Description

Technical Field

[0001] This utility model relates to the technical field of hydroponic alfalfa cutting boxes, and in particular to a portable hydroponic alfalfa cutting box. Background Technology

[0002] Alfalfa, a high-quality legume forage, is widely used in animal husbandry. Hydroponic propagation is a crucial method for efficiently cultivating robust seedlings and a common and important seedling cultivation method in daily scientific research. Hydroponic propagation, with its advantages of controllable water and fertilizer environment, short cycle (15-20 days), high seedling survival rate (over 90%), and stable preservation of the mother plant's superior traits (such as stress resistance and high photosynthetic efficiency), has become a core technology for cultivating high-quality alfalfa seedlings. To meet the needs of alfalfa propagation in terms of environmental humidity, nutrient supply, and ease of operation, portable hydroponic propagation boxes have emerged. These devices need to balance structural stability and operational flexibility, providing a suitable growth environment for the cuttings while being easy to carry and operate, adapting to cultivation needs in different scenarios, and promoting the development of large-scale alfalfa seedling cultivation technology.

[0003] Most existing alfalfa hydroponic cutting devices employ a fixed frame structure, where the cutting board is bolted to the cultivation box. Nutrient solution is delivered via a piping system, and internal humidity is maintained by covering with a film or humidity-regulating cover. The underlying technology primarily involves manually controlling the timed and quantitative supply of nutrient solution, combined with a temperature control device to regulate the ambient temperature, providing stable water, fertilizer, and air conditions for the cutting roots, thus promoting root germination and plant growth.

[0004] However, in the existing technology, the connection between the cutting board and the cultivation box relies on fasteners such as bolts. Disassembly and assembly require the use of special tools such as screwdrivers, and the operation steps are cumbersome. Especially when working outdoors or in the field, it is inconvenient to carry tools, making the maintenance, replacement and movement of the cutting board very difficult, which greatly affects the work efficiency and makes it difficult to meet the actual needs of quick disassembly and assembly. Therefore, a portable hydroponic cutting box for alfalfa is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable hydroponic cutting box for alfalfa, which aims to improve the problem that the existing technology requires multiple tools to disassemble the cutting board, making it difficult to disassemble conveniently.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable hydroponic cutting box for alfalfa includes a cutting box, a cutting plate inside the cutting box, multiple cutting holes inside the cutting plate, a disassembly and assembly component inside the cutting plate, an inclined drainage pipe fixedly connected inside the cutting box, and a moisture-retaining component on the top of the cutting box.

[0008] The assembly / disassembly assembly includes multiple retaining balls, the outer walls of which are slidably connected to the inside of the cutting plate. Multiple slots are formed inside the cutting plate. The outer walls of the retaining balls are slidably connected to the inside of the cutting box. One end of each retaining ball is fixedly connected to a sliding post, and the other end of the sliding post is fixedly connected to a limiting disc. The outer wall of the limiting disc is slidably connected to the inside of the cutting box. A spring is installed inside the cutting box, one end of which is fixedly connected to the outer wall of the limiting disc, and the other end of which is fixedly connected to the inner wall of the cutting plate. Multiple water inlet components are installed inside the cutting plate.

[0009] As a further description of the above technical solution:

[0010] The moisturizing component includes a moisturizing cover, the outer wall of which is rotatably connected to the outer wall of the cutting box. A slot is provided inside the cutting box. An elastic card is fixedly connected to one side of the moisturizing cover, and the outer wall of the elastic card is slidably connected to the slot.

[0011] As a further description of the above technical solution:

[0012] The water inlet assembly includes a water inlet pipe, the outer wall of which is fixedly connected to the inner wall of the cutting plate.

[0013] As a further description of the above technical solution:

[0014] The water inlet pipe has an inlet, and multiple connecting columns are fixedly connected inside the water inlet pipe.

[0015] As a further description of the above technical solution:

[0016] The other end of the connecting column is fixedly connected to a fixed housing, and a transmission column is slidably connected inside the fixed housing.

