Description

Technical Field

[0001] The present invention relates to the technical field of agricultural meteorology, and in particular to a soil collection device for agricultural meteorology. Background Art

[0002] In today's agricultural meteorological research field, soil is the foundation of crop growth, and its various characteristics play a key role in the growth and development of crops, yield quality, and the interaction with the meteorological environment. Loam, in particular, has become the focus of agricultural meteorological research because of its moderate proportion of sand, silt and clay content, and its certain viscosity, air permeability and water retention.

[0003] Although some existing soil sampling devices have improved the efficiency and accuracy of sampling to a certain extent, they still cannot fully meet the diverse needs of agricultural meteorological research. On the one hand, for the stratified sampling of loam at different depths, many devices have difficulty in implementing stratified operations and cannot obtain complete information on loam at different layers. On the other hand, when collecting loam samples, only one form of loam can be obtained, such as a complete columnar form or a loose form. In agricultural meteorological research, it is sometimes necessary to simultaneously compare and analyze the in-situ mechanical properties of loam (such as compressive strength and water retention, which are closely related to the complete structure of the soil) and the natural loose state properties (such as particle grading and solute migration rate). Existing devices cannot meet the need for simultaneous collection of these two types of samples.

[0004] Chinese patent publication number CN221840766U discloses a soil collection device for agricultural meteorology, comprising a second sleeve, a handle, a collection tube, a fixed head, and a sliding block. The upper portion of the second sleeve is rotatably connected to a handle for assisting in pushing and pulling. A semi-circular tubular collection tube is slidably connected to the interior of the second sleeve. A fixed head is sleeved between the upper portions of the two collection tubes, and the fixed head is detachably connected to the second sleeve. The second sleeve is slidably connected to the sliding block. The handle is guided by a bracket, a guide rod, and a fixed seat, allowing a worker to push the second sleeve vertically downward so that the second sleeve and collection tube are vertically inserted into the soil, preventing the second sleeve and collection tube from deflecting during insertion and enabling the collection tube to collect soil from deeper depths.

[0005] However, during use, the above-mentioned device can only sample one form of soil separately, which cannot meet the need of collecting two types of samples at the same time when comparing and analyzing the in-situ mechanical properties and natural loose state properties of the soil, and cannot collect soil at different depths.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1, as Figure 1-2 As shown, a soil collection device for agricultural meteorology includes a fixing device 1, a collection component 2 is provided in the middle position of the fixing device 1, the collection component 2 includes a collection tube 23, a sliding groove 11 is provided at the front end of the fixing device 1, a collection hole 12 is provided at the lower end of the fixing device 1, a bulldozer component 3 is provided on the upper side of the collection component 2, a layered collection component 4 is provided on the lower side of the collection component 2, a cleaning component 5 is provided on the left side of the collection component 2, and a knocking component 6 is provided on the lower side of the cleaning component 5.

[0034] Therefore, through the cooperation of various components, this solution can collect the complete and loose forms of the surface, middle and deep layers of soil when the columnar soil is taken out after collection, meeting the need to collect two types of samples at the same time when comparing and analyzing the in-situ mechanical properties and natural loose state properties of the soil. After the soil collection is completed, the collection tube 23 can also be flushed and knocked to clean it synchronously, avoiding the contamination and interference of these residual substances on the next sampling sample, ensuring the purity of the soil sample collected each time, and improving the overall work efficiency.

[0035] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effect of synchronously collecting the complete form and loose form of soil surface, middle and deep layers.

[0036] See Figure 2 The collection component 2 also includes a hydraulic device 21 fixedly installed on the bottom wall of the inner surface of the sliding groove 11. The output end of the hydraulic device 21 is fixedly connected to a connecting block 22. The inner surface of the front end of the connecting block 22 is fixedly connected to the collection tube 23, and the outer surface of the connecting block 22 is slidably connected to the sliding groove 11.

