Loading equipment comprising a pick-up mechanism for picking up agricultural bulk material such as grass or hay, and having a conveying channel adjoining the take-up mechanism, and a conveyor having a conveying drum which rotates about a transverse axis is disclosed. At its periphery the drum is provided with feed combs having prongs that are pivotable about an axis, the feed prongs of the combs extending into the conveying channel and being controlled during rotation such that during conveying, each feed comb is moved by a crank arm into a radial position and during movement outside the conveying channel it is moved into a folded position. The conveying drum drive and control assembly are designed so that the drum, while compact in design, can be adapted to many different operating conditions without any major constructional changes in that the axis of the conveying drum is stationary and the axis carries within the drum at least one eccentric disc on which a control ring is rotatably supported which is provided with a coupling connected to the conveying drum, and actuating arms which are each articulated at one end to the control ring and at the other end to the associated crank arm.
A loading equipment comprising a take-up means for taking up agricultural bulk material such as grass or hay, and further comprising a conveying channel adjoining said take-up means, and a conveying means having a conveying drum which rotates about an axis and which is provided at its circumference with feed combs which consist of feed prongs and which are each supported for pivoting about an axis, the feed prongs of said feed combs extending into said conveying channel and being controlled during circulation such that during feeding, each feed comb is moved by means of a crank arm into an approximately radial position and during circulation outside the conveying channel into a folded position, characterized in that said axis (2) of said conveying drum (1) is stationary and that inside said drum (1) said axis (2) carries at least one eccentric disc (8) on which a control ring (7 or 33 or 36, respectively) is rotatably supported which is provided with a coupling means connected to said conveying drum (1), and actuating arm (47) which are each articulated at one end thereof to said control ring (7) and at the other end thereof to the associated crank arm (38).
