For tillage, electrified mobile machines are used: electric cutter, electric cultivator, electric ripper.

Electromill FS-0,7A is recommended for plots of 3-5 acres, it is used for tillage in personal plots, vegetable gardens, greenhouses, gardens, greenhouses, for the preparation of soil mixtures. Productivity - 790 m/h, width of capture - 700 mm, depth of processing of the soil - from 60 to 200 mm, working speed - 1,13 km/h. Electric motor power - 3 kW. The mass of the cutter is 160 kg, overall dimensions, mm: length - 1835, width - 770, height (adjustable) - 840-1490.

The running wheels of the cutter with lugs and the working bodies (the right and left rotors on which the knives are installed) are driven by a three-phase electric motor with a rotation speed of 1500 min-1, a voltage of 380 V. The diameter of the rotor of the working bodies is 420 mm, the rotational speed is 240 min- 1. The machine receives electricity through a flexible hose four-wire cable KRPT 3x1,5 + 1x1, 50 m long, at the ends of which electrical connectors are mounted. On the panel of the right control handle there is a manual starter, a package switch for changing the direction of rotation of the cutter rotor and a male part of the electrical connector for connecting the power cable of the KRPT.

The machine is supplied with a device consisting of a frame on which a circuit breaker and a drum with a handle for winding the cable are installed. The circuit breaker is designed to protect the supply cable, starting equipment and electric motor from short circuit currents and overloads.

When operating the cutter, it is necessary to strictly observe the safety rules: do not allow the tension of the flexible supply cable and run over by the cutter itself and vehicles; it is forbidden to work with the cutter without personal protective equipment - dielectric gloves and galoshes.

If the cutter is used with a residual current device, then it is allowed to work without personal protective equipment.

electric cultivator Zh-1500 does not have running wheels and moves due to the rotation of the working bodies.

Electric ripper Soil Sh63 "combines" a shovel, a hoe, a cultivator and a harrow. It consists of an L-shaped frame with two handles, a foot clamp and clamps for attaching an electric drilling machine, a working body with three replaceable knives measuring 140, 220 and 270 mm, a fence and a cable 25 m long (section 2x0,75 mm2) with electrical connector. On the right handle of the machine there is a lever with a pull to turn on and off the electric motor of the drilling machine.

The set of tillage machines includes a protective shutdown device. Rippers and cultivators are equipped with a flexible hose cable 15 or 25 m long.

Rotary cultivator, rotary cultivator and electromill - small-sized electrified tillage machines. To drive the cultivator and ripper, manual drilling electric machines IE-1202 and IE-1206 with single-phase electric motors with a power of 420 and 1150 W are used, and a three-phase asynchronous motor with a power of up to 3 kW is used to drive the electric cutter.

small electric lawn mowers selected based on the intended area of processing.

To combat pests and diseases of fruit and berry and vegetable crops, as well as for watering plants, whitewashing trees, in-soil feeding of trees, supplying water from artificial and natural reservoirs, electrified mobile (OEP-60, EOS-3, EOS-5) and portable (SOM, OE-202, ECO, OE-201) "Cascade", "Universal" sprayers.

Mobile sprayers consist of a trolley with two rubber-coated wheels, on which a working fluid tank with a removable lid is located. Inside the tank there is an electric pump "Malysh", a tee for connecting to a pressure hose 10 m long, a switch, a cable 40 m long with an electric plug connector.

Some models of electric sprayers are equipped with a body with a carrying capacity of up to 75 kg, which is mounted on the chassis of a hand truck that can be used to transport goods.

The COM portable sprayer includes a single-phase asynchronous electric motor, a drive mechanism, a diaphragm pump and an atomizer. In addition to the previously listed operations, the sprayer can be used for disinfection, disinsection (destruction of harmful insects), watering horticultural crops, car washing, painting with water-lime and water-chalk solutions with a density of not more than 1300 kg / m (1,3 g /cm) and other household purposes.

The electric sprayer is connected to a single-phase network with a voltage of 220 V only through an RCD residual current device, using a KRPT 2x1,0 cable 16 m long.

Manual low-volume sprayer OM-301 "Fog" has a capacity of not more than 0,1 l / min. working fluid - 2-3 times less than manual sprayers, with greater deposition efficiency. Tank capacity - no more than 1,5 liters. Working width of capture - not less than 1 m. Round elements of the A373 or A343 type are used for power supply. Supply voltage - 12 V, power consumption - 5 W. The weight of the sprayer without batteries is no more than 1,2 kg.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>