[0017] As a further description of the above technical solution:

[0018] A sealing plug is fixedly connected to the top of the transmission column, and the outer wall of the sealing plug is slidably connected to the inside of the water inlet.

[0019] As a further description of the above technical solution:

[0020] The bottom end of the transmission column is fixedly connected to a limiting disk, and the outer wall of the limiting disk is slidably connected inside the fixed housing.

[0021] As a further description of the above technical solution:

[0022] A second spring is provided inside the fixed outer shell. The top end of the second spring is fixedly connected to the bottom end of the limiting disc, and the bottom end of the second spring is fixedly connected to the inner wall of the fixed outer shell.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the ball-holding mechanism achieves its sliding function by pulling the groove. When the groove is pulled, the groove drives the sliding column and the limiting disc, and in conjunction with the spring, the ball-holding mechanism slides inside the cutting box, thereby facilitating the disassembly and assembly of the cutting plate. This makes it convenient for maintenance, replacement, and movement, and solves the problem that existing methods of disassembling and assembling cutting plates require multiple tools and are not easy to disassemble, thus improving the convenience of disassembly and assembly of cutting plates.

[0025] 2. In this utility model, the sealing plug achieves its movement function by the addition of nutrient solution. When the nutrient solution is added, the gravity of the nutrient solution drives the transmission column and the limiting disc, and in conjunction with the second spring, the sealing plug slides inside the water inlet, thereby allowing the nutrient solution to flow in one direction, avoiding overflow, solving the problem of easy splashing when shaking, and improving the stability of the nutrient solution placement.

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] Reference Figures 1-3 This utility model provides one embodiment: a portable hydroponic cutting box for alfalfa, including a cutting box 1, which is injection molded from food-grade PP material and has an overall rectangular structure, ensuring structural strength while being lightweight and portable, suitable for various scenarios such as outdoor use or laboratory use. The cutting box 1 has a cutting plate 4 inside, made of ABS engineering plastic, which fits snugly against the inner wall of the cutting box 1 and can be flexibly pulled out. The cutting plate 4 has multiple cutting holes 7 inside. The cutting holes 7 are arranged in a matrix to fix the stems of the alfalfa cuttings and prevent them from tipping over during hydroponics, while also reserving sufficient space for root growth. The cutting board 4 is equipped with a disassembly and assembly component. The cutting box 1 is fixedly connected to an inclined drainage pipe 6, which is made of PVC and is connected to the bottom of the cutting box 1 by hot-melt welding. The inclined angle is 15°, which facilitates the drainage of excess nutrient solution or water in the box and avoids water accumulation that could lead to root rot. The top of the cutting box 1 is equipped with a moisture-retaining component.

