Description

Technical Field

[0001] The present invention relates to the technical field of seedling cultivation and planting equipment, and particularly to a seedling cultivation equipment for Chinese herbal medicine planting. Background Technique

[0002] Chinese herbal medicine refers to natural medicines used for preventing, diagnosing, treating diseases or regulating the physiological functions of the human body under the guidance of traditional Chinese medicine theory. The medicinal components are mainly taken from plants, animals and minerals. For example, the roots, stems, leaves of plants, pilose antler, snake gallbladder in animals, gypsum, cinnabar in minerals, etc. Chinese herbal medicine pays attention to the overall balance of the human body and achieves the purpose of "treating the disease by seeking the root cause" by regulating qi and blood, yin and yang, and zang-fu organs.

[0003] Nowadays, in order to provide sufficient Chinese herbal medicine, artificial planting of Chinese herbal medicine in some plants has begun. During the planting process, the primary task is the cultivation of Chinese herbal medicine seedlings. Seeds are planted in special cultivation containers. After the seeds germinate and grow into seedlings, they are transplanted, so that the Chinese herbal medicine seedlings can grow in a suitable environment and ensure the survival rate of the seedlings.

[0004] However, nowadays, during the process of transplanting seedlings, most of them still use the method of pulling to take out the seedlings from the cultivation containers and then transplant them. This method is likely to cause strain to the seedlings during the transplanting process, affecting the subsequent growth of the seedlings, and seriously may directly cause the death of the seedlings. Summary of the Invention

[0005] The purpose of the present invention is to provide a seedling cultivation equipment for Chinese herbal medicine planting to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention is a seedling cultivation equipment for Chinese herbal medicine planting, including a cultivation dish for planting Chinese herbal medicine seedlings. A limiting ring is provided on the cultivation dish to limit the soil covering depth, making the bottom of the inner cavity of the cultivation dish in a hollow state, facilitating water storage and drainage in the dish. A transplanting mechanism is arranged in the cultivation dish. The transplanting mechanism is separable from the cultivation dish, facilitating the removal of Chinese herbal medicine seedlings from the cultivation dish through the transplanting component for transplantation. The transplanting mechanism is specifically composed of a transplanting cylinder, a support plate and an adjustment component. The transplanting cylinder is arranged in the cultivation dish. The support plate is movably arranged in the transplanting cylinder for supporting and storing the planting soil. The adjustment component is arranged on the transplanting cylinder for adjusting the position of the support plate to facilitate the transplantation of Chinese herbal medicine seedlings from the transplanting cylinder.

[0008] Further, the adjusting assembly is composed of an adjusting grid plate and an adjusting cylinder. The adjusting grid plate is installed at the bottom of the transplantation cylinder, and the number of the adjusting grid plates is set to be multiple and arranged in a ring shape. The adjusting grid plate is made of a deformable plastic material. The adjusting cylinder is sleeved outside the transplantation cylinder. The bottom thickness of the adjusting cylinder is greater than the top thickness, and the lower position of the inner circle of the adjusting cylinder is provided with an inclined surface. During the upward movement of the adjusting cylinder, its bottom gives a squeezing force to the adjusting grid plate, causing the adjusting grid plate to bend inward and form a support for the support plate.

[0009] Further, the support plate is provided with water leakage through holes for draining excess water when watering the soil, avoiding the formation of water accumulation on the support plate. A sponge pad is arranged in the water leakage through holes for reducing the loss of the planted soil.

[0010] Further, the transplantation cylinder is provided with an external thread, and the top opening of the adjusting cylinder is provided with an internal thread. After the adjusting cylinder is sleeved on the transplantation cylinder, the internal thread is threadedly connected with the external thread by rotation, thereby ensuring the firm connection between the adjusting cylinder and the transplantation cylinder.

[0011] Further, the transplantation cylinder is provided with a hook ring for facilitating the user to take the transplantation cylinder. A sliding inner cavity is opened on the transplantation cylinder. A pulling frame is arranged on the hook ring, and the pulling frame is in a sliding connection state with the sliding inner cavity. A first spring is sleeved on the pulling frame for giving a downward pressure to the pulling frame, so that the hook ring is in a stable placement state without external force. A clamping groove is opened at the top of the adjusting cylinder. An insertion block is installed on the pulling frame, and the bottom of the insertion block extends into the clamping groove and is adapted to the clamping groove. After the adjusting cylinder and the transplantation cylinder are threadedly connected, the adjusting cylinder is further limited by the limitation of the insertion block and the clamping groove, ensuring the firm installation of the adjusting cylinder.

[0012] Further, a partition frame is installed in the transplantation cylinder. The number of the partition frames is set to be multiple and arranged in a ring shape. The partition frames are inclined in the transplantation cylinder, and an annular inner groove can be formed around the planted soil through the partition frames.

