Description

Technical Field

[0001] This application relates to the field of agricultural technology, and in particular to a modular, retractable crop support frame. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary sector, and the science that studies agriculture is agronomy. The objects of agricultural labor are living plants and animals, and the products obtained are the plants and animals themselves. Agriculture is a fundamental industry that supports national economic construction and development. Crops are various plants cultivated in agriculture, including two main categories: food crops and cash crops. The saying "Food is the first necessity of man" expresses the relationship between humans and food. A reasonable diet is essential for human health. The growth of crops is inseparable from scientific and technological production techniques. During the cultivation of crops, support frames are needed to support the crop stems.

[0003] However, existing devices are not convenient for adjusting the height of the support, cannot adapt to the support needs of crops at different growth stages and with different plant types, and are not convenient for adjusting the position of the support according to the planting density of crops. In order to solve the above problems, a modular and retractable crop support frame is proposed. Utility Model Content

[0004] The purpose of this application is to provide a modular and retractable crop support frame, which has the advantages of easy height adjustment, adaptability to the support needs of crops at different growth stages and with different plant types, and easy adjustment of the support position according to the planting density of crops.

[0005] This application provides a modular and retractable crop support frame with the following technical solution: A modular and retractable crop support frame includes a fixed tube, a protective shell fixedly connected to the surface of the fixed tube, an adjustment chamber fixedly connected to the surface of the protective shell, a bearing fixedly connected inside the adjustment chamber to allow a first rotating shaft to pass through it, a transmission worm gear fixedly connected to the surface of the first rotating shaft, a bearing fixedly connected to the surface of the adjustment chamber to allow a second rotating shaft to pass through it, a transmission worm wheel fixedly connected to the surface of the second rotating shaft, the transmission worm gear and the transmission worm wheel meshing with each other, a threaded post provided inside the protective shell, and one end of the second rotating shaft... A threaded tube is fitted onto the surface of the threaded tube, and a clamping plate is provided inside the protective shell. One end of the threaded tube is fixedly connected to the clamping plate. A telescopic rod is fixedly connected inside the protective shell. A movable rod passes through the inside of the fixed tube. A support plate is attached to the top of the movable rod. A movable frame is fitted onto the surface of the support plate. A limit groove is fixedly connected to the upper surface of the movable frame. A limit rod passes through the inside of the limit groove. A second spring is fitted onto the surface of the limit rod. A locking block is fixedly connected to the bottom end of the limit rod. A fixing ring is fixedly connected to the lower surface of the movable frame. A traction rope is fixedly connected to the surface of the fixing ring.

[0006] By adopting the above technical solution, with the cooperation of the transmission worm and the transmission worm wheel, the second rotating shaft can drive the threaded tube on the surface of the threaded column to move the clamping plate. With the guiding effect of the telescopic rod, the clamping plate can stably and accurately clamp and fix the movable rod, flexibly adjust the support height of the support plate, adapt to the support needs of crops at different growth stages and with different plant types, and enhance the versatility of the support frame. Simply by using the handle to drive the locking block at the bottom of the limit rod to disengage from the slot on the surface of the support plate, the movable frame can be pushed laterally along the surface of the support plate, making it easy to adjust the position of the movable frame according to the planting density of the crops.

[0007] Preferably, a knob is fixedly connected to one end of the first rotating shaft, and a threaded hole is provided at the top end of the movable rod. There are two sets of threaded holes, and the other set of threaded holes is provided on the surface of the support plate.

[0008] By adopting the above technical solution, the knob at the end of the first rotating shaft provides a convenient operating point for manually adjusting the worm gear transmission. The first rotating shaft can be rotated without the need for additional tools, simplifying the adjustment process of the clamping plate. The two sets of threaded holes on the surface of the movable rod and the support plate further enhance the stability of the connection between the movable rod and the support plate, preventing the support plate from shifting when supporting crops.

[0009] Preferably, a fixing bolt is inserted inside the threaded hole, the movable rod and the support plate are fixedly connected by the fixing bolt, and a counterweight is fixedly connected to the bottom end of the traction rope.

[0010] By adopting the above technical solution, the fixing bolts inserted in the threaded holes can firmly lock the movable rod and the support plate, preventing them from loosening due to external forces such as crop weight and wind during long-term support, thus ensuring the reliability of the support structure. The counterweight at the bottom of the traction rope pulls down the fixing ring by its own weight, which can generate a downward pulling force on the movable frame and the support plate, offsetting part of the upward force of the crop on the support plate, improving the overall anti-tipping ability of the support frame, and is especially suitable for windy planting environments.

[0011] Preferably, a slider is fixedly connected to the surface of the movable rod, and a groove is provided inside the fixed tube. The slider is movably connected inside the groove. There are two sets of sliders and grooves, which are symmetrically arranged inside the fixed tube.

