Description

Technical Field

[0001] This invention relates to the field of geological testing equipment technology, and in particular to an automatic land assessment measuring device for construction engineering. Background Technology

[0002] Natural resources refer to substances in nature that humans can directly obtain for production and daily life. Land is a particularly important type of natural resource. In natural resource engineering, land assessment is often required. Land assessment is the process by which appraisers, based on the principles, theories, and methods of land valuation, and after fully understanding land market transaction data, consider the economic and natural attributes of the land, its quality and grade, and its general profitability in real economic activities. They also take into full account the impact of socio-economic development, land use patterns, expected land revenue, and land use policies on land revenue.

[0003] With the rapid development of the construction industry in China in recent years, in order to ensure the high-quality and efficient completion of projects, it is necessary to conduct environmental measurements on the construction site in the early stage. These environmental measurements mostly include measuring environmental factors such as temperature, noise, wind speed, soil quality, and slope.

[0004] Currently, soil testing involves manual analysis of sampled soil using appropriate equipment. Soil sampling is conducted using existing soil sampling drills, reaching depths of up to 30 meters. The sampling pipes are transparent plastic tubes, typically about one meter long. After sampling, each tube is removed, and the soil inside is extracted for testing. This presents several problems: First, construction sites are often large, requiring numerous soil samples. Manually analyzing these samples is time-consuming and labor-intensive. Second, construction sites often contain numerous... Large gravel will mix with the soil after sampling, affecting the test results. Third, removing soil from the sampling pipe requires striking the pipe to create voids, which can damage the pipe over time. Fourth, large amounts of soil will pollute the site during testing, making cleanup difficult. Fifth, large amounts of soil are difficult to collect and store for subsequent landfill operations. Sixth, the soil composition varies, and repeated testing of the site and equipment makes it difficult to ensure accuracy. Summary of the Invention

[0016] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0017] Firstly, this invention, through the coordinated operation of a weighing device, a display screen, sample pipes, a soil testing instrument, a base, a soil collection box, a pushing device, a drive separation device, a transmission device, a slide rail device, a sample placement device, a compaction device, a moving device, a flipping device, and a feeding device, can automatically detect soil temperature, soil moisture, soil salinity, soil pH value, and density. The test results can be viewed in detail on the display screen, and subsequent numerical comparisons are convenient after testing several liquid sampling pipes.

[0018] Secondly, the present invention can push the soil inside the sample tube out through the pushing device, so as not to damage the sample tube. At the same time, it can drive the sample placement device to move in position, so that the sample placement device can store the soil pushed out from the sample tube, thereby facilitating subsequent soil testing operations.

[0019] Thirdly, the present invention can also drive the sample placement device and the flipping device to achieve a flipping effect through the pushing device, so that the soil inside the sample placement device is poured into the soil collection box for storage. This facilitates the collection and storage of a large amount of soil after testing, which is convenient for subsequent soil landfill operations and avoids the difficulty of cleaning the testing site due to pollution. At the same time, it can also separate the excess soil from the soil inside the ring cutter cylinder, which is convenient for subsequent soil density testing and improves the accuracy of density testing.

[0020] Fourth, this device can sweep larger gravel and sticky soil into the soil collection box for storage by driving the separation device, thereby separating the soil and ensuring the accuracy of subsequent soil testing. This avoids the mixing of larger gravel and sticky soil into the soil, which would affect the accuracy of the test.

[0021] Fifth, this device can drive the compaction device to move through the separation device, thereby compacting the soil inside the ring cutter cylinder, which facilitates subsequent soil density testing. The soil on the outer wall of the ring cutter cylinder will be intercepted by the moving trough and fall into the placement seat. The soil density can be accurately detected by weighing the ring cutter cylinder with a weighing device, thus improving the accuracy of the test.

[0022] Sixth, the hollow design at the lower end of the sliding track allows excess soil to fall into the soil collection box during movement or other conditions, thus not affecting the normal operation of the equipment or the test results.

