Description

[0002] Soil and water conservation refers to the prevention and control measures taken against soil erosion caused by natural factors and human activities. The main measures include engineering measures, biological measures and water storage and soil conservation farming measures. Engineering measures include slope control projects, such as various terraces, tablelands, horizontal ditches, fish scale pits, etc.; ditch control projects, such as silt dams, sand retaining dams, valley workshops, ditch head protection, etc.; small-scale water conservancy projects, such as pools, water cellars, drainage systems and irrigation systems; biological measures are soil and water conservation measures that adopt afforestation, grass planting and management methods to increase vegetation coverage, maintain and improve land productivity, mainly including afforestation, grass planting and closing mountains for afforestation and grass cultivation; If soil and water conservation is not in place, soil erosion will occur, that is, soil and water conservation monitoring is equivalent to soil and water loss monitoring.

[0003] The soil and water loss monitoring probe is a tool used to monitor soil and water loss in the entire process before, during and after the construction of a development and construction project.

[0044] See also Figure 1-7 The present invention provides a technical solution: a drilling device for soil and water conservation monitoring, comprising a ring-shaped support plate 11, two support columns 12 are arranged on the edge of the top surface of the support plate 11, and the planes where the two support columns 12 are located are perpendicular to the plane where the support plate 11 is located, and coincide with the axis of the support plate 11;

[0045] A plurality of support rods 13 are disposed between the two support columns 12, and the plurality of support rods 13 are perpendicular to the support columns 12 and are arranged in a linear array along the length direction of the support columns 12;

[0046] Both ends of the plurality of support rods 13 are respectively connected to the two support columns 12 by sliding along the length direction of the support columns 12, and the plurality of support rods 13 are provided with limiting holes 131 coaxial with the support plate 11;

[0047] An adjusting portion is provided between the plurality of support rods 13 and the support column 12 for driving the plurality of support rods 13 to gather downward or disperse upward.

[0048] By setting a support plate and using a support plate 11 to fit the ground, the support plate 11 is made to be parallel to the slope surface, so as to reduce the influence of the local unevenness of the ground on the insertion of the drill; the support column 12 is set vertically with the support plate, and a plurality of support rods 13 are arranged along the length direction on the support column 12, and a limit hole 131 coaxial with the support plate 11 is opened on the support rod 13, and the probe 34 is connected in series to the plurality of limit holes 131 on the plurality of support rods 13, so as to quickly adjust the probe 34 to be perpendicular to the slope surface, thereby reducing the difficulty of operation. At the same time, the plurality of support rods 13 provide lateral support to different positions in the middle of the probe 34, so as to reduce the risk of bending and deformation of the probe 34 during the knocking process. The support rod 13 is slidably connected to the support column 12, and the plurality of support rods 13 are driven to gather downward or disperse upward by the adjustment part, so as to adjust the height of the plurality of support rods 13 according to the length of the probe 34 and the depth of the probe 34 inserted into the soil, stably support the probe 34, and smoothly insert the probe 34 into the soil.

[0049] In this embodiment: two slide grooves 121 along the length direction of the support columns 12 are opened on the two facing sides of the two support columns 12, and the two ends of the support rod 13 are respectively inserted into the two slide grooves 121 and slide together with a single degree of freedom along the length direction of the support column 12.

[0050] The slide groove 121 is a T-shaped groove, and both ends of the support rod 13 are T-shaped blocks adapted to the T-shaped groove to limit the support rod 13 from rotating freely on the support column 12, so that the two support columns 12 support the support rod 13 laterally and stably.

[0051] In this embodiment: the adjusting part includes a screw rod 21 and a slide rod 22 which are arranged in the slide groove 121 and are parallel to the support column 12 respectively. The screw rod 21 is connected in series with a plurality of support rods 13, and the two ends are fixedly connected to the top wall and the bottom wall of the corresponding slide groove 121 respectively. The slide rod 22 is connected in series with a plurality of support rods 13, and the two ends are rotatably matched with the top wall and the bottom wall of the corresponding slide groove 121 respectively.

[0052] A plurality of transmission units corresponding to the plurality of support rods 13 are arranged between the screw rod 21 and the slide rod 22, and the transmission units include a first outer gear ring 23 and a second outer gear ring 24 meshing with each other, and the transmission ratios of the plurality of transmission units increase from bottom to top, and the transmission ratios of two adjacent transmission units differ by one time;

[0053] The first outer gear ring 23 is sleeved on the outside of the screw rod 21 and connected by threaded fitting, and the first outer gear ring 23 is rotatably connected to the corresponding support rod 13, the second outer gear ring 24 is sleeved on the outside of the sliding rod 22 and slidably fitted with a single degree of freedom along the length direction of the sliding rod 22, and the second outer gear ring 24 is rotatably connected to the corresponding support rod 13.

