Description

Technical Field

[0001] The invention relates to the technical field of wetland ecological restoration, and in particular to a soil sampling device for wetland ecological restoration. Background Art

[0002] Wetland restoration, also known as wetland remediation, refers to the repair or reconstruction of degraded or disappeared wetlands through ecological technology or ecological engineering, reproducing the structure and function of disturbed soil, as well as related physical, chemical and biological characteristics, so that it can play its due role. In the process of wetland ecological restoration, the soil condition of the wetland has a direct impact. If the wetland soil is not suitable for planting vegetation, the wetland ecology cannot be restored. Therefore, it is particularly important to detect the condition of the wetland soil. Therefore, it is necessary to sample the wetland soil and test the obtained soil to determine whether the soil is suitable for vegetation planting, and thus determine whether the wetland soil needs to be restored.

[0003] Sampling the wetland soil requires the use of a soil sampling device to sample the wetland soil. The drill rod is driven to rotate by a driving system to sample the wetland soil. When the above-mentioned soil sampling device samples the wetland soil, the soil drilled by the drill rod is discharged through the sampling holes on the soil, but the discharged sampled soil is mixed together. When soils at different depths are mixed, the moisture content of the soil at different depths is different. Therefore, soils at different depths are mixed together, which will affect the soil detection results, resulting in inaccurate sample detection results. Based on the above problems, the present application proposes a soil sampling device for wetland ecological restoration. Summary of the invention

At this time, the rotating shaft 35 drives the circular gear sleeve 21 to rotate through the connecting slide groove and the limiting protrusion, and drives the installation sleeve 22 and the circular gear plate 20 to rotate through the circular gear sleeve 21, and the installation sleeve 22 drives the rotating wheel 23 to rotate on the surface of the installation rod 24. At the same time, the circular gear plate 20 drives the rotating plate 19 to rotate, and drives the discharging circular pipe 18 to rotate through the rotating plate 19, so as to facilitate the adjustment of the slot position of the discharging circular pipe 18. Among them, the soil that does not need to be collected enters the left side of the discharging box 37 through the slot and is discharged, and the soil that needs to be collected enters the right side of the discharging box 37 and is discharged.To avoid the soil of different depths being mixed together and affecting the subsequent detection results, the telescopic component includes a spring 2 30 fixedly installed at the bottom of the moving plate 8, a mounting ring 29 fixedly arranged at the bottom of the spring 2 30, a moving tube 28 fixedly arranged inside the mounting ring 29, a connecting tube 31 slidingly arranged inside the moving tube 28, and a connecting tube 31 fixedly installed at the bottom of the discharge box 37. The moving tube 28 contacts the bottom, so that the soil pushes the moving tube 28 and the connecting tube 31 to move relative to each other, so that the mounting ring 29 compresses the spring 2 30, so that the connecting tube 31 shrinks to the inside of the moving tube 28, so that the sum of the moving tube 28 and the connecting tube 31 meets the length required for the drill rod 38 to transport the soil, so that it is convenient to adjust the distance between the moving tube 28 and the connecting tube 31 according to the depth of the drill rod 38 inserted into the soil.

[0029] Specifically, the lifting assembly includes a servo motor 2 fixedly installed on the top of the mounting frame 1, a double-groove transmission wheel 3 is fixedly provided at the output end of the servo motor 2, a transmission belt 4 is meshed on the surface of the double-groove transmission wheel 3, a single-groove transmission wheel 5 is meshed inside the transmission belt 4, the single-groove transmission wheel 5 is rotatably arranged inside the mounting frame 1, a rotating screw 6 is fixedly arranged inside the single-groove transmission wheel 5, a threaded sleeve 7 is threadedly arranged on the surface of the rotating screw 6, and the threaded sleeve 7 is fixedly installed inside the moving plate 8. The servo motor 2 drives the rotating screw 6 to rotate inside the mounting frame 1 through the double-groove transmission wheel 3, the transmission belt 4 and the single-groove transmission wheel 5, so that the threaded sleeve 7 drives the moving plate 8 to move downward, and the moving plate 8 drives the driving motor 15 to move downward through the mounting frame 14, so that the rotating shaft 35 drives the drill rod 38 to move downward, thereby facilitating the drill rod 38 to sample the soil.

[0030] Specifically, the moving distance detection component includes a fixed plate 9 fixedly installed on the top of the moving plate 8, a mounting vertical plate 10 is fixedly arranged on the top of the fixed plate 9, a measuring plate 11 is fixedly arranged on the top of the mounting vertical plate 10, a fixing seat 13 is arranged above the measuring plate 11, and a laser distance measuring sensor 12 is fixedly arranged on the right side of the fixing seat 13. The laser distance measuring sensor 12 is fixedly installed on the upper side wall of the mounting frame 1. When the moving plate 8 moves, the moving plate 8 will drive the fixed plate 9 to move downward, so that the fixed plate 9 drives the measuring plate 11 to move downward through the mounting vertical plate 10, and detects the distance between it and the measuring plate 11 through the laser distance measuring sensor 12. This distance is the depth of the drill rod 38 inserted into the soil, so that the sampling depth of the drill rod 38 in the soil can be determined, and the soil of the specified depth can be accurately sampled, avoiding the mixing of a large amount of soil of other depths in the sampled soil, thereby making the sampled soil purer, and making the sample inspection result more accurate.

