[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, motion condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0046] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection claimed by the present application.

[0047] In one embodiment, asFigures 1 to 4 As shown, the embodiment of the present application also provides a seedling automatic supplement device 1, which can specifically include a seedling feeding mechanism 100 and a seedling storage mechanism 200. The seedling feeding mechanism 100 can specifically include a seedling feeding channel 110 and a first seedling feeding power module 120 for driving the seedlings to be conveyed along the seedling feeding channel 110. The seedling storage mechanism 200 can specifically include a seedling storage tray 210, a second seedling feeding power module 220, and a limiting guide 260. The seedling storage tray 210 is obliquely arranged above the seedling feeding channel 110, and the second seedling feeding power module 220 is movably arranged on the seedling storage tray 210 to drive the seedlings on the seedling storage tray 210 to be conveyed to the seedling feeding 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 seedlings on the seedling storage tray 210 to be conveyed when the second seedling feeding power module 220 is running, so as to cooperate with the second seedling feeding power module 220 to convey the seedlings on the seedling storage tray 210 to the seedling feeding channel 110.

[0048] It can be understood that the seedling automatic supplement device 1 of the embodiment of the present application can be applied to the automatic seedling feeding operation of the rice transplanter, that is, when the seedling feeding part of the rice transplanter is short of seedlings (specifically less than a preset number), the seedlings stored in the seedling automatic supplement device 1 are automatically fed into the seedling feeding part of the rice transplanter. Therefore, the seedling automatic supplement device 1 of the embodiment of the present application can be designed separately to be directly mounted on the rice transplanter on the market for use, or directly used as a mechanism of the rice transplanter to be added to any type of existing rice transplanter to form a new rice transplanter for use. The bottom end of the seedling storage tray 210 mentioned above specifically refers to one end of the seedling storage tray 210 adjacent to the seedling feeding channel 110, and the top end of the seedling storage tray 210 mentioned below specifically refers to one end of the seedling storage tray 210 away from the seedling feeding channel 110. The limiting guide 260 mentioned above prevents the seedlings on the seedling storage tray 210 from falling when the second seedling feeding power module 220 is stationary, which specifically refers to that when the second seedling feeding power module 220 is not started, the structure (such as an arc-shaped bending) of the second seedling feeding power module 220 itself can form an obstruction in the conveying direction of the second seedling feeding power module 220 to prevent the seedlings on the seedling storage tray 210 from falling onto the seedling feeding channel 110 due to the oblique arrangement of the seedling storage tray 210 under the action of gravity. Therefore, the limiting guide 260 can be a limiting guide plate or other structure that can realize the above-mentioned falling prevention and conveying guidance functions.

[0049] In addition, the oblique arrangement of the seedling storage tray 210 above the seedling feeding channel 110 can be achieved by Figure 1As shown, the width direction of the seedling storage tray 210 is perpendicular to the conveying direction of the seedling conveying path 110, so that the rolling seedling conveying structure 220 can better convey the seedlings to the seedling conveying path 110 along the direction along the conveying direction of the seedling conveying path 110. Alternatively, the width direction of the seedling storage tray 210 is parallel to the conveying direction of the seedling conveying path 110, so that the rolling seedling conveying structure 220 can convey the seedlings to the seedling conveying path 110 along the direction perpendicular to the conveying direction of the seedling conveying path 110 on either side of the width direction of the seedling conveying path 110. In addition, the seedling conveying path 110 mentioned above is preferably horizontally arranged, that is, the seedling conveying path 110 extends in the horizontal direction, so as to better arrange the corresponding seedling storage mechanism 200 above the seedling storage and conveying station.

