Description

Technical Field

[0001] This application relates to the technical field of soil sampling, and in particular to a soil sampler with adjustable depth. Background Technology

[0002] Soil sampling is an important step in the analysis of the physicochemical properties of soil, such as organic matter, nutrient content, and particle size distribution. The quality of soil sample collection is a crucial prerequisite for the accuracy of experimental analysis results. In environmental geological surveys, soil samplers are widely used as common tools for sampling soil in the area to be investigated, and there are currently many types of equipment used for soil collection.

[0003] In related technologies, the device is embedded into the location where soil sampling is required by using a positioning cone. The cone-shaped bottom of the positioning cone can improve the stability of the device during operation. At the same time, when the drive motor starts, the threaded rod is connected to the platform by a thread. The rotation of the threaded rod causes the lifting plate at the upper end of the drive motor to move up and down with the movement of the threaded rod. This allows the sampling head at the lower end to descend and rotate simultaneously, which can improve the sampling stability and efficiency of the device.

[0004] However, because the positioning cone is inserted to a considerable depth, pulling it out after soil sampling requires significant physical effort, hindering its rapid removal and thus impeding the use of the sampler and reducing its efficiency. Therefore, those skilled in the art have provided an adjustable-depth soil sampler to address the problems mentioned in the background section. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides an adjustable-depth soil sampler.

[0006] The adjustable-depth soil sampler provided in this application adopts the following technical solution:

[0007] An adjustable-depth soil sampler includes a sampling frame. Base plates are fixed to the bottom of both sides of the sampling frame. Insert rods are interlocked between the two base plates. Movable plates are fixed to the top ends of the two insert rods. One side of the two base plates is fixedly connected via a U-shaped frame. Bearing seats are fixed to both sides of the top end of the U-shaped frame. A rotating shaft is rotatably connected between the two bearing seats. Two rotating rods are sleeved on the outer wall of the rotating shaft. A striking plate that abuts against the movable plate is fixed to one end of each rotating rod. A footplate is sleeved on the middle of the outer wall of the rotating shaft.

[0008] Two sliding components are respectively disposed at one end of two moving plates. Both sliding components are connected to the sampling frame and are used to support the sliding of the moving plates.

[0009] Two reset components are respectively located on both sides of the top of the U-shaped frame, and the two reset components are respectively connected to the two ends of the rotating shaft.

[0010] By adopting the above technical solution, the rotating shaft is driven by the pedal, which in turn drives the rotating plate to rotate, causing the plate to strike the moving plate upward, thereby driving the insertion rod upward, facilitating the quick removal of the insertion rod, thus facilitating the use of the sampler and improving its efficiency.

[0011] Preferably, the sliding assembly includes a first slider fixedly disposed at one end of the moving plate, and the side wall of the sampling frame is provided with a first groove for the first slider to slide.

[0012] By adopting the above technical solution and with the cooperation of the sliding components, the moving plate can be easily supported, and the movement of the moving plate can be kept stable.

[0013] Preferably, the reset assembly includes a first connecting rod fixedly disposed at the end of the rotating shaft, a second connecting rod hinged to one end of the first connecting rod, a second slider hinged to one end of the second connecting rod, and a second sliding groove for the second slider to slide at the top of the U-shaped frame, the second sliding groove being fixedly connected to the second slider by a spring.

[0014] By adopting the above technical solution and with the cooperation of the reset component, it is convenient to drive the shaft to reset, that is, to drive the pedal to reset.

[0015] Preferably, an electric telescopic rod is fixed to the bottom end of the sampling frame, and a sampling plate is fixed to the telescopic end of the electric telescopic rod. The sampling plate is connected to the sampling frame through a support assembly. A drive motor is fixed to the bottom end of the sampling plate, and a sampling drill bit is fixed to the output shaft of the drive motor. A support frame is fixed to the top end of the sampling frame, and a take-up roller is rotatably connected inside the support frame. A scale fixed to the sampling plate is wound around the outer wall of the take-up roller, and an elastic component that drives the take-up roller to move is provided on one side of the support frame.

[0016] By adopting the above technical solution, when the sampling drill bit moves downward to take a sample, the drilling depth of the sampling drill bit can be easily measured with the cooperation of the take-up roller and the scale, thereby facilitating soil sampling at different depths and improving soil sampling efficiency.

[0017] Preferably, the support assembly includes a third slider fixedly disposed on both sides of the sampling plate, and a third groove for sliding the third slider is provided on both sides of the inner wall of the sampling frame.

[0018] By adopting the above technical solution and with the cooperation of the support components, it is convenient to support the sampling plate.

[0019] Preferably, the elastic component includes a fixed box fixedly disposed on one side of the support frame, and a coil spring fixed inside the fixed box and fixed to the take-up roller.

