Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping devices, in particular to a geographic information collection and surveying and mapping device. Background Art

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

[0003] Traditional spiral drill rod sampling devices are widely used due to their ease of operation and large soil sampling depth. However, when the spiral drill rod relies on the blade groove to lift the soil, the radial extrusion force generated by the rotation and downward pressure can cause damage to the soil structure, seriously affecting the accuracy of subsequent laboratory analysis. In addition, in sampling soil samples at the blade groove position on the spiral drill rod, the traditional method is to loosen the soil by knocking, and then use a plastic scraper, wood chip, wide-head screwdriver (non-sharp end) or a special sampling knife to carefully scrape or pry out the soil from the blade gap along the direction of the spiral blade groove, and scrape the sample directly into a sample bag, sample box or tray. Improper operation of the above existing methods can easily disturb or destroy the soil structure, affecting the accuracy of subsequent detection. Summary of the Invention

DETAILED DESCRIPTION

[0040] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] Please refer to Figures 1 to 20 The present application provides a technical solution: a geographic information acquisition and mapping device, comprising a device body 1, a lifting mechanism 2 is arranged on the device body 1, and a screw drill rod 3 is arranged on the lifting mechanism 2;

[0042] A transmission mechanism 4 for rotating the screw drill rod 3 is arranged between the lifting mechanism 2 and the screw drill rod 3, a soil sample extrusion reducing mechanism 5 is arranged between the inside of the screw drill rod 3 and the transmission mechanism 4, an installation plate 6 is fixedly installed on one side of the front end of the device body 1, a sampling mechanism 7 for scraping soil samples on the surface of the screw drill rod 3 is arranged on the installation plate 6, a sampling soil falling discharging assembly 9 is arranged at one end of the sampling mechanism 7, a segmentation mechanism 8 for automatically segmenting the sampled soil is arranged between the sampling mechanism 7 and the lower end of the lifting mechanism 2, and a sample receiving box 10 is obliquely fixedly installed on one end of the front side of the device body 1.

[0043] In the embodiment, as shown in Figures 1 to 20 The lifting mechanism 2 comprises a first motor 201, the first motor 201 is fixedly installed on the top of the device body 1, the output end of the first motor 201 is fixedly connected with a lead screw 202, and the bottom of the lead screw 202 is rotatably installed on the bottom of the device body 1. It should be noted that the upper and lower ends of the lead screw 202 are rotatably installed on the device body 1 through bearings, a lifting plate 203 is screw-mounted on the surface of the lead screw 202, guide rods 204 are movably and perpendicularly arranged at both ends of the lifting plate 203, the guide rods 204 are fixedly installed between the top wall of the device body 1 and the bottom of the device body 1, and the transmission mechanism 4 is arranged between the screw drill rod 3 and the lifting plate 203. In the process of rotating the screw drill rod 3 by the transmission mechanism 4, the first motor 201 drives the lead screw 202 to rotate, the lifting plate 203 on the lead screw 202 is lifted and lowered under the guidance of the guide rods 204, and soil sampling is performed by the rotating screw drill rod 3.

[0044] In the embodiment, as shown in Figures 1 to 20As shown, the transmission mechanism 4 includes a second motor 401 and a first rotating sleeve 403. It should be added here that the first rotating sleeve 403 is I-shaped, and the outer wall of the first rotating sleeve 403 is rotatably installed between the inner part of the lifting plate 203 through a bearing. In addition, a number of balls are equidistantly installed on the top wall and bottom wall of the first rotating sleeve 403. One side of the ball is mounted on the upper and lower surfaces of the lifting plate 203. During the rotation of the first rotating sleeve 403, the friction between the top wall and bottom wall of the first rotating sleeve 403 and the lifting plate 203 is reduced, thereby improving the stability of the rotation of the first rotating sleeve 403. The second motor 401 is fixedly mounted on the top of the lifting plate 203, the output end of the second motor 401 is fixedly connected to the first gear 402, the first rotating sleeve 403 is rotatably mounted on the lifting plate 203, the outer wall of the first rotating sleeve 403 is fixedly mounted with a first gear ring 404, and one side of the first gear ring 404 is meshed with one side of the first gear 402, the middle part of the first rotating sleeve 403 is sleeved with a fixed rod 405, and the top of the fixed rod 405 is fixedly mounted on the top of the lifting plate 203, and the lower end of the first rotating sleeve 403 is threadedly mounted with the top of the auger rod 3. It should be added here that the threaded installation between the auger rod 3 and the first rotating sleeve 403 facilitates the addition of a casing to the upper end of the auger rod 3 to increase the drilling depth of the geographic information collection and surveying device, and when adding the casing, both ends of the casing are threadedly mounted between the top of the auger rod 3 and the bottom of the first rotating sleeve 403, which is convenient for disassembly.

