Description

Technical Field

[0001] This invention belongs to the field of rice cultivation technology, and particularly relates to a rice cultivation device. Background Technology

[0002] Rice is a major global food crop, and its safe production is crucial to national welfare and people's livelihood. However, lodging in rice has long constrained yield and quality, leading to weakened photosynthesis, insufficient grain filling, and significant yield reduction. It can also cause sprouting and mold on the panicles, and increase harvesting costs.

[0003] Currently, large-scale seedling raising generally uses seedling trays. Existing technologies mainly focus on the precise control of environmental factors such as light, temperature, water, and fertilizer. Although this improves the uniformity and survival rate of seedlings, it generally neglects the training of stress resistance. Traditional seedling trays and intelligent rice planting equipment are completely static and lack a mechanism to simulate natural wind to mechanically stimulate the seedlings. This results in seedlings cultivated under "over-protection" having a neat appearance, but with fragile stems and insufficient root toughness, posing a hidden danger of "inherent deficiencies". Once transplanted to the field and encountering wind and rain, their lodging resistance is far lower than that of seedlings that have been tempered by natural wind, making them very prone to lodging and ultimately leading to reduced yield.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings, are intended to cover non-exclusive inclusion. The terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a rice planting device, such as... Figure 1-15 As shown, the rice planting device includes: a base 1 and a base 2 disposed on the base 1; a mounting frame 3 fixedly mounted on the base 2; several seedling trays 4 slidably mounted on the mounting frame 3 for rice seedling cultivation; a support frame 5 fixedly mounted on the base 1; a set of fans 6 disposed on the support frame 5 for providing a gentle breeze environment to the seedlings; and a shaking mechanism disposed on the base 1 for driving the base 2 and the seedling trays 4 to shake, thereby strengthening the flexural strength of the seedling stem base and root system. The shaking mechanism includes: a protective frame 17 fixedly mounted on the top of the base 1; and a rotating mechanism mounted on the protective frame. The protective frame 17 includes a rotating rod 7 and a rotating rod 18; a connecting support rod 8 fixedly sleeved on the rotating rod 7; a support plate 9 installed inside the protective frame 17; an active support rod 10 rotatably installed on the support plate 9; a connecting support rod 11 hinged to the bottom of the base 2, the connecting support rod 11 being hinged to the connecting support rod 8 and the active support rod 10 respectively; a motor 12 installed on one side of the support plate 9 for driving the active support rod 10 to rotate, the output shaft of the motor 12 coupling being fixedly connected to the rotating shaft of the active support rod 10; and an adjustment mechanism provided on the support frame 5 for adjusting the position of the fan 6.

[0022] In this embodiment, rice seeds are first placed in seedling tray 4 for germination and initial growth. Seedling tray 4 is slidably installed on the slide rail of mounting frame 3 for easy batch management and handling. After installation, L-shaped baffle 28 is placed on base 2 to abut one side of seedling tray 4 to prevent slippage. Tighten the screw rod 29 to fix L-shaped baffle 28 on base 2 to ensure that seedling tray 4 remains stable during subsequent shaking. When the seedlings are 5 to 8 centimeters tall, the lodging resistance training program can be started through the control system. The training frequency can be set to start once per hour, lasting 10 minutes each time, or the number of starts and duration can be adjusted according to actual needs. When the shaking mechanism is working, the control system first starts the motor 12, whose output shaft drives the active support rod 10 to rotate. The active support rod 10 drives one end of the connecting support rod 11 to make a circular motion through the hinge point. The other end of the connecting support rod 11 is hinged to the connecting support rod 8, causing the connecting support rod 8 to drive the rotating rod 7 to swing left and right. The movement of the connecting support rod 11 causes the base 2 to swing up and down in an irregular circular motion, thereby causing the seedlings in the mounting frame 3 and the seedling tray 4 to shake at a low frequency. This low-frequency shaking can effectively exercise the base of the seedling stem and root system. To avoid damage caused by excessive frequency, the fan 6 on the support frame 5 is turned on to blow a gentle breeze onto the swaying seedlings, simulating a natural environment. Through the setting of the fan 6 and the swaying mechanism, the lodging resistance training of rice seedlings is automated. At the same time, the swaying mechanism simulates the mechanical stress of natural wind and rain on the seedlings, effectively training the bending resistance of the seedling stem base and root system. The fan 6 provides a controllable gentle breeze environment. The two work together to significantly improve the robustness and lodging resistance of the seedlings, laying the foundation for high and stable yields.