[0020] By adopting the above technical solution and with the cooperation of the elastic components, the rotation of the take-up roller can be easily driven, thereby facilitating the winding of the scale.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. This adjustable-depth soil sampler, during sampling, places the sampling frame in the sampling position, then inserts the probe into the soil to fix the sampling frame and collect the soil sample. After sampling, the operator steps on the pedal, causing it to rotate downwards. The pedal drives the rotating shaft to rotate, which in turn drives the rotating rod to rotate upwards. The rotating rod then drives the impact plate to rotate upwards, striking the moving plate and causing it to move upwards. The moving plate then drives the probe upwards. The reset component automatically resets after each pedal step, facilitating the next step. Repeated pedal steps allow the probe to be easily and quickly removed, thus simplifying the use of the sampler and improving its efficiency.

[0023] 2. This adjustable-depth soil sampler, once the sampling frame is fixed, moves the sampling plate downwards under the action of the electric telescopic rod. The sampling plate drives the drive motor and sampling drill bit downwards. Simultaneously, the drive motor rotates the sampling drill bit, allowing it to drill into the soil for sampling. As the sampling plate moves downwards, it pulls the scale. When the bottom of the sampling drill bit is flush with the bottom of the sampling frame, the scale is at zero. As the sampling drill bit moves downwards, the scale also extends accordingly, allowing the drilling depth of the sampling drill bit to be measured. This facilitates soil sampling and improves soil sampling efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an adjustable-depth soil sampler. (Refer to...) Figure 1-4 An adjustable-depth soil sampler includes a sampling frame 1, with base plates 2 fixed to the bottom of both sides of the sampling frame 1. Insert rods 3 are inserted and connected to both base plates 2. Movable plates 4 are fixed to the top of both insert rods 3. One side of the two base plates 2 is fixedly connected by a U-shaped frame 5. Bearing seats 6 are fixed to both sides of the top of the U-shaped frame 5. A rotating shaft 7 is rotatably connected between the two bearing seats 6. Two rotating rods 8 are sleeved on the outer wall of the rotating shaft 7. A striking plate 9 that abuts against the movable plate 4 is fixed to one end of each rotating rod 8. A foot pedal 10 is sleeved on the middle of the outer wall of the rotating shaft 7.

[0031] Two sliding components 11 are respectively disposed at one end of the two moving plates 4. Both sliding components 11 are connected to the sampling frame 1 and are used to support the sliding of the moving plates 4.

[0032] Two reset components 12 are respectively located on both sides of the top of the U-shaped frame 5, and the two reset components 12 are respectively connected to the two ends of the rotating shaft 7.

[0033] In this embodiment, during sampling, the sampling frame 1 is placed at the sampling position, and then the insertion rod 3 is inserted into the soil to fix the sampling frame 1 and sample the soil. After sampling is completed, the personnel step on the pedal 10, causing the pedal 10 to rotate downwards. The pedal 10 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the rotating rod 8 to rotate upwards, and the rotating rod 8 drives the impact plate 9 to rotate upwards. During the rotation of the impact plate 9, it strikes the moving plate 4, which in turn drives the moving plate 4 to move upwards. The moving plate 4 drives the insertion rod 3 to move upwards. The reset component 12 is set to automatically reset after each step of the pedal 10, making it convenient for the next step of the pedal 10. In this way, the insertion rod 3 can be pulled out by repeated stepping on the pedal 10, which facilitates the quick removal of the insertion rod 3, thereby facilitating the use of the sampler and improving the efficiency of the sampler.

[0034] In a further embodiment, such as Figure 1 As shown, the sliding assembly 11 includes a first slider 111 fixedly disposed at one end of the moving plate 4, and a first groove 112 for the first slider 111 to slide on the side wall of the sampling frame 1.

[0035] In this embodiment, when the impact plate 9 drives the moving plate 4 to move upward, the sliding cooperation of the first slider 111 and the first groove 112 facilitates auxiliary support for the moving plate 4 and maintains the stability of the moving plate 4.

[0036] In a further embodiment, such as Figure 2 As shown, the reset assembly 12 includes a first connecting rod 121 fixedly disposed at the end of the rotating shaft 7. A second connecting rod 122 is hinged to one end of the first connecting rod 121. A second slider 123 is hinged to one end of the second connecting rod 122. A second slide groove 124 is provided at the top of the U-shaped frame 5 for the second slider 123 to slide. The second slide groove 124 is fixedly connected to the second slider 123 by a spring 125.

[0037] In this embodiment, when a person steps on pedal 10, pedal 10 drives the rotation of shaft 7, shaft 7 drives the rotation of first connecting rod 121, first connecting rod 121 pulls the movement of second connecting rod 122, second connecting rod 122 drives the movement of second slider 123, and second slider 123 stretches spring 125 during movement. When the person releases pedal 10, under the elastic action of spring 125, second slider 123 is reset, second slider 123 is reset, second connecting rod 122 is reset, second connecting rod 122 is reset, first connecting rod 121 is reset, first connecting rod 121 is reset, and thus pedal 10 is reset, making it convenient for the next step on pedal 10.

