Description

Technical Field

[0001] This utility model relates to the field of fresh-cut flower transportation technology, specifically a fresh-cut flower storage device that can prevent flowers from being squeezed during transportation. Background Technology

[0002] Flowers occupy an important place in people's lives, decorating them and serving as a medium to improve their quality of life. People's love for flowers and the differences in their living environments have promoted the development of flower distribution and the flower industry. Flowers require storage devices to protect them during transportation.

[0003] A Chinese patent publication (CN222330357U) discloses a fresh-cut flower storage device that prevents flowers from being crushed during transportation. The operation process is as follows: first, the placement rack is pulled out from the support frame; then, the clamps are opened, and the fresh-cut flowers are placed on the rack, allowing the silicone pad to contact the flower stems to reduce the contact force between the flower heads and the rack; subsequently, water is sprayed onto the sponge block; finally, the clamps are fastened to further secure the fresh-cut flowers, thus completing the storage. However, this device still has the following shortcomings: Firstly, no independent protective space was built for each cut flower. After the cut flowers were fixed to the rack with the clamps, although the contact force between the flower head and the rack was reduced by the silicone pad, there was no effective isolation structure between the flower heads. The flower head may still come into contact with the edge of the rack or adjacent cut flowers. During transportation, the flower head is easily shaken and collides with surrounding parts or other flower heads, which can cause squeezing damage and make it difficult to ensure the integrity of the petals and the quality of the cut flowers. Secondly, the placement rack adopts a drawer-type pull-out structure, which can realize the loading and unloading operation of the base. However, due to the space limitation of the support frame and the limiting plate, the operable area after the placement rack is pulled out is limited to the local space that is pulled out. When the staff clamps the fresh cut flowers, they need to adjust the position of the flower stem and the angle of the clamp within a narrow range. This is not only easily constrained by space, causing inconvenience to the operation, but may also damage the petals due to insufficient operating space, further reducing the clamping efficiency. Third, it only focuses on achieving storage protection through the partition structure, and the moisturizing method relies on the sponge block spraying water once. The water is easily depleted due to evaporation or absorption too quickly, and it cannot continuously replenish the water and nutrients for cut flowers. In addition, the moisturizing function of the sponge block, the fixing function of the clamp, and the partitioning function of the placement rack lack linkage design, so it cannot achieve long-term maintenance while ensuring the protective effect, and it is difficult to meet the needs of continuous maintenance for long-distance transportation of cut flowers. Utility Model Content

[0004] The purpose of this invention is to provide a fresh-cut flower storage device that can prevent flowers from being squeezed during transportation. This addresses the shortcomings of existing devices, such as the lack of independent protection for each fresh-cut flower, the easy collision and squeezing of flower heads, which damages petals and ruins the appearance; the narrow operating space of the drawer-type storage rack, which is inconvenient for clamping and easily damages petals, resulting in low efficiency; and the reliance on sponge blocks for single spraying of water to maintain moisture, which lacks functional linkage and cannot provide long-term maintenance, making it difficult to meet the needs of long-distance transportation.

[0008] Furthermore, the nutrient solution spraying and protection unit includes a transparent protective cover, an atomizing nozzle located at the top inside the transparent protective cover, a branch pipe communicating with the atomizing nozzle, and a metal reinforcing sleeve fitted over the outer wall of the branch pipe; one end of the branch pipe penetrates the top of the transparent protective cover and extends to its outer side; both ends of the metal reinforcing sleeve are respectively connected to the outer side of the transparent protective cover and the outer wall of the horizontal pipe; the end of the branch pipe away from the atomizing nozzle is connected to the outer wall of the horizontal pipe.

[0009] Furthermore, the inner wall of the transparent protective cover is provided with a buffer sponge layer, and the atomizing nozzle is located inside the buffer sponge layer and does not contact the buffer sponge layer; the top of the buffer sponge layer is provided with a perforation adapted to the outer diameter of the branch pipe, and the branch pipe passes through the perforation and fits tightly against the inner wall of the perforation.

