Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery transplanting technology, and in particular to an automatic vegetable seedling transplanting machine. Background Technology

[0002] In the process of vegetable cultivation, seedling transplanting is one of the key steps, which directly affects the subsequent growth and yield of vegetables.

[0003] However, in existing technologies, traditional vegetable seedling transplanting relies heavily on manual operation. Workers need to manually remove the seedlings from the seedling trays and plant them one by one in the field. This is not only labor-intensive and time-consuming, but also makes it difficult to ensure the consistency of plant spacing and row spacing, resulting in uneven seedling growth space and affecting the overall growth quality. In addition, some simple transplanting equipment has the problems of single function and low positioning accuracy. Most equipment can only achieve simple seedling transportation, cannot accurately control the transplanting position, and lacks flexible position adjustment structure, making it difficult to adapt to the transplanting needs of different types of vegetables. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high labor intensity, low efficiency, poor positioning accuracy, and difficulty in adapting to diverse transplanting needs in the existing technology of vegetable seedling transplanting, and to propose an automatic vegetable seedling transplanting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic vegetable seedling transplanter, comprising a pushing mechanism and a positioning mechanism. The pushing mechanism includes a gearbox, a fixed plate, and a movable plate. The fixed plate is fixedly installed on the top of the gearbox. A driven gear is fixedly installed at the center of the bottom of the movable plate. A transmission rod is rotatably installed inside the gearbox. A bevel gear is fixedly installed on the outer wall of the transmission rod. One side of the bevel gear is attached to the inner wall of the gearbox. The driven gear meshes with the bevel gear. Multiple positioning cylinders are fixedly installed in a ring at equal intervals inside the movable plate. A feeding pipe is fixedly installed at the edge of the fixed plate. One of the positioning cylinders is connected to the feeding pipe. One end of the transmission rod is connected to an external power source.

[0006] Preferably, a base rod is fixedly connected to the bottom of the bearing seats at both ends of the transmission rod, and a slider is slidably connected to the upper surface of the base rod.

[0007] Preferably, the top of the slider is fixedly connected to the bottom of the gearbox, and both sides of the slider are threaded with limit screws.

[0008] Preferably, the positioning mechanism includes a positioning frame, a first electric cylinder is fixedly mounted on one side of the positioning frame, and a transmission plate is fixedly mounted on one end of the piston rod of the first electric cylinder.

[0009] Preferably, a guide rod is fixedly installed on the top of the positioning frame, and the transmission plate is slidably connected to the guide rod.

[0010] Preferably, a pressure rod is rotatably connected to the bottom of the transmission plate, a limit plate is fixedly installed on one side of the positioning frame, and the pressure rod is located at the top of the positioning cylinder.

[0011] Preferably, a second electric cylinder is rotatably mounted on the lower surface of the transmission plate, and one end of the piston rod of the second electric cylinder is rotatably connected to the top of the pressure rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, through the coordinated operation of the pushing mechanism and the positioning mechanism, the transmission structure consisting of the transmission rod, bevel gear, and driven gear drives the movable plate and positioning cylinder to rotate automatically. Combined with the feeding pipe, the seedlings are automatically received and transported. At the same time, the positioning mechanism pushes out the seedlings to complete the transplanting. The entire process replaces manual operation, greatly reduces labor intensity, significantly improves transplanting efficiency, effectively ensures the accuracy of the transplanting position, reduces seedling damage, and improves the transplanting survival rate.

