[0036] Combination Figures 1 to 3 As shown, the utility model provides a soil sampling device, including a shell 100 and a ring drill 200. The shell 100 is surrounded by a sampling space 110. The shell 100 is provided with a first opening 120 and an observation port 130. The first opening 120 and the observation port 130 are located at two ends of the shell 100; the ring drill 200 is coaxially connected to the first opening 120, and the drill bit 210 of the ring drill 200 faces away from the sampling space 110.
[0037] When collecting soil samples, the soil sampling device of the embodiment of the utility model places the annular drill 200 against the soil surface, and the user presses and rotates the outer shell 100. The drill bit 210 of the annular drill 200 cuts the soil and drives the outer shell 100 to gradually sink. The cut soil enters the sampling space 110 of the outer shell 100. When the user checks through the observation port 130 to see if the soil sample fills the sampling space 110, the user pulls out the soil sampling device to obtain the soil sample that fills the sampling space 110.
[0038] The soil sampling device of the embodiment of the utility model is provided with an observation port 130. During the soil sampling process, the user can visually check whether the soil sample fills the entire sampling space 110 without having to rely on feeling (such as feeling that the soil sampling device cannot be pressed down further, and continuing to press down will cause additional pressure on the outer shell 100 and the annular drill 200), thereby effectively protecting the outer shell 100 and the annular drill 200; and the overall structure of the device is simple and reliable, which is easy to carry.
[0039] In this embodiment, the observation port 130 is an opening corresponding in size to the first opening 120 . In other embodiments, the observation port 130 may not be corresponding in size to the first opening 120 , that is, the observation port 130 may be disposed on the wall surface of the housing 100 opposite to the first opening 120 .
[0040] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the soil sampling device also includes a sampling bag 300, which is arranged in the sampling space 110; the soil sample is cut by the auger 200 and enters the sampling bag 300, and the sampling bag 300 ensures that the soil sample will not adhere to the inner surface of the housing 100, reducing the cleaning cost of the soil sampling device; and different sampling bags 300 are used for different soil samples, effectively avoiding contamination between different soil samples. The auger 200 is detachably connected to the housing 100; ensuring that the auger 200 can be replaced separately, reducing maintenance costs.
[0041] In one embodiment, the opening limit of the sampling bag 300 is located between the auger 200 and the housing 100 , ensuring that the soil sample completely enters the sampling bag 300 without leaking out from the outside of the opening of the sampling bag 300 to pollute the sampling space 110 .
[0042] In one embodiment, the sampling bag 300 is limited between the auger 200 and the housing 100, and the opening is located outside the sampling space 110. At this time, the edge of the opening of the sampling bag 300 is located outside the housing 100 (the inside is the sampling space 110), which is conducive to the user's intuitive understanding that the edge of the opening of the sampling bag 300 completely exceeds the connection between the auger 200 and the housing 100, ensuring that the sampling bag 300 is completely fixed and no soil sample will leak out during the sampling process.
[0043] According to an embodiment provided by the utility model, combined with Figure 1 As shown, the housing 100 is provided with a first threaded portion 140, and the annular drill 200 is provided with a second threaded portion 220 that matches the first threaded portion 140, and the threaded connection method is simple and reliable.
[0044] The first threaded portion 140 and the second threaded portion 220 limit the sampling bag 300. During the screwing process of the first threaded portion 140 and the second threaded portion 220, the sampling bag 300 fills the gap between the threads, effectively ensuring the stable connection between the auger 200 and the housing 100, and the threaded fit makes the sampling bag 300 completely fixed in the circumferential direction, avoiding the problem of soil sample leakage in some positions of the sampling bag 300 due to the loose fit between the auger 200 and the housing 100.
[0045] In other embodiments, the connection between the ring drill 200 and the housing 100 may also be in the form of a snap-on connection, such as providing a snap-on socket on the ring drill 200 or the housing 100, and providing a buckle on another corresponding snap-on socket, and the buckle and the snap-on socket are snap-connected to fix the two and simultaneously limit the position of the sampling bag 300.
[0046] According to an embodiment provided by the utility model, combined with Figure 1 and Figure 2 As shown, the soil sampling device further includes a handle 400 , a first end 410 of the handle 400 is connected to the housing 100 , and a second end 420 deviates away from the axis of the annular drill 200 ; the handle 400 and the annular drill 200 are respectively located at two ends of the housing 100 .
[0047] When sampling, the user can rotate the housing 100 through the handle 400 to drive the auger 200 to rotate, thereby speeding up the progress of soil sample collection; and the handle 400 deviating from the axis of the auger 200 is conducive to increasing the force arm of the handle 400 in the radial direction of the axis of the auger 200, while the user can also press the handle 400 downward along the axial direction to further speed up the progress of sample collection.
