Technical Field

[0001] This utility model relates to the field of sweet potato planting technology, and in particular to a transplanting mechanism. Background Technology

[0002] In the process of sweet potato planting, it is often necessary to transplant sweet potato seedlings. In order to improve the transplanting efficiency, transplanting machines are often used instead of manual transplanting to achieve efficient transplanting of sweet potato seedlings.

[0003] To facilitate the sorting and transplanting of sweet potato seedlings of different sizes, sorting structures are often incorporated into the transplanting mechanism to separate the seedlings and ensure their proper growth after transplanting. For example, Chinese Patent CN220556868 U discloses a seedling sorting and transplanting machine that can sort sweet potato seedlings of different sizes, improving work efficiency and controlling planting density, which is beneficial for seedling growth. However, when sorting sweet potato seed tubers, these machines often cause them to get stuck between adjacent partitions or between a partition and the first baffle. Furthermore, the rotating blades can easily scratch the surface of the seed tubers, damaging them and affecting their post-transplant growth, which is detrimental to sweet potato cultivation. Utility Model Content

[0004] This utility model proposes a transplanting mechanism to solve the problem that existing sweet potato seed tubers are easily stuck between two adjacent partition plates or in the area between a partition plate and a first baffle plate, and the surface of the sweet potato seed tubers is easily scratched by the rotation of the pry bar, resulting in damage to the sweet potato seed tubers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transplanting mechanism, including a movable frame, wherein a screening mechanism is mounted on the top of the movable frame;

[0006] The screening mechanism includes a screening box with an internal cavity, a seedling feeding hopper connected to the cavity is installed on the top of the screening box, and three collection hoppers are installed at the bottom of the screening box. Each of the three collection hoppers has a seeding tube at its bottom end, and the bottom ends of the three seeding tubes all pass through a movable frame.

[0007] Two partition plates are installed inside the cavity, dividing the cavity into a first screening chamber, a second screening chamber, and a third screening chamber that are sequentially distributed along the sweet potato seed transport direction. Three first screening rollers are equally spaced in the first screening chamber, three second screening rollers are equally spaced in the second screening chamber, and three third screening rollers are equally spaced in the third screening chamber. The diameters of the first, second, and third screening rollers decrease in that order. A drive unit is also provided on one side of the screening box to drive the first, second, and third screening rollers to rotate synchronously.

[0008] Preferably, the first screen roller, the second screen roller, the third screen roller and the partition plate are all provided with a channel for transporting sweet potato seed tubers between them and the top of the screening box.

[0009] Preferably, the driving component includes a synchronous pulley installed at one end of each of the first, second, and third screen rollers, and a synchronous toothed belt is connected between each pair of adjacent synchronous pulleys. A motor is fixed on one side of the screening box, and the main shaft of the motor is connected to the third screen roller located on the far right.

[0010] Preferably, the bottom of the mobile frame is also connected to three furrow openers that are evenly spaced along its width, and the three furrow openers are respectively located in front of the three seeding tubes.

[0011] Preferably, the movable frame is also equipped with three electric push rods, and the telescopic ends of the three electric push rods all pass through the movable frame and are fixedly connected to the three trenchers respectively.

[0012] Preferably, a traction frame is also fixed to the front side of the mobile frame, and the traction frame is provided with a connection hole.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] (1) By setting up first, second and third screen rollers with different diameters in the screening box, sweet potato seed tubers of different sizes will fall through the gap between two adjacent first, second or third screen rollers when they are conveyed through the first, second and third screen rollers, thereby achieving the screening of sweet potato seed tubers. This facilitates the separate transplanting of sweet potato seed tubers of different sizes, avoids the problem of sweet potato seed tubers being stuck during screening, and also prevents damage to the surface of sweet potato seed tubers. This is conducive to the normal growth of sweet potato seed tubers after transplanting and achieves efficient planting of sweet potatoes.

[0015] (2) By setting electric push rods, not only can the three furrow openers be driven to rise and fall synchronously and adjust the height of the furrow openers to adjust the furrowing depth, but also each electric push rod can be controlled individually by the controller according to the size of the sweet potato seed tuber, so that the furrowing depth of the three furrow openers is different, in order to meet the transplanting needs of sweet potato seed tubers of different sizes, which can further facilitate the transplanting of sweet potato seed tubers, thereby improving the practicality of the transplanting mechanism and facilitating the efficient transplanting of sweet potato seed tubers.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5As shown, a transplanting mechanism includes a mobile frame 1, with a screening mechanism mounted on the top of the mobile frame 1; the mobile frame 1 is also equipped with a rechargeable power supply battery and a controller for operating the transplanting mechanism; the screening mechanism includes a screening box 3 with an internal cavity, a seedling hopper 2 connected to the cavity is mounted on the top of the screening box 3, and three collection hoppers 10 are mounted on the bottom of the screening box 3, each of the three collection hoppers 10 has a sowing tube 6 at its bottom end, and the bottom ends of the three sowing tubes 6 all penetrate the mobile frame 1;

[0025] Two partition plates are installed inside the cavity, dividing the cavity into a first screening chamber, a second screening chamber, and a third screening chamber that are sequentially distributed along the sweet potato seed transport direction. Three first screening rollers 7 are equally spaced in the first screening chamber, three second screening rollers 8 are equally spaced in the second screening chamber, and three third screening rollers 9 are equally spaced in the third screening chamber. The diameters of the first screening rollers 7, the second screening rollers 8, and the third screening rollers 9 decrease in that order. A drive unit is also provided on one side of the screening box 3 to drive the first screening rollers 7, the second screening rollers 8, and the third screening rollers 9 to rotate synchronously.

