Description

Technical Field

[0001] This application relates to the field of soil sampling, and more particularly to a soil sampling device. Background Technology

[0002] Modern archaeological exploration mostly uses the Luoyang shovel. The shovel is manually pressed into the soil layer to extract soil. The extracted soil is then sampled and analyzed to determine the age of the soil and the thickness of the soil layer.

[0003] Typically, the shovel head of a Luoyang shovel can be a straight cylindrical shape with fully enclosed side walls, or a cylindrical structure with open side walls. The inner wall of the cylindrical shovel head is smooth. After the shovel head is inserted into the soil and cuts the soil, in order to bring the soil out of the ground smoothly, the shovel head needs to be shaken to break off the soil at the base of the shovel head. Otherwise, when the shovel head is pulled vertically upwards out of the ground, it is easy to leave soil in the shovel hole and not be able to effectively bring the soil out. A certain skill is required when using a Luoyang shovel to remove soil from the ground.

[0004] Therefore, how to design a soil sampling device that can easily bring soil out of the ground with the shovel head has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This application provides a soil sampling device to at least solve the above-mentioned technical problems existing in the prior art.

[0006] A soil sampling device is provided, including a shovel handle and a shovel head, the shovel head being installed at the end of the shovel handle and having a hollow cylindrical structure;

[0007] The guide is installed in the inner cavity of the shovel head. The guide is inclined and forms an angle with the axis of the shovel head. The distance from the first end of the guide to the axis of the shovel head is greater than the distance from the second end of the guide to the axis of the shovel head.

[0008] The first end is located on the side furthest from the shovel handle compared to the second end.

[0009] In one embodiment, the guide is fixedly installed on the side wall of the inner cavity of the shovel head, the guide is integrally formed with the shovel head, and the longitudinal section of the guide and the shovel head is hook-shaped.

[0010] In one embodiment, the guide includes a guide ramp and an obstructing plane, the obstructing plane being horizontally positioned. The cross-section of the guide is a transverse U-shape, gradually decreasing in cross-sectional area along the shovel handle towards the shovel head.

[0011] In one embodiment, the shovel head and the shovel handle are detachably connected. The shovel head includes a cutting section and a window section, with the window section installed between the cutting section and the shovel handle. It also includes a locking member that fixes the cutting section and the window section to the shovel handle.

[0012] In one embodiment, the window portion has a C-shaped cross-section, and the cutting portion includes a support and a sealing plate fixedly installed on the support and extending along the axis of the cutting head. The sealing plate is inserted into the opening of the window portion, and the sealing plate and the window portion are combined to form a cylindrical shape.

[0013] In one embodiment, the guide is fixedly installed on the inner wall of the support, and the outer wall of the support is provided with a locking groove for the inner recess of the guide.

[0014] In one embodiment, a foot pedal is fixedly provided on the side wall of the shovel bar, extending radially along the shovel bar, and the shovel head is mounted on the foot pedal.

[0015] In one embodiment, a plug-in post is fixedly provided on the foot pedal along the axial direction of the shovel handle, and the top wall of the sealing plate is provided with a plug-in groove along the axial direction of the shovel handle. When the shovel head is installed, the plug-in post is inserted into the plug-in groove.

[0016] In one embodiment, the locking component includes a through hole, a transmission rod, a locking head, a locking plate, and a locking bolt. The through hole is arranged along the axial direction of the shovel head and passes through the window portion. The transmission rod is disposed in the through hole and extends to the bottom of the window portion, where it is connected to the locking head. The locking head is inserted into the locking groove, and the top wall of the locking head abuts against the top wall of the locking groove. The transmission rod extends upward and passes through the foot pedal. The locking plate is fixedly installed at the end of the transmission rod away from the locking head. The locking bolt is threadedly connected to the locking plate, and the end of the locking bolt abuts against the top wall of the foot pedal.

[0017] In one embodiment, a handle extending radially along the shovel is fixedly provided on the shovel bar.

[0018] Compared with existing technologies, the soil sampling device of this application has the following advantages:

[0019] This application utilizes a guide within the inner cavity of the shovel head. Due to the inclined design of the guide, during soil extraction, the shovel head is vertically inserted into the soil. The soil flows along the inclined surface of the guide, over the guide body, and into the inner cavity of the shovel head. When the shovel head is pulled out upwards, the longitudinal section formed by the guide and the shovel head is hook-shaped, thus preventing the soil in the inner cavity from falling downwards. During extraction, the guide provides an upward lifting force to the soil in the inner cavity of the shovel head. The adhesion of the soil at the point where the ground meets the soil exerts a pulling force, causing the soil to tear at the second end of the guide, thereby retaining the soil within the inner cavity of the shovel head. This achieves soil sampling and eliminates the risk of soil detaching from the inner cavity of the shovel head due to adhesion to the ground, as is present in existing technologies.