[0050] In this way, the seedling automatic replenishing device 1 provided by the embodiment of the present application can automatically convey the seedlings stored on the seedling storage tray 210 of each seedling storage mechanism 200 to the seedling conveying path 110 of the seedling conveying mechanism 100 under the conveying of the second seedling conveying power module 220 when the seedling automatic replenishing device 1 is started, and then automatically convey the seedlings to the planting part of the rice transplanter under the conveying of the first seedling conveying power module 120 of the seedling conveying mechanism 100, thereby automatically completing the seedling replenishing operation on the planting part of the rice transplanter. The entire seedling replenishing process does not involve excessive manual participation except for the start of the device, and the work efficiency of the rice transplanter can be greatly improved by greatly improving the seedling replenishing efficiency of the planting part of the rice transplanter. It can be seen that the technical solution can effectively improve the technical problem that the existing rice transplanter needs manual seedling conveying to the planting part, which seriously affects the work efficiency of the rice transplanter.

[0051] In some examples, as shown in the drawings, the seedling storage tray 210 is provided with a hollow area (not shown), and part of the second seedling conveying power module 220 is arranged in the hollow area and used to contact the seedlings to drive the seedlings to move. In this way, the seedlings on the seedling storage tray 210 can be conveyed to the seedling conveying path 110 by the second seedling conveying power module 220. Figures 1 to 3

[0052] It can be understood that the hollow area mentioned in the present example can be arranged on the groove bottom surface of the seedling storage groove body 211 mentioned below, and at this time, the part of the second seedling conveying power module 220 arranged in the hollow area and used to contact the seedlings to drive the seedlings to move can be the second seedling conveying belt 221 mentioned below.

[0053] In some examples, as shown in the drawings, the seedling storage tray 210 is provided with a hollow area (not shown), and part of the second seedling conveying power module 220 is arranged in the hollow area and used to contact the seedlings to drive the seedlings to move. In this way, the seedlings on the seedling storage tray 210 can be conveyed to the seedling conveying path 110 by the second seedling conveying power module 220. Figures 1 to 3 ​As shown, the limiting and guiding member 260 comprises a transition joint portion 261 and an arc-shaped guiding portion 262. The first side of the transition joint portion 261 is in abutment with the bottom end of the seedling storage tray 210, and the second side of the transition joint portion 261 is in abutment with the arc-shaped guiding portion 262. The arc-shaped guiding portion 262 prevents the seedlings on the seedling storage tray 210 from falling when the second seedling conveying power module 220 is stationary, and guides the seedlings on the seedling storage tray 210 when the second seedling conveying power module 220 is in operation. Thus, the above structure can better prevent the seedlings on the seedling storage tray 210 from falling when the second seedling conveying power module 220 is stationary, and better guide the seedlings on the seedling storage tray 210 when the second seedling conveying power module 220 is in operation. Further, the angle between the upper surface of the end of the arc-shaped guiding portion 262 away from the transition joint portion 261 and the horizontal plane is less than 30 degrees. Thus, the arc-shaped guiding portion 262 can better simultaneously achieve the above-mentioned functions. Further, the first side and the second side are respectively the two sides of the transition joint portion in the first direction, which is the length direction of the seedling storage tray. Thus, the arc-shaped guiding portion 262 in the present example can be bent in the length direction of the seedling storage tray 210 (i.e., the conveying direction of the second seedling conveying power module 220). When the second seedling conveying power module 220 is stationary, the seedlings on the seedling storage tray 210 are effectively prevented from falling along the length direction of the seedling storage tray 210. Meanwhile, the degree of bending of the arc-shaped guiding portion 262 can guide the seedlings on the seedling storage tray 210 when the second seedling conveying power module 220 is in operation, so that the seedlings fall on the seedling conveying path 110 in front of the bottom end of the seedling storage tray 210 (with reference to the conveying direction of the seedling conveying path 110), thereby effectively preventing the seedlings from accumulating at the bottom end of the seedling storage tray 210.

[0054] It can be understood that the transition joint portion 261 and the arc-shaped guiding portion 262 in the present example are integrally formed. Thus, the number of parts of the device can be effectively reduced, and the assembly difficulty of the limiting and guiding member 260 can be effectively reduced. In addition, the bottom end of the seedling storage tray 210 is provided with a receiving opening (not shown in the figure), and at least part of the limiting and guiding member 260 is located in the receiving opening. Thus, the close fit between the limiting and guiding member 260 and the bottom end of the seedling storage tray 210 can be ensured, and the overall structure can be more compact.

