Description

Technical Field

[0001] This invention relates to the technical field of highway construction, specifically a soil testing and sampling device for highway engineering. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, landscaping and traffic monitoring facilities, as well as buildings, workshops, and other service facilities used for construction, maintenance, and monitoring. Soil sampling is a crucial aspect of highway engineering. To ensure the quality of highway projects, regular soil quality testing is necessary, and soil sampling often requires the use of soil testing samplers.

[0003] Traditional soil testing samplers typically use a soil drill to collect soil samples, which are then stored in a collector. However, soil conditions vary on different road sections, and the collector must be thoroughly cleaned before the next sampling can begin, leading to low efficiency on roads with poor soil conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a soil testing and sampling device for highway engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A soil testing and sampling device for highway engineering includes a base and a support frame fixedly installed on the base. A threaded pusher is installed on the support frame, and a sampling device is installed on one end of the threaded pusher. The threaded pusher is connected to the sampling device through a transmission component. Symmetrically arranged elastic extrusion members are installed on the support frame and connected to the sampling device; after the sampling work is completed, the elastic extrusion members deform to expel the soil in the sampling device. A sampling device is installed on the base and connected to the sampling device. The sampling device includes multiple sampling tubes arranged in a circular pattern. The soil that is squeezed in the sampling device can fall into the sampling tubes, and the position of the sampling tubes changes when the sampling device takes a second sample.

[0007] As a further embodiment of the present invention: the threaded pusher includes a first lead screw, which is rotatably mounted on the support frame. The first lead screw is driven to rotate by a motor fixedly mounted on the support frame. A threaded sleeve is threadedly connected to the first lead screw, and a connecting sleeve is fixedly mounted on the threaded sleeve. The sampling device is rotatably mounted on the end of the threaded sleeve away from the first lead screw.

[0008] As a further embodiment of the present invention, the sampling device includes a rotating component, which is rotatably mounted on the threaded sleeve. A sampler is fixedly disposed on the end of the rotating component away from the threaded sleeve. An extrusion block is disposed axially inside the sampler, and a circumferentially distributed clamping tooth is formed on the end of the sampler where sampling is performed.

[0009] As a further embodiment of the present invention: the transmission component includes a plug-in cylinder and a plug-in shaft. The plug-in cylinder is rotatably mounted on the support frame. The plug-in cylinder is rotatably connected to the first lead screw through a first gear set. The plug-in shaft is slidably disposed inside the plug-in cylinder. One end of the plug-in shaft away from the plug-in cylinder is rotatably connected to the rotating component through a second gear set. The connecting sleeve is rotatably connected along the axial direction of the plug-in shaft.

[0010] As a further embodiment of the present invention: the elastic extrusion member includes a telescopic cylinder and a telescopic rod, and through grooves are symmetrically formed on the support frame. The telescopic cylinder and the telescopic rod are slidably disposed in the through grooves, and the telescopic rod is slidably disposed in the telescopic cylinder. A connecting member is fixedly disposed on the end of the telescopic rod away from the telescopic cylinder. The connecting member is arranged in an L-shape. The end of the connecting member away from the telescopic rod passes through the sampler and is fixedly connected to the extrusion block. The connecting member can slide relative to the sampler. It also includes a spring, which is disposed in the through groove. One end of the spring is fixedly connected to the telescopic cylinder, and the other end is fixedly connected to the top of the inner side of the through groove.

[0011] As a further embodiment of the present invention: the sample collection device includes symmetrically arranged second lead screws, which are rotatably mounted on the base. A transmission shaft is rotatably mounted on the support frame. The transmission shaft is rotatably connected to the first lead screw via a bevel gear set. The transmission shaft is rotatably connected to two second lead screws respectively via belts. A threaded sleeve is threadedly connected to the second lead screw. A ratchet plate is fixedly connected to one of the threaded sleeves. A movable plate is fixedly mounted on the threaded sleeve. A turntable is rotatably mounted on the movable plate, and the rotation axis of the turntable passes through the movable plate. The sampler is mounted on the turntable. The threaded sleeve can be connected to the rotation axis of the turntable via a one-way transmission component.

[0012] As a further embodiment of the present invention: the one-way transmission component includes a receiving shaft, the receiving shaft is rotatably mounted on the base, a ratchet adapted to the ratchet plate is fixedly provided on the receiving shaft, and the receiving shaft is rotatably connected to the rotating shaft of the turntable through a second gear set.

[0013] As a further aspect of the present invention: a through hole is formed on the base, and the sampler can pass through the through hole to take a sample.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention controls the operation of the threaded pusher to push the sampling device to move. Under the action of the transmission component, the sampling device rotates while moving, so that it can be inserted into roads with different soil hardness to complete the soil sampling. After the soil is collected, during the reset process of the sampling device, the elastic extrusion component is compressed to generate stored elastic potential energy. At the same time, the sampling collection device is driven to work. When the sampling device is fully reset, the collection tube on the collection device is already directly below the sampling device, so that the soil in the sampling device can fall into the collection tube after being squeezed by the elastic extrusion component, thus completing the soil sampling and collection work. Moreover, it can continuously sample different soil types, and the soil samples taken from different sections of the road can be collected in different collection tubes, increasing the accuracy and efficiency of soil testing and sampling.

