Description

TECHNICAL FIELD

[0002] In geographic information surveying and mapping, soil sampling is a key link for analyzing geological structure, nutrient distribution and environmental carrying capacity.

[0003] Traditional auger rod sampling devices are widely used due to their simple operation and large soil sampling depth. However, when the auger rod lifts the soil by relying on the blade groove, the radial extrusion force generated by rotation and downward pressure can cause soil structure damage, seriously affecting the accuracy of subsequent laboratory analysis. In addition, in the sampling of soil samples at the blade groove position of the auger rod, the traditional method loosens the soil by knocking, and then uses a plastic scraper, a wood piece, a wide-head screwdriver (non-sharp end), or a special sampling knife to carefully scrape or pry the soil out of the blade gap along the direction of the spiral blade groove, and the sample is directly scraped into a sample bag, a sample box or a tray.

[0046] In this embodiment, as shown in Figures 1 to 20As shown, the pushing mechanism 5 comprises a connecting pipe 501 sleeved in the inside of the auger rod 3, the top of the connecting pipe 501 is threadedly connected between the bottom of the fixed rod 405, the surface of the connecting pipe 501 is equidistantly provided with a plurality of guide discs 502, the surface of the guide disc 502 is provided with a cam groove 5021, the surface of the auger rod 3 is equidistantly provided with a plurality of arc-shaped movable grooves 503, the plurality of arc-shaped movable grooves 503 correspond to the plurality of guide discs 502 one by one, the middle part of the arc-shaped movable groove 503 is provided with a first through groove 5031, the top wall of the first through groove 5031 is provided with a waist-shaped groove 5032, the cam groove 5021 is slidably provided with a guide block 504, one end of the guide block 504 is movably installed on the first through groove 5031, the top of one end of the guide block 504 is fixedly connected with a fixed pin 5041, the upper end of the fixed pin 5041 is slidably installed in the adjacent waist-shaped groove 5032, the end of the guide block 504 is fixedly connected with an arc-shaped pushing tooth 505, the arc-shaped pushing tooth 505 is located in the inside of the adjacent arc-shaped movable groove 503, the surface of the arc-shaped pushing tooth 505 is sleeved with a rubber sleeve 5051, and the rubber sleeve 5051 is attached to the inner wall of the arc-shaped movable groove 503.

[0052] It should be noted here that the top of the L-shaped limiting pin 6012 is provided with an inclined surface. When the rectangular sleeve 705 moves close to the top of the L-shaped limiting pin 6012, the bottom of the rectangular sleeve 705 will be pressed on the inclined surface of the top of the L-shaped limiting pin 6012, so that the L-shaped limiting pin 6012 moves downward, thereby preventing the movement of the rectangular sleeve 705;

[0053] When the soil sampling is carried out by rotating the auger rod 3 counterclockwise driven by the second motor 401 and lifting the lifting plate 203 on the lead screw 202 driven by the first motor 201 after the soil drilling is completed by lowering the auger rod 3, the upper end of the L-shaped limiting pin 6012 is moved out of the limiting groove 6011 by pressing the L-shaped limiting pin 6012, at this time, the second spring 7033 is elastically reset, the pressing rod 703 is pushed up, the two connecting pins 7031 symmetrically arranged at the bottom of the pressing rod 703 are moved up in the arc-shaped groove 7021, the arc-shaped groove 7021 is arranged on the side, so that the second rotating sleeve 702 is rotated during the upward movement of the pressing rod 703, after the connecting pin 7031 is lifted into place, the second rotating sleeve 702 is rotated by 90 degrees, and during the rotation of the second rotating sleeve 702, the second tooth ring 708 fixed on the upper end surface of the second rotating sleeve 702 is engaged with the second gear 709 on the movable sampling plate 707, so that the movable sampling plate 707 is rotated by 90 degrees around the second gear 709 as the axis, at this time, the movable sampling plate 707 is in the same horizontal direction as the fixed sampling plate 706, one end of the movable sampling plate 707 after rotation is arranged on the tangent surface of the outer wall axis of the auger rod 3, during the overturning and upward movement of the auger rod 3, the soil in the auger blade groove can be scraped into the movable sampling plate 707, and the scraped soil is transported from the movable sampling plate 707 to the fixed sampling plate 706.

