Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural seedling raising auxiliary equipment technical field especially, a kind of seedling tray moisture cover with adjustable air vent. BACKGROUND

[0002] In modern agricultural production, seedling raising is the key link to ensure crop yield and quality. The seedling raising process has strict requirements on the humidity, temperature and air flow of the environment. Therefore, seedling trays and matching moisture covers are widely used.

[0003] The main function of the moisture cover is to cover the seedling tray, forming a relatively closed space, effectively reducing the evaporation of internal moisture, keeping the substrate moist, and maintaining a stable temperature environment, which is crucial for seed germination and early growth of seedlings.

[0004] However, as the seedlings grow, their respiration increases, and their demand for fresh air also increases. If the traditional moisture cover is completely sealed, it will cause the internal air to be not ventilated, the humidity to be too high, and the bacteria to be easy to breed, resulting in the seedlings to be overgrown or to have diseases.

[0005] To solve this problem, some existing moisture covers are designed with fixed ventilation holes. Although this design achieves a certain degree of air exchange, the ventilation volume is fixed. When the seedlings just germinate, the fixed ventilation holes may cause the moisture to be lost too quickly; while when the seedlings grow up and need a lot of air exchange, the fixed ventilation holes may not be enough.

[0006] This fixed ventilation design cannot dynamically adapt to the different needs of humidity and ventilation volume at different growth stages of seedlings (such as germination period, cotyledon period, and true leaf period). Users must manually adjust by frequently uncovering or removing the cover, which is not only cumbersome to operate, but also easy to cause the seedling environment to fluctuate sharply, which is not conducive to the healthy growth of seedlings.

[0007] Therefore, the utility model provides a seedling tray moisture cover with adjustable air vent to solve the problems of the prior art. CONTENT OF THE UTILITY MODEL

[0008] In view of the fact that the size of the ventilation hole of the seedling tray moisture cover in the prior art is fixed and cannot be flexibly adjusted according to the growth stage of the seedlings or the environmental humidity, resulting in the problem that the moisture retention effect and the ventilation effect are difficult to balance, the utility model aims to provide a seedling tray moisture cover with adjustable air vent with improved structure, which can effectively solve the above problems.

[0009] The utility model provides a seedling tray moisture cover with adjustable air vent, which comprises a bottom tray, a cover plate covering the bottom tray, a moisture retention mechanism and an adjusting mechanism arranged on the upper surface of the cover plate.

[0010] The moisturizing mechanism comprises a fixed plate, a supporting rod and a conical cover, and the adjusting mechanism comprises a knob, a clasp and a threaded rod.

[0011] The fixed plate is fixedly connected to the inner wall of the hole, the supporting rod is fixedly connected to the center of the fixed plate, the threaded rod is threadedly connected to the inside of the supporting rod, the knob is fixedly connected to one end of the threaded rod, the clasp is fixedly connected below the knob, and the conical cover is arranged between the knob and the clasp.

[0012] Preferably, the conical cover adopts an inverted conical structure.

[0013] Preferably, the inside of the bottom disc is provided with a storage groove.

[0014] Preferably, the cover plate is provided with a handle.

[0015] Preferably, the handle is fixedly connected to the outer wall of the cover plate.

[0016] Preferably, the supporting rod is a hollow structure, and the inner wall of the supporting rod is provided with an internal thread for threadedly connecting with the threaded rod.

[0017] Preferably, the middle part of the conical cover is provided with a through hole, and the threaded rod is arranged in the through hole.

[0018] Preferably, the conical cover is clamped between the bottom surface of the knob and the top surface of the clasp.

[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Embodiment: please refer to Figures 1 to 4 The utility model embodiment provides a seedling tray moisture cover with adjustable ventilation opening, which aims at solving the problem that the size of the ventilation opening of the seedling tray moisture cover is fixed in the prior art, and the ventilation opening cannot be flexibly adjusted according to the growth stage of seedlings or environmental humidity, resulting in that the moisture retaining and ventilation effects are difficult to be considered.

[0025] As Figure 1 and Figure 2 shown, the seedling tray moisture cover with adjustable ventilation opening comprises a bottom disc 1 and a cover plate 2 covering above the bottom disc 1, the inside of the bottom disc 1 is provided with a storage groove 6, the cover plate 2 is provided with a handle 3, referring to Figure 4 The handle 3 is fixedly connected to the outer wall of the cover plate 2.

[0026] As Figure 1 shown, the upper surface of the cover plate 2 is provided with a moisture retaining mechanism 4 and an adjusting mechanism 5, the moisture retaining mechanism 4 comprises a fixed plate 402, a support rod 403 and a conical cover 401, a hole is formed above the cover plate 2, the fixed plate 402 is fixedly connected to the inner wall of the hole, the support rod 403 is fixedly connected above the center of the fixed plate 402, the support rod 403 is a hollow structure, the inner wall of the support rod 403 is provided with internal threads for threadedly connecting with a threaded rod 503, and the conical cover 401 adopts an inverted conical structure.