[0048] According to an embodiment provided by the utility model, combined with Figure 3 As shown, the soil sampling device includes at least two handles 400, and the at least two handles 400 are symmetrically distributed around the center of the annular drill 200. This is beneficial for the user to grasp different handles 400 with both hands when using the soil sampling device, thereby ensuring the rotation stability of the soil sampling device.
[0049] In this embodiment, three handles 400 are provided; in other embodiments, the number of handles 400 can be changed according to needs.
[0050] In this embodiment, the handle 400 is provided on the housing 100 and is located at the edge of the observation port 130. It can be understood that when the size of the observation port 130 is reduced, the position of the handle 400 can also be correspondingly close to the rotation axis of the soil sampling device; and when the observation port 130 is not coaxial with the rotation axis of the soil sampling device, the first end 410 of the handle 400 can also be arranged to pass through the rotation axis of the soil sampling device.
[0051] According to an embodiment provided by the utility model, combined with Figure 1 and Figure 2 As shown, the handle 400 is rotatably connected to the housing 100 via the rotating portion 430, and the rotation axis of the handle 400 is perpendicular to the axis of the annular drill 200. When the user needs to perform soil sampling, the handle 400 can be rotated to a certain position (such as perpendicular to the rotation axis of the soil sampling device), thereby increasing the force arm of the soil sampling device during sampling and reducing the user's work intensity. When not in use, the handle 400 can be rotated to a position parallel to the soil sampling device, and does not protrude from the housing 100 in the axial direction along the rotation axis of the soil sampling device, thereby reducing the space required for placement and improving portability.
[0052] In one embodiment, the length of the handle 400 is smaller than the diameter of the observation port 130 . In this case, the handle 400 can be rotated into the sampling space 110 , further reducing the volume required for placing the soil sampling device.
[0053] According to an embodiment provided by the present utility model, the rotating part 430 includes a rotating base 431 and a rotating shaft 432, wherein the rotating base 431 is disposed on one of the housing 100 or the handle 400, and the rotating shaft 432 is disposed on the other;
[0054] In this embodiment, combined with Figure 1 and Figure 2 As shown, taking the rotating base 431 disposed on the housing 100 and the rotating shaft 432 disposed on the handle 400 as an example, a shaft sleeve is disposed on the rotating base 431 at the shaft end corresponding to the rotating shaft 432, and the rotating shaft 432 is inserted into the shaft sleeve to realize the rotating connection.
[0055] In other embodiments, the rotating portion 430 may also be a relatively rotatable structure such as a universal joint, a ball head, and a spherical socket.
[0056] In one embodiment, a limiting portion 433 is provided between the rotating base 431 and the rotating shaft 432, which is suitable for limiting the rotation position of the handle 400 relative to the housing 100. In this embodiment, the limiting portion 433 is a limiting surface on the rotating base 431 that can abut against the side wall of the handle 400. When the handle 400 is rotated to be perpendicular to the rotation axis of the soil sampling device, it abuts against the limiting surface and cannot continue to rotate. When the soil sampling device is working, by providing the limiting portion 433, even if the user does not hold the handle 400, the handle 400 can be kept at a position perpendicular to the rotation axis of the soil sampling device, which is beneficial for the user to directly rotate the handle 400 without adjusting the position of the handle 400.
[0057] In other embodiments, the limiting portion 433 may also be a protrusion disposed on the rotating shaft 432 , and during the rotation of the protrusion, the protrusion will abut against the rotating base 431 to limit the handle 400 .
[0058] According to an embodiment provided by the utility model, an extension rod is sleeved on the second end 420 of the handle 400. When the observation window is too small, the handle 400 that can be rotated into the sampling space 110 can be correspondingly reduced, resulting in a too short lever arm. The extension rod can lengthen the lever arm of the soil sampling device on the basis of the handle 400, effectively reducing the user's work intensity.
[0059] According to an embodiment provided by the utility model, the volume of the sampling space 110 is 480 to 520 cubic centimeters. When the soil sample fills the sampling space 110, it is just full to the observation port 130. The volume of the soil sample obtained by the user each time the sampling bag 300 is the same; and the weight of a common soil sample corresponding to 480 to 520 cubic centimeters is 0.9 to 1.1 kilograms, which ensures that the mass of the soil sample obtained each time is close, which is conducive to unifying the standard of soil samples.
[0060] According to an embodiment provided by the utility model, the shell 100 is cylindrical, which is conducive to the rotation and sinking of the soil sampling device. The length of the shell 100 is 9 to 11 centimeters and the diameter is 3 to 5 centimeters. The overall shape is adapted to the user's palm holding shape, thereby improving the convenience of the soil sampling device.
[0061] Of course, in other embodiments, the size of the sampling space 110 and the size of the housing 100 may be adjusted according to the volume and mass required for soil sample measurement.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
