DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] like Figure 1-Figure 14 As shown, the present invention provides a multifunctional surveying equipment for municipal building construction, including a base plate 1, wherein the upper end surface of the base plate 1 is provided with a connecting plate 6 which can move left and right, and side plates 10 are respectively provided on both sides of the connecting plate 6, and an L-shaped seat 18 is provided on the inner side of the two side plates 10, and a sampling barrel 37 which can rotate and move downward is provided at the lower end of the L-shaped seat 18, and a rotatable driving rod 12 is respectively provided on the outer side of the two side plates 10, and when the driving rod 12 rotates, a structure in which the sampling barrel 37 moves and flips upward can be formed, and when the driving rod 12 continues to rotate, a structure in which the sampling barrel 37 moves downward and can open the sampling barrel 37 can be formed.

[0034] like Figure 1-Figure 4 As shown, the bottom plate 1 is used to support the entire device, and rotatable moving wheels 2 are respectively provided at the four end corners of the lower end surface of the bottom plate 1. The moving wheels 2 can enable the device to reach a specified position. The moving wheels 2 are prior art and will not be described in detail. Figure 3 As shown, a plurality of evenly distributed placement grooves 7 are provided on the rear side of the upper end of the bottom plate 1, and collecting boxes 8 are placed in the placement grooves 7. When the sampling tube 37 is opened, the collecting box 8 can receive the soil sample. A plurality of partitions 9 are also provided on the inner wall of the collecting box 8.

By providing a connecting plate 6 that can move left and right, the position of the L-shaped seat 18 and the sampling tube 37 can be adjusted, that is, the soil sample can be unloaded into the collecting box 8. When the sampling tube 37 rotates and moves downward, the soil can be sampled. After the sampling is completed, the tube 37 is opened. With the cooperation of the side plate 10 and the driving rod 12, when the driving rod 12 rotates, the sampling barrel 37 can be driven to move backward to the specified position, that is, the position just above the corresponding collection box 8, and the sampling barrel 37 will flip 90 degrees to a horizontal state. When the driving rod 12 continues to rotate, the sampling barrel 37 can move downward, and the sampling barrel 37 moves outward to open, and the soil sample will fall into the collection box 8 under the action of weight, so that the soil sample inside the sampling barrel 37 is unloaded to the specified position, replacing the manual operation throughout the process. After sampling, the soil sample can be automatically unloaded, and the unloading is cleaner and more efficient, saving human resources.

[0035] The upper end surface of the base plate 1 is also fixedly connected to a first motor 3, an output end of the first motor 3 is fixedly connected to a first threaded rod 4, an outer surface of the first threaded rod 4 is threadedly connected to a first threaded seat 5 fixedly connected to a connecting plate 6, and the connecting plate 6 is slidably connected to the upper end surface of the base plate 1.

[0036] like Figure 3-Figure 4 As shown, the function of the first motor 3 is to provide rotational force for the first threaded rod 4. The motor is of existing technology and will not be described in detail. The first threaded rod 4 is rotatably connected to the upper end of the base plate 1 through a bearing seat, that is, the first threaded rod 4 is limited to rotate only, and the connecting plate 6 can be slidably connected to the upper end surface of the base plate 1 left and right, and the side plates 10 are respectively fixed on the left and right sides of the upper end surface of the connecting plate 6. When the first motor 3 is started, it can drive the corresponding first threaded rod 4 to rotate. When the first threaded rod 4 rotates, it will drive the corresponding connecting plate 6, side plate 10, etc. to move left or right through the threaded connection with the first threaded seat 5, thereby adjusting the position of the side plate 10, L-shaped seat 18, and sampling tube 37. It will not be described in detail, and the threaded connection between the first threaded rod 4 and the first threaded seat 5 has a self-locking function, that is, when the first motor 3 is not started, the corresponding connecting plate 6, side plate 10, sampling tube 37, etc. are in a stable state, so that the sampling tube 37 can work stably.

[0037] The second motors 11 are fixedly connected to the outer end surfaces of the side plates 10, and the driving rods 12 are fixedly connected to the corresponding output ends of the second motors 11. The inner end surfaces of the two side plates 10 are slidably connected with cross plates 19 on the front and rear sides, and the inner end surfaces of the two cross plates 19 are fixedly connected with a plurality of limiting guide rods 20. The L-shaped seat 18 is slidably connected to the outer surfaces of the plurality of limiting guide rods 20. The left and right end surfaces of the L-shaped seat 18 are respectively fixedly connected with the first sliding pins 14. Guide grooves matching the first sliding pins 14 are respectively provided on the side plates 10, and long key grooves matching the first sliding pins 14 are respectively provided on the driving rods 12.