[0037] The above-mentioned sampling process is the existing technology. The hydraulic device 21 drives the collection tube 23 to collect columnar soil. The principle is that the hydraulic pump pressurizes the hydraulic oil in the oil tank, and transmits it to the hydraulic cylinder after adjustment by the control valve, pushing the piston to drive the collection tube 23. The collection tube 23 line passes through the through groove 4111 and the collection hole 12, and then the cutting edge of its lower end cuts into the soil, overcomes the friction and inserts. The soil enters the tube to form a columnar sample. After insertion to a predetermined depth, the hydraulic device controls the piston to move in the opposite direction to pull out the collection tube 23. During the whole process, the hydraulic system accurately controls and adjusts parameters such as pressure, flow, and speed through control valves and sensors to ensure smooth sampling.

[0038] See Figure 3 The bulldozer assembly 3 includes a hydraulic device 2 31 fixedly installed on the upper end of the fixing device 1. The output end of the hydraulic device 2 31 is fixedly connected to a pushing block 32. The outer surface of the pushing block 32 is slidably connected to the collection pipe 23. The left side of the upper end of the pushing block 32 is fixedly connected to a U-shaped frame 33. The outer surface of the U-shaped frame 33 is slidably connected to the fixing device 1. The left end of the U-shaped frame 33 is fixedly connected to a rack 34.

[0039] Furthermore, the rack 34 moves up and down along with the push block 32;

[0040] The hydraulic device 2 31 is started to drive the pushing block 32 to move downward, so that the columnar soil collected in the collecting pipe 23 can be pushed out.

[0041] See Figure 3 、 Figure 4 、 Figure 5 and Figure 7The layered collection component 4 includes a fixed base 41 fixedly connected to the left side of the upper end of the fixing device 1, the inner surface of the fixed base 41 is rotatably connected to a rotating shaft 1 42, the rear end of the rotating shaft 1 42 is fixedly connected to a one-way rotating shaft 1 431, the outer surface of the one-way rotating shaft 1 431 is rotatably connected to a gear 1 43, the outer surface of the gear 1 43 is meshed with the rack 34, the front end of the rotating shaft 1 42 is fixedly connected to a belt transmission mechanism 1 44, the inner surface of the belt transmission mechanism 1 44 away from the end of the gear 1 43 is fixedly connected to a rotating shaft 2 45, the outer surface of the rotating shaft 2 45 is rotatably connected to a support block 46, the lower end of the support block 46 is fixedly connected to the upper end of the fixing device 1, the rear end of the rotating shaft 2 45 is fixedly connected to a bevel gear transmission group 47, the end of the bevel gear transmission group 47 away from the rotating shaft 2 45 is fixedly connected to an active dial 48, and the outer surface of the active dial 48 is rotatably connected to a groove wheel 49.

[0042] Furthermore, the one-way rotating shaft 1 431 can only rotate in one direction clockwise, that is, only when the rack 34 is descending, the gear 1 43 will drive the one-way rotating shaft 1 431 and the rotating shaft 1 42 to rotate. When the rack 34 rises, only the gear 1 43 rotates, and the one-way rotating shaft 1 431 remains stationary.

[0043] The belt transmission mechanism 44 is composed of two pulleys and a belt.

[0044] The bevel gear transmission set 47 is composed of two bevel gears meshing with each other.

[0045] Furthermore, a cylindrical pin is provided on the surface of the active dial 48, and the active dial 48 rotates continuously at a uniform speed. When the cylindrical pin does not enter the radial groove on the surface of the groove wheel 49, the concave locking arc on the groove wheel 49 is stuck by the convex locking arc on the active dial 48, and the groove wheel 49 is stationary; when the cylindrical pin enters the radial groove of the groove wheel 49, the locking arc is unlocked, and the cylindrical pin drives the groove wheel 49 to rotate a certain angle; when the cylindrical pin is out of the radial groove, the other concave locking arc of the groove wheel 49 is stuck by the convex locking arc of the dial, and the groove wheel 49 is stationary again, thereby realizing intermittent rotation of the groove wheel 49.