[0035] The assembly / disassembly component includes multiple retaining balls 9, the outer walls of which are slidably connected to the inside of the insert plate 4. The insert plate 4 has multiple pull grooves 10 inside, each a rectangular recess located on both sides of the insert plate 4, facilitating the operator's fingers to insert and pull the insert plate 4. The outer walls of the retaining balls 9 are slidably connected to the inside of the insert box 1. One end of each retaining ball 9 is fixedly connected to a sliding post 11, and the other end of the sliding post 11 is fixedly connected to a limiting disc 12. The limiting disc 12 is a plastic disc and is threadedly connected to the sliding post 11. The outer wall of the limiting disc 12 is slidably connected to the inside of the insert box 1. The cutting box 1 is equipped with a spring 13. One end of the spring 13 is fixedly connected to the outer wall of the limiting disc 12, and the other end of the spring 13 is fixedly connected to the inner wall of the cutting plate 4. The cutting plate 4 is equipped with multiple water inlet components. The moisturizing components include a moisturizing cover 2. The moisturizing cover 2 is made of transparent PC material, which can ensure light transmission and facilitate observation of the growth of the cuttings inside. The outer wall of the moisturizing cover 2 is rotatably connected to the outer wall of the cutting box 1. The cutting box 1 has a slot 5 inside. An elastic card plate 3 is fixedly connected to one side of the moisturizing cover 2. The outer wall of the elastic card plate 3 is slidably connected to the inside of the slot 5.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The water inlet assembly includes a water inlet pipe 8, made of food-grade PVC and cylindrical in shape. Its outer wall is fixedly connected to a pre-drilled mounting hole on the inner wall of the cutting plate 4 via hot-melt welding. The water inlet pipe 8 provides a dedicated channel for injecting nutrient solution, preventing the solution from impacting the alfalfa cuttings when poured directly into the cutting holes 7. The outer wall of the water inlet pipe 8 is fixedly connected to the inner wall of the cutting plate 4. An inlet 15 is provided inside the water inlet pipe 8; the inlet 15 is a tapered hole, wider at the top and narrower at the bottom, facilitating the smooth flow of nutrient solution and ensuring a better fit with the sealing plug 14, enhancing the sealing effect. Multiple connecting posts 17 are fixedly connected inside the water inlet pipe 8, with a fixed outer shell 18 fixedly connected to the other end of each connecting post 17. A transmission column 16 is slidably connected inside the fixed housing 18. A sealing plug 14 is fixedly connected to the top of the transmission column 16. The sealing plug 14 is made of silicone and has a conical structure that matches the shape of the water inlet 15. Its outer wall is slidably connected to the inside of the water inlet 15. The sealing plug 14 is used to seal the water inlet 15 when no nutrient solution is injected to prevent water evaporation or nutrient solution splashing out of the box. The outer wall of the sealing plug 14 is slidably connected to the inside of the water inlet 15. A limiting disc 19 is fixedly connected to the bottom of the transmission column 16. The outer wall of the limiting disc 19 is slidably connected to the inside of the fixed housing 18. A second spring 20 is provided inside the fixed housing 18. The top of the second spring 20 is fixedly connected to the bottom of the limiting disc 19, and the bottom of the second spring 20 is fixedly connected to the inner wall of the fixed housing 18.

[0037] Working principle: When placing the cutting plate 4, first align the cutting plate 4 with the opening of the cutting box 1. Then, using the pull grooves 10 on both sides of the cutting plate 4, apply a pushing force to drive the cutting plate 4 smoothly into the inner wall of the cutting box 1. At this time, the retaining ball 9 installed on the edge of the cutting plate 4 will first contact the inner wall of the cutting box 1. Since the surface of the retaining ball 9 is a smooth arc, under the squeezing action of the inner wall of the cutting box 1, the retaining ball 9 will automatically retract and slide into the cutting plate 4. The movement of the retaining ball 9 will simultaneously drive the sliding column 11 connected to it to slide in the reserved channel, thereby pushing the limiting disk 12 at the end of the sliding column 11 to compress the spring 13, so that the spring 13 is in an energy storage state. When the cutting plate 4 slides to the preset appropriate position, the locking ball 9 is precisely aligned with the positioning groove on the inner wall of the cutting box 1. At this time, the spring 13 will quickly rebound, pushing the limiting disc 12, the sliding column 11 and the locking ball 9 to reset. The locking ball 9 is accurately embedded in the groove, realizing the stable placement of the cutting plate 4 inside the cutting box 1, effectively avoiding shaking or displacement.

[0038] In addition, during the nutrient solution addition process, the nutrient solution should be slowly poured into the inlet 15. As the nutrient solution level rises, its gravity gradually acts on the sealing plug 14 inside the inlet 15. When the gravity exceeds the elastic force of the second spring 20, the sealing plug 14 is pushed out of the inlet 15, opening the channel. The movement of the sealing plug 14 will drive the connected transmission column 16 to move synchronously. The limiting disc 19 at the other end of the transmission column 16 slides in the guide rail inside the fixed housing 18, continuously compressing the second spring 20. When the nutrient solution reaches the appropriate concentration, the pouring operation is stopped. At this time, the rebound force of the second spring 20 will push the limiting disc 19, the transmission column 16, and the sealing plug 14 to reset. The sealing plug 14 is then tightly embedded back into the inlet 15, completing the channel sealing. This effectively prevents the nutrient solution from splashing out when the device is shaken, ensuring accurate retention of the nutrient solution.