[0010] Furthermore, the outer wall of the transparent protective cover is provided with a plurality of vent holes evenly spaced along the circumference; the vent holes are located below the buffer sponge layer, and the height of the vent holes is not lower than the top of the insertion hole.

At the same time, the protection units work together with the nutrient solution delivery system to continuously and evenly replenish nutrients through atomizing nozzles, replacing the temporary moisturizing of existing sponge blocks, solving the problem of nutrient supply during long-distance transportation, and meeting the comprehensive needs of fresh-cut flower transportation.

[0017] Please see Figure 1-6 A fresh-cut flower storage device that avoids flower compression during transportation includes a nutrient solution tank 1, multiple insertion holes 2 spaced apart along the length of the nutrient solution tank 1, and elastic silicone sleeves 3 disposed on the inner walls of the insertion holes 2. It also includes side plates 17 perpendicularly connected to both ends of the nutrient solution tank 1, electric push rods 13 disposed at both upper ends of the nutrient solution tank 1, a rotary drive mechanism and a transmission mechanism connected to the output ends of the two electric push rods 13, a nutrient solution delivery system connected to the output end of the rotary drive mechanism and arranged laterally along the length of the nutrient solution tank 1, and multiple nutrient solution spraying and protection units connected to the lower outer wall of the nutrient solution delivery system and spaced apart along its length. Each of the multiple nutrient solution spraying and protection units corresponds one-to-one with each of the multiple insertion holes 2. One end of the nutrient solution delivery system extends into the interior of the nutrient solution tank 1. The rotary drive mechanism and the transmission mechanism slide in cooperation with the inner walls of the corresponding side plates 17. The end of the nutrient solution delivery system furthest from the rotary drive mechanism is rotatably connected to the transmission mechanism.

[0018] The nutrient solution tank 1 has a drain pipe connected to the bottom of one side, and a valve is fixedly installed on the outer wall of the drain pipe (to control the flow rate and flow of the drain), which facilitates the periodic discharge of residual old nutrient solution or cleaning wastewater in the tank. At the same time, the nutrient solution tank 1 has a filling pipe connected to the top of one side, which facilitates the replenishment of new nutrient solution into the tank, realizing convenient replacement and replenishment of nutrient solution and ensuring the maintenance needs of cut flowers.

[0019] This application further proposes that the nutrient solution delivery system includes a horizontal pipe 5 arranged transversely along the length of the nutrient solution tank 1, a flexible hose 10 sealed and connected to the outer wall of the horizontal pipe 5, a miniature water pump 11 sealed and connected to one end of the flexible hose 10, and a delivery pipe 12 sealed and connected to the water inlet port of the miniature water pump 11; the miniature water pump 11 is located on the upper side of the nutrient solution tank 1; one end of the delivery pipe 12 penetrates the upper side of the nutrient solution tank 1, and a fluororubber sealing sleeve is provided at the penetration point, and one end of the delivery pipe 12 extends to the bottom of the inside of the nutrient solution tank 1.

[0020] The micro water pump 11 is fixed to the upper side of the nutrient solution tank 1 by a bracket; the other end of the delivery pipe 12 extends vertically downward through the upper side of the nutrient solution tank 1, and a fluororubber sealing sleeve is fitted at the penetration point (the inner wall of the sealing sleeve is tightly fitted with the outer wall of the delivery pipe 12, and the outer wall is fixed with the inner wall of the penetration hole of the nutrient solution tank 1). Finally, the end of the delivery pipe 12 away from the micro water pump 11 extends to the bottom of the nutrient solution tank 1, ensuring that the nutrient solution at the bottom of the tank can be drawn.

