Description

Technical Field

[0001] This invention belongs to the field of disinfection equipment technology, and more specifically, relates to a seed disinfection device for crop seed production. Background Technology

[0002] Seed disinfection is an important measure in agricultural production. It aims to kill or inhibit pathogens, viruses, insect eggs and other harmful organisms on or inside the seed through physical, chemical or biological methods, thereby reducing the occurrence of diseases, preventing pests after sowing, and improving seed germination rate and crop yield and quality. Common seed disinfection methods include chemical soaking, chemical seed dressing, and high-temperature disinfection.

[0003] Existing seed disinfection devices for crop seed production still have some shortcomings in practical use:

[0004] 1. Traditional seed disinfection devices for crop seed production usually use manual or simple mechanical stirring to mix seeds and chemicals, which can easily lead to uneven mixing of seeds and chemicals, reducing the disinfection effect;

[0005] 2. Traditional seed disinfection devices for crop seed production are mostly single-function and cannot achieve automatic seed feeding, uniform mixing, or precise seed dispensing. Furthermore, the disinfection process may suffer from problems such as chemical volatilization polluting the environment and poor device sealing leading to the entry of external impurities. Therefore, this paper studies and improves upon existing structures and shortcomings to provide a seed disinfection device for crop seed production, aiming to achieve greater practical value.

[0011] Furthermore, the infusion tube is connected to the infusion port of the metering pump, and a solenoid valve is installed on the infusion tube.

[0012] Furthermore, a feeding assembly is provided on the base plate. The feeding assembly includes a receiving box, a rotating shaft, and a second motor. The rotating shaft is rotatably installed at the bottom of the inner cavity of the receiving box, and a spiral blade is fixedly installed on the rotating shaft.

The baffle plate is movably inserted into the discharge port.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] I. This seed disinfection device for crop seed production uses a motor to drive the spiral blades to rotate, conveying seeds from the receiving box through the feed pipe, port one, and port two into the receiving component inside the rotating drum. At the same time, the rotation of the drum causes port two to align with port one in sequence, achieving uniform distribution of seeds into the four disinfection chambers and improving the consistency of disinfection effect. The feed component realizes automatic seed feeding, reducing manual operation and labor intensity. The spiral conveying channel formed by the spiral blades can stably and efficiently transport seeds to the designated position, ensuring the continuity and stability of the feeding process.

[0019] II. During the seed feeding process, the eccentric wheel of this seed disinfection device for crop seed production causes the connecting plate and baffle two to vibrate. This, combined with the inclined surface design on the upper surface of the connecting plate, effectively breaks up seed accumulation, allowing seeds to be quickly and evenly distributed within the disinfection chamber. This helps the seeds to fully contact the disinfectant, improving the uniformity and effectiveness of disinfection. The rotating drum causes the seeds to tumble continuously within the disinfection chamber, thoroughly mixing with the disinfectant. After the disinfectant spraying is complete, the motor two is restarted in reverse, driving the eccentric wheel to reverse as well, causing the connecting plate and baffle two to vibrate again. This further promotes the mixing of seeds and disinfectant, ensuring that the seed surface is evenly exposed to the disinfectant, comprehensively improving the disinfection effect and guaranteeing the quality of seed disinfection.

[0020] Third, the sealing plate at one of the openings, together with components such as the infusion tube, effectively seals the disinfection chamber, preventing the evaporation of the medicine and the entry of external impurities, maintaining the stability of the disinfection environment, ensuring that the disinfection process is not disturbed by external factors, and ensuring the reliability of the disinfection effect. The support rings at both ends of the rotating drum are embedded in the annular grooves on the inner walls of both sides of the round shell, providing stable support and limiting the rotating drum, and ensuring the stability of the rotating drum during rotation.

[0021] IV. The seed disinfection device for crop seed production is driven by a motor to rotate the drum, which allows the discharge port 2 to be precisely aligned with the discharge port 1. The electric telescopic rod controls the raising and lowering of the baffle plate, controlling the timing of the discharge and achieving orderly discharge. This ensures that the seeds can be discharged from the disinfection device in sequence and stably, facilitating subsequent collection and processing. The vibration generated by the reverse rotation of the eccentric wheel and the design of the upper surface of the connecting plate tilting towards the discharge port accelerate the discharge of seeds from the disinfection chamber under the dual action of gravity and vibration, improving the discharge efficiency, reducing seed residue in the device, and ensuring the efficient completion of the disinfection process.

[0022] Fifth, the two baffles are located between the two vertical plates, and the through rod moves through the through hole on the vertical plate. This not only prevents seeds from entering the non-working area, but also limits the movement of the connecting plate, ensuring the stable operation of the housing component and improving the reliability and stability of the device.

