Description

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

A device for ultraviolet treatment of seeds is known [RU 206252 Ul, A01C 1/00 (2021.05), 02.09.2021]. The device contains: a hopper, a belt conveyor with an electric drive, a distribution conveyor with an electric drive, a source of ultraviolet radiation with a parabolic reflector, a frequency converter.

The disadvantages of the device include the inability to mix the seeds during ultraviolet irradiation. The absence of sides along the edge of the conveyor to prevent seed spillage.

A device for ultraviolet irradiation of bulk materials is known [RU 2537500 C2, A23 B9/06 (2006.01), 10.01.2015]. The design of the device includes: a body, a drum, ultraviolet lamps, and a dosing hopper.

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

A device for pre-sowing treatment of seeds of various agricultural crops is known [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 device 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. As a result of the rotation of the drum with the processed material, ultraviolet lamps can be damaged.

The closest solution in terms of technological essence and achieved effect is a device for seed disinfection [RU 2792155 C1, A01C 1/02 (2022.08), 17.03.2023]. The device consists of a dosing hopper, a tray, a vibrator, a frequency converter, shock absorbers, ultraviolet lamps, parabolic reflectors, a fan, a casing, an ultraviolet radiation intensity sensor, and a frame.

The device for disinfecting seeds acts as a periodic action unit. The disadvantages of the device include low productivity.

The objective of the utility model is to ensure disinfection of seeds using ultraviolet radiation, and the ability to change the dose of seed irradiation in the treatment zone by using partitions.

The technical result is achieved by the fact that the seeds are disinfected by irradiation with a short-wave ultraviolet spectrum; to be able to regulate the irradiation dose by changing the speed of passage of the seed mass in the irradiation zone, three pairs of partitions are installed on the surface of the vibration conveyor.

The essence of the utility model is that in order to implement the specified task, the proposed device for disinfecting seeds is made from a hopper-dispenser, a tray, a first pair of partitions, a second pair of partitions, a third pair of partitions, a vibrator, a control panel, shock absorbers, ultraviolet lamps, a reflector, a storage hopper, and a frame.

In this case, the device for disinfecting seeds is necessary to reduce the overall microbial contamination and disinfect the surface of seeds from mold and fungi. A hopper-dispenser is provided for loading and dosing seeds, and a tray is provided for moving seeds. The first pair of partitions, the second pair of partitions and the third pair of partitions are mounted on the surface of the tray. The partitions are designed to slow down the movement of the seed mass in the processing zone. Each pair of partitions prevents the free movement of the seed layer across the entire width of the tray; seed movement is possible only through an opening in the center of the pair of partitions. A vibrator is provided to implement vibration oscillations of the tray. A control panel is provided to change the operating modes of the vibrator. The tray is mounted on shock absorbers. Ultraviolet lamps with a reflector are located above the tray. A storage bin is located under the tray. The storage bin is designed to accumulate processed seeds. The device is made on a frame.

The device for seed disinfection will be clear from the following description and the attached drawings.

Fig. 1 shows a general view of the device for disinfecting seeds. Fig. 2 shows a top view of the tray.

The device for disinfecting seeds consists of a hopper-dispenser 1 (Fig. 1, 2). Under the hopper-dispenser 1 there is a tray 2 with a first pair of partitions 3 (Fig. 2), a second pair of partitions 4 and a third pair of partitions 5. The pairs of partitions can be installed in the following combinations: only the second pair of partitions 4, the second pair of partitions 4 in combination with the first pair of partitions 3, and together the first pair of partitions 3 with the second pair of partitions 4 and the third pair of partitions 5. The vibrator 6 (Fig. 1) is designed with the possibility of operating in different modes. The operating modes of the vibrator 6 are controlled by means of the control panel 7. The tray 2 (Fig. 1, 2) is designed to receive vibration oscillations from the vibrator 6 (Fig. 1) and is mounted on shock absorbers 8. The ultraviolet lamps 9 are located inside the reflector 10. The reflector 10 is designed to form a flow of directed radiation from the ultraviolet lamps 9 into the processing zone. Radiation from the ultraviolet lamps 9 is fed into the processing zone onto the seeds. After processing, the seeds are fed into the storage bin 11 under the tray 2 (Fig. 1, 2). The frame 12 (Fig. 1) is designed to be able to mount the equipment.

