RU202119U1 - Device for determining the infestation of plants - Google Patents

Abstract

The utility model relates to the technical means of sampling for the analysis of microparticles contained in the air above plants (and on plants) in order to indicate the spores of phytopathogenic fungi and other microorganisms and can be used in phytosanitary monitoring of agricultural crops for early detection of foci of infection with fungal diseases. The device for determining the clogging of plants contains a housing with an aspirator and a glass holder with a glass slide and a side bar with a handle for installing the glass in the required positions, a slotted nozzle mounted on a hinged lid, and a control unit that provides sound and light signals at a given time, installed at the bottom of the case. In this case, the control unit consists of a microcircuit, an on / off button, a speaker, a timer, and a control lamp. Power is supplied by the battery.

Description

The utility model relates to technical means of sampling for the analysis of microparticles contained in the air above plants (and on plants) in order to indicate the spores of phytopathogenic fungi and other microorganisms. The useful model can be used for phytosanitary monitoring of agricultural crops for early detection of foci of fungal diseases.

Known determinant of infestation of plants (Sokolov Yu.G., Evsyukov N.A., Sadkovsky V.T. Recommendations for the use of infection control and environmental parameters in protecting plants from diseases - M., 1994. - 33 p.), Including an aspirator , a slotted branch pipe for air intake and a glass holder with a stem, located in a common housing. The glass holder can be installed in five different positions relative to the slotted tube by extending the stem from the device body.

Such a design is cumbersome, has a low sampling ability, makes it difficult to clean and disinfect the slotted nozzle, and does not allow promptly adjusting the sampling time.

The closest to the proposed device is a plant congestion detector (RF patent for a useful model No. 100621, publ. 20.12.2010, bull. No. 35), which contains a housing with an aspirator and a glass holder with a microscope slide. The body is equipped with a hinged lid with an attached slotted pipe, and the glass holder is equipped with a side bar with a handle for installing the glass in the required positions.

The disadvantage of the device is the need for constant visual control of the density of deposition of particles on the slide in the intervals between individual samples.

The technical result to be achieved by the present model consists in creating a device for determining the infestation of plants, which makes it possible to quickly control the density of deposition of particles on the slide and to take up to 7-10 samples by sound and light signals at certain intervals set by a timer.

The achievement of the specified technical result is provided by a device for determining the clogging of plants, containing a housing with an aspirator and a glass holder with a glass slide and a side bar with a handle for installing the glass in the required positions, a slotted pipe installed on a hinged lid, and a control unit that provides sound and light signals at a given time, installed at the bottom of the case. In this case, the control unit consists of a microcircuit, an on / off button, a speaker, a timer, and a control lamp. Power is supplied by the battery.

Figure 1 shows a general view of a device for determining the clogging of plants, figure 2 is a side view with a reclining branch pipe, figure 3 is a sectional view of the control unit for sound and light signals.

The device contains a housing 1, in the lower part of which a control unit 2 is installed, consisting of an on / off button 3, a control lamp 4, a timer 5, a speaker 6, a microcircuit 7 and a battery 8, a slotted pipe housing 9, a glass holder 10 with a side bar 11, having a through groove 12, with a handle 13 attached to it for moving the slide 14, hinges 15 connecting the cover 16 with the device body by means of screw clamps 17, a hinge 18 of the slotted pipe body, which allows it to be folded down when the lock latch 19 is extended.

The device works as follows.

In preparation for taking a series of samples, the lid of the device 16 is opened, a slide 14 is placed in the glass holder 10, covered with a retention compound (for example, petroleum jelly), with a lubricated surface to the slotted nozzle 9. The specified time interval is set using timer 5, then by pressing the on / off button 3, the control lamp 4 lights up, which indicates that the device is ready for operation. The spores on the plants are sucked into the slotted nozzle 9 of the device due to air currents and are deposited on the fixing surface of the slide 14. After the timer 5 is signaled, the device is turned off, and with the handle 13 the glass holder 10 with the slide 14 is moved to the next position. After moving the glass holder 10, the device is turned on again and so the operation is repeated up to 10 times. After taking the last sample, the device is turned off, the clamps 17 are unscrewed, the cover 16 is opened and the slide 14 with replica prints is taken out.

After the completion of sampling, the slides are examined using a biological microscope, the deposited biological objects are identified and counted.

The results of the analysis of samples are used to indicate the spores of phytopathogenic fungi or other infectious particles for the purpose of early diagnosis of diseases of agricultural plants.
