Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed coating technology, and specifically relates to a seed coating mixing device for agricultural products. BACKGROUND

[0002] The seed coating mixing device is a device for wrapping a specific material on the surface of seeds to improve the sowing performance and growth efficiency of the seeds. China has been researching seed coating technology since the late 1970s, and has developed coating agents and coating machines for various seeds such as vegetables, cotton, and pasture. These devices have achieved good results through field mechanized sowing tests. The coating agent usually contains fungicides and insecticides, which can prevent and control seed diseases and pests in the soil after coating the seeds, protecting the seeds from soil-borne pathogens and pests.

[0003] When coating the seeds, the coating agent is stored in the hopper, and the coating agent is pumped into the coating box by the pump to form a spray that falls on the seeds and stirs and turns the seeds, making the seed coating uniform. However, the hopper does not have a liquid level monitoring function, and when the coating agent is used up, it cannot be replenished in time, which may cause the pump to dry out and be damaged, and the seed coating may not be uniform. After coating the seeds, the coating agent on the surface of the seeds cannot be dried when the seeds are discharged, and the seeds need to be collected and transferred to a drying device for drying, which is time-consuming and labor-intensive. SUMMARY

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0028] like Figures 1-8 As shown, an agricultural product seed coating and mixing device includes: a coating box 1, a feed hopper 101 installed on one side of the top of the coating box 1, a material box 102 set on one side of the outer end of the coating box 1, a feeding assembly set on the outer end of the material box 102, the feeding assembly including: a liquid level sensor 2, a control box 201, a storage box 3, a feeding pump 301, a feeding pipe 302 and a feeding pipe b303, and a drying assembly set on the bottom of the coating box 1, the drying assembly including: a discharge platform 4, a stainless steel conveyor belt 401, a servo motor 402, a fixing frame 403 and a baking lamp 404.

[0029] The material tank 102 is equipped with a material pump 103 at the top, a material extraction pipe 104 is installed between the material pump 103 and the material tank 102, and a material feeding pipe a105 is installed between the material pump 103 and the coating box 1. The top of the coating box 1 is equipped with multiple nozzles 106 connected to the material feeding pipe a105. The coating box 1 is rotatably connected to a rotating shaft 107 through a sealed bearing. A roller 108 is installed on the rotating shaft 107. Multiple stirring plates 109 are installed on the roller 108. A stirring motor 110 is installed at the outer end of the coating box 1 and is driven by the rotating shaft 107.

[0030] When coating seeds, seeds are added into the coating box 1 from the feed hopper 101, so that the seeds come into contact with the stirring plate 109 inside the coating box 1. At this time, the feed pump 103 is started, and the feed pump 103 generates negative pressure suction in the extraction pipe 104, which draws out the coating agent inside the feed box 102 and discharges it into the feeding pipe a105 through the feed pump 103. From the feeding pipe a105, it is discharged to the nozzle 106 to form a spray and spray it onto the seeds. At the same time, the stirring motor 110 is started, and the stirring motor 110 drives the rotating shaft 107 and the drum 108 to rotate. The drum 108 drives multiple stirring plates 109 to rotate and tumble and stir the seeds, ensuring that the coating agent is evenly sprayed on the seeds, thereby coating the seeds evenly.

[0031] The material tank 102 has a liquid level sensor 2 installed at its bottom. A control box 201 is installed on the outside of the material tank 102. A storage tank 3 is located on the outside of the material tank 102, and a feeding pump 301 is installed on the top of the storage tank 3. A feeding pipe 302 is installed between the feeding pump 301 and the storage tank 3, and a feeding pipe b303 is installed between the feeding pump 301 and the material tank 102. When the material tank 102 is in use, a feeding pipe is installed on its side, through which the coating agent can be added to the material tank 102 for storage. When the coating agent is extracted for use, the liquid level sensor 2 can monitor the liquid level of the coating agent inside the material tank 102 in real time. The liquid level sensor 2 and the feeding pump 301 are respectively connected to the control box 201. The control box 201 is connected by wires. When the liquid level is lower than the liquid level sensor 2, the liquid level sensor 2 sends the monitored liquid level information to the control box 201 via an electrical signal. After receiving and processing the information, the control box 201 starts the feeding pump 301. The feeding pump 301 generates a negative pressure suction in the feeding pipe 302, which draws out the coating agent in the storage tank 3 and discharges it into the feeding pipe b303 through the feeding pump 301. From the feeding pipe b303, it is discharged into the material box 102, which supplies the material box 102 in a timely manner without the need for manual addition, saving feeding time and avoiding damage to the feeding pump 103 due to dry burning. It can also supply the seeds for timely coating spraying, prevent the supply from being interrupted, and ensure uniform seed coating.

