Abstract

A dump unit comprises a main chassis ( 2 ); a metallic body ( 3 ) for containing a bulk material, wherein the bulk material can be discharged from one end of the metallic body; a hydraulic actuator ( 8 ) for lifting the discharge end of the metallic body with respect to the chassis; and at least one metallic conveyor (E) located on the floor of the body ( 3 ), which is operable to discharge the bulk material from the body.

First claim

The invention claimed is:

1. A dump unit for use in mechanical harvesting of tobacco comprising:
a main chassis;
a coupling at a forward end of the chassis;
a door at a rearward end of the chassis, the door having an open position and a closed position;
a metallic body for containing a bulk material comprising tobacco leaves, the metallic body having a floor and side walls, wherein the bulk material can be discharged from one end of the metallic body;
a hydraulic actuator attached between the chassis and the floor of the metallic body for lifting the discharge end of the metallic body with respect to the chassis;
at least one metallic conveyor comprising a metallic conveyor belt located on the floor of the body, which is operable to discharge the bulk material from the body, wherein the metallic conveyor belt has an adjustable operating speed which is between 0.04 and 1.4 m/s; and
a hydraulic motor for driving the conveyer.

2. The dump unit of claim 1 , wherein the chassis has at least two pairs of wheels.

3. The dump unit of claim 1 , wherein the body is assembled from metal profiles or panels.

4. The dump unit of claim 1 , wherein the body has a substantially rectangular shape for holding the bulk material.

5. The dump unit of claim 1 , wherein the door is an overhead door through which the bulk material may be discharged from the dump unit and further wherein the door has a rocker type opening and closing movement.

6. The dump unit of claim 5 , further comprising linear actuators for opening the door to discharge the bulk material.

7. The dump unit of claim 1 , wherein the operating speed of the metallic conveyor belt is between 0.04 and 0.08 m/s.

8. The dump unit of claim 1 , wherein a height of the metallic conveyor belt at the discharge end can be varied between 800 mm and 2600 mm.

9. The dump unit according to claim 8 , wherein the height of the metallic conveyor belt is substantially 1,800 mm.

10. The dump unit according to claim 9 , wherein the body is of a bulk carrier type.

11. The dump unit of claim 1 , further comprising at least one support system with height adjustment.
