SU107805A1 - Front mounted on tractor header - Google Patents

Description

Frontal mounted front-end header with feed of the mowed weight to the center under the tractor cannot be used as a logger and do not have sufficiently good adaptability to the floor relief.

In the proposed construction of the mounted header, these disadvantages are eliminated due to the hinged suspension of the header, which makes it possible to better adapt to the terrain, and the device for forming a compacted roll in the middle part of the header.

FIG. 1 shows a header view of the “y; in fig. 2 is a plan view.

The platform / is suspended at the center of the plate of special “brackets 2”.

In order to ensure that the finger bar 3 copies the soil relief, there are special extension springs 4, which at one end lean towards the platform I, and the other end towards the hitch frame 5. The springs 4 regulate the pressure of the booms 6 on the soil.

There is a window 7 in the gray and in the platform / for the passage of the bevelled mass. At the ends of the platform, we set / install the mechanisms we swing, their

washers S, which two knives set in an oscillating motion, work simultaneously with them. The knives embrace the top notch of the segments and do not require sharpening during work. The frame of the platform / welded "with a special profile of the boxseed.

For a better separation of the mass, two dividers 9 are attached to platform 1. Platform 1 in operation rests on two floating shoes b, which are adjustable to any height and cut. Canvas chain conveyors 10 have a direction of movement towards the middle of the platform and are driven via a transmiss / platform platform, a chain transmission 11 and a box of 12 leading shafts 13 located along the edges of platform 1.

The eccentric reel 14 is installed above the rezhush, it apparatus of two arms | nah. It has five blades and can rsgul:; rotate both in height and forward ;; backwards The rotation of the reel 14 is carried out in the following classes: 1 by a 15 gear transfer through the shafts of the trapsi AND 16 and countershaft 17. To tension the belts; 1 there are tension rollers 18.

The frame 5 of the header of the header is attached to the spars of the tractor frame.

To preserve the angle of inclination: the platform / independent of the height of the cut-off, there is a one-purpose multi-link mechanism consisting of links 19, 20, 21, and 2. To maintain the inclination angle of the platform / along the permutation of the shoes 6 along the height of the cut of the spawning / wedge to another corresponding hole.

The working units of the header are driven from the tractor's power take-off shaft through a V-belt transmission, a hinged transmission system, boxes with transmission shafts (22, 23, 12 m 13).

The lifting of the plate form is carried out from the hydraulic system and the tractor through a system of t g 24, 21, 19 25. The lifting height of the platform / header in the transport position can be increased to 600 mm.

In order to better pass the roll under the tractor to the header frame, a special casing 26 is designed to form the shaft: K, which excludes the possibility of the tractor wheels.

The proposed design of a row on the ZhRN-3,2 harvester can be applied in the entire northern part of the Soviet Union, including the Baltic States.

For the Southern regions of the Union, the mower KVM-5 should be modified according to the same scheme as ЖРН-3,2, i.e. with the location of the roll - in the middle of the heder platform, c, the heder of the heder platform at the center of the plate , klinoremeynom at (water: m p tyololastnogo reel.

The machine is made semi-weighted, but is prescribed for two tractors MTZ-3-2 (Belarus) and DT-24,

the drive of both MTZ-2 and DT-24 is unified with the ЖРН-3,2 drive.

Reapers can be used for: separate harvesting; harvesting herbal; harvesting buckwheat and legumes; harvesting green corn and sunflower seedlings; Prokose large arrays of zeros.

The simplicity of the design and the greater maneuverability of the harvester makes it possible to use them economically in households when working as a tractor driver.

In reapers, most of the iH mechanisms are standardized: the knife drive swinging shields, the gearbox in the transmission, the gearbox to the drive roller and blades, the V-belt drive on the MTZ-2 and DT-24 tractors, and the reel drive with wrench gear.

Subject invention

1. The front of the tractor to the tractor; an atka consisting of a platform, we, an apparatus, a reel, and conveyors for the cutting mass, is made so that, in order to use the header for the swaths, in the middle part of its platform is made a window for the passage of the mowing mass supplied by the two conveyors to the center of the platform, with the formation of a casing installed at the window.

2. The form of the header but p. 1, about the t | l and I and the m. That, to improve the adaptability of the header "to the relief of the floor, its platform, at the center of gravity, is suspended on the schrävirs (two curved brackets), the upper ends of which and the platform slots are connected parallel to each other with vertical pivoting levers.
