Description

Technical Field

[0001] This invention relates to the field of seed dressing equipment technology, and in particular to a seed dressing device and method for purple clover phosphate fertilizer. Background Technology

[0002] As an important green manure crop, milkvetch plays a significant role in improving soil fertility, reducing chemical fertilizer use, and promoting rice yield. Phosphate fertilizer seed coating technology is a crucial step in milkvetch cultivation. By mixing seeds with phosphate fertilizer, it provides seedlings with essential phosphorus nutrition in the early stages of sowing, promoting root development and nitrogen fixation, thereby increasing germination rate and stress resistance. Traditional phosphate fertilizer seed coating relies heavily on manual operation, resulting in low efficiency, poor uniformity, and difficulty in meeting the needs of large-scale planting. Furthermore, milkvetch seeds are often coated with a waxy or dense seed coat; untreated seeds have a smooth surface, making it easy for phosphate fertilizer particles to fall off, thus reducing fertilizer utilization efficiency after coating. Existing seed coating devices lack a wiping function, requiring seeds to be pre-treated with other equipment, adding inconvenience to the seed coating process.

[0017] A method for seed dressing with milkvetch phosphate fertilizer, characterized by comprising:

[0018] Step 1: Place the milkvetch seeds into the seed box;

[0019] Step 2: Start the first and second motors. The seeds of milkvetch enter the shell. Driven by the first motor, the friction body rotates. Driven by the second motor, the shell rotates. The seeds will be rubbed between the shell and the friction body, making the seed surface rough.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-5 This invention provides a seed dressing device for milkvetch phosphate fertilizer, comprising:

[0033] An outer protective box 1 is provided, and a seed box 2 is fixedly connected to the outer protective box 1.

[0034] The seed wiping assembly includes a housing 3, inside which a friction body 4 is disposed. Both the housing 3 and the friction body 4 are rotatably disposed within an outer protective box 1. The friction body 4 is rotatably disposed within the housing 3, and a gap is provided between the friction body 4 and the housing 3. The outer surface of the friction body 4 and the inner surface of the housing 3 are both rough surfaces. The upper end of the housing 3 is connected to the seed box 2. Several first motors 5 and several second motors 6 are disposed inside the housing 3. The first motors 5 are drivenly connected to the friction body 4, and the second motors 6 are drivenly connected to the housing 3. A connecting funnel 7 is connected to the lower part of the housing 3, and a spraying mechanism is connected to the connecting funnel 7. The spraying mechanism is located inside the outer protective box 1.

[0035] The mixing assembly includes a mixing tank 8, which is connected to a spraying mechanism via a feeding mechanism 9. The feeding mechanism 9 extends out of the outer protective box 1. A fertilizer discharge mechanism is provided on the mixing tank 8, an agitation mechanism is provided inside the mixing tank 8, a discharge mechanism is provided on the mixing tank 8, and a collection box 10 is placed below the discharge mechanism.

[0036] In this device, the seed box 2 is used to put in the seeds of milkvetch. There is a gap between the outer shell 3 and the friction body 4. Under the action of its own gravity, the milkvetch seeds in the seed box 2 flow into the outer shell 3. The first motor 5 drives the friction body 4 to rotate, and the second motor 6 drives the outer shell 3 to rotate. The rotation directions of the friction body 4 and the outer shell 3 are opposite to each other. In addition, the outer surface of the friction body 4 is rough, and the inner surface of the outer shell 3 is rough. This can improve the efficiency of rubbing the seeds and make the surface of the milkvetch seeds rougher more quickly. After the milkvetch seeds are roughened, it is easier for them to adhere and bond. The seeds fall from the outer shell 3 into the connecting funnel 7, and then from the connecting funnel 7 into the spraying mechanism. The spraying mechanism is used to spray out the adhesive. After the adhesive is sprayed on the seed surface, it is beneficial for the fertilizer to adhere to the seed surface. After the adhesive is sprayed, the seeds enter the mixing tank 8 through the feeding mechanism. The fertilizer discharge mechanism releases fertilizer into the mixing tank 8. Under the action of the stirring mechanism, the milkvetch seeds and fertilizer come into full contact, so that more fertilizer adheres to the surface of the milkvetch seeds. After the seeds are coated, they are discharged into the collection box 10 through the discharge mechanism.

