Description

Technical Field

[0001] This invention belongs to the field of forest tree seedling cultivation, specifically relating to a heat preservation device for protecting forest tree seedlings from cold and pests. Background Technology

[0002] Modern forestry seedling cultivation has evolved from traditional bare-root field cultivation to an intensive cultivation system primarily based on container seedling production. By precisely adjusting lightweight substrates, controlling the greenhouse environment, implementing integrated water and fertilizer drip irrigation, and mechanized seeding, the survival rate, uniformity, and stress resistance of seedlings have been significantly improved. This technology effectively shortens the seedling cultivation cycle, ensures the integrity of the root system, and provides high-quality seedlings for afforestation projects, serving as an important foundation for promoting efficient and sustainable forestry development.

[0003] Patent CN221948835U discloses a device for raising forest seedlings, belonging to the field of forest seedling technology. It includes a water tank with an opening on the top surface and a frame plate embedded therein. The frame plate has several embedded holes arranged in an array, and seedling pots are inserted into the embedded holes. Support columns are fixed to the four corners of the top surface of the water tank, and mounting frames are fixed to the support columns. A water spraying mechanism and a sunshade mechanism are fixedly installed on the mounting frames. The seedling pot includes an outer shell and a geotextile. The geotextile is laid inside the outer shell and extends outside the outer shell. Several water-permeable holes are opened at the bottom of the outer shell. This patented geotextile can carry the potting soil and seedlings together with the nursery after seedling cultivation, avoiding damage to the seedling roots when manually digging them out, increasing the transplant survival rate, facilitating watering, providing shade, improving the seedling success rate, and wrapping the roots for convenient transportation after leaving the nursery. Although the above device solves the above problems, there are still problems such as the seeds being relatively fragile during the seedling process and easily affected by unstable external environments, resulting in poor seed development, and the seed roots being easily damaged during transplanting after seed growth, causing plant death after transplanting. Therefore, a heat preservation device for cold protection and pest and disease prevention for forest seedling cultivation is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a heat preservation device for protecting forest tree seedlings from cold and pests, so as to solve the problem of forest tree seedlings being affected by cold waves and pests.

[0005] To achieve the above objectives, the present invention provides a heat preservation device for frost protection and pest and disease prevention in forest tree seedling cultivation, comprising a culture shell, a sealing mechanism at the top of the culture shell, a torsion spring cover rotatably connected to the outer wall of the culture shell, a recycling mechanism inside the culture shell, and a post-processing mechanism at the bottom of the culture shell. The sealing mechanism includes a sliding cover, a sieve plate, a seed chamber, a water-permeable bag, and a permeable groove. The sliding cover is slidably connected to the top of the culture shell, the sieve plate is fixedly connected to the inner wall of the culture shell, the seed chamber is fixedly connected to the inner wall of the culture shell, the water-permeable bag is slidably connected to the inner wall of the seed chamber, and the permeable groove is opened on the inner wall of the seed chamber.

[0006] In one or more embodiments of the present invention, the sealing mechanism further includes a constant temperature lamp, a vertical material trough, a scraper, and a rotating frame. The constant temperature lamp is fixedly connected to the top inner wall of the sliding cover, the vertical material trough is fixedly connected to the top of the sliding cover, the scraper is slidably connected to the inner wall of the vertical material trough, and the rotating frame is rotatably connected to the inner wall of the vertical material trough.

[0007] In one or more embodiments of the present invention, the sealing mechanism further includes a slotted arc plate, a vertical fixed frame, and a transmission rack. The slotted arc plate is fixedly connected to the outer circumferential surface of the rotating frame, the vertical fixed frame is fixedly connected to the top of the culture shell, and the transmission rack is fixedly connected to the inner wall of the transmission rack. The rotating frame and the transmission rack are driven by gear meshing. Before operation, the seed chamber is filled with soil, apple seeds are placed inside the permeable bag, and then covered with soil. A sliding cover is then pulled to cover the top of the seed chamber, isolating it from the external environment and maintaining a constant temperature inside the cover. This effectively prevents external pathogens from reaching the apple seedlings, addressing the risk of frost damage and disease at its source. Before the sliding cover is applied, a low-concentration balanced NPK fertilizer is added to the vertical trough. Pulling the sliding cover then engages the rotating frame with the transmission rack, causing the frame to rotate. This rotation, in turn, rotates the slotted arc plate, applying the balanced NPK fertilizer to the seed surface. This keeps the soil moist but not waterlogged, promoting seedling growth and enhancing the plant's resistance to disease. Before fertilization, fertilizer is placed on the inner wall of the vertical trough, and then the scraper is pulled to stir the fertilizer mixture, improving the seed's nutrient absorption efficiency.

