Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil detection system and a detection method for rapid sampling. Background Art

[0002] Soil refers to the loose surface layer of the land surface that is fertile and can grow plants. Its thickness is generally about 2 meters. Soil not only provides mechanical support for plant growth, but also provides the necessary fertility elements such as water, fertilizer, air, heat, etc. for plant growth and development. Soil testing refers to determining the environmental quality (or pollution level) and its changing trend by measuring the representative values ​​of factors affecting soil environmental quality. What we usually call soil testing refers to soil environmental testing.

[0003] Existing sampling equipment generally uses a drill barrel to collect soil columns, and then the soil column needs to be pushed out of the drill barrel. Some relatively moist soil samples are inconvenient to take out, and it is not convenient for staff to directly take out soil samples at different depths in the drill barrel; at the same time, the collected soil samples generally need to go through six processes of drying, picking, grinding, screening, sorting, and bottling before testing, making the overall soil sample testing process more cumbersome, time-consuming and labor-intensive, which not only increases the workload and work difficulty of the staff, but also reduces the efficiency of soil testing.

[0019] The present invention also discloses a rapid sampling soil detection method, which performs sampling detection through a rapid sampling soil detection system, comprising the following steps:

[0020] S1: When taking soil samples in the area to be sampled, place the foot pedal on the ground, and the staff members step on the foot pedal with both feet to fix the support frame;

[0021] S2: Then control the driving motor and the electric heating element in the shaftless spiral conveying blade to work;

[0022] When the driving motor is working, its output shaft drives the input shaft of the gear box to rotate. Through the meshing transmission between the gears inside the gear box, the output speeds of the first output shaft body and the second output shaft body are different.

[0023] When the first output shaft rotates, the driving gear at the bottom thereof meshes with the driven gear on the sleeve for transmission, and the driven gear drives the lifting screw to rotate through the guide bar. When the lifting screw rotates, the sleeve threadedly connected to the lifting screw drives the lifting seat to move downward;

[0024] When the second output shaft body rotates, it drives the shaftless spiral conveying blade to rotate at a high speed, so that when the sampling tube moves downward with the lifting seat and penetrates into the soil, the shaftless spiral conveying blade conveys the soil upward along the sampling tube, and the electric heating element in the shaftless spiral conveying blade heats and dries the moist soil;

[0025] When the driving gear rotates, the driving gear meshes with the gear ring on the top of the storage seat, so that the gear ring drives the storage seat to rotate relative to the lifting seat, so that the storage seat rotates automatically during the sampling process of the sampling tube moving downward;

[0026] S3: The shaftless spiral conveying blades convey the dried soil sample upward and discharge it from the guide pipe. The soil discharged from the guide pipe is sequentially placed in the respective discharge shells of the rotating storage seat, so that the discharge shells arranged circumferentially of the storage seat sequentially store soil at different depths;

[0027] A partition is arranged on one side of the discharge shell close to the upper side plate, so that the mixing chamber stores the mixed soil sample between two adjacent discharge shells, and the soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells;

[0028] S4: The soil sample to be inspected first falls on the upper filter screen. When the storage seat rotates relative to the lifting seat, the upper bevel gear on the first rotating rod meshes with the upper bevel gear ring on the lifting seat, and the lower bevel gear on the second rotating rod meshes with the lower bevel gear ring on the lifting seat;

[0029] When the first rotating rod rotates, the dried and agglomerated soil sample is initially crushed by the crushing rod. There are gravels and grass roots in the crushed soil sample. The gravels avoid the rotation of the crushing rod, and the gravels and grass roots do not hinder the normal rotation and crushing work of the crushing rod.

[0030] After the soil sample is initially crushed by the crushing rod, it will automatically fall down after meeting the mesh drop requirements of the upper filter, and then the soil sample will be placed on the lower filter. The second rotating rod drives the crushing roller to crush the soil sample placed on the lower filter, and the crushed soil sample meets the mesh drop requirements of the lower filter and falls on the guide bottom plate;

[0031] S5: After the sampling is completed, the staff controls the driving motor to reversely drive the output shaft, so that the lifting seat and the storage seat are reset and moved upward, and during this period, the first crushing assembly and the second crushing assembly continue to crush the soil to be inspected;

[0032] After the lifting seat and the storage seat move to the initial position, the staff can directly take out the soil to be inspected and conduct inspection by opening the plug cover at the second discharge port.

[0033] Compared with the prior art, the present invention provides a rapid sampling soil detection system and detection method, which has the following beneficial effects:

[0034] 1. The rapid sampling soil detection system and detection method, when the sampling tube moves downward, the storage seat rotates relative to the lifting seat, so that the soil samples collected by the sampling tube are sequentially placed in each discharge shell of the storage seat, which is convenient for quickly collecting soil samples of different depths during the sampling process, reducing the difficulty of sampling work for staff and improving soil detection efficiency.

