Description

Technical Field

[0001] This invention belongs to the field of pruning device technology, and particularly relates to a stem and leaf pruning device for plug seedlings.

[0002] Seedling cultivation is an important link in the flower production industry chain. The quality of seedlings directly affects the yield and quality of the product. In recent years, the mechanized plug tray seedling cultivation technology has emerged, breaking free from the constraints of natural conditions and regional limitations, realizing the factory production and commercial supply of seedlings, and becoming a symbol of the transition from traditional agriculture to modern agriculture. Plug tray seedling cultivation technology uses lightweight soilless substrate materials such as peat moss and vermiculite as seedling substrates, and uses mechanized precision sowing, one seed per hole, and one seedling per planting, which is a modern seedling cultivation technology.

[0003] When cultivating seedlings in plug trays, the top of the seedlings needs to be pruned to remove apical dominance in order to encourage the growth of more lateral branches.

[0004] The existing pruning method involves manually removing the top of the seedlings with scissors or chainsaws. However, this method is labor-intensive, and the pruner's arms will feel sore after long-term work, which can cause significant damage to the arms in the long run. In addition, the pruning process requires manual placement of the seedling trays to be pruned, which greatly reduces the pruning speed and efficiency.

[0005] Therefore, in view of the above situation, there is an urgent need to provide a stem and leaf pruning device for plug seedlings to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of the invention is to provide a stem and leaf pruning device for plug seedlings, which effectively solves the problems of high labor intensity, long-term damage to arms, and low pruning efficiency caused by the need to manually place the plug seedlings during pruning.

[0007] This invention proposes a stem and leaf pruning device for plug seedlings, including a pruning table. A mounting frame is fixedly connected to one side of the top surface of the pruning table. A guide rail is fixedly connected to the outer wall of the mounting frame. A slide seat is slidably disposed on the surface of the guide rail. An electric chainsaw is fixedly connected to the outer wall of the slide seat and is disposed above the pruning table. Two symmetrically arranged L-shaped conveyor platforms are fixedly connected to the outer walls of both sides of the pruning table. A transfer frame is slidably disposed on the L-shaped conveyor platform. A transfer component is disposed on the transfer frame. A conveying frame is fixedly connected to the top surface of the L-shaped conveyor platform. The transfer frame and the conveying frame are disposed opposite to each other. A fixing component is disposed inside the conveying frame. A conveying component is disposed on the L-shaped conveyor platform. The fixing component and the conveying component are disposed on both sides of the pruning table.

[0008] The system is equipped with a pruning table, mounting frame, guide rail, slide block, electric chainsaw, L-shaped conveyor table, transfer frame, transfer assembly, transport frame, fixing assembly, and conveying assembly. The position of the slide block on the guide rail is pre-adjusted according to the height of the seedlings in the plug trays. The height of the electric chainsaw is then changed, and the chainsaw is activated. In conjunction with the adjustment of the transfer assembly, fixing assembly, and conveying assembly, the plug trays are transferred, fixed, and transported for pruning. During transport, the seedlings come into contact with the electric chainsaw, which trims the top of the seedlings. This automated transfer and pruning operation saves time and effort, significantly reducing the workload of operators.

[0009] Furthermore, the transfer frame is U-shaped, with multiple equidistant partitions fixedly connected to the inner walls of both sides. The transfer assembly includes a support frame, which is fixedly connected to one end of the bottom surface of the L-shaped conveyor table. A drive motor is fixedly connected to the outer wall of the support frame. The power output shaft of the drive motor is connected to a threaded screw via a coupling. A lifting seat is threadedly connected to the surface of the threaded screw. A guide rod is fixedly connected to one end of the top surface of the L-shaped conveyor table, and the lifting seat is slidably disposed on the surface of the guide rod. A hydraulic cylinder is fixedly connected to one end of the outer wall of the lifting seat away from the guide rod. Fixed plates are fixedly connected to both outer walls of the transfer frame. The output end of the hydraulic cylinder is fixedly connected to the outer wall of one fixed plate. A guide hole is provided on the outer wall of the other fixed plate on the transfer frame. A guide rod is fixedly connected to one end of the outer wall of the lifting seat away from the guide rod. The fixed plate is slidably disposed on the surface of the fixed plate through the guide hole. The hydraulic cylinder and the guide rod are symmetrically distributed at both ends of the transfer frame.

