Abstract

The utility model belongs to the field of wood felling tool technology, disclosing a felling tree scissors, which is mainly characterized in that the utility model comprises a scissors hook, a scissors body with a blade and a scissors back, a fixed shaft, a first scissors handle and a second scissors handle; wherein, a pulling sheet frame whose end is fixed with the first scissors handle and the second scissors handle is capable of slipping on the end is arranged between the first scissors handle and the second scissors handle; and a high pressure oil cylinder against the second scissors handle is arranged at the pulling sheet frame. The utility model solves the problems that the prior wood felling tool has the disadvantages of low efficiency, inconvenient use and carrying, moreover, wasting the energy; the utility model is capable of being widely used in the field of wood felling.

Description

The scissors of cutting down trees

Technical field

The utility model belongs to trees tree felling tool technical field, relates in particular to the scissors of cutting down trees.

Background technology

Wood saw, chopper etc. are adopted in traditional trees felling or pruning mostly, and this instrument is not only wasted time and energy, and inefficiency.Fuel oil power saw and electric saw complex structure not only waste energy, and cause environmental pollution, and are easy to have an accident.

The utility model content

Technical problem to be solved in the utility model just provides the scissors of cutting down trees of a kind of high efficiency, easy to use and carry, energy savings.

For solving the problems of the technologies described above, the scissors technical scheme of cutting down trees provided by the utility model is: comprise that cutter colludes, has the cutter hub of the blade and the knife back, fixed rotating shaft, first shear shank and second shear shank, between described first shear shank and second shear shank, have end and first shear shank is fixed, second shear shank can slide pulling force sheet frame thereon, on described pulling force sheet frame, have the high-voltage oil cylinder of roof pressure second shear shank.

Its additional technical feature is: described cutter hub is wedge shape, and knife back thickness is greater than the thickness of blade; Described knife back thickness is greater than 3 centimetres; Between described first shear shank and second shear shank, have compression spring; Be fixed with the scissors dead lever in the described first shear shank end.

Provided by the utility modelly cut down trees scissors compared with prior art, have the following advantages: one, owing between first shear shank and second shear shank, have end and first shear shank is fixed, second shear shank can slide pulling force sheet frame thereon, the high-voltage oil cylinder that on described pulling force sheet frame, has roof pressure second shear shank, when cutting down and prune thicker trees, only need cutter colluded with cutter hub and be stuck on the trunk, start high-voltage oil cylinder, set greatly under the effect of cutter hub, to block and break; Its two because cutter hub is wedge shape, greater than 3 centimetres, not only cutter hub intensity increases knife back thickness, and cut-off part is had certain tension force, has guaranteed that trunk colludes an inclination to cutter, makes safer greater than the thickness of blade and knife back thickness; Its three owing to be fixed with the scissors dead lever, stand in the branch that can prune eminence on the ground in the first shear shank end.

Description of drawings

The structural representation of the scissors of cutting down trees that Fig. 1 provides for the utility model;

Fig. 2 colludes structural representation with cutter hub for the cutter of the scissors of originally cutting down trees.

Embodiment

Below in conjunction with the drawings and specific embodiments the cut down trees structure of scissors of the utility model is described in further details.

As shown in Figure 1, the scissors of cutting down trees, comprise that cutter colludes 1, has cutter hub 4 and first shear shank 5 and second shear shank 6 of the blade 2 and the knife back 3, cutter colludes 1, cutter hub 4 and first shear shank 5 and second shear shank 6 be by fixed rotating shaft 7 rotating being fixed together, between first shear shank 5 and second shear shank 6, have pulling force sheet frame 8, the end of pulling force sheet frame 8 and first shear shank 5 are fixing, second shear shank 6 can slide on pulling force sheet frame 8, high-voltage oil cylinder 9 on pulling force sheet frame 8, push rod 13 roof pressures of high-voltage oil cylinder 9 are on second shear shank 6.

As shown in Figure 2, safe in utilization in order to guarantee, collude at cutter and to have blade groove 10 in 1.In order to increase cutter hub intensity, and cut-off part is had certain tension force, guaranteed that trunk colludes an inclination to cutter, make safelyr, cutter hub 4 is wedge shape, and the thickness of the knife back 3 is greater than the thickness of blade 2, and the thickness of the knife back 3 is more preferably greater than 3 centimetres.

Between first shear shank 5 and second shear shank 6, have compression spring 11, guaranteed to automatically spring open after first shear shank 5 and second shear shank 6 merge.

In order to prune the branch of eminence on the ground, be fixed with scissors dead lever 12 in first shear shank, 5 ends, certainly, scissors dead lever 12 also can be fixed on the end of second shear shank 6.

During use, with cutter collude 1, the cutter hub 4 that has the blade 2 and a knife back 3 is stuck on the trunk, starts high-voltage oil cylinder 9, push rod 13 roof pressures are at second shear shank 6, cutter colludes 1, cutter hub 4 rotates along fixed rotating shaft 7, and the trunk card is disconnected.Trunk colludes an inclination of 1 to cutter under the power of the top of the knife back 3, controlled the toppling direction of trunk, makes operation safe.

Claims

1. the scissors of cutting down trees, comprise that cutter colludes, has the cutter hub of the blade and the knife back, fixed rotating shaft, first shear shank and second shear shank, it is characterized in that: between described first shear shank and second shear shank, have end and first shear shank is fixed, second shear shank can slide pulling force sheet frame thereon, on described pulling force sheet frame, have the high-voltage oil cylinder of roof pressure second shear shank.

2. the scissors of cutting down trees according to claim 1 is characterized in that: described cutter colludes and has the blade groove.

3. the scissors of cutting down trees according to claim 1 is characterized in that: described cutter hub is wedge shape, and knife back thickness is greater than the thickness of blade.
