Description

Technical Field

[0001] The utility model relates to the technical field of biological crust sampling devices, in particular to a biological crust sampling component. Background Art

[0002] Biological crust, also known as biological soil crust or soil microbial crust, is a complex formed by microbacteria, fungi, algae, lichens and other cryptophytes and their hyphae, secretions, etc., bonded with soil gravel. It is an important type of surface cover in arid and semi-arid areas. In the soil crust related experiments, the sampled crust and the soil underneath it need to have a complete structure;

[0003] However, the current sampling device is more troublesome to use. It is usually necessary to dig a pit near the crust to be sampled and insert the sampling device into the pit to perform sampling. It is very inconvenient to use. During use, it is also necessary to constantly measure the depth of the pit, which is more troublesome.

[0004] For example, the publication number "CN215640239U" provides a complete sampler for biological crusts. The device pushes the sliding controller downward by moving the force nut downward, so that the collector and the sampling box move downward synchronously to complete the complete cutting and wrapping sampling of the biological crust soil sample. The bottom plate of the sampling box inserted into the bottom of the sample in advance contacts with the cut sampling box to complete the sealing. The principle is simple and reasonable, the practicability is strong, and the complete sampling can ensure the accuracy of the experimental research.

[0005] However, the above device still has the following problems during implementation:

[0006] However, when using the device, it is necessary to dig a hole on one side of the crust to be sampled in advance before using the sampling device, which is more troublesome to use. In addition, sandy soil is prone to collapse. Digging a hole on one side of the crust can easily cause the soil near the crust to collapse, causing the crust to be destroyed and affecting its use.

A pressure plate 15 is fixedly installed, including a connecting plate 1, characterized in that: a plurality of slide grooves are opened at the bottom of the connecting plate 1, and the connecting plate 1 is slidably connected to a sampling assembly 2 through the plurality of slide grooves. The sampling assembly 2 includes a first plug rod 21 and a second plug rod 22. The tops of the first plug rod 21 and the second plug rod 22 are fixedly installed with connecting columns 26, and the two connecting columns 26 are respectively slidably connected to adjacent slide grooves. The bottoms of the first plug rod 21 and the second plug rod 22 are fixedly installed with a first plug 24. The top of the connecting plate 1 is also fixedly installed with a connecting rod 14. A pressure plate 15 is fixedly installed on the top, and a measuring rod 4 is also provided at the bottom of the connecting plate 1. A fixing plate 25 is fixedly installed in the inner wall of the first plug rod 21 and the second plug rod 22. A connecting groove is provided in the two fixing plates 25. The two fixing plates 25 are connected to the sampling box 3 through the connecting groove. A socket 23 is provided on one end of the first plug rod 21 and the second plug rod 22 close to the first plug 24. The first plug rod 21 and the second plug rod 22 are slidably connected to a blocking plate through the socket 23. The top of the blocking plate abuts against the bottom of the sampling box 3.

The rotating gear 12 is rotatably connected to the connecting plate 1 at a side away from the driving motor 11. Adjustment racks 13 are arranged on both sides of the rotating gear 12. The two adjustment racks 13 are meshed with the rotating gear 12. The two connecting columns 26 at the top of the first plug rod 21 and the second plug rod 22 penetrate the bottom of the connecting plate 1 and extend to the inside of the connecting plate 1. The extended ends of the two connecting columns 26 are respectively fixed to the bottoms of the two adjustment racks 13;

[0032] When the device is to be used, the driving motor 11 is first started, so that the driving motor 11 drives the rotating gear 12 to rotate, and the rotating gear 12 drives the two adjusting racks 13 to move away from each other, so that the two adjusting racks 13 respectively drive the first plug rod 21 and the second plug rod 22 to move away from each other through the connecting column 26, so that the distance between the first plug rod 21 and the second plug rod 22 is increased, and the sampling box 3 is installed in the first plug rod 21 and the second plug rod 22 through the fixing plate 25 provided in the first plug rod 21 and the second plug rod 22;

[0033] After installation, hold the pressing plate 15, align the first plug 24 with the area where sampling is required, press the pressing plate 15 downward, so that the pressing plate 15 drives the sampling assembly 2 to be inserted downward through the connecting rod 14 and the connecting plate 1, and observe the insertion depth through the measuring rod 4. When the depth is appropriate, start the driving motor 11 again, so that the rotating gear 12 drives the two adjusting racks 13 to move in a direction close to each other, so that the first plug rod 21 and the second plug rod 22 are close to each other, until the first plug rod 21 fits with the second plug rod 22;

[0034] Pull out the sampling assembly 2 upwards, insert the sealing plate of the sampling box 3 into the bottom of the sampling box 3 through the socket 23, lay the sampling assembly 2 flat on the ground, start the driving motor 11 again, so that the rotating gear 12 drives the adjusting rack 13 to move outward, so that the first plug rod 21 and the second plug rod 22 are continuously opened. During the opening process of the first plug rod 21 and the second plug rod 22, the sampling box 3 gradually separates from the fixing plate 25, and the sampling box 3 is held to take out the sampling box 3 from between the first plug rod 21 and the second plug rod 22.

[0035] For example 2, please refer to Figure 1 , Figure 2 and Figure 3 The sampling box 3 includes a first storage box 31 and a second storage box 32. The first storage box 31 and the second storage box 32 are respectively arranged in the first plug rod 21 and the second plug rod 22. The tops of the first storage box 31 and the second storage box 32 are both clamped with a closed cover 33. The tops of the two closed covers 33 are fixedly installed with a plurality of connecting blocks 36. The first storage box 31 and the second storage box 32 are connected to the two fixed plates 25 through the plurality of connecting blocks 36. The closed cover 33 on the first storage box 31 is provided with a plurality of clamping holes 34 on one side close to the second storage box 32. Two clamping blocks 35 with the same positions as the clamping holes 34 are fixedly installed on the other closed cover 33. The two clamping blocks 35 are respectively clamped in the adjacent clamping holes 34.

