Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, specifically to a seed dressing device for virus-free potato planting. Background Technology

[0002] The seed treatment device for potato cultivation is designed to treat potato seeds by evenly coating them with pesticide solution before planting, effectively preventing pests and diseases and enhancing crop resistance. However, this device has encountered a problem in practical application: when seeds enter the treatment device, they often pile up due to gravity. This piling up prevents the lower seeds from fully contacting the pesticide solution, resulting in uneven coverage; while the upper seeds may suffer from pesticide damage due to excessive contact with the solution, affecting germination rate and early growth. Summary of the Invention

[0003] In view of this, the present disclosure provides a seed dressing device for virus-free potato planting, which at least partially solves the problems existing in the prior art.

[0004] This application discloses a seed treatment device for virus-free potato cultivation, comprising:

[0005] Seed inlet, used to introduce seeds into the device;

[0006] A baffle, tilted and positioned below the seed inlet, is used to disperse the seeds and prevent them from piling up.

[0007] The mixing drum, connected to the seed inlet, is used to hold seeds and pesticide solution, and has an internal stirring mechanism;

[0008] A dispersing disc, positioned below the baffle, is used to evenly distribute the incoming seeds;

[0009] The outlet funnel, located at the bottom of the mixing cylinder, is used to discharge the treated seeds; among which...

[0010] The baffle is provided with multiple guide grooves to guide the seeds to slide along the grooves and disperse into the dispersion disc; and

[0014] In one specific embodiment, the top of the mixing cylinder is provided with a ring-shaped spray pipe, and the bottom end of the spray pipe is arrayed with multiple sets of spray heads, which are used to spray the liquid medicine.

[0015] In one embodiment, each of the spray heads includes multiple water outlets with different spray orifice diameters.

[0016] In one specific embodiment, the annular spray pipe is threaded onto the top of the mixing cylinder.

[0017] In one specific embodiment, the bottom of the outlet funnel is provided with a conveying cylinder, and a spiral conveying shaft is provided inside the conveying cylinder. The spiral conveying shaft rotates under the drive of a drive motor, so that the seeds are gradually discharged.

[0018] In one specific embodiment, the width of the baffle is 10% to 30% larger than the width of the seed inlet.

[0019] In one specific embodiment, the stirring mechanism includes a stirring shaft located in the middle of the mixing cylinder and stirring blades fixed on the stirring shaft.

[0020] In one specific embodiment, a stirring motor is connected to the top of the stirring shaft, and the stirring motor drives the stirring shaft to stir the seeds.

[0021] This disclosure provides a seed-mixing device for virus-free potato cultivation, comprising: a seed inlet for introducing seeds into the device; a baffle, inclined and positioned below the seed inlet, for dispersing seeds and preventing seed stacking; a mixing cylinder connected to the seed inlet for holding seeds and pesticide solution, and having an internal stirring mechanism; a dispersing disc positioned below the baffle for evenly distributing the entering seeds; and an outlet funnel located at the bottom of the mixing cylinder for discharging the treated seeds. The baffle has multiple guide grooves to guide the seeds to slide along the grooves into the dispersing disc; and the surface of the dispersing disc has multiple longitudinal grooves. This solution addresses the problem that seeds tend to stack due to gravity after entering the mixing device, leading to insufficient contact between the lower layer of seeds and the pesticide solution during mixing, while the upper layer of seeds may suffer phytotoxicity due to excessive contact.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0029] like Figure 1 As shown, a seed mixing device for virus-free potato planting according to this application includes a seed inlet 1, a baffle 2, a mixing cylinder 3, a dispersing disc 4, and an outlet funnel 5.

[0030] The seed inlet 1 is located at the very top of the device, and its function is to input the virus-free potato seeds to be treated from the outside into the device. This component should be positioned at the highest point of the entire system to ensure that the seeds can smoothly enter the main body of the device under gravity without the need for additional mechanical power. It can be a structure with a large opening to accommodate different numbers and sizes of seed potatoes to be treated.

[0031] Following this is the baffle 2 structure connecting the lower part of the seed inlet 1 (such as...). Figure 4(As shown). The baffle 2 is set at a certain angle downwards, which allows the baffle 2 to act as a buffer surface to guide the introduced seed cluster to spread along this inclined surface and slowly move downwards towards the dispersion disk 4 area, avoiding direct impact of the seeds and excessive stacking. The baffle 2 has a relatively wide dimension, with its width exceeding the range of the seed inlet 1 located above, and it spreads out laterally in physical space to achieve the above-mentioned dispersion task.

