SU1366097A1 - Header for grain combine harvester - Google Patents

Description

The invention relates to agricultural machinery. The purpose of the invention is the improvement of safety: reapers during transportation of the combine

over long distances. The reaping part of the combine harvester includes a header platform with a carrier cue 2, a trimming mechanism and an inclined chamber. The balancing mechanism includes a swivel lever 5, made two shoulders. The lower arm 7 of the lever 5 has an inner 8 and an outer 9 support surfaces. On the carrier beam 2 mounted copy limiter 10 and latch 1.1. Between them is placed the lower arm 7 of the lever 5. When transporting the combine, the arm 7 of the lever 5 with surface 8 abuts against the copy limiter 10, and with surface 9 mates with the axis of the retainer 11. The coupling of the lower arm 7 of the lever 5 along two surfaces ensures reliable fixation of the header relative to the inclined chamber. This, in turn, eliminates breakage and destruction of elements of the working bodies of the header. 5 il. ⁷

The purpose of the invention is to increase the safety of the header when transporting the combine over long distances.

The reaping part of the combine includes a reaper platform 1 with a carrier beam 2, a spring balance mechanism 3 and an inclined chamber 4.

The balancing mechanism 3 ′ includes a pivot arm 5 and a suspension 6, which is pivotally connected to the pivot arm 5 at one end and the pivot camera 4 ′ to the other pivot (in Fig. 2 only the left side is shown; 5 mirror image). The swivel lever 5 is made two shoulders, the lower shoulder 7 it has an internal 8. and external) 9 supporting surfaces. On . ³⁰ non-sheer beam 2 is set up limiter 10, being a stop for the inner surface 8 of the lower arm 7, the pivot arm 5.

On carrier balker 2, in the zone of movement 35 of the lower arm 7 of the lever 5, a clamp 11 is mounted, which is made in the form of two brackets 12 and 13 with holes 14 welded to the plate 15 • and spaced apart on the sides relative to the plane of rotation of the rotary lever 5 and the axis 16, inserted into the holes 14. The lower arm 7 of the lever 5 is placed between the copy limiter 10 and the axis 16 of the latch 11 45

with the possibility of interfacing its outer surface 9 with the axis 16, and the inner 8 with a copy limiter 10. From falling out, the axis 16 is held by a quick-detachable pin 17, which 50 is inserted with a pointed end 18 into the aligned holes in the ring Ϊ9 welded to the bracket 13 from the outside and axis. 16, while the other end 20 encloses ring 19 and sets it to fire for it due to a spring loaded belt. On axis 16 a restrictive washer 21 is welded, which determines the position of axis 16 in brackets 12

and 13 (until the washer 21 stops against the ring 19), thereby facilitating the alignment of the holes in the axis 16 and the ring 19 for the quick-release pin 17.

For ease of use and to avoid loss, the quick-release pin 17 is permanently fixed with the help of a durable thread 22 on the handle of the axis 16. During the work of the header 1, the axis 16 is in a specially designed place — inserted into the holes of the U-shaped stand 23 of the header 1 and fixed from dropping with cotter pin 17. ·

The work is as follows.

For long journeys of a combine with a mounted header 1, the latter must be moved to the transport position, i.e. fix the header platform -1 rigidly with the inclined chamber 4. To do this, using hydraulic cylinders (not shown) raise the harvesting part relative to the upper shaft of the inclined chamber 4, pivotally mounted on the front legs of the thresher (not shown), by the full stroke of the hydraulic cylinder rod, while the header platform 1 occupies the lower limit of copying, and the pivoting levers 5 of the trimming mechanism 3 with the inner surfaces 8 abut against the reproduction limiter 10. With this position of the pivoting lever 5, the axis 16 is freely mounted pours into the holes 14 of the brackets 12 and 13 behind the outer bearing surface 9 of the lower arm 7 of the lever 5 and is secured against falling out with the linch pin 17.

The mating of the outer bearing surface 9 of the lever 5 with the axis 16 prevents the header 1 from moving upwards, i.e. reliable fixation of the header 1 relative to the inclined chamber 4 is ensured, since the lower arm 7 of the lever 5 mates on two surfaces: the inner 8 - with the copy limiter, and the outer 9 with the axis 16. Such fixation eliminates breakage, increased wear of the elements; working bodies of the header, i.e. its safety increases.
