Description

(54) HEADER

one

The invention relates to agricultural machinery, in particular, to devices for mechanized harvesting of agricultural crops, preferably for mowing unevenly maturing and easy-flowing grafts of forage grasses.

The known header, mainly for grass testicles, contains a reel, a cutting unit, a multi-belt cross conveyor, a longitudinal conveyor, suction air ducts connected to the cyclone and the fan 1.

A disadvantage of the known header is that in the process of mowing there are losses of seed due to the ingested grain between the transverse and longitudinal conveyors, as well as due to the low separation of seeds on the longitudinal conveyor.

The purpose of the invention is to reduce seed losses by selecting selected seeds from a cross conveyor.

The goal is achieved by the fact that the header, containing a cutting unit, a multi-band belt transverse conveyor, suction air ducts connected to the cyclone and a fan, has a bottom with transverse duo-pitch protruded, and the ribbon of each stream of the transverse conveyor is made of two longitudinal parts connected sharnarno, and provided with brushes, which are fixed with an interval on its edges, and the intake parts of the suction air ducts are placed between the projections of the bottom. 10 Above the hinges of the belts there are visors made of elastic material.

There are guides on the bottom of the header above the brushes.

FIG. 1 shows a header, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The harvester contains a cutting machine 1, a reel 2, a reversing platform 3 with a transverse multi-rifle l "1 point tranporter. The bottom of the platform 3 of the header has 20 transverse duo-pitch protrusions on which the strips 4 are located, each of which is made of two parts, connected in the longitudinal direction by hinges 5, on which the supporting strips 6 are mounted, of which consists of. two halves with the possibility of forming a single surface and in the joints of the two halves of the strips 6, protective visors 7 are made of elastic material and each part of the tape 4 is provided with feeding elements 8 with brushes mounted on the strips 4 with an interval. At the ends of the platform, fixed, longitudinally located suction lines 9 and 10 are installed, made in the form of a seed chute, connected by means of air ducts 11 through a fan 12 to a cyclone 13. An automatic regulator 14 serves to switch the suction air flow from one tray to another. and for the efficiency of swathing of the belts, guides 15 are installed on the bottom of the platform at its two ends. Between the two projections, grooves 16 are formed.

Reaper works as follows.

The harvester is driven by carriage. During the first pass of the plant, the plants are mowed and fed to the reversing platform 3. In the gap between two longitudinally located suction pipes 9 and 10, the swath formers 4 of each stream run onto the projections of the bottom of the platform 3 and thanks to the guides 15 mounted on the bottom on both sides of the platform 3, acquire from a flat form a gable with a protrusion upward, due to the hinge connection of the two halves of each tape 4 and the nesushih slats 6, and then the bevelled mass passes over the longitudinally located suck pipe 9 and is placed in the roll. At the same time, the seeds of plants threshed under the action of the reel 2 of the cutting apparatus 1 and the ribbons 4 slide along the swath-like surface of the belt 4 and are separated from the canted mass, then fall into the transverse grooves 16 formed between the pairs of belts 4 on the bottom of the platform 3. From the transverse seams of the grooves 16, the seeds, by means of brushes 8, moving along the bottom of the platform 3 as the swathing strips 4 move, are fed to a longitudinally located suction pipe 9, from which the seeds are transported by the air flow generated blower 12 through air conduits 11 into the cyclone 13. In the second pass through the field unit reversive platform 3 is moved to the left, is performed automatically switching regulator 14. Automatic switching controller 14 changes the direction of the suction air flow to the pipeline 10.

Harvested seeds are harvested and transported as in the first

passage, but already at the reverse movement of the swath belts 4.

The application of the invention makes it possible to reduce the losses of threshed seeds behind the header, simplifies the design scheme

harvester and increases its reliability and efficiency of use of the harvester for separate harvesting of testes of pasture grasses.
