Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and more specifically, to an alfalfa seedling raising device. Background Technology

[0002] In the existing alfalfa cultivation technology field, the seedling raising devices commonly found on the market have some shortcomings in terms of structural design and functional configuration. The vast majority of these devices adopt a single-layer fixed structural layout. While this traditional single-layer design has relatively low manufacturing costs and is simple and easy to operate, its inherent structural defects lead to a series of problems such as low space utilization, limited cultivation scale, and poor adaptability. Specifically, a single-layer seedling raising device can only arrange a limited number of seedling boxes or cultivation containers on a single horizontal plane. When growers need to expand the seedling scale to meet the needs of seasonal concentrated sowing or large-scale planting, they can only achieve this by increasing the number of devices or occupying a larger area of ​​land. This not only increases equipment investment costs and site rental fees but also wastes valuable planting space such as greenhouses. More importantly, existing single-layer seedling raising devices generally lack flexible structural adjustment mechanisms and modular design concepts. The number and layout of cultivation boxes are fixed after the equipment is manufactured, without any... The existing equipment requires targeted adjustments based on the differentiated environmental factors such as light intensity, ventilation, and spatial density of alfalfa seedlings at different growth stages. However, when growers need to implement differentiated cultivation management for different batches or varieties of alfalfa seedlings, the fixed structure of the existing equipment makes it impossible for operators to easily and quickly increase or decrease the number of cultivation boxes to adapt to changes in the actual number of seedlings, nor can they flexibly adjust the vertical spacing and spatial layout of the cultivation boxes to optimize light distribution and ventilation. The installation and fixing methods of cultivation boxes usually adopt permanent or semi-permanent connection methods such as welding, bolting, or slot embedding. Although these traditional fixing methods can ensure the stability of the cultivation box installation, the disassembly and reinstallation process of cultivation boxes is extremely cumbersome and time-consuming when it is necessary to adjust the configuration of the seedling device or to perform equipment maintenance. Operators often need to use special tools such as wrenches and screwdrivers and spend a lot of manual time to complete the replacement or repositioning of a cultivation box, which increases the difficulty and labor cost of daily equipment maintenance. Utility Model Content

[0003] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an alfalfa seedling raising device to solve the technical problems mentioned in the background art.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An alfalfa seedling raising device includes a cultivation box with connecting rods connected to its four corners; it also includes a quick-assembly and disassembly mechanism, which includes a fixed cylinder with multiple sets of sliding grooves on its surface. An insert rod is slidably connected inside the fixed cylinder, and the surface of the insert rod has a locking groove. The lower end face of the fixed cylinder is fixedly connected to the upper end face of the connecting rod, and the other end of the connecting rod is fixedly connected to the upper end face of the insert rod. The insert rod is inserted into the fixed cylinder connected above the corresponding connecting rod of the next layer.

[0005] Preferably, the outer wall of the fixed cylinder is slidably connected with an upper inclined ring and a lower inclined ring, and the outer wall of the fixed cylinder is threadedly connected with an upper threaded sleeve and a lower threaded sleeve. The upper threaded sleeve is located above the upper inclined ring, and the lower threaded sleeve is located below the lower inclined ring. The upper and lower inclined rings can be moved by rotating the upper and lower threaded sleeves.

[0006] Preferably, an upper thrust bearing is provided between the upper threaded sleeve and the upper inclined ring, and a lower thrust bearing is provided between the lower threaded sleeve and the lower inclined ring. The upper and lower thrust bearings can effectively prevent the rotation of the upper and lower threaded sleeves from affecting the upper and lower inclined rings.

[0007] Preferably, the outer wall of the upper threaded sleeve is fitted with an upper rotating ring, and the outer wall of the lower threaded sleeve is fitted with a lower rotating ring. Multiple sets of connecting rods are connected between the upper and lower rotating rings. Both the upper and lower threaded sleeves are slidably connected to the connecting rods. The operator only needs to rotate one side of the rotating ring to drive the entire mechanism to operate in a coordinated manner, which simplifies the operation steps.

[0008] Preferably, the outer side of the fixed cylinder is provided with four sets of fixed plates, and the inner middle position of each set of fixed plates is provided with two sets of intermediate rods. The side wall of the intermediate rod is connected with a connecting spring. The four sets of fixed plates are connected by the connecting spring. The design of the connecting spring provides a stable preload and can drive the fixed plates to reset.

