Description

Technical Field

[0001] The utility model relates to the technical field of fruit seedling pruning, in particular to a device for pruning fruit seedling branches. Background Technique

[0002] Fruit seedlings refer to the seeds or seedlings extracted from fruits in the planting industry, which are used to plant new fruit trees. After these seedlings are cultivated and planted, they will grow into mature fruit trees and bear fruits. Before selling fruit seedlings such as kumquat seedlings and cherry seedlings, it is necessary to ensure that, for the convenience of transportation, generally the branches need to be cut off, and the trunk also needs to be fixed to a certain length to promote branching and early shaping. During the daily maintenance process of fruit seedling branches, traditional pruning methods often pose many challenges to operators. On the one hand, operators often need to firmly hold the fruit seedling pot with one hand and hold the pruning tool with the other hand for delicate operations. This long-term holding not only requires operators to have high physical strength and endurance, but also as the pruning time prolongs, the arm holding the fruit seedling pot is extremely prone to soreness, resulting in increased operator fatigue, and the pruning efficiency and quality also decline accordingly. On the other hand, some operators choose to directly place the fruit seedling pot on the ground for pruning to relieve the pressure on the arm. Ground pruning limits the operator's operation perspective and the range of arm movement. Especially for branches at high and low positions, the pruner has to frequently adjust the posture and even needs to use auxiliary tools, which not only reduces the work efficiency. Therefore, a device for pruning fruit seedling branches is proposed to solve the above-mentioned problems. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model proposes a device for pruning fruit seedling branches, including an outer ring body. A plurality of legs are welded to the outer wall of the outer ring body, and the ends of the legs far away from the outer ring body are in contact with the ground. A circular inner ring is arranged inside the outer ring body, and the circular inner ring slides up and down along the height direction of the outer ring body. A placement frame for holding saplings is arranged inside the circular inner ring. A collection bucket for collecting waste branches is arranged directly below the outer ring body. A jacking device for driving the circular inner ring to move up and down is arranged on one of the legs.

[0004] Further, a plurality of connecting arms are welded to the outer side of the circular inner ring and are distributed at equal intervals in a ring shape. Sliding grooves adapted to the connecting arms are formed on the outer ring body, and the number of the sliding grooves matches the number of the connecting arms. The ends of the connecting arms far away from the circular inner ring are slidably connected to the adjacent sliding grooves.

[0005] Further, the placement frame is rotatably connected inside the circular inner ring. An annular groove is formed on the inner wall of the circular inner ring, and a plurality of balls are arranged in the annular groove.

[0006] Further, a mounting plate is welded on the support leg, the lifting device is arranged on the plate surface of the mounting plate, and a reinforcing plate is welded between the mounting plate and the support leg.

[0007] Further, an installation area is provided on the collection barrel, and the lifting device is located within the installation area.

[0008] Further, a plurality of rubber strips are arranged at the opening edge of the top of the placement frame and are evenly distributed at equal intervals in a ring shape. One end of the rubber strip away from the placement frame converges towards the center of the placement frame, and a handle is arranged on the outer wall of the placement frame.

[0009] The beneficial effects of the present utility model are as follows: By arranging a slidable annular inner ring up and down within the outer ring body and equipping it with a lifting device to drive its movement, the operator can easily adjust the height of the fruit seedlings without frequently bending down or standing on tiptoe, thereby reducing the labor intensity and improving the pruning efficiency. The placement frame arranged within the annular inner ring can rotate. Combined with the design of the ball, the fruit seedlings can rotate smoothly during the pruning process. The two are used in combination, facilitating the operator to prune from various angles and improving the fineness and uniformity of pruning. Description of the Drawings

[0015] In the embodiment, it is given by Figure 1 A pruning device for fruit tree seedlings includes an outer ring body 1. A plurality of legs 2 are welded to the outer wall of the outer ring body 1. One end of the leg 2 away from the outer ring body 1 contacts the ground. A circular inner ring 3 is arranged inside the outer ring body 1, and the circular inner ring 3 slides up and down along the height direction of the outer ring body 1. A placement frame 4 for holding saplings is arranged inside the circular inner ring 3. A collection bucket 5 for collecting waste branches is arranged directly below the outer ring body 1. A jacking device 6 for driving the circular inner ring 3 to move up and down is arranged on one of the legs 2. A placement frame 4 for holding fruit tree seedlings to be pruned is arranged inside the circular inner ring 3, which can stably fix the fruit tree seedlings, keep them upright and not easy to shake during the pruning process, facilitating subsequent pruning operations. At the same time, a storage box for preventing tools is arranged on the outside of the outer ring body 1. During the pruning process, the pruner can use various pruning tools to finely prune the branches of the fruit tree seedlings. The waste branches generated during the pruning process will naturally fall into the collection bucket 5 directly below the outer ring body 1, effectively avoiding the waste branches from scattering all over the place, reducing the workload of subsequent cleaning, and at the same time keeping the pruning site clean. The jacking device 6 adopts the existing technology and can be directly purchased from the market. Its working principle is the same as that of a lifting barber chair, that is, the operator steps on the pedal to move the telescopic end up and down, thereby driving the circular inner ring 3 and the placement frame 4 inside it to move up and down along the height direction of the outer ring body 1, so that the pruner can adjust the height of the fruit tree seedlings according to needs for more convenient pruning.

[0016] Referring to Figure 1 , wherein, a plurality of connecting arms 7 distributed at equal intervals in a ring are welded to the outer side of the circular inner ring 3.
