Technical Field

[0001] The present invention relates to the technical field of soil sampling, and more specifically, to a deep soil sampling and extraction device. Background Art

[0002] Soil sampling and extraction devices are professional tools for collecting and extracting soil samples; There are various existing soil sampling and extraction tools; The most common sampling tools are as follows; Rotary soil drill: Its drill bit is spiral; by rotating and drilling into the soil, soil samples at different depths can be collected; it is easy to operate and is suitable for various textures of soil, but it may be difficult to operate on hard or rocky soil; Impact soil drill: Using impact force to drive the drill bit into the soil, suitable for sampling hard soil or deep soil; it usually requires a large amount of force to operate and can be paired with mechanical devices to improve efficiency.

[0003] However, most of the above-mentioned soil collection tools require the use of mechanical devices. For example, a rotary soil drill may require an electric tool, and an impact soil drill may require a pressure device, which makes it a bit inconvenient to carry them. And existing portable sampling devices include Luoyang shovels; Luoyang shovels have the advantages of simple structure, being light and easy to carry; A Luoyang shovel consists of a shovel head and a shovel handle; the shovel head is semi-circular, with a cutting edge at one end and connected to the shovel handle at the other end; the shovel head is usually made of steel, with a certain curvature and a sharp edge, which is convenient for cutting into the soil; the shovel handle is generally made of wood or metal, and its length is determined according to the usage requirements for the user to hold and operate; and when sampling, using the sharp cutting edge and curvature of the shovel head, the Luoyang shovel is vertically inserted into the soil by manpower, then the shovel body is rotated to make the soil gather in the arc-shaped space of the shovel head, and then the shovel is lifted out of the ground to bring out the soil sample.

[0004] However, for existing Luoyang shovels, when in use, the inner wall of their shovel heads is mostly smooth. When collecting and extracting soil, sometimes there will be a problem that the friction between the shovel body and the soil is insufficient, resulting in difficulty in lifting the soil out of the ground. Summary of the Invention

[0005] In view of the problem that the friction between the shovel body and the soil is insufficient, resulting in difficulty in lifting the soil out of the ground as mentioned above, the present invention provides a deep soil sampling and extraction device, which includes a shovel body and a shovel handle arranged at the upper end of the shovel body; the shovel body further includes: The shovel body is in a circular ring shape with a notch on one side; An opening and closing groove, which is opened on the side of the shovel body; a rotating groove is opened at the center position of the upper end of the opening and closing groove; The opening and closing plate is arranged inside the opening and closing groove, and a convex block is arranged at the central position of the upper end of the opening and closing plate. The convex block is rotatably connected in the rotating groove; an arc-shaped block inclined downward is arranged on the outer side of the lower end of the opening and closing plate; The arc-shaped plate is arranged in the middle of the inner side of the lower end of the opening and closing plate, and the radian of the arc-shaped plate coincides with the rotation track of the lower end of the opening and closing plate.

[0006] As a preferred scheme of the present application, in the initial state, the end of the arc-shaped plate far away from the opening and closing plate is located on the central axis inside the shovel body.

[0007] As a preferred scheme of the present application, an arc-shaped groove is opened inside the shovel body. One end of the arc-shaped groove is communicated with the side wall of the opening and closing groove, and the other end is communicated with the inner side of the shovel body; an elastic plate is slidably connected inside the arc-shaped groove. The elastic plate is of an arc-shaped structure, and one end of the elastic plate is connected to the side surface of the opening and closing plate, and the other end of the elastic plate is located in the middle of the shovel body.

[0008] As a preferred scheme of the present application, the elastic plate is made of an elastic metal sheet.

[0009] As a preferred scheme of the present application, a plurality of strip-shaped grooves are uniformly opened on the elastic plate, and the plurality of strip-shaped grooves make the elastic plate in a rake-shaped structure.

[0010] As a preferred scheme of the present application, the size of the arc-shaped groove is larger than the size of the elastic plate, and the elastic plate is located in the middle of the arc-shaped groove.

[0011] As a preferred scheme of the present application, a limiting member is arranged at the end of the arc-shaped plate far away from the opening and closing plate, and the limiting member is used for limiting the arc-shaped plate.

[0012] As a preferred scheme of the present application, the limiting member is a rod body, and the upper end of the limiting member is hinged to the lower end of the arc-shaped plate, and the rotation angle of the limiting member is between 50° and 90°.

[0013] The beneficial effects are as follows; The side surface of the opening and closing plate cuts the soil, so that the soil inside the shovel body is separated between the soil above the arc-shaped plate and the soil below the arc-shaped plate. After separation, the opening and closing plate is rotated to a position that does not coincide with the initial state. Subsequently, the staff controls the shovel handle to lift the shovel body upward. During the upward movement of the shovel body, the soil squeezes the upper end of the opening and closing plate, so that the opening and closing plate rotates into the opening and closing groove until the opening and closing plate closes the opening and closing groove. During the process, the arc-shaped plate is embedded into the soil inside the shovel body; so that during the upward extraction of the shovel body; the soil is cut by the arc-shaped plate, making the soil easier to lift, and during the lifting process, the arc-shaped plate supports the lower end of the cut soil, making it more convenient to lift the soil.