[0055] In some examples, as Figure 1 , Figure 3 and Figure 4As shown, the end of the seedling conveying path 110 along its conveying direction is provided with a seedling outlet 111, which is used to dock the planting part (not shown) of the seedling planter. In this way, the above structure can be set so that the first seedling conveying power module can better automatically convey the seedlings on the seedling conveying path 110 to the planting part of the seedling planter through the seedling outlet 111.

[0056] It can be understood that, in order to facilitate the seedling outlet 111 to dock the planting part of the seedling planter more smoothly, the seedling outlet 111 can be specifically inclined, and at this time, the end of the seedling conveying path 110 along its conveying direction in the example mentioned above is specifically provided with a guide slope at the end of the seedling conveying path 110 along its conveying direction. The outlet of the guide slope, i.e., the seedling outlet 111, is located above the planting part of the seedling planter, so that when the first seedling conveying power module 120 drives the seedlings to convey to the end along the seedling conveying path 110, the smooth guidance of the guide slope can make the seedlings smoothly enter the planting part of the seedling planter.

[0057] In some examples, as shown in Figure 1 , Figure 3 and Figure 4 , the seedling conveying path 110 is sequentially provided with at least one seedling storage and conveying station (not shown) along its conveying direction, and the seedling storage tray 210 is inclinedly arranged above a seedling storage and conveying station. In this way, the structure of the seedling storage and conveying station can better realize the installation and positioning of the seedling storage tray 210 on the seedling conveying path 110. Further, the present automatic seedling supplementing device 1 can specifically include a plurality of seedling storage mechanisms 200, and the plurality of seedling storage mechanisms 200 are arranged at intervals. In this way, the number of seedlings stored by the seedling storage mechanism 200 of the present automatic seedling supplementing device 1 at the same time can be effectively improved by the arrangement of the plurality of seedling storage mechanisms 200, so as to improve the automatic seedling supplementing efficiency of the present automatic seedling supplementing device 1. Further, the inclination angles of the seedling storage trays 210 of the plurality of seedling storage mechanisms 200 relative to the seedling conveying path 110 are the same. In this way, the above structure can ensure that the seedling conveying rate of each seedling storage mechanism 200 to the seedling conveying path 110 remains consistent, so as to ensure the automatic seedling supplementing effect of the present automatic seedling supplementing device 1.

[0058] It can be understood that the number of seedling storage and conveying stations mentioned in the example should be consistent with the number of seedling storage mechanisms 200, that is, one seedling storage mechanism 200 is arranged above each seedling storage and conveying station.

[0059] In some examples, as shown in Figure 1 , Figure 3 and Figure 4As shown, one side of the seedling storage tray 210 is recessed with a seedling storage groove body 211, which is mainly used for storing seedlings. The seedling storage mechanism 200 further includes a seedling pressing frame 230, which is movably arranged at the groove opening side of the seedling storage groove body 211 in the second direction, so as to limit the seedlings in the seedling storage groove body 211 in the second direction, which is perpendicular to the groove bottom surface of the seedling storage groove body 211. In this way, the structure of the seedling pressing frame 230 can effectively prevent the seedlings stored in the seedling storage groove body 211 from falling down through the groove opening side of the seedling storage groove body 211 due to the inclination of the seedling storage tray 210 under the action of gravity.

