Claims (3)

\ y Vibratory conveyor of the structure described above claims: to be designed so that it can be Herge in large lengths without the drive energy 1. Two-mass vibratory conveyor with an essential additional mass as a result of the design Conveyor trough od. The like. Trained vibrating 5 are about deoi necessary amount for promotion wet, one below must be arranged parallel to this. Pray counter mass, these masses in regular This task is achieved according to the invention Coupling distances, under the conveyance litter, that the counterweight in the area between the angled spring elements and a coupling field an increased moment of resistance separately arranged unbalance exciter, which has flexural vibrations,
«One rigid in the direction of oscillation, perpendicular to it each. The invention assumes that the but elastic coupling with the counterweight oscillating mass via the coupling fields in the counter-connected is, characterized by the mass entered bending vibration so jeopardized that the counterweight (3) is in the area between, the longer the conveyor and thus the counterweight When the coupling springs (9) have an increased counterweight. Because of this, one has hitherto been on Static moment against bending vibrations limited to lengths of 10 to 20 m. Will now shows. If greater overall lengths are aimed at, it stands to reason that the 2. Vibratory conveyor according to claim 1, characterized in that the counter mass is correspondingly over its entire length characterized in that the countermass (3) to be made stable. However, this would be the opposite of one another Profile support (13) is formed, the profile of which ao mass received a weight that is more than that for the in the area between the connection points (16) promotion necessary amount going beyond drive Coupling springs (9) the moment of resistance would make erenergy necessary. Ie invention having elevated stiffeners (17). is based on the fact that the 3. Oscillating springs according to claim 2, characterized in that the countermass in the area of the coupling springs is a sufficient, that the profile girder has an I-girder which has a large section modulus, and Ie- (13) is that as stiffeners its flanges (14) diglich between the coupling springs an additional having connecting bridges (17). Moment of resistance must be created to the Flexural vibrations take their adverse effect. 30 Vibratory conveyors of other types are known (DT-AS 1 136 936), in which on the counterweight through weakening incisions or through attached, possibly displaceable masses The invention relates to a two-mass oscillation oscillation behavior to be influenced, but conveyor with an od as a conveyor trough deten oscillating mass, one below parallel to the vibration exciter in the form of a connecting rod, for example this arranged counter-mass, these masses in the middle of the longitudinal extent on the counter-normal Coupling distances, is arranged under the conveyor mass and on the oscillating mass in 'Throw angle adjusted spring elements and a direction of the coupling springs acts. Since here about Separately arranged unbalance exciter, which bends unevenly over 4 ° the length of the conveyor Stresses that are rigid in the direction of oscillation and that are perpendicular to it should be the result of the above elastic coupling with the counter mass named measures can be remedied, whereby is bound. but in contrast to the invention, the natural Vibratory conveyors with this training are reduced in the supply. Nor is it Resonance range operated, with a detuning 45 stiffening, because the incisions countermove of about 10 ° / o has proven favorable. The masses weakened and by the movable La countermass Due to the construction of the fermentation of the additional masses, there is no stiffening effect Drive with counter-rotating masses and the con- is achieved. After all, are with this sponsor construction of the coupling only longitudinal bending vibrations required for its function, excited. The counter-mass points to the 5 »while in the case of a conveyor of the type un-oscillating mass only a very small oscillation amplitude in the desired and eliminated by the invention who ratio from Z.

The latest development in this formed a profile beam, its profile in the field Regard is for example in DT-AS 1 258 643 55 between the connection points of the coupling springs described. Due to the stiffeners increasing the moment of resistance at an angle Spring elements are assigned to the counter mass forces. The normal profile beam would be used for large entered, which have an effect as bending vibrations - overall lengths tear due to the bending vibrations, ken. These are harmless in the case of small overall lengths, but it is obtained from the coupling springs or their and are taken up by the construction of the counterweight 60 connecting parts and the interposed connections, reinforcements - seen over the entire length - Since now the mass of the conveyor and the increased, possibly constant winder Good the necessary drive energy inventory morale.
