[0008] As a further solution of the present invention: a water tank is provided at the bottom end of the seedling replenishing platform, and three groups of water pipes are connected to the water tank close to the rice planting platform. The water pipes run through the upper end of the rice planting platform and are connected to a spraying piece at the other end. Five groups of nozzles are provided on both sides of the spraying piece.

[0009] As a further solution of the present invention: the top surface of the rice planting platform is provided with partitions at both ends of the spraying member, the partitions are provided with five groups of mounting holes at equal intervals, and the spray heads penetrate through the mounting holes.

[0010] As a further solution of the present invention: a mounting frame is fixedly arranged under the rice planting platform, L-shaped frames are arranged at both ends of the mounting frame, and the other end of the L-shaped frame is fixedly connected to the front end of the supporting base plate.

[0011] As a further solution of the present invention: a water inlet and a transparent window are provided on the right side of the water storage tank, and the transparent window is provided at the lower end of the water inlet.

[0012] As a further solution of the present invention: a rice planting assembly is installed at the front side of the lower end of the rice planting platform, and the rice planting assembly is provided with four groups.

[0013] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The present invention provides a reliable foundation for the seedling-replenishing assembly through the stable structure formed by the supporting side plates and the supporting bottom plate on both sides of the seedling-replenishing platform. The hydraulic pump in the seedling-replenishing assembly drives the telescopic parts, which can accurately control the lifting and lowering of the supporting connecting plate and the fixing frame, and then adjust the height of the seedling-replenishing plate. The seedling-replenishing plate is inclined at 45 degrees, and the seedlings are conveniently taken down by gravity. The movable limit plate on one side of the seedling-replenishing plate plays an important role. When the seedling-replenishing plate is lower than the seedling-replenishing platform, it effectively prevents the seedlings from sliding off and ensures the safety of seedling placement; when it is higher than the seedling-replenishing platform, it automatically changes the angle to make the seedlings slide smoothly to the seedling-replenishing platform, realizing the seamless connection of the seedlings from the storage to the seedling-replenishing position, reducing the manual handling and adjustment links, greatly improving the efficiency and accuracy of seedling-replenishing, making the transplanting operation process smoother and more efficient, and reducing the impact of untimely or inaccurate seedling-replenishing on the transplanting progress and quality;

[0015] 2. The auxiliary components on the rear end mounting plate of the seedling-replenishing platform play an important role in the present invention. The electric telescopic rod drives the push plate to push the seedlings on the seedling-replenishing platform to the seedling-planting platform, and assists the transplanting personnel to quickly place the seedlings on the transplanting components, thereby reducing the difficulty and labor intensity of manual operation. At the same time, the baffle at the center of the top surface of the seedling-replenishing platform can prevent the seedlings from accidentally sliding to other areas during the placement process, thus playing a good protective role. These designs not only improve the convenience of the seedling-replenishing operation, but also ensure the orderly handling of the seedlings during the entire transplanting process, avoid interruptions or errors in the operation caused by the scattering of seedlings, etc., ensure that the transplanter can work continuously and stably, and provide strong support for large-scale and efficient agricultural transplanting operations;

[0016] 3. The present invention transports water from the water tank to the spraying parts at the upper end of the rice planting platform through three groups of water pipes. The five groups of nozzles on both sides are evenly distributed through the mounting holes on the partition, so as to carry out comprehensive and precise irrigation of the rice planting area. This design ensures that the newly planted seedlings can obtain sufficient water in time, which is beneficial to improving the survival rate of the seedlings. The mounting frame under the rice planting platform is connected with the L-shaped frame and the supporting bottom plate of the rice planting platform to construct a stable overall structure. When the rice transplanter is operating in the field, it can effectively resist bumps and vibrations, ensure the stable operation of components such as rice planting, transplanting and irrigation, reduce the operation deviation caused by mechanical shaking, and improve the reliability and stability of the overall performance of the rice transplanter.

