Abstract

The utility model relates to a graft cutter with high pressure air as the dynamic, which comprises a cylinder blade head, a handle, an air pipe, an air valve, and an air storage cylinder. The cylinder blade head provides motivation for the graft cutter. The cylinder blade head comprises a cylinder drum, a cylinder axle, a piston, a front end cap, a rear end cap, a seal ring and a reset spring; the front and rear ends of the spring are fixed with a bolt. The utility model is characterized in that: two claws and a cutting blade are positioned at the corresponding component of the cylinder. When the air valve is opened, the high pressure air enters into the cylinder via an cylinder air inlet, the pressurized air propels the piston and the cylinder axle move towards the low pressure end, thus pushing the cutting blade to move forward and switching off the graft in between the cutting blade and the claw; when the air valve is closed, the cylinder discharges the air and the reset spring shrink back to realize the reset of the cutting blade. With advantages of little noise and no pollution, the utility model can be adopted as a gardening tool for pruning the high branches by standing on the ground.

Description

Cut a device

Technical field

The utility model relates to a kind of garden instrument, a kind of device of cutting.

Background technology

A device of cutting of prior art is broadly divided into the hand pruner class; Electric shrub and hedge trimmer, the power saws class; The gasoline engine shrub and hedge trimmer, gasoline engine saw class.The shortcoming of hand pruner class is that operation is arduous, and efficient is low; The shortcoming of electric shrub and hedge trimmer and power saws class is the restriction that will be subjected to power supply, if join the accumulate pond, the capacity in accumulate pond is very limited, and noise is big; The shortcoming of gasoline engine shrub and hedge trimmer and gasoline engine saw class is that noise is big, waste gas is arranged, and their common drawback is to be inconvenient to prune the eminence branch.

Summary of the invention

It is a kind of device of cutting of power with gases at high pressure (as oxygen and nitrogen) that the purpose of this utility model provides a kind of, be fit to prune the branch bar of 10 to 100 millimeters of diameters, it is little to have noise, and free of contamination advantage is a kind of new tool that can directly prune eminence branch bar in ground.

The purpose of this utility model is achieved in that a kind of device of cutting, it comprises: the cylinder cutter head, handle, tracheae, air valve, gas bomb is characterized in that: described cylinder cutter head includes cylinder and cutter and colludes pawl, cutter and colluding on the corresponding component that pawl is fixed on cylinder, the reciprocating motion of cylinder can promote cutter and collude pawl and do to shear and homing action.

Described tracheae is flexible flexible pipe, is that pressed gas enters air valve and cylinder by gas bomb, and the passage of cylinder exhaust.

Control cylinder air inlet at any time of described air valve or exhaust.

Described gas bomb can be stored the gas of a certain amount of elevated pressures.

Owing to adopted technical scheme described in the utility model, when the branch bar of pruning trees, do not use gasoline or accumulate pond, only use innocuous gas such as compressed air, thus can combustion gas, not only environmental protection, and also noise is little.

Embodiment

As shown in Figure 1, a device of cutting of the present utility model mainly contains cylinder cutter head (1), handle (5), and tracheae (2), air valve (4), gas bomb (3) five parts are formed, and wherein the cylinder cutter head is the power section of cutting off the branch bar; Handle is that the operator arranges the intermediate tool that the cylinder cutter head realizes cutting branch; Tracheae is with the pipeline of gases at high pressure by air valve input cylinder and cylinder exhaust; Air valve is the office of control air inlet and exhaust; Gas bomb is the container that stores gases at high pressure.

As shown in Figure 2, the cylinder cutter head comprises cylinder barrel (11), cylinder axle (12), piston (7), drive end bearing bracket (9), rear end cap (6), sealing ring (13), back-moving spring (8), spring front end set bolt (10), spring rear end set bolt (14).The cylinder barrel wall is fixed with two and colludes pawl (11A), and cylinder axle front end is fixed with cutting knife (12B) (can certainly cylinder barrel wall fixed cutting tool, cylinder axle fixed hook pawl, just other parts also change simultaneously).When air valve is opened (as Fig. 3), when gases at high pressure entered cylinder by the air inlet of cylinder barrel, pressed gas promoted piston and the cylinder axle advances towards low-pressure end, advances thereby promote cutting knife, cuts off to place cutting knife and a bar that colludes between the pawl; When air valve is closed (as Fig. 4), the cylinder exhaust, back-moving spring shrinks, and forces cutting knife to reset.

Handle portion plays handled easily and protection behaviour person's effect between cylinder cutter head and operator, it comprises handle (17), cross joint block one (15), cross joint block two (16).In order to prune the branch bar of differing heights, can adopt expansion link, for cut different towards the branch bar and when avoiding work cylinder enormous function force reaction can make up at the cross piece of installing between cylinder and the handle as (15) among Fig. 2 and (16) shown in human body.

Tracheae is a pipeline of carrying gases at high pressure, is made up of for two sections to gas bomb to cylinder and air valve air valve, and tracheae will have enough length and good flexibility is arranged, and can make helix.

The air valve that uses in the device of cutting of the present utility model is a kind of high pressure valve, its structural principle as shown in Figures 3 and 4, it comprises: body (19), switching shaft (20), turn-knob (22), silencer (18), Fig. 3 is the fundamental diagram of air valve when opening, and the right (19C) screw connects gas cylinder by tracheae, and the left side (19D) screw connects cylinder by tracheae, when turn-knob was threaded to a certain angle, pressed gas passed switching axis hole (20E) by gas cylinder to (19C) and enters cylinder; Fig. 4 is the fundamental diagram of air valve when closing, the right (19C) screw connects gas bomb, and the left side (19D) screw connects cylinder, when turn-knob is threaded to another angle, pressed gas is by (19C) pathway closure to (19D), and cylinder residual air is discharged by (19D) to (20F) to (18).

Of the present utility modelly cut the gas bomb that a device uses and be gas cylinder, can directly adopt nitrogen cylinder on the market.

Claims

1. cut a device for one kind, it comprises: the cylinder cutter head, handle, tracheae, air valve, gas bomb is characterized in that: described cylinder cutter head includes cylinder and cutter and colludes pawl, cutter and colluding on the corresponding component that pawl is fixed on cylinder, the reciprocating motion of cylinder can promote cutter and collude pawl and do to shear and homing action.

2. a device of cutting according to claim 1, it is characterized in that: described tracheae is flexible flexible pipe, is that pressed gas enters air valve and cylinder by gas bomb, and the passage of cylinder exhaust.
