Abstract

THE INVENTION RELATES TO A DEVICE FOR FIXING DOUBLE SPRING FORKS ON SUPPORT TUBES, IN PARTICULAR FOR STRAW LOADING DEVICES. THIS DEVICE IS CHARACTERIZED IN THAT THE SUPPORT 3 IS IN THE SHAPE OF A DOUBLE HALF-SHELL, IN WHICH THE HALF-SHELL 7, IN THE FORM OF EXTERNAL COLLARS 10, 10 AND OF A MEDIAN COLLAR 11, THE SUPPORT TUBE 1 AND THE HALF- SHELL 5, IN THE FORM OF EXTERNAL CLAWS 13, 13 AND A MIDDLE CLAW 14 SURROUND THE SPRINGS OF THE DOUBLE SPRING FORK 2 OVER APPROXIMATELY THEIR HALF

Description

1. Device for fixing spring forks on support tubes, in

  The invention relates to a device for attaching spring forks, in particular for straw loading devices and the like, which allows the change of individual double-spring forks without dismantling of the straw. other construction groups and represents a stable attachment for the forks

  double spring on the support tubes.

  It is known, according to DE-GM 19 58 315, to attach a double spring fork to the support tube of the straw loading device, in which a U-shaped iron surrounds approximately half of the periphery of the straw. carrying tube and, on this occasion, blocks on the support tube, the piece

  middle of double spring fork by means of a screw connection introduced into the support tube.

  This method of attachment certainly allows the exchange without difficulty of forks with double spring defective, that is to say without disassembly of building groups belonging to the straw loading device, but it has the disadvantage that the forks springs rotate in the case of the smallest solicitation and cause damage to neighboring parts and may, for example, be

destroyed themselves.

  A straw loading device is known according to DE-GM 69 19 313, in which each double spring fork is held rigidly in its attachment, fixed on the support tube, in the event of lateral force, for example coming from the movement of the transversal feeder. In addition, a fixation with a slot is fixed on the support tube, in which are guided the ends of the double spring fork. The longitudinal axis of this slot is located in the direction of the guide path of the double spring forks, so that in the case of the smaller side load of the double spring fork, a lateral deviation by the spring is prevented. support on the support. In addition, there is the disadvantage of the rotation of the double spring fork in the case of stresses coming from any direction, because the screw connection which fixes the support on the support tube is not able to prevent and damage already described for the DE-GM

  19 58 315 also occur here on the same scale.

  All other known devices for attaching double spring forks have the same construction of

  principle than that described for DE-GM 69 19 313, so that an additional estimate of the previous state is saved.

  The object of the invention is to create a device 25 for fixing double spring forks on the support tubes of a straw loading device, in which no damage can be caused despite the presence of a mounting, respectively of simple dismantling of individual double-spring forks, by their stresses on neighboring building elements and so that the availability of technical equipment of

harvest is high.

  The object of the invention is to create a device

  for attaching the double-spring forks to the straw-carrying carrying tubes, which re-

  has a seat with all safety against a possibility of rotation of the double spring fork with respect to the support tube in the case of solicitation of

the double spring fork.

  According to the invention, this is achieved by the fact that each double spring fork is arranged together with a support by means of a tensioning screw, which is arranged approximately in the middle between the spring turns of the double spring fork and penetrates approximately radially into the support tube, is fixed on the support tube, the support being, according to the invention, double-shaped in half-shells. One of the half-shells, consisting of an outer collar and a middle collar, loosely surrounds the support tube, substantially to the half and the other half-shell, formed by an outer claw and a middle claw, also taking without play two spring turns of the double spring fork and approximately to half their diameter. It has been found appropriate that all three claws are wider than the collars forming the other half-shells, in order to provide better rotational support to the double-spring fork which is resilient with respect to the support tube. The advantage of the invention lies in the fact that, even in the event of heavy stress on the double-spring fork, any rotation is impossible with respect to the support tube and that the consequential damages for the neighboring construction elements 30 are avoided. ! respectively the damage on the double spring fork itself. The availability of technical harvesting equipment is thus significantly increased. Assembly, respectively disassembly, easy forks

  double spring is contained in this solution.

  The invention is explained below with the aid of an exemplary embodiment. The drawings show: - Figure 1: a side view of the device, Figure 2: an X view according to Figure 1, - Figure 3: a view Y according to Figure 1, 5 - Figure 4: a view Z according to Figure 1 ,

  - Figure 5: a perspective representation of the support.

  On a tube 1 is fixed a double spring fork 2 by means of a double support 3 in the form of a

  half-shell, in which is provided a piercing 4 median.

  The double spring fork, which is placed in a half-shell 5 of the support 3, is rigidly connected with a tensioning screw 8 and a counter nut 9 on the support 1, by means of its fixing hook 6, which is again surrounded by the other half-shell 7 of the support 3. In order to create a connection against any locking in rotation between the support tube 1 and the double-spring fork 2, the half-shell 7 is formed two outer collars 10, 10 'and a middle collar 11. To receive the two coil springs 12, 12' of the double spring fork 2, the half-shell 5 also has two outer claws 13, 13 ' and a middle claw 14 surrounding the two spring turns 12, 12 ', which are arranged wider than the collars 10, 10' to realize the

  Rotational holding of the double spring fork 2.

  The fixing blocking in rotation the double spring fork 2 on the support tube 1, is ensured by the support without play of the half-shell 7 on the support tube 1 and the half-shell 5 on the turns of

spring 12, 12 '. -