[0054] In this embodiment, as shown in Figures 1 to 20 The segmented mechanism 8 includes a rotating disc 801 and a ratchet wheel 802, the rotating disc 801 is rotatably installed on the surface of the lower end of the lead screw 202, it should be noted that the rotating disc 801 is rotatably installed on the surface of the lead screw 202 through a bearing, the ratchet wheel 802 is fixedly installed on the surface of the lower end of the lead screw 202, the ratchet wheel 802 is located below the rotating disc 801, a pawl 803 is rotatably installed on one side of the bottom of the rotating disc 801, a fixed column 804 is fixedly connected to the bottom of the rotating disc 801, a spring sheet 805 is fixedly installed on the fixed column 804, one side of the spring sheet 805 is arranged on the surface of one end of the pawl 803, a fixed sleeve 807 is fixedly installed on the top of the mounting plate 6, a limiting rod 806 is movably arranged in the middle of the fixed sleeve 807, one end of the limiting rod 806 is arranged on the surface of the other end of the pawl 803, the other end of the limiting rod 806 is fixedly installed on the surface of one end of the rectangular sleeve 705, a third spring 808 is sleeved on the surface of the other end of the limiting rod 806, and the two ends of the third spring 808 are fixedly installed between one side of the fixed sleeve 807 and the surface of the rectangular sleeve 705, and a cutting assembly 809 is arranged on the top of the rotating disc 801.

[0055] When the pressing rod 703 moves downward and the limiting assembly 601 locks the rectangular sleeve 705, the limiting rod 806 at one end of the rectangular sleeve 705 abuts against the surface of the pawl 803, and the elastic sheet 805 elastically resets to push the pawl 803 to rotate, and at this time, the one end of the pawl 803 is separated from the ratchet wheel 802. When the limiting assembly 601 is unlocked from the rectangular sleeve 705, the second spring 7033 pushes the pressing rod 703 to move upward, and the connecting ring 7032 drives the Z-shaped push rod 704 to move upward, so that the Z-shaped push rod 704 moves under the action of the wedge structure through the setting of the middle inclined surface, drives the rectangular sleeve 705 to move, and the rectangular sleeve 705 drives the limiting rod 806 to move and unlock the pawl 803, and the elastic reset of the third spring 808 can further accelerate the movement of the rectangular sleeve 705.

When the pressing rod 703 moves downward and the Z-shaped push rod 704 drives the rectangular sleeve 705 to move reversely and reset, the rectangular sleeve 705 drives the limiting rod 806 to move to the other end of the pawl 803, and when the ratchet wheel 802 drives the rotating disc 801 to rotate, the other end of the pawl 803 on the rotating disc 801 is extruded by the limiting rod 806 again, so that the pawl 803 reversely deflects and resets, and the insertion state with the ratchet wheel 802 is unlocked. When the ratchet wheel 802 rotates, the rotating disc 801 will not rotate again, so that when the auger 3 rotates clockwise to drill soil, the cutting assembly 809 will not cut the soil, and when the auger 3 reverses to sample soil, the soil can be segmented.

