Description

Technical Field

[0001] This utility model belongs to the field of germination equipment technology, and more specifically, relates to a vertical germination system. Background Technology

[0002] Seed soaking is a process in agricultural planting, referring to the soaking of slow-germinating seeds before sowing. The purpose of soaking is to allow the seeds to absorb water more quickly, reaching a moisture content suitable for normal germination. Dry seeds typically have a moisture content below 15%, exhibiting very weak physiological activity and remaining dormant. After absorbing water, the seed coat swells and softens, and dissolved oxygen enters the cells along with the water. Enzymes in the seed also begin to activate. Due to the action of enzymes, embryo respiration is enhanced, and the insoluble substances stored in the endosperm gradually transform into soluble substances, which are transported to the embryo along with the water. The embryo obtains water, energy, and nutrients, and under suitable temperature and oxygen conditions, the cells begin to divide and elongate, thus enabling the seed to germinate.

[0003] Traditional seed soaking and germination equipment suffers from high residue rates and difficult cleaning. To address this, the applicant disclosed a horizontal germination device in patent CN222750867U. This application includes a frame with a germination tank and a drive mechanism on it. The drive mechanism rotates the germination tank. The germination tank is horizontally positioned and has an axially extending feed trough through which seeds enter. During germination, the germination tank oscillates under the drive mechanism. After germination, the feed trough rotates to the bottom with the germination tank for discharge. This application utilizes a single feed trough on the circumferential wall of the germination tank for both feeding and discharging, resulting in more thorough material discharge and minimizing residue.

[0004] However, this application requires a screw conveyor to transport the material to the trough, which can easily damage the material during the conveying process. Furthermore, a certain amount of material tends to remain inside the screw conveyor, resulting in waste and requiring cleaning, thus increasing labor intensity. Therefore, the industry still needs more diverse and sophisticated designs to address the problems of high residue rates and difficult cleaning in existing organic soaking and germination equipment.

[0017] (2) A vertical germination system of the present invention has a sleeve fitted on the lower part of the cone, and several water filtering holes are opened on the area of ​​the cone covered by the sleeve. In the early stage of seed soaking, the seeds need to absorb a lot of water. At this time, water can be injected into the sleeve and then enter the germination tank body through the water filtering holes to soak the seeds. In the later germination process, the excess water in the germination tank body can flow back into the sleeve through the water filtering holes and then be discharged through the drain outlet at the bottom of the sleeve to prevent the seeds from being continuously soaked in water, which would lead to seed hypoxia, inhibit respiration and metabolism, or even cause seed rot.

[0019] (4) A vertical germination system of the present invention has a supporting column with reinforcing ribs. The other end of the reinforcing ribs is inclined upward and connected to the outer wall of the sleeve. Multiple reinforcing ribs can support the sleeve to further ensure the stability of the germination tank body.

[0020] (5) A vertical germination system of the present invention has a groove formed at the discharge port of the hopper, and a discharge channel is formed between the groove and the conveyor belt of the second conveyor line; the seeds fall from the discharge port of the hopper and accumulate on the second conveyor line, are first spread on the second conveyor line, and then gradually fall into the planting tray below; compared with the traditional instantaneous feeding mode, the present invention adopts a continuous feeding mode, which can effectively improve the flatness of the seeds in the planting tray while realizing quantitative feeding.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] like Figure 1 As shown, a vertical germination system according to this embodiment includes a germination tank body 100, a water supply mechanism 200, and an aeration mechanism 300. The germination tank body 100 is used for soaking and germinating seeds; the water supply mechanism 200 is used for supplying water to the germination tank body 100; and the aeration mechanism 300 is used for aeration of the germination tank body 100.

[0027] Specifically, refer to Figure 2 As shown, the germination tank body 100 is placed vertically, and includes a cylindrical body 110 and a cone 120 connected vertically. The bottom of the cone 120 forms a discharge port, and a discharge valve is connected to the discharge port.

[0028] In some embodiments, a cover 160 is provided at the top opening of the cylinder 110. At the same time, an overflow port 111 is provided near the top of the cylinder 110.

