Description

A device for soil disinfection by infrared radiation in a protected soil against diseases and pests relates to agriculture. The technical result achieved by the implementation of this device is to increase energy efficiency during disinfection of the soil.

The invention is known from the prior art for disinfecting soil in sheltered soil [1], which consists in the fact that a steam distributor with a perforated hose is placed on the soil surface, over which a layer of zeolite 10 ... 12 cm is poured, everything is tightly covered with a heat-resistant film and steam is supplied with a pressure of 30 ... 50 kPa for 5 ... 3 min, followed by a decrease in vapor pressure. This reduces energy costs and improves the quality of disinfection while improving fertility.

Another well-known invention for soil disinfection [2], including heating the soil with an ultra-high frequency electromagnetic field, characterized in that the soil is heated to a temperature of 64 ... 70 ° C at a rate of 0.04 ... 0.5 ° C / s with temperature control without supplying heat to a flow of at least 180 s at a cooling rate of the soil of not more than 0.05 ° C / s.

A device for thermoelectric disinfection of the soil [3], consisting of an electric heating chamber, inside which there is a blade screw, the drive of which includes an electric motor and gearbox, characterized in that the electric heating chamber is made in the form of two coaxially arranged pipes through which an electric current of the same frequency flows, but in opposite directions, as a result of which, in accordance with the Lenz-Joule law, the pipes are heated and the necessary temperature field is formed inside the electric heating chamber.

All of the above inventions work on various tillage methods. Their main disadvantages are complexity in the design due to their bulkiness, which is reflected in their reliability, and low heating efficiency.

From a review of scientific and technical literature, it is known that infrared (hereinafter referred to as IR) heating is used to quickly warm the soil of a greenhouse for early planting.

The technical task of the proposed utility model is to increase energy efficiency during soil disinfection.

The device is illustrated in FIG. 1, which shows a device for disinfecting soil with IR radiation.

The soil disinfecting device includes a frame 1, on which IR burners 2, wheels 3, a platform 4 for a gas cylinder 5 are mounted, a handle 6 for moving the frame, a gearbox 7, a distribution comb 8, rubber reinforced gas hoses 9, connecting the distribution comb to an IR -burners.

The device operates as follows. Gas from the cylinder is supplied to the gearbox, where, by means of a distribution comb, it diverges through the rubber reinforced gas hoses and enters the IR burners. Burning gas in the burners heats the ceramic elements that emit infrared rays. The burners are bolted to the frame. For the convenience of moving the frame, a handle and four wheels are installed on it. The wheels are attached to the frame with the ability to adjust the height of the frame above the ground with screws, and therefore the intensity of the effect of infrared radiation on the soil surface and the depth of penetration of infrared rays. The power of using infrared burners varies between 10 ... 15 kW and can be regulated by a gearbox. IR burners on the frame are mounted in a row (or several rows) of several pieces, depending on the area of simultaneous heating and the scale of production. The temperature of heating the soil depends on three main factors: the heating time, the height of the frame above the ground and the power of the burners. For ease of operation and mobility of the installation, the gas cylinder is mounted on the platform to the frame.

High energy efficiency of the device is achieved by high efficiency of infrared burners and infrared radiation acts directly on the processing object - the soil.