[0045] When soil samples are taken through the auger rod 3, the output of the second motor 401 drives the first gear 402 to rotate, so that the first gear 402 engages with the first gear ring 404 fixed on the surface of the first rotating sleeve 403, so that the first gear ring 404 drives the auger rod 3 installed at the lower end of the first rotating sleeve 403 to rotate clockwise. The auger rod 3 driven by the lifting mechanism 2 to rotate descends to perform soil sampling operations. Through the rotation of the auger rod 3, as the auger rod 3 slowly descends, the spiral curved blade at the bottom of the auger rod 3 drives the drill bit to cut into the soil layer through clockwise rotation. The cut soil moves upward along the groove of the spiral blade during the rotation process, so as to facilitate the extraction of soil samples at different depths in the same borehole.

[0046] In this embodiment, Figures 1 to 20As shown, the sample pushing mechanism 5 includes a connecting tube 501, which is sleeved inside the auger rod 3, and the top of the connecting tube 501 is threadedly connected to the bottom of the fixed rod 405. A plurality of guide plates 502 are equidistantly installed on the surface of the connecting tube 501, and a cam groove 5021 is provided on the surface of the guide plate 502. A plurality of arc-shaped movable grooves 503 are equidistantly provided on the surface of the auger rod 3, and the plurality of arc-shaped movable grooves 503 correspond to the plurality of guide plates 502 one by one. A first through groove 5031 is provided in the middle of the arc-shaped movable groove 503, and a top wall of the first through groove 5031 is provided. A guide block 504 is slidably mounted on the waist-shaped groove 5032 and the cam groove 5021, and one end of the guide block 504 is movably mounted on the first through groove 5031. A fixing pin 5041 is fixedly connected to the top of one end of the guide block 504, and the upper end of the fixing pin 5041 is slidably mounted in the adjacent waist-shaped groove 5032. An arc-shaped pushing tooth 505 is fixedly connected to the end of the guide block 504, and the arc-shaped pushing tooth 505 is located inside the adjacent arc-shaped movable groove 503. A rubber sleeve 5051 is sheathed on the surface of the arc-shaped pushing tooth 505, and the rubber sleeve 5051 is in contact with the inner wall of the arc-shaped movable groove 503. It should be noted that the rubber sleeve 5051 has a certain degree of elasticity. When squeezed, it can shrink slightly. When no longer squeezed, the elasticity is restored, so that the rubber sleeve 5051 can always be in contact with the inner wall of the arc-shaped movable groove 503, thereby improving the sealing performance.

[0047] When the auger rod 3 is drilling, since the connecting tube 501 inside the auger rod 3 is fixedly connected to the bottom of the fixed rod 405, when the auger rod 3 rotates, the guide plate 502 on the connecting tube 501 does not rotate. At this time, the several arc-shaped pushing teeth 505 on the surface of the auger rod 3 drive the fixed guide block 504 to rotate along the cam groove 5021 on the surface of the guide plate 502. When the guide block 504 rotates along the cam groove 5021, when one end of the guide block 504 approaches the surface of the connecting tube 501, the guide block 504 drives the arc-shaped pushing teeth 505 to move inside the arc-shaped movable groove 503. When one end of the guide block 504 moves away from the surface of the connecting tube 501, the guide block 504 pushes the arc-shaped pushing teeth 505 to move outside the arc-shaped movable groove 503. At the same time, when the guide block 504 moves, the guide block 50 The fixing pin 5041 at the top moves along the extension direction of the waist-shaped groove 5032, driving the arc-shaped pushing tooth 505 to move upward and slightly deflect at a certain angle. This is repeated to achieve intermittent pushing of the soil sample, thereby pushing the soil in the groove of the spiral blade of the auger rod 3. This can reduce excessive squeezing of the soil by the auger rod 3 during drilling, thereby reducing the disturbance of the soil and improving the accuracy of subsequent laboratory analysis. Since the fixing pin 5041 moves a short distance in the waist-shaped groove 5032, the guide block 504 is limited in its rising height and will not move out of the cam groove 5021. After the guide block 504 pushes the arc-shaped pushing tooth 505 into place, the arc-shaped pushing tooth 505 is flush with the outer wall of the arc-shaped movable groove 503, and will not affect the scraping work of the movable sampling plate 707.

