Description

Technical Field

[0001] The present invention relates to the technical field of soil collection and detection, and in particular to a portable soil collection, analysis and detection device. Background Art

[0002] Soil is a loose and porous substance that exists on the surface of the earth and can grow green plants. It is composed of various granular minerals, organic matter, water, air, microorganisms, etc. The physical and chemical properties of soil change with the depth of the soil layer. In many fields such as soil science, agronomy, water conservancy, and environmental testing, in order to better study environmental changes, it is often necessary to sample and study soil at all depths. For the surface soil, it is only necessary to manually collect and test it. However, in order to better sample and test deep soil, it is particularly important to design a soil detector that can quickly and easily collect deep soil.

[0003] At present, the ordinary soil detectors already available on the market often have a relatively simple structural design, which is not convenient for collecting deep soil. If it is necessary to test deep soil, some large equipment is needed for processing, and large equipment is not easy to carry, resulting in large limitations when collecting and testing soil. In addition, some equipment vibrates too much when sampling soil, resulting in unstable operation of the entire equipment. The operator needs to hold it by hand to fix it, which makes the sampling process relatively cumbersome. Therefore, a portable soil collection, analysis and detection device is proposed to solve the above problems. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-9 , a portable soil collection and analysis device, including a folding and laying device 1, see Figure 3 , used for contacting and fixing with the ground; the folding and paving device 1 includes a connecting plate 101, to which a left flat plate 102 and a right flat plate 103 are connected. The left flat plate 102 and the right flat plate 103 are mainly in contact with the soil surface. The bottoms of the left flat plate 102 and the right flat plate 103 are connected with inserts 106, which are directly inserted into the bottom surface using the conical structure of the inserts 106 to achieve fixation. A pull ring 105 is connected to the left flat plate 102 and the right flat plate 103. The setting of the pull ring 105 is mainly for the convenience of carrying in the folded state. A contact sleeve 114 is connected to the connecting plate 101 through a connecting rod. The circular contact sleeve 114 mainly provides a sampling range and provides a circular space to facilitate later sampling and detection. A snap-fit ​​device is provided on the left flat plate 102 and the right flat plate 103.

[0034] In this embodiment, please refer to Figure 4 and Figure 5 The snap-fit ​​device includes a snap-fit ​​strip 108 and a snap-fit ​​holder 112. The snap-fit ​​strip 108 is mounted on the right flat panel 103. An insertion strip 109 is slidably connected to the snap-fit ​​strip 108. A snap-fit ​​spring 110 is connected to one side of the insertion strip 109. A spring holder 111 is connected to one side of the snap-fit ​​spring 110. The spring holder 111 is connected to the snap-fit ​​strip 108. The snap-fit ​​holder 112 is connected to the left flat panel 102. A snap-fit ​​slot 113 is formed on the snap-fit ​​holder 112 to cooperate with the insertion strip 109 and the snap-fit ​​strip 108. Using the snap-fit ​​device, when an operator presses the insertion strip 109, the snap-fit ​​spring 110 is squeezed and contracted, causing the insertion strip 109 to disengage from the snap-fit ​​slot 113 of the snap-fit ​​holder 112, thereby achieving automatic expansion from the contracted state.

[0035] For further information, see Figure 3 The connecting plate 101 is connected to an arc-shaped plate 107, which is provided with a connecting spring 104. One end of the connecting spring 104 is connected to the left flat plate 102, and the other end of the connecting spring 104 is connected to the right flat plate 103. The elastic force of the two connecting springs 104 automatically pushes the left and right flat plates 102 and 103 apart, causing them to fall flat on the surrounding soil. The two inserts 106 are then directly inserted into the soil, providing a two-way soil insertion and fixation for the entire device.

