Description

The device for disinfecting seeds belongs to agriculture and is designed to disinfect the surface and stimulate the germination of seeds. The device can be used for disinfection of bulk materials, food, combined feed.

A known method of presowing treatment of wheat seeds [RU 2318305 C1, A01C 1/00 (2006.01), 10.03.2008]. To implement the method, a device is proposed, consisting of a seed bin, an irradiation chamber, emitters, nozzles, a perforated conveyor belt.

The disadvantage of this method of pre-sowing treatment of wheat seeds is the inability to change the duration of seed treatment in the irradiation chamber.

A device for ultraviolet irradiation of bulk materials is known [RU 2537500 C2, A23V 9/06 (2006.01), 10.01.2015]. The design of the device includes: a body, a drum, ultraviolet lamps, a dosing hopper.

The disadvantages of the device include a decrease in the effectiveness of ultraviolet irradiation due to the accumulation of dust during rotation of the drum.

A known installation for pre-sowing treatment of seeds of various crops [RU 82510 U1, A01C 1/00 (2006.01), A61L 9/18 (2006.01), A61L 2/10 (2006.01), A61L 9/20 (2006.01), 10.05.2009] . The installation contains: a drum, an ultraviolet lamp, a drive, a reflector, a frame.

The disadvantages of the device include the lack of protection of ultraviolet lamps from mechanical damage. Rotating the material drum can damage the UV lamps.

The closest solution in terms of technological essence and the achieved effect is a method for disinfecting bulk products and a device for its implementation [RU 2279806 C2, A23B 9/06 (2006.01), A23L 3/54 (2006.01), 20.07.2006]. The device for disinfection of bulk products contains a hopper-dispenser, a vibrating conveyor, a source of ultraviolet radiation.

The disadvantages of the device include the lack of means to control the dose of radiation. Reduced irradiation efficiency due to accumulation of dust over the vibratory conveyor during operation.

The objective of the invention is to provide a controlled process of ultraviolet irradiation of seeds to disinfect the treated crop.

The problem is solved by the fact that the speed of movement of seeds on the tray is controlled by a frequency converter.

The essence of the invention lies in the fact that to implement this task, the proposed device for disinfecting seeds is made of a hopper, a tray, a vibrator, a frequency converter, shock absorbers, ultraviolet lamps, parabolic reflectors, a fan, a casing, an ultraviolet radiation intensity sensor, a frame.

At the same time, a device for disinfecting seeds is necessary to stimulate sprout processes in seeds and disinfect the surface of seeds from mold and fungi. For the possibility of loading and dosing seeds, a dosing hopper is provided. A tray is provided for the possibility of moving seeds under ultraviolet lamps. A vibrator is provided to carry out vibration oscillations of the tray. To control the operating modes of the vibrator, a frequency converter is provided. The tray is mounted on shock absorbers. Above the tray are ultraviolet lamps with parabolic reflectors. A fan is located at the end of the parabolic reflectors. Parabolic reflectors with UV lamps are located in the casing. An ultraviolet radiation intensity sensor is fixed on the tray in the processing zone. The device is made on a frame.

The device for disinfecting seeds will be clear from the following description and the accompanying drawings.

Figure 1 shows a General view of the device for disinfection of seeds, figure 2 shows a cross section of the device for disinfection of seeds.

Device for disinfection of seeds consists of a hopper 1 (figure 1), tray 2 (figure 1, 2), vibrator 3 (figure 1). The vibrator 3 is configured to be controlled by a frequency converter 4. Tray 2 (figure 1, 2) is configured to receive vibration vibrations from the vibrator 3 (figure 1). Tray 2 (figure 1, 2) is installed on shock absorbers 5 (figure 1). Ultraviolet lamps 6 (figure 1, 2) are located at the focus of parabolic reflectors 7. Parabolic reflectors 7 are configured to form a stream of directional radiation from ultraviolet lamps 6 into the treatment area. Radiation from ultraviolet lamps 6 is applied to the seeds and parabolic reflectors 7. To prevent dust accumulation, a fan 8 is provided (figure 1). The fan 8 is mounted from the end of the parabolic reflectors 7 (figure 1, 2). To exclude radiation from ultraviolet lamps 6 on personnel, a casing 9 is provided. The casing 9 is made of a material that does not transmit ultraviolet radiation. In the seed treatment area, there is an ultraviolet radiation intensity sensor 10. The frame 11 (figure 1) is made with the possibility of attaching equipment.

Device for disinfection of seeds works as follows. In the hopper 1 (figure 1) serves the seeds. From the hopper 1, the seeds are dosed onto the tray 2 (figure 1, 2). Using a vibrator 3 (figure 1) tray 2 (figure 1, 2) vibration is reported and the seeds are moved to ultraviolet lamps 6. The required speed of movement of the seeds on the tray 2 (figure 1, 2) is set by the frequency converter 4 (figure 1 ). Parabolic reflectors 7 direct the radiation flux from ultraviolet lamps 6 to the seeds. Fan 8 (figure 1) blow dust from the inner region of the parabolic reflectors 7 (figure 1, 2). On tray 2, seeds are irradiated with ultraviolet lamps 6. As a result, disinfection and stimulation of seed germination are carried out. The radiation intensity is controlled by an ultraviolet radiation intensity sensor 10. After processing, the seeds are ready for subsequent planting or germination.

The proposed device for seed disinfection provides control of the speed of movement of seeds on the tray through the use of a frequency converter.
