Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production, in particular to a dry-type germination box with a sterilization function. Background Art

[0002] A dry germination chamber is a device that uses dry (non-hydroponic or soil) methods to promote seed germination and seedling growth by precisely controlling environmental parameters such as temperature, humidity, and light. As a place and facility for seed germination and growth, the germination chamber provides the appropriate temperature, moisture, and growth space for seedlings.

[0003] In the Chinese utility model patent application number 201120421431.7, a rice seed germination box is proposed. A sprinkler is installed on the top of the germination box, and the sprinkler is used to intermittently spray constant temperature water on the vertically stacked seed trays to maintain a moist growth environment for the rice seeds and keep the inside of the germination box within a suitable temperature range. The main problems of this patent are: there are no facilities inside the germination box to effectively avoid the production and spread of fungi. In fact, the relatively closed growth environment inside the germination box leads to a decrease in the oxygen content inside the germination box, which promotes the reproduction of anaerobic bacteria. At the same time, the setting of the top spray structure causes the fungal clusters produced inside different seed trays to spread and reproduce rapidly through the spray liquid, ultimately affecting the quality and production efficiency of the seed sprouts in the entire germination box. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a dry germination box with a sterilization function, which solves the problem that large-scale fungal infection is easy to occur in the germination box, realizes effective sterilization inside the germination box and inhibits the generation and spread of fungi.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A dry germination box with a sterilization function comprises a closed box, wherein the interior of the closed box is divided into a germination chamber and an environmental control chamber arranged side by side on the left and right by a partition plate, the upper space and the lower space of the germination chamber and the environmental control chamber are interconnected, a plurality of seed tray supports equidistantly stacked in a vertical direction are arranged inside the germination chamber, a seed tray is placed on each tray support, and a sterilization component, a heating component and a circulating humidification component are arranged in the environmental control chamber.

[0007] The following is a further optimization of the above technical solution by the present invention:

An atomizer for oscillating and atomizing the water in the water tank is installed inside the water tank. The guide air duct is connected to the lower space of the germination bin through the water mist inlet at the bottom of the partition partition. A circulating fan is installed in the upper space of the environmental control bin, and the air inlet of the circulating fan is connected to the upper space of the germination bin.

[0009] Further optimization: a dividing slot partition is provided on the bottom wall of the environmental control warehouse, and an inclined guide plate is provided above the dividing slot partition. The inclined upper end of the guide plate is fixed on the side wall of the partition partition, and the inclined lower end of the guide plate is located directly above the water tank. A guide air duct is formed between the dividing slot partition, the partition partition and the guide plate.

[0010] Further optimization: the sterilization assembly includes multiple groups of sterilization tube groups that are equidistantly stacked, and the sterilization tube groups are arranged between the circulating fan and the guide plate. Each sterilization tube group includes several ultraviolet sterilization tubes arranged side by side.

[0011] Further optimization: the heating component includes a fin heating tube bundle arranged in a horizontal direction, and the fin heating tube bundle is arranged between the sterilization component and the guide plate.

[0017] The utility model adopts the above technical solution, which has the following beneficial effects:

[0018] The utility model sets a circulating moisturizing component in the environmental control chamber, atomizes water and blows it through each layer of seed tray from bottom to top, and then uses the sterilization component in the environmental control chamber to sterilize the circulating water mist, which solves the defect that large-scale fungal infection is easy to occur inside the germination box, thereby achieving effective sterilization and the effect of inhibiting the generation and spread of fungi in the germination box.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1-4 As shown together, a dry germination box with a sterilization function includes a closed box 1. The interior of the closed box 1 is divided into a germination bin 2 and an environmental control bin 3 arranged side by side on the left and right by a partition partition 11. The upper space and the lower space of the germination bin 2 and the environmental control bin 3 are interconnected. The interior of the germination bin 2 is provided with a plurality of seed tray supports 4 equidistantly stacked in the vertical direction. A seed tray 41 is placed on each tray support 4. The environmental control bin 3 is provided with a sterilization component 5, a heating component 6 and a circulating humidification component 7.

[0030] In this embodiment, the environmental control chamber 3 is used to process the air environment of the circulating air.

[0031] In this embodiment, the seed tray 41 adopts a shallow tray structure with a mesh structure at the bottom, which is used to carry the germinated seeds and allows the circulating air with water mist to flow smoothly through the mesh holes at the bottom and the gaps between the seeds.

