Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to a seedling string weaving machine. Background Technology

[0002] Sweet potato seedlings should be planted using the transplanting method. When planting, choose a plot of land that is high in elevation, with deep soil and good drainage. Deeply cultivate and finely prepare the soil to ensure it is loose. After land preparation, create raised beds to improve drainage. Select healthy, disease-free, high-quality seedlings with thick stems and short, dense internodes, retaining an appropriate number of stem nodes for cuttings. When planting, insert the seedlings obliquely into the middle of the raised bed, ensuring a reasonable number of stem nodes are embedded in the soil. The plant spacing needs to be adjusted flexibly according to the variety characteristics and soil conditions. Use a single-plant, equidistant planting method, and water immediately after planting to ensure seedling survival. Currently, the transplanting of sweet potato seedlings mainly relies on manual labor or semi-automatic transplanters. Manual transplanting is labor-intensive, has low planting precision, and is costly for large-scale operations. While semi-automatic transplanters reduce labor intensity, they require manual assistance in feeding seedlings and have limited efficiency. They also have high equipment investment and maintenance costs, and therefore do not offer a significant advantage over traditional methods. Therefore, there is an urgent need to develop new and efficient planting equipment and supporting technologies to break through existing bottlenecks. Summary of the Invention

[0014] The beneficial technical effects of this invention are: (1) The two single-line weaving device of the present invention drives two turntables to rotate two weaving brackets to continuously wind and form two thick ropes. During the process of weaving the two thick ropes, seedlings are intermittently put into the winding and weaving part of the thick ropes.

[0019] Example 1, see appendix Figure 1-16A seedling weaving machine includes two single-thread weaving devices 01 arranged side-by-side on a frame 001 and a seedling feeding device placed on one side of the frame 001. Each single-thread weaving device 01 includes a round tube base 2, a turntable 3, a weaving support 37, a guide mechanism 04, and a thread feeding mechanism 05. The round tube base 2 is fixed to one end of a support 1, and a flange is provided at the end of the round tube base 2. The round tube base 2 is vertically fixed to the support 1 through the flange. Several reinforcing ribs are evenly distributed between the flange and the tube body. A rotating shaft 31 is coaxially mounted on one end face of the turntable 3. The rotating shaft 31 is coaxially rotatably fitted inside the round tube base 2. Two guide mechanisms 04 and two thread feeding mechanisms 05 are evenly distributed on the end face of the turntable 3 outside the rotating shaft 31. The spool 481 of the braided rope 48 is installed in the wire feeding mechanism 05 and introduced from the wire feeding mechanism 05 into the guide mechanism 04. The guide mechanism 04 and the wire feeding mechanism 05 are arranged in a cross shape. The support 1 is provided with a drive mechanism connected to the rotating shaft 31. The drive mechanism includes a geared motor 11, a drive pulley 12, a driven pulley 13 and a synchronous belt 14. The geared motor 11 is located at the end of the support 1. The drive pulley 12 is connected to the output shaft of the geared motor 11. The driven pulley 13 is connected to the rotating shaft 31. The synchronous belt 14 is fitted between the drive pulley 12 and the driven pulley 13. The drive mechanism drives the rotating shaft 31 to rotate, thereby driving the turntable 3 and the braiding bracket 37 to rotate synchronously.

[0020] A fixed gear 21 is fixedly installed at the end of the round tube seat 2. The fixed gear 21 meshes with the driven gear 47 on the drive mechanism. As the drive mechanism rotates with the turntable 3, the driven gear 47 meshes and rotates relative to the fixed gear 21, providing power to the guide mechanism 04. The braided bracket 37 includes a central rod 32 and a synchronous lever. A bushing 34 is provided in the middle of the synchronous lever. The bushing 34 is fixedly fitted on the central rod 32. The central rod 32 is coaxially fixedly connected to the other end face of the turntable 3. The central rod 32 and the turntable 3 rotate synchronously. Several threading holes 35 are evenly provided on the synchronous lever. The braided ropes 48 coming out from the two guide mechanisms 04 enter the threading holes 35 at both ends of the synchronous lever.

