Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a sampling cylinder for polluted soil. Background Technique

[0002] Soil sampling refers to the method of collecting soil samples, including the layout of sampling and sampling techniques. When collecting soil samples from a profile, it should be carried out after the profile observation and record are completed. Before sampling, the profile should be renovated, cleaned, and the top layer of floating soil should be removed. Then, samples should be taken layer by layer from the central typical part from top to bottom. However, after the existing soil pollution sampling cylinder samples the soil, since the soil is in the sampling cylinder, the user needs to use other tools to take it out. Moreover, the soil is relatively tightly squeezed in the sampling cylinder, which is not conducive to the user taking out the soil inside. At the same time, the lengths of most existing soil samplers are fixed. If the length is too short, people need to bend down or squat during use, which will cause serious physical fatigue after a long time and is not conducive to outdoor sampling work. If the length is too long, although sampling is convenient, it is not convenient to carry. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0022] The embodiment of the present application provides a contaminated soil sampling cylinder. This contaminated soil sampling cylinder can realize that the sample soil inside the sampling cylinder can be pushed out through the pushing component, without borrowing tools for soil sampling, and using the principle of leverage to push out the soil, which is more time-saving, labor-saving, simple and fast, helps to improve the soil sampling efficiency, and is more convenient to use.

[0023] The following provides a detailed description of the contaminated soil sampling cylinder. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0024] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] Please refer to Figures 1-6 In this embodiment, a contaminated soil sampling cylinder is provided, including: a sampling cylinder 1, a sleeve 11 is fixedly connected to the top of the sampling cylinder 1, an extension rod 12 is slidably connected inside the sleeve 11, a handle 13 is fixedly connected to the top end of the extension rod 12, a soil pushing block 14 is slidably connected inside the sleeve 11, a fixed seat 15 is fixedly connected to a position near the top outside the sampling cylinder 1, a pushing component, the pushing component is arranged outside the sleeve 11 and is used to control the movement of the soil pushing block 14 to push out the soil sample inside the sampling cylinder 1, the pushing component includes: a fixing plate 2, a force applying rod 21, a pull ring 22, a transmission arm 23 and a pushing rod 24, an adjusting component, the adjusting component is arranged on the fixed seat 15 and is used to adjust the length of the extension rod 12, the adjusting component includes: a cavity 3, a fixing rod 31, a fixing hole 32, a limiting plate 33 and a handle 34.

[0027] During use, the length of the extension rod 12 will be adjusted through the adjusting component, and the extension rod 12 will be pulled out from inside the sleeve 11, so as to extend the length without bending down or squatting for operation. Then, the bottom section of the sleeve 11 is inserted into the soil, and both hands hold the handle 34 and press down and rotate to make the sampling cylinder 1 penetrate deeper into the soil layer. Then, the sampling cylinder 1 is pulled out from the soil layer, and the sample soil is stored inside the sampling cylinder 1. Then, the pushing component is used to push the soil pushing block 14 downward, so as to push out the sample soil inside the sampling cylinder 1, thereby completing the sampling of the soil.

[0028] Among them, two rubber hand guards are sleeved outside the handle 13, and the two rubber hand guards are respectively arranged at both ends, and anti-slip patterns are provided on the outside of the two rubber hand guards. The rubber hand guards can protect the user's hands from abrasion, make the grasping more comfortable when used, the rubber hand guards have better friction to effectively avoid slipping off, and the setting of the anti-slip patterns further improves the friction, and there are gaps between the rubber hand guards and the hand skin so that air can circulate to reduce sweating.

[0029] Among them, a plurality of serrations are respectively arranged in an annular array at the bottom end of the sampling cylinder 1, and the inner cavity at the bottom end of the sampling cylinder 1 is designed in a frustum shape. The serrations at the bottom end of the sampling cylinder 1 can more easily penetrate into the soil layer and can cut the plant roots in the soil layer to avoid the plant roots blocking the sampling cylinder 1. The design of the bottom of the sampling cylinder 1 in a frustum shape can make the soil enter more smoothly and easily, and make the bottom end of the serrations become sharp.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, a cavity 3 that is respectively communicated with the inside and the outside of the sleeve 11 is provided inside the fixed seat 15. A fixed rod 31 is slidably connected inside the cavity 3. A series of a plurality of fixing holes 32 arranged at equal intervals are provided on the outside of the extension rod 12. One end of the extension rod 12 extends into one of the fixing holes 32, and the other end of the extension rod 12 extends to the outside and is fixedly connected with a limiting plate 33. A handle 34 is fixedly connected to one side of the limiting plate 33. A washer 35 is sleeved on the outside of the fixed rod 31. A force-applying plate 36 is fixedly connected to the outside of the fixed rod 31. A spring b 37 is connected between the force-applying plate 36 and the washer 35. The spring b 37 is sleeved on the outside of the fixed rod 31. The cavity inside the sleeve 11 and the extension rod 12 are both arranged in a hexagonal structure. One ends of the plurality of fixing holes 32 close to the fixed seat 15 are all arranged in a flared structure. One end of the fixed rod 31 close to the fixing hole 32 is arranged in an arc-shaped structure.

