The system of applying preservatives

The system for the application of preserving agents of SVK (hereinafter referred to as the system) is intended for controlling the process of processing stalked forages

with preservative solutions in order to preserve their nutritional value and preserve the feed during storage.

The CRS system is installed on self-propelled harvesters: John Deere, Jaguar, Claas, Rostselmash, Gomselmash, Don.

System components: control unit (BU), display unit (BI), filter, flow sensor (flowmeter), electric pump, atomizer unit, mini valve, mass availability sensor, connecting hoses, bundles, canister assembly.

The principle of the system is as follows: the liquid from the canister, through a suction filter, is fed by a pump under pressure to the spray unit mounted on the silo pipeline and enters the ground green mass. As the liquid passes through the mass sensor, the amount of liquid that has passed through a unit of time is fixed. The signal from the sensor is fed to the BU, processed by it, then the information is displayed on the BI, which is installed in the cab of the combine and serves to display information coming from the BU and controlling the technological modes of operation of the system.

3 The system monitors the following parameters and mechanisms:

- operative change of the volume of liquid supply (preservative);

- pump activation;

- the presence of green mass in the silo.

4 Deviation of supply of working fluid from the established norm ± 5%.

5 The system provides a choice of operating mode - automatic or manual.

6 The system provides for the possibility of accumulating and outputting statistical (emergency) information.

7 The system is powered by the onboard network of a combine harvester with a nominal voltage of 24 V.