[0021] The guiding mechanism 04 includes a triangular frame 41, a hollow shaft 42, a support wheel 43, and a pressure wheel 44 fixed on the turntable 3. A fixed shaft 50 is vertically connected to the turntable 3. The triangular frame 41 is mounted on the fixed shaft 50 and fixed with a nut. Circular seats 46 are provided at both ends of one side of the triangular frame 41. The hollow shaft 42 is rotatably fitted between the through holes in the centers of the two circular seats 46. First bearings 49 are installed in the through holes at both ends of the circular seats 46. The hollow shaft 42 is rotatably fitted between the two first bearings 49. The hollow shaft 42 can also be directly rotatably fitted between the two through holes. The hollow shaft 42 passes vertically through the turntable 3 and corresponds to the threading hole 35 on the braided bracket 37. A seated bearing 36 is provided between the hollow shaft 42 and the turntable 3. The support wheel 43 is coaxially fixed between the two circular seats 46. On the hollow shaft 42, the middle of the tripod body 41 is provided with a cable routing hole 411 facing the support wheel 43. The braided rope 48 is wound around the outer side of the support wheel 43 through the cable routing hole 411. The pressure roller 44 is rotatably mounted between the edges of the inner sides of the two circular seats 46 and is arranged facing the support wheel 43. A cable routing gap is left between the rolling surface of the pressure roller 44 and the rolling surface of the support wheel 43. The size of the cable routing gap is slightly smaller than the diameter of the braided rope 48 to ensure that the braided rope 48 can pass through the cable routing gap after being compressed and deformed. The driven gear 47 is mounted on the hollow shaft 42. At least two pressure rollers 44 are evenly distributed along the circumference of the circular seats 46. Multiple pressure rollers 44 are arranged in the circumferential direction of the support wheel 43 to increase the pressure area of ​​the braided rope 48 on the support wheel 43 and improve the rolling friction force on the braided rope 48.

[0022] A helical wheel 421 is fixedly installed in the middle of the hollow shaft 42. A support wheel 43 is fixedly installed between the two limiting wheels of the helical wheel 421. An annular groove 422 is formed between the two limiting wheels and the outer surface of the support wheel 43. The support wheel 43 is connected to the hollow shaft 42 through the helical wheel 421 to form a modular component assembly structure, which is easy to process and manufacture and reduces costs. The annular groove 422 is used to provide a limit for the braided rope 48, restricting it between the support wheel 43 and the pressure wheel 44, and preventing the braided rope 48 from slipping off between the support wheel 43 and the pressure wheel 44.

[0023] The end of the tripod body 41 is provided with an arc-shaped boss 412. The outer side of the arc-shaped boss 412 is provided with an arc-shaped guide groove 413. One end of the arc-shaped guide groove 413 corresponds to the port of the hollow shaft 42, and the other end corresponds to the cable routing hole 411 inside the tripod body 41. The braided rope 48 is wound around the support wheel 43 and pressed tightly to the outer side of the support wheel 43 by the pressure wheel 44. After the support wheel 43 rotates, the braided rope 48 will rotate with the support roller under the action of the rolling friction of the pressure wheel 44 and the support wheel 43. The braided rope 48 generates a certain pulling force, and then the braided rope 48 is sent out into the arc-shaped guide groove 413. The arc-shaped guide groove 413 provides arc-shaped guiding support for the braided rope 48, so that it can smoothly enter the hollow shaft 42 after adjusting its direction.

[0024] The arc-shaped boss 412 has a U-shaped sleeve 414 in the middle that fits on the outside of the arc-shaped guide groove 413. The U-shaped sleeve 414 forms a limiting protection structure on the outside of the arc-shaped guide groove 413 to prevent the braided rope 48 from slipping out of the arc-shaped guide groove 413, thus ensuring the high-efficiency and stable operation of the guide mechanism 04.

