Description

Technical Field

[0001] The invention belongs to the technical field of seedling raising devices, and in particular relates to a forestry seedling raising device with a three-dimensional structure. Background Art

[0002] Seedling cultivation refers to the process of providing suitable growth conditions for plant seeds, cuttings, rhizomes and other reproductive materials through artificial intervention under suitable environmental conditions, so that they can germinate, grow and cultivate into seedlings with certain morphological and physiological characteristics. It is an important link in the plant cultivation process and plays a key role in improving plant survival rate, promoting growth and development, and realizing large-scale planting. It is widely used in afforestation, greening, agricultural production, etc.

[0003] The three-dimensional forestry seedling device is a modern agricultural facility that uses multi-layer cultivation units for seedling cultivation through a vertical space layered design. The seedling space is distributed in multiple layers in the vertical direction through a physical frame, and the light, temperature, humidity, water and fertilizer irrigation in the integrated environmental control system are used to achieve high-density and standardized seedling cultivation. Its core goal is to improve the seedling efficiency per unit area, optimize resource utilization, and adapt to the needs of intensive and factory-based seedling cultivation.

[0004] During use, the existing three-dimensional forestry seedling raising device has a problem that the root space cannot be extended as the seedlings grow, which causes inconsistent development of the root stems of the seedlings in the incubator, affecting the quality of the seedlings. At the same time, the roots and soil of the seedlings are located inside the device, making it easy for the roots of the seedlings to rub against the inner wall of the device during the transplanting process, thereby damaging the roots of the seedlings and affecting the survival rate of the seedlings. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a forestry seedling raising device with a three-dimensional structure.

[0006] The technical solution adopted to solve the above technical problems is: a forestry seedling raising device with a three-dimensional structure is provided, including a support base arranged in a trapezoidal shape, a support frame is provided on the support base, a spray mounting seat is provided on the top of the support frame, a telescopic and adjustable spray irrigation mechanism is provided in the spray mounting seat, rotating shafts are provided on both sides of the support frame, rotating gears are provided on the rotating shafts, and the rotating gears are connected to several seedling raising boxes through transmission chains, an upper seedling raising tank body and a lower seedling raising tank body are provided in the seedling raising box body, and the lower seedling raising tank body is height-adjustable by a lifting mechanism composed of a movable shaft, a rotating gear and an L-shaped gear block, and a lifting clamp is provided on the upper seedling raising tank body, and a telescopic mechanism is provided at the lower end of the outer side of the lifting clamp.

[0007] Furthermore, the spray irrigation mechanism includes a telescopic cylinder, a telescopic rod, a spray water storage seat and a spray head. The telescopic cylinder drives the spray water storage seat to rise and fall through the telescopic rod, and the spray head is arranged corresponding to the upper seedling tank body.

[0008] Through the above technical solution, the telescopic cylinder serves as a power source, and drives the spray water storage seat to perform telescopic movement through the telescopic rod, thereby adjusting the distance between the spray head and the upper seedling tank body to ensure the irrigation effect. The spray head and the upper seedling tank body are set correspondingly, which can achieve precise irrigation of each seedling tank body and improve the efficiency of water resource utilization.

[0009] Furthermore, a water storage tank is fixedly installed on the upper end of the support base near one side of the support frame, and a water pump is fixedly installed at the center of the upper end of the water storage tank. The input end of the water pump is connected to a No. 1 connecting pipe extending into the water storage tank, and the output end of the water pump is connected to a No. 2 connecting pipe extending into the inside of the spray water storage seat.

[0010] Through the above technical solution, the water storage tank is used to store irrigation water. The water pump draws water from the water storage tank through the No. 1 connecting pipe, and then transports the water to the spray water storage seat through the No. 2 connecting pipe to provide water source for the sprinkler head.

[0011] Furthermore, the transmission chain is connected to the seedling raising box through the special-shaped support rod and the triangular support rod. The seedling raising box is provided with a partition plate and a limit mounting plate, and the seedling raising tank is fixed on the limit mounting plate.

[0012] Through the above technical solution, the special-shaped support rod is connected to the triangular support rod through a rotating shaft, and the triangular support rod is fixedly installed on the seedling box. This connection method enables the seedling box to be stably installed on the transmission chain and move with the movement of the transmission chain. At the same time, the design of the rotating shaft also allows the seedling box to rotate at a certain angle when necessary to adapt to different operational requirements.