[0012] By adopting the above technical solution, the slider on the surface of the movable rod and the groove inside the fixed tube form a sliding fit, which can strictly limit the movement direction of the movable rod in the fixed tube, and only extend and retract in the vertical direction. This avoids lateral displacement or rotation when the movable rod extends and retracts, ensuring the stability of the movable rod when adjusting its height, thereby ensuring the accuracy of the support plate's support position and preventing crops from falling over due to the offset of the support position.

[0013] Preferably, the surface of the movable rod is provided with anti-slip texture, and an anti-slip pad is fixedly connected inside the clamping plate. The anti-slip pad is made of rubber material.

[0014] By adopting the above technical solution, the anti-slip texture on the surface of the movable rod can increase the friction between the hand and the movable rod, making it easier for operators to manually adjust the height of the movable rod and avoid slipping, thus improving the safety and convenience of operation. The rubber anti-slip pad inside the clamping plate has good elasticity and friction, which can not only increase the contact friction between the clamping plate and the movable rod to prevent the movable rod from slipping, but also buffer the clamping force through the elasticity of the rubber to avoid damaging the movable rod.

[0015] Preferably, the other end of the telescopic rod is fixedly connected to the clamping plate, and a first spring is sleeved on the surface of the telescopic rod. There are two sets of both the telescopic rod and the first spring, which are symmetrically arranged inside the protective shell.

[0016] By adopting the above technical solution, one end of the telescopic rod is fixed to the protective shell and the other end is fixed to the clamping plate, which can guide the movement direction of the clamping plate and prevent the clamping plate from tilting under the push of the threaded tube; the first spring on the surface of the telescopic rod can use its own elasticity to form a buffer for the clamping plate, and when the clamping plate contacts the movable rod, the rebound force of the first spring can ensure the continuous clamping force of the clamping plate on the movable rod, ensuring reliable clamping.

[0017] Preferably, the surface of the support plate is provided with slots, there are multiple sets of slots and they are evenly arranged on the surface of the support plate. The slots and the blocks are matched. One end of the limiting rod is fixedly connected to a handle.

[0018] By adopting the above technical solution, multiple sets of slots evenly arranged on the surface of the support plate can cooperate with the slot blocks to fix the movable frame in multiple positions on the support plate. Operators can flexibly adjust the lateral support position of the movable frame according to the planting density of the crops to adapt to the support needs of different crops. The handle at the end of the limit rod provides a convenient force application point for pulling the limit rod, which facilitates quick control of the separation or engagement of the slot blocks and slots, simplifying the position adjustment process of the movable frame.

[0019] Preferably, a fixing plate is fixedly connected to the bottom end of the fixing tube, and a fixing cone is fixedly connected to the lower surface of the fixing plate. There are multiple fixing cones, which are evenly arranged on the lower surface of the fixing plate.

[0020] By adopting the above technical solution, the fixing plate at the bottom of the fixing pipe can increase the contact area between the support frame and the ground, reduce the pressure of the support frame on the ground, and prevent the support frame from sinking into the soft soil due to its own weight or the weight of the crop; the multiple fixing cones on the lower surface of the fixing plate can penetrate into the ground to form multi-point fixation, significantly enhance the bonding strength between the support frame and the ground, prevent the support frame from tipping over under the action of external forces such as wind and crop pull, and improve the overall stability.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This modular, retractable crop support frame utilizes a transmission worm gear and worm wheel. A second rotating shaft drives a threaded tube on the surface of a threaded column, propelling a clamping plate. Combined with the guiding action of a telescopic rod, the clamping plate smoothly and precisely clamps and fixes the movable rod, allowing for flexible adjustment of the support plate's height to accommodate different growth stages and plant types, thus enhancing the support frame's versatility. Furthermore, by incorporating a limit rod and a second spring, simply moving the lever at the bottom of the limit rod disengages it from the groove on the support plate surface, allowing the movable frame to be pushed laterally along the support plate surface. This facilitates adjustment of the movable frame's position according to crop planting density. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A modular, retractable crop support frame, referring to... Figure 1 , Figure 2 and Figure 3The system includes a fixed tube 1, a protective shell 2 fixedly connected to the surface of the fixed tube 1, an adjusting chamber 3 fixedly connected to the surface of the protective shell 2, a bearing fixedly connected inside the adjusting chamber 3 to allow a first rotating shaft 4 to pass through it, and a transmission worm gear 5 fixedly connected to the surface of the first rotating shaft 4. By setting the transmission worm gear 5 and the transmission worm wheel 7, the second rotating shaft 6 drives the threaded tube 10 on the surface of the threaded column 9 to push the clamping plate 11 to move. Combined with the guiding action of the telescopic rod 13, the clamping plate 11 can stably and accurately clamp and fix the movable rod 15, thereby flexibly adjusting the support height of the support plate 19 to adapt to the support needs of crops at different growth stages and with different plant types, enhancing the versatility of the support frame. The adjusting chamber 3 is fixedly connected to a bearing to allow a second rotating shaft 6 to pass through it, and a transmission worm wheel 7 fixedly connected to the surface of the second rotating shaft 6. The transmission worm gear 5 and the transmission worm wheel 7 mesh with each other. A threaded column 9 is provided inside the protective shell 2, and one end of the second rotating shaft 6 is fixedly connected to the threaded column 9. A threaded tube 10 is fitted onto the surface of the protective shell 2. A clamping plate 11 is provided inside the protective shell 2. One end of the threaded tube 10 is fixedly connected to the clamping plate 11. A telescopic rod 13 is fixedly connected inside the protective shell 2. A movable rod 15 passes through the inside of the fixed tube 1. A support plate 19 is attached to the top of the movable rod 15. A movable frame 21 is fitted onto the surface of the support plate 19. A limit groove 22 is fixedly connected to the upper surface of the movable frame 21. A limit rod 23 passes through the inside of the limit groove 22. A first... With the two springs 24, by setting the limiting rod 23 and the second spring 24, the movable frame 21 can be pushed laterally along the surface of the support plate 19 simply by driving the locking block 25 at the bottom of the limiting rod 23 out of the slot 27 on the surface of the support plate 19 through the handle 26. This makes it easy to adjust the position of the movable frame 21 according to the planting density of the crops. The locking block 25 is fixedly connected to the bottom of the limiting rod 23, and the lower surface of the movable frame 21 is fixedly connected to the fixing ring 28. The surface of the fixing ring 28 is fixedly connected to the traction rope 29.

