[0002] Soilless seedling cultivation is a new technology used in modern plant cultivation. It does not use soil, but mixes the nutrients needed by plants into culture solution to cultivate plants. The advantages of soilless seedling cultivation are rapid growth of seedlings, short seedling age, good root development, strong and neat seedlings, short seedling acclimatization time after planting, and easy survival. Whether it is substrate seedling cultivation or nutrient solution seedling cultivation, it can ensure sufficient water and nutrient supply and good substrate ventilation. At the same time, soilless seedling cultivation is convenient for scientific and standardized management.

[0003] The shortcomings of the prior art are as follows: First, in order to ensure that there is sufficient oxygen in the nutrient solution, traditional soilless seedling raising equipment for forestry seedling raising usually uses an oxygen pump to oxygenate the nutrient solution, which is costly. Second, when using the soilless seedling raising equipment for forestry seedling raising, the nutrient solution needs to be replenished regularly, and the nutrient solution cannot be replenished when the concentration of the nutrient solution is low. Third, during the growth of the seedlings, it is necessary to ensure that the stems of the seedlings are straight, and the traditional soilless seedling raising equipment cannot adjust the height of the fixed frame of the seedlings according to the growth length of the seedlings.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0046] See also Figure 1 to Figure 8 In an embodiment of the present invention, a forestry soilless seedling raising equipment includes: a seedling raising box 1, an arc-shaped fixing member 3, an elastic trigger component, a reciprocating plate 19, a water inlet component and a water outlet component, and a linkage component, so that when the flow direction of the nutrient solution in the seedling raising box 1 changes, the swinging state of the two reciprocating plates 19 will be switched, so that the oxygen can form an impact effect with the nutrient solution after escaping from the air guide hole 1901, thereby increasing the oxygen content in the nutrient solution.

[0047] Specifically, the seedling box 1 is detachably provided with a support plate 2, the support plate 2 is provided with a plurality of through holes 201, the arc-shaped fixing members 3 are arranged in groups of two on the support plate 2, and the two arc-shaped fixing members 3 cooperate to support the plants;

[0048] The elastic trigger assembly connects the two arc-shaped fixing members 3 in the same group, and the elastic trigger assembly can drive the two arc-shaped fixing members 3 in the same group to move closer to or away from each other. The elastic trigger assembly includes an extension plate 4 integrally formed with the arc-shaped fixing member 3, and the extension plate 4 is formed with a slide groove 401 along its length direction, and the slide groove 401 is slidably connected to a fixing block 5 fixed on the supporting plate 2;

[0049] A transverse shaft 6 slidably connected to the fixed block 5 is also installed in the slide groove 401, and a spring 7 is sleeved on the transverse shaft 6. One end of the spring 7 is connected to the side wall of the slide groove 401, and the other end is connected to the fixed block 5;

[0050] The elastic trigger assembly also includes a two-way driving structure connected to the extension plate 4, and the two-way driving structure includes a fixed sleeve plate 9 fixedly installed on the supporting plate 2, a lifting plate 10 is slidably installed in the fixed sleeve plate 9, and a connecting rod 8 is rotatably installed on the lifting plate 10, and the end of the connecting rod 8 away from the lifting plate 10 is rotatably connected to the extension plate 4.

[0051] When in use, press the lifting plate 10, and the lifting plate 10 moves toward the supporting plate 2, and drives the extension plate 4 to slide relative to the fixed block 5 through the connecting rod 8, so that the No. 1 spring 7 is compressed, and the two arc-shaped fixing parts 3 in the same group will move away from each other. At this time, the plant to be cultivated is placed in the through hole 201, and then release the lifting plate 10. At this time, the No. 1 spring 7 will release elastic potential energy, and the two extension plates 4 will move closer to each other, so as to drive the two arc-shaped fixing parts 3 in the same group to move closer to each other, until the two arc-shaped fixing parts 3 are concentric with the through hole 201, and the two arc-shaped fixing parts 3 form a circular ring structure, which can support the plant and prevent the plant from falling over and affecting its growth.

[0052] Among them, a cylindrical cavity structure is arranged in the through hole 201, and small holes are formed on the bottom and circumferential side walls of the cylindrical cavity structure. The nutrient solution can enter the cylindrical cavity structure through these small holes and infiltrate the roots and stems of the plants to ensure their normal growth.

