Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, specifically to a geotechnical engineering exploration and soil sampling device. Background Technology

[0002] In existing geotechnical engineering, the soil sampling process usually involves pushing a cart into the area, then using a lifting mechanism to move the sampling cylinder downwards and rotate it. This causes the cylinder to break through the soil layer and gradually penetrate deeper into it, allowing some soil to enter. The lifting mechanism then moves the cylinder upwards again to carry the soil out, thus completing the soil sampling. Personnel then use a hammer to tap the sampling cylinder, reducing the soil's adhesion and causing it to fall out for collection. After collection, personnel use a water pipe inserted into the sampling cylinder to clean the inner wall, facilitating future soil collection.

[0003] Although the above equipment can clean the soil sampling tube, since the soil sampling tube is a whole unit, personnel cannot carefully observe whether there is soil residue on the inner wall of the soil sampling tube during the cleaning process, which will affect the next sampling work. Utility Model Content

[0004] In view of this, the present invention provides a soil sampling device for geotechnical engineering exploration. The present invention allows personnel to open the two semi-circular blocks (one and two) that are attached together, and indirectly check the soil sampling situation of the two semi-circular blocks. At the same time, it facilitates the subsequent cleaning of the two semi-circular blocks, which is convenient for subsequent soil sampling work.

[0005] To solve the above-mentioned technical problems, this utility model provides a soil sampling device for geotechnical engineering exploration, including a fixed plate. A chute and a guide groove are respectively provided on the fixed plate. A support plate is slidably arranged in both the chute and the guide groove. A soil sampling assembly is provided at the bottom of the support plate. The soil sampling assembly includes a semi-circular block one and a semi-circular block two respectively disposed on the bottom of the support plate. The semi-circular block one and the semi-circular block two are fitted together. Drill sleeves are threaded onto the tail ends of the semi-circular blocks one and two, and fixing sleeves are threaded onto the top ends of the semi-circular blocks one and two. The fixing sleeves are installed at the bottom of the support plate by fasteners. That is, personnel first move the fixed plate to the exploration and soil sampling area. The drill bit is inserted into the soil layer of the area, and then the support plate slides down on the chute and guide groove, allowing the two semi-circular blocks to enter the soil layer. Some soil enters the semi-circular blocks, and the support plate moves within the chute and guide groove to remove the soil. Then, by releasing the fixing limit of the fixing component on the fixing sleeve, the personnel can rotate and disassemble the drill sleeve and fixing sleeve, and then open the semi-circular blocks to facilitate the removal of the soil. This also facilitates the cleaning of the semi-circular blocks, making it convenient for the next soil removal operation.

[0006] The soil sampling assembly also includes two threaded holes 1 on the outer arc surface of the drill sleeve and the fixing sleeve. Threaded holes 2 are provided on the outer arc surface of both ends of the semi-arc block 1 and the semi-arc block 2. The threaded holes 2 are provided in correspondence with the threaded holes 1. Fixing bolts 1 are threaded into both the threaded holes 1 and the threaded holes 2. That is, fixing bolts 1 are inserted into the threaded holes 1 and the threaded holes 2, so as to fix the two ends of the semi-arc block 1 and the semi-arc block 2 respectively by the drill sleeve and the fixing sleeve.

[0007] The fastener also includes a limiting block set on the top of the fixed sleeve, the limiting block is provided with a threaded hole three, a drive cylinder is rotatably set on the bottom of the support plate, a groove is provided on the drive housing, the limiting block is located in the groove, a threaded hole four is provided on the outer arc surface of the drive cylinder, and a fixing bolt two is provided on the internal threads of the threaded hole three and the threaded hole four; that is, the limiting block is inserted into the groove in the drive cylinder, and then the fixing bolt two is aligned with the threaded hole four and the threaded hole three and rotated to insert, thereby providing fixation for the drive cylinder and the limiting block by the fixing bolt two.

[0008] A motor is installed on the top of the support plate, and the output shaft of the motor is connected to the top of the drive cylinder; that is, the output shaft of the motor can drive the drive cylinder to rotate.

