Abstract

A marking assembly for attachment to a vehicle for distributing a marking agent on a substantially grass-covered field to mark one or more lines in one or more predetermined areas thereof. The marking assembly includes a deck having a grass-cutting subassembly for mowing the grass and removing the cuttings thereof to provide freshly-mown grass in the predetermined area, the deck being attachable to the vehicle. The marking assembly also includes one or more nozzle subassemblies positionable downstream relative to the grass-cutting subassembly when the vehicle travels in a forward direction. The nozzle subassembly includes one or more nozzles for releasing the marking agent to mark the line on the predetermined area.

Claims

1. A marking assembly for attachment to a vehicle for distributing a marking agent on a substantially grass-covered field to mark at least one line in at least one predetermined area thereof, the marking assembly comprising:

a deck comprising a grass-cutting subassembly for mowing the grass and removing the cuttings thereof to provide freshly-mown grass in said at least one predetermined area of the field, the deck being attachable to the vehicle;

at least one nozzle subassembly mounted on the vehicle and positioned downstream relative to the grass-cutting subassembly when the vehicle travels in a forward direction, said at least one nozzle subassembly comprising at least one nozzle for releasing the marking agent to mark said at least one line on said at least one predetermined area of the field;

when attached to the vehicle, the deck being movable between a lowered position, in which the grass-cutting subassembly is positioned to cut grass on the field, and a raised position, in which the grass-cutting assembly is positioned to substantially avoid engagement thereof with the grass;

said at least one nozzle subassembly comprising a mounting bracket for attaching said at least one nozzle to the vehicle and at least one shoe for directing the marking agent, upon its release from said at least one nozzle, to mark said at least one line;

the mounting bracket additionally comprising at least one member extending between proximal and distal ends thereof, said at least one member being pivotably attached to the vehicle at the proximal end thereof;

said at least one nozzle being attached to said at least one member at a first preselected distance from the proximal end; and

at least one connecting element connecting said at least one member at a second preselected distance from the proximal end.

2. A marking assembly according to claim 1 in which said at least one connecting element is adapted for adjustment of the lowered and raised positions.

3. A marking assembly according to claim 1 in which the mounting bracket is positionable in an operational position, in which said at least one nozzle is positioned substantially at a first predetermined height above the field to mark said at least one line thereon when the deck is in the lowered position.

4. A marking assembly according to claim 3 in which the mounting bracket is adapted to remain in the operational position relative to the field during upward movement of the deck.

5. A marking assembly according to claim 1 additionally comprising at least one wheel for at least partially supporting the deck above the field and lockable into a locked position for guiding the deck substantially in the forward direction.

6. A marking assembly according to claim 5 additionally comprising an alarm which, when said at least one wheel is in the locked position, is activated upon the vehicle being turned by more than a predetermined angle.

7. A marking assembly according to claim 1 additionally comprising:

a pump for providing said marking agent at a preselected rate of flow to said at least one nozzle;

a controller for controlling said pump to provide the marking agent at the preselected rate of flow; and

the controller being adapted to select the preselected rate of flow at least partly based on a rate of movement relative to the field of the marking assembly in the forward direction.

8. A marking assembly according to claim 1 additionally comprising at least two plates mounted on the vehicle and the deck respectively, said at least two plates comprising markings thereon respectively which are substantially aligned when the marking assembly is travelling in the forward direction, to facilitate steering the vehicle in the forward direction.

9. A marking assembly according to claim 1 additionally comprising a movable nozzle subassembly mounted on an arm pivotably attached to the deck at a pivot end thereof for pivoting about an axis, to release the marking agent to mark a line at least partially along an arc defined by pivoting movement of the nozzle subassembly about the axis.

10. A marking assembly according to claim 1 additionally comprising a movable nozzle subassembly positionable at a predetermined distance from said at least one nozzle subassembly, each of the movable nozzle subassembly and said at least one nozzle subassembly being adapted to mark lines respectively while the marking assembly travels in the forward direction, such that said lines are marked substantially parallel to each other.

11. A marking assembly for attachment to a marking vehicle for releasing a marking agent on a substantially grass-covered field to mark at least one line in at least one predetermined area thereof, the marking assembly comprising:

an arm pivotably attached at a pivot end thereof to the marking vehicle, the arm being adapted to pivot about an axis, the arm extending between the pivot end and a nozzle end thereof;

a movable nozzle subassembly mounted to the arm at the nozzle end, the movable nozzle subassembly comprising at least one nozzle to which the marking agent is supplied, said at least one nozzle being adapted for releasing the marking agent to mark said at least one line on said at least one predetermined area of the field; and

the movable nozzle subassembly comprising at least two shoes for directing the marking agent, upon its release from said at least one nozzle, to mark said at least one line.

12. A marking assembly according to claim 11 in which said at least one nozzle is adapted for releasing the marking agent to mark a line at least partially along an arc defined by pivoting movement of the nozzle subassembly about the axis.

13. A marking assembly according to claim 12 in which the arm is lockable to locate the movable nozzle subassembly at a predetermined position on said arc.

14. A marking assembly according to claim 12 in which said at least one movable nozzle subassembly is controllable to mark the line a preselected distance along said arc.

15. A marking vehicle for releasing a marking agent on a substantially grass-covered field to mark at least one line in at least one predetermined area thereof, the marking vehicle comprising:

a vehicle portion movable in a forward direction;

a deck comprising a grass-cutting subassembly for mowing the grass and removing the cuttings thereof to provide freshly-mown grass in said at least one predetermined area of the field, the deck being attachable to the vehicle portion; and

at least one nozzle subassembly positioned downstream relative to the grass-cutting subassembly when the vehicle portion travels in the forward direction, said at least one nozzle subassembly comprising at least one first nozzle for releasing the marking agent to mark said at least one line on said at least one predetermined area of the field;

said at least one nozzle subassembly comprising a mounting bracket for attaching said at least one first nozzle to the vehicle and at least one shoe for directing the marking agent, upon its release from said at least one first nozzle, to mark said at least one line;

a movable nozzle subassembly comprising at least one second nozzle mounted on an arm pivotably attached to the deck at a pivot end thereof for pivoting movement about an axis, adapted to release the marking agent from said at least one second nozzle to mark a line at least partially along an arc defined by pivoting movement of the movable nozzle subassembly about the axis; and

the movable nozzle subassembly comprising at least two shoes for directing the marking agent, upon its release from said at least one nozzle, to mark said at least one line.

16. A marking vehicle according to claim 15 in which the arm is lockable to locate the movable nozzle subassembly at a predetermined position on said arc.
