Description

Technical Field

[0001] This utility model relates to the field of wheat breeding technology, and in particular to a drug soaking and stirring device for wheat breeding. Background Technology

[0002] In wheat breeding, standardized drug soaking and stirring treatments are required to achieve goals such as seed disinfection, initiation (improving germination rate), or introduction of specific active substances (such as stress-inducing agents). Wheat breeding drug soaking and stirring devices are intelligent agricultural equipment specifically designed for this stage. Their core function is to ensure uniform contact between seeds and drugs by precisely controlling drug concentration, temperature, soaking time, and stirring intensity, while avoiding mechanical damage. This provides standardized seed samples for subsequent breeding experiments (such as variety selection and stress resistance identification).

[0003] In existing technologies, to prevent wheat seeds from settling at the bottom of the tank, a geared motor is typically used to rotate the stirring blades, turning the wheat seeds over to avoid uneven contact between the seeds and the soaking liquid due to prolonged static storage. However, the thickness of the wheat seed coat is typically 50-150 micrometers, and the rigid structure of the stirring blades and the localized eddies generated during rotation cause high-frequency impacts between the seeds and the blades and tank walls. Furthermore, the thin seed coat and elliptical shape of wheat seeds make their rolling trajectory unstable, further exacerbating the collisions. This damages the seed's structure and negatively impacts subsequent seedling cultivation and development.

[0004] Therefore, this application provides a drug soaking and stirring device for wheat breeding to meet the needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a drug soaking and stirring device for wheat breeding to solve the problem that the existing stirring blades easily cause wheat seeds to collide with external structures, resulting in damage to wheat seeds and affecting subsequent seedling cultivation.

[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0007] A drug soaking and stirring device for wheat breeding, comprising: Main body of the device; The soaking chamber, located inside the main body of the device, is cylindrical and is configured to store the soaking solution. A drum, disposed within the soaking chamber, is used to rotate and cause the wheat placed inside it to move rhythmically and come into full contact with the soaking liquid. The drum includes: The main body has a side wall with several main connecting holes for connecting the main body side wall and the soaking chamber, so as to facilitate the exchange of soaking solution between the main body side wall and the soaking chamber; The cover is detachably connected to one end of the side wall of the main body; A transmission cover is fixedly connected to the side wall of the main body at the end away from the disassembly cover. A driving component is fixedly connected to the end of the transmission cover away from the disassembly cover, which is used to change the working state of the roller through the driving component.

[0008] Preferably, the soaking chamber is set at an angle of 1-3°.

[0009] Preferably, the main body sidewall comprises: The threaded grooves are formed on the inner wall of the main body and are evenly distributed in a spiral shape along the inner wall. They are arc-shaped grooves used to disperse and accommodate seeds, reduce seed stacking and compression, and prevent seeds from colliding disorderly in the drum. An elastic sheet, fitted to the arc surface of the threaded groove, provides cushioning when the moving wheat comes into contact with itself.

[0010] Preferably, the connection between the threaded groove and the inner wall of the main body sidewall is rounded.

[0011] Preferably, the removable cover includes: Several first connecting holes are used to connect the main body sidewall and the soaking chamber to enhance the exchange efficiency of the soaking liquid between the main body sidewall and the soaking chamber; Several bolts are threadedly connected to the disassembly cover and the main body side wall to fix the disassembly cover and the main body side wall together, so that the disassembly cover and the main body side wall rotate synchronously.

[0012] Preferably, the transmission cover includes: Several second connecting holes are provided to connect the main body sidewall and the soaking chamber, thereby enhancing the exchange efficiency of the soaking liquid between the main body sidewall and the soaking chamber.

[0013] Preferably, the driving component is disposed inside the main body of the device and is fixedly connected to the inner wall of the main body of the device.

[0014] Preferably, the main body of the device includes: A liquid inlet is located at the top of the main body of the device and communicates with the soaking chamber, for connecting to external equipment to inject the soaking liquid into the soaking chamber; An isolation plate is fixedly connected inside the main body of the device to isolate the soaking chamber from the driving component; A sealing cap is rotatably connected to the front side wall of the device body, and is used to change the communication state between the soaking chamber and the outside of the device body by rotating itself; A drainage channel is located at the bottom of the soaking chamber and communicates with the outside, used to drain the soaking liquid from the soaking chamber.