[0035] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] like Figure 1 As shown, it includes a shovel bar 1 and a shovel head 2, wherein the shovel head 2 is installed at one end of the shovel bar 1. In this embodiment, the shovel bar 1 and the shovel head 2 are detachably connected.

[0037] It is worth noting that the detachable connection between the shovel handle 1 and the shovel head 2 is mainly to facilitate the removal of soil from inside the shovel head 2.

[0038] Also includes grip 6, such as Figure 1 and Figure 6 As shown, the handle 6 is installed at the end of the shovel 1 away from the shovel head 2. Specifically, the handle 6 extends radially along the shovel 1, and the handle 6 facilitates the insertion of the shovel head 2 into the soil or the removal of the shovel head 2 from the soil.

[0039] Normally, a downward pressure needs to be applied to the handle 6 by hand to push the shovel head 2 into the soil. However, the hand has less strength than the foot, making it difficult for the shovel head 2 to penetrate hard soil. Therefore, in this embodiment, if... Figure 3 As shown, the shovel 1 has a foot pedal 5 extending radially outward along the shovel 1 on its peripheral wall. When collecting soil, the foot steps on the foot pedal 5 and applies downward pressure, thereby sending the shovel head 2 into the soil.

[0040] Conventional archaeological soil sampling devices typically use the Luoyang shovel. The shovel head is cylindrical or semi-enclosed, which requires a high level of skill from the user. While it is easy to insert the shovel head into the soil during soil extraction, when the shovel is pulled out, the smooth inner wall and high adhesion between soil particles can cause the soil to remain stuck to the ground and be difficult to pull out with the shovel head.

[0041] Therefore, in this embodiment, in order to solve the problem that the soil is difficult to remove from the surface, such as Figure 2 and Figure 3As shown, a guide 3 is provided in the inner cavity of the shovel head 2. The guide 3 is inclined along the axial direction of the shovel handle 1. It is worth noting that the guide 3 is provided with a first end and a second end. The projection of the first end on the axis of the shovel handle 1 is farther from the handle 6 than the projection of the second end on the axis of the shovel handle 1. The distance from the first end of the guide 3 to the axis of the shovel handle 1 is greater than the distance from the second end of the guide 3 to the axis of the shovel handle 1.

[0042] Specifically, the guide 3 is installed on the side wall of the inner cavity of the shovel head 2. The first end of the guide 3 is connected to the inner wall of the shovel head 2, and the second end of the guide 3 is close to one side of the axis of the shovel head 2. A guide slope 31 is formed on the guide 3.

[0043] During soil sampling, the shovel head 2 is placed on the ground, and a downward pressure is applied to the shovel head 2 by stepping on the pedal 5. At this time, the soil flows into the inner cavity of the shovel head 2 along the inclined surface of the guide 3, thus leaving the soil in the inner cavity of the shovel head 2. When the shovel head 2 is removed from the ground, since the guide inclined surface 31 is set at an angle, the guide inclined surface 31 will give the soil in the inner cavity of the shovel head 2 an upward lifting force, and the ground will give the soil a downward pulling force, which will cause the soil to tear at the horizontal plane at the second end of the guide 3, further leaving the soil in the inner cavity of the shovel head 2.

[0044] Specifically, in this embodiment, the guide 3 and the shovel head 2 are integrally molded, and the longitudinal section of the guide 3 and the shovel head is hook-shaped.

[0045] To reduce the obstruction of the guide ramp 31 from soil entering the inner cavity of the shovel head 2, in this embodiment, as follows: Figure 3 As shown, the cross-section of the guide 3 is a transverse U-shape. Specifically, the cross-sectional area of ​​the guide 3 gradually decreases along the axis of the shovel rod 1 towards the shovel head. At this time, the soil that first enters the shovel head 2 contacts the first end of the guide 3 and is sheared by the first end. Then, the soil is guided upward to facilitate the soil entering the inner cavity of the shovel head 2.