[0032] Compared with the traditional wet water spray germination box, the circulating air in the present invention blows from bottom to top, and less water condenses on the surface of the seeds. Each seed tray 41 will not produce water cross-flow, thereby avoiding the rapid spread of fungi caused by the movement of bacterial plaque with water flow.

[0033] like Figure 3-Figure 5 As shown together, the circulating humidification component 7 includes a guide air duct 71 and a water tank 72 arranged side by side in the lower space of the closed box 1. An atomizer 73 for oscillating and atomizing the water in the water tank 72 is installed inside the water tank 72. The guide air duct 71 is connected to the lower space of the germination bin 2 through the water mist inlet 12 at the bottom of the partition plate 11. A circulating fan 74 is installed in the upper space of the environmental control bin 3, and the air inlet of the circulating fan 74 is connected to the upper space of the germination bin 2.

[0034] In this embodiment, the atomizer 73 can be an ultrasonic atomizer that can be purchased on the market.

[0035] In this embodiment, the atomizer 73 uses ultrasonic waves of a certain band to generate rapid oscillations near the liquid surface of the water tank 72 and produce a large amount of water mist. The generated water mist replenishes moisture for the circulating air and the inside of the closed box 1, so that the humidity inside the closed box 1 is not lower than the set value suitable for the growth of seed buds.

[0036] Among them, a dividing partition 13 is provided on the bottom wall of the environmental control warehouse 3, and an inclined guide plate 14 is provided above the dividing partition 13. The inclined upper end of the guide plate 14 is fixed on the side wall of the partition partition 11, and the inclined lower end of the guide plate 14 is located directly above the water tank 72. A guide air duct 71 is formed between the dividing partition 13, the partition partition 11 and the guide plate 14.

[0037] like Figure 3 and Figure 5 As shown together, the sterilization assembly 5 includes multiple groups of sterilization tube groups that are equidistantly stacked. The sterilization tube groups are arranged between the circulation fan 74 and the guide plate 14. Each sterilization tube group includes a plurality of ultraviolet sterilization tubes arranged side by side.

[0038] In this embodiment, after the circulating fan 74 is turned on, the ultraviolet sterilization tube generates ultraviolet rays of a certain power within a certain light band to inactivate fungi carried in the circulating air, while also inhibiting the reproduction of fungi in the closed box 1.

[0039] Moreover, the heating component 6 includes a finned heating tube bundle arranged in a horizontal direction, and the finned heating tube bundle is provided between the sterilization component 5 and the guide plate 14 .

[0040] In this embodiment, a temperature sensor (not shown in the figure) is provided in the environmental control chamber 3. The sensing end of the temperature sensor monitors the temperature of the circulating air. When the monitored temperature is lower than the preset temperature, the finned heating tube bundle can provide heat of appropriate power to the circulating air, so that the overall temperature inside the closed box 1 is maintained within a suitable range suitable for the growth of seed buds.

[0041] like Figure 3 As shown, a collecting chamber 15 is provided between the upper end of the partition partition 11 and the top wall of the closed box 1, and a water mist outlet 16 connected to the germination bin 2 is provided on the side wall of the collecting chamber 15. The water mist outlet 16 is provided with multiple groups of water baffles 17 arranged side by side, and the air inlet of the circulating fan 74 is connected to the inside of the collecting chamber 15.

[0042] In this embodiment, each water retaining plate 17 is vertically arranged, and has a V-shaped cross section with its opening facing the windward side.

[0043] In this embodiment, the setting of the water baffle 17 can rapidly deflect the direction of the circulating air passing through the water baffle 17. At the same time, since the density of water mist in the circulating air is greater than that of air, under the influence of inertia and centrifugal force, the circulating air is not easy to bend quickly with the low-density air when changing wind direction. Instead, it will hit the water baffle 17 and condense and converge on the water baffle 17, and finally flow along the water baffle 17 and the partition partition 11 to the bottom of the germination bin 2, and be discharged from the closed box 1 through the automatic drain valve 21.

[0044] like Figure 3 and Figure 5 As shown, an automatic water replenishment valve 75 and a maintenance drain valve 76 are installed on the side wall of the water tank 72.

[0045] In this embodiment, the automatic water replenishing valve 75 is used to automatically replenish the water in the water tank 72 so that the liquid level is always maintained within a fixed range.

[0046] In this embodiment, the maintenance drain valve 76 is used to drain the water tank 72 during maintenance.

