Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a low-carbon and environment-friendly soil sampling device. Background Art

[0002] Soil sampling equipment is a device specially used to collect soil samples. The soil sampling equipment currently on the market uses human-powered or low-power electric systems, which can reduce the use of fossil fuels during use, thereby reducing carbon emissions and achieving a low-carbon and environmentally friendly effect. This type of equipment is widely used in agriculture, environmental monitoring, geological exploration and other fields; For example, the patent title disclosed in the prior art with the announcement number "CN119534002A" is "A soil sampling device for deep soil sampling", which discloses the use of an electric telescopic rod and an output motor to make the drill rod assembly drill into the soil, and when the first drill rod is about to be immersed in the soil, the output motor rotates and the drill rod assembly is extended and retracted, so that the second drill rod is pulled out and locked by the lower card box and the hollow card box, thereby automatically extending the length of the drill rod, so that the sampling personnel do not need to frequently disassemble the motor and assemble and splice the drill rods to achieve automated soil drilling operations, and the pulled-out drill rod part can be collected through automatic reverse operation to automatically shorten the length of the entire drill rod, so that there is no need for personnel to disassemble the drill rod after sampling, thereby greatly reducing the workload of the sampling personnel, and the patent title disclosed in the prior art with the announcement number "CN110926863B" is "A soil sampler", which discloses that through the coordinated use of a fixed sleeve and a soil sampling structure, the power of the feet can be used to achieve rotational soil sampling, without the need for repeated hand movements. The rotation can not only save manpower, but also use the power of the foot to accelerate the speed of inserting into the soil, and the rotating soil-taking method can further quickly insert into the soil, so as to realize fast soil taking and facilitate soil sampling. That is, since a screw rod is rotatably connected inside the fixed sleeve, and a rotating sleeve is threadedly connected to the outside of the screw rod, and the rotating sleeve is limited by sliding with the connecting plate and the fixed sleeve, the screw rod can be rotated inside the fixed sleeve by stepping on the pedal fixed with the connecting plate outside. Since the screw rod is fixed to the rotating rod of the fixed soil-taking ring, the soil-taking ring will also rotate during the rotation of the screw rod. When the soil-taking ring is taking soil, the soil-taking ring rotates, thereby accelerating the entry into the soil, thereby accelerating soil taking, thereby greatly accelerating the soil taking efficiency, and since the first spring is also clamped and fixed between the connecting plate and the fixed plate, the pedal can be automatically restored to its original position through the elastic force of the first spring after the soil taking is completed, thereby facilitating the next soil taking.

[0003] When the soil sampling device in the above-mentioned prior art is in use, the soil sampling ring is moved downward while rotating to enter the soil to sample soil. When the above-mentioned soil sampling device is sampling soft soil, since the soft soil cannot be compacted, the soft soil inside is easy to fall when the soil sampling ring moves upward, thus affecting the sampling operation. Therefore, we propose a low-carbon and environmentally friendly soil sampling device to solve the above-mentioned problems. Summary of the invention

The specific structure is shown in the attached Figure 1-Figure 6 And attached Figure 8 As shown, it includes an outer shell 1 and a support frame 2 installed on the outer side thereof for support, and the motor 3 fixed on the top of the outer shell 1 is connected to the connecting component 9 installed inside the outer shell 1, a fixing column 5 connected to the lower end of the connecting component 9 is installed through the bottom surface of the outer shell 1, and a control handle 4 for controlling the lifting and lowering thereof is rotatably installed through the outer side of the fixing column 5, a connecting head 14 is connected to the inner thread below the fixing column 5, and a fixed sampling arc plate 13 and three movable sampling arc plates 7 are connected to the bottom surface of the connecting head 14, a fixing ring 10 is fixed through the outer side of the fixing column 5, and the lower side of the fixing ring 10 is connected to the movable ring 12 through the supporting component.