[0010] By setting up a transfer component and extending and adjusting the hydraulic cylinder, the first acupoint is moved into the interior of the fixed component. The drive motor is started and the hydraulic cylinder is retracted to return the transfer frame to the initial position above. The drive motor is then reversed to lower the transfer frame back to the side of the acupoint, completing the transfer of one acupoint. The subsequent acupoints are then moved forward a certain distance in sequence. This cycle can be repeated to achieve the transfer of multiple acupoints.

[0011] Furthermore, the fixing assembly includes a movable groove, which is opened inside the conveying frame. A hydraulic cylinder two is fixedly connected to the inner wall of the movable groove, and a clamping slide is fixedly connected to the output end of the hydraulic cylinder two. Two spaced guide blocks are fixedly connected to the inner wall of the bottom surface of the conveying frame. The clamping slide is slidably disposed in the movable groove between the two guide blocks. Two symmetrically arranged triangular wedges are fixedly connected to the outer walls on both sides of the clamping slide. Two side clamps are rotatably disposed inside the conveying frame with respect to the clamping slide. A turning hole is opened in the middle of the side clamps. Two balance rotating rods are fixedly connected to the bottom surface of the conveying frame. The side clamps are rotatably disposed on the surface of the balance rotating rods through the turning holes. A spring one is fixedly connected to the outer wall of the side clamp away from the clamping slide. The end of the spring one away from the side clamp is fixedly connected to the inner wall of the side of the conveying frame. A fixing hole is opened inside the bottom surface of the conveying frame, and a fixing rod is fixedly connected inside the fixing hole. A connecting frame is fixedly connected to the end of the fixing rod away from the conveying frame. The connecting frame is slidably disposed on the top surface of the L-shaped conveyor table.

[0012] By setting a fixed component and adjusting the second hydraulic cylinder, the two side clamps are rotated and clamped to fix the seed tray, maintaining the stability of the seed tray during the trimming process, thereby improving the trimming effect.

[0013] Furthermore, the conveying assembly includes a second bracket, which is fixedly connected to one outer wall of the L-shaped conveyor platform. A second drive motor is fixedly connected to the outer wall of the second bracket, which is located on the side of the conveyor frame. The power output shaft of the second drive motor is connected to a special-shaped gear via a coupling. A rack meshes with the surface of the special-shaped gear. A connecting frame is fixedly connected to the outer wall of the rack near the conveyor frame. A moving block is fixedly connected to the bottom surface of the rack. A second spring is fixedly connected to the outer wall of the moving block away from the conveyor frame. A third bracket is fixedly connected to both ends of the bottom surface of the L-shaped conveyor platform. The end of the second spring away from the moving block is fixedly connected to the outer wall of the third bracket away from the conveyor frame. Guide rods are fixedly connected to both ends of the outer walls of the two third brackets that are close to each other. Guide frames are fixedly connected to both outer walls of the moving block. The guide frames have sliding holes inside and slide on the surface of the guide rods through the sliding holes.

[0014] With the conveying component in place, the second drive motor moves the seedling tray to one side of the trimming table. The seedling in the tray comes into contact with the electric chainsaw, which trims off the top of the seedling. This achieves automated transport and trimming operations, saving time and effort and greatly reducing the workload of operators. After the first seedling in the tray is trimmed, the second drive motor continues to drive, causing the rack to return to its initial position.

[0015] The beneficial effects of this invention are as follows:

[0016] As can be seen from the above, the plug seedling stem and leaf pruning device provided by the present invention has automated transfer and pruning operations, which saves time and effort, greatly reduces the workload of operators, and the plug seedlings on both sides are pruned alternately, eliminating waiting time and improving the pruning efficiency of plug seedlings.

