Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, specifically to a plant seedling cultivation device. Background Technology

[0002] Seedling cultivation refers to the process of nurturing seedlings in nurseries, hotbeds, or greenhouses for transplanting into the ground. It can also refer to the stage in which various microorganisms, after being artificially protected, grow to the point where they can survive independently. In current plant seedling cultivation, different varieties of the same plant species (such as rice) may exist. During cultivation, different varieties of plants need to be placed separately to facilitate comparative analysis of their growth later. However, since existing cultivation devices are usually individual cultivation trays placed separately, the varying locations during cultivation can lead to differences in light, rainwater, or sprinkler intake, resulting in different growth rates or survival rates for different varieties of seedlings. This, in turn, affects the later data and comparative analysis of different varieties of plant seedlings.

[0003] A search revealed a Chinese patent publication number CN220915930U, which discloses a plant seedling cultivation device. In this patent, a transmission mechanism set inside the cultivation box can drive different cultivation trays to move inside, thereby facilitating uniform spraying, allowing different plant varieties to grow in the same environment, and facilitating subsequent data statistics and comparative analysis. At the same time, by setting the shape of the cultivation trays and the placement tray, it can be ensured that the cultivation trays remain horizontal when moving with the transmission structure, preventing them from tipping over and causing the plant varieties to fall out. It also makes it easy for staff to remove the placement trays.

[0004] However, when the above-mentioned device is used, the bottom of the cultivation tray structure is sealed, making it difficult to replace the sprayed nutrient solution, which may affect the growth of the plant seedlings. At the same time, when the water or nutrient solution falls straight down into the inner cavity of the water receiving tray, the water is easy to splash onto the inner wall of the cultivation box, causing pollution to the cultivation box and thus affecting the growth of the plant seedlings inside the cultivation box. Utility Model Content

[0005] This invention proposes a plant seedling cultivation device that can automatically replace the nutrient solution inside the cultivation tray, thereby improving the growth efficiency of the plant seedlings and preventing the discharged nutrient solution from splashing into the cultivation chamber and causing contamination, which would affect the normal growth of the plant seedlings. It solves the problems of not being able to automatically replace the nutrient solution inside the cultivation tray, thus affecting the growth efficiency of the plant seedlings inside the cultivation tray, and the problem of the discharged nutrient solution splashing onto the inner wall of the cultivation chamber, causing contamination and affecting the normal growth of the plant seedlings.

[0006] The technical solution of this utility model is as follows: A plant seedling cultivation device includes a frame. A circulating belt is detachably installed in the middle of the inner cavity of the frame. Multiple mounting blocks are fixedly installed on both the left and right sides of the outer surface of the circulating belt. A spring is fixedly installed on the side of the mounting block near the left and right side walls of the frame. A pull ring is fixedly installed on the other side of the spring. A locking block is fixedly installed on the side of the pull ring away from the frame. An insertion rod can be installed on the front side of the mounting block. The insertion rod extends into the inner cavity of the mounting block and has a locking hole on the side facing the spring. A cultivation frame is movably installed on the front side of the insertion rod. A discharge port is opened on the left side of the bottom of the cultivation frame. A first torsion shaft is rotatably installed on the left side of the bottom of the cultivation frame. A first horizontal plate is fixedly installed at the bottom of the first torsion shaft. A sealing block is fixedly installed on the right side of the top of the first horizontal plate. A first Velcro fastener is fixedly installed on the left side of the bottom of the first horizontal plate. A second torsion shaft is rotatably installed at the bottom of the left side of the inner cavity of the frame. A second horizontal plate is fixedly installed at the bottom of the second torsion shaft. A second Velcro fastener is fixedly installed on the right side of the top of the second horizontal plate.

[0007] Preferably, a water pump is fixedly installed on the top of the frame, a water spray block is detachably installed on the bottom of the water pump, a side plate is rotatably installed on the front side of the frame via a hinge, a collection frame is detachably installed on the bottom of the frame, an installation frame is detachably installed on the top of the inner cavity of the collection frame, and a sponge block is fixedly installed in the middle of the installation frame.

[0008] Preferably, motors can be detachably installed on the top left side and the bottom right side of the frame. Rollers can be detachably installed on the side of the motor that extends into the inner cavity of the frame. The circulating belt is wound around the outer surface of the upper and lower rollers. In use, the motors on the left and right sides are of the same model and power, so as to control the upper and lower rollers to rotate forward and counterclockwise at the same time. At the same time, the output power of the motor can be controlled by different buttons on the surface of the motor, thereby controlling the rotation speed of the rollers connected to the output shaft, that is, controlling the rotation speed of the circulating belt.