[0008] In one or more embodiments of the present invention, the recycling mechanism includes a discharge chamber, a connecting rod, a crossflow tube, and a vertical flow tube. The discharge chamber is fixedly connected to the outer wall of the culture shell, the connecting rod is fixedly connected to the bottom of the discharge chamber, the crossflow tube is fixedly connected to the bottom of the connecting rod, and the vertical flow tube is fixedly connected to the inner wall of the crossflow tube.

[0009] In one or more embodiments of the present invention, the recycling mechanism further includes a flow pipe, a torsion spring plate, a first spiral rod, and a moving block. The flow pipe is opened on the outer wall of the vertical flow pipe, the torsion spring plate is rotatably connected to the inner wall of the culture shell, the first spiral rod is fixedly connected to the outer wall of the torsion spring plate, and the moving block is movably connected to the outer circumferential surface of the first spiral rod.

[0010] In one or more embodiments of the present invention, the recycling mechanism further includes a limiting rod, a triangular block, a rotating column, and a vertical moving rod. The limiting rod is fixedly connected to the inner wall of the culture shell, the vertical moving rod is slidably connected to the inner wall of the sieve plate, the triangular block is fixedly connected to the bottom of the vertical moving rod, the rotating column is rotatably connected to the bottom of the triangular block, the rotating column is located on the movement trajectory of the moving block, the moving block is slidably connected to the outer wall of the limiting rod, and the triangular block and the sieve plate are connected by a spring. During the growth of apple seedlings, when nutrients need to be applied, water and fertilizer can be placed inside the feeding chamber. The fertilizer then flows through a connecting rod into the inner wall of the crossflow pipe, then into the interior of multiple vertical flow pipes, and finally into the soil inside the culture shell through the flow pipes on the outer wall of the vertical flow pipes. The nutrients then pass through a permeable trough and a permeable bag to provide nutrients to the growing apple seeds. This avoids the need to open the sliding cover during fertilization, which would disrupt the constant temperature environment inside the device, and avoids direct human contact with the seedlings during watering and fertilization, reducing the possibility of seedling infection by pathogens. Once the seedlings are fully grown... Afterwards, when transplanting the seedlings, open the sliding cover, then rotate the torsion spring plate. The rotation of the torsion spring plate, through the spiral groove on the circumferential surface, drives the moving block to move into the interior of the culture shell under the limit of the limiting rod. During the movement of the moving block, it contacts the rotating column, and then squeezes the rotating column to drive the triangular block to move upward. The upward movement of the triangular block drives the vertical moving rod to move upward, and the upward movement of the vertical moving rod drives the permeable bag to move upward. After the permeable bag moves upward, it pushes out the fully grown apple seedling, which facilitates the manual transplanting of the apple seedlings and avoids damage to the root system of the seedlings during the transplanting process, thus reducing their survival rate.

[0011] In one or more embodiments of the present invention, the post-processing mechanism includes a vertical connecting rod, a transverse sweeping plate, and a transmission extruder. The vertical connecting rod is fixedly connected to the bottom of the moving block, the transverse sweeping plate is fixedly connected to the bottom of the vertical connecting rod, the transmission extruder is fixedly connected to the outer wall of the vertical connecting rod, and the transverse sweeping plate is slidably connected to the inner wall of the culture shell.

[0012] In one or more embodiments of the present invention, the post-processing mechanism further includes a transmission protrusion, a torsion spring closing door, and a second spiral rod. The transmission protrusion is fixedly connected to the outer wall of the transmission extrusion frame, the torsion spring closing door is rotatably connected to the inner wall of the culture shell through a torsion spring, the second spiral rod is rotatably connected to the inner wall of the sliding cover, and the torsion spring closing door is located on the movement trajectory of the transmission protrusion.

