Description

Technical Field

[0001] The present invention relates to the technical field of undisturbed soil collection, and in particular to an undisturbed soil specimen collection device and an operating method thereof. Background Art

[0002] Original soil specimens are of great significance in soil science research. They can preserve the original state of the soil to the greatest extent, including the structure of the soil and the physical characteristics of the soil, such as color, texture, structure, porosity, etc. These characteristics should not change as much as possible during the collection and production process.

[0003] After searching, the Chinese patent with publication number CN115561018A discloses a convenient device for collecting original soil, including a handle rod, a drill body, a connecting valve, a cutting drill bit and a bulldozer body. The handle rod is arranged horizontally, the drill body is arranged vertically below the handle rod, and the handle rod is fixedly connected to the drill body. An internal thread is arranged in the lower end tube of the drill body, and the bulldozer body is arranged below the drill body. The bulldozer body is composed of a screw rod, a support body and a bulldozer disc from top to bottom. The drill body is threadedly connected to the screw rod through an internal thread. The cutting drill bit is composed of a joint pipe, a drill pipe and a serrated blade from top to bottom. The cutting drill bit is connected to the bulldozer body through a connecting valve. The present invention is used for collecting original soil samples; however, the above scheme still has the following shortcomings when actually used:

[0004] In the complex operation of collecting deep soil in its original state, in order to ensure the integrity and representativeness of soil samples, it is often necessary to use professional sampling drills to operate. However, after the sampling tube is successfully inserted and collects valuable deep soil samples, the resistance of the soil to the sampling tube increases due to the large sampling depth. It is often difficult to pull it out smoothly and safely by manual force alone. This not only consumes a lot of manpower and time, but may also cause the sampling tube to tilt, get stuck or suddenly released during the extraction process due to improper operation, thereby squeezing, damaging or contaminating the soil sample in the sampling tube, seriously affecting the integrity of the sample and the sampling efficiency.

[0005] Therefore, the present application provides an original soil sample collection device and an operating method thereof. Summary of the invention

[0050] Preferably, the transmission block is arranged in an arc shape, and the transmission block has the same thickness as the semicircular plate.

[0051] Preferably, a method for collecting undisturbed soil samples comprises the following steps:

[0052] Step 1: transport the bottom plate and the vertical plate to the place of use and set them up. After the setting up is completed, the sampling drill can be installed between the guide block, and then the sampling tube and the sampling drill can be connected. After the connection is completed, the sampling drill is opened to collect the original soil sample through the sampling tube. After the collection is completed, the sampling drill is separated from the sampling tube, and then the sampling drill is taken out of the guide block and placed aside, and the rotating seat is rotated to rotate the clamping plate to a horizontal state. At this time, the clamping plate can be located on the outer wall of the top of the sampling tube, and the adjusting screw is rotated to move the two adjusting clamping plates to achieve a firm clamping of the top of the sampling tube;

[0053] The cam is then pulled back and the guide roller is reeled in place to allow the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move forward and backward, thereby allowing the guide roller to move backward and forward ...

[0054] Step three: When the winding roller rotates to drive the slider and the sampling tube to move, the transmission block at the end of the winding roller can contact the semicircular plate in turn and drive the semicircular plate when it rotates. Under the action of the supporting spring, the transmission shaft can slide back and forth along the penetration point with the vertical plate. During the reciprocating sliding of the transmission shaft, the end away from the semicircular plate can hit the knocking plate in an orderly manner. Under the action of the torsion spring, the knocking plate can reciprocate along the mounting frame (105), thereby knocking the sampling tube through the knocking head, so that the sampling tube can be separated from the soil more quickly. After the sampling tube is taken out of the soil, the original soil sample in the sampling tube can be taken out and collected.

[0055] Beneficial effects of the present invention:

[0056] 1. This original soil specimen collection device realizes labor-saving lifting of the sampling tube by setting a pulling component and a sorting component, utilizing a pulley group composed of a movable pulley and a fixed pulley, and combining with the rotation of a winding roller, which not only reduces the labor intensity of the staff, but also improves the sampling efficiency, making the sampling process smoother. At the same time, the rotation of the reciprocating screw drives the swing block to slide back and forth along the guide rod, ensuring the uniform winding of the connecting cable on the winding roller, avoiding cable disorder, providing convenience for subsequent use, and extending the service life of the equipment.

[0057] 2. This original soil sample collection device is provided with a knocking assembly. When it is subjected to the impact force of the transmission shaft, the knocking plate will reciprocate along the mounting frame, and the knocking head at the end thereof will accurately hit the outer wall of the sampling tube, which not only helps to destroy the tight connection between the sampling tube and the soil due to suction or adhesion, but also can vibrate and loosen the soil around the sampling tube to a certain extent, making it easier for the sampling tube to be separated from the soil. In addition, the reciprocating rotation and automatic reset function of the knocking plate ensure that each knock is powerful and uniform, avoiding unnecessary damage to the sampling tube or soil sample due to excessive knocking.

[0058] 3. This original soil specimen collection device, by setting a clamping assembly, can achieve accurate and firm clamping of the top of the sampling tube through the clamping mechanism. The flexible rotation of the adjusting screw enables the two adjusting clamping plates to fit tightly against the outer wall of the sampling tube. Even if resistance is encountered during the sampling process, the stability of the sampling tube can be ensured, which not only protects the integrity of the sampling tube and the soil sample inside it, but also enhances the safety of operation and avoids accidents caused by the sampling tube falling off.

