Description

Technical Field

[0001] The invention relates to the technical field of plant root tensile strength measurement, in particular to a device and a method for measuring the tensile mechanical properties of plant roots. Background Art

[0002] The device and method for measuring the tensile mechanical properties of plant roots are designed to accurately measure key mechanical parameters of plant roots, such as tensile strength, maximum tensile force, and elongation. These parameters are of great significance for evaluating the role of plant roots in soil consolidation and slope protection, and are key indicators for measuring the effectiveness of root protection.

[0003] The measuring device usually consists of two parts: a mechanical device and an electronic measuring system. The mechanical device includes a fixed frame, a root clamping mechanism and a transmission system, which are used to clamp and stretch root samples. The electronic measuring system includes sensors, a data acquisition system and a handheld device, which are used to record and analyze the tensile mechanical properties of the roots in real time. The operating process includes root sampling, cleaning, grading, clamping, stretching and data analysis. The device and the measuring method have the advantages of easy portability, accurate measurement and easy operation. They can quickly obtain the tensile mechanical properties of the roots on site and display their stress-strain relationship curves, meeting the needs of various application scenarios in the field and indoors.

[0019] The present invention also provides a method for measuring the tensile mechanical properties of plant roots, comprising the following steps:

[0020] S1. The grass roots pass through the connection groove on the special-shaped block, and the tension spring drives the sliding clamp through the round block to initially clamp the two ends of the grass roots, preparing for subsequent fixation;

[0021] S2. The grass roots pass through the circular ring block, and the internal short thread spring pushes the short cylinder, driving the arc-shaped clamping plate to fit the grass roots tightly. The elasticity of the short thread spring is used to apply pressure from the circumferential direction to achieve the initial stable fixation of the grass roots;

[0022] S3, start the asynchronous motor and the servo motor to drive the special-shaped arc block and the driving arc block to rotate, drive the moving clamp and the fixed clamp to move, the electric slider moves on the long slide rail, drives the square plate and other components to move, and at the same time, the long threaded spring on the short slide rail drives the moving clamp and the fixed clamp to move;

[0023] S4, when the moving clamp and the fixed clamp move, the spikes contact and penetrate the soft grass roots to firmly clamp them, and the hard grass roots push the spikes to trigger the sensor to judge the softness and hardness;

[0024] S5. When the grass root slides under the tension, it drives the ring block and transmits it to the clamping plate through the small ball. The clamping plate slides through the connecting slider, and the long spring rod pushes the rubber plate to further clamp the grass root. The rubber plate fits the shape of the grass root and applies uniform pressure. Multiple groups of long spring rods are used to ensure that the grass root is stably fixed in all directions.

[0025] S6. The electric slider drives the square plate to slide on the long slide rail, pushing the thrust measuring device to accurately measure the tensile force of the grass roots. The tensile mechanical properties of the grass roots can be obtained by recording and analyzing the data.

[0026] S7. At the same time, after the measurement, the connecting rod is clamped and supported by the sliding clamping block under the support of the threaded spring rod to prepare for the next measurement and avoid displacement or damage of the components.

[0027] Compared with the prior art, the present invention provides a device and method for measuring the tensile mechanical properties of plant roots, which has the following beneficial effects:

[0028] 1. In order to make the device more accurately measure the tensile force of the plant roots, a tension component is provided. The component cooperates with the electric slider to slide on the long slide rail to adjust the position. The asynchronous motor drives the special-shaped arc block to rotate to provide tension. The long thread spring and the fixed plate play a buffering and stabilizing role between the short slide rail and the short slider, and the guide rail and the short slide. The movable splint and the fixed splint can fix the plant roots, which is conducive to accurately measuring the tensile mechanical properties of the plant roots.

[0029] 2. In order to ensure that the root system of the device is stable and intact during the detection process, a clamping assembly is provided. The assembly cooperates with the connecting slider to slide in the connecting slot to adjust the clamping position. The long spring rod and the rubber plate provide elastic buffering during clamping. Multiple groups of structures are set with the center line of the support block as the mirror axis to ensure the balance of clamping. The clamping force can be adaptively adjusted according to the shape of the root system through the hinged hinge plate and the specially designed circular ring block, short threaded spring, short cylinder, and arc-shaped clamping plate. The rubber plate made of soft rubber material avoids damaging the root system, ensuring that the root system is stable and intact during the detection process.

