Description
Technical Field
[0001] This invention belongs to the field of plant protection technology and relates to a plant trunk auxiliary support device for plant protection. Background Technology
[0002] In the early stages of plant growth, the root system is not yet fully developed. At this time, the root system provides less support for the plant trunk, and to prevent the plant from tipping over, it is necessary to provide auxiliary support for the trunk.
[0003] The core drawback of existing plant trunk support devices lies in their insufficient adjustability. The raising and lowering of the support components relies on multiple positioning screws, meaning that adjusting the length or height requires loosening and retightening these screws one by one, a time-consuming and labor-intensive process with low efficiency. Furthermore, it cannot flexibly adapt to changes in the thickness of plant trunks at different growth stages or among different varieties, resulting in a rigid and fixed support range. This limits the device's versatility and application scenarios. Summary of the Invention
[0004] To address the problems existing in the background art, the present invention proposes a plant trunk auxiliary support device for plant protection.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A plant trunk auxiliary support device for plant protection includes a support rod, a handle fixedly installed at the top end of the support rod, and a ground spike fixedly installed at the bottom end of the support rod; a rectangular groove is formed on the side wall of the support rod, and multiple sliders are slidably installed inside the rectangular groove; two connecting rods are fixedly installed on the side wall of each slider; a fixed seat is fixedly installed at the end of each connecting rod away from the slider; a rotating block is rotatably installed on each fixed seat; a rectangular sleeve is fixedly installed on each rotating block; a movable plate is fitted inside the rectangular sleeve; and a support plate is threadedly connected to one end of the movable plate extending inside the rectangular sleeve.
[0006] The present invention is further configured such that guide grooves are provided on both sides of the interior of the rectangular groove, and limit sliders are integrally formed on both sides of the slider, with the limit sliders slidingly engaging with the guide grooves.
[0007] The invention is further configured such that a rectangular through hole is provided on the upper end face of the slider, a rotating shaft is rotatably mounted on the side of the slider away from the connecting rod, a handwheel is fixedly mounted on one end of the rotating shaft, the other end of the rotating shaft extends into the rectangular through hole and a gear is fixedly mounted thereon, guide grooves are provided on both sides of the slider corresponding to the upper and lower ends of the gear, toothed plates are slidably mounted in the guide grooves, and the toothed plates are meshed with the gears; a plurality of limiting grooves are evenly provided in the guide grooves, and one end of the toothed plate extending out of the guide groove is inserted into the limiting groove.
[0008] The present invention is further configured such that the support plate is composed of three semi-circular rings with increasing radii connected end to end; the openings of the two support plates located on the same slider are arranged opposite each other.
[0009] The invention is further configured such that a plurality of positioning holes are evenly provided on the movable plate, a fixing tube is fixedly installed on the rectangular sleeve, and an insert rod is slidably installed inside the fixing tube. The insert rod slides through the rectangular sleeve and is inserted into the positioning hole. A spherical end cap is fixedly installed at the top of the insert rod, and a return spring is sleeved on the outside of the insert rod. The two ends of the return spring abut against the spherical end cap and the fixing tube, respectively.
[0010] The present invention is further configured such that the fixed base and the rotating block are respectively provided with mounting holes and are tightly connected by fastening bolts.
[0011] The invention is further configured such that a storage groove is provided on both sides of the bottom end of the support rod, and a rotating frame is rotatably installed inside the storage groove. An auxiliary ground spike is rotatably installed inside the rotating frame via a rotating shaft. A groove is provided at the top of the rotating frame, and a protrusion is fixedly installed on the top surface inside the storage groove. The protrusion engages with the groove.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This plant trunk support device for plant protection is equipped with a handwheel, gears, toothed plates, limiting sliders, and guide grooves with limiting slots. The operator turns the handwheel clockwise, driving the gears to rotate and causing the toothed plates on both sides to retract inwards, disengaging their ends from the limiting slots and releasing the slider from its locking position. At this point, the slider can freely slide along the guide groove to the desired height. After positioning, turning the handwheel counterclockwise drives the toothed plates to reset outwards and re-insert into the corresponding limiting slots, completing the locking process. This ensures precise and efficient adjustment of the support height while maintaining stability under load.
