Detailed Description

Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

With reference to fig. 1 to 10, the present application provides a gardening pruning assembly 20, where the gardening pruning assembly 20 includes a centralizing unit 201 and a pruning cutter head 202, the pruning cutter head 202 is disposed behind the centralizing unit 201, and the centralizing unit 201 can rotate to feed the articles to be pruned back to the pruning cutter head 202 for pruning cutter head 202. During rotation of the trimmer cutter disc 202, the trimmed articles are conveyed backwards, and after the articles to be trimmed are conveyed to the trimmer cutter disc 202, the articles can be cut up by the trimmer cutter disc 202, so that trimming of the articles to be trimmed is realized.

According to the horticulture pruning assembly 20 of the embodiment of this application, set up pruning blade disc 202 and the unit 201 of righting that is located its the place ahead, can realize automatic, quick horticulture pruning through the horticulture pruning assembly 20, improve the efficiency of pruning effectively to can promote pruning effect.

The number of the trimming cutter disc 202 of the present application may be one, and after the articles such as branches or lawns are trimmed by the centering unit 201, the articles are cut up by the trimming cutter disc 202. The number of the trimmer disks 202 of the present application may also be plural, for example, when the density of the objects to be trimmed is large or is harder than the density, a plurality of trimmer disks 202 may be provided, the trimming efficiency may be improved by trimming the plural trimmer disks 202, and the omission phenomenon may be prevented.

The centering unit 201 of the present application may be configured to move in a forward and backward direction, and the articles to be trimmed are transferred to the trimmer head 202 for trimming by moving the centering unit 201 backward, and then the centering unit 201 moves forward for the next trimming. Of course, the present application of the centering unit 201 may also be provided in other forms, for example, the centering unit 201 may be provided in a rotatable form to achieve better circulation and quick cutting work. The present application mainly uses the example of the centering unit 201 being rotatable, but this is not a limitation to the scope of the present application. The righting unit 201 can comprise a rotatable rake structure or a deflector rod structure and the like, wherein the rake structure or the deflector rod structure extends out along the radial direction of the rotation axis of the rake structure or the deflector rod structure so as to righting the branches and leaves to be pruned backwards when rotating; the axis of the rotating shaft of the righting unit can be arranged to extend in the left-right direction or in the up-down direction. For example, when the rotating shaft of the centering unit 201 is disposed in front of the left side and/or in front of the right side of the trimmer head 202, the rotating shaft axis of the centering unit 201 may be disposed to extend in the up-down direction. When the rotating shaft of the centering unit 201 is arranged right ahead of the trimming cutter head 202, the axis of the rotating shaft of the centering unit can be extended in the left-right direction, so that branches and leaves to be trimmed can be centered more uniformly, and the trimming effect is better.

As shown in fig. 3 and 4, in some embodiments of the present application, the centering unit 201 may include a rotating shaft 2011 and a rake 2012, the rotating shaft 2011 extends in a left-right direction, the rotating shaft 2011 may rotate around an axis of the rotating shaft 2011, and the rake 2012 is connected to the rotating shaft 2011 and extends in a direction away from the rotating shaft 2011. That is, the rake 2012 has a free end and a fixed end, the fixed end of the rake 2012 is fixed to the rotating shaft 2011, and the free end of the rake 2012 extends along the radial direction of the rotating shaft 2011 in a direction away from the rotating shaft 2011. Alternatively, the rake 2012 extends radially away from the rotational axis 2011 from the fixed end to the free end along the rotational axis 2011.

In addition, in a direction in which the rake 2012 is away from the rotating shaft 2011, the rake 2012 is configured in an arc shape inclined in the same direction as the rotating direction of the rotating shaft 2011. That is, the rake 2012 gradually moves away from the rotating shaft 2011 in the radial direction of the rotating shaft 2011 while extending from the fixed end to the free end, and at the same time inclines toward the same direction as the rotating direction of the rotating shaft 2011. Moreover, when the rake 2012 approaches the trimmer head 202, the rake 2012 forms a concave shape with an upward opening to facilitate the trimmed articles to be caught by the rake 2012, so as to convey the trimmed articles to other locations for recycling. The rake 2012 may include a plurality of spaced-apart portions along the circumference of the rotational shaft 2011. So that the material can be continuously fed to the trimmer cutter head 202 by the plurality of rotating rakes 2012, thereby realizing rapid trimming.

In addition, to facilitate the transfer of the articles to be trimmed to trimmer cutter deck 202, the articles to be trimmed can be transferred to the corresponding position on trimmer cutter deck 202 for trimming when rotating rake 2012 backwards. For example, the distance between the free end of the rake 2012 and the axis of the rotating shaft 2011 is L1, and the distance between the axis of the rotating shaft 2011 and the outer edge of the cutter 2022 of the trimmer cutter head 202 is L2, where L1 may be set to be equal to or less than L2, so that the centering unit 201 may center and convey the material to the trimmer cutter head 202 for trimming by the trimmer cutter head 202.