[0021] Specifically, the fluororubber sealing sleeve at the penetration point of the delivery pipe 12 can effectively prevent the nutrient solution from leaking during the delivery process, avoid wasting the nutrient solution, and prevent the leaked liquid from contaminating the cut flowers or other parts of the device; the delivery pipe 12 extends to the bottom of the nutrient solution tank 1, which can maximize the extraction of nutrient solution in the tank; the flexible characteristics of the hose 10 can be adapted to the rotation of the horizontal pipe 5 with the rotation drive mechanism, avoiding pipe pulling damage caused by rigid pipe connection.

[0022] This application further proposes that the rotary drive mechanism includes a mounting frame 14 connected to the output end of an electric push rod 13 and a servo motor 15 mounted inside one side of the mounting frame 14; the transmission mechanism includes a mounting base 16 connected to the output end of another electric push rod 13; the output end of the servo motor 15 is connected to one end of the horizontal tube 5 via a coupling, and the end of the horizontal tube 5 near the servo motor 15 is connected to the flexible hose 10; the other end of the horizontal tube 5 is rotatably connected to one side of the mounting base 16 via a bearing; each of the two side plates 17 has a vertically extending groove 18 on its opposite side, and a slider 19 is slidably fitted inside the groove 18; the two sliders 19 are respectively connected to the outer walls of the mounting frame 14 and the mounting base 16.

[0023] Specifically, the rotary drive mechanism and the transmission mechanism are connected to the electric push rod 13 through the mounting frame 14 and the mounting base 16, respectively. With the slider 19 sliding in the slide groove 18, the horizontal tube 5 can be smoothly raised and lowered under the drive of the electric push rod 13, providing a stable motion trajectory for the picking and placing of fresh-cut flowers and the closing of the protective cover. The servo motor 15 drives the horizontal tube 5 to rotate through the coupling. The other end of the horizontal tube 5 is rotatably connected to the mounting base 16 through the bearing, ensuring that the horizontal tube 5 rotates smoothly and making it easy to adjust the angle of the transparent protective cover 8.

[0024] This application further proposes that the nutrient solution spraying and protection unit includes a transparent protective cover 8, an atomizing nozzle 7 located at the top inside the transparent protective cover 8, a branch pipe 6 sealed and connected to the water inlet port of the atomizing nozzle 7, and a metal reinforcing sleeve 9 sleeved on the outer wall of the branch pipe 6; one end of the branch pipe 6 penetrates the top of the transparent protective cover 8 and extends to its outer side; both ends of the metal reinforcing sleeve 9 are respectively connected to the outer side of the transparent protective cover 8 and the outer wall of the horizontal pipe 5; the end of the branch pipe 6 away from the atomizing nozzle 7 is connected to the outer wall of the horizontal pipe 5.

[0025] Specifically, the metal reinforcing sleeve 9 is connected to the transparent protective cover 8 and the horizontal pipe 5 at both ends, which can reinforce the connection between the branch pipe 6 and the two, prevent the branch pipe 6 from loosening or falling off due to transportation bumps, and at the same time distribute the weight of the transparent protective cover 8 on the branch pipe 6 to prevent the branch pipe 6 from bending and breaking, ensuring the smooth flow of nutrient solution. The atomizing nozzle 7 is located at the top inside the transparent protective cover 8, which can atomize the nutrient solution and spray it evenly on the cut flowers inside the protective cover. In conjunction with the protective function of the transparent protective cover 8, it can continuously replenish nutrients to the cut flowers while avoiding the flowers being squeezed and damaged during transportation, thus ensuring the quality of cut flower transportation in all aspects.

[0026] This application further proposes that a buffer sponge layer 20 is tightly fitted to the inner wall of the transparent protective cover 8, and the atomizing nozzle 7 is located inside the buffer sponge layer 20 and does not contact the buffer sponge layer 20; the top of the buffer sponge layer 20 is provided with a perforation 21 that matches the outer diameter of the branch pipe 6, and the branch pipe 6 passes through the perforation 21 and is tightly fitted to the inner wall of the perforation 21.

