[0056] This utility model is as follows Figures 1-15 As shown, the friction hook tension biaser includes a suspension part 11 and a load-bearing assembly.
[0057] The suspension part 11 is used to suspend on the load-bearing body 2; the load-bearing body is a load-bearing mechanism provided by the greenhouse or field support, specifically iron wire, iron chain, steel wire, steel pipe, etc.; in application, for example, steel wire is used to connect across the greenhouse.
[0058] In application, the suspension unit can be directly connected to the load-bearing body, or indirectly connected via an additional hook.
[0059] The load-bearing assembly is connected to the suspension part 11, and the load-bearing assembly includes a friction rod 12 and a support part 13.
[0060] The friction rod 12 is used to wind the annular rope loop 3.
[0061] The supporting part 13 is used to support the annular rope loop 3.
[0062] In operation, this utility model includes a suspension part and a load-bearing component. The suspension part is suspended on the load-bearing body; the support part in the load-bearing component is used to support the load; the friction rod unfolds the wound rope loop at an appropriate angle (to avoid knotting), and through winding and friction, the small tension on the non-load-bearing side is increased to a level that matches the load.
[0063] The friction hook tension biasing device of this utility model is easy to process, low in cost, easy to operate, and convenient for repeated use and continuous production.
[0064] The method of using the friction hook tension offset device is as follows: wrap the rope around the friction rod an appropriate number of times, pick up the end of the rope near the support part, and wrap it into the support part.
[0065] The friction hook tension offset device is simple and convenient to use, has a stable structure, can prevent rope loops from tangling, is reliable, and is easy to manufacture.
[0066] like Figure 1 , 4 As shown in Figures 7 and 8, the suspension part 11 is connected between the friction rod 12 and the support part 13.
[0067] Depending on the processing requirements, the suspension part can be connected to both the friction rod and the support part.
[0068] like Figure 10 , 13 As shown, the suspension part 11, the support part 12 and the friction rod 13 are connected in sequence.
[0069] The suspension part, support part and friction rod can be connected and set in sequence according to the processing requirements.
[0070] It also includes an anti-detachment part 14, which is connected to the outer end of the friction rod 13;
[0071] The anti-detachment part is used to limit the rope loop on the friction rod.
[0072] The anti-derailment component is used to stabilize the position of the rope loop and prevent the rope loop from detaching from the system and causing failure.
[0073] In applications, the anti-slip part can be set in the shape of a hook (semi-enclosed) or a ring (enclosed). Semi-enclosed parts also include baffles, U-shapes, etc.
[0074] The suspension part 11 has a closed or semi-closed structure.
[0075] In actual production, the friction hook tension offset device will be adjusted according to the usage requirements and production methods. The suspension part will appear in the form of a hook (semi-enclosed) or a ring (enclosed). The semi-enclosed design makes it convenient to disassemble and assemble the suspension part, and it can also move freely on the load-bearing body.
[0076] The supporting part 13 has a closed or semi-closed structure.
[0077] In actual production, the friction hook tension offset device will be adjusted according to the usage requirements and production methods. The support part will appear in the form of a hook (semi-enclosed) or a ring (enclosed); the semi-enclosed design makes it convenient to disassemble and assemble the rope loop.
[0078] The support section is designed to be closed, which facilitates the passage of the rope loop and provides greater support. At the same time, it can prevent the rope loop from coming out of the support section.
[0079] The cross-section of the friction rod 12 is circular or polygonal.
[0080] The shape of the friction rod can be customized to meet specific needs, including polygonal shapes such as chamfered rectangles or squares, as well as hexagonal shapes. The friction rod is used to wind the rope loop, and the resulting friction amplifies the tension on one side.
[0081] The ring-type continuous vine dropping system includes a friction hook tension biaser 1, a ring rope loop 3, and a tensioner 4.
