Abstract

FIELD: agriculture.

SUBSTANCE: rotary cultivator contains a gearhead of the running wheels and a gearhead of the tillage tools acting as a frame. Running wheels and tillage tools are fixed correspondingly on the axles of gearheads. Electric motor of the driving unit of the tillage tools, lever with control unit and gearhead of the running wheels are rigidly fixed on the gearhead of the tillage tools. Electric motor with a rotation frequency control module is fixed on the gearhead of the running wheels. Control module is kinematically connected with a spring - driven hanging knife through a lever tracing density variation of the soil.

EFFECT: ensures balanced motor load, will increase operational safety of the elements of the driving gear, quality of tilling and its productive capacity.

Description

The invention relates to agricultural machinery, in particular to small-sized self-propelled manual tillage machines driven by an electric motor, and can be used for loosening soil in greenhouses and greenhouses.

Known electrophoresis, including a two-wheeled chassis, a gearbox of the chassis drive with half shafts installed in the housing, a drive mechanism for working bodies enclosed in the housing, an electric motor with a control panel (SU 671756, IPC ³ А01В 33/02, published on 05/30/1981).

A disadvantage of the known electrophoresis is the lack of the ability to control operating modes (knife feed) depending on external soil conditions, which leads to a decrease in the quality of soil cultivation, to overloading of the operating elements of the drive, electric motor, as well as to increased operator fatigue, which negatively affects the productivity of the work.

The technical result consists in achieving uniform engine load, increasing the reliability of the drive elements, the quality of the soil treatment and productivity.

The essence of the invention lies in the fact that in a tillage mill, which includes an electric drive for driving the working bodies, as well as gear drives for driving the driving wheels and the drive of working bodies, on the shafts of which the running wheels and working bodies are mounted, respectively, on the gear drive of the working bodies acting as a frame, it is rigidly the electric motor of the drive of the working bodies, the lever with the control panel, the gear of the drive of the driving wheels with an electric motor fixed to it with a control unit for its rotation speed are fixed la kinematically connected via a lever with a spring-loaded knife Cherenkov with tracking changes in soil density.

In Fig.1 shows a tillage mill, in Fig.2 - mounting a spring-loaded knife.

The tillage mill (figure 1) contains a gearbox 1 of the drive of the working bodies 2, acting as a frame on which the electric motor 3 of the drive of the working bodies 2, a lever 4 with a control panel 5, a gearbox 6 of the drive of the driving wheels 7, on which the electric motor 8 is fixed A control unit 9 for controlling the speed of the shaft of the electric motor 8 of the drive of the driving wheels 7 is also fixed on the gearbox 1 of the drive of the working bodies 7. Through the lever 10, the control unit 9 for controlling the speed of the shaft of the electric motor 8 is connected to a handle 11 with a spring 12 that allows you to hold the knife in an upright position.

Tillage mill works as follows. The device is brought to the edge of the treated area. The power cable should be located on the side of the side edge of the treated area. The power is supplied in parallel to both electric motors 3 and 8, but in this case, the power of the electric motor 8 is carried out through the speed control unit 9 of its shaft. First, the electric drive 3 of the drive of the working bodies 2 is turned on, then the electric motor 8 of the drive of the driving wheels 7. Simultaneously with the beginning of the movement of the tillage electrophoresis, the cuttings knife 11 and the tillages work tools 2 are deepened. As the device moves, the cuttings knife 11 monitors the change in soil density. When moving in the sealed areas, the cutter blade 11 deviates from its original position and, by means of the lever 10, a signal is supplied to the control unit 9, which changes the speed of the shaft of the electric motor 8 of the drive of the driving wheels 7. That is, when driving on compacted soil, the soil cultivating electrophoresis reduces its speed, thereby reducing the supply to the working bodies 2, which allows high-quality loosening and crumbling of the soil. In addition, reducing the feed to the working bodies 2 can reduce the dynamic load on the drive elements 1, 6 and the electric motor, reduce operator fatigue and increase productivity.

Claims (1)