[0037] The scheme is further optimized. The outer shell 3 includes a neck shell 11 and an expansion shell 12. The neck shell 11 contracts inward and the expansion shell 12 expands outward. The neck shell 11 and the expansion shell 12 are fixedly connected. The upper end of the neck shell 11 is rotatably connected to a top cover 13. The top cover 13 is connected to the seed box 2 through a first connecting pipe 14. The bottom of the expansion shell 12 is provided with a first discharge port, which is connected to a connecting funnel 7. The expansion shell 12 is rotatably connected inside the outer protective box 1. The neck shell 11 is connected to the second motor 6 for transmission.

[0038] The inwardly contracting neck shell 11 approaches the friction body 4, allowing more clover seeds to be rubbed as they pass through the narrow section. The expansion shell 12 can hold more seeds. The shape of the neck shell 11 and the expansion shell 12 increases the residence time of the seeds in the outer shell 3. The top cover 13 is used to cover the outer shell 3. The first discharge port is used to discharge the clover seeds, which will fall into the connecting funnel 7.

[0039] The scheme is further optimized as follows: a first protective shell 15 is fixedly connected to the neck shell 11; a first gear ring 16 is fixedly connected to the outside of the first protective shell 15; a first fixed plate 17 and a second fixed plate 18 are fixedly connected inside the outer protective box 1; a second motor 6 is fixedly connected to the first fixed plate 17; a first gear 19 is fixedly connected to the output end of the second motor 6; the first gear 19 meshes with the first gear ring 16; a second protective shell 20 is fixedly connected to the outside of the expansion shell 12; the second protective shell 20 is rotatably connected to the second fixed plate 18 through a first bearing; a first base plate 21 is fixedly connected to the bottom surface of the upper cover 13; a second base plate 22 is fixedly connected to the neck shell 11; the first base plate 21 and the second base plate 22 are rotatably connected to each other through a second bearing; two protective rings 23 are fixedly connected to the second base plate 22, and the two protective rings 23 are located on both sides of the second bearing.

[0040] The expansion shell 12 is rotatably connected to the outer protective box 1 by the rotational connection between the second protective shell 20 and the second fixed plate 18. The second motor 6 drives the first gear 19 to rotate, and the first gear drives the first gear ring 16 to rotate, so that the second motor 6 can drive the neck shell 11 and the expansion shell 12 to rotate. The upper cover 13 is fixedly connected to the first connecting pipe 14. When the neck shell 11 rotates, the upper cover 13 does not rotate. The protective ring 23 is mainly used to protect the second bearing and prevent seeds from entering the second bearing.

[0041] The design is further optimized so that the friction body 4 includes a round rod 24 and a ball 25. The round rod 24 and the ball 25 are fixedly connected. The round rod 24 extends into the neck shell 11, and the ball 25 is located in the expansion shell 12. The round rod 24 passes through the upper cover 13. A third fixing plate 26 is fixedly connected inside the outer protective box 1. A first positioning tube 27 is fixedly connected to the third fixing plate 26. The round rod 24 is located inside the first positioning tube 27. The round rod 24 and the first positioning tube 27 are rotatably connected through a third bearing. A second gear 53 is fixedly connected to the round rod 24. A third gear 28 is fixedly connected to the first motor 5. The second gear 53 meshes with the third gear 28.

[0042] The round rod 24 is mainly located in the neck shell 11, and the sphere 25 is located inside the expansion shell 12. When the seed of milkvetch enters between the round rod 24 and the neck shell 11, it will be rubbed for the first time. As the seed continues to slide downward, the milkvetch seed will be rubbed for the second time between the expansion shell 12 and the sphere 25. This can make the surface of the milkvetch seed rougher. The outer surfaces of the round rod 24 and the sphere 25 are rough, and the inner surfaces of the neck shell 11 and the expansion shell 12 are rough. This is all designed to quickly roughen the surface of the seed. The first motor 5 drives the third gear 28 to rotate, and the third gear 28 drives the second gear 53 and the round rod 24 to rotate, thereby making the round rod 24 and the sphere 25 rotate.

