[0050] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0051] Example 1:

[0052] like Figures 1-3 The traction mechanism shown includes:

[0053] The screw jack 1 has a first screw 101 on which a first nut 102 is rotatably fitted. One end of the first screw 101 is connected to a first motor 103. When the first motor starts, the first screw rotates accordingly, converting the rotational motion of the first screw into the linear motion of the first nut. In this embodiment, the screw jack is mounted on a first frame 104, which is erected along the length of the first screw. Both ends of the first screw are rotatably mounted on the first frame via bearings. The first motor is also mounted on the first frame.

[0054] The inclination workbench 2 is connected to the first nut 102 of the screw rod elevator through the second frame body 201, and has a fixed plate 202 and an inclined plate 203 hingedly connected to each other, with the hinge point located close to one side of the screw rod elevator. The fixed plate 202 is laid flat and fixed on the second frame body 201. A second screw rod 204 is arranged on the upper end surface of the fixed plate 202 in a horizontal direction and rotates in the horizontal direction. The second screw rod 204 is perpendicular to the second screw rod 204 of the screw rod elevator. A second nut 205 is rotatably connected to the second screw rod 204. The second nut 205 is connected to the lower end surface of the inclined plate 203 through a hinge arm 206. The connection points of the hinge arm 206, the second nut 205 and the inclined plate 203 are all movable hinge points. One end of the second screw rod 204 is connected to a second motor 207, and the second motor 207 is installed on the second frame body 201. When the second motor 207 is started, the second screw rod rotates. The rotation of the second screw rod is converted into the linear motion of the first nut, and the inclined plate 203 is lifted through the hinge arm 206. Since the inclined plate 203 and the fixed plate 202 are hingedly connected at one side, the second nut 205 moves back and forth on the second screw rod 204 under the forward and reverse rotation of the second motor 207, so that the inclined plate 203 can change the angle of 0-90° or 90-0° relative to the fixed plate 202. The adjustment angle is controllable.

[0055] The C-shaped inclined ring 3 is laid flat and fixed on the inclined plate 203 of the inclination workbench, so that the C-shaped inclined ring can change with the change of the angle of the inclined plate 203. The opening of the C-shaped inclined ring is located away from the inclination workbench, which serves as the entrance and exit of the cowpea vine.

[0056] The C-shaped limiting ring 4 is rotatably arranged on the C-shaped inclined ring through a plurality of universal ball bearings 401 arranged on the lower end surface of the C-shaped limiting ring. The center point of the C-shaped limiting ring 4 coincides with the center point of the C-shaped inclined ring 3. The inner diameter of the C-shaped limiting ring 4 is smaller than the inner diameter of the C-shaped inclined ring 3, so as to facilitate the gathering of cowpea seedlings through the inner circle of the C-shaped inclined ring 3. An arc-shaped tooth 402 is arranged along the outer edge of the C-shaped limiting ring 4. The arc-shaped tooth 402 is engaged with a plurality of limiting gears 403 arranged on the C-shaped inclined ring. At least one limiting gear 403 is connected and driven to rotate by a third motor 404, and the third motor 404 is installed on the C-shaped inclined ring 3.

[0057] The limiting small ring assembly 5 includes a limiting frame 501 installed on the central upper end face of the C-shaped limiting large ring 4. One side of the limiting frame 501 has a mounting port, which faces the direction of the opening of the C-shaped inclined ring 3. The limiting frame 501 has two incomplete gears 502 meshing with each other. Each incomplete gear 502 extends an arc-shaped rocker arm 503 from the circumference. The two arc-shaped rocker arms 503 extend from the mounting port and embrace each other. They open and close with the rotation of the incomplete gears 502. At least one incomplete gear 502 is connected and driven to rotate by the fourth motor 504 installed on the limiting frame 501. When the fourth motor 504 is started, the two arc-shaped rocker arms 503 are retracted to further hold the cowpea seedlings.

[0058] When the traction mechanism is working, it drives the first nut to move linearly along the screw rod by driving the first screw rod to rotate through the first motor. This mechanism is vertically arranged to adjust the height of the inclined workbench connected to the first nut. The inclined workbench drives the inclined plate to adjust the angle between 0° and 90° or between 90° and 0° by driving the second screw rod to rotate through the second motor. This design allows the C-shaped limiting large ring and the limiting small ring assembly to obtain the best traction angle for the cowpea vine and quickly adapt to cowpea vines at different positions. The C-shaped inclined ring changes with the angle of the inclined plate, providing an entrance and an exit for the cowpea vine, facilitating the entry and exit of the cowpea vine, and also providing stable support for subsequent bundling. The C-shaped limiting large ring is rotatably arranged on the inclined ring through universal ball bearings, and the inner ring diameter is smaller than the inclined ring, which is used to gather cowpea seedlings. The cooperation of the arc-shaped teeth and the limiting gear ensures the stability and positioning accuracy of the cowpea seedlings. The combination of the limiting frame and the two incomplete gears in the limiting small ring assembly, as well as the opening and closing of the arc-shaped rocker arms, are used to further hold the cowpea seedlings during the vine guiding process, ensuring firmness.