[0042] Example:

[0043] As attached Figure 1 To be continued Figure 14 As shown:

[0044] This invention provides a seed disinfection device for crop seed production, comprising a base plate 1 and a circular shell 2 fixedly mounted on the base plate 1. A rotating cylinder 3 is rotatably mounted inside the circular shell 2. A connecting shaft 31 is fixedly mounted at the middle of both ends of the rotating cylinder 3. Four openings 35 are equidistantly spaced on the outer surface of the rotating cylinder 3. A cross plate 32 is fixedly mounted inside the rotating cylinder 3. A receiving cavity 36 communicating with the openings 35 is formed between the cross plate 32 and the inner wall of the rotating cylinder 3. Four sets of vertical plates 33 are equidistantly mounted on the cross plate 32. An opening 21 adapted to the openings 35 is opened on the upper surface of the circular shell 2. A sealing plate 22 is provided at the opening 21 and is fixedly mounted on the circular shell 2 to seal the opening 21. An infusion tube 5 is fixedly installed inside the tube. Several nozzles 51 are fixedly installed at equal intervals at the bottom of the infusion tube 5. The nozzles 51 spray the agent simultaneously, which can completely cover the seed surface. The sealing plate 22 plays a sealing role, sealing the disinfection chamber to prevent the agent from evaporating and external impurities from entering, thus ensuring the stability of the disinfection environment. A metering pump 52 is installed on the round shell 2, which can accurately control the amount of agent discharged. Each receiving chamber 36 is equipped with a receiving component 4. The receiving component 4 includes a connecting plate 41 and two baffles 42. The two baffles 42 are fixedly installed on both sides of the upper end of the connecting plate 41, and the baffles 42 play a blocking role. The two baffles 42 and the connecting plate 41 form a disinfection chamber to prevent the seeds from falling onto the cross plate 32.

[0045] Each receiving cavity 36 is equipped with a jacking assembly, which includes a rotating shaft 9. Several eccentric wheels 91 are fixedly installed on each rotating shaft 9. Each rotating shaft 9 is rotatably installed in the receiving cavity 36. The rotation of the eccentric wheels 91 drives the connecting plate 41 to vibrate, so as to avoid seed accumulation during the feeding process and make the seeds discharge more smoothly during the unloading process.

[0046] A discharge port 2 37 is provided on one side surface of the rotating drum 3. Mounting base 1 11 and mounting base 2 13 are fixedly installed on both sides of the upper end of the bottom plate 1, respectively. Two connecting shafts 31 are rotatably connected to mounting base 11 and mounting base 2 13, respectively. A protective plate 23 is fixedly installed on one end of the round shell 2 near mounting base 11. The surface of the protective plate 23 is provided with a discharge port 24 that matches the discharge port 2 37. The setting of the protective plate 23 effectively prevents seeds from entering the interior of the rotating drum 3 from the port of the round shell 2 during the feeding process.

[0047] The upper surface of the connecting plate 41 is designed with an incline. Two through rods 43 are fixedly installed at opposite ends of the two baffles 42. Several springs 44 are fixedly installed on each through rod 43. There are two vertical plates 33 in each group. Each vertical plate 33 is fixedly connected to the inner wall of the rotating drum 3. The two baffles 42 are located between the two vertical plates 33. The surface of each baffle 42 is in contact with the surface of each vertical plate 33. Each vertical plate 33 has a through hole 34 on its surface. Each through rod 43 moves through the through hole 34. Each through rod 43 is fixedly connected to the inner wall of the rotating drum 3 by springs 44. The through rod 43 moves through the through hole 34 on the vertical plate 33, which not only prevents seeds from entering the receiving cavity 36, but also limits the movement of the connecting plate 41, ensuring the stable operation of the receiving assembly 4.

[0048] Both sides of the inner wall of the circular shell 2 are provided with annular grooves 25. Each opening 35 is provided with a contact plate 38. Each contact plate 38 is fixedly installed on the rotating cylinder 3. Both sides of the rotating cylinder 3 are fixedly sleeved with support rings 39. Each contact plate 38 is fixedly connected to the inner wall of the support ring 39. Each support ring 39 is rotatably installed in the annular groove 25. The surface of each contact plate 38 is in contact with the inner wall of the circular shell 2 to prevent the seeds from being thrown out of the sterilization chamber into the circular shell 2 during the rotation of the rotating cylinder 3.

[0049] The infusion tube 5 is connected to the infusion port of the metering pump 52. A solenoid valve is installed on the infusion tube 5 to control the opening and closing of the infusion tube 5.

