[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0046] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] In one embodiment, Figures 1 to 4 As shown, the embodiment of the present application further provides an automatic rice seedling replenishment device 1, which may specifically include a rice seedling delivery mechanism 100 and a rice seedling storage mechanism 200, wherein the rice seedling delivery mechanism 100 may specifically include a rice seedling delivery channel 110 and a first rice seedling delivery power module 120 for driving the rice seedlings to be delivered along the rice seedling delivery channel 110. The rice seedling storage mechanism 200 may specifically include a rice seedling storage tray 210, a second rice seedling delivery power module 220 and a limiting guide 260, wherein the rice seedling storage tray 210 is tilted above the rice seedling delivery channel 110, and the second rice seedling delivery power module 220 is movably disposed on the rice seedling storage tray 210 to drive the rice seedlings on the rice seedling storage tray 210 to be delivered to the rice seedling delivery channel 110. The limiting guide 260 is connected to the bottom end of the seedling storage tray 210 to prevent the seedlings on the seedling storage tray 210 from falling when the second seedling feeding power module 220 is stationary, and to guide the transfer of the seedlings on the seedling storage tray 210 when the second seedling feeding power module 220 is running, so as to cooperate with the second seedling feeding power module 220 to transfer the seedlings on the seedling storage tray 210 to the seedling feeding channel 110.

[0048] It can be understood that the automatic seedling replenishing device 1 of the embodiment of the present application can be specifically applied to the automatic seedling replenishing operation of the rice transplanter, that is, when the planting part of the rice transplanter is insufficient (specifically, less than a preset number), the stored seedlings are automatically delivered to the planting part of the rice transplanter by the automatic seedling replenishing device 1. Therefore, the automatic seedling replenishing device 1 of the embodiment of the present application can be designed separately so that it can be directly mounted on a rice transplanter on the market for use, or it can be directly used as a mechanism of the rice transplanter and added to any existing type of rice transplanter to form a new rice transplanter for use. The bottom end of the rice seedling storage tray 210 mentioned above specifically refers to the end of the rice seedling storage tray 210 adjacent to the rice seedling delivery channel 110. Similarly, the top end of the rice seedling storage tray 210 mentioned below specifically refers to the end of the rice seedling storage tray 210 away from the rice seedling delivery channel 110. The aforementioned limiting guide 260 can prevent the seedlings on the seedling storage tray 210 from falling when the second seedling feeding power module 220 is stationary. Specifically, when the second seedling feeding power module 220 is not started, it can prevent the seedlings on the seedling storage tray 210 from falling by blocking the transmission direction of the second seedling feeding power module 220 through its own structure (such as an arc bend). That is, it prevents the seedlings on the seedling storage tray 210 from falling onto the seedling feeding channel 110 under the action of gravity due to the inclined setting of the seedling storage tray 210. Therefore, the limiting guide 260 can specifically be a limiting guide plate or other structure that can realize both the above-mentioned anti-falling limiting function and the above-mentioned transmission guiding function.

[0049] In addition, the seedling storage tray 210 is tilted above the seedling delivery channel 110 and can be specifically as follows: Figure 1As shown, the width direction of the seedling storage tray 210 is made perpendicular to the conveying direction of the seedling delivery channel 110, so that the rolling seedling delivery structure 220 can better deliver the seedlings to the seedling delivery channel 110 along the conveying direction of the seedling delivery channel 110. Alternatively, the width direction of the seedling storage tray 210 is made parallel to the conveying direction of the seedling delivery channel 110, so that the rolling seedling delivery structure 220 can deliver the seedlings to the seedling delivery channel 110 on either side of the width direction of the seedling delivery channel 110 along the direction perpendicular to the conveying direction of the seedling delivery channel 110. In addition, the above-mentioned seedling delivery channel 110 is preferably arranged horizontally, that is, the seedling delivery channel 110 extends in the horizontal direction, so as to better facilitate the arrangement of the corresponding seedling storage mechanism 200 above the seedling storage and delivery station.

