Description

Technical Field

[0001] The present application relates to the technical field of soil sampling, and in particular to a soil sampling device for agronomists. Background Art

[0002] In agricultural production and scientific research, soil sampling is a key link in obtaining soil information, evaluating soil quality, and formulating reasonable farming measures.

[0003] A Chinese patent discloses a soil sampling device for agronomists, with the authorization announcement number CN214952305U. Although the above patent uses the cooperation between the slider, the scale and the bolt, the user inserts the sampling rod into the soil when sampling. At this time, the soil will enter the inside of the sampling rod. The user can observe the soil through the observation window and judge the specific thickness of each layer in the soil through the scale. In addition, the slider limits the sampling rod to ensure the vertical movement of the sampling rod and avoid deviation. This solves the problem that the existing device only observes the stratification of the soil after pushing the soil out of the sampler during operation, which will cause deviations in the results and affect the normal judgment of the technicians, thereby improving the practicality. However, the overall components of the above device are relatively complex, not light and simple enough, and it is not convenient for agronomists to move or carry it when actually using it, which brings about the problem of inconvenience in use and reduces the practicality of the above device to a certain extent. Therefore, a person skilled in the art provides a soil sampling device for agronomists to solve the problems raised in the above background technology. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present application provides a soil sampling device for an agronomist, which solves the problems mentioned in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the present application is implemented through the following technical solutions: a soil sampling device for an agronomist, comprising a connecting rod and a sampling cylinder fixedly connected to the bottom of the connecting rod, two handles are symmetrically fixedly connected to the top of the connecting rod, a sliding sleeve is slidably connected to the outer side of the connecting rod, a pedal is fixedly connected to the outer side of the sliding sleeve, the pedal is connected to the adjacent handle through a first adjustment component, and the first adjustment component is used to adjust the height position of the pedal;

[0008] A movable plate with a conical bottom is slidably connected to the inner wall of the sampling cylinder. The movable plate is connected to the connecting rod via a second adjusting component, and the second adjusting component is used to adjust the position of the movable plate inside the sampling cylinder.

[0009] By adopting the above technical solution, the second adjustment component is operated so that the movable plate is located at the top of the inner wall of the sampling tube. When the sampling tube is inserted into the soil by operating the handle, pressure can be applied to the pedal to facilitate the insertion of the sampling tube into the soil to complete the sampling work. The second adjustment component is operated to adjust the position of the movable plate so that the movable plate moves downward, which can conveniently push the soil out of the sampling tube. When sampling of deeper soil is required, the sampling tube can be blocked by the second adjustment component so that the movable plate is located at the opening of the sampling tube. When the sampling tube is inserted into the pre-sampled soil, the second adjustment component is operated so that the movable plate moves upward to the top of the inner wall of the sampling tube. The sampling tube can be continuously inserted downward to sample soils of different depths, and the position of the pedal can be adjusted by operating the first adjustment component to facilitate the agronomist to apply pressure to the pedal. It is flexible and convenient to use, and the overall structure is simple and lightweight, which is easy to move and carry, and can meet the sampling work of soils of different depths, and is highly practical.

[0010] Preferably, the first adjustment assembly includes an internal threaded plate fixedly connected to the top of the handle and a second screw rod threadedly connected to the inside of the internal threaded plate, and the bottom of the second screw rod passes through the inside of the handle and is rotatably connected to the top of the pedal.

[0011] By adopting the above technical solution, when the second screw rod is rotated, the second screw rod can be moved up and down by the threaded connection between the second screw rod and the internal threaded plate. The second screw rod moving up and down can adjust the height position of the pedal, so as to adjust the pedal upward according to the depth of the sampling tube and the connecting rod inserted into the soil, so that the agronomist can more conveniently increase the pressure through the pedal to insert the sampling tube into the soil for sampling, which is flexible to use.

[0012] Preferably, the second adjustment assembly includes a first screw rod which is threadably connected to the inner part of the connecting rod, and the bottom of the first screw rod passes through the sampling tube and is rotatably connected to the top of the movable plate.

