[0031] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying 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.

[0033] It should be noted that all the directionality 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, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directionality indications also change accordingly.

[0034] 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 defined as "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 to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0035] In one embodiment, as Figures 1 to 4As shown, the embodiment of the present application also provides an automatic seedling supplementing device 1, which specifically can include a seedling feeding mechanism 100 and a seedling storing mechanism 200. The seedling feeding mechanism 100 specifically can 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 storing mechanism 200 specifically can include a seedling storing tray 210, a rolling seedling feeding structure 220 and a shielding member 260. The seedling storing tray 210 is obliquely arranged above the seedling feeding channel 110, and the rolling seedling feeding structure 220 is at least partially rotationally arranged on the seedling storing tray 210. The shielding member 260 is arranged on one side of the rolling seedling feeding structure 220 adjacent to the seedling feeding channel 110, so as to prevent the seedlings on the seedling feeding channel 110 from being rolled up when the rolling seedling feeding structure 220 rotates.

[0036] It can be understood that the automatic seedling supplementing device 1 of the embodiment of the present application can be specifically applied to the automatic seedling supplementing operation of a seedling planting machine, that is, when the seedling planting part of the seedling planting machine has insufficient seedlings (specifically less than a preset number), the seedlings stored in the automatic seedling supplementing device 1 are automatically fed into the seedling planting part of the seedling planting machine. Therefore, the automatic seedling supplementing device 1 of the embodiment of the present application can be designed alone to be directly mounted on the seedling planting machine on the market for use, or can be directly used as a mechanism of the seedling planting machine and added to any type of existing seedling planting machine to form a new seedling planting machine for use. The above-mentioned rolling seedling feeding structure 220 is mainly used for preventing the seedlings on the seedling storing tray 210 from falling when the rolling seedling feeding structure 220 is stationary, and providing sufficient traction for the seedlings on the seedling storing tray 210 when the rolling seedling feeding structure 220 rotates, so as to drive the seedlings on the seedling storing tray 210 to be conveyed to the seedling feeding channel 110. Among them, the above-mentioned rolling seedling feeding structure 220 preventing the seedlings on the seedling storing tray 210 from falling when the rolling seedling feeding structure 220 is stationary specifically refers to that when the rolling seedling feeding structure 220 is not started to work, that is, when the rolling seedling feeding structure 220 is not rotated, the rolling seedling feeding structure 220 can prevent the seedlings on the seedling storing tray 210 from falling by the blocking formed by the structure (such as the hook tooth 222) of the rolling seedling feeding structure 220, that is, preventing the seedlings on the seedling storing tray 210 from falling to the seedling feeding channel 110 due to the gravity after reaching the bottom end of the corresponding seedling storing tray 210 and then falling under the action of gravity.

[0037] In addition, the above-mentioned seedling storing tray 210 obliquely arranged above the corresponding seedling feeding channel 110 can be as follows Figure 1The 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.

[0038] In this way, the automatic seedling supplementing device 1 provided by the embodiment of the present application can make the seedlings stored on each seedling storage tray 210 of the seedling storage mechanism 200 sequentially come to the bottom end of the corresponding seedling storage tray 210 under the action of gravity. When the automatic seedling supplementing device is started, the seedlings at the bottom end of the seedling storage tray 210 can be automatically conveyed to the seedling conveying path 110 of the seedling conveying mechanism 100 under the rotation of the rolling seedling conveying structure 220, and then automatically conveyed to the planting part of the seedling planting machine under the conveying of the first seedling conveying power module 120 of the seedling conveying mechanism 100, thereby automatically completing the seedling supplementing operation on the planting part of the seedling planting machine. The entire seedling supplementing process does not involve excessive manual participation except for starting the device, and can greatly improve the work efficiency of the seedling planting machine by greatly improving the seedling supplementing efficiency of the planting part of the seedling planting machine. At the same time, due to the arrangement of the shielding member 260, the seedlings at the bottom end of the seedling storage tray 210 can be automatically conveyed to the seedling conveying path 110 of the seedling conveying mechanism 100 under the rotation of the rolling seedling conveying structure 220, thereby effectively preventing the rolling seedling conveying structure 220 from damaging the seedlings on the seedling conveying path 110, such as rolling up the seedlings on the seedling conveying path 110, to ensure the seedling supplementing effect of the automatic seedling supplementing device 1.