[0030] 3. In order to enable the device to provide a stable supporting environment for accurately measuring the tensile mechanical properties of the root system, a supporting assembly is provided, which cooperates with the supporting bar to provide basic support for the whole. The threaded spring rod is retractable, and the height and strength of the support can be adjusted by changing its length. The slide of the supporting slide block enables the clamping plate to slide, thereby adjusting the position of the clamping block. Multiple groups of structures are set with the center line of the support block as the mirror axis to ensure the symmetry and stability of the support. This design can flexibly adjust the support position and strength according to the length, thickness and detection angle of the plant root system, thereby reducing the interference of external factors on the detection results.

[0031] 4. In order to enable the device to further clamp the grass roots and detect the hardness of the grass roots at the same time, a detection component is provided. The component, in conjunction with a short spring rod and a short splint and spikes, can fix the root system to a certain extent while avoiding excessive damage to the root system. The trigger sensor is located in the empty slot, which can sense and feedback information in time when the root system is subjected to force changes. The circular plate, special-shaped block, thick block, circular slot, tension spring, round block, and sliding splint structure adapt to the slight displacement of the root system during the force process through the elastic changes of the tension spring. The grass roots are placed in the connected slot to ensure the targeted detection, providing accurate data support for the study of the tensile mechanical properties of plant roots.

At the same time, in the short slide rail 510 structure on the outside of the long plate 59, one end of the long thread spring 524 is fixed to the inside of the short slide rail 510, and the other end is fixed to the fixed plate 523. The fixed plate 523 is connected to the movable clamp 512 through the short slider 511. Under the drive of the motor, a plurality of movable clamps 512 and fixed clamps 519 with similar structures are driven. Start exercising;

[0054] S4, when the movable clamping plates 512 and the fixed clamping plates 519 move, the spikes 85 on the surface of the short clamping plates 84 contact the two ends of the grass roots 9 as the clamping plates move. The design of the spikes 85 can penetrate the softer grass roots 9 more deeply, thereby firmly clamping the softer grass roots 9, so that the grass roots 9 will not easily slip out of the clamping plates during the subsequent tensile test. At the same time, when the grass roots 9 are harder, the harder grass roots 9 push the spikes 85 to make the short clamping plates 84 contact the trigger sensor 82, thereby judging the hardness of the grass roots 9;

[0055] S5. At the same time, when the grass root 9 is subjected to tension, when the grass root 9 has a tendency to slide forward due to the tension, it will drive the circular ring block 613 to move forward. The movement of the circular ring block 613 is transmitted to the clamping plate 64 through the small ball 69, the connecting rod 68, the large ball 67 and the square slider 63. Since the connecting slider 62 can slide in the connecting slide groove 61 outside the support block 513, when the circular ring block 613 moves, the multiple groups of clamping plates 64 slide relatively in the connecting slide groove 61 through the connecting slider 62. At the same time, the rubber plate 66 connected to the other end of the long spring rod 65 fixed on the outside of the clamping plate 64 further clamps the grass root 9 under the push of the long spring rod 65. The rubber plate 66 is made of soft rubber material, has good elasticity and elasticity, can better fit the shape of the grass root 9, and applies uniform pressure from the side to further enhance the fixing effect of the grass root 9. In addition, the multiple groups of long spring rods 65 The equally spaced linear array is arranged outside the clamping plate 64 to apply pressure to the grass root 9 from multiple positions simultaneously, thereby ensuring that the grass root 9 can be stably fixed in all directions;

[0056] S6. During the above-mentioned process of applying the pulling force and clamping the grass root 9, the electric slider 52 drives the square plate 53 to slide on the surface of the long slide rail 51. The sliding of the square plate 53 pushes the thrust measuring device 3 located outside the support plate 2. The thrust measuring device 3 can accurately measure the force generated in this process. This force is the tensile force of the grass root 9. By recording and analyzing the measurement data of the thrust measuring device 3, relevant information about the tensile mechanical properties of the grass root 9 can be obtained.

[0057] S7. After the tensile mechanical properties of the grass roots 9 are measured, when the device is not needed, the clamping block 76 in the support assembly 7 can be slid. By sliding the clamping block 76, with the support of the threaded spring rod 72, the connecting rod 68 and other related components can be supported, so that the device can remain in a stable idle state, and at the same time, it is prepared for the next measurement to avoid unnecessary displacement or damage of the components due to idleness.

[0058] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
