Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1-8, an embodiment of the present invention is: A seedling raising device for improving the seedling raising rate, including a base 1. The inner wall of the base 1 is fixedly connected with a tray 2. The inner wall of the tray 2 is slidably connected with a seedling raising tray 3. The inner wall of the base 1 is fixedly connected with a cylinder 4. The inner wall of the seedling raising tray 3 is slidably connected with a seedling raising cavity 5. The output end of the cylinder 4 is fixedly connected with a collection box 6. The top of the collection box 6 is fixedly connected with a pressing plate 7. The bottom of the seedling raising cavity 5 is fixedly connected with a first elastic telescopic rod 8. The telescopic end of the first elastic telescopic rod 8 is fixedly connected with a pressure receiving plate 9. The top of the pressure receiving plate 9 is fixedly connected with a first connecting column 10. The top of the first connecting column 10 is fixedly connected with a cross plate 11. The circumferential surface of the seedling raising cavity 5 is fixedly connected with a limiting ring 12. The bottom of the seedling raising cavity 5 is fixedly connected with a buffer ring 13. When the device is in use, the cylinder 4 will start, and the output end of the cylinder 4 will drive the collection box 6 to move. At this time, the movement of the collection box 6 will drive the pressing plate 7 to move. After the pressing plate 7 moves a certain distance, the top of the pressing plate 7 will come into contact with the buffer ring 13. At this time, the cylinder 4 will continue to drive the collection box 6 to rise. The cylinder 4 will squeeze and push the buffer ring 13, and the buffer ring 13 will push the seedling raising cavity 5 to rise. At this time, the collection box 6 can push the seedling raising cavity 5 to rise a certain distance. In reality, the growth speeds of seedling plants are not exactly the same, although they may be in the same growth environment. The growth speed of seedling plants is affected by various factors, including the characteristics of the seeds themselves, environmental conditions, management measures, etc. When the pressing plate 7 pushes the seedling raising cavity 5 to rise, it is convenient for workers to transfer and unify the seedling plants with different growth states, improving the subsequent planting efficiency of seedling plants, enhancing the management efficiency of seedling plant cultivation, and improving the accuracy of subsequent irrigation and fertilization. A slider 14 is fixedly connected to the right side of the seedling raising tray 3. A spraying mechanism 15 is arranged on the top of the tray 2. A protection mechanism 16 is arranged on the inner wall of the tray 2. The cross plate 11 contacts the seedling raising cavity 5, the limiting ring 12 contacts the seedling raising tray 3, the slider 14 is slidably connected to the inner wall of the tray 2, and the tray 2 contacts the seedling raising tray 3. At the same time, during the rising process of the pressing plate 7, the pressing plate 7 will contact and squeeze the pressure receiving plate 9 to push the pressure receiving plate 9. At this time, the pressure receiving plate 9 will move upward. During the rising process of the pressure receiving plate 9, the pressure receiving plate 9 will drive the first connecting column 10 to rise. During the movement of the first connecting column 10, the first connecting column 10 will drive the cross plate 11 to rise. When the cross plate 11 rises, the cross plate 11 can open the opening at the bottom of the seedling raising cavity 5, and the nutrient solution inside the seedling raising cavity 5 can be discharged through the opening at the bottom of the seedling raising cavity 5. If the nutrient solution is not replaced for a long time, it may become a breeding ground for microorganisms such as bacteria, fungi, and algae, increasing the risk of disease occurrence. Regularly discharging the nutrient solution can help remove substances that may breed germs, thereby reducing the occurrence of root rot or diseases of seedling plants and improving the seedling raising quality of the device.