[0050] In this way, the automatic seedling replenishing device 1 provided by the embodiment of the present application, through the above-mentioned structural setting, when the automatic seedling replenishing device 1 is started, the seedlings stored on the seedling storage tray 210 of each seedling storage mechanism 200 can be automatically transported to the seedling delivery channel 110 of the seedling delivery mechanism 100 under the transmission of the second seedling delivery power module 220, and then automatically transported to the planting part of the rice transplanter under the transmission of the first seedling delivery power module 120 of the rice delivery mechanism 100, thereby automatically completing the seedling replenishing operation of the planting part of the rice transplanter. Except for the start-up of the device, the entire seedling replenishing process does not involve too much manual participation, and can greatly improve the working efficiency of the rice transplanter by greatly improving the seedling replenishing efficiency of the planting part of the rice transplanter. It can be seen that this technical solution can effectively improve the technical problem that the existing rice transplanter needs manual labor to perform the seedling replenishing operation of sending the seedlings into the planting part, which seriously affects the working efficiency of the rice transplanter.

[0051] In some examples, such as Figures 1 to 3 As shown, the seedling storage tray 210 is provided with a hollow area (not shown), and a portion of the second seedling delivery power module 220 is disposed in the hollow area and is used to contact the seedlings to drive the seedlings to move. In this way, the second seedling delivery power module 220 can effectively drive the seedlings on the seedling storage tray 210 to be delivered to the seedling delivery channel 110.

[0052] It can be understood that the hollow area mentioned in this example can be specifically set on the bottom surface of the seedling storage trough 211 mentioned below. At this time, the part of the second seedling feeding power module 220 that is set in the hollow area and is used to contact the seedlings to drive the seedlings to move can be specifically the second seedling feeding belt 221 mentioned below.

[0053] In some examples, such as Figures 1 to 3As shown, the limiting guide member 260 includes a transitional docking portion 261 and an arcuate guide portion 262. A first side of the transitional docking portion 261 is abutted against the bottom end of the seedling storage tray 210, while a second side of the transitional docking portion 261 is abutted against the arcuate guide portion 262. The arcuate guide portion 262 prevents the seedlings on the seedling storage tray 210 from falling when the second seedling feeding power module 220 is stationary, and guides the seedlings on the seedling storage tray 210 during operation. This structure allows the limiting guide member 260 to better prevent the seedlings on the seedling storage tray 210 from falling when the second seedling feeding power module 220 is stationary, and to better guide the seedlings on the seedling storage tray 210 during operation. Furthermore, the upper surface of the arcuate guide portion 262, distal from the transitional docking portion 261, forms an angle of less than 30 degrees with the horizontal plane. In this way, the arc-shaped guide portion 262 can better take into account the above-mentioned anti-drop limit function and the above-mentioned conveying guide function. Further, the first side and the second side are respectively two sides of the transition docking portion in the first direction, and the first direction is the length direction of the seedling storage tray. In this way, through the above-mentioned structural setting, the arc-shaped guide part 262 mentioned in this example can specifically form a certain degree of arc-shaped bend in the length direction of the seedling storage tray 210 (that is, the transmission direction of the second seedling feeding power module 220), so as to effectively prevent the seedlings on the seedling storage tray 210 from falling along the length direction of the seedling storage tray 210 when the second seedling feeding power module 220 is stationary through the obstruction formed by the arc-shaped bend. At the same time, this degree of arc-shaped bend can also provide a certain transmission guide for the seedlings on the seedling storage tray 210 when the second seedling feeding power module 220 is running, so that the landing point of the seedlings on the seedling feeding channel 110 is located in front of the bottom end of the seedling storage tray 210 (with the transmission direction of the seedling feeding channel 110 as a reference object), so as to effectively avoid the seedling accumulation phenomenon at the bottom end of the seedling storage tray 210.

