Description

Technical Field

[0001] The invention belongs to the technical field of soil organic carbon detection, and in particular is a soil sampling device for soil organic carbon detection. Background Art

[0002] The soil sampling device for soil organic carbon detection is a tool or equipment specially designed for collecting soil samples for organic carbon content detection. The main function of this device is to collect representative and accurate soil samples for subsequent precise detection of organic carbon content. Through the collected soil samples, the organic carbon content in the soil can be analyzed, and then the quality and fertility of the soil can be evaluated, providing important data support for agricultural management, environmental monitoring and soil science research.

[0003] When the traditional soil sampling device for soil organic carbon detection is working, the slave motor is started, and the rotating disk and the round block are driven to rotate through the meshing transmission of the bevel gear. The rotation of the round block is driven by the slide slot and the vertical rod to make the inclined plate reciprocate, thereby pushing the soil into the storage barrel. At the same time, the spiral drill bit also drills into the soil with the rotation of the rotating disk to further collect soil samples. The electric push rod can be extended and retracted to drive the connecting rod to swing, and then the digging component and the sampling component can be swung and rotated through the meshing transmission of the half gear, so that the depth and angle of digging and sampling can be adjusted to meet the requirements of different soil types and depths.

[0004] However, when taking soil samples, the device is directly placed in the sampling area and then a drill tube is used for sampling. This design does not fully consider the linkage between the various mechanisms, and the design concept often focuses more on the realization of a single function, resulting in the inability to ensure the portable movement and stable fixation of the device. Summary of the invention

[0005] In order to solve the problem of functional separation and lack of linkage proposed in the above background technology, thereby making it difficult to ensure the portable movement and stable fixation of the device, the present invention provides a soil sampling device for soil organic carbon detection.

[0007] The pedal mechanism comprises a slide plate slidably connected to the protective shell, a spring fixedly connected to the bottom surface of the slide plate, and a pedal fixedly connected to the bottom of the spring;

[0008] The linkage member comprises a connecting rod, one end of which is movably connected to a rotating rod, a rotating shaft is fixedly connected inside the rotating rod, and one end of the rotating rod is movably connected to a lifting rod.

[0012] Preferably, stabilizing plates are symmetrically arranged on both sides of the motor box, a buffer spring is fixedly connected to the top of the stabilizing plate, a buffer pressure rod for buffering is sleeved inside the buffer spring, an A plate is fixedly connected to the top surface of the buffer spring, and the A plate is connected to the inner wall of the protective shell.

[0013] Preferably, a sliding block is fixedly connected to the middle of the bottom surface of the skateboard, a sliding groove adapted to the sliding block is provided on the outer surface of the protective shell, the foot pedal is also slidably connected to the protective shell, and a U-shaped plate is fixedly connected to the top surface of the skateboard.

[0014] Preferably, the bottom end of the connecting rod is connected to the U-shaped plate, the rotating rod can be automatically retracted, both ends of the rotating shaft pass through the rotating rod and are rotatably connected to a bracket, and one side of the bracket is connected to one side of the guide rail.

[0015] Preferably, the lifting rod is located inside the guide rail, and the lifting rod is slidably connected to the guide rail.

[0016] Preferably, the moving mechanism comprises a base and universal wheels, and the universal wheels are fixedly connected to the bottom surface of the base.

[0017] Preferably, a connecting column is fixedly connected to the bottom surface of the lifting rod, and the bottom surface of the connecting column is connected to the top surface of the base.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention cooperates with structures such as a foot pedal mechanism and a linkage member so that the linkage member can link the foot pedal mechanism and the moving mechanism, thereby ensuring the portable movement and stable fixation of the device. The operator steps on the foot pedal with his foot, and the foot pedal slides on the protective shell through a slide plate connected by a spring, and the sliding block in the middle of the bottom surface of the slide plate slides in the slide groove on the outer surface of the protective shell to ensure the stable movement of the slide plate, and the U-shaped plate fixedly connected to the top surface of the slide plate drives the connecting rod to move, and the connecting rod pushes the rotating rod to rotate around the rotating shaft. Since the two ends of the rotating shaft are connected to one side of the guide rail through a bracket, a lifting rod movably connected to one end of the rotating rod slides upward in the guide rail, and the connecting column on the bottom surface of the lifting rod drives the base and the universal wheel fixedly connected to the bottom surface to rise. Through the cooperation of components such as the foot pedal, the slide plate, the spring, the connecting rod, the rotating rod and the lifting rod, the operator can easily control the lifting and lowering of the universal wheel to achieve the fixation and movement of the device. This design makes the device more stable during operation and reduces the influence of shaking or displacement on the sampling result.

