Description

Technical Field

[0001] This utility model belongs to the field of seedling tray technology, and specifically relates to a pollution-free nutrient seedling tray. Background Technology

[0002] In modern agricultural production, the seedling raising stage of crops such as rice plays a decisive role in the final yield and quality. Nutrient seedling trays, as a key tool in the seedling raising process, are widely used because they can provide a suitable growth environment for seedlings and seeds and enable large-scale seedling raising. Soaking seedlings is one of the commonly used methods in rice seedling raising.

[0003] To optimize the use and storage of seedling trays, many innovative designs have emerged. For example, the seedling tray disclosed in Chinese Patent No. CN210537697U consists of a rectangular ring-shaped support plate, a tray formed by recesses into the support plate, and a first partition fixed at one end of the tray. Through a unique structural design, the tray is divided into different parts, and the bottom plate of the tray is provided with diamond-shaped stripes and ventilation holes, which meets the seedling raising function requirements of the seedling tray. In terms of storage, the seedling tray adopts a stacking design. When empty trays are stacked, space can be saved by a specific alignment method. When seedling trays are stacked, another alignment method can reserve enough space for seedling growth.

[0004] However, after in-depth practical application, it was found that the stacking design of the seedling tray has significant defects. It lacks a stable limiting structure during application. When the seedling trays are stacked, there are no fixed joints between them. Relying solely on the simple stacking method, the overall stability is poor. In actual agricultural production scenarios, the operating environment is complex. The seedling trays are often placed outdoors or in greenhouses, and are easily affected by factors such as people walking and wind. Once the seedling trays are accidentally touched, they are very easy to tip over and collapse. The seedlings, seeds, and substrate in the trays will spill out, which will not only damage the seedlings and seeds and affect the seedling effect, but also lead to the waste of manpower, material resources and time. This seriously restricts its promotion and application in agricultural production. Therefore, it is urgent to improve the stacking structure of the seedling trays to enhance their stability and practicality. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a pollution-free nutrient seedling tray to solve the problem that the existing technology lacks stable positioning of stacked seedling trays and has poor overall stability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A pollution-free nutrient seedling tray includes several trays. Each tray has a splicing mechanism fixedly installed on both sides and spliced ​​together with each other through the splicing mechanism. Each tray has a mesh tray mechanism placed on its top.

[0008] The splicing mechanism includes side rails and limiting components. The side rails are fixedly installed on both sides of the pallet. A slider is slidably connected inside the side rails. A connecting arm is fixedly installed on the outside of the slider. The top of the connecting arm is connected to the bottom of the pallet. The limiting component is fixedly installed in the middle of one side of the pallet. The top of the limiting component is engaged with the bottom of the pallet.

[0009] As a preferred technical solution, the mesh tray mechanism includes a filter mesh tray, which is placed inside the tray. Fixing blocks are fixedly installed on both sides of the top of the filter mesh tray, and bridge-type handrails are fixedly installed on the top of the fixing blocks.

[0010] As a preferred technical solution, the side shapes of the filter screen and the tray are both set as isosceles trapezoids, and the outer surface of the bridge-type handrail is fixedly connected with an anti-slip handrail glove.

[0011] As a preferred technical solution, the internal cross-sectional shape of the side rail is set to a convex shape, and the side shape of the slider is also set to a convex shape.

[0012] As a preferred technical solution, the limiting component includes a fixing frame and a slot. The fixing frame is fixedly installed on the middle of one side of the tray. A limiting spring is fixedly connected inside the fixing frame. A movable block is fixedly installed on the top of the limiting spring. A locking block is fixedly installed on the top of the movable block. The slot is opened on the bottom of the tray near the fixing frame. The end of the locking block passes through the fixing frame and is inserted into the inside of the slot.

[0013] As a preferred technical solution, an adjusting push plate is fixedly installed on the outer side of the movable block, and the tray adjusting push plate is circular.

[0014] As a preferred technical solution, the outer corners of the tray, side rail and filter screen are all set to be arc-shaped, and the internal top view shape of the movable block and the internal top view shape of the fixed frame are both set to be convex.

[0015] In summary, the present invention has the following main advantages:

[0016] Firstly, this device features a splicing mechanism that allows the slider to be inserted into the side rail to stably stack the trays during use. If the side of the tray is accidentally hit, the connecting arm, through the limiting action of the slider and the side rail, prevents the tray from shifting and falling off, providing excellent protection. During seedling cultivation, seedlings and seeds are placed in the filter screen, and the liquid medicine is poured into the tray. When removing the seeds, the person holds the bridge-type handle and pulls the fixing block to remove the filter screen from the tray. There is no need to use a filter bag, making it quick and convenient. This greatly improves the ease of use of the device and enhances the efficiency of seedling cultivation.