[0013] 2. This plant trunk support device for plant protection comprises fastening bolts, a rotating block, a fixed base, a rectangular sleeve, a movable plate, an insert rod, a return spring, and replaceable support plates. During adjustment, first loosen the fastening bolts to allow the rotating block to freely rotate the support plate to the optimal support angle, then lock it. Next, pull up the insert rod to release the lock, and pull out the movable plate to adjust the radial distance of the support plate. After releasing, the insert rod automatically returns to its locked position under the action of the spring. Furthermore, the support plate can be quickly replaced via a threaded connection. This allows for flexible and precise adjustment of the support angle and distance, and can adapt to trunks of different thicknesses by replacing components, improving the adaptability and support effect of the device.
[0014] 3. This plant trunk support device for plant protection consists of a handle, support rod, ground spikes, storage slot, rotating frame, and auxiliary ground spikes, which are secured by a locking mechanism using grooves and protrusions. During operation, the user holds the handle and vertically inserts the ground spike at the bottom of the support rod into the ground; then, the rotating frame is pulled out from the storage slot and rotated to a horizontal position. The auxiliary ground spikes then naturally droop and penetrate the soil under gravity, forming a stable triangular support with the main ground spikes. Multi-point anchoring enhances the device's wind and toppling resistance, and its retractable design allows the device to remain compact when not in use, facilitating safe storage and transportation.

Detailed Implementation
[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] like Figures 1-6As shown, the technical solution adopted by the present invention is as follows: A plant trunk auxiliary support device for plant protection includes a support rod 1, a handle 2 fixedly installed at the top end of the support rod 1, and a ground spike 3 fixedly installed at the bottom end of the support rod 1. A rectangular groove 4 is formed on the side wall of the support rod 1, and multiple sliders 5 are slidably installed inside the rectangular groove 4. A rectangular through hole 14 is formed on the upper end face of the slider 5, and a rotating shaft 15 is rotatably installed on the side of the slider 5 away from the connecting rod 6. A handwheel 32 is fixedly installed at one end of the rotating shaft 15; the other end of the rotating shaft 15 extends into the rectangular through hole 14 and a gear 16 is fixedly installed therein. Guide grooves 17 are formed on both sides of the slider 5 corresponding to the upper and lower ends of the gear 16, and toothed plates 18 are slidably installed in the guide grooves 17, and the toothed plates 18 are meshed with the gears 16. Guide grooves 12 are formed on both sides of the rectangular groove 4, and limit sliders 13 are integrally formed on both sides of the slider 5, and the limit sliders 13 are slidably engaged with the guide grooves 12. Several limiting grooves 19 are evenly provided in the guide groove 12, and one end of the toothed plate 18 extending out of the guide groove 17 is inserted into the limiting groove 19. The linkage mechanism between the gear 16 and the toothed plate 18 realizes convenient adjustment and reliable locking of the height of the slider 5, so that the device can flexibly adapt to the support needs of plants at different heights.
[0018] Two connecting rods 6 are fixedly installed on the side wall of the slider 5. A fixed seat 7 is fixedly installed on the end of each connecting rod 6 opposite to the slider 5. A rotating block 8 is rotatably mounted on each fixed seat 7. The fixed seat 7 and the rotating block 8 have corresponding assembly holes and are tightly connected by fastening bolts 25. Through the cooperation between the rotating block 8 and the fixed seat 7, and the tightening of the fastening bolts 25, the support angle is flexibly adjustable, thus more effectively conforming to and supporting plant trunks with different growth postures.
[0019] A rectangular sleeve 9 is fixedly installed on each rotating block 8. A movable plate 10 is fitted inside the rectangular sleeve 9 for limiting transition. Multiple positioning holes 20 are evenly distributed on the movable plate 10. A fixed tube 21 is fixedly installed on the rectangular sleeve 9. An insertion rod 22 is slidably installed inside the fixed tube 21, sliding through the rectangular sleeve 9 and engaging with the positioning holes 20. A spherical end cap 23 is fixedly installed at the top of the insertion rod 22. A return spring 24 is sleeved on the outside of the insertion rod 22, with its two ends abutting against the spherical end cap 23 and the fixed tube 21, respectively. A support plate 11 is threadedly connected to one end of the movable plate 10 extending inside the rectangular sleeve 9. The support plate 11 consists of three semi-circular rings with increasing radii connected end to end; two support plates 11 located on the same slider 5 have their openings facing each other. The insertion rod 22 and the positioning hole 20 enable quick adjustment and fixation of the extension length of the support plate 11. Combined with the design of replaceable and opposing openings for multiple specifications of support plates, the device's adaptability to plant trunks of different thicknesses and its wrapping and fixing effect are improved.
