Description

Technical Field

[0001] The utility model relates to a liquid spraying device, in particular to a liquid spraying device used for inactivating plant viruses, belonging to the technical field of plant thermal inactivation and detoxification. Background Art

[0002] At present, the thermal inactivation of plant viruses generally adopts the heat treatment detoxification method, which is carried out by hot water or hot air. The hot water inactivation method uses water bath treatment, which is more effective for dormant buds of plants. That is, by heat treatment detoxification of plant seeds, the viruses in plant tissues are partially inactivated or completely inactivated under high temperature, which can improve the germination survival rate of seeds.

[0003] In the prior art, there is a simple method for promoting the germination of Cistanche deserticola seeds disclosed in publication number CN104126345A, which includes soaking the seeds in hot water at 60-80°C for 3-8 minutes, soaking the seeds in tap water overnight after the seeds are naturally cooled; selecting the unswollen seeds and soaking them in hot water at 60-80°C for 3-8 minutes again, soaking the seeds in tap water overnight after the seeds are naturally cooled; before germinating the seeds, soaking the seeds treated with hot water in 300-700 times diluted high chlorine for 1-3 hours for disinfection; evenly spreading the disinfected seeds on the nursery bed, keeping them fully moist, and germinating them, that is, the prior art discloses an operation method for heat-treating seeds with hot water to achieve virus inactivation. However, in order to make the operation more convenient, a special spraying device is often used to spray hot water on the seeds. For example, in the prior art, a breeding device for agricultural production disclosed in the announcement number CN214961422U uses a water pump to suck out the seedling liquid in the water tank and spray the seedlings in the seedling pot with the seedling liquid through the nozzle. The electric telescopic rod can push the square plate to drive the nozzle to move to evenly spray the seedling liquid on each seedling pot. The device is also capable of spraying liquid on the seeds, replacing the liquid with hot water, and also capable of achieving virus passivation treatment on the seeds. However, in the actual spraying process, only one side of the disk can be sprayed, and the uniformity and comprehensiveness of the spraying cannot be ensured, which will lead to unsatisfactory actual spraying passivation effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The upper and lower ends of the box body 1 are provided with driving slides 5, and the pipe body of the injection pipe 3 is installed on the driving slide 5. The injection pipe 3 moves in the opposite direction of the sliding direction of the upper and lower driving slides 5, and the injection pipe 3 is connected to a plurality of nozzles 32 on the pipe body of the plant seed tray 2, so that a certain amount of plant seeds can be placed in the plant seed tray 2, and hot water of a certain temperature can be sprayed on the upper and lower sides of the plant seed tray 2 through the nozzles 32 connected to the injection pipe 3 to achieve virus passivation of the plant seeds in the tray. At the same time, the injection pipes 3 on the upper and lower sides of the plant seed tray 2 move in opposite directions, thereby forming a staggered spraying, that is, it can achieve uniform spraying of hot water on the upper and lower sides, and can also avoid damage to the plant seeds caused by the counter-position spraying.

[0027] Embodiment 2

[0028] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0029] A box cover 11 is connected to an opening on one side of the box body 1, and supporting feet 12 are connected to the four corners of the bottom end of the box body 1. The plant seed tray 2 can be easily placed in the box body 1 by opening and closing the box cover 11, and the opening of the box body 1 is sealed to ensure that when spraying hot water, the temperature in the box is maintained to ensure the passivation effect on plant viruses, and at the same time, the splashing of the sprayed hot water can be avoided.

[0030] The inner walls on both sides of the box body 1 are fixedly connected to the limiting support strips 15, and the limiting edge strips 23 are connected to the two sides of the plant seed plate 2, and the limiting edge strips 23 are clamped on the upper surface of the limiting support strips 15, so that the plant seed plate 2 can be placed in the box body 1 in a suspended state, and then hot water can be sprayed on the seeds in the pot from the upper and lower sides of the plant seed plate 2.

[0031] The bottom surface of the box body 1 is set as a bottom slope 13, and the inclined ends of the bottom slope 13 converge at the center of the bottom plate of the box body 1. The center of the bottom plate of the box body 1 is connected to a return pipe 14, which can make the sprayed hot water converge on the bottom plate of the box body 1, and the hot water is recovered through the return pipe 14 to be sprayed onto the plant seed tray 2 again, thereby realizing the recycling of hot water and avoiding the accumulation of the sprayed hot water in the box body 1.

[0032] Embodiment 3

[0033] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0034] The plant seed tray 2 includes a tray frame 21, a bottom net 22 and a cover net 24. The bottom net 22 is fixedly connected to the bottom end of the tray frame 21, and the cover net 24 is movably clamped on the upper end of the tray frame 21, so that the plant seed tray 2 has an upper and lower two-layer mesh structure, thereby ensuring that when hot water is sprayed on the plant seeds in the tray from the upper and lower sides, the plant seeds can be prevented from being washed out of the tray.

[0035] The nozzles 32 connected to the body of the spray pipe 3 are evenly distributed, and a telescopic hose 31 is connected to the lower body of the spray pipe 3. The other end of the telescopic hose 31 passes through the box body 1 and is connected to an external hot water delivery pipeline to enable hot water to be delivered to the spray pipe 3. As the spray pipe 3 moves, the telescopic hose 31 can be extended or retracted in length to avoid interference with the movement of the spray pipe 3.

[0036] The driving slide 5 includes a limit sliding frame 51, a slider 52 and a threaded rod 53. The two ends of the limit sliding frame 51 are fixedly connected to the inner walls of the two sides of the box body 1, and a gap is left between the limit sliding frame 51 and the upper and lower sides of the box body 1. The slider 52 is movably arranged in the limit sliding frame 51. The threaded rod 53 is rotatably connected to the two ends of the limit sliding frame 51, and the slider 52 is threadedly sleeved on the rod body of the threaded rod 53. The slider 52 is connected to the middle tube body of the injection pipe 3 so that the slider 52 can drive the injection pipe 3 to move through the rotation of the threaded rod, thereby achieving comprehensive spraying coverage of the plant seed plate 2. In addition, since there is a gap between the limit sliding frame 51 and the upper and lower sides of the box body 1, the sprayed hot water will not accumulate in the limit sliding frame 51, which can facilitate the recovery of hot water for secondary spraying.

[0037] Reverse threads are provided on the rod bodies of the upper and lower threaded rods 53, and a driving stepper motor 4 is fixedly connected to the outer wall of the box body 1, and one end of the two threaded rods 53 extending out of the box body 1 is coaxially connected to the rotating shaft of the driving stepper motor 4. The two driving stepper motors 4 can rotate forward and reverse at a certain frequency, thereby driving the two threaded rods 53 to rotate respectively, and under the action of the reverse threads, the slider 52 can be regularly moved in the opposite direction to achieve staggered and uniform spraying of the upper and lower sides of the plant seed plate 2.

[0038] Working principle: a certain amount of plant seeds are placed in the plant seed tray 2, and hot water of a certain temperature is sprayed on the upper and lower sides of the plant seed tray 2 through the nozzle 32 connected to the injection pipe 3 to achieve virus inactivation of the plant seeds in the tray. The sprayed hot water is gathered on the bottom plate of the box body 1, and the hot water is recovered through the reflux pipe 14 to be sprayed onto the plant seed tray 2 again to achieve the recycling of hot water. The two driving stepper motors 4 rotate forward and reverse at a certain frequency, and then drive the two threaded rods 53 to rotate respectively, and can make the slider 52 move in the opposite direction regularly under the action of the reverse thread, so as to achieve staggered uniform spraying of the upper and lower sides of the plant seed tray 2.