[0013] By adopting the above technical solution, when the first screw rod is rotated, the up and down movement operation of the first screw rod can be realized through the threaded connection between the first screw rod and the connecting rod. When the first screw rod moves upward, it can drive the movable plate to move to the top of the inner wall of the sampling tube, so as to complete the soil sampling work through the sampling tube. When the first screw rod moves downward, it can drive the movable plate to move downward to the opening of the sampling tube, so as to realize the sealing operation of the sampling tube.

[0014] Preferably, the surfaces on the same side of the sampling cylinder and the connecting rod are jointly provided with scale lines, and the bottom of the sampling cylinder is used as the zero scale of the scale lines.

[0015] By adopting the above technical solution, when the sampling tube is inserted into the soil for sampling, the agronomist can observe the position of the ground surface at the scale line, thereby facilitating the agronomist to intuitively understand the sampling depth.

[0016] Preferably, the tops of the first screw rod and the second screw rod are both symmetrically fixedly connected with two rotating handles.

[0017] By adopting the above technical solution, rotating the corresponding rotating handle can drive the corresponding first screw rod or second screw rod to rotate, making the rotation operation of the first screw rod and the second screw rod more convenient.

[0018] Preferably, the outer sides of the two handles are fixedly connected with anti-slip rubber sleeves.

[0019] By adopting the above technical solution, the friction between the agronomist's hand and the handle is increased, so that the agronomist can hold the handle more stably to perform sampling operations.

[0020] Preferably, the bottom of the sampling tube is provided with an oblique edge inclined inwards.

[0021] By adopting the above technical solution, the bottom is provided with an inclined edge of an inclined structure, which can make it easier for the sampling tube to be inserted into the soil.

[0023] The present application provides a soil sampling device for an agronomist. The device has the following beneficial effects:

[0024] 1. The soil sampling device for agronomists adjusts the position of the movable plate inside the sampling tube by setting the second adjustment component. When sampling of deeper soil is required, the sampling tube can be sealed by the movable plate and then inserted to the pre-sampling soil depth to meet the sampling needs of deeper soil. The device is flexible to use and has a simple and lightweight overall structure, which is easy to move and carry.

[0025] 2. The soil sampling device for agronomists adjusts the position of the pedal by setting the first adjustment component, which is convenient for agronomists to increase pressure through the pedal to insert the sampling tube into the soil for sampling, and is easy to use.

[0031] The present application is further described in detail below through drawings and examples.

[0032] Reference Figure 1 and Figure 2 The embodiment of the present application provides a soil sampling device for an agronomist, comprising a connecting rod 1 and a sampling tube 2 fixedly connected to the bottom of the connecting rod 1, two handles 5 symmetrically fixedly connected to the top of the connecting rod 1, and a sleeve 3 slidably connected to the outer side of the connecting rod 1. The outer side of the sleeve 3 is fixedly connected to a pedal 4, and the pedal 4 is connected to the adjacent handle 5 through a first adjustment component. The function of the first adjustment component is to adjust the height position of the pedal 4. A movable plate 6 with a conical bottom structure is slidably connected to the inner wall of the sampling tube 2, and the movable plate 6 is connected to the connecting rod 1 through a second adjustment component. The function of the second adjustment component is to adjust the position of the movable plate 6 in the sampling tube 2; specifically, the second adjustment component is operated so that the movable plate 6 is located at the top of the inner wall of the sampling tube 2, and when the handle 5 is operated to insert the sampling tube 2 into the soil, pressure can be applied to the pedal 4 to facilitate the insertion of the sampling tube 2 into the soil to complete the sampling work. The second adjustment component is operated to adjust the position of the movable plate 6 so that the movable plate 6 moves downward, which can easily push the soil out of the sampling tube 2. When it is necessary to sample deeper soil, the sampling tube 2 can be sealed by positioning the movable plate 6 at the opening of the sampling tube 2 through the second adjusting component. When the sampling tube 2 is inserted into the pre-sampled soil, the second adjusting component is operated to move the movable plate 6 upward to the top of the inner wall of the sampling tube 2. The sampling tube 2 can be continuously inserted downward to sample soil at different depths. The position of the pedal 4 can be adjusted by operating the first adjusting component to facilitate the agronomist to apply pressure to the pedal 4. While being flexible and convenient to use, the overall structure is simple and lightweight, which is convenient to move and carry, and can meet the sampling work of soil at different depths. It is highly practical.

