[0002] Bamboo charcoal processing is a process of producing bamboo charcoal by high-temperature carbonization of bamboo, and pruning of bamboo is an important link in bamboo charcoal production, especially the treatment of branches, which not only needs to remove unnecessary parts of bamboo, but also needs to retain enough nodes to ensure that the shape of bamboo is suitable for subsequent carbonization. The branches on the bamboo not only occupy the effective material of the bamboo, but also may affect the quality of the bamboo charcoal during the carbonization process. Traditional branch pruning mostly relies on manual operation, which has problems such as low efficiency, high labor cost, and uneven pruning, and due to the different shapes of bamboo, it is difficult to ensure the precision and consistency during manual pruning. Therefore, there is an urgent need for an efficient and automated branch pruning device for bamboo charcoal processing. SUMMARY

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this application. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0021] Example: Figures 1-6 As shown, a branch pruning device for bamboo charcoal processing includes a pruning seat, with limiting mechanisms at both ends of the pruning seat for limiting the bamboo; the pruning seat is also provided with a branch trimming mechanism for trimming the bamboo branches.

[0022] The pruning seat includes a bracket 101 and a pruning cylinder 102, which is mounted on the bracket 101 and is cylindrical. The pruning mechanism includes a second gear ring 114 rotatably connected to the pruning cylinder 102 and a pruning motor 116 mounted on the bracket 101. A second gear 117 is mounted on the pruning motor 116 and meshes with the second gear ring 114. A pruning rod 113 is mounted on the second gear ring 114, and a pruning shear 121 is detachably mounted on the pruning rod 113. The pruning shear 121 is tangentially fitted to the surface of the bamboo and is used to prune branches.

[0023] When the worker inserts the bamboo into the pruning cylinder 102, the limiting assemblies at both ends of the pruning cylinder 102 center and clamp the bamboo, and when the position of the bamboo is adjusted to be appropriate, the position of the pruning rod 113 is adjusted so that the pruning knife 121 is attached to the surface of the bamboo, and then the pruning motor 116 is started, the pruning motor 116 drives the second gear 117, the second gear 117 drives the second gear ring 114 to rotate, the second gear ring 114 drives the pruning rod 113 to rotate synchronously, the pruning rod 113 drives the pruning knife 121 to rotate synchronously, and when the pruning knife 121 rotates around the bamboo, the blade of the pruning knife 121 will cut off the branches of the bamboo, and since the pruning knife 121 is attached to the surface of the bamboo and the blade of the pruning knife 121 is slightly away from the trunk of the bamboo, the blade of the pruning knife 121 will not cut the trunk of the bamboo. While the pruning knife 121 is working, the worker slowly pushes the bamboo so that the pruning knife 121 can continuously prune the branches at the joints of the bamboo.

[0024] Through the above arrangement, on the one hand, bamboo of different sizes can be pruned, and on the other hand, only one pruning knife 121 is needed to completely prune the branches on both sides of the bamboo, without the need to set multiple pruning knives 121 and adjust the pose of the bamboo, greatly improving the work efficiency.

[0025] As shown in Figure 5 the adjusting mechanism includes a third gear ring 115 rotatably connected to the pruning cylinder 102, an adjusting motor 119 mounted on the support 101, a third gear 118 mounted on the adjusting motor 119, the third gear ring 115 meshing with the third gear 118, an adjusting handle 120 rotatably connected to the third gear ring 115, the adjusting handle 120 slidably connected to the pruning rod 113, and the pruning rod 113 rotatably connected to the second gear ring 114.

[0026] Since the diameter of the root of the same bamboo is larger than that of the tip, even when the same bamboo is pruned, the position of the pruning rod 113 needs to be adjusted to ensure the pruning quality, and therefore the adjusting mechanism is designed. When the pruning motor 116 is started, the adjusting motor 119 is also started, the adjusting motor 119 drives the third gear 118, the third gear 118 drives the third gear ring 115, the third gear ring 115 drives the adjusting handle 120, and if the diameter of the bamboo does not change, the rotational speed of the adjusting motor 119 is controlled to be the same as that of the pruning motor 116, and at this time, the posture of the pruning rod 113 does not change, and if the diameter of the bamboo gradually decreases, the rotational speed of the adjusting motor 119 is controlled to be slightly lower than that of the pruning motor 116, so that the rotational speed of the second gear ring 114 is slightly higher than that of the third gear ring 115, and at this time, under the action of the adjusting handle 120, the pruning rod 113 starts to rotate, so that the pruning knife 121 is always attached to the surface of the bamboo, and vice versa.

[0027] By setting an adjustment mechanism, the pruning shears 121 can ensure sufficient pruning quality when pruning the same bamboo, regardless of how its diameter changes, to prevent the branches on the bamboo trunk from becoming too long and affecting subsequent carbonization.

[0028] like Figure 3 As shown, the limiting mechanism includes a fixed ring 105 mounted on the trimming cylinder 102, a movable ring 104 rotatably connected to the fixed ring 105, a plurality of second support cylinders 107 rotatably connected to the movable ring 104, and a plurality of first support cylinders 106 rotatably connected to the fixed ring 105; the limiting mechanism also includes a plurality of limiting rods 109, one end of a limiting rod 109 is mounted on a first support cylinder 106, and the other end is mounted on a second support cylinder 107, and the plurality of limiting rods 109 form a "well" shaped limiting frame; a synchronizing rod 103 is mounted on two movable rings 104 to synchronize the movements of the two movable rings 104.

[0029] After the bamboo is inserted into the pruning cylinder 102, the worker moves the movable ring 104. As the movable ring 104 rotates relative to the fixed ring 105, the second support cylinder 107 begins to move synchronously, thereby gradually reducing the size of the grid-shaped central hole formed by the multiple limiting rods 109. This centering and clamping of the bamboo ensures that the bamboo and the pruning cylinder 102 are coaxially aligned, ensuring the fit between the pruning shears 121 and the bamboo. When the diameter of the bamboo decreases, further rotation of the movable ring 104 ensures the limiting effect of the limiting rods 109.

[0030] like Figure 3 As shown, a conveyor motor 108 is installed on the second support cylinder 107. The conveyor motor 108 is connected to the corresponding limiting rod 109 in a transmission connection. The surface of the limiting rod 109 is covered with an anti-slip rubber layer.

[0031] After the limiting rod 109 limits the bamboo, due to the anti-slip rubber layer, the bamboo cannot slide along the axial direction of the trimming cylinder 102 when it is manually pushed. At this time, the conveying motor 108 is started, and the conveying motor 108 drives the limiting rod 109 to rotate, so that the limiting rod 109 can be rotated to realize the axial transmission of the bamboo.

[0032] like Figure 3 As shown, a first gear ring 110 is installed on the movable ring 104, a limit motor 111 is installed on the bracket 101, and a first gear 112 is installed on the limit motor 111. The first gear 112 meshes with the first gear ring 110.

[0033] When the bamboo needs to be clamped, the limiting motor 111 is started, the limiting motor 111 drives the first gear 112, the first gear 112 drives the first gear ring 110, and the first gear ring 110 drives the movable ring 104 to rotate, so as to replace manual operation, and the precision is higher and the labor intensity is smaller.

[0034] The utility model is not limited to the above-mentioned specific implementation, and the skilled person in the art can make various changes without creative labor based on the above-mentioned concept, which all fall within the protection scope of the utility model.
