Description

Technical Field

[0001] The utility model relates to the technical field of tree pruning, in particular to an electric forest tree and branch pruner. Background Art

[0002] When forestry trees grow too tall, it is necessary to promptly cut off broken branches, mechanically damaged branches and super-high branches, retain the main branches, and trim excess small side branches. On the one hand, this is to ensure the smooth appearance of the trees, and on the other hand, it can reduce water evaporation from the trees.

[0003] After searching, the utility model with announcement number CN218680264U discloses a forestry tree pruning device. The utility model is provided with a flipping component in the rectangular groove of the extension tube. The flipping component can be used to control the flipping of the fixed seat with the pruning component installed inside, thereby controlling the angle between the fixed seat and the extension tube, so that the pruning component inside the fixed seat can perform horizontal pruning or inclined pruning, and the pruning of the branches on the upper side of the trunk is relatively simple and quick.

[0004] The device also has the following disadvantages during use: when in use, the pruning blade is lifted to prune the branches. When used for higher trees, the pruned branches will fall under the action of their own gravity. If they are not handled, they are very likely to hurt others and are inconvenient to use. In response to the above problems, the utility model document proposes an electric forest branch pruner. Utility Model Content

In the above technical scheme, the first cutter 2 and the second cutter 3 can be staggered with each other through the setting of the cushion block 14, so that the first cutter 2 and the second cutter 3 can cooperate to cut off the branches.

[0048] However, as is well known to those skilled in the art, the working principle and wiring method of the motor 10 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.

[0049] The working principle and use process of the technical solution are as follows: when in use, the mounting base 1 can be lifted by holding the connecting rod 7, and then moved to the bottom of the miscellaneous branches so that the miscellaneous branches are located between the two clamping plates 4, and the motor 10 is started, and the motor 10 can drive one of the first gears 9 to rotate, and the rotation of the first gear 9 can drive the first cutter 2 to rotate, and at the same time, the second cutter 3 is driven to rotate in the opposite direction through the other first gear 9, and the miscellaneous branches can be cut off by the reverse rotation of the first cutter 2 and the second cutter 3;

[0050] When the first gear 9 rotates, the inner screw 11 can be driven to rotate through the second gear 12. The rotation of the inner screw 11 can drive the outer screw 16 to move into the inner screw 11. The V-shaped wedge block 6 can be driven to approach the mounting seat 1 through the second spring 20 and the fixed block 17. The movement of the V-shaped wedge block 6 can drive the two clamping plates 4 to approach each other until the outer screw 16 drives the second sliding rod 18 to move on the fixed block 17 to compress the second spring 20, so that the miscellaneous branches can be clamped to prevent them from falling.