[0031] Specifically, a self-locking universal wheel 32 is fixedly provided at the bottom of the mounting frame 1, a push handle 33 is fixedly provided on the surface of the mounting frame 1, and an anti-slip cover 34 is fixedly provided on the surface of the push handle 33. When the position of the sampling device needs to be moved, the staff holds the anti-slip cover 34 and pushes the mounting frame 1 to move through the push handle 33, so that the double-groove transmission wheel 3 drives the self-locking universal wheel 32 to roll, thereby moving the sampling device, so that the sampling device can sample different positions. After moving to the sampling position, the position of the mounting frame 1 is locked by the self-locking function of the self-locking universal wheel 32, thereby avoiding the deviation of the sampling device during the sampling process.

[0032] When in use: the output end of the driving motor 15 drives the drill rod 38 to rotate through the rotating shaft 35, and then drives the output end of the servo motor 2 to drive the double-groove transmission wheel 3 to rotate, the double-groove transmission wheel 3 drives the single-groove transmission wheel 5 to rotate through the transmission belt 4, and the rotating screw 6 is driven to rotate inside the installation frame 1 through the single-groove transmission wheel 5, so that the screw sleeve 7 drives the movable plate 8 to move downward, and drives the mounting frame 14 to move downward through the movable plate 8, so that the mounting frame 14 drives the driving motor 15 to move downward, and the driving motor 15 drives the drill rod 38 to move downward through the rotating shaft 35, so that the drill rod 38 contacts the soil and the drill rod 38 is inserted into the soil, and the movable tube 28 contacts the bottom, so that the soil pushes the movable tube 28 and the connecting tube 31 to move relative to each other, so that the movable tube 28 and the connecting tube 31 are moved relative to each other. The tube 28 compresses the spring 2 30 through the mounting ring 29, so that the connecting tube 31 shrinks to the inside of the moving tube 28, and the soil taken out by the drill rod 38 enters the inside of the connecting tube 31 through the moving tube 28, and enters the inside of the discharge circular tube 18 through the connecting tube 31, and enters the inside of the discharge box 37 through the notch on the right side of the discharge circular tube 18, and is discharged through the discharge port on the left side of the discharge box 37, and the upper layer of soil that does not need to be sampled is discharged. When the drill rod 38 reaches the sampling position and the drill rod 38 has completed discharging the previously drilled soil, the current of the annular electromagnet 36 is reduced, and the connection plate 26 is pushed downward by the rebound effect of the spring 1 27, so that the connection plate 26 drives the adsorption block 25 to move downward, and the adsorption block 25 drives the rotating wheel 23 through the mounting rod 24. The circular toothed plate 20 is moved downward, so that the rotating wheel 23 drives the installation sleeve 22 to move downward, and the installation sleeve 22 pushes the circular toothed sleeve 21 to insert into the surface of the circular toothed plate 20. At this time, the driving motor 15 drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the circular toothed sleeve 21 to rotate through the connecting groove and the limiting protrusion, and drives the installation sleeve 22 and the circular toothed plate 20 to rotate through the circular toothed sleeve 21, and the installation sleeve 22 drives the rotating wheel 23 to rotate on the surface of the installation rod 24. At the same time, the circular toothed plate 20 drives the rotating plate 19 to rotate, and drives the discharging circular tube 18 to rotate through the rotating plate 19, and limits the discharging circular tube 18 through the limiting plate 16 and the limiting ring 17, so that the notch of the discharging circular tube 18 rotates to the right. After the rotation is completed, the current of the annular electromagnet 36 is increased, so that the annular electromagnet 36 6 pairs of rotating shafts 35 are adsorbed, so that the rotating shaft 35 contacts the annular electromagnet 36, and the adsorption block 25 drives the connecting plate 26 to compress the spring 1 27, and the adsorption block 25 drives the rotating wheel 23 to move upward through the mounting rod 24, and the rotating wheel 23 drives the circular gear sleeve 21 to separate from the circular gear plate 20 through the mounting sleeve 22, then the rotating shaft 35 will not drive the discharge tube 18 to rotate, so that the notch of the discharge tube 18 is always facing the right side. In this process, the drill rod 38 no longer moves downward. After the adjustment is completed, the soil is drilled by the drill rod 38, and the drilled soil enters the inside of the discharge tube 18, and is discharged to the right side of the discharge box 37 through the notch of the discharge tube 18, and is discharged to the outside through the right side of the discharge box 37, and the discharged soil is collected.The specified depth can be sampled.
