Description

Technical Field

[0001] This invention relates to the field of agricultural engineering technology, specifically to a rice seedling intermittent cutting and transplanting machine for rice seedlings in pots. Background Technology

[0002] There are three main methods of rice cultivation: direct seeding, transplanting, and broadcasting. While direct seeding is simple and convenient, it suffers from problems such as poor crop rotation coordination and an abundance of weeds and pests. Transplanting can address these issues to some extent, but transplanters still have drawbacks, including complex structure, high cost, limited row capacity, and low efficiency. Furthermore, the transplanting process causes significant damage to the seedbed and a long seedling recovery period.

[0003] Rice transplanting primarily involves throwing seedlings in pots. Because these potted seedlings come with their own soil, throwing them doesn't damage the roots and results in rapid recovery. However, this method requires specialized seedling trays, leading to difficulties in loading and transporting seedlings during transplanting, low production efficiency, and high labor costs. Rice potted blanket seedlings combine the advantages of rapid recovery and easy loading and transport due to their curlable shape. However, current technology for cutting and throwing rice potted blanket seedlings into pieces has low efficiency and cannot achieve continuous seedling transport and transplanting production. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a rice pot-shaped blanket seedling intermittent cutting and slicing transplanter with a compact structure and through two-stage seedling delivery linkage control and strip cutting and slicing linkage control, the accuracy of pot-shaped blanket seedling delivery, strip cutting and slicing can be ensured.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0006] A rice seedling tray cutting and transplanting machine includes a frame and a primary seedling feeding device, a strip-cutting and feeding device, and a rotary cutting device arranged sequentially on the frame along the conveying direction of the tray seedlings. The strip-cutting and feeding device includes a secondary seedling feeding device and a strip-cutting device located below it. The primary and secondary seedling feeding devices are connected by a seedling feeding power transmission mechanism to achieve coordinated seedling feeding. The primary seedling feeding device is used to transport the tray seedlings to the secondary seedling feeding device where the strip-cutting device cuts them into strips. The secondary seedling feeding device is used to transport the strips to the rotary cutting device where they are cut into block-shaped seedlings. The strip-cutting device includes a set of disc cutting blade shafts, a cutting blade motor for driving the disc cutting blade shafts to rotate, and two sets of cam lifting mechanisms located at both ends of the disc cutting blade shafts for driving their lifting and lowering. The assembly includes a horizontally arranged cutting shaft and disc cutting blades mounted side-by-side on the cutting shaft. Adjacent disc cutting blades are spaced a distance equal to the width of the strip. The rotation direction of the disc cutting blades is the same as the movement direction of the blanket-like strip. The cam lifting mechanism includes a cam and a lifting assembly driven by the cam. Both ends of the cutting shaft are connected to a lifting assembly. The cutting blade motor is mounted on the lifting assembly. The cam is mounted on the frame via a cam drive shaft. The power input end of the cam drive shaft is connected to the power output end of the rotating cutting device via a cam drive chain transmission mechanism. While the rotating cutting device performs cutting operations, its power is transmitted to the cam, causing it to rotate synchronously. The lifting assembly then drives the cutting shaft and disc cutting blades to rise and fall for strip cutting operations, achieving coordinated cutting of blocks and strips.

[0007] Furthermore, the frame includes two or more frames arranged side by side and extending along the conveying direction. The outer side of each frame, corresponding to the cutting device, has downwardly extending and parallel mounting plates. Both sets of lifting components include two sets of guide shafts, two sets of guide tubes, rollers, and a cutter shaft mounting plate. The two sets of guide shafts are vertically arranged, with both ends mounted on mounting seats of the mounting plate. The two sets of guide tubes are movably sleeved on one guide shaft. The cutter shaft mounting plate is fixedly connected to the two sets of guide tubes. Both ends of the cutter shaft pass through vertical slots in the mounting plate and are rotatably connected to the cutter shaft mounting plate. The rollers are mounted on the cutter shaft mounting plate and contact the top of the cam. The cutting motor is mounted on the cutter shaft mounting plate via a motor mounting plate. When the cam rotates, the rollers rise and fall accordingly, driving the cutter shaft mounting plate to move up and down along the guide shaft.

[0008] Furthermore, the cutter shaft mounting plate is also equipped with a cutting support plate. The cutting support plate is a horizontally placed U-shaped plate. The two side plates of the U-shaped plate are respectively connected to the cutter shaft mounting plate by connecting bolts and are located on the side close to the rotating cutting device. When the cutter shaft mounting plate moves up and down along the guide shaft, the cutting support plate moves up and down synchronously with the cutter shaft mounting plate to support and position the strips after the cutting operation, and cooperate with the rotating cutting device to perform the cutting operation.

