Description

Technical Field

[0001] The utility model belongs to the technical field of rice seedling raising, in particular to a rice seedling raising device for planting. Background Art

[0002] In modern agricultural production, greenhouse rice seedling cultivation technology has become an important means of improving the quality and efficiency of rice seedling production. By raising seedlings in a controlled environment, greenhouse rice seedling cultivation effectively mitigates the impact of fluctuating natural conditions on the seedling production process, thereby improving the success rate and quality of seedling production. The placement and management of seedling trays is a critical step in greenhouse rice seedling cultivation. Typically, seedling trays need to be neatly arranged on the seedling bed (the greenhouse floor) for easy management and observation. This process is crucial to the success of seedling production and directly impacts subsequent transplanting and ultimate yield.

[0003] In traditional greenhouse rice seedling cultivation, seedling trays typically need to be manually moved and placed one by one on the seedling bed. This process is not only time-consuming and labor-intensive, but can also lead to misaligned placement of the trays due to improper handling, thus compromising seedling production. Furthermore, manual handling can lead to damage, impacting seedling success rates. Utility Model Content

The push plate abuts the outer wall of the rice seedling tray. When the multi-axis movable frame assembly drives the rice seedling tray carrying and placing box to the desired placement position of the rice seedling tray in the rice seedling greenhouse, the Z-axis terminal of the multi-axis movable frame assembly drives the rice seedling tray carrying and placing box to the ground. The electric telescopic rod drives the push plate to push the rice seedling tray out of the rice seedling tray carrying and placing box to the desired position on the ground. The inner wall of the push plate is also provided with a guide assembly for neatly placing the rice seedling trays. This not only replaces the manual method of placing rice seedlings one by one in the greenhouse, but also allows for neat batch placement.

[0006] Preferably, the guide assembly includes detachable anti-deflection guide plates symmetrically mounted on both ends of the inner wall of the pushing plate, and the two anti-deflection guide plates are symmetrically arranged on both sides of the rice seedling raising tray to guide the unloading of the rice seedling raising tray.

[0007] Preferably, a plurality of mounting holes are provided at equal distances on both ends of the inner wall of the pushing plate, and locking bolts are passed through the mounting holes from the back side of the pushing plate to be threadedly connected to the anti-deflection guide plate.

[0008] Preferably, the lower portion of the discharge port of the rice seedling raising tray carrying the placing box is integrally connected with a downward slope, and the downward slope provides a buffer for the rice seedling raising tray when it slides down to the greenhouse ground.

[0015] In this rice seedling raising device, the seedling tray carrying placement box can accurately place the seedling tray in the desired position through the descending action of the Z-axis guide rail. Driven by the electric telescopic rod, the push plate pushes the seedling tray out smoothly, and the anti-deflection guide plate ensures that the seedling tray does not deviate during the pushing process. The seedling tray can be accurately placed in the predetermined position, reducing the deviation that may occur during manual placement and improving the placement accuracy of the seedling tray. Compared with the traditional method of manually bending over to carry the seedling tray, this technical solution greatly improves the degree of automation, reduces the frequency of manual operation, reduces labor intensity, and also improves work efficiency.

[0016] After the seedling tray carrying and placing box pushes the seedling tray out through the pushing plate, the anti-deflection guide plate ensures that the seedling tray slides in a straight line for neat placement. The seedling tray can be neatly arranged on the seedling bed, which is convenient for subsequent management and observation, and promotes the healthy growth of rice seedlings.

