Description

Technical Field

[0001] The present invention relates to the technical field of seed processing, and more specifically to a seed treatment process. Background Art

[0002] Seed pelleting processing is to orderly and layer-by-layer coat effective ingredients such as pesticides, fertilizers, growth regulators, water retainers, oxygenators and some auxiliary materials onto seeds by using seed pelleting equipment, so that the seeds are pelletized, which can effectively achieve pre-sowing plant protection, fertilization and pesticide application in the field, and achieve the purpose of ensuring seedling growth and regulating crop growth.

[0003] Traditional seed pelleting equipment usually adopts a processing bin with a fixed capacity and a single stirring method. Although this design is simple and easy to implement, it has obvious limitations in actual use. First, due to the fixed space of the processing bin, local accumulation or uneven mixing of seeds and coating materials is likely to occur during the mixing process, especially in the edge and bottom areas of the processing bin, where the contact between seeds and coating materials is insufficient, resulting in unsatisfactory coating effects. Second, the traditional equipment has a single stirring method and cannot dynamically adjust the mixing conditions according to the characteristics of seeds and coating materials, resulting in low mixing efficiency and unstable pelleting quality. Summary of the Invention

[0007] A plurality of spiral stirring vanes are fixedly connected around the inner wall of the cylinder.

[0008] A plurality of spiral grooves matching the spiral stirring vanes are formed on the opposite surfaces of the two sleeves.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] As Figures 1 to 8 shown:

[0026] A seed pelleting device, comprising a base 101, a cylinder frame 201 is installed on the base 101, a cylinder 301 is rotatably connected to the cylinder frame 201 in a limited way, two sleeves 401 are slidably connected to both sides of the cylinder 301, two electric push rods II 202 are symmetrically fixed on the cylinder frame 201, and the telescopic ends of the two electric push rods II 202 are respectively rotatably connected to the outer ends of the two sleeves 401 in a matching way;

[0027] A stirring chamber is formed between the two sleeves 401 and the cylinder 301. Control the telescopic end of one of the electric push rods II 202 to extend to drive the sleeve 401 to slide out of the cylinder 301, and one side of the cylinder 301 is exposed. Put seeds and coating materials into the cylinder 301. Control the electric push rod II 202 to make the sleeve 401 slide back into the cylinder 301, and then control the cylinder 301 to rotate reciprocally to mix the seeds and coating materials in the cylinder 301. During the continuous rotation of the cylinder 301, control the two electric push rods II 202 to continuously extend and retract to drive the two sleeves 401 to continuously approach and move away from each other in the cylinder 301, so as to continuously change the space in the stirring chamber. When the space in the stirring chamber becomes larger, the seeds can be more dispersed, so that the seeds can contact more coating materials; when the space in the stirring chamber becomes smaller, the coating materials can be more tightly attached to the surface of the seeds through pressure or friction. Moreover, the change of the space in the stirring chamber promotes the seeds and coating materials to continuously roll and redistribute in the stirring chamber, and then by dynamically adjusting the space of the processing chamber, the seeds and coating materials can be more fully contacted and mixed, so as to improve the mixing uniformity and coverage rate. Continuously change the space in the stirring chamber. When the space changes, the coating materials and seeds are continuously redistributed and compressed, maintaining the fluidity and uniformity of the coating materials and seeds, avoiding local accumulation or uneven mixing of the seeds and coating materials. This dynamic stirring helps to prevent the coating materials from caking. Further, the continuous change of the space increases the relative movement between the seeds and the coating materials, making the coating materials more tightly attached to the surface of the seeds.

[0028] As Figure 7 shown:

[0029] A plurality of spiral stirring blades 303 are welded around the inner wall of the cylinder 301;

[0030] During the rotation of the cylinder 301, the plurality of spiral stirring blades 303 inside are driven to continuously rotate. The plurality of spiral stirring blades 303 continuously turn the coating materials and seeds, making the coating materials and seeds form a continuous "spiral belt", so that the coating materials can be more evenly distributed on the surface of the seeds, avoiding local accumulation or loss of the coating materials in the processing chamber.

