Abstract

GRAIN COMBINE on auth. No. 869632, characterized in that, in order to reduce grain losses by adjusting the degree of agitating of the roll, each slope is rotatable relative to the axis of the corresponding drum of the USSR and is provided with a position lock.

Description

The invention relates to agricultural 13 grains. For blowing cleaning sieves.

economic engineering ^ can be used in the construction of combine harvesters.

By main auto W 869632 of 5 reports a combine harvester containing an inclined chamber, a threshing device with a straw walker mounted on it, made in the form of an agitator, containing a number of palm-shaped drums with ramps and a number of jack balers installed above them, as well as a hopper and a device for purification of grain from small impurities, and the combine is equipped with an additional $ 1 sieve installed under the agitator £ 1].

The disadvantage of a ’/ a combine harvester is a significant loss of grain as a result of the absence of the ability to regulate the degree of tedding of the roll.

The purpose of the invention is the reduction of grain losses by controlling the degree of tedding of the roll. 25

This goal is achieved by the fact that in a combine harvester, each slope is made rotatable relative to the axis of the corresponding palm drum and is equipped with a position lock.

In FIG. 1 shows a diagram of a combine harvester / in FIG. 2 finger drums with pivoting ramps.

The combine harvester contains a header 1 with a reel 2 and a picker 3, a finger auger 4, an inclined chamber with a floating conveyor 5 and a bottom 6. Behind the conveyor 5 is a receiving beater 7, behind which a tedder is mounted, containing a number of finger drums' 8 with slopes 9. Above the last are the bumpers 10. Under the agitator there is a sieve 11. The harvester also contains a cleaning 12 and the hopper and sieve 11 is equipped with fans 14.

Each ramp 9 is made rotatable relative to the axis of the corresponding drum 8 and is equipped with a position lock, which may contain a handle for turning the ramp and a sector with graduation (not shown). The rotary execution of the ramps 9 should provide a change in the angle of their inclination to the plane passing through the axis of the finger drums 8 within 0-45.

Combine harvester operates as follows.

The cereal mass laid in the roll is selected by picker 3 and, via the screw 4 of the conveyor, 5 is fed to the agitator with a beater 7. The grain released during the tedding of the mass enters the sieve 11, and then to the cleaning 12, from where it is sent to the grain hopper 13 in a purified form.

In the case of admission to the agitator significantly moistened mass, the angle of inclination of the ramps 9 is increased up to 45. If the mass is supplied with normal humidity, the slope angle of the slopes is reduced to O® '. In this case, in the process of tedding the mass, there is no violation of the roll structure due to a decrease in the tedding intensity. The increase in the angle of inclination of the slopes 9 is dictated by the need to increase the tedding intensity when processing a wet mass. In the process of tedding, the mass is partially dried, and then again placed in the roll on the stubble.

The ability to adjust the angle of inclination of the slopes in a vertical plane allows, depending on the state of the bread mass, to change the intensity of its tedding without disturbing the roll structure as much as possible, which reduces grain losses.