[0030] Please see Figures 1-7 This invention provides a stem and leaf pruning device for plug seedlings, comprising a pruning table 1, an mounting frame 2 fixedly connected to one side of the top surface of the pruning table 1, a guide rail 3 fixedly connected to the outer wall of the mounting frame 2, a slide seat 4 slidably disposed on the surface of the guide rail 3, an electric chainsaw 5 fixedly connected to the outer wall of the slide seat 4, the electric chainsaw 5 being disposed above the pruning table 1, two symmetrically arranged L-shaped conveyor tables 6 fixedly connected to the outer walls of both sides of the pruning table 1, a transfer frame 7 slidably disposed on the L-shaped conveyor table 6, a transfer component 8 disposed on the transfer frame 7, a conveying frame 9 fixedly connected to the top surface of the L-shaped conveyor table 6, the transfer frame 7 and the conveying frame 9 being disposed opposite each other, a fixing component 10 disposed inside the conveying frame 9, a conveying component 11 disposed on the L-shaped conveyor table 6, and the fixing component 10 and the conveying component 11 being disposed on both sides of the pruning table 1.

[0031] Specifically, the position of the slide block 4 on the guide rail 3 is pre-adjusted according to the height of the seedlings in the plug trays. The height of the electric chainsaw 5 is changed, and the electric chainsaw 5 is started. The plug trays containing the seedlings are placed between multiple partitions in the transfer frame 7. The transfer component 8 is adjusted to transfer the first plug tray into the fixing component 10. Then, the transfer component 8 is returned to its initial position, and the second plug tray is simultaneously transferred to the initial position of the first plug tray. Then, the fixing component 10 is adjusted to clamp and fix the first plug tray. The control adjustment conveying component 11 is controlled to convey the first plug tray onto the pruning table 1. During the delivery process, the seedlings in the plug trays come into contact with the electric chainsaw 5. The chainsaw 5 is used to trim and remove the top of the seedlings, realizing automated transfer and trimming operations, saving time and labor, and greatly reducing the workload of operators. After the first seedling in the plug tray is trimmed, the first plug tray is returned to the L-shaped conveyor table 6. At this time, the seedlings on the other L-shaped conveyor table 6 are trimmed according to the above operation. The seedlings on both sides are trimmed alternately, saving waiting time and improving the trimming efficiency of the seedlings. Then, the seedlings on multiple plug trays can be trimmed in sequence according to the above steps.

[0032] Reference Figure 1 , Figure 2 and Figure 3In a preferred embodiment, the transfer frame 7 is U-shaped, with multiple equally spaced partitions fixedly connected to the inner walls of both sides. The transfer assembly 8 includes a support frame 801, which is fixedly connected to one end of the bottom surface of the L-shaped conveyor table 6. A drive motor 802 is fixedly connected to the outer wall of the support frame 801. The power output shaft of the drive motor 802 is connected to a threaded screw 803 via a coupling. A lifting seat 804 is threadedly connected to the surface of the threaded screw 803. A guide rod 805 is fixedly connected to one end of the top surface of the L-shaped conveyor table 6, and the lifting seat 804 is slidably disposed on the guide rod 805. 05 surface; a hydraulic cylinder 806 is fixedly connected to one end of the outer wall of the lifting seat 804 away from the guide rod 805, and fixed plates 807 are fixedly connected to both outer walls of the transfer frame 7. The output end of the hydraulic cylinder 806 is fixedly connected to the outer wall of one fixed plate 807; a guide hole is opened on the outer wall of the other fixed plate 807 on the transfer frame 7, and a guide rod 808 is fixedly connected to one end of the outer wall of the lifting seat 804 away from the guide rod 805. The fixed plate 807 is slidably set on the surface of the fixed plate 807 through the guide hole. The hydraulic cylinder 806 and the guide rod 808 are symmetrically distributed at both ends of the transfer frame 7.

