Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an unmanned continuous seedling feeding and supply mechanism for a rice transplanter. Background Technology

[0002] In the modernization of the rice planting industry, rice transplanters, with their high efficiency, have become key equipment for improving planting efficiency. According to statistics from the agricultural sector, compared to traditional manual transplanting, mechanized rice transplanting can increase efficiency by more than 20 times, effectively alleviating labor shortages during busy farming seasons. With the deep integration of cutting-edge technologies such as intelligent control and satellite navigation, rice transplanters have achieved unmanned automatic operation and automatic path planning in paddy fields, demonstrating excellent performance in precise positioning and automatic obstacle avoidance, providing strong support for the development of smart agriculture.

[0003] However, in the operation of rice transplanters, the seedling supply process has become a key bottleneck hindering the full realization of unmanned operation. Currently, most rice transplanters still rely on manual operation for seedling supply, requiring workers to frequently remove seedlings from the storage rack and place them one by one on the seedling tray. This manual seedling supply method is not only labor-intensive and inefficient, but also difficult to meet the needs of continuous operation of rice transplanters in large-scale planting scenarios. In addition, some seedling picking and supply mechanisms in existing technologies have drawbacks such as complex structure, poor reliability, and low seedling picking efficiency. The complex mechanical structure not only increases equipment costs and maintenance difficulty, but is also prone to failure, leading to inaccurate seedling picking and discontinuous seedling supply, causing frequent interruptions in transplanting operations, seriously affecting the overall operation progress and quality, and restricting the further development of the rice planting industry.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The unmanned continuous seedling feeding mechanism of this rice transplanter, through the setting of a seedling conveying unit, places the seedlings inside the seedling storage trough.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0024] Please see Figures 1-4This utility model provides a technical solution: an unmanned continuous seedling feeding and supply mechanism for a rice transplanter, including a placement frame 1 and a fixing plate 2. The fixing plate 2 is disposed on the inner side of the placement frame 1, and a seedling supply device is disposed on the outer surface of the placement frame 1. The seedling supply device includes a seedling conveying unit and a seedling transplanting unit. The seedling conveying unit is installed on the inner side of the placement frame 1, and the seedling transplanting unit is installed below the placement frame 1.

[0025] The seedling conveying unit includes a flip plate 3, which is movably connected to the inner side of a fixed plate 2. A seedling storage trough 4 is provided above the flip plate 3. A fixed block 5 is provided on the side of the placement rack 1. A flip seat 6 is movably connected to the outer surface of the fixed block 5. An electric push rod 7 is fixedly connected to the top of the flip seat 6. A connecting block 8 is provided on the top of the electric push rod 7. A motor assembly 9 is provided on the side of the placement rack 1. A threaded rod 10 is drivenly connected to the output shaft of the motor assembly 9. A moving block 11 is movably connected to the outer surface of the threaded rod 10. A bracket 12 is provided on the top of the moving block 11. An electromagnetic slide rail 13 is provided on the front of the placement rack 1. The outer surface of the electromagnetic slide rail 13 is movably connected to the lifting block 14, so that by setting up the seedling conveying unit, the seedlings are placed inside the seedling storage trough 4. When the motor assembly 9 drives the threaded rod 10 to rotate, and then the moving block 11 drives the support 12 to move, when the moving block 11 is aligned with the flipping plate 3, the corresponding electric push rod 7 is activated, so that the electric push rod 7 pushes the connecting block 8, and then the flipping plate 3 rotates around the central connecting axis of the fixed plate 2, thereby tilting the seedlings into the inside of the transport pipe, and then transferring them to the seedling transplanting unit through the transport pipe for subsequent work.

[0026] The threaded rod 10 passes through the two lifting blocks 14, so that the moving block 11 can be height adjusted when the lifting block 14 moves on the outer surface of the electromagnetic slide rail 13.

[0027] The seedling transplanting unit includes a placement seat 15, which is located below the placement frame 1. A seedling transfer component 16 is provided on the front of the placement seat 15. A rotating disc 18 is movably connected to the lower part of the seedling transfer component 16. A seedling transplanter 17 is connected to the outer surface of the rotating disc 18. A compaction wheel 19 is provided on the back of the seedling transplanter 17. By setting up the seedling transplanting unit, the seedlings inside the seedling storage trough 4 are transported to the inside of the seedling transfer component 16 through the transport pipe. The seedlings are then stored by the seedling transfer component 16 and rotated, so that the seedling transfer component 16 further transports the seedlings to the inside of the seedling transplanter 17. When the device moves, the rotating disc 18 drives the seedling transplanter 17 to rotate, thereby inserting the seedlings. The compaction wheel 19 further performs subsequent auxiliary compaction work on the seedlings.

[0028] The support 12 is equipped with a transport pipe inside, and the other end of the transport pipe is located above the seedling transfer component 16. The transport pipe is a retractable flexible hose, so that when the support 12 moves, the seedlings inside the seedling storage trough 4 can be further transferred to the seedling transfer component 16 through the transport pipe.

[0029] The flip plate 3 and the fixed plate 2 are connected by a bearing, which is a deep groove ball bearing, to ensure that the flip plate 3 rotates smoothly and smoothly, and to reduce friction loss.

[0030] The seedling transfer assembly 16 includes multiple circularly distributed seedling storage troughs. Each seedling storage trough has an anti-slip rubber pad on its inner wall to prevent the seedlings from slipping during transfer. The bottom of the seedling storage trough is equipped with an openable baffle for precise control of seedling placement.

[0031] The placement rack 1 is made of high-strength aluminum alloy and its surface is anodized to enhance corrosion resistance and wear resistance. The structural design of the placement rack 1 conforms to the principles of mechanics, reducing the overall weight while ensuring strength, making it easy to install and move.

[0032] The placement rack 1 is located on top of the placement base 15 and is fixedly connected to the placement base 15.

[0033] Working principle: The whole system consists of a placement frame 1, a fixing plate 2, and a seedling supply device, which includes a seedling conveying unit and a seedling transplanting unit. During seedling conveying, the seedlings are placed in the seedling storage trough 4 of the flipping plate 3. The motor assembly 9 drives the threaded rod 10 to rotate, which in turn moves the moving block 11 and the support 12. When the moving block 11 is aligned with the flipping plate 3, the electric push rod 7 pushes the connecting block 8, causing the flipping plate 3 (movably connected to the fixing plate 2 through a deep groove ball bearing) to rotate around the central axis. The seedlings are then poured into the retractable flexible hose transport tube in the support 12 and transferred to the seedling transplanting unit. At the same time, the threaded rod 10 passes through two lifting blocks 14. The lifting blocks 14 move on the electromagnetic slide rail 13 to adjust the height of the moving block 11, achieving precise docking. During the transplanting process, the transport pipe delivers the seedlings to the annular seedling storage trough (with anti-slip rubber pads on the inner wall and an openable baffle at the bottom) of the seedling transfer component 16 on the front of the placement seat 15. The rotation of the storage trough feeds the seedlings into the transplanter 17. When the device moves, the rotating disc 18 drives the transplanter 17 to rotate and transplant the seedlings. The compaction wheel 19 on the back of the transplanter 17 assists in compacting the seedlings. In addition, the placement frame 1 is made of high-strength aluminum alloy and has undergone anodizing treatment. Its mechanical structure design balances strength and lightness, ensuring stable operation of the mechanism.

[0034] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
