Abstract

A spreader configured for dispersing a non-grain crop material onto a field. The spreader includes a floor panel having a distal end, a pair of side deflectors pivotally connected to the floor panel, and a table slideably connected to the floor panel and slideable between a retracted position and an extended position in which at least a portion of the table is extended past the distal end of the floor panel.

First claim

What is claimed is:

1. A spreader for an agricultural vehicle, comprising:
a floor panel having a distal end;
a pair of side deflectors pivotally connected to the floor panel; and
a table slideably connected to the floor panel and slideable between a retracted position and an extended position in which at least a portion of the table is extended past the distal end of the floor panel,
wherein the table and side deflectors are moveably linked such that as the table slides into the extended position the side deflectors correspondingly narrow, and as the table slides into the retracted position the side deflectors correspondingly widen.

2. The spreader of claim 1 , further comprising a pair of linkages respectively linking the table to each side deflector so that a motion of the table automatically adjusts the side deflectors.

3. The spreader of claim 2 , further comprising a pair of support members, each support member is connected to a respective side deflector and a respective linkage.

4. The spreader of claim 1 , wherein each side deflector comprises a protrusion and the table comprises at least two grooves for respectively receiving a respective protrusion of each side deflector, and as the table slides between the retracted and extended positions a motion of the table correspondingly moves each side deflector.

5. The spreader of claim 1 , further comprising an actuator attached to the floor panel and the table, and the actuator is configured for retracting and extending the table.

6. The spreader of claim 1 , further comprising at least one rail slideably connecting the table to the floor panel, and the at least one rail is fixedly attached to the table and slideably attached to the floor panel.

7. The spreader of claim 6 , wherein the floor panel comprises an underside and at least one coupling member attached to the underside, and the at least one coupling member slideably receives and guides the at least one rail.

8. The spreader of claim 7 , wherein the at least one rail comprises a pair of rails and the at least one coupling member comprises at least two coupling members for slideably receiving each respective rail.

9. An agricultural vehicle, comprising:
a chassis; and
a spreader connected to the chassis and configured for dispersing a non-grain crop material onto a field, the spreader comprising:
a floor panel having a distal end;
a pair of side deflectors pivotally connected to the floor panel; and
a table slideably connected to the floor panel and slideable between a retracted position and an extended position in which at least a portion of the table is extended past the distal end of the floor panel,
wherein the table and side deflectors are moveably linked such that as the table slides into the extended position the side deflectors correspondingly narrow, and as the table slides into the retracted position the side deflectors correspondingly widen.

10. The agricultural vehicle of claim 9 , wherein the spreader further comprises a pair of linkages respectively linking the table to each side deflector so that a motion of the table automatically adjusts the side deflectors.

11. The agricultural vehicle of claim 10 , wherein the spreader further comprises a pair of support members, each support member is connected to a respective side deflector and a respective linkage.

12. The agricultural vehicle of claim 9 , wherein each side deflector comprises a protrusion and the table comprises at least two grooves for respectively receiving a respective protrusion of each side deflector, and as the table slides between the retracted and extended positions a motion of the table correspondingly moves each side deflector.

13. The agricultural vehicle of claim 9 , wherein the spreader further comprises an actuator attached to the floor panel and the table, and the actuator is configured for retracting and extending the table.

14. The agricultural vehicle of claim 9 , further comprising at least one rail slideably connecting the table to the floor panel, and the at least one rail is fixedly attached to the table and slideably attached to the floor panel.

15. The agricultural vehicle of claim 14 , wherein the floor panel comprises an underside and at least one coupling member attached to the underside, and the at least one coupling member slideably receives and guides the at least one rail.

16. The agricultural vehicle of claim 15 , wherein the at least one rail comprises a pair of rails and the at least one coupling member comprises at least two coupling members for slideably receiving each respective rail.

17. A method for dispersing a non-grain crop material, comprising the steps of:
providing a spreader configured for dispersing the non-grain crop material onto a field, the spreader comprises a floor panel having a distal end, a pair of side deflectors pivotally connected to the floor panel, and a table slideably connected to the floor panel and moveably linked to the side deflectors so that a motion of the table automatically adjusts the side deflectors, and the table is slideable between a retracted position and an extended position; and
one of:
sliding the table outwardly into the extended position, which correspondingly narrows the side deflectors; and
sliding the table inwardly into the retracted position, which correspondingly widens the side deflectors.

18. The method of claim 17 , wherein the spreader further comprises a pair of linkages and a pair of support members, and each linkage connects the table to a respective side deflector, and each support member respectively connects each linkage to each side deflector.