[0046] It should be noted that the attached Figure 5 The state of the active dial 48 and the groove wheel 49 is the initial state. At this time, as long as the active dial 48 starts to rotate, the groove wheel 49 will immediately make an intermittent rotation, so that one of the collection boxes 413 quickly reaches the bottom of the collection tube 23.

[0047] The lower end of the sheave 49 is fixedly connected to the rotating shaft 3 410 , the outer surface of the rotating shaft 3 410 is rotatably connected to the fixing device 1 , and the lower end of the rotating disk 411 is fixedly connected to the rotating disk 411 .

[0048] A through groove 4111 is provided on the outer surface of the rotating disk 411, and a rotating seat 412 is fixedly connected to the lower end of the rotating disk 411. The lower end of the rotating seat 412 is rotatably connected to the fixing device 1. Three collection boxes 413 are threadedly connected to the outer surface of the rotating disk 411, and three scrapers 414 are fixedly connected to the upper end of the rotating disk 411. The three scrapers 414 are adapted to the three collection boxes 413, and the outer surfaces of the three scrapers 414 are fixedly connected to the collection boxes 415.

[0049] The scraper 414 follows the rotating shaft 3 410 and can intermittently scrape away the soil pushed out from the bottom end of the collection tube 23 during the rotation process. Figure 4 It can be seen that the rotating disk 411 only needs to be rotated four times to remove three sections of soil, namely the surface layer, middle layer and deep layer of columnar soil in the collection tube 23;

[0050] The height of the scraper 414 is flush with the height of the nozzle of the collection tube 23 at the initial position restored after collection is completed.

[0051] Among them, due to the continuous downward pressure of the pushing block 32, the loam is in a dynamic flow state. When the scraper 414 scrapes to the rear half of the nozzle of the collection tube 23, the front half of the cross-section loses the support of the scraper 414, and the soil pressure above will push the remaining soil to creep downward. At this time, this part of the soil will creep downward along the tiny gap between the side wall of the scraper 414 and the nozzle of the collection tube 23, forming a local accumulation and overflow. The plastic deformation characteristics of the moist soil will aggravate this phenomenon, causing part of the soil to escape from the constraint range and fall. At this time, this part of the spilled soil can directly fall into the collection box 415 on the rear side of the scraper 414, thereby realizing the collection of the naturally loose state of soil at different depths.

[0052] A disposable sample bag can be placed on the collection box 415 to facilitate subsequent collection of loose loam.

[0053] Furthermore, when the pushing block 32 pushes the soil downward, it will drive the rack 34 on one side to engage with the gear 1 43, thereby driving the one-way rotating shaft 1 431 and the rotating shaft 1 42 to rotate, driving the belt transmission mechanism 1 44, the rotating shaft 2 45, the bevel gear transmission group 47, and the active dial 48 to rotate. When the active dial 48 rotates, it will toggle the groove wheel 49 to rotate intermittently. During the rotation process, the groove wheel 49 will drive one of the collection boxes 413 and the scraper 414 to quickly reach the bottom of the collection tube 23. At this time, the soil is still When the old soil is in the process of being pushed out, when the lever on the active dial 48 once again drives the groove wheel 49 to rotate, the collection box 413 and the scraper 414 are also driven to rotate synchronously. At this time, the scraper 414 can slide over the tube mouth of the collection tube 23, and cut off the pushed-out part of the soil as a whole, so that it falls into the collection box 413. The soil collected by the collection box 413 at this time is located at the lower end of the collection tube 23, which is a complete form of deep soil, which is helpful for analyzing the in-situ mechanical properties of the soil, such as compressive resistance and water retention.