[0054] During use, the support plate 11 is placed stably on the slope surface at the position to be monitored, and the measuring rod 34 is held by hand to pass the sharp end of the measuring rod 34 through the multiple limiting holes 131 on the multiple support rods 13 in turn until the measuring rod 34 stands on the slope surface. When the measuring rod 34 is too long and multiple support rods 13 are all located at the bottom of the support rod 13, the slide bar 22 is rotated in the opposite direction, and the slide bar 22 drives the second outer gear ring 24 to rotate in the opposite direction, and the second outer gear ring 24 drives the first outer gear ring 23 to rotate in the opposite direction. The external thread on the screw rod 21 pushes the first outer gear ring 23 to move upward, that is, the second outer gear ring 24 drives the corresponding support rod 13 to move upward in the slide groove 121, and the second outer gear ring 24 rotates in the opposite direction while sliding upward on the slide bar 22 to raise the height of the support rod 13. At the same time, since the transmission ratios of the multiple transmission units increase from bottom to top, and the transmission ratios of two adjacent transmission units differ by one times, and the multiple support rods 13 are arranged in a linear array along the length direction of the support column 12, the distance between any two adjacent support rods 13 is the same. During the reverse rotation of the slide rod 22, the upward movement distance of the multiple support rods 13 increases from bottom to top, so that the distance between any two adjacent support rods 13 is always the same and continues to increase, and finally the multiple support rods 13 are dispersed, thereby dispersing the support points in the length direction of the measuring rod 34, further reducing the risk of bending and deformation of the measuring rod 34 during the striking process.

[0055] When the top end of the measuring rod 34 is close to the support rod 13 but needs to continue to be inserted downward into the soil, the slide rod 22 is rotated forward, the slide rod 22 drives the second outer gear ring 24 to rotate forward, the second outer gear ring 24 drives the first outer gear ring 23 to rotate forward, and the external thread on the screw rod 21 pushes the first outer gear ring 23 to move downward, that is, the second outer gear ring 24 drives the corresponding support rod 13 to move downward in the slide groove 121, and the second outer gear ring 24 rotates forward while sliding downward on the slide rod 22 to lower the height of the support rod 13 and provide necessary space for the measuring rod to move downward.

[0056] That is, when the slide bar 22 is rotated forward, the multiple support rods 13 move downward and gather together, providing necessary space for the measuring rod to move downward; when the slide bar 22 is rotated backward, the multiple support rods 13 move upward and disperse, dispersing the support points in the length direction of the measuring rod 34, further reducing the risk of bending and deformation of the measuring rod 34 during tapping.

[0057] In this embodiment: the number and specification of teeth of the first outer gear ring 23 on the plurality of transmission units are the same, and the first outer gear ring 23 is embedded in the support rod 13 and rotates in cooperation;

[0058] The second outer gear rings 24 on the plurality of transmission units have the same specifications, the number of teeth increases from bottom to top, and the number of teeth in two adjacent second outer gear rings 24 differs by one time. The second outer gear rings 24 are embedded in the support rod 13 and rotate in cooperation.

[0059] The structural parameters of the multiple first outer gear rings 23 on the multiple transmission units are completely the same, and the parameters such as the module, pitch circle diameter, and pressure angle of the multiple second outer gear rings 24 on the multiple transmission units are the same, but the number of teeth increases from bottom to top, and the number of teeth in two adjacent second outer gear rings 24 differs by one time. When the slide bar 22 rotates, the second outer gear ring 24 and the first outer gear ring 23 alternate between the meshing state and the disengagement state. When the slide bar 22 rotates one circle, the rotation angles of the multiple first outer gear rings 23 increase from bottom to top, and the rotation angles between two adjacent first outer gear rings 23 differ by one time.

[0060] In this embodiment, the top end of the sliding rod 22 passes through the top wall of the corresponding sliding groove 121 and extends out of the supporting column 12 and is fixedly connected to the rotating handle 221 .

[0061] By extending the top end of the slide bar 22 out of the support column 12 and fixedly connected to the rotating handle 221, the slide bar 22 can be directly controlled to rotate by hand, thereby facilitating the height adjustment of the support bar 13.

[0062] In this embodiment: the upper end of the slide rod 22 is also coaxially fixedly connected to a limit ring 222, and the limit ring 222 is sunk into the top wall of the corresponding slide groove 121 and rotates to fit.

[0063] The limiting ring 222 is provided to limit the sliding rod 22 from sliding on the supporting column 12 along the length direction of the supporting column 12 , so that the connection transmission between the sliding rod 22 and the second outer gear ring 24 is more stable.