[0020] The design of the soil pushing mechanism plays a role in facilitating sample pushing. The hydraulic telescopic rod is started, and the hydraulic telescopic rod pushes the motor box fixedly connected to the bottom to move downward. The driving motor in the motor box drives the drill barrel to rotate, and the drill barrel drills into the soil to perform soil extraction operations. The stabilizing plates symmetrically arranged on both sides of the motor box, the buffer spring fixedly connected to the top, the internally sleeved buffer hydraulic rod, and the A plate fixedly connected to the top surface are connected to the inner wall of the protective shell, which play a stabilizing and buffering role in the soil extraction process. The soil pushing mechanism is started, and the two hydraulic rods connected to the fixed bars symmetrically distributed on both sides of the motor box push the extrusion plate downward inside the drill barrel. The soil sample in the drill barrel is pushed out by the extrusion plate for subsequent organic carbon detection. After the sampling and detection are completed, the pedal mechanism is operated in reverse to make the universal wheel drop to touch the ground, and the device is carried away from the sampling site by the portable handle. From the drilling barrel entering the soil to the sample pushing out, the whole sampling process is standardized, stable and reliable, which can maximize the integrity and representativeness of the soil sample. The soil pushing mechanism adopts a hydraulic rod to push the extrusion plate, which can easily push out the soil sample in the drill barrel. This method is simple to operate and has uniform force, which ensures that the sample is completely taken out of the drill barrel, which provides convenience for the subsequent organic carbon detection.

Through the cooperation of the foot pedal 53, the slide plate 51, the spring 52, the connecting rod 61, the rotating rod 62 and the lifting rod 64, the operator can easily control the lifting and lowering of the universal wheel to achieve the fixation and movement of the device. This design makes the device more stable during operation and reduces the impact of shaking or displacement on the sampling results.

[0035] The driving motor 31 is located in the motor box 21, and provides rotational power for the drill barrel 32, so that it can drill into the soil to collect soil samples. Driven by the driving motor 31, the drill barrel 32 rotates and drills into the soil to collect soil samples. The design of the soil pushing mechanism 4 plays a role in convenient sample pushing. The hydraulic telescopic rod 2 is started, and the hydraulic telescopic rod 2 pushes the motor box 21 fixedly connected to the bottom to move downward. The driving motor 31 in the motor box 21 drives the drill barrel 32 to rotate, and the drill barrel 32 drills into the soil to perform soil extraction operations. The stabilizing plates 8 symmetrically arranged on both sides of the motor box 21, the buffer springs 81 fixedly connected to the top, the internally sleeved buffer hydraulic rods 82, and the A plate fixedly connected to the top surface are connected to the inner wall of the protective shell 1.

The squeezing plate 41 pushes the soil sample in the drill barrel 32 to facilitate subsequent organic carbon detection. After the sampling and detection are completed, the pedal mechanism 5 is operated in reverse to make the universal wheel drop to contact the ground, and the device is carried away from the sampling site by the portable handle.

The stabilizing plate 8 is located on both sides of the motor box 21, and is connected to the buffer spring 81 and the buffer hydraulic rod 82, so as to provide stability for the soil taking mechanism 3. The buffer spring 81 plays a buffering role in the soil taking process to reduce vibration Regarding the impact on the soil-taking operation, the buffer hydraulic rod 82 and the buffer spring 81 provide a buffering and supporting effect together to improve the stability of the soil-taking operation. The slide plate 51 is slidably connected to the protective shell 1 and is connected to the foot pedal 53 through the spring 52.