[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0026] This embodiment provides Figures 1 to 4The rice seedling raising device shown in the figure includes a multi-axis movable frame assembly 1 erected in a rice seedling raising greenhouse. The terminal end of the Z-axis of the multi-axis movable frame assembly 1 is provided with a seedling tray carrying and placing box 7. The seedling tray carrying and placing box 7 is connected to the terminal end of the Z-axis through a rotating component. The seedling tray carrying and placing box 7 is a container for loading and transporting the seedling tray. It can rotate so as to change direction when unloading and loading the seedling tray, thereby simplifying the loading and unloading process of the seedling tray and improving work efficiency. One side of the seedling tray carrying and placing box 7 is provided with a discharge port, and a plurality of rice seedling trays 19 are placed flush with the inner bottom wall of the seedling tray carrying and placing box 7, each rice seedling tray 19 contains rice seedlings, and a row of rice seedling trays 19 are provided behind the inner wall of the seedling tray carrying and placing box 7, and a discharge assembly is provided. The discharge assembly includes an electric telescopic rod 21 installed on one of the longitudinal inner walls of the seedling tray carrying and placing box 7 and a push plate 20 installed on the telescopic free end of the electric telescopic rod 21. The push plate 20 pushes against the inner wall of the seedling tray 7. Connected to the outer wall of the rice seedling tray 19, when the multi-axis mobile frame assembly 1 drives the rice seedling tray carrying and placing box 7 to the desired placement position of the rice seedling tray 19 in the rice seedling greenhouse, the Z-axis terminal of the multi-axis mobile frame assembly 1 drives the rice seedling tray carrying and placing box 7 to descend close to the ground, and the electric telescopic rod 21 drives the push plate 20 to push the rice seedling tray 19 out of the rice seedling tray carrying and placing box 7 to the desired position on the ground. The inner wall of the push plate 20 is also provided with a guide component for the rice seedling tray 19 to be unloaded and neatly placed. This not only replaces the manual method of placing rice seedlings one by one in the greenhouse, but also allows for neat placement of rice seedlings in batches.

[0027] In this embodiment, the guide assembly includes detachable anti-deflection guide plates 22 symmetrically installed on both ends of the inner wall of the pushing plate 20. The two anti-deflection guide plates 22 are symmetrically arranged on both sides of the rice seedling raising tray 19 to guide the unloading of the rice seedling raising tray 19.

[0028] In this embodiment, the rice seedling tray 19 is the actual tray used for raising rice seedlings, containing the rice seedlings being grown. When the rice seedling tray 19 is ejected from the tray support and placement box 7, two anti-deflection guide plates 22 guide its downward movement, ensuring a smooth ejection of the rice seedling tray 19 from the tray support and placement box 7. As the rice seedling tray 19 slides down the lower slope 16, the anti-deflection guide plates 22 gradually lose their guiding effect until the rice seedling tray 19 completely slides out of the lower slope 16 and reaches the desired position.

[0029] In this embodiment, a plurality of mounting holes 23 are equidistantly provided at both ends of the inner wall of the pushing plate 20 , and locking bolts 24 are passed through the mounting holes 23 from the back side of the pushing plate 20 and are threadedly connected to the anti-deflection guide plate 22 .

[0030] In this embodiment, a downward slope 16 is integrally connected to the lower portion of the discharge port of the rice seedling tray carrying and placing box 7. The downward slope 16 cushions the transition of the rice seedling tray 19 from sliding down to the greenhouse floor. The downward slope 16 provides a buffering ramp when the rice seedling tray is pushed out of the rice seedling tray carrying and placing box 7, preventing the rice seedling tray from falling directly to the ground and being damaged.

[0031] In this embodiment, the multi-axis mobile frame assembly 1 includes four support columns 2 arranged in a rectangular distribution, Y-axis guide rails 3 symmetrically installed on the top of two of the support columns 2, an X-axis guide rail 5 slidably installed between the two Y-axis guide rails 3, and a Z-axis guide rail 6 slidably connected to the inner wall of the X-axis guide rail 5.

[0032] In this embodiment, a mounting box 13 is fixed to the bottom end of the Z-axis guide rail 6, and the rotating component includes a servo motor 14 mounted on the inner wall of the mounting box 13, and the output shaft of the servo motor 14 is fixedly connected to the shaft hole 15 on the top surface of the seedling tray supporting and placing box 7. After the interior of the rice seedling tray carrying and placing box 7 is transported well, the rice seedling tray 19 to be placed is transported from the transport place to the rice seedling tray carrying and placing box 7, which is convenient for transporting the rice seedling tray 19. After the interior of the rice seedling tray carrying and placing box 7 is transported well, the rice seedling tray carrying and placing box 7 is rotated 180 degrees again to return to its initial position, so that the unloading port of the rice seedling tray carrying and placing box 7 is back to the control box 11 and moves toward the depth of the greenhouse. The servo motor 14 provides power for driving the rotation of the seedling raising tray carrying placement box 7 to achieve automatic steering of the seedling raising tray.

