Technical Field

[0001] The utility model relates to the technical field of seed coating, in particular to a seed coating device. Background Art

[0002] Seed coating, also known as seed coating, is to use a coating agent to pre-wrap the seeds. After sowing, as the embryo in the seeds gradually develops and the seedlings continue to grow, the effective ingredients in the coating agent are slowly released and then gradually absorbed into the body by the seed seedlings, thereby achieving the purpose of preventing and controlling diseases and insect pests in the seedling stage, promoting growth and development, and increasing crop yields;

[0003] In the prior art, in order to improve the efficiency of seed coating, a coating device is usually required, such as the one disclosed in the patent with the publication number CN217773961U. Specifically, an inclined filter plate is arranged in the chassis to make the seeds roll on the filter plate, and then the seeds can be fully coated after being sprayed by the spray device on the top;

[0004] However, although the inclined filter plate can achieve the rolling of seeds, the uniformity of the coating cannot be controlled, which easily leads to uneven coating of single seeds and adhesion of multiple seeds.

[0005] Based on the above description, there is an urgent need for a seed coating device that can reduce seed clumping during the coating process. Utility Model Content

[0010] Preferably, the partition is provided with an arc-shaped convex strip extending toward the inner side wall of the tank body.

[0011] Preferably, a pair of adjacent partition plates are connected to the outer side wall of the connecting cylinder at an acute angle.

[0012] Preferably, the spraying assembly includes a storage tank and a plurality of atomizing nozzles; the plurality of atomizing nozzles are arranged in a ring at one end of the storage tank close to the inner cavity of the tank body; the atomizing nozzles are communicated with the storage tank.

[0025] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: A seed coating device, applicable to the situation of atomizing and spraying film for seeds.

[0026] Specifically, as Figure 1 and Figure 2 shown, a seed coating device includes a spray assembly 1, a rotating assembly 2 and a partition assembly 3; the rotating assembly 2 includes a tank body 21 and a rotating shaft 22; the rotating shaft 22 penetrates through the tank body 21; one end of the partition assembly 3 is connected to the rotating shaft 22; the other end of the partition assembly 3 extends towards the inner side wall of the tank body 21; the spray assembly 1 is arranged at the inlet end of the tank body 21 and is connected to the end of the rotating shaft 22 that penetrates out of the tank body 21.

[0027] In this embodiment, the tank body 21 is divided into multiple coating chambers by the partition assembly 3, and further, the partition assembly 3 is rotated by the rotating shaft 22, so that while the seeds in each coating chamber roll in the chamber, the rotating partition assembly 3 also plays a role in stirring. Thus, not only is it convenient for the spray assembly 1 to spray into each coating chamber, but also the seeds can be evenly coated and the agglomeration of the coated seeds can be avoided.

[0028] In this embodiment, the tank body 21 can be supported and fixed at both ends by a triangular support base commonly used in the prior art. The spray assembly 1 is connected to one end of the tank body 21. The rotating shaft 22 is driven by a servo motor and is supported and fixed at both ends of the tank body 21 through a machine base, thereby forming a state where the tank body 21 and the spray assembly 1 are relatively stationary and the grouping assembly 3 rotates relatively; in addition, the tank body 21, the spray assembly 1 and the partition assembly 3 can also be set to a state of integral rotation. At this time, the two ends of the rotating shaft 22 are directly connected to the top of the support seat provided with a servo motor.

[0029] Specifically, as Figure 1 and Figure 2 shown, the partition assembly 3 includes a connecting cylinder 31 and multiple partition boards 32; the connecting cylinder 31 is sleeved outside the rotating shaft 22; the multiple partition boards 32 are arranged annularly outside the connecting cylinder 31 and extend towards the inner side wall of the tank body 21.

[0030] In this embodiment, multiple partitions 32 are provided to facilitate the division of the inner cavity of the tank body 21 into multiple coating chambers, wherein the partitions 32 have a certain length, and the distance between two adjacent partitions is small, and a pair of adjacent partitions 32 are connected to the outer wall of the connecting tube 31 at an acute angle, thereby forming a narrow and long coating chamber, so that the seeds in each coating chamber are not easy to clump during the coating process. Furthermore, the partition is provided with an arc-shaped convex strip extending toward the inner wall of the tank body 21; the arc-shaped convex strip can be in contact with the inner wall of the tank body 21 or leave a small distance to avoid wear during rotation.

[0032] In this embodiment, the storage box 11 is connected to one end of the tank body 21 via a flange 4; the storage box 11 is provided with a feed pipe joint, and the coating agent can be added continuously by opening the pipe valve of the pipe joint and connecting the feed pipe.

[0033] Specifically, Figure 1 and Figure 4 As shown, the rotating shaft 22 passes through the liquid storage tank and is connected to an end of the liquid storage tank away from the atomizing nozzle 12 through the sliding assembly 5.

[0034] In this embodiment, the sliding assembly 5 includes a ball sleeve and multiple balls. The ball sleeve is slidably connected to the rotating shaft 22 through multiple balls, so that after the spray assembly 1 and the tank body 21 are connected through the flange 4, they are supported by the existing triangular support base and are relatively stationary, while the rotating shaft 22 drives the partition assembly 3 inside the tank body 21 to rotate relatively; seeds can be put in through the movable door 23 hinged on the side wall of the tank body 21, or they can be put in from the end opening of the tank body 21 before installing the spray assembly 1.

[0035] Specifically, Figure 1 As shown, one end of the tank body 21 away from the atomization assembly is connected to the negative pressure assembly 6.

[0036] In this embodiment, the negative pressure component 6 includes an air pump and an air suction pipe; the air suction pump is arranged at one end of the tank body 21 away from the spray component 1, and is connected to the inner cavity of the tank body 21 through the air suction pipe. Then, in the process of coating the seeds, the coating agent is sprayed into one end of the tank body 21 through the spray component 1, and then extracted under the condition of negative pressure formed by the air suction pump at the other end, so that the atomized coating agent can pass through each coating cavity and fully and evenly coat the rolling seeds.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model.