[0054] At the same time, when the scraper 414 scrapes to the rear half of the nozzle of the collection tube 23, the front half of the cross-section loses the support of the scraper 414, and the soil pressure above will push the remaining soil to creep downward. At this time, this part of the soil will creep downward along the tiny gap between the side wall of the scraper 414 and the nozzle of the collection tube 23, forming a local accumulation and overflow, and then fall into the collection box 415 on the rear side of the scraper 414. This is a loose state of deep soil, which is helpful for analyzing the particle gradation and solute migration rate of the soil.

[0055] When the rotating disk 411 continues to rotate, the middle layer soil and the surface layer soil in the collection tube 23 can continue to be collected.

[0056] Therefore, this solution, through the cooperation between the collection component 2, the bulldozer component 3 and the layered collection component 4, synchronously drives the intermittent rotational displacement of the three collection boxes 413 during the process of pushing the soil, thereby completing the collection of the complete and loose forms of the surface, middle and deep soil layers, meeting the need for simultaneously collecting two types of samples when comparing and analyzing the in-situ mechanical properties and natural loose state properties of the soil, saving a lot of manpower, and providing rich and effective samples for promoting the development of agricultural meteorological research and comprehensive and in-depth research on various physical, chemical and mechanical properties of the soil.

[0057] Embodiment 3: This embodiment is based on embodiments 1 and 2, and is for achieving the effect of quickly cleaning the collection tube 23.

[0058] See Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9The cleaning component 5 includes an extrusion plate 51 fixedly connected to the lower end of the U-shaped frame 33, a fixing frame 52 fixedly connected to the lower end of the fixing device 1, a water bag 53 fixedly connected to the top wall of the inner surface of the fixing frame 52, the upper end of the extrusion plate 51 is fixedly connected to the lower end of the water bag 53, the upper end of the water bag 53 is fixedly connected to a water pipe 54, the end of the water pipe 54 away from the water bag 53 is fixedly connected to the pushing block 32, and a plurality of nozzles 55 are arranged in a ring at the lower end of the pushing block 32.

[0059] Furthermore, two one-way valves are provided on the outer surface of the water bag 53, one of which is connected to the water pipe 54. When the squeezing plate 51 moves upward to squeeze the water bag 53, the air pressure inside the water bag 53 increases. At this time, the one-way valve starts to supply water to the water pipe 54, and water cannot enter. The other one-way valve is located at the rear end of the water bag 53 and is connected to the external water pipe. When the squeezing plate 51 moves downward to pull the water bag 53, the air pressure inside the water bag 53 decreases, and the water bag 53 can absorb water from the external water source through the one-way valve without discharging water, thereby replenishing the water volume inside the water bag 53.

[0060] Furthermore, the water pipe 54 is an elastic telescopic tube that can be stretched following the lifting and lowering of the push block 32, and a gradient pore size composite membrane is provided at the nozzle of the nozzle 55, and the gradient pore size is designed as follows:

[0061] Surface coarse filter layer: uses a large-pore 50-100 micron polyester fiber woven mesh to allow water to pass through quickly while blocking most soil particles, especially sand and gravel with a particle size of >100 microns;

[0062] Middle layer fine filter layer: uses hydrophilic polyurethane sponge with a pore size of 10 to 20 microns to further filter fine mud and keep the water flow smooth;

[0063] Support layer: The bottom layer is a stainless steel mesh or a hard plastic skeleton, which provides mechanical strength and prevents the membrane from deforming.

[0064] See Figure 7 、 Figure 8 and Figure 10 The knocking assembly 6 includes a gear 2 60 meshing with the outer surface of the rack 34, the inner surface of the gear 2 60 is rotatably connected to the one-way rotating shaft 2 601, the inner surface of the one-way rotating shaft 2 601 is fixedly connected to the rotating rod 602, the rear end of the rotating rod 602 is fixedly connected to the belt transmission mechanism 2 61, the end of the belt transmission mechanism 2 61 away from the rotating rod 602 is fixedly connected to the rotating shaft 4 63, the left end of the fixing device 1 is fixedly connected to the fixing block 62, and the rear end of the rotating shaft 4 63 is rotatably connected to the fixed block 62.

