Description

Technical Field

[0001] The present invention relates to the technical field of automated sampling, in particular to automated sampling equipment for environmental engineering project management and a method of use. Background Art

[0002] Soil sampling is the basis for assessing soil quality and health. Soil samples can be analyzed in the laboratory or on-site to obtain data and information on soil texture, chemical properties, biological characteristics, etc. These data have important application value in agriculture, environmental protection, soil improvement, soil pollution control and other fields. In environmental engineering project management, automated sampling equipment is an important technical tool. In the soil sampling work of environmental engineering project management, the soil collection cover is a key component. Its cleaning and sampling convenience have an important impact on the entire sampling process. Since the sampling cylinder of the existing device is integrated with the internal sampling rod, the external sampling cylinder cannot be removed separately after the sampling is completed, resulting in a large amount of residual soil adhering to the inner wall. It is easy to be mixed with the residual soil during the later soil sampling and collection, thereby affecting the sampling and detection efficiency of the soil. Summary of the Invention

[0005] The lifting assembly has a second drive motor, and the output end of the second drive motor is equipped with a driving turntable, the surface of the driving turntable is connected to the driven turntable through a belt drive, the bottom of the driven turntable is rotatably equipped with a threaded rod, the surface of the threaded rod is threadedly connected to a lifting threaded block, and a positioning connecting seat is fixedly installed on the right side of the lifting threaded block, and the right side of the positioning connecting seat is connected to the surface of the soil collection cover.

[0006] As a preferred solution, the positioning assembly includes a fixing seat, and tightening springs are installed on the upper and lower sides of the inner cavity of the fixing seat. The inner end of the tightening spring is fixedly installed with a positioning card seat, and an installation groove is opened inside the positioning card seat. The interior of the installation groove is clamped with an installation block, and a soil collection box is fixedly installed on the right side of the installation block. The collection part of the soil collection box is sealed and fitted with the right surface of the soil collection cover.

[0007] As a preferred solution, a compaction assembly is installed inside the soil collection box, and the compaction assembly includes a soil pressing plate, and a lifting connecting frame is fixedly installed on the upper end of the soil pressing plate. The upper end of the lifting connecting frame extends through and extends above the soil collection box and is installed with a second electric cylinder.

[0008] As a preferred solution, the second electric cylinder is located on the right side of the soil collection box, a support frame is fixedly installed on the bottom of the second electric cylinder, and the left end of the support frame is connected to the right side of the soil collection box.

[0009] As a preferred solution, a bottom support plate is installed at the lower end of the threaded rod through an embedded bearing, and the rear end of the bottom support plate is connected to the side surface of the positioning vertical plate.

[0010] As a preferred solution, a motor bearing plate is fixedly mounted on the bottom of the second drive motor. The motor bearing plate is made of high-strength material, and the other end of the motor bearing plate is welded to the back of the positioning vertical plate.

[0011] As a preferred solution, a limiting slide is fixedly installed on the outside of the lifting thread block, and a sliding limiting vertical rod is embedded in the rear end of the limiting slide, and the right side of the limiting vertical rod is connected to the side of the positioning vertical plate.

[0012] As a preferred solution, a through slot is provided inside the lower end of the positioning vertical plate, and one end of the belt connecting the driving turntable and the driven turntable is located inside the through slot.

[0013] As a preferred solution, the upper end of the soil pressing plate is conical, and a material leakage trough is provided inside the left side of the soil pressing plate and near the discharge trough.

[0014] As a preferred solution, a method for using an automated sampling device for environmental engineering project management is provided, and the specific steps are as follows:

[0015] The first step is to start the first electric cylinder and use its output end to push the driving seat to move downward. Since the driving seat cooperates with the slide rail, under the action of the first electric cylinder, the driving seat can move downward along the slide rail and simultaneously drive the first drive motor and the drill rod at the bottom to adjust the overall height;

[0016] The second step is to start the second driving motor, and its output end drives the active turntable to rotate. The active turntable rotates the driven turntable through the belt drive, and the threaded rod installed at the bottom of the driven turntable rotates clockwise, thereby driving the lifting threaded block on the surface and the positioning connection seat and soil collection cover connected thereto downward until the bottom of the soil collection cover is completely stuck on the soil surface;

[0017] In the third step, when sampling and collecting soil, the first drive motor drives the drill rod to rotate at high speed, and the first electric cylinder continues to work to drive the top plate and the connected drill rod downward through the drive seat to achieve drilling and collection of soil. Since a conveying auger is installed on the surface of the drill rod, the drilled soil can be transported upward and discharged into the soil collection box through the discharge chute for collection;

