The first latch elements 128 and form leave a blank for kayser the He of the second latch elements 130 of portion 106 and two guiding segments 104
132.First latch elements 128 are attached to suction nozzle 30, thus suction nozzle by suction channel sleeve pipe 62 and suction channel section 58 it
Between anti-relative rotation connection can relative stiff dough exhaustion equipment 12 move.Second latch elements 130 and 132 are attached to stiff dough suction
Net plant 12.
In the latched position for limiting initial position, as shown in Figure 6 schematically, the first latch elements 128 with
Second latch elements 130 are rabbeted.Kayser raised 84 constitutes the element 134 of the pretension of kayser governor motion 126, and in kayser machine is adjusted
In the initial position that Fig. 6 of structure 126 schematically shows, the element of pretension causes the first and second latch elements 128 and 130 to keep
In latched position.
Suction channel sleeve pipe 62 can be reversed with respect to housing 16.But to achieve, the element 134 of pretension must be directed towards
The direction of pivot center 66 somewhat pivots so that the first latch elements 128 and the second latch elements 130 are realized disengaging interlocking.Such as
Fruit suction channel sleeve pipe 62 continues to reverse, then the first latch elements 128 are snapped in the second latch elements 132, that is, are blocked
In being locked into guiding segments 104.But in the guiding segments, suction channel sleeve pipe 62 can be realized around the relative shell of pivot center 66
Continuous torsion of the body 16 in about 160 ° of angle range.
The element 134 of pretension is constructed as described on the second coupling arrangement 52.As an alternative also, it is contemplated that pre-
Tight element 134 is arranged on the first coupling arrangement 50.The element of pretension is configured to the form of spring, is specifically leaf spring
Form.
Stiff dough exhaustion equipment 12 also includes resetting means 136, its be used for by suction nozzle 30 and stiff dough exhaust equipment 12 from due to
The turned position of the initial position deflection schematically illustrated around the relative Figure 14 of the rotation of pivot center 66 branches back to initially automatically
