Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more particularly to a seedling weaving rope guiding mechanism. Background Technology

[0002] Tomatoes, cucumbers, and sweet potatoes are typically grown using soilless transplanting. This method preserves the seedlings' root structure, eliminating the need to shake off the soil during transplanting and minimizing root damage. The recovery period can be shortened by more than 50%, compared to 7-10 days for traditional soil-grown seedlings, while soilless transplanting only takes 3-5 days. Furthermore, it avoids soil-borne diseases such as damping-off and root-knot nematodes, making it particularly suitable for large-scale continuous cropping fields.

[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 seedling weaving equipment. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a seedling weaving rope guiding mechanism.

[0006] The technical solution of the present invention is as follows: a seedling weaving rope guiding mechanism, comprising a triangular frame, a hollow shaft, a support wheel, and a pressure wheel; both ends of one side of the triangular frame are provided with circular seats, and the circumferential side of the circular seats is provided with a connecting hole along the radial direction; the end side of the triangular frame is provided with a cylindrical protrusion, which is fixedly fitted into the connecting hole; the center of the circular seat is provided with a through hole, which is coaxially arranged with the circular seat; the hollow shaft is rotatably fitted between the two through holes; the support wheel is coaxially fixedly installed on the hollow shaft between the two circular seats; the middle part of the triangular frame is provided with a wire routing hole facing the support wheel, which is a vertically arranged elongated hole; the pressure wheel is rotatably installed between the edges of the inner sides of the two circular seats and is arranged facing the support wheel; a wire routing gap is left between the rolling surface of the pressure wheel and the rolling surface of the support wheel, the size of which is slightly smaller than the diameter of the weaving rope; a drive wheel is installed at one end of the hollow shaft, and the drive wheel is fixedly connected to the hollow shaft through a key and a keyway.

[0007] 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.

[0008] 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.

[0009] Preferably, the center of the arc-shaped boss is provided with a U-shaped sleeve that fits over 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 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. The wheel axles on both sides of the pressure roller are fitted into the two shaft holes. A radial hole extending through the shaft hole is provided on the circumferential side of the circular base. The spring is fitted into the radial hole, and the size of the spring matches the size of the radial hole to prevent wobbling within 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.

[0014] Preferably, at least two pressure rollers are evenly distributed along the circumference of the circular base.

[0015] The beneficial technical effects of this invention are: This invention involves winding a braided rope around a support wheel. A pressure roller is placed on the outside of the support wheel to compress the rope. When the support wheel rotates, the friction generated by the compression causes the rope to rotate with the wheel, creating a pulling force. The rope, carrying this pulling force, is fed into an arc-shaped guide groove. This groove provides arc-shaped support and guidance, allowing the rope to smoothly enter the hollow shaft and be led out for subsequent weaving operations. This design eliminates the need to apply significant tension to the rope for stable output during seedling weaving, avoiding damage to the rope and ensuring the quality of seedling weaving while improving weaving efficiency.

[0018] Example 1, see appendix Figure 1-36-7, a seedling weaving rope guiding mechanism, comprising a triangular frame 11, a hollow shaft 12, a support wheel 13, and a pressure wheel 14; each end of one side of the triangular frame 11 is provided with a circular seat 16, the center of which has a through hole, and bearings 19 are installed in the through holes at both ends of the circular seat 16; the hollow shaft 12 is rotatably fitted between the two bearings 19, or the hollow shaft 12 can be directly rotatably fitted between the two through holes; the support wheel 13 is coaxially fixedly installed on the hollow shaft 12 between the two circular seats 16; the middle of the triangular frame 11 is provided with a cable routing hole 111 facing the support wheel 13, for weaving... Rope 18 passes through the cable hole 111 and is wrapped around the outer side of the support wheel 13; pressure wheel 14 is rotatably mounted between the edges of the inner sides of the two circular seats 16 and is arranged directly opposite the support wheel 13. A cable routing gap is left between the rolling surface of the pressure wheel 14 and the rolling surface of the support wheel 13. The size of the cable routing gap is slightly smaller than the size of the braided rope 18, so that the braided rope 18 is in a compressed and deformed state and passes through the cable routing gap; a drive wheel 17 is installed at one end of the hollow shaft 12, which drives the hollow shaft 12 to rotate between the two circular seats 16, and the hollow shaft 12 drives the support wheel 13 to rotate synchronously.

[0019] The woven rope 18 is made of paper rope. After the paper rope is put into the soil with the seedlings, it can decompose quickly and avoid affecting the normal growth of the seedlings.

[0020] At least two pressure rollers 14 are evenly distributed along the circumference of the circular base 16. Multiple pressure rollers 14 are arranged in the circumferential direction of the support roller 13 to increase the pressure area of ​​the braided rope 18 on the support roller 13 and improve the rolling friction force of the braided rope 18 on the support roller 13.

