[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, many other embodiments obtained by those of ordinary skill in the art without creative effort are all within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, this invention provides a greenhouse germination machine for propagating Liquidambar formosana seeds, including a frame 1 and two conveyor belts 2 symmetrically arranged on both sides of the inner wall of the frame 1. Support plates 3 for carrying cotton gauze are placed on the two conveyor belts 2, with mesh 31 inside the support plates 3 and several layers of cotton gauze placed on them. Fixing mechanisms 4 for securing the cotton gauze are provided on both sides of the frame 1. A liquid storage tank 5 is provided inside the frame 1, located at the bottom end of the two conveyor belts 2. A spraying mechanism 6 for spraying nutrient solution onto the cotton gauze is provided on the liquid storage tank 5. A spreading mechanism 7 for spreading seeds onto the cotton gauze is provided on the frame 1. A cultivation box 8 is provided at the tail end of the frame 1, with a feed inlet 81 on the side wall of the cultivation box 8 facing the frame 1. The tail ends of both conveyor belts 2 are connected to the inner bottom wall of the feed inlet 81.

[0033] In use, the present invention places the cotton gauze on the support plate 3 using a folding mechanism that can fold the cotton gauze. Then, the support plate 3 is transported or placed on the two conveyor belts 2 at the top of the frame 1 by a conventional transmission component or robotic arm. Since the above-mentioned equipment is conventional, it will not be described in detail here. The support plate 3 is then transported to the bottom of the two fixing mechanisms 4 by the two conveyor belts 2. The two fixing mechanisms 4 fix the support plate 3 and the cotton gauze placed on the top of the support plate 3. Then, during the transport process, the support plate 3 passes over the spraying mechanism 6. The spraying mechanism 6 sprays nutrient solution onto the support plate 3, and after being filtered by the mesh 31, it is sprayed onto the cotton gauze until the cotton gauze is completely wetted. The mesh 31 is designed to prevent water pressure from directly impacting the cotton gauze, thereby preventing the cotton gauze from bulging and becoming uneven, and thus avoiding affecting the subsequent placement of seeds, etc.

[0034] After being moistened with nutrient solution, the cotton gauze is conveyed by conveyor belt 2 to the area directly below the spreading mechanism 7. The spreading mechanism 7 quickly and evenly spreads the seeds onto the cotton gauze. Then, the carrying plate 3 is conveyed from the inlet 81 into the incubation box 8. When several carrying plates 3 have sequentially fed the seeds into the incubation box 8 and the incubation box 8 is filled with seeds, the inlet 81 is closed. Then, the temperature control component in the incubation box 8 is turned on to maintain the temperature in the incubation box 8 at 18-21°C until the germinated seeds sprout. Before the carrying plate 3 enters the incubation box 8, the fixing mechanism 4 loosens the fixing of the carrying plate 3. If necessary, the cotton gauze can be placed on the carrying plate 3 again before the carrying plate 3 enters the incubation box 8. In this invention, the cotton gauze is fixed and then passed through the spraying mechanism 6 and the spreading mechanism 7 in sequence to complete the preparation work before seed cultivation. This is efficient and fast, greatly improving the work effect, reducing the workload and cost. Furthermore, the fixing mechanism 4 prevents the cotton gauze from wrinkling during the subsequent wetting and spreading process, avoiding unevenness and thus improving the cultivation effect. The spraying mechanism 6 is located at the bottom of the support plate 3 and sprays to avoid the impact of the nutrient solution during the spraying process, which could cause the cotton gauze to shift or dent, further improving the flatness of the cotton gauze.

[0035] The fixing mechanism 4 includes a side plate 41, a fixing component 42 for fixing the bearing plate 3, and a driving component 43 for resetting the fixing component 42. The side plate 41 is fixedly installed on the inner side wall of the frame 1. A sliding groove 44 is opened inside the side plate 41. A sliding rod 45 is fixedly connected inside the sliding groove 44. A slider 46 is slidably connected inside the sliding groove 44. The slider 46 passes through the sliding rod 45 and is slidably connected to the sliding rod 45. The fixing component 42 is fixed to the bottom of the slider 46. The driving component 43 is fixedly installed on the frame 1, and the output end of the driving component 43 is fixedly connected to the slider 46.