[0025] The working process and principle of this embodiment are as follows: ① The drive mechanism of the two single-thread braiding devices 01 is started synchronously, and the drive mechanism drives the rotating shaft 31 to rotate inside the round tube seat 2. ② The rotating shaft 31 rotates the turntable 3, and the driven gear 47 on the two guide mechanisms 04 rotates around the fixed gear 21 at the end of the round tube seat 2, driving the hollow shaft 42 in the guide mechanism 04 to rotate relative to the round seat 46. ③ The hollow shaft 42 drives the I-beam wheel 421 and the support wheel 43 to rotate synchronously. When the support wheel 43 rotates, the pressure wheel 44 rotates accordingly to press the braided rope 48 against the surface of the support wheel 43. The friction generated between the two... The braided rope 48 rotates with the support wheel 43; ④ The braided rope 48 generates pulling force, the unwinding mechanism 05 rotates to unwind, and the braided rope 48 continuously enters from the thread hole 411 between the pressure wheel 44 and the support wheel 43, and is then conveyed out from between the pressure wheel 44 and the support wheel 43 into the arc-shaped guide groove 413; ⑤ The arc-shaped guide groove 413 provides arc-shaped support and guidance for the braided rope 48, allowing it to smoothly enter the hollow shaft 42, and then be led out from the hollow shaft 42 into the threading hole 35 on the braiding bracket 37; ⑥ After the threading rope is led out, the drive mechanism stops, and the outer ends of the two braided ropes 48 on the braiding bracket 37 are knotted. Connect the two braided ropes 48 and apply a horizontal tension outward from the knot. The two braided ropes 48 are tensioned and form a triangular hole with the synchronizing lever. ⑦ Restart the drive mechanism to drive the two turntables 3 and the braiding bracket 37 to rotate at the same angle and speed, while continuously pulling the braided ropes 48 on the two braiding brackets 37 outward. The two braided ropes 48 are continuously pulled outward and spirally intertwined to form a thick rope body 82. Two parallel thick rope bodies 82 are formed between the two braiding brackets 37. ⑧ Stop the rotation of the turntables 3 during the weaving of the thick rope body 82, so that the triangular hole formed by the braided ropes 48 on the two braiding brackets 37 is formed. The holes correspond to each other, and the seedlings 81 are placed between the two triangular holes through the seedling feeding device; ⑨ Drive the two turntables 3 to rotate synchronously again to weave the thick rope 82. One end of the seedling 81 is wrapped and woven into the thick rope 82 formed by the weaving support 37 on one side, and the other end is wrapped and woven into the thick rope 82 formed by the weaving support 37 on the other side; ⑩ According to steps ⑦-⑨, control the turntables 3 to rotate intermittently at a fixed rate. The two thick ropes 82 are woven and wound at a fixed speed, and the seedlings 81 are placed between the two triangular holes intermittently at a fixed rate. The seedlings 81 are woven in series at equal intervals between the two thick ropes 82.

[0026] Example 2, see appendix Figure 9-11 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that both the support wheel 43 and the pressure wheel 44 are gears. The braided rope 48 is subjected to the pressure of the gears, which will cause it to bend and deform and be pressed into the tooth groove between the gear teeth. This greatly increases the friction of the braided rope 48 between the support wheel 43 and the pressure wheel 44, thereby increasing the pulling and guiding power of the braided rope.

[0027] Furthermore, in this embodiment, the support wheel 43 is set as an elastic rubber gear. After being compressed, the rubber gear will produce a certain elastic deformation, which avoids the meshing force between the gears from damaging the braided rope 48 and ensures that the braided rope has sufficient strength to braid the sweet potato seedlings 81. At the same time, the deformation of the rubber gear itself can make it fit more fully with the braided rope 48, further improving the friction between the braided rope 48 and the gear.

