Pre-shaker.

Patented in the German Empire on October 30, 1910.

To the work of the feeders on threshing machines like that. to shape that feed of the grain to the threshing drum is carried out as regularly as possible, one has the effect the feeder finger tries to support the grain department by that the feeder fingers a pre-shaker or loosener was placed in front of the got its drive from the feeder shaft.

ίο Since this drive is completely inevitable, so the pre-shaker must perform exactly the same movement with each revolution of the feeder shaft, regardless of whether the grain is fed into the hopper in regular or irregular quantities. The consequence of this is that the advance of the grain fluctuates between wide limits, the gait of the machine and its power consumption are accordingly irregular and it is not uncommon for serious operational disruptions to occur due to complete blockage of the hopper.

To eliminate these disadvantages is the purpose of the present innovation, which is thereby achieved is that the pre-shaker or loosener is positively raised and automatically sinks under the load resting on him and by his own weight. In the case of irregular On farms, he is now held in a raised position by part of the threshed material that has stepped under him, and can also it can also be locked by a latch if the hopper is sudden and excessive is filled. If the pre-shaker locks itself, the feeder fingers can capture only small amounts of the threshed crop, and the crop that was last abandoned is thereby withheld until the first thrown in in divided quantities from those in known Wise working feeder fingers is removed.

This thorough loosening of the threshed material before it enters the funnel throat and the automatic locking of the pre-shaker in the event of irregular supply of the Threshed material is particularly important with moist grain, as disturbing Prevents congestion and saves time and operating power.

In the drawing, an embodiment of the innovation is shown schematically; it shows:

Fig. Ι a side view and

2 shows a cross section of the self-inserter.

The feed space α of the hopper b is formed by the frame walls c of the fixed and the swinging slotted wall d and e . In the below the wall d lying feeder shaft f the eccentric is fixed h, the rod * fitting lever is hinged k to the loose on the shaft / on which also the arms I and m and the the Vorschüttler or plow forming rakes are attached η . The lever k engages at a certain eccentric position to lift the

Rake η behind the pin ο of the arm I and thereby causes the rotation of the shaft /.

In regular operations, these parts work together in such a way that the rake η is positively raised once with each revolution of the shaft f to loosen the threshed material, and then sinks under the weight of the latter and its own weight

ίο back to the starting position. If, on the other hand, the space α is overcrowded and as a result too large a part of the threshed material tries to get to the threshing drum, some of the threshed material also comes under the tines of the rake n, which is why it can only partially or not at all sink. As a result, the threshed material present in excess is retained until the feed arms g have eliminated the cause of the jam by properly dividing them off. Here, the tines of the rake sink deeper and deeper after each force-fit lifting of the rake tines until they finally again regularly touch the wall d after each revolution of the shaft f , which occurs after the cause of the fault has been eliminated. The feed arms g are in such a relationship with the rake representing the pre-shaker or loosener that one series of feeder arms is always in the lowered position. Separates the threshed material lying in its area more loosely and feeds it to the threshing drum, while the other series of feeder arms passes through the threshed material with the rake raised without any noticeable impact.

If the rake η is to remain in the raised position in the event of sudden and excessive overfilling of the supply space a to shut down the distributor, a locking pin p held down against the action of a spring during regular operations is triggered, the beveled nose of which is then placed behind the arm m and thereby the Rake η in the position indicated by dash-dotted lines in FIG. 2 / from which position it can only be removed by retracting the locking pin φ. The triggering of this locking pin is best set up in such a way that it can be carried out from any point by means of a rod or pull rope.

The funnel wall e opposite the feeder is attached to a shaft r mounted in uprights q , the arm s of which is articulated by means of the intermediate member t to the lever ν swinging around the point u. This lies with its eccentrically curved arm w against a pressure roller χ of the tine carrier carried by the shaft r , with which the tines υ are firmly connected. If the pressure now increases, the receding wall e pushes the prongs y forward in a known manner and supports the pre-shaker η in its endeavor to eliminate the cause of the pressure.

Claims (1)

Patent claim: Self-inserter for threshing machines with a pre-shaker driven by the feeder shaft, characterized in that the pre-shaker (s) is only raised in a force-locking manner so that it remains in the raised position in the event of a jam in the feed hopper (b) or by a spring action that can be triggered from any point standing locking bolt (φ) can be determined. 1 sheet of drawings.
