DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0024] See also Figure 1 - Figure 6 As shown, a soil survey and sampling device based on erosion and accumulation landform basement includes a soil drilling machine 1, a sampler 20 and a pointed rod 22; the soil drilling machine 1 is fixed on a base plate 21, and four groups of support blocks 37 are welded and fixed at the bottom end of the base plate 21, and a supporting mechanism is arranged on the base plate 21, and the supporting mechanism includes a fixed shell 23, and a threaded rod 25 is rotatably connected inside the fixed shell 23, and threads with opposite rotation directions are provided on the left and right sides of the threaded rod 25, and moving blocks 26 are threadedly connected on the left and right sides of the threaded rod 25, and a clamping plate 27 is welded and fixed on the moving block 26, and the clamping plate 27 is slidably connected in a through groove 29, and the through groove 29 is provided at the rear end of the fixed shell 23, and the left side of the threaded rod 25 is fixed to the rotating shaft of the motor 24, and two groups of guide rods 30 are passed through the inside of the moving block 26, and the left and right sides of the guide rod 30 are both welded and fixed to the inner wall of the fixed shell 23;

[0025] When working, a geological survey sampling device in the above technology is used to sample the base soil on the eroded and deposited landforms. Since the soil of these landforms is generally loose and there may be mud or silt on the surface, it is difficult to fix the sampler. If the sampler is not fixed well, it is easy to tilt during the sampling process, which brings inconvenience. Through the structural design of the supporting mechanism, the function of supporting and fixing the sampler 20 when the soil drilling machine 1 is working is realized. When the soil drilling machine 1 pushes the sampler 20 to perform the sampling operation, first, when the motor 24 is driven, the threaded rod 25 rotating inside the fixed shell 23 is rotated. When the sampler 20 moves, the two groups of moving blocks 26 threadedly connected on the threaded rod 25 will move toward each other until the clamping plate 27 fixed on the moving block 26 contacts the surface of the sampler 20. At this time, the sampler 20 can be supported and fixed by the two groups of clamping plates 27 to ensure that the sampler 20 can move vertically downward to avoid the sampler 20 from tilting, thereby ensuring the stability of the sampler 20 during the sampling process. Two groups of guide rods 30 are passed through the moving block 26. The guide rods 30 are used to guide the movement of the moving block 26 on the threaded rod 25 to ensure the stable movement of the moving block 26. The through groove 29 is opened to ensure the normal movement of the clamping plate 27.

[0026] Furthermore, the pointed rod 22 is inserted on the bottom plate 21, and the top and bottom ends of the pointed rod 22 are respectively welded with a pressing block 31 and a first spring 35, and the bottom end of the first spring 35 is welded and fixed on the bottom plate 21;

[0027] When working, the diameter of the pressing block 31 is larger than the pointed rod 22, so as to increase the contact area, thereby better pushing the pointed rod 22 into the soil by pressing the pressing block 31. The first spring 35 is used to keep the position height of the pointed rod 22 fixed to ensure that the pointed rod 22 does not contact the ground when the pointed rod 22 is not in use.

[0028] Furthermore, four sets of fixing mechanisms are provided on the bottom plate 21, and the fixing mechanisms include a protrusion 38, the protrusion 38 is welded and fixed on the bottom plate 21, the inside of the protrusion 38 is slidably connected with a plug post 42, a second spring 44 is welded and fixed on the plug post 42, and the side of the second spring 44 away from the plug post 42 is welded and fixed to the inner wall of the protrusion 38, and two sets of slots 32 are opened on the pressing block 31;

[0029] During operation, the structural design of the fixing mechanism realizes the function of facilitating the fixing of the pointed rod 22, so that when the pointed rod 22 is inserted into the ground, the pointed rod 22 can be fixed by the abutment between the insertion column 42 and the slot 32, thereby preventing the pointed rod 22 from moving upward during the fixing process. After pressing the pressing block 31 downward and moving it to the lowest position, the pressing block 31 can be fixed by inserting the insertion column 42 into the slot 32.

[0030] Furthermore, a slider 43 is welded and fixed to the top of the plug post 42, and the slider 43 is slidably connected in the slide groove 39, and the slide groove 39 is provided on the protrusion 38;

[0031] During operation, the slider 43 is designed to release the engagement between the pin 42 and the slot 32. The pin 42 inside the protrusion 38 is moved by pushing the slider 43 until the pin 42 is no longer in contact with the slot 32. At this time, the pressing block 31 can be pulled out upward.

[0032] Furthermore, the surface of the pointed rod 22 is provided with a plurality of groups of long grooves 34, and the top of the pressing block 31 is provided with a groove;

[0033] During operation, the long groove 34 is used to increase the surface area of ​​the pointed rod 22 so that when the pointed rod 22 is inserted into the soil for fixation, there can be greater friction, which is convenient for fixing the pointed rod 22. A groove is provided on the top of the pressing block 31 to increase the surface area of ​​the pressing block 31 so as to facilitate pressing the pressing block 31.

[0034] Furthermore, a gasket 28 is glued and fixed on the clamping plate 27, and the gasket 28 is made of rubber;

[0035] During operation, the gasket 28 is made of rubber and fits with the clamping plate 27 to increase the friction between the clamping plate 27 and the sampler 20 , so that the clamping plate 27 has a better supporting and fixing effect on the sampler 20 .

[0036] Working principle: A geological survey sampling device in the prior art, when sampling the base soil on the eroded and deposited landforms, because the soil of these landforms is generally loose, and there may be mud or silt on the surface, the sampler is difficult to fix. If the sampler is not fixed well, it is easy to tilt during the sampling process, which brings inconvenience. In this case, a base soil survey sampling device based on eroded and deposited landforms is designed with a supporting mechanism to realize the function of supporting and fixing the sampler 20 when the soil drill 1 is working. When the soil drill 1 pushes the sampler 20 to perform the sampling operation, first, when the motor 24 is driven, the fixing shell 23 is When the internally rotating threaded rod 25 moves, the two groups of moving blocks 26 threadedly connected on the threaded rod 25 will move toward each other until the clamping plate 27 fixed on the moving block 26 contacts the surface of the sampler 20. At this time, the sampler 20 can be supported and fixed by the two groups of clamping plates 27 to ensure that the sampler 20 can move vertically downward to avoid the sampler 20 from tilting, thereby ensuring the stability of the sampler 20 during the sampling process. Two groups of guide rods 30 are passed through the moving block 26. The guide rods 30 are used to guide the movement of the moving block 26 on the threaded rod 25 to ensure the stable movement of the moving block 26. The through groove 29 is opened to ensure the normal movement of the clamping plate 27.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
