(54) FIELD DIVIDER OF AGRICULTURAL CUTTING MACHINE (57) This invention relates to agricultural machinery. The purpose of the invention is to reduce losses by increasing the reliability of separation of laid and tangled stems. The field divider of an agricultural harvester contains a hollow body made of hinged lower 1 and upper 2 cascades. Inside the housing there is an actuator including an eccentric 3, a connecting rod 4 and a yoke 5. The ball is installed last

One end of the rocker arm 5 is pivotally connected to the connecting rod 4, and the lower stage 1 is suspended to its other end. When the machine is operated together with the rocker arm 5, the upper stage 2 is rocked. Swinging the latter causes the lower stage 1 to move,

The invention relates to agricultural machinery, mainly field field dividers for mowing grain, leguminous crops and rice, and can be used for harvesting other crops having fallen and entangled vegetal mass.

The purpose of the invention is to reduce yield losses by increasing the reliability of the separation of laid and entangled stems.

FIG. 1 shows a cleaning machine with the proposed divider, right view; in fig. 2 - field divider, right view; in fig. 3 - the same plan view; in fig. 4 shows section A-A in FIG. 2; in fig. 5 is a pattern for copying the relief floor divider.

The field divider consists of the lower 1 and upper 2 stages forming the hollow body. Inside the housing there is a drive including an eccentric 3, a connecting rod 4 and a yoke 5. The latter is installed spherically on an axis rigidly fixed on the frame of the machine's b (for example, on the end of the header front bar), with the possibility of swinging in a longitudinal-vertical plane. One end of the rocker arm 5 is pivotally connected to the connecting rod 4, and the other end is pivotally suspended by means of lugs at the lower cascade 1, while its center of gravity is located below the point of suspension, and the nose part is resting on the ground. The upper cascade 2 is hollow and covers the yoke of 5, which is connected to it together. Thus, the lower cascade 1 is pivotally connected not only to the rocker 5, but also to the upper cascade 2. The crank 4 is located inside the hollow side 7, which serves, for example, to prevent the planting of long and fallen plant stems on a swath conveyor (not shown). The lower cascade 1 is also hollow and has a plate 8 fixed inside, which serves as an acceleration, lifts the lodged stems. At the same time, the angle between the horizontal and upper edges of the cascade 1 increases and decreases at the end of the phase, which provides a preliminary separation of the stems. Cascade 2 performs the final separation of the stems. 4 h. n. f-ly, 5 ill.

retainer of its lower position. A frame 10 is attached to the front bar of the frame b using a Z-shaped bracket 9, which, like the plate 8, is located inside cascade 1. Cascade 1 is connected to the bracket 9 by means of a spring 11.

The proposed divider works as follows.

The rotation of the eccentric 3 causes

oscillations of the connecting rod 4, which drives the beam 5, swinging in a longitudinal-vertical plane relative to the axis fixed on the frame 6. Together with the yoke 5, the rigidly connected

the upper cascade 2 with it. The swing of the latter causes the lower cascade 1 pivotally connected to it to be reciprocating, which is constantly in contact with the nasal

part with the surface of the earth, i.e. slides on it.

In the phase of penetration into the plant mass, the lower cascade 1 receives an acceleration coinciding in direction with the translational speed of the machine and lifts the laid stems. In this case, at the beginning of the movement, the angle between the horizontal and the upper edge of the lower cascade 1 increases, and at the end of the introduction phase

decreases. Thus, the entangled and laid down vegetable mass initially condenses somewhat, strung on the lower cascade 1 and rises, thus weakening the bonds.

between mixed stalks, i.e. their preliminary separation.

In the separation phase, with the reverse (relative to the direction of movement of the machine) movement of the lower cascade 1, a raised and previously divided portion of vegetable mass moves down from the lower cascade 1 and enters the upper cascade 2, which throws it up with a working edge and produces the final separation of entangled stems.

During the working stroke of the machine, the lower cascade 1 is constantly pressed to the ground by the action of the spring 11, thereby introducing it into the lodged vegetable mass rather than sliding on top of it. When translating (lifting) the machine into the transport position, the lower cascade 1 lowers cushioning the suspension point to the lowest position when plate 8 is in contact with roller 10. If the transmission (not shown) of the machine is not turned off, plate 8 rolls over roller 10, ensuring that the divider operates in idle mode, for example, and turn the machine at the end of the rut.