[0065] The front end of the rotating shaft 4 63 is fixedly connected to the rotating plate 64, and one side of the front end of the rotating plate 64 is fixedly connected to the eccentric block 65. The outer surface of the eccentric block 65 is fixedly connected to the connecting rod 66. The rear end of the connecting rod 66 is rotatably connected to the sliding rod 67. The right end of the sliding rod 67 is fixedly connected to the baffle 610, and the right end of the baffle 610 is fixedly connected to the knocking block 68. The front end of the fixing device 1 is fixedly connected to the limiting seat 69, and the outer surface of the sliding rod 67 is slidably connected to the limiting seat 69. The right end of the limiting seat 69 is fixedly connected to the spring 611, and the end of the spring 611 away from the limiting seat 69 is fixedly connected to the baffle 610.

[0066] Furthermore, the one-way shaft 2 601 can only rotate counterclockwise in one direction, that is, only when the rack 34 is rising, the gear 2 60 will drive the one-way shaft 2 601 and the rotating rod 602 to rotate. When the rack 34 descends, only the gear 2 60 rotates and the one-way shaft 2 601 remains stationary.

[0067] The belt transmission mechanism 2 61 mentioned above is composed of two pulleys and a belt.

[0068] Furthermore, the axis of the eccentric block 65 is not on the same horizontal line as the axis of the rotating plate 64. When the rotating plate 64 rotates, the eccentric block 65 can drive the connecting rod 66 and the sliding rod 67 to move left and right, allowing the knocking block 68 to continuously knock on the collection tube 23, loosening some stubborn soil particles or impurities attached to the inner wall of the collection tube 23, and cooperating with the flushing effect of the nozzle 55 to more thoroughly remove these residual substances.

[0069] The limiting seat 69 can limit the sliding rod 67 so that it can only move left and right, and the spring 611 provides a buffer for the knocking block 68.

[0070] Then, after the pushing block 32 completely pushes out the soil inside the collection tube 23, the soil on the surfaces of the three collection boxes 413 and the collection box 415 is removed, and then the hydraulic device 2 31 is started to control the pushing block 32 to rise. During the rising process, the squeezing plate 51 will squeeze the water bag 53, and the water inside the water bag 53 will be sprayed out from the nozzle 55 through the water pipe 54 to clean the inner wall of the collection tube 23. Synchronously, when the rack 34 is rising, it will engage with the gear 2 60, thereby driving the one-way rotating shaft 2 601 and the rotating rod 602 to rotate, driving the belt transmission mechanism 2 61, the rotating shaft 4 63, the rotating plate 64 and the eccentric block 65 to rotate synchronously, so that the connecting rod 66 drives the sliding rod 67 and the knocking block 68 to reciprocate, knocking the surface of the collection tube 23, loosening some stubborn soil particles or impurities attached to the inner wall of the collection tube 23, ensuring the cleanliness of the inside of the collection tube 23, and avoiding affecting the quality of the soil collected next time.

[0071] Therefore, this solution pushes all the soil out through the pushing block 32, and then uses the cooperation of the pusher component 3, the cleaning component 5 and the knocking component 6 to achieve water spray cleaning and external knocking on the inner wall of the collection tube 23 when the pushing block 32 is retracted, so that some stubborn soil particles or impurities attached to the inner wall of the collection tube 23 are loosened, and with the flushing effect, these residual substances are more thoroughly removed, avoiding the contamination and interference of these residual substances on the next sampling sample, ensuring the purity and accuracy of the soil sample collected each time, thereby improving the reliability of subsequent soil analysis results.

[0072] It should be noted that the specific installation method, circuit connection method and control method of the hydraulic device 1 21 and the hydraulic device 2 31 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