[0013] Furthermore, an annular airbag is provided on the transplantation cylinder, and an avoidance groove is formed on the adjustment cylinder for avoiding the annular airbag to prevent extrusion of the annular airbag. A connecting air cylinder is installed on the transplantation cylinder, with one end of the connecting air cylinder extending into the partition frame and the other end communicating with the annular airbag. A piston is arranged in the connecting air cylinder, and a push rod is installed on the side of the piston away from the annular airbag. The push rod extends out of the connecting air cylinder, and a second spring is sleeved on the push rod. The second spring is used to connect the piston and the connecting air cylinder, so that the piston is in a stable state in the connecting air cylinder without external force. A moving plate is slidably installed in the partition frame, and a moving block is installed on the moving plate. One side of the moving block extends out of the partition frame. A third spring is installed on the moving plate and connected to the partition frame. A T-shaped convex block is arranged on one side of the moving plate. Under the push of the push rod, the T-shaped convex block pushes the moving plate to move, and then pushes the moving block to move.

[0014] Furthermore, the avoidance groove is composed of a lower avoidance groove and an upper avoidance groove. When the adjustment cylinder is in a threaded connection state with the transplantation cylinder, the annular airbag is located in the lower avoidance groove. When the adjustment cylinder rotates and moves downward, the annular airbag is first squeezed, and the squeezing force will indirectly push the moving block to move and insert into the falling soil to slow down the falling of the soil. After the adjustment cylinder descends to a certain height, the annular airbag is avoided through the upper avoidance groove. At this time, under the action of the second spring and the third spring, the moving block shrinks into the partition frame, facilitating the discharge of the soil from the transplantation cylinder.

[0015] Furthermore, an annular frame is rotatably installed on the adjustment cylinder, and the annular frame is in a sliding connection state with the transplantation cylinder. A sliding groove is formed on the transplantation cylinder, and a pressing frame is arranged in the sliding groove and connected to the annular frame. When the adjustment cylinder rotates and descends on the transplantation cylinder, it will drive the annular frame to descend, and then drive the pressing frame to descend, and the soil for planting is pressed through the pressing frame to facilitate the discharge of the soil from the transplantation cylinder.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention adopts the method of separating the culture dish and the transplantation cylinder, so that the planting of medicinal seedlings can be in a state of being movable at any time, and there is no need to pull out the seedlings during the moving process, avoiding damage to the seedlings. At the same time, the adjustment cylinder and the adjustment grid plate are used to limit and fix and separate the support plate. After selecting the planting position, the seedlings can be moved above the planting position. By rotating the adjustment cylinder to release the extrusion on the adjustment grid plate, the adjustment grid plate returns to its initial state after losing the extrusion. In this case, the support plate, the planting soil, and the Chinese herbal medicine seedlings all fall downward under the influence of gravity until they fall into the planting area, thus completing the transplantation of the Chinese herbal medicine seedlings without damaging the seedlings and ensuring the healthy growth of the subsequent Chinese herbal medicine seedlings.

[0018] (2) In the present invention, a plurality of annularly arranged partition frames are provided on the inner wall of the transplantation cylinder, thereby forming a plurality of inner grooves around the soil where the seedlings are planted. During the growth of the seedlings, the planted soil will gradually take shape under the irrigation of water flow. When transplanting the seedlings, the planted soil detaches from the transplantation cylinder and falls into the planting area. At this time, when the soil in the planting area covers the soil with the seedlings planted, due to the setting of the inner grooves, the contact between the two sides of the soil will be closer, thereby reducing the probability of the Chinese herbal medicine seedlings falling after transplantation and ensuring the healthy planting of the seedlings.

[0019] (3) During the process of transplanting Chinese herbal medicine seedlings in the present invention, the annular airbag will be squeezed by the adjustment cylinder, and the squeezed air flow will push the piston and the push rod to move, and then push the moving plate and the moving block to move, so that the moving block extends out of the partition frame. Under the action of the moving block, the falling soil will be squeezed, slowing down the falling speed of the soil and avoiding damage to the root system of the seedlings caused by the too fast falling speed of the soil. At the same time, when the moving block pushes the soil, it will also make the soil adhering to the inner wall of the transplantation cylinder detach, ensuring the stable falling of the transplanted soil and the stable transplantation of Chinese herbal medicine seedlings.

[0020] (4) During the process of transplanting Chinese herbal medicine seedlings in the present invention, the downward movement of the adjustment cylinder will drive the annular frame and the downward pressure frame to move downward. Under the action of the downward pressure frame, a downward thrust will be formed above the planted soil, causing the entire soil with the seedlings planted to move downward as a whole. Thereby, the soil adhering to the inner wall of the transplantation cylinder can be pushed, ensuring that the soil can fall more comprehensively and further ensuring the stable planting of Chinese herbal medicine seedlings.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0034] 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.