[0060] It can be understood that the side groove wall of the bottom end of the seedling storage groove body 211 corresponding to the seedling storage tray 210 in the present example should be hollowed out to leave an outlet to connect with the limiting guide piece, so that the seedlings stored in the seedling storage groove body 211 can be conveyed out through the outlet and conveyed to the seedling conveying channel 110 through the limiting guide piece under the conveying of the second seedling conveying power module 220. The seedling pressing frame 230 movably arranged at the groove opening side of the seedling storage groove body 211 in the second direction in the present example means that the seedling pressing frame 230 is movably arranged at the groove opening side of the seedling storage groove body 211, and the distance between the seedling pressing frame 230 and the groove bottom surface of the seedling storage groove body 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 to be stored in the seedling storage groove body 211, so as to meet the user's demand for storing different numbers of seedlings in the seedling storage groove body 211.

[0061] In some examples, as Figure 1 , Figure 3 and Figure 4As shown, the seedling storage mechanism 200 further comprises a first mounting bracket 240 and a second mounting bracket 250, which are arranged at intervals in the length direction of the seedling storage groove body 211. The first mounting bracket 240 comprises two first mounting rod bodies 241, which are respectively fixedly arranged on the two opposite sides in the width direction of the seedling storage groove body 211. Each first mounting rod body 241 is sequentially provided with a plurality of first mounting holes 242 in the second direction, and the first mounting holes 242 of the two first mounting rod bodies 241 are arranged one by one in correspondence. One end of the seedling pressing frame 230 is installed and fixed through any pair of first mounting holes 242 of the two first mounting rod bodies 241. The second mounting bracket 250 comprises two second mounting rod bodies 251, which are respectively arranged on the two opposite sides in the width direction of the seedling storage groove body 211, and each second mounting rod is movably arranged on the corresponding side of the seedling storage groove body 211 in the second direction. The other end of the seedling pressing frame 230 is installed and fixed on the two second mounting rod bodies 251. In this way, through the above structural arrangement, the seedling pressing frame 230 can be movably arranged on the groove side of the seedling storage groove body 211 in the second direction. At the same time, since the two ends of the seedling pressing frame 230 are movably connected with the seedling storage groove body 211 in the second direction through different movable structures, when the user stores different quantities of seedlings in the seedling storage groove body 211, the two ends of the seedling pressing frame 230 can be movably adjusted in the second direction according to the actual limiting requirement in the second direction, so as to better meet the limiting requirement of the corresponding seedlings in the seedling storage groove body 211.

[0062] It is understandable that each first mounting rod 241 in this example should extend along the second direction to facilitate the sequential opening of multiple first mounting holes 242 along the second direction. Meanwhile, since the first mounting bracket 240 is mainly installed at the top of the seedling tray 210, and the seedlings are mainly stored from this end into the corresponding seedling trough 211, the adjustment of one end of the movably connected pressing frame 230 in the second direction should prioritize flexibility and convenience. Therefore, the multiple first mounting holes 242 can all adopt a side-opening structure. Simultaneously, a side locking rod 243 is rotatably provided, allowing the side openings of the multiple first mounting holes 242 on the same side to switch between opening and closing by rotating the side locking rod 243 clockwise or counterclockwise. In this way, one end of the pressing frame 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. Furthermore, the movable arrangement of each second mounting rod and the corresponding side of the seedling storage trough 211 in the second direction mentioned in this example can be achieved through the following structure: each second mounting rod also extends along the second direction, and each second mounting rod has a second mounting hole 252. The second mounting hole 252 is specifically an elongated hole structure that extends along the second direction. In this way, by installing and fixing the corresponding second mounting rod to the corresponding side of the seedling storage trough 211 at any position in the second direction through the second mounting hole 252, the movable arrangement of the corresponding second mounting rod and the corresponding side of the seedling storage trough 211 in the second direction can be well achieved.

[0063] In some examples, such as Figures 1 to 4 As shown, the seedling pressing frame 230 specifically includes a first connecting rod 231, a second connecting rod 232, and multiple pressing rods 233. One end of each pressing rod 233 is bent to form a first bend, and the other end of each pressing rod 233 is bent to form a second bend. The first connecting rod 231 connects the first bends of the multiple pressing rods 233 together, and both ends of the first connecting rod 231 are fixed and installed through any pair of first mounting holes 242 of the two first mounting rods 241. The second connecting rod 232 connects the second bends of the multiple pressing rods 233 together, and both ends of the second connecting rod 232 are fixed and installed on the two second mounting rods 251. In this way, through the above structural setting, it is ensured that the seedling pressing frame 230 in this example can effectively press and limit the seedlings in the seedling storage trough 211 in the second direction, while making its overall structure lighter and simpler.