[0023] Seventh, this device uses a drive motor to rotate the separating brush to sweep and separate the soil. At the same time, it also drives the screw to rotate and compact the soil inside the ring cutter cylinder. When the separating brush rotates to separate the soil, it rotates several times until the compaction column on the screw is close to the same height as the sliding track. Then the drive motor can rotate in the opposite direction, so it will not affect the normal operation of either device. Attached Figure Description

[0042] Reference Figures 1-13As shown, this embodiment of the invention provides an automatic measuring device for land assessment in construction engineering, including a weighing device 1, a display screen 11, a sample pipe 12, and a soil tester 13. It is characterized by further including a base 14, a soil collection box 15, a pushing device 2, a drive-separation device 3, a transmission device 6, a slide rail device 4, a sample placement device 5, a compaction device 7, a moving device 8, a flipping device 9, and a feeding device 10.

The transmission device 6 is disposed on the drive-separation device 3. The slide rail device 4 is disposed on the inner side wall of the base 14 and located at the lower end of the drive-separation device 3. The sample placement device 5 is slidably disposed on the slide rail device 4 and connected to the pushing device 2. The compaction device 7 is disposed on the top inside the base 14 and connected to the transmission device 6. The flipping device 9 is disposed on the slide rail device 4. The moving device 8 is disposed on the base 14. On the inner wall of the base 14, the weighing device 1 is mounted on the slide rail device 4 and located below the moving device 8. The display screen 11 is mounted on the outer wall of the base 14. The soil detector 13 is mounted on the slide rail device 4. The base 14 is provided with a placement groove 141, a pushing groove 142, a through groove 143, and a dropping groove 144. The sample pipe 12 is located in the placement groove 141 on the base 14. The feeding device 10 is located below the placement groove 141 and connected to the moving device 8. The base 14 is also provided with a limiting block 145, which is located at the connection between the placement groove 141 and the dropping groove 144. The soil collection box 15 is located inside the base 14 and below the slide rail device 4. This device can automatically detect soil temperature, soil moisture, soil salinity, soil pH value, and density. It can also separate and collect soil from waste soil. After the soil test is completed, the soil can be collected and stored for subsequent landfill use.

[0043] Preferably, the pushing device 2 includes a pushing frame 21, a pushing hydraulic cylinder 22, a pushing block 23, a first pushing rod 24, a second pushing rod 26, and a pushing plate 27. The pushing frame 21 is disposed on the upper end of the base 14, the pushing hydraulic cylinder 22 is disposed on the pushing frame 21, one end of the pushing block 23 is connected to the output end of the pushing hydraulic cylinder 22, the lower end of the pushing block 23 passes through the through groove 143, and the upper end of the pushing block 23 is in sliding fit with the pushing groove 142. The first pushing rod 24 is disposed at the corner of the pushing block 23, the second pushing rod 26 is disposed at the lower end of the pushing block 23, the pushing block 23 is arranged in a figure-7 shape, the pushing plate 27 is disposed at the end of the second pushing rod 26, and the first pushing rod 24 is provided with a pushing piston head 25. The diameters of the pushing piston head 25 and the first pushing rod 24 are both smaller than the inner diameter of the sample pipe 12 and both are smaller than two millimeters. When testing soil samples, the required sample tube 12 is first placed in the placement groove 141, and the end of the sample tube 12 is placed against the limiting block 145. At the same time, the feeding device 10 supports the sample tube 12. Then, the operation of the hydraulic cylinder 22 drives the pushing block 23 on the output end of the hydraulic cylinder 22 to move towards the sample tube 12. The pushing block 23 is in a sliding engagement with the pushing groove 142, thereby driving the first pushing rod 24 and the pushing piston head 25 to move towards the sample tube 12. When the pushing piston head 25 moves into the sample tube 12, the soil inside the sample tube 12 is pushed by the pushing piston head 25, and all the soil inside the sample tube 12 is pushed out and falls into the drop groove 144, and then into the drive separation device 3, which facilitates the subsequent soil testing and separation.