[0035] Please refer to Figures 1-9As shown in the figure, the present invention is a seedling raising device for planting Chinese herbal medicines, including a cultivation dish 1 for planting Chinese herbal medicine seedlings. A limiting ring is provided on the cultivation dish 1 to limit the covering soil depth, making the bottom of the inner cavity of the cultivation dish 1 in a hollow state, facilitating water storage and drainage in the dish. A drain pipe 7 is installed on the cultivation dish 1, and the drain pipe 7 is located below the limiting ring, which can not only discharge excess water but also store water in the cultivation dish 1. Thus, the rhizomes of Chinese herbal medicine seedlings can extend better downward. A transplanting mechanism is arranged in the cultivation dish 1, and the transplanting mechanism is separable from the cultivation dish 1, facilitating the removal of Chinese herbal medicine seedlings from the cultivation dish 1 through the transplanting component for transplantation. The transplanting mechanism is specifically composed of a transplanting cylinder 2, a support plate 5, and an adjustment component. The transplanting cylinder 2 is arranged in the cultivation dish 1, and the support plate 5 is movably arranged in the transplanting cylinder 2 for supporting and storing the planting soil. Leakage through holes are provided on the support plate 5 for discharging excess water when watering the soil, preventing water from accumulating on the support plate 5. A sponge pad is arranged in the leakage through holes to reduce the loss of planting soil. The adjustment component is arranged on the transplanting cylinder 2 for adjusting the position of the support plate 5, facilitating the transplantation of Chinese herbal medicine seedlings from the transplanting cylinder 2. The adjustment component is composed of an adjustment grid plate 4 and an adjustment cylinder 3. The adjustment grid plate 4 is installed at the bottom of the transplanting cylinder 2, and the number is set to multiple, arranged in a ring shape. The adjustment grid plate 4 is made of a deformable plastic material. The adjustment cylinder 3 is sleeved outside the transplanting cylinder 2. The bottom thickness of the adjustment cylinder 3 is greater than the top thickness, and the lower position of the inner circle of the adjustment cylinder 3 is provided with an inclined surface. During the upward movement of the adjustment cylinder 3, its bottom gives a squeezing force to the adjustment grid plate 4, causing the adjustment grid plate 4 to bend inward and form a support for the support plate 5. External threads are provided on the transplanting cylinder 2, and internal threads are provided at the top opening of the adjustment cylinder 3. After the adjustment cylinder 3 is sleeved on the transplanting cylinder 2, the internal threads are threadedly connected with the external threads by rotation, thus ensuring the firm connection between the adjustment cylinder 3 and the transplanting cylinder 2.

[0036] A hook ring 6 is arranged on the transplanting cylinder 2 for facilitating the user to pick up the transplanting cylinder 2. A sliding inner cavity is provided on the transplanting cylinder 2. A pulling frame 8 is arranged on the hook ring 6, and the pulling frame 8 is in a sliding connection state with the sliding inner cavity. A first spring is sleeved on the pulling frame 8 for giving a downward pressure to the pulling frame 8, so that the hook ring 6 is in a stable placement state without external force. A clamping groove is provided at the top of the adjustment cylinder 3. An insertion block 9 is installed on the pulling frame 8, and the bottom of the insertion block 9 extends into the clamping groove and is adapted to the clamping groove. After the adjustment cylinder 3 and the transplanting cylinder 2 are threadedly connected, the adjustment cylinder 3 is further limited by the restriction of the insertion block 9 and the clamping groove, ensuring the firm installation of the adjustment cylinder 3.

[0037] A partition frame 10 is installed inside the transplantation cylinder 2. The number of partition frames 10 is set to be multiple and arranged in a ring shape. The partition frames 10 are inclined inside the transplantation cylinder 2. An annular inner groove can be formed around the planted soil through the partition frames 10.