[0033] Specifically, the tension adjustment hydraulic cylinder 806 causes the transfer frame 7 to move closer to the fixed component 10 along the surface of the L-shaped conveyor table 6. When the first cavity plate moves into the interior of the fixed component 10, the second cavity plate simultaneously moves to the initial position of the first cavity plate. The drive motor 802 is started to rotate the threaded screw 803, and the transfer frame 7 moves upward to the upper end of the cavity plate. The retraction adjustment hydraulic cylinder 806 causes the transfer frame 7 to return to the position above the initial position. The drive motor 802 is reversed to cause the transfer frame 7 to descend back to the side of the cavity plate, completing the transfer of one cavity plate. The subsequent cavity plates are then moved forward a certain distance in sequence. This cycle can be repeated to achieve the transfer operation of multiple cavity plates.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, the fixing component 10 includes a movable groove 1001, which is formed inside the transport frame 9. A hydraulic cylinder 1002 is fixedly connected to the inner wall of the movable groove 1001. A clamping slide 1003 is fixedly connected to the output end of the hydraulic cylinder 1002. Two spaced guide blocks 1004 are fixedly connected to the inner wall of the bottom surface of the transport frame 9. The clamping slide 1003 is slidably disposed within the movable groove 1001 and between the two guide blocks 1004. Two symmetrically arranged triangular wedges 1005 are fixedly connected to the outer walls of both sides of the clamping slide 1003. Two side clamping plates 1005 are rotatably arranged inside the transport frame 9 about the clamping slide 1003. 006, a turning hole is provided in the middle of the side clamping plate 1006, and two balance rotating rods 1007 are fixedly connected to the bottom surface of the conveying frame 9. The side clamping plate 1006 is rotatably set on the surface of the balance rotating rods 1007 through the turning hole. A spring 1008 is fixedly connected to the outer wall of the side clamping plate 1006 away from the clamping slide 1003. The end of the spring 1008 away from the side clamping plate 1006 is fixedly connected to the inner wall of the side of the conveying frame 9. A fixing hole is provided inside the bottom surface of the conveying frame 9, and a fixing rod 1009 is fixedly connected inside the fixing hole. A connecting frame 1010 is fixedly connected to the end of the fixing rod 1009 away from the conveying frame 9. The connecting frame 1010 is slidably set on the top surface of the L-shaped conveying table 6.

[0035] Specifically, after the first pruning tray is transferred between the two side clamping plates 1006, the second hydraulic cylinder 1002 is stretched and adjusted, causing the clamping slide 1003 to move the triangular wedge block 1005 to one side of the pruning tray. The triangular wedge block 1005 presses against the outer wall of the side clamping plate 1006 away from the pruning tray. Under the action of the balance rotating rod 1007, the two side clamping plates 1006 rotate and clamp and fix the pruning tray, maintaining the stability of the pruning tray during the pruning process, thereby improving the pruning effect.

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7In a preferred embodiment, the conveying assembly 11 includes a second support 1101, which is fixedly connected to one side outer wall of the L-shaped conveyor table 6. A second drive motor 1102 is fixedly connected to the outer wall of the second support 1101. The second drive motor 1102 is located on the side of the conveying frame 9. The power output shaft of the second drive motor 1102 is connected to a special-shaped gear 1103 via a coupling. The teeth of the special-shaped gear 1103 are arranged at 300° around its outer wall. A rack 1104 meshes with the surface of the special-shaped gear 1103. A connecting frame 1010 is fixedly connected to the outer wall of the rack 1104 near the conveying frame 9. The bottom surface of the rack 1104 is fixed... A movable block 1105 is fixedly connected. A spring 1106 is fixedly connected to the outer wall of the movable block 1105 on the side away from the conveyor frame 9. A bracket 1107 is fixedly connected to both ends of the bottom surface of the L-shaped conveyor table 6. The end of the spring 1106 away from the movable block 1105 is fixedly connected to the outer wall of the bracket 1107 on the side away from the conveyor frame 9. Guide rods 1108 are fixedly connected to both ends of the outer wall of the two brackets 1107 on the side close to each other. Guide frames 1109 are fixedly connected to both outer walls of the movable block 1105. A sliding hole is opened inside the guide frame 1109. The guide frame 1109 is slidably set on the surface of the guide rod 1108 through the sliding hole.

