However, when using the above device, the positioning rod needs to be drilled into the ground to keep the device stable after it is fixed. However, in daily use, due to the different sizes and heights of fruit trees, if a taller fruit tree is grafted, the length of the positioning rod is limited, and it is impossible to drill into the ground to fix the device. For this reason, the utility model provides a grafting device for fruit tree planting. Utility Model Content

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a grafting device for fruit tree planting, comprising a connecting seat, a connecting rod slidably connected to the interior of the connecting seat, a connecting frame fixedly connected to the top of the connecting rod, a positioning frame fixedly connected to the interior of the connecting frame via a clamping assembly, a fixing mechanism provided at the bottom of the connecting seat, and the fixing mechanism comprising:

[0013] Beneficial effects

[0014] The utility model provides a grafting device for fruit tree planting. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The grafting device for fruit tree planting drives the worm to rotate by rotating the control rod, and the rotation of the worm drives the worm wheel, the rotating rod and the rotating disk to rotate. The rotation of the rotating disk causes the sliding block to slide on the inner surface of the arc groove, so that the sliding blocks and the transmission blocks on both sides slide synchronously to the opposite sides. The transmission block slides on the surface of the transmission rod, and the sliding of the transmission block drives the fixed rod and the fixed block to slide synchronously. The device is fixed to the trunk of the fruit tree by the fixed blocks on both sides. By providing a fixing mechanism, the distance between the two groups of fixed blocks can be flexibly adjusted under the drive of the control rod and the worm. The trunk of the fruit tree is clamped by the fixed blocks, so that the grafting device can be applied to fruit trees of different sizes and stably fixed on the fruit tree, thereby facilitating the subsequent positioning of the grafted support rod by the positioning frame, maintaining the stability of the fruit tree after grafting, and improving the survival rate of the grafted fruit tree.

[0016] (2) The grafting device for fruit tree planting drives the protrusion to rotate by rotating the adjusting block. The rotation of the protrusion causes the moving blocks and the clamping blocks on both sides to slide to the opposite sides synchronously, so that the clamping block is separated from the inner surface of the clamping groove, and the telescopic rod begins to shrink. The clamping spring shrinks synchronously, thereby removing the positioning frame and the clamping plate, which is convenient for rapid replacement of the positioning frame. By providing a clamping assembly, the clamping block and the inner surface of the clamping groove are always kept clamped and fixed under the influence of the elasticity of the clamping spring. At the same time, the clamping plate and the positioning frame can be quickly disassembled by rotating the adjusting block, thereby facilitating replacement of the appropriate positioning frame for fruit tree grafting poles of different sizes and realizing subsequent positioning operations.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A grafting device for fruit tree planting includes a connecting seat 1, a connecting rod 2 is slidably connected to the interior of the connecting seat 1, a connecting frame 3 is fixedly connected to the top of the connecting rod 2, a positioning frame 5 is fixedly connected to the interior of the connecting frame 3 via a clamping assembly 4, and a fixing mechanism 6 is provided at the bottom of the connecting seat 1. The fixing mechanism 6 includes:

[0025] The fixing assembly 61 includes a fixing box 611 mounted on the bottom of the connecting base 1. The inner wall of the fixing box 611 is rotatably connected to a rotating rod 612. The surface of the rotating rod 612 is fixedly connected to a worm gear 613 and a rotating disk 614. The surface of the rotating disk 614 is provided with an arcuate groove 615. The inner surface of the arcuate groove 615 allows a fixing rod 616 to slide through the transmission assembly 7. A fixing block 617 is fixedly connected to one side of the fixing rod 616.

[0026] The control assembly 62 is disposed inside the fixing box 611 .

[0027] A sliding groove is provided on one side of the fixing box 611 , and the fixing rod 616 slides on the inner surface of the sliding groove. The sliding groove is used to slide and limit the fixing rod 616 ; the fixing block 617 is an arc-shaped block.

[0028] In this embodiment, the transmission assembly 7 includes a transmission rod 71 installed on the inner wall of the fixed box 611, and the surface of the transmission rod 71 is slidably connected to a transmission block 72. One side of the transmission block 72 is fixedly connected to a sliding block 73, and the surface of the sliding block 73 is slidably connected to the inner surface of the arc groove 615.

[0029] The transmission rod 71 is used to slide and limit the transmission block 72 .

[0030] In this embodiment, the control assembly 62 includes a control rod 621 rotatably mounted inside the fixed box 611 . A worm 622 is fixedly connected to the surface of the control rod 621 , and the surface of the worm 622 meshes with the surface of the worm wheel 613 .

[0031] One end of the control rod 621 extends through the outside of the fixing box 611 , and a control block is installed at one end of the control rod 621 .

[0032] In this embodiment, the clamping assembly 4 includes an adjusting block 41 rotatably mounted on the rear side of the connecting frame 3 and a telescopic rod 42 fixedly mounted on the inner wall of the connecting frame 3. A protrusion 43 is fixedly connected to one side of the adjusting block 41, and one end of the telescopic rod 42 is fixedly connected to a moving block 44. A clamping block 45 is fixedly connected to one side of the moving block 44, and a clamping spring 46 is fixedly connected to the other side of the moving block 44. One end of the clamping spring 46 is fixedly connected to the inner wall of the connecting frame 3.