[0009] A lead screw is installed in the chute, and a sliding column is installed in the guide groove. The lead screw is connected to one end of the support plate, and the sliding column passes through one end of the support plate. That is, the rotation of the lead screw can drive the support plate to move up or down.

[0010] A second motor is installed on the top of the fixed plate. The output shaft of the second motor is connected to one end of the lead screw; that is, the second motor provides driving force for the lead screw, causing the lead screw to rotate.

[0011] The fixed plate has triangular support plates on both sides, and each triangular support plate has two fixed casters at the bottom; that is, the casters can move the triangular support plates, thus carrying the fixed plate.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. By fitting semi-circular blocks one and two together in the soil sampling assembly, it is easy to open semi-circular blocks one and two after soil sampling is completed, so that personnel can clean semi-circular blocks one and two, thus facilitating the next soil sampling.

[0014] 2. First, the two semi-circular blocks are fitted together. Then, the two ends of the semi-circular blocks are rotated and installed through the drill sleeve and the fixing sleeve, respectively. The fixing bolt 1 rotates and enters the threaded hole 1 on the drill sleeve and the fixing sleeve, and the fixing bolt 1 continues to rotate, thus entering the threaded hole 2 on the semi-circular blocks 1 and 2 again. This achieves a firm fixation of the semi-circular blocks 1 and 2, thereby preventing loosening when the drill sleeve rotates in contact with the ground. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4 As shown: This embodiment provides a soil sampling device for geotechnical engineering exploration, including a fixed plate 100. The fixed plate 100 is provided with a sliding groove 102 and a guide groove 104. A support plate 106 is slidably disposed within both the sliding groove 102 and the guide groove 104, allowing the support plate 106 to slide up and down within them. A soil sampling assembly 200 is disposed at the bottom of the support plate 106. The soil sampling assembly 200 includes a semi-circular block 1 204 and a semi-circular block 205 respectively disposed on the bottom of the support plate 106. The semi-circular block 1 204 and the semi-circular block 205 are fitted together. Drill sleeves 203 are threaded onto the tail ends of the semi-circular blocks 1 204 and 205. The top thread of block 205 is provided with a fixing sleeve 201. By rotating the fixing sleeve 201 and the drill sleeve 203, the fixing sleeve 201 and the drill sleeve 203 can be rotated, thereby separating them from the two sides of the semi-circular block 1 204 and the semi-circular block 205. This makes it easier for personnel to open the fitted semi-circular block 1 204 and the semi-circular block 205, indirectly checking the soil removal situation of the semi-circular block 1 204 and the semi-circular block 205. It also facilitates the subsequent cleaning of the semi-circular block 1 204 and the semi-circular block 205, which is convenient for subsequent soil removal work. The fixing sleeve 201 is installed at the bottom of the support plate 106 through the fastener 300, so the support plate 106 provides support for the fixing sleeve 201.

[0025] Soil extraction component 200 Figure 2 As shown,

[0026] The soil sampling assembly 200 also includes two threaded holes 1 on the outer arc surfaces of the drill sleeve 203 and the fixing sleeve 201, and threaded holes 2 on the outer arc surfaces of both ends of the semi-arc block 1 204 and the semi-arc block 205. The threaded holes 2 correspond to the threaded holes 1. Fixing bolts 1 206 are threaded into both the threaded holes 1 and 2, so that the fixing bolts 1 206 can be rotated and enter the threaded holes 1 and 2. This allows the drill sleeve 203 and the fixing sleeve 201 to be fixed to the semi-arc block 1 204 and the semi-arc block 205 respectively, while avoiding the drill sleeve 203 slipping or loosening with the semi-arc block 1 204 and the semi-arc block 205 when drilling for soil sampling.

