Abstract

The invention relates to devices for spreading liquid manure, wherein a liquid manure sensor (8) determines the constituents of the liquid manure (G) to be spread and an evaluating unit (10) compares the determined values with predefined constituent data. The quantity of liquid manure (G) to be spread per area unit is calculated based on the result of the comparison. According to the result of the comparison an adjustable valve (6) actuates a distributor device (7) accordingly, by means of which the calculated quantity of liquid manure (G) is spread onto the field.

Claims

1. A device for optimizing the application amount of constituents contained in liquid manure onto ground to be fertilized, comprising:

a liquid manure tank vehicle,

a sensor adapted to analyze the constituents of the liquid manure to be applied,

an evaluating device adapted to compare data obtained analytically by the sensor with predefined constituent data,

an adjustable device adapted to vary an amount of liquid manure to be applied per unit area, the adjustable device connected to the evaluating device by a connection such that the adjustable device receives via the connection comparison data from the evaluating device,

a distributor device, wherein the adjustable device is connected to the distributor device and regulates the distributor device, such that the amount of liquid manure to be applied per unit area can be adjusted, and

a decanting line system for decanting the liquid manure from a reservoir into the liquid manure tank vehicle,

wherein the sensor is arranged in the decanting line system, such that the sensor is separated from the liquid manure tank vehicle, wherein the evaluating device and the adjustable device are arranged in or on the liquid manure tank vehicle, wherein the sensor and the evaluating device are adapted to communicate with each other by means of a temporary data connection when the liquid manure is decanted from the reservoir into the liquid manure tank via the decanting line system, and wherein the adjustable device is adapted to regulate the distributor device based on the data obtained by the sensor after the temporary data connection between the sensor and the evaluating device has been disconnected.

2. The device according to claim 1, comprising a pump for facilitating removal of the liquid manure from the reservoir.

3. The device according to claim 1, wherein a vacuum is provided to remove the liquid manure from the reservoir and to facilitate flow of the liquid manure into the liquid manure tank vehicle.

4. The device according to claim 1, comprising a mobile pump to decant the liquid manure into the liquid manure tank vehicle.

5. The device according to claim 4, wherein a mobile pump station is provided for decanting the liquid manure into the liquid manure tank vehicle.

6. The device according to claim 1, wherein the data regarding the amount of nitrogen and nitrogen-containing compounds obtained analytically by the sensor is transmitted via a connection line or wirelessly to the evaluating device.

7. The device according to claim 1, wherein the connection between the evaluating device and the adjustable device is in the form of a connection line or a wireless connection.

8. The device according to claim 6, wherein the connection line is an electrical or optical data line.

9. The device according to claim 6, wherein the wireless connection can be made via mobile phone, data radio, infrared, or wireless data communication device utilizing a wireless data communication standard.

10. The device according to claim 7, wherein the connection line is an electrical or optical data line.

11. The device according to claim 1, wherein the sensor is an optical sensor.

12. The device according to claim 11, wherein the optical sensor is adapted to subject the liquid manure to a spectral analysis.

13. The device according to claim 7, wherein the wireless connection can be made via mobile phone, data radio, infrared, or wireless data communication device utilizing a wireless data communication standard.

14. The device according to claim 1, wherein the sensor is adapted to analyze an amount of nitrogen and nitrogen-containing compounds in the liquid manure to be applied.

15. The device according to claim 1, wherein the distributor device is arranged in or on the liquid manure tank vehicle.

16. The device according to claim 1, wherein the distributor device is arranged in or on a separate distributor vehicle, the separate distributor vehicle being connected to the liquid manure tank vehicle by means of a line system during distribution of the liquid manure.
