Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to a single-thread weaving device for rice seedlings. Background Technology

[0002] Sweet potatoes are planted using a single-hole, equidistant planting method. During planting, the planting area is deeply tilled to create a loose, well-aerated topsoil layer. Standardized ridges are then constructed, with a ridge height of 25-30 cm and a ridge spacing of 70-80 cm. This three-dimensional cultivation structure prevents waterlogging and promotes tuber enlargement. At transplanting, a slanted planting method is used, burying the middle 2-3 nodes of the sweet potato seedling in the center of the ridge. Plant spacing is adjusted flexibly according to variety characteristics and soil fertility to ensure sufficient nutrient space for each plant. Immediately after planting, water thoroughly to help the roots establish, and follow with subsequent water management to ensure a high survival rate.

[0003] Currently, this planting method mainly relies on manual labor or semi-automatic transplanters. While manual planting is flexible, it has significant drawbacks: firstly, it is extremely labor-intensive, leading to high labor costs in large-scale planting scenarios; secondly, due to the lack of precise control tools, it is difficult to maintain consistent seedling insertion depth and spacing, affecting the final planting results. Semi-automatic transplanters can alleviate the burden on workers to some extent, but they still have many limitations. They require manual assistance in delivering the seedlings, and the coordination between the driver and the delivery personnel directly affects the smoothness of the operation. To ensure the seedlings are inserted to the correct depth, the transplanter's speed is forced to slow down, resulting in limited improvement in planting efficiency. Furthermore, the equipment purchase cost and subsequent maintenance costs remain high. Overall, compared to manual seedling planting, its cost advantage is not significant. Therefore, it is necessary to improve the existing sweet potato planting method and design corresponding planting auxiliary equipment. Summary of the Invention

[0011] Preferably, an auxiliary clamping mechanism is provided between the pressure roller and the circular base. The auxiliary clamping mechanism includes a shaft hole, a spring, and a limiting stud provided on the inner side edge of the circular base. The shaft hole is a blind hole with an oblong cross-section. The length direction of the oblong shaft hole is consistent with the radial direction of the circular base.

[0015] The beneficial technical effects of this invention are: (1) The present invention drives the rotating shaft to rotate in the round tube seat to drive the turntable to rotate. The two braiding brackets and two guiding mechanisms installed on the turntable rotate accordingly. At the same time, the driven gear can rotate relative to the guiding mechanism under the meshing action of the fixed gear on the round tube seat to drive the hollow shaft to rotate. The hollow shaft drives the support wheel to rotate to generate guiding power. Under the action of the pulling force and guiding power, the two braiding ropes enter the braiding bracket to weave the seedlings and weave the seedlings in series in a thick rope body. Therefore, the seedlings can be transplanted by laying them in series, which can greatly improve the seedling planting efficiency and reduce the planting cost.

[0016] (2) The guiding mechanism of the present invention winds the braided rope around the support wheel. The braided rope is pressed by a pressure wheel set on the outside of the support wheel. When the support wheel rotates, the braided rope will rotate with the support wheel due to the friction generated by the pressing, so that the braided rope generates a pulling force. The braided rope is sent out into the arc-shaped guide groove with the pulling force. The arc-shaped guide groove provides arc-shaped support and guidance for the braided rope, so that the braided rope can smoothly enter the hollow shaft and be led out for subsequent weaving operations. This design does not require a large pulling force to be applied to the braided rope to make it stably output for seedling weaving, avoids damage to the braided rope, and helps to ensure the quality of seedling weaving and improve weaving efficiency.

[0017] (3) The present invention only requires one drive mechanism to realize the synchronous drive of seedling weaving and weaving rope release, which is conducive to the miniaturization and lightweight design requirements of the weaving device, reduces equipment cost, and does not require multiple power sources to cooperate, which can improve the coordination accuracy of seedling release and weaving, and improve the weaving quality of seedlings.