[0029] Preferably, the cover 160 includes two top covers of different sizes. The larger top cover can be fixedly mounted on the top of the cylinder 110, while the smaller top cover is movably mounted on the top of the cylinder 110, for example, by hinge, to facilitate opening and closing operations.

[0030] In this embodiment, as a specific implementation of the water supply mechanism 200, the water supply mechanism 200 includes a spray assembly 210 and a cleaning assembly 220 disposed inside the cylinder 110.

[0031] refer to Figure 7As shown, the spray assembly 210 includes a spray ring pipe 211, spray heads 212 arranged circumferentially along the spray ring pipe 211, and a first connecting rod 213. Multiple spray heads 212 can be provided, each facing downwards, for spraying the seeds inside the germination tank body 100 to maintain a certain humidity. Multiple first connecting rods 213 can also be provided, mainly for connecting to the cylinder 110.

[0032] refer to Figure 8 As shown, the cleaning assembly 220 includes a cleaning ring pipe 221, a cleaning head 222 arranged circumferentially along the cleaning ring pipe 221, and a second connecting rod 223. Multiple cleaning heads 222 can be provided, and each cleaning head 222 is positioned facing the inner wall of the cylinder 110 to rinse residual material on the inner wall of the cylinder 110. Multiple second connecting rods 223 can also be provided, mainly for connecting to the cylinder 110.

[0033] Specifically, in this embodiment, the first connecting rod 213 and the second connecting rod 223 are both in the shape of a ring and are distributed in three at equal intervals, and at least two spray heads 212 / cleaning heads 222 are provided between two adjacent first connecting rods 213 / second connecting rods 223.

[0034] This embodiment of a vertical germination system features a germination tank body 100 that is placed vertically with a conical lower section, allowing for material feeding using gravity. This feeding method effectively reduces seed residue after discharge, eliminates the need for additional conveying mechanisms, and prevents material damage from compression. Furthermore, the spray ring pipe 211 ensures uniform wetting of the seeds within the germination tank body 100, while the cleaning ring pipe 221 rinses the inner wall of the tank, enabling quick and convenient removal of residual seeds.

[0035] It is also worth mentioning that the first connecting rod 213 and the second connecting rod 223 can be directly welded to the inner wall of the cylinder 110; or mounting ears can be provided on the inner wall of the cylinder 110 in advance, and the first connecting rod 213 and the second connecting rod 223 can be detachably connected to the corresponding mounting ears by bolts; or other connection methods in the prior art, which are not specifically limited here.

[0036] In some embodiments, the spray assembly 210 is entirely located below the cleaning assembly 220, and the diameter of the spray ring pipe 211 is smaller than the diameter of the cleaning ring pipe 221. Specifically, the diameter of the spray ring pipe 211 is 1 / 4 to 1 / 2 of the inner diameter of the cylinder 110. Preferably, it is 1 / 3, to ensure that the spray range covers the entire germination tank body 100.

[0037] Furthermore, the first connecting rod 213 and the second connecting rod 223 can be hollow and interconnected with the corresponding annular pipes. Simultaneously, nozzles are mounted on the first connecting rod 213 and the second connecting rod 223. This design further increases the spray range of the spray assembly 210 and the rinsing range of the cleaning assembly 220.

[0038] refer to Figure 5 , Figure 6 As shown, in some optional embodiments, a sleeve 130 is fitted onto the lower part of the cone 120, and a plurality of filter holes 121 are formed in the area of ​​the cone 120 covered by the sleeve 130. Of course, the sleeve 130 needs to have a clearance opening similar to the discharge port at the bottom of the cone 120; and the connection between the clearance opening and the discharge port is designed to be sealed so that the area enclosed between the sleeve 130 and the cone 120 can form a sealed body. Meanwhile, a drain port is formed at the bottom of the sleeve 130.

[0039] Preferably, the filter hole 121 is a long strip hole or a waist-shaped hole with a diameter of 2mm*20mm. On the one hand, it can stop the seeds from falling through the filter hole 121, and on the other hand, it can ensure a greater filtration effect.

