Description

one

The invention relates to the agricultural machinery industry, and i specifically to devices for determining the separability of the soil on mobile root-harvesting machines.

The aim of the invention is to increase the reliability of information on soil properties.

Fig. 1 is a schematic diagram of a device for determining the separability of soil on a root-harvesting machine; figure 2 is a functional diagram of the device; in fig. 3 is an example of a specific implementation of a device based on known Hjiix blocks of analog computers.

A device for determining the separability of the soil at the root-harvesting machines contains sensors I and 2 layer thicknesses, installed respectively at the entrance and the gathering of the main separator 3 and connected to the input of the analyzer 4 sifting soil, mode sensors respectively: sensor 5 of the speed V of the elevator , the blade shaking frequency sensor 6, the shaking amplitude sensor A 7, the analyzer 8 operating modes, the separability analyzer 9 and the visual indicator 10 with the control system 11, while the analyzer input 8 re ima work connected with the sensors 5,6 and 7 modes of operation, and outputs analyzers 8 and 4 modes and are connected in sieving .x to the input separability analyzer 9 whose output is connected to a visual indicator 10 and (or) to the remote control system II.

A device for determining the separability of the soil on the harvesting machines works as follows.

The signal of sensors 1 and 2 is fed to the input of the analyzer sifting 4, and the signals of the sensors 5,6 and 7 - to the input of the analyzer 8 mode.

The output signals from analyzers 4 and 8 are fed to the input of analyzer 9 separability, the output of which in turn goes to a pre-calibrated visual observation indicator 10 and (or) remotely to the P control system.

The device is made on the basis of known blocks of analog computers. The separation factor in the analyzer 4 sifting is formed from the signals from sensors 1 and 2 by dividing E 1, / c. The value of the generalized mode characteristic is calculated by decomposing in a series. empirical dependence of R (V,

individual factors and their interactions in the generalized characteristic R with such scaling that their sum is equal to one. In this way,

About i R 1.

I This algorithm is implemented in the 8. mode analyzer. Depending on the desired approximation, the calculation algorithm is, therefore, the Analyzer circuit may be different.

 It is known that the separation factor is exponentially dependent on the mode and property of materials exp (- j R).

From the last dependence, separability is determined by the expression

what is calculated in separability analyzer 9 based on that obtained, and R, after which the signal goes to visual indicator 10 and (or) is remotely transmitted to a high rank control system.

This device provides reliable information about the properties of the soil - the separability necessary for optimal control of cleaning at the household level. At the same time, information is obtained during the work of the harvesting machine, which does not require additional equipment and personnel and helps the combine operator to intervene promptly

in the operation of the machine. In addition, the device is useful for scientific research, contributes to the certification of fields, the accumulation of information

to predict possible changes, it is optimal to plan and manage scientific research institutes depending on the meteorological process of harvesting under domestic conditions. All this allows a level.