[0048] In this embodiment, Figures 1 to 20As shown, the sampling mechanism 7 comprises a bracket 701 fixedly installed on the top of the mounting plate 6, the upper end of the bracket 701 is rotatably installed with a second rotating sleeve 702, it should be added here that the bottom of the second rotating sleeve 702 is rotatably installed on the mounting plate 6 through a bearing, improving the stability of the rotation of the second rotating sleeve 702, and the side wall of the second rotating sleeve 702 is symmetrically provided with an arc-shaped groove 7021, a pressing rod 703 is movably arranged in the second rotating sleeve 702, and connecting pins 7031 are fixedly installed on the lower end of the pressing rod 703, one end of the connecting pin 7031 is movably installed in the adjacent arc-shaped groove 7021, and a connecting ring 7032 is fixedly installed between the one ends of the two connecting pins 7031, the connecting ring 7032 is sleeved on the outside of the second rotating sleeve 702, Z-shaped push rods 704 are symmetrically fixedly connected to the bottom of the connecting ring 7032, a rectangular sleeve 705 is slidably installed between the surfaces of the two Z-shaped push rods 704, the segment mechanism 8 is arranged between one end of the rectangular sleeve 705 and the lower end of the lifting mechanism 2, and the limit component 601 is arranged between the bottom of the rectangular sleeve 705 and the mounting plate 6, one side of the upper end of the bracket 701 is fixedly connected with a fixed sampling plate 706, and the one end of the fixed sampling plate 706 is hingedly installed with a movable sampling plate 707, it should be added here that the fixed sampling plate 706 and the movable sampling plate 707 are both U-shaped, the scraped soil sample is conveyed to the through port position at the bottom of the one end of the fixed sampling plate 706 through the U-shaped groove, the blanking assembly 9 is arranged on the one end of the fixed sampling plate 706, the surface of the upper end of the second rotating sleeve 702 is fixedly installed with a second tooth ring 708, and the second tooth ring 708 is engaged with a second gear 709 on one side, the second gear 709 is fixedly installed at the hinge between the movable sampling plate 707 and the fixed sampling plate 706, it should be added here that the upper and lower sides of the one end of the fixed sampling plate 706 are rotatably installed with a pin shaft, and the pin shaft is fixedly installed on the movable sampling plate 707, the second gear 709 is fixedly connected with the corresponding pin shaft, when the second tooth ring 708 is engaged with the second gear 709, the second gear 709 drives the movable sampling plate 707 to rotate 90 degrees at the pin shaft on the one end of the fixed sampling plate 706, so that the one end of the rotated movable sampling plate 707 is arranged on the tangent surface of the outer wall shaft center of the auger rod 3, at this time, the fixed sampling plate 706 and the movable sampling plate 707 are on the same horizontal line, in the reverse rotation of the auger rod 3, the soil in the spiral blade groove can be scraped into the movable sampling plate 707, the upper end of the pressing rod 703 is sleeved with a second spring 7033, and the upper end of the second spring 7033 is fixedly connected with the top wall of the pressing rod 703, and the bottom wall of the second spring 7033 is arranged on the surface of the second tooth ring 708.

