[0002] Seed coating is an agricultural technology. Its core purpose is to coat the surface of seeds with a layer of seed coating agent with specific functions before sowing. Seed coating can promote seed germination and enhance seed resistance. At the same time, it slowly releases various active ingredients contained in the seed coating agent, which are gradually absorbed by the seed seedlings, thereby achieving the effect of preventing and controlling seedling diseases and pests, promoting growth and development, and increasing crop yields.

[0003] The existing coating method uses a stirring device to stir the seeds and coating agent added inside. The number of seeds and the amount of coating agent put in before stirring cannot be determined, and the degree of completion of the seed coating cannot be accurately guaranteed or excess coating agent causes waste of coating agent. After the stirring is completed, the device needs to be stopped to discharge the coated seeds inside the device before the next seed coating can be carried out. Summary of the invention

[0015] Beneficial effects: 1. The seed coating part contains a coating agent for coating seeds. The rotating part drives the push plate to rotate to pick up the seeds immersed in the coating agent. The vibration component vibrates and shakes off the excess coating agent on the picked-up seeds through the rotating part. The push plate continues to push the seeds to be discharged from the discharge part.

[0016] When the drying bin assembly rotates, due to the centrifugal force, the seeds will move upward along the inner wall of the drying bin assembly. At the same time, because the air outlet blows toward the bottom of the drying bin body, it will flow back upward along the inner wall of the drying bin body, driving the seeds to move upward along the wall surface. At the same time, the seeds will have a tendency to move toward the periphery of the drying bin body under the action of centrifugal force. Under the action of gas backflow, the movement trend of the seeds will be intensified and flow back upward along the wall surface. At the same time, when the drying bin body rotates, the redirecting distribution part will change the movement direction of the seeds downward. The seeds form a movement area with a certain range in the two states, and the seeds in this movement area are almost disordered under the combined influence of multiple movement trends. It can fully contact with the airflow and effectively separate the stuck seeds in the disordered movement. The air is discharged through the air outlet and forms an ejection effect, increasing the air intake of the air duct. After the gas is heated by the heat source part, it is blown out from the outlet end of the air duct and reacts with the bottom of the drying bin body before flowing back from the surrounding wall. It can play a good role in seed drainage and drying the seeds at the same time. In conjunction with the heat collecting part, it can effectively enhance the heat radiation before the gas is blown out, increase the temperature of the wind, and thus improve the drying efficiency. Through the setting of the ejection part, the wind flow can be increased under the premise of increasing the temperature, making the movement effect of the seeds more disordered, which is beneficial to reducing adhesion and improving the drying efficiency.

[0022] Referring to the accompanying drawings, this embodiment is described, a seed coating and drying system, comprising: The seed coating part 1 is a hollow shell with a coating agent inside; A discharge portion 6 is provided on the seed coating portion 1 and communicated with the cavity, wherein the discharge portion 6 is located between the near-ground end of the coating portion 1 and the coating agent liquid surface; A seed pushing component 5 rotates inside the seed coating part 1, wherein the seed pushing component 5 comprises a rotating part 5-1, the rotating part 5-1 is axially provided with a plurality of pushing plates 5-2 which are in contact with the inner wall of the cavity of the seed coating part 1, the pushing plates 5-2 are provided with a liquid leakage part 5-3, when the rotating part 5-1 rotates, the coated seeds are discharged from the discharge part 6 through the pushing plates 5-2, and the pushing plates 5-2 are provided with a shielding part 5-4 which prevents the discharged coated seeds from flowing back; A vibration component 7, arranged inside the seed coating part 1, vibrates the rotating part 5-1; The reseeding component 4 is arranged on the seed coating part 1 to push the pushing plate 5-2 that has drained the coated seeds to replenish the seeds to be coated. The reseeding component 4 is connected to the rotating part 5-1.

[0023] The seed coating part 1 contains a coating agent for coating seeds. The rotating part 5-1 drives the pushing plate 5-2 to rotate to pick up the seeds immersed in the coating agent. The coating agent falls back to the previous position through the leakage part 5-3. At the same time, the vibration component 7 vibrates and shakes off the excess coating agent on the picked up seeds through the rotating part 5-1. The pushing plate 5-2 continues to push the seeds to be discharged from the discharge part 6. The shielding part 5-4 can prevent the discharged coated seeds from flowing back into the coating part 1. When the seeds on the pushing plate 5-2 are discharged, the reseeding component 4 pushes the pushing plate 5-2 that has discharged the coated seeds to supplement the seeds to be coated between the plates. The newly added seeds are continuously and accurately coated and discharged without stopping the machine, thereby improving the seed coating effect while also improving the coating efficiency.

