DEVICE FOR PRE-SOWING TREATMENT OF SEEDS IN FIELD Russian patent published in 2024 - IPC A01C1/06 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for pre-sowing treatment of seeds, mainly in field conditions, with liquid chemical and biological preparations for protecting seeds from pests and diseases, as well as plant growth stimulation. Device for pre-sowing treatment of seeds in the field with liquid preparations includes vertically installed external and internal hollow cylinders. Coaxially above them there is a loading hopper located concentrically with the external cylinder with formation of an annular cylindrical channel. Distribution cone is located coaxially above inner cylinder. Unloading funnel is located concentrically with cylinders. Coaxially with cylinders is also installed sprayer with possibility of vertical movement. Lower part of the hopper is made with a feed cone, under which an element for reducing the flow rate of seeds is installed inside on the external cylinder and an additional element is installed with a gap coaxially with it to increase the flow of seeds. Each of these elements is made in the form of a plate made with formation of a ring with a smaller and larger base, the smaller base facing downwards. Additional element is fixed on vertical rods on the inner cylinder, which is rigidly connected to radial flexible rods, the ends of which are connected to the outer cylinder. Besides, the sprayer is made in the form of a centrifugal disc. Under the distributing cone coaxially with it on radial flexible rods there is an imbalance vibrator with a motor coupled with a drive motor of the spreading centrifugal disc.

EFFECT: use of the invention will make it possible to improve the quality of seeds treatment by increasing the uniformity of coating seeds with sprayed drops by increasing the uniformity of the seed layer in the annular cylindrical channel, as well as increasing monodispersity and expansion of spray cone and imparting vibrations to the spreading centrifugal disc.