[0032] The mixing cylinder 3 forms the main spatial framework of this device and, together with the aforementioned seed inlet 1 and other components to be described later, constitutes a complete closed system. The mixing cylinder 3 has sufficient capacity to receive the potatoes transported in through the previous steps. Internally, it is equipped with a stirring mechanism for agitating the contents to achieve mixing.

[0033] When the virus-free potato seeds reach the dispersing disc 4, located further downstream of baffle 2, after the aforementioned process, it further ensures that the raw materials can be distributed as evenly as possible within the subsequent working area. Because the mixing cylinder 3 has a relatively large internal diameter, at least twice the diameter of the dispersing disc 4, it provides ample operating space for the latter to rotate freely. This geometric design aims to ensure that each seed can gradually transition to the next process even with slight obstruction or collision.

[0034] The bottom of the device is equipped with an outlet funnel 5. This part is responsible for guiding the product that has completed the designated processing stage to the final discharge route. Considering that the density of the material may gradually increase over time during the material transfer process, in order to prevent blockages in the discharge stage and ensure that only an appropriate amount of product flows out in an orderly manner within each unit of time to maintain a stable working state, the size of the outlet funnel 5 is set to be relatively small.

[0035] In one embodiment, continue to refer to Figure 4 The baffle 2 of the seed mixing device for virus-free potato cultivation disclosed in this application is provided with multiple guide grooves 6 to guide the seeds to slide down along the grooves into the dispersing tray 4. This design further prevents the seeds from piling up during the sliding process, improving the mixing effect. Specifically, the multiple guide grooves 6 are arranged along the length of the baffle 2 and extend from the top of the baffle 2 towards the dispersing tray 4, forming an effective path that allows each entering seed to slide smoothly down in a separate channel. The design of these guide grooves 6 ensures that each seed can reach the surface of the dispersing tray 4 along the expected trajectory.

[0036] The baffle 2 is installed directly below the seed inlet 1, and its width is greater than that of the seed inlet 1, thus effectively covering all seed flow paths from the seed inlet 1. Furthermore, the baffle 2 is arranged at an angle, which helps the seeds slide quickly and evenly downwards along the slope under their own weight. Each guide groove 6 on the baffle 2 has a certain inclination, consistent with the overall angle of the baffle 2, further enhancing this uniform distribution effect. Meanwhile, the dispersing disc 4 is located below the baffle 2, with a diameter less than two-thirds of the inner diameter of the mixing cylinder 3, ensuring that the dispersed seeds fall directly into it. This layout not only improves the consistency of seed treatment but also ensures the stability and accuracy of subsequent steps.

[0037] Specifically, in the design of baffle 2, the spacing between each guide groove 6 can be adjusted according to actual application requirements. A spacing of 15 to 30 mm is generally recommended to avoid affecting seed flow and causing accumulation. Furthermore, the number of guide grooves 6 should be determined based on the area of ​​the seed inlet 1 and the expected processing volume to ensure a moderate seed flow rate within each guide groove 6. The cross-sectional shape of the guide groove 6 can be rectangular or arc-shaped, with rounded edges to reduce potential frictional damage to the seed surface. The effective combination of the guide grooves 6 and the dispersing disk 4 allows seeds entering from the top of baffle 2 to reach the target area at a controlled speed and under gentle conditions.

[0038] In one embodiment, a baffle 2 of the seed treatment device for virus-free potato cultivation is installed below the seed inlet 1, and the inclination angle of the baffle 2 is set between 15 and 30 degrees. This inclination angle is to optimize the seed sliding path and ensure that the seeds are evenly distributed on the baffle 2 when entering the device, avoiding the overlapping of seeds due to excessive stacking, which would affect the treatment effect.