[0023] In a further preferred embodiment of the present invention, a sprocket 13 is fitted on both the active support rod 10 and the rotating rod 18, and a chain 14 is fitted on both sprockets 13. The chain 14 meshes with the two sprockets 13. A sprocket 15 is fixedly fitted on each of the rotating rods 18, and a chain 16 is fitted on the sprockets 15. The chain 16 meshes with the sprockets 15. The sprockets 13, chain 14, sprockets 15, and chain 16 are used to drive a set of swaying mechanisms to operate synchronously.

[0024] In this embodiment, when motor 12 drives the active support rod 10 to rotate, the sprocket 13 fixed on it transmits power to the sprocket 13 on the rotating rod 18 via chain 14, causing the two rotating rods to rotate synchronously. The two rotating rods 18 are linked together through sprocket 15 and chain 16, thereby ensuring that a set of swaying mechanisms operates synchronously, making the swaying of the base 2 stable and consistent, and avoiding damage to the seedlings due to uneven force. By adopting the transmission scheme of sprocket 13, chain 14, sprocket 15, and chain 16, it is ensured that multiple sets of swaying mechanisms driven by a single motor can operate synchronously, thereby ensuring that the base 2 is subjected to uniform force and sways smoothly and consistently, avoiding torsional stress caused by asynchrony, and thus preventing damage to the mechanism.

[0025] In a further preferred embodiment of the present invention, the support frame 5 is composed of a plurality of legs, a support frame and a plurality of hydraulic cylinders 19. The plurality of legs are all fixedly mounted on the base 1, and the plurality of hydraulic cylinders 19 are respectively mounted on the plurality of legs for adjusting the height of the fan 6. The support frame is fixedly mounted on the plurality of hydraulic cylinders 19.

[0026] In this embodiment, as the seedlings grow, their height increases continuously. By controlling the extension and retraction of the hydraulic cylinder 19 through the control system, the support frame can be lifted as a whole, thereby adjusting the height of the fan 6 installed on it, ensuring that the fan 6 is always in the best blowing position, which can effectively blow on the seedlings without damaging them due to being too close. While adjusting the height of the fan 6, the telescopic rod 54 will retract or extend along with the height of the support frame. The output rod of the telescopic rod 54 is rectangular, which facilitates the transmission of rotational force. The height of the support frame 5 is adjusted by the lifting structure composed of hydraulic cylinder 19. The blowing position of the fan 6 can be flexibly adjusted according to the actual growth height of the seedlings, ensuring that the wind force can effectively act on the seedlings at different growth stages, while avoiding mechanical damage that may be caused by the fan 6 being too low.

[0027] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a set of one-way screws 20 rotatably mounted on the support frame 5; a slider 21 threaded onto the one-way screws 20 for driving the fan 6 to move; sprockets 22 respectively fixedly mounted on the set of one-way screws 20; a chain 23 mounted on the set of sprockets 22; a mounting block 24 fixedly mounted on the support frame 5; a motor 25 fixedly mounted on the mounting block 24 for driving the set of one-way screws 20 to rotate; and bevel gears 26 respectively fixedly mounted on the output shaft of the coupling between any one-way screw 20 and the motor 25, wherein the set of bevel gears 26 mesh with each other.

[0028] In this embodiment, when it is necessary to move the fan 6 horizontally to change its blowing position, the second motor 25 is started. The second motor 25 drives one of the one-way screws 20 to rotate through the bevel gear 26 meshing with the one-way screw 20 on its output shaft. The one-way screw 20 drives the other one-way screw 20 to rotate synchronously through the sprocket 22 and chain 23 on it. The slider 21 moves horizontally accordingly, thereby driving the fan 6 on it to move together, realizing the horizontal position adjustment of the fan 6. By reversing the direction of the bevel gear 26 and using the sprocket 22 and chain 23 to realize the synchronous rotation of the two one-way screws 20, the slider 21 is driven to move, realizing the precise, stable and synchronous adjustment of the horizontal position of the fan 6, and expanding the effective range of a single fan.

