The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0031] In addition, for better illustration of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0032] Please refer to Figures 1 to 11 , in the embodiment of the present invention, a geological content drilling sampling device for geological survey and exploration can automatically sample soils at different depths and maintain continuous operation.

[0033] The sampling device includes a base 1 and a receiving frame 2 fixedly installed on the base 1. A transfer cylinder 4 is rotatably arranged on the receiving frame 2. An adjusting rod 5 is arranged along the axial direction of the transfer cylinder 4 and is slidably connected to the transfer cylinder 4. When the adjusting rod 5 rotates and moves downward, it can control a sampling rod 6 arranged at one end of the adjusting rod 5 to perform sampling work. It further includes a reciprocating adjusting member symmetrically arranged on the receiving frame 2. The reciprocating adjusting member is connected to the adjusting rod 5 and controls the upward movement height of the adjusting rod 5. An intermittent driving member is arranged on the base 1 and is respectively connected to the transfer cylinder 4 and the reciprocating adjusting member. When the reciprocating adjusting member makes an adjustment, a flushing mechanism arranged on the receiving frame 2 flushes the inside of the sampling rod 6.

[0034] Specifically, when drilling a hole in a specified area, the intermittent driving member is started to work. When the intermittent driving member works, it controls the transfer cylinder 4 to rotate and move downward, so as to drive the sampling rod 6 to descend and drill a hole in the rock surface. During the drilling process, powder and fine particles enter the inner cavity of the sampling rod 6. After descending to a certain depth, the sampling rod 6 resets, and the rising height changes during the resetting. At the same time, the reciprocating adjusting member adjusts the upward movement of the adjusting rod 5 to ensure that the sampling rod 6 can automatically change the descending depth during the next sampling, so as to complete the sampling work at different rock layer depths, and the descending depths of two adjacent sampling operations are the same, further improving the accuracy of sampling at different rock layer depths.

[0035] As a further solution of the present invention, please refer to Figure 3 and Figure 4 , a pushing component for pushing the sampling rod 6 is arranged in the transfer cylinder 4. The pushing component includes a limiting cylinder 3 fixedly installed on the receiving frame 2. An inner push rod 7 rotatably connected to the transfer cylinder 4 is arranged along the axial direction of the limiting cylinder 3. One end of the sampling rod 6 is inserted into the inner push rod 7 and has an external thread, and the external thread is threadedly connected to the inner push rod 7.

[0036] Preferably, at least one set of strip-shaped grooves is formed in the transfer cylinder 4, and strip-shaped blocks slidably matched with the strip-shaped grooves are arranged on the adjusting rod 5.

[0037] When the intermittent driving member is started to work, it controls the transfer cylinder 4 to rotate. Under the limiting action of the strip-shaped grooves and the strip-shaped blocks, the adjusting rod 5 and the sampling rod 6 are driven to rotate synchronously. Under the driving of the reciprocating adjusting member, the adjusting rod 5 moves downward relative to the transfer cylinder 4 and drives the inner push rod 7 to move downward synchronously. When the sampling rod 6 rotates relative to the inner push rod 7, under the action of the thread, when the transfer cylinder 4 rotates and moves downward, the sampling rod 6 moves downward and rotates synchronously, and the sampling rod 6 moves downward relative to the transfer cylinder 4, so as to realize the drilling sampling work of the sampling rod 6 on rocks at different depths.

[0038] As a further solution of the present invention, the reciprocating adjusting member includes: A first driven wheel 11. A first lead screw 20 is rotatably provided on the receiving frame 2. A threaded sleeve 19 that is rotatably connected to the first driven wheel 11 is threadedly connected to the first lead screw 20, and the threaded sleeve 19 is slidably connected to a limiting plate 21 fixedly provided on the receiving frame 2; A second driven wheel 12. A guide rail groove 201 is formed on the receiving frame 2. A slider 13 that is rotatably connected to the first driven wheel 11 is slidably provided in the guide rail groove 201, and a spring 14 is abutted between the slider 13 and the end of the guide rail groove 201; A driving wheel 10 is rotatably provided on the receiving frame 2, and the driving wheel 10 is respectively connected to the first driven wheel 11 and the second driven wheel 12 through a transmission belt 15. A convex column 1501 is provided on the transmission belt 15, and when rotating, it can control a lifting assembly connected to the connecting rod 5 to perform a reciprocating lifting action.