[0027] Fixed sleeve 201 Figure 3 As shown,

[0028] The fastener 300 also includes a limiting block 302 disposed on the top of the fixed sleeve 201. The limiting block 302 is fixedly installed on the fixed sleeve 201 by welding. The limiting block 302 is provided with a threaded hole three. A drive cylinder 301 is rotatably disposed on the bottom of the support plate 106. The drive cylinder 301 is installed on the bottom of the support plate 106 and can rotate. A groove 304 is provided on the drive housing. The limiting block 302 is located in the groove 304. The groove 304 on the drive housing provides torque to the limiting block 302, so that the fixed sleeve 201 below the limiting block 302 rotates. A threaded hole four is provided on the outer arc surface of the drive cylinder 301. The internal threads of the threaded hole three and the threaded hole four are provided with a fixing bolt two 303.

[0029] A motor 202 is provided on the top of the support plate 106, and the output shaft of the motor 202 is connected to the top of the drive cylinder 301.

[0030] The output shaft of motor 202 can drive the drive cylinder 301 to rotate, which indirectly allows the drive cylinder 301 to carry the fixed sleeve 201 to rotate, so that the fixed sleeve 201 drives the drill sleeve 203 below to rotate, so that the soil enters the semi-circular block 204 and the semi-circular block 205, thereby completing the soil collection work.

[0031] 105 lead screw Figure 1 As shown,

[0032] A lead screw 105 is provided in the slide groove 102, and the lead screw 105 can rotate in the slide groove 102. A sliding column 101 is provided in the guide groove 104, and the sliding column 101 is fixedly installed in the guide groove 104 by welding. The lead screw 105 is connected to one end of the support plate 106, and the sliding column 101 passes through one end of the support plate 106.

[0033] A second motor 103 is provided on the top of the fixed plate 100. The output shaft of the second motor 103 is connected to one end of the lead screw 105. The output shaft of the second motor 103 can drive the lead screw 105 to rotate.

[0034] Driven by motor 2 103, the output shaft of motor 2 103 can rotate the lead screw 105, so that the external thread on the lead screw 105 meshes with the internal thread of the support plate 106, thereby driving the support plate 106 to slide up and down.

[0035] Triangular support plate 107 Figure 1 As shown,

[0036] The fixed plate 100 is provided with triangular support plates 107 on both sides. Each of the triangular support plates 107 has two fixed casters 108 at its bottom. The triangular support plates 107 are fixedly installed on the fixed plate 100 by welding, so that the casters 108 can carry the fixed plate 100 to move. At the same time, the casters 108 have a fixing device that can stop the casters 108 from rotating.

[0037] Working principle;

[0038] First, the fixed caster wheel 108 carries the triangular support plate 107 to the area where soil needs to be extracted. Then, the drill sleeve 203 contacts the ground of the area to be drilled. Motor 1 202 drives the drive cylinder 301 to rotate, causing the drill sleeve 203 below the drive cylinder 301 to rotate. Thus, the drill sleeve 203 can break the soil layer. Then, motor 2 103 drives the lead screw 105 to rotate, causing the support plate 106 to carry the drill sleeve 203 downward, so that the soil enters the semi-circular block 1 204 and semi-circular block 2 205, thus completing the soil extraction work.

[0039] After soil removal is completed, stop the rotation of motor 1 (202). Then, motor 2 (103) drives screw 105 to rotate, causing screw 105 to move support plate 106 upward, thereby carrying out semi-circular blocks 1 (204) and 2 (205). Then, by rotating fixing bolt 2 (303), fixing bolt 2 (303) is disengaged from the limiting block 302 and drive sleeve on fixing sleeve 201, allowing fixing sleeve 201 to be removed. Then, by rotating fixing bolt 1 (206), fixing bolt 2 (205) is removed. 6. The fixing sleeve 201 and the drill sleeve 203 are respectively released from fixing the semi-circular block 1 204 and semi-circular block 205. Then, by rotating the fixing sleeve 201 and the drill sleeve 203, the fixing of the semi-circular block 1 204 and semi-circular block 205 is released, making it easier for personnel to separate the semi-circular block 1 204 and semi-circular block 205. This facilitates the removal of soil and the cleaning of the inside of the semi-circular block 1 204 and semi-circular block 205, thus facilitating the next soil removal operation.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
