Further, the device also comprises a driven gear 3 arranged on the periphery of the square bale discharging channel 1 and a driving gear 2 which is meshed with the driven gear 3 and is used for driving the driven gear 3 to rotate;
and a net rope shaft wound with a bundling net rope is fixed on the driven gear 3 and is positioned on the outer side of the net breaking mechanism.
The process of using the wire breaking mechanism of the embodiment to break the wire of the square straw baler is as follows:
in the initial state, the pulling net plate 9 presses the rope end of the bundling net rope on the pressing net plate 12.
The square bale bundling machine operates, and the square bale is discharged from square bale discharging channel 1, and at this moment, driving gear 2 drives driven gear 3 and is rotatory in square bale discharging channel 1 periphery, and the bundling net twine of net twine axle is outside at the square bale (this part is bundled and is the conventional structure of current square bale bundling machine, and this no longer gives details again). When the aromatic grass bundles are bundled by the bundling net rope for the penultimate circle, the driven gear 3 stops rotating, at the moment, the hydraulic rod 5 retracts into the hydraulic cylinder 4, the hydraulic rod 5 drives the connecting seat 6 to move forwards, then the push-pull rod 7 fixed on the connecting seat 6 slides forwards along the limiting sleeve 8, the net pulling plate 9 at the end part of the push-pull rod 7 moves away from the net pressing plate 12, when the net pulling plate 9 moves to the front side of the net rope shaft, the hydraulic cylinder 4 stops, then the driving gear 2 drives the driven gear 3 to rotate again, the bundling net rope bundles the aromatic grass bundles for the last circle, and the push-pull rod 7 is wound in the last circle of bundling net rope; the hydraulic cylinder 4 is started again, the hydraulic rod 5 extends from the hydraulic cylinder 4, the hydraulic rod 5 drives the connecting seat 6 to move backwards, then the push-pull rod 7 fixed on the connecting seat 6 slides backwards along the limiting sleeve 8, the net pulling plate 9 at the end part of the push-pull rod 7 pulls the last circle of bundling net ropes to be pressed against the net pressing plate 12, the hydraulic motor 10 is started to drive the rotary cutter blade 13 to rotate while the push-pull rod 7 pulls the bundling net ropes to move backwards, the bundling net ropes pulled by the net pulling plate 9 are cut off by the rotary cutter blade 13, rope heads of the bundling net ropes are pressed at the net pressing plate 12 by the net pressing plate 12, the first bundling and net cutting of the bundle of grass are completed, and the bundling and net cutting processes are repeated along with the continuous operation of the square bundling machine.
Specifically, the start and stop of the hydraulic motor 10, the hydraulic cylinder 4 and the driving gear 2 can be controlled by a PLC program, the PLC program sends a starting signal to drive the driving motor driving the driving gear 2 to rotate, the rotating speed of the driving motor is assumed to be w, and the radius of the driven gear 3 is r1Radius of the driving gear 2 is r2The net ropes on the driven gear 3 bundle the other bales for m circles, the running time of the driving motor is h, and the driven gear 3 is meshed with the driving gear 2 for transmission when the net ropes bundle the aromatic bales for m-1 circles, and the total stroke of the driven gear 3 is the same as that of the driving gear 2, namely 2 pi r1（m-1）=2πr2wh, so h = r1（m-1）/r2w, collecting the rotation time of the drive motor as h = r in the PLC program1（m-1）/r2when w is detected, a delay signal is sent out to control the driving motor to stop and the hydraulic rod 5 to start to contract, when the hydraulic rod 5 drives the screen pulling plate 9 to move to the front side of the net rope shaft within the delay time, after the delay time is over, the PLC controls the hydraulic rod 5 to stop acting, and the driving motor is started again for r time1/r2w, the last round of bundle of aromatic grass is tied to the bundling net rope promptly, PLC sends delay signal once more, driving motor stall, hydraulic motor 10 starts to drive rotary blade 13 and rotates, hydraulic stem 5 drives and draws otter board 9 to move to and draws the bundling net rope of last round and press otter board 12 department in the delay time, accomplish rotary blade 13 and break the net, the fag end of bundling net rope is pressed at otter board 12 department by pressing otter board 12 simultaneously, after the delay time, PLC control hydraulic stem 5 and hydraulic motor 10 stop motion, and send control signal and make the driving gear 2 pivoted driving motor start, repeat above-mentioned process, thereby realize PLC program control.
Compared with the traditional cutting knife which only depends on jacking to cut the net rope, the utility model cuts off the bundling net rope by rotating the rotary blade 13 driven by the hydraulic motor 10, the net is broken quickly and thoroughly, and the problem that the net rope is stretched and twined is avoided; the net rope end is pressed again after the net is broken and reset, so that the continuous operation of the square straw bundling machine is facilitated.
