Abstract

A loading vehicle having a pick-up drum with resilient fingers for picking up straw material from the ground and a conveyor drum with conveyor arms, fitted in rows for carrying the material into the vehicle. The pick-up drum and the conveyor drum are disposed with respect to each other so that the conveying direction of the material is abruptly changed when the material is introduced into the path of motion of the conveyors. This produces a damming-up effect causing the material to be distributed over the entire conveyor front, which minimizes the tendency of squeezing between conveyors and the housing wall defining the conveyor duct at one side. The change in conveying direction also causes a certain compaction of the material, resulting in a better utilization of the available volume. The structure allows short spacing between the conveyor arms and closely spaced knives are positioned in the conveyor duct so that the blades of straw can be cut in small pieces which are suitable for ensilage.

Claims9

Dependent claims

A loading vehicle for picking up and transporting straw material, comprising:

a body for holding straw material;
a rotary pick-up drum which is fitted at the front end of the body and has resilient pick-up fingers for passing the straw material up to a rotary conveyor drum including a conveyor drum inlet and a conveyor drum outlet and having conveyor arms fitted in rows for conveying the material up into the body of the vehicle through a duct, which at one side is defined by a housing at the outlet of the conveyor drum and at another side by stationary strippers between which the conveyor arms pass and which strip the conveyed material from the conveyor arms, the pick-up drum rotating in the same direction of rotation as the conveyor drum and positioned obliquely below and behind the conveyor drum so that the conveying direction of the straw material is abruptly changed at the inlet to the conveyor drum from a generally upward and rearward direction to a generally downward and forward direction to compact the straw material and equalize the distribution thereof across the conveyor drum inlet.