[0029] In a further preferred embodiment of the present invention, the base 2 is provided with an L-shaped baffle 28 for limiting the seedling tray 4 within the mounting frame 3. The L-shaped baffle 28 is in contact with one side of the seedling tray 4, and a screw rod 29 is threadedly installed on the L-shaped baffle 28. The screw rod 29 is threadedly connected to the base 2, and the screw rod 29 is used to fix the L-shaped baffle 28 on the base 2.

[0030] In this embodiment, after the seedling tray 4 is installed into the mounting frame 3, the L-shaped baffle 28 is placed on the base 2, with its side contacting the end of the seedling tray 4 to prevent all seedling trays 4 from sliding out of the slide rail of the mounting frame 3 during shaking. Then, the screw rod 29 is tightened to make it threaded and secure to the base 2, thereby firmly fixing the L-shaped baffle 28 and ensuring reliable limiting. Through the cooperation of the L-shaped baffle 28 and the screw rod 29, the seedling tray 4 can be effectively prevented from accidentally falling out of the slide rail of the mounting frame 3 during frequent shaking, ensuring the safety and continuity of production operations. At the same time, it is convenient to load and unload, and facilitates the picking, placing and managing of the seedling tray 4.

[0031] In a further preferred embodiment of the present invention, a protective cover 59 is fixedly installed at the bottom of the base 2, the protective cover 59 covers the protective frame 17, and a guide plate 60 for guiding the slider 21 is fixedly installed on the support frame 5, the guide plate 60 slidingly contacts the top of the slider 21.

[0032] In this embodiment, the protective cover 59 covers the entire protective frame 17 and the internal transmission components such as chains and sprockets, effectively preventing the intrusion of foreign objects or accidental contact by the human body during operation, thus improving safety. The guide plate 60 slides in contact with the top of the slider 21, providing auxiliary support and guidance for the horizontal movement of the slider 21, making its operation more stable.

[0033] In a further preferred embodiment of the present invention, a protective cover for protecting the chain 23 and the bevel gear 26 is fixedly installed on one side of the support frame 5, and the protective cover covers the chain 23 and the bevel gear 26.

[0034] In this embodiment, the protective cover installed on one side of the support frame 5 encloses the transmission components such as chain 23 and bevel gear 26, serving to prevent dust, foreign objects from getting stuck, and provide safety protection.

[0035] In a further preferred embodiment of the present invention, a rack 30 is fixedly installed on one side of the support frame 5, a connecting block is rotatably installed on the round rod at the top of the fan 6 housing, a connecting gear 31 is fixedly installed on the round rod, the connecting gear 31 meshes with the rack 30 to adjust the airflow direction of the fan 6, a connecting frame 32 is fixedly installed on the connecting block, and a rubber pad 33 is provided at the bottom of the connecting frame 32, the rubber pad 33 being in close contact with the top of the connecting gear 31.

[0036] In this embodiment, when the adjustment mechanism drives the slider 21 to move the fan 6 horizontally, the connecting gear 31 fixed on the round rod of the fan 6 housing moves accordingly. When the connecting gear 31 meshes with the rack 30, the rack 30 forces the connecting gear 31 to rotate, thereby driving the entire fan 6 to rotate around the round rod, realizing automatic adjustment of the wind direction. The rubber pad 33 always maintains frictional contact with the top of the connecting gear 31, providing damping and preventing the fan 6 from rotating freely due to vibration in the non-adjusted state. By automatically adjusting the fan direction through the principle of the meshing of the connecting gear 31 and the rack 30, the automatic adjustment of the wind direction is realized. No additional power or control is required. The wind direction can be switched 180° during the horizontal movement. At the same time, the rubber pad 33 provides frictional damping, which initially restricts the free rotation of the fan 6 and enhances stability.

[0037] In a further preferred embodiment of the present invention, a support plate 34 is fixedly installed on one side of the connecting frame 32, and a plurality of guide rods 35 are slidably installed on the support plate 34. A locking block 36 for limiting the connecting gear 31 is fixedly installed at one end of the guide rod 35. The locking block 36 engages with the teeth of the connecting gear 31. A spring 37 for resetting the locking block 36 is sleeved on the guide rod 35. The two ends of the spring 37 are fixedly connected to the locking block 36 and the support plate 34, respectively.

