Description

Known plug-in knots for straw presses are made in the form of couplings, washers with cut-outs, etc., driven by gears and designed to twist the wire in order to form the knot.

In the proposed knot knot, a washer is also used to twist the wire, and for the needles, which serve to lead the wire through the slits of the washer, to mix the needles, toothed wires connected to the gears.

In FIG. 1 shows a wire tightening pattern with a washer; FIG. 2 shows the arrangement of the wire feed mechanism, the transfer to the nodes of the piston in the piston and the switching mechanism; FIG. 3-scheme transfer to the puck; FIG. 4-scheme of the inclusion of nodes zatelo.

The knotting or twisting of the assembly is carried out by a toothed washer (fig. 1) as follows. . Nut chickpea across the chamber of the straw press wire, as the hay is fed and the bale is pressed, unwinding the coil 2 (Fig. 3, 1), bends around the bale. At this time, the mechanisms of the nodes are disabled. When the bale is pressed to the appropriate length (the length of the bale is measured with a special wheel not shown in the diagram), the wire feeder is turned on,

driven by large gears 3, one of which is connected to a small cylindrical gear 4. At the end of the roller, the latter is loosely fitted with a bevel gear 5 with a protrusion on the hub. When the bale is measured, the special yoke is rotated by the rocker (not shown in the drawing) to extend the finger 6 (Fig. 4). The latter pushes the finger with the latch 8 out of the rotary sleeve 7. At this time, the fist of firing 9 fits on the big gear 3 and moves the extended finger to the right; the latter, through the lever 70, connects the friction clutch 7 / with the free toothed clutch 72 and the bevel gear 13. Thus, the transfer roller 14 is engaged. The free splined coupling 72 is provided with a counterweight in order to always engage in a certain position.

At the end of the transfer shaft J4, an eccentric faceplate / 5 (Fig. 3) is fitted with a groove, to which one of the gear racks 6 is connected, carrying needles 77. Thanks to the intermediate gear J8 rotating on a stationary finger, the slats move in opposite directions, bearing towards each other needles. The wire, already fascinated by the bale itself in the process of pressing into the needle cuts, bends around the bale. Needles, thanks to screw cuts 72,

rotate in guides 20 to 90 °, slightly twist the wire and feed it into the slots of the washer /, which is stationary. As soon as the needles filed the wire, the tapered pair 2 is turned on and, through the drive roller 22 of the knot knots (Fig. 2) and the tapered pair 23, a large cylindrical gear 24 is transmitted to rotate, transmitting the rotation to the tongue /, during which twisting takes place. At the end of one revolution of the large gear, the knife 25 fixed on it cuts off the knot along the upper plane of the washer. Since the press does not stop, all of the operations described are performed on a portion of the piston's top dead center. The second fist of firing 9 that had come to this time on the big gear turns off the mechanism and thus prepares a press for the second bale. Since the knot is two-sided, the cut-off upper part of the knot goes with the bale, and the lower part is bent by subsequent feeding of hay. Nodes zatel placed in the piston 26.

The subject matter of the invention.