[0024] In this embodiment, the rotating part 5-1 is a rotating column arranged on the rotating shaft 2, the angle between the pushing plate 5-2 and the extended line of the radius of the rotating part 5-1 is an acute angle, the tangent of the rotating direction of the rotating part 5-1 is toward the pushing plate 5-2, the rotating shaft 2 is connected with the reseeding component 4 through the transmission component 3, the rotating shaft 2 is connected with the matching servo motor through the coupling, the servo motor drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the rotating part 5-1 which is the rotating column to rotate, the rotating part 5-1 drives the pushing plate 5-2 to rotate, the rotating pushing plate 5-2 picks up the seeds in the coating agent, and then the rotating pushing plate 5-2 brings The seeds continue to rotate. When the pushing plate 5-2 containing the coated seeds rotates to a vertical horizontal plane, the coated seeds on the current pushing plate 5-2 fall on the back of the previous adjacent pushing plate 5-2. The pushing plate 5-2 continues to rotate. When the pushing plate 5-2 containing the coated seeds on the back rotates to the discharge portion 6 position, the coated seeds on the back of the pushing plate 5-2 will be discharged from the discharge portion 6. The rotation direction of the rotating portion 5-1 allows the coated seeds on the pushing plate 5-2 to be discharged after bypassing most of the circle. This can remove excess coating agent on the coated seeds as much as possible, and avoid waste of coating agent after the seeds are completely coated with the coating agent.

[0025] In this embodiment, the shielding portion 5-4 is a beveled arc plate and fits the inner wall of the cavity of the seed coating portion 1. The shielding portion 5-4 is arranged on the end face of the pushing plate 5-2 on the side that holds up the seeds in the coating agent. When the pushing plate 5-2 rotates, it drives the shielding portion 5-4 to rotate. The rotating shielding portion 5-4 scoops up the seeds in the coating agent to prevent the pushing plate 5-2 from being damaged by too many seeds when it is close to the inner wall of the cavity of the seed coating portion 1. The shielding portion 5-4 can cover the seed inlet end of the discharge portion 6 to prevent the coated seeds that fall into the discharge portion 6 from flowing back into the seed coating portion 1, wherein the discharge portion 6 is a seed discharge mouth that gradually closes.

[0026] In this embodiment, the liquid leakage portion 5 - 3 is a strip-shaped groove along the rotation direction of the push plate 5 - 2 , which can prevent the seeds on the push plate 5 - 2 from being stuck on the liquid leakage portion 5 - 3 .

[0027] In this embodiment, a blocking bar 5-5 is provided between two adjacent pushing plates 5-2 to prevent the coated seeds from being stuck between the two adjacent pushing plates 5-2 during the transmission process.

[0028] In this embodiment, the vibration assembly 7 includes a storage groove 7-1, a first spring 7-2, an impact column 7-3, an impact arc groove 7-4 and a lifting ramp block 7-5. At least one of the storage grooves 7-1 is arranged inside the seed coating part 1, the impact column 7-3 slides inside the storage groove 7-1, the first spring 7-2 is arranged between the storage groove 7-1 and the impact column 7-3, a plurality of impact arc grooves 7-4 are arranged on the side end surface of the rotating part 5-1, and the lifting ramp block 7-5 is arranged inside the impact arc groove 7-4. The inclined surface of the lifting ramp block 7-5 is opposite to the inclination angle of the push plate 5-2, and the rotating part 5-1 is rotated. The rotating part 5-1 drives the impact arc groove 7-4 to rotate, and the impact arc groove 7-4 squeezes the impact column 7-3 to move into the storage groove 7-1 by raising the inclined block 7-5 and compresses the first spring 7-2. When the impact column 7-3 rotates from one storage groove 7-1 to another adjacent storage groove 7-1, the compressed first spring 7-2 pushes the impact column 7-3 to impact the rotating part 5-1, thereby causing the rotating part 5-1 to vibrate. The vibrating rotating part 5-1 drives the pushing plate 5-2 to vibrate together, so that the excess coating agent of the coated seeds on the pushing plate 5-2 falls off.