[0013] Furthermore, the lifting mechanism is driven by a driving motor, and the driving motor drives a rotating gear through a movable shaft and a transmission belt. The rotating gear is engaged with an L-shaped gear block, and the L-shaped gear block is connected to a sealing bottom plate in the lower seedling tank body.

[0014] Through the above technical solution, the drive motor provides power for the lifting mechanism, and transmits power to the rotating gear through the movable shaft and the transmission belt. The rotating gear engages with the L-shaped tooth block. When the rotating gear rotates, it drives the L-shaped tooth block to move up and down. The L-shaped tooth block is connected to the sealed bottom plate inside the lower seedling tank body, thereby realizing the adjustment of the height of the lower seedling tank body. This lifting mechanism has a compact structure and stable operation. It can accurately control the height of the lower seedling tank body to meet the space requirements of different seedlings.

[0015] Furthermore, a driving motor is fixedly installed at the lower end of one side of the seedling box body, the output end of the driving motor is connected to a movable shaft, the outer side walls of the two movable shafts are sleeved with transmission belts, and several limiting sliding grooves are evenly spaced at both ends of the partition plate to facilitate the lifting and lowering of the L-shaped gear blocks.

[0016] Through the above technical solution, the drive motor provides power for the movable shaft, and drives the two movable shafts to rotate synchronously through the transmission belt. The rotating gear on the movable shaft engages with the L-shaped tooth block, thereby realizing the lifting and lowering of the lower seedling tank body. The limiting slide groove opened on the partition plate provides guidance and limiting effects for the lifting and lowering of the L-shaped tooth block, ensuring the stability and accuracy of the lower seedling tank body during the lifting process.

[0017] Furthermore, a square support block is fixedly mounted on the upper end of the support base near the other side of the support frame, a rotating motor is fixedly mounted on the upper end of the square support block, and an output end of the rotating motor is connected to a rotating shaft.

[0018] Through the above technical solution, the square support block provides stable support for the rotating motor, and the rotating motor drives the rotating gear to rotate through the rotating shaft, and then drives the transmission chain to move, making the power transmission of the entire seedling device more stable and reliable, ensuring the circular movement of the seedling box and the smooth progress of the seedling work.

[0019] Furthermore, a plurality of inner telescopic rings are evenly spaced around the lower end of the outer wall of the pull-tab ring, and a plurality of outer connecting rings are provided at the lower end of the inner telescopic rings. The inner telescopic rings can be telescopically movable within the outer connecting rings, and a bottom limiting ring is provided at the lower end of the outer connecting rings.

[0020] Through the above technical scheme, the inner telescopic ring, the outer connecting ring and the bottom limiting ring together constitute the telescopic mechanism of the pulling clamp ring. The inner telescopic ring can perform telescopic movement in the outer connecting ring to adapt to upper seedling tanks of different heights. The bottom limiting ring is used to limit the telescopic range of the inner telescopic ring to prevent it from being damaged due to excessive expansion and contraction. At the same time, after the seedlings are completed, the seedlings in the seedling tank can be promptly taken out through the pulling clamp ring, avoiding damage to the roots of the seedlings.

[0021] Furthermore, annular grooves are evenly spaced around the inner side of the upper seedling raising tank body to facilitate the telescopic movement of the inner telescopic ring. A sealing bottom plate is installed on the inner side of the lower seedling raising tank body for lifting and lowering, and an L-shaped tooth block is fixedly installed at the center of the lower end of the sealing bottom plate.