[0021] A helical spool 121 is fixedly mounted in the middle of the hollow shaft 12, and a support wheel 13 is fixedly mounted between the two limiting wheels of the helical spool 121. An annular groove 122 is formed between the two limiting wheels and the outer surface of the support wheel 13. The support wheel 13 is connected to the hollow shaft 12 through the helical spool 121, forming a modular component assembly structure, which facilitates the processing and manufacturing of components and reduces costs. The annular groove 122 is used to provide a limit for the braided rope 18, restricting it between the support wheel 13 and the pressure wheel 14, and preventing the braided rope 18 from slipping off between the support wheel 13 and the pressure wheel 14.

[0022] The end of the tripod body 11 is provided with an arc-shaped boss 112, and the outer side of the arc-shaped boss 112 is provided with an arc-shaped guide groove 113. One end of the arc-shaped guide groove 113 corresponds to the port of the hollow shaft 12, and the other end corresponds to the cable routing hole 111 inside the tripod body 11. The braided rope 18 is wound around the support wheel 13 and pressed tightly to the outer side of the support wheel 13 by the pressure wheel 14. After the support wheel 13 rotates, the braided rope 18 will rotate with the support wheel under the rolling friction of the pressure wheel 14 and the support wheel 13. The braided rope 18 generates a certain pulling force, and then the braided rope 18 is sent out into the arc-shaped guide groove 113. The arc-shaped guide groove 113 provides arc-shaped guiding support for the braided rope 18, so that it can smoothly enter the hollow shaft 12 after adjusting its direction.

[0023] The arc-shaped boss 112 has a U-shaped sleeve 114 that fits around the arc-shaped guide groove 113 in the middle. The U-shaped sleeve 114 forms a limiting protection structure on the outside of the arc-shaped guide groove 113 to prevent the braided rope 18 from slipping out of the arc-shaped guide groove 113 and ensure the high-efficiency and stable operation of the guiding mechanism.

[0024] The working process and principle of this embodiment are as follows: ① The hollow shaft 12 is driven to rotate between the two circular seats 16 by the drive wheel 17, and the hollow shaft 12 drives the I-beam wheel 121 and the support wheel 13 to rotate synchronously; ② The braided rope 18 rotates with the support wheel 13 under the rolling friction of the pressure wheel 14 and the support wheel 13, so that the braided rope 18 generates pulling force; ③ The braided rope 18 continuously enters between the pressure wheel 14 and the support wheel 13 from the wire hole 111, and is conveyed out from between the pressure wheel 14 and the support wheel 13 into the arc-shaped guide groove 113; ④ The arc-shaped guide groove 113 provides arc-shaped support and guidance for the braided rope 18, so that it can smoothly enter the hollow shaft 12 after adjusting its direction, and be led out from the hollow shaft 12 for subsequent seedling weaving operations.

[0025] Example 2, see appendix Figure 1-2 This embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that the support wheel 13 and the pressure wheel 14 are both gears. The braided rope 18 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 18 between the support wheel 13 and the pressure wheel 14 and improving the pulling and guiding power of the braided rope 18.

[0026] Furthermore, in this embodiment, the support wheel 13 is set as an elastic rubber gear. After being pressed, the rubber gear will produce a certain elastic deformation, which avoids the meshing force between the gears from damaging the braided rope 18 and ensures that the braided rope 18 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 18, further improving the friction of the braided rope 18 between the support wheel 13 and the pressure wheel 14.

[0027] Example 3, see appendix Figure 4-5 8. 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 14 and the circular seat 16. The auxiliary pressing mechanism includes a shaft hole 162 provided on the inner side edge of the circular seat 16, a spring 152, and a limiting stud 151. The cross-section of the shaft hole 162 is oblong. The wheel axles 141 on both sides of the pressure roller 14 are fitted into the two shaft holes 162. The wheel axles 141 of the pressure roller 14 have a radial sliding allowance in the shaft hole 162. A radial hole 161 is provided on the circumferential side of the circular seat 16, which extends to the shaft hole 162. The spring 152 is fitted into the radial hole 161. The limiting stud 151 is threaded to the upper port of the radial hole 161 and presses the spring 152. The limiting stud 151 presses the spring 152 into the radial hole 161, thereby pressing the spring 152 against the outer side of the wheel axle 141.

[0028] The end face of the limiting stud 151 is provided with a guide shaft 153. The guide shaft 153 extends into the inside of the spring 152. The guide shaft 153 provides guidance for the spring 152, preventing the spring 152 from bending in the radial hole 161 and ensuring that it has stable and sufficient elastic pressure.

[0029] The principle and function of the auxiliary pressing mechanism in this embodiment are as follows: During the rotation and movement of the braided rope 18 between the support wheel 13 and the pressure wheel 14, the spring 152 provides pressure to the wheel axle 141 of the pressure wheel 14, so that the wheel axle 141 has a certain elastic movement margin in the shaft hole 162 with an elongated cross-section. This allows the pressure wheel 14 to provide elastic pressure to the braided rope 18, enabling it to rise and fall with the fluctuation of the tension on the braided rope 18 and the irregular side structure of the braided rope 18, providing dynamic pressing force to the braided rope 18 and avoiding excessive rolling pressure of the pressure wheel 14 from damaging the braided rope 18.