[0016] The spraying mechanism 15 includes a bracket 1501, a nutrient solution box 1502, a movable long rod 1503, a sealing block 1504, a second connecting column 1505, a water pipe 1506, a first fixing block 1507, and a nozzle pipe 1508. The bracket 1501 is fixedly connected to the top of the tray 2. The nutrient solution box 1502 is fixedly connected to the top of the bracket 1501. The movable long rod 1503 is fixedly connected to the rear of the collection box 6. The sealing block 1504 is slidably connected to the inner wall of the nutrient solution box 1502. The second connecting column 1505 is fixedly connected to the inner wall of the sealing block 1504. The first fixing block 1507 is fixedly connected to the inner wall of the bracket 1501. The nozzle pipe 1508 is fixedly connected to the inner wall of the first fixing block 1507. One end of the water pipe 1506 is fixedly connected and communicated with the nutrient solution box 1502. The other end of the water pipe 1506 is fixedly connected and communicated with the nozzle pipe 1508. When the device is started, the upward movement of the collection box 6 can drive the movable long rod 1503 to move. After the movable long rod 1503 moves a certain distance, the movable long rod 1503 will contact and squeeze the second connecting column 1505, causing the second connecting column 1505 to rise. The rise of the second connecting column 1505 will drive the sealing block 1504 to rise. During the rise of the sealing block 1504, the sealing block 1504 can open the opening at the bottom of the nutrient solution box 1502. At this time, the nutrient solution inside the nutrient solution box 1502 can enter the inside of the water pipe 1506 through the opening at the bottom of the nutrient solution box 1502. The nutrient solution inside the water pipe 1506 will enter the inside of the nozzle pipe 1508. At this time, the nutrient solution inside the nozzle pipe 1508 can be sprayed out through the nozzles of the nozzle pipe 1508 itself. At this time, the nutrient solution can be sprayed into the inside of the seedling raising cavity 5. The discharge of the new nutrient solution in the nozzle pipe 1508 is synchronized with the discharge of the nutrient solution inside the seedling raising cavity 5, which can gradually replace the old solution with the new nutrient solution, reduce the situation of mutation, give the plant roots a gentle adaptation process, and avoid the growth discomfort of the seedling due to sudden environmental changes. The spraying mechanism 15 further includes a connecting rod 1509, a spring block 1510, a connecting long column 1511, a first inclined block 1512, and a pull rod 1513. The connecting rod 1509 is fixedly connected to the rear of the seedling tray 3. The spring block 1510 is fixedly connected to the inner wall of the connecting rod 1509. The connecting long column 1511 is slidably connected to the inner wall of the tray 2. The first inclined block 1512 is fixedly connected to the rear end of the connecting long column 1511. The pull rod 1513 is fixedly connected to the front end of the connecting long column 1511. The connecting rod 1509 contacts the tray 2. The first inclined block 1512 and the tray 2 are connected by a spring. Before the device is used, when the worker pushes the seedling tray 3 into the inside of the tray 2, the seedling tray 3 will drive the connecting rod 1509 to move. The connecting rod 1509 will drive the spring block 1510 to move. During the movement of the spring block 1510, the inclined surface of the inclined block of the spring block 1510 itself will contact the inner wall of the tray 2. At this time, the spring block 1510 will be squeezed and move telescopically. When the worker pushes the rear part of the seedling tray 3 to contact the inner wall of the tray 2,At this time, the spring block 1510 will reset and drive the inclined block of itself to move. The inclined block of the spring block 1510 will get stuck with the tray 2. At this time, the seedling tray 3 cannot move. At the same time, when the worker needs to pull out the seedling tray 3, only need to pull the pull rod 1513 to move in advance. The pull rod 1513 will drive the connecting long column 1511 to move. The connecting long column 1511 will drive the inclined block one 1512 to move. When the inclined block one 1512 moves, it will push the inclined block of the connecting rod 1509 through its own inclined plane. At this time, the limit of the connecting rod 1509 is released, and the seedling tray 3 can be pulled out. This operation can ensure environmental stability. The displacement or vibration of the seedling cavity may cause uneven liquid distribution, resulting in unstable nutrient solution concentration in local areas, which will affect the growth of the seedling. The fixed seedling cavity can avoid this situation and ensure that each seedling is always in a stable environment.