[0036] For further information, see Figure 6 , the buffer support device 2 is used to reduce the vibration caused by the in-depth sampling process equipment; the buffer support device 2 includes a sliding rod 203, two support frames 201 are connected to the sliding rod 203, the support frames 201 are connected to the in-depth device 3, a top plate 202 is installed on the sliding rod 203, one side of the top plate 202 is connected to a buffer spring 204, one end of the buffer spring 204 is connected to the left flat plate 102, and a slide groove 205 is provided in the left flat plate 102, and the two ends of the sliding rod 203 are slidably connected in the slide groove 205. During the operation of the motor, the whole will generate a lot of vibration. At this time, the vibration force will be transmitted to the connecting sleeve 301, and the vibration force will be transmitted to the two buffer springs 204 via the two support frames 201, thereby providing a buffer force for the operation of the equipment, reducing the sampling and detection errors caused by vibration, and protecting the components of the detection equipment 4, thereby improving the service life and operation stability of the equipment.

[0037] Also, see Figure 6The penetrating device 3 is used to penetrate the soil to perform soil sampling or testing at various depths. The penetrating device 3 includes a connecting sleeve 301, with a shaft 303 slidably connected thereto. The bottom of the shaft 303 is connected to the contact sleeve 114. A drive motor 304 is mounted on the connecting sleeve 301 via a plate. The output end of the drive motor 304 is provided with a control device 302. The drive motor 304 provides power, enabling the control device 302 to penetrate the soil layer during movement. The two shafts 303 provide a certain degree of limit, making the motor operation more stable and providing a certain downward travel distance to ensure that the spring can cushion its movement.

[0038] In addition, see Figure 7-9 The control device 302 includes a rotating sleeve 3021 , one end of which is connected to the output end of the driving motor 304 , and the interior of the rotating sleeve 3021 is slidably connected to a deep shaft tube 3023 via a keyway, and a drill bit 3025 is installed at the bottom of the deep shaft tube 3023 . The rotation of the driving motor 304 will drive the rotation of the rotating sleeve 3021, and the drilling shaft tube 3023 slides inside the rotating sleeve 3021 through a spline, so the rotating sleeve 3021 will synchronously drive the rotation of the drilling shaft tube 3023, and then drive the rotation of the drill bit 3025. The drill bit 3025 penetrates the soil and drills the entire drilling shaft tube 3023 into the deep soil. Therefore, the movement process of the drilling shaft tube 3023 at this time is to rotate and move downward at the same time, and the pressure plate 3022 is elastically connected to the drilling shaft tube 3023 through the return spring 3029, so the pressure plate 3022 will also follow the rotation of the rotating sleeve 3021. A scale line is set on the surface of the rotating sleeve 3021. The display of the scale line can know the depth of the downward movement of the pressure plate 3022, and then the sinking depth of the drill bit 3025.

[0039] It is worth noting that see Figure 7The rotating sleeve 3021 is provided with a linear slot 3024, onto which a pressure plate 3022 is slidably connected. A steel needle 3030 is connected to the pressure plate 3022. A return spring 3029 is attached to the bottom of the steel needle 3030, which is located inside the deep shaft tube 3023. When the operator releases the pressure plate 3022, the elastic force of the return spring 3029 causes the steel needle 3030 to rise and return, preventing it from being tilted. This would interfere with the soil when the entire control device 302 retracts and return, thus damaging the rotating bar 3026. The steel needle 3030 is connected to the rotating bar 3026, which is rotatably connected to the deep shaft tube 3023 via a connecting rod. The deep shaft tube 3023 is equipped with a detection head 3027 and a material removal sleeve 3028. When testing soil directly, the operator pulls up the steel needle 3030 and controls the reverse rotation of the rotating bar 3026, causing the probe head 3027 to directly contact and penetrate the soil layer, thereby achieving testing. The probe head 3027 here operates on a similar principle to the insertion needle 403, also detecting soil moisture and temperature through insertion. The data is ultimately transmitted to the display screen 401 via an electrical connection for display. After moving down to the appropriate depth, when sampling is required, the operator can directly press the pressure plate 3022, driving the steel needle 3030 downward. This downward movement causes the connected rotating bar 3026 to rotate slightly, pulling out the sampling sleeve 3028, thereby contacting the soil side at that depth. Using the tilt of the sampling sleeve 3028, soil is excavated and stored in its internal cavity. Multiple rotating bars 3026 are positioned at different heights, enabling soil testing and sampling at different depths, achieving both sampling and direct testing.

