DE573368C - Device for guiding the binding agent through the straw strand of straw presses - Google Patents

Description

Devices are known to facilitate the binding of the bales in straw balers, in which a needle is mounted to swing and slide outside of the baling channel, those for pulling through the one below the strand and running down from a knaul Tying rope is used through the straw strand, the needle being taken along by the advancing strand. With these well-known Devices is the needle when exiting the baling channel by a spring moved back to their original position.

With the known devices it is not possible to use short binding ropes, i. H. Hyphens, to lay the bales. This should be made possible by the subject matter of the invention will. For this purpose, according to the invention, the needle is at the free end of a lying below the baling channel, outside of the baling channel in vertical and horizontal direction pivoted arm articulated, which inevitably so is moved that the needle one end of the binding rope inserted into its eye one after the other pulls from top to bottom through the strand of straw, wraps around the part of the strand of straw that is tied into a bale at the bottom is to be, and then passes through the strand from bottom to top, so that Both ends of the rope are above the ball and after loosening one end the needle can be tied by hand.

The invention is shown in one embodiment in the drawing.

Show it:

Fig. Ι a cross section through the baling channel with the subject matter of the invention,

Fig. 2 is a plan view of the part of the channel through which the binding needle is passed will and

Fig. 3 and 4 schematic representations of the linkage and the binding needle in their highest and lowest position.

The side walls are denoted by α and the bottom of the press channel is denoted by b. In the bottom b- there is the slot-shaped opening c running in the longitudinal direction of the channel, through which the needle α moves during its movements in the vertical direction and in the longitudinal direction of the compression channel a, b . The needle movement is mediated by a push rod e , which is moved by an eccentric (not shown in the drawing) and engages a slide which slides in vertical guides arranged outside the press channel. The carriage consists of a rectangular cross-section f and a rod g, which is guided in a tube h. Is the eye at the end of the rod g protruding from the tube / i at the bottom? a lever k consisting of two parallel legs is rotatably attached, at the free end of which a transverse bolt I is arranged. On the latter, a lever m is rotatably mounted and a vertical line

direction extending lever n attached. The free end of the latter is articulated by a handlebar ο to the lower end p of the binding needle d , while the free end of the lever m rotatable about the bolt I is articulated to the binding needle d by a pin q , the binding needle piece p , q has the same length as the vertically extending lever n. Due to the ίο parts ο and n, which together with the lever m and the binding needle piece p, q form a parallelogram, one leg η of which is always perpendicular, the needle d becomes at their Movements in a vertical direction held in a vertical position. At a fixed part r there is one at his free end with an eyelet, y arm t suspended swingably, and in the eyelet an extension m _{t of} the lever m is rotatably fastened by means of a bolt. In the needle position according to Fig. 1, the needle point protrudes from the top of the straw layer, the upper end surface of which is indicated by the line u. One end of the usual short binding rope, as used for hand tying, is threaded into the eye of the needle. During threading, the needle is carried along by the strand of straw, which is moved forward in the baling channel by the plunger, by a distance which corresponds approximately to the length of the bale of straw to be tied. The lever m is pivoted in the direction of the arrow ν (Fig. 2) in the horizontal plane and the spring w, which engages the lever at point .ar and is attached to the side frame α of the channel, is tensioned. Then the lever m is pressed so far down by the drive that the needle emerges from the bottom of the straw strand. Now the spring w takes effect and pulls the lever m with the needle d in the direction of the arrow y (Fig. 2) back to the original position m ; then the needle is pushed through the straw strand from bottom to top by pivoting the lever m upwards by the drive. Now both ends of the rope are on the upper side of the straw strand so that they can be easily tied into a knot. ■ Claim: Device for guiding the binding agent through the strand of straw from Straw balers by means of a swivel-mounted, yielding in the direction of the strand displaceable needle, characterized in that the needle is articulated at the free end of one below the press channel on one side of this channel mounted arm, which is so inevitably is moved that the needle is successively from top to bottom through the straw strand, below the latter around Ball length in horizontal direction of 6g led down through the straw strand and horizontally by the length of the bale Direction is moved back. 1 sheet of drawings