[0022] Through the above technical solution, the annular groove opened on the inner side of the upper seedling tank body provides space for the telescopic movement of the inner telescopic ring, ensuring the close fit between the lifting ring and the upper seedling tank body. The sealing bottom plate installed on the inner side of the lower seedling tank body for lifting and lowering is engaged with the rotating gear through the L-shaped tooth block, thereby realizing the lifting and lowering adjustment of the lower seedling tank body. The design of the sealing bottom plate can prevent moisture and soil leakage, maintain the stability of the seedling environment, and at the same time, ensure that the roots of the seedlings have sufficient growth space to enable them to grow during the cultivation period, thereby avoiding the situation where the development progress of the roots of the seedlings is inconsistent and affects the quality of the seedlings.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention is provided with a movable shaft, a rotating gear and an L-shaped gear block and a sealing bottom plate at the inner bottom of the lower seedling tank body. During the seedling cultivation process, as the seedlings grow, the internal space of the lower seedling tank body can be adjusted up and down, thereby ensuring the extension of the seedling root space, thereby avoiding the occurrence of inconsistent development progress of the seedling roots in the lower seedling tank body and the upper seedling tank body, and further improving the seedling quality; (2) The present invention can flexibly adapt to upper seedling tanks of different sizes by providing a telescopic mechanism consisting of an inner telescopic ring, an outer connecting ring and a bottom limiting ring on the outer side wall of the lifting clamp ring. The inner telescopic ring can perform telescopic movement within the outer connecting ring, and the telescopic range is limited by the bottom limiting ring, thereby ensuring a close fit between the lifting clamp ring and the upper seedling tank. When the seedlings need to be transplanted after being cultivated to a certain stage, the height of the lower seedling tank can be adjusted to facilitate the staff to take the seedlings out of the seedling tank, thereby reducing damage to the seedling roots during the transplanting process and improving the survival rate of the seedlings. (3) The present invention can flexibly adjust the position of the spray water storage seat and the spray head by providing a telescopic cylinder inside the spray mounting seat, ensuring that accurate watering can be achieved regardless of the position of the seedling tank body, ensuring that each seedling can be evenly irrigated, and improving the survival rate and growth quality of the seedlings.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figure 1-7As shown, the forestry seedling raising device of this embodiment adopts a three-dimensional structure. The trapezoidal support base 1 can provide a stable support foundation, enhance the stability of the entire seedling raising device when placed, and reduce the risk of the device tilting or tipping over due to external force. The support frame 2 serves as the main supporting structure of the entire device and plays the role of connecting the support base 1 with the upper components to ensure that the upper spray mounting seat 5, seedling box body 9 and other components can be firmly installed. The retractable adjustable spray irrigation mechanism on the spray mounting seat 5 can be independently controlled according to the actual height and position of the seedling tank body, and each spray head 52 is independently controlled. At the same time, each spray head 52 is installed with a rotary joint to flexibly adjust the spraying height and angle to achieve precise watering and ensure that each seedling can be evenly irrigated. The transmission system composed of the rotating shaft 62, the rotating gear 63 and the transmission chain 64 can drive the seedling box body 9 to rotate, and the transmission The movable chain 64 adopts the design of adjusting bolts to avoid the seedling box 9 from tilting due to chain relaxation, which is convenient for management and operation of seedling tanks in different positions, and ensures that the seedlings can be watered, fertilized, and the growth of the seedlings can be checked in time and effectively, thereby improving work efficiency. The upper seedling tank 10 and the lower seedling tank 101 are arranged in the seedling box 9 to form a three-dimensional seedling space, effectively improving space utilization. The lifting mechanism composed of the movable shaft 8, the rotating gear 81 and the L-shaped tooth block 82 can realize the lifting and lowering of the lower seedling tank 101, which is convenient for transplanting the seedlings in the lower seedling tank 101, changing the soil, etc. The lifting clamp 11 and the telescopic mechanism on its outer side are convenient for lifting and transporting the seedling tank. The telescopic mechanism can adjust the length according to actual needs to adapt to different transport scenarios. At the same time, it plays a buffering and protective role in the lifting process to avoid damage to the seedling tank. The telescopic cylinder 51 can flexibly adjust the height of the spray water storage seat by accurately controlling the telescopic length of the telescopic rod, thereby changing the position of the spray head 52, so that whether the upper seedling tank body 10 is in the initial position or at different heights during the rotation of the seedling box body 9, the spray head 52 can accurately aim at the center position of the upper seedling tank body 10 for spraying, thereby ensuring the accuracy and uniformity of water sprinkling. The spray water storage seat is used to store a certain amount of water, which plays a role in buffering and stabilizing the water flow during the spraying process, avoiding uneven water discharge from the spray head 52 due to unstable water supply from the water pump 4, and ensuring that the seedlings can be irrigated continuously and stably; The water storage tank 3 is used to store a large amount of water for seedling cultivation, which can meet the irrigation needs of the seedling cultivation device within a certain period of time, reduce the trouble of frequent water addition, and is particularly suitable for large-scale forestry seedling cultivation scenarios. The water pump 4 serves as the power source of the entire water supply system, draws water from the water storage tank 3 through the No. 1 connecting pipe, and transports the water to the spray water storage seat through the No. 2 connecting pipe. By controlling the power and working time of the water pump 4, the water supply flow and pressure can be adjusted to meet the water needs of seedlings at different growth stages. At the same time, the water storage tank 3 and the water pump 4 are installed on the side of the support base 1 close to the support frame 2, and the spatial