Description

Technical Field

[0001] This utility model relates to the field of root sampling technology, specifically to a digging device for observing and sampling crop root growth. Background Technology

[0002] Plant root sampling is an important part of forestry surveys. The sampled roots are used to assess the forest's productivity, facilitating further work. With socio-economic development and increasing focus on ecology, plant root analysis and testing are needed in various fields, including forestry surveys, agricultural production, and plant growth. Plant root sampling devices are tools used to obtain plant root samples. Plant root sampling involves two steps: soil sampling and root sieving. Current root collection methods use two separate devices, making the sampling equipment inconvenient to carry, cumbersome to operate, and adding to the workload of staff.

[0003] A search revealed that Chinese Patent CN212780037U discloses a plant root sampling device, including a handle, a connecting rod, a support mechanism fixedly connected to the bottom of the connecting rod, a sampling mechanism movably connected to the support mechanism and rotating around the support mechanism, a drive mechanism for driving the sampling mechanism to rotate, a sieving mechanism sleeved on the outside of the sampling mechanism to separate the soil and roots, a limiting mechanism for controlling the movement position of the sieving mechanism, and a sealing mechanism for sealing the sieving mechanism. The sampling mechanism and drive mechanism of this patent are designed so that the drive mechanism drives the sampling mechanism to rotate, which facilitates sampling of the roots by entering the ground, avoiding the time-consuming and laborious process of workers pressing the tool hard on the ground. The sieving mechanism facilitates the rapid separation of soil and roots within the sampling mechanism, making the operation simple and the work efficiency high.

[0004] After the above-mentioned device takes a sample, it removes the soil from the roots by vibration. However, if the soil is sticky and dense, it is difficult to remove the soil from the roots by vibration because the soil itself has high adhesion. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5 In this embodiment of the invention, a digging device for observing and sampling crop root growth includes:

[0037] Support 1 is a steel structure made of corrosion-resistant material. Support 1 consists of a square plate and four support rods that are fixed at the four corners of the square plate.

[0038] The movable plate 5 is slidably sleeved on each support rod. It can be seen that the movable plate 5 can only move vertically within the bracket 1. The square plate is equipped with a lifting assembly that allows the movable plate 5 to move vertically along the support rod.

[0039] The excavating cylinder 11 has a first rotating hole on the outer side of the moving plate 5. One end of the excavating cylinder 11 is rotatably installed in the first rotating hole. Thus, the excavating cylinder 11 can rotate axially within the moving plate 5. The top of the square plate is provided with a rotating assembly that allows the excavating cylinder 11 to rotate.

[0040] The top of the square plate of the diversion pipe has a fixing hole. The main branch of the diversion pipe is fixedly installed in the fixing hole. Each branch of the diversion pipe is fixed with a vertical pipe connected to it. One end of the vertical pipe is connected to the nozzle 20 through the hose 19. Each branch of the diversion pipe is provided with a swing assembly that makes the nozzle 20 swing.

[0041] Water pump 3, the outer casing of water pump 3 is fixed on the square plate, the outlet end of water pump 3 is connected to the main branch of the branch pipe, and the inlet end of water pump 3 is connected to the external water source (the external water source can be a water tank containing clean water).

[0042] The technical solution of this utility model can be understood from the above connection relationship: the support 1 is placed on the ground, and the support 1 is moved so that the crop to be sampled is located below the digging cylinder 11. The rotating component allows the digging cylinder 11 to rotate axially within the moving plate 5. The lifting component allows the moving plate 5 to move down along the support rod. When the digging cylinder 11 contacts the ground, the water pump 3 is turned on. The water outlet of the water pump 3 is introduced into the diversion pipe. The diversion pipe diverts the water into each vertical pipe and then sprays it out from the nozzle 20. The swing component makes the nozzle 20 swing. The water sprayed from the nozzle 20 disperses the soil and exposes the crop roots, which can then be rinsed.

[0043] Specifically, in conjunction with the appendix Figure 2 As shown, the lifting assembly includes:

[0044] The limiting plate 6 is located below the moving plate 5, and the four corners of the limiting plate 6 are fixed with support rods. The limiting plate 6 is set to limit the downward movement range of the moving plate 5.