[0009] Preferably, the pull ring is connected to the left side of the mounting block by a spring. The shape and length of the cross-section of the locking block are matched with the bottom length and cross-sectional shape of the locking hole cavity opened on one side of the pull ring facing the side of the inserted rod after installation. Thus, when in use, after the inserted rod is inserted into the cavity of the mounting block, the pull ring and the locking block are used to fix the inserted rod installed on the outer surface of the circulation belt in the cavity of the mounting block.

[0010] Preferably, the shape and installation position of the sealing block are matched with the cross-sectional shape and opening position of the inner cavity of the discharge port. The first horizontal plate is rotatably installed on the left side of the bottom of the culture frame via the first torsion shaft. Thus, under normal circumstances, the first horizontal plate is always in a horizontal state under the elastic force of the torsion spring in the inner cavity of the first torsion shaft. At this time, the sealing block is installed in the inner cavity of the discharge port to seal the culture frame and prevent the nutrient solution in the inner cavity of the culture frame from leaking.

[0011] Preferably, the position of the second horizontal plate matches the position of the first horizontal plate at the bottom of the rear culture frame of the circulation belt, and the shape and position of the first and second Velcro fasteners match. Thus, when the culture frame at the rear of the circulation belt rotates from back to front during use, the bottommost culture frame at the rear moves down, causing one side of the first horizontal plate at the bottom of the bottommost culture frame at the rear to overlap and contact one side of the second horizontal plate. That is, the first and second Velcro fasteners are used to bond together, thereby increasing the contact time between the first and second horizontal plates, that is, increasing the time for the sealing block to leave the inner cavity of the discharge port, facilitating the leakage of nutrient solution from the inner cavity of the culture frame.

[0012] Preferably, the bottom of the water spray block has multiple spray nozzles, the water spray block is set at the top of the inner cavity of the frame, and the water spray block is located directly above the rear culture frame. The shape of the bottom surface of the water spray block is smaller than the shape of the cross-section of the inner cavity of the rear culture frame. One side of the water pump is connected to the water spray block installed at the top of the inner cavity of the frame through a water pipe, and the other side of the water pump is connected to the inner cavity of the nutrient solution storage tank through a water pipe. Thus, when in use, the water pump draws the nutrient solution through the water pipe and sprays it from the bottom of the water spray block. By utilizing the position of the water spray block, the water flow sprayed by the water spray block can fall straight into the inner cavity of the rear top culture frame.

[0013] Preferably, the top of the inner cavity of the collection frame is designed with a slope, the sponge block is located directly below the circulation belt, and the bottom of the culture frames on both the front and rear sides of the circulation belt is located within the inner cavity of the sponge block. Thus, during use, the sponge material of the sponge block prevents the falling water from colliding with the bottom of the inner cavity of the collection frame and splashing, thereby avoiding water splashing onto the inner wall of the frame. Combined with the position and shape of the sponge block, it is easy for the water falling from the bottom of the culture frames on both the front and rear sides to fall completely into the inner cavity of the sponge block.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This plant seedling cultivation device, through the combined use of a second horizontal plate structure and a second Velcro structure, operates by matching the positions of the second horizontal plate and the first horizontal plate at the bottom of the rear bottom cultivation frame. As the rear bottom cultivation frame rotates from back to front, the second horizontal plate contacts the first horizontal plate. With the rotation of the circulation belt, the discharge port is opened, facilitating the leakage of nutrient solution from the inner cavity of the cultivation frame. After the first horizontal plate separates from the second horizontal plate, the first horizontal plate automatically resets, causing the sealing block to seal the discharge port. This achieves the effect of automatically replacing the nutrient solution in the inner cavity of the cultivation tray, thereby improving the growth efficiency of the plant seedlings.