[0054] It is understood that the transition docking portion 261 and the arc-shaped guide portion 262 mentioned in this example are specifically integrally formed. This effectively reduces the number of parts in the device and the difficulty of assembling the position-limiting guide 260. In addition, the bottom end of the rice seedling storage tray 210 is provided with a receiving opening (not shown in the figure), and at least a portion of the position-limiting guide 260 is located within the receiving opening. This structural arrangement ensures a tight fit between the position-limiting guide 260 and the bottom end of the rice seedling storage tray 210, making the overall structure more compact.

[0055] In some examples, such as Figure 1 、 Figure 3 and Figure 4As shown, the end of the seedling delivery channel 110 along its delivery direction is provided with a seedling outlet 111, which is used to connect to the planting part of the rice transplanter (not shown). In this way, through the above-mentioned structural arrangement, the first seedling delivery power module can better automatically deliver the seedlings on the seedling delivery channel 110 to the planting part of the rice transplanter through the seedling outlet 111.

[0056] It can be understood that in order to facilitate the rice seedling outlet 111 to be more smoothly connected with the planting part of the rice transplanter, the rice seedling outlet 111 can be specifically set to be inclined. At this time, the rice seedling delivery channel 110 mentioned in this example is provided with a rice seedling outlet 111 at the end along its transmission direction. Specifically, the rice seedling delivery channel 110 is provided with a guide slope at the end along its transmission direction. The outlet of the guide slope (i.e., the rice seedling outlet 111) is located above the planting part of the rice transplanter, so that when the first rice seedling delivery power module 120 drives the seedlings to be delivered to the end along the rice seedling delivery channel 110, the smooth guidance of the guide slope allows these seedlings to be smoothly delivered to the planting part of the rice transplanter.

[0057] In some examples, such as Figure 1 、 Figure 3 and Figure 4 As shown, the seedling delivery channel 110 is sequentially provided with at least one seedling storage and delivery station (not shown) along its conveying direction, and the seedling storage tray 210 is tilted above a seedling storage and delivery station. In this way, the installation and positioning of the seedling storage tray 210 on the seedling delivery channel 110 can be better achieved through the structural arrangement of the seedling storage and delivery station. Furthermore, the present automatic seedling replenishment device 1 may specifically include a plurality of seedling storage mechanisms 200, and the plurality of seedling storage mechanisms 200 are arranged at intervals from each other. In this way, the arrangement of a plurality of seedling storage mechanisms 200 can effectively increase the number of seedlings stored at the same time by the seedling storage mechanisms 200 of the present automatic seedling replenishment device 1, so as to improve the automatic seedling replenishment efficiency of the present automatic seedling replenishment device 1. Furthermore, the inclination angles of the seedling storage trays 210 of the plurality of seedling storage mechanisms 200 relative to the seedling delivery channel 110 are all the same. In this way, through the above-mentioned structural setting, it can be ensured that the seedling delivery rate of each seedling storage mechanism 200 to the seedling delivery channel 110 remains consistent, so as to ensure the automatic seedling replenishment effect of the present automatic seedling replenishment device 1.

[0058] It can be understood that the number of the seedling storage and delivery stations mentioned in this example should be consistent with the number of the seedling storage mechanisms 200, that is, there is a corresponding seedling storage mechanism 200 above each seedling storage and delivery station.

[0059] In some examples, such as Figure 1 、 Figure 3 and Figure 4As shown, a seedling storage trough 211 is recessed on one side of the seedling storage tray 210, and the seedling storage trough 211 is mainly used to store seedlings. The seedling storage mechanism 200 specifically also includes a seedling pressing rack 230, which is movably arranged in the second direction on the notch side of the seedling storage trough 211 to be used for pressing and limiting the seedlings in the seedling storage trough 211 in the second direction, and the second direction is perpendicular to the bottom surface of the trough of the seedling storage trough 211. In this way, the structural setting of the seedling pressing rack 230 can effectively prevent the seedlings stored in the seedling storage trough 211 from falling down through the notch side of the seedling storage trough 211 under the action of gravity due to the tilted setting of the seedling storage tray 210.

