Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed treatment technology, specifically to a disinfection and descaling system for seeds. Background Technology
[0002] Seed washing and drying are important pretreatment steps in agricultural production. Their purpose is to remove dirt, pathogens, and other impurities from the seed surface, while ensuring the seeds reach an ideal dry state before storage or sowing. However, traditional seed washing and drying systems have many shortcomings, which limit their application in modern agriculture.
[0003] First, low cleaning efficiency is a common problem. Traditional methods rely heavily on manual operation or simple mechanical devices, making continuous production impossible, resulting in long cleaning times and inconsistent results. Second, uneven cleaning quality is a significant issue; traditional cleaning methods struggle to guarantee consistent seed cleaning. This inefficient and ineffective approach is particularly unacceptable in large-scale industrial production. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a disinfection and descaling system for seeds, comprising: a circular track, a hanging basket, a drive device for driving the hanging basket along the track and enabling the hanging basket to rise and fall, and a raw material silo, a chemical cleaning machine, a first draining platform, a clean water cleaning machine, a second draining platform, and a bed dryer arranged sequentially from upstream to downstream of the process flow. A belt scale is installed below the raw material silo, and the material in the raw material silo is quantitatively transported to the hanging basket by the belt scale. There are several bed dryers. Both the chemical cleaning machine and the clean water cleaning machine are equipped with air pump devices for generating bubbles.
[0005] Based on the above scheme, the bottom of the suspended basket is provided with a fully open material gate, and the top of the suspended basket is provided with a movable anti-overflow cover. The anti-overflow cover can be opened and closed and is connected to the top of the suspended basket or can be detachably connected to the top of the suspended basket.
[0006] Based on the above scheme, the basket is surrounded by sieve plate holes on its sides and bottom door, and the diameter of the sieve plate holes is smaller than the minimum size of the seed particles.
[0007] Based on the above scheme, the air pump device includes a high-pressure air pump, a high-pressure main air pipe and a high-pressure branch air pipe.

[0008] Based on the above scheme, the bed dryer includes a water pumping device, the bed plate of the drying bed of the bed dryer is a perforated plate, and the air extraction port of the water pumping device is located below the drying bed.
[0009] Based on the above scheme, the bed dryer also includes a process regulating valve for adjusting the airflow. Under the action of the water pumping device, the moisture of the seeds flows down into the channel through the sieve plate and is discharged, and the flow rate is controlled by the process regulating valve.
[0010] Based on the above scheme, a spreading mechanism and a fixing part are provided on the side of the hanging basket away from the direction of movement. The spreading mechanism includes a rotating shaft, a swing rod and a spreading part. The swing rod is rotatably connected to the hanging basket through the rotating shaft.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0022] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] To improve the automation level and cleaning and drying efficiency of seed treatment, this utility model proposes a disinfection and descaling system for seeds, mainly comprising:
[0024] Circular track: Supports the continuous cyclical movement of the suspended platform along the track;
[0025] A hanging basket, used to load seeds, capable of moving along a track and being raised and lowered;
[0026] A drive unit is used to drive the suspended platform along the track and to raise and lower the platform.
[0027] The raw material silo stores seeds to be processed, and a belt scale is installed below it for measuring and conveying materials;
[0028] The chemical cleaning machine uses sodium hypochlorite solution to disinfect and remove stains from seeds;
[0029] The first draining platform is used to initially drain the pesticide residue from the surface of the seeds;
[0030] A water washing machine removes residual pesticides and impurities from the surface of seeds using clean water.
[0031] The second draining platform further drains the moisture from the surface of the seeds;
[0032] A bed dryer is used to dry seeds.
[0033] Both the liquid washing machine and the water washing machine are equipped with air pumps to generate bubbles to assist in the washing process; the bed dryer accelerates the drainage process of the seeds through a water pumping device, significantly shortening the drying time.
[0034] like Figure 1 and Figure 2As shown, the system includes a circular track 20, a suspended basket 3, a drive device 4 for driving the suspended basket to move along the track and raising and lowering the suspended basket, and a raw material silo 1, a chemical cleaning machine 5, a first draining platform 6, a clean water cleaning machine 7, a second draining platform 8, and a bed dryer 9 arranged sequentially from upstream to downstream of the process flow. A belt scale 2 is installed below the raw material silo 1, and there are several bed dryers. Both the chemical cleaning machine and the clean water cleaning machine are equipped with air pump devices for generating bubbles.
