Description

one

The invention relates to the field of agricultural machinery, in particular to harvesting machines for harvesting rice legumes, having a large amount of oblique mass. In order to activate the supply of cut-off mode: a mass is applied to the conveyor with a reel with tines, which have palets fixed on the tines.

Such a reel has a greater activity in the feed of mass to the cutting apparatus and further to the conveyor, but in the zone of mass movement along the conveyor, the fingers brake because the trajectory of their movement is perpendicular to the trajectory of the conveyor. The mass is held up by the fingers and starts jerking as the fingers come out of it. This leads to the accumulation of mass on the conveyor, twisting it. The exposure time of the reel to the cut mass increases, resulting in additional threshing.

In order to improve the mass flow from the tines of the fingers when they are in the conveyor zone in the proposed header, the fingers are pivotally mounted with the possibility of deviating them in the direction of the conveyor movement and are spring-loaded.

FIG. 1 shows the proposed header, side view; in fig. 2 - finger reel; in fig. 3 is a view along arrow A showing the position of the finger in the zone of the moving mass and section along BB in FIG. 2

An eccentric reel 2 is mounted on the header 1, having articulated fingers 3, which are fixed on rake 4 by means of axles 5. To prevent fingers from swaying during rotation of the reel and the possibility of bending at the moment of entry into the mass to be picked up, they are equipped with a spring 6, made for example sheet material.

During operation of the reel, the reel 2 feeds the mass to the cutting unit with fingers 3. Since the finger does not have a hinge in the direction of rotation of the reel, it does not lose its carrying capacity. By feeding the mass to the cutting unit, the tine handler continues to move it to the conveyor. The conveyor moves the fed mass to the unloading window. As the mass on the conveyor accumulates, the gap between it and the fingers of the reel decreases. As the gap between the fingers and the mass disappears, the finger begins to experience a lateral impact from the mass moving along the conveyor belt and begins to turn in

hinge.

The finger goes out of engagement with the mass. When you lift your finger along the path of rotation of the reel above the mass level on the conveyor, the spring returns the finger to the vertical

position. In this position, the finger is again

starts feeding mass to the cutting unit and to the conveyor during the next cycle.

Subject invention

A harvester containing a cutting machine, a conveyor and a reel, on the tines of which fingers are fixed, characterized in that, in order to improve the mass gathering from the tines of the fingers while they are in the area of the conveyor spring loaded.