[0060] It can be understood that the trough wall on one side of the bottom end of the seedling storage tray 210 corresponding to the seedling storage trough 211 mentioned in this example should be hollowed out to leave an outlet for docking with the limiting guide, so that the seedlings stored in the seedling storage trough 211 can be transported by the second seedling delivery power module 220, come out through the outlet and be transported to the seedling delivery channel 110 through the limiting guide. The seedling pressing rack 230 mentioned in this example is movably arranged on the notch side of the seedling storage trough 211 in the second direction, which specifically means that the seedling pressing rack 230 is movably arranged on the notch side of the seedling storage trough 211, and the distance between the seedling pressing rack 230 and the bottom surface of the trough of the seedling storage trough 211 in the second direction is adjustable. In this way, the user can adjust the distance at any time according to the actual number of seedlings that the seedling storage trough 211 needs to store, so as to meet the user's needs for storing different numbers of seedlings in the seedling storage trough 211.

[0061] In some examples, such as Figure 1 、 Figure 3 and Figure 4As shown, the seedling storage mechanism 200 specifically includes a first mounting bracket 240 and a second mounting bracket 250, which are spaced apart along the length of the seedling storage trough 211. The first mounting bracket 240 includes two first mounting rods 241, which are fixed to opposite sides of the seedling storage trough 211 in the width direction. Each first mounting rod 241 has a plurality of first mounting holes 242 defined along the second direction. The plurality of first mounting holes 242 of the two first mounting rods 241 correspond to each other. One end of the seedling pressing frame 230 is mounted and fixed through any pair of first mounting holes 242 of the two first mounting rods 241. The second mounting bracket 250 includes two second mounting rods 251, which are positioned on opposite sides of the seedling storage trough 211 in the width direction. Each second mounting rod 251 is movable in the second direction relative to the corresponding side of the seedling storage trough 211. The other end of the seedling pressing frame 230 is mounted and fixed to the two second mounting rods 251. Thus, through the above-mentioned structural arrangement, it is possible to well realize that the seedling pressing frame 230 is movably arranged in the second direction on the notch side of the seedling storage trough 211. At the same time, because the two ends of the seedling pressing frame 230 are movably connected to the seedling storage trough 211 in the second direction through different movable structures, when the user stores different numbers of seedlings in the seedling storage trough 211, the two ends of the seedling pressing frame 230 can be adjusted to different movements in the second direction according to the actual limiting requirements in the second direction, so as to better meet the limiting requirements of the corresponding seedlings in the seedling storage trough 211.

[0062] It is understood that in this example, each first mounting rod 241 should extend along the second direction so that it can better define multiple first mounting holes 242 in sequence along the second direction. At the same time, since the first mounting bracket 240 is primarily mounted on the top of the seedling storage tray 210, and the seedlings are primarily stored in the corresponding seedling storage trough 211 from this end, the movable adjustment of one end of the seedling pressing rack 230 movably connected thereto in the second direction should be flexible and convenient. Therefore, the multiple first mounting holes 242 can be specifically configured as side openings. At the same time, a side locking rod 243 is rotatably provided. By rotating the side locking rod 243 clockwise or counterclockwise, the side openings of the multiple first mounting holes 242 on the same side can be switched back and forth between open and closed. In this way, one end of the seedling pressing rack 230 can be quickly locked into any pair of first mounting holes 242 of the two first mounting rods 241 and then quickly installed and fixed by the side locking rod 243. In addition, the movable setting of each second mounting rod and the corresponding side of the rice seedling storage trough 211 mentioned in this example in the second direction can be specifically achieved through the following structure, each second mounting rod is also extended along the second direction, and each second mounting rod is provided with a second mounting hole 252, the second mounting hole 252 is specifically a long hole structure, and the long hole structure is specifically extended along the second direction. In this way, the corresponding second mounting rod can be installed and fixed on the corresponding side of the rice seedling storage trough 211 through the second mounting hole 252 at any position in the second direction, so that the corresponding second mounting rod and the corresponding side of the rice seedling storage trough 211 can be well realized to be movable in the second direction.

