Description

The present invention relates to self-propelled type agricultural harvesters.

Self-propelled combines with front headers supported on shoes are known.

Also known harvesters mounted type with two threshers.

Distinctive design features of the proposed combine the following:

a) in order to increase the productivity of the thresher without increasing the size of the individual parts of the working parts, it is made in the form of two sections mounted in one common frame;

b) in order to automatically copy the relief of the floor and reduce the size of the pyrine during transportation of the combine, as well as to improve the supply of stems to the cutting unit on uneven terrain, the heder and the power saw are section-hinged, and the central case of the hedera is hinged on the chassis frame parts the two side wings are hinged with the central one, and the reel of the wings is silt; e; c; the body is equipped with a hinged fixing of the rays on the disks, and the blades on the rays. At the field ends, the side sections of the reel rest on the support bearings slidably in the bearings when the wings are raised and lowered relative to the center section;

c) in order to uniformly fill the entire volume of the bunker with grain, without the participation of the operating personnel, a fan wing was used in combination with a visor and guide ribs, and for unloading the bunker-device of a wing with a pipeline and a pivotally suspended sleeve.

FIG. 1 shows a combine (general view); in fig. 2-header and position schemes; in fig. 3-reel; in fig. 4-scheme of filling the hopper.

The combine consists of a self-propelled chassis 1 (fig.) On which are motivated: a two-section thresher 2, a floating header 3. a bunker 4 n reel 5 (fig. 3).

In front of the combine, there is a motor with a main transfer case for driving the driving wheels and mechanisms of the combine, as well as all the mechanisms for controlling the running gear.

The front-hinged, articulated, floating, co-zero relief consists of a six-body case 6 (Fig. 1), 1 pivotally suspended from the chassis frame brackets, two wings 7 and 8, a ball connected to the central case and having an independent suspension.

Balancing of the central body in different positions is achieved by changing the shoulder, and which acts on the tension of the spring unit. Increasing the null compensates for a decrease in tension and the ladies as the header is raised, the degree of balance of the hull remains constant. The wing of the header hangs on cable 9 (Fig. 2) connected to the balancer, Ayuki-B mechanism. Prg g; raising and lowering the wings of the pillars 10 and 11 1; 5; from the angle of the pin of the tension of the spring tension line, the eaMijiM shoulder action -1 tension. These achieve a constant equilibrium moment, providing iodinem and lowering of the wings, when it is effective: ielpom pressure 1 and ba ba pmaki 12 (php. I) and 13. The pressure pa baimaki is regulated by pulling the equilibrium x 1 gun to limits, ensuring smooth copy topography floor. Controlling the raising and lowering of the central body of the header and interlocking with the cable 14 with the aid of the control lever and, acting on the usual lifting mechanism, is Mechanical or hydraulic. Put; 1e. The image in FIG. 2, corresponds to the extreme upper number of headers during field transnorting of the combine.

For installation of the combine in transport position on country roads and. The wing transport is lifted up from the rear by inclining to the central body on which they are fastened.

The reel has a secondary section 15 (fig. 3), supported by the central body of the header, and two ceiau-in six wings of the header. The wing reel is connected with: from 1 tal: goy to ki; -: to her and; a13 - irio, g at field ends supported on iodine bearings:, erezk 17, having the ability to slide in bearings when lowering relative to the central body. For installation in the trans-port position, the side sections of the reel are engraved, folded and delivered on the threshing body.

The folding reel has a reel that has a device on it. Rays 18 (Fig. 3) are fixed on the disks in an angular manner. Lonasti 19 is also sharpened on rays. The rigidity of the reel is achieved by means of a muff 20, fixing the extension of the rays 21 at the same time. To set it into the transport position, the muff h is released and shifted along the shaft.

Between the elevator sections of the thresher, a wing 22 is installed (Fig. 4), on the shaft of which on both sides there are short spirals 23 (right and left) feeding grain to the center of the wing coming from the elevators. Krylak feeds grain into the bunker. The division of the total flow of the earth into individual streams, with the whole) to the) uniform filling of the entire bunker area, without accessibility; Already 1 person is performed with goats 24 with 1 direction 1 and edges 25.

The grain is unloaded from the hopper by means of the screw 26 located along the bunker and the wing 27 with the inclined pipeline 28 and the sleeve 29 pivotally suspended thereto.

Claims (5)

1. Self-propelled combine harvester with front header, threshing machine, reel, grain elevators and grain hopper, thanks to the fact that, with an increase in thresher productivity without increasing individual working parts, it is made in two sections mounted in in one common frame, and for the purpose of adapting the heder to the relief of the floor, it is made floating, articulated, with a balanced central body and wings, which automatically copy the relief of the floor in the longitudinal and transverse directions at a given height for, adjustable installation copying bai1makov. 2. The form of the combine under item 1, characterized in that, in order to automatically copy the topography of the floor and reduce the size along the width during transportation of the combine, as well as improving the approach of the stems to the apparatus on uneven terrain, the heder and reel are sectional -sharinry. moreover, the neutral body of the header is pivotally iodven. on the pgasi frame brackets, two lateral wings, having an independent balanced suspension for automatic copying of the relief field, are spherically connected to the central body of the header, and the lateral sections of the reel have skidding, hinged beam fixing on the disks, and the blades to the rays. 3. Forl and combine performance according to claims. 1 and 2, from the point that the side sections of the reel rest on the bearings of the supports with the possibility of sliding in the bearings when raising and lowering the wings relative to the central section. 4. The form of the combine but also. 1, characterized in that, in order to maintain a constant degree of balancing of the central body and wings of the header at their different positions and thereby facilitating control, the central body of the header is balanced by means of a spring unit, long and short cables and a lever, due to changes of the shoulder between the short cable and the pnp-: aha axis, and the balancing of the side wings of the header that are suspended from the central i opny, connected with the counterbalancing mechanism of the latter. This is due to the fact that when the wing is raised and lowered, the thrust cable strut changes the angle of inclination relative to the line of tension of the springs, and thus the shoulder of the action of tension. 5. The form of the combine according to claim 1, characterized in that. that, in order to uniformly fill the entire volume of the bunker and car body with grain without the attendant personnel, the fan wing in combination with a visor and guide ribs was used to fill the bunker, and for unloading grain the wing was combined with a pipeline and a pivotally suspended sleeve. ,,. u || r p :: 4, , .41; - J.e-i: : ....-.- X f YYS /.