[0017] Secondly, by setting a limiting component, this device can further enhance the stability of tray stacking. During use, after the slider and side rail are installed, press the adjusting push plate to move the movable block down and squeeze the limiting spring, which in turn moves the locking block down, making it easy for the slider to be fully inserted into the side rail. After the trays are stacked and aligned, release the adjusting push plate, and the limiting spring will reset and push the movable block to allow the locking block to engage with the slot. In this way, when the sides of the tray are impacted, the slider and side rail are limited; when the front and rear are impacted, the locking block and slot are limited, realizing the quick and stable limiting installation of the trays. This device can stably stack multiple trays, which is convenient for large-scale seedling cultivation. Attached Figure Description

[0024] Example

[0025] refer to Figures 1 to 5The pollution-free nutrient seedling tray described in this embodiment includes a tray 1, wherein several trays 1 are configured, and a splicing mechanism 2 is fixedly installed on both sides of each tray 1 and movably installed on the outer side. The trays 1 are spliced ​​together with each other through the splicing mechanism 2, and a net tray mechanism 3 is placed on the top of each tray 1.

[0026] The splicing mechanism 2 includes side rails 21 and limiting components 22. The side rails 21 are fixedly installed on both sides of the tray 1. A slider 23 is slidably connected inside the side rails 21. A connecting arm 24 is fixedly installed on the outside of the slider 23. The top of the connecting arm 24 is connected to the bottom of the tray 1. The limiting component 22 is fixedly installed in the middle of one side of the tray 1. The top of the limiting component 22 is engaged with the bottom of the tray 1. In the design of this pollution-free nutrient seedling tray, the splicing mechanism 2 is the key to achieving the connection and stability of the trays 1. The side rails 21 fixedly installed on both sides of the tray 1 provide sliding tracks for the slider 23. When it is necessary to splice the trays 1, the slider 23 of one tray 1 is moved along the other tray. When the side rail 21 is inserted, the connecting arm 24 comes into play, with its top connected to the bottom of the tray 1, ensuring that the two trays 1 maintain a stable relative position during the splicing process. The limiting component 22 further ensures the reliability of the splicing. The limiting component 22 is fixed to the middle of one side of the tray 1, and its top is engaged with the bottom of the tray 1. When the slider 23 is fully slid into the predetermined position of the side rail 21, the limiting component 22 is activated, limiting the tray 1 by engaging to prevent the slider 23 from accidentally sliding out of the side rail 21. This ensures that multiple trays 1 are stably spliced ​​together by the splicing mechanism 2, providing support for the overall structural stability of the seedling trays. It also facilitates the flexible combination of the number and layout of trays 1 according to needs in actual seedling raising scenarios.

[0027] refer to Figures 1-4The mesh tray mechanism 3 includes a filter mesh tray 31, which is placed inside the tray 1. Fixing blocks 32 are fixedly installed on both sides of the top of the filter mesh tray 31. A bridge-type handrail 33 is fixedly installed on the top of each fixing block 32. The side shapes of both the filter mesh tray 31 and the tray 1 are isosceles trapezoids. Anti-slip handrails are fixedly connected to the outer surface of the bridge-type handrail 33. The internal cross-sectional shape of the side rail 21 is convex, and the side shape of the slider 23 is also convex. In this pollution-free nutrient seedling tray mesh tray mechanism 3 design, the filter mesh tray 31, as the core component, undertakes the important tasks of cultivating seedlings and working in conjunction with the tray 1. The filter mesh tray 31 is placed inside the tray 1, and the fixing blocks 32 on both sides of its top are connected to the bridge-type handrail 33, providing convenient gripping points for the operator. When it is necessary to operate on the seedlings in the seedling tray, such as removing the seedlings or changing the solution, the operator can hold the non-slip handgrip on the bridge handle 33 and use the connection between the bridge handle 33 and the fixing block 32 to easily and stably lift the filter screen 31. Since the side shape of the screen and the tray 1 is an isosceles trapezoid, this special design is conducive to the stacking of the trays 1 and the placement and removal of the filter screen 31 in the tray 1. It can better utilize the space and prevent the filter screen 31 from shaking in the tray 1. In addition, the side rail 21 and the slider 23 adopt a convex cross section and side shape. This unique design ensures that the slider 23 can slide smoothly in the side rail 21, while effectively preventing the slider 23 from falling out of the side rail 21, ensuring the stability of the connection of the tray 1 in the splicing mechanism 2, and thus ensuring the normal operation of the entire seedling tray system.

