Description

Technical Field

[0001] This utility model relates to the field of fresh-keeping transport boxes, and in particular to a fresh-keeping transport box for Angelica sinensis seedlings. Background Technology

[0002] As an important traditional Chinese medicinal herb, the cultivation industry of Angelica sinensis is developing rapidly. In the cultivation process, a model of off-site seedling cultivation and local transplanting is often adopted. Therefore, the healthy transportation of seedlings is a crucial link in ensuring the yield and quality of Angelica sinensis. To ensure the survival rate and freshness of seedlings during transportation, the industry generally uses specialized transport boxes with moisturizing and irrigation functions. Traditional refrigerated transport boxes usually have atomizing spray equipment inside the box, which intermittently sprays water mist to replenish moisture to the multi-layered stacked seedlings.

[0003] However, to increase the volume of seedlings transported at one time, seedlings are often stacked in multiple layers within the container. The water flow from the top-down sprinkler system is largely intercepted and absorbed by the seedlings and their pots on the upper layers, resulting in insufficient water reaching the seedlings in the lower layers. This directly causes uneven humidity distribution within the container. Seedlings in the upper layers may suffer from root rot or disease due to overwatering, while those in the lower layers will dry out and wilt due to lack of water, making it difficult to guarantee the overall survival rate. The root cause of this problem is that the water flow path of traditional top-sprinkler systems is fixed and uncontrollable, failing to provide precise and on-demand water supply based on the actual conditions of each layer and each seedling unit, leading to indiscriminate irrigation and resource waste. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the top spraying method of traditional transport boxes cannot accurately and on demand supply water according to the actual situation of each layer and each seedling unit, resulting in blind irrigation and waste of resources. Therefore, this invention proposes a fresh transport box for Angelica seedlings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fresh transport box for Angelica seedlings includes a box body and at least one carrying unit disposed inside the box body. The carrying unit is provided with a support rod at its bottom for longitudinal stacking inside the box body to form a multi-layer carrying space. The carrying unit is provided with multiple placement openings for accommodating seedling pots. The transport container also includes a drip irrigation system; The drip irrigation system includes a liquid storage tank located outside the box body, and a water distribution pipe located below each layer of the supporting unit; Each of the water distribution pipes is connected to a drip irrigation pipe at each of the placement ports; A clamping mechanism is provided on the side of the placement port. The clamping mechanism includes a rotatable rotating block and an elastic element that drives the rotating block to reset. The water outlet end of the drip irrigation tube is located near the placement port and is controlled by a flow-cutting component provided on the clamping mechanism. When no seedling pot is placed in the placement port, the rotating block is in the first position under the action of the elastic element, and the drip irrigation pipe is pressed by the flow-cutting component to cut off the flow. When the seedling pot is placed in the placement port, the seedling pot drives the rotating block to rotate to the second position, the flow interruption component releases the pressure on the drip irrigation pipe, and the drip irrigation pipe is connected.

[0006] Preferably, the clamping mechanism further includes: A positioning part located on the upper part of the rotating block and bent towards the inside of the placement opening is used to hold the upper edge of the seedling pot in the second position; A clamping part located at the lower part of the rotating block and converging towards the inside of the placement opening is used to contact and be squeezed with the outside of the pot when the seedling pot is placed, thereby causing the rotating block to rotate.

[0007] Preferably, both the positioning part and the clamping part are elastic metal sheets.

[0008] Preferably, the drip irrigation tube is a flexible tube, and the water outlet end of the drip irrigation tube is guided from below and fixed on the positioning part, and extends toward the center of the placement port.

[0009] Preferably, the water distribution pipe is provided with a vertical connecting pipe, the connecting pipe including a main connector and a secondary connector, and the bottom of the tank is also provided with a main connector that communicates with the liquid storage tank; When multiple layers of the aforementioned bearing units are stacked, the secondary connector of the upper bearing unit is sealed and connected with the adjacent primary connector below it, and the secondary connector of the uppermost bearing unit is sealed by a plug.

[0010] Preferably, the drip irrigation system is configured in two groups, each connected to a different storage tank, for drip irrigation of water and nutrient solution respectively.

[0011] Preferably, the side wall of the box is provided with a vent.

[0012] Preferably, a support frame adapted to the contour of the seedling pot is connected below the placement opening.

[0013] This utility model has the following advantages compared with the prior art: 1. It realizes precise and on-demand automated drip irrigation, and completely solves the problem of uneven irrigation under multi-layer stacking; This application links the mechanical action of the clamping mechanism with the on-off control of the drip irrigation pipe. Each placement port is equipped with an independent control unit triggered by the seedling pot. When the seedling pot is placed, its gravity drives the clamping mechanism to rotate, and simultaneously releases the pressure on the drip irrigation pipe, and irrigation begins; When the seedling pot is taken out, the clamping mechanism is reset under the action of the elastic element (62) and re-closes the drip irrigation pipe, so that water and nutrient solution can be accurately delivered to each seedling pot that actually contains seedlings, completely avoiding the phenomenon of upper layer interception and lower layer drought in the traditional method, and also eliminating ineffective irrigation and liquid waste in empty positions.

