Description

The invention relates to agricultural engineering and can be used, for example, in tillage.

A tillage cutter is known, containing electric motors and gearboxes for drives of active working bodies and running wheels, a tracking device in the form of a cutting knife that allows you to track the change in cutting resistance of the soil and is associated with control units for the frequency of rotation of the shafts of the electric motors of the drive of the running wheels and working bodies that provide regulation of the operating mode of the cutter ( RU200945, IPC А01В 33/082, published 11/20/2020).

The disadvantages of the known device is the effect of additional resistance to cutting the soil of the cutting knife on the measurement of soil hardness and the decrease in the quality of tillage, which leads to an increase in the energy intensity of tillage, increased operator fatigue and reduces work productivity.

The technical result consists in improving the quality of tillage by reducing the cutting resistance of the soil by a disk soil hardness scanner.

The essence of the invention lies in the fact that the adaptive tillage cutter includes electric motors and gearboxes for drives of active working bodies and running wheels, control units for the rotational speed of the shaft of electric motors for driving the running wheels and active working bodies. It additionally contains a disk scanner that sends a signal to the speed control units of the drive motors of the travel wheels and active working bodies, with the ability to track changes in soil hardness by means of a strain gauge kinematically associated with it.

The drawing shows an adaptive tillage cutter.

The adaptive tillage cutter includes a gearbox 1 for driving active working bodies 2 with a rigidly mounted electric motor 3 for driving active working bodies 2 and a gearbox 4 for driving the running wheels 5 with a rigidly mounted electric motor 6 for driving the running wheels 5, respectively. On the control units 7 and 8, respectively, the speed of the shaft of the electric motor 6 drive of the road wheels 5 and the speed of the shaft of the electric motor 3 of the drive of active working bodies 2, a signal is supplied from the disk scanner 9, which freely rotates on its axis 10 and monitors the change in soil hardness by means of a kinematically connected with it, a strain gauge sensor 11 and a signal that sends a signal to control units 7 and 8, which in turn adapt the operating modes of the cutter to the agrotechnical requirements of tillage.

Adaptive tillage cutter works as follows. The device is brought to the edge of the treated area. The electric motors 3 and 6 are supplied with power through blocks 7 and 8 for controlling the rotational speeds of their shafts. First, the electric motor 3 of the drive of active working bodies 2 is turned on, then the electric motor 6 of the drive of the road wheels 5. Simultaneously with the start of the movement of the tillage cutter, the soil hardness is measured by the scanner 9. As the device moves, the scanner 9 monitors the change in soil resistance. When moving on compacted areas, the disk scanner 9 monitors the change in the cutting resistance of the soil by means of a strain gauge 11 kinematically associated with it and sends a signal to the control units 7 and 8, which change the rotational speeds of the shafts of the electric motors 3 and 6. That is, when moving along a compacted soil area the translational speed of the machine decreases and the frequency of rotation of the active working bodies decreases, in the area with less hardness, on the contrary, the tillage cutter adapts the operating mode to external conditions, thereby ensuring uniform engine loading, increasing the reliability of the drive elements, the quality of tillage and work productivity

Compared with the known solution, the proposed design of an adaptive tillage cutter will improve the quality of tillage and work productivity through the use of a disk soil hardness scanner and ensure the agrotechnical requirements for tillage, increase its efficiency, reduce the energy intensity of tillage, and reduce operator fatigue.