[0032] When it is necessary to adjust the length of the extension rod 12, first grasp the handle 34 and pull it to one side to separate the limiting plate 33 from one side of the fixed seat 15. The limiting plate 33 will drive the fixed rod 31 to slide inside the cavity 3. When moving, the force-applying plate 36 moves closer to the washer 35, thereby squeezing the spring b 37 therebetween. The spring b 37 is squeezed and contracts to store energy. One end of the fixed rod 31 withdraws from the fixing hole 32, thereby releasing the limitation on the extension rod 12. Subsequently, the extension rod 12 is pulled out or retracted from the inside of the sleeve 11 to adjust the length. The cavity inside the sleeve 11 and the extension rod 12 designed in a hexagonal structure enable the extension rod 12 to only move in the vertical direction and cannot rotate. After adjusting to the appropriate length, release the handle 34. The spring b 37 loses its restraint and releases its elasticity, pushing the force-applying plate 36 and the fixed rod 31 back to the initial position, causing the extension rod 12 to move into the sleeve 11. At this time, if one of the fixing holes 32 happens to be aligned with the fixed rod 31, the fixed rod 31 directly snaps into the fixing hole 32 to limit the extension rod 12. On the contrary, the fixed rod 31 abuts against the surface of the extension rod 12. The arc-shaped structure results in a small frictional force. At this time, slightly pull out or retract the extension rod 12 by a certain distance. The movement of the extension rod 12 aligns the fixing hole 32 with the fixed rod 31, and the fixed rod 31 is inserted into the fixing hole 32 for limitation. The fixing hole 32 arranged in a flared structure enables the fixed rod 31 to be more easily inserted into the fixing hole 32.

[0033] Embodiment 3

[0034] On the basis of Embodiment 1, two symmetrically arranged fixing plates 2 are fixedly connected to the outside of the sampling cylinder 1 near the middle position. One side of each of the two fixing plates 2 is rotatably connected to a force-applying rod 21. A pull ring 22 is fixedly connected between the bottoms of the two force-applying rods 21. One side of the tops of the two force-applying rods 21 near each other is rotatably connected to a transmission arm 23. One side of the bottoms of the two transmission arms 23 is rotatably connected to a push rod 24. Symmetrically arranged guide blocks 25 are fixedly connected to the outside of the earth-pushing block 14. Guide grooves 26 matching the two guide blocks 25 are formed in the outside of the sampling cylinder 1. One end of each of the two guide blocks 25 away from the center penetrates through the two guide grooves 26 and extends to the outside. The two push rods 24 are rotatably connected to the two guide blocks 25 respectively on the opposite sides.

[0035] When taking out the sample soil from the sampling cylinder 1, hold the pull ring 22 with the hand and pull it upward. The pull ring 22 drives the two force-applying rods 21 to move. The two force-applying rods 21 rotate and deflect with the connection point of the two fixing plates 2 as the center of the circle. At this time, the tops of the two force-applying rods 21 rotate to the lower side when rotating, and then drive the two transmission arms 23 to move downward. The two transmission arms 23 push the two push rods 24 to move. The two push rods 24 move downward to push the two guide blocks 25 to move in the two guide grooves 26. The earth-pushing block 14 is restricted by the guide blocks 25 and the guide grooves 26, so that the earth-pushing block 14 can only move along the guide grooves 26, thereby pushing out the sample soil in the sampling cylinder 1.

[0036] Wherein, a connection block a 27 corresponding to the two fixing plates 2 is fixedly connected to the outside of the sleeve 11 near the bottom position. Connection blocks b 28 are fixedly connected to one side of the backs of the two force-applying rods 21 respectively. A spring a 29 is connected between the connection block a 27 and the connection block b 28 on the same side.

[0037] When the two force-applying rods 21 rotate, they will drive the two connection blocks b 28 to move together. Since the bottom end of the spring a 29 is fixed by the connection block a 27, the movement of the connection block b 28 will pull the spring a 29 to extend. When the operation of pushing the soil is completed and the pull ring 22 is released, at this time the spring a 29 is released from restraint, and under the elastic action of the spring a 29, it drives the two force-applying rods 21 to rotate in the reverse direction and return to the initial position, so that the earth-pushing block 14 also returns to the initial position for convenient next soil sampling.

[0038] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0039] The above has introduced in detail a contaminated soil sampling cylinder provided by the embodiments of the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