[0009] Preferably, the inner sidewall of the fixed plate is also provided with two sets of upper push rods and two sets of lower push rods. The upper push rods are adapted to the upper inclined ring, and the lower push rods are adapted to the lower inclined ring. The design of the upper and lower push rods converts the axial movement of the inclined ring into the radial thrust of the push rods.

[0010] Preferably, the side wall of the fixing plate is provided with two sets of locking rods that are adapted to the slot, and a vertical rod is connected between the two sets of locking rods. The locking rods are slidably connected to the sliding groove, and the locking and fixing of the locking rods and the slot can realize the fixing of the insertion rod.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides an alfalfa seedling raising device with the following beneficial effects: This alfalfa seedling raising device, through the design of a multi-layer adjustable spatial layout system with four corner connecting rods of the cultivation box and a quick disassembly mechanism, solves the shortcomings of traditional single-layer fixed seedling raising devices in terms of space utilization efficiency, structural adjustment flexibility, and ease of installation and disassembly. It realizes rapid response and adaptation of equipment configuration in the alfalfa seedling production process. The quick disassembly mechanism adopts a plug-in connection of fixed cylinder and plug rod as the basic connection method between upper and lower cultivation boxes, so that different layers of cultivation boxes can achieve standardized modular docking through connecting rods. Compared with the traditional welding or bolt fixing method, this plug-in structure design has the advantages of accurate installation positioning, simple disassembly and separation, and strong reusability, creating a structural foundation for the free combination and flexible configuration of multi-layer cultivation boxes.

[0012] The upper and lower inclined rings, slidably connected to the outer wall of the fixed cylinder, along with the upper and lower threaded sleeves, form a bidirectional symmetrical helical drive radial locking mechanism. The operator simply rotates the upper or lower rotating ring fitted on the outside of the threaded sleeve. The rotating rings, rigidly connected by multiple sets of connecting rods, achieve synchronous rotation of the upper and lower rotating rings, thereby driving the upper and lower threaded sleeves, with opposite thread directions, to move synchronously in opposite directions along the axial direction of the fixed cylinder. This bidirectional symmetrical drive method, based on the helical transmission principle, transforms simple rotational operation into controllable axial thrust. During axial movement, the inclined structure of the inclined ring generates radial thrust on the upper and lower push rods on the inner wall of the fixed plate, driving the fixed plate and locking rods to move outwards from the fixed cylinder. The device moves inwards towards the fixed cylinder under the rebound force of the connecting spring. The elasticity of the connecting spring provides both the driving force for the fixed plate to reset and the continuous and stable pre-tightening force for the locking state of the locking rod. Operators can quickly lock or unlock a single connection point by simply rotating the rotating ring by hand without using special tools, thus improving work efficiency. This quick assembly and disassembly capability allows growers to flexibly adjust the layer configuration and spatial layout of the seedling device according to seasonal changes, market demand, variety replacement, and other actual conditions. The modular design of the quick assembly and disassembly mechanism also facilitates daily maintenance, cleaning, disinfection, and component replacement. Operators can quickly disassemble a single-layer cultivation box for independent cleaning or repair without affecting the normal use of other layers, thus reducing maintenance costs.