[0043] The scheme is further optimized by fixing several second connecting pipes 29 to the connecting funnel 7 and fixing a third connecting pipe 30 to the first discharge port. The third connecting pipe 30 and the second connecting pipe 29 are rotatably connected through a fourth bearing. Several connecting rods 31 are fixedly connected inside the second connecting pipe 29. Second positioning pipes 32 are fixedly connected to the several connecting rods 31. A support column 33 is fixedly connected to the ball 25. The support column 33 is located inside the second positioning pipe 32. The support column 33 and the second positioning pipe 32 are rotatably connected through a fifth bearing.

[0044] The third connecting tube 30 is used to connect with the second connecting tube 29, so that the seeds can enter the connecting funnel 7 from the expansion shell 12. The support column 33 is used to support the ball 25. The support column 33 is rotatably connected in the second positioning tube 32. When the round rod 24 and the ball 25 rotate, it is more stable. The connecting rod 31 does not affect the falling of the seeds.

[0045] The design is further optimized. The spraying mechanism includes a spray box 34 and a solution tank 35. The upper end of the spray box 34 is connected to the connecting funnel 7. A guide cone 36 is fixedly connected inside the spray box 34. Several annular pipes 37 are fixedly connected inside the spray box 34. Several atomizing nozzles 38 are installed on the annular pipes 37. The atomizing nozzles 38 face the guide cone 36. The annular pipes 37 are connected to branch pipes 39. Several branch pipes 39 are connected to conveying pipes 40. A pressure pump 41 is located inside the solution tank 35. The liquid outlet of the pressure pump 41 is connected to the conveying pipe 40. Several second discharge ports 42 are opened on the spray box 34. The second discharge ports 42 are connected to the feeding mechanism 9.

[0046] The solution tank 35 contains adhesive, and the guide cone 36 in the spray tank 34 facilitates the scattering of seeds in all directions, allowing the seeds to approach the atomizing nozzle 38 during the scattering process. The pressure pump 41 pumps the adhesive solution to the atomizing nozzle 38, and the adhesive is sprayed out through the atomizing nozzle 38 onto the seed surface. The seed surface becomes rough after friction, making it easier for the adhesive to adhere. After the seeds are sprayed with adhesive in the spray tank 34, they fall into the feeding mechanism 9 through the second discharge port 42, and are then transported by the feeding mechanism 9.

[0047] The fertilizer discharge mechanism further optimizes the design by including a fertilizer tank 43, which has a first inlet 44 and a third outlet 45. The mixing tank 8 has a second inlet, and the second inlet and the third outlet 45 are connected by a fourth connecting pipe 46. A first rotating shaft 47 is rotatably connected to the fertilizer tank 43, and a first spiral blade 48 is fixedly connected to the first rotating shaft 47. Both the first rotating shaft 47 and the first spiral blade 48 extend into the fourth connecting pipe 46. A third motor 49 is fixedly connected to the fertilizer tank 43, and the output shaft of the third motor 49 is fixedly connected to the first rotating shaft 47.

[0048] The fertilizer bin 43 contains phosphate fertilizer in powder form. The first inlet 44 is used to feed the phosphate fertilizer into the fertilizer bin 43. The third motor 49 drives the first rotating shaft 47 to rotate, and the first rotating shaft 47 drives the first spiral blade 48 to rotate. The bottom of the fertilizer bin 43 is tilted downwards, and the third outlet 45 is at the lowest position on the ground. The gap between the first spiral blade 48 and the fourth connecting pipe 46 is very small, so the phosphate fertilizer will not fall out of the gap between the first spiral blade 48 and the fourth connecting pipe 46. When the third motor 48 drives the first spiral blade 48 to rotate, it will feed the phosphate fertilizer into the fourth connecting pipe 46. The continuous rotation of the first spiral blade 48 will cause the phosphate fertilizer to fall out of the fourth connecting pipe 46.

[0049] The design is further optimized by fixing an air pump 50 to the mixing tank 8 and opening an air inlet on the fourth connecting pipe 46. The air pump 50 and the air inlet are connected through an air supply pipe 51. The air inlet is tilted downward and is located below the first spiral blade 48.

[0050] The air pump 50 is used to blow air into the fourth connecting pipe 46. When the phosphate fertilizer falls into the fourth connecting pipe 46, the airflow will disperse the phosphate fertilizer, making it easier for the phosphate fertilizer to adhere to more milkvetch seeds.

