DETAILED DESCRIPTION
[0025] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the utility model.
[0026] See also Figures 1-6 As shown, this utility model is a soil sampling device for land management, comprising: a fixed tube 1, a vertical rod 123, a sampling assembly 12, a fixed block 11, a grip 131, a pressure handle 111, and a locking assembly. The sampling assembly 12 includes a sampling box 121, a tapered block 122, and a second threaded ring 212. The locking assembly includes a swivel 112, a first threaded ring 113, and a clamping block 114.
[0027] A fixed block 11 is fixedly connected to the top of the fixed cylinder 1, and a pressure handle 111 is fixedly connected to the left and right sides of the fixed block 11. A sampling assembly 12 is provided below the fixed cylinder 1. The sampling assembly 12 includes a sampling box 121, a conical block 122 is provided at the bottom of the sampling box 121, and a vertical rod 123 is provided at the center of the sampling box 121. By setting the sampling assembly 12, specifically by making the bottom of the conical block 122 contact with the soil, pressing the pressure handle 111, the conical block 122 drives the sampling box 121 and the fixed cylinder 1 into the soil. By different degrees of pressing, the sampling box 121 can be made to enter the soil at different depths, which is convenient for sampling different soils. To sample the soil at the same depth, rotate the swivel 112 counterclockwise to release the fixation of the vertical rod 123, and then drive the vertical rod 123 to do reciprocating motion upward and downward through the handle 131, and the sampling box 121 follows the movement, so that the soil can be collected quickly to complete the sampling. A swivel 112 is provided above the fixed block 11, and the internal thread of the swivel 112 is connected to the threaded ring 113, and the top of the threaded ring 113 is fixedly connected to the clamping block 114, the inner wall of the swivel 112 contacts the top of the clamping block 114, and the side of the clamping block 114 close to the vertical rod 123 contacts the outer surface of the vertical rod 123, and the bottom of the threaded ring 113 is fixedly connected to the top of the fixed block 11. After the sampling is completed, the sampling box 121 is pulled upward so that its top is tightly sealed against the bottom of the fixed tube 1, and then the swivel 112 is rotated clockwise. The swivel 112 is threadedly engaged with the threaded ring 113, and the threaded ring 113 is fixed, so that the swivel 112 moves downward, thereby squeezing the clamping block 114 downward and inward, so that the clamping block 114 is pressed against the vertical rod 123. The vertical rod 123 is fixed and can no longer move vertically relative to the fixed block 11. The bottom of the vertical rod 123 is connected to the sampling box 121, and the sampling box 121 is fixed. By fixing the sampling box 121, the sampling box 121 can be prevented from being pulled downward when pulled upward, thereby mixing soil of different depths, thereby ensuring the quality of sampling. A protective plate 13 is provided above the swivel 112, and a handle 131 is fixedly connected to the top of the protective plate 13. The top of the vertical rod 123 passes through the fixed block 11 and extends to be connected to the protective plate 13. A distance is maintained between the protective plate 13 and the fixed block 11. The swivel 112 and the threaded ring 113 are arranged between the protective plate 13 and the fixed block 11. The protective plate 13 is used to protect the hands of the staff to prevent their hands from being squeezed.
[0028] The top of the sampling box 121 is open, allowing soil to enter through the top. Multiple support blocks 211 are fixedly connected to the inner wall of the sampling box 121. These support blocks 211 are evenly arranged along the circumference of the vertical rod 123. The bottom of the vertical rod 123 extends into the sampling box 121, but maintains a distance from the bottom of the sampling box 121. One end of the support block 211 is fixed to the vertical rod 123, and the other end is fixed to the inner wall of the sampling box 121. The support blocks 211 enhance the structural strength of the sampling box 121.
[0029] The bottom of the sampling box 121 is fixedly connected to a second threaded ring 212. The second threaded ring 212 is a circular tube with external threads on its outer wall. The second threaded ring 212 is connected to the bottom of the sampling box 121. The external threads of the second threaded ring 212 are connected to a tapered block 122. The bottom of the tapered block 122 has a pointed cone structure. This pointed cone structure facilitates the insertion of the sampling device into the soil. The tapered block 122 seals the bottom of the second threaded ring 212, preventing the soil inside the sampling box 121 from falling out. By rotating the tapered block 122 counterclockwise to remove it from the bottom of the sampling box 121, the sampled soil will be discharged from the bottom of the sampling box 121 through the second threaded ring 212, making it easier to remove the sampled soil.