[0027] The inner wall of the transparent protective cover 8 is bonded to the cushioning sponge layer 20 with food-grade adhesive. The adhesive coating is evenly distributed on the outer wall of the cushioning sponge layer 20, ensuring that the cushioning sponge layer 20 is firmly fixed inside the transparent protective cover 8, and allowing for easy replacement by external force when the cushioning sponge layer 20 becomes worn, damp, or contaminated due to long-term use. At the same time, a perforation 21 is opened through the top of the cushioning sponge layer 20. The inner diameter of the perforation 21 is adapted to the outer diameter of the branch pipe 6. The end of the branch pipe 6 away from the horizontal pipe 5 passes through the top of the transparent protective cover 8 and the perforation 21 of the cushioning sponge layer 20, and then connects to the atomizing nozzle 7. The outer wall of the branch pipe 6 is tightly fitted to the inner wall of the perforation 21, realizing the positioning and fixation of the cushioning sponge layer 20 inside the transparent protective cover 8. The cushioning sponge layer 20 is an open-cell polyurethane foam material with good energy absorption, cushioning, and breathability.

[0028] Specifically, the buffer sponge layer 20 fits against the inner wall of the transparent protective cover 8 and wraps around the atomizing nozzle 7, which can provide a flexible buffer for the cut flowers during transportation and prevent the flowers from colliding and being squeezed by the hard inner wall of the transparent protective cover 8, effectively protecting the integrity of the petals; the atomizing nozzle 7 does not come into contact with the buffer sponge layer 20, which can prevent the buffer sponge layer 20 from blocking the spray range of the nozzle, ensuring that the atomized nutrient solution can evenly cover the flowers, while avoiding the buffer sponge layer 20 absorbing too much nutrient solution.

[0029] This application further proposes that the outer wall of the transparent protective cover 8 is provided with a plurality of vent holes 24 evenly spaced along the circumference; the vent holes 24 are located below the buffer sponge layer 20, and the height of the vent holes 24 is not lower than the top of the insertion hole 2.

[0030] The inner wall of the ventilation hole 24 is covered with a dustproof net (to prevent dust from entering); the opening height of the multiple ventilation holes 24 is consistent and located below the buffer sponge layer 20 on the inner wall of the transparent protective cover 8; at the same time, the height of the ventilation hole 24 is not lower than the top of the insertion hole 2 on the nutrient solution tank 1, ensuring that when the bottom of the transparent protective cover 8 is embedded in the annular groove 25, the ventilation hole 24 will not be blocked by the upper surface of the nutrient solution tank 1, and can form a connection with the internal space and external environment of the transparent protective cover 8, without overlapping with the buffer area of ​​the buffer sponge layer 20, and corresponding to the flower growth area after the cut flowers are inserted into the insertion hole 2.

[0031] Specifically, the ventilation holes 24 can continuously provide fresh air to the cut flowers inside the protective cover, preventing the flowers from withering due to lack of oxygen in the sealed environment and ensuring the survival quality of the cut flowers during transportation.

[0032] This application further proposes that a plurality of reflux holes 4 are provided through the upper side of the nutrient solution tank 1, and the plurality of reflux holes 4 are arranged in a ring at uniform intervals along the outer periphery of each insertion hole 2; a plurality of annular grooves 25 adapted to the bottom outer diameter of the corresponding transparent protective cover 8 are provided on the upper side of the nutrient solution tank 1, and the bottom of the transparent protective cover 8 can be embedded in the annular grooves 25; the plurality of reflux holes 4 are located inside the annular grooves 25.