[0038] In this embodiment, when the connecting gear 31 rotates due to meshing with the rack 30, its teeth will press against the inclined surface of the locking block 36, overcoming the elastic force of the spring 37 and pushing the locking block 36 back. When the adjustment is completed and the connecting gear 31 disengages from the rack 30 and stops rotating, the spring 37 pushes the locking block 36 to re-engage between the teeth of the connecting gear 31, locking it to prevent the fan 6 from rotating and fixing the airflow direction. By using the spring-reset locking block 36 to lock the connecting gear 31, a mechanical self-locking function is provided. When the airflow direction is adjusted, the locking block 36 can automatically engage with the gear teeth, firmly locking the fan angle and preventing it from deflecting due to wind or vibration, thus ensuring the accuracy and reliability of the blowing direction.

[0039] In a further preferred embodiment of the present invention, the guide rods 35 are arranged in a triangular pattern, and both sides of the locking block 36 are inclined surfaces.

[0040] In this embodiment, the guide rods 35 are arranged in a triangular pattern to ensure that the several locking blocks 36 are subjected to balanced force, move smoothly, and do not deviate. At the same time, the inclined surface design on both sides of the locking block 36 allows it to be smoothly pushed back and popped out when the gear is rotating in both directions, thus achieving the locking function.

[0041] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, each of the group of sliders 21 is provided with a moving mechanism for driving the fan 6 to move horizontally. The moving mechanism includes: a connecting frame 38 respectively installed on the group of sliders 21, and a one-way screw 39 rotatably installed on the connecting frame 38 for driving the fan 6 to move left and right to blow air on the seedlings; a slider 40 threaded on the one-way screw 39; a sprocket 41 fixedly installed on the group of one-way screws 39, and a chain 42 installed on the group of sprockets 41; an L-shaped plate 43 installed on one side of the support frame 5, and connecting gears 44 are provided on both the L-shaped plate 43 and the group of one-way screws 39, and several connecting gears 44 mesh with each other.

[0042] In this embodiment, while the swaying mechanism is running, the rotational force of the rotating rod 18 is transmitted to the one-way screw 39 through the linkage unit, driving the fan 6 to move horizontally reciprocally, expanding the airflow coverage. The rotating rod 18 transmits power to the differential gear 47 in the mounting box 45 through the sprocket 56 and the chain 57. After the differential gear set (including differential gear 47 and differential gear 48) adjusts its speed, it acts on the inclined frame 492 through the L-shaped rod 495 and the support wheel 496. The inclined frame 492 pushes the rack 491 to slide along the guide block 493, driving the connecting gear 494 to rotate. The connecting gear 494 drives the driving gear 50 and the driven gear 51 to rotate. The rotation transmits power to the telescopic rod 54 and the linkage rod 53 through the bevel gear 55. The bevel gear 55 at the top of the linkage rod 53 meshes with the connecting gear 44, driving the one-way screw 39 to rotate. The one-way screw 39 drives the slider 40 and the fan 6 to move back and forth, achieving uniform airflow to multiple seedling trays 4. The one-way screw 39, sprocket 41 and chain 42 enable the synchronous movement of multiple fans, and the meshing connecting gear 44 ensures synchronous transmission. This allows the fans to perform a wide-range reciprocating scanning airflow at a fixed height, greatly increasing the airflow coverage of a single fan, making the seedlings receive airflow more evenly, and improving the hardening effect.

[0043] In another embodiment of the present invention, an installation box 45 is fixedly installed on the base 1, and an installation plate 46 is fixedly installed inside the installation box 45. The installation box 45 is provided with a linkage unit for transmitting the rotational force of the rotating rod 18 to the one-way screw 39. The linkage unit includes a differential gear set disposed in the installation box 45, a reciprocating mechanism 49 disposed on one side of the installation plate 46, and a transmission mechanism disposed on the other side of the installation plate 46.

[0044] In this embodiment, the linkage unit is set inside the mounting box 45. Its function is to extract the rotational power of the rotating rod 18 in the swaying mechanism, and after the speed is adjusted by the differential gear set, it is converted into reciprocating motion by the reciprocating mechanism 49, and then transmitted to the one-way screw 39 of the moving mechanism through the transmission mechanism to drive the fan 6 to move left and right. The mounting plate 46 is used to install and support the various components. By extracting the power of the swaying mechanism to drive the movement of the fan 6, the reuse of power is realized. Only one motor 12 is used to drive the two functions of swaying and horizontal movement at the same time, saving the cost of adding an extra motor and reducing energy consumption.

