Description

Technical Field

[0001] This utility model relates to the field of seed cleaning technology, and specifically to a seed cleaning system. Background Technology

[0002] Before processing or storage, seeds need to be cleaned, disinfected, and degreased to remove surface dirt, bacteria, and other impurities. Traditional cleaning methods typically involve manual operation or simple mechanical devices. Due to uneven mixing during manual or mechanical processes, the washed seeds often exhibit insignificant and uneven coloring, resulting in low efficiency. Furthermore, the traditional circulating dry grinding method leads to incomplete and uneven coloring, fails to disinfect and sterilize, and results in significant breakage and loss. Therefore, traditional methods negatively impact seed quality and suffer from low efficiency, incomplete cleaning, and high seed breakage rates. Utility Model Content

[0003] To solve the above problems, this utility model provides a seed cleaning system, including: a circular track, a basket, a drive device for driving the basket to move along the circular track and enabling the basket to rise and fall, and a raw material silo, a chemical cleaning machine, a first draining platform, a clean water cleaning machine, and a second draining platform arranged sequentially from upstream to downstream of the process flow. A belt scale is installed below the raw material silo, and both the chemical cleaning machine and the clean water cleaning machine are equipped with air pump devices for generating bubbles.

[0004] Based on the above scheme, the driving device is provided with a fully open material gate at the bottom of the basket and a movable anti-overflow cover at the top of the basket.

[0005] Based on the above scheme, it also includes a drug solution and water treatment device, which includes a drug preparation tank, a drug storage tank, a drug filtration tank, a clean water tank, and a filtered water tank. The outlet of the drug preparation tank is connected to the inlet of the drug cleaning machine through a first pipeline. The drug storage tank is connected to the drug preparation tank and the drug filtration tank through a second pipeline and a third pipeline, respectively. The inlet of the drug filtration tank is connected to the outlet of the drug cleaning machine through a fourth pipeline. The clean water tank and the filtered water tank are connected to the inlet and outlet of the clean water cleaning machine through a fifth pipeline and a sixth pipeline, respectively.

[0006] Based on the above scheme, the air pump device includes a high-pressure air pump, a high-pressure main air pipe and high-pressure branch air pipes. There are multiple high-pressure branch air pipes, which are respectively connected to the high-pressure main air pipe and distributed at the bottom of the cleaning pool. Each high-pressure branch air pipe is provided with an air outlet.

[0007] Based on the above scheme, the diameter of the air outlet is designed to gradually change along the direction of the high-pressure bronchus, with a smaller diameter at the end closer to the high-pressure main air pipe and a larger diameter at the end farther away from the high-pressure main air pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] The system automates the transport of the baskets via a circular track and drive unit, completing the operation from material collection to cleaning. The high-pressure bubbles generated by the air pump drive the seeds to tumble and wash, ensuring that the seed surface is in full contact with the liquid or water, significantly shortening the cleaning time. The air outlet design on the high-pressure air pipe ensures uniform release of pressurized gas, ensuring consistent seed cleaning quality. The use of a liquid and water treatment device to treat and reuse the used liquid and water effectively saves resources. Attached Figure Description

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.

[0018] This utility model provides a seed cleaning system designed to improve the automation level of seed collection and cleaning, increase work efficiency, and ensure the effectiveness of seed cleaning. Figure 1 As shown, the system mainly includes:

[0019] Circular track: Supports the continuous cyclical movement of the suspended platform along the track;

[0020] A hanging basket, used to load seeds, capable of moving along a track and being raised and lowered;

[0021] A drive unit is used to drive the suspended platform along the track and to raise and lower the platform.

[0022] The raw material silo stores seeds to be processed, and a belt scale is installed below it for measuring and conveying materials;

[0023] The chemical cleaning machine uses sodium hypochlorite solution to disinfect and remove stains from seeds;

[0024] The first draining platform is used to initially drain the pesticide residue from the surface of the seeds;

[0025] A water washing machine removes residual pesticides and impurities from the surface of seeds using clean water.

[0026] The second draining platform further drains the moisture from the surface of the seeds;

[0027] The chemical solution and water treatment device is used to supply chemical solution and clean water to the chemical solution cleaning machine.

[0028] The entire system operation process is as follows:

[0029] The basket 3 moves to the raw material silo 1 under the action of the drive device 4, and the belt scale 2 transports the seeds from the raw material silo to the basket. The basket then enters the chemical cleaning machine 5, the first draining platform 6, the clean water cleaning machine 7, and the second draining platform 8 in sequence. In the chemical cleaning machine, the seeds are disinfected and destained by sodium hypochlorite solution. The seeds are initially drained of the chemical solution on the surface by the first draining platform. In the clean water cleaning machine, the residual chemical solution on the surface of the seeds is removed by clean water. The seeds are then initially drained of moisture by the second draining platform.