[0020] A protrusion 71 is fixed on the top of the mobile sampling arc plate 7, the bottom surface of the connector 14 is fixedly installed with a fixed sampling arc plate 13, a limit rod 141 is installed in a groove on the bottom surface of the connector 14, a protrusion 71 is installed on the outer side of the limit rod 141, and a connecting spring 142 is nested and connected on the outer side of the other end of the limit rod 141. The mobile sampling arc plate 7 forms a sliding structure with the connector 14 through the protrusion 71. The connecting assembly 9 includes a first connecting tube 91, a second connecting tube 92, a connecting column 93 and a reset spring 94. The lower internal clamping and sliding connection of the first connecting tube 91 is the second connecting tube 92, and the lower internal clamping and sliding connection of the second connecting tube 92 is the second connecting tube 92. There is a connecting column 93, the lower end of the connecting column 93 is connected to the fixed column 5, the upper part of the second connecting tube 92 and the interior of the first connecting tube 91, as well as the upper part of the connecting column 93 and the interior of the second connecting tube 92 are connected through a reset spring 94, and three groups of adsorption blocks 121 are installed on the inner wall of the movable ring 12. The movable ring 12 forms a lifting structure through a supporting assembly. The adsorption blocks 121 and the movable sampling arc plate 7 are arranged in a one-to-one correspondence, and the opposite surfaces of the adsorption blocks 121 and the movable sampling arc plate 7 are made of magnet blocks with the same magnetic poles. The supporting assembly includes an electric push rod 11 installed on the bottom surface of the fixed ring 10, and the output end of the electric push rod 11 is connected to the movable ring 12.

[0021] First, move the entire low-carbon and environmentally friendly soil sampling equipment to the working area, then open the support frame 2, and then when sampling the soft soil, manually press the control handle 4 downward, and the control handle 4 drives the fixed column 5 to move downward together. At this time, the fixed column 5 pulls the connecting column 93 and the second connecting tube 92 in the connecting assembly 9 to move downward, and the fixed column 5 drives the mobile sampling arc plate 7 and the fixed sampling arc plate 13 to move downward together through the connecting head 14, and then the mobile sampling arc plate 7 and the fixed sampling arc plate 13 are inserted into the soft soil. At the same time, start the electric push rod 11, and the electric push rod 11 drives the moving ring 12 to rise and fall reciprocatingly. When the moving ring 12 drives the three adsorption blocks 121 on the inside to move downward to the upper and outer sides of the mobile sampling arc plate 7, at this time, since the opposite surfaces of the mobile sampling arc plate 7 and the adsorption block 121 are made of magnet blocks with the same magnetic poles, the adsorption block 121 and the mobile sampling arc plate 7 produce a repulsive force. At this time, the mobile sampling arc plate 7 The upper protrusion 71 slides inwardly on the outer side of the limit rod 141, and the connecting spring 142 is squeezed and stored, and the protrusion 71 drives the movable sampling arc plate 7 to move inward, so that the movable sampling arc plate 7 squeezes the soil inside. When the movable ring 12 rises, the stored force of the connecting spring 142 automatically drives the protrusion 71 and the movable sampling arc plate 7 to move outward and reset. Such repeated operations make the movable sampling arc plate 7 move reciprocatingly inwardly to squeeze the soil, and then when the entire soil sampling equipment samples soft soil, the three groups of movable sampling arc plates 7 can improve the density of the soft soil and prevent the soft soil from falling in the later stage, and then will not affect the sampling operation. After the sampling is completed, the control handle 4 is moved upward, and then the connecting head 14 is manually rotated to separate the connecting head 14 from the fixed column 5, and an external tool is inserted into the connecting head 14 to push out the soil inside the movable sampling arc plate 7 and the fixed sampling arc plate 13, thereby processing the sampled soil.

[0022] Embodiment 2: The low-carbon and environmentally friendly soil sampling equipment in this embodiment, based on the embodiment 1, discloses another support assembly, so that the moving ring 12 can be driven to perform reciprocating lifting without using a power source, which can further save energy and achieve low-carbon and environmental protection. The specific structure is shown in the attached Figure 11-Figure 12As shown, the support assembly includes a manual telescopic rod 22 installed on the bottom surface of the fixed ring 10, the lower end of the manual telescopic rod 22 is connected to the moving ring 12, the outer side of the manual telescopic rod 22 is nested with a support spring 23, a control panel 17 is fixed to the outer side of the moving ring 12, and a circular groove 171 is provided on the upper surface of the control panel 17. A sleeve 24 is rotatably installed inside the horizontal plane of the control handle 4 close to the fixed column 5, a vortex spring 19 is connected to the lower outer side of the sleeve 24, and a connecting rope 20 is wound and connected to the upper outer side of the sleeve 24. The other end of the connecting rope 20 passes through the inside of the control handle 4, and a cross bar 21 is slidably connected to the control handle 4 in the horizontal plane away from the fixed column 5. The cross bar 21 is connected to the other end of the connecting rope 20, and the inner thread of the sleeve 24 is connected to the second threaded rod 18, and the lower part of the second threaded rod 18 is inserted into the groove 171. A limit column 25 is installed on the horizontal plane of the control handle 4 close to the fixed column 5, and a cross block is installed on the upper end of the second threaded rod 18. The limit column 25 is arranged inside the cross block.