[0014] 2. Improved utilization of transportation space and physical safety of seedlings; Through the stacking design of the bearing unit and support rod, a stable multi-layer bearing structure is formed in the limited box space, increasing the number of seedlings transported at one time. At the same time, the placement port on the bearing plate, the support frame, and the clamping mechanism with elastic positioning and clamping parts work together to effectively and flexibly clamp and limit the seedling pots during transportation bumps, preventing them from shaking, tipping over or colliding with each other, effectively reducing the risk of physical damage to seedlings.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Reference Figure 1-6 A fresh transport box for Angelica seedlings includes a box body 1, a carrying unit 2, and a drip irrigation system. The purpose of the transport box is to ensure that each Angelica seedling receives precise and uniform water and nutrient supply during multi-layer stacking and transport, thereby significantly improving the survival rate and freshness of the seedlings.

[0019] The box 1 serves as a carrier container, providing support and protection for its internal structure. To maintain air circulation inside the box 1 and prevent excessive humidity from causing seedlings to mold, ventilation openings 11 are provided on the side wall of the box 1. The internal space of the box 1 is used to accommodate multiple carrier units 2 stacked longitudinally. In this embodiment, the carrier unit 2 is a carrier plate with several support rods 21 fixed at its bottom. This ensures that when multiple carrier units 2 are stacked longitudinally inside the box 1, a stable space can be formed between the upper and lower layers, ensuring that the branches and leaves of the seedlings in the lower layer have enough room to extend and will not be damaged by the upper carrier unit 2.

[0020] Each supporting unit 2 is processed with multiple evenly distributed placement openings 22 for holding seedling pots 3 containing seedlings. To ensure that the seedling pots 3 are placed stably, a support frame 23 that matches the outline of the seedling pot 3 is connected below each placement opening 22. The support frame 23 can support the bottom of the seedling pot 3 and suspend it in the placement opening 22.

[0021] Reference Figure 1-6 To achieve independent fixation and precise irrigation for each seedling pot 3, this application provides a clamping mechanism 6 on the side of each placement opening 22. The clamping mechanism 6 includes a rotating block 61 mounted on the bearing unit 2 via a rotating shaft, and an elastic element 62 that provides a reset torque for the rotating block 61. The elastic element 62 is a torsion spring. A positioning part 64 bent inward toward the placement opening 22 is fixed to the upper part of the rotating block 61. The positioning part 64 is made of an elastic metal sheet and is shaped like an L-shaped hook. Another abutment part 65 that converges inward toward the placement opening 22 is fixed to the lower part of the rotating block 61. It is also made of an elastic metal sheet.

[0022] The drip irrigation system includes a liquid storage tank 4 located outside the housing 1 and a water distribution pipe 5 located below each layer of the support unit 2. The liquid storage tank 4 is equipped with a water pump for liquid transportation. The water pump (not shown in the attached figure) is a mature existing device. The water distribution pipe 5 is a main pipe, and a branch drip irrigation pipe 51 is connected to each placement port 22 above it, thereby distributing the liquid flow to each irrigation point.

[0023] The clamping mechanism 6 integrates the dual functions of clamping and fixing as well as flow control. On the rotating block 61, there is also a flow-cutting component 63, which is an eccentric pressure block protruding from the block. The water outlet end of the drip irrigation pipe 51 is passed through from below the bearing unit 2, guided and fixed on the positioning part 64, so that its pipe opening faces the center direction of the placement port 22. Subsequently, the pipe body of the drip irrigation pipe 51 is arranged on the action path of the flow-cutting component 63.

[0024] When the seedling pot 3 is not placed in the placement port 22, the rotating block 61 is in the first position under the action of the elastic element 62, and the flow interruption component 63 presses the drip irrigation pipe 51 to interrupt the flow. When the seedling tray 3 is placed in the placement port 22, the seedling tray 3 drives the rotating block 61 to rotate to the second position, the flow interruption component 63 releases the pressure on the drip irrigation pipe 51, and the drip irrigation pipe 51 is connected.