[0009] Furthermore, the primary seedling feeding device includes a primary seedling feeding drive shaft and a primary seedling feeding driven shaft rotatably mounted at the bottom of the two frames and parallel to the cutter shaft. The primary seedling feeding drive shaft and the primary seedling feeding driven shaft are connected by a primary conveyor belt transmission assembly. Above the primary conveyor belt transmission assembly, there is also a seedling pushing plate for pushing the potted seedlings, and the seedling pushing plate is parallel to the primary seedling feeding drive shaft. The primary conveyor belt transmission assembly includes a primary seedling feeding drive wheel mounted in the middle of the primary seedling feeding drive shaft, a primary seedling feeding driven wheel mounted in the middle of the primary seedling feeding driven shaft, and a transmission connection between the primary seedling feeding drive wheel and the primary seedling feeding driven shaft. A primary seedling conveyor belt is mounted on the driven wheel of the primary seedling feeder; both ends of the primary seedling feeder drive shaft are equipped with primary seedling feeder drive sprockets, and both ends of the primary seedling feeder driven shaft are equipped with primary seedling feeder driven sprockets. The primary seedling feeder drive sprockets and primary seedling feeder driven sprockets are located inside the frame. The primary seedling feeder drive sprockets and primary seedling feeder driven sprockets on the corresponding sides are connected by a primary seedling feeder chain. Both ends of the seedling pusher plate are connected to the primary seedling feeder chain on the corresponding side and are located above the primary seedling feeder conveyor belt, moving synchronously with it. When the primary seedling feeder chain moves one section, the primary seedling feeder conveyor belt feeds seedlings forward once.

[0010] Furthermore, the secondary seedling delivery device includes a secondary seedling delivery drive shaft and a secondary seedling delivery driven shaft mounted on the mounting plate. The secondary seedling delivery drive shaft and the secondary seedling delivery driven shaft are connected by N sets of spaced secondary conveyor belt assemblies, with each space corresponding to one of the disc cutters. The secondary conveyor belt assembly includes a secondary seedling delivery drive wheel on the secondary seedling delivery drive shaft, a secondary seedling delivery driven wheel on the secondary seedling delivery driven shaft, and a secondary seedling delivery conveyor belt connected to the secondary seedling delivery drive wheel and the secondary seedling delivery driven wheel. The secondary seedling delivery drive shaft is arranged adjacent to the primary seedling delivery drive shaft. The secondary seedling delivery device also includes a tensioning shaft mounted on the mounting plate parallel to the secondary seedling delivery drive shaft. The tensioning shaft is located below the secondary seedling delivery drive shaft and the secondary seedling delivery driven shaft, causing the secondary seedling delivery conveyor belt to be tensioned outward.

[0011] Furthermore, the rotary slicing device includes an intermediate shaft parallel to the cutter shaft, a roller-type slicing mechanism coaxially mounted on the intermediate shaft, and a cutter adjustment mechanism. Both ends of the intermediate shaft are rotatably mounted on the frame via bearings, with one end connected to the slicing power transmission mechanism and the other end serving as the power output end of the rotary slicing device and connected to the cam-driven chain transmission mechanism. The roller-type slicing mechanism includes two sets of triangular side supports and three sets of slicing blade shaft assemblies. The two sets of triangular side supports are coaxially mounted at both ends of the intermediate shaft and located inside the frame. A set of the aforementioned slicing blade shaft assemblies is installed between the corresponding top ends of the two sets of triangular side supports. The three sets of slicing blade shaft assemblies are all parallel to the intermediate shaft and evenly arranged in a concentric circle around its circumference. When the intermediate shaft rotates, it drives the slicing blade shaft assemblies to rotate synchronously via the triangular side supports. Each slicing blade shaft assembly includes a hollow slicing block. The device comprises a blade mounting shaft and a cutting blade support shaft. Both ends of the cutting blade support shaft are connected to the triangular side bracket via bearings. The cutting blade mounting shaft is sleeved on the cutting blade support shaft. Linear bearings are installed between the inner ends of the cutting blade mounting shaft and the outer wall of the cutting blade support shaft, and are fixed by snap rings. A row of cutting blades, corresponding to the number of seedlings, is arranged axially on the outer side of the cutting blade mounting shaft. The cutting plane of each cutting blade is perpendicular to the cutting surface of the blanket-shaped seedling. The distance between adjacent cutting blades on the same cutting blade mounting shaft is the same as the width of the seedling. Cutting blades on adjacent cutting blade mounting shafts are staggered axially by the distance of one potted seedling. The width of the seedling is the same as the width of three potted seedlings. A cutting blade adjustment mechanism is connected to one end of the cutting blade support shaft to ensure that the cutting plane of the cutting blade remains perpendicular to the cutting surface of the blanket-shaped seedling when the intermediate shaft rotates.

[0012] Furthermore, the cutter adjustment mechanism includes an eccentric wheel, a triangular spoke plate, and a connecting rod. One side of the eccentric wheel is mounted on the frame by connecting bolts, and the other side has a protruding concentric ring that is mounted in the center hole of the triangular spoke plate through a bearing. An eccentric through hole is provided on the eccentric wheel in the concentric ring. The power input end of the intermediate shaft passes through the eccentric through hole and is rotatably connected to the frame. The center line of the eccentric wheel is parallel to and located directly below the axis of the intermediate shaft.

[0013] The triangular spokes are located between the eccentric wheel and the triangular side support. Each apex of the triangular spokes is connected to the cutting blade support shaft via the connecting rod. One end of the connecting rod has a through hole and is fixedly connected to the end of the cutting blade support shaft. The other end has a connecting rod shaft parallel to the cutting blade support shaft and is hinged to the apex of the triangular spokes. The axes of the connecting rod shaft and the cutting blade support shaft are located in the same vertical plane and are parallel to the cutting blade plane. When the cutting blade support shaft rotates around the central axis, the triangular spokes rotate synchronously around the center of the eccentric wheel, so that the cutting blade support shaft does not rotate. The cutting blade plane of the cutting blade always remains perpendicular to the cutting surface of the blanket-like seedling.

[0014] Furthermore, the rotary cutting device also includes a lateral adjustment assembly for driving the cutting blade to move laterally on the blanket-shaped seedling cutting surface. The lateral adjustment assembly includes a lateral shaft, a lateral groove, a compression spring, and a lateral trigger plate. The lateral groove is axially located on the side wall of the cutting blade support shaft away from the triangular spokes. One end of the lateral shaft is coaxially mounted in the inner cavity of the cutting blade support shaft and connected to the cutting blade mounting shaft via a connecting bolt passing through the lateral groove, forming an integral structure. The other end of the lateral shaft is located outside the cutting blade support shaft and is ball-shaped. The lateral trigger plate is vertically... The transverse trigger plate is mounted on the frame near the transverse axis and matches the movement trajectory of the cutting blade support axis. The transverse trigger plate protrudes from the middle of the inner side of the transverse axis and gradually recedes towards both ends. The compression spring is sleeved on the end of the cutting blade support axis near the triangular spoke and abuts against the cutting blade mounting axis and the triangular side bracket. When the intermediate shaft rotates to the predetermined position, the ball end of the transverse axis contacts the inner side of the transverse trigger plate and is pushed to move laterally along the transverse groove and drive the cutting blade to move laterally through the cutting blade mounting axis. The compression spring is used to reset the cutting blade mounting axis after the transverse axis leaves the transverse trigger plate.

[0015] Furthermore, the cutting blade is L-shaped, including a vertical handle and a horizontal cutting plane. The handle is vertically mounted on the cutting blade mounting shaft, and the cutting plane is located in a vertical plane parallel to the axial direction of the cutting blade mounting shaft and extends towards the end with the compression spring. The bottom and end of the horizontal section are both equipped with cutting edges. The cutting blades on each cutting blade mounting shaft are arranged in the order of cutting along the rotation direction of the central shaft, namely cutting blade No. 1, cutting blade No. 2, and cutting blade No. 3. Cutting blade No. 1 corresponds to the first potted seedling, cutting blade No. 2 corresponds to the second potted seedling in the middle of the seedling, and cutting blade No. 3 corresponds to the third potted seedling.

[0016] Furthermore, the cutting power transmission mechanism includes a cutting motor mounted on the frame, a cutting sprocket mounted on the output shaft of the cutting motor, a driven sprocket of the cutting device mounted on the power input end of the intermediate shaft, and a cutting chain that is connected to the driven sprocket of the cutting device and the cutting sprocket. The cutting chain transmits the power of the cutting motor to the driven sprocket of the cutting device, driving the intermediate shaft to rotate and realizing the rotary cutting motion of the rotary cutting knife mechanism. The cam drive chain transmission mechanism includes a cam drive sprocket, a cam drive drive sprocket, and a cam drive chain. The cam drive drive sprocket is mounted on the power output end of the intermediate shaft, and the cam drive sprocket is mounted on the power input end of the cam drive shaft. The cam drive drive sprocket transmits power to the cam drive sprocket through the cam drive chain, driving the cam to rotate and realizing the lifting and cutting motion of the disc cutting knife.

[0017] Furthermore, the seedling delivery power transmission mechanism includes a seedling delivery motor mounted on the mounting plate. The output shaft of the seedling delivery motor is parallel to and below the primary seedling delivery drive shaft. The end of the output shaft passes through the mounting plate and is equipped with a seedling delivery sprocket. The power input end of the primary seedling delivery drive shaft is equipped with a primary seedling delivery sprocket, and the power input end of the secondary seedling delivery drive shaft is equipped with a secondary seedling delivery sprocket. The seedling delivery sprocket, the primary seedling delivery sprocket, and the secondary seedling delivery sprocket are arranged in a triangle and connected by a seedling delivery drive chain, driving the secondary seedling delivery drive shaft and the primary seedling delivery drive shaft to rotate synchronously and in the same direction.

[0018] Furthermore, the frame also includes a seedling feeding plate and a cutting seedling plate located at the bottom of the frame. The frame and the seedling feeding plate and the cutting seedling plate are respectively arranged to form a blanket-shaped seedling conveying trough and a seedling conveying trough. The primary seedling feeding device is located below the blanket-shaped seedling conveying trough. The seedling feeding plate has a first installation notch for threading the primary seedling feeding conveyor belt.

[0019] The secondary seedling feeding device and the strip cutting device are located below the seedling conveying trough. The cutting seedling plate has a cutting blade slot and a second installation notch for the secondary seedling feeding conveyor belt to pass through. The cutting blade slot is located between two adjacent sets of secondary seedling feeding conveyor belts. When the disc cutter is working, it performs strip cutting through the cutting blade slot. The end of the frame is provided with a frame connecting plate. Two seedling connecting plates are installed below the seedling feeding seedling plate by connecting bolts. The two ends of the seedling connecting plates are connected to the bottom of the frame by seedling plate mounting parts. The two sides of the cutting seedling plate are connected to the bottom of the frame and are lower than the seedling feeding seedling plate.

[0020] Furthermore, the seedling pushing plate is provided in two pieces, the distance between the two seedling pushing plates is less than the length of the seedling delivery plate, the top of the seedling pushing plate is provided with serrations, and the end of the cutting seedling delivery plate near the seedling delivery plate is provided with trapezoidal teeth that cooperate with the serrations.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The rice seedling tray intermittent cutting and transplanting machine of the present invention includes a strip-cutting device comprising a set of disc cutting blades, a cutting blade motor driving its rotation, and a cam lifting mechanism driving its lifting and lowering for strip cutting. The structure is simple. The cam-driven chain transmission mechanism transmits power from the rotating cutting device to the cam in the strip-cutting device, causing it to rotate and drive the disc cutting blades to lift and lower, thus simultaneously cutting strips while rotating. This achieves coordinated operation between the strip-cutting device and the cutting device, forming an organic whole. Furthermore, the secondary seedling feeding device and the primary seedling feeding device achieve synchronized movement through the seedling feeding power transmission chain mechanism, ensuring the accuracy of seedling feeding, strip cutting, and cutting, resulting in high cutting efficiency. During seedling feeding, the disc cutting blades in the strip-cutting device can be hidden under the frame through lifting and lowering, preventing the movement of the strip-cutting device from affecting the accuracy of seedling feeding. The rotation direction of the cutting blades is the same as the movement direction of the seedlings, avoiding interference with the normal transport of the seedlings during strip cutting.

[0023] 2. The rice pot-shaped seedling intermittent cutting and throwing machine of the present invention uses a chain to connect the seedling pushing rod to achieve precise delivery of the pot seedlings during the seedling delivery operation. The length of the chain link is the length of the pot seedling. When the chain moves one link, the pot seedling moves one pot seedling position, which can achieve precise delivery of the pot seedlings.

[0024] 3. The rice seedling intermittent cutting and transplanting machine of the present invention has a cutting device that can cut the seedlings in pots into strips at set intervals. The cutting blades on the adjacent cutting blade mounting shafts are staggered by the distance of one seedling in the pot along the axial direction. The rotating cutting device rotates once in a specific order, and the cutting blades on the three sets of cutting blade mounting shafts can complete the cutting operation of three seedlings in the strip in sequence. The rotating cutting device is equipped with a lateral adjustment component, which can realize the lateral movement and reset of the cutting blades. The whole transplanting process is efficient and orderly.

[0025] 4. The rice pot-shaped seedling intermittent cutting and throwing machine of the present invention has a cutting edge at both the front end and the end end of the cutting blade that contacts the seedling in the pot, which can realize the rapid cutting of the seedling in the pot.

[0039] Detailed Implementation

[0040] The invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1-12As shown, an embodiment of the rice pot-shaped blanket seedling intermittent cutting and transplanting machine of the present invention includes a frame B and a primary seedling feeding device C, a strip-cutting and feeding device, a rotary cutting device F, and a general device G arranged sequentially on the frame B along the conveying direction of the pot-shaped blanket seedlings A. The strip-cutting and feeding device includes a secondary seedling feeding device D and a strip-cutting device E located below it. The primary seedling feeding device C and the secondary seedling feeding device D are connected by a seedling feeding power transmission chain mechanism to achieve synchronous seedling feeding. The primary seedling feeding device C is used to transport the pot-shaped blanket seedlings A to the secondary seedling feeding device D, where the strip-cutting device E cuts them into strips. The secondary seedling feeding device D is used to transport the strips to the rotary cutting device F, where they are cut into block-shaped pot seedlings. The slicing device E includes a set of disc cutting blade shafts, a cutting blade motor E6 for driving the disc cutting blade shafts to rotate, and two cam lifting mechanisms located at both ends of the disc cutting blade shafts for driving their lifting and lowering. The disc cutting blade shafts include a horizontally arranged cutting blade shaft E1 (preferably a hexagonal shaft) and disc cutting blades E2 mounted side by side on the cutting blade shaft E1. The disc cutting blades E2 are connected and fixed to the cutting blade shaft E1 through a disc cutting blade mounting part E3. There is a distance between adjacent disc cutting blades E2 that is consistent with the width of the slicing. The rotation direction of the disc cutting blades E2 is the same as the movement direction of the potted blanket-shaped seedling A. The cam lifting mechanism includes a cam E7 and a lifting assembly driven by the cam E7. Both ends of the cutter shaft E1 are connected to a lifting assembly. The cutter motor E6 is mounted on the lifting assembly. The cam E7 is mounted on the frame B via a cam drive shaft E12. The power input end of the cam drive shaft E12 is connected to the power output end of the rotating cutting device F via a cam drive chain transmission mechanism. While the rotating cutting device F performs cutting operations, its power is transmitted to the cam E7 to make it rotate synchronously. The lifting assembly then drives the cutter shaft E1 and the disc cutter E2 to rise and fall to perform strip cutting operations, realizing the linkage between cutting and strip cutting operations. This invention has a simple structure. Through the synchronous linkage of two-stage seedling feeding and the coordinated linkage of strip cutting and cutting, it forms an organic whole, ensuring the accuracy of seedling feeding, strip cutting, and cutting, and achieving high cutting efficiency. Furthermore, when the seedling feeding device is feeding seedlings, the disc cutter group in the strip cutting device can be hidden under the frame by lifting, preventing the strip cutting device from affecting the accuracy of seedling feeding operations.

[0042] In this embodiment, the general-purpose device G includes a first chain box G1, a second chain box G2, a bearing seat G3, and connecting bolts G4. The frame B has three parallel, spaced-apart frames B4 extending along the seedling conveying direction, and a seedling feeding plate B3 and a cutting seedling plate B6 located at the bottom of the frames B4. The frames B4, the seedling feeding plate B3, and the cutting seedling plate B6 form two conveying troughs. Each conveying trough includes a blanket seedling conveying trough and a strip seedling conveying trough in the conveying sequence. The primary seedling feeding device C is located below the blanket seedling conveying trough, and the secondary seedling feeding device D and the cutting device E are located below the strip seedling conveying trough. The frames B4 are fixedly connected at the bottom of the initial seedling feeding end by a horizontally arranged frame connecting plate B1. The outermost two frames B4, corresponding to the outer side of the cutting device E, are fitted with downwardly extending and parallel mounting plates C6 via connecting bolts G4. The lower ends of the two mounting plates C6 are connected as a single unit by a connecting rod. Chain box G1 and chain box G2 are respectively mounted on the frame B4 on both sides by connecting bolts G4.

The upper surface of the cutting seedling plate B6 is slightly lower than the upper surface of the seedling feeding plate B3, and a trapezoidal tooth is provided on the side near the seedling feeding plate B3. The side away from the seedling feeding plate B3 is flush with the end of the frame B4. The cutting seedling plate B6 has cutting knife slots B61 arranged side by side at intervals and extending longitudinally. The position and number of the cutting knife slots B61 correspond one-to-one with the disc cutting knife E2. When the disc cutting knife E2 is working, it performs cutting operations through the cutting knife slots B61.

[0044] In this embodiment, both sets of lifting components include two sets of guide shafts E4, two sets of guide tubes E10, rollers E8, and cutter shaft mounting plate E9. The two sets of guide shafts E4 are arranged vertically and are mounted on the mounting bases of the mounting plate C6 at both ends. The two sets of guide tubes E10 are movably sleeved on one of the guide shafts E4. The cutter shaft mounting plate E9 is fixedly connected to the two sets of guide tubes E10. The two ends of the cutter shaft E1 pass through the vertical strip holes provided on the mounting plate C6 and are connected to the cutter shaft mounting plate E9 through the bearing seat G3. The rollers E8 are mounted on the cutter shaft mounting plate E9 and contact the top of the cam E7. The cutter motor E6 is mounted on the cutter motor mounting plate E5. The cutter motor mounting plate E5 is mounted on the cutter shaft mounting plate E9 through the connecting bolts G4. The cam drive shaft E12 is connected between the two mounting plates C6 through the bearing seat G3. When the cam E7 rotates, the roller E8 rises and falls accordingly, causing the cutter shaft mounting plate E9 to move up and down along the guide shaft E4.

[0045] In this embodiment, a cutting support plate E11 is installed on the cutter shaft mounting plate E9. The cutting support plate E11 is a horizontally placed U-shaped plate. The two side plates of the U-shaped plate are respectively connected to the cutter shaft mounting plate E9 by connecting bolts G4. The bottom plate of the U-shaped plate is located on the side near the rotating cutting device F. When the cutter shaft mounting plate E9 moves up and down along the guide shaft E4, the cutting support plate E11 moves up and down synchronously with the cutter shaft mounting plate E9 to support the strips after the cutting operation and cooperate with the rotating cutting device F to perform the cutting operation.

[0046] In this embodiment, the primary seedling feeding device C includes a primary seedling feeding drive shaft C11 (preferably a hexagonal shaft) and a primary seedling feeding driven shaft C12 parallel to the cutter shaft E1. The two ends of the primary seedling feeding drive shaft C11 and the primary seedling feeding driven shaft C12 are mounted on the bottom of the two outermost frames B4 via bearing seats G3, and are connected by a primary conveyor belt transmission assembly. Above the primary conveyor belt transmission assembly, a seedling pushing plate C3 for pushing the potted seedlings is also provided, and the seedling pushing plate C3 is parallel to the primary seedling feeding drive shaft C11. In this embodiment, the seedling pushing plate C3 preferably has three sets, and the interval between two adjacent sets of seedling pushing plates C3 is suitable for the length of the blanket-shaped seedlings to be conveyed. The top of the seedling pushing plate C3 is provided with serrations, which cooperate with the trapezoidal teeth provided at one end of the seedling feeding carrier plate B3.

[0047] In this embodiment, the primary conveyor belt assembly includes a primary seedling delivery drive wheel C5 mounted in the middle of the primary seedling delivery drive shaft C11, a primary seedling delivery driven wheel C1 mounted in the middle of the primary seedling delivery driven shaft C12, and a primary seedling delivery conveyor belt C2 that is drively connected to the primary seedling delivery drive wheel C5 and the primary seedling delivery driven wheel C1. A first mounting notch is provided on the seedling delivery carrier plate B3, and the primary seedling delivery conveyor belt C2 passes through the first mounting notch, with its upper surface positioned above the seedling delivery carrier plate B3. Both ends of the primary seedling feeding drive shaft C11 are equipped with primary seedling feeding drive sprockets C13, and both ends of the primary seedling feeding driven shaft C12 are equipped with primary seedling feeding driven sprockets C14. Both primary seedling feeding drive sprockets C13 and primary seedling feeding driven sprockets C14 are located inside the frame B4. The corresponding primary seedling feeding drive sprockets C13 and primary seedling feeding driven sprockets C14 are connected via a primary seedling feeding chain C4. Both ends of the seedling pushing plate C3 are connected to the corresponding primary seedling feeding chain C4 and are positioned above the primary seedling feeding conveyor belt C2, moving synchronously with it. For every section of the primary seedling feeding chain C4 that moves, the primary seedling feeding conveyor belt C2 feeds a seedling forward once. Through the cooperation of the seedling pushing plate and the primary seedling feeding conveyor belt, precise seedling feeding is achieved.

[0048] In this embodiment, the secondary seedling feeding device D includes a secondary seedling feeding drive shaft D2 (preferably a hexagonal shaft) and a secondary seedling feeding driven shaft D6 mounted on the mounting plate C6 via a bearing seat G3. The secondary seedling feeding drive shaft D2 and the secondary seedling feeding driven shaft D6 are connected by N sets of spaced secondary conveyor belt assemblies, each spaced corresponding to a disc cutter E2. The secondary conveyor belt assembly includes a secondary seedling feeding drive wheel D3 mounted on the secondary seedling feeding drive shaft D2, a secondary seedling feeding driven wheel D7 mounted on the secondary seedling feeding driven shaft D6, and a secondary seedling feeding conveyor belt D4 connected to the secondary seedling feeding drive wheel D3 and the secondary seedling feeding driven wheel D7. A second mounting notch is also provided on the cutting seedling plate B6, through which the secondary seedling feeding conveyor belt D4 passes. The cutting blade slot B61 is located between two adjacent sets of secondary seedling feeding conveyor belts D4, and the disc cutter E2 performs cutting operations through the cutting blade slot B61 during operation.

[0049] In this embodiment, the secondary seedling feeding drive shaft D2 is arranged adjacent to the primary seedling feeding drive shaft C11 and is connected by a seedling feeding power transmission chain mechanism. The seedling feeding power transmission chain mechanism includes a seedling feeding motor C7 (preferably a servo motor) mounted on the mounting plate C6 via connecting bolts G4. The output shaft of the seedling feeding motor C7 is parallel to and below the primary seedling feeding drive shaft C11. The end of the output shaft passes through the mounting plate C6 and is equipped with a seedling feeding sprocket C8. The power input end of the primary seedling feeding drive shaft C11 is equipped with a primary seedling feeding sprocket C10, and the power input end of the secondary seedling feeding drive shaft D2 is equipped with a secondary seedling feeding sprocket D1. The seedling feeding sprockets C8, C10, and D1 are all arranged in a triangle on the outside of the frame B4 away from the cutting blade motor E6 and are connected by a seedling feeding drive chain C9. The seedling feeding drive chain C9 drives the secondary seedling feeding drive shaft D2 and the primary seedling feeding drive shaft C11 to rotate synchronously and in the same direction. The two-stage conveying method, consisting of seedling mat conveying and seedling strip conveying, ensures a smooth connection between the two seedling trays and makes the seedling strip conveying smoother and more precise.

[0050] In this embodiment, the secondary seedling feeding device D also includes a tensioning shaft D5 parallel to the secondary seedling feeding drive shaft D2. The tensioning shaft D5 is mounted on the mounting plate C6 through the bearing seat G3 and is located below the secondary seedling feeding drive shaft D2 and the secondary seedling feeding driven shaft D6 to tension the secondary seedling feeding conveyor belt D4 outward.

[0051] In this embodiment, the rotary slicing device F includes an intermediate shaft F1 parallel to the cutter shaft E1, a roller-type slicing mechanism coaxially mounted on the intermediate shaft F1, and a cutter adjustment mechanism. Both ends of the intermediate shaft F1 are rotatably mounted on the frame B4 via bearings, with one end connected to the slicing power transmission mechanism and the other end serving as the power output end of the rotary slicing device F and connected to the cam-driven chain transmission mechanism. The roller-type slicing mechanism includes two sets of triangular side supports F5 (preferably three-pronged spoke supports) and three sets of slicing blade shaft assemblies. The two sets of triangular side supports F5 are coaxially mounted at both ends of the intermediate shaft F1 and located inside the frame B4. A slicing blade shaft assembly is installed between the corresponding top ends of the two sets of triangular side supports F5. All three sets of slicing blade shaft assemblies are parallel to the intermediate shaft F1 and are evenly arranged in a concentric circle around its circumference. Adjacent sets of slicing blade shaft assemblies are spaced 120 degrees apart in the circumferential direction. When the intermediate shaft F1 rotates, it drives the cutting blade shaft assembly to rotate synchronously through the triangular side bracket F5, thereby realizing the cutting of the strips into pieces by the roller-type cutting mechanism.

[0052] In this embodiment, the cutting power transmission mechanism includes a cutting motor F18 mounted on a frame B4 via connecting bolts G4, a cutting sprocket F17 mounted on the output shaft of the cutting motor F18, a driven sprocket F2 mounted on the power input end of the intermediate shaft F1, and a cutting chain F16 that is driveably connected to the driven sprocket F2 and the cutting sprocket F17. The cutting chain F16 transmits the power of the cutting motor F18 to the driven sprocket F2, driving the intermediate shaft F1 to rotate, thereby realizing the rotary cutting motion of the rotary cutting knife mechanism. The power output end of the intermediate shaft F1 is driveably connected to the cam-driven chain transmission mechanism to transmit power. The cutting power transmission mechanism is located inside the first chain box G1.

[0053] In this embodiment, the cam-driven chain transmission mechanism includes a cam-driven sprocket E13, a cam-driven drive sprocket F12, and a cam-driven chain E14. The cam-driven drive sprocket F12 is mounted on the power output end of the intermediate shaft F1, and the cam-driven sprocket E13 is mounted on the power input end of the cam-driven shaft E12. The cam-driven drive sprocket F12 transmits power to the cam-driven sprocket E13 through the cam-driven chain E14, causing the cam E7 to rotate and realizing the lifting and cutting motion of the disc cutter E2. The cam-driven chain transmission mechanism is located inside the second chain box G2.

[0054] In this embodiment, the cutting blade shaft assembly includes a hollow cutting blade mounting shaft F8 and a cutting blade support shaft F15. Both ends of the cutting blade support shaft F15 are mounted on a triangular side bracket F5 via bearings. The cutting blade mounting shaft F8 is sleeved on the cutting blade support shaft F15. Linear bearings F14 are installed between the inner ends of the cutting blade mounting shaft F8 and the outer wall of the cutting blade support shaft F15, and are fixed by snap rings F13. A row of cutting blades F9, corresponding to the number of seedlings, is arranged axially on the outer side of the cutting blade mounting shaft F8. The cutting plane of the cutting blades F9 is perpendicular to the cutting surface of the blanket-like seedlings (i.e., the plane where the blanket-like seedlings of the rice pot are located). The distance between adjacent cutting blades F9 on the same cutting blade mounting shaft F8 is consistent with the width of the seedling. Adjacent cutting blades F9 on adjacent cutting blade mounting shafts F8 are staggered axially by the distance of one potted seedling. In this embodiment, the width of the seedling is preferably the width of three potted seedlings, i.e., cutting is performed every three seedlings.

[0055] In this embodiment, the cutter adjustment mechanism is connected to one end of the cutter support shaft F15 to ensure that the cutting plane of the cutter F9 is always perpendicular to the cutting surface of the blanket-shaped seedling when the intermediate shaft F1 rotates. The cutter adjustment mechanism includes an eccentric wheel F3, a triangular spoke F4 (preferably an equilateral triangular spoke), and a connecting rod F6. One side of the eccentric wheel F3 is mounted on the frame B4 by a connecting bolt G4, and the other side has a protruding concentric ring, which is mounted in the center hole of the triangular spoke F4 through a bearing. An eccentric through hole is provided on the eccentric wheel F3 in the concentric ring. The power input end of the intermediate shaft F1 passes through the eccentric through hole and is rotatably connected to the frame B4. The center line of the eccentric wheel F3 is parallel to and located directly below the axis of the intermediate shaft F1. The triangular spoke F4 is located between the eccentric wheel F3 and the triangular side support F5. Each apex of the triangular spoke F4 is connected to the cutting blade support shaft F15 via a connecting rod F6. One end of the connecting rod F6 has a through hole and is fixedly connected to the end of the cutting blade support shaft F15. The other end has a connecting shaft parallel to the cutting blade support shaft F15. The connecting shaft is hinged to the hinge hole at the apex of the triangular spoke F4. The axis of the connecting shaft and the axis of the cutting blade support shaft F15 are in the same vertical plane and parallel to the cutting plane. When the cutting blade support shaft F15 rotates around the intermediate shaft F1, the connecting rod F6 drives the triangular spoke F4 to rotate synchronously around the center of the eccentric wheel F3, so that the cutting blade support shaft F15 does not rotate on its own, and the cutting plane of the cutting blade F9 always remains perpendicular to the cutting surface of the carpet-like seedling.

[0056] In this embodiment, the rotary cutting device F further includes a lateral adjustment assembly for driving the cutting blade F9 to move laterally on the blanket-shaped seedling cutting surface. The lateral adjustment assembly includes a lateral shaft F10, a lateral groove F151, a compression spring F7, and a lateral trigger plate F11. The lateral groove F151 is axially disposed on the side wall of the cutting blade support shaft F15 away from the triangular spoke F4. One end of the lateral shaft F10 is coaxially mounted in the inner cavity of the cutting blade support shaft F15 and connected to the cutting blade mounting shaft F8 as an integral structure through a connecting bolt G4 passing through the lateral groove F151. The other end of the lateral shaft F10 is located outside the cutting blade support shaft F15 and is ball-shaped. The lateral trigger plate F11 is vertically mounted near the lateral shaft. The frame B4 at end F10 matches the movement trajectory of the cutting blade support shaft F15. The transverse trigger plate F11 protrudes from the middle of the inner side of the transverse shaft F10 and gradually recedes towards both ends. The compression spring F7 is sleeved on one end of the cutting blade support shaft F15 near the triangular spoke F4 and abuts against the cutting blade mounting shaft F8 and the triangular side bracket F5. When the intermediate shaft F1 rotates to the predetermined cutting position, the ball end of the transverse shaft F10 contacts the inner side of the transverse trigger plate F11 and is pushed to move laterally along the transverse groove F151. Through the cutting blade mounting shaft F8, the cutting blade F9 moves laterally to achieve cutting. The compression spring F7 is used to reset the cutting blade mounting shaft F8 after the transverse shaft F10 leaves the transverse trigger plate F11. The lateral adjustment component allows the cutting blade to be inserted between two seedlings and into the inside of the seedling. While the cutting blade is cutting downwards perpendicular to the cutting surface, it is driven to move laterally to the back of the inside of the seedling, and then cuts the blanket-like seedling in the pot, cutting it into independent units. The lateral adjustment function of the lateral adjustment component can prevent the cutting blade from damaging the seedling and improve the quality of transplanting.

[0057] In this embodiment, the cutting blade F9 is L-shaped, including a vertical handle and a horizontal straight cutting blade. The handle is vertically mounted on the cutting blade mounting shaft F8. The straight cutting blade is located in a vertical plane parallel to the axial direction of the cutting blade mounting shaft F8 and extends towards the end where the compression spring F7 is located. Both the bottom and end of the straight cutting blade have cutting edges. The cutting blades F9 on each cutting blade mounting shaft F8 are arranged in the order of cutting along the rotation direction of the intermediate shaft F1, namely cutting blade F91, cutting blade F92, and cutting blade F93. Cutting blade F93 corresponds to the third potted seedling of the stalk, cutting blade F92 corresponds to the second potted seedling in the middle of the stalk, and cutting blade F91 corresponds to the first potted seedling. After the stalk is cut into pieces, it is pushed into the subsequent seedling guiding and throwing process by the vertical handle of the cutting blade F9 during the lateral movement.

