Description

Technical Field

[0001] This utility model belongs to the field of large-fruited hawthorn planting technology, specifically relating to a branch pulling device for large-fruited hawthorn branches. Background Technology

[0002] Large-fruited hawthorn (Crataegus pinnatifida) is a plant belonging to the genus Crataegus in the subfamily Pyrenoidae of the family Rosaceae. It is renowned for its large fruit and is a rare variety within the Crataegus genus in my country. The fruit can be eaten fresh or processed into various products such as dried fruit, jam, wine, hawthorn slices, and hawthorn cakes. Rich in various functional components and nutrients, it is hailed as a "nutritious and health-promoting fruit" and is a plant with both medicinal and edible uses. In recent years, the development of the large-fruited hawthorn processing industry has further enhanced its economic benefits. Cultivating large-fruited hawthorn has become an effective way for growers to increase their economic income, which has also promoted the continuous development and expansion of the large-fruited hawthorn industry.

[0003] By pulling the branches of fruit trees such as large-fruited hawthorn, the spatial layout of the branches can be improved, enhancing light penetration and ventilation, which helps to improve fruit quality and yield. Existing technologies disclose branch-pulling devices, such as CN202021094147.9, which discloses a fruit tree branch-pulling device including a first semicircular arc, a second semicircular arc, connecting bolts, and a branch-pulling device. The first semicircular arc is connected to the second semicircular arc via the connecting bolts, and the first and second semicircular arcs are then installed at the base of the fruit tree trunk. The branch-pulling devices on the first and second semicircular arcs connect to the fruit tree branches to pull the branches, thereby achieving the branch-pulling effect.

[0004] Undeniably, the fruit tree branch-pulling device disclosed in this patent can achieve the aforementioned effects, but it also has certain shortcomings: the entire device forms a circle around the bottom of the tree trunk using a first and second semicircular arc, relying on connecting bolts to adjust the tightness. However, the diameter of the fruit tree trunk gradually increases with growth, while the spring's buffering range is limited. Once the trunk diameter exceeds the spring's maximum compression, the device will compress the trunk, causing bark abrasion and xylem damage, affecting the fruit tree's growth. Furthermore, if the trunk has irregular shapes such as protrusions or bends, the two semicircular arcs may not fit tightly against the trunk, causing the device to wobble and reducing its stability.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0022] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0023] See appendix Figure 1-8 A device for pulling branches of large-fruited hawthorn, comprising: Support rod 1; Multiple tie rods 2 are fixed to the top of the support rod 1; Multiple branch-pulling structures 3 are fixed on the branch-pulling rod 2. The branch-pulling structure includes a branch-pulling box 4, a winding wheel 5 rotatably disposed in the branch-pulling box 4, and a branch-pulling cloth strip 6 wound on the winding wheel 5.

[0024] In this embodiment, a fixing cylinder 41 is integrally formed at one end of the branch pulling box 4, and a locking screw 42 is threadedly connected to the outer wall of the fixing cylinder 41; a plurality of grooves 21 corresponding to the inner ends of the locking screws 42 are spaced apart along the axial direction on the outer wall of the branch pulling rod 2; when fixing the branch pulling box 4, the fixing cylinder 41 is sleeved on the branch pulling rod 2, and the locking screw 42 is tightened, so that the inner end of the locking screw 42 enters the groove 21 and abuts against the bottom wall of the inner end of the groove 21; in addition, an opening is left at the end of the branch pulling box 4 away from the fixing cylinder 41, and a sealing plate 43 is snapped at the opening of the branch pulling box 4, and a relief groove 431 is opened in the middle of the sealing plate 43; the inner end of the branch pulling cloth strip 6 is fixedly connected to the winding wheel 5, and the outer end extends out from the relief groove 431.

[0025] In this embodiment, the winding wheel 5 includes a winding drum 51 in the middle and locking discs 52 fixed at both ends of the winding drum 51. Locking grooves 521 are evenly distributed on the locking discs 52. The winding drum 51 has a regular polygonal cross-section insertion groove 511 in the middle, and a limiting groove 512 is also provided at each end of the winding drum 511. A clearance hole 44 is provided at the position corresponding to the limiting groove 512 in the pull box 4. A rotating cylinder 45 is threaded into the clearance hole 44, and the inner end of the rotating cylinder 45 extends into the limiting groove 512. The inner diameter of the rotating cylinder 45 is larger than the diameter of the insertion groove 512. It should be noted that the outer diameter of the rotating cylinder 45 is smaller than the inner diameter of the limiting groove 512, and the inner end of the rotating cylinder 45 does not contact the inner end of the limiting groove 512 to avoid hindering the rotation of the winding wheel 5.