[0038] like Figure 4-Figure 7 As shown, the function of the second motor 11 is to provide a rotational force for the driving rod 12, and the driving rod 12 is rotatably connected to the side plate 10 via a rotating shaft, as shown in FIG. Figure 6 As shown, the transverse plate 19 can be slidably connected to the inner end surface of the side plate 10 up and down, and the L-shaped seat 18 can be slidably connected to the outer surface of the limiting guide rod 20 forward and backward. There are at least two limiting guide rods 20, that is, the L-shaped seat 18 can be limited and supported to move forward and backward stably. Under the limitation of the L-shaped seat 18 by the transverse plate 19 and the limiting guide rod 20, the limited L-shaped seat 18 can only move up and down or forward and backward. The installation and shape of the guide groove, the first sliding pin 14, the driving rod 12, and the long key groove 13 are as shown in FIG. Figure 4As shown, by the meshing of the guide groove and the first sliding pin 14, the first sliding pin 14 can be limited to move only along the inner wall of the guide groove, and by the meshing of the first sliding pin 14 and the long key groove 13, when the driving rod 12 rotates, the first sliding pin 14 can be driven to move up and down or forward and backward along the inner wall of the guide groove; the second motor 11 is a servo motor, that is, it has a self-locking function, which can make the corresponding position of the first sliding pin 14 stable when the driving rod 12 does not rotate; the guide groove includes a short vertical groove 15, a long horizontal groove 16 and a long vertical groove 17. When the first sliding pin 14 is on the inner wall of the short vertical groove 15 or the long vertical groove 17, the driving rod 12 can rotate to drive the first sliding pin 14 to move upward or downward, and when the first sliding pin 14 is on the inner wall of the long horizontal groove 16, the driving rod 12 can rotate to drive the first sliding pin 14 to move forward or backward When the second motor 11 is started, the driving rod 12 can be rotated, and when the driving rod 12 rotates, the corresponding first sliding pin 14 can be driven to move along the inner wall of the guide groove, and the first sliding pin 14 moves upward on the inner wall of the short vertical groove 15, that is, the L-shaped seat 18 moves upward. When the first sliding pin 14 moves upward to the top end and enters the inner wall of the long horizontal groove 16, the driving rod 12 continues to rotate, which will drive the first sliding pin 14 to move horizontally backward, that is, the corresponding L-shaped seat 18 moves horizontally backward. When the first sliding pin 14 moves backward to the top end and enters the inner wall of the long vertical groove 17, the driving rod 12 continues to rotate, which will drive the corresponding first sliding pin 14 and the L-shaped seat 18 to move vertically downward. When the driving rod 12 is reversed, the first sliding pin 14, the L-shaped seat 18, etc. can be driven to return to the initial position of the front end. The principle is the same and will not be repeated here.

[0039] The upper end surface of the L-shaped seat 18 is slidably connected to two sliding seats 21, and the lower end surface of the L-shaped seat 18 is hinged with a mounting plate 24, and the sampling tube 37 is installed on the mounting plate 24. The left and right ends of the mounting plate 24 are coaxially fixed with cranks 23, and the inner walls of the upper ends of the cranks 23 are respectively fixed with second sliding pins 28. Short key grooves 22 that match the second sliding pins 28 are respectively opened on the outer end surfaces of the two sliding seats 21, and a connecting rod 26 is fixed to the inner walls of the upper ends of the two sliding seats 21. The left and right ends of the connecting rod 26 are respectively slidably connected to the side plates 10.

