The invention relates to agriculture, in particular, to devices for measuring grain loss when setting up a combine harvester for optimum operation, as well as for various types of combine harvesters and determining the throughput of threshers,

A device for determining grain losses is known, which contains a collection of grain made in the form of a shield attached under the bottom of the header by means of electromagnets l,

The disadvantage of this device is that in the process of operation one shield is dropped - the tray and the actual grain losses are determined only in one dead, whereas to eliminate the effect of uneven distribution of yield, humidity to other random factors and, as a result, reliable results it is necessary to determine losses repeatedly-continuously

It is also known a device for determining grain grain losses by a combine harvester, which contains a cassette with grain collections assembled therein, and a piece dropping mechanism of collections on the ground.

In this device collections are made in the form of canvases and are installed in a cassette on protruding rods with the help of chain hangers. For ejecting each collector separately, there is an electromechanical ejector consisting of four spring-loaded rods rigidly connected to protruding rods. -To ensure simultaneous retraction of protruding rods and release of the collector, the spring-loaded rods are interconnected by a system of levers and flexible traps. The pull-in in the retracted position is fixed by a latch controlled by electromagnets. A disadvantage of the known construction is that for ejecting each collection there is a separate electromechanical ejector. which complicates the device and increases its overall height, while the height of the device is limited by the installation location of its sang with a combine thresher.

In addition, to install the collection of them in the cassette, it must be removed from the combine to be installed on the suspension of a separate collection, which is time consuming and inconvenient.

The reliability of the determination of grain loss during sampling using a known device is reduced, since in this case collections made by me canvases, with an emission, they can lose their own

d; ate.-jecTBo selected grain samples, and also leads to the culling of individual samples.

The aim of the invention is to simplify the design and improve the exact point of determining the loss of zerg ..

The goal is achieved by the fact that in the device for determining grain losses by a combine harvester containing a cassette with the grain assemblies installed in it and a piece-by-piece dropping mechanism of the collections to the ground, the latter is made in the form of several cutters, each of which contains two segment disks fixed on the vertical axis , equipped with a rotary drive for their alternate insertion into the cassette, - and each collection of grain is provided with a rigid frame, with a groove on the outside: cd1 segment disc E :.