[0028] Example 3, see appendix Figure 12-13 16. This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that an auxiliary pressing mechanism is provided between the pressure roller 44 and the circular seat 46. The auxiliary pressing mechanism includes a shaft hole 462 provided on the inner side edge of the circular seat 46, a spring 452, and a limiting stud 451. The cross-section of the shaft hole 462 is oblong. The wheel axles 441 on both sides of the pressure roller 44 are fitted into the two shaft holes 462. The wheel axles 441 of the pressure roller 44 have a radial sliding allowance in the shaft hole 462. A radial hole 461 is provided on the circumferential side of the circular seat 46, which extends to the shaft hole 462. The spring 452 is fitted into the radial hole 461. The limiting stud 451 is threaded to the upper port of the radial hole 461 and presses the spring 452. The limiting stud 451 presses the spring 452 into the radial hole 461, thereby pressing the spring 452 onto the surface of the wheel axle 441.

[0029] The end face of the limiting stud 451 is provided with a guide shaft 453. The guide shaft 453 extends into the inside of the spring 452. The guide shaft 453 provides guidance for the spring 452, preventing the spring 452 from bending in the radial hole 461 and ensuring that it has stable and sufficient elastic force.

[0030] The principle and function of the auxiliary pressing mechanism in this embodiment are as follows: During the rotation and movement of the braided rope 48 between the support wheel 43 and the pressure wheel 44, the spring 452 provides pressure to the wheel axle 441 of the pressure wheel 44, so that the wheel axle 441 has a certain elastic movement margin in the shaft hole 462 with an elongated cross-section. This allows the pressure wheel 44 to provide elastic pressure to the braided rope 48, enabling it to rise and fall with the fluctuation of the tension on the braided rope 48 and the irregular side structure of the braided rope 48, providing dynamic pressing force to the braided rope 48 and avoiding excessive rolling pressure of the pressure wheel 44 from damaging the braided rope 48.

[0031] Example 4, see appendix Figure 5 , 17-22, a wire feeding mechanism 05 in an embodiment includes a fixed frame and a rotating frame; the main body of the fixed frame is a supporting optical shaft 5, one end of the supporting optical shaft 5 is provided with a supporting plate 51, the edge of the supporting plate 51 is evenly distributed with a plurality of mounting holes 52, and the mounting holes 52 are provided with locking bolts 521, the supporting plate 51 is fixed to the bearing plate by the locking bolts 521, the bearing plate is the turntable 3 on the braiding equipment; the main body of the rotating frame is a tube shaft 6, the length of the tube shaft 6 is the same as the length of the supporting optical shaft 5, the two are sleeved together and the end faces are in a flush state, one end of the tube shaft 6 is integrally connected with a fixed end plate 61, and the other end is connected with a movable end plate 62, the fixed end plate 61 and the movable end plate 62 form an I-shaped wheel structure, the tube shaft 6 is rotatably sleeved on the supporting optical shaft 5; the other end of the supporting optical shaft 5 is provided with a limiting plate 53, the rotating frame is restricted in the fixed frame by the limiting plate 53.

[0032] The supporting optical shaft 5 is a hollow structure. A hollow tube 54 is installed in the coaxial sleeve 34 inside the supporting optical shaft 5. One end of the hollow tube 54 is fixed to the supporting plate 51. The center of the limiting plate 53 is provided with a through hole. A locking bolt 71 is installed in the through hole and the hollow tube 54. After the rotating frame is installed into the fixed frame, the limiting plate 53 is fitted onto the end of the locking bolt 71. The limiting plate 53 is tightened by the nut, pressing the limiting plate 53 against the end face of the supporting optical shaft 5 and the tube shaft 6.

[0033] The fixed end plate 61 and the movable end plate 62 are the same size, the support plate 51 and the limiting plate 53 are the same size, and the size of the fixed end plate 61 is smaller than the size of the support plate 51.