[0029] In this embodiment, the reseeding component 4 includes a seed pushing cylinder 4-1, which is arranged on the seed coating part 1 on the same side as the discharge part 6 and is connected to the cavity inside the seed coating part 1, and the seed pushing cylinder 4-1 is located between the discharge part 6 and the seed pushing cylinder 4-1. The seed pushing cylinder 4-1 is connected to the seed replenishing device through a connecting pipe 4-2, and a spiral pushing plate 4-4 is rotated inside the seed pushing cylinder 4-1. The spiral pushing plate 4-4 is connected to the transmission component 3 through a connecting shaft 4-3. When the seed pushing component 5 discharges seeds, the rotating shaft 2 drives the connecting shaft 4-3 to rotate through the transmission component 3, and the connecting shaft 4-3 drives the spiral pushing plate 4-4 to rotate. The rotating spiral pushing plate 4-4 continuously pushes the seeds between the two pushing plates 5-2, thereby making the amount of seeds between the two pushing plates 5-2 quantitative, so that the effect of seed coating is better.

[0030] In this embodiment, the transmission assembly 3 includes a first pulley 3-1, a second pulley 3-2 and a transmission belt 3-3. The first pulley 3-1 is arranged on the rotating shaft 2, and the second pulley 3-2 is arranged on the connecting shaft 4-3.

The rotating shaft 2 drives the first pulley 3-1 to rotate, the first pulley 3-1 drives the second pulley 3-2 to rotate through the transmission belt 3-3, and the second pulley 3-2 drives the connecting shaft 4-3 to rotate.

[0031] In this embodiment, a drain valve 9 is provided at the ground inlet end of the seed coating part 1, and the seed coating part 1 is provided with a solenoid valve 8 for replenishing the coating agent. A sensor for monitoring the amount of coating agent is provided on the seed coating part 1, and the sensor controls the switch of the solenoid valve 8. The sensor monitors the amount of coating agent inside the coating part 1. When the coating agent is less than a predetermined amount, the sensor drives the solenoid valve 8 to open so that the coating agent is replenished into the seed coating part 1. The excess coating agent inside the seed coating part 1 can be discharged through the drain valve 9, and water can be added to the seed coating part 1 through the solenoid valve 8 to clean the inside of the seed coating part 1.

[0032] Drying mechanism, comprising: The driving component 10 includes a rotating support part 10-3, a plurality of air ducts 10-4 arranged on the rotating support part 10-3, an air outlet part 10-5 arranged in each air duct 10-4 for outputting air to the outlet end of the air duct 10-4, and a heat source part 10-6 coupled to the air duct 10-4; the rotating support part 10-3 is specifically a rotating shaft. The setting of the rotating shaft here not only provides a rotating driving force for the drying bin component 3, but also needs to provide a relative sliding path for the drying bin component 3. Therefore, the rotating support part 10-3 needs to have a certain cross-sectional shape so that when it rotates, it can drive the drying bin component 3 to rotate synchronously without affecting the relative sliding between the two. In the present application, the cross-section of the rotating support part 10-3 adopts two ellipses intersecting to form a special-shaped shaft with a smooth transition surface, and its cross-sectional shape is the same as that of the rotating support part 10-3. Fig. 20 The opening shape of the sliding matching part 12-4 is the same as that of the rotating support part 10-3. After the two are matched, the rotating support part 10-3 can drive the sliding matching part 12-4 to rotate through the matching, and at the same time, the two can slide smoothly along the axial direction. The material of the rotating support part 10-3 is reasonably selected according to actual conditions, and it needs to meet the driving strength. At the same time, the surface should be smoothed to reduce the friction coefficient.

[0033] As for the air duct 10-4, the present application adopts the method of opening a channel in the rotating support part 10-3 for setting. According to actual needs, other forms can also be adopted. Specifically, two air ducts 10-4 are set and arranged in a circular symmetry relative to the axis of the rotating support part 10-3. The inlet end of the air duct 10-4 is set at a relatively high position, preferably inside the drying bin body 12-1 or near the feed port at the upper end of the drying bin body 12-1. The outlet end of the air duct 10-4 is set inside the drying bin body 12-1 and arranged toward the bottom of the drying bin body 12-1, so that the wind can be blown to the bottom of the drying bin body 12-1 and then flow back upward along the wall of the drying bin body 12-1.

