Abstract
Description
Technical Field
[0001] This utility model relates to the field of medicinal herb seedling technology, specifically a medicinal herb seedling tray stacking and fixing device. Background Technology
[0002] In the field of medicinal herb seedling cultivation, the stacking and storage of seedling trays in large-scale production faces many challenges. Traditional stacking methods, due to the lack of effective fixing structures, are prone to problems such as tray tilting and tipping over, which not only damages the seedling roots and reduces the survival rate, but also limits space utilization and increases storage and transportation costs.
[0003] Vibrations from vehicle movement can cause unrestrained seedling trays to collide and crush each other. The bottom trays, bearing the weight of the upper trays and lacking top restraint, are prone to deformation. This compacts the soil, restricting root growth and causing stems and leaves to break or break, severely impacting seedling survival rates. Without top restraint, the number of stacking layers is typically reduced to avoid tipping, leading to underutilization of transport space, decreased transport volume, and significantly increased transport costs. Therefore, we propose a stacking and fixing device for medicinal herb seedling trays. Utility Model Content
[0004] The purpose of this utility model is to provide a stacking and fixing device for medicinal herb seedling trays to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a medicinal herb seedling tray stacking and fixing device, comprising a base, a seedling tray body disposed on the top of the base, and further comprising:
[0006] A fixing component, the fixing component including a column connected to the top of the base, a top frame connected to the top of the column, a pressure plate provided at the bottom of the top frame, and the pressure plate slidably connected to the column;
[0007] A limiting component includes a limiting ring slidably connected to a base, a connecting plate connected to the limiting ring, a lever rotatably connected to the connecting plate, a slot on the top of the top frame, a rotating shaft rotatably connected to the inner wall of the slot, and the lever rotatably connected to the rotating shaft.
[0008] Furthermore, four columns are provided, and four limiting rings are provided, with the four limiting rings slidably connected to the four columns respectively.
[0009] The above technical solution increases the stability of the pressure plate sliding by implementing the above settings.
[0010] Furthermore, a drive assembly is provided on the top of the top frame, the drive assembly includes a connecting seat, the connecting seat is connected to the lever, a screw is rotatably connected to the top of the top frame, the connecting seat is threaded onto the screw, and a rocker arm is connected to the top of the screw.
[0011] The above technical solution is adopted: by setting a driving component as the power source of the limiting component, the limiting ring is driven to slide on the column.
[0012] Furthermore, the base is provided with an auxiliary component, which includes a baffle. The upper and lower ends of the baffle are respectively connected to the base and the top frame, and the baffle is threadedly connected to the base and the top frame with bolts.
[0013] The above technical solution involves setting auxiliary components to limit the sides of the seedling tray to prevent lateral slippage.
[0014] Furthermore, a buffer assembly is provided on the column, the buffer assembly including a buffer pad, the buffer pad being slidably connected to the column, and the buffer pad being located between two adjacent seedling trays.
[0015] The above technical solution is adopted: by setting up a buffer component, the energy is absorbed through elastic deformation, the vibration amplitude is reduced, and the soil is prevented from loosening or the stems and leaves are broken due to the shaking of the seedling roots.
[0016] Furthermore, the top of the cushioning pad is provided with ventilation holes, and the bottom of the base is provided with casters.
[0017] The above technical solution is adopted to alleviate local temperature rise by setting vents and prevent the contact area between the bottom of the tray and the pad from being easily blocked by moisture evaporation, thus preventing the formation of a high-humidity environment.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, a fixing component is used to limit the top of the seedling trays, increasing the single-transport capacity. This limiting component allows adjustment of the pressure plate position based on the number of seedling trays transported each time, ensuring the pressure plate adheres closely to the surface of the top seedling tray. This solves the problem of un-limited seedling trays colliding and being crushed due to vibrations during vehicle travel. The bottom seedling trays, bearing the weight of the upper layers and lacking top restraint, are prone to deformation. The soil inside the trays becomes compacted, restricting the growth space for seedling roots. Stems and leaves may also break or be damaged due to compression, severely impacting seedling survival rates. Without top restraint, to avoid tipping, the number of stacked layers is usually reduced, leading to inefficient use of transport space, decreased single-transport capacity, and significantly increased transport costs.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] like Figures 1-5 As shown, this utility model provides a technical solution: a stacking and fixing device for medicinal herb seedling trays, including a base 1 and a seedling tray body 2 disposed on the top of the base 1, characterized in that it further includes:
[0035] The fixing component 3 includes a column 31 connected to the top of the base 1, a top frame 32 connected to the top of the column 31, and a pressure plate 33 provided at the bottom of the top frame 32. The pressure plate 33 is slidably connected to the column 31.