[0040] like Figure 5-Figure 7 As shown, the sliding seat 21 can slide forward and backward on the upper end surface of the L-shaped seat 18, the mounting plate 24 and the inner wall of the crank 23 are fixedly connected with a rotating shaft, and the outer surface of the rotating shaft is rotatably connected with a bearing seat, and the bottom end of the bearing seat is fixedly connected to the lower end surface of the L-shaped seat 18, which is equivalent to the mounting plate 24 being hinged on the lower end surface of the L-shaped seat 18, that is, when the crank 23 rotates, it can drive the mounting plate 24 to flip forward and backward. The installation and shape of the sliding seat 21, the second sliding pin 28, and the crank 23 are as shown in FIG. Figure 7 As shown, when the sliding seat 21 moves forward and backward on the L-shaped seat 18, the short key slot 22 is engaged with the second sliding pin 28 to drive the crank 23 to flip forward or backward, thereby driving the mounting plate 24 and the sampling tube 37 to flip; Figure 6 As shown, small sliders 25 are fixedly connected to the left and right end surfaces of the connecting rod 26, and the small sliders 25 are respectively connected to the inner wall of the side plate 10 for sliding up and down. That is, through the limitation of the small sliders 25 and the connecting rod 26, the sliding seat 21 can only move up and down on the inner side of the side plate 10, and cannot move forward and backward; when the L-shaped seat 18 moves up and down, the sliding seat 21 can move up and down with the L-shaped seat 18. At this time, the sliding seat 21 will not move relative to the L-shaped seat 18, that is, the corresponding crank 23, the mounting plate 24, etc. will not deflect and swing. When the L-shaped seat 18 moves forward and backward At this time, the sliding seat 21 will move relative to the L-shaped seat 18, that is, when the L-shaped seat 18 moves backward, it can drive the corresponding crank 23, the mounting plate 24, etc. to move backward. When the crank 23 moves backward, the second sliding pin 28 is engaged with the short key groove 22, which will cause the corresponding crank 23 to rotate and move backward, that is, drive the mounting plate 24 and the sampling tube 37 to flip 90 degrees to a horizontal state. When the L-shaped seat 18 moves forward, it will drive the mounting plate 24 and the sampling tube 37 to reset, even if the mounting plate 24 and the sampling tube 37 are flipped to a vertical state, which is convenient for Therefore, through the cooperation of the driving rod 12 and the first sliding pin 14, when the driving rod 12 rotates, it can drive the L-shaped seat 18, the mounting plate 24, the sampling tube 37, etc. to move upward for a short distance, so that the sampling tube 37, the mounting plate 24, etc. move upward away from the ground, the bottom plate 1 and other parts to prevent the mounting plate 24 and the sampling tube 37 from turning over. When the driving rod 12 continues to rotate to make the first sliding pin 14 enter the inner wall of the long horizontal groove 16 and move backward, the corresponding L-shaped seat 18 moves horizontally backward, and the L-shaped seat 18 moves horizontally backward again. The crank 23, the mounting plate 24, the sampling barrel 37 and the like will be driven to move horizontally backward. When the crank 23 and the second sliding pin 28 are engaged with the short key groove 22, the crank 23 and the mounting plate 24 will be flipped, so that the sampling barrel 37 will be flipped 90 degrees to a horizontal state. When the driving rod 12 continues to rotate and the first sliding pin 14 enters the inner wall of the long vertical groove 17, it will move downward again. When the first sliding pin 14, the L-shaped seat 18, the mounting plate 24, the sampling barrel 37 and the like move downward, the corresponding sampling barrel 37 will open, so that the soil sample can be poured into the collection box 8.

[0041] The front end surface of the mounting plate 24 is slidably connected to a driving plate 33, a rotatable driving pulley 30 is provided at the upper end of the driving plate 33, a driven pulley 29 connected to the driving pulley 30 is also provided at the upper end of the driving plate 33, a threaded cylinder 32 rotatably connected to the driving plate 33 is fixedly connected to the inner wall at the center of the driven pulley 29, a second threaded rod 31 is fixedly connected to the front end of the mounting plate 24, the threaded cylinder 32 is threadedly connected to the outer surface of the second threaded rod 31, a one-way transmission shaft 34 is provided at the lower end of the driving pulley 30, and a sampling cylinder 37 is fixedly connected to the lower end of the one-way transmission shaft 34.

[0042] like Figure 9-10The second threaded rod 31 is connected to the outer surface of the second threaded rod 31 and the second threaded rod 31 is connected to the inner wall of the driving plate 3 ... The flywheel mechanism of the bicycle can transmit rotational force in one direction, that is, when the driving pulley 30 rotates forward, it can drive the one-way transmission shaft 34 and the sampling barrel 37 to rotate, and when the driving pulley 30 rotates reversely, it no longer drives the one-way transmission shaft 34 and the sampling barrel 37 to rotate. The ratchet pawl mechanism belongs to the prior art and will not be described in detail. When the sampling barrel 37 is in the vertical state at the front end, the driving pulley 30 is rotated forward by starting the motor, and the sampling barrel 37 can be driven to move downward while rotating. The bottom of the sampling barrel 37 is provided with teeth to facilitate better cutting of soil sampling. When the sampling barrel 37 moves downward while rotating, the soil can be sampled. After the sampling barrel 37 moves downward to the specified position, the motor is controlled to reverse the driving pulley 30, which can drive the driven pulley 29 and the threaded barrel 32 to reverse. At this time, the sampling barrel 37 no longer rotates to prevent the internal soil from falling when the sampling barrel 37 moves upward to reset. The driving plate 33 and the sampling barrel 37 will move upward to the specified position to reset.