[0013] In one or more embodiments of the present invention, the post-processing mechanism further includes a transverse frame and a camera, the transverse frame being movably connected to the inner wall of the sliding cover, the camera being fixedly connected to the bottom of the transverse frame, and the transverse frame being slidably connected to the inner wall of the sliding cover. After the plant cultivation is complete, the moving block moves, driving the vertical connecting rod to move. The vertical connecting rod then moves the horizontal sweeping plate. During the plant's growth, residual water and fertilizer applied from above drips through the gaps in the sieve plate to the bottom of the cultivation shell. The horizontal sweeping plate then continues to move, pushing the settled water and fertilizer residue to the rear of the torsion spring closing door. As the vertical connecting rod pushes the door, it drives the transmission extruder to move. The transmission extruder then moves the transmission protrusion, which contacts the torsion spring closing door, opening it. The residual water and fertilizer inside is then discharged from the cultivation shell, preventing excessive residue from rotting and causing a foul odor. During the apple seed cultivation process, the rotating spiral rod II drives the horizontal moving frame to move under the limit of the sliding cover. The movement of the horizontal moving frame moves the camera, allowing for better recording of the apple seed's growth process without the need for manual observation by opening the sliding cover. This avoids frequent contact between the plant and the outside environment during growth, which could disrupt the constant temperature inside the device and affect the plant's normal growth.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This heat-preserving device for forest tree seedling cultivation, designed for frost and disease prevention, utilizes a rotating frame, sliding cover, slotted arc plate, permeable bag, and seed chamber. Before operation, the seed chamber is filled with soil, apple seeds are placed inside the permeable bag, covered with soil, and then the sliding cover is pulled to cover the top of the seed chamber, isolating it from the external environment and maintaining a constant temperature inside. This effectively prevents external pathogens from approaching the apple seedlings, addressing the risk of frost damage and disease infestation at its source. Pulling the sliding cover engages the rotating frame with a transmission rack, causing the frame to rotate. This rotation, in turn, rotates the slotted arc plate, applying balanced nitrogen, phosphorus, and potassium fertilizer to the seed surface while keeping the soil moist but not waterlogged, promoting seedling growth and enhancing the plant's resistance to subsequent diseases.

[0015] This heat-preserving device for forest tree seedling cultivation, designed for cold and disease prevention, utilizes a combination of triangular blocks, rotating columns, and moving blocks. The moving blocks contact the rotating column during movement, squeezing the column and causing the triangular blocks to move upwards. This upward movement of the triangular blocks then moves the vertical moving rod upwards, which in turn moves the permeable bag upwards. The permeable bag then pushes out the fully grown apple seedlings, facilitating manual transplantation and preventing root damage during transplantation, thus reducing the survival rate. Nutrients flow through the guide rod into the inner wall of the crossflow pipe, then into multiple vertical flow pipes, and finally into the soil inside the culture shell through the flow pipe on the outer wall of the vertical flow pipes. Nutrients then permeate through the permeable trough and permeable bag, providing nutrients to the growing apple seeds. This eliminates the need to open the sliding cover during fertilization, thus maintaining the constant temperature environment inside the device and preventing direct contact between humans and seedlings during watering and fertilization, reducing the possibility of seedling infection by pathogens.

[0016] This heat-preserving device for forest tree seedling cultivation, designed for cold and pest control, works in conjunction with a culture shell, a sieve plate, and a sliding cover. During apple seed cultivation, a rotating spiral rod drives a horizontal moving frame, which moves within the limits of the sliding cover. This movement of the horizontal moving frame moves a camera, allowing for better recording of the apple seed's growth process without the need for manual observation by opening the sliding cover. This avoids frequent contact between the plant and the outside environment, which could disrupt the constant internal temperature and affect the plant's normal growth. During plant growth, residual water and fertilizer applied from above drips through the gaps in the sieve plate to the bottom of the culture shell. The horizontal sweeping plate then pushes the settled residue to the rear of the torsion spring closing door. The vertical connecting rod, in turn, drives a transmission extrusion frame, which in turn moves a transmission protrusion. This protrusion contacts the torsion spring closing door, opening it and allowing the residual water and fertilizer to drain out of the culture shell, preventing excessive residue and rotting within the device.

