Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil environment detection device. Background Art

[0002] Soil is a complex multiphase system composed of three phases: solid, liquid and gas. The solid phase of soil includes minerals, organic matter and soil organisms; between the solid phase substances are pores of different shapes and sizes. There is water and air in the pores. Soil is mainly solid, and three phases coexist. The relative content of the three phases varies depending on the type of soil and environmental conditions. The three phases of matter are interconnected and restricted, and are connected to the atmosphere above and groundwater below, forming a complete multi-media and multi-interface system. The fertility of the soil is related to the mineral and organic matter components in the soil, and the diffusion of nutrients in the soil is related to the moisture of the soil.

[0003] At present, it is necessary to detect the moisture of the soil when detecting soil fertility. The existing detection method requires drilling a hole in the soil, and then extending the humidity detection sensor into the hole to detect the humidity at the depth of the soil.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7The present invention provides a technical solution: a soil environment detection device, comprising a guide column 1, an adjusting cavity 9 is provided inside the guide column 1 near the top edge, the top of the adjusting cavity 9 penetrates to the top of the guide column 1, a receiving cavity 18 is provided inside the guide column 1 near the bottom edge, the top of the receiving cavity 18 is connected to the bottom of the adjusting cavity 9, a plurality of strip grooves 3 are provided on the outer surface of the guide column 1 near the top edge along the circumferential direction at equal intervals, a driving member is provided inside the adjusting cavity 9, a positioning assembly is provided on the inner bottom surface of the adjusting cavity 9, and a supporting device is provided inside each of the plurality of strip grooves 3;

[0031] Two side frames 2 are fixed to the outer surface of the guide column 1 near the top edge, a plurality of openings 8 are evenly spaced near the edge of the inner bottom surface of the storage cavity 18, a guide cover 7 is fixed to the bottom of the guide column 1, a fixing sleeve 23 is fixed to the inner bottom surface of the storage cavity 18, a gap is left between the outer surface of the fixing sleeve 23 and the inner wall of the storage cavity 18, the bottom of the fixing sleeve 23 penetrates to the bottom of the guide column 1, a plurality of side openings 25 are evenly spaced near the bottom edge of the outer surface of the fixing sleeve 23, and a sponge ring 24 is provided on the outer surface of the fixing sleeve 23 The inner side of the sponge ring 24 extends from the side opening 25 to the inner wall of the fixed sleeve 23. A humidity sensor 22 is arranged between the inner walls of the fixed sleeve 23. A push rod 16 is fixed to the top of the humidity sensor 22. A fixing plate 19 is fixed to the outer surface of the push rod 16. The outer surface of the fixing plate 19 is in contact with the inner wall of the storage cavity 18. A plurality of connecting rods 21 are equidistantly fixed to the bottom of the fixing plate 19 near the edge of the outer surface. A pressing ring 20 is fixed between the bottoms of the plurality of connecting rods 21. The inner wall of the pressing ring 20 is in contact with the outer surface of the fixed sleeve 23.

[0032] The effect achieved is that, after a hole is opened in the soil and the guide column 1 is inserted into the hole, the humidity sensor 22 is pushed downward by the driving member, and in the process of the humidity sensor 22 extending outward, the soil hole wall is supported by the supporting device, thereby ensuring that the guide column 1 is located at the center of the hole, and avoiding the humidity sensor 22 from contacting the soil inside the aperture when extending. When the humidity sensor 22 is extended into place, the supporting device is positioned by the positioning assembly, thereby enhancing the stability of the supporting device and preventing loosening. When the humidity sensor 22 is extended outward, the push rod 16 slides downward, which drives the fixing plate 19 to slide downward, causing the pressure ring 20 to press the sponge ring 24 downward, thereby squeezing out the water flow inside the sponge ring 24 and keeping the sponge ring 24 in a compressed state. When the humidity sensor 22 is subsequently retracted, after the pressing force of the pressure ring 20 on the sponge ring 24 is released, the sponge ring 24 will expand and recover under the action of its own elastic force. At this time, when the humidity sensor 22 contracts toward the inside of the storage chamber 18, the sponge ring 24 can absorb the water flow on the outer surface of the humidity sensor 22.