[0045] The threaded rod 4, the square plate, and the limiting plate 6 are all provided with second rotating holes on their outer sides. The two ends of the threaded rod 4 are respectively rotatably installed in the second rotating holes. Thus, the threaded rod 4 can only rotate axially in the square plate and the limiting plate 6. The outer side of the moving plate 5 is provided with threaded holes. The outer side of the threaded rod 4 is installed in the threaded holes by threads. When the threaded rod 4 rotates axially, the threaded rod 4 causes the moving plate 5 to slide on the support rod through the threaded transmission.

[0046] The first servo motor 2 has its housing fixed on the square plate. The output shaft of the first servo motor 2 is coaxially fixed with the threaded rod 4. The first servo motor 2 causes the threaded rod 4 to rotate axially through the output shaft.

[0047] Specifically, in conjunction with the appendix Figure 1-2 As shown, the rotating assembly includes:

[0048] The worm 8 has two bearing seats 9 fixed on the top of the square plate. The two ends of the worm 8 are rotatably mounted on the bearing seats 9. The worm 8 can only rotate axially in the square plate.

[0049] The worm gear 10 is coaxially fixed with the digging cylinder 11. The worm 8 meshes with the worm gear 10, and the worm 8 drives the digging cylinder 11 to rotate through the worm gear 10.

[0050] The second servo motor 7 has its housing fixed on the square plate. The output shaft of the second servo motor 7 is coaxially fixed with the worm gear 8. The second servo motor 7 causes the worm gear 8 to rotate axially through its output shaft.

[0051] Specifically, in conjunction with the appendix Figure 3 As shown, the outer side of the excavation cylinder 11 has multiple through holes 13. In order to prevent water from accumulating inside the excavation cylinder 11, the through holes 13 can effectively draw water out. At the same time, after the soil is lost with the water, the excavation cylinder is easier to insert downwards.

[0052] Specifically, in conjunction with the appendix Figure 3 As shown, the bottom end of the excavation cylinder 11 is provided with multiple serrations 12, and the multiple serrations 12 are distributed in a ring at equal intervals along the central axis of the excavation cylinder 11. The serrations 12 are provided to facilitate the insertion of the excavation cylinder 11 into the ground.

[0053] Specifically, in conjunction with the appendix Figure 3-5As shown, the swing assembly includes:

[0054] The first fixing plate 15 is fixed to the diversion pipe;

[0055] The second fixed plate 16 has multiple support plates 21 rotatably mounted on its bottom. A connecting rod 17 is rotatably mounted on the outer side of the support plate 21. A rotating plate 18 is rotatably mounted on one end of the connecting rod 17. The two ends of the rotating plate 18 are respectively rotatably mounted on the vertical pipe and the nozzle 20. During the up and down movement of the second fixed plate 16, the second fixed plate 16 causes the rotating plate 18 to swing back and forth through the connecting rod 17.

[0056] The electric push rod 14 has its outer shell fixed to the first fixed plate 15 and its telescopic end fixed to the second fixed plate 16.

[0057] Working principle: The support frame 1 is erected on the ground, and simultaneously moved so that the crop to be sampled is positioned below the digging cylinder 11. The second servo motor 7 is activated, and its output shaft drives the worm gear 8 axially. The worm gear 8, through its meshing worm wheel 10, drives the digging cylinder 11 to rotate. The first servo motor 2 is activated, and its output shaft causes the threaded rod 4 to rotate axially. When the threaded rod 4 rotates axially, it causes the moving plate 5 to slide downwards on the support rod through threaded transmission. When the nozzle 11 comes into contact with the soil, the water pump 3 is turned on. The water outlet of the water pump 3 is introduced into the diversion pipe, which then diverts the water into each vertical pipe and sprays it out from the nozzle 20. The electric push rod 14 is activated, and the electric push rod 14 reciprocates. The electric push rod 14 drives the second fixed plate 16 to move up and down. During the up and down movement of the second fixed plate 16, the second fixed plate 16 causes the rotating plate 18 to swing back and forth through the connecting rod 17. The water sprayed from the nozzle 20 disperses the soil, exposing the crop roots, which can then be rinsed.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