[0034] The installation method of the braided rope 48 synchronous wire feeding bracket in this embodiment is as follows: the rope coil of the braided rope 48 is fitted onto the tube shaft 6, a movable end plate 62 is installed at the end of the tube shaft 6, the rope coil is pressed between the movable end plate 62 and the fixed end plate 61, then the tube shaft 6 with the rope coil is fitted onto the support optical shaft 5, a locking bolt 71 is installed in the hollow tube 54 inside the support optical shaft 5, and the through hole in the center of the limiting plate 53 is fitted into the end of the locking bolt 71. The limiting plate 53 is pressed between the end faces of the support optical shaft 5 and the tube shaft 6 by the nut, thus completing the installation.

[0035] Several arc-shaped baffles 55 are evenly distributed along the inner edge of the support plate 51. The number of arc-shaped baffles 55 is set according to the requirements. The arc-shaped baffles 55 are coaxially arranged with the support plate 51, and the end face of the arc-shaped baffles 55 is supported on the limiting plate 53. One of the arc-shaped baffles 55 has a threading hole 56 at its end, which is arranged along the circumference of the support plate 51. After the rope coil of the braided rope 48 is fitted into the rotating frame, the evenly distributed arc-shaped baffles 55 can form a blocking and protective structure in the circumference of the rope coil. At the same time, the threading hole 56 on the arc-shaped baffles 55 allows the braiding to be released in a fixed position, which effectively improves the stability of the rope coil 481 release and avoids the phenomenon of the rope coil becoming loose and separated during synchronous release.

[0036] The outer surface of the tube shaft 6 is evenly distributed with several raised ribs 63. The raised ribs 63 gradually increase in height from one end of the movable end plate 62 to one end of the fixed end plate 61. The through hole in the center of the rope coil is a circular hole. This raised rib 63 structure allows the circular hole to be gradually pressed and tightened after the rope coil is sleeved on the tube shaft 6, and to produce a certain deformation, ensuring the stability of the rope coil sleeve.

[0037] The movable end plate 62 has a socket hole 64 at its center, and the end of the tube shaft 6 has an external thread 65. The socket hole 64 is fitted into the end of the tube shaft 6 and fixedly connected by the thread. The movable end plate 62 with the threaded connection structure makes it easy for the rope coil to be quickly pressed and fixed after it is put on the tube shaft 6. The movable end plate 62 can be quickly disassembled by rotating it, realizing the quick installation and disassembly of the rope coil and improving the convenience of operation.

[0038] Example 5, see appendix Figure 1 , 23 -25, a seedling delivery device in an embodiment includes a belt conveyor 91 and a pushing mechanism; the pushing mechanism includes a linear module 92, a flipping motor 94 and a seedling delivery bracket. The end of the belt conveyor 91 is provided with a support base 93. The linear module 92 is fixedly installed on the surface of the support base 93. The length direction of the linear module 92 is consistent with the width direction of the belt conveyor 91. The flipping motor 94 is fixed on the surface of the slider 921 of the linear module 92, so that the flipping motor 94 can move synchronously in a straight line on the linear module 92 with the slider 921. The seedling delivery bracket is fixedly connected to the output shaft of the flipping motor 94. The seedling delivery bracket is driven to rotate by the flipping motor 94. The position of the seedling delivery bracket corresponds to the output end of the belt conveyor 91. The seedlings 81 are placed on the belt 911 and conveyed forward. When the seedlings 81 reach the end of the belt 911, they will detach from the belt 911 and fall downward. The seedling delivery bracket catches the falling seedlings 81.

[0039] The belt conveyor 91 has several seedling seats evenly spaced along the width direction of the belt 911. Each seedling seat consists of two limiting bosses 912. There is a seedling gap between the two limiting bosses 912. The seedling gap is used to accommodate and place the seedlings 81. The seedling seats are used to fix the seedlings 81 on the belt 911 and transport them at equal intervals.

[0040] The seedling feeding support includes a main shaft 951 and at least two V-shaped frame bodies 96. The main shaft 951 is coaxially and fixedly connected to the output shaft of the flipping motor 94. The length direction of the main shaft 951 is consistent with the length direction of the linear module 92. The V-shaped frame bodies 96 are evenly connected to the main shaft 951. The V-shaped groove structure formed between the V-shaped frame bodies 96 can stably support the seedlings 81. The flipping motor 94 drives the main shaft 951 to rotate, and the main shaft 951 drives the V-shaped frame bodies 96 to rotate, thereby flipping and tilting the seedlings 81 out from between the V-shaped frame bodies 96.

[0041] Both ends of the linear module 92 are equipped with U-shaped photoelectric switches 922. The side of the slider 921 is equipped with an L-shaped limiting plate 923 corresponding to the position of the U-shaped photoelectric switch 922. When the seedling feeding bracket moves with the slider 921 to the front of the belt conveyor 91, the L-shaped limiting plate 923 triggers the U-shaped photoelectric switch 922 at one end, and the linear module 92 stops working. The seedling feeding bracket receives the seedling 81. When the seedling feeding bracket moves forward with the slider 921 to send the seedling 81 into the weaving equipment, the L-shaped limiting plate 923 triggers the U-shaped photoelectric switch 922 at the other end, and the linear module 92 stops working. The seedling feeding bracket is driven to flip by the flipping motor 94, and the seedling 81 is tilted out. The linear module 92 moves back and forth to drive the seedling feeding bracket to receive and feed the seedlings.

[0042] In this embodiment, when the seedling feeding device is working, the seedlings 81 are placed in the gap between the upper limit bosses 912 of the belt 911. The seedlings 81 are conveyed forward by the belt 911. When the seedlings 81 reach the end of the belt conveyor 91, they will detach from the belt 911 and fall downwards. At this time, the seedling feeding bracket located below catches the seedlings 81, and the seedlings 81 enter the V-shaped frame 96 on the main shaft 951. Then, the linear module 92 is activated to push the flipping motor 94 and the seedling feeding bracket laterally. The seedlings 81 are automatically fed into the outer ends of the two woven brackets 37 along with the seedling feeding bracket. Between the triangular holes of the braided rope 48 (when pushing the seedlings 81, the two braiding supports 37 are controlled to be vertical, and the two triangular holes are both vertical and correspond to each other, so that the seedlings 81 can be pushed horizontally into the two triangular holes by the straight module 92), the flipping motor 94 is then started. The flipping motor 94 drives the seedling feeding support to automatically flip, tilting the seedlings 81 out and automatically weaving them into the thick rope body 82, which effectively improves the efficiency of the seedling weaving operation. Moreover, this equal-interval, timed and quantitative seedling feeding method can ensure the plant spacing of the seedlings 81 and improve the weaving quality of the seedlings 81.

[0043] The V-shaped frame 96 is designed to include two inclined baffles 961, which are symmetrically clamped on both sides of the main shaft 951 in a V-shape. The outer inclined baffle 961 can be longer than the inner inclined baffle 961. The outer inclined baffle 961 can provide a larger range of blocking effect, improve the receiving effect of the seedlings 81, and prevent accidental material drop. The lower end of the inclined baffle 961 is provided with a through hole, and the main shaft 951 is provided with a radial hole 461. A fastening bolt 962 is installed between the through hole and the radial hole 461 to fix the inclined baffle 961 to the main shaft 951. The tightening force of the fastening bolt 962 tightens and fixes the two inclined baffles 961 to the main shaft 951, so that the two inclined baffles 961 form a V-shaped plate structure.

[0044] An auxiliary bolt 963 is provided above the fastening bolt 962. The auxiliary bolt 963 is connected between the middle of the two inclined baffles 961. The auxiliary bolt 963 is pressed against the upper side of the main shaft 951. The auxiliary bolt 963 assists the fastening bolt 962 in fixing the inclined baffles 961, thereby improving the installation stability of the inclined baffles 961.
