Description

Technical Field

[0001] The utility model belongs to the technical field of soil collection, and particularly relates to a new type of precise soil sampler. Background Art

[0002] At present, in domestic geological surveys, cultivated land quality surveys, monitoring and evaluations, for soil collection, monitoring and scientific research in various regions, and timely grasping of the component changes of soil in various regions, it plays a very important role in preventing land pollution and protecting land resources in a timely manner. When sampling in a shallow soil layer, soil collection is convenient and accurate with relatively small errors. However, when the sampling depth is relatively deep (more than 20 cm), the conventional soil sampling device needs to collect soil every 20 cm and then collect the soil in the lower layer. The soil taken from the deep layer in the sampler is prone to mixing soils of different depths, resulting in poor soil representativeness and large errors in test results.

[0003] The existing soil sampler is not convenient for extracting soil samples. At the same time, there is no soil pushing component set. It needs to be dug with a screwdriver, or even if a pushing component is set, it is in the vertical direction directly above, which is more troublesome to use. Therefore, improvements are now made to a new type of precise soil sampler. Summary of the Utility Model

[0004] In order to overcome the above defects of the prior art, an embodiment of the utility model provides a new type of precise soil sampler, which can easily extract soil through the mutual cooperation between the collection component and the soil removal component, so as to solve the problems raised in the above background art.

[0005] To achieve the above object, the utility model provides a new type of precise soil sampler, which includes a piston cylinder. A soil pushing plate is movably sleeved inside the piston cylinder. A limiting ring is sleeved at the bottom of the piston cylinder, and a soil sampling cylinder is fixedly arranged at the bottom of the limiting ring. An L-shaped fixing plate is fixedly screwed on the outer surfaces of the limiting ring and the piston cylinder. A collection component is arranged at the top of the piston cylinder, and a soil removal component is arranged outside the collection component.

[0006] Preferably, the collection component includes a hollow rod fixedly installed at the center of the top of the piston cylinder. A pressure application rod is movably sleeved outside the hollow rod, and a handle is installed at the top of the pressure application rod.

[0007] Preferably, the soil removal assembly includes two rotating rods rotatably connected to the outside of the pressing rod. Connecting plates are rotatably connected to the outside of both rotating rods. One end of the connecting plate is rotatably connected to a second movable rod. A fixing rod is fixedly sleeved on the other end of the connecting plate. A fixing block is fixedly sleeved on the outside of the fixing rod. A pull rod is connected to the bottom of the fixing block. A rotating rod is rotatably connected to the outer surface of the second movable rod. One end of the rotating rod is rotatably connected to a first movable rod. A bearing seat is connected to the end of the first movable rod. A push rod is connected to the bottom of the bearing seat. The push rod penetrates through one side of the piston cylinder and is fixedly connected to the soil pushing plate.

[0008] Preferably, first guiding grooves and second guiding grooves are respectively formed on the opposite sides of the pressing rod and the hollow rod. The outside of the first movable rod is slidably connected to both the first guiding groove and the second guiding groove.

[0009] Preferably, a plurality of limiting blocks are arranged in an array on both sides of the outside of the hollow rod. A first limiting groove is arranged on the opposite side of the limiting block. The limiting block is rotatably connected to the first limiting groove. A second limiting groove is formed on the inner wall of the hollow rod. The second limiting groove is slidably connected to the limiting block.

[0010] Preferably, a top plate is fixedly sleeved on the bottom end of the pressing rod. A cushion plate is fixedly sleeved on the outside of the bottom end of the hollow rod. The top plate is located on top of the cushion plate.

[0011] Preferably, the push rod is movably sleeved inside the hollow rod.

[0012] 1. By rotating the pressing rod clockwise by half a turn, the limiting block outside the hollow rod is rotationally separated from the first limiting groove inside the pressing rod. During the rotational separation process, the limiting block vertically slides in the second limiting groove formed in the pressing rod. Then, the handle is used to repeatedly push and pull the pressing rod up and down, so that the top plate of the pressing rod contacts the cushion plate, and the soil sampling cylinder is driven into the soil. Immediately afterwards, the top plate is closely attached to the surface of the cushion plate, and by rotating the handle counterclockwise by half a turn, the handle drives the bottom pressing rod to rotate, so that the first limiting groove inside the pressing rod is rotationally contacted with the limiting block, and then the soil inside the soil sampling cylinder can be lifted out by the handle.

[0013] 2. By pulling up the pull rod, during this process, the fixing block drives the connecting plate on one side of the fixing rod to tilt upwards, thereby rotating the connecting plate through the rotating rod. Then, during the tilting process, the second movable rod pushes the bottom rotating rod. Further, during the pushing process of the rotating rod, the first movable rod at one end of the rotating rod drives the push rod at the bottom of the bearing seat to be pushed, so that the soil in the soil sampling cylinder is pushed through the connected soil pushing plate during the pushing process, thereby realizing the collection of soil. This soil sampler is simple to operate. Description of the Drawings

Detailed implementation manners

[0024] Such as Figure 2 and Figure 3As shown in the figure, an embodiment of the present utility model proposes a new type of precise soil sampler, which includes a piston cylinder 1. A soil pushing plate 23 is movably sleeved inside the piston cylinder 1. A limiting ring 2 is sleeved at the bottom of the piston cylinder 1. A soil sampling cylinder 4 is fixedly provided at the bottom of the limiting ring 2. The soil sampling cylinder 4 is made of stainless steel, which can prevent rust caused by residual moisture in the soil. The bottom of the soil sampling cylinder 4 is made into a blade shape, which should have a certain sharpness and strength to facilitate piercing into the deep soil. An L-shaped fixing plate 3 is fixedly threaded on the outer surfaces of the limiting ring 2 and the piston cylinder 1. A sampling assembly is provided at the top of the piston cylinder 1, and a soil removing assembly is provided outside the sampling assembly.