[0018] Please see Figures 1-5An alfalfa seedling raising device includes a cultivation box 11 with connecting rods 12 connected to its four corners; it also includes a quick-assembly and disassembly mechanism, which includes a fixed cylinder 21 with multiple sets of sliding grooves 22 on its surface. An insertion rod 23 is slidably connected inside the fixed cylinder 21, and a slot 24 is provided on the surface of the insertion rod 23. The lower end of the fixed cylinder 21 is fixedly connected to the upper end of the connecting rod 12, and the other end of the connecting rod 12 is fixedly connected to the upper end of the insertion rod 23. The insertion rod 23 is inserted into the fixed cylinder 21 above the corresponding connecting rod 12 of the next layer. An upper inclined ring 25 and a lower inclined ring 26 are slidably connected to the outer wall of the fixed cylinder 21. An upper threaded sleeve 27 and a lower threaded sleeve 28 are threadedly connected to the outer wall of the fixed cylinder 21. The upper threaded sleeve 27 is located above the upper inclined ring 25, and the lower threaded sleeve 28 is located below the lower inclined ring 26. An upper thrust bearing 29 is provided between the upper threaded sleeve 27 and the upper inclined ring 25, and between the lower threaded sleeve 28 and the lower inclined ring 26. A lower thrust bearing 210 is provided. An upper rotating ring 211 is fitted on the outer wall of the upper threaded sleeve 27, and a lower rotating ring 212 is fitted on the outer wall of the lower threaded sleeve 28. Multiple sets of connecting rods 213 are connected between the upper rotating ring 211 and the lower rotating ring 212. Both the upper threaded sleeve 27 and the lower threaded sleeve 28 are slidably connected to the connecting rods 213. Four sets of fixing plates 214 are provided on the outer side of the fixed cylinder 21. Two sets of intermediate rods 215 are provided in the middle of the inner side of each set of fixing plates 214. A connecting spring 216 is connected to the side wall of plate 15. Four sets of fixing plates 214 are connected by the connecting spring 216. The inner side wall of the fixing plate 214 is also provided with two sets of upper push rods 217 and two sets of lower push rods 218. The upper push rods 217 are adapted to the upper inclined ring 25, and the lower push rods 218 are adapted to the lower inclined ring 26. The side wall of the fixing plate 214 is provided with two sets of locking rods 219 adapted to the locking groove 24. A vertical rod 220 is connected between the two sets of locking rods 219. The locking rods 219 are slidably connected to the sliding groove 22.

[0019] In this invention, the multi-layer culture box 11 can be quickly installed or disassembled according to actual needs. Specifically, when it is necessary to connect two layers of culture boxes 11, the insert rods 23 connected below the connecting rods 12 at the four corners of the upper culture box 11 are inserted into the fixing cylinders 21 connected above the connecting rods 12 at the four corners of the lower culture box 11. Then, the operator manually rotates the upper rotating ring 211 or the lower rotating ring 212. The upper rotating ring 211 or the lower rotating ring 212 drives the lower rotating ring 212 or the upper rotating ring 211 on the other side to rotate synchronously through the connecting rod 213. This drives the upper threaded sleeve 27 and the lower threaded sleeve 28, which are engaged with the connecting rod 213, to rotate. Because the threads of the upper threaded sleeve 27 and the lower threaded sleeve 28 are opposite in direction, they can drive the upper threaded sleeve 27 and the lower threaded sleeve 28 to rotate. The upper threaded sleeve 27 and the lower threaded sleeve 28 move in opposite directions. When installation is required, the upper threaded sleeve 27 and the lower threaded sleeve 28 need to move in opposite directions, thereby releasing the upper threaded sleeve 27 from the thrust on the upper inclined ring 25, thereby releasing the upper inclined ring 25 from the compression on the upper push rod 217, releasing the lower threaded sleeve 28 from the thrust on the lower inclined ring 26, thereby releasing the lower inclined ring 26 from the compression on the lower push rod 218. The connecting spring 216 begins to rebound, driving the fixing plate 214 and multiple sets of locking rods 219 to move synchronously towards the inside of the fixing cylinder 21. The locking rods 219 pass through the slide groove 22 and engage with the locking groove 24 on the surface of the insertion rod 23, thereby fixing the position of the insertion rod 23. The four sets of insertion rods 23 are locked in sequence to realize the installation and connection of the two-layer cultivation box 11. When it is necessary to disassemble the incubation box 11, the operator needs to rotate the upper rotating ring 211 or the lower rotating ring 212 in the opposite direction, causing the upper threaded sleeve 27 and the lower threaded sleeve 28 to rotate in opposite directions and begin to move towards each other. The upper threaded sleeve 27 pushes the upper inclined ring 25 through the upper thrust bearing 29, and the upper inclined ring 25 moves downward to begin to compress the upper push rod 217. The lower threaded sleeve 28 pushes the lower inclined ring 26 through the lower thrust bearing 210, and the lower inclined ring 26 moves upward to begin to compress the lower push rod 218. When the 7th and the lower push rod 218 are pressed, the fixing plate 214 moves to the outside of the fixing cylinder 21. The fixing plate 214 also moves the locking rod 219 to the outside of the fixing cylinder 21, thereby releasing the locking rod 219 and the vertical rod 220 from the locking groove 24. At this time, the connecting spring 216 is stretched, and then the insertion rod 23 can be pulled out from the fixing cylinder 21. By releasing the locking state of the four sets of insertion rods 23 in sequence, one layer of the cultivation box 11 can be removed, thus realizing the quick assembly and disassembly of the cultivation box 11.