[0039] Specifically, the width of baffle 2 is designed to be wider than that of seed inlet 1, so that the seeds can disperse and slide smoothly down the inclined surface of baffle 2, and be successfully transferred to the dispersion disc 4 below. This design allows the seeds to be more fully and evenly mixed and have a better chance of drug adhesion throughout the mixing process. Baffle 2, seed inlet 1, and mixing cylinder 3 form a continuous and smooth transfer path, ensuring that each seed can move along a predetermined trajectory, thereby improving the overall efficiency of the device. In addition, the position of baffle 2 and its precise placement relative to other components (such as the seed inlet 1 above and the dispersion disc 4 below) also ensure the safety and stability of the equipment operation.

[0040] In one embodiment, return to reference Figure 2The mixing cylinder 3 of the seed mixing device for virus-free potato cultivation disclosed in this application is equipped with a ring-shaped spray pipe 7 at its top. This spray pipe 7 is fixed to the top of the mixing cylinder 3 by a special mounting structure and connected to an external liquid supply system. Specifically, the interior of the spray pipe 7 is a circular flow channel to ensure unobstructed flow of the liquid. Several spray heads 8 are arrayed at the bottom of the spray pipe 7. These spray heads 8 are finely designed, with each spray head 8 containing multiple outlets of different spray diameters to accommodate different types and concentrations of liquid.

[0041] The design of the spray nozzles 8 is crucial to ensuring that the pesticide solution is evenly sprayed onto the seeds inside the mixing tank 3. For example, the layout and angle of each spray nozzle 8 are precisely calculated to cover the entire projected area of ​​the top of the mixing tank 3, thus ensuring that all seeds receive uniform pesticide contact. This evenly distributed spraying method effectively prevents the problem of localized over- or under-treatment of the pesticide solution, allowing each seed to be treated under the same conditions.

[0042] For example, high-quality corrosion-resistant materials can be used to make the spray pipe 7 and spray head 8 assembly, which can be firmly installed on the top of the mixing cylinder 3 by means of threaded connection. At the same time, the working pressure of the spray head 8 can be adjusted by the pressure control system to ensure that the liquid medicine flows out from each nozzle evenly at a predetermined speed and pattern, and finally achieve the ideal seed mixing effect.

[0043] In one embodiment, the surface of the dispersion disc 4 of a seed dressing device for virus-free potato planting according to this application is provided with a plurality of longitudinal grooves 9 (see...). Figure 4 These grooves facilitate further seed dispersion. In this seed mixing device, the dispersion disc 4 is installed below the baffle 2, located in the center of the mixing cylinder 3, ensuring that seeds sliding down from the baffle 2 are evenly distributed on the surface of the dispersion disc 4 and preventing them from concentrating when subsequently falling into the mixing cylinder 3. This arrangement allows the seeds to be evenly spread on the surface of the dispersion disc 4, preventing them from stacking or sticking together, thus enabling the pesticide solution to more fully contact and evenly cover each seed.

[0044] For example, to achieve effective seed dispersion, longitudinal grooves 9 are arranged radially at intervals along the dispersion disk 4, with a moderate depth to avoid affecting the strength and stability of the dispersion disk 4. After the seeds slide onto the dispersion disk 4, they will slide into the grooves under the influence of gravity and friction on the surface of the dispersion disk 4, thus being further dispersed under the guidance of the grooves. Specifically, the geometric design of these grooves ensures that each seed has an independent movement path on the dispersion disk 4, avoiding direct contact between seeds and ensuring maximum dispersion before entering the mixing cylinder 3, laying a good foundation for subsequent mixing steps.

[0045] In one embodiment, such as Figure 2 and Figure 3 As shown, the bottom of the outlet funnel 5 of the seed mixing device for virus-free potato planting in this application is equipped with a conveying cylinder 10. The conveying cylinder 10 is located in a key part of the entire device and can stably and evenly transport the seeds after mixing to the outside. The conveying cylinder 10 is a vertically placed closed tubular structure, and its top end is directly connected to the outlet funnel 5, ensuring that the seeds falling from the funnel can directly enter the internal space of the conveying cylinder 10.

[0046] Furthermore, a spiral conveying shaft 11 is provided inside the conveying cylinder 10. The spiral conveying shaft 11 is a slender shaft-shaped object with evenly distributed spiral blades wound around its outer circumference. These spiral blades, when rotating, propel and carry the seeds downwards from the conveying cylinder 10 through mechanical action. It is worth noting that the spiral conveying shaft 11 is not isolated but connected to a drive motor 12, thus obtaining the power source for rotation. The drive motor 12 is typically installed in a safe and stable position near the top or side of the conveying cylinder 10, and indirectly transmits power to the spiral conveying shaft 11 via gears or belts to ensure reliable power transmission. For example, in implementing the above structure, a geared motor with certain torque and low-speed characteristics can be selected as the drive power source to meet the needs of long-term operation in agricultural environments and ensure stable transmission performance. In addition, the spiral conveying mechanism, designed in conjunction with the entire system, can effectively prevent the instantaneous accumulation of seeds at the outlet, thereby ensuring output stability and quality.