[0043] The front end surface of the driving plate 33 is slidably connected to two short guide rods 41, and the front end surfaces of the two short guide rods 41 are fixedly connected to a clutch seat 40. The outer surfaces of the short guide rods 41 are respectively sleeved with first springs 42 that match the clutch seat 40. The lower end of the clutch seat 40 is hinged with two first connecting rods 43. Extension plates 61 are provided at the left and right ends of the driving plate 33. The inner walls of the extension plates 61 are respectively slidably connected to square sliders 60. The inner walls of the square sliders 60 are respectively provided with pins 44. The lower end surfaces of the pins 44 are respectively fixedly connected to sleeves 35. The sampling tube 37 includes two semi-cylinders. The upper ends of the outer surfaces of the semi-cylinders are respectively fixedly connected to arcuate slide rails 36, which are respectively slidably connected to the corresponding inner walls of the sleeves 35.

[0044] like Figure 10-13As shown, the short guide rod 41 can be slidably connected to the inner wall of the driving plate 33, and can limit the clutch seat 40 to move forward and backward only on the driving plate 33. Through the hinge connection between the first connecting rod 43 and the clutch seat 40, when the clutch seat 40 is at the front end position, the corresponding two pin shafts 44 are in the innermost end state under normal conditions, that is, the two sleeve seats 35 are in the innermost end state under normal conditions, and the square slider 60 can be slidably connected to the extension plate 61 left and right, and can limit the pin shaft 44 and the sleeve seat 35 to move left and right; the installation and shape of the two semi-cylinders are as shown in FIG. Fig.11 As shown, the inner walls of the two corresponding semi-cylinders are respectively provided with a plurality of first latches 38 and first latch grooves 39. When the two semi-cylinders are contacted and closed toward the inside, the first latches 38 and the first latch grooves 39 can mesh, and prevent the two semi-cylinders from separating when the sampling barrel 37 rotates. The sliding connection between the arc-shaped slide rail 36 and the sleeve 35 is equivalent to the sampling barrel 37 being rotatably connected to the inner walls of the two sleeves 35. When the two sleeves 35 are at the innermost ends, the sampling barrel 37 can rotate on the inner wall of the sleeve 35. When the sampling barrel 37 rotates to the specified position, even if the corresponding arc-shaped slide rails 36 are respectively at the corresponding The inner wall of the sleeve 35, at this time, the two sleeves 35 move outward, which can drive the two semi-cylinders to move outward, so that the sampling tube 37 is opened, so that the soil sample inside is unloaded to the specified position; when the clutch seat 40 is squeezed to move backward, the two first connecting rods 43 can be driven to move outward, and the pin 44, the sleeve 35, etc. can be driven to move outward, so that the sampling tube 37 is opened. When the clutch seat 40 is no longer squeezed, the clutch seat 40, the first connecting rod 43, the pin 44, the sleeve 35, etc. will be reset to the initial state under the elastic force of the first spring 42, that is, the sampling tube 37 is closed again.

[0045] The inner walls of the sleeve 35 are respectively provided with engaging mechanisms that match the arc-shaped slide rail 36 , and when the two pin shafts 44 move outward, the engaging mechanisms can be opened to fix the arc-shaped slide rail 36 .

[0046] like Figure 12-13 As shown, through the provided locking mechanism, when the two pins 44 move outward to open the sampling tube 37, the corresponding locking mechanism can be opened to fix the arc-shaped slide rail 36 and the semi-cylinder, thereby preventing the arc-shaped slide rail 36, the semi-cylinder and the sleeve 35 from moving relative to each other.

[0047] The engaging mechanisms include sliding rods 51 that can move up and down, and the sliding rods 51 are slidably connected to the corresponding inner walls of the pin shafts 44. The lower ends of the sliding rods 51 are rotatably connected to U-shaped plates 45 that are slidably connected to the sleeve 35. The middle inner walls of the sleeve 35 are slidably connected to square guide rods 48. The middle inner walls of the square guide rods 48 are fixedly connected to short sliding pins 47. Short oblique grooves 46 that match the short sliding pins 47 are respectively provided on the U-shaped plates 45. Second bayonet pins 49 are respectively fixedly connected to the inner end surfaces of the two square guide rods 48. Second bayonet slots 50 that match the second bayonet pins 49 are respectively provided on the arc-shaped slide rails 36.