[0075] The specific working principle of the present invention is as follows:

[0076] First, the bottom plate 1 and the vertical plate 2 can be transported to the place of use and erected. After the erection is completed, the sampling drill 5 can be installed between the guide block 4, and then the sampling tube 6 can be connected to the sampling drill 5. After the connection is completed, the staff can open the sampling drill 5 and collect the original soil sample through the sampling tube 6. After the collection is completed, the staff can separate the sampling drill 5 from the sampling tube 6, and then take out the sampling drill 5 from the guide block 4 and put it aside, and rotate the rotating seat 112 to rotate the clamping plate 113 to a horizontal state. At this time, the clamping plate 113 can be located on the outer wall of the top end of the sampling tube 6, and the staff can rotate the adjusting screw 115 to move the two adjusting clamping plates 114 to achieve a firm clamping of the top end of the sampling tube 6;

[0077] After the sampling tube 6 is fixed, the staff can rotate the handle 86 to drive the winding roller 85 to rotate. When the winding roller 85 rotates, it can drive the slider 7 to slide along the guide port 3 through the connecting cable 87, and form a pulley group under the cooperation of the movable pulley 83 and the fixed pulley 81, so that it is more labor-saving to move the slider 7 to take out the sampling tube 6. At the same time, when the handle 86 rotates, it can drive the reciprocating screw 93 to rotate through the synchronous belt and the driven wheel, and the swing block 94 is slidably connected to the guide rod 92 and is screwed with the reciprocating screw 93. Therefore, when the reciprocating screw 93 rotates, it can drive the swing block 94 to slide back and forth along the guide rod 92, so that when the winding roller 85 rewinds the connecting cable 87, the connecting cable 87 can be evenly wound on the winding roller 85, so that it can be used again to avoid confusion.

[0078] When the winding roller 85 rotates to drive the slider 7 and the sampling tube 6 to move, the transmission block 103 at the end of the winding roller 85 can contact the semicircular plate 102 in turn when it rotates and drive the semicircular plate 102. Under the action of the supporting spring 104, the transmission shaft 101 can slide back and forth along the penetration point with the vertical plate 2. During the reciprocating sliding of the transmission shaft 101, the end away from the semicircular plate 102 can hit the knocking plate 106 in an orderly manner. Under the action of the torsion spring, the knocking plate 106 can reciprocate along the mounting frame 105, thereby knocking the sampling tube 6 through the knocking head, so that the sampling tube 6 can be separated from the soil more quickly and the adhesion is reduced. After the sampling tube 6 is taken out of the soil, the original soil sample in the sampling tube 6 can be taken out and collected.

One end of the adjusting screw (115) located on the inner side of the clamping plate (113) is rotatably connected to the adjusting clamping plate (114).

9. The original soil sample collection device according to claim 8, characterized in that: The adjusting clamping plate (114) is made of elastic metal, and the opposite sides of the two adjusting clamping plates (114) are provided with anti-slip pads. The transmission block (103) is arranged in an arc shape, and the transmission block (103) has the same thickness as the semicircular plate (102).

10. A method for collecting undisturbed soil samples, characterized in that: The following steps are involved: Step 1: transport the bottom plate (1) and the vertical plate (2) to the place of use and set them up. After the setting up is completed, the sampling drill (5) can be installed between the guide block (4), and then the sampling tube (6) can be connected to the sampling drill (5). After the connection is completed, the sampling drill (5) is opened to collect the original soil sample through the sampling tube (6). After the collection is completed, the sampling drill (5) and the sampling tube (6) are separated, and the sampling drill (5) is taken out of the guide block (4) and placed aside, and the rotating seat (112) is rotated so that the clamping plate (113) is rotated to a horizontal state. At this time, the clamping plate (113) can be located on the outer wall of the top end of the sampling tube (6), and the adjusting screw (115) is rotated so that the two adjusting clamping plates (114) move to achieve a firm clamping of the top end of the sampling tube (6); Step 2: After the sampling tube (6) is fixed, the rotating handle (86) is rotated to drive the winding roller (85) to rotate. When the winding roller (85) rotates, the slider (7) can be driven to slide along the guide opening (3) through the connecting cable (87), and a pulley group is formed under the coordinated use of the movable pulley (83) and the fixed pulley (81), so that the slider (7) is moved to take out the sampling tube (6) more labor-saving. At the same time, when the rotating handle (86) is rotated, the reciprocating screw (93) can be driven to rotate through the synchronous belt and the driven wheel. The swing block (94) is slidably connected to the guide rod (92) and is screwed to the reciprocating screw (93). Therefore, when the reciprocating screw (93) rotates, it can drive the swing block (94) to slide back and forth along the guide rod (92), so that when the winding roller (85) rewinds the connecting cable (87), the connecting cable (87) can be evenly wound on the winding roller (85) for reuse; Step 3: When the winding roller (85) rotates to drive the slider (7) and the sampling tube (6) to move, the transmission block (103) at the end of the winding roller (85) can contact the semicircular plate (102) in turn and drive the semicircular plate (102) to drive the semicircular plate (102). Under the action of the support spring (104), the transmission shaft (101) can slide back and forth along the penetration point with the vertical plate (2). During the reciprocating sliding of the transmission shaft (101), the end away from the semicircular plate (102) can hit the knocking plate (106) in an orderly manner. Under the action of the torsion spring, the knocking plate (106) can reciprocate along the mounting frame (105), thereby knocking the sampling tube (6) through the knocking head, so that the sampling tube (6) can be separated from the soil more quickly. After the sampling tube (6) is taken out of the soil, the original soil sample in the sampling tube (6) can be taken out and collected.
