Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a synchronous drive device for seedling weaving and laying. Background Technology

[0002] Crops such as sweet potatoes are mainly planted using the raised bed method. Taking sweet potatoes as an example, before planting, select well-drained, fertile, and loose land for deep plowing and harrowing to break up and loosen the soil; then raise beds, which facilitates drainage and the growth of sweet potato tubers; then select sweet potato seedlings that are free from diseases and pests, have strong stems and vines, and short internodes; insert the sweet potato seedlings into the middle of the raised bed, with the spacing between plants depending on the variety and soil fertility; after planting, water them promptly to improve the survival rate.

[0003] Currently, crops grown using soilless transplanting are typically planted manually or using semi-automatic transplanters. Large-scale manual planting requires significant labor costs, and the precision in controlling the planting depth and spacing of seedlings is poor. Semi-automatic transplanters require manual assistance in delivering seedlings, necessitating cooperation between the driver and the personnel delivering the seedlings. Furthermore, to ensure the seedlings are planted to the required standard, the transplanter's speed is usually slow. While this reduces the labor intensity for workers, it offers limited improvement in planting efficiency. Considering the equipment cost and subsequent maintenance costs of semi-automatic transplanters, they do not offer a significant advantage over manual seedling planting.

[0004] Therefore, it is necessary to improve the planting method of sweet potatoes, adopt an integrated weaving and laying method for high-efficiency planting, and design corresponding special weaving equipment for seedling weaving. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a synchronous drive device for seedling weaving and laying.

A rotating shaft is coaxially fixed to one end face of the turntable. The rotating shaft is coaxially rotatably fitted inside the round tube base. A braided bracket is provided on the other end face. A drive mechanism connected to the rotating shaft is provided inside the support. The guiding mechanism includes a tripod body, a hollow shaft, a support wheel, and a pressure wheel fixed on a turntable. Both ends of one side of the tripod body have circular seats. The circular seats have radially arranged docking holes on their circumferential surfaces. The end sides of the tripod body have cylindrical protrusions that are fixedly fitted into the docking holes. The hollow shaft is rotatably fitted between the through holes in the centers of the two circular seats. These through holes are coaxially arranged with the circular seats. The hollow shaft passes vertically through the turntable and faces the braiding bracket. The support wheel is coaxially fixed on the hollow shaft between the two circular seats. The middle of the tripod body has a cable routing hole facing the support wheel; this cable routing hole is a vertically arranged elongated oval hole. The pressure wheel is rotatably installed between the edges of the inner surfaces of the two circular seats and faces the support wheel. A cable routing gap is left between the rolling surfaces of the pressure wheel and the rolling surfaces of the support wheel; the size of this cable routing gap is slightly smaller than the diameter of the braided rope. A driven gear is mounted on the hollow shaft. The driven gear is fixedly connected to the hollow shaft via a key and a keyway. A fixed gear that meshes with the driven gear is fixedly mounted at the end of the round tube seat.

[0007] Preferably, the braided bracket center rod and the synchronizing lever have a bushing in the middle of the synchronizing lever, the bushing is fixedly fitted on the center rod, the center rod is coaxially fixedly connected to the other end face of the turntable, and a plurality of threading holes are evenly provided on the synchronizing lever.

[0008] Preferably, an I-beam wheel is fixedly installed in the middle of the hollow shaft, and a support wheel is fixedly installed between the two limiting wheel bodies of the I-beam wheel. A chamfer is provided on the edge of the limiting wheel body, and an annular groove is formed between the outer surfaces of the two limiting wheel bodies and the support wheel. The width of the pressure wheel is the same as the width of the annular groove.

[0009] Preferably, the end of the tripod body is provided with an arc-shaped boss, the outer side of the arc-shaped boss is provided with an arc-shaped guide groove, the bottom of the arc-shaped guide groove is an arc-shaped bottom, one end of the arc-shaped guide groove corresponds to the port of the hollow shaft, and the other end corresponds to the wiring hole inside the tripod body. The middle part of the arc-shaped boss is provided with a U-shaped sleeve that fits on the outside of the arc-shaped guide groove, and at least two U-shaped sleeves are arranged side by side.