[0023] When the movable sampling arc plate 7 and the fixed sampling arc plate 13 are inserted into the soft soil, the cross bar 21 can be manually pulled first, and the cross bar 21 pulls the connecting rope 20, and then the connecting rope 20 drives the sleeve 24 to rotate. At this time, the cross block fixed above the second threaded rod 18 is sleeved on the outside of the limit column 25, so that when the sleeve 24 rotates, it can drive the second threaded rod 18 connected with the internal thread to move downward stably. At this time, the vortex spring 19 accumulates force, and when the second threaded rod 18 descends, it pushes the control plate 17 and the movable ring 12 to move downward. At this time, the manual telescopic rod 22 is stretched, and the support spring 23 accumulates force. When the second threaded rod 18 rises, the mobile ring 12 is automatically driven to rise through the accumulated force of the support spring 23, so that the mobile ring 12 is reciprocatingly lifted and lowered, and then as shown in Example 1, the movable sampling arc plate 7 reciprocatingly moves inward to squeeze the soil to prevent the soft soil from falling later.

[0024] Embodiment 3: The low-carbon and environmentally friendly soil sampling device in this embodiment, based on the embodiment 1, can cut the harder or denser soil, so that the soil sampling device can easily perform sampling operations on the harder or denser soil. For the specific structure, refer to the attached Figure 2 , Attachment Figure 7 and attached Figure 9-10 And attached Fig.13As shown, a bottom ring 8 is fixed to the bottom surface of the fixed sampling arc plate 13, and there is a gap between the top of the bottom ring 8 and the bottom of the movable sampling arc plate 7. A circular ring-shaped accommodating groove 81 is opened on the inner wall of the bottom ring 8, and an elastic rubber film 82 is fixed inside the accommodating groove 81. A steel wire 16 is fixed to the other side of the elastic rubber film 82. Both ends of the steel wire 16 are vertically inserted into the fixed sampling arc plate 13. A first threaded rod 15 is installed on the outer side of the fixed sampling arc plate 13. The outer side of the first threaded rod 15 is threadedly connected with a regulating ring 6. The regulating ring 6 is sleeved on the outer sides of the movable sampling arc plate 7 and the fixed sampling arc plate 13, and the inner side of the regulating ring 6 is connected to both ends of the steel wire 16.

[0025] Manually push the control handle 4 downward, and the control handle 4 drives the fixed column 5 to move downward together. At this time, the fixed column 5 pulls the connecting column 93 in the connecting assembly 9 and the second connecting tube 92 to move downward. At this time, the slider outside the connecting column 93 slides in the slide groove in the second connecting tube 92, and the slider outside the second connecting tube 92 slides in the slide groove in the first connecting tube 91. The fixed column 5 drives the mobile sampling arc plate 7, the fixed sampling arc plate 13 and the bottom ring 8 to move downward together through the connecting head 14. At the same time, start the motor 3, and the motor 3 drives the fixed column 5 and the connecting head 14 to rotate together through the connecting assembly 9, so that the mobile sampling arc plate 7 and the fixed sampling arc plate 13 rotate and move downward while being inserted into the harder or dense soil. The first threaded rod 15 is manually rotated, and the first threaded rod 15 rotates to drive the regulating ring 6 connected with the outer thread to move upward, and then the regulating ring 6 pulls the two ends of the steel wire 16 upward, so that the steel wire 16 in the accommodating groove 81 cuts the soil in the bottom ring 8, and at the same time, after the steel wire 16 in the accommodating groove 81 is pulled, the elastic rubber membrane 82 is pulled, so that the elastic rubber membrane 82 drags the soil above to prevent the soil from falling, so it can meet different usage requirements, and at the same time, through the setting of the circular groove 171, it will not affect the rotation of the later moving ring 12, thereby completing a series of tasks.
