Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampler technology, and is a sampler used for soil testing. Background Technology
[0002] A soil sampler is a tool used to obtain soil samples. Commonly used ones include soil drills, shovels, and spades. A soil drill consists of a drill bit and a handle made of a hard material (steel or hard plastic). The drill bit is often spiral or cylindrical. The tip of a spiral drill bit has a pair of sharp cutting edges that can rotate and cut into the soil. Next to the cutting edges is a large cavity for holding soil. As the handle is rotated, the drill bit goes down into the soil surface, allowing soil samples from the desired soil layer to be introduced into the cavity.
[0003] In traditional soil sampling, a sampler needs to be manually inserted into the soil to take a sample. After the sample is taken, the sampler needs to be manually pulled out, which is a cumbersome and labor-intensive process. Utility Model Content
[0004] This invention addresses the problem that traditional soil sampling requires manual insertion of a sampler into the soil, and after sampling, the sampler head needs to be manually pulled out, making the sampling process cumbersome and increasing manual labor intensity. Therefore, this invention provides a sampler for soil testing.
[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:
[0006] This utility model provides a sampler for soil testing, the sampler for soil testing comprising:
[0007] A fixed base, wherein a handle is fixedly connected to the side surface of the fixed base, and a protective shell is fixedly connected to the top side surface of the fixed base;
[0008] A pushing mechanism is mounted on the surface of a fixed base. The pushing mechanism includes a guide column, a top plate, a hydraulic cylinder, a bottom plate, and a lifting assembly. The guide column slides through the surface of the fixed base. The top plate is fixedly connected to the top of the guide column. A hydraulic cylinder is fixedly connected to the top side of the top plate. The bottom plate is fixedly connected to the bottom end of the guide column. A foot pedal is fixedly connected to the side surface of the bottom plate. The lifting assembly is mounted on the surface of the bottom plate, and a plug-in column is fixedly connected to the bottom side of the bottom plate.
[0009] A sampling mechanism, which is mounted on a fixed base surface, is used for soil sampling.
[0010] An anti-deviation mechanism is installed on the surface of the sampling mechanism.
[0011] Furthermore, there are four guide posts, which slide through the four corner positions of the fixed base.
[0012] Furthermore, a push plate is fixedly connected to the output end of the hydraulic cylinder, and the surface of the push plate is connected to the fixed seat by bolts.
[0013] Furthermore, the lifting assembly includes an electric push rod and a lifting plate. The electric push rod is fixedly installed on the top side of the base plate, and the output end of the electric push rod is fixedly connected to the lifting plate. The lifting plate is engaged with the bottom surface of the base plate.
[0014] Furthermore, the bottom plate has a U-shaped cross-section when viewed from above, and several plug-in posts are evenly distributed on the bottom side of the bottom plate, with foot pedals symmetrically distributed on both sides of the bottom plate.
[0015] Furthermore, the sampling mechanism includes a servo motor, a rotating column, a threaded cylinder, and a sampling shell. The servo motor is fixedly connected to the top surface of the fixed base. The output end of the servo motor is connected to the rotating column.

[0019] Furthermore, a battery and a servo motor are fitted inside the protective shell, and the battery is electrically connected to the servo motor, the hydraulic cylinder, and the electric push rod.
[0020] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0021] The positive and progressive effects of this utility model are as follows:
[0022] The aforementioned soil sampler, during sampling, involves the user stepping on a foot pedal. A hydraulic cylinder pushes a fixedly connected push plate, which in turn moves a fixed seat downwards. The fixed seat moves along the guide column surface, ensuring stable guidance. Simultaneously, the fixed seat drives the sampling mechanism to collect soil samples, facilitating the sampling operation. After sampling, an electric push rod pushes a fixedly connected lifting plate, which in turn pushes the ground and lifts the base plate. The top plate then lifts the insertion column off the ground, allowing the sampler to be moved. Through the sampling mechanism, the sampling shell penetrates the soil. As the rotating column drives the sampling shell to rotate, an anti-deviation cylinder limits its movement, reducing eccentricity and ensuring stable downward movement. After sampling, the sampling shell is removed, the retaining plate is disassembled, and the side surface of the sampling shell is open for easy removal of the collected soil.