[0025] Reference Figure 1-6 Specifically, when the placement opening 22 is empty, the rotating block 61, driven by the elastic element 62, is in the first position, that is, the positioning part 64 flips outward to its limit position and the pressing part 65 flips inward to its limit position. At this time, the flow-cutting component 63 presses against the drip irrigation pipe 51, using the deformation of the hose to close its cavity, thereby achieving flow cut-off and effectively preventing liquid waste. When it is necessary to place the seedling pot 3, the seedling pot 3 is manually placed downward into the placement opening 22. During this process, the pot wall of the seedling pot 3 will first contact and press the pressing part 65. Since the pressing part 65 is an inwardly contracting elastic metal sheet, after being subjected to outward pressing force, it will drive the entire rotating block 61 to overcome the torque of the elastic element 62 and rotate. The rotating block 61 rotates from the first position to a new second position, thus cutting off the flow. As component 63 moves away, it no longer presses against the drip irrigation pipe 51. The hose recovers its diameter through its own elasticity and begins to drip liquid into the corresponding seedling pot 3. At the same time, the positioning part 64 on the upper part of the rotating block 61 presses against the outer wall of the seedling pot 3 and is in a deformed state during the position change. When it reaches the second position, it resets so that its L-shaped end just fits into the upper edge of the seedling pot 3. Under the elastic force of the elastic metal sheet, the seedling pot 3 is flexibly clamped from above, which achieves the positioning and anti-shaking effects. When removing the seedling pot 3, only upward force needs to be applied. The upper edge of the seedling pot 3 overcomes the elastic force of the positioning part 64 and deforms and expands slightly, so it can be easily removed. At the same time, the rotating block 61 automatically resets to the first position under the action of the elastic component 62 and closes the drip irrigation pipe 51 again through the flow cut-off component 63 to stop irrigation.

[0026] Reference Figure 1-6 In order to achieve centralized water supply for the multi-layer bearing unit 2, a vertical connecting pipe is installed on the water distribution pipe 5 of each layer. The connecting pipe includes a main connector 52 and a secondary connector 53. The bottom of the box 1 is also equipped with a main connector 52 that communicates with the liquid storage tank 4.

[0027] Specifically, the lowest layer support unit 2 located at the bottom of the box 1 has its secondary connector 53 connected to the main connector 52 of the liquid storage tank 4, thus achieving communication with the liquid storage tank 4. When multiple layers are stacked, the secondary connector 53 of the upper layer support unit 2 will be precisely aligned and inserted into the main connector 52 of the lower layer support unit 2 to form a sealed connection. By connecting layer by layer in this way, a vertical water supply network is constructed from the bottom liquid storage tank 4 to the top layer, ensuring that each layer can obtain a stable liquid source. For the uppermost support unit 2, it no longer needs to be connected upwards, so its main connector 52 is sealed with a plug to prevent liquid leakage.

[0028] To further enhance the seedling preservation function during transportation, the drip irrigation system of this application can be set up in two sets, each with its own independent liquid storage tank 4, water distribution pipe 5, and drip irrigation pipe 51. One set of drip irrigation system can be used to drip irrigation with clean water to supplement moisture; the other set of drip irrigation system can be used to drip irrigation with nutrient solution to continuously supply nutrients to the seedlings during long-distance transportation. These two modes can be flexibly activated according to the transportation time and seedling condition, which greatly improves the preservation effect of seedlings and their robustness after survival.

[0029] The specific working process of this utility model is as follows: Idle state (flow interruption): When the seedling pot 3 is not placed in the placement port 22, the rotating block 61 of the clamping mechanism 6 is in the first position under the drive of the elastic element 62. At this time, the flow interruption component 63 on the rotating block 61 will press against the soft drip irrigation tube 51, causing its cavity to close and the flow interruption to be achieved, effectively preventing liquid waste.

[0030] Seedling placement (conduction and fixation): When the seedling pot 3 is placed into the placement opening 22, its pot wall will first contact and press the clamping part 65 of the clamping mechanism 6. This outward force drives the entire rotating block 61 to rotate against the torque of the elastic element 62, rotating from the first position to the second position.

[0031] Irrigation connection: The rotation of the rotating block 61 causes the flow interruption component 63 on it to move away, no longer pressing on the drip irrigation pipe 51. The drip irrigation pipe 51 restores its flow diameter by its own elasticity and begins to stably drip liquid into the corresponding seedling pot 3.

[0032] Pot fixing: At the same time, during the rotation of the positioning part 64 on the upper part of the rotating block 61, its L-shaped end will be inserted into the upper edge of the seedling pot 3. Under the elastic force of the positioning part 64, the positioning part 64 flexibly clamps the seedling pot 3 from above, which achieves reliable positioning and anti-shaking effect.

[0033] Removing the seedlings (restoring the interruption): When it is necessary to remove the seedling pot 3, applying upward force will cause the upper edge of the pot to overcome the elasticity of the positioning part 64 and deform outward, so as to remove it smoothly. Once the seedling pot 3 is removed, the rotating block 61 will automatically return to the first position under the action of the elastic element 62, and the drip irrigation pipe 51 will be closed again by the interruption component 63 to stop irrigation.

[0034] The working process of the water supply network is as follows: Liquid flows out from the storage tank 4 outside the tank 1, enters the water distribution pipe 5 of the lowest layer bearing unit 2 through the main connector 52 connected to the bottom of the tank, and when multiple layers of bearing units 2 are stacked, the auxiliary connector 53 of the upper layer bearing unit 2 will be sealed and connected with the main connector 52 of the lower layer bearing unit 2, thereby constructing a vertical water supply network from the bottom layer to the top layer, ensuring that the water distribution pipe 5 of each layer can obtain liquid source, and the water distribution pipe 5 then distributes the liquid to each drip irrigation pipe 51 to complete the liquid transportation.