[0015] Preferably, it further includes: A drain control valve is installed in the drain channel. The input end is connected to the end of the drain channel near the soaking chamber, and the output end is connected to the end of the drain channel away from the soaking chamber. It is used to control the working state of the drain channel.

[0016] Preferably, it further includes: The controller is electrically connected to the drive unit and the drain control valve, and is used to control the working state of the drive unit and the drain control valve.

[0017] This invention provides a drug soaking and stirring device for wheat breeding. Compared with the prior art, it has the following advantages: 1. The perforated roller and internal trough design confine the seed's movement within a controllable space, preventing random collisions caused by fluid eddies. Simultaneously, the roller's rotation causes the seeds to rise and slide orderly along the trough, rather than randomly tumbling under fluid impact. This reduces the probability of collisions and avoids the problem of high-frequency impacts between seeds and the blades and trough walls caused by the rigid structure of the stirring blades and localized eddies. This minimizes damage to the wheat seed coat and ensures the seed's subsequent seedling and planting development.

[0018] 2. The rolling mechanism continuously tumbles the seeds in the soaking solution, and the perforated design on the roller ensures exchange of the solution between the inside and outside, allowing the seeds to be evenly contacted with the solution. Compared to existing stirring methods using agitator blades, this method more comprehensively covers the seed's active space, reduces dead zones, and improves the uniformity of soaking.

[0028] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0030] Reference Figures 1-8 A wheat breeding drug soaking and stirring device, comprising: The main body 10 of the device must have sufficient structural strength to support core components such as the soaking chamber 20, the roller, and the drive component 60. The material can be 304 stainless steel, which is not only corrosion resistant and can resist the erosion that may be caused by the drug components in the soaking solution, thus extending the service life of the equipment, but also has good welding and processing performance, making it easy to install and fix the various components.

[0031] The soaking chamber 20, located inside the main body 10 of the device, is cylindrical and is used to store the soaking solution. The inner wall of the soaking chamber 20 can be polished to reduce the amount of soaking solution remaining on the chamber wall, making subsequent cleaning easier. On the other hand, it reduces the resistance to liquid flow and avoids uneven flow rate of the soaking solution in some areas due to rough chamber walls, which would affect the soaking effect.

[0032] A drum, positioned within the soaking chamber 20, is used to rotate and cause the wheat placed inside to move rhythmically and come into full contact with the soaking liquid. The drum includes: The main body sidewall 30 has several main connecting holes 31 for connecting the main body sidewall 30 and the soaking chamber 20, facilitating the exchange of soaking solution between the main body sidewall 30 and the soaking chamber 20. The diameter of the main connecting holes 31 can be set to 2-3mm, which can ensure that the soaking solution flows quickly between the inside of the drum and the soaking chamber 20 to achieve efficient exchange, while preventing wheat seeds from leaking out of the holes. The main connecting holes 31 are evenly distributed on the sidewall of the main body sidewall 30, such as being arranged at intervals of 10-15mm along the circumferential direction and the axial direction, so as to ensure that the soaking solution exchange efficiency is consistent at different positions when the drum rotates.

[0033] The detachable cover 40 is detachably connected to one end of the main body side wall 30. Bolts 42 facilitate the opening and closing of the drum, allowing wheat to be soaked to be transported into the drum or soaked wheat to be removed. A rubber sealing ring can be installed at the connection between the detachable cover 40 and the main body side wall 30 to further enhance sealing performance and prevent leakage of soaking solution from affecting the operation of the device.

[0034] The transmission cover 50 is fixedly connected to the end of the main body side wall 30 away from the disassembly cover 40. The end of the transmission cover 50 away from the disassembly cover 40 is fixedly connected to a driving component 60, which is used to change the working state of the roller through the driving component 60.

[0035] The entire drum can be made of food-grade 304 stainless steel. 304 stainless steel contains chromium and nickel, which can form a stable oxide film that can resist the corrosion of acidic and alkaline drug components in the soaking solution, preventing the material from rusting and contaminating the seeds or affecting the purity of the soaking solution. At the same time, the tensile strength (≥520MPa) and yield strength (≥205MPa) of 304 stainless steel can meet the mechanical requirements of each component, preventing deformation and breakage when the drum rotates.

[0036] The soaking chamber 20 is set at an angle of 1-3°. This angled design utilizes gravity to create a slow flow of the soaking solution within the chamber. This promotes circulation of the soaking solution, improves the uniformity of drug concentration, and prevents excessively high or low local drug concentrations from affecting seed treatment. Furthermore, during drainage, the angled structure ensures more thorough drainage from the drainage channel 14, reducing residue at the bottom of the chamber. Maintaining the angle within 1-3° achieves these benefits without causing uneven stress on the drum during rotation due to an excessively large angle, which could affect equipment stability. It also prevents seeds from excessively shifting to one side within the drum, thus avoiding stacking.