[0039] The lifting assembly includes a movable plate 16. The movable plate 16 is rotatably connected to the connecting rod 5 through a connecting hoop 9. A first chute 1601 that is slidably connected to the convex column 1501 is provided on the movable plate 16; A guide rod 18 is further included. The guide rod 18 is slidably connected to the movable plate 16.

[0040] Preferably, a bearing 17 is provided on the connecting rod 5, and the connecting hoop 9 is sleeved on the bearing 17 to realize the rotational connection between the connecting hoop 9 and the connecting rod 5.

[0041] Specifically, when the intermittent driving member works, it controls the driving wheel 10 and the transfer cylinder 4 to rotate simultaneously. When the driving wheel 10 rotates, under the transmission of the transmission belt 15, the first driven wheel 11 and the second driven wheel 12 rotate synchronously. When the driving wheel 10 rotates one circle, the convex column 1501 drives the movable plate 16 to complete a set of reciprocating actions. When the transmission belt 15 rotates, the convex column 1501 thereon exerts extrusion on the movable plate 16, and with the guiding action of the guide rod 18, the reciprocating lifting action of the movable plate 16 is realized. When the movable plate 16 moves, it drives the transfer cylinder 4 to move synchronously, so as to realize the requirement of the sampling rod 6 to move downward and rotate at the same time.

[0042] As a further solution of the present invention, please refer to Figure 8 and Figure 9 , the intermittent driving member includes a second lead screw 26 rotatably provided on the base 1. The second lead screw 26 is driven to rotate by a motor 27 fixedly installed on the base 1. A driving ring 25 is threadedly connected to the second lead screw 26; It further includes a first transmission shaft 22, a second transmission shaft 23 and a third transmission shaft 24 rotatably arranged on the receiving frame 2. Three collar rings are also arranged on the driving ring 25, which are respectively sleeved on the first transmission shaft 22, the second transmission shaft 23 and the third transmission shaft 24.

[0043] The flushing mechanism includes a water storage tank 43 fixedly arranged on the receiving frame 2. A piston 45 is hermetically and slidably arranged in the water storage tank 43. A movable shaft 44 is arranged along the axial direction of the piston 45, and the movable shaft 44 is controlled to move by a reciprocating pushing member arranged on the receiving frame 2.

[0044] The reciprocating pushing member includes a driving rod 40 rotatably arranged on the receiving frame 2. A driving disk 41 is arranged on the driving rod 40, and an eccentric column 4101 is arranged at an eccentric position of the driving disk 41; It further includes a movable connecting rod 42 slidably arranged on the receiving frame 2. The movable connecting rod 42 is fixedly connected to the movable shaft 44. A second sliding groove 4201 for slidably connecting with the eccentric column 4101 is formed on the movable connecting rod 42.

[0045] Preferably, a storage groove 8 in a circular ring structure is arranged on the base 1. The storage groove 8 is arranged along the axial direction of the sampling rod 6. Wherein, a drill bit 601 for drilling rocks is arranged at the end of the sampling rod 6. A plurality of through holes are arranged along the radial direction of the drill bit 601. When the water storage tank 43 flushes water into the sampling rod 6, the fine rock particles in the sampling rod 6 flow out from the through holes and are discharged into the storage groove 8 to be collected.