[0035] 2. The rapid sampling soil detection system and detection method heats and dries the transported sample through the shaftless spiral conveying blade, and cooperates with the first crushing component and the second crushing component to crush the dry and agglomerated soil. In the soil sampling process, the drying, screening and grinding pretreatment of the soil before detection is realized, which is convenient for the staff to quickly take out the soil sample for detection after the sampling is completed, thereby improving the soil detection efficiency.

[0036] 3. The rapid sampling soil detection system and detection method, by setting the upper filter screen to a concave arc shape, facilitates the soil sample dropped on the upper filter screen to slide to the concave part, so that the first rotating rod drives the crushing rod to continuously crush the soil sample that does not meet the falling requirements of the upper filter screen mesh, and sets the lower filter screen to a straight plate shape, so that the second rotating rod drives the crushing roller to further crush the soil sample, thereby ensuring the crushing effect of the soil sample.

[0037] 4. The rapid sampling soil detection system and detection method, by setting a partition on the side of the discharge shell close to the upper side plate, enables the mixing chamber to store the mixed soil sample between two adjacent discharge shells, and the soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells, thereby avoiding cross contamination during the soil sampling process and improving the accuracy of subsequent soil detection results at different depths.

Two adjacent discharge shells 9 share the same upper side plate 901, and the material guide connecting plate 903 and the material guide bottom plate 904 are both inclined downward.

[0066] Furthermore, partitions 905 are fixedly provided on both sides of the discharge shell 9, and the partitions 905 are placed on the upper side of the lower side plate 902.

[0068] The shaftless spiral conveying blade 6031 conveys the dried soil sample upward and discharges it from the guide pipe 701.

[0072] Specifically, the soil sample to be inspected first falls on the upper filter screen 906. When the storage seat 8 rotates relative to the lifting seat 4, the upper bevel gear 1002 on the first rotating rod 10 is meshed with the upper bevel gear ring 402 on the lifting seat 4 for transmission, and the lower bevel gear 112 on the second rotating rod 11 is meshed with the lower bevel gear ring 403 on the lifting seat 4 for transmission. When the first rotating rod 10 rotates, the crushing rod 1001 is used to preliminarily crush the dried and agglomerated soil sample.

The second rotating rod 11 drives the crushing roller 111 to crush the soil sample placed on the lower filter screen 907. After the crushed soil sample meets the mesh drop requirement of the lower filter screen 907, it falls on the guide bottom plate 904.

After the lifting seat 4 and the storage seat 8 move to the initial position, the staff can directly take out the soil to be inspected and inspect it by opening the plug cover at the second discharge port 804;

[0075] The present application heats and dries the transported sample through the shaftless spiral transport blade 6031, and cooperates with the first crushing component and the second crushing component to crush the dry and agglomerated soil, thereby realizing drying, screening and grinding pretreatment of the soil before testing during the soil sampling process, making it convenient for the staff to quickly take out the soil sample for testing after the sampling is completed, thereby improving the efficiency of soil testing.

[0078] S2: Then control the driving motor 601 and the electric heating element in the shaftless spiral conveying blade 6031 to work;

[0079] When the driving motor 601 is working, its output shaft drives the input shaft of the gear box 6 to rotate. Through the meshing transmission between the internal gears of the gear box 6, the output speeds of the first output shaft 602 and the second output shaft 603 are different.

[0080] When the first output shaft 602 rotates, the driving gear 6021 at the bottom thereof meshes with the driven gear 302 on the sleeve 301 for transmission, and the driven gear 302 drives the lifting screw 3 to rotate through the guide bar 3021. When the lifting screw 3 rotates, the sleeve 301 threadedly connected thereto drives the lifting seat 4 to move downward;

[0081] When the second output shaft 603 rotates, it drives the shaftless spiral conveying blade 6031 to rotate at a high speed, so that when the sampling tube 7 moves downward with the lifting seat 4 and penetrates into the soil, the shaftless spiral conveying blade 6031 conveys the soil upward along the sampling tube 7, and the electric heating element in the shaftless spiral conveying blade 6031 heats and dries the moist soil;

[0082] When the driving gear 6021 rotates, the driving gear 6021 meshes with the gear ring 802 on the top of the storage seat 8, so that the gear ring 802 drives the storage seat 8 to rotate relative to the lifting seat 4, so that the storage seat 8 rotates automatically during the downward movement of the sampling tube 7 for sampling;

[0083] S3: The shaftless spiral conveying blade 6031 conveys the dried soil sample upward and discharges it from the guide pipe 701. The soil discharged from the guide pipe 701 is sequentially placed in each discharge shell 9 of the rotating storage seat 8, so that the discharge shells 9 arranged circumferentially of the storage seat 8 sequentially store soil at different depths;