[0064] It can be understood that the plurality of seedling pressing rod bodies 233 in the example extend along the length direction of the seedling storage groove body 211, and are arranged at equal intervals, so that the seedling pressing frame 230 formed by the plurality of seedling pressing rod bodies 233 can well limit the seedlings in the seedling storage groove body 211 in the second direction. In addition, the seedling pressing frame 230 in the example further includes a plurality of height adjusting rod bodies 234, at least one height adjusting rod body 234 is movably arranged between the first bending portions of the plurality of seedling pressing rod bodies 233, and at least one height adjusting rod body 234 is movably arranged between the second bending portions of the plurality of seedling pressing rod bodies 233. Thus, when the seedling pressing frame 230 is movably arranged at the groove side of the seedling storage groove body 211, the height (i.e., the vertical distance between the height adjusting rod body 234 and the groove surface of the seedling storage groove body 211) of each height adjusting rod body 234 can be adjusted, so that the height of the corresponding height adjusting rod body 234 can be adjusted at any time according to the different heights of the seedlings placed in the seedling storage groove body 211, so as to achieve the purpose of being able to clamp the leaf part of the seedlings without hindering the smooth sliding of the seedlings due to the too low height.

[0065] In some examples, as shown in Figures 1 to 3 The second seedling conveying power module 220 specifically includes a second seedling conveying belt 221 movably arranged at the groove bottom surface of the seedling storage groove body 211, the surface of the second seedling conveying belt 221 is 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 conveying belt 121. Thus, through the above structure, when the second seedling conveying power module 220 is not working, the second seedling conveying belt 221 is not running, that is, it is static, and the seedlings on the seedling storage tray 210 can be further prevented from falling by the blocking of the plurality of hook teeth 222. When the second seedling conveying power module 220 is working, that is, the second seedling conveying belt 221 is rotating, the plurality of hook teeth 222 can provide sufficient traction to the seedlings on the seedling storage tray 210 to convey the seedlings on the seedling storage tray 210 to the seedling conveying channel 110.

[0066] It can be understood that the second seedling conveying power module 220 in the example further includes a motor power structure 223 for driving the second seedling conveying belt 221 to run. The motor power structure 223 is driven by a servo motor, cooperates with a transmission wheel and a transmission belt to drive the second seedling conveying belt 221 to run in a cycle, so that the second seedling conveying belt 221 runs in the cycle to convey the seedlings on the seedling storage tray 210 to the seedling conveying channel 110.

[0067] In some examples, as shown in Figure 2 and Figure 3As shown, the automatic seedling supplementing device 1 further comprises third mounting supports 300, each of which comprises two third mounting rods 310, which are respectively fixedly arranged on two opposite sides in the width direction of the seedling conveying channel 110, and the first end of the seedling storage tray 210 is respectively fixedly arranged on the two third mounting rods 310. In this way, the third mounting supports 300 are arranged, and the seedling storage tray 210 can be arranged in an inclined manner above the seedling conveying channel 110.

[0068] It can be understood that the first end of the seedling storage tray 210 mentioned in the example refers to the end of the seedling storage tray 210 adjacent to the seedling conveying channel 110, i.e., the bottom end of the seedling storage tray 210 mentioned above. The first end of the seedling storage tray 210 mentioned in the example is respectively fixedly arranged on the two third mounting rods 310, which means that the first end is respectively fixedly arranged on a corresponding third mounting rod 310 on the two opposite sides in the width direction of the seedling storage tray 210. The fixing manner can be screwing, buckling, or welding, etc. locking manner, so that the seedling storage tray 210 is arranged in an inclined manner at a certain angle above the seedling conveying channel 110. In addition, when the number of seedling storage mechanisms 200 is multiple, the number of third mounting supports 300 and the number of seedling storage and conveying stations mentioned above are also multiple, and the number is consistent with the number of seedling storage mechanisms 200. Each seedling storage mechanism 200 is fixedly arranged by one of the third mounting supports 300, so as to be arranged in an inclined manner at a certain angle above the corresponding seedling storage and conveying station.