[0017] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0030] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see attached Figure 1 -Attached Fig.10 The present invention discloses a rice seedling delivery mechanism for a rice transplanter, comprising a rice planting platform 1, a rice planting platform 2 being fixedly connected to the rear end thereof, a supporting side plate 201 being fixedly arranged on both sides of the rice planting platform 2, providing a strong lateral support and positioning foundation for the entire rice planting structure, a supporting bottom plate 202 being fixedly arranged on the lower end of the supporting side plate 201 away from the rice planting platform 1, a rice planting component 3 being arranged on the top surface of the supporting bottom plate 202, the rice planting component 3 comprising a hydraulic pump 31, a telescopic member 32, a supporting connecting plate 33, a fixing frame 34 and a rice seedling placing plate 35, the hydraulic pump 31 being arranged on the supporting bottom plate 202, a supporting connecting plate 33, a fixing frame 34 and a rice seedling placing plate 35, the hydraulic pump 31 being arranged on the supporting bottom plate 202, and a supporting bottom plate 202 being arranged on the upper side of the supporting side plate 201. The front and rear sides of the top of the bottom plate 202 are supported, and the top is connected to the telescopic member 32. When the hydraulic pump 31 starts working, it can provide power support for the telescopic member 32. The two ends of the bottom surface of the supporting connecting plate 33 are connected to the telescopic member 32, and the side surfaces are fixedly connected to the front and rear sides of the outside of the fixed frame 34. When the telescopic member 32 is extended and retracted under the drive of the hydraulic pump 31, it can drive the supporting connecting plate 33 to achieve a position change in the vertical direction, and then drive the fixed frame 34 connected thereto to move synchronously. The seedling placement plate 35 is arranged on the inner side of the fixed frame 34.

[0032] In the first embodiment, the seedling placement plate 35 is tilted, and the tilt angle is 45°. There are five groups of seedling placement plates 35, and a movable limit plate 3501 is installed on the side close to the support side plate 201. The movable limit plate 3501 is installed on the side of the seedling placement plate 35 through a rotating shaft, and one side is in contact with the side of the support side plate 201 close to the fixed frame 34. A mounting plate is provided at the rear end of the seedling replenishing platform 2, and a baffle is provided at the center of the top surface. Auxiliary components 4 are provided at both ends of the mounting plate. The auxiliary component 4 includes a push plate 41, an electric telescopic rod 42 and a support frame 43. One end of the electric telescopic rod 42 passes through the mounting plate, and the other end face is connected to the center of one side of the push plate 41. The support frame 43 is arranged on the rear side of the mounting plate, and the inner center is fixedly connected to one end face of the electric telescopic rod 42.

[0033] Specifically, the seedling placement plate 35 is set at an inclined angle of 45°, so that the seedlings can slide down naturally on the placement plate in a relatively stable and smooth manner. The movable limit plate 3501 is connected to one side of the seedling placement plate 35 by a rotating shaft. The design of the rotating shaft gives the movable limit plate 3501 the ability to rotate flexibly. In the initial state, one side of the movable limit plate 3501 is tightly in contact with the side of the supporting side plate 201 close to the fixed frame 34, effectively preventing the seedlings from sliding out of the range of the seedling placement plate 35 due to vibration, shaking or other unexpected factors during the operation of the machine. The mounting plate provides a stable and reliable basic platform for the installation of the auxiliary component 4. When the electric telescopic rod 42 in the auxiliary component 4 receives the driving signal from the control system, it will perform a telescopic action according to the instruction. This telescopic movement can directly drive the push plate 41 connected thereto to move back and forth in the horizontal direction, and then push the seedlings on the seedling replenishing platform 2 to the position of the seedling planting platform 1.