[0010] Preferably, both the support wheel and the pressure wheel are gears, with the two gears having the same width, and the diameter of the pressure wheel being larger than that of the support wheel.

[0011] Preferably, the support wheel is a flexible rubber gear.

[0012] 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 cross-section of the shaft hole is oblong, and the length direction of the oblong shaft hole is consistent with the radial direction of the circular base. The wheel axles on both sides of the pressure roller are fitted into the two shaft holes. The shaft hole is a blind hole. A radial hole is provided on the circumferential side of the circular base, which extends to the shaft hole. The spring is fitted into the radial hole, and the size of the spring matches the size of the radial hole to prevent it from shaking in the radial hole. The limiting stud is threaded to the upper end of the radial hole and clamps the spring.

[0013] Preferably, the end face of the limiting stud is provided with a guide shaft, which is an optical shaft. The size of the guide shaft is smaller than the inner diameter of the spring, and the guide shaft extends into the spring.

[0016] The beneficial technical effects of this invention are: (1) The present invention drives the turntable to rotate by rotating the drive shaft inside the round tube seat. The braiding bracket and guide mechanism installed on the turntable rotate accordingly. At the same time, the driven gear on the guide mechanism meshes and rotates along the circumference of the fixed gear, providing guide power for the guide mechanism. The braided rope enters the braiding bracket for braiding under the auxiliary drive of the guide power. Only one power source is needed to realize the synchronous drive of seedling braiding and braided rope release guide, which is conducive to the miniaturization and lightweight design requirements of the braiding device, reduces equipment cost, and does not require multiple power sources to cooperate. It can improve the coordination accuracy of seedling release and braiding, and improve the braiding quality of seedlings.

[0017] (2) The guiding mechanism winds the braided rope around the support wheel. The braided rope is pressed by a pressure wheel 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, which will generate a pulling force on the braided rope. 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.

[0020] Example 1, see appendix Figure 1-7A synchronous drive device for seedling weaving and laying includes a circular tube seat 2, a turntable 3, and a guide mechanism 4. The circular tube seat 2 is fixed to one end of a support 1, and a flange is provided at the end of the circular tube seat 2. The circular tube seat 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 fixedly connected to one end face of the turntable 3. Second bearings 22 are provided at both ends of the circular tube seat 2. The rotating shaft 31 is coaxially rotated and mounted on the circular tube seat 2 through the second bearings 22. Inside, a braiding bracket is provided on the other end face. The braiding bracket, turntable 3, and rotating shaft 31 are fixedly connected as a whole and rotate synchronously. A drive mechanism connected to the rotating shaft 31 is provided inside the support 1. The drive mechanism includes a motor 11, a driving pulley 12, a driven pulley 13, and a belt 14. The motor 11 is located at the end of the support 1. The driving 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 driving pulley 12 and the driven pulley 13. The motor 11 drives the driving pulley 12 to rotate. The driving pulley 12 drives the driven pulley 13 to rotate through the belt 14. The driven pulley 13 drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the turntable 3 to rotate at the end of the circular tube seat 2.

[0021] The guiding mechanism 4 includes a tripod body 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 tripod body 41 is mounted on the fixed shaft 50 and locked in place by a nut. Two circular seats 46 are provided at both ends of one side of the tripod body 41. The hollow shaft 42 is rotatably fitted between the through holes in the centers of the two circular seats 46. Bearings are installed in the through holes at both ends of the circular seats 46, and the hollow shaft 42 is rotatably fitted between the two bearings. 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 faces the braided bracket. The support wheel 43 is coaxially fixed on the hollow shaft 42 between the two circular seats 46. The center of the support wheel 43 has a cable hole 411 facing the support wheel 43. The braided rope 48 passes through the cable hole 411 and is wrapped around the outer side of the support wheel 43. The pressure wheel 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 hole gap is left between the rolling surface of the pressure wheel 44 and the rolling surface of the support wheel 43. The size of the cable hole gap is slightly smaller than the size of the braided rope 48, so that the braided rope 48 is in a compressed and deformed state and passes through the cable hole gap. At least two pressure wheels 44 are evenly distributed along the circumference of the circular seats 46. Multiple pressure wheels 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 increase the rolling friction force of the braided rope 48 on the support wheel 43.

