Description

Technical Field

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

[0002] Soil sampling and extraction equipment is a professional tool used to collect and extract soil samples;

[0003] There are many different soil sampling and extraction tools available;

[0004] The most common sampling tools are of the following types;

[0005] Rotary soil auger: Its drill bit is spiral-shaped; it rotates into the soil to collect soil samples at different depths. It is easy to operate and suitable for various soil textures, but it may be difficult to operate in hard or rocky soils.

[0006] Impact soil auger: uses impact force to drive the drill bit into the soil, suitable for sampling hard soil or deep soil; it usually requires greater force to operate and can be equipped with a mechanical device to improve efficiency.

[0007] However, most of the soil collection tools mentioned above require mechanical devices. For example, a rotary soil drill may require a motor tool, and an impact soil drill may require a pressure device, which makes them somewhat inconvenient to carry. Existing portable sampling devices include Luoyang shovels.

[0008] The Luoyang shovel has the advantages of simple structure, light weight and easy to carry;

[0009] The Luoyang shovel consists of a shovel head and a shovel handle; the shovel head is crescent-shaped, with a blade at one end and the other end connected to the shovel handle; the shovel head is usually made of steel, with a certain curvature and sharp edge, which is convenient for cutting into the soil; the shovel handle is generally made of wood or metal, and the length is determined according to the usage requirements, so that the user can hold and operate it; and when sampling, the sharp blade and curvature of the shovel head are used to insert the Luoyang shovel vertically into the soil by manpower, and then the shovel body is rotated to make the soil gather in the curved space of the shovel head, and then the shovel is lifted out of the ground to take out the soil sample.

[0010] However, the inner wall of the existing Luoyang shovel head is mostly smooth when in use. When collecting and extracting soil, sometimes the friction between the shovel body and the soil is insufficient, making it difficult to extract the soil from the ground. Summary of the Invention

[0011] In view of the problem that the friction between the shovel body and the soil is insufficient, which makes it difficult to extract the soil from the ground, the present invention proposes a deep soil sampling and extraction device, which includes a shovel body and a shovel handle provided at the upper end of the shovel body; the shovel body also includes:

[0012] The shovel body is in the shape of a ring with a notch on one side;

[0013] An opening and closing groove is provided on the side of the shovel body; a rotation groove is provided at the center of the upper end of the opening and closing groove;

[0014] The opening and closing plate is arranged inside the opening and closing groove, and a protrusion is provided at the center position of the upper end of the opening and closing plate, and the protrusion is rotatably connected in the rotating groove; an arc-shaped block inclined downward is provided on the outer side of the lower end of the opening and closing plate;

[0015] The arc-shaped plate is arranged at the middle part of the inner side of the lower end of the opening and closing plate, and the curvature of the arc-shaped plate coincides with the rotation track of the lower end of the opening and closing plate.

[0016] As a preferred solution of the present application, in the initial state, one end of the arc-shaped plate away from the clamping plate is located on the central axis inside the shovel body.

[0017] As a preferred solution of the present application, an arc-shaped groove is opened inside the shovel body, one end of the arc-shaped groove is connected to the side wall of the opening and closing groove, and the other end is connected to the inner side of the shovel body; an elastic plate is slidably connected inside the arc-shaped groove, the elastic plate is an arc-shaped structure, and one end of the elastic plate is connected to the side of the opening and closing plate, and the other end of the elastic plate is located in the middle of the shovel body.

[0018] As a preferred solution of the present application, the elastic plate is made of elastic metal sheet.

[0019] As a preferred solution of the present application, a plurality of strip grooves are evenly formed on the elastic plate, and the plurality of strip grooves make the elastic plate a rake-like structure.

[0020] As a preferred solution 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.

[0021] As a preferred solution of the present application, a limiting member is provided at one end of the arc-shaped plate away from the clamping plate, and the limiting member is used to limit the position of the arc-shaped plate.

[0022] As a preferred solution of the present application, the limiting member is a rod, and the upper end of the limiting member is hinged to the lower end of the arc plate, and the rotation angle of the limiting member is between 50° and 90°.