[0044] Preferably, the drive separation device 3 includes a drive base 31, a drive motor 32, a drive shaft 33, a drive separation chamber 34, a filter screen 36, and a separation brush 37. The drive base 31 is disposed on the upper end of the base 14, the drive motor 32 is disposed on the drive base 31 with its output end facing downwards, the drive shaft 33 is disposed on the output end of the drive motor 32, the drive separation chamber 34 is disposed at the top inside the base 14, and the drive separation chamber 34 is connected to the drop groove 144. The separation brush 37 is sleeved on the drive shaft 33 and located inside the drive separation chamber 34. The filter screen 36 is disposed inside the drive separation chamber 34 and divides the drive separation chamber 34 into two parts. The filter screen 36 has an opening, and the drive separation chamber 34 has a soil waste outlet 35. The lower end of the separation brush 37 is in contact with the upper end of the filter screen 36. The lower end of chamber 34 is tapered. When the soil inside sample pipe 12 is pushed into the drive separation chamber 34, the soil will be on filter screen 36. Drive motor 32 drives drive shaft 33 at output end of drive motor 32 to rotate. Drive shaft 33 rotates and drives separation brush 37 to rotate away from the direction of push hydraulic cylinder 22. After separation brush 37 rotates several times, it will spread the soil on filter screen 36 evenly. At this time, most of the soil will fall into the lower chamber of drive separation chamber 34 through the holes of filter screen 36 and flow out through drive separation chamber 34. Some larger soil particles and gravel will be swept into the opening of filter screen 36 by the rotation of separation brush 37 and fall into soil collection box 15 through soil waste port 35 for storage, which facilitates subsequent soil testing. This realizes the movement of soil to the required position and the collection and processing of excess soil and gravel.

[0045] Preferably, the slide rail device 4 includes a support panel 41 and a sliding rail 42. The support panel 41 is disposed on the inner side wall of the base 14, and the sliding rail 42 is disposed on the support panel 41. The sliding rail 42 is provided with an inflow groove 421 and a detection groove 422, and two sliding grooves 423 are also provided on the sliding rail 42. The lower end of the sliding rail 42 is hollow. The inflow groove 421 is matched with the opening at the lower end of the drive separation chamber 34. The soil detector 13 is located on the inner side wall of the base 14 and its plug passes through the detection groove 422 and is fixedly connected to the detection groove 422. The soil detector 13 is electrically connected to the display screen 11, and the weighing device 1 is electrically connected to the display screen 11. The hollow lower end of the sliding rail 42 allows excess soil to fall into the soil collection box 15 during soil movement or other conditions.

[0046] Preferably, the sample placement device 5 includes a placement seat 51, a ring cutter cylinder 52, and placement shafts 53. The placement seat 51 is mounted on a sliding rail 42 and is slidably fitted left and right. The ring cutter cylinder 52 is located inside the placement seat 51 and is slidably fitted. There are two placement shafts 53, which are symmetrically arranged on both sides of the placement seat 51 and pass through corresponding sliding grooves 423. The placement seat 51 has grooves 511 identical to those in the detection groove 422. The two sides of the end of the push plate 27 are connected to the corresponding placement shafts 53 and are rotatably connected. When the hydraulic pressure is pushed... As cylinder 22 operates, it drives the piston head 25 on the first push rod 24 to push the soil out of the sample pipe 12. Simultaneously, the push block 23 drives the second push rod 26 to move. The movement of the second push rod 26 drives the push plate 27 to move towards the soil detector 13, thereby causing the sample placement device 5 to move on the sliding track 42. After all the soil inside the sample pipe 12 has been pushed out, the piston head 25 is now positioned next to the limit block 145, while the sample placement device 5 is located directly below the drive separation chamber 34 and on the sliding track 42, in the inflow groove 421. Below, the groove 511 on the placement seat 51 overlaps with the detection groove 422 on the sliding rail 42, so that the plug of the soil detector 13 passes through the groove 511 and is located inside the placement seat 51. At this time, the hydraulic cylinder 22 is stopped, and the separation brush 37 rotates several times through the drive motor 32, which then spreads the soil on the filter screen 36 evenly. The soil then falls into the placement seat 51 through the inflow groove 421 from the lower end of the drive separation chamber 34 for storage. The ring cutter cylinder 52 is now covered by soil, and the plug of the soil detector 13 is also covered by soil. During the covering process, the soil tester 13 is activated. The soil tester 13 tests the soil inside the placement base 51 and transmits the test data to the backend. The test data is displayed on the screen 11, making it convenient for personnel to view the test data and realize the soil testing operation. The soil tester 13 is a four-in-one soil tester in the prior art. The soil tester 13 is equipped with a soil moisture sensor, a soil temperature sensor, a soil salinity sensor and a soil pH sensor, so that it can detect soil temperature, soil moisture, soil salinity and soil pH value.

