DETAILED DESCRIPTION

[0034] The specific embodiments described hereinbelow will be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0035] AsFigures 1-5 The utility model provides a kind of fruit tree pruning device, the fruit tree pruning device includes: support rod 1, support seat 2, movable plate 3 and pruning mechanism;

[0036] The top of the length-adjustable support rod 1 is horizontally fixed with a support seat 2, and the upper part of the support seat 2 is hingedly connected with an angle-adjustable movable plate 3, which is provided with a pruning mechanism.

[0037] The upper end of the movable plate 3 is provided with two pruning knives 4 hingedly connected together in an X shape, and the handles of the two pruning knives 4 below the hinge point are connected together by a spring 5. The movable plate 3 is provided with a driving mechanism 6 that can push the handles of the two pruning knives 4 closer together to make the blades of the two pruning knives 4 closer together for pruning.

[0038] In the above-mentioned scheme, during use, the height of the pruning mechanism can be adjusted by adjusting the length of the support rod 1, so that the pruning mechanism can prune branches and leaves at a higher position.

[0039] The angle of the pruning mechanism can also be indirectly adjusted by adjusting the angle of the movable plate 3, so that branches and leaves at different positions can be better pruned.

[0040] In addition, the blades of the two pruning knives 4 hingedly connected together are driven by the driving mechanism 6 to move closer to each other to prune branches and leaves clamped between them, without the need for manual operation of the pruning knives 4 to prune branches and leaves, saving time and effort.

[0041] Therefore, the fruit tree pruning device provided by the utility model has height and pruning angle adjustment functions, can prune branches and leaves at different heights of fruit trees and at different positions, improves the flexibility and reliability of the entire device, and thus facilitates pruning of fruit trees.

[0042] In a preferred embodiment of the utility model, the driving mechanism 6 includes an electromagnet 601, a driving block 602, and a driving rod 603.

[0043] The interior of the movable plate 3 is hollow, and two driving blocks 602 with magnetic force and opposite magnetic force are movably arranged in the interior and can be close to or away from each other. The two driving blocks 602 are connected together by the second spring 10. The two ends of the interior of the movable plate 3 are respectively fixedly provided with electromagnets 601 with the same magnetic force as the adjacent driving blocks 602 after being powered on. The upper ends of the two driving blocks 602 located outside the two handle bars are respectively horizontally fixedly provided with driving rods 603 capable of penetrating out of the interior of the movable plate 3 and abutting against the handle bars corresponding thereto. A strip-shaped hole is formed in the side wall of the movable plate 3 and communicates with the interior thereof and is used for the two driving rods 603 to penetrate out.

[0044] In the above scheme, the movable plate 3 is further fixedly provided with a storage battery (not shown in the figure) for providing electric energy to the two electromagnets 601. During use, the two electromagnets 601 are turned on to generate magnetic force. The two electromagnets 601 after being powered on have the same magnetic force as the adjacent driving blocks 602, respectively. Repulsive force is generated between the two electromagnets 601 and the two driving blocks 602, respectively. Under the action of the repulsive force, the two driving blocks 602 are driven to be close to each other to push the handle bars of the two trimmers 4 to be close, so that the cutting edges of the two trimmers 4 are also close to each other to perform trimming operation. In addition, during the process that the two driving blocks 602 are close to each other, the second spring 10 is in a compressed state. At the same time, during the process that the two driving blocks 602 are driven to be close to each other to push the handle bars of the two trimmers 4 to be close, the first spring 5 is also in a compressed state. After trimming is completed, the two electromagnets 601 are powered off. The two electromagnets 601 after being powered off lose magnetic force, and the repulsive force generated between the two electromagnets 601 and the two driving blocks 601 disappears. Under the action of the second spring 10, the two driving blocks 602 move reversely and return to the initial positions thereof. At the same time, the handle bars of the two trimmers 4 also move reversely and return to the initial positions thereof under the action of the first spring 5.

[0045] In addition, the two electromagnets 601 can be replaced by a lead screw. The lead screw is composed of two screw rods with opposite screw directions. The lead screw is horizontally and rotatably arranged in the movable plate 3. The two driving blocks 602 are horizontally provided with threaded holes which are threadedly connected together with the two screw rods. The lead screw is coaxially connected together with a motor which is horizontally fixed in the movable plate 3 through a shaft coupling. Therefore, the two driving blocks 602 can be driven to be close to or away from each other by rotating the lead screw to push the cutting edges of the two trimmers 4 to be close to each other to perform trimming operation.

[0046] In a preferred embodiment of the utility model, the inside of the movable plate 3 above the two electromagnets 601 is horizontally fixedly provided with a guide rod 9, two guide holes for the guide rod 9 to pass through are horizontally provided on the two driving blocks 602 respectively, and a second spring 10 is sleeved on the guide rod 9 between the two driving blocks 602, and the two ends of the second spring 10 are fixed on the two driving blocks 602 respectively.

[0047] In the above scheme, through the cooperation of the guide rod 9 and the two guide holes on the two driving blocks 602, the two driving blocks 602 can be stably and reliably moved back and forth on the guide rod 9.

[0048] In a preferred embodiment of the utility model, a rubber pad 11 is fixedly arranged on each driving block 602 facing the electromagnet 601.

[0049] In the above scheme, when the two electromagnets 601 are powered off, the two driving blocks 602 approach the corresponding electromagnets 601 under the action of the second spring 10, which plays a protective role and prevents the driving blocks 602 from deforming by colliding with the electromagnets 601.

[0050] In a preferred embodiment of the utility model, the device further comprises an angle adjusting mechanism 7 for adjusting the angle of the movable plate 3, and the angle adjusting mechanism 7 comprises: an adjusting gear 701, an adjusting tooth plate 702 and an electric telescopic rod 703; wherein,

[0052] In the above scheme, during the movement of the electric telescopic rod 703 through the connecting plate to drive the two adjusting tooth plates 702 to move in the horizontal direction, the two adjusting gears 701 can be driven to rotate, thereby the movable plate 3 can be driven to flip along the hinge to adjust the angle of the movable plate 3, thereby indirectly adjusting the trimming angle of the trimming knife 4.

[0053] In addition, the electric telescopic rod 703 is a servo cylinder, and the servo cylinder is a modular product integrating a servo motor and a screw rod, and the speed thereof is 0.1-2 m / s. Because of closed-loop servo control, the control precision is high. The servo cylinder has the characteristics of low cost and flexible configuration, and is the best alternative to a hydraulic cylinder and a pneumatic cylinder. Therefore, the servo cylinder is prior art, and the specific structure and use principle thereof will not be described herein.