[0034] For the air outlet 10-5, a fan or a nozzle with an integrated air pump can be used. According to actual needs, a component capable of discharging air can be set, and the corresponding connection method is reasonably selected according to actual needs. The air outlet of the air outlet 10-5 needs to be coaxially arranged in the air duct 10-4, so that when the high-pressure gas is ejected, it can form an ejection effect on the gas located at the rear of the air duct 10-4, thereby increasing the air intake at the inlet end of the air duct 10-4.

[0035] The heat source part 10-6 can be specifically arranged in the air duct 10-4 or at the outlet end of the air duct 10-4. The corresponding heat source form is selected according to the layout position. For example, if it is arranged in the air duct 10-4, the coil part of the hot wire can be selected on the inner wall of the air duct 10-4, or it can be arranged at the outlet end of the air duct 10-4 in the form of a hot coil.

[0036] The drive assembly 10 also includes a motor 10-1 and a reducer 10-2. The rotating end of the motor 10-1 is connected to the input end of the reducer 10-2, and the output end of the reducer 10-2 is connected to the rotating support 10-3. The rotating end of the motor 10-1 is connected to the input end of the reducer 10-2 through a coupling, and the output end of the reducer 10-2 is connected to the rotating support 10-3 through a coupling. The rotating support 10-3 is configured in the form of a rotating shaft. Specifically, when connected to the support assembly 2, the connecting portion of the rotating support 10-3 and the support assembly 11 is configured as an axis with a circular cross-sectional shape. This section of the axis is connected to the coaxial bearing seat of the support assembly 11, and the selection of the bearing seat should be able to resist axial force. In order to limit the sliding path of the sliding fitting part 12-4 and the drying chamber body 12-1, two bosses spaced a certain distance apart along the axial direction are arranged on the rotating support part 10-3, the sliding fitting part 12-4 is slidably arranged between the two bosses, and the elastic member 10-9 is arranged between the sliding fitting part 12-4 and the boss located on the lower side. When the elastic member 10-9 is in a non-compressed state, the upper end surface of the sliding fitting part 12-4 abuts against the lower end surface of the boss located on the upper side.

[0037] The driving assembly 1 also includes a heat collecting part 10-7 and an ejection part 10-8. The heat collecting part 10-7 is arranged at the outlet end of all the air ducts 10-4 to collect the wind and then output it. The ejection part 10-8 is sleeved on the outer wall of the ejection part 10-8 and has a certain gap. The heat collecting part 10-7 is located as a whole in the middle of the ejection part 10-8, wherein the gas at the outlet end of the heat collecting part 10-7 is used to eject the gas in the ejection part 10-8.

[0038] The heat collecting part 10-7 is tapered as a whole, with the opening side located at the end with a smaller diameter and arranged toward the bottom of the drying bin body 12-1. As for the arrangement of the heat collecting part 10-7, it is tapered and cylindrical, and the inner wall of the side with a larger opening diameter is provided with an internal thread, which is connected to the end of the rotating support part 10-3 and the outlet end of the entire air duct 10-4 is accommodated inside, so that the heat of a part of the air flow will be radiated on the inclined wall surface of the heat collecting part 10-7, forming a scale effect, and a larger air volume and a higher temperature can be obtained when the gas is blown out. After the wind is blown out, due to the arrangement of the ejection part 10-8, the gas in the ejection part 10-8 in the back pressure area can be ejected and then the flow rate can be accelerated to impact the bottom of the drying bin body 12-1, which will drive the seeds gathered at the bottom of the drying bin body 12-1 to the rear side. Since the bottom wall of the drying bin body 12-1 is arc-shaped, the seeds will crawl upward along the wall surface. In the relative movement, the drying of the seeds can be accelerated, while the movement of the seeds is intensified and the bonding rate is reduced. The ejection part 10-8 is specifically configured as a hollow tube, which is sleeved on the outside of the heat collecting part 10-7.