[0047] Preferably, the transmission device 6 includes a main gear 61, a driven gear 62, a transmission shaft 63, a driving wheel 64, a driven wheel 65, a transmission belt 66, a rotating shaft 67, and a transmission housing 68. The base 14 is provided with a storage groove 146. The main gear 61 is mounted on the drive shaft 33. The transmission shaft 63 is mounted in the storage groove 146 and is rotatably connected. The upper end of the transmission shaft 63 passes through the storage groove 146. The driven gear 62 is sleeved on the upper end of the transmission shaft 63. The main gear 61 meshes with the driven gear 62. The driving wheel 64 is mounted on the transmission shaft 63 and is located above the driven gear 62. The rotating shaft 67 is mounted on the base 14 and is rotatably connected. The driven wheel 65 is mounted on the rotating shaft 67. The transmission belt 66 is sleeved on the driving wheel 64 and the driven wheel 65. The transmission housing 68 covers the driving wheel 64 and the driven wheel 65.

[0048] Preferably, the compaction device 7 includes a compaction frame 71, a screw 72, a compaction rod 73, and a compaction column 74. The compaction frame 71 is located at the top inside the base 14 and beside the drive separation chamber 34. The upper end of the screw 72 is connected to the rotating shaft 67, and the lower end is connected to the compaction frame 71 in a rotatable connection. The compaction rod 73 is sleeved on the screw 72 and is threadedly connected. One end of the compaction rod 73 is connected to the compaction frame 71 and is in a sliding fit. The compaction column 74 is located at the lower end of the compaction rod 73. The diameter of the compaction column 74 is smaller than the inner diameter of the ring cutter cylinder 52 and is relatively close to it. The compaction column 74 and the axis of the ring cutter cylinder 52 are on the same straight line. When the soil tester 13 is placed on the base... After the soil temperature, humidity, salinity, and pH value of the soil inside 51 are tested, the hydraulic cylinder 22 is driven to move the push block 23 away from the sample pipe 12. At this time, the push block 23 will drive the second push rod 26 away from the soil analyzer 13, thereby causing the push plate 27 to drive the sample placement device 5 to disengage from the plug of the soil analyzer 13 and slide on the sliding track 42. During the movement of the sample placement device 5, the soil is affected by the force, and some soil will fall into the soil collection box 15 through the hollow position at the lower end of the sliding track 42 for storage. When the hydraulic cylinder 22 drives the axis of the ring cutter cylinder 52 to align with the axis of the compaction column 74, the hydraulic cylinder 22 is then activated. When hydraulic cylinder 22 stops operating, a controller on cylinder 22 precisely controls the movement of the equipment to the desired position. Then, the drive motor 32 rotates, causing the drive shaft 33 at its output to rotate. The rotation of drive shaft 33 drives the main gear 61, which in turn drives the driven gear 62. Meanwhile, the transmission shaft 63, located within storage slot 146, rotates in conjunction with the drive shaft 63. The rotation of drive shaft 63 drives the drive wheel 64, which, through a transmission belt 66, drives the driven wheel 65. The driven wheel 65 then rotates the rotating shaft 67 within transmission housing 68. The rotation of drive shaft 63 drives the screw 72 to rotate on the compaction frame 71, thus compacting the equipment. Rod 73 moves downwards on screw 72, while one end of compaction rod 73 is in a sliding engagement limit state on compaction frame 71, thereby driving compaction column 74 to move towards ring cutter cylinder 52, squeezing the soil inside placement seat 51 into ring cutter cylinder 52. Through the repeated up and down movement of compaction column 74, the soil inside ring cutter cylinder 52 is compacted. Then, drive motor 32 drives compaction column 74 back to its original position, facilitating the next soil operation. This device, through drive motor 32, can drive separation brush 37 to rotate to sweep and separate the soil, and at the same time drive screw 72 to rotate, compacting the soil inside ring cutter cylinder 52. When separation brush 37 rotates to separate the soil...After the separating brush 37 rotates several times until the compaction column 74 on the screw 72 is nearly at the same height as the sliding rail 42, the drive motor 32 can rotate in the opposite direction. Therefore, this will not affect the normal operation of either component.