[0030] During the cleaning process, a large number of fine air bubbles generated by the air pump enter the cleaning tank through the sieve plate holes at the bottom of the basket, so that the seeds are suspended in the basket, ensuring thorough cleaning and protecting the seeds from damage to the greatest extent.

[0031] Specifically, the suspended basket moves along a circular track under the action of the drive device and can move up and down. When the basket reaches the appropriate position, the seeds in the raw material bin 1 are transported into the suspended basket 3 by the belt scale 2. It should be noted that there is a gap between the belt scale and the basket during feeding, and the two are set at an angle. The seeds have an upward acceleration, and the seeds are thrown into the basket by 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 with the belt scale. This ensures that the basket does not come into mechanical contact with other devices, thus avoiding additional friction or damage, and also avoids affecting the normal movement of the basket.

[0032] The circular track supports the continuous cyclical movement of the suspended platform along the track, and the circular track frame 21 provides support for the circular track, providing a stable running path for the suspended platform.

[0033] 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 buttons 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.

[0034] According to this application, devices such as pneumatic hoists, hydraulic lifts, linear motors, ball screw lifts, or chain conveyors can also be used to move and lift the suspended platform.

[0035] like Figure 2 As shown, the basket 3 is surrounded by sieve holes 31 around its perimeter and bottom door. 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 anti-overflow cover. The anti-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.

[0036] After the seed collection is completed, the basket 3 places the seeds into the chemical cleaning machine 5 and the water cleaning machine 7 in sequence for cleaning. The seeds are disinfected and descaled by the sodium hypochlorite solution in the chemical cleaning machine, and then the residual sodium hypochlorite solution on the surface of the seeds is washed away in the water cleaning machine.

[0037] like Figure 3 and Figure 4 As shown, both the liquid cleaning machine and the water cleaning machine are equipped with air pump devices for generating bubbles. The air pump device includes a high-pressure air pump 51, a high-pressure main air pipe 52, and high-pressure branch air pipes 53. 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 there are multiple high-pressure branch air pipes, each 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 air outlet. The air 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.

[0038] Specifically, the high-pressure air pump can be a high-pressure vortex air pump, a Roots blower, or a screw air compressor, etc.

[0039] Preferably, the diameter of the circular hole is designed to gradually change along the direction of the high-pressure branch pipe. The diameter of the outlet hole is small at the end closer to the high-pressure main pipe and large at the end farther away from the high-pressure main pipe. Since the gas pressure decreases with increasing distance, this design can ensure the uniform release of bubbles, thereby improving the uniformity of bubble distribution in the cleaning tank and the consistency of cleaning effect.

[0040] The chemical cleaning machine 5 also includes an overflow port 54 and a drain port 55. A sodium hypochlorite solution of appropriate concentration is injected into the chemical cleaning machine and kept at a certain height with the overflow port. During cleaning, excess liquid is discharged through the overflow port, maintaining the liquid level in the cleaning tank within a stable range. The contaminated solution that can no longer be used is discharged from the cleaning machine through the drain port.

[0041] During operation, 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. The seeds remain suspended in the basket, where a high-pressure air pump generates high-pressure bubbles 57. These bubbles collide with the seed surface as they rise, creating an impact force. This impact force effectively removes dirt, impurities, and microorganisms from the seed surface, ensuring thorough cleaning.

[0042] 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.

[0043] The seed cleaning system also includes a solution and water treatment device, such as... Figure 5 As shown, the drug solution and water treatment unit includes a dosing tank 10, a storage tank 11, a filtration tank 12, a clean water tank 13, and a filtered water tank 14. The outlet of the dosing tank is connected to the inlet 56 of the drug cleaning machine via a first pipeline. The storage tank is connected to the dosing tank and the filtration tank via second and third pipelines, respectively. The inlet of the filtration tank is connected to the outlet of the drug cleaning machine via a fourth pipeline. The clean water tank and the filtered water tank are connected to the inlet and outlet of the clean water cleaning machine via fifth and sixth pipelines, respectively. The dosing tank and the filtration tank provide the drug solution to the drug cleaning machine, and the clean water tank and the filtered water tank provide the clean water to the clean water cleaning machine. The dosing tank prepares the sodium hypochlorite solution and supplies it to the drug cleaning machine or stores it in the storage tank. The contaminated solution during the cleaning process is transported to the filtration tank for filtration. Once the filtered solution meets the required concentration, it is returned to the drug cleaning machine. The clean water tank stores clean water for the clean water cleaning machine. The contaminated water in the clean water cleaning machine is transported to the filter water tank, and the filtered clean water is returned to the clean water cleaning machine.

[0044] Furthermore, the waste sediment in the filter tank is discharged and treated in an environmentally friendly manner. The clean medicine is returned to the medicine cleaning machine for reuse according to the proportion control. The dirty water at the bottom of the filter water tank is discharged after meeting the standards. The settled water can be reused, which can realize the environmentally friendly treatment of waste, and at the same time realize the reuse of medicine and water, saving resources.

This narrative style is merely for clarity.