[0024] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0025] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0026] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0027] Please see Figures 1-8 In this embodiment of the invention, a soil testing and sampling device for highway engineering includes a base 1, a support frame 2, a sample collection tube 18, a threaded pusher, a sampling device, an elastic extrusion member, and a sample collection device.

[0028] Specifically, the following are included: Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 The base 1 and the support frame 2 fixedly installed on the base 1, the support frame 2 is equipped with a threaded pusher, and a sampling device is installed on one end of the threaded pusher. The threaded pusher is connected to the sampling device through a transmission component. Symmetrically arranged elastic extrusion members are installed on the support frame 2 and connected to the sampling device; after the sampling work of the sampling device is completed, the elastic extrusion members deform to expel the soil in the sampling device. A sampling device is installed on the base 1 and connected to the sampling device. The sampling device includes a plurality of sampling tubes 18 arranged in a circular pattern. The soil that is squeezed in the sampling device can fall into the sampling tubes 18, and the position of the sampling tubes 18 changes when the sampling device takes a second sample.

[0029] In detail, during soil sampling, considering the varying hardness of different soil types, a driving mechanism is typically used to control the sampling process. In this invention, the driving mechanism is mounted on a threaded pusher, which controls the operation of the threaded pusher to move the sampling device. Under the action of the transmission mechanism, the sampling device rotates while moving, allowing it to be inserted into roads with varying soil hardness to complete the soil sampling. After the soil is collected, during the resetting process of the sampling device, the elastic extrusion member is compressed to store elastic potential energy, while the collection device is driven to operate. When the sampling device is fully reset, the collection tube 18 on the collection device is directly below the sampling device, allowing the soil inside the sampling device to fall into the collection tube 18 after being compressed by the elastic extrusion member. This completes the soil sampling and collection process, and allows for continuous sampling of different soil types. Soil samples from different sections of the road can be collected in different collection tubes 18, increasing the accuracy and efficiency of soil testing and sampling.

[0030] The threaded pusher includes a first lead screw 4, which is rotatably mounted on the support frame 2. The first lead screw 4 is driven to rotate by a motor 3 fixedly mounted on the support frame 2. A threaded sleeve 5 is threadedly connected to the first lead screw 4, and a connecting sleeve 12 is fixedly mounted on the threaded sleeve 5. The sampling device is rotatably mounted on the end of the threaded sleeve 5 away from the first lead screw 4.

[0031] The sampling device includes a rotating component 6, which is rotatably mounted on the threaded sleeve 5. A sampler 7 is fixedly installed on the end of the rotating component 6 away from the threaded sleeve 5. An extrusion block 25 is arranged axially inside the sampler 7. A circumferentially distributed clamping tooth is formed on the end of the sampler 7 where sampling is performed.

[0032] To elaborate, the motor 3 starts working, and the motor 3 controls the first lead screw 4 to rotate for a certain period of time, then rotates in the opposite direction. After rotating the same number of times in both directions, it stops working. When sampling begins, the rotation of the first lead screw 4 drives the threaded sleeve 5 to move linearly along the axis of the first lead screw 4. As the threaded sleeve 5 moves, it drives the sampler 7 towards the ground. At the same time, under the action of the transmission component, the sampler 7 itself rotates, and its locking teeth can break open the road surface, thereby softening the soil and ensuring that the sampler 7 can collect soil samples. The soil is temporarily stored in the sampler 7. At this time, the first lead screw 4 reverses and drives the sampler 7 to reset. The sampler 7 does not rotate during the reset process to avoid the soil in the sampler 7 falling out. During the reset process, the sampler 7 exerts a squeezing force on the elastic extrusion member. After the sampler 7 is fully reset, the elastic extrusion member is in a compressed state. At this time, the force on the elastic extrusion member disappears and exerts a reverse elastic force on the extrusion block 25. The soil in the sampler 7 falls into the collection tube 18 under the push of the extrusion block 25, thus completing the soil sampling and collection work.

[0033] Please see Figure 5 and Figure 6 The transmission component includes a plug-in cylinder 8 and a plug-in shaft 9. The plug-in cylinder 8 is rotatably mounted on the support frame 2. The plug-in cylinder 8 is rotatably connected to the first lead screw 4 through a first gear set 10. The plug-in shaft 9 is slidably disposed inside the plug-in cylinder 8. One end of the plug-in shaft 9 away from the plug-in cylinder 8 is rotatably connected to the rotating component 6 through a ratchet gear set 11. The connecting sleeve 12 is rotatably connected along the axial direction of the plug-in shaft 9.

