Description

Technical Field

[0001] This utility model relates to the field of germination technology, specifically to a device for the mass germination of paulownia seed roots. Background Technology

[0002] Paulownia is an important fast-growing timber and ecological protection tree species in my country. Its seedling cultivation technology is crucial to the development of the industry. Root budding is the core link in Paulownia seedling cultivation. The budding efficiency and budding quality directly determine the survival rate and growth performance of subsequent seedlings. Therefore, efficient batch budding devices are the key support for large-scale seedling cultivation. Studies have shown that the "micro-vibration" phenomenon in the soil in the natural environment, such as wind and rain disturbance and low-frequency vibration caused by animal activities, can significantly stimulate the activity of plant root cells. By promoting cell division in the root tip meristem and increasing enzyme activity, it accelerates the conversion of nutrients, thereby shortening the budding cycle and improving the uniformity of budding.

[0003] However, existing germination devices are mainly static germination modes and generally lack an active mechanism to stimulate the physiological activity of seed roots, making it difficult to meet the efficiency requirements of large-scale seedling cultivation. Therefore, it is necessary to design a device for batch germination of paulownia seed roots to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for the mass germination of paulownia seed roots, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for batch germination of paulownia seed roots, comprising: The incubator has multiple sets of sliding supports installed at equal intervals in its inner cavity. Each set of supports is pluggable to a set of germination trays, and each set of supports has a set of elastic elements detachably connected to one side. Each set of elastic elements is slidably and sealed to the side wall of the incubator. An eccentric cam assembly, with corresponding sets of elastic elements disposed on the outside of the incubator, is connected to the drive assembly for transmission, and the eccentric cam assembly can be adjusted in position along a preset direction to control its engagement and disengagement with the corresponding elastic elements. When the drive component is running, it can drive the eccentric cam component to rotate synchronously. When the eccentric cam component is connected to the elastic element, it drives the elastic element to reciprocate through the cam profile, thereby driving the support and germination tray to vibrate at low frequency. By selectively adjusting the engagement and disengagement state of each eccentric cam component and the corresponding elastic element, the synchronous vibration or individual vibration control of each germination tray can be achieved.

[0006] Preferably, the elastic element includes a T-shaped cylindrical member threadedly connected to one side of the support, the T-shaped cylindrical member being in a sealing sliding fit with the side wall of the incubator, the end of which is away from the support being able to abut against the eccentric cam assembly, and a spring being sleeved on the outside of the T-shaped cylindrical member.

[0007] Preferably, the eccentric cam assembly includes an eccentric cam body that can abut against one end of a T-shaped cylindrical member. A connecting shaft is installed at one end of the eccentric cam body, and a locking seat is fixedly installed at the other end of the connecting shaft. A locking bolt is threaded onto the locking seat, and a detachable locking engagement can be achieved with the drive assembly through the locking bolt.

[0008] Preferably, the drive assembly includes a rotating rod, on which a suitable mounting groove is provided for the connecting shaft and locking seat of each set of eccentric cam assemblies. The rotating rod is rotatably connected to the protective component installed on the outer wall of the incubator, and one end of the rotating rod is drively connected to the output end of the drive motor.

[0009] Preferably, the protective component includes a protective shell fixedly installed on the outer wall of the incubator, and a first magnetic door hinged to the protective shell.

[0010] Preferably, the inner cavity of the incubator is equipped with a detachable water receiving tray located below each group of germination trays. The inner cavity of the incubator is integrally formed with a guide rail corresponding to the position of each group of water receiving trays. The water receiving tray can slide along the guide rail to achieve quick assembly and disassembly.

[0011] Preferably, the incubator is also equipped with a temperature control module and a water supply module, which work together to provide a suitable temperature environment and water supply for the cultured objects in each group of germination trays.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a drive component to rotate an eccentric cam assembly. The eccentric cam profile periodically pushes an elastic element, causing the support and germination tray to vibrate at low frequency. This solves the problem of existing static germination devices lacking an active mechanism to stimulate the physiological activity of seed roots. The low-frequency vibration simulates the "micro-vibration" of natural soil to stimulate the activity of seed root cells, promote respiration and metabolism, and at the same time ensure that the seed roots are in uniform contact with water and nutrients, accelerating the germination process. It avoids continuous vibration from damaging the seed roots, improves the efficiency of batch germination, and is suitable for large-scale seedling cultivation requirements.

[0013] This invention uses an eccentric cam assembly to slide along the rotating rod for adjustment, and locks the rotating rod with a locking bolt to control its engagement and disengagement with the elastic element. This solves the problem that existing devices are difficult to adapt to large-scale seedling production efficiency and differentiated needs. It can quickly switch the "vibration / static" state of each group of germination trays, supports synchronous vibration to adapt to the same batch and variety of seed roots, and individual vibration to adapt to different batches or varieties of seed roots, thus improving the applicability of the device.