[0039] In some examples, as Figure 1 , Figure 3 and Figure 4As shown, the rolling seedling feeding structure 220 can specifically include a rolling rod body 221, a plurality of hook teeth 222, and a second seedling feeding power module 223. The rolling rod body 221 is rotationally arranged at the bottom end of the seedling storage tray 210. The plurality of hook teeth 222 are uniformly arranged on the circumferential side of the rolling rod body 221. The second seedling feeding power module 223 is fixedly arranged at the bottom end of the seedling storage tray 210 and is drivingly connected with the rolling rod body 221 to drive the rolling rod body 221 to rotate. In this way, through the above structural arrangement, when the second seedling feeding power module 223 is not working, the rolling rod body 221 is not rotating, i.e., it is static, the seedlings on the seedling storage tray 210 can be prevented from falling by the blocking of the plurality of hook teeth 222. When the second seedling feeding power module 223 is working, i.e., the rolling rod body 221 is rotating, the plurality of hook teeth 222 can provide sufficient traction to the seedlings on the seedling storage tray 210 (specifically, the bottom end thereof) to drive the seedlings on the seedling storage tray 210 to be conveyed to the seedling feeding channel 110. Further, the rolling rod body 221 can be a cylindrical structure and is arranged to extend along a first direction, which is the width direction of the seedling storage tray 210. In this way, when the rolling rod body 221 rotates, the seedlings at the bottom end of the seedling storage tray can be maximally automatically conveyed to the seedling feeding channel 110. Further, the plurality of hook teeth 222 are arranged in multiple rows along the first direction and are equally spaced on the circumferential side of the rolling rod body 221. In this way, through the above structural arrangement, when the seedlings stored on the seedling storage tray 210 come to the bottom end of the corresponding seedling storage tray 210 under the action of gravity, on the one hand, when the rolling rod body 221 is static, the seedlings can be prevented from falling to the seedling feeding channel 110 under the action of gravity by the blocking of at least one row of hook teeth 222; on the other hand, when the rolling rod body 221 is rotating, sufficient traction provided by at least one row of hook teeth 222 to the seedlings on the seedling storage tray 210 can effectively drive the seedlings on the seedling storage tray 210 to be conveyed to the seedling feeding channel 110.

[0040] It can be understood that the bottom end of the seedling storage tray 210 mentioned in the present example specifically refers to one end of the seedling storage tray 210 adjacent to the seedling feeding channel 110. Similarly, 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 second seedling feeding power module 223 mentioned in the present example can specifically be a motor power structure and can be arranged on the seedling storage tray 210, so that the rolling rod body 221 can be driven to rotate by a servo motor drive on the seedling storage tray 210 in cooperation with the transmission of a transmission wheel and a transmission belt. To enable the seedlings on the seedling storage tray 210 (specifically, the bottom end thereof) to be conveyed to the seedling feeding channel 110 under the rotation of the rolling rod body 221, the second seedling feeding power module 223 can specifically drive the rolling rod body 221 to rotate along the first direction. Figure 2In addition, the hook tooth 222 in the present example can be a cone or a pyramid, so that the seedlings on the seedling storage tray 210 can be well blocked when the rolling seedling conveying structure 220 is static, and the seedlings on the seedling storage tray 210 can be provided with sufficient traction when the rolling seedling conveying structure 220 rotates. Further, the end of the hook tooth 222 is hook-shaped, so that the traction on the seedlings on the seedling storage tray 210 can be further increased when the rolling seedling conveying structure 220 rotates. In addition, the height of the hook tooth 222 protruding from the rolling rod body 221 in the present example is 5% to 20% of the diameter of the rolling rod body 220, so that the hook tooth 222 has high strength, and the seedlings on the seedling storage tray 210 can be well blocked when the rolling seedling conveying structure 220 is static, and the seedlings on the seedling storage tray 210 can be provided with sufficient traction when the rolling seedling conveying structure 220 rotates.

