Description

Technical Field

[0001] This utility model belongs to the field of seedling tray technology, specifically a seedling tray that is easy to ventilate. Background Technology

[0002] A seedling tray is a standardized container used in agriculture and horticulture. It is usually made of materials such as plastic and has multiple independent seedling holes or cavities inside. It is mainly used for centralized cultivation of seedlings of vegetables, flowers, seedlings and other crops. It can provide a stable environment for seed germination and seedling growth, while facilitating unified management and transplanting, reducing damage to seedling roots, and improving seedling efficiency and survival rate.

[0003] The existing utility model with authorization announcement number CN219088054U discloses a seedling tray. When connecting multiple seedling boards, firstly, the pull ring and the baffle are moved closer to each other. Since the baffle is limited by the seedling board, only the pull ring moves, which facilitates the movement of the insertion shaft. The pull ring drives the insertion shaft to slide from the surface of the mounting plate. At this time, the spring is in the open state. Then, the two seedling boards are moved closer to each other. The limiting arm is inserted into the limiting frame by the movement of the seedling board. Then, the pull ring is released. At this time, the spring is in the contracted state, which drives the insertion shaft to insert from the surface of the fixing plate into the inner wall of the positioning hole on one side of the limiting arm. The spring plays an auxiliary role in fixing the insertion shaft. At this time, the connection between the two seedling boards is completed. The seedling boards are assembled using an assembly unit, thereby reducing the phenomenon of seedling boards being submerged in water and causing seedlings to drown due to mutual compression between the seedling boards.

[0004] While the above technical solution allows for the assembly of seedling trays using assembly units, thus reducing the risk of seedlings drowning due to some trays being submerged in water caused by mutual compression, it also makes it inconvenient to adjust the height of the seedling trays. The lack of a height adjustment structure means that when different seedling trays are placed horizontally together, lower seedlings are easily blocked by higher seedlings, leading to poor ventilation and potentially affecting the healthy development of the seedlings.

[0005] Therefore, it is necessary to design a device that allows for easy adjustment of the height of the seedling tray, thereby facilitating ventilation between plants. Utility Model Content

[0006] To address the above technical problems, this utility model provides a device that facilitates the adjustment of the height of the seedling tray, thereby improving ventilation between plants. This solves the problem that existing devices cannot adjust the height of the seedling tray, leading to easy mutual interference and poor ventilation among plants.

[0007] To solve the above technical problems, the technical solution of this utility model is as follows: a seedling tray with easy ventilation, including a multi-slot tray, a lifting frame is snapped onto the outer surface of the multi-slot tray, two base plates are provided below the lifting frame, and a guide plate and a limiting guide rod are fixedly connected to the upper surface of each base plate. The guide plate and the limiting guide rod are slidably connected to the inside of the lifting frame. Several identical limiting holes are opened on the outer surface of each guide plate. Two limiting pins are snapped into the inside of both sides of the lifting frame. Two first magnetic blocks are fixedly connected to the inner wall of the lifting frame. A second magnetic block is fixedly connected to the end of each of the two limiting pins that are close to each other. Each limiting pin passes through the side wall of the lifting frame and is inserted into the limiting hole. Each second magnetic block is in contact with the first magnetic block.

[0008] Furthermore, each of the two base plates has an assembly plate fixedly connected to one of its opposite sides, and each assembly plate has several identical assembly holes on its upper surface.

[0009] Furthermore, two limiting plates are fixedly connected to one side of each of the two base plates that are close to each other, and a limiting cone is slidably connected inside each of the limiting plates.

[0010] Furthermore, each of the limiting cones and limiting pins has an anti-slip sleeve fixedly connected to its outer surface, and each of the anti-slip sleeves has several identical anti-slip protrusions fixedly connected to its outer surface.

[0011] Furthermore, the limiting guide rods are respectively arranged parallel to each other on both sides of the guide plate.

[0012] Furthermore, handle supports are fixedly connected to both the front and rear sides of the lifting frame, and a handle is rotatably connected to each handle support.

[0013] This utility model has the following advantages compared with the prior art:

[0014] This invention utilizes a multi-slot tray and a lifting frame that interlock, along with a guide plate fixed to the base plate. By leveraging the contact between a limiting pin inside the lifting frame and a limiting hole on the outer surface of the guide plate, the height of the lifting frame and the multi-slot tray can be flexibly adjusted. Simultaneously, the contact between a first magnetic block on the inner wall of the lifting frame and a second magnetic block at the end of the limiting pin secures the pin within the limiting hole, preventing accidental sliding of the lifting frame after adjustment. This structure allows for adjustment of the multi-slot tray height according to actual seedling needs, effectively solving the problem of poor ventilation caused by lower seedlings being blocked by higher seedlings when different seedling trays are placed horizontally. It provides a good ventilation environment for seedling growth, promoting robust development. Furthermore, the overall structure is simple and easy to operate, adapting to various seedling scenarios and enhancing the flexibility and practicality of seedling tray use. It avoids the problem of poor ventilation caused by lower seedlings being blocked by higher seedlings when different seedling trays are placed horizontally, which can negatively impact seedling development.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 6The illustration shows a ventilated seedling tray, comprising a multi-slot tray 1. A lifting frame 2 is attached to the outer surface of the multi-slot tray 1. The lifting frame 2 is designed according to the specific shape of the multi-slot tray 1, precisely holding the tray in place. The lifting frame 2 has wider sides to facilitate the sliding connection between the guide plate 4 and the limiting guide rod 15. To increase stability and provide support, two base plates 3 are provided below the lifting frame 2. Each base plate 3 has a guide plate 4 and a limiting guide rod 15 fixedly connected to its upper surface. The guide plate 4 is a vertically arranged rectangular plate, and the limiting guide rod 15 is a vertically arranged cylindrical rod. All three are parallel and located on the same horizontal plane. The guide plate 4 and the limiting guide rod 15 are slidably connected to the interior of the lifting frame 2. Next, in order to facilitate the adjustment of the height of the multi-slot plate 1 and to facilitate its fixation, several identical limiting holes 5 are opened on the outer surface of each guide plate 4. The limiting holes 5 are evenly distributed and can facilitate the passage of the limiting pins 6. Two limiting pins 6 are snapped into the inside of both sides of the lifting frame 2. The limiting pins 6 are located in the middle of the left and right sides of the lifting frame 2. In order to fix the limiting pins 6, two first magnetic blocks 8 are fixedly connected to the inner wall of the lifting frame 2. A second magnetic block 7 is fixedly connected to the end of the two limiting pins 6 that are close to each other. Each limiting pin 6 passes through the side wall of the lifting frame 2 and is inserted into the limiting hole 5. Each second magnetic block 7 is in contact with the first magnetic block 8, and the first magnetic block 8 and the second magnetic block 7 are magnetically attracted to each other.

[0024] To facilitate interconnection with other seedling trays for mass cultivation, assembly plates 9 are fixedly connected to the two base plates 3 on opposite sides. Each assembly plate 9 has several identical assembly holes 10 on its upper surface.

[0025] To facilitate the connection of the seedling tray to the external support or the ground via bolts or other components, enhance the overall placement stability, and prevent the seedling tray from tipping over, two limiting plates 11 are fixedly connected to the sides of the two base plates 3 that are close to each other. Each limiting plate 11 has a limiting cone 12 slidably connected inside. When the seedling tray is placed on soft ground such as soil, the limiting cone 12 is inserted into the ground to further fix the position of the base plate 3, prevent the seedling tray from being pushed by external forces, and improve the stability of use on non-hard ground.

[0026] To facilitate operation and increase friction, anti-slip sleeves 13 are fixedly connected to the outer surfaces of each limiting cone 12 and limiting pin 6, and several identical anti-slip protrusions 14 are fixedly connected to the outer surfaces of each anti-slip sleeve 13.

[0027] In order to facilitate the limiting while ensuring the smooth up and down sliding of the lifting frame 2, the limiting guide rods 15 are respectively set parallel to both sides of the guide plate 4.

[0028] To facilitate the movement of the lifting frame 2, handle supports 16 are fixedly connected to both the front and rear sides of the lifting frame 2. Each handle support 16 is rotatably connected to a grip 17, and the entire device can be moved by gripping the grip 17.

[0029] The specific working process of this utility model is as follows:

[0030] When using, first select the fixing method according to the placement site. If placed on a hard ground, the base plate 3 can be fixed to the bracket or the ground with bolts through the mounting holes 10 on the mounting plate 9 to ensure the overall stability of the seedling tray. If placed on soft ground such as soil, the limiting cone 12 can be pushed to slide out from the limiting plate 11 and insert into the ground to further reinforce the base plate 3 and prevent displacement.

[0031] When adjusting the height of the multi-slot plate 1, first hold the anti-slip sleeve 13 outside the limit pin 6 and pull the limit pin 6 outward to separate the second magnetic block 7 from the first magnetic block 8. At this time, the limit pin 6 disengages from the limit hole 5 on the guide plate 4, and the lifting frame 2 is released from fixation. Then hold the handle 17 and move the lifting frame 2 up and down along the guide plate 4 and the limit guide rod 15. The multi-slot plate 1 moves synchronously with the lifting frame 2 until it is adjusted to a suitable height.

[0032] After the height is determined, the limiting pin 6 is released. Under the attraction of the first magnetic block 8 and the second magnetic block 7, the limiting pin 6 automatically inserts into the corresponding limiting hole 5, and the lifting frame 2 is re-fixed. At this time, the height of the multi-slot tray 1 is stable. When different seedling trays are placed horizontally, their respective heights can be adjusted to avoid the low-position seedlings being blocked, ensuring smooth ventilation and providing a good environment for seedling growth. When moving the seedling trays daily, the operator can hold the handle 17 and apply force with the help of the handle support 16 to easily move the seedling trays, improving the convenience of operation. The entire design of the seedling trays that facilitates ventilation effectively solves the problem that when different seedling trays are placed horizontally together, the low-position seedlings are easily blocked by the high-position seedlings, resulting in poor ventilation and thus affecting the vigorous development of the seedlings.
