover of the collection column 2, and the anti-skid plate 23 is fixedly connected to the annular plate 15 through two connecting plates 24. Limiting grooves 25 are provided on both ends of the anti-skid plate 23, and a limit plate 26 is rotatably connected in the limiting groove 25. It should be noted that the limit card plate 22 is rotatably connected to the U-shaped handle 21 through a volute spring, and the angle between the limit card plate 22 and the vertical plane is 0-90°. The limit card plate 22 plays the role of a ratchet. When the U-shaped handle 21 rotates downward, it will not drive the adjusting gear 18 to rotate. When the U-shaped handle 21 rotates upward, it can drive the adjusting gear 18 to rotate. The gear 18 rotates, and the limit plate 26 is rotatably connected to the limit groove 25 through a scroll spring. The angle between the limit plate 26 and the vertical plane is 45-90°. The limit plate 26 limits the adjusting gear 18 to prevent the collection column 2 from floating up due to the pressure of the soil during the downward pressing process. The limit plate 26 matches the adjusting gear 18, and the upper sliding connection of the anti-skid plate 23 is provided with two slide plates 27. It is worth mentioning that the friction between the slide plate 27 and the anti-skid plate 23 is greater than the thrust of the limit plate 26 on the slide plate 27, ensuring that the slide plate 27 effectively limits the slide plate 27. The two slide plates 27 are matched with the two limit plates 26 respectively, and the four corners of the lower end of the horizontal plate 1 are fixedly connected with fixed plug plates 4.

[0027] Through the above technical features, before collecting soil, the collecting column 2 needs to be placed in the collecting position. At this time, the horizontal plate 1 is fixed to the ground by the fixed plug plate 4. Since the horizontal plate 1 is associated with the collecting column 2, the collecting column 2 is placed in the collecting position. When the collecting column 2 is placed at a suitable depth in the soil, the two U-shaped handles 21 are pulled back and forth. The U-shaped handles 21 drive the adjusting gear 18 to rotate under the action of the limiting card plate 22. Because the adjusting gear 18 is meshed with the tooth groove 20, the adjusting gear 18 drives the collecting column 2 to rise and fall through the tooth groove 20. Then, the collecting column 2 is lifted and lowered to a suitable depth in the soil according to the scale 39, and the collecting column 2 can be placed at a suitable depth in the soil at the collecting point.

[0028] After the collection column 2 is set, the soil can be collected, so a collection mechanism 5 is set for collecting soil. The collection mechanism 5 includes four collection slots 6 arranged on the side of the collection column 2. A push plate 7 is sealed and slidably installed in the collection slot 6. It should be noted that a cleaning nozzle is provided on the push plate 7, and the cleaning nozzle is connected with the external water supply pipe through the collection column 2. After the soil sampling is completed, the collection slot 6 can be self-cleaned by the cleaning nozzle. A threaded rod 8 is fixedly installed on one side of the four push plates 7. A cavity 9 is provided in the collection column 2. One end of the four threaded rods 8 away from the push plate 7 is slidably penetrated through the collection column 2. The threaded sleeve 10 is provided on the external thread sleeve of the threaded rod 8. One end of the threaded sleeve 10 rotates to penetrate the collection column 2 and extends to the cavity 9. A first motor 11 is installed in the cavity 9. The drive shaft of the first motor 11 is connected to the four The threaded sleeves 10 are connected through a gear set 12. It should be noted that the gear set 12 includes a toothed disc 28 and four driving gears 29. The four driving gears 29 are coaxially fixedly connected to the four threaded sleeves 10 respectively. The toothed disc 28 is coaxially fixedly connected to the driving shaft of the first motor 11. The four driving gears 29 are all meshed with the toothed disc 28. The openings of the four collecting slots 6 are slidably connected with a baffle plate 13. It should be noted that the upper end of the baffle plate 13 is connected with a corrugated plate 38, and the upper end of the corrugated plate 38 is connected to the inner wall of the lifting slot 30. The edges of the corrugated plate 38 are slidably connected to the inner wall of the lifting slot 30. It should be noted that a third motor 16 is installed on the upper end of the cross plate 1, and the driving shaft of the third motor 16 is coaxially fixedly connected with a power gear 17. The side wall of the annular plate 15 is provided with an annular tooth groove meshing with the power gear 17.

[0029] Through the above technical features, the soil is collected through the collecting groove 6, and the power gear 17 is driven to rotate by the third motor 16, and the power gear 17 drives the annular plate 15 to rotate. Since the annular plate 15 is slidably sleeved outside the collecting column 2, when the annular plate 15 rotates, it will drive the collecting column 2 to rotate synchronously. During the rotation process, since the collecting column 2 has an extrusion force on the soil when it is inserted into the soil, there is no obstruction at the opening of the collecting groove 6 at this time, and part of the soil will be squeezed into the collecting groove 6 due to the pressure release. When the collecting groove 6 rotates, this part of the soil can be cut off and collected into the collecting groove 6, and the soil can be collected.

[0030] It is worth mentioning that the collection column 2 is provided with a lifting mechanism 14 for lifting the four shielding plates 13. It should be noted that the lifting mechanism 14 includes four lifting slots 30 arranged on the side wall of the collection column 2, and the four lifting slots 30 are respectively located above the four collection slots 6. The four lifting slots 30 are rotatably connected with lifting screws 31, and the four lifting screws 31 are threadedly sleeved with thread blocks 32 on the outside. The four thread blocks 32 are respectively fixedly connected to the four shielding plates 13. The peripheral side of the collection column 2 is provided with an annular groove 33. The four lifting screws 31 are rotatably connected to the four shielding plates 13. The upper ends of the lowering screws 31 extend into the annular grooves 33 and are connected through a transmission mechanism 34. It is worth mentioning that the transmission mechanism 34 includes four transmission gears 36, which are coaxially fixedly connected to the four lifting screws 31 respectively. A transmission ring 37 is sealed and rotatably installed in the annular groove 33, and an annular tooth groove meshing with the four transmission gears 36 is provided on the inner side wall of the transmission ring 37. A second motor 35 is embedded in the collection column 2, and the drive shaft of the second motor 35 is coaxially fixedly connected to one of the lifting screws 31.

