SU133709A1 - Adaptation to the combine, for example SK-3, for the cleaning of laid leguminous crops - Google Patents

Description

There are known adaptations to self-propelled cayneins, which make it possible to use them in the harvest of laid leguminous crops.

However, the existing machines and devices for harvesting leguminous crops (GNBM-3,2, ЖНУ-3,2, adaptations to ko: baip; m SK-3 and C-4, etc.) do not work satisfactorily on the floor with uneven relief and laid plants. This is explained, first of all, by the inadequate copying of the relief by the cutting apparatus and the lack of its synchronous interaction with the reel.

In the proposed arrangement, a swinging type cutting apparatus with two degrees of freedom is applied to the combine. The cutter annarat and reel are interlocked in such a way that the position of the reel also changes depending on the position of the cutting unit. The suspension of the cutting unit is connected to the hydraulic lifter of the combine with a clutch coupling, which ensures that the entire header is automatically raised or lowered following the raising or lowering of the cutting unit, and at the critical moment, the combine is stopped. This eliminates the disadvantages of the known devices for harvesting lodged crops.

The constructive scheme of attaching to the SK-3 combine for harvesting laid leguminous crops includes the following elements:

1) the cutting device of the swinging type, established instead of the usual; 2) telescopic lifters; 3) passive zero dividers with spring-loaded skid; 4) eccentric reel; 5) Bloter Slider for synchronous interaction of the reel with the cutting unit; 6) a device for automatic copying of the relief by the header of the combine; 7) the number of working bodies.

FIG. 1 shows the device installed on the head of the SK-3 combine (side view); in fig. 2 - input to the cutting apparatus of the device.

No. i 33709-2 -

The cutter / is mounted on the header instead of the usual n consists of a finger bar (Fig. 1) with shortened fingers and lifters 2 set every two fingers. The finger bar is suspended under the heder - with the help of skis 3 on special hinged hangers 4, which hold the finger bar from lateral forces. The hangers 4 are deflected by the stoppers 5 by 15 ° and allow the cutting apparatus to lift up and lean back along the swing swing path.

To remove the cut mass from the cutting unit to the header, a grid 6 is installed, hinged at one end to the finger bar, and the other end lying loosely on the header.

The passive action field dividers include a body 7 with a tapered end, a spring-loaded hinged track 8, an arcuate bar 9, and a support 10 a track in the form of a pair of curved telescopic tubes with a spring providing the required pressure of the track to the ground.

The locking device for synchronous interaction of the reel and the cutting unit consists of a rocker arm 11, hinged on the sides of the dividers of the combine, to the front end of which a hydraulic cylinder 12 is attached. The reel attachment rests on the hydraulic cylinder. To increase the travel, the reel is extended by 120 mm shoulders of the supports 13.

The rear end of the rocker arm // is connected by a length 14 adjustable throttle to the suspension of the cutting unit, as a result of which, when the machine retracts backward and upward, the reel rises up and moves backward by the same amount.

A device for automatic copying of the soil by the combine header is a cable loop 15 connecting one of the suspensions of the cutting unit and the handle 16 of the hydraulic lifting system of the header, which has a regulating spring 17. When the cutting unit is deflected back and weakened, the tension of the cable works hydraulic system (with the help of a spring) and the heder rises until the finger bar is lowered to the initial position and the cable is tensioned. Pull the cable back on the handle and lower the header of the combine. A similar connection is made with the clutch coupling of the combine harvester.

The blade of the cutting apparatus is driven from the swing angle bracket 18 (Fig. 2) of the combine by means of a rod 19 and a carrier of a rocking chair 20. A connecting rod 19 is connected with a carrier 20 by means of a spherical bolt with shock-absorbing rubber washers.

The rocking carrier is inserted at one end into the thrust frame 21 of the knife between the two rollers, and the other end with a rubber hinge is attached to the hanger 22, which is similar in design to the hinges of the cutting unit. To soften the shock load on the knife, the carrier 20 has a shock-absorbing spring 23. The front end of the rocker transfers the vertical loads not to the knife frame and the clamp, but to the guide plate, which has shims.

Telescopic lifters are equipped with dust collectors and have an adjusting bolt to adjust the angle of inclination.
