Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seedling cultivation and planting, in particular to a water-saving seedling root depth washing and residue-free disinfection integrated device. BACKGROUND

[0002] In the field of seedling cultivation and planting, the health of seedling roots is directly related to the survival rate of seedlings and the quality of subsequent growth and development. During the growth of seedlings, the roots will be in close contact with the soil. Various impurities, bacteria and insect eggs contained in the soil are easily attached to the seedling roots. If these harmful substances are not treated in time and effectively, they will enter the new planting environment with the roots after the seedlings are transplanted, which may not only cause diseases and insect pests of seedlings, leading to poor growth or even death of seedlings, but also damage the surrounding soil ecology and affect the normal growth of other plants, thereby causing serious economic losses to related industries such as forestry and agriculture. Therefore, it is necessary to scientifically and reasonably treat seedling roots.

[0003] However, the washing and disinfection of seedling roots are usually two separate links. The traditional washing method is mostly simple and extensive, which generally only involves soaking or simply washing the seedling roots with water. This method cannot completely remove stubborn impurities and bacteria attached to the roots, and the washing effect is poor. In the disinfection link, the common method is to soak or spray the seedlings with disinfectant. However, these methods often have problems such as uneven disinfection and residue, and cannot guarantee comprehensive and residue-free disinfection of seedling roots. In addition, the existing treatment methods also have problems such as serious waste of water resources, complicated operation and low efficiency, which cannot meet the needs of large-scale seedling planting production. Therefore, we propose a water-saving seedling root depth washing and residue-free disinfection integrated device. SUMMARY

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7This invention provides a technical solution: a water-saving seedling root deep washing and residue-free disinfection integrated device, including a mounting base plate 1, a washing cylinder 2 at the upper end of the mounting base plate 1, a mounting top plate 3 at the upper end of the washing cylinder 2, a lifting frame 4 at the lower end of the mounting top plate 3, the lifting frame 4 being located at the upper end of the washing cylinder 2, a connecting column 5 being fixedly connected to the lower end of the mounting top plate 3, the connecting column 5 being located inside the lifting frame 4, a rotating disk 8 being fixedly connected to one end of the connecting column 5, a driving disk 11 being located on one side of the rotating disk 8, an arc-shaped groove 9 being opened on the outer side of the rotating disk 8, and a turning groove 10 being opened on the outer side of the rotating disk 8, with multiple arc-shaped grooves 9 and turning grooves 10 being provided, and evenly distributed in a circular array.

[0019] An arc-shaped plate 15 is fixedly connected to the lower end of the drive disk 11. One side surface of the arc-shaped plate 15 is in contact with the inner side of the arc-shaped groove 9. A toggle post 16 is provided on one side of the arc-shaped plate 15. One end of the toggle post 16 is fixedly connected to the lower surface of the drive disk 11. The toggle post 16 and the toggle groove 10 are mutually adapted. While the drive disk 11 drives the arc-shaped plate 15 and the toggle post 16 to rotate, the cooperation between the toggle post 16 and the toggle groove 10 and the arc-shaped plate 15 and the arc-shaped groove 9 are used to jointly realize that the drive disk 11 drives the rotating disk 8 to rotate. While the rotating disk 8 drives the protective part 17 to rotate, it is not only conducive to the loading and unloading rotation operation of the protective part 17, but also conducive to the washing and selection of seedlings fixed inside the protective part 17.

[0020] A rotating bevel gear 12 is fixedly connected to the upper end of the drive disc 11. A drive bevel gear 13 is provided on one side of the rotating bevel gear 12. The drive bevel gear 13 and the rotating bevel gear 12 are movably connected. A first motor 14 is fixedly connected to the outside of the washing cylinder 2. The output end of the first motor 14 is fixedly connected to one side surface of the drive bevel gear 13. The first motor 14 is electrically connected to an external controller. The controller controls the working state of the first motor 14 at the same time. When the first motor 14 is working, its output end drives the drive bevel gear 13 to rotate. At the same time, the meshing connection between the drive bevel gear 13 and the rotating bevel gear 12 drives the rotating bevel gear 12 and the drive disc 11 to rotate.

[0021] The inner side of the washing and screening cylinder 2 is provided with a protective component 17, which includes a protective cylinder 18. There are two protective cylinders 18 arranged symmetrically. The lower end of the protective cylinder 18 is provided with a coupling gear 19. The two corresponding coupling gears 19 are adapted to each other and the two corresponding coupling gears 19 are coupled into a whole, which facilitates the rotation of the entire protective component 17.

[0022] A protective pad 20 is fixedly connected to the inner side of the protective cylinder 18. Three protective pads 20 are arranged in a linear array and evenly distributed. A splicing bolt 21 is fixedly connected to one side of the protective cylinder 18. A splicing hole 22 is opened on one side surface of the protective cylinder 18. Between two corresponding protective cylinders 18, the splicing bolt 21 fixedly connected to one side and the splicing hole 22 opened on one side are mutually compatible. The seedling is placed between two protective cylinders 18, and the protective pad 20 is used to contact the seedling to avoid damage to the seedling during the overall operation.

[0023] A splicing plate 23 is fixedly connected to one side surface of the protective cylinder 18, and a splicing groove 24 is opened on one side surface of the protective cylinder 18. Between two corresponding protective cylinders 18, the splicing plate 23 fixedly connected to one side and the splicing groove 24 opened on one side are mutually adapted. By using the cooperation between the splicing bolt 21 and the splicing hole 22, and by using the cooperation between the splicing plate 23 and the splicing groove 24, the splicing between the two protective cylinders 18 is convenient, and the seedlings are stably placed between the two protective cylinders 18.