[0031] Through the above technical features, before collecting soil, since the opening of the collection slot 6 is protected by the baffle plate 13, during collection, it is necessary to lift the baffle plate 13 to open the collection slot 6, and drive one of the lifting screws 31 to rotate through the second motor 35, and one of the lifting threaded rods 31 drives the other three lifting screws 31 to rotate under the transmission action of the transmission gear 36 and the transmission ring 37, and the four lifting screws 31 drive the four threaded blocks 32 to lift, and since the threaded blocks 32 are fixedly connected to the baffle plate 13, the four threaded blocks 32 drive the four baffle plates 13 to lift until When the collecting groove 6 is at a suitable height, the collecting groove 6 can be opened; after collecting the soil, the shielding plate 13 is moved down to protect the collected soil. At this time, the collecting column 2 is moved out of the soil, and then the shielding plate 13 is moved up. At this time, the first motor 11 drives the four driving gears 29 to rotate through the toothed disc 28, and the four driving gears 29 drive the four threaded sleeves 10 to rotate. Because the four threaded sleeves 10 are all threaded with threaded rods 8, the threaded sleeves 10 drive the threaded rods 8 to move, and the threaded rods 8 drive the push plate 7 to move, thereby taking out the soil in the collecting groove 6.

[0032] like Figure 8 As shown, a soil information collection method for land resource management includes the following steps: S1. Site survey: collect on-site data, understand on-site conditions such as soil type and plant coverage, and prepare sampling tools; S2. Set sampling points: arrange sampling points and set sampling depth by random sampling, systematic sampling or stratified sampling; S3. Soil collection: insert the horizontal plate 1 at the collection point, shake the U-shaped handle 21, the U-shaped handle 21 drives the collection column 2 to descend through the limit card plate 22, and descend to a suitable depth according to the scale 39, open the shielding plate 13, drive the annular plate 15 to rotate through the third motor 16, and the annular plate 15 drives the collection column 2 to rotate. At this time, the collection slot 6 can collect soil. After the collection is completed, close the shielding plate 13 and lift the collection column 2. Take out the collected soil through the push plate 7, bag it and mark it; S4. Record information: record the location information of the sampling point, sampling time, soil color, climate conditions and other related information for subsequent analysis; S5. Sample processing: remove impurities from the collected soil samples, separate the samples, and store them according to the analysis requirements.

[0033] It should be noted that in step S3, after the horizontal board 1 is inserted at the collection point, the humidity of the currently collected soil is detected by the humidity sensor 40, and when multiple points are detected, it is ensured that the soil humidity is equivalent.

[0034] Working principle: 1) Detect the current humidity of the soil through the humidity sensor 40 to ensure that the humidity of the selected sampling points is equivalent; 2) Then the collection column 2 is placed in the collection position. At this time, the horizontal plate 1 is fixed on the ground by the fixing plug plate 4. Since the horizontal plate 1 is associated with the collection column 2, the collection column 2 is placed in the collection position. When the collection column 2 is placed at a suitable depth in the soil, the two U-shaped handles 21 are pulled back and forth. The U-shaped handles 21 drive the adjusting gear 18 to rotate under the action of the limit card plate 22. Since the adjusting gear 18 is meshed and connected with the tooth groove 20, the adjusting gear 18 drives the collection column 2 to rise and fall through the tooth groove 20. Then, the collection column 2 is lifted and lowered to a suitable depth in the soil according to the scale 39, and the collection column 2 can be placed at a suitable depth in the soil at the collection point. 3) At this time, the shielding plate 13 is raised and lowered, and one of the lifting screws 31 is driven to rotate by the second motor 35. One of the lifting screws 31 drives the other three lifting screws 31 to rotate under the transmission action of the transmission gear 36 and the transmission ring 37. The four lifting screws 31 drive the four threaded blocks 32 to rise and fall. Since the threaded blocks 32 are fixedly connected to the shielding plate 13, the four threaded blocks 32 drive the four shielding plates 13 to rise and fall until they reach a suitable height, and the collection slot 6 can be opened; 4) Then the soil is collected through the collection slot 6, and the power gear 17 is driven to rotate by the third motor 16, and the power gear 17 drives the annular plate 15 to rotate. Since the annular plate 15 is slidably sleeved outside the collection column 2, when the annular plate 15 rotates, it will drive the collection column 2 to rotate synchronously. During the rotation process, since the collection column 2 is inserted into the soil, it will exert a squeezing force on the soil. At this time, there is no obstruction at the opening of the collection slot 6, and part of the soil will be squeezed into the collection slot 6 due to the pressure release. When the collection slot 6 rotates, this part of the soil can be cut off and collected into the collection slot 6; 5) After collecting the soil, the shielding plate 13 is moved downward so that the shielding plate 13 protects the collected soil. At this time, the collecting column 2 is moved out of the soil; 6) Move the shielding plate 13 upward, and the first motor 11 drives the four driving gears 29 to rotate through the toothed disc 28, and the four driving gears 29 drive the four threaded sleeves 10 to rotate. Because the four threaded sleeves 10 are all threaded with threaded rods 8, the threaded sleeves 10 drive the threaded rods 8 to move, and the threaded rods 8 drive the push plate 7 to move, so as to take out the soil in the collection groove 6.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