[0048] like Figure 13-14 As shown, the slide bar 51 passes through the inner wall of the pin shaft 44, and the slide bar 51 can move up and down and rotate on the inner wall of the pin shaft 44, that is, when the pin shaft 44 and the sleeve 35 rotate, they do not affect each other when the slide bar 51 moves up and down. The U-shaped plate 45 can be slidably connected to the inner wall of the sleeve 35 up and down. The U-shaped plate 45 is rotatably connected with the slide bar 51. When the slide bar 51 moves up and down, it can drive the U-shaped plate 45 to move up and down, and the U-shaped plate 45 and the sleeve 35 rotate without affecting the slide bar 51. The square guide rod 48 can be slidably connected to the inner wall of the sleeve 35 left and right. The installation and shape of the second bayonet 49 and the second slot 50 are as shown in FIG. Fig.13 As shown, when the square guide rod 48 moves inward, it can drive the corresponding second bayonet 49 to move inward. When the second bayonet 49 moves inward, it can engage with the second bayonet groove 50. After the second bayonet 49 engages with the second bayonet groove 50, it can limit the rotation of the arc-shaped slide rail 36, that is, fix the arc-shaped slide rail 36; when the slide bar 51 moves downward, it can drive the corresponding U-shaped plate 45 to move downward. When the U-shaped plate 45 moves downward, the engagement between the short inclined groove 46 and the short slide pin 47 can drive the short slide pin 47 and the square guide rod 48 to rotate. 8 moves inward, and when the square guide rod 48 moves inward, it can drive the corresponding second bayonet 49 to move inward and engage with the second slot 50. At this time, the engaging mechanism is opened, and the arc-shaped slide rail 36 can be locked and limited, that is, the arc-shaped slide rail 36 and the semi-cylinder are prevented from moving on the inner wall of the sleeve 35. When the slide rod 51 moves upward, it can drive the square guide rod 48 and the second bayonet 49 to move outward. After the second bayonet 49 moves outward to disengage from the second slot 50, the arc-shaped slide rail 36 is no longer limited, that is, the engaging mechanism is closed.

[0049] The upper ends of the slide bars 51 are provided with third slide pins 52 , and the front and rear sides of the upper end surface of the extension plate 61 are fixedly connected with track plates 53 , respectively. The track plates 53 are provided with track grooves matched with the third slide pins 52 .

[0050] like Figure 13-14As shown, the upper end surface of the slide bar 51 is fixedly connected with a support seat, and the third sliding pin 52 is fixedly connected to the inner wall of the support seat, which is equivalent to the third sliding pin 52 being fixedly connected to the upper end of the slide bar 51; the track groove includes a first inclined groove 54 and a first transverse groove 55. When the third sliding pin 52 is engaged with the first inclined groove 54, the third sliding pin 52 and the slide bar 51 can be driven to move downward when the third sliding pin 52 moves outward. When the third sliding pin 52 is engaged with the first transverse groove 55, the third sliding pin 52 moves outward and no longer moves upward or downward; when the clutch seat 40 moves backward, the pin shaft 44 can be driven to move outward, and the pin shaft 44 moves outward. When moving, it can also drive the corresponding sliding rod 51, the third sliding pin 52, the sleeve 35, the semi-cylinder, etc. to move synchronously outward. When the third sliding pin 52 moves outward, the first inclined groove 54 is engaged with the third sliding pin 52, and the third sliding pin 52 can be driven to move downward and outward at the same time, that is, the corresponding U-shaped plate 45 moves downward, and the second bayonet 49 moves inward and engages with the second slot 50, and the limiting arc slide rail 36 moves. When the third sliding pin 52 moves downward to the inner wall of the first transverse groove 55, the second bayonet 49 is stably engaged with the second slot 50, that is, the engaging mechanism is opened, and the sampling tube 37 is opened.

[0051] The first spur gear 58 is fixedly connected to the outer surface of the pin shaft 44, the first spur rack 59 matched with the first spur gear 58 is fixedly connected to the lower end surface of the extension plate 61, the square locking block 56 is also fixedly connected to the outer surface of the pin shaft 44, and the lower end surface of the extension plate 61 is also fixedly connected to the rail 57 matched with the square locking block 56.