[0014] This invention features guide rails positioned below each germination tray within the incubator's inner cavity, with detachable water trays mounted on the rails. The incubator is equipped with a temperature control module and a water replenishment module that work together to effectively collect excess water from the germination trays, preventing water accumulation from affecting the germination environment. Furthermore, the water trays slide along the rails for quick assembly and disassembly, facilitating cleaning and maintenance. Attached Figure Description

[0017] 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.

[0018] Example 1 Please refer to Figures 1-5As shown, this utility model provides a device for mass germination of paulownia seed roots, comprising: a culture box 11, wherein multiple sets of slidable supports 12 are equidistantly installed in its inner cavity, each set of supports 12 is pluggably connected to a set of germination trays 13, and a set of elastic elements 10 is detachably connected to one side of each set of supports 12, and each set of elastic elements 10 is slidably and sealingly connected to the side wall of the culture box 11; an eccentric cam assembly 20, which is disposed on the outside of the culture box 11 corresponding to each set of elastic elements 10, and the eccentric cam assembly 20 is connected to a drive assembly 30 for transmission, and the eccentric cam assembly... The position of component 20 can be adjusted along a preset direction to control its engagement / disengagement state with the corresponding elastic component 10; when the drive component 30 is running, it can drive the eccentric cam component 20 to rotate synchronously. When the eccentric cam component 20 is connected to the elastic component 10, it pushes the elastic component 10 to reciprocate through the cam profile, thereby driving the support 12 and the germination tray 13 to vibrate at low frequency; by selectively adjusting the engagement / disengagement state of each set of eccentric cam components 20 with the corresponding elastic component 10, the synchronous vibration or individual vibration control of each set of germination trays 13 can be achieved.

[0019] The paulownia seed roots awaiting budding are placed in the germination tray 13, and the germination tray 13 is installed on the sliding bracket 12 inside the incubator 11 by insertion and removal, completing the deployment of the paulownia seed roots. The elastic element 10 on one side of the bracket 12 is slidably connected to the side wall of the incubator 11, ensuring the airtightness of the incubator cavity while providing an elastic reset basis for vibration. According to the germination requirements, the positions of each set of eccentric cam assemblies 20 are adjusted in a preset direction. If a certain set of germination trays needs to vibrate, the corresponding eccentric cam assembly 20 is made to contact and connect with the elastic element 10; if vibration is not required, the two are separated, achieving selective vibration of single or multiple sets. The control system activates the drive assembly 30, which drives all eccentric cam assemblies 20 to rotate synchronously. The eccentric cam assemblies 20 in the connected state periodically drive the elastic element 10 to reciprocate through the eccentric structure of the cam profile. The elastic element 10 drives the support 12 and the germination tray 13 to vibrate synchronously at low frequency. The elastic characteristics of the elastic element, combined with the cam profile, make the vibration frequency stable and controllable. By uniformly adjusting all eccentric cam assemblies 20 and corresponding elastic elements 10 to be in the connected state, the synchronous vibration of each group of germination trays 13 can be achieved. By individually adjusting a few groups to be in the connected state and the rest to be in the disconnected state, the individual vibration of a specified group of germination trays can be achieved.

[0020] The elastic element 10 is sealed and slidably connected to the side wall of the incubator 11 to prevent leakage of temperature and humidity inside the incubator during vibration, providing a stable environmental foundation for the germination of paulownia seed roots. It supports the synchronous vibration of multiple germination trays and is suitable for paulownia seed roots of the same batch and variety as well as for individual vibration and independent operation of a single group. It adapts to the differentiated germination needs of paulownia seed roots of different batches or varieties, improving the applicability of the device. Low-frequency vibration can simulate the "micro-vibration" of soil in the natural environment, such as wind and rain, or animal activity, to stimulate the activity of seed root cells and promote germination. It can be used with the vibration timer in the existing technology to vibrate 1-2 times a day for 5-10 minutes each time, avoiding continuous vibration damage to the seed roots. Low-frequency vibration ensures that the paulownia seed roots in the germination tray 13 are in uniform contact with water and nutrients, while enhancing the respiration and metabolic activity of the paulownia seed roots and accelerating the germination process.

[0021] Specifically, the elastic element 10 includes a T-shaped cylindrical element 101 that is threaded to one side of the support 12. The T-shaped cylindrical element 101 is in a sealing sliding fit with the side wall of the incubator 11. The end of the T-shaped cylindrical element 101 that is away from the support 12 can abut against the eccentric cam assembly 20. A spring 102 is sleeved on the outside of the T-shaped cylindrical element 101.