[0041] In some examples, as shown in Figure 1 、 Figure 3 and Figure 4 , the side of the seedling storage tray 110 in contact with the seedlings is the seedling storage side (i.e., the groove bottom surface of the seedling storage groove body 211 mentioned below), and the rolling rod body 221 protrudes from the seedling storage side. In this way, the protruding part of the rolling rod body 221 can prevent the seedlings on the seedling storage tray 210 from falling when the rolling seedling conveying structure 220 is static, and better drive the seedlings on the seedling storage tray 210 to the seedling conveying path 110 when the rolling seedling conveying structure 220 rotates. Further, at least half of the rolling rod body 221 protrudes from the seedling storage side, so that the effect of preventing the seedlings on the seedling storage tray 210 from falling when the rolling seedling conveying structure 220 is static and the effect of conveying the seedlings when the rolling seedling conveying structure 220 rotates can be better ensured.

[0042] In some examples, as shown in Figure 1 、 Figure 3 and Figure 4 , the seedling conveying path 110 is provided with a seedling outlet 111 at the end along the conveying direction, and the seedling outlet 111 is used to connect to the planting part (not shown) of the rice transplanter. In this way, the first seedling conveying power module can better automatically convey the seedlings on the seedling conveying path 110 to the planting part of the rice transplanter through the above structure.

[0043] It can be understood that, in order to facilitate the out-seed port 111 to be more smoothly connected with the planting part of the rice transplanter, the out-seed port 111 can be specifically inclined, and at this time, the end of the seed conveying path 110 along the conveying direction in the example is provided with the out-seed port 111, which specifically means that the end of the seed conveying path 110 along the conveying direction is provided with a guide slope, and the outlet of the guide slope (i.e., the out-seed port 111) is located above the planting part of the rice transplanter, so that when the seedlings are conveyed to the end of the seed conveying path 110 by the first seed conveying power module 120, the seedlings are smoothly conveyed to the planting part of the rice transplanter through the smooth guidance of the guide slope.

[0044] In some examples, as shown in Figure 1 , Figure 3 and Figure 4 , the seed conveying path 110 is sequentially provided with at least one seed storage and conveying station (not shown) along the conveying direction, and the seed storage tray 210 is inclinedly arranged above a seed storage and conveying station. In this way, through the structural arrangement of the seed storage and conveying station, the installation and positioning of the seed storage tray 210 on the seed conveying path 110 can be better achieved. Further, the automatic seed supplementing device 1 can specifically include a plurality of seed storage mechanisms 200, and the plurality of seed storage mechanisms 200 are arranged at intervals. In this way, through the arrangement of the plurality of seed storage mechanisms 200, the number of seedlings stored by the seed storage mechanism 200 of the automatic seed supplementing device 1 at the same time can be effectively improved, so as to improve the automatic seed supplementing efficiency of the automatic seed supplementing device 1. Further, the inclination angles of the seed storage trays 210 of the plurality of seed storage mechanisms 200 relative to the seed conveying path 110 are the same. In this way, through the above structural arrangement, it can be ensured that the seed conveying rate of each seed storage mechanism 200 to the seed conveying path 110 is consistent, so as to ensure the automatic seed supplementing effect of the automatic seed supplementing device 1.

[0045] It can be understood that, the number of seed storage and conveying stations in the example should be consistent with the number of seed storage mechanisms 200, that is, one seed storage mechanism 200 is arranged above each seed storage and conveying station.