[0049] When the soil scraping sampling is not needed to use the movable sampling plate 707, the connecting pin 7031 at the bottom of the pressing rod 703 is lowered in the arc-shaped slot 7021 by pressing the pressing rod 703 to descend, so that the second rotating sleeve 702 is reversed, and the second gear ring 708 at the upper end of the second rotating sleeve 702 is re-engaged with the second gear 709 on the movable sampling plate 707, so that the movable sampling plate 707 is flipped by 90 degrees and is reset, thereby facilitating the subsequent drilling of the soil by the auger rod 3 without interference.

[0051] In the embodiment, as shown in the figure, Figures 1 to 20 The limiting assembly 601 includes a limiting slot 6011, which is provided at the bottom of the other end of the rectangular sleeve 705. The bottom of one end of the mounting plate 6 is movably inserted with an L-shaped limiting pin 6012, and the upper end of the L-shaped limiting pin 6012 extends into the limiting slot 6011. The surface of the upper end of the L-shaped limiting pin 6012 is fixedly installed with a fixed ring 6013, and the surface of the upper end of the L-shaped limiting pin 6012 is sleeved with a first spring 6014, and the two ends of the first spring 6014 are fixedly installed between the bottom of the fixed ring 6013 and the top of the mounting plate 6.

[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] After the auger rod 3 is lowered and the soil is drilled, the second motor 401 drives the auger rod 3 to rotate counterclockwise, and the first motor 201 drives the lifting plate 203 on the screw rod 202 to rise. When soil sampling is performed, the L-shaped limit pin 6012 is pressed to make the upper end of the L-shaped limit pin 6012 move out of the limit groove 6011. At this time, the second spring 7033 elastically resets, pushing the pressure rod 703 to move upward, so that the two symmetrical connecting pins 7031 at the bottom of the pressure rod 703 move upward in the arc groove 7021. The arc-shaped side of the arc groove 7021 makes the pressure rod 703 drive the second rotating sleeve 702 to rotate during the rise. After the connecting pin 7031 rises to its position, The second rotating sleeve 702 completes a 90-degree 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 engages with the second gear 709 on the movable sampling plate 707, causing the movable sampling plate 707 to rotate 90 degrees with the second gear 709 as the axis. At this time, the movable sampling plate 707 and the fixed sampling plate 706 are at the same horizontal level. One end of the rotated movable sampling plate 707 is placed on the cross-section of the axis of the outer wall of the auger rod 3. When the auger rod 3 flips and moves upward, the soil in the spiral 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.

[0054] In this embodiment, Figures 1 to 20 As shown, the segmentation mechanism 8 includes a rotating disk 801 and a ratchet 802. The rotating disk 801 is rotatably mounted on the surface of the lower end of the screw rod 202. It should be noted that the rotating disk 801 is rotatably mounted on the surface of the screw rod 202 through a bearing, and the ratchet 802 is fixedly mounted on the surface of the lower end of the screw rod 202. The ratchet 802 is located below the rotating disk 801. A pawl 803 is rotatably mounted on one side of the bottom of the rotating disk 801. A fixed column 804 is fixedly connected to one side of the bottom of the rotating disk 801, and a spring 805 is fixedly mounted on the fixed column 804. One side of the spring 805 is mounted on the 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, and a limiting rod 806 is movably provided through the middle of the fixing sleeve 807, and one end of the limiting rod 806 is placed on the surface of the other end of the pawl 803, and the other end of the limiting rod 806 is fixedly installed on the surface of one end of the rectangular sleeve 705, and the surface of the other end of the limiting rod 806 is sleeved with a third spring 808, and the two ends of the third spring 808 are respectively fixedly installed between one side of the fixing sleeve 807 and the surface of the rectangular sleeve 705, and a cutting assembly 809 is provided on the top of the rotating disk 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. After the limiting rod 806 unlocks the pawl 803, the elastic reset of the elastic sheet 805 extrudes and pushes the pawl 803 to deflect with the hinge joint of the rotating disc 801 as the pivot, so that the one end of the pawl 803 is inserted into the tooth of the ratchet wheel 802, and the rotating disc 801 can be rotated while the ratchet wheel 802 is rotated by the lead screw 202, and the soil sample in the fixed sampling plate 706 is automatically segmented by the cutting assembly 809 on the rotating disc 801. 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.