[0040] In addition, a viewing window 140 is provided on the sleeve 130 to facilitate observation of its inner wall.

[0041] In this embodiment, a vertical germination system is used. During the initial soaking stage, the seeds require a large amount of water. Water is injected into the sleeve 130 and then flows through the filter hole 121 into the germination tank body 100 to soak and absorb water. During the later germination process, excess water in the germination tank body 100 flows back into the sleeve 130 through the filter hole 121 and is then discharged through the drain at the bottom of the sleeve 130. This prevents continuous soaking from causing seed hypoxia, inhibiting respiration and metabolism, or even causing seed rot. Simultaneously, the spray assembly 210 can be periodically activated during germination to spray the seeds, maintaining environmental humidity and accelerating germination.

[0042] In some alternative implementations, nutrient solution may be added to the germination tank body 100 during the soaking and / or germination process.

[0043] refer to Figure 2 , Figure 3 As shown, in some other embodiments, the water supply mechanism 200 also includes a main water inlet pipe 230, one end of which is connected to a water source via a water pump, and the other end extends into the sleeve 130. Additionally, the main water inlet pipe 230 is provided with two branch water inlet pipes 240, which are used to supply water to the spray assembly 210 and the cleaning assembly 220, respectively.

[0044] In addition, the overflow port 111 on the cylinder 110 is connected to the main drain pipe 250, and the drain port on the sleeve 130 is connected to the main drain pipe 250 through the branch drain pipe 260.

[0045] Furthermore, the main water inlet pipe 230, the branch water inlet pipe 240, and the branch drain pipe 260 are all equipped with control valves 270 to facilitate the on / off operation of the water supply.

[0046] like Figure 1 , Figure 6 As shown, in one specific implementation of the aeration mechanism 300, the aeration mechanism 300 includes an aeration pipe 310, one end of which is connected to a blower 320, and the other end extends into the cone 120 and is connected to an aeration head 330.

[0047] Of course, the aeration pipe 310 can also be equipped with a control valve 270. At the same time, a mounting seat 150 for installing various pipes is provided on the outer peripheral wall of the cylinder 110.

[0048] refer to Figure 1 As shown, as a further improvement to the vertical germination system of this embodiment, based on the above embodiment, a support mechanism 400 for supporting the germination tank body 100 is also included.

[0049] Specifically, refer to Figure 9 , Figure 10 , Figure 11 As shown, the support mechanism 400 includes a plurality of support columns 410, each support column 410 having a mounting notch 411 at its top. The mounting notch 411 includes a vertically arranged first mounting portion 4111 and an inclinedly arranged second mounting portion 4112. The first mounting portion 4111 is used for welding to the outer wall of the cylinder 110, and the second mounting portion 4112 is used for welding to the outer wall of the cone 120, thereby increasing the connection strength between the support column 410 and the germination tank body 100 and ensuring the support effect.

[0050] In some embodiments, four support columns 410 are arranged in a rectangular pattern, and conduits 420 are provided between adjacent support columns 410. Specifically, intermediate connecting blocks 430 may be pre-welded onto the support columns 410, and the ends of the conduits 420 are installed on the corresponding intermediate connecting blocks 430. At the same time, both the support columns 410 and the conduits 420 are provided with wire-passing holes 421.

[0051] Furthermore, the support column 410 is provided with reinforcing ribs 440, the other end of which is inclined upward and connected to the outer wall of the sleeve 130, for example, by welding. With this design, multiple reinforcing ribs 440 can support the sleeve 130 to further ensure the stability of the support for the germination tank body 100.

[0052] refer to Figure 12 As shown, as another improved version of the vertical germination system in this embodiment, based on the above embodiment, it also includes a feeding mechanism 500 for spreading the germinated seeds.

[0053] Specifically, refer to Figure 13 As shown, the feeding mechanism 500 includes a first conveyor line 510 and a spreading unit 520. The first conveyor line 510 is used to convey the planting tray 600. The spreading unit 520 is located above the first conveyor line 510 and is used to quantitatively and evenly spread the seeds falling from the germination tank body 100 into the moving planting tray 600.