[0036] When in use, firstly, the sampling box 3 is fixed to the sampling assembly 2 through the connection block 36 provided on the top of the first storage box 31 and the second storage box 32, and the plurality of connection blocks 36 are respectively inserted into the adjacent connection grooves to fix the sampling box 3. When sampling, when the first insertion rod 21 and the second insertion rod 22 are close to each other to surround the sampled soil, the clamping block 35 provided on the second storage box 32 gradually approaches the clamping hole 34 provided on the first storage box 31. When the first insertion rod 21 and the second insertion rod 22 are completely closed, the clamping block 35 is simultaneously inserted into the clamping hole 34 and clamped in the clamping hole 34 to be fixed;

[0037] When sampling is completed, the first plug rod 21 is separated from the second plug rod 22 by starting the driving motor 11. Under the action of the snap-in hole 34 and the snap-in block 35, the first storage box 31 and the second storage box 32 are always kept closed. During the continuous outward movement of the first plug rod 21 and the second plug rod 22, the connecting block 36 is gradually disengaged from the connecting groove, so that the sampling box 3 is separated from the sampling assembly 2.

[0038] For example 3, please refer to Figure 1 and Figure 5 The top of the measuring rod 4 is threadedly connected to the inside of the connecting plate 1, a moving ring 43 is slidably sleeved on the measuring rod 4, an adjusting bolt 45 is threadedly connected on the arc surface of the moving ring 43, an end of the adjusting bolt 45 close to the moving ring 43 passes through the moving ring 43 and abuts against the surface of the measuring rod 4, the moving ring 43 is fixed to the measuring rod 4 by the adjusting bolt 45, an adjusting plate 44 is also fixedly installed at the bottom of the moving ring 43, and a knob is fixedly connected to the end of the adjusting bolt 45 away from the moving ring 43, a scale line 41 is provided on the surface of the measuring rod 4, and a second plug 42 is also provided at the bottom of the measuring rod 4;

[0039] By means of the provided measuring rod 4 and scale lines 41, during use, the insertion depth can be observed through the scale lines 41, so as to facilitate the control of the sampling depth. By means of the provided moving ring 43 and adjusting plate 44, during use, the adjusting bolt 45 can be disengaged from the surface of the measuring rod 4 by turning the knob, so that the moving ring 43 can slide on the measuring rod 4, and the moving ring 43 drives the adjusting plate 44 to move simultaneously. After the adjusting plate 44 is moved to a suitable position, the knob is turned again so that the adjusting bolt 45 abuts against the measuring rod 4, so that the moving ring 43 and the adjusting plate 44 are fixed on the measuring rod 4. During sampling, when the sampling assembly 2 is inserted downward, the measuring rod 4 and the sampling assembly 2 are simultaneously inserted into the soil. When the adjusting plate 44 contacts the soil surface, it indicates that the appropriate depth has been inserted.

[0040] By setting the movable ring 43 and the adjusting plate 44, the insertion depth can be intuitively understood through the adjusting plate 44 during use. By adjusting the position of the adjusting plate 44, the sampling depth can be controlled through the adjusting plate 44 during sampling, which is convenient to use. By setting the threaded measuring rod 4, the measuring rod 4 can be disassembled after use, which is convenient to carry and use.

[0041] Working principle: When the device needs to be used, first start the driving motor 11, so that the driving motor 11 drives the rotating gear 12 to rotate, and the rotating gear 12 drives the two adjusting racks 13 to move in the direction away from each other, so that the two adjusting racks 13 respectively drive the first plug rod 21 and the second plug rod 22 to move in the direction away from each other through the connecting column 26, so that the distance between the first plug rod 21 and the second plug rod 22 is increased, and the sampling box 3 is installed in the first plug rod 21 and the second plug rod 22 through the fixing plate 25 provided in the first plug rod 21 and the second plug rod 22. After installation, turn the knob to disengage the adjusting bolt 45 from the surface of the measuring rod 4, so that the moving ring 43 drives the adjusting plate 44 to move at the same time. When the adjusting plate 44 is moved to a suitable position, turn the knob again to make the adjusting bolt 45 abut against the measuring rod 4, so that the moving ring 43 and the adjusting plate 44 are fixed on the measuring rod 4;

[0042] Hold the pressing plate 15 and press it downward, so that the pressing plate 15 drives the sampling assembly 2 to be inserted downward through the connecting rod 14 and the connecting plate 1. When the adjusting plate 44 contacts the ground, it means that the sampling assembly 2 has been inserted to a suitable sampling depth. Under the action of the adjusting plate 44, it cannot be inserted further downward. The driving motor 11 is started again, so that the rotating gear 12 drives the two adjusting racks 13 to move in a direction close to each other, so that the first insertion rod 21 and the second insertion rod 22 are close to each other and fit together. The clamping block 35 provided on the sampling box 3 is inserted into the clamping hole 34 at the same time, and is clamped and fixed in the clamping hole 34.

[0043] Pull out the sampling assembly 2 upward, insert the sealing plate of the sampling box 3 into the bottom of the sampling box 3 through the socket 23, lay the sampling assembly 2 flat on the ground, start the driving motor 11 to separate the first plug rod 21 from the second plug rod 22, and under the action of the snap-in hole 34 and the snap-in block 35, the first storage box 31 and the second storage box 32 are always kept closed. As the first plug rod 21 and the second plug rod 22 continue to move outward, the connecting block 36 is gradually disengaged from the connecting groove, so that the sampling box 3 is separated from the sampling assembly 2.