[0056] In the embodiment, as Figures 1 to 20As shown, the cutting assembly 809 includes a sliding sleeve 8091, which is fixedly mounted on the device body 1. A first rack 8092 is slidably mounted on the inner wall of the sliding sleeve 8091. A sliding rod 8093 is fixedly mounted on the top of the sliding sleeve 8091, and a connecting block 8094 is mounted on the surface of the sliding rod 8093. One end of the connecting block 8094 is fixedly mounted on the surface of the first rack 8092. A fourth spring 8095 is mounted on the surface of the sliding rod 8093 to drive the connecting block 8094 to return to its original position. It should be noted that positioning blocks are fixedly installed at both ends of the slide rod 8093, and the bottom of the positioning block is fixedly installed on the slide sleeve 8091. In addition, the two ends of the fourth spring 8095 are respectively fixedly installed between the surface of one side of the connecting block 8094 and the adjacent positioning block surface. An arc-shaped rack 8096 is fixedly installed on one side of the top of the slide sleeve 8091, and the surface of the arc-shaped rack 8096 is engaged with the surface of the first rack 8092. A cutter 8097 is fixedly installed at one end of the first rack 8092.

[0057] As the rotating disk 801 rotates, the arc-shaped rack 8096 fixed on the rotating disk 801 will intermittently engage with the first rack 8092, driving the cutter 8097 on the first rack 8092 to move toward the fixed sampling plate 706, and the cutter 8097 cuts the soil. When the arc-shaped rack 8096 is disengaged from the first rack 8092, the compressed fourth spring 8095 elastically resets, driving the connecting block 8094 fixed on the first rack 8092 to quickly reset, thereby realizing the movement and reset of the cutter 8097, so that the cutter 8097 automatically divides the soil on the inner wall of the fixed sampling plate 706 into equidistant segments, avoiding the problem that the operator manually takes samples with the sampling knife, which may easily disturb or damage the soil structure due to improper operation.

[0058] In this embodiment, Figures 1 to 20As shown, the blanking component 9 includes a second through slot 901, which is opened inside the fixed sampling plate 706, and a slide 902 is symmetrically slidably installed on the inner wall of the second through slot 901. A sealing plate 903 is fixedly connected between the two slides 902, and one side of the sealing plate 903 is flush with the inner wall of one side of the fixed sampling plate 706. An inclined slot 9021 is opened on the surface of the slide 902, and a support plate 904 is fixedly installed on the inner wall of the second through slot 901, and a movable rod 905 is vertically movable through the middle of the support plate 904, and a mounting pin 9051 is symmetrically fixedly installed on the surface of the movable rod 905. The mounting pin 9051 is slidably installed in the adjacent inclined slot 9021, and the upper end of the movable rod 905 is sleeved with a reset spring Spring 906, and the two ends of the return spring 906 are respectively fixedly installed between the top wall of the movable rod 905 and the surface of the support plate 904, the bottom of the movable rod 905 is fixedly installed with a second rack 907, the bottom of one end of the fixed sampling plate 706 is fixedly installed with a second connecting sleeve 9083, and the middle of the second connecting sleeve 9083 is rotatably installed with a rotating rod 908, and one end of the rotating rod 908 is fixedly connected to a third gear 909, the surface of the third gear 909 is engaged with the surface of the second rack 907, and the two ends of the rotating rod 908 are fixedly installed with a first connecting sleeve 9081, and a blanking plate 9082 is fixedly connected between the two first connecting sleeves 9081, and the blanking plate 9082 is located at the bottom of one end of the fixed sampling plate 706.