[0063] In some examples, such as Figures 1 to 4 As shown, the rice pressing rack 230 may specifically include a first connecting rod 231, a second connecting rod 232, and a plurality of rice pressing rods 233. Each rice pressing rod 233 has one end bent to form a first bent portion, and the other end bent to form a second bent portion. The first connecting rod 231 connects the first bent portions of the plurality of rice pressing rods 233 together, and the two ends of the first connecting rod 231 are mounted and fixed through either pair of first mounting holes 242 of the two first mounting rods 241. The second connecting rod 232 connects the second bent portions of the plurality of rice pressing rods 233 together, and the two ends of the second connecting rod 232 are mounted and fixed to the two second mounting rods 251. This structural arrangement ensures that the rice pressing rack 230 in this example can effectively press and limit the rice seedlings in the rice seedling storage trough 211 in the second direction, while also making its overall structure more lightweight and simple.

[0064] It can be understood that the multiple seedling pressing rods 233 in this example are all extended along the length direction of the seedling storage trough 211, and the multiple seedling pressing rods 233 are arranged at equal intervals, so that the seedling pressing rack 230 composed of the multiple seedling pressing rods 233 can well press and limit the seedlings in the seedling storage trough 211 in the second direction. In addition, the rice pressing rack 230 in this example also includes multiple height-adjusting rods 234, at least one height-adjusting rod 234 is movably set between the first bending parts of the multiple rice pressing rods 233, and at least one height-adjusting rod 234 is movably set between the second bending parts of the multiple rice pressing rods 233. In this way, when the rice pressing rack 230 is movably set on the slot side of the rice storage trough 211, the height of each height-adjusting rod 234 (that is, the vertical distance between it and the trough surface of the rice storage trough 211) is adjustable, so that it can adjust the height of the corresponding height-adjusting rod 234 at any time according to the different heights of the seedlings placed in the rice storage trough 211, so as to achieve the purpose of clamping the leaf part of the seedlings while not hindering the seedlings from sliding down smoothly due to the height being too low.

[0065] In some examples, such as Figures 1 to 3 As shown, the second seedling-feeding power module 220 may include a second seedling-feeding belt 221 movably mounted on the bottom surface of the seedling storage trough 211. The second seedling-feeding belt 221 is provided with a plurality of hook teeth 222 arranged in an array on the surface of the first seedling-feeding belt 121. With this structural arrangement, when the second seedling-feeding power module 220 is not operating, i.e., when the second seedling-feeding belt 221 is not rotating, the hook teeth 222 provide a barrier to further prevent the seedlings on the seedling storage tray 210 from falling. When the second seedling-feeding power module 220 is operating, i.e., when the second seedling-feeding belt 221 is rotating, the hook teeth 222 provide sufficient traction to the seedlings on the seedling storage tray 210, thereby driving the seedlings on the seedling storage tray 210 to be transported to the seedling-feeding channel 110.

[0066] It can be understood that the second seedling sending power module 220 in this example specifically also includes a motor power structure 223 that drives the second seedling sending belt 221 to perform a conveying operation. The motor power structure 223 is driven by a servo motor and cooperates with the transmission of the transmission wheel and the transmission belt to drive the second seedling sending belt 221 to perform a circular motion, so that the second seedling sending belt 221 performs a conveying operation through the circular motion to drive the seedlings to convey the seedlings on the seedling storage tray 210 to the seedling sending material channel 110.

[0067] In some examples, such as Figure 2 and Figure 3As shown, the automatic rice seedling replenishing device 1 further includes a third mounting bracket 300. Each third mounting bracket 300 includes two third mounting rods 310. The two third mounting rods 310 are respectively fixed on two opposite sides in the width direction of the rice seedling feeding channel 110. The first ends of the rice seedling storage trays 210 are respectively fixedly mounted at an angle on the two third mounting rods 310. In this way, the structural arrangement of the third mounting brackets 300 can effectively achieve the inclined arrangement of the rice seedling storage trays 210 above the rice seedling feeding channel 110.