[0047] like Figure 1-Figure 3 As shown together, a warehouse door 18 is installed on the front wall of the closed box 1, and the position of the warehouse door 18 corresponds to the position of the germination warehouse 2. An inspection door 19 is installed on the side wall of the closed box 1, and the position of the inspection door 19 corresponds to the position of the environmental control warehouse 3.

[0048] In this embodiment, the door 18 is provided for taking in and placing the seed tray 41 .

[0049] In this embodiment, the provision of the inspection door 19 facilitates inspection of the interior of the environmental control chamber 3 .

[0050] like Figure 1 and Figure 2 As shown in the figure, a fresh air inlet 8 is installed on the top of the closed box 1, and the fresh air inlet 8 is connected to the upper space of the germination warehouse 2. An exhaust pipe 9 is installed on the upper end of the front wall of the closed box 1, and the exhaust pipe 9 is connected to the upper space of the environmental control warehouse 3.

[0051] In this embodiment, the fresh air inlet 8 is arranged in the low-pressure area before the circulation fan 74 , and the exhaust pipe 9 is arranged in the high-pressure area after the circulation fan 74 .

[0052] In this embodiment, the fresh air outlet 8 is in the shape of an inverted trumpet.

[0053] In this embodiment, an air filter (not shown in the figure) can be provided at the top opening of the fresh air outlet 8.

[0054] In this embodiment, the provision of the fresh air inlet 8 can absorb a portion of fresh air to replenish the oxygen in the germination bin 2, so as to inhibit the growth of anaerobic bacteria.

[0055] In this embodiment, the exhaust pipe 9 is provided to discharge the excess gas generated by the fresh air replenishment in the environmental control chamber 3 .

[0056] like Figure 2 and Figure 3 As shown in the figure, an automatic drain valve 21 is installed at the lower end of the germination bin 2.

[0057] The process of using a germination box to germinate seeds is as follows:

[0058] In the first step, the seeds to be germinated are evenly spread on the seed tray 41 , and the door 18 is opened. The seed tray 41 with the seeds spread thereon is placed on the seed tray support 4 , and then the door 18 is closed.

[0059] In the second step, the automatic water replenishing valve 75 is started to replenish the water in the water tank 72 to a predetermined liquid level, and to make the liquid level slightly higher than the atomizer 73.

[0060] The third step is to turn on the circulating fan 74. The circulating air enters the environmental control warehouse 3 from the air outlet of the circulating fan 74, and passes through the ultraviolet sterilization tube and the fin heating tube bundle in turn. Then, under the guidance of the guide plate 14, it passes near the atomizer 73, and finally enters the lower space of the germination warehouse 2 through the guide air duct 71 and the water mist inlet 12.

[0061] In the fourth step, the circulating air passes from the lower space of the germination bin 2 through the multi-layer seed tray 41 from bottom to top to reach the upper space of the germination bin 2, and then enters the collecting chamber 15 through the water baffle 17. The circulating air in the collecting chamber 15 enters the environmental control bin 3 through the circulating fan 74.

[0062] In the fifth step, the ultraviolet sterilization tube is turned on to sterilize the fungi carried in the circulating air and inhibit the spread and reproduction of the fungi.

[0063] In the sixth step, the finned heating tube bundle is turned on to heat the low-temperature circulating air to ensure that the temperature of the circulating air and the temperature inside the closed box 1 are both within a temperature range suitable for the growth of the buds.

[0064] In the seventh step, the atomizer 73 is turned on to oscillate and atomize the water in the water tank 72 and generate a large amount of water mist near the atomizer 73.

[0065] In the eighth step, when the circulating air passes through the vicinity of the atomizer 73 , a large amount of water mist generated by the atomizer 73 enters the germination bin 2 along with the circulating air.

[0066] In the ninth step, when the circulating air flows through the seed tray 41, the small water droplets in the water mist are blocked by the mesh structure at the bottom of the seed tray 41 and the seeds, collide with the seed tray 41 and the seeds, and condense on the seed tray 41 and the seeds, providing moisture for the growth of the seed buds.

[0067] In the tenth step, the excess water mist reaches the top of the germination bin 2 with the circulating air, condenses on the water baffle 17 and flows to the bottom of the germination bin 2 along the partition plate 11, and is finally discharged from the closed box 1 through the automatic drain valve 21.

[0068] After the seeds in the seed tray 41 complete the growth cycle in the germination chamber 2, the germination box stops operating and the seed tray 41 is taken out through the chamber door 18 to complete the production process.

[0069] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