[0022] A hollow shaft 42 extends out of a round hole on a turntable 3. A bearing 36 with a seat is provided between the hollow shaft 42 and the round hole. A driven gear 47 is mounted on the hollow shaft 42. The driven gear 47 drives the hollow shaft 42 to rotate between the two round seats 46. The hollow shaft 42 drives the support wheel 43 to rotate synchronously. A fixed gear 21 that meshes with the driven gear 47 is fixedly installed at the end of the round tube seat 2.

[0023] The 48-inch braided rope is made of paper. The paper rope decomposes quickly after being placed in the soil with the seedlings, thus avoiding any impact on the normal growth of the seedlings.

[0024] A helical reel 421 is fixedly mounted in the middle of the hollow shaft 42, and a support wheel 43 is fixedly mounted between the two limiting wheels of the helical reel 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 reel 421, forming a modular component assembly structure, which facilitates the processing and manufacturing of components 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 412 is provided with an arc-shaped guide groove 413. One end of the arc-shaped guide groove 413 corresponds to the end 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 against 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 wheel 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 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.

[0026] A U-shaped sleeve 414 is provided in the middle of the arc-shaped boss 412 and 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 and ensure the high-efficiency and stable operation of the guide mechanism 4.

[0027] The braided bracket has a central rod 32 and a synchronous lever 33. The synchronous lever has a bushing 34 in the middle, which is fixedly fitted onto the central rod 32. The central rod is coaxially fixedly connected to the other end face of the turntable 3. Several wire holes 35 are evenly provided on the synchronous lever 33.

[0028] The working process and principle of this embodiment are as follows: ① The starting motor 11 drives the driving pulley 12 to rotate, and the driving pulley 12 drives the driven pulley 13 to rotate through the belt 14. The driven pulley 13 drives the rotating shaft 31 to rotate inside the round tube seat 2; ② The rotating shaft 31 drives the turntable 3 to rotate synchronously, and the guide mechanism 4 fixed on the turntable 3 rotates accordingly. The driven gear 47 in the guide mechanism 4 meshes and rotates along the circumference of the fixed gear 21, driving the hollow shaft 42 to rotate relative to the two round seats 46; ③ The hollow shaft 42 drives the I-beam wheel 421 and the support wheel 43 to rotate. When the support wheel rotates, the pressure wheel 44 rotates accordingly to weave... Rope 48 is pressed against the surface of support wheel 43, and the rolling friction between the two drives the braided rope 48 to rotate with support wheel 43; ④ The braided rope 48 generates pulling force, continuously entering between pressure wheel 44 and support wheel 43 from the thread hole 411, and is then conveyed out from between pressure wheel 44 and support wheel 43 into 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 be led out from the hollow shaft 42 through the thread hole 35 on the braiding bracket; ⑥ The braiding bracket rotates with turntable 3, carrying the braided rope 48 to perform seedling weaving operations.

[0029] Example 2, see appendix Figure 5-6 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 will be bent and deformed by the pressure of the gears and pressed into the tooth grooves between the teeth, thereby greatly increasing the friction of the braided rope 48 between the support wheel 43 and the pressure wheel 44 and improving the pulling and guiding power of the braided rope 48.

[0030] 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 48 has sufficient strength to weave seedlings. 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 of the braided rope 48 between the support wheel 43 and the pressure wheel 44.

[0031] Example 3, see appendix Figure 8-912. 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, a spring 452 and a limiting stud 451 provided on the inner side edge of the circular seat 46. The cross-section of the shaft hole 462 is oblong. The wheel axles 441 on both sides of the pressure roller 44 are matched and 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 against the outer side of the wheel axle 441.

[0032] 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 pressure.

[0033] 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.
