Abstract

A container for example for a seeder includes a filling conveyor mounted on one with a bottom hopper and an upper filling spout with the conveyor being movable in a direction inwardly and outwardly relative to the side of the container to different positions relative to the container for cooperation with a supply. This is achieved by mounting the conveyor on a swivel coupling at the outer end of an arm which can be raised and lowered by pivotal movement about an inner end at the container. The hopper is supported on two pairs of ground wheels, each pair being arranged on a respective side of the hopper for supporting the respective side and each pair comprising a respective one of a pair of castor wheels mounted at respective ends of a pivotal beam extending along the respective side of the hopper and pivotal about an axis transverse to the hopper.

Claims

1. A conveyor apparatus for transporting particulate material from a supply discharge to an inlet of a container, the apparatus comprising:

a conveyor duct having an opening at an inlet end and a discharge end;

an endless belt mounted in the conveyor duct and engaged by a lower roller at the opening at the inlet end so that an upper run of the belt passes the opening and carries the material along the duct;

a feed duct attached to the inlet end of the conveyor duct;

the feed duct including a top opening with a hopper attached thereto to guide material from the supply discharge into the top opening;

an endless belt mounted in the feed duct and engaged by a lower roller at a lower end and an upper roller at an upper end so that an upper run of the belt passes the opening and carries the material along the feed duct;

the feed duct being movable between a retracted stored position and a deployed position;

in the deployed position the feed duct extending outwardly from the inlet end of the conveyor duct and arranged such that the upper end discharges into the top opening of the conveyor duct;

the feed duct being mounted by a guide track mounted on the conveyor duct and extending longitudinally along the conveyor duct for movement of the feed duct longitudinally of the feed duct between the deployed position and the retracted stored position;

the guide track being arranged to carry the feed duct from the deployed position into the retracted stored position on a top of the conveyor duct.

2. The apparatus according to claim 1 wherein the guide track is arranged to maintain the feed duct as it moves in a direction longitudinal of the conveyor duct so that in the deployed position the feed duct lies in a common axial plane with the conveyor duct.

3. The apparatus according to claim 2 wherein the feed duct is carried at its outer end on a ground engaging wheel fixed for longitudinal movement of the feed duct in the direction longitudinal of the conveyor duct.

4. The apparatus according to claim 3 wherein the ground engaging wheel is carried on arms extending outward from the outer end of the feed duct.

5. The apparatus according to claim 1 wherein the conveyor duct is carried at its outer end on a ground engaging wheel which is rotatable about an upright axis for allowing movement of the outer end of the conveyor duct in different directions.

6. The apparatus according to claim 5 wherein the ground engaging wheel of the conveyor duct is a castor wheel.

7. The apparatus according to claim 5 wherein the ground engaging wheel of the conveyor duct is a carried on a suspension for up and down movement.

8. The apparatus according to claim 1 wherein the conveyor duct is carried on a pivotal support allowing movement of the outer end in different directions.

9. The apparatus according to claim 1 wherein the hopper extends substantially along the full length of the feed duct.

10. The apparatus according to claim 1 wherein the guide track includes a pair of parallel track portions each arranged on a respective side of conveyor duct.

11. The apparatus according to claim 10 wherein the feed duct includes a pair of guide roller assemblies each on a respective side of the feed duct and each cooperating with a respective one of the track portions.

12. The apparatus according to claim 11 wherein each guide roller assembly includes a pair of longitudinally spaced rollers.

13. The apparatus according to claim 11 wherein each guide roller assembly is pivotally connected to a respective side of the feed duct for up and down pivotal movement of the feed duct about a common transverse axis across the conveyor duct.

14. The apparatus according to claim 11 wherein each track portion includes a down turned end portion arranged to allow the inner end of the feed duct to drop downwardly as it moves into the deployed position and to be lifted upwardly as it is moved out of the deployed position.

15. The apparatus according to claim 1 wherein there is provided a drive cylinder for moving the feed duct along the conveyor duct.

16. The apparatus according to claim 1 wherein the feed duct includes a pair of downwardly extending support legs each arranged for engaging onto a respective one of the track portions in the retracted position to hold the feed duct in the retracted position.

17. The apparatus according to claim 1 wherein the feed duct has a hydraulic drive motor for driving the one of the upper and lower rollers thereof.

18. The apparatus according to claim 1 wherein the conveyor duct has a row of openings along the top of the conveyor duct.

19. The apparatus according to claim 1 wherein the conveyor duct includes a cylindrical portion which cups the belt.