[0033] In this embodiment, a control box 11 is installed on the inner wall of one of the supporting columns 2. The surface of the control box 11 has a display screen and control buttons. A fixed ear plate 17 is welded above the unloading port and on the top surface of the seedling tray supporting box 7. A camera 18 is installed on the inner wall of the fixed ear plate 17. The camera 18 is connected to the control box 11 via a WIFI network to transmit the monitoring image to the display screen.

[0034] In this embodiment, extension columns 8 are welded to the bottom surfaces of the two Y-axis guide rails 3 and on one side close to the adjacent support columns 2 , and auxiliary moving components 12 are provided on the bottom surfaces of the four extension columns 8 .

[0035] In this embodiment, the auxiliary movement assembly 12 includes a hydraulic lifting column 9 installed on the bottom surface of each extension column 8 and a travel wheel 10 provided at the lifting end of the bottom end of the hydraulic lifting column 9.

[0036] In this embodiment, the upper portion of the running wheel 10 is installed in the form of an inverted U-shaped card plate, and the bottom lifting end of the hydraulic lifting column 9 is fixedly connected to the U-shaped card plate. When the multi-axis mobile frame assembly 1 needs to be moved, the four hydraulic lifting columns 9 simultaneously drive the running wheel 10 to descend to the ground and prop up the multi-axis mobile frame assembly 1 so that the fixed base 4 is off the ground. The movement of the multi-axis mobile frame assembly 1 is completed by pushing the supporting columns 2. A fixed base 4 is welded to the bottom surface of each supporting column 2. When it is not necessary to move, the fixed base 4 is fixed to the ground in the greenhouse. The hydraulic lifting column 9 is used to control the lifting and lowering of the running wheel 10. When the equipment needs to be moved, the hydraulic lifting column 9 lowers the running wheel 10, and the equipment can be moved by the running wheel 10; when the equipment reaches the designated position, the hydraulic lifting column 9 retracts the running wheel 10, and the equipment is fixed in that position.

[0037] Working principle:

[0038] After the rice seedling raising device is started, the operator inputs the target position information through the control box 11. The camera 18 is turned on to monitor the position of the seedling tray carrying and placing box 7 in real time. The multi-axis movable frame assembly 1 is initialized and positioned by the X-axis guide rail 5, the Y-axis guide rail 3 and the Z-axis guide rail 6 to ensure that the seedling tray carrying and placing box 7 is in the initial position. The operator sets the target position according to the actual situation, and the camera 18 continuously monitors the movement process of the seedling tray carrying and placing box 7, and transmits the real-time image to the display screen of the control box 11. The operator continuously checks the monitoring screen. When the camera 18 monitors that the seedling tray carrying and placing box 7 has reached the predetermined position, the operator manually controls the button to stop the seedling tray carrying and placing box 7 from moving forward.

[0039] The operator starts the lowering operation of the Z-axis guide rail 6, causing the seedling tray support box 7 to descend along the Z-axis guide rail 6 to an appropriate height. The seedling tray support box 7 descends to a height close to the ground, ready for unloading the seedling tray 19. If the direction of the seedling tray support box 7 needs to be changed, the servo motor 14 will drive the seedling tray support box 7 to rotate 180 degrees through the shaft hole 15 to accommodate subsequent operations. The electric telescopic rod 21 drives the push plate 20 to push the seedling tray 19 out of the seedling tray support box 7. During the pushing process, the anti-deflection guide plate 22 ensures that the seedling tray 19 does not deviate, ensuring that it moves smoothly outward along the push plate 20.

[0040] After the seedling tray 19 is completely pushed out of the seedling tray carrying and placing box 7, it enters the lower sliding slope 16. On the sliding slope 16, the seedling tray 19 continues to slide. As the sliding distance increases, the anti-deflection guide plate 22 gradually loses its guiding effect on the seedling tray 19. Finally, the seedling tray 19 slides to the designated position, completing the unloading operation.

[0041] After unloading is completed, the seedling tray carrying and placing box 7 rises back to its original height. To change the direction of the seedling tray carrying and placing box 7, the servo motor 14 will drive the seedling tray carrying and placing box 7 to rotate 180 degrees through the shaft hole 15, so that the seedling tray carrying and placing box 7 returns to the direction of the initial unloading port facing the control electric box 11. If further loading is required, the above steps are repeated until all seedling trays 19 have been placed.