[0017] Working principle: When the device is in use, the air cylinder 4 will start. The output end of the air cylinder 4 will drive the collection box 6 to move. At this time, the movement of the collection box 6 will drive the extrusion plate 7 to move. After the extrusion plate 7 moves a certain distance, the top of the extrusion plate 7 will contact the buffer ring 13. At this time, the air cylinder 4 will continue to drive the collection box 6 to rise. The air cylinder 4 will squeeze and push the buffer ring 13, and the buffer ring 13 will push the seedling cavity 5 to rise. At this time, the collection box 6 can push the seedling cavity 5 to rise a certain distance. In reality, the growth rates of seedlings are not exactly the same. Although they may be in the same growth environment, the growth rate of seedlings is affected by various factors, including the characteristics of the seeds themselves, environmental conditions, management measures, etc. When the extrusion plate 7 pushes the seedling cavity 5 to rise, it is convenient for workers to transfer and unify the seedlings with different growth states, improve the subsequent seedling planting efficiency, improve the management efficiency of seedling cultivation, and improve the accuracy of subsequent irrigation and fertilization. At the same time, during the rising process of the extrusion plate 7, the extrusion plate 7 will contact and push the pressure-receiving plate 9. At this time, the pressure-receiving plate 9 will move upward. During the rising process of the pressure-receiving plate 9, the pressure-receiving plate 9 will drive the connecting column one 10 to rise. During the moving process of the connecting column one 10, the connecting column one 10 will drive the cross plate 11 to rise. When the cross plate 11 rises, the cross plate 11 can open the opening at the bottom of the seedling cavity 5. The nutrient solution inside the seedling cavity 5 can be discharged through the opening at the bottom of the seedling cavity 5. If the nutrient solution is not replaced for a long time, it may become a breeding ground for microorganisms such as bacteria, fungi, and algae, increasing the risk of disease occurrence. Regularly discharging the nutrient solution can help remove substances that may breed germs, thereby reducing the occurrence of root rot or diseases of the seedlings and improving the seedling raising quality of the device.

[0018] When the device is started, the upward movement of the collection box 6 can drive the moving long rod 1503 to move. After the moving long rod 1503 moves a certain distance, the moving long rod 1503 will contact and press the second connecting column 1505, causing the second connecting column 1505 to rise. The rise of the second connecting column 1505 will drive the sealing block 1504 to rise. During the rise of the sealing block 1504, the sealing block 1504 can open the opening at the bottom of the nutrient solution box 1502. At this time, the nutrient solution inside the nutrient solution box 1502 can enter the inside of the water pipe 1506 through the opening at the bottom of the nutrient solution box 1502. The nutrient solution inside the water pipe 1506 will enter the inside of the spray head pipe 1508. At this time, the nutrient solution inside the spray head pipe 1508 can be sprayed out through the spray heads of the spray head pipe 1508 itself. At this time, the nutrient solution can be sprayed into the inside of the seedling cultivation cavity 5. The discharge of the new nutrient solution in the spray head pipe 1508 and the discharge of the nutrient solution inside the seedling cultivation cavity 5 are carried out synchronously, which can gradually replace the old liquid with the new nutrient solution, reduce the situation of mutations, give the plant roots a gentle adaptation process, and avoid the growth discomfort of the seedling due to sudden environmental changes. Before using the device, when the worker pushes the seedling cultivation tray 3 into the inside of the tray 2, the seedling cultivation tray 3 will drive the connecting rod 1509 to move, and the connecting rod 1509 will drive the spring block 1510 to move. During the movement of the spring block 1510, the inclined surface of the inclined block of the spring block 1510 itself will contact the inner wall of the tray 2. At this time, the spring block 1510 will be squeezed and move telescopically. When the worker pushes the rear part of the seedling cultivation tray 3 to contact the inner wall of the tray 2, at this time, the spring block 1510 will be reset and drive its own inclined block to move. The inclined block of the spring block 1510 itself will be stuck with the tray 2. At this time, the seedling cultivation tray 3 cannot move. At the same time, when the worker needs to pull out the seedling cultivation tray 3, only need to pull the pull rod 1513 to move in advance. The pull rod 1513 will drive the connecting long column 1511 to move, and the connecting long column 1511 will drive the first inclined block 1512 to move. When the first inclined block 1512 moves, it will push the inclined block of the connecting rod 1509 itself through its own inclined surface. At this time, the limit of the connecting rod 1509 is released, and the seedling cultivation tray 3 can be pulled out. This operation can ensure environmental stability. The displacement or vibration of the seedling cavity may cause uneven liquid distribution, resulting in unstable nutrient solution concentration in local areas, which will affect the growth of the seedling. The fixed seedling cultivation cavity can avoid this situation and ensure that each seedling is always in a stable environment.