[0037] The main body sidewall 30 includes: The threaded grooves 32, formed on the inner wall of the main body side wall 30 and evenly distributed in a spiral shape along the inner wall, are arc-shaped grooves used to disperse and accommodate seeds, reduce seed stacking and compression, and prevent seeds from colliding disorderly in the drum. The spirally distributed threaded grooves 32 can drive the seeds to move slowly along the spiral trajectory when the drum rotates, so that the seeds can be turned over in an orderly manner in the drum. The threaded grooves 32 can accommodate a certain number of seeds, effectively disperse the seeds, and prevent a large number of seeds from being stacked together and crushed to each other, causing damage. The arc-shaped groove design can better fit the elliptical shape of the seeds, reducing the rigid collision between the seeds and the groove wall.

[0038] The elastic sheet 33, fitted to the curved surface of the threaded groove 32, provides cushioning when moving wheat comes into contact with it. The elastic sheet 33 is preferably made of silicone, which has good elasticity and wear resistance, effectively absorbing the impact force generated by the collision between the seed and the groove wall, minimizing damage to the seed coat. Furthermore, silicone is chemically stable and will not react with the drugs in the soaking solution, ensuring the safety of seed treatment. The thickness of the elastic sheet 33 is controlled at 1-2mm; too thick and it reduces the capacity of the threaded groove 32, too thin and it will not provide adequate cushioning. Food-grade adhesive can be used to tightly bond the elastic sheet 33 to the curved surface of the threaded groove 32, ensuring it will not detach during long-term use.

[0039] The connection between the threaded groove 32 and the inner wall of the main body side wall 30 is rounded to eliminate sharp edges at the connection and prevent the seeds from colliding with the edges and causing damage during movement.

[0040] The removable cover 40 includes: Several first auxiliary connecting holes 41 are used to connect the main body sidewall 30 and the soaking chamber 20, thereby enhancing the efficiency of soaking liquid exchange between the main body sidewall 30 and the soaking chamber 20. The first auxiliary connecting holes 41 complement the main connecting holes 31, further increasing the flow channel of the soaking liquid. Especially in the area at both ends of the drum, it can effectively improve the soaking liquid exchange speed in this area and avoid uneven seed soaking due to untimely soaking liquid renewal at both ends of the drum.

[0041] Several bolts 42 are threadedly connected to the disassembly cover 40 and the main body side wall 30 to fix the disassembly cover 40 and the main body side wall 30 together, so that the disassembly cover 40 and the main body side wall 30 rotate synchronously. The number of bolts 42 is usually set to 4-6, evenly distributed along the circumference of the disassembly cover 40, so that the disassembly cover 40 is subjected to uniform force and avoids deformation due to uneven force during rotation. At the connection between the bolts 42 and the disassembly cover 40, flat washers and spring washers can be set. Flat washers can increase the contact area and reduce the pressure of the bolts 42 on the disassembly cover 40, while spring washers can play an anti-loosening role and prevent the bolts 42 from loosening due to the rotation of the roller.

[0042] The transmission cover 50 includes: Several second connecting holes 51 are used to connect the main body sidewall 30 and the soaking chamber 20, thereby enhancing the exchange efficiency of soaking liquid between the main body sidewall 30 and the soaking chamber 20. The function of the second connecting holes 51 is similar to that of the first connecting holes 41, which can further optimize the flow effect of soaking liquid inside the drum.

[0043] The drive component 60 is disposed inside the main body 10 of the device and is fixedly connected to the inner wall of the main body 10. The drive component 60 is preferably a geared motor, which can provide stable torque and appropriate speed. The speed can be controlled between 5-10 r / min, which can drive the drum to rotate slowly, so that the seeds can fully contact the soaking solution, while avoiding excessive speed that would cause the seeds to collide with the drum wall.

[0044] The main body 10 of the device includes: The liquid inlet 11 is located at the top of the main body 10 of the device and communicates with the soaking chamber 20. It is used to connect with external equipment to inject soaking liquid into the soaking chamber 20. A filter screen can be fixedly installed in the liquid inlet 11 to filter impurities in the soaking liquid and prevent impurities from entering the soaking chamber 20 and affecting the quality of seed treatment.