[0049] Preferably, the moving device 8 includes a moving base 81, a moving hydraulic cylinder 82, a moving rod 83, a moving column 84, a left moving block 85, and a right moving block 86. The sliding track 42 is also provided with two moving slots 424. The moving base 81 is disposed on the inner wall of the base 14. The moving hydraulic cylinder 82 is disposed on the moving base 81. The moving rod 83 is disposed on the inner wall of the base 14 and located to one side of the moving hydraulic cylinder 82. The moving column 84 is sleeved on the moving rod 83 in a sliding fit. One end of the moving column 84 is connected to the output end of the moving hydraulic cylinder 82. The moving column 84 is U-shaped. The left moving block 85 and the right moving block 86 are symmetrically arranged on the inner sides of both ends of the moving column 84 and correspond to the two moving slots 424 on the sliding track 42. The size of the moving slot 424 on the side of the moving hydraulic cylinder 82 is adapted to the ring cutter cylinder 52. The weighing device 1 is located next to the moving slot 424 on the side of the moving hydraulic cylinder 82 and the height of the weighing device 1 is the same as the height of the bottom of the ring cutter cylinder 52. The lower ends of the left moving block 85 and the right moving block 86 do not contact the upper end of the weighing device 1. The one located on the side of the weighing device 1 is the right moving block 86, and the other is the left moving block 85.

[0050] Preferably, the flipping device 9 includes a flipping gear 91 and a flipping rack 92. A soil feeding trough 425 is also provided on the sliding track 42. The flipping gear 91 is sleeved on the placement shaft 53 located on one side of the left moving block 85. The flipping rack 92 is located on the outer side of the sliding track 42 and opposite to the weighing device 1. A limiting rod 426 is provided on the moving groove 424 near the moving hydraulic cylinder 82. When the soil inside the ring cutter cylinder 52 on the placement seat 51 is compacted, the compaction device 7 returns to its original position by driving the separation device 3. This drives the hydraulic cylinder 22 to move the pushing block 23 away from the sample pipe 12, thereby driving the pushing plate 27 on the second pushing rod 26 to move away from the soil detector 13. When the flipping gear 91 on the placement shaft 53 moves with the pushing plate 27, the flipping gear 91 and the placement rack 92... When the strips are engaged, the end of the placement seat 51 is located at the soil discharge trough 425. Then, through the continuous movement of the push plate 27, the flip gear 91 moves on the flip rack 92, thereby driving the flip gear 91 to rotate. The rotation of the flip gear 91 drives the corresponding placement shaft 53 to rotate, and the rotation of the placement shaft 53 drives the placement seat 51 to rotate. Meanwhile, the other end of the placement shaft 53 is in a cooperating rotation state. When the placement seat 51 rotates 180 degrees, the soil inside the placement seat 51 will fall into the soil collection box 15 for storage due to gravity. The soil inside the ring cutter cylinder 52 will not fall out unless it is impacted. Then, by moving the push plate 27 towards the soil detector 13, the placement seat 51 is moved back to its original position, thereby removing excess soil to facilitate the subsequent soil density detection operation inside the ring cutter cylinder 52.