[0035] The entire system operation process is as follows:
[0036] Material handling stage: The basket 3 moves along the circular track 20 under the action of the drive device 4, and can move up and down. When the basket moves to a suitable position under the action of the drive device, the belt scale 2 transports the seeds in the raw material bin 1 into the basket 3. Specifically, during feeding, there is a gap between the belt scale and the basket, and the two are set at an angle. The seeds have an upward acceleration, and the seeds are thrown into the basket under the action of the belt scale. The basket moves downward under the action of the drive device, moving the seeds on the belt scale into the basket without contacting the basket and the belt scale. This ensures that the basket does not make mechanical contact with other devices, thus avoiding additional friction or damage, and also avoids affecting the normal movement of the basket.
[0037] The circular track can support the suspended basket to move continuously along the track, and the system also includes a circular track frame 21, which supports the circular track and provides a stable running path for the suspended basket.
[0038] like Figure 3 As shown, to prevent material leakage, the basket 3 is surrounded by sieve holes 31 on all sides and at the bottom. The diameter of the sieve holes is smaller than the minimum size of the seed particles, while ensuring unobstructed passage of the cleaning solution and water during the cleaning process. The bottom of the basket is equipped with a fully open material gate 32, which reduces the impact force during material discharge, acts as a buffer, and avoids damage to the dryer body. The fully open material gate adopts an embedded structure, and its tight fit design ensures that there is no residue during material discharge. At the same time, the top of the basket is equipped with a movable overflow cover. The overflow cover can be opened and closed or detachably connected to the top of the basket, which is used to enable loading operations from the top and effectively prevent material overflow.
[0039] Preferably, the drive device 4 is an electric hoist. According to this application, the belt scale adds 300-500 kg of material to each basket. The basket needs to move along the track and rise and fall to complete the washing, draining, and drying processes. The electric hoist uses a motor to drive a wire rope or chain to achieve vertical lifting of the basket, and combines a remote control or button to achieve precise horizontal movement control. This design can meet the needs of the basket switching between various processing modules. Furthermore, the electric hoist has a high load capacity (typically hundreds of kg to several tons), perfectly suited for scenarios where baskets are loaded with 300-500 kg of seeds. In addition, the electric hoist has a simple structure and is easy to maintain, reducing the cost and complexity of long-term use, and enabling stable equipment operation while maintaining reliable performance under high-frequency use.
[0040] According to this application, the drive device can also use a pneumatic hoist, hydraulic lift, linear motor, ball screw lift or chain conveyor to realize the movement and lifting of the basket.
[0041] With the help of belt scales, drive devices and circular tracks, seeds are automatically loaded and transported, realizing automated operation, simplifying manual intervention and making the whole process more efficient and precise.
[0042] Cleaning stage:
[0043] like Figure 5 and Figure 6 As shown, after the material is collected, the seeds are placed into the chemical cleaning machine 5 and the clean water cleaning machine 7 in sequence through the basket. The seeds are disinfected and destained by the sodium hypochlorite solution in the chemical cleaning machine, and then the sodium hypochlorite solution and impurities on the surface of the seeds are washed away in the clean water cleaning machine.
[0044] The air pump device includes a high-pressure air pump 51, a high-pressure main air pipe 52, and high-pressure branch air pipes. Multiple high-pressure branch air pipes are connected to the high-pressure main air pipe and evenly distributed at the bottom of the cleaning tank. The high-pressure air pump delivers gas to the cleaning tank through the high-pressure main air pipe and the high-pressure branch air pipes. The high-pressure air pump provides sufficient pressure and flow to meet the large-capacity cleaning needs of 300-500 kg in the basket, ensuring cleaning efficiency and quality. The high-pressure air pump delivers gas to the cleaning tank through the high-pressure main air pipe and the high-pressure branch air pipes. The high-pressure main air pipe extends to the bottom of the cleaning machine, and multiple high-pressure branch air pipes are connected to the high-pressure main air pipe and evenly distributed at the bottom of the cleaning machine. Each high-pressure branch air pipe has an outlet. The outlets are evenly distributed at the bottom of the cleaning tank, allowing the pressurized gas to form a large number of fine bubbles that cover all parts of the tank, thus ensuring thorough cleaning of the seeds.
[0045] Specifically, the high-pressure air pump can be a high-pressure vortex air pump, a Roots blower, or a screw air compressor, etc.
