Description

Technical Field

[0001] This utility model belongs to the technical field of germination equipment, and more specifically, relates to an aeration device for a vertical germination tank. 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] Germination tanks, as commonly used seed soaking equipment, are generally equipped with an aeration system. This system actively introduces air or oxygen into the tank, optimizing the microenvironment and maintaining dissolved oxygen concentration—crucial conditions for seed germination and metabolism. Furthermore, aeration improves the uniformity of temperature and nutrient solution within the tank. Additionally, the bubbles generated during aeration slightly suspend the seeds, preventing them from being compressed due to prolonged stacking, which could hinder radicle growth and even affect subsequent feeding operations.

[0004] refer to Figure 8 As shown, existing aeration systems typically place the aeration heads near the bottom of the tank to achieve aeration within the tank. However, this aeration method creates a significant dead zone between the aeration heads and the discharge port. Therefore, providing an aeration device that can effectively reduce this dead zone is of significant practical importance for seed soaking and feeding operations. Utility Model Content

[0005] The problem to be solved In view of at least some of the problems existing in the prior art, this utility model proposes an aeration device for a vertical germination tank. The purpose is to solve the problem that existing aeration devices for germination tanks have aeration dead corners at the bottom of the tank and in the feeding area, which cause the seeds to become entangled and clumped together in the aeration dead corners of the feeding area after germination, resulting in the inability to feed smoothly.

[0006] Technical solution To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model provides an aeration device for a vertical germination tank, comprising a germination tank body and an aeration mechanism for aerating the germination tank body. The germination tank body includes a cylindrical body and a conical body connected vertically. The bottom of the conical body forms a discharge port, and the discharge port is connected to a discharge valve through a flange pipe. A sleeve is fitted around the lower part of the cone, forming a transition space between the sleeve and the cone; The cone has several through holes in the area covered by the sleeve, and the bottom of the sleeve has an outlet. The aeration mechanism includes several aeration heads arranged in a ring within the transition space, and each aeration head is connected to an aeration pipe; the free end of the aeration pipe passes through a sleeve and is connected to an aeration fan.

[0007] In some embodiments, the flange pipe is provided with a plurality of air blowing holes arranged in a ring, the air blowing holes are connected to an air pump through a pipe, and the air pump is located above the air blowing holes.

[0008] In some embodiments, the bottom of the sleeve is provided with a vibration source for driving the discharge port of the germination tank body to vibrate.

[0009] In some embodiments, the through hole is an elongated hole or a waist-shaped hole, and the width of the through hole does not exceed 3mm.

[0010] In some embodiments, the size of the through hole is (1.8-2.2) mm * (16-24) mm.

[0011] In some embodiments, three aeration heads are provided in an annular shape, and a control valve is installed in the area of ​​the aeration pipe located outside the transition space.

[0012] In some embodiments, the germination tank body is also connected to a support mechanism. The support mechanism includes a plurality of support columns, each support column having a mounting notch at its top. The mounting notch includes a first mounting portion arranged vertically and a second mounting portion arranged at an angle. The first mounting part is used for welding to the outer wall of the cylinder, and the second mounting part is used for welding to the outer wall of the cone.

[0013] In some embodiments, the supporting columns are arranged in a rectangular pattern and there are four columns, with conduits between adjacent supporting columns; The conduit is connected to the corresponding support column via an intermediate connecting block, and both the support column and the conduit are provided with wire passage holes.

[0014] In some embodiments, the support column is provided with reinforcing ribs, and the other end of the reinforcing ribs is inclined upward and connected to the outer wall of the sleeve to support the sleeve.

[0015] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: (1) An aeration device for a vertical germination tank according to the present invention, by setting a sleeve, a transition space can be formed between the sleeve and the cone; the aeration head is set in the transition space and aeration is performed on the germination tank body through the through hole on the cone. With this design, since the aeration head will not block the feed port, the aeration head can be set closer to the bottom of the germination tank body, thereby effectively reducing the aeration dead zone in the bottom area and ensuring the smoothness of the subsequent feed.

[0016] (2) An aeration device for a vertical germination tank of the present invention has several air blowing holes arranged in a ring on the flange tube. When feeding, air is blown into the flange tube through the air blowing holes. The airflow is used to disturb the seeds accumulated in the flange tube. In addition, the aeration head disturbs the seeds above the flange tube, which can further ensure the smoothness of feeding and effectively avoid the situation where the seeds are piled up and cannot be discharged.

[0017] (3) An aeration device for a vertical germination tank according to the present invention has a vibration source at the bottom of the sleeve. When the vibration source vibrates, it drives the tank wall to vibrate, which promotes the feeding of seeds in the flange tube and also prevents the accumulation of seeds.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] 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.

[0022] As mentioned in the background section, existing aeration devices are prone to aeration dead zones at the bottom of the tank and in the feeding area. These dead zones are where the aeration heads cannot deliver gas, making it difficult for seeds in these areas to burst open. Seeds tend to accumulate in these areas, and the roots of germinated seeds become tangled, easily clogging the discharge flange pipe and causing feeding difficulties.