[0046] In some examples, as shown in Figure 1 , Figure 3 and Figure 4As shown, the shielding member 260 can be specifically a semi-arc cover which is arranged in a spaced manner at the side of the rolling rod body 221 adjacent to the seedling conveying path 110, and the arc of the semi-arc cover is matched with the outer contour of the rolling rod body 221. In this way, the semi-arc cover can be matched with the rolling rod body 221 of the cylindrical structure, so as to form an effective physical isolation between the side of the rolling rod body 221 adjacent to the seedling conveying path 110 and the seedling conveying path 110, thereby effectively preventing the rolling seedling conveying structure 220 from damaging the seedlings on the seedling conveying path 110, such as rolling up the seedlings on the seedling conveying path 110, so as to ensure the seedling supplementing effect of the automatic seedling supplementing device 1. Further, the semi-arc cover is arranged in a rotating manner at the bottom end of the seedling storage tray 210, and the rotating axis of the semi-arc cover is the same as the rotating axis of the rolling rod body 221. In this way, the semi-arc cover can be rotated relative to the rolling rod body 221, so as to adjust the shielding position of the semi-arc cover, so that even if the inclination angle of the seedling storage tray 210 needs to be adjusted to adapt to seedlings of different weights, after the inclination angle of the seedling storage tray 210 is adjusted, the semi-arc cover can be rotated and adjusted, so as to ensure that the semi-arc cover is always kept between the side of the rolling rod body 221 adjacent to the seedling conveying path 110 and the seedling conveying path 110, so as to achieve the shielding while not hindering the rolling rod body 221 from conveying the seedlings downward. Further, the bottom end of the seedling storage tray 210 is further provided with a movable locking structure (not shown) for locking the semi-arc cover at any rotating position. In this way, the movable locking structure can ensure that the semi-arc cover can be locked by the movable locking structure after each rotating adjustment, so as to ensure that it will not be unnecessarily deviated in position during use, so as to avoid affecting the shielding effect or causing the rolling rod body 221 to convey the seedlings downward.

[0047] It can be understood that the half-arc cover mentioned in the example is arranged on the side of the rolling rod body 221 adjacent to the seedling conveying channel 110 and spaced from the side of the rolling rod body 221 adjacent to the seedling conveying channel 110 by a predetermined distance, so as not to affect the normal rotation of the rolling rod body 221. For those skilled in the art, the mounting and fixing mode of the half-arc cover can be various, in addition to the rotation setting mentioned above, including but not limited to screw fixing, buckle fixing, etc., as long as the half-arc cover is arranged between the side of the rolling rod body 221 adjacent to the seedling conveying channel 110 and the seedling conveying channel 110. In addition, the shielding member 260 can also be not limited to the half-arc cover in the example, but can also be a structure such as a baffle arranged on the side of the rolling rod body 221 adjacent to the seedling conveying channel 110, as long as the structure can form effective physical isolation between the side of the rolling rod body 221 adjacent to the seedling conveying channel 110 and the seedling conveying channel 110. Therefore, in some examples, the shielding member 260 can be a shielding plate arranged between the rolling seedling conveying structure 220 and the seedling conveying channel 110 to prevent the rolling seedling conveying structure 220 from damaging the seedlings on the seedling conveying channel when rotating.

[0048] In some examples, as shown in Figure 1 , Figure 3 and Figure 4 , one side of the seedling storage tray 210 is recessed with a seedling storage groove 211, which is mainly used for storing seedlings. The seedling storage mechanism 200 further includes a seedling pressing frame 230, which is movably arranged on the groove side of the seedling storage groove 211 in the second direction, for limiting the seedlings in the seedling storage groove 211 in the second direction. The second direction is perpendicular to the groove bottom surface of the seedling storage groove 211. In this way, the structure of the seedling pressing frame 230 can effectively prevent the seedlings stored in the seedling storage groove 211 from falling down through the groove side of the seedling storage groove 211 due to the inclination of the seedling storage tray 210 under the action of gravity.

[0049] It can be understood that the groove wall of the storage groove body 211 corresponding to the bottom end of the storage tray 210 in the example is provided in a hollow manner to leave an outlet, so that the seedlings stored in the storage groove body 211 can be driven by the rolling seedling conveying structure 220 to come out of the outlet and be conveyed to the seedling conveying channel 110. The pressure seedling frame 230 mentioned in the example is movably arranged at the groove side of the storage groove body 211 in the second direction, which means that the pressure seedling frame 230 is movably arranged at the groove side of the storage groove body 211 in the second direction, and the distance between the pressure seedling frame 230 and the groove bottom surface of the 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 that the storage groove body 211 needs to store, so as to meet the user's demand for storing different numbers of seedlings in the storage groove body 211.