[0014] 2. In this utility model, the overall position of the pushing mechanism can be flexibly adjusted through the sliding cooperation between the bottom rod and the slider. With the fixing effect of the limiting screw, it can stably adapt to the diverse transplanting requirements of different vegetable varieties for plant spacing and row spacing. At the same time, the positioning cylinders distributed at equal intervals in the ring on the movable plate are precisely connected to the feeding pipe on the fixed plate. The limitation of the sliding range of the transmission plate by the limiting plate in the positioning mechanism further ensures the stability and consistency of the transplanting process. It is suitable for large-scale vegetable planting scenarios and fills the gap of poor adaptability and insufficient stability of existing transplanting equipment. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an automatic vegetable seedling transplanter, including a pushing mechanism 1 and a positioning mechanism 2. The pushing mechanism 1 includes a gearbox 12, a fixed plate 13, and a movable plate 14. The fixed plate 13 is fixedly installed on the top of the gearbox 12. A driven gear 110 is fixedly installed at the center of the bottom of the movable plate 14. A transmission rod 18 is rotatably installed inside the gearbox 12. A bevel gear 19 is fixedly installed on the outer wall of the transmission rod 18. One side of the bevel gear 19 is attached to the inner wall of the gearbox 12. The driven gear 110... The gear 10 meshes with the bevel gear 19. Multiple positioning cylinders 15 are fixedly installed in a ring at equal intervals inside the movable plate 14. A feed pipe 111 is fixedly installed at the edge of the fixed plate 13. One of the positioning cylinders 15 is connected to the feed pipe 111. One end of the transmission rod 18 is connected to an external power source. The bottom of the bearing seats at both ends of the transmission rod 18 is fixedly connected to a bottom rod 11. A slider 16 is slidably connected to the upper surface of the bottom rod 11. The top of the slider 16 is fixedly connected to the bottom of the gearbox 12. Limit screws 17 are threadedly connected to both sides of the slider 16.

[0023] The specific setup and function of this embodiment are described in detail below. The entire device is mounted on a mobile device. During use, the transmission rod 18 is driven to rotate by an external power source. Because the bevel gear 19 fixedly installed on the outer wall of the transmission rod 18 is in contact with the inner wall of the gearbox 12 and meshes with the driven gear 110 fixed at the bottom center of the movable plate 14, the transmission rod 18 drives the bevel gear 19 to rotate, which in turn drives the driven gear 110 to rotate the movable plate 14. Multiple positioning cylinders 15 fixed in a ring at equal intervals inside the movable plate 14 rotate synchronously with the movable plate 14. When one of the positioning cylinders 15 rotates to the position where it connects with the feeding pipe 111 fixed at the edge of the fixed plate 13, the vegetable seedlings enter the positioning cylinder 15 through the feeding pipe 111, completing the seedling receiving. At the same time, the bottom rod 11 fixed at the bottom of the bearing seats at both ends of the transmission rod 18 provides support for the overall mechanism. The slider 16 slidably connected to the upper surface of the bottom rod 11 can drive the gearbox 12 to slide along the bottom rod 11, adjusting the overall position of the pushing mechanism 1. The limiting screws 17 threaded on both sides of the slider 16 After the position adjustment is completed, tighten the screws to fix the slider 16 and the base rod 11 relative to each other, ensuring the stability of the mechanism. The positioning mechanism 2, in conjunction with the pushing mechanism 1, accurately positions the transplanting position, ensuring that the seedlings are accurately transplanted to the designated location. Through the transmission of the transmission rod 18, the bevel gear 19, and the driven gear 110, the movable plate 14 and the positioning cylinder 15 are driven to rotate automatically. Combined with the feeding pipe 111, the seedlings are automatically received and transported, replacing manual transplanting, greatly reducing the intensity of manual labor and improving transplanting efficiency. Secondly, the positioning cylinders 15, which are evenly distributed in a ring on the movable plate 14, are precisely matched with the feeding pipe 111, ensuring that each positioning cylinder 15 can stably receive the seedlings. At the same time, the positioning mechanism 2 ensures the accuracy of the transplanting position, reduces the seedling transplanting deviation, and improves the transplanting survival rate. Furthermore, the slider 16 on the base rod 11 can drive the pushing mechanism 1 to flexibly adjust its position to adapt to the transplanting needs of different row spacing and plant spacing. The limiting screws 17 on both sides of the slider 16 can effectively fix the adjusted position, preventing the mechanism from shifting during operation and ensuring transplanting consistency.

[0024] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 2 includes a positioning frame 21. A first electric cylinder 22 is fixedly installed on one side of the positioning frame 21. A transmission plate 23 is fixedly installed on one end of the piston rod of the first electric cylinder 22. A guide rod 25 is fixedly installed on the top of the positioning frame 21. The transmission plate 23 is slidably connected to the guide rod 25. A pressure rod 26 is rotatably connected to the bottom of the transmission plate 23. A limit plate 24 is fixedly installed on one side of the positioning frame 21. The pressure rod 26 is located on the top of the positioning cylinder 15. A second electric cylinder 27 is rotatably installed on the lower surface of the transmission plate 23. One end of the piston rod of the second electric cylinder 27 is rotatably connected to the top of the pressure rod 26.

