Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural planting, in particular to a fruit tree pruner. Background Art
[0002] The rootstock refers to the plant that bears the scion during grafting. The rootstock can be the whole fruit tree or the root or branch of the tree. It can stabilize the soil, improve the plant's own resistance to diseases and insects, and form the role of plant growth and fruiting after healing with the scion. The rootstock is the basis of the grafted fruit tree seedlings. The selected grafting affinity is good, the seedling life is long, and it is easy to cultivate.
[0003] As we all know, fruit tree seedlings usually need to be propagated through grafting, combining the rootstock and scion together to form a new plant. Grafting is generally divided into branch grafting and bud grafting. Seedlings propagated through branch grafting grow well and take shape quickly. However, before grafting, the rootstock usually needs to be pruned, which is called rootstock pruning. It means that before grafting in the nursery, the rootstock needs to be kept about 5-10 cm away from the ground, and the rest is all cut off. The cut edge must be clean and flat, with the same height, and it will be used for the next step of grafting.
[0004] Due to the lack of special pruning tools, pruning operations mainly rely on ordinary branch shears. Since the pruning stock is close to the ground, workers need to bend over repeatedly, which is time-consuming and labor-intensive. Pruning is extremely inconvenient, and there is no way to ensure that the pruning height is uniform. This directly affects the uniformity of the seedlings when they are planted, and cannot meet the requirements of the modern seedling market. Utility Model Content

The upper surface of the fixed scissor 22 is coplanar with the upper surface of the fixing plate 21. A hinge shaft 211 perpendicular to the fixing plate 21 is fixedly connected to the upper surface of the fixing plate 21. An active scissor 23 adapted to the fixed scissor 22 is rotatably connected to the hinge shaft 211, that is, the blade of the active scissor 23 is adapted to the blade of the fixed scissor 22. A driven gear 24 is rotatably connected to the hinge shaft 211 above the active scissor 23. The driven gear 24 is fixedly connected to the active scissor 23. A driving motor 25 is fixedly connected to the bottom surface of the fixing plate 21. The rotating shaft of the driving motor 25 extends out of the fixing plate 21 and is fixedly connected to a driving gear 26 meshing with the driven gear 24. The rotation of the driving gear 26 can synchronously drive the rotation of the driven gear 24, so that the active scissor 23 and the fixed scissor 2 / 2 are closed or opened. A telescopic positioning part 3 for adjusting the distance between the scissor part 2 and the bottom end of the support rod 1 is provided at the bottom of the support rod 1. A power supply 27 and a controller 28 are provided on the fixing plate 21. The controller 28 is electrically connected to the driving motor 25 and the power supply 27 respectively.
[0027] As shown in Figure 1 , 3 , 4, and 5, the telescopic positioning part 3 of this embodiment includes a telescopic rod 31, a linkage gear 32, a ratchet wheel 33, a ratchet pawl 34, a torsion spring 35, and a release rod 36. A chute 11 with a lower opening is axially provided at the bottom of the support rod 1. The telescopic rod 31 is slidably arranged in the chute 11. A rack 311 is provided on the outer side of the telescopic rod 31 along the length direction. A placement groove 12 opposite to the rack 311 is opened on the side wall at the bottom of the support rod 1. The placement groove 12 communicates with the chute 11. The linkage gear 32 is arranged in the placement groove 12 and meshes with the rack 311. The two ends of the rotating shaft of the linkage gear 32 are rotatably connected to the support rod 1 on both sides of the placement groove 12. A coaxial ratchet wheel 33 is fixedly connected to one side of the linkage gear 32. A ratchet pawl 34 meshing with the ratchet wheel 33 is provided in the placement groove 12. One end of the ratchet pawl 34 is fixedly connected to a ratchet pawl shaft 341. The two ends of the ratchet pawl shaft 341 are rotatably connected to the support rod 1 on both sides of the placement groove 12. A torsion spring 35 is sleeved on the ratchet pawl shaft 341. One end of the torsion spring 35 abuts against the ratchet pawl 34, and the other end of the torsion spring 35 is fixed to the support rod 1.
