Abstract

A discharge apparatus for discharging materials from a container onto a field, the apparatus comprising a power discharge device disposed adjacent to a discharge outlet defined by the container, the arrangement being such that when the apparatus is being used to spread the materials onto the field, the materials move from the container through the outlet towards the discharge device. A motor is drivingly connected to the discharge device for rotating the discharge device. A power sensor senses the power used by the motor and a control controls the rate at which the materials are spread. A data storage device associated with the power sensor and the control regulates the control. The arrangement is such that the data storage device dependent on the power sensor regulates the control for controlling the rate at which the materials are discharged so that when the container is moved across the field, the materials are discharged onto the field at a varying rate in order to optimize usage of the materials.

Claims

1. A discharge apparatus for discharging materials from a container onto an open area such as a field, the apparatus comprising:

a power discharge means disposed adjacent to a discharge outlet defined by the container, the arrangement being such that when the apparatus is being used to spread the materials onto the open area such as a field, the materials move from the container through said outlet towards said discharge means;

power means drivingly connected to said discharge means for rotating said discharge means;

a power sensor for sensing the torque and a rate of rotation of the discharge means for determining the power used by said discharge means; and

a control responsive to said power sensor for variably controlling a rate at which the materials are discharged from said discharge means.

2. A discharge apparatus for discharging materials from a container onto an open area such as a field, the apparatus comprising:

a power discharge means disposed adjacent to a discharge outlet defined by the container, the arrangement being such that when the apparatus is being used to spread the materials onto the open area such as a field, the materials move from the container through said outlet towards said discharge means;

power means drivingly connected to said discharge means for rotating said discharge means;

a power sensor for sensing the power used by said discharge means;

a control responsive to said power sensor for variably controlling a rate at which the materials are discharged from said discharge means;

said discharge means including;

a housing defining an inlet port and a discharge port, such that in use of the apparatus, the materials flow from said inlet port towards said discharge port;

a rotatable axle disposed within said housing and extending across the discharging materials, said axle being drivingly connected to said power means; and

hammer means secured to said axle such that when said axle rotates, said hammer means rotate within said housing for imparting kinetic energy to the materials for spreading the materials onto the field.

3. A discharge apparatus as set forth in claim 2 further including:

a data storage device associated with said power sensor and said control for regulating said control, the arrangement being such that said data storage device dependent on said power sensor regulates said control for controlling the rate at which the materials are discharged so that when the container is moved across the field, the materials are discharged onto the field at a varying rate in order to control usage of the materials.

4. A discharge apparatus as set forth in claim 3 wherein said data storage device is

a data storing device for storing data corresponding to information received from a survey of the field.

5. A discharge apparatus as set forth in claim 4, wherein said survey includes:

a combined global positioning system and soil analysis.

6. A discharge apparatus as set forth in claim 2 wherein said housing is of generally cylindrical configuration, said inlet port being connected to said outlet of the container.

7. A discharge apparatus as set forth in claim 2 wherein said rotatable axle is bearingly supported by said housing, said axle being disposed horizontally.

8. A discharge apparatus as set forth in claim 2 wherein said rotatable axle is bearingly supported by said housing, said axle being disposed vertically.

9. A discharge apparatus as set forth in claim 2 wherein said hammer means includes:

a portion rigidly secured to said axle;

a hammer portion pivotally secured to said portion so that in use of the apparatus, when said axle is rotating, said hammer portion extends generally radially away from said axle towards said housing such that said rotating hammer portion imparts said kinetic energy to the materials.

10. A discharge apparatus as set forth in claim 2 wherein said discharge means further includes:

a door movably disposed adjacent to said discharge outlet and said inlet port;

moving means connected to said door for controllably moving said door between an open and a closed disposition thereof.

11. A discharge apparatus as set forth in claim 10 wherein said control includes:

means for controlling said moving means for adjusting said disposition of said door.

12. A discharge apparatus as set forth in claim 2 wherein said power means is a hydraulic motor.

13. A discharge apparatus as set forth in claim 2 wherein said power means is an electric motor.

14. A discharge apparatus as set forth in claim 2 wherein said power means is an internal combustion motor.

15. A discharge apparatus as set forth in claim 2 wherein said control includes:

a power control for controlling power supplied by said power means.

16. A discharge apparatus as set forth in claim 2 wherein said control includes:

a speed control for controlling the speed of said discharge means.

17. A discharge apparatus as set forth in claim 2 wherein said control includes:

a ground speed control for controlling a ground speed of the apparatus.
