The number of trimming cutterheads 202 according to the present application may be one, and after trimming articles such as branches or lawns by the centralizing unit 201, the articles are cut by the trimming cutterhead 202. The number of trimming cutterheads 202 of the present application may be plural, for example, when the objects to be trimmed are dense or harder, a plurality of trimming cutterheads 202 may be provided, and trimming by the plurality of trimming cutterheads 202 may improve the trimming efficiency and prevent missing phenomena.
The centering unit 201 of the present application may be configured to be adapted to move in a forward and backward direction, whereby the article to be trimmed is transferred to the trimming blade 202 for trimming by the backward movement of the centering unit 201, and then the centering unit 201 is advanced for the next trimming. Of course, the centering unit 201 of the present application may be provided in other forms, for example, the centering unit 201 may be provided in a rotatable form to achieve better circulation and quick trimming operations. The present application is mainly described by taking the rotatable example of the centering unit 201, but this is not a limitation of the scope of the present application. The centering unit 201 may include a rotatable rake structure or a deflector rod structure, etc., which protrudes in a radial direction of its own rotation axis to center the branches and leaves to be trimmed backward when rotated; the rotation shaft axis of the centering unit may be provided to extend in the left-right direction or in the up-down direction. For example, when the rotation shaft of the centering unit 201 is disposed in front of the left side and/or in front of the right side of the trimming cutter head 202, the rotation shaft axis of the centering unit 201 may be provided to extend in the up-down direction. When the rotating shaft of the centering unit 201 is disposed right in front of the trimming cutter head 202, the rotating shaft axis of the centering unit may be set to extend in the left-right direction, so that the branches and leaves to be trimmed may be more uniformly centered, and the trimming effect is better.

In addition, in a direction in which the rotary rake 2012 is away from the rotary shaft 2011, the rotary rake 2012 is configured in an arc shape inclined in the same direction as the rotation direction of the rotary shaft 2011. That is, the rotating rake 2012 gradually moves away from the rotating shaft 2011 in the radial direction of the rotating shaft 2011 while being inclined in the same direction as the rotating direction of the rotating shaft 2011 in the process of extending from the fixed end to the free end. Moreover, the turning rake 2012 creates an upwardly opening concave shape in the turning rake 2012 when approaching the trimming cutterhead 202 to facilitate the routing of trimmed items through the turning rake 2012 for retrieval to other locations. The rotary rake 2012 may include a plurality of rotary rakes arranged at intervals along a circumferential direction of the rotary shaft 2011. So that rapid trimming may be achieved by the multiple rotating rakes 2012 constantly feeding material to the trimming cutterhead 202.
In addition, to facilitate routing the items to be trimmed to the trimming blade 202, the items to be trimmed may be routed to corresponding locations on the trimming blade 202 for trimming as the rotating rake 2012 is rotated rearward. For example, the spacing between the free end of the rake 2012 and the axis of the shaft 2011 is L1, and the spacing between the axis of the shaft 2011 and the outer edge of the cutter 2022 of the trimming cutter head 202 is L2, where L1 is less than or equal to L2 may be set, so that the centering unit 201 may center and convey the material to the trimming cutter head 202 for trimming by the trimming cutter head 202.

When the rotary rake 2012 rotates along the rotary drawer, the objects to be trimmed are positioned through the gaps between the rake teeth 2013, and are conveyed to the trimming cutter 202 in an upright state under the rotation action of the rotary rake 2012, so that the objects to be trimmed are effectively trimmed, the trimming effect can be achieved, and the trimming efficiency is improved.
The righting unit 201 may further be provided with a pad 2014, gaps between rake teeth 2013 are adjusted through the pad 2014, square tubes can be arranged in the rotating shaft 2011, fixing flanges at two ends of the square tubes can be arranged, the rotating rake 2012 can be provided with a plurality of arc-shaped rake teeth 2013, the rotating shaft 2011 is installed, articles to be trimmed are kept in an upright state under the rotation of the rotating rake 2012 and located between the gaps of the rotating rake 2012, and the articles to be trimmed are trimmed smoothly through the trimming cutter 202. Simple structure, low cost and convenient maintenance.
As shown in fig. 6-9, in some embodiments of the present application, trimming cutter head 202 may include a cutter head shaft 2021, a plurality of cutters 2022, and a power assembly 2023, the cutter head shaft 2021 extending in an up-down direction, and the cutter head shaft 2021 being rotatable about an axis of the cutter head shaft 2021; a plurality of cutters 2022 are mounted on the cutter head shaft 2021 and are arranged in the up-down direction with gaps between the plurality of cutters 2022; the power assembly 2023 is coupled to the cutterhead shaft 2021 to drive rotation of the cutterhead shaft 2021. The cutter head shaft 2021 is driven to rotate by the power assembly 2023, and the cutters 2022 are driven to rotate, so that objects to be trimmed are trimmed, and the trimming efficiency is improved. The plurality of cutters 2022 may have different functions, for example, the plurality of cutters 2022 may each be used for cutting, chopping, etc.
The cutter shaft 2021 and the power assembly 2023 on the trimming cutter 202 may be mounted on a bearing seat of the trimming cutter 202, and the cutter shaft 2011 is connected with the power assembly 2023 to realize force transmission, so that the number of cutters 2022 may be multiple, and the cutters 2022 may also be set into different shapes. The following description is intended to illustrate the present application without being construed as limiting the application, for example, when the number of cutters 2022 is three, an upper cutter 2022, a middle cutter 2022, and a lower cutter 2022 are respectively mounted on the cutter head shaft 2021 in order from top to bottom, the upper cutter 2022 may be an elongated cutter 2022, the middle cutter 2022 may be a small cutter 2022 mounted on a disk, and the number of the middle cutters 2022 may be plural, mounted on the disk, and the upper cutter 2022 may be a disk-type cutter 2022. The object to be trimmed may be cut by the upper cutter 2022, and then the cut object may be crushed by the upper cutter 2022 and the upper cutter 2022. Through the arrangement, the pruning effect can be achieved, and the pruning efficiency is improved.