[0032] Please see Figure 2 , Figure 3 and Figure 4A knob 8 is fixedly connected to one end of the first rotating shaft 4. A threaded hole 18 is provided at the top of the movable rod 15. There are two sets of threaded holes 18, with the other set located on the surface of the support plate 19. The knob 8 at the end of the first rotating shaft 4 provides a convenient operating point for manually adjusting the worm gear transmission, allowing the first rotating shaft 4 to be rotated without additional tools, simplifying the adjustment process of the clamping plate 11. The two sets of threaded holes 18 on the surfaces of the movable rod 15 and the support plate 19 further enhance the stability of the connection between the movable rod 15 and the support plate 19, preventing the support plate 19 from shifting when supporting crops. A fixing bolt 20 passes through the threaded hole 18, and the movable rod 15 and the support plate 19 are fixedly connected by the fixing bolt 20. A counterweight 30 is fixedly connected to the bottom end of the traction rope 29. The fixing bolt 20 passing through the threaded hole 18 can firmly lock the movable rod 15 and the support plate 19, preventing loosening due to crop weight, wind, or other external forces during long-term support. To ensure the reliability of the support structure, the counterweight 30 at the bottom of the traction rope 29 pulls down the fixed ring 28 by its own weight, which can generate a downward pulling force on the movable frame 21 and the support plate 19, offsetting part of the upward force of the crop on the support plate 19, and improving the overall anti-tipping ability of the support frame, especially suitable for windy planting environments. The surface of the movable rod 15 is fixedly connected to the slider 17, and the inside of the fixed tube 1 is provided with a groove 16. The slider 17 is movably connected inside the groove 16. There are two sets of sliders 17 and grooves 16, which are symmetrically arranged inside the fixed tube 1. The slider 17 on the surface of the movable rod 15 and the groove 16 inside the fixed tube 1 form a sliding fit, which can strictly limit the movement direction of the movable rod 15 in the fixed tube 1, and only extend and retract in the vertical direction, avoiding lateral deviation or rotation when the movable rod 15 extends and retracts, ensuring the stability of the movable rod 15 when adjusting the height, thereby ensuring the accuracy of the support position of the support plate 19 and preventing the crop from falling over due to the deviation of the support position.

[0033] Please see Figure 1 , Figure 2 and Figure 3The surface of the movable rod 15 is provided with anti-slip textures, and an anti-slip pad 12 is fixedly connected inside the clamping plate 11. The anti-slip pad 12 is made of rubber. The anti-slip textures on the surface of the movable rod 15 can increase the friction between the hand and the movable rod 15, making it easier for the operator to manually adjust the height of the movable rod 15 and avoid slipping, thus improving the safety and convenience of operation. The rubber anti-slip pad 12 inside the clamping plate 11 has good elasticity and friction, which can not only increase the contact friction between the clamping plate 11 and the movable rod 15 to prevent the movable rod 15 from slipping, but also buffer the clamping force through the elasticity of the rubber to avoid damage to the movable rod 15. The other end of the telescopic rod 13 and The clamping plate 11 is fixedly connected, and the surface of the telescopic rod 13 is fitted with a first spring 14. There are two sets of telescopic rod 13 and first spring 14, which are symmetrically arranged inside the protective shell 2. One end of the telescopic rod 13 is fixed to the protective shell 2 and the other end is fixed to the clamping plate 11, which can guide the movement direction of the clamping plate 11 and prevent the clamping plate 11 from tilting under the push of the threaded tube 10. The first spring 14 on the surface of the telescopic rod 13 can use its own elasticity to form a buffer for the clamping plate 11. When the clamping plate 11 contacts the movable rod 15, the rebound force of the first spring 14 can ensure the continuous clamping force of the clamping plate 11 on the movable rod 15, ensuring reliable clamping.