[0050] In some examples, as shown in Figure 1 , Figure 3 and Figure 4 , the storage mechanism 200 further includes a first mounting bracket 240 and a second mounting bracket 250, which are arranged at intervals in the length direction of the storage groove body 211. The first mounting bracket 240 includes two first mounting rod bodies 241, which are respectively fixedly arranged at two opposite sides in the width direction of the storage groove body 211. Each first mounting rod body 241 is 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 pressure seedling 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 includes two second mounting rod bodies 251, which are respectively arranged at two opposite sides in the width direction of the storage groove body 211, and each second mounting rod body is movably arranged in the second direction with the corresponding side of the storage groove body 211. The other end of the pressure seedling frame 230 is installed and fixed on the two second mounting rod bodies 251. In this way, the pressure seedling frame 230 can be movably arranged at the groove side of the storage groove body 211 in the second direction through the above structure. At the same time, since the two ends of the pressure seedling frame 230 are movably connected to the storage groove body 211 in the second direction through different movable structures, the user can make different movable adjustments to the two ends of the pressure seedling frame 230 in the second direction when storing different numbers of seedlings in the storage groove body 211, so as to better meet the limiting requirements of the corresponding seedlings in the storage groove body 211.

[0051] It can be understood that each first mounting rod body 241 in the example should be arranged to extend in the second direction, so as to better sequentially open a plurality of first mounting holes 242 in the second direction. At the same time, since the first mounting bracket 240 is mainly arranged at the top end of the seedling storage tray 210, and the seedlings are mainly stored in the corresponding seedling storage groove body 211 from this end, for the activity adjustment of one end of the seedling pressing frame 230 in the second direction, flexibility and convenience should be mainly considered, therefore, the plurality of first mounting holes 242 can each adopt a side opening hole structure, and a side locking rod 243 is arranged to rotate, so that the side opening of the plurality of first mounting holes 242 on the same side is switched back and forth between opening and closing through clockwise or counterclockwise rotation of the side locking rod 243. In this way, one end of the seedling pressing frame 230 can be quickly clamped in any pair of first mounting holes 242 of the two first mounting rod bodies 241, and then quickly installed and fixed through the side locking rod 243. In addition, the activity arrangement of each second mounting rod and the corresponding side of the seedling storage groove body 211 in the second direction in the example can be achieved through the following structure. Each second mounting rod is also arranged to extend in the second direction, and a second mounting hole 252 is formed in each second mounting rod. The second mounting hole 252 is a long hole structure, which is specifically arranged to extend in the second direction. In this way, the corresponding second mounting rod can be installed and fixed on the corresponding side of the seedling storage groove body 211 at any position in the second direction through the second mounting hole 252, so as to better achieve the activity arrangement of the corresponding second mounting rod and the corresponding side of the seedling storage groove body 211 in the second direction.

[0052] In some examples, as shown in FIG. 13, Figure 1 The seedling pressing frame 230 can specifically include a first connecting rod body 231, a second connecting rod body 232, and a plurality of seedling pressing rod bodies 233. One end of each seedling pressing rod body 233 is bent to form a first bent portion, and the other end of each seedling pressing rod body 233 is bent to form a second bent portion. The first connecting rod body 231 connects the first bent portions of the plurality of seedling pressing rod bodies 233 together, and the two ends of the first connecting rod body 231 are installed and fixed through any pair of first mounting holes 242 of the two first mounting rod bodies 241. The second connecting rod body 232 connects the second bent portions of the plurality of seedling pressing rod bodies 233 together, and the two ends of the second connecting rod body 232 are installed and fixed on the two second mounting rod bodies 251. In this way, the above structure can ensure that the seedling pressing frame 230 in the example can better press and limit the seedlings in the seedling storage groove body 211 in the second direction, while making the overall structure more simple and compact.