[0050] A feeding assembly 7 is provided on the base plate 1. The feeding assembly 7 includes a receiving box 71, a rotating shaft 72, and a second motor 74. The rotating shaft 72 is rotatably installed at the bottom of the inner cavity of the receiving box 71. A spiral blade 73 is fixedly installed on the rotating shaft 72. The second motor 74 is fixedly installed on the outer wall of the receiving box 71. The output shaft of the second motor 74 is fixedly connected to the rotating shaft 72. A first synchronous wheel 75 is fixedly installed on the rotating shaft 72. An extension tube 76 is fixedly installed on the receiving box 71. The rotating shaft 72 and the spiral blade 73 are rotatably installed inside the extension tube 76. A feeding pipe 77 is fixedly installed at the bottom end of the extension tube 76. When the rotating shaft 72 and the spiral blade 73 rotate, the seeds in the receiving box 71 are discharged from the feeding pipe 77 into the disinfection chamber. The feeding pipe 77 passes through the sealing plate 22. Two support plates 16 are fixedly installed between the receiving box 71 and the base plate 1. The feeding assembly 7 realizes the uniform distribution of the seeds in the receiving box 71 into the disinfection chamber.

[0051] Gear 8 is mounted on mounting base 2 13. A connecting ring 81 is fixedly mounted on gear 8. A limiting ring 82 is fixedly sleeved on the connecting ring 81. A connecting shaft 31, which is rotatably connected to mounting base 2 13, movably passes through gear 8 and connecting ring 81. Mounting base 2 13 has a mounting groove 14 on its surface. An annular groove 15 is formed on the inner wall of mounting groove 14. The limiting ring 82 is located in the annular groove 15 and is used to support and limit gear 8 to ensure stable rotation of gear 8.

[0052] A drive shaft 83 is rotatably mounted on the upper end of mounting base 2 13. Gear 2 84 and synchronous pulley 2 85 are fixedly mounted on both ends of the drive shaft 83, respectively. Gear 2 84 meshes with gear 1 8. Synchronous belt 78 is sleeved on synchronous pulley 2 85 and synchronous pulley 1 75. Gear 3 92 is fixedly mounted on each rotating shaft 9. Each gear 3 92 meshes with gear 1 8 and is used for transmission between rotating shaft 72, drive shaft 83 and rotating shaft 9.

[0053] The mounting base 11 houses a motor 1 for driving the rotating drum 3. An encoder is mounted on the output shaft of the motor 1 to precisely control the degree of rotation of the rotating drum 3, facilitating accurate loading and unloading. The connecting shaft 31, which is rotatably connected to the mounting base 11, is fixedly connected to the output shaft of the motor 1. The top surface of the mounting base 11 is designed with a slope. Baffles 12 are fixedly mounted on both sides of the upper end of the mounting base 11. A support base 6 is fixedly mounted on the upper end of the sealing plate 22. An electric telescopic rod 61 is fixedly mounted on the support base 6. A baffle plate 62 is fixedly connected to the telescopic rod of the electric telescopic rod 61. The baffle plate 62 is movably inserted into the discharge port 24. The operation of the electric telescopic rod 61 controls the vertical movement of the baffle plate 62, realizing the opening and closing of the discharge stage.

[0054] The working principle of this embodiment:

[0055] Step 1: When using the equipment, the operator first puts the crop seeds to be disinfected into the container 71, and then starts the motor 2 74. Its output shaft drives the rotating shaft 72 to rotate, and the spiral blades 73 fixed on the rotating shaft 72 rotate accordingly. The spiral blades 73 form a spiral conveying channel in the container 71 and the extension tube 76, pushing the seeds out from the feed tube 77 and conveying them through the first port 21 and the second port 35 to the container assembly 4 in the container cavity 36. At the same time, the motor 1 is started, and the output shaft of the motor 1 drives the connecting shaft 31 to rotate, which in turn drives the rotating drum 3 to rotate. As the rotating drum 3 rotates, the second port 35 on its outer side aligns with the first port 21 on the upper side of the round shell 2 in sequence, so that the seeds in the container 71 are evenly distributed into the four container assemblies 4. The container assembly 4 in each container cavity 36 plays its role, and the seeds fall into the disinfection cavity formed by the connecting plate 41 and the two baffles 42.

