The invention relates to agriculture, mainly to agriculture, and is used for decontamination of soil from harmful microfloras root-knot nematodes and complexes mushrooms (fusari, rizoctonia etc), for example, in greenhouses.

High-frequency heating of dielectric materials (in this case soil) is when they are placed between the plates of the capacitor connected to the high voltage when the high frequency current.

Known stationary device for sterilization of the soil (A.S. USSR №1416068, IPC And 01 In 47/00, 1988), which includes a source of electromagnetic waves, pipeline, located in the working chamber, a device for loading and unloading material, hopper feeder, gauges, levels, and relay elements.

The disadvantage of this device is the low quality of disinfection due to uneven heating of the soil and its immobility, which increases the overall cost of tillage.

Also known mobile thermal installation, includes a source of electromagnetic waves, conveyor, and an unloading device, moreover, it is provided with a device for moisture, temperature sensors and humidity control device, the control devices of the interelectrode distance and the regulation of water supply, the first and second delay blocks, the parallel download the full conveyor device hydrate, in which each row of blades installed at different heights along the entire length of the infeed conveyor. Moreover, each knife has a spray of water, the humidity sensor on the discharge part of the infeed conveyor, and a temperature sensor is installed after running capacitor along the conveyor, and a temperature sensor associated with the first input control device, which is also connected by its outputs to the control unit interelectrode distance and a device for regulating the supply of water in the humidification device while the control device is connected two-way communication link with the first delay unit, to which is also connected the output of the humidity sensor, in addition the corresponding output control device via the second delay unit associated with the respective input of the first delay unit and a humidity sensor (patent Of the Russian Federation No. 2064228, IPC And 01 In 47/00, 1992, prototype)

The disadvantage of this device is the low quality of soil disinfection due to uneven heating of the soil.

Object of the invention is a device for improving the quality of decontamination of the soil in the boxes (in the greenhouse), increasing productivity through mobility and automatic process control.

The technical result, unlike the prototype, is achieved by TRG is, what setting for disinfecting the greenhouse soil, comprising a source of electromagnetic waves, the device of the transport device for loading and unloading device, moisture, humidity sensors and temperature, the system control unit, the control device interelectrode distance and regulation of water supply, is also provided with a device for moistening presented in the form of the agitator, made in the form of two displaced blades, in which sensors are mounted humidity and temperature in the upper part of the agitator equipped with telescopic piston in the center of which is a through channel for water, which, in the area of the blades of the agitator branched in the side channels, ending nozzles high pressure, and the working chamber is provided with two vertically spaced parallel high - and low-potential plates, though the plant is equipped with a microprocessor.

Figure 1 shows the General view of the device for disinfecting the greenhouse soil, front view; figure 2 is a top view of figure 1, section a-a; figure 3 is a side view of figure 1; figure 4 presents the working chamber; figure 5 presents the agitator.

Device for disinfecting the greenhouse soil consists of a frame 1 (Fig 1), which is the case of the working chamber 2, which in turn are attached to the elements of the device of moisture. The humidification device is represented by a capacity of 3 for water with an integrated high-pressure pump (not shown), the motor 4 and the agitator 5, the hydraulic pump 6 and the drive motor 7. The pump 6 operates telescopic piston reciprocating motion 8 in the cylinder 9.

The entire length of the installation on the frame 1 is mounted a roller conveyor 10 (2, 3), at the beginning of which the frame 1 is set to a device receiving and aligning boxes 11. At the end of the conveyor 10 on the frame 1 is mounted a tray 12 unloading boxes 17 (figure 2).

The conveyor 10 (Fig 1) is driven by a gear 13 from electrodepot 14 by means of a belt 15.

The automatic control unit is a microprocessor 16 mounted on the frame 1. To measure the initial data of the soil in the box 17 in the base offset of the blades of the agitator 5 is equipped with a humidity sensor 18 and the temperature sensor 19 (figure 5).

For mobility installation on the frame 1 (Fig 1) set the drive 20 and the drive rotation 21 of the wheels 22, actuated by the motors 23 and 24.

The working chamber 2 (figure 4) provided with two vertically mounted parallel plates: 25 high-potential and low-potential 26 connected to the RF generator 27. The distance between the plates varies p is the water 28. The working chamber 2 is protected by a screen 29.

The agitator 5 (figure 5) is designed as two offset of the blades 30, which placed the humidity sensor 18 and the temperature sensor 19. In the upper part of the agitator is telescopic piston 8 reciprocating motion that is installed in the cylinder 9 (Fig 1). In the center of the telescopic piston 8 is through channel 31 for supplying water, which, in the area of the blades of the agitator breaks into side channels 32, ending nozzles high pressure 33.

The device operates as follows.

Box 17 with infected greenhouse soil by conveyor 10, passing through the acceptance and alignment of the boxes 11, enters the area of the agitator 5. Simultaneously with the lowering of the stirring shaft 5 rotates, when the cutting into the soil is mixing it. Before water, humidity sensors 18 and temperature 19 are determined by the initial soil parameters, the microprocessor 16 determines the wetting time and the switching time of the working chamber. Next, the contaminated soil moisture through the channels 31, 32 and nozzle high pressure 33 to the desired parameter.

After moistening box 27 by means of the conveyor 10 enters into the working chamber 2 - the range of electromagnetic field of high frequency which is heated infected the th soil and its disinfection within already defined by the microprocessor 16 time.

After processing, the drawer 17 leaves the working chamber 2, sliding the tray 12.

The agitator 5 performs two functions, such as hydration and mixing. Depending on the task in the water, you can add minerals and microadditives.

Since the distance between the plates 25 and 26 of the working chamber 2 can be changed, the proposed installation is universal. Therefore, in this setting it is possible to cultivate the soil of different composition, as well as to pre-sowing seed treatment.

When using this installation is improving the quality of decontamination of the soil due to more uniform distribution of RF energy in a pre-moistened soil, and increasing productivity through mobility and automatic process control.

Manufacturer installation is not difficult for medium-sized enterprises of the corresponding type.
