Description

Corn harvesters equipped with a heder with dividers, endless chains and a cutting machine, picker and silo cutter machines, devices for threshing cobs and cleaning grain, and devices for transporting stalks, ears, grains, and ground mass are known.

The disadvantage of such combines is that their jaw machine, made in the form of paired counter-vras, rolls, interacting with cobs, damages the cobs and the grain on them.

In the combine, according to the invention, this disadvantage is eliminated by the fact that the chopping unit is made in the form of scissors, cutting off the cob stem, mounted on links of an infinite chain and formed by a process and a rotary knife transverse to the chain, coming closer when lifting the chain and covering a separate the stem, wound into the gap between them in the lower position of the chain by the action of a leaf spring attached end to the wall of the divider opposite to the divider with the chain, before cutting the stem with a cutting by the apparatus.

FIG. 1 shows a combine in longitudinal section; in fig. 2-heading combine, top view; in fig. 3 - part of the header in cross section; in fig. 4 - mast combining unit; in fig. 5 shows a device for cleaning cobs from wrappers and threshing cobs (in cross section).

A combine, for example, a six-speed one, has a heder with dividers /, endless chains 2 and a cutting apparatus 3, a pick-and-tear machine mounted on dividers 1 and endless chains 2, a silo cutter 4, devices for threshing cobs and cleaning grain and transporting adaptations.

Between the dividers / streams are formed for passage along the pair of dividers of the stems cut off by the cutting apparatus, picked up near the butt pair for each row of inclined endless chains 2. The links 5 of the chains of these chains are transverse to the chain (Fig. 4) , which are integral with the links, and 5 knives 6 of a concave shape pivoting at the bases of the processes 5, move closer to the branches 5 when the chain is raised and encompass a single stem passing between them, wound up before cutting the stem into the gap between the knife and the process m in the lower position of the chain.

For winding the cut stem in this gap, a plate spring 7 is applied, attached end to the wall of the divider opposite to the divider carrying the chain with the blades. For controlling the blades 6, they are provided with shanks 8 and 9 of various lengths that cooperate with the guide strips 10 and J1 of the divider. The band} 0 removes the knives 6 from the processes 5 in the lower part of the divider, and the strip 11 brings the knives closer to the processes 5 in the upper part of the divider.

For pulling the stems cut by the cutting unit 3, paired for each row of oppositely rotating shafts 12 and 13 with opposite-lift helical milling, parallel dividers and installed along their lower parts are used through the pick-up unit. The stalks freed from the cobs are transported not shown in figs. 1 heder cheeks into a silo cutter 4 with a puff threshing drum and one deck, and from it enter cheeks 14 unloading for silage. and the screws 16, 17 and 18 are transferred to the distributor 19, feeding the device 20 to release the cobs from the wraps. This device (Fig. 5) is made in the form of a horizontal drum 21, entwined with a grooved steel tape 22 and placed in a cavity formed by rollers 23 covered with rubber corrugated

tubes and parallel to the axis of the drum, along which the cobs displaced by the tape 22 pass from one end of the drum to the other.

Under the outlet of the device 20, there is a switch 24 of a conventional device for threshing grains from cobs and for removing wrap particles. The shastalka grain is cleaned at the grate mill 25 and transferred to the receiving pin 26 of the elevator 27 of the grain breaking hopper 28. The particles of the wrappers and the cobs in the form of a descent from the mill mill 25 are transferred by the tpaHcnopter 29 to the silage cutter 4.

The movement of the combine and its working bodies is carried out from the engine 30.

The dotted line shows the movement of the stems, a dotted line with a point - the movement of the cut off cobs, a dotted line with two points - obelchennogo grain, points - wrappers and particles of rods,

With the help of the puff drum, the stems are cut, chopped and crushed, which contributes to the better absorption of food by animals.

Subject invention

Claims (6)

1. Pneumatic corn harvester equipped with a heder with dividers, endless chains and a cutting machine, pots and grating machines, devices for threshing cobs and grain and devices for transporting stalks, cobs, ground grain, different in that in order to prevent damage to the grain, the coiler is made in the form of scissors, cutting off the stem of the cob, mounted on the links of an endless chain and formed from with a stalk and a rotary knife, coming closer when the chain is raised and covering a separate stem passing between them, wedged between them in the lower position of the chain by the action of a leaf spring attached end to the wall of the divider opposite to the chain divider, before cutting the stem of the stem, using an apparatus. 2. The form of the combine according to claim 1, is different, and with the fact that for pulling the stems, cut by the cutting unit, through the pick-up machine, paired dl are used. each row of oppositely rotating shafts with a screw thread of the opposite lift, parallel dividers and installed along their lower parts. 3. Kombayn on PP. 1 and 2, characterized in that it employs a device for releasing cobs from wrappers, made in the form of a horizontal drum entwined with a chamfer steel tape and placed in cavities formed by rollers covered with corrugated rubber tubes and parallel to the axis of Barb-L 106320 On it, along which the cob, which interact with the edges of the groove of the tape and with the rollers, pass from one end of the drum to the other. 4. In the harvester of claim 3, use the shastalka to thresh the grain from the ears, freed from the wraps and to remove the latter. 5. In a combine according to claim 4, use a grill mill for cleaning the grain and a key for shaking and transferring the stalked cobs (rods) to the silo cutter. 6. The form of the combine according to paragraphs. 1, 2 and 6, using with the use of a puff threshing drum with one deck — from a grain harvester — for shredding the stems by cutting, splitting, and mite making the silage more readily consumable and assimilable as a silo cutter. arj7lctct rttjM rfm (.- cccHj , G ......