[0033] Reference Figure 1 and Figure 2The first adjustment component includes an internal thread plate 11 fixedly connected to the top of the handle 5 and a second screw rod 10 threadedly connected to the inside of the internal thread plate 11. The bottom of the second screw rod 10 passes through the inside of the handle 5 and is rotatably connected to the top of the pedal 4; specifically, when the second screw rod 10 is rotated, the second screw rod 10 can be moved up and down by the threaded connection between the second screw rod 10 and the internal thread plate 11. The second screw rod 10 that moves up and down can adjust the height position of the pedal 4, so that the pedal 4 can be adjusted upward according to the depth of the sampling tube 2 and the connecting rod 1 inserted into the soil, so that the agronomist can more conveniently increase the pressure through the pedal 4 to insert the sampling tube 2 into the soil for sampling, which is flexible to use.

[0034] Reference Figure 3 and Figure 4 The second adjustment component is composed of a first screw rod 7 connected to the internal thread of the connecting rod 1. The bottom of the first screw rod 7 passes through the sampling tube 2 and is rotatably connected to the top of the movable plate 6. Specifically, when the first screw rod 7 is rotated, the first screw rod 7 can be moved up and down through the threaded connection between the first screw rod 7 and the connecting rod 1. When the first screw rod 7 moves upward, it can drive the movable plate 6 to move to the top of the inner wall of the sampling tube 2, so as to complete the soil sampling work through the sampling tube 2. When the first screw rod 7 moves downward, it can drive the movable plate 6 to move downward to the opening of the sampling tube 2 to realize the blocking operation of the sampling tube 2.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The tops of the first screw rod 7 and the second screw rod 10 are symmetrically fixedly connected with two rotating handles 8. Rotating the corresponding rotating handle 8 can more conveniently drive the corresponding first screw rod 7 or the second screw rod 10 to rotate.

[0036] Reference Figure 1 The surfaces on the same side of the sampling tube 2 and the connecting rod 1 are jointly provided with a scale line 9, with the bottom of the sampling tube 2 being the zero scale. When the sampling tube 2 is inserted into the soil for sampling, the agronomist can observe the position of the ground surface at the scale line 9, thereby facilitating the agronomist to intuitively understand the sampling depth.

[0037] Reference Figure 1 and Figure 2 The outer sides of the two handles 5 are fixedly connected with anti-skid rubber sleeves 12, which can be made of rubber material, to increase the friction between the agronomist's hand and the handle 5, so that the handle 5 can be held more stably for sampling operations.

[0038] Reference Figure 2 and Figure 4 The bottom of the sampling tube 2 is provided with an inwardly inclined bevel 13, and the inclined bevel 13 can make it easier for the sampling tube 2 to be inserted into the soil.

[0039] Working principle:

[0040] The first screw rod 7 is rotated to drive the movable plate 6 to move to the top of the inner wall of the sampling tube 2 through the threaded connection between the first screw rod 7 and the connecting rod 1. When the operating handle 5 inserts the sampling tube 2 into the soil, pressure can be applied to the pedal 4 to facilitate the insertion of the sampling tube 2 into the soil to complete the sampling work; the first screw rod 7 is rotated to drive the movable plate 6 to move downward, so that the soil can be easily pushed out from the inside of the sampling tube 2;

[0041] When it is necessary to sample deeper soil, the first screw rod 7 is rotated to drive the movable plate 6 to move downward to the opening of the sampling tube 2 to achieve the blocking operation of the sampling tube 2. When the sampling tube 2 is inserted into the pre-sampled soil, the first screw rod 7 is rotated to drive the movable plate 6 to move to the top of the inner wall of the sampling tube 2. The sampling tube 2 is continuously inserted downward to sample soil at different depths. The position of the pedal 4 can be adjusted by rotating the second screw rod 10. Under the threaded connection between the second screw rod 10 and the internal threaded plate 11, the height position of the pedal 4 can be adjusted, so that the agronomist can more conveniently increase the pressure through the pedal 4 to insert the sampling tube 2 into the soil for sampling. It is flexible to use and has a simple and lightweight overall structure, which is easy to move and carry. It can meet the sampling work of soil at different depths and has strong practicality.