[0023] The beneficial effects are as follows;

[0024] The side of the opening and closing plate cuts the soil, so that the soil at the upper end of the arc plate and the soil at the lower end of the arc plate inside the shovel body are separated. After separation, the opening and closing plate is rotated to a position that does not overlap with the initial state. Then 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 toward the inside of the opening and closing groove until the opening and closing plate closes the opening and closing groove. During the process, the arc plate is embedded into the inside of the shovel body, so that the arc plate is embedded in the soil inside the shovel body; during the upward extraction of the shovel body, the soil is cut by the arc plate, making the soil easier to lift, and in the process of lifting, the arc plate supports the lower end of the cut soil, which is more convenient for lifting the soil.

[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:

[0034] like Figures 1 to 6 As shown; A deep soil sampling and extraction device, the sampling and extraction device includes a shovel body 1 and a shovel handle 2 arranged at the upper end of the shovel body 1; the shovel body 1 also includes:

[0035] The shovel body 1 is in the shape of a ring with a notch on one side;

[0036] An opening and closing groove 11 is provided on the side of the shovel body 1; a rotation groove 12 is provided at the center of the upper end of the opening and closing groove 11;

[0037] The opening and closing plate 13 is arranged inside the opening and closing groove 11, and a protrusion is provided at the center of the upper end of the opening and closing plate 13, and the protrusion is rotatably connected to the rotating groove 12; the outer side of the lower end of the opening and closing plate 13 is provided with an arc-shaped block 14 inclined downward;

[0038] The arc-shaped plate 15 is arranged at the middle portion of the inner side of the lower end of the opening and closing plate 13, and the curvature of the arc-shaped plate 15 coincides with the rotation trajectory of the lower end of the opening and closing plate 13;

[0039] In the initial state, one end of the arc-shaped plate 15 away from the clamping plate 13 is located on the central axis inside the shovel body 1 .

[0040] Here’s how it works:

[0041] 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 inserted vertically into the ground, the edge of the lower end of the shovel body 1 is 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 plate 15 arranged on the outside of the shovel body 1 will come into contact with the ground. Then the staff continues to squeeze the shovel body 1 downward. During the process, since the arc block 14 is located on the outside of the lower end of the opening and closing plate 13 and the arc block 14 is tilted downward, the soil will squeeze the arc block 14. After the inner side of the arc block 14 is squeezed, the arc The arc block 14 is subjected to the resistance of the soil, and the arc block 14 will move in the direction away from the outside of the shovel body 1. During this process, the arc block 14 will drive the opening and closing plate 13 to rotate, and the protrusion at the upper end of the opening and closing plate 13 will rotate inside the rotating groove 12, so that the lower end of the opening and closing plate 13 will move in the direction away from the closing groove 11. During this process, the opening and closing plate 13 drives the arc plate 15 to move toward the outside of the shovel body 1. Since the curvature of the arc plate 15 coincides with the trajectory generated when the opening and closing plate 13 rotates with the protrusion as the center, the arc plate 15 will be driven to rotate when the opening and closing plate 13 rotates, and the arc plate 15 will not be stuck with the lower wall of the opening and closing groove 11.

[0042] After the opening and closing plate 13 is opened, 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 interior 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 curved plate 15 to rotate. Since the curved plate 15 is initially located on the central axis of the shovel body 1, the curved plate 15 performs a circular cutting on the soil at this position during its rotation. At the same time, the side of the opening and closing plate 13 cuts the soil, so that the soil at the upper end of the curved plate 15 inside the shovel body 1 is cut into the soil at the position where the shovel body 1 is located. The soil at the lower end of the curved plate 15 is separated. After separation, the opening and closing plate 13 is rotated to a position that does not overlap with the initial state. Then 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, causing the opening and closing plate 13 to rotate 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 the process, the curved plate 15 is embedded into the inside of the shovel body 1, so that the curved plate 15 is embedded 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 curved plate 15, making it easier to lift the soil, and during the lifting process, the curved plate 15 supports the lower end of the cut soil, making it easier to lift the soil.