The device for disinfecting seeds operates as follows. The operator installs pairs of partitions on the tray 2 (Fig. 1, 2) taking into account the following possible combinations: only the second pair of partitions 4 (Fig. 2), the second pair of partitions 4 in combination with the first pair of partitions 3, and together the first pair of partitions 3 with the second pair of partitions 4 and the third pair of partitions 5. Each pair of partitions is mounted on the surface of the tray 2 (Fig. 1, 2) with an opening in the center and the possibility of extraction from the tray 2.

By means of the control panel 7 (Fig. 1) the operator selects the operating mode of the vibrator 6. The seeds are fed into the hopper-dispenser 1 (Fig. 1, 2). From the hopper-dispenser 1 the seeds are fed in doses to the tray 2. By means of the vibrator 6 (Fig. 1) vibrations are imparted to the tray 2 due to which the seeds are moved to the processing zone up to the ultraviolet lamps 9. The required speed of movement of seeds on the tray 2 (Fig. 1, 2) is set by the corresponding operating mode of the vibrator 6 (Fig. 1) and the number of installed pairs of partitions in the processing zone on the surface of the tray 2 (Fig. 1, 2). The operation of the device in the case of using all pairs of partitions will proceed as follows.

During the movement of seeds on the surface of tray 2, upon reaching the first pair of partitions 3 (Fig. 2), the movement of the seed mass will slow down due to accumulation at the walls and uniform passage through the opening in the center of the first pair of partitions 3, then the seed mass will be uniformly distributed across the width of tray 2 (Fig. 1, 2). With further movement, the seed mass will slow down due to accumulation at the walls and uniform passage through the opening in the center of the second pair of partitions 4 (Fig. 2), then the seed mass will be uniformly distributed across the width of tray 2 (Fig. 1, 2). With further movement, the seed mass will slow down due to accumulation at the walls and uniform passage through the opening in the center of the third pair of partitions 5 (Fig. 2), then the seed mass will be uniformly distributed across the width of tray 2 (Fig. 1, 2) and move in the direction of the storage bin 11 (Fig. 1).

The operation of the device in case of using two pairs of partitions will proceed as follows. In the process of movement of seeds on the surface of tray 2, upon reaching the first pair of partitions 3 (Fig. 2), the movement of the seed mass will slow down due to accumulation at the walls and uniform passage through the opening in the center of the first pair of partitions 3, then the seed mass will be uniformly distributed across the width of tray 2 (Fig. 1, 2). With further movement, the seed mass will slow down due to accumulation at the walls and uniform passage through the opening in the center of the second pair of partitions 4 (Fig. 2), then the seed mass will be uniformly distributed across the width of tray 2 (Fig. 1, 2) and move in the direction of the storage bin 11 (Fig. 1).

The operation of the device in the case of using one pair of partitions will proceed as follows. During the movement of seeds on the surface of tray 2, upon reaching the first pair of partitions 3 (Fig. 2), the movement of the seed mass will slow down due to accumulation at the walls and uniform passage through the opening in the center of the first pair of partitions 3, then the seed mass will be uniformly distributed across the width of tray 2 (Fig. 1, 2) and will move in the direction of the storage bin 11 (Fig. 1).

During the movement of seeds, the reflector 10 directs the radiation flow from the ultraviolet lamps 9 to the seeds in the processing zone. On the tray 2 (Fig. 1, 2), the seeds are irradiated with ultraviolet lamps 9 and as a result, disinfection and stimulation of seed germination are carried out. After processing, the seeds are ready for subsequent planting or germination.

The proposed device for disinfecting seeds provides the ability to change the dose of seed irradiation in the treatment zone by using partitions on the surface of the tray.