[0038] In a further embodiment, such as Figure 3 As shown, an electric telescopic rod 13 is fixed to the bottom of the sampling frame 1, and a sampling plate 14 is fixed to the telescopic end of the electric telescopic rod 13. The sampling plate 14 is connected to the sampling frame 1 through a support assembly 15. A drive motor 16 is fixed to the bottom of the sampling plate 14, and a sampling drill bit 17 is fixed to the output shaft of the drive motor 16. A support frame 18 is fixed to the top of the sampling frame 1. A take-up roller 19 is rotatably connected inside the support frame 18. A scale 20 fixed to the sampling plate 14 is wound around the outer wall of the take-up roller 19. An elastic component 21 that drives the take-up roller 19 to move is provided on one side of the support frame 18.

[0039] In this embodiment, after the sampling frame 1 is fixed, the sampling plate 14 moves downward under the movement of the electric telescopic rod 13. The sampling plate 14 drives the drive motor 16 and the sampling drill bit 17 to move downward. At the same time, under the operation of the drive motor 16, the sampling drill bit 17 is rotated, so that the sampling drill bit 17 can be drilled into the soil to sample the soil. When the sampling plate 14 moves downward, it pulls the scale 20. The top of the sampling frame 1 has a through hole for the scale 20 to pass through. The through hole facilitates the pulling of the scale 20. When the bottom end of the sampling drill bit 17 is flush with the bottom end of the sampling frame 1, the scale 20 is at zero. When the sampling drill bit 17 moves downward, the scale 20 is also pulled open accordingly. The drilling depth of the sampling drill bit 17 can be measured by the scale 20, which facilitates soil sampling and improves soil sampling efficiency.

[0040] In a further embodiment, such as Figure 3 As shown, the support assembly 15 includes a third slider 151 fixedly disposed on both sides of the sampling plate 14, and a third groove 152 for sliding the third slider 151 is provided on both sides of the inner wall of the sampling frame 1.

[0041] In this embodiment, when the sampling plate 14 moves up and down, it drives the third slider 151 to slide in the third slide groove 152. With the cooperation of the third slider 151 and the third slide groove 152, it is convenient to provide auxiliary support for the sampling plate 14 and maintain the stability of the movement of the sampling plate 14.

[0042] In a further embodiment, such as Figure 4 As shown, the elastic component 21 includes a fixed box 211 fixedly disposed on one side of the support frame 18, and a coil spring 212 fixed inside the fixed box 211 and fixed to the take-up roller 19.

[0043] In this embodiment, when the sampling plate 14 drives the sampling drill bit 17 to move upward, the scale 20 is in a relaxed state. Then, under the elastic action of the coil spring 212, the winding roller 19 is driven to rotate and reset. The scale 20 can be wound up while the winding roller 19 is rotating.

[0044] The implementation principle of an adjustable-depth soil sampler according to an embodiment of this application is as follows: During sampling, the sampling frame 1 is placed at the sampling position, and then the insertion rod 3 is inserted into the soil to fix the sampling frame 1. Under the movement of the electric telescopic rod 13, the sampling plate 14 moves downward. The sampling plate 14 drives the drive motor 16 and the sampling drill bit 17 to move downward. At the same time, under the operation of the drive motor 16, the sampling drill bit 17 is rotated, so that the sampling drill bit 17 can be drilled into the soil to sample the soil. When the sampling plate 14 moves downward... By pulling the scale 20, the drilling depth of the sampling drill bit 17 can be measured, facilitating soil sampling and improving sampling efficiency. After sampling, the electric telescopic rod 13 reverses its movement, causing the sampling drill bit 17 to return to its original position. At this time, the scale 20 is in a relaxed state. Then, under the elastic action of the coil spring 212, the winding roller 19 rotates and returns to its original position. The winding roller 19 can wind up the scale 20 during rotation, making it convenient to use. When it is necessary to remove the sampling frame 1... When the person steps on pedal 10, pedal 10 drives the rotation of shaft 7, which in turn drives the rotation of first connecting rod 121. First connecting rod 121 pulls the movement of second connecting rod 122, which in turn drives the movement of second slider 123. During its movement, second slider 123 stretches spring 125. When the person releases pedal 10, the elasticity of spring 125 causes second slider 123 to return to its original position. Second slider 123 then causes second connecting rod 122 to return to its original position, which in turn causes first connecting rod 121 to return to its original position. The first connecting rod 121 drives the rotating shaft 7 to reset, thereby driving the pedal 10 to reset, making it convenient for the next step of the pedal 10. In this way, each step of the pedal 10 will drive the rotating shaft 7 to rotate, the rotating shaft 7 will drive the rotating rod 8 to rotate upward, the rotating rod 8 will drive the impact plate 9 to rotate upward, and the impact plate 9 will hit the moving plate 4 during rotation, thereby driving the moving plate 4 to move upward, and the moving plate 4 will drive the insertion rod 3 to move upward, so that the insertion rod 3 can be pulled out quickly, which facilitates the use of the sampler and improves the efficiency of the sampler.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
