Abstract

An agricultural implement that includes a slotting mechanism and a slotting actuator is provided. The slotting mechanism is for cutting slots in a drip line in real time in conjunction with ground placement of the drip line. The slotting actuator is for actuating the slotting mechanism. The actuating is controlled by a computer following a slot spacing in a drip line prescription for a field in which a drip line is being placed.

Claims

1. A drip line placement system comprising:

a computer for interpreting a drip line prescription for a field in which a drip line is being placed, wherein the drip line prescription relates to slot spacing for the drip line and position in the field;

a global navigation satellite system (GNSS) receiver coupled with the computer and configured for determining a position of the drip line placement system; and

an agricultural implement communicatively coupled with the computer, the agricultural implement comprising;

two or more spindles for each holding respective spools of drip line;

a tool bar supporting the two or more spindles, wherein the tool bar facilitates adjusting placement of the two or more spindles for each holding respective spools of drip line;

a slotting mechanism for cutting slots in the drip line in real time in conjunction with ground placement of the drip line as determined based on the position of the drip line placement system determined using the GNSS receiver; and

a slotting actuator for actuating the slotting mechanism, wherein actuation of the slotting actuator is controlled by the computer following a slot spacing prescribed for the position of the drip line placement system in the drip line prescription.

2. A drip line placement system of claim 1, wherein the slotting mechanism is an electrically controlled slotting mechanism and wherein the drip line placement system further comprises:

a shank for creating an opening in a ground of the field for burying the drip line after the slots are cut by the slotting mechanism.

3. A drip line placement system of claim 1, wherein the slotting actuator is attached to the tool bar.

4. A drip line placement system of claim 1, wherein the tool bar facilitates spacing the two or more spindles further apart or closer together.

5. A method for placing a drip line in a field, the method comprising:

determining global navigation satellite system (GNSS) positions of an agricultural vehicle based on data received from a GNSS receiver associated with the agricultural vehicle as the agricultural vehicle moves through the field;

calculating, performed by a hardware processor of a computer, a drip line prescription for the field, wherein the drip line prescription relates to slot spacing for the drip line and position in the field;

interpreting the drip line prescription to identify slotting mechanism positions based on the GNSS positions and a model of the agricultural vehicle coupled with an agricultural implement, wherein the agricultural implement comprises;

two or more spindles for each holding respective spools of drip line;

a tool bar supporting the two or more spindles, wherein the tool bar facilitates adjusting placement of the two or more spindles for each holding respective spools of drip line;

a slotting mechanism for cutting slots in the drip line in real time in conjunction with ground placement of the drip line as determined based on the GNSS positions; and

a slotting actuator for actuating the slotting mechanism, wherein actuation of the slotting actuator follows a slot spacing prescribed for the GNSS positions in the drip line prescription;

creating slots in the drip line in real time according to the drip line prescription based on positions of the agricultural vehicle as determined using the GNSS receiver; and

placing the drip line in the field.

6. The method as recited by claim 5, wherein the method further comprises:

performing the interpreting and the creating repeatedly until all slots specified by the drip line prescription have been created.

7. The method as recited by claim 5, wherein the method further comprises:

varying at least one characteristic of the slots being created based on a variable rate drip line prescription, wherein the at least one characteristic is selected from a group consisting of slot size and distance between adjacent slots of the drip line.

8. The method as recited by claim 5, wherein the agricultural implement includes a slotting mechanism for creating slots in the drip line and a slotting actuator that controls the slotting mechanism and wherein the method further comprises:

transmitting a command from the computer to the slotting actuator in response to the drip line prescription specifying the slotting mechanism positions.

9. The method as recited by claim 8, wherein the slotting actuator actuates the slotting mechanism to create a slot in the drip line upon the slotting actuator receiving the command.

10. The method as recited by claim 8, wherein the method further comprises:

unspooling the drip line from a spool;

guiding the drip line from the spool with respect to the slotting mechanism; and

creating the slots in the drip line in real time by actuating the slotting mechanism based on the drip line prescription as the drip line is being unspooled.

11. The method as recited by claim 5, wherein placing the drip line in the field includes:

creating an opening in a ground of the field; and

placing the drip line in the opening.