[0059] The above design brings the following benefits: the entire mechanism is driven by motors, achieving automatic control, greatly reducing the need for manual operation, and improving production efficiency. By adjusting the inclination and limiting, it can adapt to cowpea vines at different positions in different growth stages. The design of the C-shaped inclined ring and the limiting large ring makes the mechanism more compact in space, suitable for efficient operation in limited space. Through the cooperation of the limiting gear and the arc-shaped teeth, as well as the opening and closing of the rocker arms, the firmness of the vine guiding is ensured.

[0060] Overall, the design of the traction mechanism closely combines the actual needs of agricultural production and the development trend of automation technology, not only improving production efficiency and the stability of vine climbing, but also providing a new solution for agricultural mechanization and automation. It should be noted that in order to improve the degree of automation, the screw lifter can be combined with a mobile device to change position, and can also be combined with an infrared detector group to detect the position of the cowpea seedlings. The controller can control the driving motors in sequence through the set program to realize the vine guiding process.

[0061] Example 2:

[0062] A multi-difference displacement spiral winding and binding device, which includes a binding mechanism in addition to the traction mechanism of Embodiment 1.

[0063] The automatic bundling mechanism includes:

[0064] like Figures 4-6 The housing 6 shown is connected to the C-shaped inclined ring of the traction mechanism;

[0065] The metal wire conveying assembly 7 includes a wire-binding shaft 701 and a friction wheel assembly 702 installed in the housing 6. A winding reel for providing metal wire is rotatably mounted on the wire-binding shaft 701. The winding reel can rotate to extend the metal wire from the wire-binding shaft 701. The friction wheel assembly 702 includes a set of rollers that act together on the winding reel of the metal wire. At least one roller is connected to and driven by a fifth motor 703. The friction of the rollers causes the metal wire to be output. Preferably, the metal wire can be threaded in a limiting track to ensure that the output direction of the metal wire is always consistent.

[0066] The metal tie wire twisting assembly 8 includes a twisting head 801 and a sixth motor 802. The twisting head 801 is Z-shaped and has two centrally symmetrical first twisting ports 803 and second twisting ports 804. The output shaft of the sixth motor 802 is parallel to the initial movement direction of the metal tie wire. The metal tie wire conveying assembly 7 conveys the metal tie wire first through the first twisting port 803 to receive the metal tie wire before bending, and the second twisting port 804 to receive the metal tie wire after bending. When the sixth motor 802 is started, the metal tie wire is tied on the cowpea stalk under the rotation of the first twisting port 803 and the second twisting port 804.

[0067] The metal wire bending assembly 9 includes an F-type connecting rod 901 and a second cylinder 902. The F-type connecting rod 901 comprises a long rod 901a, a main rod 901b, and a short rod 901c connected as one piece. The end of the main rod is hinged to the piston end of the second cylinder 902. Both the short rod 901c and the tail end of the cylinder body of the second cylinder 902 have sliding posts 903. The sliding posts 903 are slidably disposed in L-shaped limiting slides 904 opened on the two side walls of the housing 6. Figure 7The outermost end face of the long rod 901a shown has a groove 905. When the second cylinder 902 is in the initial position, the opening of the groove 905 of the long rod 901a is aligned with the protruding end of the metal tie wire. In the coaxial direction of the main rod 901b and the second cylinder 902, when the second cylinder 902 extends, the short rod 901c and the sliding column 903 at the cylinder tail end of the second cylinder 902 slide in the L-shaped limiting slide 904, so that the axis of the main rod 901b and the second cylinder 902 forms a 90° tilt angle. During the process of forming the 90° tilt angle, the groove 905 pushes the protruding end of the metal tie wire to bend. This process forms an outer periphery for the metal tie wire to bind the vines that need to be tightened. The bent metal tie wire is located at the opening of the second twisting port 804. Preferably, in order to give the metal tie wire enough extension space, the long rod 901a is bent along the arc in the direction close to the short rod 901c.