[0040] It is worth noting that, please refer to Figure 6 Testing device 4 is used to test the sampled soil. Testing device 4 includes a display screen 401, which is electrically connected to a pin 403 via a wire 402. A detection head 3027 is electrically connected to display screen 401. To test the soil surface directly, simply insert pin 403 into the soil to be tested. Pin 403 is equipped with a soil temperature and humidity sensor. Upon insertion, the soil temperature and humidity sensor tests the soil and transmits the test results via wire 402 to display screen 401, achieving a digital display and providing the operator with the most intuitive display.

[0041] Working principle: First, the whole device is as follows Figure 2As shown, it is in a folded and contracted state, which is convenient for storage and carrying. Later, when the operator needs to test and sample the soil at that location, he aligns the contact sleeve 114 with the soil part that needs to be tested and sampled, and then presses the insert 109 to squeeze and contract the clamping spring 110, so that the insert 109 is separated from the clamping slot 113 position of the clamping seat 112. At this time, the left plate 102 and the right plate 103 are affected by the elastic force of the two connecting springs 104, which will automatically bounce the two plates apart and make them flat on the surrounding soil. The two inserts 106 are directly inserted into the soil to perform two-way soil insertion and fixation on the entire device. After that, the deep-seated shaft tube 3023 is subjected to gravity and will slide downward, moving the drill bit 3025 to the upper surface of the soil. The two support frames 201 will be affected by the elastic force of the buffer spring 204 to push the top plate 202 to slide, driving it to unfold, forming a Figure 6If the soil surface is to be tested directly, it is only necessary to insert the pin 403 into the soil to be tested. The pin 403 is provided with a soil temperature and humidity sensor. With the insertion of the pin 403, the soil temperature and humidity sensor will detect the soil and transmit the detection results to the display screen 401 through the wire 402 to realize digital display. If the soil depth needs to be sampled or tested, the driving motor 304 needs to be started, and the motor will drive the rotation of the rotating sleeve 3021. The deep-drilling shaft tube 3023 slides inside the rotating sleeve 3021 through a spline, so the rotating sleeve 3021 will synchronously drive the rotation of the deep-drilling shaft tube 3023, and then drive the rotation of the drill bit 3025. The drill bit 3025 is used to penetrate the soil and the entire deep-drilling shaft tube 3023 is drilled into the deep soil. Therefore, the movement process of the deep-drilling shaft tube 3023 at this time is to rotate and move downward at the same time, and the pressure plate 3022 is elastically connected to the deep-drilling shaft tube 3023 through the return spring 3029, so the pressure plate 3022 will also follow the rotating sleeve 3 Scale lines are set on the surface of 021. The scale lines can be used to know the depth of the downward movement of the pressure plate 3022, and then the depth of the sinking of the drill bit 3025. After moving to the appropriate depth, when sampling is required, the operator can directly press the pressure plate 3022 to drive the steel needle 3030 to move downward. During the downward movement, the rotating bar 3026 connected to it will be driven to rotate slightly, and the material collection sleeve 3028 will be pulled out, thereby contacting the side of the soil at this depth. The soil is dug by utilizing the inclination of the material collection sleeve 3028 and stored in the internal cavity of the material collection sleeve 3028. Then, the pressure plate 3022 is released, and the steel needle 3030 is raised and reset with the elastic force of the reset spring 3029. For direct testing, the operator pulls up the steel needle 3030 and controls the reverse rotation of the rotating bar 3026, causing the probe 3027 to directly contact and penetrate the soil layer, thereby completing the test. The probe 3027 operates on a similar principle to the insertion needle 403, also measuring soil moisture and temperature through insertion. The data is then transmitted to the display screen 401 via an electrical connection for display. After the test or sampling is complete, the drive motor 304 rotates in the reverse direction, driving the drill bit 3025 upward. The spiral blades on the drill bit 3025 rotate in the reverse direction, retracting and returning the control device 302 to its original position. The operator can then collect and store the collected soil using the retracted control device 302. During the operation of the motor, a large vibration will be generated. At this time, the vibration force will be transmitted to the connecting sleeve 301, and then transmitted to the two buffer springs 204 through the two support frames 201, thereby providing buffering force for the operation of the equipment, reducing the errors in sampling and detection caused by vibration, and protecting the components of the detection equipment 4, thereby improving the service life and operation stability of the equipment.