[0018] Step 4. After the soil sample is collected in the soil collection box, the second electric cylinder is started. The second electric cylinder drives the soil pressing plate to move downward through the lifting connecting frame. The upper end of the soil pressing plate is conical. This shape will not cause soil to remain on the top. The soil sample in the soil collection box can be compacted by the soil pressing plate. Since the soil collection cover and the drill rod are designed to be separated, after the soil sampling is completed, the drill rod is reset, and the second drive motor can be used to adjust the position of the soil collection cover and move it out from the outside of the drill rod to facilitate the cleaning of the inner wall and prevent residue.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention realizes automated sampling through the cooperation of the first electric cylinder, the first drive motor, the drill rod and other components, thereby improving sampling efficiency and reducing manual operation. The soil pressing plate can effectively collect and compact soil samples. The soil collection cover can be raised and lowered through the second drive motor, the active turntable, the driven turntable, the threaded rod and the lifting threaded block and other components. The device adopts a separate design between the soil collection cover and the drill rod. After the soil sampling is completed, the second drive motor can be used to adjust the position of the soil collection cover and it can be moved out from the outside of the drill rod, which is convenient for cleaning the inner wall and preventing residue. The structure is stable, ensuring the accuracy and stability of sampling.

[0021] 2. The present invention applies pressure by tightening the spring, so that the positioning card holder tightly clamps the installation block, thereby ensuring that the soil collection box is sealed and fitted with the right surface of the soil collection cover, effectively preventing soil samples from leaking during transmission, ensuring the integrity and accuracy of the samples, and providing a reliable sample source for subsequent detection and analysis. The mounting groove inside the positioning card holder and the clamping structure of the installation block make the installation and disassembly process of the soil collection box relatively simple. When the soil collection box needs to be cleaned or replaced, the operation can be performed quickly, which improves the convenience of use and maintenance efficiency of the equipment; the second electric cylinder can drive the soil pressing plate to move up and down to compact the soil samples in the soil collection box. Through the cooperation of the lifting connecting frame and the second electric cylinder, the soil pressing plate can adjust its position in the soil collection box according to actual needs, and can adapt to the compaction requirements of different amounts of soil samples, thereby improving the versatility and adaptability of the equipment.

[0034] The lifting component 13 has a second drive motor 1301, and an active turntable 1302 is installed at the output end of the second drive motor 1301. The surface of the active turntable 1302 is connected to the driven turntable 1303 through a belt drive. A threaded rod 1304 is rotatably installed at the bottom of the driven turntable 1303. The surface of the threaded rod 1304 is threadedly connected to a lifting thread block 1305. A positioning connecting seat 1306 is fixedly installed on the right side of the lifting thread block 1305. The right side of the positioning connecting seat 1306 is connected to the surface of the soil collection cover 9.

[0035] Example 2:

[0036] Based on the first embodiment, the present invention is as follows Figure 6As shown, the positioning assembly 10 is disclosed to include a fixing seat 1001, and a tightening spring 1002 is installed on the upper and lower sides of the inner cavity of the fixing seat 1001, and a positioning card seat 1003 is fixedly installed on the inner end of the tightening spring 1002. The interior of the positioning card seat 1003 is provided with a mounting groove 1004, and the interior of the mounting groove 1004 is clamped and installed with a mounting block 1005. A soil collection box 1006 is fixedly installed on the right side of the mounting block 1005, and the collecting part of the soil collection box 1006 is sealed and fitted with the right surface of the soil collection cover 9; a compacting assembly 11 is installed inside the soil collection box 1006, and the compacting assembly 11 includes a soil pressing plate 1101, and a lifting connecting frame 1102 is fixedly installed on the upper end of the soil pressing plate 1101, and the upper end of the lifting connecting frame 1102 extends through to the top of the soil collection box 1006 and is installed with a second electric cylinder 1104.

[0037] Use Figure 1 The technical solution shown in the figure applies pressure against the spring 1002, so that the positioning card holder 1003 is tightly clamped to the installation card block 1005, thereby ensuring that the soil collection box 1006 is sealed and fitted with the right surface of the soil collection cover 9, effectively preventing the soil sample from leaking during the transmission process, ensuring the integrity and accuracy of the sample, and providing a reliable sample source for subsequent detection and analysis. The clamping structure of the mounting groove 1004 inside the positioning card holder 1003 and the installation card block 1005 makes the installation and removal process of the soil collection box 1006 relatively simple. When the soil collection box 1006 needs to be cleaned or replaced, the operation can be performed quickly, which improves the convenience of use and maintenance efficiency of the equipment; the second electric cylinder 1104 can drive the soil pressing plate 1101 to move up and down to compact the soil samples in the soil collection box 1006. Through the cooperation of the lifting connecting frame 1102 and the second electric cylinder 1104, the soil pressing plate 1101 can adjust its position in the soil collection box 1006 according to actual needs, and can adapt to the compaction requirements of different amounts of soil samples, thereby improving the versatility and adaptability of the equipment.

[0038] Secondly, in the technical solution, the second electric cylinder 1104 is located on the right side of the soil collection box 1006, and a support frame 1103 is fixedly installed on the bottom of the second electric cylinder 1104, and the left end of the support frame 1103 is connected to the right side of the soil collection box 1006; the lower end of the threaded rod 1304 is installed with a bottom support plate 14 through an embedded bearing, and the rear end of the bottom support plate 14 is connected to the side of the positioning vertical plate 2; the bottom of the second drive motor 1301 is fixedly installed with a motor supporting plate 15, and the motor supporting plate 15 is made of high-strength material, and the other end of the motor supporting plate 15 is welded to the back of the positioning vertical plate 2.