[0033] Specifically, a silicone sealing ring is attached to the inner wall of the annular groove 25; the fitting and embedding design of the annular groove 25 and the transparent protective cover 8 can not only position the transparent protective cover 8 to prevent it from shifting or falling out of the corresponding position of the insertion hole 2 due to transportation bumps, but also form a preliminary seal between the bottom of the transparent protective cover 8 and the annular groove 25 to reduce nutrient solution leakage; the return hole 4 inside the annular groove 25 can recover excess atomized nutrient solution in the transparent protective cover 8. During the spraying process, the nutrient solution that is not absorbed by the cut flowers will drip down the inner wall of the protective cover into the annular groove 25, and then flow back into the nutrient solution tank 1 through the return hole 4, realizing the recycling of nutrient solution and reducing resource waste and maintenance costs.

[0034] This application further proposes that a plurality of support rods 22 are fixedly installed on the upper side of the nutrient solution tank 1 by bolts, and a U-shaped bracket 23 is fixedly connected to the upper end of the support rod 22 by welding; the inner side of the U-shaped bracket 23 slides in contact with the outer wall of the horizontal tube 5; the support rod 22 is located between two adjacent annular grooves 25.

[0035] Among them, the support rods 22 are distributed at intervals along the length of the nutrient solution tank 1, and each support rod 22 is located between two adjacent annular grooves 25; the U-shaped bracket 23 has an arc-shaped structure with the opening facing upward, and its inner arc surface maintains sliding contact with the outer wall of the horizontal tube 5, which can form vertical support for the horizontal tube 5.

[0036] Specifically, the support rod 22 and the U-shaped bracket 23 work together to form the support structure of the horizontal pipe 5, which can bear the weight of the horizontal pipe 5 and the nutrient solution spraying and protection unit, and prevent the horizontal pipe 5 from sagging or deforming due to its own weight or transportation bumps, thus ensuring the smooth flow of the nutrient solution delivery channel.

[0037] This application further proposes that a battery 26 is installed on one side of a side plate 17; the battery 26 is electrically connected to an electric push rod 13, a servo motor 15, and a micro water pump 11 respectively.

[0038] One of the side panels 17 has a waterproof plastic box installed on one side. The outer wall of the waterproof plastic box has heat dissipation holes, and the battery 26 is located inside the waterproof plastic box. The battery 26 (capacity 12V / 5Ah, with USB charging interface) is connected to the electric push rod 13, servo motor 15 and micro water pump 11 through wires to form independent power supply circuits.

[0039] Specifically, the use of a storage battery 26 to centrally power the electric push rod 13, servo motor 15, micro water pump 11 and controller not only eliminates the dependence on external power sources, but also enables the device to work continuously in transportation scenarios without external power, thus improving the portability and applicability of the equipment.

[0040] A PLC controller is bolted to one side of a side plate 17. This controller is electrically connected to the electric push rod 13, the servo motor 15, and the micro water pump 11. It also has a built-in timer module to achieve automated timing control. The operator can preset the operating program through the controller. On the one hand, the operator can adjust the lifting and lowering timing and stroke of the electric push rod 13, the start and stop and speed of the servo motor 15. On the other hand, the operator can set the nutrient solution supply cycle of the micro water pump 11 (such as starting once every 4 hours and running for 5 minutes each time) with the help of the timer module. This ensures that the lifting, rotation and nutrient solution spraying of the device are connected in an orderly manner according to the coordinated logic, which avoids action conflicts and can replenish the fresh cut flowers with nutrients as needed.

[0041] It should be noted that the electric actuator 13, servo motor 15, micro water pump 11 and controller are all commercially available and mature products that can be purchased directly. Their specific models and specifications can be selected according to the actual application scenario. The staff does not need to understand the specific structure and working principle of these components. As long as the purchased products can operate normally, it will not affect the specific implementation of this utility model. Therefore, they will not be described in detail here.