[0035] like Figure 1-3 As shown, the sampler for soil testing includes:
[0036] A fixed base 1, a handle 2 is fixedly connected to the side surface of the fixed base 1, and a protective shell 4 is fixedly connected to the top side surface of the fixed base 1;
[0037] A pushing mechanism 3 is mounted on the surface of a fixed base 1. The pushing mechanism 3 includes a guide column 31, a top plate 32, a hydraulic cylinder 33, a bottom plate 35, and a lifting assembly. The guide column 31 slides through the surface of the fixed base 1. The top of the guide column 31 is fixedly connected to the top plate 32. The top side of the top plate 32 is fixedly connected to the hydraulic cylinder 33. The bottom end of the guide column 31 is fixedly connected to the bottom plate 35. A foot pedal 38 is fixedly connected to the side surface of the bottom plate 35. The lifting assembly is mounted on the surface of the bottom plate 35, and a plug-in column 39 is fixedly connected to the bottom side of the bottom plate 35.
[0038] During sampling, the user steps on the foot pedal 38 to activate the hydraulic cylinder 33. The hydraulic cylinder 33 pushes the fixedly connected push plate 34 to move, and the push plate 34 drives the fixed seat 1 to move down. The fixed seat 1 moves along the surface of the guide column 31 to achieve stable guiding movement of the fixed seat 1. At the same time, the fixed seat 1 drives the sampling mechanism 6 to perform soil sampling, which facilitates the sampling operation.
[0039] Sampling mechanism 6, which is mounted on the surface of fixed base 1, is used for soil sampling;
[0040] Anti-deviation mechanism 7 is installed on the surface of sampling mechanism 6.
[0041] The number of guide posts 31 is four, and the four guide posts 31 slide through the four corner positions of the fixed base 1.
[0042] The output end of the hydraulic cylinder 33 is fixedly connected to a push plate 34, and the surface of the push plate 34 is connected to the fixed seat 1 by bolts.
[0043] The lifting assembly includes an electric push rod 36 and a lifting plate 37. The electric push rod 36 is fixedly installed on the top side of the base plate 35, and the output end of the electric push rod 36 is fixedly connected to the lifting plate 37. The lifting plate 37 is engaged with the bottom surface of the base plate 35.
[0044] When the electric push rod 36 is activated, it pushes the fixedly connected lifting plate 37 to move. The lifting plate 37 pushes the ground, which in turn supports the base plate 35. The top plate 32 then lifts the insertion post 39 off the ground, making it easier to move the sampler.
[0045] The bottom plate 35 has a U-shaped cross-section when viewed from above. Several plug-in posts 39 are evenly distributed on the bottom side of the bottom plate 35, and foot pedals 38 are symmetrically distributed on both sides of the bottom plate 35.
[0046] The sampling mechanism 6 includes a servo motor 61, a rotating column 62, a threaded cylinder 63, and a sampling shell 64. The servo motor 61 is fixedly connected to the top surface of the fixed base 1. The output end of the servo motor 61 is connected to the rotating column 62. The bottom end of the rotating column 62 is threadedly fitted with the threaded cylinder 63. The bottom end of the threaded cylinder 63 is fixedly connected to the sampling shell 64.
[0047] A card plate 66 is connected to the front surface of the sampling shell 64. The sampling shell 64 and the card plate 66 constitute a sampling head for soil storage sampling. Sawtooth blades 65 are evenly installed on the bottom sides of both the sampling shell 64 and the card plate 66.
[0048] The serrated blade 65 facilitates the insertion of the sampling shell 64 into the ground. By activating the servo motor 61, the servo motor 61 drives the rotating column 62 to rotate, which in turn drives the sampling shell 64, which is fixedly connected to the bottom, to rotate. The sampling shell 64 then penetrates into the soil. During the rotation of the sampling shell 64 driven by the rotating column 62, the anti-deviation cylinder 73 provides a limit to reduce the possibility of eccentricity during the rotation of the sampling shell 64, ensuring that the sampling shell 64 moves down stably. After sampling, the sampling shell 64 is removed, and the disassembly plate 66 is detached from the sampling shell 64. The side surface of the sampling shell 64 is open, making it easy to remove the collected soil.
[0049] The anti-deviation mechanism 7 includes a slide cylinder 71, a connecting column 72, and an anti-deviation cylinder 73. The slide cylinder 71 is sleeved on the surface of the guide column 31. The connecting column 72 is fixedly connected to the side surface of the slide cylinder 71. The anti-deviation cylinder 73 is fixedly connected to the other end of the connecting column 72. The anti-deviation cylinder 73 is sleeved on the surface of the threaded cylinder 63.
[0050] The number of connecting posts 72 is four, and the four connecting posts 72 are symmetrically arranged on the side surface of the anti-deviation cylinder 73.
[0051] The protective shell 4 houses a battery 5 and a servo motor 61. The battery 5 is electrically connected to the servo motor 61, the hydraulic cylinder 33, and the electric push rod 36.
[0052] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