Detailed Implementation

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-7 As shown, one embodiment of the present invention is: a heat preservation device for cold protection and disease and pest prevention for forest tree seedling cultivation, including a culture shell 1, a sealing mechanism 2 provided on the top of the culture shell 1, a torsion spring cover 3 rotatably connected to the outer wall of the culture shell 1, a recycling mechanism 4 provided inside the culture shell 1, and a post-processing mechanism 5 provided at the bottom of the culture shell 1. The sealing mechanism 2 includes a sliding cover 201, a sieve plate 202, a seed chamber 203, a water-permeable bag 204, and a permeable groove 205. The sliding cover 201 is slidably connected to the top of the culture shell 1, the sieve plate 202 is fixedly connected to the inner wall of the culture shell 1, the seed chamber 203 is fixedly connected to the inner wall of the culture shell 1, the water-permeable bag 204 is slidably connected to the inner wall of the seed chamber 203, and the permeable groove 205 is opened on the inner wall of the seed chamber 203.

[0021] The sealing mechanism 2 also includes a constant temperature lamp 206, a vertical material trough 207, a scraper 208, and a rotating frame 209. The constant temperature lamp 206 is fixedly connected to the top inner wall of the sliding cover 201, the vertical material trough 207 is fixedly connected to the top of the sliding cover 201, the scraper 208 is slidably connected to the inner wall of the vertical material trough 207, and the rotating frame 209 is rotatably connected to the inner wall of the vertical material trough 207.

[0022] The sealing mechanism 2 also includes a slotted arc plate 210, a vertical frame 211, and a transmission rack 212. The slotted arc plate 210 is fixedly connected to the outer circumferential surface of the rotating frame 209, the vertical frame 211 is fixedly connected to the top of the culture shell 1, and the transmission rack 212 is fixedly connected to the inner wall of the transmission rack 212. The rotating frame 209 and the transmission rack 212 are driven by gear meshing. This heat-preserving device for forest tree seedling cultivation, designed for frost protection and disease and pest control, involves first filling the seed chamber 203 with soil before operation. Apple seeds are then placed inside a permeable bag 204, covered with soil, and then the sliding cover 201 is pulled to cover the top of the seed chamber 203, isolating it from the external environment and maintaining a constant temperature inside the sliding cover 201. This effectively prevents external pathogens from approaching the apple seedlings, addressing the risk of frost damage and disease infestation at the source. Pulling the sliding cover 201 engages the rotating frame 209 with the transmission rack 212, causing the frame 209 to rotate. During this rotation, the slotted arc plate 210 rotates, applying balanced nitrogen, phosphorus, and potassium fertilizer to the seed surface, keeping the soil moist but not waterlogged, promoting seedling growth, and enhancing the plant's subsequent resistance to diseases.

[0023] The recycling mechanism 4 includes a discharge chamber 401, a connecting rod 402, a crossflow tube 403, and a vertical flow tube 404. The discharge chamber 401 is fixedly connected to the outer wall of the culture shell 1, the connecting rod 402 is fixedly connected to the bottom of the discharge chamber 401, the crossflow tube 403 is fixedly connected to the bottom of the connecting rod 402, and the vertical flow tube 404 is fixedly connected to the inner wall of the crossflow tube 403.

[0024] The recycling mechanism 4 also includes a flow pipe 405, a torsion spring plate 406, a spiral rod 407, and a moving block 408. The flow pipe 405 is opened on the outer wall of the vertical flow pipe 404. The torsion spring plate 406 is rotatably connected to the inner wall of the culture shell 1. The spiral rod 407 is fixedly connected to the outer wall of the torsion spring plate 406. The moving block 408 is movably connected to the outer circumferential surface of the spiral rod 407.