[0028] To facilitate the operation of the support rod 1, a horizontal upper handle 13 is provided on one side at the top of the support rod 1, and a lower handle 14 is provided on the other side in the middle of the support rod 1. A start switch 131 is provided on the outer side of the upper handle 13. The start switch 131 is electrically connected to the power supply 27.
[0029] To facilitate the pushing and pulling of the telescopic rod 31, a push rod 312 perpendicular to it is provided at the bottom end of the telescopic rod 31. The two ends of the push rod 312 extend out of the outer edge of the support rod 1. The two ends of the push rod 312 extend out of the outer edge of the support rod 1, which is convenient for holding the ends of the push rod 312 to push the telescopic rod 31 into or out of the chute 11.
[0030] In order to make the support rod 1 perpendicular to the bottom surface during use and ensure the neatness and consistency of the cutting edges, there are two push rods 312. The bottom surfaces of the two push rods 312 are located in the same plane, and the two push rods 312 are distributed in an X shape. The two push rods 312 in this embodiment are arranged perpendicular to each other.
[0031] In order to conveniently control the length of the telescopic rod 31 extending out of the chute 11, the telescopic rod 31 is provided with scale lines 313 along its length direction.
[0032] In order to intuitively know the distance between the bottom end of the support rod 1 and the upper surface of the fixed shear 22, scale lines 313 are provided along the length direction of the support rod 1 between the bottom end of the support rod 1 and the upper surface of the fixed plate 21.
[0033] The push rod 312 is provided with scale lines 313 along the height direction.
[0034] A protective cover 5 fixedly connected to the support rod 1 is sleeved outside the fixed plate 21. A relief groove is provided at the position where the side wall of the protective cover 5 faces the movable shear 23. The provision of the relief groove can prevent interference between the movable shear 23 and the protective cover 5 when the movable shear 23 rotates, facilitating the closing or opening between the movable shear 23 and the fixed shear 22.
[0035] The power source 27 is a rechargeable battery. A charging interface electrically connected to the power source 27 is provided outside the protective cover 5. The use of a rechargeable battery for the power source 27 facilitates the carrying of the trimmer, eliminates the need for an external power source, and improves the convenience of using the trimmer.
[0036] The specific working process of the present utility model is as follows: As Figure 1 、 3 shown, first hold the end of the push rod 312 and pull the telescopic rod 31 outwards to a suitable position. The rack 311 on the telescopic rod 31 drives the linkage gear 32 to rotate, and the linkage gear 32 synchronously drives the ratchet wheel 33 to rotate. The pawl 34 is always pressed against the ratchet wheel 33 under the action of the torsion spring 35, thereby preventing the telescopic rod 31 from being pushed into the chute 11 under an external force, achieving the purpose of adjusting the distance between the upper surface of the fixed shear 22 and the bottom end of the support rod 1, that is, achieving the positioning adjustment of the anvil height. When it is necessary to shorten the length of the telescopic rod 31 extending out of the chute 11, only need to rotate the release rod 36 clockwise, driving the pawl 34 to rotate clockwise. The pawl 34 disengages from the ratchet wheel 33. At this time, push the push rod 312 upwards and push the push rod 312 into an appropriate depth of the chute 11 to freely set the length of the push rod 312 extending out of the chute 11. Then release the release rod 36, and the pawl 34 engages with the ratchet wheel 33 to lock and position the push rod 312. By adding the scale lines 313 on the push rod 312, the telescopic rod 31 and the support rod 1, the height of the rootstock from the ground can be set, meeting the cutting requirements for different heights of seedlings.
[0037] AsFigure 1 , 2 As shown in 2 , after adjusting the height of the support rod 1, turn on the start switch 131. The power supply 27 supplies power to the controller 28. The controller 28 controls the rotation shaft of the drive motor 25 to rotate forward and backward alternately. The rotation shaft of the drive motor 25 drives the drive gear 26 to rotate forward and backward, thereby driving the driven gear 24 to rotate forward and backward, realizing the clockwise or counterclockwise rotation of the movable shear 23, achieving the opening and closing between the movable shear 23 and the fixed shear 22. When the movable shear 23 and the fixed shear 22 are opened, place the rootstock between the movable shear 23 and the fixed shear 22. When the movable shear 23 and the fixed shear 22 are closed, the pruning of the rootstock can be realized.
[0038] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
