Embodiment 1

Refering to fig. 1 and Fig. 2, in the present embodiment, a kind of averruncator is proposed, including shear knife 1 and for driving shear knife 1 Mobile cylinder 2.

As shown in figure 3, shear knife 1 includes knife handle 3 and the edge of a knife 4 positioned at 3 top of knife handle.Wherein, knife handle 3 is settable in circle Bar shape.

As shown in Figure 4 and Figure 6, cylinder 2 includes hollow cylinder body 5 and the gas cylinder 6 for storing gas source, and gas cylinder 6 includes Stomata, venthole are connected with the bottom of cylinder body 5.Wherein, venthole may be disposed at the top of gas cylinder 6, and the bottom of cylinder body 5 can be set It is equipped with air inlet, venthole can be connected by tube body 7 (including hose or hard tube) with air inlet, specifically, can set on tube body 7 It is equipped with solenoid valve, passes through the connection or partition between solenoid valve control venthole and air inlet.Simultaneously, it is contemplated that environmental protection etc. because Element, gas cylinder 6 can be using the bombs for being compressed with carbon dioxide.

Referring to Fig. 3 and Fig. 4, out of the insertion of the top of cylinder body 5 cylinder body 5, knife handle 3 and the sliding of cylinder body 5 connect for the bottom of knife handle 3 It connects.

Wherein, the bottom of knife handle 3 is tightly connected by the inner wall of sealing element 8 and cylinder body 5.

The edge of a knife 4 is sticked on the branch for needing to shear；Venthole is opened, so that the gas in gas cylinder 6 enters cylinder body 5 It is interior；Under the action of gas source, the air pressure of 5 bottom of cylinder body increase moves up knife handle 3,4 crush-cutting branch of the edge of a knife to Complete the work of cutting.

In the present embodiment, cylinder 2 further includes having shell 17, and cylinder body 5 and gas cylinder 6 are respectively positioned in shell 17, and the edge of a knife 4 is located at It the top of shell 17 and stretches out in except shell 17.

It as depicted in figs. 1 and 2, is the work for preferably completing branch cutting, the top of shell 17 may be provided with for hanging The hook 9 being placed on branch.Hook 9 is placed on the branch that need to be cut off, it is convenient that the position of the edge of a knife 4 is positioned；Later, The edge of a knife 4 compresses branch under the action of cylinder 2 and drives branch mobile to hook 9, and during this, hook 9 can withstand branch And the scope of activities of branch is limited, finally, under the collective effect of the edge of a knife 4 and hook 9, so that branch is cut off.

In the present embodiment, it may be provided with locking plate 10 on hook 9, the tail end and shell 17 of locking plate 10 are rotatablely connected, locking plate Spring can be connected on 10, spring is for driving the top of locking plate 10 to stick on hook 9.It is formed between locking plate 10 and hook 9 One closed-loop, so that when cutting off, hook 9 will not be slipped from branch.Wherein, hook 9 and locking plate 10 combine Made of structure it is identical as snak link.

For convenience of the gripping of averruncator, the bottom of shell 17 is provided with support rod 11, the top of support rod 11 and shell 17 It is slidably connected.Wherein, the bottom of shell 17 may be provided with linear bearing 12, and support rod 11 passes through linear bearing 12 and slides therewith Connection.

To prevent from getting an electric shock, support rod 11 selects insulating bar, specifically, can be made of insulating material.Meanwhile for convenience of cutting The branch of different height, support rod 11 select telescopic rod.

If carrying out control words by switch of the solenoid valve to venthole, just also need using elements such as power supply, conducting wires, and This can make the structure of averruncator entirety become complicated.To be further simplified structure, averruncator can be arranged as follows:

As shown in figure 4, may be provided with the link mechanism 13 driven by support rod 11 in shell 17, it is arranged on link mechanism 13 There are several rotation points being rotatablely connected with shell 17.

As shown in Figure 5 and Figure 6, one end of link mechanism 13 is fixedly connected with the top of support rod 11, link mechanism 13 The other end is provided with the sealed piece 14 for closing venthole, wherein by pulling 11 drive link mechanism 13 of support rod to make Sealed piece 14 opens venthole.When support rod 11 moves down and opposite sliding occurs between shell 17, link mechanism 13 It will be moved under the action of support rod 11, sealed piece 14 skids off stomata and by venthole under the action of link mechanism 13 It opens.

Link mechanism 13 is a kind of common mechanism in machinery, and in the present embodiment, the form of link mechanism 13 can root According to being selected.

It has been pre-adjusted the length of support rod 11, and has carried out locking to it and length is kept to fix, can so have been prevented because of external force There is the case where elongating or shortening of support rod 11, avoid causing using inconvenience；Hook 9 is placed on branch to be cut off； Support rod 11 is pulled, links up with and reclines and acted on branch on the inside of 9 top, at this point, manpower and branch are respectively acting on height The both ends of secateurs then cause venthole to be opened so that opposite sliding occurs between support rod 11 and shell 17；Outlet After hole is opened, the gas in gas cylinder 6 enters in cylinder body 5, so that knife handle 3 be driven to move up, final 4 crush-cutting branch of the edge of a knife is complete At the cutting work of branch.

When the operation cut off, it is only necessary to which manpower pulls support rod 11, easy to operate and laborsaving.

In the present embodiment, it may be provided in shell 17 for driving sealed piece 14 to reset to seal the return unit of venthole 15.After completing the work of branch shearing, branch just no longer applies active force to hook 9 and support rod 11, at this point, in return unit Under the action of 15, sealed piece 14 resets and closes venthole.Wherein, sealed piece 14 can be made into needle-shaped, meanwhile, on sealed piece 14 It may be provided with sealing ring, it can be with better seal venthole using sealing ring.

In the present embodiment, spring can be selected in return unit 15, and one end of spring is fixedly connected with the top of support rod 11, bullet The other end of spring is fixed in shell 17.Wherein, in averruncator when not worked, spring is in nature elongation state.

As shown in figure 4, may be provided with bleeder port 16 on cylinder body 5, bleeder port 16 is close to the top of cylinder body 5.Work as completion After the work of cutting, due to causing the air pressure inside it excessive there are the gas that gas cylinder 6 is filled in cylinder body 5, so that shear knife 1 It can not return.For this purpose, the top that can pull shear knife 1 that the sealing element 8 on knife handle 3 is made to be moved to bleeder port 16, at this point, cylinder The gas being charged in body 5 can be discharged from bleeder port 16, thus just can reduce the air pressure in cylinder body 5, facilitate shear knife 1 Return.

It will be appreciated by those skilled in the art that the accompanying drawings are only schematic diagrams of a preferred implementation scenario, module in attached drawing or Process is not necessarily implemented necessary to the utility model.

It will be appreciated by those skilled in the art that the module in device in implement scene can be described according to implement scene into Row is distributed in the device of implement scene, can also be carried out corresponding change and is located at the one or more dresses for being different from this implement scene In setting.The module of above-mentioned implement scene can be merged into a module, can also be further split into multiple submodule.

Above-described embodiment serial number is for illustration only, does not represent the superiority and inferiority of implement scene.

Disclosed above is only several specific implementation scenes of the utility model, and still, the utility model is not limited to This, the changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