[0024] A limiting groove 25 is provided on the inner side of the lifting frame 4. The upper end of the protective component 17 is movably disposed inside the limiting groove 25. The limiting groove 25 stabilizes the upper position of the protective component 17 and related components, effectively guiding their movement direction and preventing misalignment or tilting. A fixing plate 26 is fixedly connected to the outer side of the lifting frame 4. Two fixing plates 26 are provided and symmetrically distributed. A cylinder 27 is provided at the lower end of the fixing plate 26. One end of the cylinder 27 is fixedly connected to the outer surface of the washing cylinder 2, and the output end of the cylinder 27 is fixedly connected to one side surface of the fixing plate 26. The two cylinders 27 are electrically connected to an external controller, which controls the working state of the cylinders 27 and controls the lifting frame 4 and its components. The height position of the movable protective component 17 is such that when the cylinder 27 drives the lifting frame 4 and the movable protective component 17 to the highest point, the inlet 28 and outlet 29 facilitate the replacement and movement of the movable protective component 17, thus facilitating the overall loading and unloading operation and the continuous operation of the device. When the cylinder 27 drives the lifting frame 4 and the movable protective component 17 to the lowest point, the rotating disk 8, the bevel gear disk 30 and the splicing gear 19 work together to drive the protective component 17 to rotate as a whole. At the same time, the centrifugal impeller 32 agitates the washing liquid inside the washing cylinder 2, facilitating the overall washing of the seedling roots, improving work efficiency, reducing resource waste, and achieving water conservation.

[0025] A feed inlet 28 is provided on one side of the lifting frame 4, and a discharge outlet 29 is provided on the other side. A centrifugal impeller 32 is provided inside the washing cylinder 2, and a bevel gear disk 30 is fixedly connected to the upper end of the centrifugal impeller 32. An auxiliary pile 31 is provided inside the washing cylinder 2. The pile rod provided at the upper end of the auxiliary pile 31 is adapted to the outer side of the splicing gear 19 to facilitate the rotation of the splicing gear 19 and related components, and at the same time limit it to prevent deflection and misalignment, which would affect the efficiency of the device. A second motor 33 is provided at the lower end of the washing cylinder 2. The second motor 33 is fixedly connected to one side surface of the mounting base plate 1, and the output end of the second motor 33 is fixedly connected to one side of the centrifugal impeller 32. On one side of the washing and selection cylinder 2, a material replacement pipe 34 is fixedly connected. The material replacement pipe 34 is used to replace the washing liquid inside the washing and selection cylinder 2. The second motor 33 is electrically connected to an external controller. The external controller controls the operating status of the second motor 33. When the second motor 33 starts, it drives the centrifugal impeller 32 fixed at its output end to rotate inside the bottom side of the washing and selection cylinder 2. At the same time, the rotation can drive the washing liquid placed inside the washing and selection cylinder 2 to rotate. Simultaneously, the passive rotation of the protective part 17 and related components is used. The two rotate in opposite directions, so that the washing liquid can flow to the root position of the seedling root system to the maximum extent, and at the same time, the root of the seedling root system is cleaned to the maximum extent.

[0026] A guide pipe 6 is fixedly connected to the inner side of the connecting column 5. A guide nozzle 7 is provided at one end of the guide pipe 6. The guide nozzle 7 is located at the lower end of the rotating disk 8. The other end of the guide nozzle 7 extends to the upper end of the mounting top plate 3. One end of the guide pipe 6 is connected to the external infusion pipe. By using the infusion pipe and the guide pipe 6 in conjunction, the guide nozzle 7 is used to spray the seedling roots transported from the outside with disinfectant into the interior of the washing and sorting cylinder 2 and onto the roots of the seedlings fixed inside the protective component 17.

[0027] Before using the entire device, the cylinder 27 is controlled by an external controller to raise the lifting frame 4 and the protective component 17 to the highest position. The seedling is placed between the two protective cylinders 18. The protective cylinders 18 are assembled by the cooperation of the splicing bolt 21 and the splicing hole 22, and the splicing plate 23 and the splicing groove 24. The protective pad 20 protects the seedling. Then, the upper end of the protective component 17 is placed into the limiting groove 25 through the inlet 28. The lower end of the protective component 17 is set inside the arc groove 9. The first motor 14 is started, and the drive bevel gear 13 and the rotating bevel gear 12 drive the drive disk 11 to rotate. Through the cooperation of the arc plate 15 and the arc groove 9, and the actuating column 16 and the actuating groove 10, the rotating disk 8 drives the protective component. Rotating cylinder 27 enables simultaneous loading and unloading of multiple seedlings for washing and selection. Then, cylinder 27 drives protective component 17 to descend to its lowest point. Simultaneously, the second motor 33 drives centrifugal impeller 32 to rotate and agitate the washing liquid. Protective component 17 and related components utilize the cooperation between discharge port 29, bevel gear disc 30, and auxiliary pile 31. Protective component 17 and centrifugal impeller 32 rotate in opposite directions, enhancing the overall washing and selection effect. After washing and selection, external disinfectant is sprayed onto the root system of the seedlings through guide pipe 6 and guide nozzle 7 for residue-free disinfection. Finally, cylinder 27 drives protective component 17 to rise to its highest point, and the seedlings are removed from discharge port 29. At the same time, the washing liquid is replaced through material replacement pipe 34 to facilitate the washing and selection operation of the next batch.