[0053] Through the above arrangement, the two arc-shaped fixing members 3 can be driven to move closer to or away from each other by pressing and releasing the lifting plate 10. When the two arc-shaped fixing members 3 move away from each other, the plant can be conveniently placed in the through hole 201. When the two arc-shaped fixing members 3 move closer to each other, a circular ring structure can be formed, thereby supporting the plant and preventing the plant from falling over.

[0054] See also Figure 4~Figure 6The reciprocating plates 19 are provided with two groups and are rotatably installed in the seedling box 1. The two groups of reciprocating plates 19 can alternately cooperate with the power components provided on the seedling box 1 to reciprocate and deflect. The interior of the reciprocating plates 19 is a hollow structure, and a plurality of air guide holes 1901 are formed on the reciprocating plates 19. An air inlet hole 1902 is also provided at one end of the rotating shaft of the reciprocating plates 19;

[0055] The power assembly includes a guide member 21 installed on the seedling box 1, and a follower sleeve 22 is slidably installed on the guide member 21 along its length direction. The interior of the follower sleeve 22 is a hollow structure, and a telescopic plate 23 is slidably sleeved in the follower sleeve 22. A driving device 11 is fixedly installed on the telescopic plate 23, and a driving gear 12 coaxial with the output shaft of the driving device 11 is provided. The driving gear 12 is adapted to a first driven gear 13 and a second driven gear 14 rotatably installed on the seedling box 1;

[0056] The first driven gear 13 and the second driven gear 14 are connected to the rotating shaft of the reciprocating plate 19 through a chimeric structure, and the chimeric structure includes a deflection rod 18 fixedly connected to the rotating shaft of the reciprocating plate 19, and the deflection rod 18 is provided with a hysteresis groove 15 along its length direction;

[0057] The interlocking structure includes a turntable 16 rotatably mounted on the seedling box 1 and connected to the first driven gear 13 or the second driven gear 14 through a first belt, and a convex shaft 17 is fixedly mounted at an eccentric position of the turntable 16, and the convex shaft 17 can slide along the length direction of the retardation groove 15;

[0058] The power assembly also includes an energy storage structure arranged between the follower sleeve 22 and the telescopic plate 23, and between the driving gear 12 and the seedling box 1, the energy storage structure includes a vertical shaft 24 fixedly connected to the follower sleeve 22, the vertical shaft 24 is slidably connected to the telescopic plate 23, and a No. 2 spring 25 is sleeved on the vertical shaft 24, one end of the No. 2 spring 25 is connected to the end of the vertical shaft 24, and the other end is connected to the telescopic plate 23;

[0059] The energy storage structure also includes a groove wheel set connecting the driving gear 12 and the seedling box 1, and an electric telescopic rod 20 is fixedly installed on the seedling box 1, and the action end of the electric telescopic rod 20 is connected to the follower sleeve plate 22;

[0060] The groove wheel kit includes an interlocking wheel 26 coaxially connected to the driving gear 12 and a side plate arranged on the side of the seedling box 1, and two inclined grooves 27 are symmetrically arranged on the side plate. The two inclined grooves 27 are connected by a horizontal groove 28, and the interlocking wheel 26 can switch between the two inclined grooves 27 via the horizontal groove 28.

[0061] In the initial state, the engaging wheel 26 is at the end of one of the inclined grooves 27. At this time, under the action of the second spring 25, the engaging wheel 26 has a tendency to maintain the existing state, so that the driving gear 12 can be stably meshed with the first driven gear 13 or the second driven gear 14, thereby driving one of the reciprocating plates 19 to deflect;

[0062] When the electric telescopic rod 20 moves, it can drive the follower sleeve 22 to move along the length direction of the guide member 21. At this time, the engaging wheel 26 will move along the inclined groove 27 and separate from the first driven gear 13 or the second driven gear 14. As the follower sleeve 22 continues to move, the engaging wheel 26 will move along the length direction of the horizontal groove 28 to the other inclined groove 27, and enable the driving gear 12 to mesh with the second driven gear 14 or the first driven gear 13, thereby driving the other reciprocating plate 19 to swing.