[0059] It should be added here that the bottom of one end of the fixed sampling plate 706 has a through opening, and the blanking plate 9082 is located on the through opening at the bottom of one end of the fixed sampling plate 706 and corresponds to the sample box 10. When the cutter 8097 moves toward the fixed sampling plate 706 to cut the soil sample in the fixed sampling plate 706, the cutter 8097 will continue to move after completing the cutting of the soil sample, and will squeeze the surface of the sealing plate 903, causing the sealing plate 903 to move toward the inside of the second through groove 901. At this time, the sealing plate 903 drives the two symmetrical slides 902 to move, so that the inclined groove 9021 on the surface of the slide 902 is The mounting pin 9051 moves downward along the inclined slot 9021, so that the mounting pin 9051 drives the movable rod 905 to descend, and the second rack 907 at the bottom of the movable rod 905 engages with the third gear 909 at the end of the rotating rod 908, so that the third gear 909 drives the blanking plate 9082 fixed on the first connecting sleeve 9081 to flip 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 box 10 and falls down, and is collected by the operator, thereby realizing automatic unloading of the cut soil sample, which is convenient for the operator to collect the sample.

[0060] The use method and advantages of the present invention: The working process of the geographic information collection and mapping device is as follows:

[0061] like Figures 1 to 20As shown, when drilling clay soil samples for testing and analysis using the geographic information acquisition and mapping device, the output of the second motor 401 first drives the first gear 402 to rotate, causing the first gear 402 to engage with the first gear ring 404 fixed to the surface of the first rotating sleeve 403, causing the first gear ring 404 to drive the auger rod 3 mounted on the lower end of the first rotating sleeve 403 to rotate clockwise. As the transmission mechanism 4 drives the auger rod 3 to rotate, the output end of the first motor 201 drives the screw rod 202 to rotate, causing the lifting plate 203 on the screw rod 202 to rise and fall under the guidance of the guide rod 204, and the rotating auger rod 3 performs soil sampling operations;

[0062] During the drilling of the auger rod 3, since the connecting tube 501 inside the auger rod 3 is fixedly connected to the bottom of the fixed rod 405, when the auger rod 3 rotates, the guide plate 502 on the connecting tube 501 does not rotate. At this time, the several arc-shaped pushing teeth 505 on the surface of the auger rod 3 drive the fixed guide block 504 to rotate along the cam groove 5021 on the surface of the guide plate 502. When the guide block 504 rotates along the cam groove 5021, when one end of the guide block 504 approaches the surface of the connecting tube 501, the guide block 504 drives the arc-shaped pushing teeth 505 to move into the arc-shaped movable groove 503. When one end of the guide block 504 moves away from the surface of the connecting pipe 501, the guide block 504 pushes the arc-shaped pushing tooth 505 to move outside the arc-shaped movable groove 503. At the same time, when the guide block 504 moves, the fixing pin 5041 on the top of the guide block 504 moves along the extension direction of the waist-shaped groove 5032, driving the arc-shaped pushing tooth 505 to move upward and slightly deflect at a certain angle, thereby pushing the soil in the groove of the spiral blade of the auger rod 3, which can reduce the excessive squeezing of the soil by the auger rod 3 during drilling, thereby reducing the disturbance of 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 locking cam 705 is unlocked, the locking cam 706 is released, and the locking cam 706 is unlocked, so that the locking cam 706 is unlocked and the locking cam 706 is unlocked.

[0067] At this time, the arc-shaped rack 8096 fixed on the rotating disk 801 will intermittently engage with the first rack 8092, driving the cutter 8097 on the first rack 8092 to move toward the fixed sampling plate 706, and the cutter 8097 cuts the soil. When the arc-shaped rack 8096 is disengaged from the first rack 8092, the compressed fourth spring 8095 elastically resets, 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 toward the fixed sampling plate 706 and approaches to cut the soil sample in the fixed sampling plate 706, the cutter 8097 will continue to move after completing the cutting of the soil sample, and will press on the surface of the sealing plate 903, so that the sealing plate 903 moves toward the inside of the second through groove 901. At this time, the sealing plate 903 drives the two symmetrical slides 902 to move, so that the mounting pin 9051 in the inclined groove 9021 on the surface of the slide 902 moves downward along the inclined groove 9021, so that the mounting pin 9051 brings The movable rod 905 is moved downward, and the second rack 907 at the bottom of the movable rod 905 engages with the third gear 909 at the end of the rotating rod 908, so that the third gear 909 drives the blanking plate 9082 fixed on the first connecting sleeve 9081 to flip 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 box 10 and falls down. It is then collected by the operator, thereby realizing automatic unloading of the cut soil sample and facilitating the operator to collect the sample.