[0068] It should be understood that the first end of the seedling storage tray 210 mentioned in this example specifically refers to the end of the seedling storage tray 210 adjacent to the seedling delivery channel 110, i.e., the bottom end of the seedling storage tray 210 mentioned above. In this example, the first end of the seedling storage tray 210 being obliquely mounted and fixed to two third mounting rods 310 specifically refers to the first end being obliquely mounted and fixed to corresponding third mounting rods 310 on opposite sides of the seedling storage tray 210 in the width direction. This mounting and fixing method can specifically be a locking method such as screws, snaps, or welding, so that the seedling storage tray 210 is tilted at a certain angle above the seedling delivery channel 110. Furthermore, when there are multiple seedling storage mechanisms 200, the number of third mounting brackets 300 and the number of seedling storage and delivery stations mentioned above are also multiple, and the number of these brackets is consistent with the number of seedling storage mechanisms 200. Each seedling storage mechanism 200 is mounted and fixed to one of the third mounting brackets 300 to achieve an oblique angle above the corresponding seedling storage and delivery station.

[0069] In some examples, such as Figures 1 to 3 As shown, the automatic rice seedling replenishing device 1 further includes a support rod assembly 400, which includes two support rod bodies 410. The two support rod bodies 410 are respectively arranged on two opposite sides in the width direction of the rice seedling feeding channel 110, and one end of the support rod body 410 and the corresponding side of the rice seedling feeding channel 110 are movably arranged in the conveying direction of the rice seedling feeding channel 110, and the other end of the support rod body 410 is fixedly mounted on the second end of the rice seedling storage tray 210. In this way, through the structural arrangement of the above-mentioned support rod assembly 400, by providing auxiliary support to the second end of the rice seedling storage tray 210, in conjunction with the structural arrangement of the third mounting bracket 300 in the previous example, it is further ensured that the rice seedling storage tray 210 can be stably arranged at an angle above the rice seedling feeding channel 110.

[0070] It can be understood that the second end of the seedling storage tray 210 mentioned in this example specifically refers to the end of the seedling storage tray 210 away from the seedling feeding channel 110, that is, the top end of the seedling storage tray 210 mentioned above.

[0071] In some examples, such as Figures 1 to 3As shown, the third mounting rod 310 is provided with a plurality of third mounting holes 320 sequentially formed along the third direction. The plurality of third mounting holes 320 of the two third mounting rods 310 are provided in a one-to-one correspondence. The first end of the rice seedling storage tray 210 is respectively and obliquely mounted and fixed on the two third mounting rods 310 through any pair of third mounting holes 320 of the two third mounting rods 310. Thus, through the above-mentioned structural arrangement, the first end of the rice seedling storage tray 210 can be obliquely mounted and fixed through any pair of third mounting holes 320 sequentially provided along the third direction on the two third mounting rods 310. In addition, since the second end of the seedling storage tray 210 is auxiliary supported by a support rod assembly 400, and one end of each support rod body 410 of the support rod assembly 400 is movably arranged on the corresponding side of the seedling delivery channel 110 in the conveying direction of the seedling delivery channel 110, the inclination angle of the seedling storage tray 210 can be adaptively adjusted according to the actual seedling delivery effect requirements of the seedling storage mechanism 200. The specific angle adjustment range is 45° to 90°. In this way, it can be ensured that the inclination angle of the seedling storage tray 210 can better meet the various actual seedling delivery effect requirements of the seedling storage mechanism 200.