[0051] Further optimization of the scheme: the stirring mechanism includes a second rotating shaft 52, which is rotatably connected inside the stirring tank 8. A fourth motor is fixedly connected to the outside of the stirring tank 8, and the output shaft of the fourth motor is fixedly connected to the second rotating shaft 52. A first connecting plate 54 is fixedly connected to the outside of the second rotating shaft 52, and a first arc-shaped plate 55 is fixedly connected to the first connecting plate 54. A fourth discharge port is opened on the stirring tank 8. The discharge mechanism includes a second arc-shaped plate 56, which is rotatably connected to the fourth discharge port. The second arc-shaped plate 56 is used to seal the fourth discharge port. The second arc-shaped plate 56 is detachably connected to the stirring tank 8. The collection box 10 is located below the fourth discharge port. The feeding mechanism 9 is an auger screw conveyor. Several first support legs 57 are fixedly connected to the outer protective box 1, and several second support legs 58 are fixedly connected to the stirring tank 8.

[0052] The fourth motor (not shown in the figure) drives the second rotating shaft 52 to rotate, the second rotating shaft 52 drives the first connecting plate 54 to rotate, the first connecting plate 54 drives the first arc plate 55 to rotate, the second arc plate 56 is located on the fourth discharge port, the fourth discharge port is located at the bottom of the mixing tank 8. When the first arc plate 55 rotates, the seeds on the second arc plate 56 will be loaded into the first arc plate 55 and fall to the other side as the first arc plate 55 rotates. This can turn over the seeds at the bottom, so that more seeds are attached to the phosphate fertilizer. The screw conveyor is existing technology, and the locking and opening / closing of the second arc plate 56 and the fourth discharge port are also existing technologies.

[0053] A method for seed dressing with milkvetch phosphate fertilizer includes:

[0054] Step 1: Place the milkvetch seeds into the seed box 2. The seeds will enter the outer shell 3 through the first connecting tube 14.

[0055] Step 2: Start the first motor 5 and the second motor 6. The seeds of milkvetch enter the outer shell 3. Driven by the first motor 5, the third gear 28 rotates. The third gear 28 drives the second gear 53 and the round rod 24 to rotate, thereby causing the round rod 24 and the ball 25 to rotate. The second motor 6 drives the first gear 19 to rotate. The first gear drives the first gear ring 16 to rotate, thereby causing the second motor 6 to drive the neck shell 11 and the expansion shell 12 to rotate. The inwardly contracting neck shell 11 will approach the round rod 24. When the milkvetch seeds enter between the round rod 24 and the neck shell 11, they will be rubbed for the first time. As the seeds continue to slide downward, the milkvetch seeds will be rubbed for the second time between the expansion shell 12 and the ball 25. At the same time, the outer shell 3 and the friction body 4 rotate in opposite directions, which can accelerate the friction on the seeds and make the seed surface rough.

[0056] Step 3: Start the spraying mechanism. Seeds enter the spray box 34. Pressure pump 41 pumps the adhesive solution to the atomizing nozzle 38. The adhesive is sprayed out through the atomizing nozzle 38 and sprayed onto the seed surface. The seed surface becomes rough after friction, making it easier for the adhesive to adhere. After the adhesive is sprayed in the spray box 34, the seeds will fall into the feeding mechanism 9 through the second discharge port 42, and then the feeding mechanism 9 will transport the seeds.

[0057] Step 4: Seeds enter the feeding mechanism from the spraying mechanism and then into the mixing tank 8. The third motor 49 drives the first rotating shaft 47 to rotate, which in turn drives the first spiral blade 48 to rotate. When the first spiral blade 48 rotates, it sends phosphate fertilizer into the fourth connecting pipe 46. The air pump 50 blows air into the fourth connecting pipe 46. When the phosphate fertilizer falls into the fourth connecting pipe 46, the airflow will disperse the phosphate fertilizer, making it easier for the phosphate fertilizer to adhere to more milkvetch seeds. At the same time, the mixing mechanism will make the phosphate fertilizer adhere more evenly to the surface of the milkvetch seeds. The second arc plate 56 is opened, allowing the mixed milkvetch seeds to enter the collection tank 10.
