Description

Technical Field

[0001] The utility model belongs to the technical field of seed coating, and in particular relates to a seed coating machine with uniform coating. Background Art

[0002] Seed coating machine is a machine that coats the surface of selected seeds with coating agent to make them into pellets. After sowing, the seeds coated with coating agent can quickly absorb water and swell. With the gradual development of the embryo in the seed and the continuous growth of the seedling, the coating agent will slowly release the various effective ingredients contained in it, which will be gradually absorbed into the body by the seed seedling, so as to achieve the purpose of preventing and controlling diseases and insect pests in the seedling stage, promoting growth and development, and increasing crop yields.

[0003] Existing seed coating machines usually use a method of mixing seeds and coating agents to coat the seeds. Since the coating agent is put into the silo at one time, it is not evenly distributed in the silo. Even if the seeds are stirred for a long time, it is difficult to ensure that the seeds are evenly coated with the coating agent, resulting in poor seed coating quality. At the same time, long-term stirring can easily cause seed damage. Utility Model Content

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model comprises a cylinder, wherein the inner bottom wall of the cylinder is connected to a coating chamber, wherein the coating chamber comprises a bottom plate, wherein an annular enclosure is arranged at the edge of the bottom plate, wherein a transmission shaft is arranged at the center of the bottom plate, wherein a motor mounting seat is arranged at the lower surface of the bottom plate, wherein a driving motor is arranged on the motor mounting seat, wherein the output end of the driving motor is connected to the transmission shaft in a transmission manner, wherein a connecting sleeve is arranged on the transmission shaft, wherein a plurality of mixing plates are connected to the peripheral surface of the connecting sleeve, wherein the mixing plates are evenly distributed in an array along the circumference of the connecting sleeve, and wherein the bottom plate A discharge port is provided on the top, and a discharge baffle is detachably installed on the lower surface of the bottom plate below the discharge port. A storage barrel is provided on the top of the cylinder body, and a coating agent is provided in the storage barrel.

One end of the liquid inlet pipe is connected to the coating agent spraying mechanism, and the other end of the liquid inlet pipe extends into the storage barrel. The side wall of the cylinder body is connected to a feed trough.

[0013] With this arrangement, seeds to be coated are placed in the feed trough, the seeds enter the barrel and fall into the coating chamber below, the drive motor and the transmission shaft are driven to rotate, thereby driving the connecting sleeve on the transmission shaft to rotate, and the connecting sleeve drives the mixing plate to rotate to stir the seeds. At the same time, the coating agent is added to the storage barrel, the coating agent enters the liquid outlet pipe and is sprayed onto the seeds through the coating agent spraying mechanism, and is fully mixed with the seeds to achieve seed coating. After the coating is completed, the discharge baffle is opened, the drive motor is started to maintain a low speed, and the mixing plate is slowly rotated, and the coated seeds can be discharged from the discharge port to complete the discharge. Since the mixing plates are evenly distributed in an array along the circumference of the connecting sleeve, when the seeds are stirred, the seeds will gradually be evenly distributed in the space formed by the adjacent mixing plates, the bottom plate and the annular enclosure. At the same time, multiple coating agent spraying mechanisms are also correspondingly distributed in an annular array, and the coating agent can be sprayed evenly in an annular shape in the coating chamber, so that the coating agent can be more easily and evenly coated on the seeds, which not only improves the seed coating efficiency, but also makes the seeds fully coated with the coating agent, thereby improving the seed coating quality, and effectively solves the problem of insufficient coating of seeds with coating agents during coating by existing coating machines, resulting in poor seed coating quality.

When the mixing plate stirs the seeds, the coating agent can be sprayed out in multiple times, and the spraying amount of the coating agent in a single time can be gradually reduced through the flow regulator as the stirring time increases. While the seeds are fully coated with the coating agent, the coating agent can also be prevented from being sprayed excessively, thereby reducing the waste of raw materials.

[0015] 3. In the present invention, the mixing plate is an arc-shaped plate. With this arrangement, the arc-shaped plate can increase the contact area with the seeds, improve the stirring efficiency of the seeds, make the seeds easier to be fully mixed with the coating agent, and ensure that the coating agent is evenly coated on the seeds.
