[0041] Example 1

[0042] like Figures 1 to 9As shown, the present invention discloses an engineering geological survey sampling device, comprising a support base 1, a vertical sampling mechanism 6, a partition 7, an arc-shaped baffle 10 and an adjustment mechanism 12, a limit assembly 2 is arranged on the upper part of the support base 1, a threaded rod 3 is arranged between the support base 1 and the limit assembly 2, a threaded sleeve 4 is threadedly arranged on the threaded rod 3, and a support plate 5 is rotatably arranged at the bottom end of the threaded sleeve 4;

[0043] The vertical sampling mechanism 6 is arranged on the support plate 5. The vertical sampling mechanism 6 comprises a sampling drill tube 601 rotatably arranged at the bottom side of the support plate 5. A sampling drill bit 602 is arranged at the bottom end of the sampling drill tube 601. The vertical sampling mechanism 6 can collect a long continuous soil sample.

[0044] The partition 7 is disposed inside the sampling drill tube 601, and the partition 7 divides the inside of the sampling drill tube 601 into a first collecting chamber 8 and a second collecting chamber 9, which are used to collect different soil samples;

[0045] The arc-shaped baffle 10 is slidably arranged in the second collecting chamber 9, and a transverse sampling mechanism 11 is arranged on the inner side of the arc-shaped baffle 10 for layered sampling of soil at different depths. The transverse sampling mechanism 11 includes an electric push rod 1101 arranged on the inner side of the arc-shaped baffle 10, and a moving plate 1102 is arranged on the side of the electric push rod 1101 away from the arc-shaped baffle 10, and a plurality of sampling tubes 1103 are arranged on the side of the moving plate 1102 away from the partition 7. The transverse sampling mechanism 11 can be used to perform layered sampling of soil;

[0046] The adjusting mechanism 12 is arranged in the second collecting chamber 9, and is used for adjusting the use position of the arc baffle 10. The adjusting mechanism 12 includes a first motor 1201 rotatably arranged in the second collecting chamber 9. A worm 1202 is arranged on the output shaft of the first motor 1201, and the end of the worm 1202 away from the first motor 1201 is rotatably connected to the inner wall of the second collecting chamber 9. The adjusting mechanism 12 can be used to adjust the use position of the arc baffle 10 according to the sampling situation.

[0047] The vertical sampling mechanism 6 further includes an L-shaped plate 603 disposed on the support plate 5, a connecting rod 604 is rotatably disposed between the L-shaped plate 603 and the support plate 5, the bottom end of the connecting rod 604 is connected to the upper end of the sampling drill tube 601, a second motor 605 is disposed on the upper side of the L-shaped plate 603, and the output shaft of the second motor 605 is connected to the top end of the connecting rod 604;

[0048] The outer sides of the connecting rod 604 and the threaded sleeve 4 are both provided with pulleys 13, and a connecting belt 14 is provided between the two pulleys 13;

[0049] The limiting assembly 2 includes two limiting rods 201 arranged at the upper end of the support base 1. The two limiting rods 201 are symmetrically distributed at the upper end of the support base 1 with the threaded rod 3 as the center. The upper ends of the two limiting rods 201 are provided with the same top plate 202. The two ends of the threaded rod 3 are respectively rotatably connected to the bottom side of the top plate 202 and the upper side of the support base 1, and the limiting rods 201 and the threaded rod 3 both pass through the support plate 5.

[0050] It should be noted that when sampling the soil, the second motor 605 drives the connecting rod 604 to rotate, the connecting rod 604 rotates to drive the sampling drill barrel 601 to rotate, and the sampling drill barrel 601 rotates to drive the sampling drill bit 602 to rotate. At the same time, during the rotation of the connecting rod 604, the cooperation of the pulley 13 and the connecting belt 14 can drive the threaded sleeve 4 to rotate synchronously. The rotation of the threaded sleeve 4 can drive the support plate 5 to move downward by utilizing the cooperation of the threaded rod 3 and the limiting rod 201, so that the downward movement of the support plate 5 can drive the rotating sampling drill barrel 601 to move downward. After the sampling drill bit 602 is inserted into the soil, the soil sample can enter the first collection chamber 8, and then a long continuous soil sample can be collected.

[0051] The transverse sampling mechanism 11 further includes an annular pressure sensor 1104 disposed at one end of the sampling tube 1103 away from the moving plate 1102 , and a serrated ring 1105 is disposed at one end of the annular pressure sensor 1104 away from the sampling tube 1103 .

[0052] It should be noted that, as mentioned above, after collecting the long continuous soil sample, the electric push rod 1101 can drive the moving plate 1102 to move, and the movement of the moving plate 1102 can drive the sampling tube 1103 to move. At this time, one end of the sampling tube 1103 can be moved out of the second collecting chamber 9, and during the movement of the sampling tube 1103, the sawtooth ring 1105 will first contact the soil. At this time, the annular pressure sensor 1104 can be used to detect the pressure on the sawtooth ring 1105, and then multiple sampling tubes 1103 can be used to perform layered sampling of the soil at different depths, so that the long continuous soil sample and the layered soil samples at different depths can be collected at the same time, making the sampling of the soil sample more comprehensive;

[0053] The adjusting mechanism 12 further comprises a rotating rod 1203 rotatably arranged in the second collecting chamber 9, a pair of gears 1204 and a worm wheel 1205 are arranged on the rotating rod 1203, and the worm wheel 1205 is meshed with the worm 1202, and two symmetrically distributed tooth plates 15 are arranged on one side of the arc-shaped baffle plate 10 close to the partition plate 7, and the tooth plates 15 are meshed with the gears 1204;

[0054] The second collecting chamber 9 is provided with two symmetrically distributed guide rods 19 , on which a slide block 20 is slidably provided, and a side of the slide block 20 away from the guide rod 19 is connected to the toothed plate 15 .