[0037] Specifically, after the seedling trays are fixed, the drive motor 1102 is started to rotate the shaped gear 1103. The shaped gear 1103 meshes with the rack 1104, causing the rack 1104 to drive the fixing assembly 10 and the seedling trays fixed inside it to move towards the trimming table 1. During the movement of the seedling trays, the seedlings on them come into contact with the electric chainsaw 5. The electric chainsaw 5 is used to trim and remove the tops of the seedlings, realizing automated transfer and trimming operations, saving time and effort, and greatly reducing the workload of the operators. After the first seedling on the seedling tray is trimmed, the drive motor 1102 is driven again to rotate the shaped gear 1103. The tooth disengages from the rack 1104, and under the elastic action of the second spring 1106, the rack 1104 returns to its initial position, bringing the first seedling tray back onto the L-shaped conveyor table 6. Then, with the help of the adjusting and fixing component 10, the seedling tray with the trimmed seedlings can be removed. At the same time, the seedling trays on the other side of the L-shaped conveyor table 6 are transferred, fixed, and trimmed according to the above operation. The seedling trays on both sides are trimmed alternately, saving waiting time and improving the trimming efficiency of the seedling trays. When trimming the seedling trays on the other side, the seedling trays on the opposite side are transferred and fixed according to the above steps, waiting for trimming. This cycle is repeated to achieve uninterrupted trimming.

[0038] Working principle: The position of the slide block 4 on the guide rail 3 is pre-adjusted according to the height of the seedlings. The height of the electric chainsaw 5 is changed, and the chainsaw 5 is started. The seedling trays are placed between multiple partitions within the transfer frame 7. The hydraulic cylinder 806 is extended, causing the transfer frame 7 to move closer to the fixed assembly 10 along the surface of the L-shaped conveyor table 6. When the first seedling tray moves into the interior of the fixed assembly 10, the second seedling tray simultaneously moves to the initial position of the first seedling tray. The drive motor 802 is started, causing the threaded screw 803 to rotate, and the transfer frame 7 moves upward to the top of the seedling tray. The hydraulic cylinder 806 is then retracted, causing the transfer frame 7 to return to its original position. Initially, the reverse drive motor 802 lowers the transfer frame 7 back to the side of the pruning tray, completing the transfer of one pruning tray. The subsequent pruning trays are then moved forward a certain distance in sequence. This cycle repeats to transfer multiple pruning trays. After the first pruning tray is transferred between the two side clamping plates 1006, the tension adjustment hydraulic cylinder 1002 is activated, causing the clamping slide 1003 to move the triangular wedge 1005 towards one side of the pruning tray. The triangular wedge 1005 presses against the outer wall of the side clamping plate 1006 away from the pruning tray. Under the action of the balance rotating rod 1007, the two side clamping plates 1006 rotate and clamp and fix the pruning tray, maintaining the trimming process. The stability of the seedling tray is improved, thereby enhancing the pruning effect. After the seedling tray is fixed, the drive motor 1102 is started to rotate the shaped gear 1103. The shaped gear 1103 meshes with the rack 1104, causing the rack 1104 to drive the fixing component 10 and the seedling tray fixed inside it to move towards the pruning table 1. During the movement of the seedling tray, the seedlings on it come into contact with the electric chainsaw 5. The electric chainsaw 5 is used to trim and remove the top of the seedlings, realizing automated transfer and pruning operations, saving time and effort, and greatly reducing the workload of the operators. After the pruning of the seedlings on the first seedling tray is completed, the drive motor 1102 is driven again to rotate the shaped gear 1103. The teeth on wheel 1103 disengage from rack 1104, and under the elastic action of spring 1106, rack 1104 returns to its initial position, bringing the first seedling tray back onto L-shaped conveyor table 6. Then, with the help of adjusting and fixing component 10, the seedling tray with the trimmed seedlings can be removed. At the same time, the seedling trays on the other side of L-shaped conveyor table 6 are transferred, fixed, and trimmed according to the above operation. The seedling trays on both sides are trimmed alternately, saving waiting time and improving the trimming efficiency of seedling trays. When trimming the seedling trays on the other side, the seedling trays on the opposite side are transferred and fixed according to the above steps, waiting for trimming. This cycle is repeated to achieve uninterrupted trimming.