[0084] A partition plate 905 is provided on one side of the discharge shell 9 close to the upper side plate 901, so that the mixing chamber can store the mixed soil sample between two adjacent discharge shells 9, and the soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells 9;

[0085] S4: The soil sample to be inspected first falls onto the upper filter screen 906. When the storage seat 8 rotates relative to the lifting seat 4, the upper bevel gear 1002 on the first rotating rod 10 meshes with the upper bevel gear ring 402 on the lifting seat 4, and the lower bevel gear 112 on the second rotating rod 11 meshes with the lower bevel gear ring 403 on the lifting seat 4;

[0086] When the first rotating rod 10 rotates, the dried and agglomerated soil sample is initially crushed by the crushing rod 1001. There are gravels and grass roots in the crushed soil sample. The gravels avoid the rotation of the crushing rod 1001, and the gravels and grass roots do not hinder the normal rotation and crushing work of the crushing rod 1001.

[0087] After the soil sample is initially crushed by the crushing rod 1001 and meets the mesh drop requirement of the upper filter screen 906, it will automatically fall down, and then the soil sample will be placed on the lower filter screen 907.

4. A rapid sampling soil detection method, which performs sampling and detection by using a rapid sampling soil detection system as claimed in claim 3, characterized in that: The following steps are involved: S1: When soil sampling is performed in the area to be sampled, the foot pedal (2) is placed on the ground, and the staff members step on the foot pedal (2) with both feet to fix the support frame (1); S2: Then control the driving motor (601) and the electric heating element in the shaftless spiral conveying blade (6031) to operate; When the driving motor (601) is working, its output shaft drives the input shaft of the gear box (6) to rotate, and through the meshing transmission between the internal gears of the gear box (6), the output rotation speeds of the first output shaft body (602) and the second output shaft body (603) are different; When the first output shaft (602) rotates, the driving gear (6021) at the bottom thereof meshes with the driven gear (302) on the sleeve (301) for transmission, and the driven gear (302) drives the lifting screw (3) to rotate via the guide bar (3021), and when the lifting screw (3) rotates, the sleeve (301) threadedly connected thereto drives the lifting seat (4) to move downward; When the second output shaft (603) rotates, it drives the shaftless spiral conveying blade (6031) to rotate at a high speed, so that when the sampling tube (7) moves downward along the lifting seat (4) and penetrates into the soil, the shaftless spiral conveying blade (6031) conveys the soil upward along the sampling tube (7), and the electric heating element in the shaftless spiral conveying blade (6031) heats and dries the moist soil; When the driving gear (6021) rotates, the driving gear (6021) meshes with the gear ring (802) on the top of the storage seat (8) to drive the gear ring (802) to drive the storage seat (8) to rotate relative to the lifting seat (4), so that the storage seat (8) rotates automatically during the sampling process of the sampling tube (7) moving downward; S3: The shaftless spiral conveying blade (6031) conveys the dried soil sample upward and discharges it through the guide pipe (701). The soil discharged from the guide pipe (701) is sequentially placed in the respective discharge shells (9) of the rotating storage seat (8), so that the discharge shells (9) arranged circumferentially on the storage seat (8) sequentially store soil at different depths; A partition plate (905) is arranged on one side of the discharge shell (9) close to the upper side plate (901), so that the mixing chamber can store the mixed soil sample between two adjacent discharge shells (9), and the soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells (9); S4: The soil sample to be tested first falls onto the upper filter screen (906). When the storage seat (8) rotates relative to the lifting seat (4), the upper bevel gear (1002) on the first rotating rod (10) meshes with the upper bevel gear ring (402) on the lifting seat (4) for transmission, and the lower bevel gear (112) on the second rotating rod (11) meshes with the lower bevel gear ring (403) on the lifting seat (4) for transmission; When the first rotating rod (10) rotates, the dried and agglomerated soil sample is initially crushed by the crushing rod (1001). Gravel and grass roots are present in the crushed soil sample. The gravel avoids the rotation of the crushing rod (1001). The gravel and grass roots do not hinder the normal rotation and crushing work of the crushing rod (1001). After the soil sample is initially crushed by the crushing rod (1001), it automatically falls down after meeting the mesh drop requirement of the upper filter screen (906), and then the soil sample is placed on the lower filter screen (907). The second rotating rod (11) drives the crushing roller (111) to crush the soil sample placed on the lower filter screen (907), and the crushed soil sample falls onto the material guide bottom plate (904) after meeting the mesh drop requirement of the lower filter screen (907). S5: After the sampling is completed, the staff controls the driving motor (601) to reversely drive the output shaft, so that the lifting seat (4) and the storage seat (8) are reset and moved upward, and during this period, the first crushing assembly and the second crushing assembly continue to crush the soil to be inspected; After the lifting seat (4) and the storage seat (8) are moved to the initial position, the staff can directly take out the soil to be inspected and conduct inspection by opening the plug cover at the second discharge port (804).