[0031] As Figures 8 to 10 shown:

[0032] On the opposite faces of the two sleeves 401, a plurality of spiral grooves 404 adapted to the spiral stirring vanes 303 are formed;

[0033] The two ends of each spiral stirring vane 303 are respectively slidably connected in the corresponding spiral grooves 404 on the two sleeves 401, and the sleeve 401 can rotate relative to the telescopic end of the electric push rod II 202. In this way, when the cylinder 301 rotates, the two sleeves 401 on both sides are driven to rotate synchronously by the plurality of spiral stirring vanes 303. At the same time, the two sleeves 401 can also rotate and move inward along the spiral direction of the spiral stirring vanes 303, thus not interfering with the dynamic adjustment of the space in the stirring bin;

[0034] When it is necessary to slide the sleeve 401 into the cylinder 301, control the telescopic end of the electric push rod II 202 to drive the sleeve 401 to move towards the cylinder 301. During this period, manually control the rotation of the sleeve 401 to align the spiral groove 404 on the sleeve 401 with the spiral stirring vane 303, so that the sleeve 401 can smoothly slide into the cylinder 301.

[0035] As Figures 7 to 8 shown:

[0036] On the outer ends of the two sleeves 401, trapezoidal rings 402 are integrally formed. On the two trapezoidal rings 402, sliding seats 405 are slidably connected. The two sliding seats 405 are respectively fixedly connected to the telescopic ends of the two electric push rods II 202 through flanges and screws;

[0037] The lower end of the sliding seat 405 is provided with a trapezoidal groove adapted to the shape of the trapezoidal ring 402. The sliding seat 405 is slidably connected to the trapezoidal ring 402 through the trapezoidal groove. The trapezoidal ring 402 is formed by welding two semi - rings with the same shape relatively, which is convenient for sleeving the sliding seat 405 on the trapezoidal ring 402;

[0038] When the telescopic end of the electric push rod II 202 extends or retracts, the sleeve 401 is driven to slide in the cylinder 301 through the cooperation of the sliding seat 405 and the trapezoidal ring 402. At the same time, the trapezoidal ring 402 can rotate relative to the sliding seat 405. Therefore, when the cylinder 301 drives the sleeve 401 to rotate through the spiral stirring vane 303, the trapezoidal ring 402 rotates at the lower end of the sliding seat 405, thus not interfering with the movement and rotation of the sleeve 401; Further, when the two sleeves 401 slide closer to or away from each other in the cylinder 301, the spiral stirring vane 303 can slide in the corresponding spiral groove 404. Therefore, when the distance between the two sleeves 401 changes, the two sleeves 401 can still rotate in the cylinder 301 without interference;

[0039] The two continuously moving sleeves 401 can rotate within the cylinder 301 and will not interfere with the spiral stirring blades 303. In this way, the multiple spiral stirring blades 303 can stir and mix the seeds and coating materials, and the two moving sleeves 401 can continuously and dynamically adjust the space of the processing chamber, enabling the seeds and coating materials to come into full contact and mix. Furthermore, with the combined effect of these two effects, the coating material can adhere more closely to the seed surface, improving the coating efficiency of the seeds.

[0040] As Figure 3 , 10 to 11 show:

[0041] Two crossbeams 203 are symmetrically welded on the base 101. Pipe racks 207 are installed on both of the two crossbeams 203. A spray pipe 208 is detachably connected between the two pipe racks 207 by screws. The spray pipe 208 is in sealed sliding connection with the two sleeves 401;