structure of the device is reasonably arranged, making the pipeline connection of the entire device more compact, reducing the water flow resistance and energy loss caused by excessively long pipelines; The unique shape design of the special-shaped bracket rod 7 enables it to provide a more stable support and connection effect when connecting the transmission chain 64 and the seedling box 9. Through the cooperation of the rotating shaft and the triangular bracket rod, the seedling box 9 can maintain a relatively stable posture during the rotation of the transmission chain 64, avoiding adverse effects on the growth of seedlings due to excessive shaking. The triangular bracket rod utilizes the stability principle of the triangle to further enhance the supporting strength of the seedling box 9. Even when more seedling tanks are placed in the seedling box 9 or other operations are performed, it can ensure that the seedling box 9 is stable and does not shake. At the same time, it is also convenient for disassembly and installation of the seedling box 9, and it is convenient to perform separate maintenance or replacement of the seedling box 9 when needed. The partition plate 91 divides the interior of the seedling box 9 into two relatively independent spaces, the upper and lower seedling tanks 10 and the lower seedling tanks 101, so that the upper seedling tank 10 and the lower seedling tank 101 can be placed in order to avoid mutual interference, and it also helps to reasonably plan the seedling space. The limiting mounting plate 92 plays a limiting and fixing role for the upper seedling tank 10 placed at the upper end, preventing the upper seedling tank 10 from shifting or tipping over during the rotation of the seedling box 9, thereby ensuring the stability of the seedling cultivation environment. By arranging the upper seedling tanks 10 at equal intervals, it can be ensured that each seedling has enough growth space, and it is convenient to carry out unified management and maintenance operations, thereby improving the efficiency and quality of seedling cultivation. The driving motor provides a power source for the rotation of the movable shaft 8. By controlling the speed and direction of the driving motor, the rotation of the movable shaft 8 can be accurately controlled, thereby realizing accurate adjustment of the lifting and lowering of the lower seedling tank body 101. The setting of the transmission belt enables the two movable shafts 8 to rotate synchronously, ensuring the stability of the lower seedling tank body 101 during the lifting process to avoid tilting or jamming. The limiting slide groove 911 provided on the partition plate 91 provides a guide and limiting effect for the lifting and lowering of the L-shaped tooth block 82, ensuring that the L-shaped tooth block 82 always maintains vertical movement during the lifting process to prevent it from deflecting, thereby ensuring that the lower seedling tank body 101 can be accurately lifted to the predetermined position, facilitating various seedling raising operations; The square support block 6 plays the role of firmly supporting the rotating motor 61, ensuring that the rotating motor 61 remains stable during operation and reducing the impact of motor vibration on the entire device. The rotating motor 61 serves as the core power component of the entire device to drive the seedling box 9 to rotate. The rotating shaft 62 connected to its output end drives the rotating gear 63 and the transmission chain 64 to move, thereby realizing the rotation of the seedling box 9. By adjusting the speed and rotation direction of the rotating motor 61, the rotation speed and angle of the seedling box 9 can be controlled to meet different seedling management needs. When carrying out comprehensive irrigation, the rotation speed can be appropriately accelerated to ensure that each seedling tank can be irrigated in time. When checking the growth of seedlings in a specific position, the rotation angle can be accurately controlled to rotate the target seedling box 9 to a position that is convenient for observation. The inner telescopic ring 111, the outer connecting ring 112 and the bottom limiting ring 113 together constitute the telescopic buffer structure of the lifting clamp ring 11. When the seedling tank body is lifted, the inner telescopic ring 111 can be expanded and contracted according to the pulling force and actual needs, which plays a role of buffering and shock absorption, reduces the impact force on the seedling tank body during the pulling process, and protects the seedlings from damage. The outer connecting ring 112 cooperates with the inner telescopic ring 111 to enhance the stability and reliability of the entire telescopic structure, and also facilitates the telescopic movement of the inner telescopic ring 111. The bottom limiting ring 113 is used to limit the telescopic range of the inner telescopic ring 111 and the outer connecting ring 112, to prevent structural damage caused by excessive expansion and contraction during the pulling process, and ensure that the lifting clamp ring 11 can be used safely and stably. In addition, this telescopic structure also enables the lifting clamp ring 11 to adapt to seedling tanks of different sizes and weights, thereby improving the versatility of the device. The annular groove provided on the inner side of the upper seedling raising tank body 10 provides a movable space for the inner telescopic ring 111, so that the inner telescopic ring 111 will not interfere with the inner wall of the upper seedling raising tank body 10 during the extension and contraction process, thereby ensuring the flexibility and stability of the connection between the lifting ring 11 and the upper seedling raising tank body 10, and the sealing bottom plate on the inner side of the lower seedling raising tank body 101 can effectively prevent soil and moisture from leaking from the bottom of the lower seedling raising tank body 101, thereby keeping the seedling raising environment clean and stable. At the same time, the sealing bottom plate is fixedly connected to the L-shaped gear block 82, and under the action of the lifting mechanism composed of the movable shaft 8, the rotating gear 81 and the L-shaped gear block 82, the sealing bottom plate drives the lower seedling raising tank body 101 to perform the lifting movement, and the outer wall of the sealing bottom plate contains a sealing ring, which realizes the convenient operation of the lower seedling raising tank body 101 and meets the needs of managing and cultivating seedlings at different growth stages during the forestry seedling raising process; A mechanical interlocking device is provided between the rotating motor 61 and the driving motor so that both cannot be powered on at the same time, and the transmission chain 64 is additionally provided with a tensioning wheel and a clutch. When the rotating motor 61 is working, the chain is automatically compressed, and when the driving motor is working, the clutch is disengaged to prevent the chain from passively rotating.