[0016] This plant seedling cultivation device, through the combined use of a frame structure and a sponge block structure, prevents water from colliding with the bottom of the collection frame and splashing during operation. This avoids water splashing onto the inner wall of the frame. The position and shape of the sponge block ensure that water falling from the bottom of the cultivation frames on both sides can completely fall into the inner cavity of the sponge block, thus preventing the discharged nutrient solution from splashing into the cultivation chamber and causing contamination, which would affect the normal growth of the plant seedlings.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-6As shown, a plant seedling cultivation device includes a frame 1. A circulating belt 2 is detachably installed in the middle of the inner cavity of the frame 1. Motors are detachably installed on the top left side and bottom right side of the frame 1. Rollers are detachably installed on the side of the motors that extend into the inner cavity of the frame 1. The circulating belt 2 is wound around the outer surface of the upper and lower rollers. In use, the motors on the left and right sides, which are identical in model and power, are used to control the upper and lower rollers to rotate forward and counterclockwise simultaneously. The output power of the motors is controlled by different buttons on the surface of the motors, which in turn controls the rotation speed of the rollers connected to the output shaft, i.e., the rotation speed of the circulating belt 2. Multiple mounting blocks 3 are fixedly installed on both sides of the outer surface of the circulating belt 2. Springs 4 are fixedly installed on the side of the mounting blocks 3 near the left and right side walls of the frame 1. A pull ring 5 is fixedly installed on the other side of the spring 4. A locking block 6 is fixedly installed on the side of the pull ring 5 away from the frame 1. An insertion rod 7 can be installed on the front side of the mounting block 3. The pull ring 5 is connected to the left side of the mounting block 3 through the spring 4. The shape and length of the cross-section of the locking block 6 match the length and cross-sectional shape of the bottom of the locking hole 8 on the side of the pull ring 5 facing the inserted rod 7 after installation. Thus, when in use, after the insertion rod 7 is inserted into the inner cavity of the mounting block 3, the pull ring 5 and the locking block 6 are used to fix the insertion rod 7 installed on the outer surface of the circulation belt 2 and the inner cavity of the mounting block 3. The side of the insertion rod 7 that extends into the inner cavity of the mounting block 3 facing the spring 4 has a locking hole 8. A culture frame 9 is movably installed on the front side of the insertion rod 7. A discharge port 10 is opened on the left side of the bottom of the inner cavity of the culture frame 9. The left side of the bottom of the culture frame 9 can rotate. A first torque shaft 11 is installed, and a first horizontal plate 12 is fixedly installed at the bottom of the first torque shaft 11. The shape and installation position of the sealing block 13 match the cross-sectional shape and opening position of the inner cavity of the discharge port 10. The first horizontal plate 12 is rotatably installed on the left side of the bottom of the culture frame 9 via the first torque shaft 11. Thus, under normal use, the first horizontal plate 12 is always in a horizontal state under the elastic force of the torsion spring 4 in the inner cavity of the first torque shaft 11. At this time, the sealing block 13 is installed in the inner cavity of the discharge port 10 to seal the culture frame 9 and prevent the nutrient solution from leaking from the inner cavity of the culture frame 9. The sealing block 13 is fixedly installed on the right side of the top of the first horizontal plate 12, and a first Velcro 14 is fixedly installed on the left side of the bottom of the first horizontal plate 12. A rotatable bottom is installed on the bottom left side of the inner cavity of the frame 1. A second torsion shaft 15 has a second horizontal plate 16 fixedly mounted at its bottom. The position of the second horizontal plate 16 matches the position of the first horizontal plate 12 at the bottom of the rear culture frame 9 of the circulation belt 2. The shape and position of the first hook and loop fastener 14 and the second hook and loop fastener 17 match. Thus, during use, when the rear culture frame 9 of the circulation belt 2 rotates from back to front, the bottommost rear culture frame 9 moves down, causing one side of the first horizontal plate 12 at the bottom of the bottommost rear culture frame 9 to overlap and contact one side of the second horizontal plate 16. That is, the first hook and loop fastener 14 and the second hook and loop fastener 17 are used to bond together, thereby increasing the contact time between the first horizontal plate 12 and the second horizontal plate 16, and thus increasing the time for the sealing block 13 to leave the inner cavity of the discharge port 10, facilitating the leakage of nutrient solution from the inner cavity of the culture frame 9.A second Velcro strap 17 is fixedly installed on the right side of the top of the second horizontal plate 16. A water pump 18 is fixedly installed on the top of the frame 1. A water spray block 19 is detachably installed on the bottom of the water pump 18. The bottom of the water spray block 19 has multiple spray nozzles. The water spray block 19 is located at the top of the inner cavity of the frame 1, directly above the rear culture frame 9. The shape of the bottom surface of the water spray block 19 is smaller than the cross-sectional shape of the inner cavity of the rear culture frame 9. One side of the water pump 18 is connected to the water spray block 19 installed at the top of the inner cavity of the frame 1 via a water pipe. The other side of the water pump 18 is connected to the inner cavity of the nutrient solution storage tank via a water pipe. Thus, when in use, the water pump 18 draws the nutrient solution through the water pipe and sprays it from the bottom of the water spray block 19. Utilizing the position of the water spray block 19, the water sprayed by the water spray block 19 can fall straight into the rear culture frame 9. The inner cavity of the culture frame 9 is located on the top side. A side plate 20 is hinged and mounted on the front side of the frame 1. A collection frame 21 is detachably mounted on the bottom of the frame 1. A mounting frame 22 is detachably mounted on the top of the inner cavity of the collection frame 21. A sponge block 23 is fixedly mounted in the middle of the mounting frame 22. The top of the inner cavity of the collection frame 21 is sloped. The sponge block 23 is located directly below the circulation belt 2. The bottoms of the culture frames 9 on both sides of the circulation belt 2 are within the inner cavity of the sponge block 23. Therefore, during use, the sponge material of the sponge block 23 prevents the falling water from colliding with the bottom of the inner cavity of the collection frame 21 and splashing, thus avoiding water splashing onto the inner wall of the frame 1. The position and shape of the sponge block 23 ensure that the water falling from the bottom of the culture frames 9 on both sides falls completely into the inner cavity of the sponge block 23.