[0034] In the second embodiment, a water storage tank 5 is provided at the bottom of the seedling replenishing platform 2, and three groups of water pipes 6 are connected to the water storage tank 5 near the side of the seedling planting platform 1. The water pipe 6 runs through the upper end of the seedling planting platform 1, and the other end is connected to a spraying member 7. Five groups of nozzles 8 are provided on both sides of the spraying member 7. The top surface of the seedling planting platform 1 is provided with a partition plate 9 at both ends of the spraying member 7. The partition plate 9 is equidistantly provided with five groups of mounting holes, and the nozzles 8 run through the mounting holes;

[0035] Specifically, the water tank 5 has sufficient water storage capacity to meet the large amount of water demand for seedling irrigation during the rice transplanting operation. It is located adjacent to one side of the rice planting platform 1 and is connected to three groups of water pipes 6, which run through the upper end of the rice planting platform 1 to smoothly transport the water in the water tank 5 to a specific position. At the other end of the water pipe 6, a spraying member 7 is connected, and five groups of nozzles 8 are symmetrically arranged on both sides. A partition 9 is installed on the top surface of the rice planting platform 1 at both ends of the spraying member 7. The partition 9 not only plays a certain protective and isolating role, but also has five groups of mounting holes equidistantly opened thereon. The nozzle 8 runs through the mounting hole, so that the nozzle 8 can be firmly fixed at a specific position above the rice planting platform 1, and with the help of the guiding and positioning function of the mounting hole, the nozzle 8 is guaranteed to have a stable direction and a precise angle during the water spraying process, so that water is evenly sprayed on the rice planting area, providing a suitable moisture environment for the rice seedlings, and greatly improving the quality of the rice transplanting operation.

[0036] Embodiment 3: A mounting frame is fixedly arranged below the rice planting platform 1, and L-shaped frames are arranged at both ends of the mounting frame, and the other end of the L-shaped frame is fixedly connected to the front end of the supporting bottom plate 202. A water inlet and a transparent window are arranged on the right side of the water storage tank 5, and the transparent window is arranged at the lower end of the water inlet. A rice planting assembly 10 is installed at the front side of the lower end of the rice planting platform 1, and the rice planting assembly 10 is provided with four groups;

[0037] Specifically, the mounting frame below the rice planting platform 1 and the L-shaped frames at both ends connect it to the supporting base plate 202 to enhance the structural stability and ensure that all components can work together normally when the rice transplanter is operating in bumpy farmland. There is a water inlet on the right side of the water tank 5 for convenient water adding, and the transparent window allows intuitive viewing of the water level and water quality. The four groups of rice planting components 10 on the front side of the lower end of the rice planting platform 1 can accurately plant rice according to preset parameters, and automatically adjust according to the actual soil conditions to ensure uniform planting density, seedling survival rate and growth quality, thereby improving work efficiency and quality.

[0038] Working principle:

[0039] First, the water in the water tank 5 is sent to the spraying part 7 of the planting platform 1 through three groups of water pipes 6, and is evenly sprayed through the nozzle 8. The nozzle 8 is accurately positioned with the help of the mounting hole of the partition 9 to replenish water for the seedlings and improve the survival rate. The mounting frame under the planting platform 1 is connected to the L-shaped frame to form a stable structure to reduce the interference of bumps on the operation. The transplanting component 10 is the core. The seedlings are grabbed and inserted into the soil according to the program. Parameters such as depth, strength and spacing can be automatically adjusted according to the soil conditions to ensure that the seedlings are firmly rooted and the planting density is uniform. When the seedlings need to be supplemented, the supporting side plates 201 of the supplementing platform 2 and the supplementing component 3 carried by the bottom plate are started, and the hydraulic pump 31 drives the telescopic member 32 to make the support The supporting connecting plate 33 drives the fixing frame 34 to rise and fall, so that the seedling placing plate 35 is at a suitable height, which is inclined at 45°. Five groups are designed to increase the amount of seedlings, and gravity is used to help the seedlings slide down. The movable limiting plate 3501 is installed on the side of the plate via a rotating shaft. When it is lower than the seedling replenishing platform 2, it prevents the seedlings from sliding. When it is higher than the seedling replenishing platform 2, the angle is changed to guide the seedlings to the seedling replenishing platform 2 to achieve automatic transfer. Then, the auxiliary component 4 of the mounting plate at the rear end of the seedling replenishing platform 2 operates, and the electric telescopic rod 42 penetrates the mounting plate to connect the push plate 41, and is fixed by the support frame 43 at the back. After receiving the command, the telescopic rod retracts and extends the push plate 41 to push the seedlings of the seedling replenishing platform 2 to the transplanting component 10. At this point, the entire work process ends.
