[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] As Figures 1 to 6 shown, the present invention provides a soil sampling device, including a housing 1. A sampling cylinder 5 is movably installed below the housing 1. A bottom ring block 6 is fixedly installed above the sampling cylinder 5. Elastic connection blocks 7 are evenly fixedly installed above the bottom ring block 6. A rubber ring 8 is fixedly installed above the elastic connection blocks 7. An outer ring block 9 located outside the bottom ring block 6 is fixedly installed above the sampling cylinder 5. A thread groove 10 is opened inside the outer ring block 9. A thread ring 11 is threadedly installed inside the thread groove 10. A snap ring 13 is fixedly installed below the thread ring 11.
[0023] When the sampling cylinder 5 needs to be replaced, only need to rotate the rotary knob 12 to drive the thread ring 11 to rotate. The thread ring 11 rotates and moves upward inside the thread groove 10, so that the thread ring 11 drives the snap ring 13 to move upward. The snap ring 13 moves upward and disengages from the rubber ring 8, causing the rubber ring 8 to release elastic potential energy and move outward, so that the rubber ring 8 disengages from the outer wall of the housing 1, and then the sampling cylinder 5 is taken out downward, thus completing the replacement of the sampling cylinder 5.
[0024] By rotating the rotary knob 12, the thread ring 11 drives the snap ring 13 to move upward and disengage from the rubber ring 8, so that the rubber ring 8 disengages from the outer wall of the housing 1, and then the sampling cylinder 5 is taken out downward, thus completing the replacement of the sampling cylinder 5. Compared with the traditional soil sampling device, this soil sampling device can complete the disassembly and installation of the sampling cylinder 5 by rotating the rotary knob 12, which is convenient for the staff to use.
[0025] Among them, an inclined surface cylinder 14 is fixedly installed inside the sampling cylinder 5. On both sides inside the sampling cylinder 5, a pressing plate 15 located above the inclined surface cylinder 14 is movably installed. An expansion spring 16 is elastically installed between the inner side of the sampling cylinder 5 and the inner side of the pressing plate 15. A connecting rod 17 extending into the sampling cylinder 5 is movably sleeved inside the housing 1. Below the connecting rod 17, a pushing plate 18 located below the housing 1 is fixedly installed. At the top of the connecting rod 17, a button 19 located above the circular plate 2 is fixedly installed.
[0026] When using this device for soil sampling, first place the sampling cylinder 5 above the ground, and insert the sampling cylinder 5 into the soil through the handle 3 and the foot pedal 4. The soil enters the inside of the sampling cylinder 5 through the inclined surface cylinder 14, causing the soil to press on the pressing plate 15, making the pressing plate 15 move inward to press the expansion spring 16, causing the expansion spring 16 to deform. Two triangular blocks are installed on both sides inside the sampling cylinder 5 and are convenient for being located on both sides of the pressing plate 15. When the pressing plate 15 slowly moves inward, one side of the pressing plate 15 closely adheres to the triangular block and moves inward. The soil is fixed by the pressing force of the pressing plate 15 on the soil to prevent the soil from falling.
[0027] By inserting the sampling cylinder 5 into the soil, the soil presses on the pressing plate 15. When the pressing plate 15 slowly moves inward, one side of the pressing plate 15 closely adheres to the triangular block and moves inward. The soil is fixed by the pressing force of the pressing plate 15 on the soil. Compared with traditional soil sampling devices, this soil sampling device fixes the soil through the pressing plate 15 to prevent the soil from falling off, which is convenient for the staff to use.
[0028] Among them, a reset spring 20 is elastically installed between the inner side of the button 19 and the upper side of the circular plate 2. The reset spring 20 is movably connected to the outside of the connecting rod 17.
[0029] Press the button 19 to make the button 19 move downward to press the reset spring 20, thereby driving the connecting rod 17 to move downward. The connecting rod 17 drives the pushing plate 18 to move downward to push out the soil.
[0030] Among them, handles 3 are fixedly installed on both sides at the top of the housing 1, and a foot pedal 4 is movably sleeved on the outside of the housing 1.
[0031] Insert the sampling cylinder 5 into the ground by pressing down the handle 3, and the staff can apply pressure to the sampling cylinder 5 better through the foot pedal 4.
[0032] Among them, a turning knob 12 is fixedly installed above the threaded ring 11. The turning knob 12 is located above the outer ring block 9.
[0033] Rotate the knob 12 so that the knob 12 drives the threaded ring 11 to rotate. The threaded ring 11 rotates upward inside the thread groove 10, causing the threaded ring 11 to drive the snap ring 13 upward.
[0034] Among them, the cross-section of the rubber ring 8 is triangular, and the cross-section of the snap ring 13 corresponds to the cross-section of the rubber ring 8.
[0035] The snap ring 13 moves upward and disengages from the rubber ring 8, causing the rubber ring 8 to release elastic potential energy and move outward, so that the rubber ring 8 disengages from the outer wall of the housing 1, and then the sampling cylinder 5 is taken out downward, thus completing the replacement of the sampling cylinder 5.
[0036] The working principle and usage process of the present utility model:
[0037] When the sampling cylinder 5 needs to be replaced, only need to rotate the knob 12 so that the knob 12 drives the threaded ring 11 to rotate. The threaded ring 11 rotates upward inside the thread groove 10, causing the threaded ring 11 to drive the snap ring 13 upward. The snap ring 13 moves upward and disengages from the rubber ring 8, causing the rubber ring 8 to release elastic potential energy and move outward, so that the rubber ring 8 disengages from the outer wall of the housing 1, and then the sampling cylinder 5 is taken out downward, thus completing the replacement of the sampling cylinder 5.
[0038] When using this device for soil sampling, first place the sampling cylinder 5 above the ground, and insert the sampling cylinder 5 into the soil through the handle 3 and the foot pedal 4. The soil enters the inside of the sampling cylinder 5 through the inclined cylinder 14, causing the soil to squeeze the extrusion plate 15, making the extrusion plate 15 move inward to squeeze the telescopic spring 16, deforming the telescopic spring 16. Two triangular blocks are installed on both sides inside the sampling cylinder 5 and are located on both sides of the extrusion plate 15. When the extrusion plate 15 slowly moves inward, one side of the extrusion plate 15 moves inward close to the triangular block, and the soil is fixed by the extrusion force of the extrusion plate 15 on the soil to prevent the soil from falling.
[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0040] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