[0047] In one embodiment, the width of the baffle 2 in the seed mixing device for virus-free potato cultivation is set to be 10% to 30% larger than the width of the seed inlet 1. Specifically, this slight increase in size helps prevent unnecessary accumulation of potato seeds in the initial stage of entering the device, ensuring that the seeds can be introduced and dispersed more quickly and evenly in the working area of ​​the next stage component. As the first structural element immediately below the seed inlet 1, the baffle 2 functions to initially divert the falling seeds. This design aims to minimize the obstruction of seeds at the narrow inlet of the device due to gravity and other factors. When the baffle 2 has a reasonable width exceeding that of the seed inlet above it, from a macroscopic perspective, it can effectively improve the smoothness and stability of the seed dispensing process, laying a good material foundation for the smooth progress of subsequent mixing steps.

[0048] For example, this width requirement can be achieved by adjusting the design of the connector between the fixing baffle 2 and the main body of the device. During installation, the overall coverage area of ​​the baffle 2 can be slightly larger than that of the seed inlet 1 by appropriately widening the fixing frame or selecting a prefabricated component of suitable width. In this way, whether seeds are added individually or in batches, the larger contact surface allows them to be immediately dispersed and smoothly slide along the baffle 2, which has a certain angle design, onto the dispersion disc 4 below for further processing. This process relies on reasonable construction and assembly to achieve the technical characteristics set for the target.

[0049] In one embodiment, such as Figure 2 As shown, the mixing mechanism of the seed treatment device for virus-free potato cultivation according to this application is located in the middle of the mixing cylinder 3. Through a reasonable component layout, the seed treatment process is further optimized. The mixing shaft 13 is vertically installed in the center of the mixing cylinder 3 and extends along the height of the mixing cylinder. Connected to the mixing shaft 13 are multiple mixing blades 14, which are distributed around the mixing shaft 13 at a specific angle to ensure that the seeds are fully agitated during the mixing process. The top of the mixing shaft 13 is firmly connected to a mixing motor 15 mounted above it. Through the coordinated work of this motor, mixing shaft 13, and mixing blades 14, seed stacking can be significantly reduced, and the coverage and uniformity of the pesticide solution can be improved, so that each seed can effectively contact the pesticide solution.

[0050] Specifically, for example, during equipment assembly, the stirring blades 14 are first fixed to the stirring shaft 13 at predetermined intervals to ensure that the blades have a suitable tilt angle. Then, the stirring shaft 13 is placed at the designated center position of the mixing cylinder 3, and its vertical centering and stable rotation are ensured through appropriate positioning measures. After that, the stirring motor 15 is securely mounted on the top cover of the mixing cylinder 3, and the motor output shaft is tightly connected to the stirring shaft 13. This ensures that the motor can accurately drive the stirring shaft 13 and its blades to operate together, achieving a uniform stirring effect.

[0051] In actual operation, when this device is in use, potato seeds to be treated are introduced into the device through seed inlet 1. The seeds are dispersed by baffle 2 to prevent them from piling up upon entering the device. Baffle 2 is inclined, allowing the seeds to slide down the slope onto the dispersion plate 4 below. Dispersion plate 4 ensures that the seeds are evenly distributed, further preventing seed accumulation, and guides the seeds into the mixing drum 3. At this time, the stirring mechanism is activated inside the mixing drum 3 to thoroughly mix the solution and seeds. The dispersed seeds have more uniform contact with the solution, improving the adhesion of the solution. After mixing is complete, the treated seeds fall into the outlet funnel 5 at the bottom. Due to the reasonable diameter design of the outlet funnel 5, the seeds are gradually discharged without piling up, ensuring a continuous and smooth operation. Finally, the treated seeds are successfully output from the outlet funnel 5 and ready for subsequent planting processes.

[0052] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
