Description

Pruning device capable of preventing branches from falling randomly

Technical Field

The utility model relates to the field of machinery, in particular to a pruning device for preventing branches from falling randomly.

Background

Garden plants, green belts beside roads, etc. often need to be trimmed. The common tool for high trees is a high branch scissors, the shearing structure of the high branch scissors is similar to that of daily scissors, and the branches are trimmed only by pulling a rope. The shearing structure of the existing high branch shears is shown in fig. 1, but when the high branch shears shear shears, the shears can generate outward component force on branches 18, so that the high branch shears are only suitable for shearing soft and thin branches, namely branches with the diameter of less than 5mm are usually sheared, branches exceeding 5mm are hard due to higher lignification, the shearing cuts are easily pushed out by the outward component force when shearing, and the outward component force also needs more force to shear the branches, and most branches needing to shear are usually between 2 mm and 30mm, so that the situation that the branches are difficult to shear is often encountered when shearing the branches.

In addition, after cutting the branches, the branches can directly fall down, easily smash pruning personnel or passers-by, and for this reason, there is also a patent to increase clamping structure, like the pruning device of a tree high altitude branch that CN218302405U discloses etc. but this kind of device adopts electric structure, leads to the high branch to cut the top heavier, needs pruning personnel very big strength to maintain balance, hardly operates. In addition, branches of a plurality of trees are usually pruned during pruning, and an electric structure is adopted, so that the electric power is limited, and long-term maintenance operation is difficult.

Example 1

The pruning device for preventing branches from falling randomly as shown in fig. 2 comprises a pruning structure 1 and a long rod 2; the pruning structure 1 comprises a connecting part 3, a fixed cutter 4, a shearing groove 41, a movable cutter 5, a sliding chute 6, a vertical guide hole 7, a sliding block 8, a baffle plate 9, a branch clamping plate 10, a first spring 11, a first T-shaped groove 12, a first T-shaped sliding block 13, a Z-shaped spanner 141, a pull rope 14, a second spring 15, a second T-shaped groove 16 and a second T-shaped sliding block 17.

The fixed knife 4 is fixed at the top of the connecting part 3, the fixed knife 4 is 7-shaped, the connecting part 3 is connected with the movable knife 5 in a sliding way, a transverse first T-shaped groove 12 is formed at the bottom of the movable knife 5, a first T-shaped sliding block 13 is arranged in the first T-shaped groove 12, the bottom of the first T-shaped sliding block 13 is hinged with the inner end of a Z-shaped spanner 141, the Z-shaped spanner 141 is connected on the connecting part 3 in a rotating shaft way, and the outer end of the Z-shaped spanner 141 is connected with a pull rope 14. The fixed blade 4 is formed with a shearing groove 41 which cooperates with the movable blade 5.

When the branches 18 need to be trimmed, as shown in fig. 3, the branches are clamped between the fixed cutter 4 and the movable cutter 5, then the pull rope 14 is pulled, the Z-shaped wrench 141 rotates around the shaft joint as the center of a circle, and the movable cutter 5 is pushed upwards, so that the movable cutter 5 moves upwards, and the branches 18 are sheared, as shown in fig. 4. Because the moving blade 5 and the fixed blade 4 are parallel and vertical to the branches 18, all shearing forces are concentrated in the vertical direction of the branches, so that the branches are not easy to slide and are easier to shear.

In order to prevent branches from directly falling to injure pedestrians or pruning personnel after being sheared, a chute 6 is formed on the connecting part 3, and a vertical guide hole 7 is formed on one side of the chute 6; the movable knife 5 is positioned in the chute 6 and is connected with a baffle 9 through a connecting sliding block 8 penetrating through the vertical guide hole 7; a branch clamping plate 10 is slidably connected between the baffle 9 and the connecting part 3, and the bottom of the branch clamping plate 10 is connected with the connecting sliding block 8 through a first spring 11. When the movable knife 5 moves upwards, the branch clamping plate 10 moves upwards along with the branches 18, then the movable knife 5 moves upwards to cut off the branches 18, the branch clamping plate 10 compresses the spring at the bottom and clamps the branches 18, then the staff maintains the tension state of the pull rope 14, the pruning structure 1 is tilted to a branch collecting vehicle or other preset positions, and the pull rope 14 is loosened to enable the branches 18 to fall down.

In order to keep the movable knife in an open state in a normal state, the bottom of the movable knife 5 is connected with the connecting part 3 through an elastic structure. The elastic structure is a second spring 15 or an elastic rope, so that when the pull rope is not pulled, the movable knife 5 is pulled downwards by the elastic structure, and the shear opening is in an open state.

In order to enable the branch clamping plate 10 to stably slide up and down, a second T-shaped groove 16 is formed in the inner side surface of the baffle plate 9, a second T-shaped sliding block 17 is arranged in the second T-shaped groove 16 in a sliding manner, and the second T-shaped sliding block 17 is fixedly connected with the branch clamping plate 10.

The pruning structure 1 and the long rod 2 are detachably connected through threads, so that long rods with different lengths can be adopted according to different tree heights.

Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the scope of the present utility model, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