[0022] The eccentric cam assembly 20 includes an eccentric cam body 201 that can abut against one end of the T-shaped cylindrical member 101. A connecting shaft 202 is installed at one end of the eccentric cam body 201, and a locking seat 203 is fixedly installed at the other end of the connecting shaft 202. A locking bolt 204 is threaded onto the locking seat 203, and a detachable locking engagement can be achieved with the drive assembly 30 through the locking bolt 204.

[0023] The drive assembly 30 includes a rotating rod 301. The rotating rod 301 has a matching mounting groove corresponding to the connecting shaft 202 and locking seat 203 of each eccentric cam assembly 20. The rotating rod 301 is rotatably connected to the protective part 40 installed on the outer wall of the incubator 11, and one end of the rotating rod 301 is connected to the output end of the drive motor 302.

[0024] The protective component 40 includes a protective shell 401 fixedly installed on the outer wall of the incubator 11, and a first magnetic door 402 hinged to the protective shell 401.

[0025] First, the seeds to be germinated are evenly placed in each germination tray 13. The germination trays 13 are then installed on the sliding brackets 12 inside the incubator 11 by plugging and unplugging, completing the seed carrying deployment. According to the seed germination requirements, the first magnetic door 402 is opened. The first magnetic door 402 is equipped with a transparent window and has the same sealing principle as the incubator 11. Then, the positions of each group of eccentric cam assemblies 20 are adjusted: if a certain group of germination trays 13 needs to vibrate individually, the other eccentric cam assemblies 20 are slid along the rotating rod 301 to disengage the eccentric cam body 201 from the corresponding T-shaped cylindrical part 101. Then, the locking bolt 204 is rotated to make the locking bolt 204 fit tightly with the mounting groove of the rotating rod 301, thereby locking the position of the eccentric cam assembly 20. At this time, only that group is in the "connected state". If a certain group needs to vibrate, it is connected to the corresponding T-shaped cylindrical part 101.

[0026] Then, the drive motor 302 is started. The output torque of the drive motor 302 drives the rotating rod 301 to rotate at a constant speed around its own axis. The rotating rod 301 synchronously drives all the eccentric cam assemblies 20 in the "connected state" to rotate. Since the eccentric cam body 201 is an eccentric structure, during its rotation, the outer peripheral contour will periodically generate a thrust on the force-bearing end of the T-shaped cylindrical part 101: when the distal end of the cam contour pushes towards the T-shaped cylindrical part 101, the T-shaped cylindrical part 101 slides axially towards the inner cavity of the incubator 11, driving the support 12 and the germination tray 13 to move synchronously. At this time, the spring 102 is compressed; when the proximal end of the cam contour turns towards the T-shaped cylindrical part 101, the restoring force of the spring 102 pushes the T-shaped cylindrical part 101 to slide in the opposite direction, driving the support 12 and the germination tray 13 to return to the initial position. Through the continuous rotation of the eccentric cam body 201 and the restoring action of the spring 102, the support 12 and the germination tray 13 achieve stable low-frequency reciprocating vibration.

[0027] Based on the structural design of the eccentric cam assembly 20 sliding along the rotating rod 301 and locked by the locking bolt 204, the "vibration / static" state switching of each group of germination trays 13 can be quickly realized. It supports both synchronous vibration and individual vibration modes, greatly improving the device's adaptability to diverse germination needs. The germination trays 13 adopt plug-in installation, and the bracket 12 has a sliding design, which facilitates seed loading and unloading and cleaning of the germination trays. The magnetic design of the first magnetic door 402 enables quick opening and closing. Combined with the sliding adjustment of the eccentric cam assembly 20 and the convenient locking of the locking bolt 204, the clutch state adjustment operation is simple and efficient. The protective shell 401 encloses the moving parts, reduces foreign object interference, lowers the equipment failure rate, and prevents personnel from accidentally touching the moving parts, thus improving operational safety.

[0028] The incubator 11 has a detachable water tray 14 located below each group of germination trays 13. A guide rail 15 is integrally formed in the incubator 11 corresponding to the position of each water tray 14. The water tray 14 can slide along the guide rail 15 for quick assembly and disassembly. The water tray 14 is slid into its corresponding position along the guide rail 15 in the incubator 11, ensuring it is precisely positioned below each group of germination trays 13 to collect excess water. Based on the germination characteristics of paulownia seeds, the incubator 11 is also equipped with a temperature control module 16 and a water replenishment module 17. These two modules work together to provide a suitable temperature environment and water supply for the germination objects in each group of germination trays 13. The temperature control module 16 presets the target temperature, and the water replenishment module 17 sets the water replenishment cycle and the amount of water replenished at one time.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
