DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Example 1

[0031] In this embodiment, if Figure 1-Figure 8As shown, a soil sampling device with a light-shielding structure includes a base 101 and a sampling tube 102 arranged below the base 101, a support plate 103 is symmetrically arranged at the upper end of the base 101, a plurality of limit pins 104 are fixedly arranged at the lower end of the base 101, so that the limit pins 104 can be inserted into the ground, and a through hole 105 is opened in the middle of the base 101 to facilitate the up and down movement of the sampling tube 102 and the collar 203;

[0032] It also includes a light shielding mechanism 200 and an adjustment mechanism 300. The light shielding mechanism 200 is disposed between the two support plates 103 and is used to shield the sampling cylinder 102 from light. The adjustment mechanism 300 is disposed at the upper end of the sampling cylinder 102 and is used to drive the sampling cylinder 102 to perform a sampling operation.

[0033] The light-shielding mechanism 200 includes a slide groove 201 provided on the surface of the support plate 103, a slide plate 202 is slidably provided inside the slide groove 201, a collar 203 is fixedly provided at the lower end of the slide plate 202, and the collar 203 can be set to be a black or dark-colored opaque material, and the collar 203 is sleeved on the outer side of the sampling tube 102, which can effectively reduce the probability of the soil sample being photolyzed, and avoid the influence of external light on the temperature of the soil sample and the structural properties of the organic matter in the sample, thereby improving the accuracy of subsequent analysis, and a plurality of pointed plug blocks are fixedly connected to the bottom of the collar 203, so that the collar 203 can contact the ground to ensure the safety and stability of the device, and a guide rod 204 is fixedly provided inside one of the slide grooves 201, and the guide rod 204 and the slide The plate 202 is slidably connected to play a guiding role. A screw 205 is rotated inside the other slide groove 201. The screw 205 is threadedly connected to the slide plate 202. One end of the screw 205 extends to the outside of the support plate 103 and is fixedly connected to the handle. The handle is turned to drive the slide plate 202 and the ring 203 to move up and down. The ring 203 moves downward to shield the sampling tube 102 from light. The ring 203 moves upward to expose the sampling tube 102. When the soil sample needs to be transferred, the sampling tube 102 and the ring 203 are moved up. The sampling tube 102 is still inside the ring 203. A black rubber bag or other storage device is placed under the ring 203, so that it also has a light-shielding effect during the transfer process, thereby realizing an effective light-shielding operation on the soil.

[0034] Among them Figure 2-Figure 8As shown, the adjustment mechanism 300 includes a mounting plate 301 fixedly arranged on the top of the support plate 103, and a threaded sleeve 302 is rotatably arranged on the lower end of the mounting plate 301. One end of the threaded sleeve 302 extends to the outside of the mounting plate 301 and can be fixedly connected to the handle or the output end of the motor, so as to realize the rotation effect of the threaded sleeve 302, thereby realizing the up and down movement operation of the threaded rod 303. The slide plate 202 is sleeved on the outside of the threaded sleeve 302, and the threaded sleeve 302 is slidably connected to the slide plate 202. The internal thread of the threaded sleeve 302 is provided with a threaded rod 303. The threaded sleeve 302 rotates, thereby driving the threaded rod 303 to move up and down, so as to facilitate the adjustment of the position of the sampling tube 102 and facilitate the sampling operation of soil at different depths. The bottom of the threaded rod 303 is connected to the sampling tube 102 through a rotating assembly, so as to facilitate the rotation of the sampling tube 102, so that the sampling tube 102 is easier to be inserted into the soil.

