Abstract

FIELD: agricultural engineering. SUBSTANCE: windrow-type header has winder with cutterbar, device for carrying cereal heap away from wheels of power unit, and endless conveyor, said device and conveyor being arranged behind cutterbar. Conveyor has drums and belt. Gate with brushes is positioned at the end of conveyor. Gate is connected to raising mechanism. Said device and said endless conveyor have common drive. During operation, mowed stalks are carried away by belt of endless conveyor to gate with brushes, which prevent cereal heap from leaving endless conveyor. Upon termination of accumulation of cereal heap on endless conveyor, when windrow is formed, raising mechanism raises gate with brushes. Part of cereal heap is transferred from endless conveyor onto stubble. EFFECT: increased efficiency and reduced cereal heap loss. 2 dwg

Description

 The invention relates to agricultural machinery and can be used to create roller header harvesters.

 Known roll header containing a cutting apparatus, a conveyor located behind the cutting apparatus of the device for removing the grain mass from the wheels of the energy means and the drive mechanism (RF patent 2138150, A 01 D 57/20, 1999).

 However, in the well-known reaper on the platform from the effects of the swath-forming belt conveyor, partial threshing of the grain mass occurs. In case of untimely unloading of the grain mass into the roll, it is unloaded on the field. The formed roll is obtained with large deviations from straightness.

 The purpose of the invention is to reduce the loss of grain mass during the formation and selection of portioned rolls and deviation from the straightness of the formed roll, soil compaction by reducing the number of passes of the combine on the selection of rolls.

 The problem is solved in such a way that the roll header containing the cutting apparatus, the conveyor, located behind the cutting apparatus of the device for removing the bread mass from the wheels of the energy means and the drive mechanism, is characterized in that it is equipped with a shutter with brushes located on it and a lifting mechanism, while the conveyor contains drums and tape, and a shutter with brushes is located at the end of the conveyor and is connected to the lifting mechanism.

 The proposed design is illustrated by drawings.

 In FIG. 1 shows a roll header, general view; figure 2 is a section aa in figure 1.

 The proposed roll reaper includes a reel 1, a cutting apparatus 2 located underneath it, and devices 3 behind the last to remove the grain mass from the wheels of the energy tool and a continuous conveyor 4 containing drums 5 and belt 6, at the end of which there is a shutter 7 with brushes 8 connected to the lifting mechanism 9. Moreover, the drive of the device 3 for removing the grain mass from the wheels of the energy means and the continuous conveyor 4 is common.

 The device operates as follows.

 The process of forming a bread roll by the proposed reaper consists of preliminary accumulation of bread mass on a belt 6 of a continuous conveyor 4 in the form of a portion and its subsequent unloading on a stubble in a portion roll. The bread mass immediately after mowing by the cutting apparatus 2 is placed by the reel 1 on the device 3 for removing the bread mass from the wheels of the energy tool and on the front of the continuous conveyor 4.

 Devices 3 for removing the mass of bread from the wheels of the energy means continuously shift the mass of bread onto the layer of bread mass located on the continuous conveyor 4. As the mass of bread accumulates on the belt 6 of the continuous conveyor, the stems are diverted from the cutting apparatus 2 to the shutter 7, which prevents blowing of the grain mass, and brushes 8 located on it, preventing the gathering of bread mass and preventing the release of grain on the belt 6 of the continuous conveyor 4. There is an accumulation of bread mass on the tape 6 of the continuous conveyor 4. B the moment of the end of the accumulation of bread mass and the achievement of the roll formation strip, the lifting mechanism 9 lifts the shutter 7 with brushes 8, including the increased speed of the belt 6. By raising the shutter 7 and the increased speed of the belt 6 of the continuous conveyor 4, the portion is placed on the stubble, while the newly unloaded portions are docked to servings of the previous pass.

 After unloading a portion of the cereal mass into the roll, the lifting mechanism 9 lowers the shutter 7 with brushes 8, turning off the increased speed of the belt 6. The process of accumulating a new portion begins.
