Before construction, an engineering survey is usually required to determine the foundation conditions through geological drilling and soil sampling to provide a basis for design. Among them, soil sampling is very necessary. As the basic supporting medium of the construction project, the properties of soil directly affect the stability, safety and durability of the project.

[0003] When sampling soil, the most widely used device is the spiral sampling device. The motor drives the auger to rotate, and the drill bit cuts into the soil. The spiral blades use the centrifugal force and thrust of the rotation to transport the soil to the placement tube at the top. The placement tube is then opened to pour out the soil for detection and analysis.

When the sampling lifting and adjusting component drives the spiral sampler 1 to rise or fall, the soil receiving and translation component drives the sampling box 4 to move forward or away from the spiral sampler 1 accordingly through the transmission component.

[0027] like Figure 2 、 Figure 5 and Figure 7 As shown, when sampling soil, the spiral sampler 1 is first installed on the sampling lifting and adjusting assembly. The installation assembly includes a mounting box 11, a mounting handle 12 and a mounting bolt 13. The sides of the crescent slider 28 and the sliding block 10 are fixedly installed with the mounting box 11, and a card slot is provided on the mounting box 11.

[0028] like Figure 2 and Figure 6As shown, after the installation is completed, start the spiral sampler 1, and then drive the spiral sampler 1 to move downward through the sampling lifting adjustment component. The sampling lifting adjustment component includes a support cover 1 5, a reciprocating screw 6, a first motor 7 and a sliding component. The support cover 1 5 is fixedly installed on the top of the mobile plate 2, and the reciprocating screw 6 is rotatably installed in the support cover 1 5, and a matching crescent slider 28 is installed on the reciprocating screw 6. The first motor 7 is installed on the support cover 1 5, and the output end of the first motor 7 is coaxially connected to the reciprocating screw 6. The sliding component is set at the top of the mobile plate 2, and the sliding component includes a support cover 2 8, a sliding rod 9 and a sliding block 10. The support cover 2 8 is fixedly installed on the mobile plate At the top of the movable plate 2, the sliding rod 9 is fixedly installed in the support cover 2 8, and the sliding block 10 is slidably installed on the sliding rod 9. Specifically, the first motor 7 is started, and the output end of the first motor 7 drives the reciprocating screw 6 to rotate in the support cover 1 5, thereby driving the crescent slider 28 to move on the reciprocating screw 6. Under the connection of the mounting box 11, the mounting handle 12 and the spiral sampler 1, the sliding block 10 at the other end is synchronously driven to rise and fall on the sliding rod 9. Because the spiral sampler 1 is located at the center position of the through slot of the movable plate 2, and the spiral sampler 1 is located above the through slot of the movable plate 2, the threaded sampler moves downward and contacts the ground through the through slot of the movable plate 2 to take soil.

[0029] like Figure 3 As shown, when the spiral sampler 1 is driven to move downward, the soil-connecting translation assembly can be driven to move through the transmission assembly, so that the sampling box 4 can move horizontally on the mobile plate 2. The soil-connecting translation assembly includes a support frame 14, a rotating shaft 15, a driving gear 16 and a driving rack 17. The support frame 14 is fixedly mounted on the top of the mobile plate 2, and the rotating shaft 15 is rotatably mounted on the support frame 14. The driving gear 16 is fixedly mounted on one end of the rotating shaft 15. The driving rack 17 is fixedly mounted on the side of the sampling box 4, and the driving gear 16 is meshed with the driving rack 17. The transmission assembly includes a support frame 2 18, a transmission shaft 19 and a driving assembly. The support frame 2 18 is fixedly mounted on the top of the movable plate 2, the transmission shaft 19 is rotatably mounted on the support frame 2 18, the driving assembly is arranged on the transmission shaft 19, the driving assembly includes a transmission gear ring 1 20, a transmission gear 1 21, a transmission gear ring 2 22 and a transmission gear ring 3 23, the transmission gear ring 1 20 is fixedly mounted on the reciprocating screw 6, the transmission gear 1 21 is fixedly mounted on one end of the transmission shaft 19, and the transmission gear ring 1 20 and the transmission gear 1 21 are meshed with each other, the transmission gear ring 2 22 is fixedly mounted on the other end of the transmission shaft 19, the transmission gear ring 3 23 is fixedly mounted on the other end of the rotating shaft 15, and the transmission gear ring 2 22 is meshed with the transmission gear ring 3 23.