[0069] In some examples, as Figures 1 to 3 As shown, the automatic seedling supplementing device 1 further comprises a support rod assembly 400, which comprises two support rods 410, which are respectively arranged on two opposite sides in the width direction of the seedling conveying channel 110, and one end of the support rod 410 is movably arranged with the corresponding side of the seedling conveying channel 110 in the conveying direction of the seedling conveying channel 110, and the other end of the support rod 410 is fixedly arranged with the second end of the seedling storage tray 210. In this way, the support rod assembly 400 is arranged, and the second end of the seedling storage tray 210 is provided with auxiliary support, which cooperates with the structure of the third mounting support 300 in the previous example to further ensure that the seedling storage tray 210 can be stably arranged in an inclined manner above the seedling conveying channel 110.

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

[0071] In some examples, as Figures 1 to 3As shown, the third mounting rod body 310 is sequentially provided with a plurality of third mounting holes 320 in the third direction, and the plurality of third mounting holes 320 of the two third mounting rod bodies 310 are arranged one by one in correspondence, and the first end of the storage seedling tray 210 is obliquely mounted and fixed on the two third mounting rod bodies 310 through any pair of third mounting holes 320 of the two third mounting rod bodies 310. In this way, through the above structural arrangement, the first end of the storage seedling tray 210 can be obliquely mounted and fixed through any pair of third mounting holes 320 of the two third mounting rod bodies 310 arranged in the third direction. In addition, since the second end of the storage seedling tray 210 is assisted and supported by the 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 conveying channel 110 in the conveying direction of the seedling conveying channel 110, the inclination angle of the storage seedling tray 210 can be adaptively adjusted according to the actual seedling conveying effect requirement of the storage mechanism 200, and the specific angle adjustment range is 45°-90°. In this way, the inclination angle of the storage seedling tray 210 can better meet the various actual seedling conveying effect requirements of the storage mechanism 200.

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

[0073] In some examples, as Figures 1 to 3As shown, the automatic seedling supplementing device 1 specifically comprises a plurality of seedling storage mechanisms 200, and the automatic seedling supplementing device 1 specifically further comprises a connecting rod assembly 500, and the seedling storage trays 210 of every two adjacent seedling storage mechanisms 200 are fastened and connected through a connecting rod assembly 500, so that the seedling storage trays 210 of the plurality of seedling storage mechanisms 200 are fastened and connected together. In this way, through the above structural arrangement, the seedling storage trays 210 of the plurality of seedling storage mechanisms 200 can be well ensured to be respectively arranged at the same angle of inclination above the corresponding seedling storage and feeding stations, and since the connecting rod assembly 500 fastens and connects the plurality of 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 feeding effect requirement of the seedling storage mechanism 200, while the inclination angles of the seedling storage trays 210 of the other seedling storage mechanisms 200 can also be synchronously adjusted therewith, that is, only one supporting rod assembly 100 is needed to incline and support the second end of the seedling storage tray 210 of one of the seedling storage mechanisms 200, and the inclination angle adjustment of all the seedling storage trays 210 can be synchronously realized, so as to ensure that the inclination angles of all the seedling storage trays 210 can better meet various actual seedling feeding effect requirements of the seedling storage mechanisms 200.