[0036] Furthermore, the fixing assembly 42 includes a fixing plate 421, a pressing plate 422, and two electric push rods 423. The fixing plate 421 is fixedly disposed at the bottom of the slider 46, and the two electric push rods 423 are both fixedly disposed at the bottom of the fixing plate 421. The pressing plate 422 is fixedly disposed at the output end of the two electric push rods 423.

[0037] An infrared sensor 10 is installed on the side wall of the frame 1 near the fixed component 42, and a position switch 11 is installed on the side wall of the frame 1 near the incubator 8. Both the infrared sensor 10 and the position switch 11 are electrically connected to the drive component 43 and the two electric push rods 423.

[0038] When the conveyor belt 2 moves the carrier plate 3 directly below the two fixed mechanisms 4, the infrared sensor 10 on one side of the fixed assembly 42 first senses the position of the carrier plate 3, and then sends a signal to the processor, causing the processor to control the output ends of the two electric push rods 423 to move downward, thereby driving the extrusion plate 422 to move down to contact the cotton yarn, until the extrusion plate 422 tightly presses the cotton yarn against the carrier plate 3. As the conveyor belt 2 moves, the carrier plate 3 moves synchronously, thereby driving the extrusion plate 422 above it to move, so that the slider 46 fixed to the fixed plate 421 moves along the slide groove 44 and the slide rod 45. At the same time, the drive assembly 43 includes a motor, a rotating roller and a steel wire rope. The output shaft of the motor is fixedly connected to the rotating roller, the steel wire rope is wound around the rotating roller, and the other end of the steel wire rope is fixedly connected to the slider 46. The motor drives the slider 46 to move along the slide groove 44 and the slide rod 45. The rotating roller rotates, unwinding the steel wire rope on it. As the slider 46 moves, it pulls one end of the steel wire rope. When the bearing plate 3 moves to the end of the conveyor belt 2, it presses the position change switch 11, thereby resetting the two electric push rods 423. This causes the output end of the electric push rods 423 to move the pressing plate 422 upward, releasing the fixing effect on the bearing plate 3. Subsequently, the motor drives the rotating roller to rotate in the opposite direction, winding the steel wire rope and pulling the slider 46 back to its initial position. Through the setting of the fixing mechanism 4, the cotton gauze on the moving bearing plate 3 can always be fixed, ensuring that the cotton gauze is always clamped on the bearing plate 3 for subsequent processes. The fixing effect is good, and it can automatically reset. It is flexible in use and effectively avoids wrinkles or displacement of the cotton gauze, greatly improving the quality of seed cultivation.

[0039] The spraying mechanism 6 includes a filter screen 61, multiple crossbars 62, and multiple nozzles 63. The filter screen 61 is hung inside the liquid storage tank 5. The multiple crossbars 62 are evenly fixed on the top of the filter screen 61. The multiple nozzles 63 are evenly arranged on the multiple crossbars 62. A water storage tank 64 is opened inside the crossbars 62. The input ends of the multiple nozzles 63 are all connected to the water storage tank 64. A water guide pipe 65 is connected to the bottom of the water storage tank 64. The water guide pipe 65 extends into the interior of the filter screen 61. A water pump 66 is connected to the bottom of the multiple water guide pipes 65.

[0040] When the support plate 3 moves above the nozzle 63, the water pump 66 transports the nutrient solution inside the storage tank 5 to the water guide pipe 65, thereby allowing the water guide pipe 65 to transport the nutrient solution to the storage tank 64. The nutrient solution inside the storage tank 64 is then evenly sprayed onto the bottom of the support plate 3 through the nozzle 63, so that the nutrient solution completely wets the cotton gauze. During the spraying process, excess nutrient solution can fall into the filter screen 61. The multiple crossbars 62 and the nozzles 63 above them can accelerate the spraying effect of the nutrient solution, making the cotton gauze wet faster.

