Description

The utility model relates to agriculture and is intended for surface disinfection and stimulation of germination processes in seeds. The seed treatment unit can be used for disinfection of bulk materials, food products, and combined feeds.

A device for pre-sowing treatment and loading of seeds [RU 218216 U1, A01C 1/00 (2006.01), 16.05.2023] and a device for ultraviolet treatment during loading of seeds [RU 218681 U1, A01C 1/00 (2006.01), 06.06.2023] are known. The design and operating principle of both devices are similar. The devices include a hopper, a gear motor, an auger, a casing, an unloading zone, ultraviolet lamps, parabolic reflectors, windows, tension latches, a frame, wheels, a support with a wheel, a cable with fasteners, and a control panel.

When the devices are operating, a large mass of seeds passes through the processing zone, and the flow of ultraviolet radiation through the windows reaches only the upper layers of seeds, while the seeds in the depths remain untreated, which is a significant drawback.

A device for ultraviolet treatment of grain before germination is known [RU 2728184 C1, A01C 1/00 (2006.01), 28.07.2020]. The device contains a hopper, a control panel, an electric drive with a gearbox, an auger, a damper, a casing, a casing cover, an ultraviolet lamp, a reflective coating, an unloading compartment and a frame.

The disadvantages of the device include low uniformity of ultraviolet treatment of grain when the mass is moved by a screw.

A device for ultraviolet treatment of seeds before germination is known [RU 2751843 C1, A01C 1/00 (2006.01), 19.07.2021]. The device consists of a dosing hopper, an electric drive, an auger, ribs, a casing, an ultraviolet lamp, a parabolic reflector, an unloading compartment, a chain drive and a frame.

The disadvantages of the device include operation in one mode with a fixed auger rotation speed, while there is no possibility to control the speed of movement of the irradiated seed mass during processing.

The objective of the utility model is to increase the uniformity of ultraviolet treatment of seeds before sowing.

The technical result is aimed at disinfecting seeds, namely reducing the overall microbial contamination, disinfecting the surface of seeds from mold, fungi and stimulating germination processes. The technical result is achieved by the fact that the section of the casing in the processing zone is made of a material that transmits ultraviolet radiation, in the processing zone around the casing, four ultraviolet lamps with reflectors and reflective screens are installed to reflect the radiation flow. To ensure high uniformity of processing, the gap between the casing and the auger rod is four centimeters.

The essence of the utility model is that the device for processing seeds, containing a hopper mounted on a frame, connected to a casing, at the end of which there is an unloading window, and inside the casing - an auger with a drive from a gear motor with a belt transmission, a control panel, characterized in that the casing in the processing zone is made of a material that transmits ultraviolet radiation, the gap for moving seeds between the casing and the auger rod is four centimeters, four ultraviolet lamps with reflectors and reflective screens made with the possibility of re-reflecting the incoming flow of ultraviolet radiation into the processing zone, are installed at an angle of 90° relative to each other around the casing.

To load seeds, there is a hopper connected to the casing, and an auger inside the casing. To ensure high uniformity of ultraviolet seed treatment, the gap for moving seeds between the casing and the auger rod is four centimeters. To enable the auger to rotate, there is a gear motor and a belt drive. Ultraviolet lamps with reflectors and reflective screens for reflecting the radiation flow are installed parallel to the casing in the processing zone from B to C. A control panel is provided to start and stop the device and control the auger rotation speed. The seeds are moved by the auger from the hopper to the unloading window. The device is made on a frame.

The seed treatment device will be clear from the following description and the accompanying drawings.

Fig. 1 shows a general view of the device for seed processing.

Fig. 2 shows a section of the casing with a screw in the processing zone.

The seed treatment device consists of a hopper 1 (Fig. 1). The hopper 1 is connected to a casing 2 (Fig. 1, 2) inside which there is an auger 3. The part of the casing 2 in the treatment zone in the section from B to C is made of a material that allows ultraviolet radiation to pass through. The auger 3 is designed with the possibility of capturing seeds from the hopper 1 (Fig. 1) and further moving them along the casing 2 (Fig. 1, 2). The drive of the device is a gear motor 4 (Fig. 1) connected to the auger 3 (Fig. 1, 2) by means of a belt drive 5 (Fig. 1). To be able to disinfect the surface of the seeds and stimulate the germination processes, ultraviolet lamps 6 (Fig. 1, 2) with reflectors 7 and reflective screens 8 are provided. Ultraviolet lamps 6 are located around the casing 2 from above and below, as well as on both sides on the sides. The angle of installation between adjacent ultraviolet lamps 6 is 90°. There are four radiation sources in the device. The reflective screen 8 is designed with the possibility of re-reflecting the incoming flow of ultraviolet radiation into the processing zone, and also prevents the dispersion of ultraviolet radiation and its penetration into personnel during operation of the device. The rotation speed of the auger 3 is controlled by the control panel 9 (Fig. 1). The unloading of processed seeds from the casing 2 (Fig. 1, 2) is carried out through the unloading window 10 (Fig. 1). The device is made on the frame 11.

The seed treatment device works as follows:

On the control panel 9 (Fig. 1), the operator sets the rotation frequency of the auger 3 (Fig. 1, 2), which affects the speed of movement of the seeds in the casing 2. During operation of the device, the seeds from the hopper 1 (Fig. 1) are captured by the auger 3 (Fig. 1, 2) and moved along the casing 2 in the direction of the unloading window 10 (Fig. 1). When the seeds are moved along the casing 2 (Fig. 1, 2), they enter the processing zone in the section from B to C, where they are exposed to radiation from the ultraviolet lamps 6. After the processing zone, the seeds are moved by the auger 3 to the unloading window 10 (Fig. 1), from where they are poured out beyond the casing 2 (Fig. 1, 2). If it is necessary to change the level of energy irradiation in the processing zone, the operator changes the rotation frequency of the auger 3, which affects the speed of movement of the seeds and, accordingly, the duration of passage of the seeds through the processing zone. After processing, the seeds are ready for subsequent planting or germination.

The proposed device for seed treatment provides for treatment with ultraviolet radiation energy with high uniformity during the movement of seeds by a screw due to simultaneous ultraviolet radiation in the treatment zone from four sources located on different sides.