[0045] The isolation plate 12 is fixedly connected inside the main body 10 of the device and is used to isolate the soaking chamber 20 from the drive component 60. The material of the isolation plate 12 is preferably stainless steel, and can be the same material as the main body 10 of the device.

[0046] The sealing cover 13 is rotatably connected to the front side wall of the device body 10. It is used to change the communication state between the soaking chamber 20 and the outside of the device body 10 by rotating itself. The middle part of the sealing cover 13 can be made of transparent material so that the staff can directly observe the inside of the soaking chamber 20 through the sealing cover 13.

[0047] The drain channel 14 is located at the bottom of the soaking chamber 20 and is connected to the outside. It is used to drain the soaking solution in the soaking chamber 20. The drain channel 14 is located at the bottom of the soaking chamber 20 to ensure that the soaking solution can be completely drained during the draining process and to reduce residue. The end of the drain channel 14 away from the soaking chamber 20 can be connected to a hose so that the drained soaking solution can be output to a designated location.

[0048] Also includes: The drain control valve 80 is installed in the drain channel 14. The input end is connected to the end of the drain channel 14 near the soaking chamber 20, and the output end is connected to the end of the drain channel 14 away from the soaking chamber 20. It is used to control the working state of the drain channel 14. The drain control valve 80 can be a solenoid valve, specifically the Rexroth 4WE6 series solenoid directional valve. It has strong flow capacity, can meet different flow requirements, has good sealing performance, can effectively prevent soaking liquid leakage, is suitable for a variety of working media, and meets the requirements of the equipment for processing drug soaking liquid.

[0049] Also includes: The controller 70, electrically connected to the drive unit 60 and the drain control valve 80, is used to control the operating status of the drive unit 60 and the drain control valve 80. The controller 70 can be a PLC controller, which offers flexible programming, high reliability, strong anti-interference capabilities, and adaptability to complex working conditions. Specifically, a Siemens S7-1200 series PLC can be selected. This series has a rich instruction set, which can meet the equipment's precise control programming requirements for parameters such as the speed of the drive unit 60 and the opening time of the drain control valve 80. Furthermore, its powerful communication functions facilitate connection to touch screens and other devices for human-machine interaction, and it also possesses strong anti-interference performance.

[0050] Working Process and Principle: When using this wheat breeding drug soaking and stirring device, the operator first opens the sealing cover 13, then removes the disassembly cover 40 using the bolts 42 on the disassembly cover 40. The wheat seeds to be treated are placed inside the main body side wall 30 of the drum. The disassembly cover 40 is then re-secured to the main body side wall 30 using the bolts 42, ensuring synchronous rotation and a good seal at the connection. The sealing cover 13 is then closed. Next, the controller 70 controls the drain control valve 80 to prevent the soaking solution from being discharged from the drain channel 14. An appropriate amount of soaking solution is then injected into the soaking chamber 20 through the inlet 11, which connects to the soaking chamber 20 at the top of the device body 10. The soaking solution enters the drum through the main connecting hole 31, the first auxiliary connecting hole 41, and the second auxiliary connecting hole 51, contacting the wheat seeds. The controller 70 activates the drive unit 60, which drives the transmission cover 50, thereby rotating the entire drum. As the drum rotates, the spirally distributed arc-shaped grooves 32 on the inner wall of the main body sidewall 30 drive the seeds to move slowly along the spiral trajectory, dispersing and accommodating them, reducing stacking, compression, and disorderly collisions. Simultaneously, the 1-2mm thick silicone elastic sheet 33, fitted to the arc surface of the grooves 32, provides cushioning for the moving wheat seeds, preventing seed coat damage. Due to the inclined setting of the soaking chamber 20, the soaking solution flows slowly under gravity, promoting circulation, ensuring uniform drug concentration, and facilitating subsequent drainage. After the soaking and stirring reaches the preset time, the controller 70 controls the drive unit 60 to stop working, the drum stops rotating, and then controls the drainage control valve 80 installed in the drainage channel 14 at the bottom of the soaking chamber 20 to open, allowing the soaking solution in the soaking chamber 20 and the drum to drain through the drainage channel 14. After drainage is complete, the controller 70 controls the drainage control valve 80 to close, and the operator reopens the sealing cover 13 and the disassembly cover 40 to remove the treated wheat seeds, completing one round of wheat seed drug soaking and stirring treatment.