[0063] Among them, the arrangement of the second spring 25, the inclined groove 27 and the engaging wheel 26 can ensure that after the driving action is completed, even if the electric telescopic rod 20 is powered off, the driving gear 12 can still maintain a stable meshing relationship with the first driven gear 13 or the second driven gear 14.

[0064] When the first driven gear 13 or the second driven gear 14 rotates, the turntable 16 connected thereto will be driven to rotate, and the cam 17 will make a circular motion. The cam 17 cooperates with the hysteresis groove 15, and when the cam 17 makes a circular motion, the reciprocating plate 19 will be driven to deflect.

[0065] The oxygen pumping device is connected to the air inlet 1902 through a pipeline, and during the deflection of the reciprocating plate 19, oxygen escapes from the air guide hole 1901 and mixes with the nutrient solution to increase the oxygen content in the nutrient solution.

[0066] Through the above arrangement, during the movement of the electric telescopic rod 20, the driving gear 12 can alternately mesh with the first driven gear 13 and the second driven gear 14 to respectively drive the two reciprocating plates 19 to swing, thereby increasing the turbulence of oxygen in the nutrient solution and improving the oxygen content in the nutrient solution.

[0067] See also Figure 1 , Figure 7 , Figure 8 The water inlet assembly and the water outlet assembly are connected to the seedling box 1, and the water inlet assembly cooperates with the water outlet assembly to change the flow direction of the nutrient solution in the seedling box 1, and the water inlet assembly cooperates with the water outlet assembly to be connected through a No. 3 belt;

[0068] The water inlet assembly includes a diverter 32 fixedly connected to the seedling box 1, the interior of the diverter 32 is a hollow structure, and the diverter 32 is connected to the two sides of the seedling box 1 through two vertically arranged conduits 33. Specifically, the structure of the water outlet assembly is exactly the same as that of the water inlet assembly;

[0069] A switching member 31 is installed in the flow dividing member 32 and is sealingly and slidably connected to the inner wall thereof. The switching member 31 is connected to the linkage assembly, and a through hole 3101 is formed on the switching member 31.

[0070] The linkage assembly connects the water inlet assembly, the water outlet assembly and the power assembly, and the linkage assembly enables the reciprocating plate 19 in the direction of nutrient solution flow to cooperate with the power assembly, and the linkage assembly includes a follower shaft 29 fixedly connected to the follower sleeve 22, and the follower shaft 29 is sleeved with a rotating sleeve 30 rotatably connected to the seedling box 1, and the rotating sleeve 30 is connected to the rotating shaft of the switching member 31 through a No. 2 belt;

[0071] A spiral groove 3001 is formed in the rotating sleeve 30 , and the protrusion 2901 disposed on the follower shaft 29 can slide in the spiral groove 3001 .

[0072] In this embodiment, two conduits 33 are respectively provided on both sides of the seedling box 1, and one of the two conduits 33 is responsible for water inlet and the other for water outlet. When water enters a conduit 33 on one side of the seedling box 1, the other conduit 33 on the side closes the water outlet, and the conduit 33 on the other side discharges water, and the conduit 33 on the side closes the water outlet. Specifically:

[0073] When the electric telescopic rod 20 drives the driving gear 12 to move, the follower shaft 29 will also move, and under the cooperation of the protrusion 2901 and the spiral groove 3001, the rotating sleeve 30 will rotate, and drive the switching member 31 to rotate through the No. 2 belt to change the flow direction of the nutrient solution in the seedling box 1.

[0074] For ease of understanding, the two sides of the seedling box 1 are named a and b respectively. When the flow direction of the nutrient solution is from a to b, the reciprocating plate 19 close to the b side will swing back and forth. At this time, when the oxygen escapes from the air guide hole 1901, it can form an impact effect with the nutrient solution, thereby increasing the oxygen content in the nutrient solution. When the flow direction of the nutrient solution is from b to a, the reciprocating plate 19 close to the a side will swing, that is, the swing of the reciprocating plate 19 always matches the flow direction of the nutrient solution.

[0075] Through the above arrangement, when the flow direction of the nutrient solution in the seedling box 1 changes, the swinging state of the two reciprocating plates 19 will switch, so that the oxygen escaping from the air guide hole 1901 can impact the nutrient solution and increase the oxygen content in the nutrient solution.
