Description

(5) ROTARY COMBINE

one

The invention relates to agricultural machinery, in particular rotary combines for harvesting agricultural crops.

A rotary combine is known that contains a support frame on a wheel track, a pick-up, a feed conveyor, behind which is a casing placed in a side outlet window, a cross drum with trellis tamping, means for connecting the combine with an energy source l.

The performance of this combine is not high enough.

The invention invention is performance improvement.

This goal is achieved by the fact that the transverse drum is cylindrical with blades, and an additional cylindrical bladed drum with lattice concave attached to the casing with side entry windows is installed. than to the inner surface of the shells are attached guide fins for

transporting the grain mass with the main drum from its center to the ends, and the additional one from the ends to the central exit window, while

5 side windows of covers are interconnected by channels.

FIG. 1 shows a rotary combine, side view with a partial section; in fig. 2 - the same plan view; on

U FIG. 3 - the same, side view, a variant with a screw instead of the second drum; in fig. “- the same view in the plan.

On the support frame 1, mounted on a pair of wheels 2, there is a tow

13 is a device 3 with a coupling hook k, by means of which the device (rotary combine) can be attached to the vehicle (tractor).

Claims (1)

20 The tractor, through the power take-off shaft, also transmits energy to the drive shaft 5, located just above the chain node, which is connected to gearbox 7 via universal joint 6 and across the supporting frame 1 is a forward rotating lamp drum, indicated as a whole by the position 8, and a rear rotating blade drum, generally designated 9, or an auger, with both nodes adjacent to each other. A conventional culture unit (selection), designated 10, is mounted on the front of the support frame. The inclined conveyor 11, mounted behind the pick-up 10, is connected to the casing 12 of the rotating blade drum 8 and is located centrally between its ends. The drum 8 has blades located opposite on each side and installed with the possibility of adjustment. On the inner surface of the casing 12, fixed ribs 13 are directed in opposite directions from the axial center line so that they, together with the beater blades, divide the grain crop entering the drum into two parts, the first of which moves towards one butt and the second moves towards the other. Butt N and 1 are placed under the drum 8 and drum 9 (or auger). There is a straw walker with 16 and a wall 17 behind the drum 9 (or auger). The casing 12 of the drum 8 is connected to channels 18 the casing 19 is rotating Its blade drum 9 (or auger), which is similar in design to a rotating blade drum 8, except that the beater spiral blades and fixed ribs 13 are inclined in opposite directions so that both halves of the grain crop are then fed to the center of the drum 9 where they are unloaded. Rotary combine works as follows. Picker 10 (or the cutting apparatus feeds the beveled grain to the inclined conveyor 11, which directs it to the central part of the casing 12. Then the grain crop enters the drum 8 centrally through the side wall, where it is divided so that the first part of the grain cult It moves along the pressure to one of the ends of the drum, and the second part goes to the other end, subjected to 9 3 threshing while passing to the end, where it moves along channels 18 to the second drum 9 and after further threshing moves towards the center drum 9 (or auger), where it is unloaded at the center of drum 9 (or auger) at right angles to it on the straw walker. Both of the described embodiments of the proposed design allow to thresh various cultures without adjusting the machine and without adjusting the clearance between blades and lower threshing grids (decks). Adaptation to various cereal crops is accomplished by changing the rotating blade drum, the proposed machine works much easier than combine harvesters or threshing stroystva used at present. The proposed device improves the performance of the rotary combine. . Claims of the invention A rotary harvester comprising a wheeled support frame, a pick-up, a feed conveyor, behind which is a casing placed in a casing with side outlets, a transverse drum with a lattice concave, means for connecting the combine with an energy source different from and In order to increase productivity, the transverse drum is cylindrical with blades, and behind it is an additional cylindrical paddle drum with lattice placed in the casing, which has side entrance windows fifth concave, wherein the inner surface of the casings are attached guide ribs for conveying grain mass main drum from its center to the ends, and further - the ends of the central exit port, wherein the side window casings are interconnected by channels.