[0033] The clamping spring 46 ensures that the surface of the clamping block 45 is always clamped with the inner surface of the clamping groove 9 without being affected by external forces; under the influence of the elasticity of the clamping spring 46, the surface of the protrusion 43 is always in contact with the surface of the moving block 44.

[0034] In this embodiment, the surface of the positioning frame 5 is rotatably connected to a clamping plate 8, the surface of the clamping plate 8 is slidably connected to the interior of the connecting frame 3, and clamping grooves 9 are opened on both sides of the clamping plate 8. The inner surface of the clamping groove 9 is clamped to the surface of the clamping block 45.

[0035] The positioning frame 5 is set on the top of the clamping plate 8 through the rotation of the connecting rod and is fixed by bolts. When the rotation angle of the positioning frame 5 is adjusted, the bolt is rotated so that one end of the bolt fits into the surface of the connecting rod, thereby limiting the connecting rod and keeping the rotation angle of the positioning frame 5 fixed.

[0036] In this embodiment, multiple groups of limiting holes 10 are opened on the rear side of the connecting seat 1, and the internal threads of the limiting holes 10 are connected to the limiting bolts 11. The bottom end of the connecting rod 2 is fixedly connected to the connecting plate 12, and the surface of the connecting plate 12 is provided with a connecting hole 13. The inner surface of the connecting hole 13 is threadedly connected to the surface of the limiting bolt 11.

[0037] By matching the limiting bolts 11 with the corresponding limiting holes 10 , the height of the connecting plate 12 can be adjusted and positioned, thereby freely adjusting the height of the positioning frame 5 .

[0038] The grafting device for fruit tree planting drives the worm 622 to rotate by rotating the control rod 621. The rotation of the worm 622 drives the worm wheel 613, the rotating rod 612 and the rotating disk 614 to rotate. The rotation of the rotating disk 614 causes the sliding block 73 to slide on the inner surface of the arc groove 615, so that the sliding blocks 73 and the transmission blocks 72 on both sides slide synchronously to the opposite sides. The transmission block 72 slides on the surface of the transmission rod 71. The sliding of the transmission block 72 drives the fixed rod 616 and the fixed block 617 to slide synchronously. The fixing blocks 617 on both sides fix the device on the trunk of the fruit tree. By providing a fixing mechanism 6, the distance between the two sets of fixing blocks 617 can be flexibly adjusted under the drive of the control rod 621 and the worm 622. The fixing blocks 617 are used to clamp the trunk of the fruit tree, so that the grafting device can be suitable for fruit trees of different sizes and stably fixed on the fruit tree, thereby facilitating the subsequent positioning of the grafted support rod by the positioning frame 5, maintaining the stability of the fruit tree after grafting, and improving the survival rate of the grafted fruit tree.

[0039] The grafting device for fruit tree planting drives the protrusion 43 to rotate by rotating the adjusting block 41. The rotation of the protrusion 43 causes the movable blocks 44 and the clamping blocks 45 on both sides to slide synchronously to opposite sides, so that the clamping blocks 45 are separated from the inner surface of the clamping groove 9, and the telescopic rod 42 begins to shrink. The clamping spring 46 shrinks synchronously, thereby taking out the positioning frame 5 and the clamping plate 8, which is convenient for rapid replacement of the positioning frame 5. By providing a clamping assembly 4, the clamping block 45 and the inner surface of the clamping groove 9 are always kept clamped and fixed under the influence of the elasticity of the clamping spring 46. At the same time, the clamping plate 8 and the positioning frame 5 can be quickly disassembled by rotating the adjusting block 41, thereby facilitating the replacement of the appropriate positioning frame 5 for fruit tree grafting poles of different sizes and realizing subsequent positioning operations.

[0040] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0041] During operation, the worm 622 is driven to rotate by rotating the control rod 621, and the rotation of the worm 622 drives the worm wheel 613, the rotating rod 612 and the rotating disk 614 to rotate. The rotation of the rotating disk 614 causes the sliding block 73 to slide on the inner surface of the arc groove 615, so that the sliding blocks 73 and the transmission blocks 72 on both sides slide synchronously to the opposite sides, and the transmission block 72 slides on the surface of the transmission rod 71. The sliding of the transmission block 72 drives the fixing rod 616 and the fixing block 617 to slide synchronously, and the device is fixed to the trunk of the fruit tree through the fixing blocks 617 on both sides. Then, the height of the connecting frame 3 and the positioning frame 5 is adjusted by the limit bolts 11, and the positioning frame 5 is put on the grafting support rod, and the fixing block 72 is loosened. Open the bolts on the top of the clamping plate 8 and adjust the rotation angle by rotating the positioning frame 5. Finally, fix the positioning frame 5 to the surface of the grafting support rod by rotating the fixing bolts on the surface of the positioning frame 5, so as to maintain the stability of the grafting support rod in the subsequent growth process and improve the survival rate. To adapt to fruit grafting supports of different sizes, the protrusion 43 can be driven to rotate by rotating the adjusting block 41. The rotation of the protrusion 43 causes the moving blocks 44 and the clamping blocks 45 on both sides to slide synchronously to the opposite sides, so that the clamping blocks 45 are separated from the inner surface of the clamping groove 9, so that the telescopic rod 42 begins to contract, and the clamping spring 46 contracts synchronously, thereby taking out the positioning frame 5 and the clamping plate 8, which is convenient for quick replacement of the positioning frame 5.