[0023] To address the aforementioned shortcomings, two of the most effective methods are: first, lowering the position of the aeration heads, or even placing them directly inside the discharge flange pipe, to reduce the aeration dead zone. However, this method significantly reduces the discharge space at the outlet, easily leading to blockage. Second, using a water-assisted discharge method, forcibly discharging the material using water pressure. However, existing germination devices typically have a metering discharge mechanism below the outlet, making this method impractical. The objective of this embodiment is to provide an aeration device that effectively reduces the aeration dead zone, ensures normal material feeding, and is suitable for metered material feeding.

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] like Figure 1 , Figure 2 As shown, this embodiment of an aeration device for a vertical germination tank includes a germination tank body 100 and an aeration mechanism 200. The germination tank body 100 is used for soaking and germinating seeds; the aeration mechanism 200 is used for aeration within the germination tank body 100. Of course, a water supply mechanism is also required for supplying water to the germination tank body 100. The water supply mechanism can employ existing technology and is not specifically limited here.

[0026] 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, which is connected to a discharge valve 150 through a flange pipe 140.

[0027] In some alternative embodiments, a sleeve 130 is fitted onto the lower part of the cone 120, and several through holes 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 transition space. Simultaneously, an outlet is formed at the bottom of the sleeve 130.

[0028] The aeration mechanism 200 includes several aeration heads 210 arranged in a ring within the transition space. Each aeration head 210 is connected to an aeration pipe 220. The free end of the aeration pipe 220 passes through the sleeve 130 and is connected to an aeration blower (not shown in the figure).

[0029] This embodiment provides an aeration device for a vertical germination tank. During the initial soaking stage, the seeds require a large amount of water. At this time, water can be injected into the sleeve 130 and then enter the germination tank body 100 through the through-hole to soak and absorb water from the seeds. During the aeration process, the air bubbles generated by the aeration head 210 can enter the germination tank body 100 through the through-hole.

[0030] During the later stages of germination, excess water in the germination tank 100 can flow back into the sleeve 130 through the through-hole, and then be discharged through the outlet at the bottom of the sleeve 130. This prevents the seeds from becoming oxygen-deficient due to continuous soaking, which can inhibit respiration and metabolism, and even cause seed rot. Simultaneously, the seeds can be sprayed periodically during the germination process to maintain environmental humidity and accelerate germination.

[0031] As can be seen from the above soaking process, in this embodiment, the through holes on the cone 120 are used for both water filtration and aeration. At the same time, the size of these through holes needs to be smaller than the size of the seeds to prevent seeds inside the germination tank body 100 from entering the transition space.

[0032] In some embodiments, the through-hole is an elongated or oblong hole, and the width of the through-hole does not exceed 3 mm. On the one hand, it can effectively block the seeds from passing through the through-hole; on the other hand, it can ensure better water filtration and aeration effects.

[0033] Furthermore, the dimensions of the through-hole are 1.8-2.2mm*16-24mm. For example, 1.8mm*24mm, 2.0mm*22mm, 2.2mm*16mm, etc.

[0034] In this specific implementation, the through hole is 2.0mm*20mm in size; three aeration heads 210 are provided in a ring, and a control valve 230 is installed in the area outside the transition space of the aeration pipe 220.

[0035] This embodiment provides an aeration device for a vertical germination tank. An aeration head 210 is positioned within the transition space and aerates the germination tank body 100 through a through-hole on the cone 120. This design ensures that the aeration head 210 does not obstruct the feed inlet, allowing it to be positioned closer to the bottom of the germination tank body 100. This effectively reduces aeration dead zones in the bottom area and ensures smooth feed flow later.

[0036] In some alternative embodiments, a vibration source 300 is provided at the bottom of the sleeve 130. Specifically, a mounting plate is provided at the bottom of the sleeve 130, and the vibration source 300 is mounted on the mounting plate.

[0037] Preferably, the vibration source 300 can be a vibration motor, which can provide excitation force in the vertical direction. During feeding, the vibration motor vibrates, causing the barrel wall to vibrate, which promotes the feeding of seeds in the flange pipe 140 and also prevents the accumulation of seeds.

[0038] like Figure 4 As shown, in some alternative embodiments, the flange pipe 140 is provided with a plurality of air blowing holes 141 arranged in a ring. The air blowing holes 141 are connected to an air pump (not shown in the figure) through a pipe, and the air pump is located above the air blowing holes 141.

[0039] Specifically in this embodiment, the air inlet pipe of the air blowing hole 141 extends from the outside of the germination tank body to the highest point of the germination tank before connecting to the air pump. A solenoid valve is installed on the air inlet pipe, which is located at the highest point of the air inlet pipe. The air inlet pipe runs upward to prevent water from flowing back into the solenoid valve and the air pump.

[0040] During feeding, air is blown into the flange tube 140 through the air blowing hole 141. The airflow disturbs the seeds accumulated in the flange tube 140. In addition, the aeration head 210 disturbs the seeds above the flange tube 140, which can further ensure the smoothness of feeding and effectively avoid the situation where seeds accumulate and cannot be discharged.

[0041] refer to Figure 1 As shown, as a further improvement to the aeration device for a vertical germination tank in this embodiment, based on the above embodiment, a support mechanism 400 for supporting the germination tank body 100 is also included.

[0042] Specifically, refer to Figure 5 , Figure 6 , Figure 7 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.

[0043] 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. Meanwhile, both the support columns 410 and the conduits 420 are provided with wire-passing holes 421 to facilitate wire threading.

[0044] 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.

[0045] 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.