[0055] It should be noted that, as mentioned above, when the annular pressure sensor 1104 can detect that the pressure on the sawtooth ring 1105 is too large, the first motor 1201 works to drive the worm 1202 to rotate, the rotation of the worm 1202 can drive the worm wheel 1205 to rotate, the rotation of the worm wheel 1205 can drive the rotating rod 1203 to rotate, the rotation of the rotating rod 1203 can drive the gear 1204 to rotate, and the rotation of the gear 1204 can drive the arc baffle 10 to move upward or upward using the toothed plate 15, so that the use position of the arc baffle 10 can be adjusted, the movement of the arc baffle 10 can drive the moving plate 1102 to move, and the movement of the moving plate 1102 can drive the sampling tube 1103 to move, so that the sampling position of the soil can be adjusted, avoiding the sawtooth ring 1105 from being subjected to a large pressure when the soil is layered sampled, thereby improving the protection of the electric push rod 1101 during sampling;

[0056] When the use position of the arc baffle 10 is adjusted, the movement of the arc baffle 10 will drive the slider 20 to slide on the guide rod 19, thereby ensuring the stability of the arc baffle 10 during the movement.

[0057] Among them, a sampling groove 16 connected to the second collecting chamber 9 is opened on the outer side of the sampling drill tube 601, and a plurality of connecting tubes 17 are arranged on the side of the arc-shaped baffle plate 10 close to the sampling groove 16. The connecting tube 17 is located in the sampling groove 16, and a plurality of rubber baffles 18 are arranged inside the connecting tube 17. The plurality of rubber baffles 18 are distributed in a circular array inside the connecting tube 17, and the end of the sampling tube 1103 away from the movable plate 1102 is slidably inserted into the interior of the connecting tube 17.

[0058] It should be noted that, as mentioned above, after the sampling drill tube 601 enters the interior of the soil, the rubber baffle 18 can be used to effectively seal the connecting tube 17, effectively preventing the soil from entering the interior of the connecting tube 17, thereby ensuring the cleanliness of the interior of the connecting tube 17 and avoiding the interference of soil impurities on subsequent soil sampling results. In addition, the rubber baffle 18 will not affect the normal movement of the sampling tube 1103, and will not affect the normal sampling of the soil.

[0059] A guide block 21 is disposed inside the sampling drill bit 602. The side of the guide block 21 away from the sampling drill bit 602 is in a slope shape, and the upper side of the guide block 21 is connected to the bottom side of the partition 7.

[0060] The cross section of the support base 1 is U-shaped. Two symmetrically distributed mounting blocks 22 are provided on one side of the support base 1 . A moving roller 23 is rotatably provided on the mounting block 22 .

[0061] It should be noted that, as described above, when the sampling drill bit 602 enters the soil, the sloped side of the guide block 21 is used so that the soil can be more easily guided along the slope into the interior of the sampling drill tube 601 during the rotation and advancement of the sampling drill bit 602, thereby ensuring smooth soil sampling.

[0062] After the soil sampling is completed, the handle on the top plate 202 can be pulled to rotate the support base 1. At this time, the movable roller 23 is in contact with the ground and the support base 1 is away from the ground. The movable roller 23 is used to facilitate the movement and transfer of the device.

[0063] Example 2

[0064] like Figures 10 to 16 As shown, the present invention discloses an engineering geological survey sampling device, a plurality of grooves 24 are provided on the outer side of a sampling tube 1103, a soil breaking mechanism 25 is provided between the plurality of grooves 24, the soil breaking mechanism 25 comprises a spring 2501 provided in the groove 24, a same soil breaking block 2502 is provided at one end of two corresponding springs 2501 away from the inner wall of the groove 24, and the two soil breaking blocks 2502 are hinged;

[0065] An air pump 26 is provided on one side of the movable plate 1102 away from the sampling tube 1103, an air outlet pipe 27 is provided at the air outlet end of the air pump 26, a circular groove 28 is provided on the outer side of the sampling tube 1103, an air bag 29 is provided in the circular groove 28, a connecting pipe 30 is provided at one end of the air bag 29, and the end of the connecting pipe 30 away from the air bag 29 is connected to the air outlet pipe 27

[0066] It should be noted that, as mentioned above, when the annular pressure sensor 1104 can detect that the pressure on the sawtooth ring 1105 is too large, the movable plate 1102 needs to be moved to drive the sampling tube 1103 to move. At this time, the air pump 26 works to transport gas into the outlet pipe 27, and the gas enters the interior of the airbag 29 through the connecting pipe 30. Then the airbag 29 will gradually expand to squeeze the two soil-breaking blocks 2502. After being squeezed, the soil-breaking blocks 2502 will move and stretch the spring 2501, so that the two soil-breaking blocks 2502 can be tilted. When the sampling tube 1103 moves, the soil-breaking blocks 2502 can be used to break the soil layer more conveniently, which greatly reduces the squeezing force on the sampling tube 1103.

[0067] After the sampling tube 1103 is moved to a suitable position, the air pump 26 stops working, and then the elastic force of the spring 2501 can be used to pull the soil-breaking block 2502 back to its original position, which will not affect the subsequent continued use.

[0068] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
