Abstract

1. A HEADER, containing a frame, copying shoes, between which a cutting bar with a finger bar is installed, is located above the boiler’s suction nozzle of the fan, which, in order to reduce grain losses and increase the efficiency of work, under the finger one by means of hinged rolls mounted packer roller, behind which the tangent to him, ustanovovlen apron. 2. The harvester according to claim 1, of which is the fact that the front wall of the suction nozzle is bent upwards and provided with a mechanism for changing its height.

The invention relates to agricultural machinery and can be used for harvesting grain crops and other similar stem plants.

Known reapers, containing shoes and fingers with wedge knives between them and the feeding mechanism of plants I made in the form of a reel and devices for lifting laid plants, made in the form of various mechanical devices 1.

The disadvantage of these headers is the complexity and high material consumption of the reel, and the blows of the reel rake knock the grain out of the ear, which leads to significant losses. Lifting devices are also complex and high material intensity, and also low reliability due to low position over the soil, often leading to their breakage, their impact action also leads to significant grain losses.

Closest to the proposed harvester, containing a frame, copying shoes, between which a cutting device with a finger bar is installed, above which is located the suction nozzle of the fan 2.

Its disadvantage is the inefficiency of the work and the loss of grain due to the all-round absorption of air and plants.

The purpose of the invention is to reduce grain losses and increase operational efficiency.

This goal is achieved in that a press roller is mounted in the cutter under the finger bar by means of articulated leads, behind which an apron is installed relative to it, while the front wall of the suction nozzle is bent upward and equipped with a mechanism from its height.

In addition, the fan blades on the suction side of the fan are installed with a gap to the fan casing.

FIG. 1 shows the header, general view; in fig. 2 - the same, side view, in section; in fig. 3 - the same, top view.

The harvester consists of outer shoes 1, between which fingers 3 with wedge knives 4 fixed on the finger bar 2 are fixed in a row on the back 5. A flat-gap nozzle b is located above fingers 3 with knives 4, the back wall 7 of which is hermetically fixed on the finger bar 2, and its front wall 8 at the level of the fingers 3 along the radius is bent upward in the form of a visor 9. On top of the nozzle b are two symmetrical

connected to two paired fans 10, the impellers 11 of which, for the purpose of eliminating stalk sticking to them, are made with a gap 12 from the entrance of the fan housing 10. The fans 10 have discharge tangential nozzles 13 that go into the lifting channel 14, in which it is possible to install the lattice 0 of the stem conveyor 15 and the belt or ladle conveyor 16. Behind the finger bar 2, a roller 17 is installed on the articulated carrier, and a valve is suspended on the articulated suspension, ( artuk) 18. The impeller shaft 11 is provided with fans 10 drive sprocket 19 with a chain drive backrest 5 20.Privod wedge knife 4 is arranged in a box 21.

The front wall 8 of the nozzle device b is configured to vary the height, for which it can be equipped with adjustable thrusts or, in particular, a hydraulic cylinder 22 and an articulated suspension 23, while the lateral sides of the wall 8 .. are overlapped with outer bladders.

Reaper works as follows.

0 When working on laid grain cereals, the header is set in the opposite direction to the laid cTee. By the hydraulic cylinder 22, the front wall 8 of the nozzle 6 is lowered with its

5 visors 9 to the level of fallen ears. The drive of the combine or tractor through the chain drive 20 and the sprocket 19 unwinds the impellers 11 of the fans 10, thereby establishing a powerful suction air flow in the nozzle b, which is drawn only from under the visor 9 of the front shear 8 of the nozzle 6, since its side the cross section is overlapped by the outer shoes 1, the rear air is blocked by the roller 17 with an apron 18. When the header moves forward, the visor 9 moves over the lying ears of plants, and if there is a possibility of some excess height of the ear of the lower point of the visor 9, it voim slope crushes them under SEB captures their air flow and draws in the nozzle used, and thereby raising the

5 straighten their stems. The fingers 3 are located on the stalks of the plants, which are already practically beginning to level off not only under the action of the upward air flow, but also under the action of

0 of their physical restoration by the rear wall of the 7 conjia 6, are fed to the wedge-cutting knives 4 and are cut, while the rise of the front plants determines the conditions for lifting the following plants on their stems

Claims (2)

1. HEADER, containing a frame, copying shoes, between which a cutting device with a finger bar is installed, above which there is a suction pipe of the fan, distinguished by the fact that, in order to reduce grain losses and increase work efficiency, under the finger bar by means of articulated leashes a packer roller is mounted, after which an apron is installed tangentially to it. 2. The reaper according to claim 1, with a l a h Join in that the front wall of the suction pipe is bent up and equipped with a mechanism for changing the height of its position.