[0025] The recycling mechanism 4 also includes a limiting rod 409, a triangular block 410, a rotating column 411, and a vertical moving rod 412. The limiting rod 409 is fixedly connected to the inner wall of the culture shell 1. The vertical moving rod 412 is slidably connected to the inner wall of the sieve plate 202. The triangular block 410 is fixedly connected to the bottom of the vertical moving rod 412. The rotating column 411 is rotatably connected to the bottom of the triangular block 410. The rotating column 411 is located on the movement trajectory of the moving block 408. The moving block 408 is slidably connected to the outer wall of the limiting rod 409. The triangular block 410 and the sieve plate 202 are connected by a spring. This heat-preserving device for frost and pest control in forest seedling cultivation involves a moving block 408 that contacts a rotating column 411 during movement. The rotating column 411 is then compressed, causing a triangular block 410 to move upwards. This upward movement of the triangular block 410 moves a vertical moving rod 412 upwards, which in turn moves a permeable bag 204 upwards. The permeable bag 204 then pushes out the fully grown apple seedlings, facilitating manual transplantation and preventing root damage during transplantation, thus reducing the chances of transplant survival. The nutrients flow into the inner wall of the crossflow tube 403 through the guide rod 402, and then into the interior of multiple vertical flow tubes 404. After that, they flow into the soil inside the culture shell 1 through the flow tube 405 on the outer wall of the vertical flow tube 404. Then, the nutrients pass through the permeable groove 205 and then through the permeable bag 204 to provide nutrients for the apple seeds during the growth process. This avoids the need to open the sliding cover 201 when fertilizing, which would disrupt the constant temperature environment inside the device. It also avoids direct contact between the person and the seedlings when watering and fertilizing, reducing the possibility of seedlings being infected with pathogens.

[0026] Working principle: Before operation, the seed chamber 203 is first filled with soil. Then, apple seeds are placed inside the permeable bag 204 and covered with soil. Next, the sliding cover 201 is pulled to cover the top of the seed chamber 203, isolating it from the external environment and maintaining a constant temperature inside the sliding cover 201. This also effectively prevents external pathogens from approaching the apple seedlings, fundamentally addressing the risk of frost damage and disease infestation. Before covering with the sliding cover 201, a low-concentration balanced NPK fertilizer is added to the vertical feed trough 207. Then, the sliding cover 201 is pulled to drive the rotating frame 209 to mesh with the transmission rack 212, thereby causing the rotating frame 209 to rotate. During the rotation of the rotating frame 209, the slotted arc plate 210 is also rotated, thereby applying nitrogen, phosphorus, and potassium balanced water and fertilizer to the seed surface, keeping the soil moist but not waterlogged, promoting seedling growth, and also enhancing the plant's subsequent resistance to diseases. Before fertilization, the fertilizer in the vertical material trough 207 is placed on the inner wall of the vertical material trough 207, and then the scraper plate 208 is pulled to stir the water and fertilizer mixture inside the vertical material trough 207, thereby improving the seed's absorption efficiency of fertilizer nutrients.

[0027] During the growth of apple seedlings, when nutrients need to be applied to the plants, water and fertilizer can be placed inside the feeding chamber 401. The fertilizer then flows through the guide rod 402 into the inner wall of the crossflow pipe 403, and then into the interior of multiple vertical flow pipes 404. Finally, it flows through the flow pipe 405 on the outer wall of the vertical flow pipes 404 into the soil inside the culture shell 1. Nutrients then pass through the permeable trough 205 and the permeable bag 204 to provide nutrients to the growing apple seeds. This avoids the need to open the sliding cover 201 during fertilization, thus preventing disruption of the constant temperature environment inside the device. It also avoids direct contact between humans and seedlings during watering and fertilization, reducing the possibility of seedling infection by pathogens. After the seedlings have been cultivated, they need to be... During transplantation, the sliding cover 201 is opened, and then the torsion spring plate 406 is rotated. The rotation of the torsion spring plate 406 drives the moving block 408 to move into the culture shell 1 under the limit of the limiting rod 409. During the movement, the moving block 408 contacts the rotating column 411, and then squeezes the rotating column 411 to drive the triangular block 410 to move upward. The upward movement of the triangular block 410 drives the vertical moving rod 412 to move upward. The upward movement of the vertical moving rod 412 drives the permeable bag 204 to move upward. After the permeable bag 204 moves upward, it pushes out the fully grown apple seedling, which facilitates the manual transplantation of the apple seedling and avoids damage to the root system of the seedling during the transplantation process, thus reducing its survival rate.