[0042] After the cylinder 301 starts to rotate, an external water pipe is connected to one end of the spray pipe 208, so that pressurized water sprays out from multiple nozzles evenly distributed on the spray pipe 208. The moisture is sprayed onto the seeds, enabling the seeds to be evenly wetted during the rotation and tumbling process, promoting sufficient contact between the coating material and the seeds, and enabling the coating material to uniformly wrap on the seed surface, improving the pelleting efficiency of the seeds; at the same time, the water vapor spray provides a moderately humid environment for the seed surface, making the coating material more likely to adhere and be evenly distributed on the seed surface. The multiple spiral stirring blades 303, through their own spiral structures, enable the seeds and coating materials to come into full contact and be evenly mixed during the stirring process, avoiding local accumulation or lack of the coating material, thereby forming a uniform and dense coating layer; the synergistic effect of the water vapor spray and the spiral stirring blades 303 significantly improves the coating efficiency. The wetting effect of the water vapor enables the coating material to be more quickly and evenly dispersed, while the continuous stirring of the spiral stirring blades 303 ensures the full combination of the coating material and the seeds, reducing the coating time, while improving the integrity and quality of the coating; the water vapor spray effectively inhibits the dust generated during the coating process, improves the working environment, and at the same time reduces the waste of the coating material; the uniform stirring of the spiral stirring blades 303 further reduces the unnecessary loss of the coating material, improves the resource utilization rate, and meets the requirements of environmental protection and sustainable development.

[0043] Furthermore, this implementation method has wide applicability and can adapt to the needs of different types and sizes of seeds and various coating materials; by adjusting the water vapor spray amount and the rotation speed of the spiral stirring blades 303, the coating effect can be flexibly adjusted to meet the process requirements of different seed pelleting.

[0044] To prevent the two sleeves 401 from approaching each other when the space in the mixing bin is dynamically changed, and the nozzles on the spray pipe 208 spray water outside the mixing bin, the spray pipe 208 is only provided with nozzles in a small section at the middle position, that is, when the distance between the two sleeves 401 is such that the nozzles are still between the two sleeves 401.

[0045] As Figures 9 to 10 shown:

[0046] As a further optimization, in order to expand the position length of the nozzles provided on the spray pipe 208, improve the water spraying effect, and at the same time prevent water from being sprayed outside the sleeve 401 to wet the equipment; rubber sleeves 403 slidably connected to the spray pipe 208 are connected to the cores of the two sleeves 401.

[0047] The spray pipe 208 located inside the cylinder 301 is no longer limited to having nozzles only in a small section at the middle position, but is evenly provided with a plurality of nozzles in a larger length range. When the two sleeves 401 move closer to each other, the two rubber sleeves 403 can block the nozzles on both sides of the spray pipe 208 exposed outside the sleeve 401, thereby preventing water from being sprayed outside the sleeve 401 to wet the equipment and causing waste of water resources at the same time.

[0048] As Figure 10 shown:

[0049] As a further optimization, the spray pipe 208 does not necessarily have to spray water. The spray pipe 208 can also spray liquid fertilizers, pesticides, etc., thereby expanding the scope of use of the equipment. For example, for seeds of corn, wheat, beans, crucifers such as rape and sunflower, a colorful film coating agent can be sprayed, so as to quickly form a film, with uniform and firm coating, suitable for mechanized sowing. For seeds of soybean, Chinese cabbage, potato, corn, etc., a chitosan solution can be sprayed, so as to promote root development, enhance stress resistance, such as drought resistance and disease resistance, and improve germination rate and yield. For seeds of wheat, corn, soybean, rice, vegetables, etc., a suspension of rhubarb extract can be sprayed, so as to promote root development, enhance stress resistance, such as drought resistance and disease resistance, and inhibit fungi and soil-borne diseases, such as take-all and root rot.

[0050] As Figure 10 shown:

[0051] As a further optimization, the spray pipe 208 does not necessarily have to spray water. The spray pipe 208 can also spray gas. By spraying gas during the seed coating stirring process, the following can be achieved: 1. Form a vortex to break the local agglomeration of the coating material and promote the uniform dispersion of particles, improving the coating quality; 2. The airflow generated by spraying gas can carry the coating material through the gaps between the seeds, improving the uniformity of the coverage on the seed surface and enhancing the coating quality; 3. For some coating processes, spraying gas can accelerate the drying of the coating agent and prevent the liquid medicine from coking in a high-temperature environment, such as reducing the decomposition rate of urea-based fertilizers; 4. The airflow generated by spraying gas can also take away the excess moisture, control the water content of the seeds below 12%, and prevent the seeds from mildewing.