[0074] It can be understood that the number of the connecting rod assemblies 500 mentioned in the present example should be specifically one less than the number of the seedling storage mechanisms 200, and each connecting rod assembly 500 should at least comprise two third connecting rod bodies 510, the two third connecting rod bodies 510 should be oppositely arranged in the width direction of the seedling feeding channel 110, and the two ends of each third connecting rod body 510 are respectively fastened and connected with the top end of the seedling storage tray 210 of one of the seedling storage mechanisms 200, so as to better ensure that the seedling storage trays 210 of all the seedling storage mechanisms 200 of the automatic seedling supplementing device 1 in the present example are connected together and can be synchronously adjusted in inclination angle.

[0075] In some examples, as Figures 1 to 4 As shown, the conveying speed of the second seedling feeding power module 220 is less than the conveying speed of the first seedling feeding power module 120. In this way, through the above structural arrangement, in the process that the second seedling feeding power module 220 conveys the seedlings on the corresponding seedling storage tray 210 to the seedling feeding channel 110, when the front ends of the seedlings contact the first seedling feeding power module 120 on the seedling feeding channel 110, since the conveying speed of the first seedling feeding power module 120 is faster, the seedlings will be pulled tight and fed forward, and will not be stacked on the lower seedling feeding channel 110 until the rear ends of the seedlings leave the second seedling feeding power module 220, and the complete seedlings are fed from the lower seedling feeding channel 110 to the planting part of the seedling planter, so as to better complete the entire automatic seedling supplementing action and ensure the seedling supplementing effect.

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

[0077] In some examples, the seedling automatic replenishing device 1 specifically further includes a trigger starting mechanism, the trigger starting mechanism is electrically connected with the seedling conveying mechanism 100 and the at least one seedling storing mechanism 200 respectively, and a switch of the trigger starting mechanism is arranged on the seedling tray of the planting part, so as to automatically start the seedling conveying mechanism 100 and the at least one seedling storing mechanism 200 when the seedlings on the seedling tray of the planting part are less than a preset number. In this way, through the signal interaction setting of the trigger starting mechanism, when the seedlings of the planting part of the rice transplanter are insufficient, the trigger signal can automatically replenish seedlings from the seedling storing and conveying mechanism 100, which greatly improves the work efficiency, reduces the labor intensity and labor cost and time cost, and also greatly promotes the development of full automation and unmanned of the rice transplanter. Through these advanced technological means, the automation, precision and intelligence of farmland operation production are realized, which brings revolutionary changes to agricultural production.

[0078] It can be understood that the trigger starting mechanism in the example can be specifically provided with the following structure, that is, a hollow position is arranged on the seedling tray of the transplanting part of the transplanter, and a limit sensor is arranged in the hollow position for material detection. The limit sensor has a certain elasticity to protrude from the hollow position to the surface of the seedling tray. When there are sufficient 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 the seedling tray has sufficient seedlings. 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 the seedlings on the seedling tray are insufficient, and the seedling feeding mechanism 100 and at least one seedling storage mechanism 200 should be started in time to automatically supplement the seedlings. For those skilled in the art, the limit sensor described above can also be replaced by a photoelectric sensor to detect the number of seedlings in the seedling tray. At this time, when there are sufficient seedlings on the seedling tray, the seedlings will come to the hollow position and block the light beam of the photoelectric sensor. At this time, it is judged that the seedling tray has sufficient seedlings. When the seedlings on the seedling tray are less than the preset number, no seedlings come to the hollow position to block the light beam of the photoelectric sensor. At this time, it is judged that the seedlings on the seedling tray are insufficient, and the seedling feeding mechanism 100 and at least one seedling storage mechanism 200 should be started in time to automatically supplement the seedlings. A weight sensor can also be used for material detection in the example. The weight sensor is arranged on the bottom side of the seedling tray to monitor the weight of the seedling tray in real time. If the weight is lower than the preset value, it indicates that the seedlings on the seedling tray are less than the preset number, that is, the seedlings on the seedling tray are insufficient, and the seedling feeding mechanism 100 and at least one seedling storage mechanism 200 should be started in time to automatically supplement the seedlings. In addition, a visual system can also be used for material detection in the 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 the preset number through image recognition technology.

[0079] The above description is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
