[0002] Soil refers to a loose layer of material on the surface of the earth, composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. When conducting geological surveys, it is necessary to sample the surface soil. The current soil sampling method mostly uses a vertical tube or a soil sampling tube inserted into the soil on the ground to collect soil. The principle of soil sampling is that when the vertical tube or the soil sampling tube is pulled upward, it can bring out the soil squeezed into the tube.

[0003] However, soil generally has a certain viscosity. After the soil sampling tube is inserted into the soil and pulled out, it is not convenient to take out the sample from the vertical tube (sampling tube). Therefore, a surface soil sampling device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] Reference Figure 1-Figure 3 The utility model provides an embodiment of a surface soil sampling device, comprising a pressing handle 1, a pressing vertical rod 2 is connected to the bottom of the pressing handle 1, a pushing assembly 3 is sleeved on the outer surface of the pressing vertical rod 2, a pressing pedal 5 is fixed to the bottom end of the pressing vertical rod 2, a sampling tube 7 is arranged at the bottom of the pressing pedal 5, and the sampling tube 7 is divided into two parts, a horizontal pushing assembly 4 is arranged between the pushing assembly 3 and the pressing pedal 5, the horizontal pushing assembly 4 is connected to the two parts of the sampling tube 7, and is used to realize the opening and closing of the two parts of the sampling tube 7, and the horizontal pushing assembly 4 is connected to the sampling tube 7 by a quick disassembly assembly 8, and is used to quickly replace the sampling tube 7, and an anti-skid protrusion 6 is arranged on the upper surface of the pressing pedal 5, which plays an anti-skid role when the pressing pedal 5 is stepped on to press the sampling tube 7 into the soil.

[0029] The pushing assembly 3 includes a push plate 31 sleeved on the surface of the pressing vertical rod 2, the bottom end of the push plate 31 is connected to an extension sleeve 32, and the bottom end of the extension sleeve 32 is connected to a support plate 33, so as to facilitate pushing the push plate 31 downward.

[0030] The lateral pushing assembly 4 is divided into two groups, which are respectively arranged on both sides of the pressing vertical rod 2 and are evenly stressed. The lateral pushing assembly 4 includes a cross rod 42, and the top of the cross rod 42 is rotatably connected to two first sliders 41, and the bottom of the cross rod 42 is rotatably connected to two second sliders 43. The two first sliders 41 are slidably connected to the support plate 33, and the two second sliders 43 are slidably connected to the pressing plate 5. Therefore, when the angle of the cross rod 42 becomes larger, the two second sliders 43 will open, thereby driving the two parts of the sampling tube 7 to separate.

[0031] A guide rod 45 is fixed inside the pressing plate 5, and two second sliders 43 are respectively sleeved on the outer surfaces of the guide rod 45. A first spring 44 is connected between the two second sliders 43 and the inner wall of the pressing plate 5. The first spring 44 is sleeved on the outer surface of the guide rod 45. Under the action of the elastic force of the first spring 44, the two parts of the sampling tube 7 can be firmly closed together to facilitate sampling.

[0032] The quick disassembly assembly 8 includes a fixed block 81 fixed to the top of the sampling tube 7. A slot is provided at the bottom of the second sliding block 43. The fixed block 81 is inserted into the slot. A groove is provided on one side of the fixed block 81. A second spring 82 is fixed inside the groove. A clamping block 83 is fixed at one end of the second spring 82. The clamping block 83 is engaged with a clamping hole on the surface of the slot. Separation can be achieved by pressing the clamping block 83, retracting the clamping block 83, and pulling the fixed block 81 out of the slot.

[0033] Working principle: When in use, the device is turned vertically downward, and the handle 1 and the pressing pedal 5 are pressed downward to make the sampling tube 7 sink into the soil for sampling. After the sampling is completed, the sampling tube 7 is pulled out, and the push plate 31 is pushed downward by hand, so that the extension sleeve 32 drives the support plate 33 to move downward, thereby increasing the angle of the cross rod 42 and the distance between the two second sliders 43, so that the two parts of the sampling tube 7 can be opened, which is convenient for taking out the soil sample.

[0034] When the sampling tube 7 needs to be disassembled and replaced, the clamping block 83 is pressed to separate the clamping block 83 from the clamping hole, and the sampling tube 7 is pulled downward to remove it for replacement.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