[0068] Metal wire shearing assembly 10, such as Figure 5 and Figure 6 The diagram shows scissors 1001 and a first cylinder 1002 that drives scissors 1001 to open and close. Scissors 1001 is located beside friction wheel assembly 702. The metal binding wire output from friction wheel assembly 702 passes through the two cutting blades of scissors 1001. One end of scissors 1001 is hinged to the piston end of the first cylinder 1002, and the other end of scissors 1001 is hinged to the fixed end of the first cylinder. When the first cylinder is activated, it drives scissors 1001 to open and close, which is used to pass through and cut the metal binding wire. Note that the cutting operation is performed before the sixth motor 802 is started and the metal binding wire is tied by the rotation of the first torsion port 803 and the second torsion port 804.

[0069] When the binding mechanism is working, the metal wire conveying assembly conveys the metal wire from the winding reel through the wire shaft and friction wheel set. The fifth motor drives the roller to rotate, causing the wire to pass through the friction wheel set. The metal wire first passes through the first torsion opening of the metal wire bending assembly and continues to be conveyed forward to the groove. Driven by the second cylinder, the main rod forms a 90° angle with the second cylinder. The groove pushes the protruding end of the metal wire to bend, forming the outer periphery. The bent metal wire is located at the opening of the second torsion opening. The scissors of the metal wire cutting assembly are activated. The first cylinder drives the scissors to open and close, cutting the metal wire before binding. Then, driven by the sixth motor, the wire is bound to the cowpea stalk through the rotation of the first and second torsion openings.

[0070] The advantages of this binding mechanism design are:

[0071] The metal wire bending assembly can easily achieve the bending of the metal wire through the design of the F-shaped connecting rod and the second cylinder, which simplifies the operation process and reduces the operation difficulty, so that even inexperienced personnel can quickly master the use method. Since the F-shaped connecting rod and the second cylinder can quickly achieve the bending of the metal wire at a 90° inclination angle, the bundling process is more efficient, and the bundling task can be completed faster. Precise bending control means that the wire can be bent at a consistent angle and force, thereby improving the overall quality of the bundling. The design of the metal wire bending assembly allows it to adapt to different sizes of vines and maintain good working performance.

[0072] The metal wire twisting assembly ensures that the angle and force of the metal wire remain consistent when bundling the cowpea stem through the design of the Z-shaped twisting head, which is very important for improving the overall quality of the bundling and the growth support of the cowpea. By precisely controlling the twisting angle and force of the metal wire, material conservation can be achieved, avoiding excessive use of wire, thereby reducing planting costs. The rapid rotation of the twisting assembly makes the bundling process more rapid, which improves the overall work efficiency, which is particularly important for large-scale planting. The Z-shaped twisting head design makes the metal wire twisting assembly more compact, and the overall metal wire conveying assembly and metal wire shearing assembly are concentrated in one housing, which helps to optimize the overall equipment layout and reduce the floor area.

[0073] In summary, the design of the metal wire bending assembly not only improves the efficiency and quality of the bundling, but also increases the adaptability, which is of great significance for improving the automation level and efficiency of agricultural production. In addition to cowpea, this design can also be applied to other crops that need to be bundled, such as grapes, cucumbers, etc. Through these designs, not only the efficiency and quality of the bundling are improved, but also new solutions are provided for agricultural mechanization and automation, which helps to improve the overall level of agricultural production.

[0074] Example Three:

[0076] The double-coordinate high-load moving mechanism includes:

[0077] As Figure 8The shown scissor structure 11 includes a third frame body 1101 mounted on the automatic moving mechanism push ball bearing 15, the third frame body 1101 is provided with a third screw rod 1102 rotating in the horizontal direction, the third screw rod 1102 is installed on the third frame body 1101 in two groups, the third screw rod 1102 is rotatably connected with the third nut 1103, and one of the hinge points of the scissor structure is connected to the third nut 1103; the third frame body 1101 is a polygonal frame structure, and an installation space for placing the controller can be formed in the frame, the controller is connected and controls the orderly work of each part, and the related control principle and control process depend on the electrical control principle in the prior art;

[0079] The screw connecting piece 13 is fixedly connected to the scissor connecting piece 12 and connected with the first frame body 104 of the screw rod elevator 1.

[0080] The double-coordinate high-load moving mechanism can move in the horizontal direction through the rotation of the scissor structure, so that the binding mechanism can reach different positions for work. The rotation of the scissor structure is controlled by the third motor to realize precise positioning.