[0082] One end of the upper part of the rope loop 3 is wrapped around the friction rod 12, and the other end passes through and is supported in the support part 13;
[0083] The vine 6 is connected to the rope loop 3 below the support side via a vine fastener 5. The function of the vine fastener is to fix the plant vine to the rope loop, including but not limited to clips, hooks, knots or other mechanical structures that serve the same purpose.
[0084] The tensioner 4 is connected to the bottom of the rope loop 3. The tensioner provides initial tension to the friction rod and can also be used to limit the left and right swing of the rope loop.
[0085] In use, the friction hook tension offset device is hung on a load-bearing body, and the rope loop is wrapped around the friction hook tension offset device. The plant (i.e., the vine) is fixed to the load-bearing side of the rope loop by the vine fixer. When the plant grows taller, the vine fixer on the lower side of the rope loop is removed, the top of the plant is re-fixed, and the non-load-bearing side of the rope loop is gently lifted upwards to release the restriction of the friction hook tension offset device, allowing the vine to fall and complete the vine lowering operation.
[0086] The vine-dropping system of this invention allows for the recycling of ropes, so that crop growth is not limited by the length of the vine-dropping ropes; it facilitates continuous production, avoids the need to replace the vine-dropping ropes every season, and significantly reduces maintenance work.
[0087] This invention addresses the issue of uneven tension on both sides of the rope loop by incorporating a load-bearing component (i.e., a friction rod and a support part) and a tensioner, thereby enabling the rope loop to be fixed on one side of the plant and the vines to be lowered while maintaining a tension bias.
[0088] The tensioner 4 is a counterweight;
[0089] Alternatively, the tensioner may include a spring 8 and a ground anchor 9, the ground anchor being used to fix it to the ground, with one end of the spring connected to a rope loop and the other end connected to the ground anchor, such as... Figure 18 As shown.
[0090] Tensioners can be weights, springs, ropes, or other mechanical structures that can serve the same purpose.
[0091] In actual use, an auxiliary friction hook tension bias device 10 can also be set, which is located at the bottom of the rope loop;
[0092] The auxiliary friction hook tension biasing device has the same structure as the friction hook tension biasing device, but specifically, the auxiliary friction hook tension biasing device is selected in the form where the suspension part is connected between the friction rod and the support part.
[0093] Thus, as Figure 19 As shown, the counterweight can be connected to the suspension part of the auxiliary friction hook force offset device;
[0094] Or such asFigure 20 As shown, the upper end of the spring is connected to the suspension part of the auxiliary friction hook tension bias device, and the lower end is connected to the ground anchor.
[0095] By using an auxiliary friction hook tension biaser in conjunction with a tensioner, the utilization efficiency of the tensioner is improved, and the ineffective load on the greenhouse structure is reduced.
[0096] like Figure 17 As shown, it also includes an extension rope 7, and the counterweight is connected to the rope loop 3 via the extension rope 7.
[0097] Extension ropes can facilitate operation and help crops with long growth cycles and tall stature, such as tomatoes and melons, to mature.
[0098] like Figure 16 As shown, this utility model achieves the fixation of the rope loop suspending the plant on one side and the vine dropping operation through the combined action of the friction hook tension biaser and the tensioner.
[0099] in,
[0100] f: Frictional force generated by the rope loop on the friction rod; W: Tension force exerted by the plant on the rope; F: Initial tension force applied to the rope by the tensioner; F / 2: Tension force borne by the rope on one side;
[0101] The following conditions must be met: W + F / 2 ≤ F / 2 + f. The friction force can be calculated based on Euler's twisted rope equation, which depends on the number of turns and the coefficient of friction, etc.
[0102] This utility model has the following advantages:
[0103] The friction hook pull biaser can easily lift the plant and keep it growing upwards. The rope loop will not get tangled with the plant. All parts are reusable. The vine dropping operation is simple, fast and smooth.
[0104] The rope loop design allows for precise control of vine drop, ensuring flexibility and reliability.
[0105] When clearing straw, simply open a few vine clamps to separate the straw, making it easy to clear and beneficial for returning it to the field.
[0106] This system has a simple and reliable structure, low production cost, quick installation, and is easy to use.
