Description

Technical Field

[0001] The present invention relates to a fully automatic seed coating device, belonging to the technical field of coating devices. Background Art

[0002] Seed coating is to attach and solidify a coating agent containing one or more components of insecticides, fungicides, and plant nutrients on the seed surface through film coating or pelletizing processing of the seeds, which can play the role of precise drug use, early prevention, labor-saving and labor-saving control of seed-borne and soil-borne diseases and pests. Pelletizing processing can also create favorable conditions for the mechanized precision sowing of small seeds.

[0003] There are various seed coating devices in the prior art. For example, the vertical rotation spray type seed coating machine disclosed in the patent number CN200710131160.X, the automatic seed coating machine disclosed in the patent number CN201711461924.1, etc. Although the existing seed coating devices can complete the coating process of the seeds, there are the following deficiencies in the specific use process:

[0040] The gate plate 16 between the first conical cylinder 2 and the second conical cylinder 3 separates the coating chamber 8 and the drying chamber 9. The gate plate 16 is used to control the coated seeds to enter the drying chamber 9 from the coating chamber 8.

[0041] The shutter 16 between the third conical cylinder 4 and the fourth conical cylinder 5 separates the drying chamber 9 and the screening chamber 10, and the shutter 16 is used to control the entry of the dried coated seeds from the drying chamber 9 into the screening chamber 10.

[0042] The said shutter 16 has a heat insulation function to prevent the heat in the drying chamber 9 from entering the coating chamber 8 or the screening chamber 10.

[0043] Two symmetrically arranged screens 17 are installed between the fifth conical cylinder 6 and the sixth conical cylinder 7. The bottom of each screen 17 is fixedly connected with a grid plate 18 that moves synchronously with it. The grid plate 18 supports the screen 17, and the grid plates 18 are respectively driven by cylinders. After the grid plates 18 are opened, the screened seeds will fall onto the conveyor belt 19.