[0016] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0017] Embodiment 1:

[0018] As Figures 1 to 6 shown; a deep soil sampling and extraction device, the sampling and extraction device includes a shovel body 1 and a shovel handle 2 provided at the upper end of the shovel body 1; the shovel body 1 further includes: The shovel body 1 is in a circular ring shape with a notch on one side; An opening and closing groove 11, which is opened on the side of the shovel body 1; a rotating groove 12 is opened at the central position of the upper end of the opening and closing groove 11; An opening and closing plate 13, which is arranged inside the opening and closing groove 11, and a convex block is arranged at the central position of the upper end of the opening and closing plate 13, and the convex block is rotatably connected in the rotating groove 12; an inclined downward arc-shaped block 14 is arranged on the outer side of the lower end of the opening and closing plate 13; An arc-shaped plate 15, which is arranged in the middle of the inner side of the lower end of the opening and closing plate 13, and the radian of the arc-shaped plate 15 coincides with the rotation track of the lower end of the opening and closing plate 13; In the initial state, the end of the arc-shaped plate 15 far away from the opening and closing plate 13 is located on the central axis inside the shovel body 1.

[0019] The principle is as follows: When the staff collects soil samples, the staff holds the shovel handle 2 and inserts the shovel body 1 vertically into the ground. When the shovel body 1 is vertically inserted into the ground, first, the edge at the lower end of the shovel body 1 is set to be sharp, so that the lower end of the shovel body 1 will gradually embed into the ground. As the shovel body 1 continues to move downward, the arc-shaped plate 15 arranged outside the shovel body 1 will contact the ground. Subsequently, the staff continues to press the shovel body 1 downward. During this process, since the arc-shaped block 14 is located outside the lower end of the opening and closing plate 13 and the arc-shaped block 14 is arranged obliquely downward, the soil will squeeze the arc-shaped block 14. After the inner side of the arc-shaped block 14 is squeezed, the arc-shaped block 14 is subjected to the resistance of the soil, and the arc-shaped block 14 will move in a direction away from the outside of the shovel body 1. During this process, the arc-shaped block 14 will drive the opening and closing plate 13 to rotate, and the convex block at the upper end of the opening and closing plate 13 rotates inside the rotation groove 12, so that the lower end of the opening and closing plate 13 moves away from the opening and closing groove 11. During this process, the opening and closing plate 13 drives the arc-shaped plate 15 to move toward the outside of the shovel body 1. Since the radian of the arc-shaped plate 15 coincides with the trajectory generated when the opening and closing plate 13 rotates around the convex block as the center, the opening and closing plate 13 drives the arc-shaped plate 15 to rotate when it rotates, and the arc-shaped plate 15 will not get stuck with the lower wall of the opening and closing groove 11; After the opening and closing plate 13 opens, as the shovel body 1 moves downward, the soil will also enter the gap between the opening and closing plate 13 and the opening and closing groove 11. As the shovel body 1 continues to move downward, the soil will enter the inside of the shovel body 1 through the opening and closing groove 11; when the shovel body 1 moves to the depth where sampling is required, the staff rotates the shovel handle 2, so that the shovel handle 2 drives the shovel body 1 to rotate. When the shovel body 1 rotates, it drives the opening and closing plate 13 to rotate, and the opening and closing plate 13 drives the arc-shaped plate 15 to rotate. Since the arc-shaped plate 15 is initially located on the central axis inside the shovel body 1, the arc-shaped plate 15 circularly cuts the soil at this position during the rotation process. At the same time, the side surface of the opening and closing plate 13 cuts the soil, so that the soil inside the shovel body 1 is separated between the soil above the arc-shaped plate 15 and the soil below the arc-shaped plate 15. After separation, the opening and closing plate 13 is rotated to a position that does not coincide with the initial state. Subsequently, the staff controls the shovel handle 2 to lift the shovel body 1 upward. During the upward movement of the shovel body 1, the soil squeezes the upper end of the opening and closing plate 13, so that the opening and closing plate 13 rotates toward the inside of the opening and closing groove 11 until the opening and closing plate 13 closes the opening and closing groove 11. During this process, the arc-shaped plate 15 embeds into the inside of the shovel body 1, so that the arc-shaped plate 15 embeds into the soil inside the shovel body 1; so that during the upward extraction of the shovel body 1; the soil is cut by the arc-shaped plate 15, making it easier to lift the soil. And during the lifting process, the arc-shaped plate 15 supports the lower end of the cut soil, making it more convenient to lift the soil; Moreover, during the upward movement of the shovel body 1, after the opening and closing plate 13 is closed, since the arc-shaped block 14 on the outer side of the lower end of the opening and closing plate 13 is arranged obliquely downward, when the arc-shaped block 14 moves upward, the soil will continuously exert a force on the outer side of the arc-shaped block 14, squeezing the arc-shaped block 14 towards the position of the opening and closing groove 11, so that the opening and closing plate 13 will not move out of the inside of the opening and closing groove 11, improving the discharging effect.

