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.

a discharge spout at the upper discharge end for discharging the particulate material from the conveyor duct;

at least one ground wheel on the hopper for supporting the hopper for movement over the ground;

and a mounting assembly for mounting the conveyor duct on the container for movement relative thereto, the mounting assembly comprising;

a support bracket mounted on the side wall of the container;

a first portion mounted on the support bracket for pivotal movement about an upright axis such that the first portion can turn about the upright axis from a position along the side wall of the container to a position extending outwardly from the side wall of the container;

an arm portion having an inner end mounted on the first portion for pivotal movement about a transverse axis on the first portion such that the arm portion can move from a raised position standing substantially vertically upwardly from the first portion along the side wall of the container to a lowered position extending outwardly from the side wall of the container;

a drive member for driving movement of the arm portion between the raised and lowered positions;

said at least one ground wheel being arranged to support the hopper while allowing rolling movement of the ground wheel in a direction longitudinally of the conveyor duct;

and a swivel connection between the outer end of the arm portion and the conveyor duct at a position on the conveyor duct intermediate the upper and lower ends;

the swivel connection being arranged to support the conveyor duct at the outer end of the arm portion;

the swivel connection being arranged to allow the conveyor duct to pivot about a horizontal axis transverse to the duct such that the conveyor duct can change in angle relative to the arm portion as the arm portion moves between the raised and lowered positions;

the swivel connection being arranged such that, with the hopper resting on the ground wheel in contact with the ground and the arm portion in the lowered position extending outwardly from the side wall of the container, the conveyor duct extends longitudinally of the arm portion and is held such that the conveyor duct passes upwardly above the outer end of the arm portion;

the swivel connection being arranged such that movement of the arm portion from the lowered position to the raised position causes the hopper to be pulled in toward the container while lifting the upper end of the conveyor duct upward, while the at least one ground wheel rolls over the around and while maintaining the conveyor duct in position relative to the outer end of the arm portion such that the conveyor duct passes upwardly above the outer end of the arm portion;

and the swivel connection being arranged to allow the conveyor duct to pivot about an upright axis at the outer end of the arm portion.

2. The apparatus according to claim 1 wherein the swivel connection includes an upright post which extends from the outer end of the arm upwardly to the conveyor duct and a coupling which controls an angle of the post relative to the arm portion to maintain the post upright as the arm portion moves between the raised and lowered positions.

3. The apparatus according to claim 2 wherein the post is mounted on the arm portion for pivotal movement about an axis longitudinal of the post so as to provide said upright axis at the outer end of the arm portion.

4. The apparatus according to claim 2 wherein the conveyor duct is pivotally connected to the upper end of the post for pivotal movement about an axis transverse to the post so as to define the horizontal axis.

5. The apparatus according to claim 2 wherein the coupling includes a link extending from the first portion to the post and extending along the arm portion generally parallel thereto.

6. The apparatus according to claim 1 wherein the drive member comprises a hydraulic cylinder.

7. The apparatus according to claim 1 wherein the arm portion is telescopic.

8. The apparatus according to claim 1 wherein the hopper includes two side walls each extending generally longitudinally of the conveyor duct and an end wall generally transverse to the side walls, wherein the at least one ground wheel of the hopper comprises two pairs of ground wheels, wherein each pair of ground wheels is arranged at a respective side wall of the hopper for supporting the respective side wall, wherein each wheel comprises a castor wheel mounted for swivel movement about a generally upstanding axis and wherein each pair of wheels is mounted at respective ends of a respective pivotal beam extending along the respective side wall of the hopper with each of the respective pivotal beams being mounted for independent pivotal movement about an axis transverse to the side walls of the hopper.

9. Apparatus comprising:

a container having a side wall;

a conveyor duct having a conveyor member mounted therein and operable to move a particulate material within the conveyor duct from a lower feed end to an upper discharge end;

a hopper at the lower teed end into which the particulate material can be poured;

a discharge spout at the upper discharge end for discharging the particulate material from the conveyor duct;

and a mounting assembly for mounting the conveyor duct on the side wall of the container for movement relative thereto to allow movement of the hopper in a direction inwardly and outwardly substantially at right angles relative to the side wall of the container to different positions of the hopper relative to the side wall of the container;

wherein the hopper includes two side walls each extending generally longitudinally of the conveyor duct and an end wall generally transverse to the side walls;

wherein the hopper is supported on two pairs of ground wheels,

said ground wheels being arranged to support the hopper while allowing rolling movement of the ground wheels in a direction longitudinally of the conveyor duct;

wherein each pair of ground wheels is being arranged at a respective side wall of the hopper for supporting the respective side wall;

wherein each ground wheel comprises a castor wheel mounted for swivel movement about a generally upstanding axis;

and wherein each pair of ground wheels is mounted at respective ends of a respective pivotal beam extending along the respective side wall of the hopper with each of the respective pivotal beams being mounted for independent pivotal movement about an axis transverse to the side walls of the hopper.

10. Apparatus comprising:
