Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to a fully automatic rice transplanting device and method. Background Technology

[0002] Currently, rice transplanters are widely used in the rice transplanting field, eliminating the need for manual transplanting and greatly facilitating farmers. However, current rice transplanters can only automatically transplant rice seedlings; it is still necessary to manually feed the seedling trays to the input port of the transplanter. In other words, when transplanting rice seedlings, it is still necessary for a person to stand on the transplanter's vehicle and feed the seedlings into the transplanter, which is inconvenient to use. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a fully automatic rice transplanting device, comprising:

[0004] The vehicle body and the rice transplanter located on the vehicle body, wherein a pre-storage frame is fixedly installed on the vehicle body, the pre-storage frame includes a feeding layer and several pre-storage layers, and a first drive mechanism drives several of the pre-storage layers to run synchronously.

[0005] A lifting mechanism that can move up and down, the lifting mechanism including a horizontally movable support rod;

[0006] The feeding mechanism and the horizontally movable translation mechanism are provided. The feeding mechanism corresponds to the input port of the rice transplanter, and the translation mechanism is located below the feeding mechanism and overlaps with the movement path of the lifting mechanism.

[0007] Preferably, the feeding layer and the pre-storage layer have the same structure, each including at least two shafts, rollers and belts. The two shafts are rotatable but fixed in position and are respectively inserted into both sides of the pre-storage frame. Several rollers are fixedly sleeved on the two shafts. Two rollers in the same vertical plane are a pair. The two rollers in the same pair are connected by belt drive. The seedling tray is placed on the belt.

[0008] Preferably, the first drive mechanism includes a plurality of first gears, a first chain and a first motor. Two first gears are fixedly sleeved on each shaft of the pre-storage layer. Two adjacent shafts are connected to each other by a first chain meshing with the two first gears. The output shaft of the first motor is connected to one of the shafts.

[0009] Preferably, the lifting mechanism includes a fixed-position third motor, two rotating rods, a connecting frame, a vertical guide rail, a horizontal guide rail, and a fourth motor. The output shaft of the third motor is drivenly connected to one rotating rod, and the two rotating rods are drivenly connected through two first transmission mechanisms. The horizontal guide rail is drivenly connected to the first transmission mechanism. The fourth motor is fixed in position, and the output shaft of the fourth motor is drivenly connected to a second transmission mechanism. The connecting frame is drivenly connected to the second transmission mechanism.

[0010] Preferably, the lifting mechanism further includes two vertical guide rails and several vertical wheels. The two vertical guide rails are fixed in position and are parallel to the first transmission mechanism. The several vertical wheels are fixedly connected to the connecting frame and clamp the vertical guide rails from the front and back.

[0011] Preferably, the translation mechanism includes a fixed frame, a movable frame, a load-bearing rod, and a second gear. The movable frame is movably connected to the fixed frame. Several load-bearing rods are fixedly installed on the movable frame. The load-bearing rods are lower than the highest height that the support rod can reach. A rack groove is provided on the inner top wall of the movable frame. A motor is fixedly installed on the fixed frame. The second gear is fixedly sleeved on the output shaft of the motor and meshes with the rack groove.

[0012] Preferably, the feeding mechanism is located above the translation mechanism. The feeding mechanism includes a mounting frame, a directional guide rail, a push plate, a directional pulley, and a third transmission mechanism. The push plate is movably connected to the mounting frame. A sixth motor is fixedly mounted on the mounting frame. The third transmission mechanism is drivenly connected to the output shaft of the sixth motor and to the push plate.

[0013] Preferably, it also includes a conveyor belt, one end of which is fixedly equipped with a hook, and the side of the pre-storage rack is fixedly equipped with a buckle corresponding to the hook.

[0014] Preferably, it also includes a receiving mechanism located below the feed inlet of the rice transplanter. The receiving mechanism includes a top plate, a limiting protrusion, a bottom plate, a seventh motor, and a fourth transmission mechanism. The top plate has a strip groove on its top.

[0016] Pre-storage of seedling trays: The lifting mechanism moves the seedling trays on the feeding layer to the pre-storage layer. Each pre-storage layer is placed once. After completion, all pre-storage layers rotate synchronously, causing the seedling trays on them to move one space away from the lifting mechanism. This process is repeated until the pre-storage layer is full of seedling trays.

[0017] Seedling tray transport: The lifting mechanism moves one of the seedling trays on the pre-storage layer to a position higher than the translation mechanism. The load-bearing rod moves to a position below the seedling tray. The lifting mechanism lowers and places the seedling tray on the load-bearing rod. The load-bearing rod moves the seedling tray to a position below the feeding mechanism. The feeding mechanism pushes the seedling tray out and slides it to the input port of the rice transplanter. This process continues until the outermost row on the upper layer is transported. After completion, all pre-storage layers rotate synchronously, causing the seedling trays on them to move one grid closer to the lifting mechanism. This process is repeated in sequence.

[0018] The distance between each grid should not be less than the length of the seedling tray.

[0019] The present invention has the following beneficial effects:

[0020] The seedling trays can be pre-stored and automatically transported from the pre-stored area to the input port of the rice transplanter, replacing manual labor. During transplanting, there is no need for manual labor to stand on the transplanter's vehicle and move with it, achieving fully automatic transplanting, which is more convenient to use and saves manpower.

[0034] The principles and features of the present invention are described below. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0035] It should be noted that when a part or component is considered to be "connected to," "located on," or "assembled" to another part or component, it can be directly mounted on the other part or component, or it may be located in an intermediate part or component. The terms "left," "right," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0036] In one specific implementation, such as Figure 1-11 As shown, a fully automatic rice transplanter includes:

[0037] The vehicle body 1 and the rice transplanter 6 located on the vehicle body 1, wherein a pre-storage frame 2 is fixedly installed on the vehicle body 1, the pre-storage frame 2 includes a feeding layer 22 and a plurality of pre-storage layers 21, and a first drive mechanism 23 drives the plurality of pre-storage layers 21 to run synchronously.

[0038] A lifting mechanism 3 that can move up and down, the lifting mechanism 3 including a horizontally movable support rod 31;

[0039] The feeding mechanism 5 and the horizontally movable translation mechanism 4 are provided. The feeding mechanism 5 corresponds to the input port of the rice transplanter 6, and the translation mechanism 4 is located below the feeding mechanism 5 and overlaps with the movement path of the lifting mechanism 3.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the feeding layer 22 and the pre-storage layer 21 have the same structure, each including at least two shafts 201, rollers 202 and belts 203. The two shafts 201 are rotatable but fixed in position and are respectively inserted into both sides of the pre-storage frame 2. Several rollers 202 are fixedly sleeved on the two shafts 201. Two rollers 202 in the same vertical plane are a pair. The two rollers 202 in the same pair are connected by a belt 203. The seedling tray is placed on the belt 203.

[0041] like Figure 4 As shown, in this embodiment, the first drive mechanism 23 includes a plurality of first gears 231, a first chain 232, and a first motor 233. Two first gears 231 are fixedly sleeved on the shaft 201 of each pre-storage layer 21 on the same side. Two adjacent shafts 201 are connected to each other by meshing with the two first gears 231 through a first chain 232. The output shaft of the first motor 233 is connected to one of the shafts 201, so that the first motor 233 drives one shaft 201 to rotate while simultaneously driving the other shafts 201 to rotate synchronously through the first chain 232 and the first gear 231, thereby realizing the synchronous movement of the multi-layer pre-storage layers 21.

[0042] The second motor 24 is connected to one of the shafts 201 in the feeding layer 21. When the second motor 24 starts, it drives the belt 203 in the feeding layer 21 to rotate.

[0043] like Figure 1 , Figure 5 and Figure 6As shown, the lifting mechanism 3 includes a fixed-position third motor 32, two rotating rods 33, a connecting frame 35, a vertical guide rail 36, a horizontal guide rail 38, and a fourth motor 311. The output shaft of the third motor 32 is connected to one of the rotating rods 33. The two rotating rods 33 are located in the same vertical plane and on one side of the pre-storage frame 2. The two rotating rods 33 are connected by two first transmission mechanisms 34. Each first transmission mechanism 34 consists of two gears and a chain. The two gears are fixedly sleeved on the two rotating rods 33, and the chain meshes with the two gears to achieve transmission. The transverse guide rail 38 is connected to the first transmission mechanism 34. When the third motor 32 starts, the first transmission mechanism 34 drives the transverse guide rail 38 to rise and fall. At least two transverse wheels 39 that can move within the transverse guide rail 38 are fixedly installed on both sides of the connecting frame 35. The transverse wheels 39 are adapted to the transverse guide rail 38 to lift the connecting frame 35 and fix its posture. Several parallel support rods 31 are fixedly installed on the connecting frame 35. The several support rods 31 are located on the same plane to support the seedling tray. The fourth motor 311 is fixedly installed on the connecting frame 35. The output shaft of the fourth motor 311 is connected to the second transmission mechanism 312. The second transmission mechanism 312 has the same structure as the first transmission mechanism 34. The connecting frame 35 is connected to the second transmission mechanism 312. When the fourth motor 311 starts, the second transmission mechanism 312 drives the connecting frame 35 to translate, thereby moving the support rods 31 horizontally into the pre-storage rack 2. The lifting mechanism 3 also includes two vertical guide rails 36 and several vertical wheels 37. The two vertical guide rails 36 are fixed in position and are parallel to the first transmission mechanism 34. The several vertical wheels 37 are fixedly connected to the connecting frame 35 and clamp the vertical guide rails 36 from front to back, so that the trajectory of the connecting frame 35 during lifting is stable and the length direction of the vertical guide rails 36 does not sway.

[0044] like Figure 1 , Figure 5 and Figure 7As shown, in this embodiment, the translation mechanism 4 and the lifting mechanism 3 are arranged opposite to each other. The translation mechanism 4 includes a fixed frame 41, limiting wheels 42, a movable frame 43, load-bearing rods 44, and a second gear 46. The fixed frame 41 is fixed in position. Multiple limiting wheels 42 are fixedly installed on the upper and lower sides of the fixed frame 41. The movable frame 43 is located between the upper and lower limiting wheels 42 and is movably connected to the fixed frame 41 through the limiting wheels 42. Specifically, the outer side of the limiting wheels 42 is concave, and the upper and lower sides of the movable frame 43 are convex to match the concave shape, allowing the movable frame 43 to move laterally. Several load-bearing rods 44 are fixedly installed on the movable frame 43, and the load-bearing rods 44 are lower than the maximum height that the support rod 31 can reach. The inner top wall of the movable frame 43 is provided with a rack groove 45, and a motor is fixedly installed on the fixed frame 41. The second gear 46 is fixedly sleeved on the output shaft of the motor. The second gear 46 meshes with the rack groove 45, so that the movable frame 43 is driven to move when the motor rotates.

[0045] like Figure 8 As shown, in this embodiment, the feeding mechanism 5 is located above the translation mechanism 4. The feeding mechanism 5 includes a mounting frame 51, a directional guide rail 52, a push plate 53, directional pulleys 54, a sixth motor 55, an inclined plate 56, and a third transmission mechanism 57. The mounting frame 51 is fixed in position, and two directional guide rails 52 are fixedly installed at the bottom of the mounting frame 51. Directional pulleys 54 adapted to the directional guide rails 52 are fixedly installed on both sides of the push plate 53, meaning the push plate 53 is hung on the directional guide rails 52 and is movable. The sixth motor 55 is fixedly installed on the mounting frame 51. The third transmission mechanism 57 has the same structure as the first transmission mechanism 34. One gear of the third transmission mechanism 57 is connected to the output shaft of the sixth motor 55, and the chain of the third transmission mechanism 57 is fixedly connected to the push plate 53. That is, when the sixth motor 55 starts, the third transmission mechanism 57 drives the push plate 53 to move along the length direction of the directional guide rail 52. The inclined plate 56 is fixed in position, with its bottom located at the input port of the rice transplanter 6 and its top located on the side of the translation mechanism 4 and lower than the load-bearing rod 44. The push plate 53, the inclined plate 56, and the input port of the rice transplanter 6 are located on the same vertical plane. The distance between the bottom of the push plate 53 and the top of the load-bearing rod 44 is greater than zero and less than the height of the seedling tray, to ensure that the push plate 53 can push the seedling tray from the load-bearing rod 44 onto the inclined plate 56.

[0046] like Figure 1 and Figure 9As shown, in this embodiment, a conveyor belt 7 is also included. A hook 72 is fixedly installed at one end of the conveyor belt 7, and a buckle 71 corresponding to the hook 72 is fixedly installed on the side of the pre-storage rack 2. When feeding, the conveyor belt 7 is hung on the buckle 71 by the hook 72. The conveyor belt 7 corresponds to the feeding layer 22, so that when feeding, the seedling tray only needs to be placed on the conveyor belt 7 and the conveyor belt 7 can be started to transport the seedling tray to the feeding layer 22. After feeding is completed, the conveyor belt 7 can be easily removed from the pre-storage rack 2.

[0047] like Figure 2 , Figure 10 and Figure 11 As shown, in this embodiment, a receiving mechanism 8 is also included, located below the feeding port of the rice transplanter 6 and mounted on the vehicle body 1. The receiving mechanism 8 includes a top plate 81, a limiting protrusion 83, a linear guide rail 84, a bottom plate 85, linear pulleys 86, a seventh motor 87, and a fourth transmission mechanism 88. A strip groove 82 is provided on the top of the top plate 81. Linear guide rails 84 are fixedly installed on both sides of the bottom of the top plate 81. Linear pulleys 86 corresponding to the linear guide rails 84 are fixedly installed on both sides of the bottom plate 85. The bottom plate 85 is located at the bottom of the top plate 81. A limiting protrusion 83 passing through the strip groove 82 is fixedly installed on the top of the bottom plate 85. The limiting protrusion 83 protrudes from the top surface of the top plate 81. The seventh motor 87 is fixed in position. The fourth transmission mechanism 88 has the same structure as the first transmission mechanism 34. One gear of the fourth transmission mechanism 88 is connected to the output shaft of the seventh motor 87, and the other gear is also fixed in position. The chain of the fourth transmission mechanism 88 is fixedly connected to the base plate 85. That is, when the seventh motor 87 starts, it drives the base plate 85 to move left and right through the fourth transmission mechanism 88. The top plate 81 is located on the side of the feeding layer 22. After the rice transplanter 6 has finished transplanting the seedlings from the seedling tray, the empty tray falls onto the top plate 81. When the limiting protrusion 83 moves, it pushes the empty tray to move onto the base plate 85, which protrudes from the outside of the strip groove 82. After the base plate 85 retracts, the empty tray is held by the side of the top plate 81, causing the empty tray to fall back onto the feeding layer 22.

[0048] Furthermore, it also includes a collection container, which is detachably fixed to the side of the pre-storage rack 2, i.e. the installation position of the conveyor belt 7, by means of a buckle 71. When the seedlings are being thrown, the feeding layer 22 can be reversed to move the empty discs on the feeding layer 22 to the collection container. When feeding again, the collection container can be removed and the conveyor belt 7 can be installed without affecting the use.

[0049] Furthermore, there are two pre-storage racks 2, located on both sides of the rice transplanter 6. There are also two lifting mechanisms 3, corresponding to the number of pre-storage racks 2, allowing for the storage of more seedling trays. The width of each pre-storage rack 2 is greater than the sum of the widths of two seedling trays, enabling two seedling trays to be placed side-by-side on each layer. Each lifting mechanism 3 has at least four support rods 31, with each pair corresponding to one seedling tray. There are at least eight load-bearing rods 44, with the left half of the load-bearing rods 44 corresponding to the left-side lifting mechanism 3, and the right half corresponding to the right-side lifting mechanism 3. When one load-bearing rod 44 moves to the feeding position below the feeding mechanism 5 to discharge material, the other load-bearing rod 44 moves to the corresponding receiving position, repeating this crisscrossing process. This allows the rice transplanter 6 to continuously discharge seedlings, improving discharge efficiency. The load-bearing rod 44 and the support rod 31 are installed in a staggered manner, that is, when the load-bearing rod 44 moves onto the path of the lifting mechanism 3, the support rod 31 can pass through the gap between the load-bearing rods 44.

[0050] A fully automatic rice seedling throwing method: including a fully automatic rice seedling throwing device as described above;

[0051] Pre-storage of seedling trays: The lifting mechanism 3 moves the seedling trays on the feeding layer 22 to the pre-storage layer 21. Each pre-storage layer 21 is placed once. After completion, all pre-storage layers 21 rotate synchronously, causing the seedling trays on them to move one grid away from the lifting mechanism 3. This process is repeated until the pre-storage layer 21 is full of seedling trays.

[0052] Seedling tray transport: The lifting mechanism 3 moves the seedling tray on one of the pre-storage layers 21 to a position higher than the translation mechanism 4. The load-bearing rod 44 moves to a position below the seedling tray. The lifting mechanism 3 lowers and places the seedling tray on the load-bearing rod 44. The load-bearing rod 44 moves the seedling tray to a position below the feeding mechanism 5. The feeding mechanism 5 pushes the seedling tray out and slides it to the input port of the rice transplanter 6. This process continues until the outermost row on the feeding layer 22 is transported. After this is completed, all pre-storage layers 21 rotate synchronously, causing the seedling trays on them to move one grid closer to the lifting mechanism 3. This process is repeated in sequence.

[0053] The distance between each grid should not be less than the length of the seedling tray.