[0026] In this embodiment, an adjusting rod 7 is also provided. The cross-section of the adjusting rod 7 is a regular polygon corresponding to the cross-section of the insertion slot 511. The top of the adjusting rod 7 is integrally formed with a limit cap 71, and the bottom passes through the insertion slot 511 and the rotating cylinder 45 and is threadedly connected to a locking nut 72. Since the inner diameter of the rotating cylinder 45 is larger than the diameter of the insertion slot 512, the adjusting rod 7 can pass smoothly through the rotating cylinder 45, and the rotating cylinder 45 will not interfere with the adjusting rod 7.

[0027] To lock the winding wheel 5, this embodiment also includes a locking structure 8. The locking structure 8 includes a locking tooth 81 corresponding to the size and shape of the locking groove 521, a pressing rod 82 fixed to the top of the locking tooth 81 and passing through the pull box 4 and slidingly engaging with the locking box 4, a limiting plate 83 located at the end of the locking tooth 81 away from the pressing rod 82 and fixed to the side wall of the pull box 4, and a return spring 84 located between the locking tooth 81 and the limiting plate 83. The locking tooth 81 is rectangular on the side near the pull box 4 and fits against the side wall of the pull box 4. One end of the return spring 84 abuts against the locking tooth 81 and the other end abuts against the limiting plate 83. Further, a limiting rod 85 is fixed at the end of the locking tooth 81 away from the pressing rod 82, and the return spring 84 is sleeved on the limiting rod 85. The end of the limiting rod 85 away from the locking tooth 81 passes through the limiting plate 85 and slides with it. It should be noted that the branch box 4 has a through hole corresponding to the pressing rod 82 (not shown in the attached drawing), and the limiting plate 83 has a through hole corresponding to the limiting rod 85 (not shown in the attached drawing).

[0028] In use, the support rod 1 is fixed in the soil near the planting of large-fruited hawthorn. Then, as needed, multiple branch-pulling boxes 4 are fitted onto the branch-pulling rod 2, and the branch-pulling boxes 4 are fixed onto the branch-pulling rod 2 with the help of the locking screw 42. The locking screw 42 is tightened, and the inner end of the locking screw 42 enters the groove 21 and abuts against the bottom wall of the inner end of the groove 21, thus fixing the branch-pulling box 4 onto the branch-pulling rod 2. Then press the pressing rod 82, compress the return spring 84, and disengage the locking tooth 81 from the locking groove 521. At this time, pull the outer end of the branch-pulling strip 6, and the winding wheel 5 rotates. After pulling the branch-pulling strip 6 to a suitable length, release the pressing rod 82 and rotate the adjusting rod 7. The return spring 84 extends and exerts an outward pushing force on the locking tooth 81. The locking tooth 81 moves outward. When the adjusting rod 7 is rotated, the adjusting rod 7 drives the winding drum 51 to rotate. When the locking tooth 81 and the locking groove 521 are aligned, the locking tooth 81 enters the locking groove 521 under the action of the return spring 84, limiting and fixing the locking disc 52, and then locking and limiting the winding wheel 5. Then, tie the outer end of the branch-pulling strip 6 to the fruit tree branch to be pulled.

[0029] When adjusting the length of the branch-pulling strip 6, press the pressing rod 82 to disengage the locking tooth 81 from the locking groove 821. By rotating the adjusting rod 7 to rotate the winding wheel 5, the branch-pulling strip 6 can be wound onto the winding drum 51, shortening the branch-pulling strip 6; or the branch-pulling strip 6 can be pulled outward to increase the length of the branch-pulling strip 6 extending out of the branch-pulling box 4. After adjustment, release the pressing rod 82 and rotate the adjusting rod 7 to allow the locking tooth 81 to re-enter the locking groove 521.