[0072] In some examples, such as Figures 1 to 3 As shown, a plurality of movable mounting holes 112 are respectively provided on two opposite sides in the width direction of the seedling feeding channel 110, and the plurality of movable mounting holes 112 on the same side are sequentially arranged along the conveying direction of the seedling feeding channel 110. One end of the support rod body 410 is fastened to the corresponding side of the seedling feeding channel 110 through any movable mounting hole 112 on the corresponding side, so as to realize that one end of the support rod body 410 and the corresponding side of the seedling feeding channel 110 can be movably arranged in the conveying direction of the seedling feeding channel 110. In this way, by fixing one end of the corresponding support rod body 410 to the corresponding side of the seedling feeding channel 110 through any movable mounting hole 112 in the conveying direction of the seedling feeding channel 110, the movable arrangement of one end of the corresponding support rod body 410 and the corresponding side of the seedling feeding channel 110 in the conveying direction of the seedling feeding channel 110 can be well realized.

[0073] In some examples, such as Figures 1 to 3As shown, the automatic seedling replenishing device 1 specifically includes a plurality of seedling storage mechanisms 200. The automatic seedling replenishing device 1 specifically also includes a connecting rod assembly 500. The seedling storage trays 210 of two adjacent seedling storage mechanisms 200 are fastened together by a connecting rod assembly 500, so that the seedling storage trays 210 of the plurality of seedling storage mechanisms 200 are fastened together. In this way, through the above-mentioned structural setting, it can be well ensured that the seedling storage trays 210 of multiple seedling storage mechanisms 200 are each inclined at the same angle above the corresponding seedling storage and seedling delivery stations. At the same time, since the connecting rod assembly 500 fastens the multiple seedling storage mechanisms 200 together, the inclination angle of the seedling storage tray 210 of one of the seedling storage mechanisms 200 can be adaptively adjusted according to the actual seedling delivery effect requirements of the seedling storage mechanism 200. At the same time, the inclination angles of the seedling storage trays 210 of other seedling storage mechanisms 200 can also be adjusted synchronously therewith. That is, only one support rod assembly 100 is required to tiltly support the second end of the seedling storage tray 210 of one of the seedling storage mechanisms 200, so that the inclination angle adjustment of all the seedling storage trays 210 can be achieved synchronously, so as to ensure that the inclination angles of all the seedling storage trays 210 can better meet the various actual seedling delivery effect requirements of the seedling storage mechanism 200.

[0074] It can be understood that the number of connecting rod assemblies 500 mentioned in this example should be one less than the number of seedling storage mechanisms 200. At the same time, each connecting rod assembly 500 should include at least two third connecting rod bodies 510. The two third connecting rod bodies 510 should be arranged opposite to each other in the width direction of the seedling feeding channel 110, and the two ends of each third connecting rod body 510 are respectively fastened to the top of a seedling storage tray 210 of a seedling storage mechanism 200 to better ensure that the seedling storage trays 210 of all seedling storage mechanisms 200 of the automatic seedling replenishing device 1 in this example are connected together and can be adjusted to the tilt angle synchronously.

[0075] In some examples, such as Figures 1 to 4 As shown, the transmission speed of the second seedling-feeding power module 220 is lower than that of the first seedling-feeding power module 120. In this way, through the above-mentioned structural arrangement, when the second seedling-feeding power module 220 transmits the corresponding seedlings on the seedling storage tray 210 to the seedling-feeding material channel 110, when the front ends of these seedlings contact the first seedling-feeding power module 120 on the seedling-feeding material channel 110, due to the faster transmission speed of the first seedling-feeding power module 120, the seedlings will be tightened and sent forward, and will not accumulate on the seedling-feeding material channel 110 below, until the rear ends of the seedlings leave the second seedling-feeding power module 220. The complete seedlings are then sent from the seedling-feeding material channel 110 below to the transplanting part of the rice transplanter, so as to better complete the entire automated seedling-replenishing action and ensure its seedling-replenishing effect.