[0033] like Figure 3 , Figure 4and Figure 5 As shown, the driving member includes an adjusting column 10, which is slidably connected between the inner walls of the adjusting cavity 9. A hexagonal groove 11 is provided on the top of the adjusting column 10, and a bottom groove 12 is provided on the bottom of the adjusting column 10. An annular groove 14 is provided on the outer surface of the adjusting column 10. A rotating block 13 is rotatably connected to the inner top surface of the bottom groove 12. The top of the push rod 16 is fixed to the bottom of the rotating block 13, and a spring 17 is fixed to the bottom of the rotating block 13. The bottom of the spring 17 is fixed to the inner bottom surface of the adjusting cavity 9. Z-shaped channels 29 are provided on the inner walls on both sides of the adjusting cavity 9, and the outer surfaces on both sides of the adjusting column 10 are correspondingly slidably engaged in the interior of the Z-shaped channels 29.

[0034] The effect achieved is that when the driving member is working, the external rod is engaged with the hexagonal groove 11 on the top of the adjusting column 10, and then the adjusting column 10 is pressed against the inner bottom surface of the adjusting cavity 9. During the pressing process, the raised parts on both sides of the adjusting column 10 slide inside the Z-shaped track 29, and the top edge of the annular groove 14 on the adjusting column 10 pushes the elastic paddle 28 to the outside of the guide column 1, thereby triggering the support device to work. When the adjusting column 10 is pressed to the inner bottom surface of the adjusting cavity 9, the friction ring 40 on the turntable 38 contacts the bottom of the adjusting column 10. At this time, the adjusting column 10 is rotated to make the raised parts on both sides of the adjusting column 10 rotate to the corner of the Z-shaped track 29, thereby limiting and fixing the adjusting column 10 through the corner of the Z-shaped track 29, and while rotating, it will also drive the turntable 38 to rotate, thereby driving the positioning component to work and locking the support device in position.

[0035] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the supporting device includes an arc-shaped plate 4, a supporting plate 5 is fixed to the outer surface of the arc-shaped plate 4, a positioning hole 6 is opened on the outer surface of the arc-shaped plate 4 near the bottom edge, the arc-shaped plate 4 is located inside the strip groove 3, and a groove 26 is opened on the inner bottom surface of the strip groove 3 near the top edge, a swing rod 15 is rotatably connected to the bottom of the arc-shaped plate 4 near the top edge, and the bottom end of the swing rod 15 is rotatably connected to the inside of the groove 26, a through-hole 27 is opened in the middle of the inner bottom surface of the strip groove 3, and the through-hole 27 penetrates into the inside of the adjustment cavity 9, and an elastic paddle 28 is arranged on the inner bottom surface of the through-hole 27, a slideway 33 is opened on one side of the arc-shaped plate 4, and a slider 34 is fixed on one side of the elastic paddle 28, The slider 34 is slidably engaged in the inside of the slideway 33, one side of the elastic paddle 28 extends to the inside of the adjustment chamber 9 and fits into the inside of the annular groove 14, a guide path 32 is provided inside the arc plate 4, the top of the guide path 32 passes through the bottom of the slideway 33, a reciprocating groove 30 is provided on one side of the support plate 5, one side of the reciprocating groove 30 extends obliquely to the inside of the guide path 32, a guide strip 35 is slidably provided inside the guide path 32, the top of the guide strip 35 is fixed on the slider 34, an insert plate 31 is slidably provided between the inner walls of the reciprocating groove 30, a nylon belt 36 is fixed to one end of the insert plate 31, one end of the nylon belt 36 extends to the inside of the guide path 32 and is fixed on the guide strip 35.

[0036] The effect achieved is that when the elastic paddle 28 is pushed toward the outside of the guide column 1, the arc plate 4 will be pushed toward the outside. In the process of pushing the arc plate 4 toward the outside, the top of the arc plate 4 is constrained by the swing rod 15, and the middle part of the arc plate 4 is constrained under the engagement of the slider 34 and the slideway 33. Therefore, when the arc plate 4 is pushed toward the outside, the swing rod 15 can be swung out from the inside of the groove 26 to support the arc plate 4. The pushing of the arc plate 4 toward the outside will simultaneously drive the support plate 5 to support the inner wall of the hole in the soil, thereby ensuring the stability of the guide column 1. When the arc plate 4 extends to a certain position toward the outside, the slider 34 slides downward inside the slideway 33, which will drive the nylon belt 36 to extend toward the inside of the reciprocating groove 30. When the nylon belt 36 extends into the inside of the reciprocating groove 30, it will push the plug plate 31 toward the outside, so that the plug plate 31 is inserted into the outside soil, thereby strengthening the positioning of the support plate 5.