[0035] Among them Figure 2-Figure 8 As shown, the rotating assembly includes a fixed block 304 fixedly connected to the bottom of the threaded rod 303, a first motor 305 is arranged inside the fixed block 304, an output end of the first motor 305 is fixedly connected to the top of the sampling barrel 102, the lower surface of the fixed block 304 is in contact with the upper surface of the sampling barrel 102, and the sampling barrel 102 is driven to rotate by the first motor 305. Both the first motor 305 and the second motor 310 are waterproof motors. An annular groove 306 is provided on the lower surface of the fixed block 304, and symmetrically arranged support rods are slidably connected inside the annular groove 306. The two support rods are fixedly arranged on both sides of the top of the sampling barrel 102 to increase the stability of the sampling barrel 102 when rotating. A switch assembly is also arranged inside the sampling barrel 102 to prevent soil from falling.

[0036] Among them Figure 5-Figure 8 As shown, the switch assembly includes a groove 307 arranged on the top wall of the sampling barrel 102. A depth sensor can be arranged on one side of the sampling barrel 102. The position of the depth sensor and the size of the sampling barrel 102 are fixed values, which is convenient for accurately calculating the depth during sampling. A movable block 308 is arranged inside the groove 307. A baffle 309 is fixedly installed at the lower end of the movable block 308. The baffle 309 is a semicircular structure. The baffle 309 is slidably connected to the inner wall of the sampling barrel 102. The top of the movable block 308 is fixedly connected to the output end of the second motor 310. The second motor 310 is fixedly arranged inside the sampling barrel 102. When no sampling operation is performed, the baffle 309 and the support plate 106 can be in an overlapping state. After the sampling operation is completed, the second motor 310 drives the movable block 308 to rotate half a circle, and the baffle 309 and the support plate 106 are in a non-overlapping state, thereby realizing the wrapping operation of the internal soil.

[0037] Among them Figure 5 and Figure 8As shown, a support plate 106 is fixedly provided at the bottom of the sampling barrel 102. The support plate 106 is a semicircular structure. The outer diameter of the support plate 106 is adapted to the outer diameter of the baffle 309, so that after reaching the designated position and completing the sampling operation, the support plate 106 can form a complete disc structure with the baffle 309, thereby wrapping the soil inside the sampling barrel 102 and effectively preventing the soil from falling from the inside of the sampling barrel 102.

[0038] Among them Figure 4 and Figure 6 As shown, the outer diameter of the collar 203 is smaller than the inner diameter of the through hole 105, and the outer diameter of the fixing block 304 is smaller than the inner diameter of the collar 203, so as to limit the size of the through hole 105 and the collar 203 and avoid interference.

[0039] Example 2

[0040] The difference from Example 1 is that Figure 1 As shown, an electric push rod 107 is fixedly provided on the top of the base 101 to facilitate the up and down movement of the probe of the soil moisture meter 109. The telescopic end of the electric push rod 107 is fixedly connected to the reinforcement block 108. The soil moisture meter 109 is fixedly installed on one side of the reinforcement block 108 to facilitate the detection and reading of the soil moisture inside the sampling area, so as to determine whether the area meets the sampling requirements.

[0041] Among them Figure 1 and Figure 2 As shown, a control panel and a power storage device are provided on one side of the base 101. The control panel, the power storage device and the electrical components are electrically connected to facilitate the control components to execute corresponding instructions.

[0042] When in use, the device is first placed on the soil surface where sampling is required, and then a number of limit pins 104 are inserted into the soil layer. The screw rod 205 is driven to rotate by turning the handle, and then the slide plate 202 and the ring 203 are driven to move downward, so that the pointed plug block is inserted into the soil layer to prevent the device from moving during sampling. The threaded sleeve 302 is rotated to drive the threaded rod 303 to move downward along the direction of the threaded sleeve 302, and then with the cooperation of the depth sensor, the sampling barrel 102 is moved to the corresponding position. The first motor 305 drives the sampling barrel 102 to rotate, so that the sampling barrel 102 is easier to insert into the soil of the corresponding depth. When the sampling is completed and needs to be taken out, the second motor 310 drives the movable block 308 to rotate, so that a sealing structure is formed inside the sampling barrel 102, which can effectively prevent the soil from falling.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