[0045] In another embodiment of the present invention, the differential gear set includes: a first differential gear 47 respectively installed on one end of the second rotating rod 18 and on one side of the inner wall of the mounting box 45, and a set of the first differential gears 47 meshing with each other; a second differential gear 48 respectively provided on one side of the inner wall of the mounting box 45 and on the rotating shaft of the first differential gear 47 located in the mounting box 45, and a set of the second differential gears 48 meshing with each other.

[0046] In this embodiment, the differential gear set consists of two sets of meshing differential gear 47 and differential gear 48. By selecting gears with different numbers of teeth, the output speed and torque can be changed to meet the input speed requirements of the reciprocating mechanism 49.

[0047] In another embodiment of the present invention, the reciprocating mechanism 49 includes: a guide block 493 fixedly installed on one side of the mounting plate 46; a rack 491 slidably installed on the guide block 493; an inclined frame 492 fixedly installed on one end of the rack 491; a connecting gear 494 rotatably installed on one side of the mounting plate 46 and meshing with the rack 491; and an L-shaped rod 495 fixedly installed on the shaft of a differential gear 48 located on one side of the inner wall of the connecting box for transmitting rotational force to the inclined frame 492, wherein a support wheel 496 is installed at one end of the L-shaped rod 495, and the support wheel 496 is located inside the inclined frame 492 and in contact with the inner wall of the inclined frame 492.

[0048] In this embodiment, the output power of the differential gear set drives the L-shaped rod 495 to rotate, and the support wheel 496 at the end of the L-shaped rod 495 rolls inside the inclined frame 492. Due to the action of the inner wall contour of the inclined frame 492, the circular motion of the support wheel 496 is converted into the linear reciprocating motion of the inclined frame 492 and the rack 491 fixed thereto. The rack 491 then drives the connecting gear 494 meshing with it to perform alternating forward and reverse rotational motion.

[0049] In another embodiment of the present invention, the transmission mechanism includes: a driving gear 50 and a driven gear 51, both disposed on the other side of the mounting plate 46, wherein the driving gear 50 is fixedly connected to the rotating shaft of the connecting gear 494 and the driving gear 50 and the driven gear 51 mesh with each other; a protective box 52 mounted on one side of the L-shaped plate 43; a linkage rod 53 rotatably mounted on the bottom of the protective box 52, wherein a telescopic rod 54 is fixedly mounted on the bottom end of the linkage rod 53 and the rotating shaft at the bottom of the telescopic rod 54 is rotatably connected to the mounting box 45; two sets of bevel gears 55 respectively fixedly sleeved on the rotating shaft of the telescopic rod 54, the top end of the linkage rod 53, the rotating shaft of the driven gear 51, and the rotating shaft of the connecting gear 44 located on the L-shaped plate 43, wherein the two sets of bevel gears 55 mesh with each other; and sprockets 56 respectively fixedly sleeved on the rotating shafts of the rotating rod 18 and the differential gear 47, wherein a chain 57 is sleeved on one set of sprockets 56.

[0050] In this embodiment, the shaft of the connecting gear 3 494 drives the driving gear 50 to rotate, and the driving gear 50 drives the driven gear 51 that meshes with it to rotate. The driven gear 51 changes the direction of power through a set of bevel gears 2 55, and then transmits it upward through the telescopic rod 54 and the linkage rod 53. Another set of bevel gears 2 55 at the top of the linkage rod 53 changes the direction of power again, drives the connecting gear 2 44 to rotate, and finally drives the one-way screw 2 39 to rotate. The sprocket 5 56 and the chain 5 57 are used to introduce the power of the rotating rod 2 18 into the differential gear 1 47 in the mounting box 45.

[0051] In another embodiment of the present invention, a protective cylinder 58 is fixedly installed at the bottom of the mounting block 24. The protective cylinder 58 is sleeved on the linkage rod 53 and the telescopic rod 54, and the bottom end of the protective cylinder 58 is close to the top of the mounting box 45.

[0052] In this embodiment, the protective sleeve 58 covers the linkage rod 53 and the telescopic rod 54, protecting this vertical transmission component from the influence of the external environment and preventing human contact, thus ensuring operational safety.

[0053] In summary, compared with related technologies, this device, through the dual stimulation of mechanical shaking and wind simulation, can comprehensively and multidimensionally train the toughness of seedling stems and the gripping force of roots, while also achieving significant anti-lodging training effects without the need for human intervention.