[0052] Such as Figure 10 shown:

[0053] As a further optimization, solenoid valves can also be added to both sides of the spray pipe 208 respectively. One side of the spray pipe 208 is connected to a liquid spraying device, such as a water pump, and the other side of the spray pipe 208 is connected to a gas spraying device, such as an air pump. When the spray pipe 208 sprays liquid, the liquid spraying device works, the solenoid valve at this end opens, and the solenoid valve on the other side closes, so as to achieve spraying only liquid into the stirring bin. When the spray pipe 208 sprays gas, the gas spraying device works, the solenoid valve at this end opens, and the solenoid valve on the other side closes, so as to achieve spraying only gas into the stirring bin. Through intermittent control, the liquid spraying and gas spraying are separated by intervals and cyclically sprayed, so as to achieve the common cooperation of liquid spraying and gas spraying during the coating process. Furthermore, it can not only enable the full combination of the coating material and the seeds, reduce the coating time, improve the integrity and quality of the coating, but also avoid the local agglomeration of the coating material, promote the uniform dispersion of particles, and enhance the coating quality.

[0054] Such as Figure 10 shown:

[0055] As a further optimization, taking the center of the cylinder 301 as the boundary, the spray pipe 208 can be divided into two non-connecting left and right sides, and the spray pipe 208 can be divided into a liquid spray pipe and a gas spray pipe, so that the liquid spray pipe on one side can spray liquid and the gas spray pipe on the other side can spray gas. Or the spray pipe 208 can be divided into upper and lower halves that do not communicate with each other, so as to achieve that one half is a liquid spray pipe for spraying liquid and the other half is a gas spray pipe for spraying gas. Thus, it can achieve spraying gas or liquid simultaneously, or spraying gas or liquid at intervals. It can completely decide when to spray gas, when to spray liquid, or spray simultaneously according to the process requirements.

[0056] Taking the example of spraying water and jetting air simultaneously during the seed coating process: As described above, water is sprayed onto the seeds, enabling the seeds to be evenly moistened during rotation and tumbling, promoting sufficient contact between the coating material and the seeds, allowing the coating material to uniformly wrap around the seed surface, and improving the pelleting efficiency of the seeds. However, if too much water is sprayed, it will cause the seed moisture content to be too high, leading to easy mildew of the seeds. When spraying water and jetting air simultaneously, the airflow generated by jetting air can also carry away the excess water, controlling the seed moisture content below 12% and preventing seed mildew. By jetting air during the seed coating stirring process, the following can also be achieved: 1. Forming a vortex to break the local agglomeration of the coating material into lumps, promoting uniform dispersion of the particles and improving the coating quality; 2. The airflow generated by jetting air can carry the coating material through the gaps between the seeds, enhancing the uniformity of the coverage on the seed surface and improving the coating quality; 3. For certain coating processes, jetting air can accelerate the drying of the coating agent, avoiding coking of the liquid medicine caused by high temperature, such as the reduction of the decomposition rate of urea-based fertilizers. In addition, spraying water may also cause local humidity differences to trigger the peeling of the coating layer. By jetting air while spraying water and with the cooperation of the continuous flipping of the seeds and the coating material under the rotation of the spiral stirring blade 303, the water vapor can be more evenly attached to the seeds and the coating material, thereby reducing the local humidity difference and reducing the proportion of coating layer peeling.

[0057] In the actual production process, water can be replaced with other liquids according to processing needs, such as liquid fertilizers, pesticides, etc.

[0058] As Figure 5 and 7 shown:

[0059] A motor 205 is fixedly connected to the cylinder frame 201 through a motor frame and bolts. The output shaft of the motor 205 is fixedly connected with a gear 206, and a gear ring 302 meshing and drivingly connected with the gear 206 is fixedly connected to the outer wall of the cylinder 301 through screws;

[0060] Controlling the motor 205 to start and drive the gear 206 to rotate. The gear 206 drives the cylinder 301 to rotate on its own on the cylinder frame 201 through meshing with the gear ring 302, thereby realizing the uniform mixing between the seeds and the coating material inside the cylinder 301.

