Description

Description of the invention

The subject of the invention is a mobile seed dressing machine for seed dressing directly before sowing, mounted on a tractor.

In the Polish patent description PL 169 112 a seed treating machine is presented, equipped with a disc sprayer placed in the sprinkling chamber. The body has a partition divided into two chambers, the upper one is the spraying chamber and the lower one is the mixing chamber. A spiral ribbon conveyor is embedded in the mixing chamber. Under the mixing chamber, there is a housing mounted in the housing, which is connected to the mixing chamber through the discharge opening, on the one hand, and with the bagging machine on the other hand.

The Polish patent description PL170465 describes a method and a device for seed treatment. The apparatus comprises a foam generator providing a first foaming chamber provided with a gas injection port and an opening for introducing a composition containing a foaming agent. The first chamber passes into a second foam compression and structuring chamber and ends with a foam outlet nozzle. The container is equipped with a system for mixing seeds and a system for introducing a composition containing a plant protection product.

The Polish patent description PL 188730 describes a seed treating machine equipped with a seed hopper, a screw conveyor and a treatment agent tank. The treatment agent dosing unit is equipped with a pneumatic valve connected to the seed hopper with a flexible conduit. The dosing unit is fed with the dressing agent by gravity.

In the Polish patent description PL 225841 a seed dressing machine adapted for seed dressing with liquid or foam dressing is presented. The dressing machine has a base on which a pressure tank with mortar is mounted and a seed hopper with a charging hopper, inside which there are nozzles for spraying the mortar and a screw conveyor driven by an electric motor. The nozzles spraying the mortar are directed towards each other in opposite directions. The screw conveyor and the blade propeller are mounted on a common shaft.

The aim of the invention is to construct a mobile seed dressing machine used for seed dressing directly before sowing in the field, powered by the tractor's pneumatic system, eliminating contamination with the treatment agent on objects in the area of the farm buildings.

A mobile seed dressing machine according to the invention, mounted on a tractor, equipped with a base on which a pressure tank and a seed hopper are placed, with a treatment chamber at the bottom of which there is an inlet of the auger, characterized by the fact that the pressure tank of the mortar is connected with a hose to the tractor's pneumatic system quick coupler via a three-way pressure reducing valve. The pressure tank is also connected to the seed treatment chamber through a filter and dosing valve. The three-way pressure reducing valve is also connected to the worm gear by a conduit.

The mobile seed dressing machine is shown schematically in an embodiment in the accompanying drawing.

P r z k ł a d

The mobile seed treating machine has a base 1 with a suspension system 2 on which a pressure tank 10 and a seed hopper 3 with a treatment chamber 4 are seated. At the bottom of the seed treatment chamber 4 there is an inlet of a screw conveyor 5 driven by a hydraulic motor 7 from the tractor. The hydraulic motor 7 is connected by a hydraulic conduit 8 via a quick coupler 9 to the tractor. The screw conveyor 5 at the top has an outlet connected by a line 6 to the bagging machine. The pressure tank 10 for the seed treatment is provided with a filler 11 and a pressure gauge 12. The pressure tank 10 also has a safety valve 13. The quick coupler 15 of the tractor is connected by a pipe with a three-way reduction valve 16 supplying compressed air with a pneumatic line 14 to the pressure tank 10. The pressure tank 10 is connected to the through the conduit 20 with the seed treatment chamber 4, via the filter 17 and the dosing valve 18. The three-way reduction valve 16 is also connected by the conduit 21 with the worm gear 5. The mobile seed dressing machine is aggregated with the tractor by a suspension system 2. The hydraulic conduit 8 is connected to the tractor with a quick coupler 9 The pneumatic conduit 14 is connected to the tractor with a pneumatic quick coupler 15. The pressure tank 10 is supplied with air with constant pressure parameters ensuring uniform operation through a quick coupler 15, a three-way reduction valve 16 and a pneumatic conduit 14. With the aid of the tractor's hydraulic system, the hydraulic motor 7 is driven to move the screw conveyor 5. Seeds in the chamber

PL 237 576 Β1 for dressing 4 are sprayed with the mortar supplied through a conduit 20 ended with a nozzle, the amount of the applied mortar is dosed by the dosing valve 18. The seeds are mixed and transported upwards by means of a screw conveyor 5. In the screw conveyor 5, the treated seeds are dried with air introduced through a conduit 21 from of the three-way reduction valve 16. The treated seeds from the top of the screw conveyor 5 fall into the bagging machine 6.