[0020] Example 1, see appendix Figure 1-13 A single-line weaving device for rice seedlings includes a circular tube base 2, a turntable 3, a weaving support, a guide mechanism 04, and a thread feeding mechanism 05. The circular tube base 2 is fixed to one end of a support 1, and a flange is provided at the end of the circular tube base 2. The circular 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 provided on one end face of the turntable 3. The rotating shaft 31 is coaxially rotatably fitted inside the circular 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 weaving rope 48 is installed on the thread feeding mechanism 05. The wire is 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 equipped with a drive mechanism connected to the rotating shaft 31. The drive mechanism includes a motor 11, a drive pulley 12, a driven pulley 13 and a belt 14. The motor 11 is located at the end of the support 1. The drive pulley 12 is connected to the output shaft of the motor 11. The driven pulley 13 is connected to the rotating shaft 31. The belt 14 is fitted between the drive pulley 12 and the driven pulley 13. The rotating shaft 31 is driven to rotate through this drive mechanism, thereby driving the turntable 3 and the braiding bracket to rotate synchronously.

[0021] 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 with and rotates relative to the fixed gear 21, providing power to the guide mechanism 04.

[0022] 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. Two 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. Alternatively, the hollow shaft 42 can 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. A seated bearing 36 is provided between the hollow shaft 42 and the turntable 3. The support wheel 43 is coaxially fixedly installed between the two circular seats 46. On the spindle 42, the center 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.

[0023] The braided support includes a central rod 32 and a synchronous lever 33. A bushing 34 is provided in the middle of the synchronous lever, and the bushing 34 is fixedly fitted on the central rod 32. The central rod 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 33. The braided rope 48 coming out from the two guide mechanisms 04 enters the threading holes 35 at both ends of the synchronous lever 33 respectively.

[0024] 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.

[0025] The end of the tripod body 41 is provided with an arc-shaped boss 412, and the outer side of the arc-shaped boss 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 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 provides arc-shaped guiding support for the braided rope 48, so that it can smoothly enter the hollow shaft 42 after adjusting its direction.

[0026] 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.

[0027] The working process and principle of this embodiment are as follows: ① The drive mechanism drives the rotating shaft 31 to rotate inside the circular tube seat 2; ② The rotating shaft 31 rotates the turntable 3, and the driven gears 47 on the two guide mechanisms 04 rotate around the circumference of the fixed gear 21 at the end of the circular tube seat 2, driving the hollow shaft 42 inside the guide mechanism 04 to rotate relative to the circular 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, pressing the braided rope 48 against the surface of the support wheel 43. The friction generated between the two drives the braided rope 48 to rotate 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 the pressure wheel 44 and the support wheel 43 from the wire hole 411. Between the pressure roller 44 and the support roller 43, the rope 48 is conveyed into the arc-shaped guide groove 413; 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 be led out from the hollow shaft 42 into the threading hole 35 on the braiding bracket; the outer ends of the two braided ropes 48 on the braiding bracket are tied together, and a horizontal tension is applied to the two braided ropes 48 from the knot, so that the two braided ropes 48 are tensioned and form a triangular hole with the synchronizing lever 33; the two braided ropes 48 on the braiding bracket are pulled outward, and the two braided ropes 48 are continuously pulled outward and spirally wrapped around each other to form a thick rope body 91. During this process, seedlings 81 are placed into the triangular hole at intervals, and the seedlings 81 are wrapped and woven into a thick rope body 91.

[0028] Example 2, see appendix Figure 6-7 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.

[0029] 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.

[0030] Example 3, see appendix Figure 9-1013. 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.

[0031] 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.

[0032] 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.

[0033] Example 4, see appendix Figure 14-19 The wire feeding mechanism 05 in one 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. Several mounting holes 52 are evenly distributed on the edge of the supporting plate 51. Fastening bolts 521 are provided in the mounting holes 52. The supporting plate 51 is fixed to the bearing plate by the fastening 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. After the two are connected to each other, their end faces are flush. One end of the tube shaft 6 is integrally connected to a fixed end plate 61, and the other end is connected to 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 mounted 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 within the fixed frame by the limiting plate 53.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.