The second fixed block 1601 is fixedly connected to the inner wall of the movable long rod 1503. The third connecting column 1602 is fixedly connected to the front part of the second fixed block 1601. The sunshade 1603 is fixedly connected to the circumferential surface of the third connecting column 1602. When the device is placed outdoors for use, the sunlight outdoors is too strong. At this time, the upward movement of the movable long rod 1503 will drive the second fixed block 1601 to move. The movement of the second fixed block 1601 will drive the third connecting column 1602 to move. When the third connecting column 1602 moves, it will drive the sunshade 1603 to move. After the sunshade 1603 moves a certain distance, the sunshade 1603 can isolate the seeds and seedlings inside the seedling cultivation cavity 5 from the sunlight to a certain extent, avoiding the outdoor sunlight from burning the seeds and seedlings cultivated inside 5 when the outdoor sunlight is strong, improving the survival rate of the seeds and seedlings cultivated outdoors, and improving the use efficiency of the device. The protection mechanism 16 further includes a connecting plate 1604, a second inclined block 1605, a moving plate 1606, a third inclined block 1607, and a second elastic telescopic rod 1608.

The third connecting column 1602 is slidably connected to the inner wall of the bracket 1501. The second inclined block 1605 is in contact with the third inclined block 1607. The moving plate 1606 is in contact with the bracket 1501. The sunshade 1603 is in contact with the tray 2. At the same time, during the upward movement of the sunshade 1603, the movement of the sunshade 1603 will drive the connecting plate 1604 to move upward. During the upward movement of the connecting plate 1604, the connecting plate 1604 will drive the second inclined block 1605 to move. During the movement of the second inclined block 1605, the third inclined block 1607 will be pushed by the extrusion of the second inclined block 1605. At this time, the second inclined block 1605 will push the third inclined block 1607 to move through the inclined plane. The movement of the third inclined block 1607 will drive the moving plate 1606 to move. The movement of the moving plate 1606 can close the opening at the top of the bracket 1501, avoiding the direct contact between the strong outdoor sunlight and the seeds and seedlings, and avoiding the excessive evaporation of the water in the seeds and seedlings, resulting in the death of the seeds and seedlings, and further improving the survival rate of seedling cultivation.

[0020] Working principle: When the device is placed outdoors for use, the sunlight outdoors is too strong. At this time, the upward movement of the movable long rod 1503 will drive the movement of the second fixed block 1601. The movement of the second fixed block 1601 will drive the movement of the third connecting column 1602. When the third connecting column 1602 moves, it will drive the movement of the sunshade 1603. After the sunshade 1603 moves a certain distance, the sunshade 1603 can isolate the seeds and seedlings inside the seedling cultivation cavity 5 from the sunlight to a certain extent, avoiding the sunlight outdoors from burning the seeds and seedlings cultivated inside 5 when the sunlight outdoors is strong, improving the survival rate of the seeds and seedlings cultivated outdoors, improving the use efficiency of the device. At the same time, during the upward movement of the sunshade 1603, the movement of the sunshade 1603 will drive the upward movement of the connecting plate 1604. During the upward movement of the connecting plate 1604, the connecting plate 1604 will drive the movement of the second inclined block 1605. During the movement of the second inclined block 1605, the third inclined block 1607 will be pushed by the extrusion of the second inclined block 1605. At this time, the second inclined block 1605 will push the third inclined block 1607 to move through the inclined plane. The movement of the third inclined block 1607 will drive the movement of the movable plate 1606.