[0056] Step 2: When the rotating shaft 72 rotates under the drive of the second motor 74, the first synchronous pulley 75 fixed on it rotates accordingly. Through the transmission of the synchronous belt 78, the second synchronous pulley 85 is driven to rotate, which in turn causes the drive shaft 83 to rotate. The second gear 84 at both ends of the drive shaft 83 and the second synchronous pulley 85 rotate synchronously. The second gear 84 meshes with the first gear 8, driving the first gear 8 to rotate. The first gear 8 then meshes with the third gear 92 on each rotating shaft 9, causing the rotating shaft 9 to start rotating. The eccentric wheel 91 fixed on the rotating shaft 9 also rotates accordingly. During the rotation process, the irregular shape of the eccentric wheel 91 will apply a periodic force to the connecting plate 41. Under the reset action of the spring 44, the connecting plate 41 rotates... The connecting plate 41 drives the two baffles 42 to move back and forth and generate vibration. During the feeding process of seeds entering the disinfection chamber from the feed pipe 77, the inclined surface design of the upper surface of the connecting plate 41 and the vibration form an efficient synergy. When the seeds accumulate below the feed pipe 77, the vibration breaks the accumulation state of the seeds due to gravity, and enhances the sliding and rolling ability of the seeds on the inclined surface. Under the dual action of vibration and inclined surface, the seeds can be quickly and evenly distributed in the disinfection chamber. After the seeds are evenly distributed, the metering pump 52 is started. The agent is delivered to the infusion pipe 5 under the action of the metering pump 52, and the seeds in each disinfection chamber are sprayed with agent for disinfection through multiple nozzles 51 at the bottom of the infusion pipe 5.

[0057] Step 3: After the spraying of the agent is completed, the motor continues to drive the connecting shaft 31, which drives the rotating drum 3 to rotate continuously. During the rotation, the contact plate 38 on the outside of the rotating drum 3 is always in close contact with the inner wall of the round shell 2. At the same time, the opening 21 is located on the upper surface of the round shell 2, which effectively prevents the seeds from leaking into the round shell 2 during the rotation. The rotation of the rotating drum 3 causes the seeds to roll continuously in the disinfection chamber and mix thoroughly with the agent, ensuring that the surface of the seeds can be evenly contacted with the disinfectant, thus improving the disinfection effect.

[0058] Step 4: After the seeds in each disinfection chamber have been mixed for a period of time, start motor 74 again to reverse it. At this time, all the seeds in the container 71 have been distributed to each disinfection chamber. The reverse rotation of shaft 72 will not cause any additional impact. The reverse rotation of shaft 72 is transmitted through synchronous belt 78, synchronous pulley 75, synchronous pulley 85, drive shaft 83, gear 84, gear 8, and gear 92, which causes shaft 9 and eccentric wheel 91 to also reverse. The reverse rotation of eccentric wheel 91 drives connecting plate 41 and two baffles 42 to move back and forth and vibrate again, further promoting the mixing of seeds and agents and ensuring that the disinfection effect reaches the best.

[0059] Step 5: When the feeding process begins, start the motor 1 in the mounting base 11 to drive the rotating drum 3 to rotate, so that the discharge port 2 37 at the rotating drum 3 is precisely aligned with the discharge port 24 on the protective plate 23 of the round shell 2. Then start the electric telescopic rod 61, which drives the baffle plate 62 to move upward and disengage from the discharge port 24, thus removing the obstruction to the discharge channel. At this time, the connecting plate 41 and the two baffle plates 42 continue to move back and forth under the vibration generated by the reverse rotation of the eccentric wheel 91. In addition, the upper surface of the connecting plate 41 is designed to be inclined towards the discharge port 24. Under the dual action of gravity and vibration, the seeds in the disinfection chamber are smoothly discharged from the discharge port 2 37 and the discharge port 24. After the seeds in one disinfection chamber are discharged, the rotating drum 3 continues to rotate to discharge the seeds in the other disinfection chambers in turn, thus completing the entire disinfection process.

[0060] Step 6: Two baffles 42 are located between two vertical plates 33, and their surfaces are in close contact with the surfaces of the vertical plates 33. At the same time, the through rod 43 moves through the through hole 34 on the vertical plate 33, which not only prevents seeds from entering the receiving cavity 36, but also limits the movement of the connecting plate 41, ensuring the stable operation of the receiving component 4. The sealing plate 22 set at the opening 21, together with the infusion tube 5 and other components, effectively seals the disinfection cavity, preventing the evaporation of the agent and the entry of external impurities, and ensuring the stability of the disinfection environment.

[0061] Step 7: The support rings 39 fixedly installed at both ends of the rotating drum 3 are respectively embedded in the annular grooves 25 on both sides of the inner wall of the circular shell 2, providing stable support and limiting for the rotating drum 3, and ensuring the stable rotation of the rotating drum 3.