[0054] During the seedling tray pre-storage stage: The seedling tray is placed on the feeding layer 22. The second motor 24 is started to move the seedling tray closer to the lifting mechanism 3. The third motor 32 is started to lower the support rod 31 to the same height as the feeding layer 22. Then, the fourth motor 311 is started to move the support rod 31 below the seedling tray. The third motor 32 rotates in the opposite direction to raise the support rod 31 and lift the seedling tray. Then, the fourth motor 311 rotates in the opposite direction to reset the support rod 31. The support rod 31 continues to rise until it corresponds to one of the pre-storage layers 21, that is, the support rod 31 is slightly higher (within the height range of the bottom protrusion of the seedling tray) than one of the pre-storage layers 21. After moving, the support rod 31 lowers to place the seedling tray on the pre-storage layer 21, and the support rod 31 resets. This process is repeated to fill all the pre-storage layers 21 in one row. That is, in one cycle, each pre-storage layer 21 is filled only once. After the cycle is completed, the first motor 233 is started to drive all the pre-stored layers 21 to move synchronously in the same direction, moving one row of seedling trays one position away from the lifting mechanism 3, making room for the seedling trays to be placed in the next cycle, and repeating this process until all the pre-stored layers 21 are filled.

[0055] During the seedling tray transport stage: the third motor 32 is started to move the support rod 31 to be level with one of the pre-storage layers 21, then the support rod 31 is moved to the bottom of the seedling tray, the support rod 31 is raised to lift the seedling tray, the support rod 31 is reset, then the support rod 31 is raised above the load-bearing rod 44, the motor is started to move the load-bearing rod 44 to the bottom of the support rod 31, the support rod 31 is controlled to descend and pass between the load-bearing rods 44, so that the seedling tray moves onto the load-bearing rod 44, the load-bearing rod 44 is controlled to move to the bottom of the feeding mechanism 5, the sixth motor 55 is started to drive the push plate 53 to move and push the seedling tray onto the inclined plate 56, and finally it moves into the input port of the seedling thrower 6. Repeat this process until the row of seedling trays closest to the lifting mechanism 3 on the pre-storage layer 21 is completely removed. That is, in one cycle, each pre-storage layer 21 is only removed once. After removal, the first motor 233 is started to rotate in the opposite direction, so that the seedling trays on the pre-storage layer 21 move one unit closer to the lifting mechanism 3, so that the seedling trays are replenished at the removal position, and another cycle begins.

[0056] Furthermore, if there are two pre-storage racks 2, then there are two sets of load-bearing rods 44. During the seedling tray transportation stage, the seedling trays in the two pre-storage racks 2 are transported alternately. That is, when the right load-bearing rod 44 moves to the bottom of the feeding mechanism 5 to unload the material, the left load-bearing rod 44 is located below the support rod 31 to load the material. At the same time, the right support rod 31 takes the material from the pre-storage layer 21. After the material is unloaded, the right load-bearing rod 44 moves to the bottom of the right support rod 31, and the left load-bearing rod 44 moves to the bottom of the feeding mechanism 5 to unload the material. This process is repeated alternately.

[0057] Furthermore, if each pre-storage layer 21 stores two seedling trays side by side, then two seedling trays will be transported at a time during the seedling tray transportation stage, and the seedlings will be fed in sequence during the feeding process.

[0058] Furthermore, after the rice seedling thrower 6 throws out the seedling trays, the empty trays fall onto the top plate 81. The seventh motor 87 is started, causing the limit protrusion 83 to move and push the empty trays onto the feeding layer 22. The feeding layer 22 rotates in the opposite direction to move the empty trays into the collection container for collection, making it convenient for recycling and sorting.

[0059] In summary, the seedling trays can be pre-stored and automatically transported from the pre-stored location to the input port of the seedling transplanter 6, replacing manual labor. During transplanting, there is no need for manual labor to stand on the vehicle of the seedling transplanter 6 and move with it, achieving fully automatic transplanting, which is more convenient to use and saves manpower.

2. A fully automatic rice transplanting method, characterized in that: Includes the fully automatic rice transplanting device described in claim 1; Seedling tray pre-storage: The lifting mechanism (3) moves the seedling trays on the feeding layer (22) to the pre-storage layer (21). Each pre-storage layer (21) performs a placement action once. After completion, all pre-storage layers (21) rotate synchronously, causing the seedling trays on them to move one grid away from the lifting mechanism (3). This process is repeated until the pre-storage layer (21) is full of seedling trays. Seedling tray transport: The lifting mechanism (3) moves the seedling tray on one of the pre-storage layers (21) to a position higher than the translation mechanism (4), the load-bearing rod (44) moves to a position below the seedling tray, the lifting mechanism (3) lowers and places the seedling tray on the load-bearing rod (44), the load-bearing rod (44) moves the seedling tray to a position below the feeding mechanism (5), the feeding mechanism (5) pushes the seedling tray out and slides it to the input port of the seedling thrower (6) until the outermost row on the upper layer (22) is transported. After completion, all pre-storage layers (21) rotate synchronously, causing the seedling trays on them to move one grid closer to the lifting mechanism (3), and repeating in sequence. The distance between each grid should not be less than the length of the seedling tray.
