Abstract

The invention relates to an agricultural technique, in particular to combine harvesters with an axial feed of grain mass. The purpose of the invention is to reduce the loss of grain in the straw by stabilizing the air flow in the chamber. The threshing and separating device includes a rotor 2 with scourges 3, located in the casing 1 with the discharge chamber 4. In the lower part of the discharge chamber, a conveyor 9 is installed above which the shield 10 with springs is located. The grain mass at the interaction of the casing 1 and the rotor 2 is threshed and separated. In the back of the casing 1, the pests 3 of the rotor 2 emit threshed straw into the chamber 4. The conveyor 9 draws the straw in a narrow stream. A section flap, hinged at the rear wall, is pressed against the moving straw with springs to prevent the air flow from the threshing and separating device through the discharge window and ensures that grain is separated from the straw. 1 hp f-ly, 4 ill.

The invention relates to agricultural machinery, in particular to a combine harvester with axial mass movement.

The purpose of the invention is to reduce grain losses by stabilizing the air flow in the chamber.

FIG. 1 shows a combine harvester with an axial-rotary threshing and separating device in FIG. 2 - unloaded camera, rear view; in fig. 3 is the same side view in FIG. 4 - sectional shield.

The axial-rotary threshing and separating device contains an elongated cylindrical casing 1 and a rotor 2 with scourges 3 installed in the rear part of the casing 1 an unloading chamber 4 for discharging the fracture radially bounded by the cochlear surface 5, the front 6 and the rear 7 walls installed directly in unloading window 8 unloading chamber 4 conveyor 9, pivotally mounted on the rear wall 7 of the section shield 10 and the spring 11.

The flap consists of separate sections 12, which are made of elastic material 13, mounted on the housing 14.

Monstilno-separating device operates as follows.

The grain mass at the interaction of the casing 1 and the rotor 2 is threshed and separated. The whips 3 of the rotor 2 in the back of the casing 1 are threshed thrown into the chamber 4. The exit of the straw is a thin dense layer

moves along the cochlear surface 5. The front 6 and rear 7 walls prevent the scattering of straw outside the chamber 4. The conveyor 9 in a narrow dense layer draws the straw away from the threshing-separating device. Sectional flap 10, pivotally mounted on the rear wall 7,

The springs are pressed against the moving salt of the fflt mass, which prevents the air flow from the threshing and separating device through the discharge port 8 and ensures constant conditions for the separation of grain from the straw. The threshed and separated grain is fed for cleaning and then into the grain tank.
