(5) CHILDREN'S DECK

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to decks of threshing devices.

A decal of a threshing device is known, comprising smooth cylindrical cylinders, which are installed along a cylindrical surface.

The closest technical solution to the proposed decal is a threshing device containing Vadians with spiral winding, a receiving chamber and a drive 2.

A disadvantage of the known device is the incomplete threshing and separation of the grain. In addition, scraps of stalks and large impurities pass along with the grain between the rollers, nepeiruja a sieve of the first cleaning of the combine.

The purpose of the invention is to increase the threshing intensity, improve grain separation and reduce the contamination of the grain heap with large impurities.

The goal is achieved by the fact that the deck rolls are made in the form of truncated cones and are installed along the forming truncated cone with overlapping spiral coils on adjacent rollers, the smaller bases of the truncated deck cones and rollers are located on the side of the receiving chamber.

In addition, the drive rollers made planetary.

FIG. 1 - the deck is shown, general view; in fig. 2 - the same cross section; Fig 3 is the same, view A in Fig. 2; in fig. k is the same, section bb in fig. 3; in fig. 5 is the same, the housing drive in FIG. 6 - the same, drive rollers.

The planetary deck includes a deck 1 case, rollers 2, bearings 3

Claims (2)

20 deck 1 cases, 4 rollers front bearings, receiving chamber 5, 1 deck housing 6 drive, 7 rollers rear bearings, 8 rollers drive 2 stalk diverting chamber 9. The deck with rolls covers the threshing drum 10. The deck 1 case is made in the form of a truncated the cone, on the smaller and larger bases of which the receiving 5 and stem stalk chambers 9, as well as the front 4 and rear 7 roller bearings 2 are mounted, and the bases of the deck 1 are connected by jumpers 1 mounted above each roller. The drive 6 of the deck 1 case includes the slave 12 and the lead 13 multi-rifle drive pulleys and V-belts 1. The pulley 12 is mounted on a smaller Shem base of the deck 1 case. The rolls, decks 2 of the deck are made in the form of truncated cones, the axes of which are installed along the forming truncated cone so that its smaller bases and smaller bases of the rollers are facing the stem receiving chamber 5 and between the rollers 2 and the drum 10 there is a gap that decreases towards the stem diverting chamber 9. Rollers 2 have spiral windings 15. In this case, in the plane of the axes of adjacent rollers, the turns of one roller are located between the turns of the other with the gap between the rollers overlapping. The drive 8 of the rollers 2 consists of a fixed solar wheel 16 with internal gearing and satellites 17 mounted on the shafts 18 of the rollers 2. The device operates as follows. The deck rotates in the direction of rotation of the drum 10, the rollers 2 rotate in the opposite direction. At the same time, the layer of stem mass coming from the receiving chamber 5 into the space between the drum 10 and the rolls 2 of the deck, moves in the direction of rotation of the threshing drum and is pereterat due to the difference in the circumferential speeds of the deck, the drum 10 and the rolls 2. Coils of spiral windings 15 on the rolls 2 layer It is swept and moved along the axis of the drum 10 to the stalk collecting chamber 9. Under the action of centrifugal forces, the milled grains are separated from the stem layer towards the deck, passing through the grating in the gaps between the rollers 2 formed in dipper sleep 4 eral navivok 15 and then pass through the window between the webs 11 of the housing. In this case, the coils of winding 15 on adjacent rollers 2, rotating in one direction and overlapping each other, prevent passage along with the grain of stem scraps and large impurities between rollers 2 and advances them to the exit. The intensity of threshing and grain separation is achieved by the fact that the turns of the spiral windings 15 displaced from the roller to the roller on the working surface of the deck are rubbed and combed off the stem layer over the entire working surface of the drum. At the same time, the threshing intensity increases along the stems from the receiving chamber by increasing the diameters and peripheral speeds of the roller deck, which increases the completeness of the threshing of hard-to-separate grains. In comparison with the prototype, the weediness of the grain pile is reduced due to the overlapping of the turns between adjacent rollers, preventing the passage of stem pieces and large impurities on the sieve. Claim 1. Deka threshing device containing rollers with spiral windings, receiving chamber and drive, characterized in that, in order to increase the intensity of threshing, improve grain separation and reduce the contamination of the grain heap with large impurities, the rollers are made in the form of truncated cones and installed along the truncated cone forming overlapping spiral windings on adjacent rollers, the smaller bases of the truncated cones of the deck and the rollers are located on the side of the receiving chamber. 2. The deck according to Claim 1, characterized in that the drive of the rollers is made planetary. Sources of information taken into account during the examination 1.
