The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Manure transport device for livestock breeding operations consisting of a circulating, driven manure conveyor belt (1) arranged underneath a stall floor, which belt has at least one drive roller (2) and at least one driven return roller (3), wherein
a) the return roller (3) is arranged with its drive unit (4) in a floating manner, and
b) an adjustment device (5) acting on the drive unit (4) effects a tensioning of the manure conveyor belt (1) in an intermittent manner.
2. Manure transport device as claimed in claim 1, wherein the adjustment device (5) is formed as a hydraulic or pneumatic pistoncylinder arrangement (6).
3. Manure transport device as claimed in claim 1, wherein guide shields (7, 8) are arranged in the region of the drive roller (2) and the return roller (3) on both sides of the manure conveyor belt (1).
4. Manure transport device as claimed in claim 1, wherein
a) the rotational movement of the return roller (3) of the drive unit (4) can be impelled in the direction opposite to that of the rotational movement of the drive roller (2) of the drive unit (10), and