[0046] Preferably, a first limiting groove 2201 is formed on the first transmission shaft 22. The first limiting groove 2201 is divided into multiple sections of A-thread grooves and B-horizontal grooves. A second limiting groove 2301 is formed on the second transmission shaft 23. The second limiting groove 2301 is divided into multiple sections of C-horizontal grooves and D-thread grooves. A third limiting groove 2401 is formed on the third transmission shaft 24. The third limiting groove 2401 is divided into multiple sections of E-thread grooves and F-horizontal grooves. Wherein, a first ball, a second ball and a third ball for slidably cooperating with the first limiting groove 2201, the second limiting groove 2301 and the third limiting groove 2401 are respectively arranged in the three collar rings.

[0047] Specifically, when the motor 27 is started, the output shaft of the motor 27 is fixedly connected to the second screw rod 26, so that when the output shaft rotates, the second screw rod 26 is driven to rotate synchronously, and when the second screw rod 26 rotates, the drive ring 25 is driven to make a linear motion in a direction parallel to the axis of the second screw rod 26. In the initial state, the first ball is located in the A thread groove, the second ball is located in the C horizontal groove, and the third ball is located in the E thread groove. When the drive ring 25 moves, the first ball and the third ball squeeze the first transmission shaft 22 and the third transmission shaft 24, so that the first transmission shaft 22 and the third transmission shaft 24 rotate, so as to realize the rotation of the sampling rod 6 and the sampling rod 6 is synchronous. The sampling rod 6 moves downward step by step, wherein when the sampling rod 6 moves downward to the end of the stroke, the first ball is still in the A thread groove, and the third ball moves to the F horizontal groove, so that the sampling rod 6 is reset and does not rotate when it moves upward. When the first ball and the third ball slide to the B horizontal groove and the F horizontal groove at the same time, the second ball moves to the D thread groove to realize the rotation requirement of the second transmission shaft 23. When the second transmission shaft 23 rotates, the position of the second driven wheel 12 can be adjusted, and the water in the squeezed water storage tank 43 is transported to the sampling rod 6 through the conduit 34 to realize the flushing of fine particles in the sampling rod 6 and complete the sampling work at different depths.

[0048] In the initial state, the spring 14 is in a compressed state. When the first screw rod 20 rotates, the threaded sleeve 19 is driven to move axially along the first screw rod 20, so that the position of the second driven wheel 12 changes. At this time, the pulling force of the transmission belt 15 on the first driven wheel 11 is less than the elastic force of the spring 14. Under the action of the elastic potential energy of the spring 14, the slider 13 moves upward in the guide rail groove 201. When moving upward, the position of the first driven wheel 11 changes to ensure that the transmission belt 15 always maintains a taut transmission state. When the first driven wheel 11 moves upward, the position of the transmission belt 15 is adjusted to drive the sampling rod 6 to move upward, and the distance that the sampling rod 6 moves upward is the length of the relative downward movement of the connecting rod 5 when the sampling rod 6 performs the sampling work in the early stage, so as to realize the change of the distance between the first driven wheel 11 and the driving wheel 10 without affecting the connection with the sampling rod 6.

[0049] As a further solution of the present invention, please refer to Figure 8 and Figure 9 The first transmission shaft 22 is rotatably connected to the first connecting shaft 30 rotatably arranged on the receiving frame 2 through the first bevel gear set 28, and the first connecting shaft 30 is rotatably connected to the driving wheel 10 through the third bevel gear set 31; The second transmission shaft 23 is rotatably connected to the first screw 20 and the third connecting shaft 36 rotatably arranged on the receiving frame 2 through the second bevel gear set 29, the third connecting shaft 36 is rotatably connected to the fourth connecting shaft 38 rotatably arranged on the receiving frame 2 through the fifth bevel gear set 37, and the fourth connecting shaft 38 is rotatably connected to the driving rod 40 through the gear set 39; The third transmission shaft 24 is rotationally connected to a second connecting shaft 33 rotatably provided on the receiving frame 2 through a fourth bevel gear set 32, and the second connecting shaft 33 is rotationally connected to the transfer cylinder 4 through a belt 35.