[0038] An annular airbag 11 is arranged on the transplantation cylinder 2. An avoidance groove is opened on the adjustment cylinder 3. The avoidance groove is composed of a lower avoidance groove 19 and an upper avoidance groove 20. When the adjustment cylinder 3 is in a threaded connection state with the transplantation cylinder 2, the annular airbag 11 is located inside the lower avoidance groove 19. When the adjustment cylinder 3 rotates and moves downward, the annular airbag 11 is first squeezed. The squeezing force will indirectly push the moving block 16 to move and insert into the falling soil to slow down the falling of the soil. After the adjustment cylinder 3 descends to a certain height, the upper avoidance groove 20 avoids the annular airbag 11. At this time, under the action of the second spring and the third spring, the moving block 16 contracts into the partition frame 10 to facilitate the discharge of the soil from the transplantation cylinder 2. The avoidance groove is used to avoid the annular airbag 11 and prevent it from being squeezed. A connecting air cylinder 12 is installed on the transplantation cylinder 2. One end of the connecting air cylinder 12 extends into the partition frame 10, and the other end of the connecting air cylinder 12 is communicated with the annular airbag 11. A piston 13 is arranged inside the connecting air cylinder 12. A push rod 14 is installed on the side of the piston 13 away from the annular airbag 11. The push rod 14 extends out of the connecting air cylinder 12. A second spring is sleeved on the push rod 14. The second spring is used to connect the piston 13 and the connecting air cylinder 12 to make the piston 13 in a stable state inside the connecting air cylinder 12 without external force. A moving plate 15 is slidably installed inside the partition frame 10. A moving block 16 is installed on the moving plate 15. One side of the moving block 16 extends outside the partition frame 10. A third spring is installed on the moving plate 15. The third spring is connected to the partition frame 10. A T-shaped convex block is arranged on one side of the moving plate 15. Under the push of the push rod 14, the T-shaped convex block pushes the moving plate 15 to move, and then pushes the moving block 16 to move.

[0039] An annular frame 17 is rotatably installed on the adjustment cylinder 3. The annular frame 17 is in a sliding connection state with the transplantation cylinder 2. A sliding groove is opened on the transplantation cylinder 2. A pressing frame 18 is arranged inside the sliding groove. The pressing frame 18 is connected to the annular frame 17. When the adjustment cylinder 3 rotates and descends on the transplantation cylinder 2, it will drive the annular frame 17 to descend, and then drive the pressing frame 18 to descend. The planted soil is pressed through the pressing frame 18 to facilitate the discharge of the soil from the transplantation cylinder 2.

[0040] In this embodiment, for the setting of the culture dish 1, multiple culture dishes 1 can be connected to form a culture plate for planting multiple Chinese herbal medicine seedlings simultaneously;

[0041] The specific use of the cultivation dish 1 is as follows: after the transplanting cylinder 2, the adjusting cylinder 3 and the supporting plate 5 are placed in the cultivation dish 1, the supporting plate 5 is squeezed and positioned by the adjusting cylinder 3 and the adjusting grid plate 4, so that the supporting plate 5 is in a stable placement state in the transplanting cylinder 2, and then the planting soil can be placed on the supporting plate 5, and the seedlings can be cultivated. During the planting process, the water flows downward after passing through the planting soil, and falls into the bottom inner cavity of the cultivation dish 1 through the water leakage holes on the supporting plate 5, and then discharged through the drainage pipe 7, thereby preventing the water from gathering in the transplanting cylinder 2 and reducing the damage to the roots and stems of the Chinese herbal medicine seedlings;

[0042] During the seedling transplanting process, the transplanting cylinder 2 and the adjusting cylinder 3 can be driven to rise and detach from the cultivation dish 1 by pulling the hook ring 6, and then the adjusting cylinder 3 can be rotated to move the adjusting cylinder 3 downward on the transplanting cylinder 2, thereby releasing the squeezing of the adjusting grid 4 and restoring the adjusting grid 4 to a vertical state. At this time, the bottom of the support plate 5 is not affected by the squeezing force and will fall downward, thereby driving the planting soil and the Chinese herbal seedlings to move downward and detach from the transplanting cylinder 2. In this way, there is no need to pull the Chinese herbal seedlings when transplanting, thereby improving the protection of the Chinese herbal seedlings.

[0043] During the process of transplanting seedlings, the annular airbag 11 will be squeezed when the adjusting cylinder 3 moves downward. The annular airbag 11 will be squeezed to push the piston 13 to move, and then push the pushing rod 14 to move, and then push the moving plate 15 to move, and then push the moving block 16 to move, so that the moving block 16 forms a squeezing and clamping state on the falling soil, slowing down the falling of the planting soil, and preventing the planting soil from falling too fast and causing damage to the roots and stems of the seedlings. At the same time, it can also form a driving force for the planting soil near the edge of the transplanting cylinder 2, preventing the soil from adhering to the inner wall of the transplanting cylinder 2, and ensuring the stable falling of the planting soil. At the same time, in the process of the adjusting cylinder 3 sliding down, the annular frame 17 will be driven to descend, and then the downward pressure frame 18 will be driven to descend, thereby forming a downward pressure on the planting soil, helping the planting soil to separate from the transplanting cylinder 2, and ensuring the transplanting stability of the Chinese herbal medicine seedlings.

[0044] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
