Egg carrying frame

The experience concerns one on the three-point linkage of a tractor Anfoau.ba.ren Egg support frame for attaching and digging out harrow fields, Eriiaelwalzen or similar tools, where the

Egg support frame mainly made up of a front and a leaning one with it

easily detachable, assembly consists. About the front support frame is

Carcass socket for the three-point linkage of the tractor Mistake. Are on the front support frame, for example Harrow fields and attached to the rear support frame ICr iiiae! Rollers, this is how it is for this combination of devices to work perfectly required that the crumbs ¥ i? algeii with a bestini »- different loads on the soil depending on the type of soil be pressed, Yiobei a vertical mobility of the on the Kriiraelwalzen örüciseßöeo Teiles öes Hinterrahnjens because of more suitable Unevenness in the floor voi "it's sweet.

There are Eggeiitragraßmen lait a front and ice iiinterea assembly become known, in which a parallelogranmartiges coupling link is installed between the two assemblies, which allows a vertical displacement of the rear support frame, whereby this support frame loads the Krtimelwalzen with its weight. In other known designs, both assemblies are start with each other tied together. The connection point of the sciilepper top link, which is shaped as an elongated hole, allows limited mobility in height. In these versions, too, the Krüiaelxvaljfeea burdened by the weight of the supporting frame,

The invention has made sure the task to allow the coupling member eliminated and create a direct zn, movable connection between the front and rear Tragraheen, wherein the rear support frame to make up freely movable _+, and the load on the Krülaelwalzen adjustable.

As a further object of the invention, the load on the crumbling rollers should also be made controllable in the known embodiment with the coupling member. In accordance with the invention, this is achieved in that the lower support frame is hinged directly to the front support frame with its front, lower connection points and the two support frames disreh a resilient threaded spindle or one
adjustable spring are connected. It is advantageous if the preload of the spring can be adjusted.

In a special embodiment, the resilient top link
dureii a freely collapsible, unsprung upper link
or replaced by a chain. This is possible in the case of very slight gusts, since in this case the partial weight of the rear eye, which is pressing on the rollers, is completely sufficient. This arrangement also allows the rear frame to move upward.

A controllable load in the known design with coupling link is achieved in that in the coupling parallelogranra
an adjustable spring is arranged.

The innovation is shown in the drawing. Show it

The front egg support frame (3) connected to the three-point linkage (i, 2) of the tractor is easily detachable and rotatable with the rear support frame (4) at points (5). For example
after Pig. 1 the top link (6) connects the two support frames
at their upper coupling points (7, 8) with one another. The either

by the weight of the rear support frame (4) or by the spring spindle (6) generated load on the Krüniel rollers (10) is advantageously at a certain distance (a) initiated from the center line of the crumbling rollers (12), whereby the rear crumb body is always a little more loaded than the one in front and this has the advantage that the crumbs cannot dig into the ground.

The one in Pig. 2, the controllable loading of the Krtüaelwalzea is achieved by the adjustable tension spring (18), which is activated on the one hand as the front support frame (3) and on the other hand a »rear support frame (4). In this example, the preload is adjusted by the nut (19), while the spindle (20) adjustably limits the vertical downward movement of the rear support frame (21), which presses on the crumbling rollers, whereby the long loea (22), however, allows the crumbling rollers to move allowed upwards.

3 shows an embodiment of a spring spindle which is characterized by the turnbuckle (15) and the spring (16), the pretension of which can be adjusted by the nut (17) .

In Fig. 4 a further embodiment is shown, wherein the front support frame carries a spring tine harrow (23), and a coupling link is installed between the two support frames (M>)

of the Hinterrahiaen (4) in the vertical direction auxeh the parallelogramia effect of the coupling link is movable. The regulation of the load on the crumbling rollers is achieved by the spring-loaded spindle (14) arranged in the coupling element or by an adjustable tension spring (not shown).

Claims (4)

Protection claims 1 «) Egg support frame that can be attached to the three-point linkage of a tractor with a front and a detachable rear assembly, characterized in that the rear, the supporting frame (4) carrying the Krumelwalzen with its lower Änschlupunkten (5) rotatable on the front support frame (3) is connected, and that the spring spindle connected to the two support frames (6) or adjustable Spring (18) allows a controllable load on the crumbling rollers (1O). 2.) Egg support frame according to claim 1, characterized in that the support points (11) of the rear support frame (4) at a certain distance (a) from the center line (12) of the crumbling rollers (lo), and that this distance means Chain (16) is adjustable. 3.) Egg support frame according to claim 1, characterized in that the spring spindle consists of the turnbuckle (15) and the spring (16), the preload of the spring being adjustable by means of a nut (17). 4.) Egg support frame, consisting of a front and a rear assembly with arranged between these two Coupling link, characterized in that an adjustable, resilient element (14) is built into the coupling link (13), with which the load on the crumbling rollers (10) can be regulated « 5 ») Egg support frame according to claim 1, characterized in that that the rear support frame (4) with its lower connection points (5) is articulated to the front support frame (3) is and that both support frames are connected at the top by a collapsible spindle or a variable-length chain are.