[0039] It uses Figure 1The technical solution shown in the figure sets the second electric cylinder 1104 on the right side of the soil collection box 1006, avoiding spatial interference with other components on the front or above the soil collection box 1006, making the overall structure of the equipment more compact, and realizing the reasonable layout of various components in a limited space. The left end of the support frame 1103 is connected to the right side of the soil collection box 1006. This structure provides stable support for the second electric cylinder 1104, ensuring that the second electric cylinder 1104 will not affect the compaction effect due to shaking or deviation when driving the soil pressing plate 1101 to perform compaction operation, thereby improving the stability and reliability of the compaction assembly 11. The bottom of the second drive motor 1301 is fixedly mounted on the motor bearing plate 15. The motor bearing plate 15 is made of high-strength material and can withstand the weight of the second drive motor 1301 and the vibration generated during operation. This structure ensures the stability of the second drive motor 1301 during operation, avoids the rotation accuracy of the active turntable 1302 affected by motor shaking, and thus ensures the normal operation of the lifting assembly 13.

[0040] Example 3:

[0041] The present invention Figure 1-Figure 7 As shown, a limiting slide is fixedly installed on the outside of the lifting threaded block 1305, and a sliding limiting vertical rod is embedded in the rear end of the limiting slide, and the right side of the limiting vertical rod is connected to the side of the positioning vertical plate 2; a through groove is opened inside the lower end of the positioning vertical plate 2, and one end of the belt connected between the active turntable 1302 and the driven turntable 1303 is located inside the through groove; the upper end of the soil pressing plate 1101 is set in a conical shape, and a leakage trough is opened inside the left side of the soil pressing plate 1101 and near the discharge trough 12.

[0042] By adopting the above technical solution, the cooperation between the limiting slide and the limiting vertical rod provides precise guidance for the threaded block. When the threaded rod 1304 rotates to drive the threaded block up and down, the limiting vertical rod limits the threaded block to move linearly along its direction, preventing the threaded block from offsetting or rotating during movement, ensuring that the soil collection cover 9 can be smoothly raised and lowered along the predetermined vertical direction, improving the accuracy of the sampling position, and the leakage trough near the discharge trough 12 can allow excess soil to be discharged through the trough. When there are too many soil samples or the soil is squeezed to the periphery of the soil pressing plate 1101 during the compaction process, the leakage trough can play a dredging role, avoiding soil accumulation between the soil pressing plate 1101 and the soil collection box 1006, preventing the discharge trough 12 from being blocked, and ensuring the normal collection of soil samples and the smooth progress of the compaction process.

[0043] A method for using an automated sampling device for environmental engineering project management, the specific method of use is as follows:

[0044] The first step is to start the first electric cylinder 4 and use its output end to push the driving seat 5 to move downward. Since the driving seat 5 cooperates with the slide rail 3, under the action of the first electric cylinder 4, the driving seat 5 can move downward along the slide rail 3 and simultaneously drive the first drive motor 7 and the drill rod 8 at the bottom to adjust the overall height;

[0045] Step 2: Then start the second drive motor 1301, and its output end drives the active turntable 1302 to rotate. The active turntable 1302 rotates the driven turntable 1303 through the belt drive. The threaded rod 1304 rotatably installed at the bottom of the driven turntable 1303 rotates clockwise, thereby driving the lifting threaded block 1305 on the surface and the positioning connection seat 1306 connected thereto and the soil collection cover 9 downward until the bottom of the soil collection cover 9 is completely stuck on the soil surface.

[0046] Step 3: When sampling and collecting soil, the first drive motor 7 drives the drill rod 8 to rotate at high speed, and the first electric cylinder 4 continues to work to drive the top plate 6 and the connected drill rod 8 downward through the drive base 5 to achieve soil drilling and collection. Since a conveying auger is installed on the surface of the drill rod 8, the drilled soil can be transported upward and discharged into the soil collection box 1006 through the discharge chute 12 for collection;

[0047] Step 4. After the soil sample is collected in the soil collection box 1006, the second electric cylinder 1104 is started. The second electric cylinder 1104 drives the soil pressing plate 1101 to move downward through the lifting connecting frame 1102. The upper end of the soil pressing plate 1101 is conical. This shape will not cause soil to remain on the top. The soil sample in the soil collection box 1006 can be compacted by the soil pressing plate 1101. Since the soil collection cover 9 and the drill rod 8 adopt a separate design, after the soil sampling is completed, the drill rod 8 is reset, and the second drive motor 1301 can be used to adjust the position of the soil collection cover 9 and move it out from the outside of the drill rod 8, which is convenient for cleaning the inner wall and preventing residue.
