: The invention relates to a conveyor element, such as a reel or tine drum, for introduction harvesting machines which are determined by stalk-shaped material and which rotate during operation and are fitted with rows of spring tines, which are at the foot of a support web are anchored and each have a spring loop, which between them parallel to the axis of rotation of the conveyor member supporting stop surfaces of the support web summarizes, according to patent application C 25975III / 45 c the foot of each spring prong is hooked with the support bar, partially encompassing it Spring loop rests against the support web with elastic pretension and additionally through the support web effective stop means is supported in the plane of rotation of the conveyor organ. Funding bodies like Reels and the like with such prong fastenings have proven useful for introducing stalk-shaped Well proven specific harvesters well. Occasionally, however, the choice of which to manufacture the prongs of certain materials with regard to the suspension properties are limited by the fact that the positive engagement of the loops between the transversely and longitudinally supporting stops of the Support webs must be maintained exclusively by elastic bias. A proportionate one low preload would therefore involve the risk that, for example, in the event of a rebound a prong, the positive engagement is inadvertently released.

The invention is therefore based on the object of the conveying organs described in the main patent Art to design the prong fastening in such a way that the positive engagement of the elastic deformation capability utilizing Spring loops is retained, but an unintentional loosening of the prongs by an additional Security measure is excluded. According to the invention, this is essentially achieved by the spring loops sweeping, their engagement between the stop surfaces securing, held on the support web Cross bar reached. These crossbars remain during normal operation of the conveyor ineffective, but they prevent, for example, with a rebound or the like., spring tines unintentionally detach from the support web. This improves operational safety and makes it possible even quite flexible tines according to the principle shown in the main patent, permanently free of play to hold.

The invention can be implemented in a number of ways. It is particularly easy to cut the opening of the carrying conveyor element, such as the reel or the tine drum, which forms a stop surface.

Associate the web-grasping spring loop of a prong with a depth of engagement, one for pushing through a cross bar sufficient part of the area bounded by the loop over the inner surface the supporting web wall can protrude. By means of an analogous, for example curved, profile shape Such arrangements can be made of the cross-sectional area of the support web containing the openings perform in such a way that the deformations required to engage the loops in the openings remain within the limits given by the elasticity, and accordingly also the Pre-tensions can be selected with which the loops are held in the openings. These However, preloads can be used for securing purposes thanks to the additional use of security Cross bars now reduce if necessary without reducing operational reliability, so that on Due to the reduction in internal stresses, the spring tines are sometimes more durable.

The crossbars can also be designed in various ways. It is particularly easy several juxtaposed tine foot loops form a common crossbar to be assigned to a rod that can be pushed in parallel to the support web. To replace a spring prong one would have to Such a rod may, however, be set back a long way, but this is practical

no difficulties, because the prongs temporarily unlocked due to the intervention their supporting parts maintaining elastic pre-stresses remain in the appropriate position, so that the rod forming the crossbar can easily be pushed in again. It however, it is also possible for each tine foot or subgroups comprising only a few tines to have one assign your own crossbar. Such designs can preferably be realized if support webs with a channel-shaped cross-section are used, in which the interior space for introduction or Loosening crossbars is accessible.

The free ends of the Zinkenfußteile can be described in patent application C 25975 ΠΙ / 45 c type be designed. In some cases, however, it is more expedient to convert the free end of a tine foot into a Z-shaped one To form hooks that hold in an opening in the supporting web wall. This training leaves one extensive freedom of movement in the choice of the cross-section of the support web and enables it in particular simple way of hanging the spring tines and locking them into place under elastic deformation.

In the drawing, the subject matter of the invention is shown in exemplary embodiments. It shows

1 shows a particular one to be assigned to a combine harvester Reel in a graphical representation,

F i g. 2 in a diagrammatic representation a tine attachment on a support web of the reel in a larger Scale

Fig. 3 shows a section-ΠΙ according to Fig. 1 in a larger Scale,

F i g. 4 in FIG. 3 shows a modified version, similar to the illustration.

The in F i g. 1 reel is rotatably seated on supports 10 and is rotating for use driven. Support webs 12 extend between its side frames 11, each having a number of Wear spring tines 13. The support webs 12 are shown in FIG. 1 depending on the rotational position of the The reel is rotated about its axis or shaft 14 with respect to the side frames 11, around whichever is desired Effect of the spring tines on the goods to be processed. In the case of the FIGS. 2 3 and 3 has each support web of the reel over the substantial part of its length a C-shaped cross-section. Such profiles can be made from sheet metal cuts by drawing or Produce folding in a simple way »The ends of the C-shaped cross-sections having support web members 60 are attached to pipe sections 61 which establish the connection with the side frames 11 of the reel. The spring prongs each comprise a bow-shaped end region 62 with an angled end 63 and a loop 64. The angled end 63 lies in a peripheral recess of the support web member 60. The part of the loop 64 facing the bow-shaped area 63 lies in an opening 65 in the lower area of the support member 60 a. This opening 65 is the curvature of the loop adapted in such a way that between the inner surface of the 'wall of the' support web member and the loop 64 a cross bar 66 can be inserted. This cross bar 66 is in normal use of the The reel is not used, since the loop 64 grips with pretension in the opening 65, but ver * it prevents with security an unintentional loosening of the Federzinkej if, for example, for any reason on their exposed lower Part of a force directed to the left in Fig. 3 is expressed will.

Fig. 2 shows the one at one end of a support web member 60 arranged spring prongs, it can also be seen that the crossbar is from a rod is formed, the several or all spring prongs lying in a row in the position of use can secure. The cross bar 66 has a handle part 67 for convenient handling. Moreover shows F i g. 2, that the end region of the support frame member in its upper zone becomes a sleeve-shaped part 68 is deformed, which establishes the connection with the pipe section 61.

The arrangement according to FIG. 4 corresponds essentially to that according to FIGS. 2 and 3, but here the foot part of the spring tine grips with a Z-shaped bent end area 69 in a bore 70 of the support frame member 60 and thus creates an anchoring that meets the requirements. As in the exemplary embodiment according to FIGS. 2 and 3, the loop 64 engages in an opening 65 in the support web and is secured in the engaged position by a cross bar 66.

As already mentioned, the embodiments shown are only examples of realizations the invention. This is not limited to this. On the contrary, there are many other explanations possible. For example, the profile shape of the support web compared to the exemplary embodiments can be varied in many ways. Each loop 64 could be secured by its own crossbar, but such designs usually require higher manufacturing costs, while on the other hand the common Securing a number of spring tines hardly offers any disadvantages, since even when unlocked the spring tines maintain their correct position for use. The bracket of the cross bar on the Support web can be designed differently. The supporting bridge could, in some cases on its outer surface, have special bolt guides.
