[0021] Referring to the accompanying drawings, this embodiment is described, a seed coating device 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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 .

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 first pulley 3-1 and the second pulley 3-2 are connected through the transmission belt 3-3. 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.

[0030] 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.

[0031] 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, and the leakage part 5-3 on the pushing plate 5-2 leaks the excess coating agent back to the original coating agent At the same time, the rotating connecting shaft 4-3 drives the spiral push plate 4-4 to rotate. 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. 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 first spring 7-2 compressed inside the groove 7-1 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. 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 pushing plate 5-2 The coated seeds on the back will be discharged from the discharge part 6. The rotation direction of the rotating part 5-1 makes the coated seeds on the push plate 5-2 be discharged after going around most of the circle. This can remove the excess coating agent on the coated seeds as much as possible, and avoid the 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 inside of 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 inside of the seed coating part 1 through the solenoid valve 8 to clean the inside of the seed coating part 1.