[0034] Preferably, at least one set of limiting grooves 801 is provided inside the plug-in cylinder 8, and a limiting slider 901 is formed on the plug-in shaft 9 to slide in cooperation with the limiting grooves 801. The limiting slider 901 is slidably disposed in the limiting grooves 801. With the cooperation of the limiting slider 901 and the limiting grooves 801, the plug-in shaft 9 can slide relative to the plug-in cylinder 8, and the plug-in shaft 9 can rotate synchronously when the plug-in cylinder 8 rotates.

[0035] It should be noted that the ratchet gear set 11 includes a ratchet and a gear, which are respectively installed on the rotating part 6 and the plug shaft 9, thereby enabling unidirectional transmission between the rotating part 6 and the plug shaft 9. During the reset process of the sampler 7, the plug shaft 9 cannot drive the rotating part 6 to rotate, thus preventing the soil sampled in the sampler 7 from falling out completely before it is collected.

[0036] The elastic extrusion component includes a telescopic cylinder 27 and a telescopic rod 28. The support frame 2 has symmetrical through slots. The telescopic cylinder 27 and the telescopic rod 28 are slidably disposed in the through slots. The telescopic rod 28 is slidably disposed in the telescopic cylinder 27. A connector 26 is fixedly disposed on the end of the telescopic rod 28 away from the telescopic cylinder 27. The connector 26 is L-shaped. The end of the connector 26 away from the telescopic rod 28 passes through the sampler 7 and is fixedly connected to the extrusion block 25. The connector 26 can slide relative to the sampler 7. It also includes a spring 29, which is disposed in the through groove. One end of the spring 29 is fixedly connected to the telescopic cylinder 27, and the other end is fixedly connected to the top of the inner side of the through groove.

[0037] Initially, the spring 29 is in its natural state. During the sampling process of the sampler 7, the spring 29 is in a stretched state from the beginning. When the telescopic rod 28 moves to the point where it can drive the telescopic cylinder 27 to move synchronously, the spring 29 is in a stretched state. Subsequently, when the sampler 7 is fully reset, the spring 29 is in a fully compressed state. At this time, the elastic potential energy stored in the spring 29 is at its maximum value. After the squeezing force is lost, the spring 29 deforms and generates elastic force on the movement of the squeezing block 25, so that the soil in the sampler 7 can fall into the collection tube 18, completing the soil sampling work.

[0038] Please see Figure 1 , Figure 3 , Figure 8 The sample collection device includes symmetrically arranged second lead screws 19, which are rotatably mounted on the base 1. A drive shaft 14 is rotatably mounted on the support frame 2. The drive shaft 14 is rotatably connected to the first lead screw 4 through a bevel gear set 13. The drive shaft 14 is rotatably connected to the two second lead screws 19 through belts 15. A threaded sleeve 20 is threadedly connected to the second lead screw 19. A ratchet plate 21 is fixedly connected to one of the threaded sleeves 20. A movable plate 16 is fixedly mounted on the threaded sleeve 20. A turntable 17 is rotatably mounted on the movable plate 16, and the rotating shaft of the turntable 17 passes through the movable plate 16. The sample collection tube 18 is provided on the turntable 17. The threaded sleeve 20 can be connected to the rotating shaft of the turntable 17 through a one-way transmission component.

[0039] The one-way transmission component includes a receiving shaft 22, which is rotatably mounted on the base 1. A ratchet 23 adapted to the ratchet plate 21 is fixedly provided on the receiving shaft 22. The receiving shaft 22 is rotatably connected to the rotating shaft of the turntable 17 through a second gear set 24.

[0040] Furthermore, when the first lead screw 4 rotates, it drives the transmission shaft 14 to rotate via the bevel gear set 13. When the transmission shaft 14 rotates, it drives the second lead screw 19 to rotate synchronously via the belt 15. When the second lead screw 19 rotates, it drives the threaded sleeve 20 to move linearly along the axial direction of the second lead screw 19. When the threaded sleeve 20 moves, it drives the movable plate 16 to move synchronously, making way for the movement of the sampler 7. This ensures that the sampler 7 does not interfere with the sample collection tube 18 when it moves. At the same time, when the ratchet plate 21 on the threaded sleeve 20 meshes with the ratchet 23, it drives... When the receiving shaft 22 rotates, it drives the turntable 17 to rotate through the second gear set 24. The second gear set 24 includes a full gear and a half gear. The full gear is installed on the rotating shaft of the turntable 17, and the half gear is installed on the receiving shaft 22. The angle of deflection of the turntable 17 is limited, so that when the sampling work is finished, the sampler 7 and the empty sample collection tube 18 are on the same axis, ensuring that the sampled soil can fall completely into the sample collection tube 18. This not only avoids the sampled soil from scattering everywhere, but also enables the sampling of different soil types.

[0041] A through hole is formed on the base 1, and the sampler 7 can pass through the through hole to take a sample.
