Description

Technical Field

[0001] The utility model relates to the technical field of collecting root secretions, in particular to a device for collecting potato root secretions. Background Art

[0002] Root secretions refer to various chemical substances released by plants into the growth medium through their roots during their growth. They are the chemical medium between the life activities of plant roots and the surrounding plants and soil ecological environment under a specific environment. Root secretions have a certain promoting effect on the growth and development of plants. Potato root secretions mainly include three parts: 1. Exudates are substances diffused outward from root cells, such as sugars, amino acids, etc.; 2. Metabolites actively secreted by root cells; 3. Substances produced by microorganisms after the decomposition residues fall off.

[0003] For example, a Chinese patent with the authorization announcement number CN208505632U discloses a plant root secretion collection device, including a base and a pillar, pillars are welded on both the left and right sides of the top of the base, a stud is provided on the top of the base, both the left and right sides of the stud are rotatably connected to the pillar through a bearing, the inner ring of the bearing is fixedly connected to the stud, and the outer ring of the bearing is fixedly connected to the pillar, and a rocker is provided at the right bottom end of the pillar on the right side. The plant root secretion collection device can compress and fix the plant through the arrangement of structures such as the through groove, the second slide groove, the arc-shaped clamping block, the compression spring and the pull rod.

[0004] In the above patent, the arc-shaped clamping block is pushed by the elastic force of the compression spring to clamp and fix the plant, but the clamping force of the arc-shaped clamping block on the plant in this patent is not easy to adjust, and it cannot be adaptively adjusted according to the size of the plant whose root secretions are to be collected. It is easy for the clamping force to be too large or too small. Excessive clamping force will cause damage to the plant, which is not conducive to the growth of the plant and affects the collection of the root secretions of the plant. Excessive clamping force will cause loose clamping, affecting the clamping and fixing effect of the plant and poor clamping stability. Utility Model Content

[0037] Reference Figure 1-6The utility model provides a potato root secretion collecting device: comprising a box body 1, a lifting mechanism is arranged on the top of the box body 1, a movable plate 2 is arranged on the lifting mechanism, a through hole 3 is opened at the middle position of the top of the movable plate 2, a mounting plate 4 is fixedly connected to the top of the movable plate 2 and located on both sides of the through hole 3, a driving mechanism and a guiding mechanism are arranged between the opposite sides of the two mounting plates 4, a PLC controller 5 is arranged on one of the mounting plates 4, two connecting plates 6 are arranged between the driving mechanism and the guiding mechanism, a telescopic rod 7 is fixedly connected to the opposite sides of the two connecting plates 6, a support plate 8 is fixedly connected to the other end of the telescopic rod 7, a spring 9 is arranged between the support plate 8 and the connecting plate 6 and located on the outside of the telescopic rod 7, a pressure sensor 10 is fixedly connected to the side of the support plate 8 away from the connecting plate 6, and an arc-shaped clamping block 11 is fixedly connected to the other side of the pressure sensor 10;

[0038] By using the driving mechanism, the guiding mechanism, the connecting plate 6, the telescopic rod 7, the spring 9, the pressure sensor 10, the PLC controller 5 and the arc-shaped clamping block 11 and other structures in coordination, the clamping force can be accurately controlled according to the size of the potato plant whose root secretions are to be collected, thereby avoiding the situation where the clamping force of the potato plant is too large or too small, and the clamping force can be automatically adjusted according to the growth of the potato plant in the later stage, so that the clamping force of the arc-shaped clamping block 11 on the potato plant is always maintained within an appropriate range, thereby avoiding the situation where the clamping force of the arc-shaped clamping block 11 on the plant increases due to the growth of the plant, thereby causing the plant to be clamped, ensuring that the potato plant can grow normally, and facilitating the collection of plant root secretions.

[0039] The driving mechanism includes a driving motor 12 fixedly mounted on one of the mounting plates 4 , the output end of the driving motor 12 is fixedly connected to a bidirectional lead screw 13 , and the outer surface of the bidirectional lead screw 13 is threadedly connected to two threaded driving blocks 14 .

[0040] The guide mechanism comprises a guide rod 15 fixedly mounted between the two mounting plates 4, and two guide rings 16 are movably sleeved on the outer surface of the guide rod 15.

[0041] The two guide rings 16 are fixedly connected to the two connecting plates 6 respectively, and the other ends of the two connecting plates 6 are fixedly connected to the two threaded driving blocks 14 respectively.

[0042] A support frame 17 is fixedly connected to the inner wall of the box body 1, a support frame 2 18 is overlapped on the top of the support frame 17, a filter frame 19 is fixedly connected to the bottom of the support frame 18, a handle 20 is fixedly connected to the top of the support frame 18, and the cross-sectional dimension of the movable plate 2 is smaller than the cross-sectional dimension of the filter frame 19.

