Extendable and retractable conveyor
An extendable and retractable conveyor includes a hopper for receiving agricultural product, and a housing having an inlet and an outlet that are separated by a fixed distance, the inlet being adjacent to the hopper for receiving the agricultural product from the hopper. The extendable and retractable conveyor also include a belt conveyor disposed within the housing for conveying the agricultural product from the inlet to the outlet, the conveyor defining a direction of conveyance; a hood connected to the outlet for deflecting the agricultural product relative to the direction of conveyance; and a movable spout that is slidably connected to a tube and disposed beneath the hood to receive the agricultural product from the hood, the movable spout being slidable in a direction parallel to the direction of conveyance to thereby extend or retract the conveyor.
1. An extendable and retractable conveyor comprising:
a hopper for receiving agricultural product;
a housing having an inlet and an outlet that are separated by a fixed distance, the inlet being adjacent to the hopper for receiving the agricultural product from the hopper;
a continuous loop conveyor disposed within the housing for conveying the agricultural product from the inlet to the outlet, the continuous loop conveyor having an upper product-conveying segment defining a direction of conveyance and a return segment beneath the upper product-conveying segment moving opposite to the direction of conveyance;
a hood connected to the outlet for deflecting the agricultural product relative to the direction of conveyance; and
a movable spout that is slidably connected to the housing and disposed beneath the hood to receive the agricultural product from the hood, the movable spout being slidable in a direction parallel to the direction of conveyance to thereby extend or retract the conveyor, and wherein the return segment passes between the movable spout and the housing.
2. The extendable and retractable conveyor of claim 1 comprising a slidable carriage to which the movable spout is mounted, the slidable carriage being configured to slide relative to the housing to move the movable spout.
3. The extendable and retractable conveyor of claim 2 comprising guide rails extending along the sides of the housing.
4. The extendable and retractable conveyor of claim 3 wherein the slidable carriage comprises sliders or rollers configured to slide or roll in the guide rails to displace the slidable carriage relative to the housing.
5. The extendable and retractable conveyor of claim 2 comprising a drive mechanism connected to the slidable carriage to displace the slidable carriage and the movable spout relative to the housing.
6. The extendable and retractable conveyor of claim 5 wherein the drive mechanism comprises a drive motor and drive track that drives the slidable carriage along the housing.
7. The extendable and retractable conveyor of claim 6 wherein the drive motor and the drive track are mounted on a top of the housing.
8. The extendable and retractable conveyor of claim 6 wherein the drive motor and the drive track are mounted on a side of the housing.
9. The extendable and retractable conveyor of claim 5 wherein the drive mechanism comprises a linear actuator that drives the slidable carriage along the housing.
10. The extendable and retractable conveyor of claim 1 wherein the movable spout comprises a forward wall slanted at a first angle and a rearward wall slanted at a second angle, wherein the first and second angles are different.
11. The extendable and retractable conveyor of claim 1 wherein the movable spout includes U-shaped channels for sliding over respective rails secured by hangers to the housing.
12. The extendable and retractable conveyor of claim 1 comprising an input shaft connectable to a PTO of a tractor and a power transmission unit for transmitting power to an output shaft that connects to a drive pulley of the continuous loop conveyor.
13. The extendable and retractable conveyor of claim 12 wherein the input shaft is parallel to a direction of conveyance.
14. The extendable and retractable conveyor of claim 2 comprising a motor to displace the slidable carriage, wherein the motor is disposed beneath the housing.
15. An extendable and retractable conveyor comprising:
a hopper for receiving agricultural product;
a housing having an inlet for receiving the agricultural product from the hopper;
a continuous loop conveyor disposed within the housing for conveying the agricultural product from the inlet to an outlet, wherein the inlet and the outlet are separated by a fixed distance;
a hood connected to the outlet; and
a movable spout suspended beneath the hood to receive the agricultural product from the hood, the movable spout being slidable to thereby extend or retract the conveyor, wherein a return segment of the continuous loop conveyor passes between the movable spout and the housing.
16. The extendable and retractable conveyor of claim 15 comprising a slidable carriage that suspends the movable spout beneath the hood.
17. The extendable and retractable conveyor of claim 16 comprising guide rails extending along the sides of the housing.
18. The extendable and retractable conveyor of claim 17 wherein the slidable carriage comprises sliders or rollers configured to slide or roll in the guide rails to displace the slidable carriage relative to the housing.
19. The extendable and retractable conveyor of claim 16 comprising a drive mechanism connected to the slidable carriage to displace the slidable carriage and the movable spout relative to the housing.
20. The extendable and retractable conveyor of claim 19 wherein the drive mechanism comprises a drive motor and drive track that drives the slidable carriage along the housing.
21. The extendable and retractable conveyor of claim 20 wherein the drive motor and the drive track are mounted on a top of the housing.
22. The extendable and retractable conveyor of claim 20 wherein the drive motor and the drive track are mounted on a side of the housing.
23. The extendable and retractable conveyor of claim 19 wherein the drive mechanism comprises a linear actuator that drives the slidable carriage along the housing.
24. The extendable and retractable conveyor of claim 15 wherein the movable spout comprises a forward wall slanted at a first angle and a rearward wall slanted at a second angle, wherein the first and second angles are different.
25. The extendable and retractable conveyor of claim 15 wherein the movable spout includes U-shaped channels for sliding over respective rails secured by hangers to the housing.
26. The extendable and retractable conveyor of claim 15 comprising an input shaft connectable to a PTO of a tractor and a power transmission unit for transmitting power to an output shaft that connects to a drive pulley of the continuous loop conveyor.
27. The extendable and retractable conveyor of claim 26 wherein the input shaft is parallel to a direction of conveyance.
28. The extendable and retractable conveyor of claim 16 comprising a motor to displace the slidable carriage, wherein the motor is disposed beneath the housing.