[0036] Limiting component 4 includes a limiting ring 41 slidably connected to the base 1, a connecting plate 42 connected to the limiting ring 41, a lever 43 rotatably connected to the connecting plate 42, a slot 44 opened on the top of the top frame 32, a rotating shaft 45 rotatably connected to the inner wall of the slot 44, and the lever 43 rotatably connected to the rotating shaft 45.
[0037] A drive assembly 5 is provided on the top of the top frame 32. The drive assembly 5 includes a connecting seat 51, which is connected to the lever 43. A screw 52 is rotatably connected to the top of the top frame 32. The connecting seat 51 is threadedly connected to the screw 52. A rocker arm 53 is connected to the top of the screw 52.
[0038] Specifically, the seedling tray is first placed on top of the base 1. Then, according to the height of the seedling tray, the rocker arm 53 is turned to drive the screw 52 to rotate on the top frame 32. The screw 52 drives the connecting seat 51 to move threadedly on the screw 52. The screw 52 drives the lever 43 to rotate through the rotating shaft 45. During the rotation, the lever 43 drives the connecting plate 42 to move. The connecting plate 42 drives the limiting rings 41 on both sides to slide on the column 31, so that the limiting rings 41 fit against the top of the pressure plate 33, limiting the pressure plate 33, thereby limiting the top of the seedling tray.
[0039] Furthermore, such as Figure 1 and Figure 4 As shown: There are four columns 31 and four limiting rings 41. The four limiting rings 41 are slidably connected to the four columns 31 respectively, which increases the stability of the sliding of the pressure plate 33.
[0040] The above solutions also include the need to limit the sides of the seedling tray to prevent lateral slippage, such as... Figure 2 As shown: An auxiliary component 6 is provided on the base 1. The auxiliary component 6 includes a baffle 61. The upper and lower ends of the baffle 61 are connected to the base 1 and the top frame 32 respectively. Bolts 62 are threadedly connected to the baffle 61, the base 1 and the top frame 32. By setting the baffle 61, the two sides of the seedling tray are limited to prevent side slippage.
[0041] The above solutions also require buffering between adjacent seedling trays to prevent collisions, such as... Figure 1 and Figure 3As shown: A buffer assembly 7 is provided on the column 31. The buffer assembly 7 includes a buffer pad 71, which is slidably connected to the column 31. The buffer pad 71 is located between two adjacent seedling tray bodies 2. A ventilation hole 72 is provided on the top of the buffer pad 71. A caster wheel 8 is provided at the bottom of the base 1. When bumps and vibrations occur during transportation, the buffer pad 71 can absorb part of the impact force generated by the vibration and protect the two adjacent seedling trays. The ventilation hole 72 allows the seedlings to pass through and prevents the seedlings from being squeezed.
[0042] The working principle provided by this utility model is as follows: Figures 1-5 As shown: First, the seedling tray is placed on top of the base 1. A buffer pad 71 is slidably installed between two adjacent seedling trays. When bumps and vibrations occur during transportation, the buffer pad 71 can absorb part of the impact force generated by the vibration, protecting the two adjacent seedling trays. The ventilation hole 72 allows the seedlings to pass through, preventing the seedlings from being squeezed. Then, according to the height of the seedling tray, the rocker arm 53 is turned to drive the screw 52 to rotate on the top frame 32. The screw 52 drives the connecting seat 51 to move threadedly on the screw 52. The screw 52 drives the lever 43 to rotate through the rotating shaft 45. During the rotation, the lever 43 will drive the connecting plate 42 to move. The connecting plate 42 drives the limiting rings 41 on both sides to slide on the column 31, so that the limiting rings 41 fit against the top of the pressure plate 33, limiting the pressure plate 33, thereby limiting the top of the seedling tray. Baffles 61 are set on both sides of the seedling tray to limit the two sides of the seedling tray and prevent side slippage.