[0058] Working principle:

[0059] 1) Precision delivery principle

[0060] The seedling delivery motor C7 is preferably a servo motor, which can accurately output rotational power according to the control signal to ensure the accuracy of seedling delivery. The seedling delivery motor C7 transmits power to the secondary seedling delivery drive shaft D2 and the primary seedling delivery drive shaft C11 through the seedling delivery drive chain C9, so that the secondary seedling delivery drive shaft D2 and the primary seedling delivery drive shaft C11 move synchronously. The secondary seedling delivery drive shaft D2 transmits power to the secondary seedling delivery driven shaft D6 through the secondary seedling delivery conveyor belt D4 to realize the delivery of the seedlings after cutting.

[0061] The primary seedling feeding drive shaft C11 transmits power to the primary seedling feeding driven shaft C1 via the primary seedling feeding conveyor belt C2. A primary seedling feeding drive sprocket C13 is installed on the primary seedling feeding drive shaft C11, and a primary seedling feeding driven sprocket C14 is installed on the primary seedling feeding driven shaft C11. A primary seedling feeding chain C4 connects the primary seedling feeding drive sprocket C13 and the primary seedling feeding driven sprocket C14. A seedling pusher plate C3 is installed between the two sets of primary seedling feeding chains C4. The seedling pusher plate C3 moves in coordination with the primary seedling feeding conveyor belt C2. One movement of the primary seedling feeding chain C4 completes one seedling feeding operation, ensuring the accuracy of the seedling feeding operation.

[0062] 2) Principle of strip cutting motion

[0063] The cutting blade motor E6 is directly connected to the cutting blade shaft E1 to achieve the rotation of the cutting blade E2. The cutting blade shaft E1 is connected to the lifting component of the cam lifting mechanism to achieve the lifting of the cutting blade E2. Through the rotation and lifting of the cutting blade E2, the potted seedlings are cut into strips every three plants.

[0064] 3) Principle of cutting motion

[0065] The cutting motor F18 drives the intermediate shaft F1 of the cutting device to rotate. The intermediate shaft F1 then drives the triangular bracket F5 to rotate, which in turn drives the cutting blade mounting shaft F8 to rotate, thereby moving the first cutting blade F91, the second cutting blade F92, and the third cutting blade F93. During the cutting operation, following the rotation direction of the intermediate shaft F1 and the cutting sequence, the first cutting blade F91 first cuts off the already cut seedlings, completing the cutting of the first seedling. Then, the second cutting blade F92 moves, completing the cutting of the second seedling, and finally, the third cutting blade F93 moves, completing the cutting of the third seedling. Figure 10As shown, the first cutting blade F91, the second cutting blade F92, and the third cutting blade F93 form a group of three. One set of cutting blade shafts can assemble multiple sets of cutting blades. The assembly order of the cutting blades from right to left is: first cutting blade F91, second cutting blade F92, and third cutting blade F93. The disc cutting blade E2 first cuts the right side of the pot mat of the first potted seedling. The handle of the first cutting blade F91 cuts the pot mat connecting the first and second potted seedlings. The straight cutting blade of the first cutting blade F91 cuts the rear side of the pot mat of the first potted seedling. After the first cutting blade F91 completes the cutting, all the pot mats connected to the first potted seedling are cut, and the first potted seedling is cut into an independent unit that can be transplanted. The first cutting blade, F91, cuts the soil layer connecting the first and second seedlings. Therefore, the second cutting blade, F92, cuts the soil layer connecting the second and third seedlings, as well as the soil layer behind the second seedling. The second seedling is thus cut into an independent unit ready for transplanting. Since every three seedlings form a group, when the third cutting blade, F93, cuts, the soil layer connecting the third and second seedlings has already been cut by the second cutting blade, F92, and the third seedling has already been cut from the first seedling in the next group by the disc cutting blade, E2. Therefore, when the third cutting blade, F93, cuts, its straight blade cuts the soil layer behind the third seedling, thus cutting the third seedling into an independent unit ready for transplanting. The combined operation of the L-shaped cutting blade F9 and the disc cutting blade E2, along with the sequential cutting operation of the L-shaped cutting blade F9, enables the L-shaped cutting blade F9, which only has cutting edges on both sides, to achieve three-sided cutting, thereby realizing the cutting of the potted, mat-like seedlings into pieces.

[0066] 4) Principle of coordinated cutting of blocks and strips

[0067] When the cutting motor F18 drives the intermediate shaft F1 of the cutting device to rotate, the cam drive drive sprocket F12 drives the cam drive shaft E12 to move through the cam drive chain E14. The cam E7 installed on the cam drive shaft E12 lifts the cutter shaft E1 with a gap, and the disc cutter E2 performs the cutting operation. At the same time, the cutting support plate E11 rises and cooperates with the cutting blade F9 to complete the cutting action. After completing one cutting operation cycle, the cam E7 disengages from the roller E8, the cutter shaft E1 returns to its original position, the disc cutter E2 descends and hides under the cutting strip carrier plate B6, and the first-stage seedling feeding device C performs the next round of seedling feeding operation.

[0068] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
