Agricultural machine e.g. stone burier type rotary tiller used with agricultural vehicle e.g. tractor, has processing chamber inlet opening whose front edge is hinged to peripheral wall so that front edge can rotate about an axis

摘要

Agricultural machine. Agricultural machine having a processing chamber (1) in which an object or material is processed, a first wall (3) surrounding processing chamber (1), an inlet opening (5) which communicates it with the outside and which has a front edge (9), and a rotary mechanism (7) that causes the acceleration of the object or material and its projection against first wall (3). Front edge (9) is hinged with respect to first wall (3) so that it is suitable for rotating when receiving impacts and first wall (3) is made, at least partially, from an elastomeric material. This way the machine's service life is extended, the noise level is reduced, a negative aesthetic appearance is avoided and it is possible to process materials, such as earth, having a higher moisture content.