[0025] The overall effect of this embodiment is that the positioning frame 21 provides support for the positioning mechanism 2. When the movable plate 14 in the pushing mechanism 1 drives the positioning cylinder 15 to rotate to the transplanting position, the first electric cylinder 22 fixed on one side of the positioning frame 21 is activated. Its piston rod pushes the transmission plate 23 to slide along the guide rod 25 fixed at the top of the positioning frame 21, adjusting the height of the transmission plate 23 so that the pressure rod 26 rotatably connected to the bottom of the transmission plate 23 is inserted into the positioning cylinder 15, thereby pushing the seedling out for cultivation. During the rotation of the pressure rod 26, the second electric cylinder 27 rotatably mounted on the lower surface of the transmission plate 23 is activated. Its piston rod extends and retracts, driving the pressure rod 26 to rotate around the connection point with the transmission plate 23, so that the pressure rod 26 rotates into the inner wall of the positioning cylinder 15 to avoid damaging the seedling and assist the seedling. After the seedling is removed from the positioning cylinder 15, the seedling is transplanted. At the same time, the limiting plate 24 fixed on one side of the positioning frame 21 can limit the sliding range of the transmission plate 23, preventing the transmission plate 23 from deviating from the preset position due to excessive sliding. This ensures that the pressure rod 26 can always act accurately on the positioning cylinder 15, and work with the pushing mechanism 1 to achieve precise seedling transplantation. The second electric cylinder 27 drives the pressure rod 26 to rotate, realizing flexible adjustment of the position and angle of the pressure rod 26. This can accurately adapt to the transplanting needs of different sizes of positioning cylinders 15 and seedlings, improving positioning flexibility. The limiting plate 24 limits the sliding range of the transmission plate 23, preventing the positioning deviation caused by component displacement. At the same time, the pressure rod 26 acts accurately on the seedling in the positioning cylinder 15, which, together with the pushing mechanism 1, further improves the seedling transplanting position accuracy, reduces transplanting errors, and ensures the consistency of seedling growth space.

[0026] The usage and working principle of this device are as follows: Before use, the slider 16, which is slidably connected to the upper surface of the base rod 11, drives the gearbox 12 to slide along the base rod 11, adjusting the overall position of the pushing mechanism 1. After the position is adjusted, tighten the limiting screws 17 threaded on both sides of the slider 16 to achieve relative fixation between the slider 16 and the base rod 11. Start the external power source, which drives the transmission rod 18 to rotate. The transmission rod 18 drives the bevel gear 19 to rotate, which in turn drives the driven gear 110 to rotate the movable plate 14. When one of the positioning cylinders 15 rotates to the position where it connects with the feeding pipe 111 fixed at the edge of the fixed plate 13, the vegetable seedlings enter the positioning cylinder 15 through the feeding pipe 111, completing the seedling reception. Subsequently, the positioning frame 21 in the positioning mechanism 2... The first electric cylinder 22, which is fixed on the side, is activated. Its piston rod pushes the transmission plate 23 to slide along the guide rod 25 fixed at the top of the positioning frame 21, adjusting the height of the transmission plate 23 so that the pressure rod 26, which is rotatably connected to the bottom of the transmission plate 23, is aligned with the positioning cylinder 15. Then, the second electric cylinder 27, which is rotatably mounted on the lower surface of the transmission plate 23, is activated. Its piston rod extends and retracts, causing the pressure rod 26 to rotate around the connection point with the transmission plate 23, so that the pressure rod 26 rotates into the inner wall of the positioning cylinder 15 and inserts into the interior of the positioning cylinder 15, pushing the seedling out of the positioning cylinder 15 for cultivation. After completing one seedling transplant, the movable plate 14 continues to drive the next positioning cylinder 15 to rotate to the position connected to the feed pipe 111, repeating the above seedling receiving, conveying and transplanting steps to realize continuous vegetable seedling transplanting operations.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