[0039] The drying bin assembly 12 comprises a drying bin body 12-1 and a redirecting material distribution portion 12-2 arranged on the inner peripheral wall of the drying bin body 12-1, wherein the drying bin body 12-1 is axially slidably connected to the rotating support portion 10-3 by an elastic member 10-9, the outlet end of the air duct 10-4 faces the bottom of the drying bin body 12-1, and the redirecting material distribution portion 12-2 has a surface with a certain inclination angle on the side away from the bottom of the drying bin body 12-1 and the side close to the bottom; wherein the outlet end of the air duct 10-4 faces the bottom of the drying bin body 12-1, and the air outlet portion 10-5 outputs wind and is used to guide the gas in the air duct 10-4 to be blown out from the air duct 10-4 to the bottom of the drying bin body 12-1, and then flow back along the wall surface of the drying bin body 12-1 away from the bottom to drive the seeds to move upward, and the redirecting material distribution portion 12-2 is used to change the movement trend of the seeds toward the bottom through the surface with an inclination when the drying bin body 12-1 rotates. The redirecting material distribution part 12-2 can be an inclined arc plate, and the upper arc surface is conducive to the added seeds falling downward when rotating, and the lower arc surface can change the movement trend of the seeds to downward through relative movement with the seeds when rotating. The specific arc parameters are set according to actual conditions and need to be set in a way that is conducive to reducing the seed wear rate. Through the above settings, the redirecting material distribution part 12-2 is conducive to falling and redirecting the materials below.

[0040] In this embodiment, the drying device further includes a support assembly 11, the rotating support portion 10-3 is rotatably connected to the support assembly 11, and the motor 10-1 and the reducer 10-2 are both connected to the support assembly 11. The support assembly 11 is provided to provide support, and the arrangement of the device requires that a certain counterweight be provided on the support assembly 11, which is fixed in the working position by anchor bolts. The support assembly 11 needs to meet the structural strength and meet the vibration generated by the up and down floating of the support and drying bin body 12-1.

[0041] In this embodiment, the drying bin body 12-1 is a barrel-shaped structure with an opening on one side away from the ground and an arc-shaped bottom. This structural setting is conducive to the seeds moving to the side under the action of wind and centrifugal force, then crawling along the wall and being thrown out obliquely during rotation.

[0042] In this embodiment, the drying bin body 12-1 is provided with a discharge port 12-3 near the bottom side, and a sliding fitting part 12-4 is provided on the side away from the bottom. The sliding fitting part 12-4 is slidably fitted with the rotating support part 10-3. A discharge control part 12-5 is provided at the discharge port 12-3. The discharge control part 12-5 is connected to the discharge drive part 12-6. The discharge drive part 12-6 is used to control the discharge control part 12-5 to block or open the discharge port 12-3.

[0043] In this embodiment, two ends of the elastic member 10-9 are respectively connected to the sliding fitting portion 12-4 and the rotating support portion 10-3 to limit the sliding stroke of the drying chamber body 12-1 within a certain distance.

[0044] In this embodiment, a lubricating medium is provided on the sliding matching surfaces of the rotating support part 10-3 and the sliding matching part 12-4. The lubricating medium may be grease to ensure the lubricity of the sliding and reduce the failure rate.

[0045] In this embodiment, a dust cover is set outside the sliding matching surface of the rotating support part 10-3 and the sliding matching part 12-4. The function of the dust cover is to prevent the lubricating medium from being contaminated and becoming ineffective. Specifically, a rubber tube can be selected. After the two ends are fixed respectively, the middle has a certain degree of elasticity, which can ensure good sliding sealing when the sliding matching part 12-4 moves.