[0032] When feeding material into the material hopper 102, an observation window is provided on the outside of the material hopper 102. The coating agent added into the material hopper 102 can be seen through the observation window. When it is almost full, the operator can turn off the feeding pump 301 by controlling the control box 201 to avoid the coating agent in the material hopper 102 from overflowing and being wasted.

[0033] The liquid level sensor 2 consists of a capacitance measurement chip, a control chip, an operational amplifier unit, and an RS232 unit. The models of the capacitance measurement chip, control chip, and operational amplifier unit can be PCAP01AD / QFN32, PIC16F18346, and LM2904. Its working principle is as follows: The liquid level sensor 2 is a common sensor for measuring liquid level. It converts the height of the liquid level into an electrical signal for output. Generally, the specific gravity of the magnetic float is less than 0.5, allowing it to float on the liquid surface and move up and down along the measuring conduit. The conduit contains a measuring element, which, under the action of an external magnet, converts the measured liquid level signal into a resistance signal proportional to the change in liquid level. The electronic unit then converts this into a 4-20mA or other e-commerce standard signal output. The liquid level sensor 2 is a mature and conventional technology in this field, and this solution does not improve the circuitry or program of the liquid level sensor 2. The circuitry and signal connection between the liquid level sensor 2 and the control box 201 are also common and conventional technologies; therefore, their circuitry and signal connection relationships will not be elaborated upon.

[0034] The coating box 1 has a discharge port 5 at the bottom, and a movable opening 501 at the outer end of the discharge port 5. A baffle 502 is installed inside the discharge port 5, and the baffle 502 is tightly fitted to the cross-section of the discharge port 5. An electric push rod 503 connected to the baffle 502 is installed inside the movable opening 501. After the seeds are coated, the electric push rod 503 is activated to pull the baffle 502 from the discharge port 5 into the movable opening 501, opening the discharge port 5. This allows the seeds inside the coating box 1 to be discharged onto the stainless steel conveyor belt 401 inside the discharge platform 4, facilitating the conveying and drying of the discharged seeds.

[0035] The coating box 1 has a discharge platform 4 at its bottom. Inside the discharge platform 4, a stainless steel conveyor belt 401 is connected to the rotating roller. A servo motor 402 is installed at the outer end of the discharge platform 4, and a fixed frame 403 is installed at the top of the discharge platform 4. Multiple baking lamps 404 are installed inside the fixed frame 403. After the coated seeds are discharged onto the stainless steel conveyor belt 401, the servo motor 402 is started to drive the rotating roller to rotate the stainless steel conveyor belt 401, which in turn transports the seeds toward the discharge hopper 8 and the receiving box 9. During the transport process, the baking lamps 404 are activated. The baking lamps 404 generate high-temperature heat near the stainless steel conveyor belt 401. As the seeds pass by, they are heated and baked, which makes the coating agent on the seeds dry quickly. The drying process helps the coating layer to solidify and adhere quickly, ensuring that the seed coating layer has good stability and durability. The seeds are dried during discharge and collection, eliminating the need to transfer the collected seeds to drying equipment, thus saving time and labor and improving the efficiency of seed coating.

[0036] The discharge platform 4 has an installation block 6 installed on one side of its top, and a scraper 601 installed at the bottom of the installation block 6. There is a gap between the scraper 601 and the stainless steel conveyor belt 401. When the coated seeds are discharged onto the stainless steel conveyor belt 401, they will first come into contact with the scraper 601. Because there is a gap between the scraper 601 and the stainless steel conveyor belt 401, the scraper 601 can scrape the seeds on the stainless steel conveyor belt 401 flat, preventing the seeds from piling up together and ensuring that the seeds can be heated evenly when passing through the baking lamp 404, so that the moist coating agent on the surface of the seeds dries quickly.