[0076] It is understood that the first seedling-feeding power module 120 in this example may specifically include a conveyor belt and a motor power structure (not shown) that drives the first seedling-feeding belt 121 for conveying operation. The motor power structure is driven by a servo motor, which cooperates with the transmission of the transmission wheel and the transmission belt to drive the first seedling-feeding belt 121 to perform a circular motion, so that the first seedling-feeding belt 121 performs a conveying operation through this circular motion, thereby driving the seedlings to be transported along the seedling-feeding material path 110. Therefore, the aforementioned front ends of the seedlings contacting the first seedling-feeding power module 120 on the seedling-feeding material path 110 specifically refers to the front ends of the seedlings contacting the first seedling-feeding belt 121 on the seedling-feeding material path 110. In addition, the surface of the first seedling-feeding belt 121 mentioned above may also be provided with a plurality of hook teeth 222, and the plurality of hook teeth 222 are arranged in an array on the surface of the first seedling-feeding belt 121. In this way, when the first seedling feeding power module 120 is working, that is, when the first seedling feeding belt 121 rotates, the hook teeth 222 can provide sufficient traction to the seedlings on the seedling feeding channel 110 to drive the seedlings on the seedling feeding channel 110 to be transferred to the planting part of the rice transplanter.

[0077] In some examples, the automatic seedling replenishment device 1 further includes a triggering and starting mechanism, which is electrically connected to the seedling delivery mechanism 100 and at least one seedling storage mechanism 200, and a switch of the triggering and starting mechanism is provided on the seedling tray of the planting part, so as to automatically start the seedling delivery mechanism 100 and at least one seedling storage mechanism 200 when the seedlings on the seedling tray of the planting part are less than a preset number. In this way, by interactively setting the signal with the triggering and starting mechanism, when the seedlings in the planting part of the rice transplanter are insufficient, the triggering signal can automatically replenish the seedlings from the seedling storage and the seedling delivery mechanism 100, which greatly improves the working efficiency, reduces the labor intensity and reduces the labor cost and time cost, and also plays a great role in promoting the development of fully automated and unmanned rice transplanters. Through these advanced scientific and technological means, the automation, precision and intelligence of farmland operations are realized, which has brought revolutionary changes to agricultural production.

[0078] It can be understood that the trigger starting mechanism in this example can specifically adopt the following structural setting, that is, a hollow position is set on the seedling tray of the planting part of the rice transplanter, and a limit sensor is set at the hollow position for residual material detection. The limit sensor has a little elasticity so that it protrudes from the hollow position to the surface of the seedling tray. When there are a sufficient number of seedlings on the seedling tray, the seedlings will come to the hollow position and press the limit sensor. At this time, it is judged that there are sufficient seedlings on the seedling tray; and when the seedlings on the seedling tray are less than the preset number, no seedlings come to the hollow position to press the limit sensor. At this time, it is judged that there are insufficient seedlings on the seedling tray, and the seedling delivery mechanism 100 and at least one seedling storage mechanism 200 should be started in time to automatically replenish the seedlings. Those skilled in the art will appreciate that the aforementioned limit sensors can also be replaced by photoelectric sensors to detect the number of seedlings in the seedling tray. In this case, when there are a sufficient number of seedlings on the seedling tray, some seedlings will move to the hollowed-out position and block the light beam of the photoelectric sensor, indicating that the seedling tray has sufficient seedlings. When there are fewer than a preset number of seedlings on the seedling tray, no seedlings will move to the hollowed-out position to block the light beam of the photoelectric sensor, indicating that the seedling tray is insufficient. The seedling delivery mechanism 100 and the at least one seedling storage mechanism 200 should be activated promptly to automatically replenish the seedlings. A weight sensor can also be used to detect excess material in this example. This weight sensor is located on the bottom side of the seedling tray to monitor the weight of the tray in real time. If the weight is lower than a preset value, it indicates that there are fewer than the preset number of seedlings on the seedling tray, i.e., insufficient seedlings on the seedling tray. The seedling delivery mechanism 100 and the at least one seedling storage mechanism 200 should be activated promptly to automatically replenish the seedlings. In addition, a visual system can also be used to detect residual material in this example. The visual system specifically includes a camera and an image processing system to accurately detect whether the number of seedlings in the seedling tray is less than a preset number through image recognition technology.