[0028] Please see Figure 1-7 In another embodiment of the present invention, based on the above embodiments, the post-processing mechanism 5 includes a vertical connecting rod 501, a transverse sweeping plate 502, and a transmission extruder 503. The vertical connecting rod 501 is fixedly connected to the bottom of the moving block 408, the transverse sweeping plate 502 is fixedly connected to the bottom of the vertical connecting rod 501, the transmission extruder 503 is fixedly connected to the outer wall of the vertical connecting rod 501, and the transverse sweeping plate 502 is slidably connected to the inner wall of the culture shell 1.

[0029] The post-processing mechanism 5 also includes a transmission protrusion 504, a torsion spring closing door 505, and a second spiral rod 506. The transmission protrusion 504 is fixedly connected to the outer wall of the transmission extrusion frame 503. The torsion spring closing door 505 is rotatably connected to the inner wall of the culture shell 1 through a torsion spring. The second spiral rod 506 is rotatably connected to the inner wall of the sliding cover 201. The torsion spring closing door 505 is located on the movement trajectory of the transmission protrusion 504.

[0030] The post-processing mechanism 5 also includes a transverse frame 507 and a camera 508. The transverse frame 507 is movably connected to the inner wall of the sliding cover 201, and the camera 508 is fixedly connected to the bottom of the transverse frame 507. The transverse frame 507 is slidably connected to the inner wall of the sliding cover 201. This heat preservation device for forest tree seedling cultivation, designed for cold and pest protection, utilizes a rotating spiral rod 506 during apple seed cultivation. This rotates a horizontal moving frame 507, which moves under the constraint of a sliding cover 201. The movement of the horizontal moving frame 507 also moves a camera 508, allowing for better recording of the apple seed's growth process without the need for manual observation by opening the sliding cover 201. This avoids frequent contact between the plant and the external environment during growth, preventing disruption of the device's internal temperature and ensuring normal plant growth. Any residual water or fertilizer applied during the plant's growth process will pass through a sieve. The water drips from the gap in the sluice plate 202 to the bottom of the culture shell 1. Then, the horizontal sweeping plate 502 continues to move, pushing the water and fertilizer residue settled at the bottom to the rear of the torsion spring closing door 505. During the pushing process, the vertical connecting rod 501 drives the transmission extruder 503 to continue moving. The movement of the transmission extruder 503 drives the transmission protrusion 504 to move. The movement of the transmission protrusion 504 contacts the torsion spring closing door 505, opening the torsion spring closing door 505. Subsequently, the water and fertilizer residue inside will also be discharged from the inside of the culture shell 1 as the torsion spring closing door 505 opens, preventing excessive water and fertilizer residue from rotting and smelling bad inside the device.

[0031] Working principle: After the plant cultivation is completed, the moving block 408 moves, driving the vertical connecting rod 501 to move. The vertical connecting rod 501 moves, driving the horizontal sweeping plate 502 to move. During the plant growth process, the water and fertilizer residue applied above will drip through the gaps in the sieve plate 202 to the bottom of the culture shell 1. Then, the horizontal sweeping plate 502 continues to move, pushing the water and fertilizer residue settled at the bottom to the rear of the torsion spring closing door 505. During the pushing process, the vertical connecting rod 501 drives the transmission extruder 503 to continue moving. The movement of the transmission extruder 503 drives the transmission protrusion 504 to move. The movement of the transmission protrusion 504 contacts the torsion spring closing door 505, closing the torsion spring door. Door 505 opens, and the residual water and fertilizer inside will be discharged from the inside of the culture shell 1 as the torsion spring door 505 opens, preventing excessive water and fertilizer residue from rotting and smelling bad inside the device. During the apple seed cultivation process, the rotating spiral rod 506 drives the transverse frame 507 to move under the limit of the sliding cover 201. The movement of the transverse frame 507 drives the camera 508 to move. During the movement of the camera 508, the growth process of the apple seed can be better recorded without opening the sliding cover 201 for manual observation. This avoids the plant from frequently coming into contact with the outside world during the growth process, which would disrupt the constant temperature inside the device and affect the normal growth process of the plant.
