FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for controlling the operation of agricultural harvesting machines, mainly harvesting machines.

A device is known for determining the production of harvesting machinery. Agricultural machinery, including a material presence sensor, connected to an adder and meter, a switch, and a path sensor 1.

The disadvantages of the known device are the complexity of its electrical circuit, the presence of electronic devices, dependence on extraneous current sources. Under field conditions, as confirmed by tests, the reliability of determining the output of a known device is low, and the cost of its manufacture is high.

The purpose of the invention is to simplify the device and increase the reliability of the process of determining the actual production of agricultural machines.

This is achieved by the fact that in the device for determining the production of agricultural machines, including a rotation sensor of the working bodies, a counter, material presence sensors uniformly distributed over the working width and the corresponding number of path sensors, the rotation sensor of the working bodies is made

the form of a magnetoelectric generator, with which path sensors, material availability sensors and a counter are connected in series.

The drawing shows schematically a block diagram of a device for determining the production of a flax harvester. The device includes a rotation sensor 1 of the working body of the machine, sensors 2 of the pass path, sensors 3 for the presence of material and counter 4.

The sensors of the path and the sensors of material, for example contact, open, are controlled by magnets. The position of the contacts of sensors 3 in the presence of material is closed, in the absence of material it is open.

When driving a car in an array of plants with rotating tools

rotation sensor 1 — the generator supplies current to the sensors 2 paths. When a magnet connected to the chassis of the machine passes over the sensor 2, the latter produces a current pulse, which, in the presence of material, passes through the closed contacts of the sensor 3, is detected by the counter 4 and digitally shows the operator the machine output. The current pulse corresponds to the unit area defined by the period

the accuracy of the trip sensor operation

width, controlled by sensor 3. The emulsions of the next row of sensors are added together by a counter.

The device provides information only when there is a simultaneous rotation of the working bodies, the machine, and the presence of material, such as plant stems, in the working bodies. It does not react when moving, idle work on site or on the go.

Equipping the agricultural machinery with a device for determining the output will improve the accounting of the treated area, promptly inform the operator about the work rate at any time of the shift, as well as improve the self-control of the work performer. Saving from the use of the device arises from the expected increase in the rate of performance of work and from reducing the cost of the device compared to the prototype.
