[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a plant pull-out testing device, such as... Figure 1-6 As shown, the plant pull-out testing device includes: a push-pull force gauge body 2 mounted on a placement frame 1 for testing the pull-out force of plant roots; a mounting frame 3 mounted below the placement frame 1, the mounting frame 3 being connected to the push-pull force gauge body 2, and the mounting frame 3 being provided with a clamping ring 4 for holding the main stem of the plant; and a pull-out mechanism mounted on the placement frame 1 for driving the push-pull force gauge body 2 to move vertically to perform a pull-out test on the plant.

[0025] In this embodiment, when conducting a pull-out test on the root grip of the plant, the push-pull force gauge body 2 is model NK-10. The push-pull force gauge body 2 typically consists of a spring system and a pointer. When an external force acts on the spring, the spring deforms (elongates or shortens). This deformation is proportional to the magnitude of the external force. According to Hooke's Law, the magnitude of the external force can be calculated by measuring the deformation of the spring. The pointer indicates the magnitude of the force. When an external force acts on the spring, the deformation of the spring causes the pointer to deflect. The position where the pointer stops on the scale is the value of the external force. By reading the scale indicated by the pointer, the magnitude of the force acting on the object can be directly determined. The working principle of the push-pull force gauge body 2 is existing technology and will not be elaborated upon here. The mounting bracket 3 is placed on one side of the plant's main stem, and the plant is supported by two clamps 4. The plant's main stem is clamped, and then the two push-pull force gauge bodies 2 on the placement frame 1 are connected to the mounting frame 3. Then, the operator operates the pulling mechanism to move the push-pull force gauge bodies 2 vertically upward, thereby pulling the plant's main stem. The push-pull force gauge bodies 2 can test the pulling force on the plant's root system, thus testing the plant's root grip strength. During the pulling process, the pulling mechanism can provide the plant with a vertically upward pulling force, avoiding any tilting of the force direction during the pulling test, thereby improving the accuracy of the plant pulling test. Through the entire device, the plant can be pulled, and during the pulling test, it can provide the plant with a vertically upward pulling force, avoiding any tilting of the force direction during the pulling test, thereby improving the accuracy of the plant pulling test.

[0026] In a further preferred embodiment of the present invention, the pulling mechanism includes: a connecting frame 5 assembled on one side of the placement frame 1; a threaded rod 6 rotatably mounted on the connecting frame 5 via a damping shaft, wherein a connecting block 7 is threadedly mounted on the threaded rod 6, and the connecting block 7 is fixedly connected to the placement frame 1.

[0027] In this embodiment, when using the pull-out mechanism, the operator rotates the threaded rod 6. A limit rod is fixedly installed on the connecting frame 5. The limit rod and the connecting block 7 are slidably connected. The limit rod limits the connecting block 7, thereby allowing the threaded rod 6 to stably drive the connecting block 7 to move. This allows the push-pull force gauge body 2 to move vertically upward, thus performing a pull-out test on the plant's main stem. When viewed from the side, it provides a vertically upward pull-out force to the plant, avoiding any tilting of the force direction during the pull-out test, thereby improving the accuracy of the plant pull-out test.

[0028] In a further preferred embodiment of the present invention, the mounting frame 3 and the clamping ring 4 are provided with a clamping mechanism for clamping the main stem of the plant by driving the two clamping rings 4 to move relative to each other. The clamping mechanism includes: a lead screw 8 rotatably mounted on the mounting frame 3 via a damping shaft; and two mounting blocks 9 threadedly mounted on the lead screw 8, the two mounting blocks 9 being fixedly connected to the two clamping rings 4 respectively.

[0029] In this embodiment, when the mounting frame 3 is placed on one side of the plant trunk, the operator rotates the screw 8. A limiting rod is fixedly installed on the mounting frame 3. The limiting rod and two mounting blocks 9 are slidably connected. The limiting rod limits the mounting blocks 9. The screw 8 drives the two clamping rings 4 to move relative to each other, thereby clamping the plant trunk. Then, the two push-pull force gauge bodies 2 are connected to the mounting frame 3, which facilitates the pull-out test of the plant.

[0030] In a further preferred embodiment of this utility model, the lead screw 8 is provided with two opposite threads, and the two mounting blocks 9 are respectively threaded onto the two opposite threads of the lead screw 8.

[0031] In this embodiment, two mounting blocks 9 are respectively threaded onto two opposite threads of the lead screw 8, which facilitates the lead screw 8 to drive the two clamping rings 4 to move relative to each other and clamp the main stem of the plant.

[0032] In a further preferred embodiment of the present invention, a support frame 10 for supporting the connecting frame 5 is provided at the bottom of the connecting frame 5. The support frame 10 includes a support rod 1001 and a connecting shell 1002. An adjustment mechanism is provided on the support rod 1001 and the connecting shell 1002 for adjusting the placement position of the connecting shell 1002 on the support rod 1001.

[0033] In this embodiment, when conducting pull tests on different plants, the staff can adjust the placement of the connecting shell 1002 on the support rod 1001 by adjusting the mechanism according to the plant's condition and actual usage needs, thereby adjusting the overall usage height of the support frame 10, making it more flexible to use.

[0034] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a mounting shell 11 fixedly mounted on the connecting shell 1002; a locking rod 12 slidably mounted on the mounting shell 11 and the connecting shell 1002, wherein a stop block 13 is fixedly sleeved on the locking rod 12 and a spring 15 is sleeved on the locking rod 12; and a plurality of slots 16 formed on the support rod 1001, wherein the plurality of slots 16 are adapted to the locking rod 12.

[0035] In this embodiment, when using the adjustment mechanism, pulling the lever 12 causes the stop block 13 to compress the spring 15, disengaging the end of the lever 12 from the corresponding slot 16. Then, the approximate position of the connecting shell 1002 on the support rod 1001 is adjusted, and then the relative position of the connecting shell 1002 and the support rod 1001 is finely adjusted, that is, the corresponding slot 16 is adjusted to one side of the end of the lever 12. Then, the lever 12 is released, the spring 15 returns to its original position, thereby connecting the end of the lever 12 with the corresponding slot 16, thus fixing the adjusted connecting shell 1002 on the support rod 1001, which facilitates the adjustment of the overall usage height.

[0036] In a further preferred embodiment of the present invention, a pedal 17 is fixedly installed on one side of the support rod 1001, and the pedal 17 is used by staff to step on the plant when conducting pull-out tests.

[0037] In this embodiment, when the staff conducts a pull-out test on the plant, they step on the pedal 17, which fixes the support rod 1001 to the ground, making it easier to conduct the pull-out test on the plant.

[0038] In a further preferred embodiment of this utility model, two connecting rings 301 are fixedly installed on the mounting bracket 3, and the two connecting rings 301 are respectively adapted and connected to the two push-pull force gauge bodies 2.

[0040] In summary, compared with related technologies, this device can perform pull-out tests on plants and provide a vertically upward pulling force during the test, avoiding any tilting of the force direction and thus improving the accuracy of the plant pull-out test.