[0054] refer to Figure 14 , Figure 15 As shown, the paving unit 520 includes a mounting frame 521, a hopper 522 mounted on the mounting frame 521, and a second conveyor line 523. The hopper 522 is located above the second conveyor line 523. The inlet of the hopper 522 is connected to the outlet valve at the bottom of the germination tank body 100 via a flange 527. A slot 5221 is formed at the outlet of the hopper 522, forming a discharge channel between the slot 5221 and the conveyor belt of the second conveyor line 523.

[0055] Specifically, the hopper 522 has a cone-shaped structure that is wider at the top and narrower at the bottom. Its discharge port is an opening formed by the bottom of the peripheral wall of the hopper 522, and the slot 5221 is opened on the peripheral wall at the rear. Here, front and back are determined by the conveying direction of the second conveyor line 523. The end closer to the beginning of the second conveyor line 523 is the front, and the end closer to the end of the second conveyor line 523 is the rear.

[0056] In some embodiments, to ensure that seeds can only be discharged from the discharge channel, the gap between the portion of the bottom of the peripheral wall of the hopper 522 without the slot 5221 and the conveyor belt of the second conveyor line 523 is generally no more than 2.5 mm. At the same time, to prevent interference between the bottom of the peripheral wall and the conveyor belt, a certain distance must be maintained between them. Preferably, this distance is 0.5-2.5 mm, for example, 0.8 mm, 1.4 mm, 2.2 mm, etc.

[0057] Specifically, in this embodiment, the discharge port of the hopper 522 is a rectangular structure formed by four side plates. The slot 5221 is located at the bottom of the side plate near the end of the second conveyor line 523, serving as the sole outlet for the seeds within the hopper 522. While there are gaps between the bottoms of the other three side plates and the second conveyor line 523, these gaps are smaller than the diameter of the germinated seeds and are insufficient for the seeds to leak out.

[0058] During operation, the germinated seeds fall from the germination tank body 100 into the feeding hopper 522. Initially, since the second conveyor line 523 is stationary, the seeds accumulate in the storage space enclosed by the feeding hopper 522 and the second conveyor line 523. As the second conveyor line 523 starts, it carries some seeds out of the storage space through the discharge channel and continues to transport them. These seeds eventually fall from the end of the second conveyor line 523. At this time, the planting tray 600 located below receives the seeds falling from the second conveyor line 523 under the transport of the first conveyor line 510.

[0059] In some embodiments, after a planting tray 600 is leveled, the second conveyor line 523 rotates in the opposite direction to send the seeds stuck to the end of the arc segment of the second conveyor line 523 back to the horizontal conveying surface, preventing the seeds stuck to the end of the second conveyor line 523 from falling to the ground or onto the first conveyor line 510 after the planting tray 600 leaves below the second conveyor line 523.

[0060] This embodiment of a vertical germination system involves the quantitative output of germinated seeds through a discharge channel, followed by flattening on a second conveyor line 523. The seeds then continuously fall from the end of the second conveyor line 523. Compared to the traditional instantaneous feeding mode, the sequential feeding mode used in this embodiment effectively improves the flatness of the seeds within the planting tray 600.

[0061] In some embodiments, the hopper 522 is provided with an adjusting plate 524, which covers the slot opening 5221. Simultaneously, the adjusting plate 524 has several oblong holes, and the hopper 522 has corresponding fastening holes; connecting bolts pass through the corresponding oblong holes and fastening holes in sequence to achieve an adjustable connection between the adjusting plate 524 and the hopper 522.

[0062] In this embodiment, by setting an adjustment plate 524 at the slot 5221, the height of the discharge channel can be flexibly adjusted to meet the uniform spreading requirements of seeds of different thicknesses.

[0063] In other embodiments, guide plates 525 are provided on both sides of the second conveyor line 523 near the end, which are used to guide and limit the seeds during the conveying process.

[0064] Meanwhile, a scraper 526 is provided at the end of the second conveyor line 523, and the scraper 526 has an inclined scraping surface for timely cleaning of seeds adhering to the second conveyor line 523.

[0065] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