[0027] Reference Figure 1 and Figure 3 The adjusting mechanism 5 includes a knob 501, a retaining ring 502, and a threaded rod 503. The threaded rod 503 is threadedly connected to the inside of the support rod 403. The knob 501 is fixedly connected to one end of the threaded rod 503. The retaining ring 502 is fixedly connected to the bottom of the knob 501. A conical cover 401 is disposed between the knob 501 and the retaining ring 502. Specifically, a through hole is provided in the middle of the conical cover 401, the threaded rod 503 passes through the through hole, and the conical cover 401 is clamped between the bottom surface of the knob 501 and the top surface of the retaining ring 502.

[0028] Please refer to the following carefully. Figure 3 The core working structure and operation of the adjustment mechanism 5 and the humidification mechanism 4 are described in detail below: The support rod 403 has a hollow structure with internal threads on its inner wall. The threaded rod 503 is threaded into the support rod 403. The knob 501 is fixedly connected to the end of the threaded rod 503 away from the cover plate 2. The retaining ring 502 is fixedly connected to the bottom of the knob 501. A through hole is provided in the middle of the conical cover 401, and the threaded rod 503 passes through the through hole. The conical cover 401 is clamped between the bottom surface of the knob 501 and the top surface of the retaining ring 502, so that the conical cover 401, the knob 501, the retaining ring 502 and the threaded rod 503 form a moving whole. When adjusting the air vent, the user turns knob 501, which drives threaded rod 503 to rotate together via a fixed connection. Because the threaded rod 503 is threadedly connected to the fixed support rod 403 on the fixed plate 402, the threaded rod 503 will move linearly along the axial direction of the support rod 403 when it rotates, that is, it will rise or fall. This threaded drive mechanism causes the clamped conical cover 401 to rise or fall synchronously, thereby changing the gap between the bottom edge of the conical cover 401 and the upper surface of the cover plate 2, ensuring that the size of the vent can be precisely adjusted.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, the chassis 1 has multiple storage slots 6 inside, which are used to place and cultivate seedlings to realize the basic function of the seedling tray.

[0030] As another preferred embodiment, a handle 3 is provided on the outer edge of the cover plate 2. The handle 3 is fixedly connected to the outer wall of the cover plate 2, which makes it convenient for users to pick up and place the cover plate 2 and improves the ease of operation.

[0031] As another preferred embodiment, the conical cover 401 in the humidification mechanism 4 adopts an inverted conical structure with the opening facing the inside of the cover plate 2. This structure allows water vapor inside the cover plate 2 to condense on the inner wall of the conical cover 401 and then flow back to the chassis 1 along the inverted conical surface, effectively locking in the internal moisture and reducing moisture loss.

[0032] As another preferred embodiment, the support rod 403 has a hollow structure with an internal thread on its inner wall. This internal thread matches the external thread of the threaded rod 503, ensuring the precise lifting and lowering movement of the threaded rod 503 during rotation and achieving the stability of the ventilation opening adjustment.

[0033] As another preferred embodiment, the conical cover 401 has a through hole in the middle, and the threaded rod 503 passes through the through hole. The conical cover 401 is clamped between the bottom surface of the knob 501 and the top surface of the retaining ring 502. This clamping and fixed connection method ensures that the conical cover 401 can reliably rise and fall synchronously with the threaded rod 503, avoiding the problems of relative movement and adjustment failure.

[0034] Working principle: When it is necessary to adjust the ventilation in the seedling tray, the user turns the knob 501 of the adjustment mechanism 5. The knob 501 is fixedly connected to the threaded rod 503, which drives the threaded rod 503 to rotate together. Since the threaded rod 503 is threadedly connected to the fixed support rod 403 in the moisture retention mechanism 4, there is a precise thread transmission fit between the threaded rod 503 and the internal thread of the support rod 403. The rotational motion of the threaded rod 503 is converted into a linear lifting motion along the axis of the support rod 403.

[0035] Because the conical cover 401 has a through hole in the middle and is clamped between the bottom surface of the knob 501 and the top surface of the retaining ring 502, the conical cover 401 rises or falls synchronously with the threaded rod 503. This lifting and lowering movement changes the size of the gap between the bottom edge of the conical cover 401 and the upper surface of the cover plate 2, thereby realizing the precise adjustment of the vent. Through this synergistic effect of the moisturizing mechanism 4 and the adjusting mechanism 5, this utility model solves the problem of the fixed size of the vent and the inability to adjust it flexibly in the prior art.

[0036] Meanwhile, the conical cover 401 in the humidification mechanism 4 adopts an inverted conical structure. After the water vapor evaporated inside the cover plate 2 condenses on the inner wall of the conical cover 401, it can flow back to the chassis 1 along its inner wall, effectively locking in moisture and achieving the unity of humidification and adjustable ventilation.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