[0053] It can be understood that the plurality of seedling pressing rods 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 rods 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 rods 234, at least one height adjusting rod 234 is movably arranged between the first bending portions of the plurality of seedling pressing rods 233, and at least one height adjusting rod 234 is movably arranged between the second bending portions of the plurality of seedling pressing rods 233. Thus, when the seedling pressing frame 230 is movably arranged at the groove side of the seedling storage groove body 211, the height of each height adjusting rod 234 (i.e. the vertical distance between it and the groove surface of the seedling storage groove body 211) can be adjusted, 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 seedling storage groove body 211, to achieve the purpose of being able to hold the leaf part of the seedlings without hindering the smooth sliding of the seedlings due to the height being too low.

[0054] In some examples, as shown in Figure 3 , Figure 4 and Figures 1 to 4 , the groove bottom surface of the seedling storage groove body 211 can be specifically provided with a plurality of ribs 212, each rib 212 extending along the length direction of the seedling storage groove body 211. In this way, the structure of the plurality of ribs 212 can be used instead of the contact between the groove bottom surface of the seedling storage groove body 211 and the seedlings in the seedling storage groove body 211, so as to greatly reduce the contact area therebetween, effectively reducing the frictional resistance of the seedlings sliding in the seedling storage groove body 211, and thereby facilitating the seedlings to be quickly lowered to the bottom end of the seedling storage tray 210 when the rolling seedling feeding structure 220 rotates.

[0055] In some examples, as shown in Figure 1 and Figure 3 , the automatic seedling replenishing device 1 specifically further includes a third mounting bracket 300, each third mounting bracket 300 includes two third mounting rod bodies 310, the two third mounting rod bodies 310 are respectively fixedly arranged on two opposite sides in the width direction of the seedling feeding channel 110, and the first end of the seedling storage tray 210 is respectively fixedly arranged on the two third mounting rod bodies 310. In this way, the third mounting bracket 300 can be well arranged on the third mounting bracket 300.

[0056] It can be understood that the first end of the seedling storage tray 210 mentioned in the example specifically refers to the end of the seedling storage tray 210 adjacent to the seedling conveying channel 110, that is, 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 and obliquely mounted and fixed on two third mounting rod bodies 310, which specifically means that the two opposite sides of the first end in the width direction of the seedling storage tray 210 are respectively and obliquely mounted and fixed on the corresponding third mounting rod body 310. The mounting and fixing mode can be a locking mode such as screw, buckle or welding, so that the seedling storage tray 210 is obliquely arranged at a certain angle above the seedling conveying channel 110. In addition, when the number of the seedling storage mechanism 200 is multiple, the number of the third mounting bracket 300 and the number of the seedling storage and conveying station mentioned above are also multiple, and the number is consistent with the number of the seedling storage mechanism 200. Each seedling storage mechanism 200 is mounted and fixed by one of the third mounting brackets 300, so as to be obliquely arranged at a certain angle above the corresponding seedling storage and conveying station.

[0057] In some examples, as shown in Figure 4 The automatic seedling supplementing device 1 specifically further includes a support rod assembly 400, and the support rod assembly 400 includes two support rod bodies 410. The two support rod bodies 410 are respectively arranged on the two opposite sides in the width direction of the seedling conveying channel 110, and one end of the support rod body 410 is movably arranged with the corresponding side of the seedling conveying channel 110 in the conveying direction of the seedling conveying channel 110. The other end of the support rod body 410 is mounted and fixed with the second end of the seedling storage tray 210. In this way, by providing auxiliary support for the second end of the seedling storage tray 210 through the structure of the support rod assembly 400, and cooperating with the structure of the third mounting bracket 300 in the previous example, the oblique arrangement of the seedling storage tray 210 above the seedling conveying channel 110 can be further stabilized.

[0058] It can be understood that the second end of the seedling storage tray 210 mentioned in the example specifically refers to the end of the seedling storage tray 210 away from the seedling conveying channel 110, that is, the top end of the seedling storage tray 210 mentioned above.

[0059] In some examples, as shown in Figure 2As 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.

[0060] In some examples, as Figure 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.