[0042] Working Process and Principle: When using this cut flower storage device, the operator issues a command through the controller. First, the two electric push rods 13 start synchronously. The output ends of the electric push rods 13 extend upwards, driving the connected mounting frame 14 and mounting base 16 to rise synchronously. The mounting frame 14 and mounting base 16 slide smoothly along the vertically opened grooves 18 on the inner wall of the side plate 17 via the outer fixed sliders 19, thereby driving the horizontal tube 5 and the multiple transparent protective covers 8 connected below the horizontal tube to rise synchronously until the horizontal tube 5 is completely detached from the multiple U-shaped supports 23 below. Subsequently, the controller controls the servo motor 15 to start. The output end of the servo motor 15 drives the horizontal tube 5 to rotate around the axis through the coupling. The end of the horizontal tube 5 away from the servo motor 15 maintains a stable rotational engagement with the mounting base 16 through the bearing. Finally, the horizontal tube 5 and the multiple transparent protective covers 8 are rotated as a whole to the position with the opening facing upwards, leaving sufficient operating space for the operator to insert cut flowers on the upper side of the nutrient solution tank 1.

[0043] Next, the flower stems of the cut flowers are inserted one by one into the corresponding holes 2 on the nutrient solution tank 1. The inner diameter of the elastic silicone sleeve 3 on the inner wall of the hole 2 is slightly smaller than the diameter of the flower stem. Relying on the elasticity of the material, it adaptively clamps the flower stems of different thicknesses, which can not only fix the position of the flower stems, but also avoid squeezing and damaging the flower stems, and prevent the flower stems from shaking during transportation and causing the flowers to collide and squeeze each other. After clamping, the controller once again controls the servo motor 15 and the electric push rod 13, so that the bottom of the transparent protective cover 8 is completely embedded in the annular groove 25 on the upper side of the nutrient solution tank 1. At this time, the horizontal tube 5 is placed inside the multiple U-shaped brackets 23. The U-shaped brackets 23 provide stable support for the horizontal tube 5, preventing the horizontal tube 5 from shifting due to transportation bumps. At the same time, each transparent protective cover 8 creates an independent protective space for the corresponding flower, further isolating the risk of external squeezing.

[0044] After the device enters the operation phase, the nutrient solution supply cycle is set through the timer module built into the controller, triggering the micro water pump 11 to start at regular intervals. When the micro water pump 11 is working, it draws nutrient solution through the delivery pipe 12 extending to the bottom of the nutrient solution tank 1. The delivery pipe 12 passes through the fluororubber sealing sleeve on the upper side of the nutrient solution tank 1 and fits tightly against the pipe wall to effectively prevent nutrient solution leakage. After being pressurized by the micro water pump 11, the nutrient solution is delivered to the horizontal pipe 5 through the flexible hose 10. The nutrient solution in the horizontal pipe 5 is distributed through the branch pipes 6 to the atomizing nozzle 7 at the top of the transparent protective cover 8. The atomizing nozzle 7 atomizes the nutrient solution into fine water mist, which is evenly sprayed onto the petals and stems of the cut flowers, continuously providing water and nutrients to the flowers and preventing the flowers from wilting due to lack of water during transportation. In addition, the metal reinforcing sleeve 9 fitted on the outer wall of the branch pipe 6 is fixedly connected at both ends to the outer side of the transparent protective cover 8 and the outer wall of the horizontal pipe 5, which can enhance the connection stability of the branch pipe 6 and prevent the branch pipe from loosening or falling off due to transportation bumps.

[0045] The inner wall of the transparent protective cover 8 is lined with a soft, cushioning sponge layer 20, which provides flexible support for the flowers when the device is bumpy, further reducing damage from impacts and compression. The ventilation holes 24 on the outer wall of the transparent protective cover 8 (located below the cushioning sponge layer 20 and not lower than the top of the insertion hole 2) ensure air circulation inside the cover, preventing the flowers from wilting due to lack of oxygen. Simultaneously, excess nutrient solution during the atomized spraying process drips down the inner wall of the transparent protective cover 8 to the bottom, and then flows back to the nutrient solution tank 1 through the return hole 4 in the annular groove 25, achieving nutrient solution recycling, effectively reducing resource waste and lowering the cost of cut flower maintenance.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
