CLASS 45 e. GROUP

Those present on the motorized and steam threshing machines in use Post-shakers should serve the purpose that is still loosened in the ears or seed pods remove any remaining grains. It is desirable that the amplitude or the inclination of the fingers of the post-shaker changed and the type or condition adapted to the respective threshed material

ίο can be. Adjustable shakers are also already known, namely this well-known post-shaker is in a bearing block stored on the return floor below the straw walker.

In contrast, according to the present invention, the shaking rake is attached to pendulum rods suspended from the solid housing of the threshing machine and from the straw walker using driven by a handlebar parallelogram. the

20 two connecting rods, which lead up and down to the machine housing, can be adjusted in their inclination by relocating their suspension points. Through this the inclination and angle of oscillation of the rake fingers is also changed.

The innovation offers the advantage that the post-shaker carries out its vibrations together with the main shaker and that it can be retrofitted in all threshing machines, regardless of the Distance between shaker and return floor.

The invention is illustrated in the drawing, namely Fig. 1 shows the rear Part of a threshing machine in the side view and Fig. 2 the adjustable lever linkage of the Shaker.

As can be seen from Fig. Ι, the loading of the main shaker α and b are set in an oscillating motion by a crankshaft c in a known manner.

The threshed material is transferred from the main shaker to the secondary shaker d. This post-shaker consists of a large number of bars lying parallel next to one another which, according to the illustrated embodiment, are fastened to a cross bar e made of profile iron. The axis e ^{1 of} this rod e is guided through a slot in the side walls of the machine and firmly connected to a Hebei f. This lever f is articulated to the lever h mounted at g ¹ and to the rods i and k , the latter of which are connected in the same way to a lever m which can swing about I ^1.

The articulated arc η of the parallelogram /, i, k, m is rigidly connected to a cross member 0, which sits firmly on a support frame of group b of the loading of the main shaker and of. this is moved back and forth. This movement is followed by the lever m, which swings about the bolt I ¹ , and the lever h, which swings about the bolt g ¹ , whereby the shaker d, in addition to a reciprocating movement, also becomes a movement about the axis e ¹ on 6g and low vibrating movement is caused. The different setting of the post-shaker is brought about by the fact that the

Trunnion g ^{1 is moved} on a fitting φ to g ² or g ³ . The pin I ^{1 is moved} to the fittings q according to Z ² or P in a corresponding manner.

From Fig. 2, the assumed three different settings of the post-shaker ' can be seen, of which in threshed material with very loosely sitting seeds the flattest and the steepest is used for threshed material with very firmly seated seeds.

Claims (1)

Patent claim:
Post-shaker for threshing machines, characterized in that the axis (e ¹ ) of the post -shaker (ä) is inevitably connected to a group (b) of the shaking shakers of the main shaker (a, b) , with the help of pendulums (h, m) adjustable handlebar parallelogram (m, i, k, f, h) attached to the machine frame is moved. 1 sheet of drawings.