[0026] Furthermore, in order to ensure the transport of sweet potato seed tubers, the first screening roller 7, the second screening roller 8, the third screening roller 9, and the partition plate all have channels for transporting sweet potato seed tubers between them and the top of the inner part of the screening box 3.

[0027] Specifically, regarding the aforementioned driving components, such as Figure 4 and Figure 5 As shown, the driving component includes a synchronous pulley 13 installed at one end of each of the first screen roller 7, the second screen roller 8 and the third screen roller 9. A synchronous toothed belt 11 is connected between each two adjacent synchronous pulleys 13. A motor 12 is fixed on one side of the screening box 3, and the main shaft of the motor 12 is connected to the third screen roller 9 located on the far right.

[0028] As described above, during sweet potato seed transplanting, the sweet potato seed tubers can be loaded into the seedling hopper 2. The motor 12 is then started via the controller, and the three first screening rollers 7, second screening rollers 8, and third screening rollers 9 rotate synchronously under the transmission of the synchronous toothed belt 11 and synchronous pulley 13. When some sweet potato seed tubers fall into the first screening chamber, the rotation of the three first screening rollers 7 transports them from the first screening chamber to the second screening chamber. Subsequently, the rotation of the three second screening rollers 8 transports them into the third screening chamber. During this transport process, the slender sweet potato seed tubers are separated by adjacent rollers... The sweet potato seed tubers fall into the corresponding collection hopper 10 through the gap between the first screening rollers 7. The thicker sweet potato seed tubers fall into the corresponding collection hopper 10 through the gap between two adjacent second screening rollers 8. The large sweet potato seed tubers fall into the corresponding collection hopper 10 through the gap between two adjacent third screening rollers 9 under the rotation of the three third screening rollers 9. Then, the slender sweet potato seed tubers, the thicker sweet potato seed tubers, and the large sweet potato seed tubers are planted separately through the planting tube 6 at the bottom of the collection hopper 10. This facilitates the transplanting of sweet potato seed tubers of different sizes, which is beneficial to the growth of sweet potato seed tubers after transplanting.

[0029] Meanwhile, in this embodiment, such as Figure 1 and Figure 3 As shown, the bottom of the mobile frame 1 is also connected to three furrow openers 4 that are evenly distributed along its width direction, and the three furrow openers 4 are respectively located in front of the three seeding tubes 6.

[0030] When the mobile frame 1 moves, it can drive the three furrow openers 4 to move synchronously to dig planting furrows on the planting ground corresponding to the three sowing tubes 6. Then, the three sowing tubes 6 will sow the selected sweet potato seed tubes into their corresponding planting furrows to complete the transplanting. In this way, the transplanting mechanism integrates furrow opening and transplanting, which greatly improves the transplanting efficiency of sweet potato seed tubers and facilitates the rapid transplanting of sweet potato seed tubers.

[0031] Furthermore, in this embodiment, as Figure 1 and Figure 3 As shown, the movable frame 1 is also equipped with three electric push rods 5, and the telescopic ends of the three electric push rods 5 all pass through the movable frame 1 and are fixedly connected to the three trenchers 4 respectively.

[0032] When the mobile frame 1 moves the trencher 4 to trench, the controller can activate the three electric push rods 5, so that the three electric push rods 5 drive the three trenchers 4 to rise and fall synchronously, thereby adjusting the height of the trencher 4 and thus adjusting the trenching depth.

[0033] Furthermore, each electric push rod 5 can be individually controlled by the controller according to the size of the sweet potato seed tuber, so that the trenching depth of the three trenchers 4 can be adapted to the size of the sweet potato seed tuber, further facilitating the transplanting of sweet potato seed tubers, thereby improving the practicality of the transplanting mechanism and promoting the efficient transplanting of sweet potato seed tubers.

[0034] Additionally, in this embodiment, as Figure 1 As shown, a traction frame is also fixed to the front side of the mobile frame 1, and the traction frame is provided with a connection hole.

[0035] When transplanting sweet potato seed tubers, the mobile frame 1 can be connected to external agricultural machinery through the traction frame and connecting holes, so that the mobile frame 1 can be moved along the sweet potato planting ground by the external agricultural machinery, thereby facilitating the transplanting of sweet potatoes.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