[0034] Please see Figure 1 , Figure 4 and Figure 5 The support plate 19 has multiple sets of slots 27 evenly arranged on its surface. These slots 27 match the locking blocks 25. One end of the limiting rod 23 is fixedly connected to a handle 26. The multiple sets of slots 27 evenly arranged on the surface of the support plate 19 can cooperate with the locking blocks 25 to achieve multiple positions of the movable frame 21 on the support plate 19. Operators can flexibly adjust the lateral support position of the movable frame 21 according to the planting density of the crops to adapt to the support needs of different crops. The handle 26 at the end of the limiting rod 23 provides a convenient point of force for pulling the limiting rod 23, facilitating quick control of the separation or engagement of the locking blocks 25 and the slots 27. To simplify the position adjustment process of the movable frame 21, a fixing plate 31 is fixedly connected to the bottom end of the fixing tube 1, and a fixing cone 32 is fixedly connected to the lower surface of the fixing plate 31. There are multiple fixing cones 32, which are evenly arranged on the lower surface of the fixing plate 31. The fixing plate 31 at the bottom end of the fixing tube 1 can increase the contact area between the support frame and the ground, reduce the pressure of the support frame on the ground, and prevent the support frame from sinking into the soft soil due to its own weight or the weight of the crops. The multiple fixing cones 32 on the lower surface of the fixing plate 31 can penetrate into the ground to form multi-point fixation, which significantly enhances the bonding strength between the support frame and the ground, prevents the support frame from tipping over under the action of external forces such as wind and crop pull, and improves the overall stability.

[0035] The implementation principle of this application embodiment is as follows: First, the fixing plate 31 at the bottom of the fixing tube 1 is placed against the planting ground. By pressing or tapping the upper surface of the fixing plate 31 with external force, multiple fixing cones 32 on the lower surface of the fixing plate 31 are vertically drilled into the ground. Utilizing the gripping force of the fixing cones 32 and the ground contact area of ​​the fixing plate 31, the bottom of the support frame is firmly fixed in the planting position to prevent bottom displacement during subsequent adjustments and use. According to the current growth height of the crop, the movable rod 15 is manually pushed to move along the axial direction of the fixing tube 1. At the same time, the surface of the movable rod 15... The slider 17 slides synchronously within the groove 16 inside the fixed tube 1, ensuring a vertical direction of movement. When the support plate 19 at the top of the movable rod 15 reaches the target height, the operator rotates the first rotating shaft 4 via the knob 8. The first rotating shaft 4 then drives the second rotating shaft 6 inside the transmission worm gear 7 to rotate via the transmission worm 5. The second rotating shaft 6 then drives the threaded tube 10 on the surface of the threaded column 9 to push the clamping plate 11 to move. When the anti-slip pad 12 on the surface of the clamping plate 11 is tightly attached to the surface of the movable rod 15, the operator... The operator stops rotating knob 8, then aligns the movable rod 15 with the threaded hole 18 on the surface of the support plate 19, inserts the fixing bolt 20 into the threaded hole 18 and tightens it to fix the movable rod 15 to the support plate 19, completing the support height adjustment. Then, the operator holds the handle 26 at the end of the limiting rod 23 and pulls the limiting rod 23 upward. The limiting rod 23 moves axially along the limiting groove 22 and compresses the second spring 24, causing the bottom locking block 25 to disengage from the locking groove 27 on the surface of the support plate 19. At this time, the movable frame 21 can be pushed laterally along the surface of the support plate 19. Adjust the movable frame 21 to the position where the crop stem needs support; release the handle 26, the second spring 24 returns to its elastic deformation, pushes the limit rod 23 downward, so that the locking block 25 is locked into the corresponding slot 27 of the support plate 19, thus fixing the position of the movable frame 21 and achieving precise positioning of the support point. Place the counterweight 30 at the bottom of the traction rope 29 on the ground around the support frame to keep the traction rope 29 taut. Then tie the crop stem to the surface of the traction rope 29 to complete the process of supporting the crop.