[0046] Working principle: The startup and operation process is as follows: The matching servo motor drives the rotating shaft 2 to rotate through the coupling, the rotating rotating shaft 2 drives the first pulley 3-1 to rotate, the first pulley 3-1 drives the second pulley 3-2 to rotate through the transmission belt 3-3, the second pulley 3-2 drives the connecting shaft 4-3 to rotate, the rotating shaft 2 drives the rotating part 5-1 to rotate, the rotating rotating part 5-1 drives the pushing plate 5-2 to rotate inside the seed coating part 1, the rotating pushing plate 5-2 scoops up the seeds in the coating agent through the shielding part 5-4 and supports them on the pushing plate 5-2, the leakage part 5-3 on the pushing plate 5-2 leaks the excess coating agent back into the original coating agent, and at the same time the rotating connecting The connecting shaft 4-3 drives the spiral push plate 4-4 to rotate, and the rotating spiral push plate 4-4 pushes the seeds to be coated to the two push plates 5-2 without seeds after the discharge part 6, and follows the push plate 5-2 to rotate into the coating agent for coating. The rotating rotating part 5-1 drives the impact arc groove 7-4 to rotate, and the impact arc groove 7-4 squeezes the impact column 7-3 to move into the storage groove 7-1 by raising the inclined surface block 7-5 and compresses the first spring 7-2. When the impact column 7-3 rotates from one storage groove 7-1 to another adjacent storage groove 7-1, the compressed first spring 7- 2 pushes the impact column 7-3 to impact the rotating part 5-1, thereby causing the rotating part 5-1 to vibrate. The vibrating rotating part 5-1 drives the pushing plate 5-2 to vibrate together, so that the excess coating agent of the coated seeds on the pushing plate 5-2 is shaken off. When the pushing plate 5-2 containing the coated seeds rotates to a vertical horizontal plane, the coated seeds on the current pushing plate 5-2 fall on the back of the previous adjacent pushing plate 5-2. The pushing plate 5-2 continues to rotate. When the pushing plate 5-2 containing the coated seeds on the back rotates to the discharge part 6 position, the coated seeds on the back of the pushing plate 5-2 will be discharged from the discharge part 6, and the rotating part 5-1 The direction of rotation allows the coated seeds on the push plate 5-2 to be discharged after going around most of the circle, which can remove excess coating agent on the coated seeds as much as possible, and avoid waste of coating agent after the seeds are completely coated with the coating agent. When the coating agent is less than the predetermined amount, the sensor drives the solenoid valve 8 to open so that the coating agent is added to the seed coating part 1. The excess coating agent inside the seed coating part 1 can be discharged through the drain valve 9, and water can also be added to the seed coating part 1 through the solenoid valve 8 to clean the inside of the seed coating part 1. The coated seeds are discharged to the drying bin body 12-1 through the discharge part 6 for subsequent drying.

[0047] During drying, the running motor 10-1 drives the reducer 10-2 to operate, thereby driving the rotating support part 10-3 to rotate, the rotating support part 10-3 rotates to drive the sliding matching part 12-4 to rotate, and the sliding matching part 12-4 rotates to drive the drying bin body 12-1 to rotate. The seeds inside the drying bin body 12-1 will move synchronously due to the centrifugal force, and the heat source part 10-6 and the air outlet part 10-5 will operate synchronously. The air outlet part 10-5 will emit gas, and the air duct 10- When all the gases coming out of the air duct 10-4 are collected in the heat collecting part 10-7 and blown out from the opening end of the heat collecting part 10-7 after heat radiation, the gases in the ejection part 10-8 are ejected through the ejection effect, thereby obtaining a larger air volume, further strengthening the movement trend of the seeds toward the circumference, so that under the action of centrifugal force and wind and due to the rotation of the drying chamber body 12-1, the seeds form an oblique throwing effect after crawling along the circumferential wall, thereby increasing the relative movement with the gas.

[0048] Some seeds will move upward to the height of the redirecting material distribution part 12-2. When the redirecting material distribution part 12-2 rotates with the drying bin body 12-1, the lower arc surface faces the seeds, so that the seeds can move downward along the inclined surface, thereby ensuring that the seeds return to the bottom of the drying bin body 12-1 and continue to participate in the movement. In this process, the movement trend of the seeds is affected by multiple forces, which can strengthen the relative movement between the seeds in the disordered movement, thereby reducing the adhesion rate between the seeds. At the same time, due to the amplitude of the up and down movement of the seeds, the drying bin body 12-1 will vibrate under the action of the gravity and movement trend of the seeds and the elastic force provided by the elastic member 10-9 as a spring during the rotation, thereby further improving the relative movement of the seeds and reducing the phenomenon of seed adhesion. At the same time, the movement of wind between the seeds with gaps can achieve a better drying effect.

[0049] After the wind flows upward, it will move to the inlet end area of ​​the air duct 10-4, forming a circulating wind field such as Fig.21 As shown by the arrows, the heat can be further clustered to reduce heat loss and power consumption, which helps to improve economy.