[0037] Two rollers 7 are provided on one side of the top of the stainless steel conveyor belt 401. The outer ends of the two rollers 7 are equipped with rotating shafts 701 that are rotatably connected to the discharge platform 4. After the coating agent on the seeds dries, it passes through the two rollers 7. There is a gap between the two rollers 7 and the stainless steel conveyor belt 401. The rollers 7 roll and crush the seeds conveyed on the stainless steel conveyor belt 401, which can crush and loosen the clumps of seeds.

[0038] The discharge platform 4 is equipped with a discharge hopper 8 at its outer end. The bottom of the discharge hopper 8 is equipped with a receiving box 9. After being crushed and loosened, the seeds are conveyed from the stainless steel conveyor belt 401 and fall into the discharge hopper 8. The discharge hopper 8 is set at an inclination so that it can slide into the receiving box 9 for collection. The staff can collect and place the coated and dried seeds.

[0039] Working principle:

[0040] When coating seeds, seeds are added into the coating box 1 from the feed hopper 101, so that the seeds come into contact with the stirring plate 109 inside the coating box 1. At this time, the feed pump 103 is started, and the feed pump 103 generates negative pressure suction in the extraction pipe 104, which draws out the coating agent inside the feed box 102 and discharges it into the feeding pipe a105 through the feed pump 103. From the feeding pipe a105, it is discharged to the nozzle 106 to form a spray and spray it onto the seeds. At the same time, the stirring motor 110 is started, and the stirring motor 110 drives the rotating shaft 107 and the drum 108 to rotate. The drum 108 drives multiple stirring plates 109 to rotate and tumble and stir the seeds, ensuring that the coating agent is evenly sprayed on the seeds, thereby coating the seeds evenly.

[0041] When in use, the material tank 102 has a feeding pipe installed on its side. The coating agent can be added to the material tank 102 through the feeding pipe for storage and later use. When the coating agent is extracted for use, the liquid level sensor 2 can monitor the liquid level of the coating agent inside the material tank 102 in real time. The liquid level sensor 2 and the feeding pump 301 are respectively connected to the control box 201 via wires. When the liquid level is lower than the liquid level sensor 2, the liquid level sensor 2 sends the monitored liquid level information to the control box 201 via an electrical signal. After receiving and processing the information, the feed pump 301 is started. The feed pump 301 generates a negative pressure suction in the feed pipe 302, which draws out the coating agent in the storage tank 3 and discharges it into the feed pipe b303 through the feed pump 301. The agent is then discharged into the material tank 102 from the feed pipe b303, which provides timely material supply to the material tank 102 without the need for manual addition, saving feeding time and avoiding damage to the feed pump 103 due to dry burning. It can also provide timely material supply and spray coating for the seeds, prevent interruption of the supply, and ensure uniform seed coating.

[0042] After the coated seeds are discharged onto the stainless steel conveyor belt 401, the servo motor 402 is started to drive the rotating rollers, which in turn drive the stainless steel conveyor belt 401 to rotate, transporting the seeds towards the discharge hopper 8 and the collection box 9. During the transport process, the baking lamp 404 is activated. The baking lamp 404 generates high temperature heat near the stainless steel conveyor belt 401, heating and baking the seeds as they pass by, so that the coating agent on the seeds dries quickly. The drying process helps the coating layer to solidify and adhere quickly, ensuring that the seed coating layer has good stability and durability. The seeds are dried during discharge and collection, eliminating the need to transfer the collected seeds to drying equipment, thus saving time and labor and improving the efficiency of seed coating. The seeds are then transported from the stainless steel conveyor belt 401 and fall into the discharge hopper 8. The discharge hopper 8 is set at an incline, allowing the seeds to slide into the collection box 9 for collection. Workers can then collect and place the coated and dried seeds.