[0020] Embodiment 2:

[0021] As Figures 2 to 6 shown; an arc-shaped groove 16 is formed inside the shovel body 1. One end of the arc-shaped groove 16 communicates with the side wall of the opening and closing groove 11, and the other end communicates with the inner side of the shovel body 1; an elastic plate 17 is slidably connected inside the arc-shaped groove 16. The elastic plate 17 is of an arc-shaped structure, and one end of the elastic plate 17 is connected to the side surface of the opening and closing plate 13; The elastic plate 17 is made of an elastic metal sheet; A plurality of strip-shaped grooves 18 are uniformly formed on the elastic plate 17, and the plurality of strip-shaped grooves 18 make the elastic plate 17 in a rake-like structure; The size of the arc-shaped groove 16 is larger than that of the elastic plate 17, and the elastic plate 17 is located in the middle of the arc-shaped groove 16.

[0022] The principle is as follows: An arc-shaped groove 16 is formed inside the shovel body 1, so that one end of the arc-shaped groove 16 communicates with the opening and closing groove 11, and the other end communicates with the inner side of the shovel body 1. An elastic plate 17 is slidably connected inside the arc-shaped groove 16, and one end of the elastic plate 17 is connected to the opening and closing plate 13. On the basis of the above-mentioned embodiment, during the opening process of the opening and closing plate 13, the opening and closing plate 13 will drive the elastic plate 17 to move outward, so that the end of the elastic plate 17 close to the opening and closing plate 13 extends out of the inside of the arc-shaped groove 16. Since the size of the arc-shaped groove 16 is larger than that of the elastic plate 17, and the elastic plate 17 is located in the middle of the arc-shaped groove 16, when the elastic plate 17 moves along with the opening and closing plate 13, the groove wall of the arc-shaped groove 16 will not obstruct the elastic plate 17; On the basis of the above-mentioned Embodiment 1, when the shovel body 1 moves to the position where sampling is required, the shovel body 1 is controlled to rotate clockwise. Since the end of the elastic plate 17 close to the opening and closing plate 13 extends out of the inside of the arc-shaped groove 16, during the rotation process, the soil will block the extended part of the elastic plate 17, so that the extended part of the elastic plate 17 extending out of the arc-shaped groove 16 is subjected to the pressure of the soil. After the elastic plate 17 is subjected to the pressure, the elastic plate 17 moves towards the inside of the arc-shaped plate 15. During the process, the opening and closing plate 13 is driven to reset; Subsequently, the staff rotates the shovel body 1, and a plurality of strip-shaped grooves 18 are uniformly formed on the elastic plate 17, so that the elastic plate 17 forms a rake-like structure. After the opening and closing plate 13 is reset, the rake-shaped end of the elastic plate 17 is embedded in the soil. Subsequently, during the process of extracting the shovel body 1, the elastic plate 17 is inserted into the soil, increasing the friction between the shovel body 1 and the soil, and thus facilitating the extraction of the soil sample.

[0023] Embodiment 3:

[0024] As Figures 1 to 6 shown; a limiting member 19 is provided at one end of the arc-shaped plate 15 away from the opening and closing plate 13, and the limiting member 19 is used to limit the arc-shaped plate 15; The limiting member 19 is a rod body, and the upper end of the limiting member 19 is hinged to the lower end of the arc-shaped plate 15, and the rotation angle of the limiting member 19 is between 50° and 90°.

[0025] The principle is as follows: A limiting member 19 is provided at one end of the arc-shaped plate 15 away from the opening and closing plate 13. On the basis of the above Embodiment 1, when the opening and closing plate 13 opens, the arc-shaped plate 15 drives the limiting member 19 to move towards the inner wall of the shovel body 1, so that the limiting member 19 is a rod body. In the initial state, there is an included angle between the limiting member 19 and the arc-shaped plate 15, and the included angle is between 50° and 90°. When the limiting member 19 moves with the arc-shaped plate 15, the limiting member 19 can support the inner wall of the shovel body 1 below the opening and closing groove 11 to prevent the arc-shaped plate 15 from moving out of the opening and closing groove 11; When the opening and closing plate 13 closes the opening and closing groove 11, the arc-shaped plate 15 moves towards the middle of the shovel body 1. During the process, the arc-shaped plate 15 is embedded in the soil sample inside the shovel body 1. The soil sample will block the limiting member 19, causing the limiting member 19 to rotate, and the angle between the limiting member 19 and the arc-shaped plate 15 becomes smaller and approaches 0°, so that the limiting member 19 does not increase the resistance when the arc-shaped plate 15 is embedded in the soil.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