[0064] In this embodiment: the inner circular surface of the second outer gear ring 24 is provided with a groove 241 extending in the axial direction, the side wall of the slide rod 22 is provided with a convex strip 223 adapted to the groove 241, and one side of the convex strip 223 is fixedly connected to the side wall of the slide rod 22, and the other side is inserted into the groove 241 and slidably fits.

[0065] A groove 241 is formed on the inner circumference of the second outer gear ring 24 , a convex strip 223 is provided on the side wall of the slide bar 22 , and the convex strip 223 is embedded in the groove 241 to limit the rotation of the second outer gear ring 24 and the slide bar 22 , so that multiple second outer gear rings 24 rotate synchronously with the slide bar 22 .

[0066] In this embodiment: a knocking bar 14 is provided above the plurality of support rods 13, the knocking bar 14 is parallel to the support rods 13, and both ends of the knocking bar 14 are respectively inserted into two slide grooves 121 and slide in cooperation, and the screw rod 21 and the slide rod 22 both penetrate the knocking bar 14;

[0067] A linkage assembly is provided between the knocking bar 14 and the slide bar 22 , and when the knocking bar 14 slides in the slide groove 121 , the slide bar 22 is driven to rotate through the linkage assembly.

[0068] By setting the knocking bar 14, both ends of the knocking bar 14 are T-shaped blocks adapted to the slide groove 121, so that the knocking bar 14 is connected to the support column 12 by sliding in a single degree of freedom along the length direction of the support column 12. When in use, the knocking bar 14 is moved to the bottom surface to abut against the top of the measuring rod 34, and the knocking bar 14 is hit by a hammer with the hand. The knocking bar 14 is forced to slide upward on the support column 12, pushing the measuring rod 34 to slide downward and insert into the soil. The force of different inclination angles applied by the hammer is converted to the length direction of the support column 12, that is, the length direction of the measuring rod 34 by the knocking bar 14, so that the measuring rod 34 can be stably inserted into the soil, further reducing the risk of bending and deformation of the measuring rod 34.

[0069] In this embodiment: the linkage assembly includes two meshing bevel gear rings 31, a gear 32 coaxially fixedly connected to one of the bevel gear rings 31, a rack 33 parallel to the slide groove 121 and fixedly connected to a side wall of the slide groove 121, and the other bevel gear ring 31 is sleeved outside the slide rod 22 and slides with a single degree of freedom along the axial direction of the slide rod 22;

[0070] The gear 32 is embedded in the knocking bar 14 and rotates together, and the gear teeth of the gear 32 protrude from the side wall of the knocking bar 14 and mesh with the rack 33.

[0071] During use, the knocking bar 14 is subjected to the impact force of the hammer and moves downward on the support column 12, and the knocking bar 14 pushes the probe 34 to move downward and insert into the soil; at the same time, the gear 32 moves downward with the knocking bar 14, and then the gear 32 and the rack 33 move relative to each other, and the rack 33 pushes the gear 32 to rotate forward, and the gear 32 drives the two slide bars 22 to rotate forward through the two bevel gear rings 31, and the slide bars 22 drive multiple support bars 13 to move downward and gather together; a part of the downward impact force of the knocking bar 14 is converted into the rotational force of the slide bar 22 through the linkage assembly composed of the gear 32, the rack 33, and the two bevel gear rings 31, thereby pushing the support bar 13 to move; that is, when the knocking bar 14 is hammered and moves downward, the probe 34 moves downward and inserts into the soil, and the multiple support bars 13 automatically move downward and gather together synchronously, providing the necessary space for the probe 34 to move downward.

[0072] In this embodiment: a placement hole 141 coaxial with the limiting hole 131 is opened in the middle of the knocking bar 14, and a plug hole 142 connected to the placement hole 141 is opened on the side wall of the knocking bar 14. A pin 143 is inserted in the plug hole 142, and the placement hole 141 is covered by the pin 143.

[0073] During use, when it is necessary to insert the drill, pull out the pin 143 from the socket 142 to open the placement hole 141, then align the sharp end of the probe 34 with the placement hole 141 and slowly lower it, so that the sharp end of the probe 34 passes through the placement hole 141 and the multiple limit holes 131 on the multiple support rods 13 in turn, and finally abuts against the slope surface, insert the pin 143 into the socket 142, cover and seal the placement hole 141, press the knocking bar 14 downward or rotate the handle 221 forward, so that the knocking bar 14 moves downward and approaches the probe 34, until the top of the probe 34 is inserted into the placement hole 141 and abuts against the pin 143, use a hammer or other equipment to hammer the knocking bar 14, and push the probe 34 downward through the knocking bar 14 to insert it into the soil to perform the drill insertion work.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