[0030] A fixing ring 231 is fixedly connected to the outer surface of the vertical rod 123. The fixing ring 231 is located within the fixed cylinder 1. The outer wall of the fixing ring 231 contacts the inner wall of the fixed cylinder 1, which is used to guide the vertical rod 123 to move vertically along the fixed cylinder 1. A spring 233 is fixedly connected to the top of the fixing ring 231. The top of the spring 233 is fixedly connected to the bottom of the fixed block 11 extending into the fixed cylinder 1. When the vertical rod 123 moves downward, the fixing ring 231 drives the spring 233 to stretch, which can assist the vertical rod 123 in returning to its original position upward through the action of the elastic force.
[0031] The inner wall of the fixed tube 1 is fixedly connected to a limit ring 14, which is located below the fixed ring 231, and a distance is maintained between the two. The bottom of the fixed ring 231 is fixedly connected to a limit rod 232, which extends downward through the limit ring 14 and is vertically movably connected to the limit ring 14, that is, it slides vertically. The limit rod 232 is parallel to the vertical rod 123. The vertical rod 123 is respectively connected to the fixed tube 1, the fixed block 11 and the limit ring 14 in a vertically movably manner. When the vertical rod 123 moves vertically, it will drive the limit rod 232 to slide within the limit ring 14 through the fixed ring 231, which is used to improve the stability of the vertical rod 123 and prevent shaking. At the same time, it can also limit the downward movement of the vertical rod 123. When the spring 233 is in its natural state, the distance between the limit ring 14 and the fixed ring 231 is the distance between the top of the sampling box 121 and the bottom of the fixed tube 1. This distance is greater than or equal to 5 cm.
[0032] A specific application of this embodiment is:
[0033] When in use, the spring 233 is in a contracted state. At this time, the top of the sampling box 121 contacts the bottom of the fixed tube 1, and the rotating ring 112 is rotated clockwise to make it move downward on the threaded ring 113, thereby squeezing the clamping block 114. The clamping block 114 is tightly attached to the vertical rod 123, and the vertical rod 123 is fixed, so that the sampling box 121 is fixed. Then the bottom of the conical block 122 contacts the soil, and the pressing handle 111 is pressed to make the conical block 122 drive the sampling box 121 and the fixed tube 1 into the soil. By different degrees of pressing, the sampling box 121 can be 121 enters the soil at different depths, which is convenient for sampling soil at different depths. After reaching the required depth, the rotating ring 112 is rotated counterclockwise to keep it away from the clamping block 114, and the vertical rod 123 is unfixed. Then, the vertical rod 123 is driven to move up and down by the handle 131. The protective plate 13 is used to protect the hands of the staff to prevent the hands from being squeezed. The vertical rod 123 drives the sampling box 121 to move together through the support block 211. When the vertical rod 123 moves downward, it drives the fixing ring 231 and the limit rod 2 When the sampling box 121 moves downward, the distance between the top of the sampling box 121 and the fixed cylinder 1 increases, and the soil will fall into the sampling box 121 for collection. The sampling box 121 can quickly collect soil by reciprocating up and down. Finally, after the collection is completed, the sampling box 121 is pulled upward to pull the vertical rod 123 so that the top of the sampling box 121 is The bottom of the fixed tube 1 is pressed tightly, and the top of the sampling box 121 is sealed. Then, the rotating ring 112 is rotated clockwise to fix the vertical rod 123, and the sampling box 121 is fixed. By fixing the sampling box 121, the sampling box 121 can be prevented from being pulled downward when pulled upward, thereby mixing soils of different depths, thereby ensuring the quality of sampling. Pull the pressure handle 111 to pull the device upward and take it out. After taking it out, rotate the conical block 122 counterclockwise to disassemble it. The sampled soil will be discharged from the bottom of the sampling box 121, making it easy to take out the sampled soil.