[0043] One side of the box body 1 is fixedly connected with a collecting pipe 21, and a drainage member 22 is arranged on the collecting pipe 21. The drainage member 22 adopts a pop-up button valve, a pull-down valve or a knob valve.

[0044] The lifting mechanism includes a fixed frame 23 fixedly mounted on the top of the box body 1, an electric telescopic rod 24 and a second guide ring 25 are fixedly mounted on the fixed frame 23, the telescopic end of the electric telescopic rod 24 is fixedly connected to the movable plate 2, and a second guide rod 26 is movably inserted inside the second guide ring 25, and the bottom end of the second guide rod 26 is fixedly connected to the top of the movable plate 2;

[0045] By starting the electric telescopic rod 24 to extend it downward, the movable plate 2 and the potatoes whose root secretions are to be collected are driven to move downward synchronously, so that the height of the potato plants in the box 1 can be adjusted, so that the staff can inject an appropriate amount of culture solution into the box 1 according to the size of the plant and the length of the root system, thereby improving the practicality of the device. In addition, through the coordinated use of the guide rod 26 and the guide ring 25, the movable plate 2 can be limited when it moves up and down, so as to improve the stability of the movable plate 2 when moving.

[0046] Working principle: When in use, the staff first passes the root system of the potato plant through the opening 3 and makes the root system of the potato plant located under the movable plate 2, and then starts the drive motor 12. The output end of the drive motor 12 rotates clockwise to drive the bidirectional screw rod 13 to rotate, and then under the cooperation of the guide rod 15 and the guide ring 16, the connecting plate 6 and the threaded drive block 14 are limited, so that the two threaded drive blocks 14 move to the opposite side along the axial direction of the bidirectional screw rod 13, and then drive the two arc-shaped clamping blocks 11 to move. When the two arc-shaped clamping blocks 11 move to abut against the potato plant, the two connecting plates 6 continue to move to the opposite side, so that the connecting plates 6 and the arc-shaped clamping blocks 11 are in contact with the potato plant. The spacing between the clamping blocks 11 is reduced, and the spring 9 is squeezed, and then the arc-shaped clamping block 11 is squeezed by the elastic force of the spring 9, so that the two arc-shaped clamping blocks 11 clamp and fix the potato plants, and through the setting of the pressure sensor 10, the clamping force of the arc-shaped clamping block 11 on the potato plants can be monitored, and the monitored data is transmitted to the PLC controller 5, and the data is integrated and analyzed by the PLC controller 5. When the clamping force of the arc-shaped clamping block 11 on the potato plants reaches a preset value, the driving motor 12 is turned off by the PLC controller 5, thereby realizing precise control of the clamping force, and avoiding the situation where the clamping force of the potato plants is too large or too small;

[0047] After the potatoes whose root secretions are to be collected are clamped and fixed, the height of the potato plants in the box 1 is adjusted according to the size of the potato plants and the length of the root system, thereby indirectly adjusting the amount of subsequent culture solution injection, and the electric telescopic rod 24 is started to extend downward, driving the movable plate 2 and the potatoes whose root secretions are to be collected to move downward synchronously, thereby adjusting the height of the potato plants in the box 1, so that the staff can inject an appropriate amount of culture solution into the box 1 according to the size of the plants and the length of the root system, thereby improving the practicality of the device;

[0048] According to the size of the potato plant and the length of the root system, after the potato plant is adjusted to a suitable height in the box 1, the staff injects a proper amount of culture solution into the box 1. In the process of collecting the root secretions of the potato plant, the potato plant will continue to grow with the passage of time. After the plant grows, it becomes thicker and will stretch the arc-shaped clamping blocks 11 clamped on both sides of the potato plant to the separated side. The spring 9 is further compressed, causing the clamping force of the arc-shaped clamping block 11 on the potato plant to increase. At this time, when the clamping force is greater than the preset value, the PLC controller 5 starts to drive the spring. When the arc-shaped clamping block 11 reaches 12, the output end of the arc-shaped clamping block 11 rotates counterclockwise, driving the two connecting plates 6 to move to the separated side, until the clamping force of the arc-shaped clamping block 11 on the potato plant is restored to the preset value, the PLC controller 5 turns off the driving motor 12, so that the clamping force of the arc-shaped clamping block 11 on the potato plant can be automatically adjusted according to the growth of the potato plant during the collection of the root secretions of the potato plant, so that the clamping force of the arc-shaped clamping block 11 on the potato plant is always kept within an appropriate range, avoiding the situation that the clamping force of the arc-shaped clamping block 11 on the plant increases due to the growth of the plant, causing the plant to be clamped;

[0049] The culture solution in the box 1 passes through the filter frame 19 to soak the roots of the potato plants. The secretions of the roots of the potato plants are in the culture solution. When the secretions need to be extracted, the drainage piece 22 is opened to make the collecting tube 21 in an open state. The culture solution in the box 1 flows out from the collecting tube 21. The outflowing culture solution is collected using a container to extract the secretions.