[0028] refer to Figures 4-5The limiting component 22 includes a fixing frame 221 and a slot 222. The fixing frame 221 is fixedly installed on the middle of one side of the tray 1. A limiting spring 223 is fixedly connected inside the fixing frame 221. A movable block 224 is fixedly installed on the top of the limiting spring 223. A locking block 225 is fixedly installed on the top of the movable block 224. The slot 222 is opened on the bottom of the tray 1 near the fixing frame 221. The end of the locking block 225 passes through the fixing frame 221 and is inserted into the inner side of the slot 222. The outer side of the movable block 224... An adjusting push plate 226 is fixedly installed on the tray 1. The adjusting push plate 226 is circular. The outer corners of the tray 1, side rail 21, and filter screen 31 are all rounded. The internal top view shape of the movable block 224 and the internal top view shape of the fixed frame 221 are both convex. In the limiting component 22 of this pollution-free nutrient seedling tray, the fixed frame 221 serves as a basic support structure and is stably installed in the middle of one side of the tray 1. The limiting spring 223 inside is connected to the movable block 224. When it is necessary to perform splicing operation on the tray 1, it is pushed... The circular adjusting push plate 226 on the outer side of the movable block 224 causes the movable block 224 to move downwards against the force of the limiting spring 223, which in turn causes the top locking block 225 to descend synchronously, disengaging the locking block 225 from the slot 222. At this point, the slider 23 can slide along the side rail 21 to achieve the splicing of the trays 1. When the slider 23 reaches the predetermined position and the trays 1 are spliced, the adjusting push plate 226 is released. Due to the elastic recovery of the limiting spring 223, the upward deformation force pushes the movable block 224 upwards, thereby causing the locking block 225 to re-insert into the slot 222. The tray 1 is firmly positioned to prevent it from shifting or separating due to shaking or external force during use after being assembled. The outer corners of the tray 1, side rail 21, and filter screen 31 are designed with rounded edges to avoid injury to personnel during operation and reduce collision damage. The movable block 224 and the fixed frame 221 are both convex in shape when viewed from above, which ensures that the movable block 224 slides stably within the fixed frame 221 and prevents it from shifting during up and down movement. This ensures the reliable operation of the limiting component 22 and further improves the stability of the tray 1 during application.

[0029] Operating principle and advantages: This device innovatively sets up a splicing mechanism 2, which significantly improves the ease of use and stability of the seedling tray. In practical applications, the slider 23 is precisely inserted into the side rail 21, which can realize the stable stacking of the tray 1. When it encounters an accidental impact or touches the side of the tray 1, the connecting arm 24 effectively prevents the tray 1 from being misaligned or falling off due to the mutual limiting effect of the slider 23 and the side rail 21, thus providing reliable protection for the seedling tray.

[0030] During the seedling raising process, seedlings are placed in the filter screen 31, and then a solution is added to the tray 1 for soaking. When it is necessary to remove the seedlings, the operator only needs to hold the bridge handle 33 and pull the fixing block 32. The fixing block 32 will move the filter screen 31 upward, allowing the filter screen 31 to detach smoothly from the tray 1. This design eliminates the cumbersome traditional method of using a filter net to pick up and put down seedlings, greatly improving the efficiency of picking up and putting down, ensuring that all seedlings can be quickly picked up, and further enhancing the convenience of the device during use, providing strong support for the efficient development of seedling raising work.

[0031] The limiting component 22 equipped in this device further optimizes the performance of the seedling trays. After the slider 23 and the side rail 21 are slidably installed, the adjusting push plate 226 on the movable block 224 is adjusted. The force applied by the adjusting push plate 226 causes the movable block 224 to move downward, thereby squeezing the limiting spring 223 and causing it to contract. At the same time as the limiting spring 223 contracts, the movable block 224 simultaneously drives the locking block 225 to move downward, so that the slider 23 can be fully inserted into the side rail 21. When the trays 1 are stacked and aligned as required, simply release the adjusting push plate 226. At this time, the limiting spring 223 quickly returns to its original position, pushing the movable block 224 upward. The movable block 224 drives the locking block. The 225 is precisely inserted into the slot 222. Through the tight engagement and limiting of the 225 and the slot 222, the tray 1 can be quickly and stably fixed. When the tray 1 is impacted from both sides, the slider 23 and the side rail 21 play a limiting role. When it is impacted from the front and back, the 225 and the slot 222 limit each other, effectively ensuring the stability of the tray 1. With the synergistic effect of the splicing mechanism 2 and the limiting component 22, this device can stably stack multiple trays 1. While realizing the rapid assembly and disassembly of the trays 1, it ensures that the overall structure has strong stability, which is highly adaptable to the needs of large-scale seedling raising operations and provides a solid guarantee for the large-scale development of agricultural production.