[0061] In some examples, as Figures 1 to 3As shown, the automatic seedling supplementing device 1 specifically comprises a plurality of seedling storing mechanisms 200, and the automatic seedling supplementing device 1 specifically further comprises a plurality of connecting rod assemblies 500. Two adjacent seedling storing mechanisms 200 are fastened and connected through a connecting rod assembly 500, so that the seedling storing trays 210 of the plurality of seedling storing mechanisms 200 are fastened and connected together. In this way, through the above structural arrangement, the seedling storing trays 210 of the plurality of seedling storing mechanisms 200 can be well ensured to be respectively arranged at the same angle of inclination above the corresponding seedling storing and feeding stations, and at the same time, due to the fastening and connection of the plurality of seedling storing mechanisms 200 by the connecting rod assemblies 500, the inclination angle of the seedling storing tray 210 of one of the seedling storing mechanisms 200 can be adaptively adjusted according to the actual seedling feeding effect requirement of the seedling storing mechanism 200, while the inclination angles of the seedling storing trays 210 of the other seedling storing mechanisms 200 can also be synchronously adjusted, that is, only one supporting rod assembly 100 is needed to incline and support the second end of the seedling storing tray 210 of one of the seedling storing mechanisms 200, and the inclination angle adjustment of all the seedling storing trays 210 can be synchronously realized to ensure that the inclination angles of all the seedling storing trays 210 can better meet the various actual seedling feeding effect requirements of the seedling storing mechanisms 200.

[0062] 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 storing mechanisms 200, and each connecting rod assembly 500 should at least comprise two third connecting rod bodies 510, which are 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 storing tray 210 of one of the seedling storing mechanisms 200 to better ensure that the seedling storing trays 210 of all the seedling storing mechanisms 200 of the automatic seedling supplementing device 1 in the present example are connected together and can be synchronously adjusted in inclination angle.

[0063] In some examples, as shown, Figures 1 to 3 Figures 1 to 3 Figures 1 to 3 Figures 1 to 4 The conveying speed of the rolling seedling feeding structure 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 rolling seedling feeding structure 220 conveys the seedlings on the corresponding seedling storing 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, 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 rolling seedling feeding structure 220, and the complete seedlings are fed from the lower seedling feeding channel 110 to the planting part of the seedling planter to better complete the entire automatic seedling supplementing action and ensure the seedling supplementing effect.

[0064] It can be understood that the first seedling conveying power module 120 in the example can specifically include a seedling conveying belt 121 and a motor power structure for driving the seedling conveying belt 121 to convey. The motor power structure is driven by a servo motor, cooperates with the transmission of a transmission wheel and a transmission belt, and drives the seedling conveying belt 121 to move in a cycle, so that the seedling conveying belt 121 conveys through the cycle to drive the seedlings to convey 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 means that the front end of the seedlings contacts the seedling conveying belt 121 on the seedling conveying channel 110. In addition, the surface of the seedling conveying belt 121 can also be provided with a plurality of hooks (not shown in the figure), and the plurality of hooks are arranged in an array on the surface of the seedling conveying belt 121. In this way, when the first seedling conveying power module 120 works, the seedlings on the seedling conveying channel 110 can be provided with sufficient traction by the plurality of hooks when the seedling conveying belt 121 rotates, to drive the seedlings on the seedling conveying channel 110 to convey to the planting part of the rice transplanter. In addition, based on the foregoing description, the rolling seedling conveying structure 220 drives the seedlings on the seedling storage tray 210 to convey to the horizontal seedling conveying channel by rotating, so the conveying speed of the rolling seedling conveying structure 220 in the example can also be the rotating speed of the rolling seedling conveying structure 220.

[0065] In some examples, the automatic seedling supplementing device 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 storage 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 storage 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 supplement the seedlings from the seedling storage and conveying mechanism 100, which greatly improves the work efficiency, reduces the labor intensity, labor cost and time cost, and promotes the development of full automation and unmanned of the rice transplanter.

[0066] 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.

[0067] The above description is only the preferred embodiment of the present application, and does not limit the patent scope of the present application.