[0028] The working principle of this embodiment is as follows: First, the square support block 6 at the upper end of the support base 1 is fixedly installed with a rotating motor 61, and the rotating shaft 62 connected to its output end passes through the support frame 2. The rotating gear 63 at the end is engaged with the transmission chain 64, and the transmission chain 64 is connected to the triangular support rod through the special-shaped support rod 7 and the rotating shaft, thereby fixing the seedling box 9. When the rotating motor 61 is started, it drives the rotating shaft 62 and the rotating gear 63 to rotate, driving the transmission chain 64 to circulate, so that the seedling box 9 rotates around the support frame 2, which is convenient for operating the seedling tanks at different positions; Secondly, the output end of the driving motor at the lower end of the inner side of the seedling box body 9 is connected to the movable shaft 8, and the two movable shafts 8 rotate synchronously through the transmission belt, and the rotating gear 81 on the outer side thereof is meshed with the L-shaped tooth block 82, and the upper end of the L-shaped tooth block 82 is connected to the sealing bottom plate in the lower seedling tank body 101. When the driving motor is working, it drives the movable shaft 8 and the rotating gear 81 to rotate, so that the L-shaped tooth block 82 drives the sealing bottom plate to rise and fall in the lower seedling tank body 101, and adjusts the internal space of the lower seedling tank body 101 to meet the growth demand of the seedling roots. At the same time, the outer side of the pulling card ring 11 at the upper end of the upper seedling tank body 10 is provided with a telescopic mechanism consisting of an inner telescopic ring 111, an outer connecting ring 112 and a bottom limiting ring 113. The inner telescopic ring 111 can be telescoped in the outer connecting ring 112, and the bottom limiting ring 113 limits the telescopic range, which is convenient for taking out seedlings when transplanting; Finally, the water storage tank 3 on the supporting base 1 is connected to the input end of the water pump 4 through the No. 1 connecting pipe, and the output end of the water pump 4 is connected to the spraying water storage seat in the spraying mounting seat 5 through the No. 2 connecting pipe. The telescopic rod at the output end of the telescopic cylinder 51 in the spraying mounting seat 5 drives the spraying water storage seat to rise and fall, and the spray head 52 at the lower end corresponds to the upper seedling tank body 10. When irrigation is needed, the water pump 4 pumps water from the water storage tank 3 into the spraying water storage seat, and the telescopic cylinder 51 adjusts the position of the spray head 52 to achieve precise watering of each upper seedling tank body 10.