[0020] The support rod 1 has storage slots 26 on both sides of its bottom end. A rotating frame 27 is rotatably mounted inside each storage slot 26, and an auxiliary spike 29 is rotatably mounted inside each rotating frame 27 via a rotating shaft 28. A groove 30 is provided at the top of each rotating frame 27, and a protrusion 31 is fixedly mounted on the top surface of each storage slot 26, engaging with the groove 30. This expandable and retractable auxiliary spike structure enhances the overall stability of the device in the soil, while the retractable design facilitates transportation and storage.
[0021] Working principle: First, the operator holds the handle 2 and inserts the ground spike 3 at the bottom of the support rod 1 vertically into the ground to initially fix the device. Then, the rotating frame 27 is pulled out from the storage groove 26 at the bottom of the support rod 1, and rotated around the rotation point to a horizontal state parallel to the ground. At this time, the auxiliary ground spike 29 inside the rotating frame 27 hangs down naturally under its own weight or slight downward pressure and penetrates into the soil. The ground spike 3 and the auxiliary ground spike 29 together form a stable triangular support base, which greatly enhances the device's anti-tipping ability in the soil. When the device is not in use, the rotating frame 27 can be rotated in the opposite direction and put back into the storage groove 26. The groove 30 at its top is engaged with the protrusion 31 in the storage groove 26 to ensure that the structure is compact and there are no protruding parts when storing and transporting.
[0022] When the height of the support mechanism needs to be adjusted, the operator turns the handwheel 32 clockwise. The handwheel 32 drives the rotating shaft 15 and the gear 16 fixed at its end to rotate synchronously. The gear 16 meshes with two symmetrically arranged toothed plates 18, driving the toothed plates 18 to slide along the guide groove 17 towards the center, so that their ends completely exit from the limiting groove 19 in the guide slide groove 12, thereby releasing the mechanical lock on the slider 5. At this time, the slider 5 can slide smoothly up and down along the guide slide groove 12 in the rectangular groove 4 through the limiting sliders 13 on both sides to achieve height adjustment. After the slider 5 moves to the target height, the operator turns the handwheel 32 counterclockwise. The gear 16 rotates in the opposite direction and drives the toothed plates 18 to reset outward, so that their ends are inserted into the limiting groove 19 corresponding to the height, relocking the position of the slider 5, ensuring that the height adjustment is efficient and can withstand the continuous pressure from the plant trunk.
[0023] When adjusting the support angle, first use tools or manually loosen the fastening bolts 25 to allow the rotating block 8 to rotate freely within the limit range of the fixed seat 7. Then, the operator can directly rotate the rectangular sleeve 9 to drive the support plate 11 at its end to rotate around the axis of the rotating block 8 to the optimal contact angle with the plant trunk surface. After the angle is determined, tighten the fastening bolts 25 again. The tightening force generated by the bolts will press and fix the rotating block 8 and the fixed seat 7, thereby firmly locking the angle of the entire support unit. This structure allows the support plate 11 to adapt to the natural growth posture of the plant or the bending shape under external force at multiple angles.
[0024] If it is necessary to fine-tune the radial distance of the support plate 11 relative to the plant trunk, the operator can use their fingers to pull the spherical end cap 23 upwards, causing the insertion rod 22 to move upwards against the elastic force of the return spring 24, so that its lower end completely exits the positioning hole 20 on the moving plate 10; then, the moving plate 10 can be freely pulled out, allowing it to slide within the rectangular sleeve 9 to change the extension length of the support plate 11; after the moving plate 10 is adjusted to the appropriate position, the spherical end cap 23 is released, and the restoring force of the return spring 24 will push the insertion rod 22 downwards to automatically reset and insert it into the corresponding positioning hole 20, realizing the quick locking of the moving plate 10. This elastic pin structure realizes the flexible stepless adjustment of the support distance. Furthermore, since the movable plate 10 and the support plate 11 are connected by standard threads, when encountering plant trunks with significant differences in thickness, the original support plate 11 can be manually unscrewed and replaced with a support plate 11 of other specifications, which consists of three semi-circular rings with increasing radii connected end to end. By selecting semi-circular rings with different curvatures and ensuring that the openings of the two support plates 11 on the same slider 5 are set opposite each other, a complete and variable diameter clamping structure can be formed, thereby achieving precise, flexible and reliable support for plants with different diameters at breast height.