[0061] As Figures 3 to 5 shown:

[0062] A hinge seat 103 rotatably connected to the cylinder frame 201 is fixedly connected to the base 101. An electric push rod I 104 is fixedly connected to the base 101. A chute frame 204 is fixedly connected to the lower end of the cylinder frame 201. A push rod 105 slidably connected inside the chute frame 204 is fixedly connected to the telescopic end of the electric push rod I 104;

[0063] Collection boxes 102 are placed below both sides of the hinge seat 103 on the base 101;

[0064] When it is necessary to discharge the pelleted seeds, control one of the sleeves 401 to slide out of the cylinder 301, so that one side of the cylinder 301 is opened. Then control the telescopic end of the electric push rod I 104 to drive the lever 105 to move up or down. The lever 105 slides in the chute frame 204 and drives the cylinder frame 201 to rotate right-downward or left-downward around the axis of the hinge with the hinge seat 103. The pelleted seeds are discharged into the corresponding collection box 102 on the base 101 under the action of gravity.

[0065] Furthermore, when the spiral stirring blades 303 rotate, they push the material to move axially and push all the materials to one end of the cylinder 301. At this time, the cylinder 301 can be controlled by the lever 105 to rotate downward toward the end where the materials gather. After the sleeve 401 on this side slides out of the cylinder 301, the cylinder 301 on this side is exposed, so as to realize the rapid discharge of all the materials under the action of gravity. During the process of material discharge, the multiple spiral stirring blades 303 continuously rotate and stir, which can further accelerate the speed of material evacuation. At the same time, the multiple rotating spiral stirring blades 303 can scrape and discharge all the materials remaining on the inner wall of the cylinder 301.

[0066] Even further, when the seeds and coating materials are being coated in the cylinder 301, the cylinder 301 can be controlled by the lever 105 to rotate reciprocally left and right, so that the seeds and coating materials slide reciprocally left and right in the cylinder 301. At the same time, in cooperation with the multiple spiral stirring blades 303 continuously stirring the seeds in a spiral manner, the combined action of the inclined rotation of the cylinder 301 and the stirring of the spiral stirring blades 303 can quickly disperse the materials and evenly distribute them in the cylinder 301, avoiding the agglomeration and deposition of the materials. The combination of sliding and stirring makes the movement of the materials in the cylinder 301 more intense and sufficient, thus improving the stirring efficiency. Secondly, the centrifugal force generated during the rotation of the spiral stirring blades 303 helps to evenly distribute the materials throughout the cylinder 301, making the mixing between the components more uniform and thorough; the inclined rotation of the cylinder 301 also promotes the mixing of the materials in the vertical direction, further enhancing the bonding effect between the seeds and the coating materials.

[0067] As Figure 11 shown:

[0068] The cross beam 203 and the pipe rack 207 are detachably connected by screws; it is convenient to detach the pipe racks 207 on both sides, and then pull out the spray pipe 208 from the two pipe racks 207. In this way, the sleeves 401 on both sides can be removed, which is convenient for cleaning the inside of the cylinder 301.

[0070] a: Control the telescopic end of one of the electric push rods II 202 to extend, drive the sleeve 401 to slide out of the cylinder 301, put seeds and coating materials into the cylinder 301, and control the sleeve 401 to slide back into the cylinder 301;

[0071] b: Control the motor 205 to start and drive the gear 206 to rotate. The gear 206 drives the cylinder 301 to rotate by meshing with the gear ring 302;

[0072] c: The two electric push rods II 202 continuously extend and retract to drive the two sleeves 401 to continuously approach and move away from each other in the cylinder 301, continuously changing the space in the mixing bin;

[0073] d: Control the sleeve 401 on one side to slide out of the cylinder 301. The telescopic end of the electric push rod I 104 drives the dial rod 105 to move downward. The dial rod 105 slides in the chute frame 204 to drive the left side of the cylinder frame 201 to rotate downward, discharging the pelleted seeds into the collection box 102.