[0027] Working principle: During operation, the insertion rod 7 and the culture frame 9 are first combined together. Then, the locking block 6 is pulled outward by the pull ring 5. After that, the combined insertion rod 7 is inserted into the inner cavity of the mounting block 3. Finally, the pull ring 5 is released. Under the elastic force of the spring 4, the locking block 6 automatically extends into the inner cavity of the mounting block 3 and into the inner cavity of the locking hole 8 on one side of the insertion rod 7, thereby fixing the insertion rod 7 and the circulation belt 2. That is, fixing the insertion rod 7 to the outer surface of the circulation belt 2. Then, the mounting frame 22 is installed at the top of the inner cavity of the collection frame 21. Then, the collection frame 21 is inserted into the bottom of the inner cavity of the frame 1.

[0028] In formal use, the rotation speed of the circulating belt 2 from front to back is controlled by the motors on both sides of the frame 1. Then, the water pump 18 is started to draw the nutrient solution into the spray block 19 and spray it out from the spray nozzle at the bottom of the spray block 19. If it is not necessary to completely replace the culture solution in the inner cavity of the culture frame 9, the motors on the left and right sides of the frame 1 can be adjusted to increase the rotation speed of the circulating belt 2. When the rear bottom culture frame 9 rotates forward, the first Velcro 14 and the second Velcro 17 are used to cause the second horizontal plate 16 to drive the first horizontal plate 12 to deflect upward, thereby separating the sealing block 13 from the discharge port 10, which facilitates the flow of nutrients into the inner cavity of the rear bottom culture frame 9. When the nutrient solution leaks, as the circulation belt 2 rotates, the first Velcro 14 and the second Velcro 17 separate. At this time, the first horizontal plate 12 and the second horizontal plate 16 return to horizontal, allowing the sealing block 13 to move into the discharge port 10, thereby sealing the culture frame 9. At this time, as long as the circulation belt 2 is fast enough, the discharge port 10 will be open for a shorter time, meaning that the amount of nutrient solution leaking from the inner cavity of the culture frame 9 will be less. When it is necessary to replace the nutrient solution in the inner cavity of the culture frame 9, it is only necessary to control the rotation speed of the circulation belt 2 to be slower, thereby controlling the length of time the discharge port 10 is open, so as to fully drain the nutrient solution from the inner cavity of the culture frame 9 and facilitate the replacement of the nutrient solution in the inner cavity of the culture frame 9.

[0029] Meanwhile, during use, the sponge material of the sponge block 23 prevents the falling water from colliding with the bottom of the inner cavity of the collection frame 21 and splashing, thus avoiding water splashing onto the inner wall of the frame 1. Combined with the position and shape of the sponge block 23, the water falling from the bottom of the front and rear cultivation frames 9 can fall completely into the inner cavity of the sponge block 23.

[0030] In summary, compared with similar devices, this plant seedling cultivation device has the advantages of automatically replacing the nutrient solution inside the cultivation tray, improving the growth efficiency of plant seedlings, and preventing the discharged nutrient solution from splashing into the cultivation box and causing pollution, thus affecting the normal growth of plant seedlings.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