[0041] A water baffle 9 is also installed on the frame 1, located directly above the filter screen 61. The water baffle 9 prevents the nutrient solution from splashing too widely and affecting the operation of other equipment.

[0042] The feeding mechanism 7 includes a fixed frame 71, a storage cylinder 72, a rotating rod 73, a sealing plate 79, multiple push plates 74, and a motor. The fixed frame 71 is fixedly installed on the top of the frame 1. The storage cylinder 72 is fixed inside the fixed frame 71. The rotating rod 73 is rotatably installed at the central axis of the storage cylinder 72. Multiple discharge holes 76 are opened on the bottom wall of the storage cylinder 72. The sealing plate 79 is fixedly sleeved on the rotating rod 73, and two guide ports 77 are symmetrically opened inside the sealing plate 79. Valves are installed inside the guide ports 77. A sleeve shaft 78 is fixedly connected to the bottom of the sealing plate 79. Multiple push plates 74 are evenly arranged on the outer wall of the sleeve shaft 78 along the circumferential direction. Each push plate 74 has a slot, and a filter screen 741 is fixedly connected inside each slot. The motor is fixedly installed on the top of the storage cylinder 72, and the motor output end is fixedly connected to the top of the rotating rod 73. A feed pipe is provided on the top of the storage cylinder 72.

[0043] When the support plate 3 enters directly below the spreading mechanism 7, the valve in the guide port 77 opens, allowing the seeds above the sealing plate 79 to fall into the discharge hole 76 and then onto the cotton gauze on the support plate 3. To prevent seeds from accumulating at the bottom of the storage cylinder 72, the motor drives the rotating rod 73 to rotate, causing the sealing plate 79 and the sleeve shaft 78 to rotate synchronously, accelerating the flow rate of seeds on the sealing plate 79. Simultaneously, when the sleeve shaft 78 rotates, it drives multiple push rods 423 to rotate, pushing the seeds at the bottom of the storage cylinder 72 into the discharge hole 76. Larger seeds that cannot be discharged from the discharge hole 76 remain in the storage cylinder 72 for screening. When there are many seeds between the two push plates 74, especially smaller seeds, they can be dispersed through the filter screen 741 into the remaining discharge holes 76, thus diverting the seeds.

[0044] Furthermore, each of the multiple push plates 74 has a brush 75 fixedly connected to its bottom. The bottom of each brush 75 is in contact with the bottom wall of the storage cylinder 72. The rotation of the multiple push plates 74 drives the brush 75 at its bottom to rotate, thereby cleaning the bottom of the storage cylinder 72 and pushing the seeds in the multiple discharge holes 76 to prevent the seeds from clogging the discharge holes 76.

[0045] The seed spreading mechanism 7 can screen the seeds and spread them evenly, which can better ensure uniform germination and rooting, reduce seed waste, avoid localized over-seeding, and ensure seed growth.

[0046] The incubator 8 is equipped with a shelf 82 inside, and multiple storage frames 83 are evenly arranged inside the shelf 82 along its height direction. The bottom of the incubator 8 is equipped with a lifting mechanism 85, and the output end of the lifting mechanism 85 is fixedly connected to the bottom of the shelf 82.

[0047] When the carrier plate 3 moves to the end of the conveyor belt 2, it can enter the storage frame 83 inside the storage rack 82 through the feed inlet 81. Then, the lifting mechanism 85 drives the storage rack 82 to move down, moving the empty storage frame 83 down so that the next carrier plate 3 can enter, achieving the effect of batch seed cultivation. Moreover, the lifting is automatic, eliminating the need for manual handling, reducing labor intensity and costs.

[0048] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