[0030] Specifically, when the reciprocating screw 6 rotates, it can drive the transmission gear ring 1 20, the transmission gear ring 1 20 drives the transmission gear 1 21 to rotate, the transmission gear 1 21 drives the transmission shaft 19 to rotate, the transmission shaft 19 drives the transmission gear ring 2 22 to rotate, the transmission gear ring 2 22 drives the transmission gear ring 3 23 to rotate, the transmission gear ring 3 23 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the driving gear 16 to rotate, the driving gear 16 drives the driving rack 17 meshing therewith to move, the driving rack 17 drives the sampling box 4 to move, and under the spiral sampler 1 When the spiral sampler 1 moves, it drives the sampling box 4 to move backward. When the spiral sampler 1 finishes taking soil and moves upward, the sampling box 4 moves forward synchronously to the bottom of the spiral sampler 1 to collect soil. When taking soil, because the top of the movable plate 2 is detachably installed with a protective cover 26, and the transmission gear ring 22 and the transmission gear ring 3 23 are located in the protective cover 26, the protective cover 26 can protect the engagement between the transmission gear ring 22 and the transmission gear ring 3 23, and the transmission gear ring 1 20 and the transmission gear 1 21 are located in the support cover 1 5, and the support cover 1 5 can play a protective role.

[0031] like Figure 4 As shown, when the sampling box 4 is moved close to the spiral sampler 1, the soil taken out can be collected by the storage component. The soil storage component includes a fixed plate 27, a soil storage box 24 and a partition plate 25. The fixed plate 27 is fixedly installed in the sampling box 4, and a plurality of placement grooves are opened on the top of the fixed plate 27. The soil storage box 24 is provided with a plurality of soil storage boxes 24. The plurality of soil storage boxes 24 are placed in the placement grooves of the fixed plate 27. A partition plate 25 is fixedly installed in the soil storage box 24. The partition plate 25 divides the soil storage box 24 into two cavities. Specifically, first, one of the soil storage boxes 24 is placed in the sampling box 4. The soil storage box 24 is placed in the middle placement groove of the fixed plate 27. After the first cavity of the soil storage box 24 is located below the spiral sampler 1, it stops. The soil storage device of the spiral sampler 1 is opened, and the soil falls into the first cavity. If soil sampling is carried out at another place, after the sampling is completed, the sampling box 4 can continue to move forward so that the soil taken out from another position falls into the second cavity. If the first soil storage box 24 is full, it is moved to the placement groove at another position of the fixed plate 27, and another new soil storage box 24 is placed in the placement groove at the middle position of the fixed plate 27.

[0032] Working principle: When sampling the soil, first place the two mounting handles 12 in the slots of the two mounting boxes 11, and then thread the mounting bolts 13 into the threaded holes on the sides of the mounting handles 12 and the mounting box 11, so as to fix the spiral sampler 1. After the installation is completed, start the spiral sampler 1 and start the first motor 7 at the same time. The output end of the first motor 7 drives the reciprocating screw 6 to rotate in the support cover 5, thereby driving the crescent slider 28 to move on the reciprocating screw 6. When the mounting handle 12 is connected to the spiral sampler 1, the sliding block 10 at the other end is synchronously driven to rise and fall on the sliding rod 9, so that the threaded sampler moves down and contacts the ground through the slot of the moving plate 2 to take soil. At this time, when the reciprocating screw 6 rotates, it can drive the transmission gear ring 1 20, the transmission gear ring 1 20 drives the transmission gear 1 21 to rotate, the transmission gear 1 21 drives the transmission shaft 19 to rotate, the transmission shaft 19 drives the transmission gear ring 2 22 to rotate, the transmission gear ring 2 22 drives the transmission gear ring 3 23 to rotate, and the transmission gear ring The three 23 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the driving gear 16 to rotate, and the driving gear 16 drives the driving rack 17 meshing with it to move, and the driving rack 17 drives the sampling box 4 to move. When the spiral sampler 1 moves down, it drives the sampling box 4 to move backward. When the spiral sampler 1 finishes taking soil and moves up, the sampling box 4 moves forward synchronously to the bottom of the spiral sampler 1 to collect soil. When collecting soil, one of the soil storage boxes 24 is placed in the placement groove in the middle of the fixed plate 27 of the sampling box 4. When the first cavity 24 is located below the spiral sampler 1 and stops, the soil storage device of the spiral sampler 1 is opened, and the soil falls into the first cavity. If soil sampling is carried out at another place, after the sampling is completed, the sampling box 4 can continue to move forward, so that the soil taken out from another position falls into the second cavity. If the first soil storage box 24 is full, it is moved to a placement slot at another position of the fixed plate 27, and another new soil storage box 24 is placed in the placement slot at the middle position of the fixed plate 27.