[0025] As Figure 1 and Figure 2 shown in the figure, the sampling assembly includes a hollow rod 24 fixedly installed at the center of the top of the piston cylinder 1. A pressure applying rod 21 is movably sleeved outside the hollow rod 24. A handle 25 is installed at the top of the pressure applying rod 21.

[0026] As Figure 3 and Figure 4 and Figure 6 shown in the figure, the soil removing assembly includes two rotating rods 17 rotatably connected to the outside of the pressure applying rod 21. Connecting plates 18 are rotatably connected to the outside of the two rotating rods 17. One end of the connecting plate 18 is rotatably connected to a second movable rod 13. A fixing rod 16 is fixedly sleeved at the other end of the connecting plate 18. A fixing block 15 is fixedly sleeved outside the fixing rod 16. A pull rod 6 is connected to the bottom of the fixing block 15. A rotating rod 12 is rotatably connected to the outer surface of the second movable rod 13. One end of the rotating rod 12 is rotatably connected to a first movable rod 11. The end of the first movable rod 11 is connected to a bearing seat 10. A pushing rod 9 is connected to the bottom of the bearing seat 10. The pushing rod 9 is movably sleeved inside the hollow rod 24. The pushing rod 9 penetrates through one side of the piston cylinder 1 and is fixedly connected to the soil pushing plate 23.

[0027] As Figures 5 to 7 shown in the figure, first guiding grooves 14 and second guiding grooves 19 are respectively formed on the opposite sides of the pressure applying rod 21 and the hollow rod 24. The outside of the first movable rod 11 is slidably connected to both the first guiding grooves 14 and the second guiding grooves 19. A plurality of limiting blocks 7 are arrayed on both sides of the outside of the hollow rod 24. A first limiting groove 8 is provided on the opposite side of the limiting blocks 7. The limiting blocks 7 are rotatably connected to the first limiting groove 8. A second limiting groove 20 is formed on the inner wall of the hollow rod 24. The second limiting groove 20 is slidably connected to the limiting blocks 7. Since the first limiting groove 8 inside the pressure applying rod 21 makes rotational contact with the limiting blocks 7 outside the hollow rod 24, the situation where the pressure applying rod 21 and the hollow rod 24 slide does not occur when the handle 25 lifts the soil sampling cylinder 4. At the same time, by rotating the handle 25 counterclockwise by half a turn, the handle 25 drives the pressure applying rod 21 at the bottom to rotate, so that the first limiting groove 8 inside the pressure applying rod 21 makes rotational contact with the limiting blocks 7. Thus, the soil inside the soil sampling cylinder 4 can be lifted out through the handle 25.

[0028] As Figure 4 and Figure 5 shown, a top plate 22 is fixedly sleeved at the bottom end of the pressure rod 21, and a cushion plate 5 is fixedly sleeved outside the bottom end of the hollow rod 24. The top plate 22 is located at the top of the cushion plate 5. By repeatedly pushing and pulling the pressure rod 21 up and down with the handle 25, the top plate 22 of the pressure rod 21 knocks on the piston cylinder 1, so that the soil sampling cylinder 4 at the bottom of the piston cylinder 1 is inserted into the soil, and when the top plate 22 contacts the cushion plate 5, it plays a role in protecting the piston cylinder 1.

[0029] Working principle:

[0030] When the sampler collects soil, first, according to the sampling depth, hold the handle 25 with both hands and insert the soil sampling cylinder 4 of this sampler into the soil. Then, rotate the pressure rod 21 clockwise by half a turn, so that the limit block 7 outside the hollow rod 24 rotates and separates from the first limit groove 8 inside the pressure rod 21. During the rotation and separation process, the limit block 7 vertically slides with the second limit groove 20 opened on the pressure rod 21. Then, repeatedly push and pull the pressure rod 21 up and down with the handle 25. During the pushing and pulling process, the top plate 22 at the bottom of the pressure rod 21 contacts the cushion plate 5, and the soil sampling cylinder 4 is driven into the soil. Immediately afterwards, keep the top plate 22 close to the surface of the cushion plate 5, and rotate the handle 25 counterclockwise by half a turn, so that the handle 25 drives the pressure rod 21 at the bottom to rotate, and the first limit groove 8 inside the pressure rod 21 rotates and contacts the limit block 7. Then, the soil inside the soil sampling cylinder 4 can be lifted out through the handle 25. Since the first limit groove 8 inside the pressure rod 21 rotates and contacts the limit block 7 outside the hollow rod 24, the situation that the pressure rod 21 and the hollow rod 24 slide during the process of the handle 25 lifting the soil sampling cylinder 4 will not occur. Then, move the sampler to the position for placing the soil. By pulling up the pull rod 6, the connecting plate 18 on one side of the fixed rod 16 is driven by the fixed block 15 to tilt upwards during this process, so as to rotate the connecting plate 18 through the rotating rod 17. Then, during the tilting process, the second movable rod 13 pushes the rotating rod 12 at the bottom. Then, during the pushing process of the rotating rod 12, the first movable rod 11 at one end of the rotating rod 12 drives the pushing rod 9 at the bottom of the bearing seat 10 to push, so that the soil in the soil sampling cylinder 4 is pushed through the connected soil pushing plate 23 during the pushing process, thus realizing the collection of the soil. This soil sampler is simple to operate and can accurately sample the soil.
