Description

The pick-up relates to agricultural machinery, in particular to pick-ups of grain and hay harvesting machines.

A pick-up is known, which contains drums with spring pick-up tines mounted on the frame at an angle to each other and a Cl 3- elevator conveyor placed behind them.

The disadvantage of the known device is an incomplete selection of plants.

The purpose of the invention is to provide a more complete selection of plants.

This goal is achieved by the fact that the drums are equipped with conveyors installed behind them, and the elevator conveyor has picking-up working parts, while the drums with conveyors are hinged to the frame and have hydraulic cylinders for changing their angle of attack.

And: picking up the working bodies are made in the form of a series of spring tines.

The drawing schematically shows a pick-up.

The pick-up consists of drums 1 arranged at an angle to each other with spring pick-up tines. Conveyors 2 are located along the reels 1 along them. In the alignment of the reels 1, there is an elevator conveyor 3 connected under the conveyors 2. A pushing bracket 4 and a hydraulic cylinder 5 having spherical hinges are attached to the frame of each of the reels with conveyors g. Elevator pick 3 is provided with rows of elastic tines 6, spaced 3-4 cm apart from each other.

Picker works as follows.

Moving along the roll, the side drums 1 with their rakes reliably lift the stems open either parallel to the axis of the roll or at a small angle to it. At the same time, the grab-in paths of trajectory intersect with the axes of the lying stems, which determines the reliability of the lifting even of the separately lying stems or ears. The raised roller is carried by tines and fed to conveyors 2, dumping the grain mass to the central area — an elec- tronic conveyor 3. The latter delivers the mass to the transporting organs of the combine thresher or to the header and further to the thresher.

Depending on the angle between the stems and the roll axis, the alignment angle of the side drums 1 is changed by means of hydraulic cylinders 5. Side drums 1 with conveyors 5 2 well copy the field micro-relief, due to the design of pushing brackets 4 (drive not shown; and hydraulic cylinders 5.

If the stems form an angle close to 90 ° with the roll axis, then the selection should be carried out with only one side picker section - drum 1.

If the individual spikelets and stems remain unattached, then turning the rakes of the drums 1 at an angle to the roll axis, they are reliably selected by the densely mounted rakes 6 of the elevator conveyor 3.

The proposed device provides a more complete selection of plants 0 with a floor.

Claims (2)

1. A picker containing drums with spring picking rakes mounted on the frame at an angle to each other and an elevator conveyor placed behind them, characterized in that, in order to more fully select plants, the drums are equipped with conveyors installed behind them, and the elevator conveyor has selecting working bodies ^ while the drums with conveyors are pivotally connected to the frame and have hydraulic cylinders to change their angle of attack. 2. Sorter by π. 1, which is characterized in that the selecting working bodies are made in the form of rows of spring rakes.