[0037] like Figure 2 , Figure 3 and Figure 7As shown, the positioning assembly includes a turntable 38, which is rotatably engaged with the inner bottom surface of the adjustment cavity 9, a friction ring 40 is fixed to the top of the turntable 38 near the edge of the outer surface, a constraint groove 37 is provided near the bottom edge of the inner bottom surface of the strip groove 3, one end of the constraint groove 37 extends to the bottom of the turntable 38, the inner top surface of the constraint groove 37 near one side edge penetrates into the interior of the adjustment cavity 9, a positioning rod 42 is slidably provided inside the constraint groove 37, a lever 41 is fixed to the top of the positioning rod 42 near one end edge, a plurality of crescent grooves 39 are equidistantly provided on the top of the turntable 38 along the circumferential direction, the tops of the plurality of levers 41 extend to the interior of the crescent groove 39 correspondingly, and the outer surface of the lever 41 fits with the inner walls on both sides of the crescent groove 39.

[0038] The effect achieved is that when the adjusting column 10 is pressed to the inner bottom surface of the adjusting cavity 9, after the adjusting column 10 is rotated, the friction ring 40 located on the turntable 38 contacts with the bottom of the adjusting column 10, so the turntable 38 is driven to rotate. During the rotation of the turntable 38, the top of the lever 41 extends inside the crescent groove 39, and the outer surface of the lever 41 fits with the inner walls on both sides of the crescent groove 39, so the lever 41 can be driven to drive the positioning rod 42 to extend and retract. When the positioning rod 42 is extended and retracted outward, one end of the positioning rod 42 will extend to the inside of the positioning hole 6 on the arc plate 4, so that the arc plate 4 can be positioned.

[0039] Working principle: First, make a hole in the soil, then insert the guide column 1 into the hole, and then extend the humidity sensor 22 to detect the humidity at the depth of the soil. When extending, it is extended from the middle part of the hole so that it is not easy to contact with the soil, which can avoid the humidity sensor 22 from being contaminated. At the same time, when collecting, it can also avoid the humidity sensor 22 probe part contacting the soil pore side wall to cause bending and deformation. When the humidity sensor 22 is extended, it is first engaged with the hexagonal groove 11 on the top of the adjustment column 10 through the external rod, and then the adjustment column 10 is pressed against the inner bottom surface of the adjustment cavity 9. During the pressing process, the raised parts on both sides of the adjusting column 10 slide inside the Z-shaped track 29, and the top edge of the annular groove 14 on the adjusting column 10 pushes the elastic paddle 28 to the outside of the guide column 1, which pushes the arc plate 4 to the outside. In the process of pushing the arc plate 4 to the outside, the top of the arc plate 4 is constrained by the swing rod 15, and the middle part of the arc plate 4 is constrained under the engagement of the slider 34 and the slideway 33. Therefore, when the arc plate 4 is pushed outward, the swing rod 15 can swing out from the inside of the groove 26 to support the arc plate 4, and the arc plate 4 is pushed outward to synchronously bring The movable support plate 5 supports the inner wall of the hole in the soil, thereby ensuring the stability of the guide column 1. When the arc plate 4 extends to a certain position, the slider 34 slides downward inside the slideway 33, which drives the nylon belt 36 to extend into the reciprocating groove 30. When the nylon belt 36 extends into the reciprocating groove 30, it pushes the plug plate 31 outward so that the plug plate 31 is inserted into the soil outside, thereby strengthening the positioning of the support plate 5. When the adjusting column 10 is pressed to the inner bottom surface of the adjusting cavity 9, the friction ring 40 on the turntable 38 contacts the bottom of the adjusting column 10. At this time, the adjusting column 10 is rotated. The raised parts on both sides of the adjusting column 10 are rotated to the corners of the Z-shaped track 29, so that the adjusting column 10 is limited and fixed by the corners of the Z-shaped track 29, and the turntable 38 is also driven to rotate during the rotation. During the rotation of the turntable 38, the top of the lever 41 extends inside the crescent groove 39, and the outer surface of the lever 41 fits with the inner walls on both sides of the crescent groove 39. Therefore, the lever 41 can be driven to drive the positioning rod 42 to extend and retract. When the positioning rod 42 is extended and retracted outward, one end of the positioning rod 42 will extend to the inside of the positioning hole 6 on the arc plate 4, so that the arc plate 4 can be positioned.