[0046] During seed cleaning, the seeds are sequentially immersed in a chemical cleaning machine and a clean water cleaning machine via a suspended basket. The perforated sieve plate on the basket ensures unobstructed passage of pressurized gas and chemical solution, keeping the seeds suspended and guaranteeing thorough cleaning. Specifically, the pressure from the air bubbles, carried by the chemical solution through the sieve plate, causes the solution to agitate and wash the seeds. The pressure is uniform throughout the basket, ensuring a consistent and gentle washing experience, minimizing seed damage, and guaranteeing consistent decolorization, disinfection, and stain removal quality after washing.
[0047] The first and second draining stations are located after the chemical cleaning machine and the clean water cleaning machine, respectively, to remove excess water from the surface after cleaning. This not only reduces chemical residue and ensures cleaner seeds, but also reduces the burden on subsequent processes and improves overall cleaning efficiency.
[0048] Drying stage:
[0049] After washing and draining, the basket is moved above the bed dryer, and the fully open material gate at the bottom of the basket is opened to completely discharge the material onto the drying bed 93. It should be noted that because the material is piled up on the drying bed in the form of small hills after unloading, it is not conducive to uniform water discharge when the water pumping device is pumping air and water. Therefore, it is advisable to spread the material on the drying bed. If it is spread manually, it is time-consuming, labor-intensive and has safety hazards. Therefore, a spreading mechanism 34 is set up to spread the material using the walking of the basket itself, which is efficient and has fewer hidden dangers.
[0050] like Figure 3 and Figure 4 As shown, the side of the hanging basket opposite to the direction of movement is provided with a spreading mechanism 34 and a fixing part 33. The spreading mechanism includes a rotating shaft 341, a swing rod 342 and a spreading part 343. The swing rod is rotatably connected to the hanging basket through the rotating shaft. The fixing part is fixedly connected to the hanging basket. The swing rod and the fixing part are detachably connected. After unloading, the spreading part spreads the seeds on the drying bed by moving the hanging basket.
[0051] During operation, the swing arm of the spreading mechanism is disassembled from the fixed part, allowing the spreading mechanism to move. The swing arm is then rotated downwards along the rotating shaft until it can no longer rotate; at this point, the spreading mechanism forms an acute angle with the vertical direction. As the basket moves along the track, the bottom end of the swing arm maintains a certain height with the drying bed, and this height can be adjusted according to the basket's position. Through the movement of the basket, the seeds are evenly spread onto the drying bed by the spreading arm.
[0052] The bed dryer includes a water pumping device 92 and a flow regulating valve 91 for adjusting the airflow. The water pumping device can remove moisture leaking from the seeds on the bed, and under the action of the dryer, it can effectively improve the drying speed and reduce the seed drying time. The bed plate of the drying bed of the bed dryer is a perforated plate. The air intake of the water pumping device is located below the drying bed. Under the action of the water pumping device, the moisture of the seeds falls and is discharged through the perforated plate, and the airflow is adjusted by the flow regulating valve.
[0053] Specifically, the water pumping device can be a water pumping fan, a vacuum pump, or a gravity drain, etc.
[0054] The diameter of the sieve holes on the sieve plate is smaller than the minimum size of the seeds to prevent seed leakage. At the same time, the hot air generated by the dryer is evenly distributed to the entire bed through the sieve plate, making the temperature more uniform, promoting air convection circulation, and further improving drying efficiency.
[0055] like Figure 6 As shown, in actual use, each drying bed is equipped with a flow regulating valve 91. After the drying bed is filled with seeds, the valve is opened, and the water drained by the water extraction fan is discharged outside through the fan. When no more water is discharged from the fan, the fan is stopped, the valve is closed, and the dryer is started. By using the water extraction fan, the dryer efficiency can be increased by 30%, saving 1 / 2 of the drying time and effectively increasing the overall production capacity.
[0056] During the system's cleaning, draining, and drying processes, cleaning and draining require relatively little time, while drying takes a long time. Therefore, the cleaning and draining steps often have to wait for the drying steps, resulting in low overall operating efficiency. While setting up multiple bed dryers can improve efficiency to some extent, it significantly increases the system's construction and operating costs. However, by installing a water pumping device and actively extracting air, the moisture between the seeds on the drying bed is quickly drained and discharged by the pumping device. This not only greatly saves on system construction costs but also improves system operating efficiency, increasing dryer efficiency by 30%, saving half of the drying time, and effectively increasing overall production capacity.