[0059] It needs to be supplemented here that the bottom of one end of the fixed sampling plate 706 has a through hole, and the blanking plate 9082 is located on the through hole at the bottom of one end of the fixed sampling plate 706, and corresponds to the sample receiving box 10, when the cutter 8097 moves to the fixed sampling plate 706 and approaches the soil sample in the fixed sampling plate 706, the cutter 8097 will extrude the surface of the sealing plate 903 after completing the slitting of the soil sample by continuing to move, so that the sealing plate 903 moves to the inside of the second through groove 901, at this time, the sealing plate 903 drives the two symmetric sliding plates 902 to move, so that the mounting pin 9051 in the inclined groove 9021 on the surface of the sliding plate 902 moves downward along the inclined groove 9021, so that the mounting pin 9051 drives the movable rod 905 to descend, the second rack 907 at the bottom of the movable rod 905 is engaged with the third gear 909 at the end of the rotating rod 908, so that the third gear 909 drives the blanking plate 9082 fixedly connected with the first connecting sleeve 9081 to turn downward, at this time, the bottom of one end of the fixed sampling plate 706 is in an open state, and the cut soil sample falls on the surface of the sample receiving box 10 and then falls, and is collected by the operator, so that the automatic blanking of the cut soil sample is realized, and the collection of the sample by the operator is facilitated.

[0060] The use method and advantages of the present application are as follows:

[0061] As Figures 1 to 20As shown, in the process of drilling clay soil samples by the geographic information collection surveying device, first, the second motor 401 drives the first gear 402 to rotate, so that the first gear 402 meshes with the first tooth ring 404 fixed on the surface of the first rotating sleeve 403, and the first tooth ring 404 drives the screw drill rod 3 installed at the lower end of the first rotating sleeve 403 to rotate clockwise. In the process of rotating the screw drill rod 3 by the transmission mechanism 4, the first motor 201 drives the screw rod 202 to rotate, so that the lifting plate 203 on the screw rod 202 is guided to rise and fall by the guide rod 204, and the rotating screw drill rod 3 performs soil sampling operation;

[0062] In the process of drilling by the screw drill rod 3, the connecting pipe 501 inside the screw drill rod 3 is fixedly connected with the bottom of the fixed rod 405, so that the guide disc 502 on the connecting pipe 501 does not rotate when the screw drill rod 3 rotates. At this time, the arc-shaped push teeth 505 on the surface of the screw drill rod 3 will drive the fixed guide block 504 to rotate along the cam groove 5021 on the surface of the guide disc 502. In the process of rotating the guide block 504 along the cam groove 5021, when one end of the guide block 504 approaches the surface of the connecting pipe 501, the guide block 504 drives the arc-shaped push teeth 505 to move towards the inside of the arc-shaped movable groove 503. When one end of the guide block 504 is away from the surface of the connecting pipe 501, the guide block 504 drives the arc-shaped push teeth 505 to move towards the outside of the arc-shaped movable groove 503. At the same time, in the process of moving the guide block 504, the fixed pin 5041 at the top of the guide block 504 moves along the extension direction of the waist-shaped groove 5032, drives the arc-shaped push teeth 505 to move upwards and slightly deflect by a certain angle, so as to push the soil in the spiral blade groove of the screw drill rod 3, which can reduce the excessive extrusion of the soil in the process of drilling the soil by the screw drill rod 3, thereby reducing the disturbance to the soil;

[0063] After the auger 3 is lowered to complete the drilling of the soil, the auger 3 is rotated counterclockwise by the second motor 401, and the lifting plate 203 on the lead screw 202 is lifted by the first motor 201, and when soil sampling is performed, the upper end of the L-shaped limiting pin 6012 is moved out of the limiting groove 6011 by pressing the L-shaped limiting pin 6012, and at this time the second spring 7033 is elastically reset to push the pressing rod 703 upward, so that the two connecting pins 7031 symmetrically arranged at the bottom of the pressing rod 703 move upward in the arc-shaped groove 7021, and the arc-shaped groove 7021 is arranged on the side to make the pressing rod 703 rotate the second rotating sleeve 702 when the pressing rod 703 rises, and after the connecting pin 7031 rises to the position, the second rotating sleeve 702 completes 90 degrees of rotation, and during the rotation of the second rotating sleeve 702, the second gear ring 708 fixed on the upper end surface of the second rotating sleeve 702 is engaged with the second gear 709 on the movable sampling plate 707, so that the movable sampling plate 707 rotates 90 degrees around the second gear 709 as the axis, at this time the movable sampling plate 707 is in the same horizontal direction as the fixed sampling plate 706, and one end of the movable sampling plate 707 after rotation is arranged on the tangent surface of the outer wall axis of the auger 3, and during the rotation and upward movement of the auger 3, the soil in the auger blade groove can be scraped into the movable sampling plate 707, so that the scraped soil is transported from the movable sampling plate 707 to the fixed sampling plate 706;