[0046] In order to improve the lifting effect of the guide 3 on the soil, in this embodiment, the guide 3 is also provided with an obstruction plane 32. Specifically, the obstruction plane 32 is set horizontally and is connected to the side wall of the inner cavity of the shovel head 2 along the radial direction of the second end of the guide 3.

[0047] As the shovel head 2 is lifted upwards, the obstructing plane 32 applies a lifting force to the soil inside the shovel head 2 cavity.

[0048] To facilitate the removal of soil from the shovel head 2, in this embodiment, as follows: Figure 2 , Figure 3 and Figure 4As shown, the shovel head 2 includes a cutting section 21 and a window section 22. The window section 22 is located between the cutting section 21 and the shovel handle 1. The cutting section 21 and the window section 22 are fixed to the shovel handle 1 by a locking member 4. When it is necessary to remove the soil, the locking member 4 is used to release the fixing of the cutting section 21 and the window section 22, and the window section 22 is removed from the cutting section 21, thereby exposing the soil inside the shovel head 2, so that soil sampling can be realized.

[0049] The cutting section 21 is mainly used to cut the soil on the ground. The guide 3 is installed on the inner wall of the cutting section 21 so as to gather the cut soil into the inner cavity of the shovel head 2.

[0050] Specifically, the cutting part 21 includes a support 211, which is cylindrical. One end wall of the support 211 is provided with a cutting blade 214, which is used to cut the soil. The cutting part 21 also includes a sealing piece 212 extending along the axial direction of the shovel handle 1 to one side. The window part 22 is provided with an opening 221 on one side. The cross-section of the window part 22 is C-shaped. The sealing piece 212 on the cutting part 21 is inserted into the opening 221 to make the window part 22 compensate into a cylindrical structure so as to facilitate soil storage.

[0051] In order to fix the cutting part 21 and the window part 22 to the shovel rod 1, in this embodiment, as follows: Figure 3 and Figure 4 As shown, the locking component 4 includes a through hole 41, a transmission rod 42, a locking head 43, a locking plate 44, and a locking bolt 45. The through hole 41 is provided on the window portion 22 and extends through the window portion 22 along the axial direction of the window portion 22. The transmission rod 42 is installed in the through hole 41. The locking head 43 is connected to one end of the transmission rod 42 and is used to hook the support seat 211. The other end of the transmission rod 42 passes through the foot pedal 5 and extends upward. The locking plate 44 is fixedly installed on the foot pedal 5. The locking bolt 45 is threadedly connected to the foot pedal 5 so that the end wall of the locking bolt 45 abuts against the top wall of the foot pedal 5.

[0052] With the above configuration, after the sealing piece 212 on the support 211 is inserted into the opening 221 of the window 22, the cutting part 21 and the window 22 form a complete shovel head. Then, the locking head 43 hooks the support 211, so that the sealing piece 212 and the end wall of the window 22 abut against the bottom wall of the foot pedal 5. Then, by rotating the locking bolt 45, the locking bolt 45 abuts against the foot pedal 5, so that the locking plate 44 moves away from the shovel head 2 along the axial direction of the shovel bar 1, thereby fixing the shovel head 2 to the bottom of the foot pedal 5.

[0053] Specifically, the locking plate 44 is provided with a threaded hole 441, and the locking bolt 45 passes through the threaded hole 441 and is threadedly connected to the threaded hole 441.

[0054] To facilitate the hooking of the support 211, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the outer wall of the support 211 is provided with a locking groove 213 recessed in the guide member 3, wherein the locking head 43 is inserted into the locking groove 213, so that the locking head 43 abuts against the top wall of the locking groove 213. The locking head 43 is hidden in the locking groove 213, which can reduce the obstruction caused by the locking head 43 to soil shear.

[0055] In order to fix the cutting part 21, in this embodiment, as follows: Figure 3 As shown, the sealing plate 212 is provided with a plug groove 2121 arranged along the axial direction of the shovel rod 1, and the bottom wall of the foot pedal 5 is fixedly provided with a plug post 51 arranged along the axial direction of the shovel rod 1. When the shovel head 2 and the shovel rod 1 are engaged, the plug post 51 is inserted into the plug groove 2121.

[0056] It is worth noting that the cooperation between the plug post 51 and the transmission rod 42 can restrict the relative movement of the cutting part 21 and the window part 22 along the radial direction of the shovel rod 1, thereby restricting the opening of the inner cavity of the shovel head 2.