[0043] And in the process of the shovel body 1 moving upward, after the opening and closing plate 13 is closed, since the arc block 14 on the outer side of the lower end of the opening and closing plate 13 is set to be inclined downward, when the arc block 14 moves upward, the soil will continue to exert force on the outer side of the arc block 14, squeezing the arc block 14 toward the position of the opening and closing groove 11, so that the opening and closing plate 13 will not move out from the inside of the opening and closing groove 11, thereby improving the discharge effect.

[0044] Example 2:

[0045] like Figures 2 to 6 As shown; an arc-shaped groove 16 is provided inside the shovel body 1, one end of the arc-shaped groove 16 is connected to the side wall of the opening and closing groove 11, and the other end is connected to the inner side of the shovel body 1; the interior of the arc-shaped groove 16 is slidably connected to an elastic plate 17, the elastic plate 17 is an arc-shaped structure, and one end of the elastic plate 17 is connected to the side of the opening and closing plate 13;

[0046] The elastic plate 17 is made of elastic metal sheet;

[0047] The elastic plate 17 is evenly provided with a plurality of strip grooves 18 , which give the elastic plate 17 a rake-like structure.

[0048] 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 .

[0049] Here’s how it works:

[0050] An arc-shaped groove 16 is provided inside the shovel body 1, so that one end of the arc-shaped groove 16 is connected to the opening and closing groove 11, and the other end is connected to the inner side of the shovel body 1, and an elastic plate 17 is slidably connected to the inside of the arc-shaped groove 16, and one end of the elastic plate 17 is connected to the opening and closing plate 13. In the above embodiment, during the opening and closing of the opening and closing plate 13, the opening and closing plate 13 drives 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 from 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 with the opening and closing plate 13, the groove wall of the arc-shaped groove 16 will not hinder the elastic plate 17;

[0051] 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 from the inside of the arc groove 16, the soil will block the part of the elastic plate 17 extending from the arc groove 16 during the rotation, so that the part of the elastic plate 17 extending from the arc groove 16 is subjected to pressure from the soil. After the elastic plate 17 is subjected to pressure, the elastic plate 17 moves toward the inside of the arc plate 15, and in the process, the opening and closing plate 13 is driven to reset; then the staff rotates the shovel body 1 and evenly opens a plurality of strip grooves 18 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 extraction process of the shovel body 1, the elastic plate 17 is inserted into the soil, thereby increasing the friction of the shovel body 1 on the soil, thereby facilitating the removal of soil samples.

[0052] Example 3:

[0053] like Figures 1 to 6 As shown; a limit member 19 is provided at one end of the arc-shaped plate 15 away from the plywood 13, and the limit member 19 is used to limit the position of the arc-shaped plate 15;

[0054] The limiting member 19 is a rod, and the upper end of the limiting member 19 is hinged to the lower end of the arc-shaped plate 15. The rotation angle of the limiting member 19 is between 50° and 90°.

[0055] Here’s how it works:

[0056] A limiter 19 is provided at one end of the curved plate 15 away from the closing plate 13. On the basis of the above-mentioned embodiment 1, when the opening and closing plate 13 is opened, the curved plate 15 drives the limiter 19 to move toward the inner wall of the shovel body 1, so that the limiter 19 is a rod. In the initial state, an angle is formed between the limiter 19 and the curved plate 15, so that the angle is between 50° and 90°, so that when the limiter 19 moves with the curved plate 15, the limiter 19 can support the inner wall of the shovel body 1 on the lower side of the opening and closing groove 11, thereby preventing the curved plate 15 from moving out of the opening and closing groove 11;

[0057] When the opening and closing plate 13 closes the opening and closing groove 11, the arc plate 15 moves toward the middle of the shovel body 1. During the process, the arc plate 15 is embedded in the soil sample inside the shovel body 1. The soil sample will block the limiter 19, causing the limiter 19 to rotate. The angle between the limiter 19 and the arc plate 15 becomes smaller and tends to 0°, so that the limiter 19 does not increase the resistance of the arc plate 15 when it is embedded in the soil.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