[0052] like Figure 13-14 As shown, the pin 44 is rotatably connected to the inner wall of the square slider 60, that is, the pin 44 can move left and right and can rotate. When the pin 44 rotates, it can drive the corresponding sleeve 35 to rotate. The installation and shape of the rail 57, the square lock block 56, the first straight rack 59, and the first straight gear 58 are as shown in FIG. Fig.14As shown, when the square lock block 56 is engaged with the rail 57, the rotation of the pin shaft 44 and the first spur gear 58 can be restricted. When the first spur gear 58 meets the first spur rack 59, when the pin shaft 44 moves, the corresponding pin shaft 44 and the sleeve 35 can be driven to rotate under the engagement of the first spur gear 58 and the first spur rack 59; that is, when the pin shaft 44 moves from the inside to the outside, the square lock block 56 and the first spur gear 58 can be synchronously moved outward. When the square lock block 56 moves outward and disengages from the rail 57, the pin shaft 44 , the first spur gear 58 continues to move outward, the first spur gear 58 will meet the first spur rack 59. At this time, the pin shaft 44 continues to move outward, which will drive the first spur gear 58, the pin shaft 44, and the square lock block 56 to rotate 90 degrees, that is, the sleeve 35 and the semi-cylinder rotate 90 degrees. When the pin shaft 44 continues to move outward, the first spur gear 58 will be disengaged from the first spur rack 59, and the square lock block 56 will enter the outer rail 57. At this time, the square lock block 56, the pin shaft 44, the sleeve 35, and the plate semi-cylinder can be prevented from rotating; Figure 5 As shown, a U-shaped baffle 27 matching with the clutch seat 40 is fixedly connected to the lower end surface of the two side plates 10. When the driving rod 12 rotates, it can drive the corresponding first sliding pin 14, L-shaped seat 18, sampling tube 37, clutch seat 40, etc. to move, that is, under the engagement of the first sliding pin 14 and the short vertical groove 15, the first sliding pin 14 and the L-shaped seat 18 can be driven to move upward first. When the first sliding pin 14 enters the inner wall of the long horizontal groove 16, the driving rod 12 rotates. When the first sliding pin 14 enters the inner wall of the long vertical groove 17, the corresponding mounting plate 24, driving plate 33, sampling tube 37, etc. will rotate 90 degrees to a horizontal state, and the driving rod 1 When the L-shaped seat 18, the mounting plate 24, the driving plate 33, the sampling tube 37, the clutch seat 40, etc. continue to rotate, the L-shaped seat 18, the mounting plate 24, the driving plate 33, the sleeve seat 35, the sampling tube 37, etc. will be driven to move downward synchronously. When the L-shaped seat 18, the mounting plate 24, the driving plate 33, the sleeve seat 35, the sampling tube 37, etc. continue to move downward, the corresponding two pin shafts 44 will move outward, and the locking mechanism will open to limit the rotation of the arc-shaped slide rail 36 and the sampling tube 37. When the pin shaft 44 moves outward to the specified position, the two sleeve seats 35 and the semi-cylinder will be driven to move outward and flip downward, so that the opening of the semi-cylinder faces downward, thereby pouring the soil sample into the collection box 8. When the driving rod 12 rotates in the opposite direction, the L-shaped seat 18, the sampling tube 37, etc. can be driven to move forward and reset, and the corresponding pin shaft 44 will move inward under the action of gravity, that is, the sampling tube 37 is closed.

[0053] When the present invention is in use, by providing a connecting plate 6 that can move left and right, the position of the L-shaped seat 18 and the sampling tube 37 can be adjusted, that is, the soil sample can be unloaded into the collection box 8; when the sampling tube 37 rotates and moves downward, the soil can be sampled. After the sampling is completed, through the cooperation of the side plate 10 and the driving rod 12, the sampling tube 37 can be driven to move backward to a specified position, that is, the position just above the corresponding collection box 8, and the sampling tube 37 will flip to a horizontal state again. When the driving rod 12 continues to rotate, the sampling tube 37 can be moved downward, and the sampling tube 37 moves outward to open, and the soil sample will fall into the collection box 8 under the action of weight, so that the soil sample inside the sampling tube 37 is unloaded to the specified position, replacing manual operation throughout the process. After sampling, the soil sample can be automatically unloaded, and the unloading is cleaner and more efficient, saving human resources.

[0054] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