[0051] The movement of the push plate 27 drives the sample placement device 5 to move so that the ring cutter cylinder 52 is in a corresponding state with the two moving slots 424, and also with the left moving block 85 and the right moving block 86. At this time, the push block 23 also drives the push piston head 25 on the first push rod 24 to disengage from the inside of the sample pipe 12. The push piston head 25 is now located outside the sample pipe 12. Then, the movement of the moving hydraulic cylinder 82 drives the moving column 84 on the output end of the moving hydraulic cylinder 82 to move towards the weighing device 1 on the moving rod 83. At this time, the left moving block 85 passes through the corresponding moving slot 424 and pushes the ring cutter cylinder 52 on the placement seat 51 towards the weighing device 1. The left moving block 85 pushes the ring cutter cylinder 52 out of the placement seat 51 and limits it with the limiting rod 426 so that the ring cutter cylinder 52 can return to the weighing device 1 later. The original position is now exactly on the weighing device 1. During the pushing process of the ring cutter cylinder 52, the size of the moving groove 424 is adapted to the ring cutter cylinder 52. The soil on the outer wall of the ring cutter cylinder 52 is intercepted by the moving groove 424 and falls into the placement seat 51. Thus, the weighing operation of the ring cutter cylinder 52 by the weighing device 1 can accurately detect the soil density. The soil density detection method is as follows: the mass of the soil in the ring cutter cylinder 52 divided by the volume of the ring cutter cylinder 52 equals the wet density of the soil. The wet density divided by (1 + water content) equals the dry density of the soil. The dry density divided by the standard dry density of the soil equals the compaction degree. After the weighing device 1 has completed the weighing of the required mass of the ring cutter cylinder 52, the detection data will be transmitted to the back-end. The back-end will verify the data and display the detection data on the display screen 11, so that personnel can easily view the detection data and realize the soil detection operation.

[0052] After the ring cutter cylinder 52 has been weighed, the moving hydraulic cylinder 82 drives the right moving block 86 to push the ring cutter cylinder 52 back to its original position. The limit rod 426 can limit the ring cutter cylinder 52 to prevent it from deviating during the movement. During the process of returning the ring cutter cylinder 52 to its original position, the ring cutter cylinder 52 will hit the moving groove 424 on the side away from the moving hydraulic cylinder 82. At this time, the moving groove 424 plays a role in limiting and blocking. The impact of the ring cutter cylinder 52 will loosen the soil inside the ring cutter cylinder 52. Then, according to the above description, the placement seat 51 is rotated 180 degrees to let the soil inside the ring cutter cylinder 52 fall into the soil collection box 15 for storage, so as to facilitate the subsequent soil re-testing operation.

[0053] Preferably, the feeding device 10 includes a feeding rod 101 and a feeding plate 102. The feeding rod 101 is mounted on the moving column 84, and the feeding plate 102 is mounted on the feeding plate 102 and located below the placement groove 141. The feeding plate 102 has an inclined surface. The movement of the push plate 27 drives the sample placement device 5 to move so that the ring cutter cylinder 52 is in a corresponding state with the two moving grooves 424, and also in a corresponding state with the left moving block 85 and the right moving block 86. At this time, the push block 23 also drives the push piston head 25 on the first push rod 24 to disengage from the inside of the sample tube 12. The push piston head 25 is now located outside the sample tube 12. During the process of the moving hydraulic cylinder 82 pushing the ring cutter cylinder 52 out of the placement seat 51 for soil testing, the moving column 84 also drives the feeding rod 101 to move towards the weighing device 1. The movement of the feeding rod 101 will drive the feeding plate 102 to move, thereby causing the feeding plate 102 to detach from the placement groove 141. At this time, the sample pipe 12 is not affected by the supporting force of the feeding plate 102 and will fall out of the device through the inclined surface of the feeding plate 102, thus realizing the feeding operation of the sample pipe 12. After the moving hydraulic cylinder 82 drives the feeding plate 102 back to its original position, the sample pipe 12 to be tested can be placed in the placement groove 141 for testing.