[0064] In addition, when the movable sampling plate 707 is not needed to scrape the soil for sampling, the pressing rod 703 is pressed downward to make the connecting pin 7031 at the bottom of the pressing rod 703 move downward in the arc-shaped groove 7021, so that the second rotating sleeve 702 is reversed, and at the same time the second gear ring 708 at the upper end of the second rotating sleeve 702 is engaged with the second gear 709 on the movable sampling plate 707 again, so that the movable sampling plate 707 is flipped 90 degrees and reset after the rotation, which is convenient for subsequent drilling of the auger 3 without interference;

[0065] When the pressing rod 703 is lowered to lock the rectangular sleeve 705 by the limiting assembly 601, the limiting rod 806 at one end of the rectangular sleeve 705 abuts against the surface of the pawl 803 to limit the elastic reset of the elastic sheet 805 to push the pawl 803 to rotate, and at this time the one end of the pawl 803 is separated from the ratchet wheel 802;

[0066] When the limiting assembly 601 is unlocked from the rectangular sleeve 705, the second spring 7033 pushes the pressure rod 703 upwards, and the connecting ring 7032 drives the Z-shaped push rod 704 upwards, so that the Z-shaped push rod 704 moves the rectangular sleeve 705 through the setting of the middle inclined surface, and under the action of the wedge structure, drives the rectangular sleeve 705 to move, so that the rectangular sleeve 705 drives the limiting rod 806 to move and releases the limiting of the pawl 803, and the elastic reset of the third spring 808 can further speed up the movement of the rectangular sleeve 705. After the limiting rod 806 releases the limiting of the pawl 803, the elastic sheet 805 is elastically reset, and the pawl 803 is pressed and driven to be deflected with the rotating disc 801 as the shaft, so that one end of the pawl 803 is inserted into the teeth of the ratchet wheel 802. When the lead screw 202 drives the ratchet wheel 802 to rotate, the rotating disc 801 can be driven to rotate, and the rotating disc 801 rotates;

[0067] At this time, the arc-shaped rack 8096 fixed on the rotating disc 801 will intermittently mesh with the first rack 8092, driving the cutter 8097 on the first rack 8092 to move towards the fixed sampling plate 706. The cutter 8097 cuts the soil, and when the arc-shaped rack 8096 is disengaged from the first rack 8092, the compressed fourth spring 8095 is elastically reset, driving the connecting block 8094 fixed on the first rack 8092 to quickly reset, realizing the movement and reset of the cutter 8097, so that the cutter 8097 automatically segments the soil on the inner wall of the fixed sampling plate 706;

[0068] When the cutter 8097 moves towards the fixed sampling plate 706 to cut the soil sample in the fixed sampling plate 706, the cutter 8097 will press the surface of the sealing plate 903 after completing the cutting of the soil sample, and the sealing plate 903 will move towards the inside of the second through groove 901. At this time, the sealing plate 903 drives the two symmetrical sliding plates 902 to move, so that the installation pin 9051 in the inclined groove 9021 on the surface of the sliding plate 902 moves downward along the inclined groove 9021, so that the installation pin 9051 drives the movable rod 905 to descend, and the second rack 907 at the bottom of the movable rod 905 meshes with the third gear 909 at the end of the rotating rod 908, so that the third gear 909 drives the first connecting sleeve 9081 fixed with the lower plate 9082 to overturn downward. At this time, the bottom of one end of the fixed sampling plate 706 is in an open state, and the cut soil sample falls on the surface of the sample receiving box 10 and then falls, and is collected by the operator, so as to realize the automatic discharge of the cut soil sample, and facilitate the collection of the sample by the operator.
